Description

TECHNICAL FIELD

[0001] The present invention relates to the field of replaceable packaging devices for cosmetic products. By cosmetic products, it is meant in particular all products for making up the skin, including the lips, and all constituents for making up the body, including health-care products such as skin creams. The present invention relates in particular to the field of the replacement part of replaceable packaging devices for cosmetic products. BACKGROUND

[0002] By packaging device for cosmetic products, it is meant in particular any container for containing a cosmetic product, intended to preserve, transport, sell or use the cosmetic product. Thus, it is meant in particular a jar, a bottle, a box, etc. for containing a cosmetic product.

[0003] By replacement part, it is meant a removable member having a container adapted to contain a cosmetic product, which can be arranged in and extracted from a housing, said housing forming the outer surface of the replaceable packaging device for cosmetic products constituted by the housing and the replacement part.

[0004] Once arranged in the housing, the replacement part must be correctly held in the housing. In particular, it should be avoided that the replacement part comes out of the housing during transport or use, when the container can take any orientation, in particular a complete inversion of the packaging device, caused by human action or not. In addition, the replacement part must not move in the housing during use of the packaging device. The replacement part must remain fixed during dispensing of the cosmetic product, for example when the user extracts the cosmetic product from the replacement part.

[0005] However, the replacement part must be easily extractable from the housing in order to be replaced.

[0006] The known replaceable packaging devices generally have a holding system for holding the replacement part in the housing, which can be seen, is not very aesthetic and / or requires an industrially complex assembly, which is costly.

[0007] Thus, JP2013119399 proposes a cosmetic jar having a replacement part, the container of which is substantially cylindrical and has a protrusion which slides by shape correspondence in a vertical groove in the housing, preventing the container from rotating.

[0008] EP0661012 also proposes a replaceable jar device having an inner container which engages by shape correspondence in an outer container forming the housing, the inner container in particular having a peripheral flange which cooperates with a groove formed in the neck of the outer container.

[0009] WO2019058087 also proposes a similar replaceable jar device having an inner container which is engaged by shape correspondence in an outer container forming a housing, the peripheral flange of the housing cooperating with a groove formed on the outer surface of the container. The upper part of the housing has a neck with a slit in which a radial flange of the container is inserted to retain the container in rotation.

[0010] Thus, the replaceable packaging devices known in the prior art, based on the shape correspondence between the housing and the replacement, retain the replacement in the housing, for example by clamping (or relative mechanical engagement). This requires a special shaping of the housing and of the replacement, for example a housing which cannot be of a usual shape, such as a standard glass container, to form a replaceable packaging device, and likewise a replacement which cannot be of a usual shape, such as a glass container or a stainless steel container of usual shape.

[0011] The present invention aims to solve all or part of the aforementioned problems. SUMMARY

[0012] The present invention thus relates to a housing for a replaceable packaging device for a cosmetic product. The housing is suitable for receiving a replacement adapted to contain said cosmetic product. The housing has an opening suitable for receiving the replacement so as to arrange the replacement in a receiving volume defined by the inner wall of the housing. The inner wall has, on at least one part of its surface, an elastomer material member connected to the housing and at least partially protruding with respect to the inner wall of the housing.

[0013] By means of the elastomer material protrusion formed on the outer wall of the container, the housing thus formed is suitable for retaining a replacement having an appropriate shape. With the elastic properties and the coefficient of friction of the elastomer material, retention is obtained but the replacement is allowed to be removed. The replacement is thus very simple to implement.

[0014] The elastomer material member can be overmoulded on the housing.

[0015] The housing can be made of plastic. The housing and the elastomer material member it has can be formed together by bi-material injection.

[0016] The housing can thus be produced with known industrial methods mastered which provide good adhesion between the housing and its elastomer material member.

[0017] The elastomer material used can be a thermoplastic elastomer material or a silicone elastomer material. Its hardness can be between 20 Shore and 80 Shore, preferably between 40 Shore and 60 Shore.

[0018] The elastomer material used and its hardness allow deformation under an appropriate force, in line with the forces exerted on the cosmetic product replacement.

[0019] The elastomeric material member can extend along one or more bands parallel to the opening of the housing.

[0020] The elastomeric material member forms a contact point discretely distributed on the surface of the inner wall of the housing.

[0021] The elastomeric material member can form at least two contact points, preferably at least three, on the periphery of the surface of the inner wall of the housing.

