Description

[Technical Field]

[0001] The present disclosure relates to a removable container for a refillable cosmetic packaging device, and to a refillable cosmetic packaging device including such a removable container. Cosmetic refills including such a removable container are also described. [Background technology]

[0002] Users are particularly sensitive to the aesthetics of cosmetic packaging devices, however the cost of aesthetic packaging devices is high, thereby increasing the cost of cosmetics sold commercially in this format.

[0003] An idea has developed which consists in providing an aesthetic packaging device which includes a separate removable container which is less aesthetic but less expensive to package. Preferably, the container is removable so that the packaging device can be refilled by replacing the removable container.

[0004] The removable container is generally made of plastic. However, such plastic containers lead to environmental issues, especially recycling issues, to which users are becoming increasingly sensitive. Furthermore, recycling standards for packaging devices are becoming ever stricter, which tends to limit or even eliminate the use of plastic.

[0005] Patent document 1 also describes a container for fluids or powdery substances, including an outer element made of glass and an inner element inserted into the mouth of the outer element. At the mouth of the outer element, the inner element includes at least two peripheral ridges that secure the inner element to the outer element at least when elastically deformed. The inner element can be made of a paper- or paperboard-based material. The inner element can include a lining or coating of a paper- or paperboard-based material. The lining or coating can be made of a plastic material, such as PE, PLA, HDPE, or PP, or can be waxed. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] European Patent Application Publication No. 4 233 636 Summary of the Invention [Problem to be solved by the invention]

[0007] The present disclosure improves the situation. In particular, the aim of the present disclosure is to propose a packaging device for cosmetic products that is refillable and does not present at least some of the drawbacks mentioned above. [Means for solving the problem]

[0008] To this end, a removable container for a cosmetic product is proposed, which is intended to be received in the outer shell of a packaging device for the cosmetic product, and the removable container includes a cup made of a cellulose-based material, and the cup is covered on an inner surface intended to be oriented toward the cosmetic product with a barrier film adapted to limit or even prevent the migration of at least one component of the cosmetic product through the cup. The barrier film can be a multilayer film. The barrier film can include at least five layers. One of the at least five layers can be made of a cycloolefin copolymer.

[0009] Preferably, the removable container may include one or more of the following features, either alone or in combination:

[0010] The cellulose-based material contains fibers from at least one of bamboo, bagasse, wood, and recycled paper.

[0012] The barrier film includes at least one layer of at least one of polyethylene, polypropylene, polyamide, ethylene vinyl alcohol, ethylene vinyl acetate.

[0013] The barrier film contains just seven layers.

[0014] The barrier film comprises seven subsequent layers, from the first layer designed to be oriented towards the cosmetic product, to the seventh layer oriented towards the cellulose-based material from which the cup is made. a first layer of polyethylene, a second layer of a cycloolefin copolymer; a third layer of a chemical binder, in particular a layer of a polymer containing an ethylene or olefin-based adhesive resin; a fourth layer of ethylene vinyl alcohol, a fifth layer of a chemical binder, in particular a layer of a polymer containing an ethylene or olefin-based adhesive resin; a sixth layer of a cycloolefin copolymer, and Seventh layer of ethylene vinyl acetate.

[0015] The removable container further comprises an inner seal that closes the cup, the inner seal preferably being made of aluminium or an aluminium alloy, a plastic material, in particular polyethylene terephthalate or polyethylene furanoate, or paper, in particular coated paper.

[0016] The inner seal is covered on at least one inner surface intended to be oriented inside the cup towards the cosmetic product with a coating that is impermeable to liquids and preferably gases, the impermeable coating preferably containing an epoxy resin and a methacrylate olefin polymer.

[0017] The cup presents a base, an opening and a lateral wall between the base and the opening.

[0018] The lateral wall of the cup preferably forms a substantially flat flange extending between an inner edge bounding the opening of the removable container and an outer edge opposite the inner edge, the flange preferably being at least partially covered by a barrier film.

[0019] The flange exhibits at least one of a portion of decreasing thickness toward the outer edge of the flange and a thinned portion near the outer edge.

[0020] The flange presents a thinned portion extending to the outer edge.

[0021] The flange exhibits a thinning away from the outer edge.

