Field of the invention

The present invention relates to a device for packaging a product, in particular a cosmetic product or a care product, for example a makeup product.

The invention more particularly concerns, but is not limited to, a device comprising a container housing a product to be applied and a flexible porous membrane through which the product housed in the container can exit for dispensing.

Background of the invention

Numerous devices of this type are known, having various shapes and arrangements.

For example, WO 2017/155301, FR 3 027 200, JP H09 289918 relate to devices having a container of product provided with a porous membrane through which the product can be picked up.

Two categories of containers of product provided with a porous membrane through which the product can be picked up have to be distinguished.

In the first category, the porous membrane is a follower, that is to say may descend in the container during the dispensing of the product as the amount of product decreases in the container.

In this first category, KR 10-1477583 discloses a portable cosmetic product consisting of an external container with an upper portion open and provided with an accommodation space inside; an internal container accommodated in the accommodation space, with an upper portion open to accommodate a cosmetic in liquid phase or cream phase inside; a mesh portion mounted on top of the cosmetic accommodated in the internal container; a guide member in a ring shape mounted along the perimeter of the mesh portion; a container cover covering the open upper portion of the external container; and the cosmetic accommodated in the internal container. At the upper face of the external container, a first container protrusion and a second container protrusion protruded in a ring shape along a perimeter are formed. At the bottom face of the container cover, a first cover protrusion and a second cover protrusion protruded in a ring shape inside and outside of the first container protrusion are formed. A mounting groove is formed between the first container protrusion and the second container protrusion. A sealing member is mounted on each of the second container protrusion and the mounting groove. The guide member consists of a lower guide in a ring shape wherein a plurality of protrusions is formed protruding in a radial direction on an upper face and an upper guide coupled to surround the side face perimeter of the lower guide, the upper guide being positioned on top of the lower guide. The perimeter of the mesh portion is interposed and fixed between the lower guide and the upper guide.

The second category, to which the present invention belongs to, comprises devices wherein the porous membrane is not a follower, that is to say does not descend within the container during the dispensing of the product.

In this second category, FR 3 043 896 relates to a device comprising a container having a container body for storing a cosmetic, an inner lid including a hollow cylindrical frame and a cosmetically permeable fiber sheet having resiliency and being attached to the hollow cylindrical frame under tension and a sealing cover being configured to seal the container body in a state where the inner lid is secured. The frame is fitted to the container body. The fiber sheet has a peripheral edge adhering either from an upper end surface or from a lower end surface of the frame and along an inner circumferential face of the frame.

Also in this second category, KR 2016/0073895 relates to a cosmetic container, comprising a container main body portion, a cosmetic containing portion which is joined with the container main body portion and holds a cosmetic therein and a mesh frame portion which is joined with the cosmetic containing portion and to which a mesh is attached by welding, at least one joining member which is formed on the inner side of the mesh frame portion to be joined with the mesh and a fixing joining portion which is provided at the outer circumference of the container main body portion and presses and pulls the mesh to fix it while being joined with the joining members, wherein the joining members comprises a first joining member which is formed protruding on the inner bottom surface of the mesh frame portion to be joined with the mesh and a second joining member which is formed on an inner side surface of the mesh frame portion to be joined with the mesh.

There is a need to further improve packaging devices comprising a flexible porous membrane through which the product may be picked-up and which is not a follower.

Object and summary of the invention According to one aspect, the invention provides a device for packaging a product, in particular a cosmetic product or a care product, comprising:

- a cup member defining a reservoir of the product,

- a mesh, which is preferably elastically deformable, through which the product is picked-up,

characterized in that it comprises:

- a support piece onto which the mesh is attached in a peripheral fixing zone, the support piece being immobilized relative to the cup member during dispensing of the product, and

- a stretching member configured for stretching the mesh by pressing on it at at least one location that is radially inside said peripheral fixing zone.

The mesh attached to the support piece is not a follower.

It should also be noted that the mesh and support piece are attached to one another before assembling of the device.

Advantageously, the support piece is immobilized otherwise than by snap fastening of the support piece to the cup member.

