EP3687336B1 - Rechargeable packaging device for a cosmetic product - Google Patents

Description

The present invention relates to a refillable device for packaging a cosmetic product and to a removable container intended to be used in such a refillable device. The invention also relates to a cosmetic product refill and a method for replacing the removable container of such a device.

In the cosmetic field, in particular, users are particularly sensitive to the aesthetics of packaging devices. However, the cost of aesthetic packaging devices is high and increases the price of cosmetic products sold in this form commercially.

An idea emerged consisting of providing an aesthetic packaging device, including a separate container, less aesthetic, but whose packaging is less expensive. Preferably, the container is removable so that the packaging device can be recharged by replacing the removable container.

Requirement FR-A-2 995 199 describes for example a pot for a cosmetic product comprising a shell forming a neck delimiting an upper edge of the shell, and an insert containing the cosmetic product received in the shell. A cover can be screwed onto a thread made on the outer surface of the neck. However, in this document the insert is not intended to be replaced. Therefore, the main disadvantage of this pot is that it is not refillable.

To make such an insert removable, FR-A-2 745 276 suggests forming a small hole between the bottom of the shell and the housing receiving the insert, so that you can pass a thin object through it and push the insert from below.

However, depending on the material from which the insert is made, the operation aimed at pushing the insert from below can simply lead to deforming the insert, with the risk of cosmetic product splashing. In addition it is necessary to use a tool that can be inserted into the hole in the bottom of the hull.

Furthermore, application TWM365672 describes a pot comprising a shell, with a housing with a non-circular section, receiving a cosmetic product refill of complementary section to housing. A ring is screwed onto the shell, above the refill, leaving a threaded edge of the refill protruding from the ring. A cover is screwed onto this threaded edge.

The pot as described in TWM365672 is however not very aesthetic, a clearance existing between the ring and the threaded edge of the refill, to allow the passage of this threaded edge in the opening formed by the ring.

An aim of the invention is to propose a refillable cosmetic product packaging device which does not present at least some of the aforementioned drawbacks. In particular, the invention aims to provide a refillable packaging device whose removable container can easily be replaced, while ensuring satisfactory fixation of the removable container, particularly when the cover of the packaging device is closed.

• un contenant amovible contenant du produit cosmétique,
• une coque d'habillage définissant un logement de réception du contenant amovible, le logement de réception du contenant amovible débouchant au niveau d'un débouché dans la coque d'habillage, le contenant amovible étant fixé à la coque d'habillage par emboîtage élastique de reliefs complémentaires, le contenant amovible pouvant être retiré de la coque d'habillage de manière réversible,
• un couvercle apte à obturer le débouché du logement dans la coque d'habillage,

• a cover capable of closing the opening of the housing in the covering shell,

in which the cover is able to be fixed to the removable container so as to lock the elastic interlocking of the complementary reliefs.

Thus, advantageously, once the cover is fixed on the removable container, it is no longer possible to remove the removable container from the covering shell. This avoids any risk of untimely removal of the removable container, outside the covering shell.

Despite everything, it is still possible to replace the removable container, in particular by removing the cover before removing the removable container from the covering shell.

Advantageously, this removal of the removable container is reversible, that is to say that the removed removable container can again be fixed to the covering shell by elastic interlocking of complementary reliefs.

In the remainder of the description, identical elements or elements with identical function bear the same reference sign. For the sake of conciseness of this description, these elements are not described in detail in each example. Rather, only the differences between the embodiments are described in detail.

THE figures 1 to 8 illustrate a first example of a rechargeable cosmetic product packaging device 10 (hereinafter packaging device 10). This packaging device 10 essentially comprises a removable container 12 of cosmetic product, a covering shell 14 receiving the removable container 12, a cover 16 and a seal 18. The seal 18 aims to prevent the product from cosmetic contained in the removable container 12 does not dry out.