[0022] The different configurations of the elastomeric material member can accommodate the application support area, the retention of the insert, the retention force, the aesthetics, the complexity of implementation, etc.

[0023] In such a housing, the receiving volume can be substantially a revolution cylinder, or a truncated cone, a regular prism.

[0024] Reference is made to the particular configurations suitable for implementing the application.

[0025] A portion of the inner wall of the housing forms a neck near the opening of the housing, the elastomeric material member being located on said portion of the inner wall of the housing forming the neck.

[0026] The housing can be made, for example, of plastic, glass, stainless steel, aluminum or wood. In fact, the housing has an aesthetic appearance that is extremely important in the cosmetics field.

[0027] The application also relates to a packaging device for cosmetics, having a housing as described previously, defining an insert, in which the insert has a lateral wall having a clearance with respect to the inner wall of the housing, except at the elastomeric material member, in its entirety or in part, so as to form a support area on which the elastomeric material member is supported on said lateral wall of the insert.

[0028] Since the retention of the insert in the housing is ensured at the support area, the means that carry out this retention are invisible (if the housing is not transparent) or at least very discreet, so as not to affect the aesthetics of the jar constituted.

[0029] The elastomeric material member is deformed at said support area by pressing on the lateral wall of the insert, compared to the configuration in which it is placed in the absence of an external action.

[0030] The deformation of the elastomeric material member on the support area increases the force that it exerts on the inner surface of the housing, thus increasing the friction for extracting the insert.

[0031] In one embodiment, the lateral wall of the insert does not have a relief surface, for example grooves, holes, pins or locking rings.

[0032] Since one member is in the other having a corresponding shape, the holding of the replacement does not require any special shape to be formed on it which cooperates with the holding member of the casing, not based on the principle of locking or screwing or other engagement.

[0033] In the above packaging device, the container of the replacement injects the cosmetic product, the casing and the replacement can be configured so that the force required to extract the replacement is greater than or equal to twice the weight of the replacement, preferably greater than or equal to two and a half times the weight of the replacement. In particular, the shape, size and structural configuration of the elastomeric material member are configured so as to obtain the action force required to extract the replacement.

[0034] This holding force allows easy extraction of the replacement, making the replacement of the replacement easy. It corresponds to an ideal technical specification for a common cosmetic jar.

[0035] The packaging device can be in particular a jar, for example a jar of skin cream. BRIEF DESCRIPTION OF DRAWINGS

[0044] Figure 1 a first embodiment of a replacement 1 suitable for use in a replaceable cosmetic packaging device according to an embodiment of the present application is shown in perspective view.

[0045] The displacement 1 has a container 2 which is hollow, i.e. which has a shape with a volume suitable for receiving a cosmetic product. In the embodiment shown here, the container 2 is substantially cylindrical, possibly a right cylinder, or slightly flared (frustoconical). However, any hollow shape can be used to form the container, in particular any right prismatic shape, in particular with a square base, a rectangular base, a pentagonal base, a hexagonal base, an octagonal base, etc.

[0046] The container 2 has in particular a side wall 3 and a bottom 4.

[0047] In the embodiment shown, the container has a flange 5 on the upper part. The flange 5 is formed around the open end face 6 of the container 2.

[0048] A cosmetic product, for example a skin cream, can be contained in the volume inside the container. The open end face of the container can be covered with a removable cap, for example a cosmetic protection disc, which is supported for example on the flange 5 and / or on a shoulder formed by the upper part of the container. The container can also have a cap, for example a heat-seal cap, which covers the open end face 6 before the cap is removed at the first use of the displacement. The open end face can be free, directly revealing the cosmetic product in the container 2 of the displacement, or equipped with a regulating device, for example a filter, a threaded face, or other suitable device for the cosmetic product to be dispensed.

[0049] The displacement thus has a generally simple shape.

[0050] Here, the displacement, in particular its side wall 3, and in particular the outer surface 7 of the side wall 3, does not have a rough surface or other locking means.

[0051] By a rough surface, it is meant a surface which has a relief and dimensions which are much greater than the roughness which can exist in relation to the material of which the surface is made. The surface of the side wall 3 in particular does not have any grooves, any holes, any pins, or any locking ring.

[0052] The displacement is thus easy to produce, or can be composed of a standard container, for example a plastic jar, a glass jar or a stainless steel jar.