The expression“otherwise than by snap-fastening” means that the support piece is immobilized relative to the cup member by friction, by bonding, by welding or by at least one axial locking element.

In such case, there is no need to provide the support piece and cup member with corresponding reliefs for snap-fastening. The tension of the mesh can be more easily adjusted with less risk of under- stretching or overstretching the mesh. Manufacturing tolerances may be higher.

Moreover, it offers more possibilities for performing a seal at the junction of the various elements if necessary.

The support piece is preferably immobilized on at least one location of the support piece that is not in contact with the mesh. It permits a good fixation of the support piece, as there is no contact between the support piece and the mesh at said at least one location of the fixation.

During the assembling of the device, the support piece may be inserted on the cup member until it comes into abutment with a surface of the cup member or until the desired position is reached, depending the embodiments. The insertion of the support piece may generate friction forces that immobilize the support piece in the cup member. The mesh may or may not be pressed between the support piece and the cup member, depending the embodiments. If it is pressed, it may help to immobilize the support piece in the cup member. The support piece may be inserted into the cup member until abutment of the support piece against an upper edge of a skirt of the cup member. The support piece may comprise one or more ribs that contribute to generate frictional forces against the cup member. The one or more ribs preferably abut against surface(s) of the cup member that are cylindrical. There is advantageously no engagement of the rib(s) with corresponding groove(s) of the cup member.

The invention allows to adjust the tension or stretching of the mesh during assembling of the device.

The support piece is advantageously made in a rigid polymer material, for example a rigid thermoplastic material.

In case of the absence of snap-fastening of the support piece in the cup member, this allows to use rigid materials to make the support piece and the cup member, as the support piece or the cup member does not need to deform to a large extent when the support piece is inserted in the cup member. The absence of snap-fastening may also facilitate the molding of the support piece and cup member, as there is no need to make snap-fastening grooves.

The mesh is advantageously sufficiently elastically deformable so as to be able to come into contact with a bottom of the reservoir when the product in the reservoir has been used up. After the device is assembled, the mesh is not stretched up to the limit of elasticity. The device according to the invention enables to obtain a good restitution rate of the product. The restitution rate may be for example greater than 80%, better greater than 85%.

The stretching member is configured for stretching the mesh when the device is assembled. This stretching of the mesh remains during use of the device. The stretching of the mesh thanks to the stretching member does not exist before the physical contact between the mesh and the stretching member. The mesh attached to the support piece may be flat before being in contact with the stretching member. The support piece does not comprise the stretching member. The stretching member may be part of an internal peripheral skirt. In such case, the stretching member is for example at least partially constituted by an upper end of the internal peripheral skirt. In a variant, the stretching member is constituted by a lower end of the internal peripheral skirt, depending on the orientation of the skirt, upward or downward.

In a particular embodiment, the internal peripheral skirt has a constant height. In a variant, the internal peripheral skirt has a varying height.

The support piece may be immobilized in at least one location of the support piece that is radially outside the peripheral fixing zone.

The support piece may be immobilized by contact with an external peripheral skirt, for example by friction, by bonding or by welding with such external peripheral skirt.

When the device comprises an internal peripheral skirt and an external peripheral skirt, the support piece may be at least partially sandwiched between the internal peripheral skirt and the external peripheral skirt. In such a case, the support piece may be immobilized by friction, by bonding or by welding.

The internal peripheral skirt and the external peripheral skirt, when present, are arranged in a concentric manner.

The support piece may be prevented from axially moving by at least one axial locking element. The at least one axial locking element may axially cover the support piece so as to prevent it from axially moving.

The cup member may comprise the stretching member.

The device may comprise a covering part cooperating with the cup member. In such case, the covering part may comprise the stretching member.

When the device comprises an external peripheral skirt, the latter may be part of the cup member or part of the covering part, if any.

In a particular embodiment, the device has no covering part.

The support piece may comprise a circumferential rib whose contact with another part of the device participates to the immobilization of the support piece.

The mesh is advantageously welded to the support piece in the peripheral fixing zone, for example by ultrasounds or high frequency welding.