More precisely, the covering shell 14 defines a housing 20 intended to receive at least in part the removable container 12. The housing 20 opens at an outlet 22 in the covering shell 14. The covering shell 14 also forms an edge 24 around the outlet 22. The covering shell 14 is here shaped to allow the covering shell 14 to be placed in balance on a flat support. Such as illustrated, the covering shell 14 rests on such a flat support by a support zone 26 surrounding a bottom 28, set back relative to the support zone 26. Alternatively, the bottom 28 is not set back from the support zone 26 but, on the contrary, is part of this support zone 26. The support zone 26 is for example with a closed contour, in particular with a circular or elliptical contour, or any other shape. Alternatively, the support zone 26 is formed, as illustrated, by feet separated from the covering shell 14. The bottom 28 of the covering shell 14 possibly has a through hole 30, opening on the one hand onto the bottom 28, outside the covering shell 14, and, on the other hand, in the housing 20. The hole 30 advantageously allows the passage of a finger. To do this, the hole 30 may have a diameter of at least 10 mm, preferably at least 15 mm. According to an embodiment not shown, the flat bottom 28 of the covering shell 14 is covered at least partially by a label, the label being able or not to cover the hole 30. The label can for example carry any information relating to the brand of the product and/or its composition and/or its method of application and/or its possible expiry date.

Between the support zone 26 and the edge 24 of the outlet 22, the covering shell 14 essentially forms a lower part 32 of substantially parallelepiped exterior shape, and an upper part 34 of tubular shape, forming a neck. Of course, this shape of the covering shell 14 is not limiting, it being able to have substantially any shape, in particular any shape aimed at ensuring the aesthetics of the packaging device 10. A substantially circular groove 36 is made at the base of the neck 34 of the covering shell 14. A vertical notch 38 is also made in the neck 34 of the covering shell 14.

The covering shell 14 is preferably translucent, or even transparent. This gives the covering shell 14 and the packaging device 10 an aesthetic effect appreciated by users. The covering shell 14 can also be opaque.

The covering shell 14 can in particular be made from one of: glass, metal, ceramic, porcelain, crystal and plastic, in particular polymethyl methacrylate, polystyrene, polycarbonate, polyethylene terephthalate, ionomer resin such as ethylene vinyl copolymer known as trade name for Surlyn ^® , natural stone, synthetic stone, ceramic, porcelain, wood and urea formalin.

Furthermore, the removable container 12 has a bottom 40, an orifice 42 and a side wall 44 between the bottom 40 and the orifice 42. The bottom 40 of the removable container 12 here has the shape of a nipple, substantially flat. Consequently, when the removable container 12 is placed with the bottom 40 on a flat support, the removable container 12 is in unstable equilibrium. This makes it more difficult to use the removable container 12 when it is not mounted in the covering shell 14. This is particularly true in the case where the cosmetic product contained in the removable container is in powder form, liquid, cream, which tend to flow out of the removable container 12 when it is not kept vertical.

Furthermore, the side wall 44 of the removable container 12 has, according to the example of figures 1 to 3 , a substantially hemispherical shape, flared towards the orifice 42. However, other shapes of the side wall 44 of the removable container 12 are possible. However, the side wall 44 of the removable container 12 preferably has a flared shape from the bottom 40 to the orifice 42, in order to facilitate access by the user to all of the cosmetic product contained in the container. removable container 12.

The side wall 44 of the removable container 12 here forms a rim 46 around the orifice 42. In other words, the side wall 44 is folded around the orifice 42. The rim 46 is shaped to receive the neck 34 of the trim shell 14. In particular, the width of this rim 46 is substantially equal to the width of the neck 34 of the trim shell 14. Also, a fold 48 surrounding the rim 46 radially on the outside is of length substantially equal to the height of the neck 34 of the covering shell 14 added to the width of the groove 36 made at the base of the neck 34. On its radially external face, the fold 48 has a thread 50.