[0022] The inner seal is fixed, in particular bonded or welded, onto the flange near a fixing area, which is located closer to the inner edge of the flange than the area of ​​reduced thickness or thinned section, respectively.

[0023] The removable container includes a plurality of ridges on its outer surface, the ridges preferably being equiangularly distributed on the removable container.

[0024] At least one ridge is formed on the cup, in particular on the lateral wall of the cup.

[0025] At least one ridge is formed on a shell of cellulose-based material, particularly the same material as the cup, which shell receives the cup.

[0026] The shell forms a flange, and the cup and shell are fixed together at their respective flanges, particularly by bonding or welding.

[0027] The shell is covered on the face oriented towards the cup by a barrier film, the barrier film on the shell being preferably the same as the barrier film on the cup.

[0028] The cup contains the cosmetic product.

[0029] The lateral wall presents a shoulder near the opening of the cup.

[0030] According to another aspect, a cosmetic refill is described that includes at least one removable container as described above in a sealed, preferably airtight package, or in a cellulose or molded paperboard case, or in any combination thereof.

[0031] According to yet another aspect, a packaging device for cosmetics is described, including an outer shell and a removable container as described above in any combination thereof, wherein the outer shell defines a compartment for receiving the removable container, the compartment for receiving the removable container opening at an outlet in the outer shell. The outer shell is preferably one of glass, metal, ceramic, porcelain, quartz, and plastic, particularly polymethylmethacrylate, polystyrene, polycarbonate, polyethylene terephthalate, ionomer resins such as ethylene vinyl copolymers known by the trade name Surlyn®, polyethylene, polypropylene, copolyester, natural stone, synthetic stone, wood, and urea formaldehyde.

[0032] The removable container can be held in place on the outer shell by deformation of at least one ridge on the removable container, preferably at least two ridges on the removable container if appropriate, in contact with the outer shell, and the removable container more preferably contains a cosmetic product.

[0033] The deformation of the at least one ridge of the removable container may be elastic.

[0034] The deformation of the at least one ridge of the removable container may be plastic deformation.

[0035] The cosmetic packaging device may further include a lid that is capable of closing the outlet of the recess in the outer shell, particularly by being fixed onto the outer shell, even when the removable container is received in the recess in the outer shell.

[0036] The lid can be one of glass, metal, ceramic, porcelain, quartz, plastic, natural stone, synthetic stone, wood, and urea formaldehyde.

[0037] Other features, details and advantages will become apparent upon reading the following detailed description and examining the accompanying drawings. [Brief explanation of the drawings]

[Figure 12]10 shows a detail of a longitudinal section of a sixth example of a removable container fixed on an outer shell in a packaging device according to FIG. 1; DETAILED DESCRIPTION OF THE INVENTION

[0039] In the remainder of the description, identical elements or elements having identical functions will bear the same reference numerals. For the sake of brevity in this description, these elements will not be described in detail in each example. Instead, only the differences between different examples will be described in detail.

[0040] 1 shows an example of a refillable cosmetic packaging device 10 (hereinafter referred to as packaging device 10). The packaging device 10 essentially includes a removable cosmetic container 12, an outer shell 14 that receives the removable container 12, a lid 16, and a seal 18 retained by the lid 16.

[0041] The lid 16 is particularly one of glass, metal, ceramic, porcelain, quartz, plastic, natural stone, synthetic stone, ceramic, porcelain, wood, and urea-formaldehyde. The lid 16 can be several parts assembled together, particularly an outer body receiving an insert, the insert forming a means of fastening onto the outer shell, particularly a helical thread.

[0042] The seal 18 is intended to prevent the cosmetic product P contained in the removable container 12 from drying out and / or its volatile components from evaporating. The seal 18 is tightly held, for example, between the bottom 17 of the lid 16 and the edge 19 of the outer shell 14, and the seal closes the outlet 21 of the removable container 12.

[0043] More specifically, the outer shell 14 defines a recess 20 intended to at least partially receive the removable container 12. The recess 20 is surrounded by a rim 19 and opens at an outlet 22 in the outer shell 14.

