Description

Description Title of the invention: REFILL AND PACKAGING JAR FOR A COSMETIC PRODUCT COMPRISING SUCH A RECHARGE Technical field of the invention

[0001] = The invention relates to a refill for a packaging pot of a product cosmetic. The invention also relates to a jar for packaging a product cosmetic comprising such a refill. State of the art

[0002] — The packaging pots for a cosmetic product consist of an assembly typically comprising a receptacle and a refill containing the product cosmetic. The refill is generally designed so that it can be placed removable in the receptacle. Thus, when the refill is empty, it can be either discarded or refilled with cosmetic product. cosmetic product is therefore not directly contained in the receptacle but in the recharge.

[0003] — Receptacles used in cosmetic product packaging pots can be of very varied shapes and sizes, shapes and sizes which are not not always adapted to those of the refill that the receptacles must accommodate. In this regard, the state of the art has sought to find ways of adaptation and / or to hold the refill in the receptacle.

[0004] — Document FR 3 108 588 discloses a product packaging pot cosmetic comprising a receptacle 8 and a refill 1 suitable for insertion into the re- receptacle. In order to reduce the clearance between the receptacle and the refill, the pot is provided with an elastomeric element 15 intimately connected to an inner wall of the re- receptacle so as to project from said interior wall. The elastic element- tomeric 15 is in the form of an annular band overmolded on the part upper part of the receptacle. The annular strip is possibly provided with studs 16 intended to ensure the positioning of the refill 1 in the receptacle.

[0005] If in such a pot, the clearance between the receptacle and the refill is reduced, or even in- existing, it is however not practical. Indeed, the elastomeric element 15 must be rigorously fixed to the inner wall of the receptacle to prevent it from coming off after several reloads. If it comes off the inner wall, the pot is not no longer usable and must be discarded. Furthermore, as the elastomeric element is overmolded on the receptacle, the latter must be made of a compatible material with overmolding, which limits the choice of materials. When the receptacle is made In plastic, the elastomeric element and the receptacle can be formed by bi-material injection. However, this process is complex because it requires precise adjustment of the alignment between the machines injecting the materials in order to obtain a good quality overlay. Document FR 3 108 584 discloses a cosmetic product packaging pot comprising a receptacle 13 and a refill | capable of being inserted into the receptacle. Unlike document FR 3 108 588, the elastomeric element 8 is overmolded onto the refill 1, in particular onto a cylindrical cup 2 of the refill, instead of being overmolded onto the receptacle 13. The elastomeric element 8 is in the form of a plurality of strips, in this case three strips, arranged regularly around the entire circumference of the cup 2. Each strip projects relative to an outer surface of the cup and comprises one end adjoining an upper edge of the cup 2. These ends may be covered by a stud 9, also projecting relative to the outer surface, which ensures that the refill is held in the receptacle. Like document FR 3 108 588, the use of an elastomeric element directly overmolded onto the refill limits the choice of materials that can be used for the refill and / or complicates the refill manufacturing process. In addition, in this case other problems arise. Indeed, the refill cannot be integrated into a single-material recycling process when it is bi-material. However, unlike the receptacle, it is intended to be used as a consumable, which, in the long term, can generate a large quantity of waste that is difficult to exploit. In addition, the presence of the strips of the elastomeric element around the entire circumference of the cup makes the cup unattractive. However, the appearance of the refill is important because the user associates it with the value of the cosmetic product it contains. An unattractive refill depreciates the value of the product it contains. The invention overcomes at least some of the above-mentioned problems. Summary of the invention In this regard, the invention proposes a refill for a jar for packaging a cosmetic product extending along a central axis X, capable of receiving the cosmetic product, and comprising a rigid body defined by a peripheral wall having an open upper end surrounded by a collar extending outwards, and a lower end closed by a bottom wall. This refill is mainly characterized in that it includes wedging means in the