The fold 48 also has at least one tongue 52. In this case, the fold 48 has three tongues 52. The tongues 52 are here angularly evenly distributed on the fold 48. The tongues 52 are arranged under the thread 50, i.e. that is to say between the thread 50 and the free end 54 of the fold 48. The tongues 52 are cut out in the fold 48. In other words, the tongues 52 are separated from the rest of the fold 48 by two spaces, arranged on either side and on the other of each of the tabs 52. At its end lower and on its radially inner face, each tongue 52 has a bead 56, of section substantially complementary to the section of the groove 36 at the base of the neck of the covering shell 14.

Finally, a stop 58 is provided on the radially internal face of the fold 48. The stop 58 is produced in the form of a relief projecting from the radially internal face of the fold 48, extending mainly in the direction of the fold. 'axis X, median of the rechargeable cosmetic product packaging device 10. The stop 58 is shaped to be received in the notch 38 formed in the neck 34 of the covering shell 14. This stop 58 can thus allow indexing of the removable container 12 on the covering shell 14. in other words, the stop 58 cooperating with the notch 38, makes it possible to fix the relative angular position of the removable container 12 relative to the covering shell 14, around the axis X.

The removable container 12 may in particular be made of aluminum, aluminum alloy, steel, glass, plastic, ceramic, porcelain, cardboard, in particular varnished cardboard or multilayer cardboard complexed with other materials such as metal sheets or plastic sheets. Depending on the materials used, producing the removable container is more or less easy and therefore expensive. More noble materials such as porcelain, ceramic or glass can be chosen to ensure an aesthetic and quality effect appreciated and sought after by users. The use of these materials can also contribute to the aesthetic effect of the packaging device 10, in particular when the covering shell 14 is translucent or transparent.

The removable container 12 may in particular comprise cosmetic product in the form of cream, paste, powder, gel, liquid or monobloc solid.

Finally, the cover 16 is able to close the orifice 42 of the removable container 12.

The cover 16 has an external wall 60 which can take any desired shape, in particular in order to obtain an aesthetic effect of the packaging device 10.

An internal wall 62 of the cover 16 defines an opening cavity. This internal wall 62 is provided with a screw thread 64. The screw thread 64 allows, by cooperation with the thread 50 on the fold 48 of the removable container 12, to fix the cover 16 on the removable container 12. Preferably, the cover 16 and the removable container 12 are shaped to grip the seal 18, when the cover 16 is fixed on the removable container 12. In particular, as is for example visible in the figure 5 , when the lid 16 is fixed on the removable container 12, the seal 18 is clamped between the bottom 66 of the lid and the rim 46 of the removable container 12, in particular the top of the rim 46 of the removable container 12.

The cover 16 can be translucent, even transparent, or on the contrary opaque.

The cover 16 is for example made of one of wood, a ceramic material, metal, porcelain, a rigid foam for example polyurethane type, natural stone, synthetic stone, mixed stone powder to a binder, transformed by injection, leather, glass, crystal, plastic in particular thermosetting plastic, such as urea formaldehyde, or thermoplastic plastic, and/or in particular frosted and/or varnished and/or painted plastic and/or metallized and/or galvanized and/or provided with visual effects, natural fabric, or synthetic fabric, or any other known material for making a cover.

The packaging device 10 can be sold fully assembled. Alternatively, the packaging device 10 is sold as a kit. In this case, the assembly of such a conditioning device 10 can be carried out as follows.

First of all, as illustrated by the figures 4 to 6 , the removable container 12 is inserted partially into the housing 20 formed by the covering shell 14. Due to this partial insertion, the beads 56 at the end of the tongues 52 of the removable container 12 are not fitted elastically into the groove 36 complementary made at the base of the neck 34 of the covering shell 14. In this position, the tongues 52 are elastically deformed. As illustrated in Figure 6 , the beads 56 can be arranged substantially opposite the groove 36 at the base of the neck 34 of the covering shell 14. Thus, preferably, the insertion of the removable container 12 into the housing 20 is carried out over a length sufficiently large so that the stop 58 on the internal face of the fold 48 is received in the notch 38 formed in the neck 34 of the covering shell 14.

