Description

Bead-bursting sanitary towel

Technical Field

The invention relates to the technical field of sanitary napkins, in particular to a bead-bursting sanitary napkin.

Background

The sanitary towel has high water absorbability and is mainly made of high polymer and high polymer composite paper made of cotton, non-woven fabric, paper pulp and other materials, wherein the sanitary towel is mainly divided into a surface layer which is adhered to skin, an absorption core layer for absorbing liquid and a bottom layer for preventing liquid from penetrating and for bonding and fixing.

Women are in a menstrual period and have low immunity, so that the women are easy to be infected by bacteria during the menstrual period, and when the women use the sanitary towel in the menstrual period, the sanitary towel is easy to grow various details and fungus microorganisms due to the fact that the absorption liquid is in a moist environment, and the surface layer of the sanitary towel is attached to the skin, so that the women are further easy to be infected by bacteria during the menstrual period, and the gynecological diseases are caused to be harmful to the health; for example, 2008.12.24 discloses an antibacterial and anti-infection sanitary towel with a patent number of CN100444903C, wherein the sanitary towel adopts a high-air-permeability non-woven fabric as an outer layer, a high-efficiency gel fiber layer as a middle layer and a porous funnel type dry cotton net casting film as an inner layer, and the middle layer contains antibacterial components prepared from Chinese medicines such as cortex dictamni, flos Magnoliae, borneol and the like; the sanitary towel can kill microorganisms such as bacteria and fungi, but the sanitary towel cannot prolong the drug effect to perform continuous sterilization and anti-inflammation effects.

When a woman uses the sanitary towel, the sanitary towel is better in use experience because the sanitary towel is attached to the skin so as to improve the comfort and ensure the health, and the surface of the sanitary towel is always in a clean state in the use process, so that the sanitary towel is easy to be favored by the woman; the water absorption of the sanitary towel directly affects the cleanliness of the surface of the sanitary towel, for example, the sanitary towel is not strong in water absorption, so that liquid cannot be absorbed in time, and is remained on the surface of the sanitary towel, and bacterial infection is easily caused while the experience of a user is affected, so that the health of a female user is affected; in the process of using the sanitary towel, the liquid always flows downwards under the action of gravity, and the position of the sanitary towel is relatively fixed after the sanitary towel is adhered and used, so that the liquid is concentrated on a part of the sanitary towel to be contacted and is difficult to be uniformly absorbed by the sanitary towel, and the liquid is remained on the surface of the sanitary towel;

The sanitary towel can absorb liquid in a concentrated manner, and meanwhile, the liquid cannot be absorbed into the absorption core layer of the sanitary towel rapidly due to uneven liquid absorption positions and low absorption efficiency, so that the liquid flows back or seeps out in the sanitary towel, and the sanitary towel is invalid in use; for example, patent No. CN101090689B published by You Ni corporation at 2011.03.02, in which a bulge portion provided on the skin-side surface of a sanitary napkin main body is easily sealed with a portion from the vaginal opening to the anus and the cleft portion of the buttocks, the sanitary napkin is formed into a surface-constituting member by covering a part of the surface sheet of the liquid-absorbing layer, in the surface-constituting member, a central elastic member is provided at a position apart from the sanitary napkin main body, side elastic members are provided at a height position between the central elastic member and the skin-side surface of the sanitary napkin main body, bulge portions are formed to stand on the skin-side surface, the width dimension of the top portion of the bulge portion is small, and upper side wall portions having opposite angles are formed from the top portion to extend toward the sanitary napkin main body; the raised portion of the sanitary napkin can be deformed to follow the shape of the body, and is easily adhered to the inside of the cleft portion of the buttocks, but the absorbency of the sanitary napkin cannot be improved when the sanitary napkin is deformed and adhered, so that there is still a case where liquid flows back and out of the sanitary napkin.

When the sanitary towel is used in daily life, as various activities are carried out by women, the contact position of liquid and the sanitary towel is changed, the sanitary towel is easy to absorb the liquid in a concentrated manner at the local periphery after the contact position is changed, for example, a user who is ready to enter a sleep state at night is in a lying state, the liquid preferentially flows downwards to contact the peripheral position of the sanitary towel under the action of gravity, so that the liquid cannot be uniformly diffused and quickly absorbed when the sanitary towel absorbs the liquid, and the liquid retained on the surface or in the sanitary towel is caused to flow back or leak outwards, so that the sanitary towel in a use state is invalid; for example, a sanitary napkin having an absorbent region, a high stiffness portion region, side regions and overlapping leakage preventing sidewalls, as disclosed in 2004.12.22 by the company You Ni, CN 1180753C; the main absorption area of the sanitary towel is difficult to twist, and the side areas are provided with boundary areas, so that the influence of the side wing parts of the sanitary towel on the absorbability of the sanitary towel is avoided when the sanitary towel sleeps at night, but the sanitary towel cannot adapt to the change of the contact area between liquid and the sanitary towel caused by the change of the human body state, and therefore, the contacted liquid cannot be uniformly diffused and quickly absorbed in time.