[0053] The displacement can be used in a container which is original, for example a conventional glass container, without modification, and can be used as a displacement for a cosmetic packaging device.

[0054] The manufacturing cost of the container (and of the finished packaging device) can thus be reduced, compared with a packaging device in which the container must have special fixing means which are fixed in the housing.

[0055] Figure 2 One embodiment of a housing 8 is shown, which can be used for the displacement 1 of the application, for example Figure 1The illustrated replacement forms a cosmetic packaging device (here a jar).

[0056] The housing refers to a member adapted to receive the replacement and to retain the replacement therein. Figure 2 The illustrated housing is a bottle which forms a receiving volume adapted to receive the replacement 1 by the opening 9.

[0057] The housing 8 has a main body 10 which is substantially prismatic in shape with a square base, the main body being slightly convex on its sides. Once the jar is constituted, the housing 8 constitutes the visible part of the jar, having a very aesthetic effect. The main body 10 of the housing 8 is surmounted by a neck 11 which is provided with a threaded face 12, the threaded face being adapted to receive a screw-on cap (not shown).

[0058] A shoulder 13 is formed at the mouth of the neck 11. The shoulder 13 is dimensioned so as to be able to support the flange 5 of the container 2 of the replacement 1.

[0059] The shoulder 13 is optional, the replacement being able to be supported vertically on other surfaces of the housing, for example, the flange 5 of the container 2 of the replacement 1 being able to be supported directly on the neck 11, or for example, in the absence of a flange 5 on the container 2 of the replacement, the bottom 4 of the container being able to be supported on the bottom of the housing if the housing has a bottom. A housing 8 without a bottom is advantageous for easy removal of the replacement.

[0060] The housing has, on its internal wall 14, a member 15 of elastomeric material. The member 15 of elastomeric material is tightly connected to the housing.

[0061] Generally, the member of elastomeric material can be overmoulded on the housing 8.

[0062] The overmoulding of the member 15 of elastomeric material on the housing 2 can be carried out in particular on a housing 8 made of plastic, metal, glass or other overmouldable material.

[0063] When the housing 8 is made of plastic, the member 15 of elastomeric material and the housing 8 can be formed by bi-material injection.

[0064] The elastomeric material used to form the member of elastomeric material includes all thermoplastic elastomeric materials (TPE) as well as silicone elastomeric materials. Advantageously, the Shore hardness of the material used is between 20 Shore and 80 Shore (preferably between 40 and 60 Shore).

[0065] The hardness of the material used is an important parameter for the optimization of the replacement, in particular according to the dimensions of the container of the replacement, according to the material used to form the housing receiving the replacement to form the cosmetic packaging device.

[0066] The member 15 of elastomeric material is raised with respect to the internal wall 14 of the housing 8.

[0067] In other words, on at least one part of the elastomeric material member 15, the elastomeric material member 15 is raised with respect to the inner wall 14.

[0068] Thus, the contacts 16 can be formed by the elastomeric material member 15. These contacts 16 form a part of the elastomeric material member which has the role of retaining the replacement part 1 in the receiving volume, as will be detailed later.

[0069] The number, size, shape and orientation of the contacts 16 can vary depending on the application. Generally, the configuration of the elastomeric material member is very versatile.

[0070] According to Figure 2 In the first configuration shown, the elastomeric material member 15 forms a peripheral band on the inner wall 14.

[0071] This band is formed in the upper part of the container 2, here below the flange 5. It has three contacts 16 distributed along the periphery of the inner wall 14 having said band.

[0072] Except for the contacts 16 which must be raised with respect to the inner wall 14 of the housing 8, the other parts of the elastomeric material member 15 can be raised or flush with the inner wall 14.

[0073] To this end, a groove can be formed in the inner wall 14 so as to receive said elastomeric material member 15.

[0074] The distribution of the three contacts 16 is preferably symmetrical, i.e. the contacts are distributed equidistantly along the band formed by the elastomeric material member 15.

[0075] In the case where the opening 9 of the housing, generally defined by the neck 11, has a revolution shape, this manifests itself in a symmetrical distribution of the contacts 16 at an angle with respect to the axis of revolution of the opening 9 of the neck 11.

[0076] In this embodiment, the contacts 16 are arranged vertically, i.e. the contacts are elongated from the top (opening of the neck 11 of the housing 8) to the bottom (bottom of the housing 8 if said housing has one).