Then, the removable container 12 is pushed towards the covering shell 14 so that the beads 56 are received in the groove 36, as illustrated in Figure 6 . This allows the elastic nesting (or “clipping”) of the removable container 12 on the covering shell 14. More particularly, it allows the fixing of the container removable 12 on the covering shell by elastic fitting of the beads 56 of the tongues 52 of the removable container 12 in the complementary groove 36, formed at the base of the neck 34 of the covering shell 14.

Preferably, in this position, the tongues 52 are not elastically deformed.

Finally, as illustrated in Figure 7 , we screw the cover 16 onto the removable container 12. Screwing the cover 16 onto the removable container makes it possible to lock the elastic fitting of the removable container 12 onto the covering shell. Indeed, as is particularly visible on the figures 7 and 8 , the cover 16, screwed onto the removable container 12, prevents any elastic deformation of the tongues 52, aimed at removing the beads 56 of the tongues 52 out of the groove 36 at the base of the neck 34 of the covering shell 14. In the position of the cover 16, screwed onto the removable container 14, the fold 48 and the tabs 52 in particular are sandwiched, preferably substantially without play, between the internal wall 62 of the cover 16 and the neck 34 of the covering shell 14.

It should be noted here that screwing the cover 60 onto the removable container 12 is made easier because the stop 58 is received in the notch 38 in the neck 34 of the removable container. This stop 58 thus limits the relative rotation of the removable container 12 relative to the covering shell 14. Also, by holding the covering shell 14 with one hand, the cover 16 can be screwed with the other hand, onto the removable container 12.

It is particularly interesting that the cover 16 is fixed on the removable container 12. In fact, the fixing reliefs (here a screw thread, but other means of fixing can be imagined, in particular elastic nesting reliefs , for example) may contain cosmetic product deposits. By replacing the removable container 12 and/or the cover 16, we get rid of these cosmetic product deposits. In addition, this makes it possible to market refills composed of a removable container 12 and a cover 16, which can make it possible to regularly change the shape of the cover 16 and therefore modify the shape of the refillable cosmetic product packaging device 10. The shape and/or color of the lid can also be modified depending on the cosmetic product in the associated removable container 12 to form a cosmetic product refill.

The removable container 12 can be provided with a waterproof cover. This waterproof cover can be removed from the removable container 12 before or after its insertion into the covering shell 14. The cover, possibly provided with a seal, ensures the sealing of the removable container 12 before it is opened. Advantageously, the cover cannot be put back in place on the removable container 12 so that the cosmetic product cannot be stored, after opening, except in the packaging device 10. In fact, only the device packaging 10 makes it possible to close the removable container 12, open, by means of the cover 16, ensuring a suitable seal, by means of the seal 18.

Once all of the contents of the removable container 12 have been used, the user can remove the removable container 12 from the packaging device 10. To remove the removable container 12, a user must first remove the cover 16. Only then, the user can remove the removable container 12. The removal of the removable container 12 from the covering shell 14 can for example be carried out by pushing on the removable container 12 through the opening 30 in the bottom 28 of the covering shell 14 or, preferably by pulling on the removable container or on one of the pastes 52 to bring out the corresponding bead 56 from the groove 36.

Interestingly, the removal of the removable container 12 from the covering shell 14 can be carried out in a reversible manner. In other words, this removal is carried out without damage to the removable container 12 or to the covering shell 14. In particular, the tabs 52 are neither plastically deformed, which would prevent them from returning to their initial shape, nor torn. These tabs 52 can thus once again allow the beads 56 which they carry in the groove 36 to be fitted together elastically. The removable container 12 can thus be reused or assembled and disassembled several times on a covering shell.

Once the old removable container 12 has been removed, the user can then insert a new removable container 12, operating as described previously.

THE figures 9 to 13 illustrate a variant 100 of the rechargeable cosmetic product packaging device 10 according to the first example described.

