FIG. 13 is a perspective view of the bottom lid 60 in the first state as seen obliquely from above.
FIG. 14 is a perspective view of the bottom lid 60 in the first state as viewed obliquely from below.
FIG. 15 is a partially sectioned front view of the bottom lid 60 in the first state.
The bottom cover 60 is a substantially rectangular member having a shape capable of closing the opening 10a of the main body 10, and is formed of an integrally molded resin product. An outer peripheral edge fitting portion 62 for fitting the bottom lid 60 into the opening 10 a of the main body 10 is arranged on the outer peripheral edge portion 61 of the bottom lid 60 .
The outer peripheral edge fitting portion 62 of the bottom lid 60 has a fitting groove 63 into which the end edge portion 12b of the side plate 12 of the main body 10 forming the lower opening 10a of the main body 10 is fitted, and a fitting groove 63 into which the bottom lid 60 is fitted in plan view. Also included is a mating projection 64 that rises upwardly within body 10 adjacent the inside of groove 63 . With this configuration, the outer peripheral edge fitting portion 62 surrounds the flat plate portion 65 and is disposed on the outer peripheral portion of the bottom lid 60, so that the edge portion 12b of the opening portion 10a is positioned between the inner wall side and the outer wall side of the main body 10. are clamped and fitted from both sides.
In the illustrated example, the fitting grooves 63 are arranged continuously along the outer peripheral edge of the bottom lid 60 , but the fitting grooves 63 can also be intermittently arranged along the outer peripheral edge of the bottom lid 60 .

The fitting protrusion 64 is provided along the inner wall of the main body 10 continuously from a portion of the outer peripheral edge fitting portion 62 that abuts on the inner wall of the main body 10 . and is fitted with the inner wall of the main body 10 .
Also, the fitting protrusion 64 is provided in a substantially rectangular shape corresponding to the shape of the opening 10a on the lower side of the main body 10. As shown in FIG. At the four corners of the fitting protrusion 64, there are provided low protruding portions 64a protruding from the flat plate portion 65 toward the inside of the main body 10 at a second height h2 lower than the first height h1. It is

Also, the bottom lid 60 can be transformed from the first state shown in FIGS. 13 to 15 to a second state in which the central projecting portion 601 is lifted up toward the inside of the main body. The second state and the configuration associated with this second state will be described later.

The main body 10 and the opening/closing lid 20 described above are both obtained by injection molding using polypropylene (PP). good too. Linear low-density polyethylene (LLDPE) is preferably used for the bottom lid 60, and silicon rubber is used for the plate rubber 40. As shown in FIG. The fixed portion 41 is made of polypropylene (PP).

FIG. 16 is a side sectional view showing the airtight bag 100 containing the wet tissue 101. FIG.
As shown in FIG. 16( a ), wet tissues 101 are folded and stacked in a sealed bag 100 made of a flexible sheet, and sealed by the sealed bag 100 . Each wet tissue 101 is folded substantially in two to form a folded portion 102, and the folded portions 102 of each wet tissue 101 are alternately replaced. The lower half 101b of the wet tissue 101 folded in half is inserted between the upper half 101a of the wet tissue 101 positioned below and the upper half 101a of the wet tissue 101 positioned further down. Therefore, when the wet tissues 101 are picked up one by one and taken out, the lower half 101b of the taken out wet tissue 101 pulls up the upper half 101a of the wet tissue 101 positioned below. Note that the wet tissue 101 may be folded in a layered manner so that it can be taken out continuously, and is not particularly limited. For example, the folding method shown in FIG. good too. An opening 100a is provided at the upper end of the airtight bag 100, and the opening 100a is sealed by a lid piece 105 detachably attached to the upper surface of the airtight bag 100. As shown in FIG.

As the material of the wet tissue 101, for example, non-woven fabric, paper, fibrous material such as gauze, sheet-like foam, or paper-based soft material is used. As the liquid with which the wet tissue 101 is impregnated, a wetting agent containing a disinfectant, a disinfectant, a detergent, or the like, or cosmetics such as lotion or milky lotion can be considered. In the present embodiment, the sealing property between the main body 10 and the opening/closing lid 20 is enhanced, so wet wipes 101 impregnated with a highly volatile liquid such as alcohol can be preferably used. In this embodiment, the wet tissue 101 is impregnated with alcohol.