[0044] The outer shell 14 also forms a collar 24, the free end of which forms a lip 19. The lip 19 extends around the outlet 22. The collar 24 now presents a helical thread 25 that is complementary to a thread 27 on the inside of the lid 16. The lid 16 can thus be secured to the outer shell 14 by a threaded engagement. Of course, other means of securing the lid 16 onto the outer shell 14 are possible and accessible to those skilled in the art. For example, the lid 16 can be snapped (or "clipped") onto the outer shell 14.

[0045] Here, the outer shell 14 is shaped to allow it to balance on a flat support. As shown, the outer shell 14 rests on such a flat support by means of a contact area 26 that surrounds a bottom 28 that is recessed relative to the contact area 26. In one variant, the bottom 28 is not recessed relative to the contact area 26 but rather forms part of the contact area 26. The contact area 26 has, for example, a closed contour, in particular a circular or oval contour, or a contour of any other shape. Alternatively, the contact area 26 is formed by a separate leg 29 of the outer shell 14 that extends from the bottom 28 of the outer shell 14, as shown. The bottom 28 of the outer shell 14 can present a through-hole 30 that opens firstly on the bottom 28 and to the outside of the outer shell 14, and secondly in the recess 20, as shown. The hole 30 can advantageously allow a finger to be inserted. To do this, the hole 30 can present a diameter of 15 mm or less, preferably 10 mm or less. Alternatively, however, the holes 30 have a diameter that does not allow for the insertion of a finger, for example less than 5 mm, preferably less than 2 mm. In this particular case, the function of the holes 30 is to allow air contained in the recesses 20 to escape into the outer shell 14 during assembly of the removable container 12. Alternatively, the bottom 28 lacks holes 30.

[0046] According to one embodiment not shown, the flat bottom 28 of the outer shell 14 is at least partially covered by a label, which may or may not cover the hole 30. The label may carry any information regarding, for example, the product brand and / or its composition and / or its method of use and / or its possible expiration date.

[0047] Between the bottom 28 and the edge 24 around the outlet 22, the outer shell 14 now forms a lateral wall 32 that is at least partially tubular. The part of the lateral wall 32 near the flange 19 forms the collar 24. The lateral wall 32 is rotationally symmetric, preferably completely rotationally symmetric, about a main axis A14 of extension of the outer shell 14 (hereinafter referred to as the axis A14 of the outer shell 14). Of course, this shape of the outer shell 14 is not limiting, and it can assume virtually any shape, in particular any shape that aims to ensure the aesthetics of the packaging device 10. For example, between the bottom 28 and the flange 19, the outer shell 14 can form a lower part near the bottom 28 that is parallelepipedal, and an upper part near the flange 19 that is tubular, in particular having a shape that is approximately rotationally symmetric, preferably completely rotationally symmetric, about the axis A14 of the outer shell 14.

[0048] The outer shell 14 is preferably opaque, which imparts an aesthetic effect to the outer shell 14 and the packaging device 10 that is appreciated by users. The outer shell 14 may alternatively be at least partially translucent and / or may exhibit portions that are at least partially translucent.

[0049] The outer shell 14 can be made of glass, metal, ceramic, porcelain, quartz, and plastic, particularly polymethylmethacrylate, polystyrene, polycarbonate, polyethylene terephthalate, ionomer resins such as ethylene vinyl copolymers known by the trade name Surlyn®, polyethylene (PE), polypropylene (PP), copolyesters, natural stone, synthetic stone, wood, and urea-formaldehyde. Preferably, the outer shell 14 is made of glass, more preferably colored glass, and especially lacquered glass. It is noteworthy that the removable container 12 is made of a material that is sufficiently flexible to accommodate the outer shell 14, which exhibits relatively high manufacturing tolerances. Therefore, many different materials can be implemented to make the outer shell 14.

[0050] Additionally, the removable container 12 now includes a cup 34 and a shell 36 secured together, the shell 36 forming a recess that at least partially receives the cup 34 .

[0051] The cup 34 is made of a cellulose-based material. The cup 34 is covered on its inner surface 34A, which is intended to be oriented toward the cosmetic product, by a barrier film 38. Preferably, the barrier film 38 covers the entire inner surface 34A of the cup 34, particularly the inner surface 34A of the cup 34 that would otherwise come into contact with the cosmetic product P. Thus, the cosmetic product contained in the removable container 12 preferably comes into contact with the barrier film 38, rather than the cellulose-based material from which the cup 34 is made.