pot, deformable and defining, with an external surface of the peripheral wall, at least one cavity with variable volume depending on the wedging. The main idea of ​​this invention is to use the volume of the cavity to Place the refill in the container's receptacle. When the refill is not yet inserted into the container, the volume is at its maximum. In the working position, when the refill is inserted into the container, the volume is at its minimum. By inserting the refill into the receptacle, the wedging means are more or less compressed and therefore deformed upon contact with the receptacle, in particular depending on the clearance that exists between the refill and the receptacle. The greater the compression, the more the volume of the cavity decreases. This variation in the volume of the cavity makes it possible to absorb the existing clearance while maintaining contact between the refill and the receptacle via the deformation of the wedging means. The compression applied to the perimeter of the refill can be more or less important, because it depends not only on the clearance, but also on the dimensional variations of both the refill and the receptacle. According to different characteristics of the invention which may be taken together or separately: said wedging means consist of at least one external wedging wall and flexible, arranged opposite and at least partially at a distance from the external surface of the peripheral wall, said cavity being defined between the wedging wall and the peripheral wall. each wedging wall is curved in shape. each wedging wall is mounted on the peripheral wall by interlocking of corresponding shapes. the peripheral wall has a female shape made in its surface external, into which a male form provided for this purpose fits on the wedging wall. each wedge wall has an inwardly curved shape with a top arranged in contact with the peripheral wall of the bucket, said shape male protruding from the top of the wedging wall. each wedge wall has a curved shape towards the outside with a apex located at a distance from the peripheral wall of the bucket, said male shape projecting from a lower end of the wedging wall. each wedging wall has an upper end in contact with the body. the upper end of the wedging wall rests against the collar. the upper end of the wedging wall rests on the ex- surface interior of the peripheral wall, near the collar. the upper end of the wedging wall rests in the angle formed between the peripheral wall and the collar. the refill has a single wedging wall extending around the entire perimeter upper body. the shim wall consists of a removable ring. the refill has several wedging walls distributed regularly around of the body. each wedge wall extends over an angular sector of the body. the body and the wedging wall(s) are made of the same material. The invention further relates to a jar for packaging a cosmetic product comprising a receptacle and a refill, as described previously, inserted into the receptacle, the wedging means being wedged against the receptacle so as to absorb the play existing between the refill and the receptacle. Brief description of the figures Other objects, characteristics and advantages of the invention will appear more clearly in the description which follows, made with reference to the appended figures, in which: - [Fig. 1] is a sectional view of a packaging pot provided with a refill according to a first embodiment of the invention; - [Fig.2] is a perspective view of the upper part of the receptacle according to the first embodiment; - [Fig.3] is an enlarged sectional view of the upper left part of the receptacle of [Fig.2]; - [Fig.4] is an enlarged sectional view of the upper left part of a receptacle according to a 2nd embodiment of the invention; - [Fig.5] is an enlarged sectional view of the upper left part of a receptacle according to a 3rd embodiment of the invention; - [Fig.6] is an enlarged sectional view of the upper left part of a receptacle according to a 4th embodiment of the invention; - [Fig.7] is an enlarged sectional view of the upper left part of a receptacle according to a 5th embodiment of the invention; - [Fig.8] is an enlarged sectional view of the left part of a receptacle according to a variant of the 2nd embodiment of the invention. Detailed description of the invention In the remainder of the description, elements having an identical structure or similar functions will be designated by the same references. By convention, the "axial" direction corresponds to that of the main extension of the pot, illustrated by the X axis in [Fig.1], and the "radial" direction is orthogonal to the axial direction. In the detailed description of the figures which follow, we will use in a