Next, a characteristic point of this embodiment configured as described above will be described. FIG. 17 is shown to facilitate understanding of the following description.
FIG. 17 is a partially enlarged cross-sectional view showing an enlarged upper portion of FIG. 8 and a correspondingly enlarged view of the packing member 30. As shown in FIG.

(Length of lower rib 31)
When using the wet tissue 101 , the user first presses the top plate portion 51 of the operation member 50 . As a result, the engagement between the locking piece 21 and the claw portion 52 is released. In this case, the opening/closing lid 20 is opened by the restoring force of the plate rubber 40 .

That is, the opening/closing lid 20 is biased by the plate rubber 40 and pivots about the swing shaft 24 in the opening direction (clockwise direction in FIGS. 8 and 17). After that, when the opening/closing lid 20 reaches the fully open position, the proximal end 20a of the opening/closing lid 20 comes into contact with the main body 10 and the opening/closing lid 20 stops.

Next, the wet tissue 101 is picked up with fingers from the outlet 15 of the main body 10 and pulled upward for use.

After the wet tissue 101 is taken out in this manner, the opening/closing lid 20 is closed. At this time, when the user manually pushes down the opening/closing lid 20, the opening/closing lid 20 is moved in the closing direction (counterclockwise in FIGS. 8 and 17) about the swing shaft 24 against the biasing force of the plate rubber 40. direction). After that, when the opening/closing lid 20 reaches the fully closed position, the locking piece 21 of the opening/closing lid 20 is engaged with the claw portion 52 of the operating member 50, and the opening/closing lid 20 is fixed at the fully closed position.

During this time, the lower rib 31 of the packing member 30 rises along the inclined surface 14a of the annular rib 14, as shown in FIG. That is, as described above, the packing member 30 is made of an elastic material, and the packing outer peripheral portion 30b and the lower rib 31 are integrated and elastically movable in the vertical direction. Therefore, when the opening/closing lid 20 is closed, when the lower rib 31 abuts against the inclined surface 14a of the annular rib 14, the outer circumferential portion 30b of the packing deforms upward, and the contact position of the lower rib 31 against the inclined surface 14a is increased. , relative to the packing member 30 . In this case, since the lower rib 31 is pressed against the inclined surface 14a by the restoring force of the packing outer peripheral portion 30b, the lower rib 31 and the inclined surface 14a are in close contact with each other. In this manner, the packing member 30 seals the outlet 15 of the main body 10 .

Here, if all of the lower ribs 31 of the packing member 30 are configured to be sufficiently long, the repulsion by the elastic body of the packing member 30 is large, so the operating force for closing the open/close lid 20 is increased, and it may be difficult to close. There is In addition, since the repulsion by the elastic body of the packing member 30 is large, the lower rib 31 and the periphery of the outlet 15 bite into each other at the abutting portion, and only the urging force urging the opening/closing lid 20 in the opening direction is applied. It may not open.
Therefore, in the present embodiment, the length of downward protrusion of the lower rib (adhesion portion) 31 gradually changes so that the side closer to the swing shaft 24 is longer than the side farther from the swing shaft 24 . It was configured. Specifically, as shown in FIG. 17(b), the position where the lower rib 31 protrudes most on the side closest to the pivot shaft 24 and the position where it protrudes least on the side farthest from the pivot shaft 24 The height difference dh at the tip position is 1.6 mm.

The portion of the lower rib 31 closer to the swing shaft 24 is in close contact with the inclined surface 14 a and the flat surface of the recess 13 , and the downward protrusion length of the lower rib 31 increases as the distance from the swing shaft 24 increases. By gradually shortening the length, it is brought into close contact only with the inclined surface 14a.
At the portion farthest from the swing shaft 24, which is the portion that can be reliably held down by the operating member 50, the downward protrusion length of the lower rib 31 is the shortest, and only the inclined surface 14a is in close contact. As a result, when the operation member 50 is pushed in and the engagement between the operation member 50 and the opening/closing lid 20 is released, the opening/closing lid 20 can be easily opened only by the biasing force of the plate rubber 40 .
Conversely, on the side closer to the swing shaft 24, the airtightness is enhanced by tightly contacting the inclined surface 14a to the flat surface of the recess 13. As shown in FIG.

It is desirable that the height difference dh of the tip position is 1 mm or more in order to ensure the tightness of the wet tissue container 1 . In addition, it is desirable that the height difference dh of the tip position is 2.5 mm or less so that the opening and closing lid 20 can be easily opened and closed.