The thickness of the water-soluble protective layers wrapped on the surfaces of the first explosive beads 61 is uneven, namely, the thicknesses of the water-soluble protective layers of adjacent first explosive beads 61 are uneven, and the dissolution speeds of the water-soluble protective layers of adjacent first explosive beads 61 with uneven thicknesses are also different when the water-soluble protective layers are contacted with liquid, so that the antibacterial and anti-inflammatory effects can be prolonged by asynchronous dissolution, and further, the water-soluble protective layers can be always in the optimal antibacterial and anti-inflammatory effects in the use process; specifically, in the use process, when a user in an active state in daytime is guided by the diversion layer 3, the liquid is uniformly absorbed and locked by the first absorption core layer 41 and contacts with the first bursting beads 61, wherein the thinner water-soluble protective shell of the adjacent first bursting beads 61 is firstly dissolved and releases the inner antibacterial and anti-inflammatory components, and in the process that the antibacterial and anti-inflammatory components firstly dissolved in the first absorption core layer 41 are gradually volatilized to continuously reduce the antibacterial and anti-inflammatory effects, the thicker water-soluble protective shell is dissolved and kills bacteria and fungi when the antibacterial and anti-inflammatory effects are reduced, so that the antibacterial and anti-inflammatory effects of the bursting bead sanitary towel 1 in use are prolonged and enhanced.

The second bursting beads 62 are made of super absorbent resin, the second bursting beads 62 are used for enhancing the water absorption of the bursting bead sanitary towel 1, and enabling the second absorption core layer 42 to absorb liquid more uniformly, namely the second bursting beads 62 are subjected to stress cracking, and the residual second bursting beads 62 which are not subjected to stress cracking can improve the water absorption at the position, so that the second absorption core layer 42 is cracked and the water absorption at the position where the second bursting beads are cracked are different, and the water absorption at different degrees forms a wet gradient effect in the second absorption core layer 42, namely the phenomenon that the liquid in the low water absorption area moves to the high water absorption area, so that the second absorption core layer 42 is more uniform and full when absorbing the liquid, and the liquid backflow and the leakage caused by local excessive absorption and the local waste caused by uneven absorption after use are avoided;

Specifically, when a user in an active state during the daytime, for example, the user is sitting or sitting posture is changed, the pop-up ball sanitary towel 1 is forced to fit the skin of the user, meanwhile, liquid is pulled by gravity or pulled by the action of the user and concentrated to be contacted with the pop-up ball sanitary towel 1, and the second pop-up balls 62 in the stressed position in the second absorbent core layer 42 are stressed and ruptured, so that the water absorption of the remaining second absorbent core layer 42 which is not contacted with the liquid is greater than that of the second pop-up balls 62 in the stressed position under the action of the second pop-up balls 62 which are not ruptured, thereby forming a wet gradient effect in the second absorbent core layer 42, and further enabling the concentrated liquid to move from the liquid absorption area to the non-liquid absorption area in the second absorbent core layer 42, namely, the liquid moves from the ruptured area of the second pop-up balls 62 to the non-ruptured area, which is beneficial to make the second absorbent core layer 42 more uniform when absorbing the liquid and improve the water absorption of the second absorbent core layer 42; it should be noted that, the habit difference of each person may cause the cracking position of the second pop-up bead 62 to change, and the stress cracking of the second pop-up bead 62 may be more fit to the difference between the contact positions of the liquid and the pop-up bead sanitary towel 1 caused by the habit of the person.

The bead blasting sanitary towel 1 is in a back-shaped structure 7, the bead blasting sanitary towel 1 is divided into an inner side and an outer side, the inner side and the outer side of the bead blasting sanitary towel 1 are different in water absorption, namely the outer side of the bead blasting sanitary towel 1 is larger than the inner side of the bead blasting sanitary towel 1 in water absorption, the inner side of the bead blasting sanitary towel 1 and the outer side of the bead blasting sanitary towel 1 are different in water absorption, so that a wetting gradient effect is formed, namely liquid in a region with small water absorption moves to a region with large water absorption; the user in the movable state in daytime is in a standing or sitting state, liquid can be preferentially contacted and adsorbed with the middle position of the pop-up ball sanitary towel 1 under the action of gravity, so that the situation that the excessive absorption of the middle position cannot be timely diffused to the periphery is easily caused, and liquid reflux and extravasation are generated in the pop-up ball sanitary towel 1, the water absorption of the outer pop-up ball sanitary towel 1 is larger than that of the inner pop-up ball sanitary towel 1, and the liquid in the middle position is adsorbed to the periphery, so that the situation that the liquid cannot be timely diffused to the periphery due to the concentrated absorption of the liquid and the middle position in the standing or sitting state is avoided, and the situation that the liquid reflux or extravasation is generated due to the excessive absorption of the liquid in the middle position is avoided; the middle position of the back-shaped structure 7 of the pop-up sanitary towel 1 is a slightly concave structure, so that liquid can be stably absorbed when the liquid contacts the surface layer 2 and the diversion layer 3, and liquid leakage caused by the fact that the liquid is concentrated and not absorbed by the surface layer 2 and the diversion layer 3 in time is avoided.