[0077] Generally, the contacts are positioned vertically to the plane defined by the opening 9 of the housing for the insertion of the replacement part 1.

[0078] In this embodiment, the number of contacts formed by the elastomeric material member can easily be varied with slight modifications of the production tool.

[0079] According to one embodiment of this embodiment, the elastomeric material member 15 is formed by a plurality of contacts 16 which are not necessarily connected by a band of elastomeric material.

[0080] Figure 3The housing 8 of the second embodiment of the present invention is shown in a perspective view. Figure 3 The implementation methods shown are the same as Figure 2 The implementation methods shown are essentially the same, making them applicable. Figure 1 The description is provided, except for the configuration of the elastomeric material member 15. Here, the elastomeric material member 15 has the shape of two parallel strips protruding relative to the inner wall 14 of the shell.

[0081] Many other configurations of the elastomeric material component 15 may be considered, such as a single strip, a zigzag strip, or a corrugated strip that protrudes relative to the inner wall 14 of the housing, one or more strips combined with the contact 16, and so on.

[0082] Figure 4 The housing 8 of a third embodiment of the present invention is shown in perspective. This embodiment is similar to... Figure 1 The embodiments shown are essentially the same, making their description applicable, except for the shape of the internal volume of the housing. Figure 4 The illustrated implementation shows that, in order to ensure Figure 5 and 6 As shown, the receiving volume of the replacement member and the shape of the replacement member are not necessarily perfectly aligned across the entire surface of the replacement member. In the housing embodiment shown here, the inner wall of the housing 14 forms a neck near the housing opening 9. Below the neck 11, the receiving volume is flared. Thus, the housing has the shape of a typical can or bottle, wherein the cross-section of the internal volume of the can is larger than the cross-section of its opening 9. An elastomeric material member 15 is located on the portion of the inner wall of the housing that forms the neck 11. Therefore, the retention of the replacement member 1 in the housing 8 occurs only at the neck 11.

[0083] Figures 2 to 4 The shell shown can be formed from various materials (except for elastomeric material components). For example, the shell can be formed from glass. Any type of glass can be used, especially transparent glass, translucent glass, opaque glass, colored glass, or colorless glass.

[0084] The casing can be made of many other materials, depending on the desired appearance, volume, shape, closure method, and so on. In particular, the casing can be made of plastic, wood, or metal (such as stainless steel, galvanized iron, or aluminum).

[0085] Figure 5 Shown in cross section Figure 2 The shell shown is Figure 1 The packaging device formed by the replacement component shown is a can. The cross-section is the radial plane of the shell 8, as shown... Figures 2 to 4 As shown (plane P).

[0086] therefore, Figure 5The illustrated pot has a casing 8 which is a thick-walled container forming a receiving volume which receives the replacement part 1.

[0087] Thus, in the illustrated embodiment, the internal volume of the casing 8 has a shape which corresponds to the outer shape of the container 2 (cylindrical or slightly truncated-cone shaped, for example) with a certain clearance. The depth of this internal volume is slightly greater than the overall height of the replacement part 1 so that the flange 5 of the replacement part bears on the shoulder 13 formed at the opening of the neck 11.

[0088] Figure 6 is a detail view, in the same cross-section as Figure 5 illustrated, of the interaction between the casing 8 and the replacement part 1 in the pot illustrated. Figure 5

[0089] Figure 6 In particular, the support formed between the flange 5 and the shoulder 13 of the casing 8 is illustrated.

[0090] Between the internal wall 14 of the casing 8 and the outer surface 7 of the side wall 3 of the container 2, there is a clearance J which is, for example, about 0.5 mm, for example about 60 ml, for a cosmetic pot of usual volume.

[0091] In the illustrated embodiment, the elastomeric material member 15, which forms the contact 16 and which is raised with respect to the internal wall 14 of the casing 8, is flush or almost flush with the surface of this internal wall 14.

[0092] When the contact is not subjected to an external mechanical stress, in particular when the contact 16 is not compressed, each contact 16 forms a protrusion at the internal wall 14, the thickness E of which is greater than the clearance J.

[0093] This free configuration of the contact 16 is illustrated in dotted lines in Figure 6 In the illustrated embodiment, the thickness E can be about 1 mm, for example about 0.9 mm.

[0094] In order to insert the replacement part 1 in the casing 8, up to the support of the flange 5 on the shoulder 13, it is necessary to deform the contact 16 in order to insert the replacement part 1 in the casing 8.