non-limited manner- mitative the terms "upper" and "lower" or "top" and "bottom" in reference to the axial direction. Similarly, the terms "outer or external" and "inner or internal" are used in reference to the radial direction, an outer element being radially further from the X-axis than an inner element. With reference to [Fig. 1], the invention relates to a cosmetic product packaging pot comprising a receptacle 4 and a refill 1 inserted into the receptacle 4. Refill 1 corresponds to a cup, and contains the cosmetic product. The refill is removable and can be manually removed from the packaging pot, especially when it is empty, so that the user can insert a new filled refill. Refill 1 and receptacle 4 can therefore be sold separately. According to one embodiment of the invention, the receptacle 4 is rigid. In addition to the fact that this gives it improved mechanical strength, this gives it a longer service life. By way of non-limiting example, the receptacle can be made of glass. It is thus possible to obtain a packaging pot having an attractive aesthetic appearance by taking advantage of both the transparency of the glass receptacle 4 and the aesthetic appearance of the refill 1. The receptacle 4 comprises a body 40 surmounted by a neck 44. The receptacle 4 is open at the top, and closed at the bottom by a base 41. In this example, the receptacle 4 has a constriction at the neck 44, that is to say that the internal diameter d1 of the neck 44 is less than the internal diameter d3 of the body 40. However, a receptacle 4 with a neck 44 having an internal diameter d1 identical to the diameter d3 of the body 40 also falls within the scope of the present invention. As illustrated in [Fig.1], the neck 44 has an internal diameter d, greater than the external diameter d, of the refill 1 in order to have a clearance allowing the insertion of the refill 1 into the receptacle 4. Similarly, if the neck 44 and the body 40 had the same internal diameter d1, d3, the latter would be less than the external diameter d2 of the refill 1 to allow its easy insertion. The neck 44 has a means 46 for fixing a lid (not shown) for closing the packaging pot once the refill 1 is positioned in the receptacle. The fixing means 46 may consist, for example, of an external thread cooperating with an internal thread provided in the lid. The refill | contains the cosmetic product, which can be fluid, in particular liquid or viscous, or which can be powdery for example. It is therefore sold to the end user in a hermetically sealed form, which protects the cosmetic product from the external environment. This airtight closure is traditionally achieved by means of a seal. Once the seal has been removed by the user and the refill | is inserted into the receptacle 4, it is the lid of the receptacle which closes the packaging pot and ensures that the cosmetic product is protected from the external environment. The refill | comprises a rigid body 2 defined by a peripheral wall 10 having an open upper end surrounded by a collar 16 extending towards the outside of the refill 1, and a lower end closed by a bottom wall 11. As illustrated in the figures, the peripheral wall 10 is of substantially cylindrical shape. That being said, the shape of the lateral peripheral wall 10 is not limited to the illustrated embodiment. It may be of any other desired shape, provided that it does not depart from the inventive concept underlying the present invention. The upper part of the refill | is more particularly illustrated in [Fig.2]. We can clearly see the peripheral wall 10 and the collar 16. There is therefore an angle 17 between the lateral peripheral wall 10 and the collar 16. This angle 17 is preferably between 45° and 135°C. In the example presented, the collar 16 is oriented substantially perpendicular to the X axis. For example, the angle 17 is 90°C. The collar 16 rests on the upper edge of the neck 44 of the receptacle 4 when the refill 1 is inserted therein. The peripheral wall 10 has an inner surface and an outer surface 14. The inner surface and the bottom 11 delimit an internal volume of the body 2 intended to accommodate the cosmetic product. The outer surface 14 is, as illustrated in [Fig. 1], intended to be opposite an inner surface of the receptacle 4. As also illustrated in all the figures, the refill 1 according to the invention comprises, in addition to the body 2, wedging means making it possible to ensure its wedging, and therefore its maintenance in the receptacle 4. These wedging means cooperate with the outer surface 14 of the peripheral wall 10. They are deformable, and define at least one cavity 5 with variable volume depending on the wedging. The wedging means consist of at least one wedging wall 3, external