The surface of the first absorbent core layer 41 is provided with a plurality of flow equalizing grooves 411 with curved structures along the length direction, the flow equalizing grooves 411 can conduct liquid to two sides when the first absorbent core layer 41 absorbs locking liquid, so that the absorption area can be increased when the first absorbent core layer 41 absorbs liquid, the contact area between the first absorbent core layer 41 and the liquid can be further increased by the flow equalizing grooves 411 with curved structures, the uniformity and the water absorption efficiency when the first absorbent core layer 41 absorbs the liquid are further increased, and liquid backflow and extravasation caused by local excessive absorption and slow absorption of the first absorbent core layer 41 are prevented; and the uniform liquid absorption of the first absorbent core layer 41 simultaneously causes the second absorbent core layer 42 to uniformly absorb liquid and absorb water.

The fiber gap of the second absorbent core layer 42 is smaller than the fiber gap of the first absorbent core layer 41, so that a differential capillary effect can be formed, namely, the additional pressure in the fiber web with small gap is small, the additional pressure in the fiber web with large gap is large, and the pressure difference between the first absorbent core layer 41 and the second absorbent core layer 42 enables the liquid to flow directionally, namely, the liquid flows from the gap with large pressure to the gap with small pressure; thus, when the first absorbent core layer 41 absorbs liquid, the liquid of the first absorbent core layer 41 flows toward the second absorbent core layer 42, thereby avoiding liquid back flow and extravasation while the double layer absorption of liquid improves water absorption.

During use, a user in a daytime activity state unpacks the package to adhere the pop-up sanitary towel 1 to the surface of underpants; when a user is in a standing position or sitting position, liquid preferentially flows downwards to the middle position of the bursting bead sanitary towel 1 to contact and absorb under the action of gravity, the whole structure of the bursting bead sanitary towel 1 is in a back-shaped structure 7, the water absorption of the outer bursting bead sanitary towel 1 is greater than that of the inner bursting bead sanitary towel 1, namely, the liquid in a region with small moisture gradient effect moves to a region with large water absorption; the liquid can be preferentially contacted and adsorbed with the middle position of the bead-blasting sanitary towel 1 under the action of gravity, and the water absorption of the outer bead-blasting sanitary towel 1 is greater than that of the inner bead-blasting sanitary towel 1, so that the liquid at the middle position is adsorbed to the periphery, and the phenomenon that the liquid cannot be timely diffused to the periphery due to the concentration of the liquid and the absorption of the middle position under the standing or sitting state is avoided;

when the liquid contacts with the bursting bead sanitary towel 1, the liquid flows downwards to the middle position of the bursting bead preferentially under the action of gravity and contacts with the surface layer 2 and the diversion layer 3, after the surface layer 2 adsorbs the liquid to the diversion layer 3, the diversion layer 3 conducts the liquid along the length direction of the bursting bead sanitary towel 1 through the diversion groove, so that the contact area of the concentrated flowing liquid and the diversion layer 3 is increased, the liquid is uniformly conducted to the surface of the first absorption core layer 41, a plurality of curved flow equalizing grooves 411 are formed in the surface of the first core layer, and the liquid is diffused to two ends through the flow equalizing grooves 411 when contacting with the first absorption core layer 41, so that the contact area of the first absorption core layer 41 and the liquid is increased, and the water absorption and uniformity are further increased;

When the liquid contacts with the first absorbent core 41, the thicknesses of the water-soluble protective layers on the surfaces of the first bursting beads 61 at adjacent positions are different, so that the dissolving speeds are different when the liquid dissolves the water-soluble protective layers, and further the liquid antibacterial and anti-inflammatory components in the first bursting beads 61 are released and fused into the first absorbent core 41 in an unsynchronized manner, which is beneficial to prolonging the effective duration of the antibacterial and anti-inflammatory components and is always in the optimal antibacterial and anti-inflammatory effect;

after the first absorbent core layer 41 absorbs liquid, the liquid moves from the inside of the first absorbent core layer 41 to the inside of the second absorbent core layer 42 by the differential capillary effect of the first absorbent core layer 41 and the second absorbent core layer 42, thereby improving the water absorption of the bead-bursting sanitary napkin 1 and preventing the liquid from flowing back and leaking out; in the using process, according to the gesture change of a user, the contact absorption position of the liquid and the burst sanitary towel 1 is changed, the second burst beads 62 at the stressed position are stressed and ruptured along with the gesture change, so that the water absorption of the remaining second absorption core layer 42 which is not contacted with the liquid is larger than the ruptured area of the second burst beads 62 at the stressed position under the action of the second burst beads 62 which are not ruptured, thereby forming a wetting gradient effect in the second absorption core layer 42, and further enabling the concentrated liquid to move from the liquid absorption area to the liquid non-absorption area in the second absorption core layer 42;

While the second absorbent core layer 42 absorbs the liquid, the second bursting beads 62 fixedly adhered in the second absorbent core layer 42 are subjected to stress rupture, so that the residual second absorbent core layer 42 which is not contacted with the liquid is more water-absorbing than the rupture area of the second bursting beads 62 at the stress position under the action of the second bursting beads 62 which are not ruptured, thereby forming a wetting gradient effect in the second absorbent core layer 42, and further enabling the concentrated liquid to move from the liquid absorption area to the liquid non-absorption area in the second absorbent core layer 42.