In this embodiment, the height difference dh is 1.6 mm as described above, so that the opening and closing lid 20 can be easily opened and closed while ensuring the tightness of the wet tissue container 1 .
Further, in this embodiment, the lower rib 31 contacts the inclined surface 14 a of the annular rib 14 . Therefore, the force with which the lower rib 31 contacts the inclined surface 14a is weakened, and the force required to close the opening/closing lid 20 can be reduced. Also, the lower rib 31 can be prevented from sticking to the inclined surface 14a, and the opening/closing lid 20 can be easily opened.

(Distance between peripheral portion of outlet 15 and packing member 30)
In addition, in the conventional wet tissue container, if the wet tissue is not properly pushed back into the outlet when the opening/closing lid is closed, the wet tissue is caught between the peripheral edge of the outlet and the abutting portion on the side of the opening/closing lid. I was afraid. In this case, the opening/closing lid may not be closed to a predetermined position, or the opening/closing lid and the main body may be bent, and the wet tissue container may not be sufficiently sealed. .
Therefore, in the wet tissue container 1 of the present embodiment, when the opening/closing lid 20 is in the closed position, the minimum distance S (see FIG. 17) between the edge rib 15a at the peripheral edge of the outlet 15 and the packing member 30 is 0.3 mm or more. are spaced apart. The minimum distance S of 0.3 mm is equivalent to the thickness of one wet tissue 101 of 0.3 mm. Therefore, even if the remaining wet tissue protruding from the outlet 15 is caught between the peripheral edge of the outlet 15 and the packing member 30, the wet tissue container 1 can be sufficiently sealed.
In addition, it is preferable that the minimum distance S is 1.5 mm or less from the viewpoint of preventing the wet tissue container from drying out, since unnecessary space can be reduced.

In this embodiment, in the closed position of the opening/closing lid 20, the minimum distance S between the edge rib 15a of the peripheral portion of the outlet 15 and the packing member 30 is set to 0.2 mm or more at all positions. . However, the wet tissue 101 is often drawn out toward the front side of the wet tissue container 1, that is, toward the pivot shaft 24. As shown in FIG. In addition, since the opening/closing lid 20 rotates around the pivot shaft 24, when the opening/closing lid 20 is closed, the wet tissue 101 coming out of the outlet 15 is pushed forward (farther from the pivot shaft 24). Therefore, when the open/close lid 20 is in the closed position, if the minimum distance between the packing member 30 and at least the half circumference of the outlet 15 farther from the pivot shaft 24 is 0.3 mm or more, the outer edge of the outlet 15 It is possible to prevent the wet tissue from being strongly bitten between the opening and closing lid side and the contact portion on the opening/closing lid side.

(Prevention of fall of operation member 50)
Further, in the wet tissue container 1 of the present embodiment, the operating member 50 is provided so that the opening/closing lid 20 can be opened with one hand. As described above, the operating member 50 is urged by the spring portion 56 toward the restricting position (indicated by solid lines in FIG. 17). (represented by a dotted chain line).

In the wet tissue container 1 of the present embodiment, the end portion of the operation member 50 on the open/close lid 20 side is arranged to face the free end 20e of the open/close lid 20 as shown in FIG. Therefore, the main body 10 cannot be configured to regulate the position of the operating member 50 at the end of the operating member 50 on the open/close lid 20 side. If a structure for regulating the position of the operating member 50 is not provided, the operating member 50 will fall over the regulated position in the clockwise direction in FIG. I'll put it away.

Therefore, in the present embodiment, the main body 10 is provided with the main body protrusion 17b which is located at a position hidden by the operation member 50 and protrudes upward from the bottom plate 17a. Further, the operation member 50 is provided with an operation member protrusion 57 that protrudes downward at a position hidden by the operation member 50 when viewed from the upper surface side on the back side of the top plate portion 51 . When the opening/closing cover 20 is open, the operating member protrusion 57 abuts against the main body protrusion 17b, thereby restricting the movement of the operating member 50 toward the restricted position. It is prevented from falling over beyond the regulation position.