[0052] The function of the barrier film 38 is to limit or even prevent the migration of at least one ingredient of the cosmetic product through the wall of the cup 34 to the outside of the removable container 12. The barrier film 38 is therefore preferably impermeable to at least one of water, oil, volatile molecules such as silicones, short-chain alkanes, and gases. "Short-chain alkanes" herein refer to alkanes containing between 9 and 15 carbon atoms.

[0053] Cosmetics P are, for example, creams, emulsions, lotions, gels or oils for the skin, in particular for the body, hands, face, eye contour and / or feet, foundations, in particular liquid foundations, beauty masks, soaps, deodorant soaps, perfumes, eau de toilette, eau de cologne, bath and / or shower products, hair care products such as hair dyes, bleaches, hair straightening treatments, hair relaxers, cleaning styling setting treatments, in particular hair care treatments in the form of lotions, creams, oils, styling treatments in particular in the form of lotions, hair sprays, brilliantines, cleaning products, in particular in the form of lotions or shampoos, shaving products, in particular shaving foams or lotions, make-up products, in particular eye make-up products such as mascara, products for removing make-up from the face and / or eyes, products intended to be applied to the lips, such as lipsticks, lip glosses or lip balms, products for the care and painting of the nails, sun care products, sunless tanning products, skin whitening products, anti-wrinkle products. The cosmetic product P can in particular be in the form of a liquid, cream, gel, paste, powder or solid. The cosmetic product P can also be biphasic. For example, the cosmetic product P contains a suspending agent, in particular a suspending agent that is solid in a liquid phase, in the form of a cream or gel.

[0054] The cellulose-based material from which the cup 34 is made can contain fibers from at least one of bamboo, bagasse, wood, and recycled paper. The cellulose-based material can particularly include a mixture of these fibers. In particular, the cellulose-based material can include a mixture of 50% to 70% bamboo fiber by weight of fiber, particularly 60% bamboo fiber by weight of fiber, and a complementary amount of bagasse fiber up to 100% by weight of fiber.

[0055] The material from which the cup 34 is made can also contain dyes, particularly in the form of pigments of one or more different colors, and / or at least one moisture-proofing agent. The moisture-proofing agent is, for example, alkyl ketene dimer (AKD). The weight proportion of the dyes and moisture-proofing agent can be less than 10% of the weight of the material from which the cup is made. For example, the weight proportion of the moisture-proofing agent can be between 1% and 5%, preferably between 2% and 2.5%. The weight proportion of the dyes, particularly pigments, can then be less than 7.5%, particularly less than 5%.

[0056] The barrier film 38 is at least one of polyethylene (PE), polypropylene (PP), polyamide (PA), ethylene vinyl alcohol (EVOH), ethylene vinyl acetate (EVA), and cycloolefin copolymer (COC). The barrier film 38 can be multi-layered. The barrier film 38 can include at least five layers. The barrier film 38 can include exactly seven layers 38a-38g, particularly seven subsequent layers 38a-38g, starting from layer 38a oriented toward the cosmetic product contained in the removable container 12 and ending with layer 38g oriented toward the cellulose-based material from which the cup 34 is made, as shown in FIG. 3 . a first outer layer 38a of polyethylene (PE); a second layer 38b of cycloolefin copolymer (COC); a third layer 38c of a chemical binder, in particular a layer of a polymer containing an ethylene or olefin-based adhesive resin; a fourth layer 38d of ethylene vinyl alcohol (EVOH); a fifth layer 38e of a chemical binder, in particular a layer of a polymer containing an ethylene or olefin-based adhesive resin; a sixth layer 38f of cycloolefin copolymer (COC); and Seventh inner layer 38g of ethylene vinyl acetate (EVA).

[0057] The more layers the barrier film 38 contains, the more effective it is a priori. However, a large number of layers implies a significant thickness of the barrier film 38, which can then be difficult to apply to the cup 34, especially by lamination. Air bubbles can be trapped between the barrier film 38 and the cup 34, which can damage the appearance of the removable container 12 and / or the effectiveness of the barrier film 38.

