FR2947996A1 - Cosmetic product e.g. deodorant, refill for use in conditioning device i.e. bottle, has frangible area partially detaching fixing unit of hollow body under effect of traction exerted by user on fixing unit - Google Patents

Abstract

The refill (5) has a hollow body (9) to contain a cosmetic product and a sampling and distribution opening (11). A fixing unit (13) fixes the hollow body on a trim shell (3), and is connected to the hollow body. A frangible area (14) partially detaches the fixing unit of the hollow body under the effect of traction exerted by a user on the fixing unit, where the frangible area extends in a discrete or continuous manner on 30 percent of circumference of the hollow body. The frangible area is shifted towards an interior side of the hollow body with respect to the fixing unit. An independent claim is also included for a conditioning device comprising a cosmetic product refill.

Description

The invention relates generally to refillable cosmetic product packaging devices. There are known cosmetic product conditioning devices having a covering shell and a cosmetic product refill configured to be received in the covering shell. The refill comprises fixing means on the covering shell.

In US 5938016, the refill is secured by snapping an upper peripheral edge of the trim shell into a groove of the refill. With such a device, it is difficult to clear the edge of the covering shell out of the throat of the refill. FR 2,715,384 also describes a packaging device with a covering shell and a cosmetic product refill attached to the covering shell. The hollow body of the refill presents outward ribs coming to bear against the covering shell, and thus blocking the refill inside the covering shell. Here again it is difficult to extract the refill of the dressing shell, the user having to exert a major effort on the refill. FR 2,715,384 discloses that the hollow body may comprise pivoting tongues bearing reliefs intended to cooperate with complementary reliefs of the covering shell. These tongues make the shape of the hollow body more complex, and complicate the operating sequence necessary to separate the hollow body of the covering shell.

FR 2,745,276 discloses a cosmetic product conditioning device, with an outer casing shell, and a refill whose bottom carries pins to be engaged in force in openings of the casing shell. For the extraction of the refill, holes are provided in the bottom of the covering shell, so as to allow the introduction of a rod to push the refill upwards and disengage the pins of the refill. Such a device is not convenient to use.

In this context, the invention aims to provide a rechargeable conditioning device and a refill that are more convenient to use. To this end, according to a first aspect, the invention relates to a refill of a cosmetic product, configured to be received in a covering shell, the refill comprising: a hollow body intended to contain the cosmetic product and having a sampling aperture or dispensing cosmetic product; - Fastening means of the hollow body on the covering shell, connected to the hollow body; - A frangible zone, configured to detach at least in part said fixing means of the hollow body under the effect of a traction exerted by a user on said fixing means, the frangible zone extending discretely or continuously on to less than 30% of the circumference of the hollow body.

Thus, it is easy for the user to separate the cosmetic product refill from the covering shell, once the cosmetic product is fully used. The refill may also have one or more of the features below, considered individually or in any technically feasible combination. The fixing means of the hollow body on the covering shell can be distributed discretely or continuously and extend over at least 30% of the periphery of the hollow body. It is thus possible to easily vary the perimeter length of the fastening means around the hollow body, which makes it possible to adjust the force with which the refill is fixed to the covering shell. Moreover, the user can break in a single gesture the frangible zone over the entire length of the fastening means, which simplifies the use of the refill. The fixing means of the hollow body on the covering shell may extend over a portion of the periphery of the hollow body, the frangible zone extending along the fixing means of the hollow body on the covering shell and being offset towards the inside of the hollow body with respect to said fixing means. The user can thus separate the fixing means and the hollow body from each other by biasing the fixing means radially or in the perimeter direction, or axially. The frangible zone may constitute a connection between the fixing means and the hollow body. Only the fastening means are separated from the hollow body when the frangible zone is broken. The frangible zone may comprise a line of lesser thickness of material and / or a plurality of material bridges separated from each other by through openings. Thus, the frangible zone can be constituted in multiple ways, depending on the constraints of appearance, manufacture or use.

Moreover, it is easy to adjust the effort to be exerted by the user to break the frangible zone, by calibrating the thickness of material along the line of lesser thickness, or the material bridges section. The fixing means may comprise a retaining skirt located radially outside the hollow body and means for retaining the covering shell between the retaining skirt and the hollow body. Thus, the retaining skirt largely masks the peripheral edge of the covering shell engaging between the skirt and the hollow body. This zone, which generally includes functional reliefs and which is not decorative, is thus masked, which improves the appearance of the product.