(Lifting up of bottom cover 60)
In addition, the wet tissue container 1 of the present embodiment has a configuration capable of accommodating a larger number of wet tissues 101 (for example, about 100 sheets) than conventional ones. Therefore, the length of the side plate 12 of the main body 10 (height of the main body 10) is longer than conventional.
Even with a conventional wet tissue container, it is sometimes difficult to take out the wet tissue when the remaining amount of the stored wet tissue is low. In particular, if the wet tissue returns to the inside of the container when the open/close lid is closed with a small amount of wet tissue remaining, insert your finger through the outlet to the bottom of the container to remove the wet tissue. It was necessary to pick up the tissue, which sometimes made it difficult to use.
Furthermore, since the wet tissue container 1 of the present embodiment can accommodate a larger number of wet tissues 101 than the conventional one, the depth from the outlet 15 to the bottom of the container is deep, and the same as the conventional one. In the configuration, it is expected that it will be difficult to take out wet wipes when the remaining amount is low.

Therefore, the bottom lid 60 of the present embodiment can be transformed from the first state shown in FIGS. 13 to 15 to a second state in which the central protruding portion 601 is lifted up toward the inside of the main body.
FIG. 18 is a perspective view of the bottom lid 60 in the second state as viewed obliquely from above.
FIG. 19 is a diagram showing cross sections of the bottom lid 60 side by side in the first state and the second state. FIG. 19(a) is a cross-sectional view of the bottom cover in the first state cut at the position of arrows EE in FIG. 13, and FIG. 19(b) is the position of arrows FF in FIG. FIG. 10 is a cross-sectional view of the bottom lid in the second state taken at .

The bottom lid 60 has an extendable portion 600 near the center of the bottom lid 60 to enable deformation between the first state and the second state.
The flat plate portion 65 is a flat portion provided around the elastic portion 600 .

The expandable portion 600 is provided substantially in the center of the flat plate portion 65 and protrudes inwardly of the main body 10 from a first state in which it protrudes inwardly of the main body 10 to a first height hs1 (see FIG. 19(a)). It is configured to be deformable to a second state protruded to a second height hs2 (see FIG. 19(b)) higher than the first height. The first height hs1 and the second height hs2 both extend from the surface of the flat plate portion 65 (surface on the inner side of the main body 10) to the surface of the planar portion 601a (inner surface of the main body 10). surface).
More specifically, the expansion/contraction portion 600 includes a central protruding portion 601 having a substantially circular shape when viewed from above, a central wall portion 602, a central flat surface 603, a first peripheral wall portion 604, and a second peripheral wall. 605.

The center protruding portion 601 protrudes inward (upward in FIG. 19) of the main body 10, and includes a planar portion 601a having a curved surface and a plurality of rib portions 601b radially arranged from the planar portion 601a. have. Note that the planar portion 601a may be a flat surface instead of a curved surface. By configuring the center protruding portion 601 by combining the planar portion 601a and the rib portion 601b, sufficient strength can be ensured without increasing the thickness of the center protruding portion 601. FIG. In addition, the area supporting the airtight bag 100 (wet tissue 101) can be enlarged, and the airtight bag 100 (wet tissue 101) can be stably supported particularly in the second state described later.

The central wall portion 602 is connected to the outer peripheral edge of the central protruding portion 601 so as to surround the central protruding portion 601 and extends vertically (substantially vertically).

The central flat surface 603 is connected to the central wall portion 602 so as to surround the central wall portion 602 and is configured as a surface substantially parallel to the flat plate portion 65 . Also, on the outer side of the main body 10 (lower side in FIG. 19), the central flat surface 603 is substantially flush with the lowermost portion of the outer edge of the bottom lid. This configuration can improve the stability when the wet tissue container 1 is placed. Even if the central flat surface 603 is substantially flush with the flat plate portion 65, the same effect can be obtained.
In addition, by providing the central flat surface 603 and the rib portion 601b, it is possible to ensure the strength when deformed to the second state, and the wet tissue 101 can Even in a state where the amount of liquid impregnated in the wet tissue 101 is large, the weight of the wet tissue 101 does not cause the wet tissue 101 to return to the first shape.
Furthermore, by providing the central flat surface 603 and the rib portion 601b, the strength of the wet tissue container 1 does not easily decrease even after repeated use, and the durability of the wet tissue container 1 can be enhanced.

The central protruding portion 601, the central wall portion 602, and the central flat surface 603 are portions that move integrally with little deformation in both the first state and the second state. Also referred to as central portion 610 .
The central portion 610 is pressed by a finger or the like when the expansion/contraction portion 600 is deformed from the first state to the second state, and vice versa.