[0095] When the replacement part 1 is in the casing 8, the contact 16 is compressed, and its thickness is therefore equal to the thickness of the clearance J. Thus, the contact 16 fills the clearance J and exerts a bearing force on the side wall 3 of the container 2 of the replacement part 1 by virtue of its elasticity.

[0096] Advantageously, a plurality of bearing contacts are provided around the container 2 so that these bearing contacts are distributed on the side wall 3 of the container and ensure that the container 2 is held uniformly and effectively in the casing 8.

[0097] ​In fact, each support area formed at each contact 16 forms an area that ensures the containment of the container 2, and therefore of the replacement 1, in the housing 8. When an action tending to extract the replacement 1 from the housing 8 is applied, due to the interaction between each contact 16 and the side wall 3 of the replacement 1 on which the contact 16 is compressed, a counteraction opposite to the extraction action is formed at the contact. This action is generated by the friction of the contact 16 on the inner wall 14 of the housing 8.

[0098] When the container 2 is fixed in the housing 8, for each contact 16 the intensity of the dry friction action is at most equal to the static friction coefficient between the contacts 16 multiplied by the action applied by the compression thereof between the inner wall 14 of the housing 8 and the contact 16. When the action tending to extract the container from the housing 8 exceeds the maximum static friction action applied at the contacts 16, the replacement starts to move with respect to the housing 8 in order to be extracted.

[0099] Therefore, it is clear that the number, size, elastomeric material used for the contacts, the material of which the container 2 is made, and the condition of the outer surface 7 of the side wall 3 of the container, are parameters that condition the action required for arranging and extracting the replacement 1.

[0100] As regards the elastomeric material member, the material of which it is made, the total support surface (sum of the support surfaces) between the elastomeric material member and the outer surface 7 of the side wall 3 of the container, and the sum of the actions applied by the compression of the elastomeric material member, are decisive parameters that determine the configuration of the elastomeric material member.

[0101] Irrespective of the embodiment, for a cosmetic jar it is recommended that the action required for extracting the replacement be at least greater than twice the weight of the replacement when full, for example about two and a half times the real weight of the replacement when full.

[0102] As in the illustrated embodiment, the presence of at least three contacts uniformly distributed also allows the replacement to be centred in the housing 8.

[0103] In order to facilitate the arrangement of the replacement 1 in the housing 8, in the illustrated embodiment the contacts 16 are formed by a plurality of elastomeric material members 18. Figure 6 In the illustrated embodiment, the contacts 16 have a convex, bevelled or chamfered shape along a vertical direction that also corresponds to the direction of insertion (and extraction) of the replacement. In this way, the contacts can be gradually compressed when the replacement 1 is inserted in the housing 8.

[0104] In the illustrated embodiment, the contacts 16 have an elongated shape that is vertical, i.e. parallel to the direction of insertion and extraction of the replacement. In order to facilitate the insertion of the replacement 1 in the housing 8, a bevel 17 is formed on the contacts 16.

[0105] Although the support of the three embodiments has been described in detail, it is clear that the application is not limited to these embodiments. In particular, the respective configuration of the elastomeric member, of the insert and / or of the housing can be very different from the one described above. For example, the presence of the contact on the elastomeric member is optional, at least a portion of said elastomeric member being raised with respect to the inner wall of the housing. The elastomeric member can have a very varied shape.

[0106] A plurality of different elastomeric members can be configured on the same housing.

[0107] The container can have various shapes and structures, according to the desired application. Likewise, the housing can have various shapes and structures.

[0108] For example, the container can be square, cylindrical, parallelepiped, spherical, with or without a base, or provided with a hole in its base to facilitate the removal of the insert.

[0109] The application thus improved makes it possible to removably retain a cosmetic insert in a housing, so as to form an aesthetic and replaceable insert cosmetic packaging device. The retention is obtained by the friction of the elastomeric member on the outer surface of the wall of the insert. The retaining member, in particular the elastomeric member, can be completely invisible once the jar is assembled, and can be slightly visible in the housing.

[0110] In addition, the insert can have a simple shape that is easy to produce, since the outer surface of the container of the insert, which is intended to interact with the elastomeric member of the housing to retain the insert, does not need to form any particular mechanical means. Thus, it is possible to use a conventional container, for example a conventional glass container, a simple plastic container, a metal container, etc., without the need to modify the container of the insert of the cosmetic packaging device.