[0058] The cup 34 has a generally bowl-shaped configuration and is rotationally symmetric about its axis of symmetry A34 (hereinafter referred to as the axis of the cup 34), which is intended to correspond to the axis A14 of the outer shell 14 when the removable container 12 is fixed thereon. The cup 34 thus presents a substantially flat bottom 33, preferably perpendicular to the axis A34 of the cup 34, and a lateral wall 35. The lateral wall 35 forms a flange 40. The flange 40 extends between an inner edge 40i surrounding an outlet 41 of the cup 34 and a free outer edge 40e opposite the inner edge 40i. The outlet 41 of the cup 34 corresponds to the outlet 21 of the removable container 12. In addition, the cup 34 presents a shoulder 42 near the flange 40. It is noted that the cup 34 presents a regular inner surface, lacking any concave relief, with the exception of the shoulder 42. It would be preferable to limit or even prevent the presence of such recessed reliefs, which are likely to be filled with difficult-to-remove cosmetic product P. Such recessed reliefs may therefore lead to waste of the cosmetic product P contained in the removable container 12, which may annoy users of the cosmetic packaging device 10.

[0059] For example, the cup 34 is molded. The thickness of the layer of cellulose-based material forming the cup 34 can be substantially constant over the majority of the cup 34. The thickness of the layer of cellulose-based material can in particular be greater than or equal to 0.4 mm, preferably 0.5 mm, and / or less than or equal to 1 mm, preferably 0.8 mm. The thickness of the layer of cellulose-based material can, for example, be equal to 0.65 mm. Alternatively, the thickness of the layer of cellulose-based material can vary. For example, the flange 40 can have a maximum thickness greater than the thickness of the remainder of the lateral wall 35 of the cup 34.

[0060] In addition, the shell 36 has a generally bowl shape and is rotationally symmetric about its axis of symmetry A36 (hereinafter referred to as the axis of the shell 36), which corresponds to the axis A34 of the cup 34 when the cup 34 and the shell 36 are fixed together. The shell 36 therefore presents a bottom 37 which is here substantially flat and preferably perpendicular to the axis A36 of the shell 36, and a lateral wall 39. The lateral wall 39 of the shell 36 forms a flange 44. The flange 44 extends between an inner edge 44i which surrounds the outlet of the shell 36 and an outer edge 44e which is here free and which is opposite the inner edge 44i.

[0061] The shell 36 thus forms a recess for receiving the cup 34. The flange 44 of the shell 36 is then secured to the flange 40 of the cup 34, securing the cup 34 and the shell 36 together. For example, the flange 44 of the shell 36 is joined to the flange 40 of the cup 34, particularly on the surface of the flange 40 of the cup 34 that is not covered by the film 38. Preferably, the cup 34 and the shell 36 are secured together only through their respective flanges 40, 44. In particular, a space is maintained between the lateral walls 35, 39 of the cup 34 and the shell 36. The bottoms 33, 37 of the cup 34 and the shell 36 may be spaced apart. Alternatively, the bottoms 33, 37 of the cup 34 and the shell 36 are preferably in contact without being secured together.

[0062] The shell 36, and in particular the lateral wall 39 of the shell 36, here presents reliefs 46 projecting from its outer surface 36E and oriented away from the cup 34. The at least one relief 46 is preferably formed by a change in the shape of the lateral wall 39 rather than by a local change in the thickness of the lateral wall 39. The at least one relief 46 preferably presents a width equal to only a portion of the circumference of the lateral wall 35 around the axis A12 of the removable container 12. In other words, the at least one relief 46 preferably does not take the form of a ridge or bead extending over the entire circumference of the lateral wall 35.

[0063] The shell 36 preferably exhibits a plurality of reliefs 46, in particular at least two such reliefs 46, preferably at least three reliefs 46, more preferably at least four reliefs 46, more preferably at least five reliefs 46, and even more preferably at least six reliefs 46, as shown in the figures, where the reliefs 46 are distributed around the axis A36 of the shell 36 at regular angles. The reliefs 46 here take the form of ridges in the wall of the shell 36. The reliefs 46 here are formed near the flange 44 of the shell 36. The reliefs 46 are preferably open towards the shell 36 to facilitate extraction of the shell 36.