The retaining means may be carried by an inner face of the skirt turned radially towards the hollow body. Thus, the detachment of the skirt completely eliminates the connection between the covering shell and the refill. The retaining skirt may be spaced radially from the hollow body and define with the hollow body a receiving groove of an upper edge of the covering shell. Thus, it is possible to easily set up and hooking a new cosmetic product refill on the covering shell. The groove may be closed opposite the bottom of the hollow body by a connecting flange of the retaining skirt to the hollow body. Advantageously, this flange can be used for fixing a heat-sealed protective film intended to isolate the cosmetic product before the first use.

The retaining means of the covering shell may be chosen from latching means, a thread, an adhesive tape, a loop and hook tape. The retaining skirt may have a perimeter break separating two perimeter end portions from the retaining skirt, at least one of said two perimeter end portions being a primer intended to be gripped for to separate the fastening means and the hollow body from one another. The user can thus conveniently detach the fastening means.

The primer end portion may be free from the hollow body, and be separated from the hollow body by a perimeter slot. The primer is thus particularly easy to grasp. The primer can be configured to form, after separation of the fixing means and the hollow body from one another, a gripping member for the removal of the refill out of the covering shell. The withdrawal of the refill is thus particularly convenient to achieve. The hollow body, the fixing means of the hollow body on the covering shell, and the frangible area are integral with one another. They are for example manufactured by injection of plastic into a mold. This method of manufacture is particularly economical. According to a second aspect, the invention relates to a rechargeable cosmetic product conditioning device, comprising a covering shell and a refill having the above characteristics, attached to the covering shell.

Such a packaging device is easy to use and economical to manufacture. Other features and advantages of the invention will emerge from the detailed description which is given below, by way of indication and in no way limiting, with reference to the appended figures, among which: FIG. 1 is a perspective view, exploded of the rechargeable conditioning device of the invention, showing the stacking of the various elements constituting the device; - Figure 2 is a perspective view similar to that of Figure 1, showing the refill attached to the inside of the casing shell, the cover being shown separate from the casing shell; - Figure 3 is a perspective view of the refill of Figure 1, without cosmetic product and without protective film; - Figure 4 is a radial sectional view of the refill of Figure 3; - Figure 5 is a perspective view of the device of Figure 1, the fixing means of the hollow body to the covering shell being shown partially detached; - Figure 6 is a view similar to that of Figure 3, for an alternative embodiment of the refill in which the retaining skirt is closed contour; - Figure 7 a view similar to that of Figure 3, for an alternative embodiment in which the frangible zone is a line of lesser thickness constituting the connection between the retaining skirt and the hollow body; - Figure 8 is a radial sectional view of the refill of Figure 7; - Figure 9 is a radial sectional view of an alternative embodiment of the refill of Figure 8 wherein the line of lesser thickness is formed in the hollow body; FIG. 10 is a perspective view of the refill of FIG. 9; - Figure 11 is a radial sectional view for an alternative embodiment of the refill in which the retaining means of the covering shell in the groove of the refill is a thread; - Figures 12 and 13 are views in axial section for an alternative embodiment in which the packaging device is a makeup bottle, with a flexible pocket acting hollow body; FIGS. 14 and 15 are views in axial section for alternative embodiments in which the packaging device is a bottle provided with a spraying member, with a flexible bag acting as a hollow body; and FIG. 16 is an axial sectional view for a variant embodiment in which the packaging device is a can provided with a spraying member, with a flexible bag acting as a hollow body.

The device 1 shown in FIG. 1 is intended for packaging a cosmetic product. By cosmetic product, here means a product according to the Council Directive 93/95 CE of June 14, 1993. This device comprises an outer casing shell 3 and a refill 5 removably attached to the casing shell 3. It may also include a cover 7 designed to be removably received on the outer covering shell 3. The refill 5 is configured to be received in the covering shell 3. It comprises: - a hollow body 9 intended to contain the cosmetic product and having an opening 11 for sampling or dispensing the cosmetic product; - Means 13 for fixing the hollow body 9 on the covering shell 3, connected to the hollow body 9 and projecting outwardly relative to said hollow body 9; - A frangible zone 14, configured to detach at least part of said fastening means 13 under the effect of a traction exerted by a user on said fastening means 13. In the embodiments of Figures 1 to 11, the body hollow 9 in the form of a cup, providing the user with a large opening for taking the cosmetic product.