The support piece comprises for example a ring, the peripheral fixing zone being preferably at a lower end of the ring. The peripheral fixing zone may otherwise be at an upper end of the ring. The support piece advantageously comprises a single skirt ring. This means that it has not two or more concentric skirts.

In an embodiment, the support piece comprises an external edge extending radially outwardly from the remainder of the support piece, in particular from an upper end of the ring. The external edge preferably rests on an element, for example on an upper end thereto, participating to the immobilization of the support piece.

The support piece may comprise an internal edge extending radially inwardly from the remainder of the support piece, said internal edge resting for example on the stretching member, a portion of the mesh being sandwiched between the internal edge and the stretching member.

The device or part of the device may be a refill. In such case, the refill may be packaged individually, for example in a sealed bag or box.

In one particular embodiment, one of the support piece and the cup member comprises at least one first partition wall, and the other of the support piece and the cup member comprises at least two second partition walls surrounding the first separation wall such that the mesh is enclosed between the at least one first partition wall and each of the at least two second partition walls. This embodiment permits creating compartments of products in the cup member.

The peripheral fixing zone delimitates for example a zone having a shape chosen among a circular shape, an oval shape, and a polygonal shape such as a rectangular or a square shape.

The peripheral fixing zone may have an annular shape.

The mesh may be a textile mesh and may comprise a woven, a non-woven or a knitted fabric. The mesh may be a foam membrane or another non-textile mesh such as a perforated plastic film for example.

The mesh is permeable so that the product can be picked up through it.

The mesh comprises a lower surface that is oriented towards the product contained in the reservoir and an upper surface away from the product contained in the reservoir.

The maximum thickness between the lower surface and the upper surface of the mesh is the thickness of the mesh. The thickness of the mesh may be between 0.4 and 5 mm. The area of the upper surface of the mesh may lie between 180 mm ² and 3800 mm ² . Such an area of the upper surface and such a thickness of the mesh make it possible to have a large surface for the user to access the product, while minimizing the quantity of textile material that is necessary and the quantity of product that remains trapped in the mesh at the end of use.

Depending on the degree of initial filling of the cup member, the product contained in the reservoir may or may not be in contact with the lower surface of the mesh when no pressure is applied to the latter by the user.

Preferably, the mesh can conform to the surface of the product contained in the reservoir while said product is being picked up.

The upper surface of the mesh may be substantially flat in its part through which the product passes during use. The lower surface of the mesh may be substantially flat in its part through which the product passes during use. The areas of the upper and lower surfaces of the mesh may be the same or different.

The thickness of the mesh may be substantially constant in its part through which the product passes during use.

The support piece may be fixed to the upper surface of the mesh. Alternatively, the support piece is fixed to the lower surface of the mesh.

The bottom of the reservoir may have a substantially flat shape or a concave shape towards the mesh. The bottom of the reservoir may have a paraboloidal, ellipsoidal or spherical shape. The bottom of the reservoir may be situated roughly at the same level as the lower part of the device.

The cosmetic product is advantageously one of a foundation, a concealer product, a complexion corrector and a care product.

The product may be either in a liquid, pasty or free powder form.

The product may be fluid. The viscosity of the product may be between 40 and 90 UD (Deviation Unit), preferably between 55 and 80 UD, or between 366 and 569 cP (centiPoises), or between 0.37 and 0.57 Pa.s.

This viscosity is measured at 25°C with a Rheomat 180 (Lamy) equipped with an MS-R2 spindle, selected for a low to medium viscosity of the product, which rotates at a speed of 200 revolutions per minute. The measurement is taken after a rotation time of 10 minutes. The viscosity measurements are taken at the latest one week after manufacture. Such a viscosity makes it possible to improve the taking of the product from the upper surface of the mesh and to avoid product flowing during use.

The device may comprise a protective lid which covers the mesh when the product is not being picked up. The protective lid can be fixed by friction, screw-fastening, bayonet locking or snap-fastening. In a variant, the protective lid can be connected in an articulated manner or by a sliding connection.

The product can be taken from the upper surface of the mesh with the aid of an applicator. This applicator may comprise or be constituted of an applicator member such as a foam, a brush, a sponge, a nonwoven, or a flocked end piece.