The embodiment is suitable for the user in the daytime activity state, because the user in the daytime activity state is in a standing or sitting state, the liquid preferentially flows downwards to contact the middle position of the pop-up sanitary towel 1 under the action of gravity; in the embodiment, the bursting bead sanitary towel 1 with the back-shaped structure 7, namely the water absorption of the bursting bead sanitary towel 1 at the outer side is larger than that of the bursting bead sanitary towel 1 at the inner side to form a wetting gradient effect, so that the situation that a user moving in the daytime cannot timely diffuse to the periphery due to excessive absorption at the middle position is avoided, and liquid backflow and extravasation in the bursting bead sanitary towel 1 are avoided; the water-soluble protective layers with different thicknesses at adjacent positions can be dissolved in a non-synchronous manner to release the internal antibacterial and anti-inflammatory substances, so that the service life of the antibacterial and anti-inflammatory substances can be prolonged; meanwhile, the antibacterial substance is in a liquid state, so that the situation of dysmenorrhea can be relieved while the antibacterial substance is antibacterial and anti-inflammatory;

In this embodiment, when the user in sitting position or sitting position changes is subjected to the increased water absorption of the second burst bead 62 by fixing and bonding the second burst bead 62, the second burst bead 62 in the stressed position is stressed and ruptured, so that the water absorption of the remaining second absorbent core layer 42 which is not contacted with liquid is greater than the ruptured area of the second burst bead 62 in the stressed position under the action of the second burst bead 62 which is not ruptured, thereby forming a wet gradient effect in the second absorbent core layer 42, that is, the absorbed liquid moves from the ruptured area of the second burst bead 62 to the uncracked area, which is beneficial to making the second absorbent core layer 42 more uniform when absorbing the liquid and improving the water absorption of the second absorbent core layer 42, and the habit difference of each person can cause the ruptured position of the second burst bead 62 to change, and the stress rupture of the second burst bead 62 can be more suitable for the difference of the contact position between the liquid and the burst bead sanitary towel 1 caused by the habit of the person, that is more flexible in the larger area of the second absorbent core layer 42 according to the habit of the user, which is beneficial to improving the use experience; therefore, the embodiment is more suitable for being in a daytime activity state, and is particularly suitable for the user in a daytime sitting posture.

Example 2 this example is suitable for a user in a daytime active state, i.e. for making a daily use pop-up sanitary napkin 1, on the basis of example 1, as shown in figures 1 to 4 and 6.

A plurality of second bursting beads 62 are fixedly bonded in the second absorption core layer 42, the second bursting beads 62 are fixedly bonded and arranged along the periphery of the bursting bead sanitary towel 1, and the area of the middle part of the second bursting beads 62 which is not fixedly bonded is in a diamond structure; it should be noted that, in this embodiment, the second explosion bead 62 has high toughness and is not broken due to stress, and the diamond-shaped area where the second explosion bead 62 is not bonded is filled with the second absorbent core layer 42; the second explosion beads 62 are fixedly adhered around the second absorbent core layer 42, so that the water absorption at the peripheral position of the second absorbent core layer 42 is maximum, and thus, when the liquid is absorbed at the middle position of the second absorbent core layer 42, part of the liquid in the middle can be absorbed to the peripheral position, and the reflux and the extravasation caused by the excessive absorption liquid in the middle position are avoided; when the user moves in the daytime, because the user is in a standing or sitting state, the liquid can be preferentially contacted and adsorbed with the middle position of the pop-up sanitary towel 1 under the action of gravity, and the second pop-up beads 62 adsorb the liquid absorbed in the middle position in a concentrated manner to the periphery under the action of the second pop-up beads 62 with more positions around the pop-up sanitary towel 1, so that backflow or extravasation caused by excessive adsorption of the liquid at the middle position of the pop-up sanitary towel 1 due to standing or sitting state during the daytime sleeping state of the user is avoided.

The embodiment is suitable for a user in a daytime standing state, the liquid of the user standing in the daytime is preferentially contacted and absorbed with the middle position of the bursting bead sanitary towel 1 under the action of gravity, and the water absorption of the periphery of the bursting bead sanitary towel 1 is greater than that of the middle position by the diamond-shaped structure of the second bursting beads 62 which are fixedly adhered around the bursting bead sanitary towel 1 and the area of the second bursting beads 62 which are not fixedly adhered in the middle, so that the reflux and the extravasation caused by excessive absorption liquid in the middle position are avoided; because the contact and absorption positions of the liquid and the bursting bead sanitary towel 1 of the user in the standing position in the daytime are relatively fixed, the embodiment is suitable for the user in the daytime, and is particularly suitable for the user in the standing position in the daytime.

Example 3 this example is suitable for a user in a daytime active state, i.e. for making a daily use pop-up sanitary napkin 1, on the basis of example 1, as shown in figures 1 to 4, 7 and 9.

