Description

PACKAGING AND TAKING DEVICE BY

PIPETTE LAYER OF 2 MIXTURES TO BE MOUNTED ON THE NECK OF A BOTTLE

The invention relates to a device for packaging and sampling by metering pipette of 2 products to be mixed. This device is in practice intended to be mounted on the neck of a bottle.

Document EP3053848A1 of the Applicant describes a device for packaging two products to be mixed comprising two parts respectively, a reservoir provided with a compartment whose bottom has a membrane and a striker cap mounted on the reservoir and intended to strike the membrane by translation vertical. In practice, the cap / tank assembly is screwed onto the bottle by means of a thread. In addition, the cover drives the reservoir on the neck of the bottle by means of fins present both on the reservoir and the cover which allow rotation in the direction of screwing but not in that of unscrewing. It is therefore in practice impossible to unscrew the device before percussion, thus preventing access to the bottle. The cover and the reservoir also have complementary means respectively arranged on the upper surface of the reservoir and the bottom of the cover allowing, after percussion, to separate the device from the bottle by unscrewing. The device thus designed does not provide access to the content by means of a dosing pipette. In addition, it does not have child safety in the sense that it is possible to access the contents of the bottle not simply unscrewing.

Document EP2687198A1, also from the Applicant, describes a packaging device allowing a sampling by metering pipette but in which the mixture of two products is not provided. This device does not have 2 parts but 3 parts respectively, a section reducer, an intermediate part mounted on the freewheel on the section reducer and provided with an orifice allowing access by a metering pipette and a cover. The cover and the intermediate piece are provided with lugs and complementary cams allowing, between two withdrawals, to prohibit access of the bottle to children by simple rotation of the cover on the intermediate piece.

The problem which the invention proposes to solve is that of developing a device which has at least two functions, that is the mixing of two substances within the same bottle and the taking of the mixture by metering pipette.

The objective is also that of developing a device advantageously having a third function which is that of child safety, that is to say prohibiting access to the bottle by simple unscrewing.

To do this, the Applicant has developed a packaging and sampling device using a metering pipette comprising four separate elements, respectively a reservoir, an intermediate piece, a striker and a cover.

All of these elements are arranged in such a way that there is advantageously no possible opening of the bottle before percussion, while respecting the sealing of the parts relative to each other.

More specifically, the subject of the invention is a device for packaging and sampling by metering pipette of 2 products to be mixed intended to be mounted on the neck of a bottle comprising:

- a tank room with:

o of a tank proper having a bottom, itself having a membrane intended to be struck, o of a skirt connecting said tank proper, whose external surface has a stopper and whose height advantageously corresponds to less at the height of the neck of the bottle than it is intended to cover, o,

- an intermediate piece / striker assembly mounted on the reservoir piece comprising:

o an intermediate piece mounted on the reservoir piece, bearing on the stopper, o a striker provided with an orifice for access to a metering pipette, said striker being mounted movable in translation on the intermediate piece,

- a cover mounted on the intermediate piece / striker assembly, in direct or indirect support on the stopper of the tank piece and having at its lower end a tamper-evident strip.

Of course, any connection means making it possible to secure the device to the neck of the bottle can be envisaged. Without limitation, it may for example be a screwing and / or a clipping, or even a bonding.

When the connection is made by screwing, the rotation of the device on the neck of the bottle can be obtained by various means.

It may for example be a bayonet system provided between the skirt of the reservoir piece and the neck of the bottle. In this case, the device is secured to the bottle by a vertical movement of translation and then of rotation.

Screwing can also be obtained by threading. More specifically, the skirt of the reservoir part has on its internal face a thread intended to cooperate with a corresponding thread from the outside of the neck, so as to allow the device to be screwed onto the bottle.

To prevent separation of the device from the neck of the bottle, the screwing is doubled by a clipping of the device on the neck of the bottle. To do this, the lower end of the skirt of the reservoir piece advantageously has a retaining ring intended to be inserted under the neck of the bottle by clipping.

In practice, the intermediate part is mounted exclusively on the reservoir part.

According to another characteristic of the invention, the attachment of the intermediate piece to the reservoir piece is carried out by simple clipping. To do this, the reservoir part and the intermediate part have complementary clipping means such as for example retaining rods. Thus, the outer wall of the skirt of the reservoir part has, on all or part of its periphery, a retaining ring positioned at a height such, relative to the stopper, that it comes to retain a retaining ring complementary arranged at the lower end and over all or part of the periphery of the intermediate piece.

Under these conditions, the intermediate part is made integral with the reservoir part definitively. The principle of clipping also causes a freewheeling phenomenon between the intermediate part and the reservoir part in one direction and in the other.