The refill in this case may comprise a film 15, heat-sealed initially on the hollow body 9, and intended to be removed by the user at the first use. The outer covering shell 3 has an internal volume 17, delimited by a bottom 19 and a peripheral side wall 21 rising from the bottom 19. The bottom 19 is substantially flat. The device may be provided to rest normally on a support via the bottom 19. The side wall has for example a generally cylindrical shape, of central axis X substantially perpendicular to the bottom 19. It has a substantially cylindrical lower portion 23, an upper portion 25 substantially cylindrical and of reduced diameter relative to the portion 21, and a shoulder 27 connecting the parts 23 and 25 to one another. The shoulder 27 is oriented substantially perpendicular to the axis X. The upper part 25 carries the thread for fixing the cover 7.

The covering shell 3 is open to the opposite of the bottom 19, through an opening 29. The opening 29 is delimited by an upper free edge 31 of the side wall 21. The opening 29 is provided to allow the introduction recharge 5 in the internal volume 17.

The hollow body 9 is intended to be received in the internal volume 17. It has an internal space 33 for receiving a dose of cosmetic product, not shown. The space 33 is delimited downwards by a bottom 35 and laterally by a peripheral wall 37 integral with the bottom 35. The sampling opening 11 is located opposite the bottom 35, and is delimited by an upper peripheral edge 39 of the side wall 37 (Figure 3). For example, the wall 37 is slightly frustoconical and flares out from the bottom 35. The upper edge 39 has an outer diameter substantially equal to the internal diameter of the orifice 29. The means 13 for fixing the hollow body on the shell cladding comprise for example a retaining skirt 41 located radially outside the hollow body, and means 43 for retaining the covering shell 3 between the retaining skirt 41 and the hollow body 9 (FIGS. 3 and 4) . The retaining skirt 41 may be a cylindrical ring extending continuously around at least a portion of the periphery or circumference of the hollow body 9. It extends around the upper edge 39 of the side wall. Preferably, it extends along at least 30%, or at least 50%, or at least 75% or even 99% of the periphery or circumference of the hollow body. For example, it extends substantially all around the hollow body and has only a circumferential interruption of small angular width. In the embodiment of Figure 6, the retaining skirt extends continuously over 100% of the circumference or the circumference of the hollow body. The retaining skirt is then closed contour. The retaining skirt 41 is spaced radially from the hollow body 9. It defines therewith a groove 45 for receiving the upper edge 31 of the covering shell. The groove 45 is open towards the bottom of the hollow body. The retaining skirt 41 thus has a lower free edge 47 turned towards the bottom of the hollow body 35.

On the other hand, the groove 45 may be at least partially closed opposite the bottom of the hollow body, by a rim 49 connecting the retaining skirt 41 to the hollow body 9. For example, the flange 49 may be flat. It may possibly be in the plane of the sampling aperture 11. The connecting flange 49 thus defines a flat free surface intended for bonding the film 15. The connecting flange 49 secures an upper edge 51 of the skirt. 41 at the upper edge 39 of the side wall 37. The means 43 for retaining the covering shell in the groove 45 are located on a portion of the refill which is detached from the hollow body 9 when the breakable zone 14 is torn in order to to separate the fastening means 13 and the hollow body 9 from each other. The retaining means 43 are typically located in said groove 45. For example, they are located on an inner face 53 of the skirt facing the hollow body 9. Alternatively, they could be carried by the side wall 37 of the hollow body. In this case, the frangible zone 14 is located below the retaining means 43, that is to say relatively closer to the bottom 35 than the retaining means 43. The retaining means 43 can be distributed discretely or continue around the hollow body 9.

In the case where the retaining means are discretely distributed, they can be evenly distributed, equi-angularly, around the hollow body 9. Thus, if the retaining means comprise for example three distinct retaining reliefs, these reliefs can be angularly spaced from each other by 120 °. They may for example each extend about 10% of the periphery of the hollow body. The frangible zone in this case can also be discrete. It may comprise three continuous zones separated from each other, and each extending along a respective relief relief. The frangible zone can alternatively be continuous and extend along all the reliefs.