and flexible, arranged opposite and at least partially at a distance from the external surface 14 of the peripheral wall 10. The cavity 5 is defined between the wedging wall 3 and the peripheral wall 10. The air volume of the cavity 5 is variable, depending on the deformation undergone by the wedging wall 3. The closer the wedging wall 3 gets to the peripheral wall 10, the more the volume decreases. The air volume is maximum when the wedging wall 3 is not subject to any stress, in other words when the refill 1 is not inserted into the receptacle 4. Concretely, as mentioned previously, there is a functional game between the outer surface 14 of the refill | and the inner wall of the receptacle 4 (at the neck 44 and / or the body 40). This clearance corresponds to d1-d2, and / or d3 — d2. This clearance allows easy insertion of the refill 1 into the receptacle 4, but also has the disadvantage of having a refill 1 which moves in the receptacle 4 when the user takes cosmetic product. The wedging wall 3 being offset relative to the outer surface 14 of the refill 1, it comes into contact with the inner wall of the receptacle 4 when the refill 1 is inserted, at the neck 44 and / or at the body 40 depending on their diameters and its position on the body 2. Thus the wedging wall 3 presses against the receptacle 4, and deforms thanks to its flexibility and the presence of the cavity 5 located just behind, the volume of which varies accordingly. The wedging wall 3 is then deformed and wedges the refill 1 in the receptacle 4.At the end of insertion, the refill | is wedged, and no longer moves when the user comes to take the product. The wedge wall 3 compensates for the play that exists between the refill 1 and the receptacle 4. . Preferably, the wedging wall 3 is curved in shape, to clearly delimit the cavity, and to deform more easily. Generally, the refill 1 may comprise a single wedging wall 3 which goes completely around the body 2, or it may comprise several wedging walls 3 which are distributed around the body 2. In the case of a plurality of wedging walls 3, these are preferably distributed regularly around the body 2. They extend over a predefined angular sector. The wedging walls 3 thus form bosses on the refill 1. In the case of a single wedging wall 3, this is similar to a ring surrounding the body 2. The wedging wall 3 has a wedging function with the interior of the receptacle 4, and does not have a sealing function. If sealing is necessary, it will be achieved with the upper surface of the receptacle 4 and the cover. There are several embodiments of this wedging wall, which will be described below. In the 1st embodiment shown in Figures 1 to 3, there is a single wedging wall 3 corresponding to a ring. In this case, the wedging wall 3 is a part independent of the body 2, the whole forming the refill 1. This ring 3 is arranged in the upper part of the body 2, around a section of its peripheral wall 10. It is arranged just under the collar 16. When the refill 1 is inserted into the receptacle 4, the ring 3 is located at the height of the neck 44. [Fig.3] provides a better view of this wedging wall 3 which is curved outwards. The wedging wall 3 is mounted on the peripheral wall 10 by interlocking corresponding shapes. The peripheral wall 10 has a female shape made in its outer surface 14, into which a male shape provided for this purpose on the wedging wall 3 fits. In the case presented, the female shape consists of a groove 15 formed on the outer surface 14, in the thickness of the peripheral wall 10. And the male shape projects from a lower end 30 of the wedging wall 3, and fits into the groove 15. In the present case, the groove 15 is annular. Alternatively, the male form could correspond to the lower end 30 itself. According to the invention, the wedging wall 3 is held both against the groove 15 and against the angle 17 formed between the peripheral wall 10 and the collar 16. The wedging wall 3 is therefore in stable support against both the groove 15 and the angle 17, which prevents it from moving axially relative to the body 2 but nevertheless allows it to retain its capacity to deform. The positioning of the wedging wall 3 relative to the body 2 is guaranteed even during the insertion of the refill 1 into the receptacle 4. Indeed, thanks to its stable supports, the wedging wall 3 does not move even if the insertion is a little hard. That being said, the wedging wall 3 is removable, and therefore can be removed from the body 2 provided that the user takes a voluntary action in this direction by removing the wedging wall from the groove 15. However, this goes beyond the normal scope of use of the refill 1 and is not desired. Furthermore, the wedging wall 3 makes it possible