The first peripheral wall portion 604 is configured in a ring shape surrounding the central portion 610. In the first state, the end (inner edge) of the first peripheral wall portion 604 on the side of the central portion 610 is the opposite end. It is a sloping surface that is inclined to be lower (closer to the outer side of the main body 10 ) than the portion (outer edge), and connects between the central flat surface 603 and the second peripheral wall portion 605 . That is, in the first state, the first peripheral wall portion 604 has a shape corresponding to the inner surface shape of a truncated cone in which the end portion (inner edge) on the central portion 610 side is the smaller diameter side.
In addition, in the second state, the first peripheral wall portion 604 has an end (inner edge) on the center portion 610 side higher than the opposite end (outer edge) (main body 10 , and connects between the central flat surface 603 and the second peripheral wall 605 . That is, in the second state, the first peripheral wall portion 604 has a shape corresponding to the outer surface shape of a truncated cone in which the end portion (inner edge) on the central portion 610 side is the smaller diameter side.

The second peripheral wall portion 605 surrounds the first peripheral wall portion 604 and is connected to the peripheral edge portion of the first peripheral wall portion 604 on the inner side of the main body 10 and the flat plate portion 65 in the first state.

Here, a method for deforming the elastic part 600 configured as described above between the first state and the second state will be described. When deforming the expandable portion 600 from the first state to the second state, the bottom lid 60 may be attached to the main body 10, or the bottom lid 60 may be removed from the main body 10. you can go When deforming the expandable portion 600 from the second state to the first state, the bottom cover 60 is removed from the main body 10 .

First, when deforming the expandable portion 600 from the first state shown in FIG. 19A to the second state shown in FIG. 19B, the expandable portion 600 is A pressing force is applied with a finger or the like in the direction of the arrow shown in FIG. The pressing force applied to the center portion 610 pushes up the center portion 610 (the center projection portion 601, the center wall portion 602, and the center flat surface 603) and the first peripheral wall portion 604 toward the inside of the main body 10. and transforms into a second state. In this second state, as shown in FIG. 19B, the connecting portion between the center flat surface 603 and the first peripheral wall portion 604 and the connection portion between the first peripheral wall portion 604 and the second peripheral wall portion 605 The first peripheral wall portion 604 is turned upside down with the connection portion as a fulcrum. That is, the connecting portion between the central flat surface 603 and the first peripheral wall portion 604 is lifted toward the inside of the main body 10 .
By pushing up the central part 610 inwardly of the main body 10 in this way, as shown in FIG. be able to. After being deformed, the stretchable portion 600 does not naturally return to the first state and is maintained in the second state.

Next, when deforming the expandable portion 600 from the second state shown in FIG. 19B to the first state shown in FIG. Then, a pressing force is applied in the direction of the arrow shown in FIG. 19(b) by hand or the like. The pressing force applied to the central portion 610 pushes down the central portion 610 (the central protruding portion 601, the central wall portion 602, and the central flat surface 603) and the first peripheral wall portion 604 to deform to the first state. do. In this first state, as shown in FIG. 19A, the connecting portion between the center flat surface 603 and the first peripheral wall portion 604 and the connection portion between the first peripheral wall portion 604 and the second peripheral wall portion 605 are separated. The first peripheral wall portion 604 is again inverted with the connection portion as a fulcrum. By pushing down the central portion 610 in this way, the expandable portion 600 can be contracted and returned to the first state of protruding to the first height, as shown in FIG. 19(a).

Here, the first peripheral wall portion 604 is preferably formed thinner than the central flat surface 603 in order to facilitate deformation of the expandable portion 600 and to make the central portion 610 difficult to deform. As an example, the central flat surface 603 has a thickness of 1 mm to 2 mm, and the first peripheral wall 604 has a thickness of 0.5 mm to 1 mm. The thicknesses of the planar portion 601a, the central wall portion 602, and the second peripheral wall portion 605 are not particularly limited as long as the respective shapes can be maintained.

According to the wet tissue container 1 of this embodiment, by extending the extendable portion 600 provided in the bottom lid 60 to the second state, the bottom can be raised as shown in FIG. The tissue 101 can be easily taken out. In addition, when the wet tissues 101 in the main body 10 are used up, a large number of new sealed bags 100 (wet tissues 101) can be replenished by contracting the expandable part 600 again to the first state.

Further, the bottom lid 60 has no cuts or openings, and the expandable portion 600 can be transformed between the first state and the second state without impairing the sealing performance of the bottom lid 60 . Therefore, the wet tissue container 1 of the present embodiment can maintain the sealed state regardless of the deformed state of the expandable portion 600 .