In a variant, the product is picked up with a finger, by passing the latter over the mesh.

It is possible for the device not to have an applicator accommodated between the protective lid and the mesh. This makes it possible to simplify manufacture compared with devices in which an applicator is incorporated, and to give the user greater freedom of choice for applying the product.

In one variant, the device comprises an applicator so as to provide the user with a complete system.

The device may comprise a mirror, in particular accommodated in the protective lid.

The device is deprived of any wiper member through which the applicator is extracted.

The device may comprise no bellow, in particular in the cup member.

The cup member may comprise a rigid body. The rigid body may be produced by molding a thermoplastic material, with a cavity defining the space holding the product and constituting the reservoir. The cup member is not a flexible sheet.

The cup member may comprise the internal peripheral skirt and the external peripheral skirt, arranged in a concentric manner, the support piece being inserted between them.

The support piece may be supported by an upper edge of an internal peripheral skirt or external peripheral skirt that is part of the cup member, the support piece being caught between the cup member and a retention piece. When the cup member comprises the internal peripheral skirt and the external peripheral skirt, arranged in a concentric manner, the support piece may rest against the bottom of a cylindrical space between the two skirts.

There may be one single piece that comprises the stretching member and a retention by radial clamping.

Method for assembling a device

A further subject of the invention is a method for assembling a device as defined above, comprising:

- filling the cup member with product,

- providing the support piece with the attached mesh,

- bringing into contact the mesh with the stretching member and pressing on the mesh with the stretching member so as to stretch the mesh,

- immobilizing the support piece relative to the cup member.

Makeup method

A further subject of the invention is a makeup method comprising the steps of:

- loading an applicator with product by using a device as defined above, and

- applying the product to a region to be treated of human keratin materials.

The applicator may be loaded without moving the applicator other than by moving it into contact with and then away from the mesh, this causing the product to be deposited on the applicator.

In a variant, at the time that product is picked up, the user can turn the applicator and/or move it in translation in contact with the mesh.

The product may be grasped by friction or by tapping the applicator or the finger on the mesh.

Detailed description of the drawings

In the rest of the description, identical elements or elements having equivalent functions bear the same reference signs. Their description is not repeated for each of the figures, only the main differences between the embodiments being highlighted.

Figures 1 to 4 show an embodiment of a device 1 for packaging a product according to the invention. The device 1 is assembled according to an axis X. The device 1 comprises a cup member 2 defining a reservoir 3 of the product. In figures 1 to 4, the reservoir 3 is shown empty. The reservoir 3 is defined by an internal peripheral skirt 4 of cylindrical shape and a bottom 5 that is partially flat, as shown. In this example, the diameter of the internal peripheral skirt 4 is greater than the height of the internal peripheral skirt 4.

The device 1 also comprises a mesh 6 which is elastically deformable, permeable, through which the product is to be picked-up. In this example, the mesh 6 is made of a woven fabric, but it could be made of a non- woven or knitted fabric or of another non-textile material, for example a foam, without departing from the scope of the invention.

The device 1 also comprises a support piece 10 onto which the mesh 6 is attached in a peripheral fixing zone 12. The support piece 10 comprises a ring 15 of cylindrical shape, in this example a single skirt ring. In this example, the mesh 6 is welded to the support piece 10. Still in this example, the peripheral fixing zone 12 is constituted by a lower end of the ring 15.

The device 1 comprises a stretching member 16 configured for stretching the mesh 6 by pressing on it at at least one location that is radially inside said peripheral fixing zone 12. In this example, the stretching member 16 is part of the internal peripheral skirt 4 of the cup member 2, being constituted by an upper end thereof. In this example, the internal peripheral skirt 4 has a constant height.

The support piece 10 is immobilized relative to the cup member 2 otherwise than by snap-fastening. The support piece 10 is partially immobilized by friction contact to another piece of the device at a location 20 that is, in this example, radially outside said peripheral fixing zone 12. In this embodiment, the cup member 2 comprises an external peripheral skirt 25 that is radially external and parallel to the internal peripheral skirt 4. There is an annular space 26 between the internal peripheral skirt 4 and the external peripheral skirt 25. In this example, the support piece 10 is immobilized relative to the cup member 2 by friction.