In the embodiment according to which the assembly of the reservoir part on the bottle is carried out by screwing, it is then necessary to provide means making it possible to drive the reservoir part in rotation on the bottle even when the intermediate part is clipped onto the tank part.

In an advantageous embodiment, the reservoir part can only be screwed and not unscrewed so as to prevent the separation of the reservoir part from the neck of the bottle.

To do this, the reservoir piece and the intermediate piece each have complementary drive means capable of causing the rotation of the intermediate piece / reservoir piece assembly on the neck of the bottle, only in the direction of screwing.

In an advantageous embodiment, the reservoir part comprises a crown connecting the reservoir proper to the skirt, the crown having an upper face provided with notches.

The intermediate piece is in turn provided with complementary blades emerging from its internal wall, directly opposite the notches of the crown connecting the actual tank with the skirt, the complementary blades being oriented so as to allow the rotation of the tank piece on the neck in the screwing direction by pressing on the notches of the crown of the reservoir piece.

According to another characteristic, the striker is in the form of a cylinder whose lower end, which is advantageously protruding and pointed, opens into the reservoir and whose upper end is provided with a wall having an orifice access to a metering pipette, advantageously central, the wall extending laterally by a skirt.

To avoid separation of the striker from the intermediate piece at the time of use, the striker skirt is provided with first locking means intended to cooperate with corresponding first means that the intermediate piece has, so as to allow the striker to be blocked in the direction of ascent, before percussion.

In practice, the locking means are in the form of 2 peripheral retaining rods arranged over all or part of the circumference respectively, from the upper end of the intermediate piece and from the lower end of the striker skirt.

To ensure that the striker does not rise after percussion at the time of removal, the intermediate piece has second locking means intended to cooperate with the first means that the skirt of the striker has. As before, it is in practice a peripheral retaining ring arranged on all or part of the circumference of the internal wall of the intermediate piece.

According to another characteristic, the intermediate piece and the cover have complementary drive means for causing the rotation, by the cover, in the closing direction, of the striker / intermediate piece assembly, itself causing the rotation of the reservoir part on the neck of the bottle, while authorizing the separation of the cover from the intermediate part for sampling by means of the dosing pipette.

In other words, the complementary means must make it possible both to screw the device onto the bottle but also to open the device to access the sampling orifice by means of the dosing pipette, that is to say separate the cover from the intermediate piece.

In practice, the complementary means of the cover are in the form of pins, pins or the like arranged on its internal face. The pins are evenly distributed on the internal face and their number will depend on the number of complementary means arranged on the intermediate piece.

Advantageously, each complementary means of the intermediate piece is in the form of a cam into which the lug is inserted, each cam having a first vertical portion at least in its lower part and whose lower end is extends by a second horizontal portion, the end of which, in the direction of unscrewing, itself extends by a third oblique opening portion facing upwards. Preferably, 4 lug / cam series are provided distributed over the entire circumference of the device.

According to the invention, each cam has a vertical portion at least in its lower part.

In a first embodiment, the first portion is vertical over its entire height.

In a second embodiment, to facilitate assembly of the cover on the intermediate piece, the first portion has two zones, respectively an upper zone and a vertical lower zone, the upper zone being flared, for example in the form of a funnel. to drive the lug on the hood into the lower vertical zone.

Advantageously, the upper and lower zones of the first portion of each cam are separated by a boss.

The upper zone of the first portion of the cams in combination with the lugs of the cover generate the rotation of the cover / intermediate piece / striker assembly on the reservoir piece in one direction and in particular in the direction of closing before percussion. Rotation in the direction of unscrewing, that is to say in the direction of opening is possible but without effect since the intermediate part is freewheeling on the reservoir part in the direction of opening.

The percussion of the tank membrane is obtained by vertical translation of the striker, once the tamper-evident strip has been removed. To do this, the user exerts pressure on the cover so that the pins travel from the upper zone of the first portion of the cams to the lower zone, until they come into abutment at the bottom of said lower zone.

According to another characteristic, the cover has blades with a spring effect capable of holding the lugs by pressing on the intermediate piece in a zone of height h, separating said boss from the second horizontal junction portion. This characteristic allows, once the percussion has been effected, to prohibit rotation in the direction of opening, without exerting any prior pressure on the cover. The device is thus secure and prohibits its access to children. In addition, the retention of the pins in the height zone h ensures the maintenance of the seal between the striker and the cover.

The opening is therefore effected by a first pressure movement which generates the translation of the pins in the lower zone of the first portion of the cam, then of rotation in the direction of the opening, which causes the displacement of the pins in the portion horizontal then in the oblique portion of the cam.