In this variant, the tabs 52 on the fold 48 of the removable container 12 form not only a bead 56 received in the groove 36 at the base of the neck 34 of the covering shell, but also a bead 102. This bead 102 is oriented radially towards the outside of the removable container 12. The bead 102 allows, by cooperation with the screw thread 64 inside the cover, to grip the tabs 52 even more closely between the cover 18 and the neck 34 of the shell d cladding 14, as is particularly visible on the Figure 13 . Indeed, this bead 102 oriented radially towards the outside limits or even eliminates any play between the cover 16 and the tab 52, at the level of the free end 54 of the tab 52. This reduced play is particularly visible by comparison of the figures 7 And 12 .

Finally, the figures 14 to 20 illustrate a third example 200 of a rechargeable cosmetic product packaging device.

According to this example, the removable container 12 is not fixed directly to the covering shell 14. The removable container 12 is fixed to the covering shell.

Here, by "directly fixed on", we mean that the fixing is carried out at at least one surface of the removable container and a surface of the covering shell 14 in contact with each other. In other words, the removable container 12 is directly connected to the covering shell 14. In particular, in the case of an elastic nesting, "directly fixed on" means that an elastic nesting relief is produced by the removable container 12 while the other elastic nesting relief is produced by the covering shell 14.

“Fixed to” means more broadly that although the removable container 12 is made integral with the covering shell 14, the removable container 12 may not be directly connected to the covering shell 14. In particular the fixing may not be carried out at the surfaces in contact with the covering shell and the removable container. There may, however, be contact between the removable container 12 and the covering shell 14, but this contact is not such as to secure the removable container 12 and the covering shell 14. This connection can then be achieved indirectly. , by means of one or even several intermediate parts.

Thus, in the rechargeable cosmetic product packaging device 200 according to the figures 13 to 20 , the removable container 12 is fixed to the covering shell 14 via a ring 202 (or “fret”). Here, the ring 202 forms a first crown 204, of large diameter, a second crown 206 of small diameter, and a portion 208 in the form of a ring which connects together the first and second crowns 204, 206. The second crown 206 is extends over significantly the entire height of the ring 202. On the contrary, the first crown 204 extends over only a portion of the height of the ring 202. In particular, the first crown 204 extends over substantially half the height of the ring 202. The ring 202 thus has an “h” section.

The first crown 204 forms on its radially internal face reliefs 210 intended to be received in complementary housings 212, made in the neck 34 of the covering shell 14. It should be noted that here, the covering shell 14 is devoid of circular groove 36 at the base of the neck 34. The housings 212 can in particular be formed by flats 214 or recesses 216 in the radially external surface of the neck 34. The reliefs 210 on the first crown 204 can in particular take the form of tongues extending mainly in a radial direction.

The ring 202 can be shaped to be mounted tight on the neck 34 of the trim shell. The radial distance between the first and second crowns 204, 206 is then equal to or even substantially less than the thickness of the neck 34 of the covering shell 14. The height of the neck 34 is substantially equal to the height of the first crown 204 of such that when the ring is mounted tight on the neck 33, the top of the neck 34 rests on the ring-shaped portion 208 of the ring, while the free end of the first crown 204 rests on the part of the covering shell 34 at the base of the neck 34.

The second crown 206 forms, on a lower portion intended to be oriented towards the covering shell 14, reliefs 218. As is more particularly visible on the Figure 14 , these reliefs 218 have a substantially half-disc shape, the base of which is oriented downwards.

The second crown 206 also forms, on a high portion intended to be oriented opposite the covering shell 14, tabs 220. These tabs 220 have a bead 222 oriented radially inwards. The tabs 220 can be made substantially identical to the tabs 52 of the first and second examples described above.

Finally, in the example of realization of figures 14 to 20 , the removable container 12 has on its radially outer surface housings 224 of shape substantially complementary to the reliefs 218 made on the radially inner wall of the lower portion of the first crown 204.

The removable container 12 also has on its radially external surface a circular groove 226 and, between the circular groove 226 and a free end 228 of its lateral surface 44, a screw thread 50 intended to cooperate with a screw thread 64 complementary to cover 16.

The assembly of the rechargeable cosmetic product packaging device 200 according to the Figure 14 can be done as follows.