The two concentric peripheral skirts of the cup member 2 constituted by the internal peripheral skirt 4 and the external peripheral skirt 25 are linked at a lower end of the cup member 2 by a wall 27 that is flat and has a lower surface that is aligned with a lower surface of the bottom 5 of the reservoir 3. The wall 27 also extends radially outwardly relative to the external peripheral skirt 25, having an external edge 28. The skirts 4 and 25 are integral with the cup member.

The ring 15 of the support piece 10 comprises a circumferential rib 29 being in contact at the location 20 with the external peripheral skirt 25. The circumferential rib 29 extends on the radially external surface 30 of the ring 15, substantially in a middle part thereof.

The ring 15 of the support piece 10 also comprises a radially internal rib 31 extending on a radially internal surface 32 of the ring 15, at an upper end thereof. The support piece 10 comprises an external edge 33 extending radially outwardly from the remainder of the support piece 10, in this example from an upper end of the ring 15.

Before the assembling, the mesh 6 attached to the support piece 10 is flat as shown in figure 3.

During the assembling of the device according to axis X, the support piece 10 is assembled to the cup member 2 so that the stretching member 16 presses on the mesh 6 at one annular location 34 that is radially inside the peripheral fixing zone 12 so as to stretch the mesh 6, as shown in figure 4. The mesh 6 is deformed. Then, the mesh 6 comprises the welded outer zone 35, a tubular shaped zone 36 and a flat circular inner zone 37. The outer zone 35 corresponds to the peripheral fixing zone 12. The tubular shaped zone 36 is between the peripheral fixing zone 12 and the annular location 34. The inner zone 37 is the zone of the mesh 6 that is inside the annular location 34. This inner zone 37 is the zone of the mesh 6 through which the product is to be picked up. In this example, the inner zone 37 is circular in shape but it could be square-shaped, rectangular- shaped, or have another shape without departing from the scope of the invention.

When the device 1 is assembled, the support piece 10 is at least partially sandwiched between the internal peripheral skirt 4 and the external peripheral skirt 25. The presence of the ribs 29 and 31 serves to retain by friction the support piece 10 and the mesh 6 in the device 1. The support piece 10 is not movable within the device 1, once the latter is assembled.

The outer edge 33 rests on the upper end 40 of the external peripheral skirt 25 and acts as an abutment. Thus, the external edge 33 rests on the upper end 40 of the external peripheral skirt 25.

In addition to the cup member 2, the support piece 10 and the mesh 6, the device 1 may also comprise other parts. In this example, the device 1 comprises a case 50 having a substantially cylindrical opening 51 for receiving the cup member 2 and the support piece 10 attached to the mesh 6 as shown in figure 1.

The case 50 comprises part of a hinge 52 for receiving an articulated protective lid, not shown in the figures. The case 50 also comprises, in this example, a trim portion 53, a peripheral skirt 54 forming at least part of the delimitation of the cylindrical opening 51. Once the device 1 is assembled, the lower end of the peripheral skirt 54 rests on the external edge 28 of the cup member 2, which acts as an abutment. At least part of the outer surface 55 of the external peripheral skirt 25 is in contact with the internal surface 56 of the peripheral skirt 54. In this example, the outer surface 55 of the external peripheral skirt 25 comprises an upper circumferential rib 57 and a lower circumferential rib 58 to be in contact with the internal surface 56 of the peripheral skirt 54. Still in this example, the upper circumferential rib 57 is less high than the lower circumferential rib 58, as the peripheral skirt 54 has not a constant thickness but becomes thicker from the lower end towards the upper end.

The case 50 comprises a circumferential lip 60 at an upper end of the peripheral skirt 54. The circumferential lip 60 extends above and radially covers the support piece 10 and the annular location 34 until a peripheral portion of the inner zone 37 of the mesh 6. The circumferential lip 60 may act as an axial locking element for the support piece 10. In this example, an annular rib 61 at an upper end of the support piece 10 acts as an abutment of the circumferential lip 60. The lip 60 has a substantially flat shape outwardly the zone of contact with the support piece 10 and a converging shape inwardly the zone of contact with the support piece 10.