Many variations are possible. The retaining means may be discrete but be distributed irregularly around the hollow body. The frangible zone may be discrete but have a number of continuous zones different from the number of retaining reliefs, each continuous zone covering for example several reliefs.

The retaining means 43 are chosen for example from snap-fastening means, a thread, an adhesive tape, or a band with loops and hooks (Velcro tape), this list not being limiting. In the embodiment of Figures 1 to 5, the retaining means are latching means, clearly visible on the section of Figure 4. The retaining means 43 comprise a projecting peripheral relief 55, formed on the face internal of the retaining skirt. The protruding relief 55 is provided to cooperate with a complementary relief 57 (Figure 1), projecting around the upper edge 31 of the outer shell. In the embodiment of the embodiment of Figure 9, the retaining means are a thread 59 formed in the inner face of the retaining skirt. This thread is designed to cooperate with a complementary thread formed on the radially outer face of the covering shell, along the upper edge 31. The breakable zone 14 extends over at least a portion of the periphery of the hollow body 9 along means 13 for fastening the hollow body 9 to the covering shell 3. It is shifted inwardly of the hollow body 9 relative to said fastening means 13. More specifically, the breakable zone 14 extends over the entire length perimeter of the retaining skirt 41. The perimeter length of the frangible zone is then substantially equal to that of the retaining skirt. In a variant not shown, the breakable zone 14 has a perimeter length less than that of the retaining skirt 41. A portion of the retaining skirt 41 is secured to the hollow body in a non-breakable manner, for example by a bridge of material. strong section. Thus, when the frangible zone is broken in order to detach the hollow body and the fastening means from one another, the skirt remains connected to the hollow body. The frangible zone can be used to lift it.

The user has only one piece to throw in the trash, not two separate pieces (hollow body, skirt). The frangible zone 14 may be formed in the fastening means 13. The frangible zone 14 may also constitute a connection between the fastening means 13 and the hollow body 9, as in the embodiment of Figures 1 to 8. Alternatively, the frangible zone 14 may be formed in the hollow body 9, as in the embodiments of Figures 9 to 11. In the embodiments of Figures 1 to 8, the frangible zone is constituted by the flange 49 connecting the skirt restraint and the hollow body. The fringe zone can therefore be arranged at multiple points of the recharge, depending on the design of the refill and the appearance that we want to give it. The frangible zone 14 extends continuously around at least a portion of the periphery or circumference of the hollow body 9. Preferably, it extends along at least 30%, or at least 50 %, or at least 75% or even 99% of the circumference or the circumference of the hollow body. In the exemplary embodiments of FIGS. 6 and 9 to 11, the breakable zone 14 extends continuously over 100% of the periphery or circumference of the hollow body. The frangible zone 9 is then closed contour. According to a first variant embodiment, represented in FIGS. 1 to 5, the frangible zone comprises a plurality of material bridges 61 distributed perimetrically or circumferentially along the hollow body 9, and separated from each other by through apertures 63 (FIG. 3. The material bridges 61 are typically evenly spaced from each other around the hollow body, and typically have a small circumferential width, compared with the through apertures 63. The material bridges 61, and in particular their section, are calibrated to allow detachment of the retaining skirt under the effect of a moderate force pull exerted by a user on said retaining skirt The through openings 63 open into the groove 45. They pass through the connecting flange 49 alternatively, the frangible zone comprises a line 65 of lesser thickness of material. As shown in FIGS. 6 and 7, the thickness of material along the line 65 is lower than in the other parts of the hollow body, and is lower than in the other parts. parts of the fixing means of the hollow body on the covering shell.

As shown in Figures 1 and 3, the retaining skirt may have a perimeter or circumferential interruption 67, separating from one another two parts of circumferential or perimeter ends 69, 70 of said retaining skirt. The two ends 69, 70 are free relative to each other. One of the two end portions constitutes a primer intended to be grasped by a user in order to detach the fastening means. The primer end portion 70 is free from the hollow body 9. It is separated from the hollow body by a circumferential or perimeter slot 71 constituting part of the groove 45.

The interruption 67 may be of circumferential length or variable perimetric. It can be very small, as shown in Figure 10, and cover an angular sector less than 5 °. It can be wider, as illustrated for example in Figure 3, and cover for example an angular sector of 15 ° Alternatively, the primer 70 may be connected to the hollow body 9 by the frangible zone 14, as shown in FIG. 7. The lid 7 is provided to cap the refill 5, and close the sampling opening 11. It has a lower peripheral edge 73, provided to bear on the shoulder 27 when the lid is attached to the shell dressing.