First of all, the ring 202 is mounted on the neck 34 of the covering shell 14. This assembly can be carried out by force insertion of the neck 34 of the covering shell 14 into the space delimited by the first and second crowns 204, 206 and the ring-shaped portion 208. During this insertion, the reliefs 210 made on the radially internal face of the first crown 204 are inserted into the housings 212 made in the radially external surface of the neck 34 of the covering shell 14. Thus, the relative rotation of the ring 202 relative to the covering shell is limited or even prevented. The ring 202 is advantageously immovable relative to the covering shell 14.

The removable container 12 is then inserted into the housing 20 formed by the covering shell 14 as illustrated in Figure 15 . As we can see in this Figure 15 , in this position the beads 222 of the tabs 220 formed by the ring 202 are not yet received in the groove 226 formed on the radially external surface of the side wall 44 of the removable container 12. In this position, the tabs 220 are elastically deformed .

We then push the removable container 12, to allow the elastic nesting of the removable container 12 on the ring 202. In other words, we push the removable container 12 so that the beads 222 of the tabs 220 formed on the ring 202 are received in the groove 226 on the side wall 44 of the removable container 12. Concomitantly, the reliefs 218 in the form of a half-disc of the radially internal face of the second crown 206 of the ring 202, are received in the complementary housings 224 formed in the side wall 44 of the removable container 12. Consequently, the relative rotation of the removable container 12 relative to the ring 202 is limited, or even prevented. It is also possible to allow indexing of the removable container 12 relative to the ring, in particular by implementing different housings 224 and reliefs 218.

Finally, the cover 16 is screwed onto the removable container 12. The ring 202 being already secured in rotation to the covering shell 14, it is thus more easily possible to screw the cover 16 onto the removable container 12, while keeping the shell stationary. dressing 14.

Once the cover 16 is screwed onto the removable container 12, the elastic fitting of the tabs 220 on the removable container 12 is locked. Indeed, as is particularly visible on the Figure 20 , in this position, the tabs 220 are sandwiched between the cover 16 and the removable container 12, preferably with limited play or no play at all. The elastic deformation of the tabs 220 necessary for dismantling the removable container 12 is thus prevented.

Disassembly of the removable container 12 from the covering shell 14 is however possible, after removal of the cover 16. Preferably, this removal of the removable container 12 from the covering shell 14 is possible in a reversible manner, it is that is to say in such a way that the removable container can again be fitted elastically onto a covering shell.

THE figures 21 to 24 illustrate a fourth example 300 of a cosmetic product packaging device.

In this fourth example 300, the removable container 12 comprises two portions 302, 304, one of which has dimensions greater than the outlet 22 of the housing 20 in the covering shell 14. More precisely, the removable container 12 comprises a lower portion 302, of cross section greater than the area of the outlet 22 of the housing 20 in the covering shell 14, and an upper portion 304, of cross section substantially identical to the area of the outlet 22 of the housing 20 in the shell of covering 14.

The lower portion 302 forms a cosmetic product reservoir. This lower portion 302 can be of any shape, adapted to the housing 20 in the covering shell 14. The lower part 302 here forms a shoulder 306 near the upper portion 304. The upper portion 304 of the removable container 12 has substantially the shape of a neck, provided with a circular groove 308 surrounded by two circular beads 310, 312, and a thread 50 in the vicinity of the outlet of the removable container 12.

To allow the insertion of the removable container 12 at least partially into the housing 20 in the covering shell 14, the covering shell 14 is provided with an opening 314, opposite the outlet 22 of the housing 20 in the housing shell 14. covering, of cross section adapted to the cross section of the lower portion 302 of the removable container 12. This opening 314 is in particular of cross section greater than the cross section of the outlet 22.

Around the outlet 22 of the housing 20 in the covering shell 14, the covering shell 14 forms a rim 316 with elastically deformable legs 318. In this case, the rim 316 comprises four tabs 318, angularly evenly distributed around the outlet 22 of the housing 20 in the covering shell 14. The tabs 318 have a bead 320 oriented radially inwards. The bead 320 has a section substantially complementary to the section of the groove 308 in the upper portion 304 of the removable container 12.