In a variant, the case 50 includes the support piece 10 attached to the mesh 6.

The zones of contact between the different elements of the device 1 allow to obtain the water tightness of the device 1.

The device 1 may be a refill. In such case, the refill may be packaged individually, for example in a sealed bag or box.

In the embodiment shown in figures 5 to 9, the bottom 5 of the reservoir 3 is round shaped. In this embodiment, the internal peripheral skirt 4 is less high than the external peripheral skirt 25 which also comprises an external peripheral edge 70. Still in this embodiment, the wall 27 linking from underneath the external peripheral skirt 25 and the internal peripheral skirt 4 is flat and has no edge 28. A great part of the bottom 5 of the reservoir 3 is under the lower level of the wall 27, as shown. The support piece 10 has a ring 15 with the outer edge 33 on an upper end thereof, the ring 15 being a single skirt ring. The support piece 10 has a circumferential inner rib 72.

In figure 5, the reservoir 3 is empty. In figure 6, the reservoir 3 of the cup member 2 is filled with a cosmetic product P which is a foundation in this example. The filling level 71 does not exceed the upper end of the internal peripheral skirt 4.

In figure 7, the support piece 10 attached to the mesh 6 is shown above the cup member 2 before assembling.

In figures 8 and 9, the support piece 10 and mesh 6 have been assembled to the cup member 2. The lower end of the ring 15 corresponding to the peripheral fixing zone 12 rests on the wall 27, in this example, which acts as an abutment. The circumferential inner rib 72 is in contact with an outer surface of the internal peripheral skirt 4. At least part of the external surface of the ring 15 is in contact with the inwardly radial surface of the external peripheral skirt 25 at the location 20 of contact. The support piece 10 is retained by friction in this example.

The product P may be picked up by a user, using an applicator or a finger pressing on the upper surface 73 of the mesh 6 in the inner zone 37. The product P goes through the permeable mesh 6 and is picked up so as to be applied or to make up keratin materials such as the skin of the user or another person.

Figures 10 and 11 show another embodiment of the invention.

In figure 10, the support piece 10 fixed to the mesh 6 is shown alone. The support piece 10 consists of a small ring 15 with no outer edge.

Once the support piece 10 together with the mesh 6 is assembled to the cup member 2, as shown in figure 11, the support piece 10 is in contact with the bottom end of the cylindrical space 26 and only occupies the lower part thereof.

In the embodiment shown in figures 12 and 13, the device 1 comprises a covering part 75. The covering part 75 comprises the inner peripheral skirt 4 whereas the cup member 2 only comprises the external peripheral skirt 25. The covering part 75 has a covering wall 77. The internal peripheral skirt 4 is attached to the remainder of the covering part 75 by a circumferential wall 76 that extends perpendicularly to the axis X from the covering wall 77 towards the inner part of the device 1. The internal peripheral skirt 4 extends downwards from the circumferential wall 76.

In the examples of figures 1 to 11, the support piece 10 is attached to the upper surface 73 of the mesh 6 so that the support piece 10 extends above the mesh 6. In the example shown in figures 12 and 13, the support piece 10 is attached to the lower surface 79 of the mesh 6 so that the mesh 6 extends above the support piece 10.

The peripheral fixing zone 12 is not exactly at the periphery of the mesh 6 but slightly inside, at some distance of the periphery of the mesh, this periphery forming a zone of fixation of the mesh to the upper end of the external peripheral skirt 25. The outwardly radial surface of the external peripheral skirt 25 is provided with reliefs that can be coupled to corresponding reliefs of the covering wall 77 of the covering part 75 so as to snap-fasten the cup member 2 and the covering part 75.

In this example, the support piece 10 is retained by bonding to the inner surface of the external peripheral skirt 25 thanks to an adhesive composition at the location 20. It could otherwise be retained by welding or by radial clamping.