[0064] Each relief 46 may be, for example: a height H46, measured along the direction of the axis A36 of the shell 36, between 5 mm and 10 mm, in particular equal to 7.5 mm; and / or a width L46 at mid-height between 5 mm and 10 mm, in particular equal to 9 mm, and / or depth P46 between 0.75 mm and 2 mm, in particular equal to 1.2 mm; Present the following.

[0065] Shell 36 is preferably a flexible material, particularly more flexible than the material from which outer shell 14 is made. Shell 36 is, for example, a cellulose-based material similar to cup 34, as described above, preferably the same cellulose-based material from which cup 34 is made. According to one example, shell 36 is not covered on any of its sides by a barrier film similar to barrier film 38 that covers inner surface 34A of cup 34, as described above. Indeed, such a film may not be useful, and shell 36 is not intended to come into contact with the cosmetic product contained in removable container 12.

[0066] For example, the shell 36 is molded. The thickness of the layer of cellulose-based material from which the shell 36 is made can be substantially constant over the majority of the shell 36. The thickness of the layer of cellulose-based material from which the shell 36 is made can be, in particular, 0.4 mm or more, preferably 0.5 mm, and / or 1 mm or less, preferably 0.8 mm. The thickness of the layer of cellulose-based material can be, for example, equal to 0.65 mm. Alternatively, the thickness of the layer of cellulose-based material from which the shell 36 is made can vary. For example, the flange 44 can have a maximum thickness greater than the thickness of the remainder of the lateral wall 39 of the shell 36. Alternatively or additionally, the thickness of the lateral wall 39 of the shell 36 can be less at the relief 46. The thickness of the lateral wall 39 of the shell 36 can be, in particular, equal to 0.6 mm at the relief 46.

[0067] The removable container 12 is shaped to be received in the recess 20 inside the outer shell 14, such that a flange 44 of the shell 36 rests on the edge 19 around the outlet of the outer shell 14. The removable container 12 is here held in place in the recess 20 inside the outer shell 14 by deformation of at least one relief 46 of the shell 36. Preferably, at least two reliefs 46, or even all reliefs 46, are deformed into contact with the outer shell 14 when the removable container is secured in the recess 20 inside the outer shell 14. To do this, for example: the flanges 40, 44 rest on the free end of the collar 24 surrounding the outlet 22 of the recess 20 in the outer shell 14, for example by choosing the diameter of the flanges 40, 44 of the cup 34 and of the shell 36 to be greater than the diameter of the outlet 22 of the recess 20 in the outer shell 14, in particular substantially equal to the diameter of the collar 24; For example, by selecting a diameter, excluding the relief 46, of the lateral wall 39 of the shell 36 that is less than the diameter of the outlet 22 of the recess 20 in the outer shell 14, a space is maintained between the collar 24 and the outer shell 14 and the lateral wall 39 of the shell 36, excluding the relief 46; For example, by selecting a diameter of the lateral wall 39 of the shell 36 at the relief 46 that is greater than the diameter of the outlet 22 of the recess 20 in the outer shell 14, at least locally, the relief contacts the collar 24 of the outer shell 14. Preferably, the diameter of the lateral wall 35 of the cup 34 is selected to be less than the diameter of the outlet 22 of the recess 20 in the outer shell 14 to prevent deformation of the cup 34 received in the outer shell 14.

[0068] The deformation of each relief 46 can be elastic and / or plastic. Preferably, the deformation of each relief 46 is elastic, allowing the removable container 12 in the outer shell 14 to be removed and replaced. Preferably, as shown in Figure 7, the cup 34 does not deform when the removable container 12 is received in the outer shell 14, and only the shell 36 deforms, primarily at the reliefs 46. In this way, the appearance of reliefs on the lateral walls 35 of the cup 34, which may impair proper removal of the cosmetic product by creating pockets that are difficult to empty, is prevented.

[0069] Removal of the removable container 12 outside of the outer shell 14 can be accomplished, inter alia, by pulling on the flange of the removable container 12. In particular, blades and / or claws can be placed between the flange of the removable container 12 and the edge 24 of the outer shell 14 to facilitate the handling of the removable container 12 required for removal outside of the outer shell 14.