The assembly and disassembly of the packaging device will now be detailed, in particular with reference to FIGS. 1, 2 and 5. The user purchases a refill of a cosmetic product, with a hollow body, a dose of cosmetic product filling the internal space 33 of the refill, and a heat seal film 15 on the hollow body, so as to close the sampling aperture. Thus, the cosmetic properties of the product are preserved, the latter being isolated from the ambient air. The refill comprises the means 13 necessary for fixing the hollow body to the covering shell 3. The refill also comprises the breakable zone 14 provided to allow the separation of the refill and the outer covering shell once the cosmetic product fully used. To fix the refill on the covering shell 3, the user directs said refill so that the bottom 35 of the hollow body is placed above the opening 29 of the covering shell, as shown in FIG. 1.

The user then introduces the refill into the internal volume 17 of the covering shell, the bottom 35 being introduced first. During this movement, the upper edge 31 of the outer shell penetrates inside the groove 45. As a result, the retaining means 43 block the upper edge 31 in said groove between the retaining skirt 41 and the hollow body 9. The detent relief 57 engages with the corresponding detent relief 55 carried by the retaining skirt. For example, the edge 31 may be, in this situation, abut against the rim 49 connecting. The retaining skirt 41 is then applied against the outer surface of the covering shell, as can be seen in FIGS. 2 and 5. The refill is then almost entirely housed in the internal volume 17 of the covering shell. Only the retaining skirt 41 and the connecting flange 49 remain visible, as well as the heat-sealed film 15 on the connecting flange 49.

The user can then replace the cover 7, so as to close the opening 11 and to completely hide the refill. In the embodiment of Figure 11, the establishment of the cosmetic product refill on the covering shell is made by screwing. At the first use, the user removes the lid 7, separates the film 15 from the hollow body, and takes the amount of cosmetic product it needs. It then puts back the cover 7. When the cosmetic product stored in the refill has been fully used, the user has the possibility of separating the refill from the covering shell, and replace the empty refill with a new full refill. of the same type.

To do this, it grasps the end portion 70 of the retaining skirt forming a primer. It radially spreads the end portion 70 of the refill, exerting a sufficiently strong pull to break the frangible zone in the vicinity of the primer 70. In the example of Figures 1 to 5, the user spreads sufficiently the primer 70 of the refill, so as to break the material bridges 61 immediately adjacent to the primer 70. The user then continues to spread the retaining skirt radially, rotating the covering shell, to break thus successively all material bridges 61. When a sufficient number of material bridges has been broken, the user can easily separate the empty refill from the covering shell by exerting axial traction on the refill. Indeed, a small axial traction is then sufficient to clear the upper edge 31 of the covering shell out of the groove.

As illustrated in FIG. 5, in the zone where the bridges of material are broken, the retaining skirt can be moved away from the hollow body, and no longer retains the upper free edge 31 of the outer shell. It is no longer blocked on a part of its periphery, in the area where the material bridges have not been broken. The force holding the free edge in the groove is thus greatly diminished, so that it is easy for the user to clear the edge 31 out of the groove by pulling the refill upwards. As the frangible zone breaks, the primer unfolds as a web, configured to act as a gripping member for removal of the refill from the shell.

The user can also extract the empty refill from the gravity shell, by inverting the conditioning device. The user could also pull the primer 70 upwards, that is to say along the X axis opposite the bottom 35 of the hollow body. It can then practically in one gesture break all the bridges of material and release the refill 5 of the covering shell 3. In the case of FIGS. 7 to 11, the traction exerted by the user on the primer 70 makes it possible to breaking the frangible zone along the line of lesser thickness of material 65. The gesture of the user to break the frangible zone is substantially the same as for the embodiment of Figures 1 to 5. Once the recharge empty separated from the dressing shell, the user can set up a new refill of cosmetic product, full, according to the sequence of operations described above. The conditioning device and its recharging can have multiple variants. In the embodiments above, the outer shell and the refill are circular in geometry. However, they could have any kind of section, rectangular, oval, regular or irregular.