The bottom of the first absorbent core layer 41 and the top of the second absorbent core layer 42 are both provided with corresponding rectangular grooves 43, the rectangular grooves 43 are arranged along the length direction of the pop-up sanitary towel 1, namely the front-back direction of a user, a plurality of second pop-up beads 62 are movably mounted in the rectangular grooves 43, it is to be noted that in the embodiment, the second pop-up beads 62 have higher toughness and cannot be broken due to stress, the bottom of the first absorbent core layer 41 is fixedly adhered to the top of the second absorbent core layer 42, so that the corresponding rectangular grooves 43 form a closed cavity, a plurality of second pop-up beads 62 are placed in the closed cavity, and the second pop-up beads 62 can freely move in the closed cavity; the second bursting beads 62 freely moving in the closed chamber between the first and second absorbent core layers 41, 42 can increase the water absorption at different positions, i.e. can increase the water absorption in a movable manner;

When the user is in an active state in daytime, when the contact position of the liquid and the burst ball sanitary towel 1 is changed due to the difference of the posture change and personal habit of the user, the liquid moves downwards under the action of gravity to be in contact with the burst ball sanitary towel 1, and meanwhile, the second burst ball 62 is consistent with the liquid moving direction under the action of gravity, so that the water absorption can be always increased at the position where the liquid is in concentrated contact and absorption when the contact position of the liquid and the burst ball sanitary towel 1 is changed, and the liquid backflow or the liquid extravasation caused by the fact that the local liquid flow is too large to be absorbed in time when the contact position is changed due to the posture change or the habit difference of the user is avoided; for example, after the local first absorbent core layer 41 and the second absorbent core layer 42 are gradually saturated, or the first absorbent core layer 41 and the second absorbent core layer 42 cannot timely absorb all the liquid, the second bursting beads 62 move to the position to increase the water absorption and the contact area, so as to avoid the backflow or the extravasation of the liquid; the length of the combination of the plurality of second explosive beads 62 in the closed chamber is about half of that of the closed chamber.

after the first absorbent core layer 41 absorbs liquid, the liquid moves from the inside of the first absorbent core layer 41 to the inside of the second absorbent core layer 42 by the differential capillary effect of the first absorbent core layer 41 and the second absorbent core layer 42, thereby improving the water absorption of the bead-bursting sanitary napkin 1 and preventing the liquid from flowing back and leaking out; the second bursting beads 62 which are freely moved in the closed cavity between the first absorption core layer 41 and the second absorption core layer 42 are consistent with the movement direction of the liquid under the action of gravity while the second absorption core layer 42 absorbs the liquid, so that the water absorption can be always increased at the position where the liquid is intensively contacted and absorbed when the contact position of the liquid and the bursting bead sanitary towel 1 is changed, and the liquid backflow or the exosmosis caused by overlarge local liquid flow and incapability of timely absorbing when the contact position is changed due to the change of the posture or the habit difference of a user is avoided; the use is completed after the bursting bead sanitary towel 1 is full of absorbing liquid, so that the bursting bead sanitary towel 1 is used, and then a user removes and replaces the bursting bead sanitary towel 1.

The embodiment is suitable for the user in the daytime, the liquid of the user in the daytime is preferentially contacted and absorbed with the middle position of the pop-up sanitary towel 1 under the action of gravity in the standing or sitting state, but when the user in the daytime activity state frequently moves, the frequent movement in the daytime mainly changes in the front-back amplitude, and the liquid or the pop-up sanitary towel 1 is pulled, so that the contact position of the liquid and the pop-up sanitary towel 1 is unevenly changed; therefore, the movable second bursting beads 62 in the closed cavities with the strip-shaped structures can move according to the movement state change of the user, and the movable second bursting beads 62 can be consistent with the liquid change direction under the action of gravity, so that the water absorption of the concentrated absorption position of the converted liquid is increased, and the condition that the bursting beads are in backflow or extravasation of the liquid when the user frequently moves is prevented; therefore, the present embodiment is suitable for use persons who are in daytime activities, and is particularly suitable for use persons who are in daytime activities and frequently active.

The first absorbent core layer 41 is fixedly and adhesively arranged below the diversion layer 3, and the sizes of the first absorbent core layer 41 and the second absorbent core layer 42 are consistent with the diversion layer 3, so that the first absorbent core layer 41 can be ensured to fully absorb the liquid conducted by the diversion layer 3; it should be noted that the size of the bottom layer 5 should be not smaller than the second absorbent core layer 42, preferably slightly larger than the second absorbent core layer 42, so that the penetration of liquid is sufficiently prevented, and the larger part can be made of flexible materials, so that the user can be better protected when rubbing with the mouse, i.e. the groove at the root of the thigh in the use process; the utility model discloses a sanitary towel, including first absorption sandwich layer 41, second absorption sandwich layer 42, first absorption sandwich layer 41 and second absorption sandwich layer 42 are interior fixed bonding to be provided with second absorption sandwich layer 42, all fixed bonding installs burst bead structure 6 in first absorption sandwich layer 41 and the second absorption sandwich layer 42, burst bead structure 6 is used for improving the hydroscopicity of sanitary towel and plays antibiotic anti-inflammatory effect in the use, burst bead structure 6 divide into first burst bead 61 and second burst bead 62, fixed mounting has a plurality of first burst beads 61 in the first absorption sandwich layer 41, fixed mounting has a plurality of second burst beads 62 in the second absorption sandwich layer 42, can improve through first burst bead 61 and second burst bead 62 in the in-process of using burst bead sanitary towel 1's hydroscopicity and antibacterial property, it is noted that first burst bead 61 and second burst bead 62 diameter are not greater than first absorption sandwich layer 41 and the second absorption sandwich layer 42's height, avoid burst bead 1 because inside contain first burst bead 61 with second burst bead 62 causes the surface to feel smooth effect and avoid using.