[0070] Additionally, as particularly shown in Fig. 3 or 6, the removable container 12 may further include an inner seal 48 that closes the outlet 41 of the cup 34 before its first use, preferably impermeable to liquids and more preferably to gases. In particular, the removable container 12 may include such an inner seal 48 in the packaging device 10 before its first use, or in a refill 100 of the cosmetic product P that includes such a removable container 12 closed by the inner seal 48 and received in a sealed package 102. According to a first example, the package 102 may be sealed to be impermeable to liquids, preferably to gases. Alternatively, the package 102 may be a preferably molded cellulose or paperboard packaging, particularly a case.

[0071] The inner seal 48 is, for example, made of aluminum or an aluminum alloy, of a plastic material, in particular polyethylene terephthalate (or PET) or polyethylene furanoate (or PEF), or else of paper, in particular coated paper.

[0072] 3, the inner seal 48 can be covered on at least one lower surface 48A, intended to be oriented toward the cosmetic product contained in the cup 34, with an impermeable coating 50, in particular a coating impermeable to liquids and preferably to gases. The coating 50 contains, for example, an epoxy resin and a methacrylate olefin polymer. The coating 50 here preferably has the dual function of protecting the cosmetic product by preventing direct contact of the cosmetic product with the inner seal 48, while allowing or even supporting the fixation of the inner seal 48 onto the cup 34, in particular by welding or bonding.

[0073] The inner seal 48 is preferably flexible, particularly more flexible than the cup 34. The inner seal 48 may be stretched over the outlet 41 of the cup 34, for example.

[0074] The inner seal 48 is preferably fixed to the flange 40 by a fixing region 49. The fixing region 49 corresponds to only the portion of the surface of the flange 40 of the cup 34 that is covered by the film 38. The fixing region 49 has, for example, an annular shape. The width of the fixing region 49 can be greater than or equal to 1 mm and / or less than or equal to 5 mm, in particular equal to 2 mm. The inner seal 48 is, for example, welded, in particular ultrasonically welded, to the flange 40 over the fixing region 49. The inner seal 48 can extend beyond the flange 40 of the cup 34, in particular by forming a tab 51 thereon, which is free compared to the cup 34. This tab 51 can facilitate gripping and handling of the inner seal 48, in particular for removing the inner seal 48 from the cup 34.

[0075] In order to limit the risk of peeling of the film 38 during this removal of the inner seal 48 from the cup 34, the flange 40 of the cup 34 presents a shape adapted to embed the film 38 with the inner seal 48 and thus limit or even negate the tangential stresses exerted by the inner seal 48 on the film 38 covering the cup 34 during removal of the inner seal 48, which tend to peel the film 38 from the cup 34.

[0076] 8, the flange 40 of the cup 34 thus exhibits a thinned portion 52 in the form of an outer annular portion of reduced thickness, in particular compared to the inner annular portion of the flange 40. Here, for example, the thinned portion 52 is formed by an outer portion, the thickness of which is substantially half the thickness of the remaining portion of the flange 40. Alternatively or additionally, the thickness of the outer portion forming the thinned portion 52 is between 0.2 mm and 0.5 mm, in particular equal to 0.365 mm. Here, the thinned portion 52 extends to the free outer edge 40e of the flange 40. In this case, the flange 40 of the cup 34 also includes a transition portion 53 of variable thickness, in particular a transition portion 53 of greater thickness, here having a substantially frustoconical shape, between the reduced-thickness portion 52 and a lower portion, the thickness of which decreases towards the outer edge 40e of the flange 40. At this transition portion 53, the securing force of the barrier film 38 against the flange 40 tends to counteract the pulling force applied to the barrier film 38 by the inner seal 48 when the inner seal 48 is removed from the cup 34, limiting or even preventing the risk of peeling of the barrier film 38.