The retaining skirt may have any length axially, and is not necessarily low in height compared to the hollow body. The retaining skirt advantageously has a perimeter or circumferential interruption, so as to create a primer intended to be grasped by the user. It could also comprise two perimeter or circumferential interruptions, or more than two perimeter or circumferential interruptions, thus subdividing the skirt of retained in several continuous sections separated from each other. The cosmetic product can be of any type, solid, liquid, gaseous, pasty, more or less fluid. The cosmetic product may be a care product for the face or the body, a makeup product, such as a foundation, a styling product such as a gel or a hair wax, a hair mask, a product The invention has been described above with reference to Figures 1 to 11 in an application where the hollow body is a cup, for example intended to receive a creamy product. However, the hollow body could be a flexible pouch, as illustrated in Figures 12 to 16. The covering shell could be a bottle (Figures 12 to 15) or an aerosol container (Figure 16). The flexible pouch can be made with different materials and in particular with a composite sheet. Such a sheet may comprise for example a multilayer complex comprising: a metal layer, for example made from aluminum or an alloy comprising aluminum, an adhesion agent on one side of this metal layer , comprising, for example, a copolymer comprising at least 7% by weight of carboxylic and / or carboxylate units, the carboxylic units possibly being in acid form, and a layer of a non-metallic material bonded to the metal layer via the adhesion agent, for example a thermoplastic material, preferably a polymer, for example polyethylene. The carboxylate unit is, for example, an acrylate or methacrylate unit, for example ethyl acrylate. The carboxylic unit is, for example, acrylic or methacrylic acid. The copolymer may comprise at least one second monomer having an alkylene unit whose alkyl chain comprises from 2 to 10 carbon atoms. The adhesion agent is for example a copolymer of ethylene and ethyl acrylate or a copolymer of ethylene and acrylic acid. The adhesion agent may comprise, for example, between 7 and 19%, more particularly between 8 and 11%, or even between 8.5 and 10.5%, and preferably 9.7% by weight, of an acrylic acid or an acrylic ester. The composite structure may comprise a second outer structure contiguous to the metal layer, this outer structure may be made of a thermoplastic material, in particular a polymer, for example polyethylene terephthalate, and being intended to define the outer surface of the pocket. This outer structure may be integral with the metal layer by means of a layer of a second adhesion agent, in particular a polyurethane-based adhesive. Other composite sheet structures are possible. Such a bag is particularly suitable for the packaging of a cosmetic or dermatological product, such as a hair coloring product to be stored in the absence of air. Alternatively, the flexible pouch may be in the form of a tube, optionally provided with an outer collar. This tube may be made of one or more elastomeric material (s), for example natural or synthetic rubber. It is particularly suitable for the device of Figures 12 and 13, which is intended for packaging a makeup product. The invention is not limited to a particular pocket shape and this may be more or less elongated, the terms bag and tube being considered synonymous in the present application. Also note that this flexible bag can be provided for a system with or without air intake. This pocket can thus be configured to retract with each distribution or product withdrawal.

The embodiments of Figures 12 to 16 will now be detailed. The identical elements or providing the same function as in the embodiments of Figures 1 to 11 will be designated by the same references. Only the points by which the variants of FIGS. 12 to 16 differ from the variants of FIGS. 1 to 11 will be described below. The packaging device of Figures 12 and 13 is a bottle for receiving a makeup product. It may comprise, in addition to the covering shell 3 and the refill 5, a plug 77 and a sampling member 79 integral with the plug 77. The sampling member may be for example a brush or a mascara brush. The hollow body 41 is a flexible tube 81 provided with an external flange 83 delimiting the sampling opening 11. The flexible tube is as described above. The refill also comprises a tubular wiper 85, coaxial with the covering shell 3. An upper part of the wiper 85 has an external thread 87, intended to cooperate with a tapping 89 formed in a blind hole 91 of the stopper. . The wiper has an internal channel 93. A lower portion of the wiper is curved so as to partially close the internal channel 93 and define a wiper orifice 95 of the sampling member. The orifice 95 is provided to remove the surplus of cosmetic product on the applicator. The refill further comprises an annular plate 97 secured to an outer peripheral face of the wiper 85 and protruding radially outwardly from the wiper 85. The plate is for example substantially perpendicular to the central axis of the wiper. the dressing shell. The retaining skirt 41 extends around the annular plate 97. The connecting flange 49 secures the upper edge of the skirt 41 to the plate 97.