Finally, in the example illustrated, the cover 16 is formed from the assembly of an external shell 322 and an internal shell 324. The external shell 322 defines the external wall 60 of the cover 16, while the internal shell 324 defines the internal wall 62 of the cover 16. In particular, the internal shell 324 defines a screw thread 64 adapted to cooperate with the thread 50 on the removable container 12 to allow the cover 16 to be fixed on the removable container 12 by screwing.

This fourth embodiment 300 is thus distinguished from the embodiments described previously in that the removable container 12 is inserted into the covering shell 14 through an opening 314, opposite the outlet 22 of the housing 20 in the covering shell 14 , outlet 22 in the vicinity of which the removable container 12 is fixed to the covering shell 14. Here, the removable container 12 is fixed to the covering shell 14 by elastic interlocking of the tabs 318 of the covering shell 14, in the groove 308 on the removable container 12. As previously, and as is particularly visible on the Figure 24 , once the cover 16 fixed to the removable container 12, the tabs 318 of the covering shell are sandwiched between the internal shell 324 of the cover 16 and the removable container 12, limiting or even preventing the elastic deformation of the tabs 318. attachment of the removable container 12 to the covering shell 14 is thus locked. Removing the cover 16, however, allows the tabs 318 to be elastically deformed again, so as to remove the beads 320 on these legs 318, of the groove 308 in the removable container. The removable container 12 is thus released and can then be removed from the covering shell 14, through the opposite opening 314.

In this exemplary embodiment, it is possible to make the lower portion 302 of the removable container 12 of any desired shape, adapted to the housing 20 in the covering shell 14.

It should be noted here that due to the fact that the removable container 12 is not rotationally symmetrical - the cross section of the lower portion 302 has an ellipse shape - and the housing 20 is of complementary geometry to the lower portion 302 of the removable container 12 - in this case also having an ellipse-shaped cross section - the removable container 12 is blocked from rotating around the axis X, relative to the covering shell 14. In other words, the removable container 12 and the covering shell 14 are integral in rotation around the axis for the effect of preventing rotation around the X axis of the removable container.

The invention is not limited only to the embodiments described above with reference to the figures, but is, on the contrary, capable of numerous variants accessible to those skilled in the art. In particular, the characteristics of the different embodiments described can be combined in embodiments not illustrated in the figures.

Furthermore, the side wall of the removable container may in particular be of substantially hemi-ellipsoidal shape or even of polyhedral shape.

The bottom 40 of this removable container may not be flat. Preferably, the bottom 40 of the removable container is shaped to cause an imbalance of the removable container when the bottom of the removable container is placed on a flat support. The bottom 40 is for example formed by a non-flat projecting relief. Alternatively or additionally, the bottom of the removable container is made by a face of a projecting relief, which can be flat, such that the line joining the center of the face and the center of gravity of the removable container forms an angle not flat with the direction of the weight of said removable container, when the bottom thereof is placed on a flat support.

According to another aspect, in the example illustrated by the figures 14 to 20 , the ring 202 is fixed on the covering shell 14 by force fitting. Alternatively, the ring 202 can be fixed on the covering shell 14 by gluing, welding or any other means known to those skilled in the art. Preferably, the ring 202 is fixed on the covering shell 14 in a durable manner, so that the ring 202 remains mounted on the covering shell 14 in the event of removal of the removable container 12. In particular, the dismantling of the ring 202 of the trim shell 14 may require the use of a tool.

In the examples described, the elastic interlocking reliefs are distinct, carried by distinct tabs. However, an example can be imagined with a single elastic nesting relief, respectively on the covering shell and on the removable container, this elastic nesting relief can then be discontinuous.

Finally, the lid can be fixed on the removable container by screwing, as in the examples described previously or, alternatively, by elastic fitting, by tightening, by magnetization, by means of a bayonet fixing or by any other means accessible to the man of the art.