to hold the refill 1 in the receptacle 4. This results on the one hand from its deformable nature which makes it possible to compensate for the play which may exist between the refill | and the receptacle 4 and on the other hand from the stability which is conferred on it by its stable supports both against the annular groove 15 and the angle 17. Furthermore, the wedging wall 3 acts as a brake when the refill 1 reaches its final position in the receptacle 4 because the wedging wall 3 is close to the upper end of the body 2 which is the last part to enter the receptacle 4, which makes it possible to slow down the axial movement of the refill 1 at the end of its travel. The final position of the refill 1 in the receptacle 4 is reached when the collar 16 rests on the neck 44 of the receptacle 4. The wedging wall 3 has a generally curved shape having a concavity oriented towards the body 2. The wedging wall 3 comprises the lower end 30 resting on the annular groove 15, an upper end 31 resting on the angle 17, and a curved portion 32 connecting said lower 30 and upper 31 ends, the curved portion 32 comprising the concavity oriented towards the body 2. In other words, the wedging wall 3 forms a boss on the refill 1. The top S of the boss is located at a distance from the peripheral wall 10. The curved portion 32 creates an air cavity 5 between the deformable ring 3 and the body 2. Thus, the air cavity S is delimited on the one hand by the inner surface of the wedging wall 3 and on the other hand by the outer surface 14 of the body 2 located opposite the concavity, this over the entire circumference of the peripheral wall 10. The volume of this cavity 5 varies according to the stresses exerted on the wedging wall 3. The wedging wall 3 has sufficient flexibility so that the curved portion 32 can deform elastically accordingly. The stresses are exerted on the outer surface of the wedging wall 3 at the level of the curved portion 32. The closer the vertex S of the curved zone 32 gets to the body 2, the smaller the volume of the cavity 5 will be. The volume of the cavity 5 is at a minimum when the refill | reaches its final position and an inner surface of the receptacle 4 is pressed against the wedging wall 3, and compresses it. The groove 15 is defined by a bottom delimited by two side walls, lower 33 and upper, oriented perpendicular to the peripheral wall 10 of the body 2. Preferably, a mechanical attachment is made between the lower end 30 of the wedging wall 3 and the groove 15. It is called "mechanical" because it results from a fitting of the male shape projecting from the lower end 30, in the groove 15. The male shape creates a first shoulder at the level of the lower end 30 of the wedging wall 3. And the lower side wall 33 of the groove 15 creates a second shoulder with the external surface 14 of the body 2. In this case, the attachment consists of a fitting of the first shoulder into the second shoulder. Other types of attachment can be envisaged without prejudice to the inventive concept at the basis of the present invention. Advantageously, the upper end 31 has a rounded shape which follows the contours of the angle 17. This makes the support more reliable. The positioning of the wedging wall 3 relative to the body 2 is thus guaranteed. In this 1 embodiment, it would be entirely conceivable for there to be a plurality of wedging walls 3 distributed around the refill 1, rather than a single wedging wall 3 going around the refill 1. In the 2nd embodiment presented in [Fig.4], the wedging wall 3 has the same characteristics as those of the 1st embodiment, with the exception of the support of its upper end 31 which is made against the external surface 14 of the peripheral wall 10 of the body 2, and no longer in the angle 17. In this embodiment, the wedging wall 3 can be arranged at any height of the body 2, as well as in the upper part, in the lower part as illustrated in [Fig.8], or in the central part. Of course, this will depend on the shape and dimensions of the receptacle 4, so that the wedging wall 3 rests against an interior surface of the receptacle 4 (neck 44 or body 40). In the 3rd embodiment presented in [Fig.5], the wedging wall 3 has the same characteristics as those of the 1st embodiment, with the exception of the support of its upper end 31 which is made against the collar 16, and no longer in the angle 17. The shape of the wedging wall 3 is adapted accordingly, so that the upper end 31 has a sufficiently large support zone against the collar 16. In the 4th embodiment presented in [Fig.6], the wedging wall 3 is this time curved inwards. Its top is in contact with the peripheral wall 10, and its lower and upper ends 30, 31 are free and at a distance from the peripheral