The frangible zone 14 may be formed in the connecting flange 49, in the skirt 41 or in the lower part of the wiper 85, that is to say between the annular plate 97 and the wiping orifice 95 The conditioning device is illustrated in Fig. 13 in the assembled state.

The flexible tube 81 is engaged inside the covering shell 3, the outer flange 83 bearing axially on the upper edge 31 of the covering shell.

The wiper 85 is partially engaged in the tube 81, through the sampling opening 11. The annular plate 97 bears axially on the outer collar 83, and clamps this collar against the upper edge 31 of the covering shell . The retaining skirt 41 is located around the covering shell, the upper edge 31 of the shell being engaged and locked between the flexible tube 81 and the retaining skirt 41. The sampling member 79 can be introduced to the inside the hollow body 9 through the inner channel 93 of the wiper. The end of the sampling member is then immersed in the cosmetic product. The cap can then be screwed onto the thread 87 of the wiper. When the sampling member 79 is extracted from the hollow body, this member is drained by passing through the wiping orifice 95. When all the cosmetic product has been consumed, the user can easily separate the refill 5 from the shell 3, by tearing the frangible zone, as in the embodiments of FIGS. 1 to 11. The user can then separate the wiper 85 from the shell 3 with the annular plate 97, then the hollow body 9. The packaging devices of FIGS. 14 and 15 are flasks intended to receive a liquid cosmetic product or in the form of an aerosol.

The hollow body 9 of the refill comprises a flexible bag 98 as described above and a fixing ring 99. The refill 5, in addition to the hollow body 9, comprises a body 100 for dispensing the cosmetic product. The opening 11 of the hollow body is here a distribution opening and not sampling. The flexible bag 98 is sealingly attached to the peripheral ring 99. It is for example welded to the peripheral ring. The dispensing member 100 comprises a body 101, an actuating rod 103 movable relative to the body 101, and a sleeve 105 for connection to a plunger tube 107. The plunger tube is disposed inside the hollow body.

The body 101 is sealingly mounted in the peripheral ring 99. The dispensing member may comprise a pump or a valve (not shown) for taking in the hollow body 9 a metered or non-dosed quantity of cosmetic product to be dispensed. This dispensing member can thus define a metering chamber of the product to be dispensed, possibly equipped with an inlet valve and an outlet valve (not shown). The body 101 internally defines a guide surface for the actuating rod 103. This rod is axially displaceable by sliding inside the body 101, for the purpose of dispensing the product. The actuating rod 103 internally defines a product dispensing channel. The rod is movable against the body so as to vary the volume of the metering chamber for the purpose of expelling the product through the dispensing channel. The rod 103 is typically integral with means of reminders (not shown) housed in the body 101 and urging the rod axially outwardly of the container. The rod 103 is located outside the hollow body. The dispensing member 100 may further comprise an actuating member 111 mounted, if necessary to be fitted, on the actuating rod 103 of the dispensing member. The actuating member is for example a push button. The actuating member may comprise a channel 113 for dispensing cosmetic product, ending at one end with a blind housing 115 for receiving the actuating rod. The other end of the distribution channel 113 is a nozzle for spraying the cosmetic product. The actuating member may also include a nozzle designed to eject the cosmetic product to the outside. The retaining skirt 41 extends around the fixing ring 99. It defines with the fixing ring the groove 45 for receiving the upper edge 31 of the covering shell. The connecting flange 49 secures the upper edge of the skirt 41 to the fixing ring 99. The breakable zone 14 may be formed either in the connecting flange 49, or in the fixing ring 99, or the skirt 41. 14, the upper edge 31 of the covering shell is engaged in the groove and is supported both against the retaining skirt 41 and against the fixing ring 99. The flexible bag 98 is supported on the bottom 19 of the dressing shell. In FIG. 15, the upper edge 31 of the covering shell is engaged in the groove but bears only against the retaining skirt 41. It is separated from the fixing ring 99. The flexible bag 98 is suspended to the fixing ring and is not supported on the bottom 19 of the covering shell. The devices of FIGS. 14 and 15 may comprise a cover (not shown) intended to cap the actuating member and to be removably attached to the covering shell. The packaging device of FIG. 16 is a container intended to receive a liquid cosmetic product or in the form of an aerosol. It is very close to that of Figure 14. The device of Figure 16 differs from that of Figure 14 by the shape of the covering shell. It is also distinguished by the shape of the peripheral ring 99, which is wider in Figure 16.