The invention and the advantages which ensue therefrom will emerge clearly from the embodiment which follows in support of the appended figures.

In Figure 1, there is shown the different elements of the packaging and sampling device of the invention.

This device, designated by the general reference (1), comprises a reservoir part (2), an intermediate part (3), a striker (4) and a cover (5). This device is intended to be made integral with the neck (6) of a bottle (7). As shown in Figures 1 to 3, the seal between the reservoir part (2) and the neck (6) of the bottle (7) is obtained by means of a flat seal (8) or any other equivalent means such as seal O-ring or sealing skirt.

The different parts will now be described in detail.

According to a first characteristic, the part (2) designated as reservoir part comprises a proper reservoir (9) connected by means of a crown (10) to a skirt (11). The internal face of the skirt (11) has a thread (12) intended to cooperate with the corresponding thread (6) of the neck of the bottle (7). The skirt (11) also has at its lower end, a retaining ring (13) intended to be inserted under the neck (41) of the bottle (7). This ring thus prohibits the removal of the reservoir part once it is screwed onto the neck of the bottle. The skirt (11) also has, on its outer wall, a stopper (14) arranged over its entire periphery. The skirt (11) also has, at an altitude higher than that of the stop (14), a retaining ring (15) intended to ensure the joining of the intermediate piece (3) on the reservoir piece (2 ). The crown (10) is provided on its upper surface and as shown in FIG. 5a, with a plurality of notches (16) constituting complementary means making it possible to ensure rotation in the direction of closing of the intermediate piece on the tank part.

The intermediate part (3) is intended to be mounted on the reservoir part (2). In the embodiment as illustrated, the mounting is obtained by clipping by means of a retaining ring (17) arranged at the lower end of the internal wall of the intermediate piece. The retaining ring (17) is thus intended to be caught under the retaining ring (15) corresponding to the reservoir part. The intermediate piece has a lower part (18a) and an upper part (18b) connected by a shoulder (19). The lower part (18a) is extended at its lower edge by a peripheral flange (20) intended to come to bear on the stopper (14) of the reservoir part after clipping. The intermediate piece (3) also has blades (21) intended to cooperate with the complementary notches (16) that the crown (10) of the reservoir piece (2) has (see Figure 5b). In its upper part (18b), the intermediate piece (3) has 2 peripheral retaining rods, respectively an upper rod (22) and a lower rod (23).

According to another characteristic, the intermediate part (3) is provided on its external lateral face, with cams (24). In practice, 4 cams (24) are regularly distributed on the external face of the skirt. Each Carmelite (24) has 3 portions respectively a first portion at least partially vertical (25), extending at its lower end by a second horizontal portion (26) then by an oblique opening portion (27) oriented upwards. . In the embodiment as it appears in particular in FIGS. 1 and 5b, the first portion (25) comprises 2 zones respectively an upper zone (25a) and a lower zone (25b), separated by a boss (28). In the following description, the height separating the boss from the horizontal junction portion (26) is defined by (h).

The striker (4) is in the form of a cylinder (29) opening into the tank (9). The cylinder has a projecting and pointed end and is further provided with an upper wall (30) provided with a central orifice (31), the upper wall (30) extending laterally by a skirt (32). As shown in Figures 2 and 3, the skirt (32) has at its lower end a retaining ring (33) intended to cooperate by clipping with the retaining ring (22) corresponding to the upper end of the intermediate piece ( 3).

The cover (5) comprises a bottom (34) provided with a central sealing pin (35) intended to come to cooperate with the orifice (31) of the striker. The cover (5) also has a side wall (36) in the form of an upper part (36a) and a lower part (36b) connected by a shoulder (36c). The lower part (36b) of the wall is provided with lugs (37) distributed over the entire circumference of the side wall. The number of pins (37) is equal to the number of cams (24), in this case 4. As shown in the figures, the shoulder (36c) is provided on its underside with elastic blades (38). Finally, the cover (5) has, at the lower end of the lower part (36b), a tamper-evident tab (39) intended to come to bear on the flange (20) before it is removed, that is to say before percussion.

In Figure 2, the device is shown in section before percussion. Under these conditions, the tamper-evident strip (39) has not yet been removed. It is supported on the edge (20) of the intermediate piece (3), which itself is supported on the stopper (14) of the reservoir piece (2). In this position, the retaining ring (33) of the skirt (32) of the striker is positioned in contact with and below the lip (22) of the upper part (18b) of the intermediate piece (3).