The first explosion beads 61 contain antibacterial and anti-inflammatory components, the antibacterial and anti-inflammatory components are solid pasty extracts prepared from one or more of honeysuckle, rheum officinale leaves, radix stemonae, aloe and mugwort, and the antibacterial and anti-inflammatory components in the first explosion beads 61 are solid and are adhered in the first absorption core layer 41 to contact with air for gradual volatilization; specifically, in the use process, a user unpacks the package of the pop-up sanitary towel 1 first, and then, after unpacking, the plurality of first pop-up beads 61 are squeezed and exploded one by hand, so that the solid antibacterial and anti-inflammatory substances in the first pop-up beads 61 are released and then attached to the first absorbent core layer 41; after the first pop 61 is popped, the operator adheres the bottom layer 5 of the pop sanitary napkin 1 to the inner surface of underpants, thereby formally using the pop sanitary napkin 1;

the solid antibacterial and anti-inflammatory components in the first bursting beads 61 continuously kill various bacteria and fungi in the bursting bead sanitary towel 1 and prevent growth and reproduction in the process of gradually volatilizing after being released and attached to the first absorption core layer 41, thereby preventing users from being infected by bacteria or fungi when in use, and ensuring the health of the users.

The surface of the first explosion bead 61 is wrapped with a protective layer, and it should be noted that the protective layer is attached to the first explosion bead 61, so as to avoid damage to the first explosion bead 61 caused by shaking and striking between the first explosion bead 61 and the water-soluble protective layer in the transportation process, the protective layer is made of polyethylene glycol, and before use, a user breaks the protective layer and the first explosion bead 61 by hand to release antibacterial and anti-inflammatory components in the first explosion bead 61; it should be noted that, the protective layer made of polyethylene glycol material has good water solubility, that is, it will gradually dissolve in contact with liquid during menstrual period, so as to release the antibacterial and anti-inflammatory components inside, so that even if the user does not fully pinch the first explosion bead 61 before using, the protective layer can be gradually dissolved in subsequent use, thereby being beneficial to ensuring that the antibacterial and anti-inflammatory components in the first explosion bead 61 can be fully released; it should be noted that, when the first explosion beads 61 are not completely pinched, the first explosion beads 61 can form an asynchronous release of the antibacterial and anti-inflammatory components in the interior under the subsequent dissolution, so as to prolong the duration of the antibacterial and anti-inflammatory effects;

the protective layer made of polyethylene glycol can play a role in sealing the internal antibacterial and anti-inflammatory components, so that the antibacterial and anti-inflammatory effects in use are ensured, and the condition that the internal antibacterial and anti-inflammatory components are invalid due to long-term storage of the bead-bursting sanitary towel 1 is avoided; meanwhile, the first bursting beads 61 are protected, and the first bursting beads 61 are prevented from being damaged in the transportation process, so that the stability of antibiosis and antiphlogosis of the bursting bead sanitary towel 1 in use is ensured; specifically, during the use process, the liquid is absorbed and guided by the surface layer 2 and the diversion layer 3, so that the first absorbent core layer 41 uniformly absorbs and locks the liquid, the liquid contacts with the water-soluble protective layer when being absorbed by the first absorbent core layer 41, so as to gradually dissolve the water-soluble protective layer on the surface of the first explosion bead 61, after the water-soluble protective layer is dissolved, the first explosion bead 61 can be broken by only slight stress, so that the internal antibacterial and anti-inflammatory components are released, for example, during daily activities, when the user changes from a standing posture to a sitting posture, the buttocks are stressed, so that the first explosion bead 61 is broken to release the internal antibacterial and anti-inflammatory components;

The second explosion beads 62 are made of a super absorbent resin material, and it should be noted that in this embodiment, the second explosion beads 62 have high toughness and cannot be broken due to stress, a cavity, i.e., a heating layer, is provided in the second explosion beads 62, and the cavity contains a heating mixture synthesized by iron, vermiculite, activated carbon, inorganic salt and water, and the mixture can generate heat through iron oxidation, i.e., contact with oxygen begins to generate heat; it should be noted that, the second bursting beads in this embodiment do not affect the contact of the heating mixture with air, and should seal the vacuum package at the same time, avoid the heating mixture from losing efficacy when in use, and start heating when the package is torn off; therefore, the temperature of the bead-blasted sanitary towel 1 is increased in the using process, and the condition of dysmenorrhea of users can be relieved through the bead-blasted sanitary towel 1 with the increased temperature, so that the users can be helped to enter a sleep state more quickly; the antibacterial and anti-inflammatory component in the first pop-up beads 61 is mixed with the clove or lavender extract to emit fragrance when the mixture is heated, so that the pop-up beads sanitary towel 1 does not emit odor during the period of use.

The first bursting beads 61 are uniformly adhered and arranged in the first absorption core layer 41 along the length of the first absorption core layer 41, the uniformly adhered and arranged first bursting beads 61 can be used for resisting bacteria and diminishing inflammation more uniformly, the second bursting beads 62 are fixedly arranged in the second absorption core layer 42 in a diamond structure, and the water absorption at the middle position of the diamond structure is the largest, so that when the liquid is absorbed at the periphery of the second absorption core layer 42, part of the liquid at the periphery can be absorbed at the middle position, and the phenomenon that excessive absorption liquid is concentrated at the periphery edge positions to cause backflow and extravasation is avoided; when a user sleeps at night, because the user lies in a lying state, liquid can be preferentially contacted and adsorbed with the periphery of the bursting bead sanitary towel 1 under the action of gravity, and the second bursting bead 62 sanitary towel 1 adsorbs part of liquid at the positions with less periphery of the second bursting beads 62 to the middle position under the action of the second bursting beads 62 with more middle positions of the diamond structure, so that backflow or extravasation caused by excessive adsorption of the liquid at the periphery of the bursting bead sanitary towel 1 due to the lying posture during the sleeping state of the user at night is avoided.