In addition, in the present embodiment, the central protrusion 601 and the central portion 610 that constitute the expandable portion 600 are substantially circular, and the first peripheral wall portion 604 and the second peripheral wall portion 605 are formed as the central protruding portion 601 and the central portion 610. Although they are concentric circles, the shapes of the center protruding portion 601 and center portion 610, the first peripheral wall portion 604, and the second peripheral wall portion 605 may be other than concentric circles.

(Low protrusion 64a)
In addition, in the wet tissue container 1 of the present embodiment, the fitting protrusion 64 of the bottom lid 60 is deeply inserted into the main body 10 for fitting, thereby improving the sealing performance of the wet tissue container 1 . In such a form, the higher the height of the fitting projection 64 (the amount of protrusion inward of the main body 10), the better the sealing performance can be expected. That is, since the bottom lid 60 is made of an elastic resin, the rigidity of the bottom lid 60 can be increased by increasing the height of the fitting protrusion, and the effect of suppressing deformation of the bottom lid 60 can be obtained. , can contribute to an improvement in sealing performance.
However, increasing the height of the fitting protrusion may make it difficult to open the bottom cover.

Therefore, in the wet tissue container 1 of the present embodiment, the four corners of the fitting projections 64 of the bottom lid 60 project from the flat plate portion 65 toward the inside of the main body 10 at a height lower than the first height h1. A low protruding portion 64a protruding at a second height h2 is provided. Specifically, the first height h1 shown in FIG. 15 was set to 12.8 mm, and the second height h2 was set to 9.2 mm. At one of the four corners of the bottom cover 60, a hooking piece 60a protruding outward is provided. As a result, when removing the bottom cover 60 from the main body 10, it is more likely to be removed from the corner where the hooking piece 60a is provided. Low protrusions 64a are provided at the four corners of the bottom lid 60, and the fitting amount (fitting depth) between the main body 10 and the low protrusions 64a is small. Easy to start removing. If the bottom cover 60 can be removed from the main body 10 to some extent, the subsequent removal work can be performed relatively easily. Therefore, the work of removing the bottom cover 60 from the main body 10 can be easily performed by providing the low projecting portion 64a.

Here, it is desirable that the second height h2 is 10 mm or less in order to facilitate the work of removing the bottom cover 60 from the main body 10. As shown in FIG.
In addition, it is desirable that the second height h2 is 5 mm or more in order to secure the rigidity of the four corners of the bottom lid 60 and prevent the sealing performance from deteriorating.
Furthermore, it is desirable that the range L (see FIGS. 13 and 15) in which the low protruding portion 64a is provided is 5 mm or more in order to facilitate the work of removing the bottom cover 60 from the main body 10. FIG.
Furthermore, it is desirable that the range L in which the low protruding portion 64a is provided is within 25 mm in order to secure the rigidity of the four corners of the bottom lid 60 and prevent the sealing performance from deteriorating.
13 and 15, the dimension of the range L is the height of the second height h2 starting from the center position of the top of the low protruding portion 64a provided on the other side that intersects at the corner. It is the dimension of the range that is

In addition, since the four corners of the bottom lid 60 are the positions where the sides in two orthogonal directions intersect, they are sites with higher rigidity than the vicinity of the center of the four sides of the bottom lid 60, and the low protruding portion 64a is provided. The reduction in rigidity at the four corners due to this does not adversely affect the tightness.
The low protruding portion 64a may be provided at least one of the four corners, not at all the four corners as in the present embodiment. For example, the low protruding portion 64a may be provided only at the corner where the hooking piece 60a is provided.

Further, the fitting projection 64 has a belt-like protrusion 64b that continuously protrudes toward the inner wall of the main body 10 over the entire circumference of the wall surface that abuts on the inner wall of the main body. The belt-shaped convex portion 64b is also continuously provided on the wall surface of the low protruding portion 64a.
If the outer wall surface of the fitting projection 64 and the inner wall surface of the main body 10 are fitted without providing the strip-shaped convex portion 64b, the contact area is large, so a large force is required to remove and attach the bottom cover 60. is required, making the removal work difficult. On the other hand, in the wet tissue container 1 of the present embodiment, since the strip-shaped convex portion 64b is provided, the contact area between the bottom lid 60 and the main body 10 is reduced, and the bottom lid 60 can be removed more easily.