In Figure 3, the device is shown in section after percussion. Under these conditions, the tamper-evident strip (39) was removed. The hood / striker assembly is then moved in vertical translation by pressing the user on the hood (5). The striker cylinder (29) then strikes the membrane (40) of the reservoir (9). In the impacted position, in the absence of user support on the cover, the retaining ring (33) of the striker is taken below the retaining ring (23) of the intermediate piece (2) thus preventing ascent of the striker after percussion. Likewise, the elastic blades (38) present on the internal surface of the shoulder (36c) of the cover are in contact with the shoulder (19) of the intermediate piece (3). The spring effect of these blades means that the lugs (37) rise in the portion (25b) of the cam (25) and are then positioned in the lower region (25b) of the first portion and more precisely in the height region. h.

The device has 3 seals respectively:

- a seal between the reservoir part and the neck provided by the flat seal (8),

a seal between the striker and the reservoir piece provided by the contact between the wall of the reservoir (9) with that of the cylinder (29) of the striker,

- a seal between the cover and the reservoir part provided by the contact between the pin (35) and the orifice (31).

The operating principle of the device is shown in Figure 6.

In the illustrated embodiment, the reservoir part, the intermediate part, the striker and the cover are associated with each other, once the reservoir is filled, before securing the assembly to the neck of the bottle.

In another embodiment, the reservoir part is first fixed on the neck, the reservoir is filled with one of the two products of the mixture and then the cap / striker / intermediate part assembly is mounted on the reservoir part.

When all of the component parts of the device are assembled before mounting on the bottle, the first step of the process consists in screwing the device onto the bottle.

More specifically, the cover (5) is made to act on the intermediate piece (3) by means of the 4 pins (37) then positioned in the upper zone (25a) of the first portion (25) of the cam (24). The rotation in the screwing direction of the cover then effectively causes the rotation of the intermediate piece.

The screwing of the intermediate piece on the tank piece is obtained by means of the blades (21) which drive the corresponding notches (16) arranged on the crown (10) of the tank piece.

The screwing is thus continued until the retaining ring (13) comes to be caught under (41) the neck (6), marking the end of the tightening (FIG. 6a).

In the embodiment as shown, since the drive of the intermediate piece on the reservoir piece can only be done in one direction, that is to say in the direction of screwing, it becomes impossible to unscrew the device. Indeed, in the opposite direction to that of screwing, the cover drives the intermediate part, which is coasting, so that it rotates in a vacuum. There is therefore no possibility of accessing the contents of the bottle before percussion.

Figure 6b shows the position of the cover on the intermediate piece after removal of the strip and before percussion. At this time, the lugs (37) of the cover are always positioned in the upper zone (25a) of the vertical portion (25) of the cam (24).

To strike the membrane (40) of the tank, the user presses on the cover causing the striker to move in translation in the tank. The pins (37) then move vertically in the first portion (25) of the cam (24) in order to be housed in the horizontal junction portion (26), in line with the vertical portion (25). In this position, the protruding end of the striker tears the membrane (40). The percussion is effective. This position is shown in Figure 6c.

Once the percussion has been carried out, the elastic blades (38) exert their spring effect and raise the lugs of the cover in the zone (25b) of height h. The pins (37) then lock against the boss (28). It is therefore not possible to separate the cover from the intermediate piece without first pressing the cover vertically until the pins reach the horizontal junction portion. This system is therefore advantageous in that it prohibits any unexpected opening by a child by simple rotation of the cover in the direction of unscrewing. In addition, the boss (28) prohibits the raising of the cover (5) beyond the height (h), thereby ensuring that the device remains watertight at the orifice (31).

To access the hole in the striker cover, it is then necessary to separate the cover from the striker / intermediate piece assembly. To do this, the user first presses the cover until the lugs (37) reach the horizontal junction portion. It then rotates in the opening direction, which will drive the lugs (37) from the horizontal junction portion (26) into the oblique portion (27). The movement is continued until the pins (37) come out of the oblique portions (27) of the cams thus marking the separation of the cover from the rest of the device (FIG. 6d). The user then only has to access the mixture by introducing the dosing pipette into the orifice (31).

Once the sample has been taken, the user recaps the bottle until later use. To do this, it positions the pins (37) at the entry of the cams (24) then performs a movement of the cover in the direction of screwing. The pins (37) then move in the cams (24) to join the horizontal junction portion (26). When the pins (37) abut at the bottom of the horizontal portion, they are then located at the right of the vertical portion (25).

To proceed to the next sampling, the user only has to press the cover until the lugs join the horizontal portion, then by rotating in the direction of unscrewing, the lugs then travel in the oblique portion.

The invention and the advantages which ensue from it emerge clearly from the description. We note in particular all the functions which the device of the invention combines. We can cite the sampling of a mixture of two distinct products by metering pipette while having a secure device, in particular for children, preventing unexpected access to the mixture before and after percussion.