The bead blasting sanitary towel 1 is in a back-shaped structure 7, the bead blasting sanitary towel 1 is divided into an inner side and an outer side, the inner side and the outer side of the bead blasting sanitary towel 1 are different in water absorption, namely the inner side bead blasting sanitary towel 1 is higher in water absorption than the outer side bead blasting sanitary towel 1, the inner side bead blasting sanitary towel 1 and the outer side bead blasting sanitary towel 1 are different in water absorption, so that a wetting gradient effect is formed, namely liquid in a region with small water absorption moves to a region with large water absorption; the user in the sleeping state at night can preferentially contact and adsorb the liquid with the periphery of the bursting bead sanitary towel 1 under the action of gravity because the user is in the lying state, so that the excessive absorption of the periphery is easy to generate liquid reflux and extravasation, and the water absorption of the inner bursting bead sanitary towel 1 is larger than that of the outer bursting bead sanitary towel 1, so that the liquid at the periphery edge position is adsorbed inwards, and the reflux or extravasation generated by the local excessive absorption of the liquid by the bursting bead sanitary towel 1 in the sleeping state is avoided.

In the use process, a user who is at night and is ready to enter a sleep state breaks the first bursting beads 61 one by hand after unpacking the package, then the user adheres the bottom surface of the bursting bead sanitary towel 1 to the surface of underpants, and after breaking the first bursting beads 61, the solid antibacterial and anti-inflammatory components in the first bursting beads 61 release and adhere to the first absorption core layer 41, so that bacteria and fungus microorganisms in the bursting bead sanitary towel 1 are continuously killed;

when a user at night and ready to enter a sleep state is in a lying posture, liquid preferentially flows downwards to the surrounding positions of the bursting bead sanitary towel 1 to contact and absorb under the action of gravity, the whole structure of the bursting bead sanitary towel 1 is in a reverse-shaped structure 7, the water absorption of the inner bursting bead sanitary towel 1 is greater than that of the outer bursting bead sanitary towel 1, namely, the liquid in a region with small moisture gradient effect and water absorption moves to a region with large water absorption; the liquid can be preferentially contacted and adsorbed with the peripheral positions of the bursting bead sanitary towel 1 under the action of gravity, and the water absorption of the inner bursting bead sanitary towel 1 is greater than that of the outer bursting bead sanitary towel 1, so that the liquid at the peripheral positions is adsorbed to the middle position, and the phenomenon that the liquid flows back or is leaked out due to the fact that the liquid is concentrated and cannot be timely absorbed and diffused at the peripheral positions of the bursting bead sanitary towel 1 under the lying posture is avoided;

after the first absorbent core layer 41 absorbs liquid, the liquid moves from the inside of the first absorbent core layer 41 to the inside of the second absorbent core layer 42 by the differential capillary effect of the first absorbent core layer 41 and the second absorbent core layer 42, thereby improving the water absorption of the bead-bursting sanitary napkin 1 and preventing the liquid from flowing back and leaking out; while the second absorbent core layer 42 absorbs liquid, the second bursting beads 62 fixedly adhered in the second absorbent core layer 42 are in a diamond structure, because a user is in a lying state, the liquid can be preferentially contacted and adsorbed with the periphery of the bursting bead sanitary towel 1 under the action of gravity, and the second bursting beads 62 sanitary towel 1 adsorbs part of liquid at the positions with less periphery of the second bursting beads 62 to the middle position under the action of the second bursting beads 62 with more middle positions of the diamond structure, so that backflow or extravasation caused by excessive adsorption of liquid at the periphery of the bursting bead sanitary towel 1 due to the lying posture is avoided when the user is in a sleeping state at night; the use is completed after the bursting bead sanitary towel 1 is full of absorbing liquid, so that the bursting bead sanitary towel 1 is used, and then a user removes and replaces the bursting bead sanitary towel 1.

The embodiment is suitable for the user at night and ready to enter the sleep state, because the user at night and ready to enter the sleep state is in a lying state, the liquid preferentially flows downwards to contact the surrounding positions of the bead-blasting sanitary towel 1 under the action of gravity; in the embodiment, the bursting bead sanitary towel 1 with the back-shaped structure 7, namely the inner bursting bead sanitary towel 1 has higher water absorption than the outer bursting bead sanitary towel 1 to form a wetting gradient effect, so that the situation that excessive absorption at the peripheral positions of users at night cannot be timely diffused to the middle position is avoided, and liquid backflow and extravasation in the bursting bead sanitary towel 1 are avoided; the user in the night active state, i.e. lying state, can adhere to the first absorbent core layer 41 after the first explosion beads 61 are broken, so that downward diffusion due to gravity is avoided, and the antibacterial and anti-inflammatory effects can be uniformly carried out;