The circumferential wall 76 covers the upper surface of the mesh 6. The stretching member 16 is formed by the lower end of the internal peripheral skirt 4 supported by the circumferential wall 76. The circumferential wall 76 also forms an axial locking element for the support piece 10.

In the embodiment shown in figures 14 and 15, the cup member 2 has two concentric peripheral skirts among which the internal peripheral skirt 4. Outwardly, the cup member 2 comprises another peripheral skirt 80, having a height that is smaller than the one of the internal peripheral skirt 4. In this embodiment, the device 1 comprises a covering part 75. The covering wall 77 of the covering part 75 is coupled to the peripheral skirt 80 by corresponding reliefs. The covering wall 77 presents inwardly a shoulder 81 which covers an upper end of the support piece 10. The support piece 10 is axially trapped between the shoulder 81 and the upper end of the peripheral skirt 80. The shoulder 81 covers axially the support piece 10, forming an axial locking element for the support piece 10. The support piece 10 is also sandwiched according to an axis that is perpendicular to the axis X, between the internal peripheral skirt 4 and the covering wall 77. A part of the tubular shaped zone 36 of the mesh 6 is sandwiched between the covering wall 77 above the shoulder 81 and the internal peripheral skirt 4 until the upper end thereof which constitutes the stretching member 16.

In the example shown in figures 16 and 17, the cup member 2 is quite similar to the one of figures 5 to 9. A difference is that the device 1 also comprises a covering support 85 for supporting the cup member 2. The cup member 2 also presents a lower peripheral skirt 86 extending under the wall 27, aligned with the external peripheral skirt 25. The lower peripheral skirt 86 has reliefs that are complementary to the ones of a corresponding peripheral wall 87 of the covering support 85 for snap-fastening them.

Still in this example, the support piece 10 comprises a circumferential lip 88 extending from the upper end of the support piece 10 on the opposite side of the outer edge 33. Once the device 1 is assembled, this circumferential lip 88 covers the annular location 34 above the mesh 6 and may act as an abutment. In this zone, the mesh 6 is thus sandwiched between the circumferential lip 88 and the stretching member 16 being the upper end of the internal peripheral skirt 4 of the cup member 2.

In the example of figures 18 and 19, the stretching member 16 is part of the covering part 75 that comprises a neck 90 of the device 1, having a wall 91 extending under the neck 90 and coupled to the cup member 2 by snap-fastening. The covering part 75 also participates to the immobilization of the support piece 10. The upper end of the cup member 2 extends between this wall 91 and the external peripheral skirt 25. The latter is part of the covering part 75, extending under the neck 90 and being in contact at the location 20 with the support piece 10 so as to immobilize it by friction. The external peripheral skirt 25 is linked by the wall 27 to the internal peripheral skirt 4 which is part of the covering part 75 too and comprises at an upper end the stretching member 16.

Figures 20 to 23 illustrate an embodiment wherein the internal peripheral skirt 4 has a varying height. The stretching member 16 is formed by the upper end of the internal peripheral skirt 4 so that the shape of the inner zone 37 of the mesh 4 is not flat after assembling. In this example, the peripheral fixing zone 12 is neither flat, having a shape similar to the one of the upper end of the internal peripheral skirt 4. Otherwise the cup member 2 and the support piece 10 are quite similar to the ones shown in figures 1 to 4.

In the embodiment shown in figures 24 to 27, one of the support piece 10 and the cup member 2, in this example the support piece 10, comprises a first partition wall 100, and the other of the support piece 10 and the cup member 2, in this example the cup member 2, comprises two second partition walls 101 and 102 surrounding the first separation wall 100 such that the mesh 6 is enclosed between the first partition wall 100 and each of the two second partition walls 101 and 102. The mesh 6 is stretched by the stretching member 16 at the periphery and also at the partition walls 100, 101 and 102, as shown in figure 26. The second partition walls 101 and 102 provides two compartments of product within the cup member 2, even if there is one mesh 6, one support piece 10 and one cup member 2.

The invention is not limited to the embodiments shown. There may be more than two compartments of product within the cup member 2.