wall 10. The cavity 5 is this time divided into two zones, an upper zone located above the top, and a lower zone located below the top, the two zones always being between the wedging wall 3 and the peripheral wall 10. The male form projects from the top of the wedging wall 3, and fits into a female form, of the groove type 15, provided for this purpose in the peripheral wall 10 of the body 2, similar to what has been described previously. In this case, there are no longer two supports against the body 2, but a single support at the top of the wedging wall Z The free ends 30, 31 will come into contact with the inner wall of the receptacle 4 to ensure wedging. In the 5th embodiment presented in [Fig.7], the wedging wall 3 has the same characteristics as those of the 1st embodiment, except that this time it is the upper end 31 which is fitted into the groove 15, and no longer the lower end 30. The groove 15 is located higher in the peripheral wall 10, at the level of the angle 17. The lower end 30 bears against the outer surface 14 of the peripheral wall 10. Preferably, the body 2 and the wedging wall 3 are made of the same material, the refill 1 can be recycled in a processing line dedicated to the material used. In other words, the refill 1 according to this embodiment can be recycled in a single-material recycling channel, as there are more and more of them. Advantageously, the body 2 and the wedging wall 3 are made of polymer. For example, polypropylene, polyethylene or recycled polypropylene. Or with bioplastic techniques, chemical PCR (polymerase chain reaction), mechanical PCR. Or PET (polyethylene terephthalate), POM (polyoxymethylene), PA PBT, TPE (thermoplastic elastomer), etc. The manufacture of objects by a single-injection process of these materials is known and mastered, so that they can be manufactured with different levels of hardness, deformability, resistance to breakage, etc. This makes it possible to manufacture a refill | in which the body 2 and the wedging wall 3 are made of the same material. Furthermore, in addition to the fact that these materials can easily be adapted, they are inexpensive and suitable for the packaging of cosmetic products. Although body 2 and the wedging wall 3 are made of the same material, we understand that body 2 is rigid compared to the wedging wall 3 which is deformable and flexible. Indeed, the wedging wall 3 is thinner and can deform given the cavity 5 located behind it. It's all a question of thickness, and shape. When the body 2 and the wedging wall 3 are made of different materials, the materials mentioned above can be used independently for one or the other. The materials mentioned can be used with different levels of hardness and therefore deformability. Of course, in this description the terms "rigid" and "deformable" are used for simplification and according to the commonly accepted meaning. Optionally, as illustrated in [Fig.2], the refill 1 further comprises a tab 6 which can serve as a means of gripping the ring 3, or as a means of error correction when positioning the ring 3. In the following, the principle of assembly of the packaging pot according to the invention is described. Prior to assembly of the pot, the refill 1 is delivered with the wedging wall(s)3 arranged around the body 2 in accordance with the invention. The user places the refill 1 in alignment with the upper opening of the receptacle 4, then gradually brings the refill 1 closer to the opening until the refill 1 is inserted into the receptacle 4. This insertion is carried out along a mounting axis X aligned with the axis of symmetry of the refill 1 and the axis of symmetry of the receptacle 4. The refill 1 reaches the final position when the collar 16 is resting on the neck 44. When the refill 1 approaches the final position, the user may feel a slight resistance resulting from the contact of the wedging wall(s) against the inner surface of the receptacle 4.Thus, the user will have to exert slightly more pressure than previously exerted so that the wedging wall(s) 3 deform to compensate for the play and the refill 1 reaches the final position. The refill 1 can therefore be inserted into the receptacle 4 in a single movement, with a rectilinear translational movement. To remove refill 1, the user grips it by inserting a finger inside the empty refill and pressing the finger against the inner wall so as to lift it. Upon removal, the wedging wall(s) 3 remain in position on the body 2, and are thus also removed with the refill 1. The configurations shown in the figures cited are only possible examples, in no way limiting, of the invention which on the contrary encompasses the variants of shapes and designs within the reach of those skilled in the art.