in this embodiment, when the user in the lying state is also fixed and bonded with the second bursting beads 62 having the diamond structure, because the user is in the lying state, the liquid will be preferentially contacted and adsorbed with the periphery of the bursting bead sanitary towel 1 under the action of gravity, and the second bursting bead 62 sanitary towel 1 adsorbs part of the liquid at the positions where the periphery of the second bursting beads 62 are less to the middle position under the action of the second bursting beads 62 having more middle positions of the diamond structure, so that backflow or extravasation caused by excessive adsorption of the liquid at the periphery of the bursting bead sanitary towel 1 due to the lying posture during the sleeping state of the user at night is avoided; and the heating layer arranged in the second bursting beads 62 can increase the temperature of the bursting bead sanitary towel 1, thereby relieving the dysmenorrhea condition of users and helping the users to sleep faster; the present embodiment is therefore more suitable for use by persons at night and ready to enter a sleep state.

Example 5: on the basis of embodiment 4 of the present invention, as shown in fig. 8 to 9, this embodiment is suitable for a user at night and ready to go to sleep, i.e., is suitable for making a night type pop-up sanitary napkin 1.

Corresponding circular grooves 44 are formed in the bottom of the first absorption core layer 41 and the top of the second absorption core layer 42, a plurality of second explosion beads 62 are movably mounted in the circular grooves 44, the bottom of the first absorption core layer 41 is fixedly adhered to the top of the second absorption core layer 42, so that a closed cavity is formed by the corresponding circular grooves 44, a plurality of second explosion beads 62 are placed in the closed cavity, and the second explosion beads 62 can freely move in the closed cavity; the second bursting beads 62 freely moving in the closed chamber between the first and second absorbent core layers 41, 42 can increase the water absorption at different positions, i.e. can increase the water absorption in a movable manner;

when a user is in a sleeping state at night, when the contact position of liquid and the bursting bead sanitary towel 1 is changed due to the difference of the posture change and personal habit of the user, the liquid moves downwards under the action of gravity to be in contact with the bursting bead sanitary towel 1, and meanwhile, the second bursting beads 62 are consistent with the liquid moving direction under the action of gravity, so that the water absorption performance can be always increased at the position where the liquid is in concentrated contact and absorption when the contact position of the liquid and the bursting bead sanitary towel 1 is changed, and the liquid backflow or the exosmosis caused by the fact that the local liquid flow is too large to be absorbed in time when the contact position is changed due to the posture change or the habit difference of the user is avoided; for example, after the local first absorbent core layer 41 and the second absorbent core layer 42 are gradually saturated, or the first absorbent core layer 41 and the second absorbent core layer 42 cannot timely absorb all the liquid, the second bursting beads 62 move to the position to increase the water absorption and the contact area, so as to avoid the backflow or the extravasation of the liquid; the combined area of the plurality of second beads 62 in the closed chamber is about half of the closed chamber.

After the first absorbent core layer 41 absorbs liquid, the liquid moves from the inside of the first absorbent core layer 41 to the inside of the second absorbent core layer 42 by the differential capillary effect of the first absorbent core layer 41 and the second absorbent core layer 42, thereby improving the water absorption of the bead-bursting sanitary napkin 1 and preventing the liquid from flowing back and leaking out; the second bursting beads 62 which are freely moved in the closed cavity between the first absorption core layer 41 and the second absorption core layer 42 are consistent with the movement direction of the liquid under the action of gravity while the second absorption core layer 42 absorbs the liquid, so that the water absorption can be always increased at the position where the liquid is intensively contacted and absorbed when the contact position of the liquid and the bursting bead sanitary towel 1 is changed, and the liquid backflow or the exosmosis caused by overlarge local liquid flow and incapability of timely absorbing when the contact position is changed due to the change of the posture or the habit difference of a user is avoided;

during use, the heating mixture contained in the cavity arranged in the second bursting beads 62 heats, so that the temperature of the bursting bead sanitary towel 1 is increased during use to relieve the dysmenorrhea of users; the use is completed after the bursting bead sanitary towel 1 is full of absorbing liquid, so that the bursting bead sanitary towel 1 is used, and then a user removes and replaces the bursting bead sanitary towel 1.

The embodiment is suitable for users in night and ready to enter a sleep state, because the users in night and ready to enter the sleep state are in a lying state, liquid preferentially flows downwards to contact the positions around the bead-blasting sanitary towel 1 under the action of gravity, and the users can unconsciously roll irregularly in the sleep state, so that the contact and absorption positions of the liquid and the bead-blasting sanitary towel 1 are irregularly changed; therefore, the sealed cavity of the cylindrical structure is formed by bonding the grooves of the circular structure, the movable second bursting beads 62 in the sealed cavity of the cylindrical structure can move according to the change of the activity state of a user, and meanwhile, the movable second bursting beads 62 can be consistent with the change direction of the liquid under the action of gravity, so that the water absorption of the concentrated absorption position of the converted liquid is increased, and the situation that the bursting beads of the sanitary towel 1 are subjected to liquid backflow or extravasation when the user rolls frequently is prevented; therefore, the embodiment is suitable for users in the night state, and is particularly suitable for users in the night state and performing irregular rolling.

The present invention is described in the above embodiments, but the structure, arrangement relation and connection relation of each component of the present invention can be changed correspondingly.