[0077] To facilitate the manufacture of the removable container 12, the flange 44 of the shell 36 may also include a thinned portion 54 in the form of a section of reduced thickness. The thinned portion 54 of the flange 44 of the shell 36 may be located at the same level as the thinned portion 52 of the flange 40 of the cup 34. In fact, the thinned portions 52, 54 of the flanges 40, 44 may be formed simultaneously by pinching when the cup 34 is secured within the shell 36. Also in this case, the thinned portion 54 forms a transition section 53, the thickness of which decreases towards the outer edge 40e of the flange 40, which, as previously explained, can limit the risk of peeling of the barrier film 38 during removal of the inner seal 48.

[0078] It should be noted here that the thickness of the barrier film 38 covering the inner surface 34A of the cup 34 and here the upper free surface of the flange 40 can be substantially constant over the entire flange 40 of the cup 34, and that the pinching described above has substantially no effect on the barrier film 38. The thickness of the barrier film is, for example, between 0.1 mm and 0.5 mm, in particular equal to 0.2 mm.

[0079] 9, the thinned portion 52 of the flange 40 is spaced away from the free outer edge 40e of the flange 40. Thus, the thinned portion 52 of the flange 40 can form a groove on the free surface of the flange 40 of the cup 34.

[0080] Here, the grooves can be formed on the flange 40 of the cup 34 prior to fixation of the cup 34 in the shell 36. Thus, the shell 36 may lack a thinned portion 54 of the flange 44 that is flush with the thinned portion 52 of the flange 40 of the cup 34.

[0081] It should be noted that in the two cases (from FIGS. 8 and 9), the thinned portion 52 is arranged radially outward compared to the fixing area 49 of the inner seal 48 on the flange 40 .

[0082] 10 shows a second example of a removable container 12, which differs from the first example described above in that the shell 36 is covered on the inner surface 36A by a barrier film 56. The barrier film 56 is preferably impermeable to liquids, and more preferably to gases. Thus, the barrier film 56 can further reduce the risk of migration of ingredients from the cosmetic product P contained in the removable container 12 through the cup 34 and shell 36. The barrier film 56 can be similar to or even identical to the barrier film 38 covering the inner surface 34A of the cup 34.

[0083] 10, the flanges 40, 44 of the cup 34 and the shell 36, respectively, do not exhibit thinned portions 52, 54. However, the flanges 40, 44 may exhibit thinned portions 52, 54 as shown in FIG. 8 or FIG. 9.

[0084] Finally, Figures 11 and 12 show variants of Figures 8 and 9, respectively, in which the removable containers 12 each consist of a single cup 34. In other words, each removable container 12 shown in Figures 11 and 12 lacks a shell 36. In this case, the cup 34 presents a relief 46 adapted to elastically and / or plastically deform to maintain the removable container 12 on the outer shell 14. The relief 46 is then similar to that formed on the shell 36, as described above. Also in this case, the relief 46 deforms during insertion of the removable container 12 into the outer shell 14.

[0085] In this case, however, the cup 34 may be similar to the cup 34 from the previous example, but may exhibit a substantially greater thickness. Thus, in particular, the thickness of the layer of cellulose-based material may be substantially constant over the majority of the cup 34. The thickness of the layer of cellulose-based material may in particular be 0.5 mm or more, preferably 0.8 mm or more, and / or 1.6 mm or less, preferably 1.5 mm or less. The thickness of the layer of cellulose-based material may alternatively vary. In particular, the thickness of the layer of cellulose-based material may be reduced in the relief 46.

[0086] Additionally, as shown, the cup 34 of each removable container 12 shown in Figures 11 and 12 can have a flange 40 with a thinned portion 52 identical to the thinned portion 52 present on the flange 40 of the cup 34 from the previous example.

[0087] The invention is not limited solely to the embodiments described above with reference to the figures, but is on the contrary subject to numerous variants accessible to those skilled in the art, and in particular features of different embodiments described can be combined in embodiments not shown in the figures.

[0088] Furthermore, in the described example, the bottom of the removable container 12 is substantially flat. However, the bottom of the removable container 12 can have other forms. In particular, the bottom can exhibit reliefs, such as pins, that do not allow the removable container to be placed flat on a flat support. Such pins are then required to use the outer shell 14 to receive the removable container 12, in particular so that the removable container 12 can be used to collect the cosmetic product contained in the removable container 12 by preventing it from tipping over. According to another variant, the bottom of the removable container is rounded. [Explanation of symbols]
