Description

[0001] The present invention relates to the field of packaging of cosmetic products.

[0002] The term "cosmetic product" is particularly understood in the meaning of the present invention as meaning the products defined in Regulation (EC) No. 1223 / 2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products.

[0003] More particularly, the packaging and dispensing assembly according to the present invention is intended for dispensing a cosmetic product, for example an anhydrous product, in the form of a compacted powder, intended to be applied to the cutaneous surface of a user, for example.

[0004] Such a cosmetic product packaging assembly can for example be in the form of a box comprising a container delimiting an internal cavity and a lid hinged to the container between a position closing the box, in which the lid cooperates with the container to close the internal cavity, and a position opening the box, in which the lid is spaced apart from the container to release access to the internal cavity.

[0005] It is known practice to equip such a packaging assembly with a support member intended to receive at least one cosmetic product. The support member is mounted in the internal cavity of the container and forms an insert arranged in the container. This design, comprising a container and a support member separate from one another, makes it possible to use two different materials for these elements, so that the container / support member assembly can provide its expected mechanical and aesthetic functions, while having the best manufacturing cost.

[0006] The known product packaging assemblies are not entirely satisfactory in terms of weight.

[0007] There is therefore a need to provide a device for packaging a cosmetic product that is lighter than the known packaging devices, while maintaining a satisfactory rigidity of the device.

[0008] In particular, making the cosmetic product packaging device lighter is an important consideration during its design, not only in order to reduce the amount of material, in particular plastic material, used to manufacture the device, thereby reducing its manufacturing cost, but also in order to reduce the resources and energy required for its manufacture, transport and recyclability, thereby also addressing the problem of reducing its ecological impact during its lifetime.

[0009] However, this objective must be reconciled with the need to ensure the integrity and structural rigidity of these new generations of cosmetic product packaging devices, at least comparable to the previous generations of cosmetic product packaging devices.

[0010] The subject of the present invention is a device for packaging a product, in particular a cosmetic product, comprising:

[0011] - a container extending along an elevation axis and comprising an internal volume delimited by a lower wall and a peripheral wall;

[0012] - a lid hinged with respect to said container between a closed position in which it cooperates with the container and closes the access to the internal volume of said container and an open position in which it is pivoted away from the container to allow access to said internal volume; and

[0013] - a support member mounted in the internal cavity of the container and intended to receive at least one cosmetic product, the support member comprising an internal volume delimited by a bottom wall and a peripheral wall.

[0014] One of the support member or the container further comprises at least one reinforcing member extending along the elevation axis from one of the support member or the container towards the other of the support member or the container and fastened to the other of the support member or the container.

[0015] In other words, either the support member comprises a reinforcing member extending towards the container or the container comprises a reinforcing member extending towards the support member.

[0016] By means of the reinforcing member, it is possible to significantly reduce, in particular the thickness of the support member and / or of the container, but more particularly the thickness of the container, when the reinforcing member is fastened to the support member, thereby reducing the weight and the quantity of material used to manufacture the product packaging device while maintaining the constant rigidity of the assembly formed by the container and the support member.

[0017] The weight reduction observed is between 15% and 40% compared to a packaging device having no reinforcing member between the product support member and the container.

[0018] One of the support member or the container comprises at least a partial peripheral protrusion extending along the elevation axis towards the other of the support member or the container and fastened to the other of the support member or the container.

[0019] In other words, the support member can comprise a peripheral protrusion extending towards the container or the container can comprise a peripheral protrusion extending towards the support member.

[0020] It is also possible to provide that the support member comprises a peripheral protrusion and the container comprises a reinforcing member, or vice versa.

[0021] For example, the reinforcing member is surrounded by the peripheral protrusion.

[0022] According to one embodiment, the support member comprises at least a partial peripheral protrusion which extends in a continuation of the peripheral wall along the elevation axis towards the lower wall of the container and is fastened to said lower wall, in particular to the upper surface of the lower wall, and the reinforcing member is surrounded by the peripheral protrusion. Said reinforcing member extends from the bottom wall of the support member along the elevation axis towards the lower wall of the container and is fastened to said lower wall. In this way, a mechanical connection is obtained between said support member and said container.

[0023] Thus, by establishing a mechanical connection between at least a partial peripheral protrusion of the support member and at least one reinforcing member of the support member and the lower wall of the container, in particular integral with the bottom wall of the support member, the support member is fastened to the container.

[0024] The fact that the peripheral protrusion and the reinforcing member are provided on the support member makes it possible to avoid forming shrink marks on the visible part of the device, that is to say the part that can be seen from the outside of the device, which are liable to appear at the junction of the two, in particular orthogonal, sections of the injection-moulded plastics part. Thus, these possible shrink marks are transferred onto the support member, more particularly onto the upper surface of the support member which is intended to be hidden from the user, rather than onto the container which preferably has a high-quality appearance.

[0025] Furthermore, in this configuration, the quality savings obtained in the assembly formed by the support member and the container are mainly achieved in the container, the quality of the constituent material of which is higher than that of the constituent material of the support member, and the density of the constituent material of which is generally higher. This makes for economic savings and ecological improvements.

[0026] Advantageously, the reinforcing member and / or the at least partial peripheral protrusion are integral with the support member. In other words, the reinforcing member and / or the at least partial peripheral protrusion and the support member form a single part produced during the moulding step.

[0027] For example, the reinforcing member is fixed to the container by ultrasonic welding. As a variant, any other fixing means can be provided, such as adhesive bonding or laser welding.

[0028] For example, the peripheral protrusion is fixed to the container by ultrasonic welding. As a variant, any other fixing means can be provided, such as adhesive bonding or laser welding.

[0029] According to one embodiment, the reinforcing member comprises at least one central protrusion.

[0030] For example, the central protrusion has a closed profile or an open profile.

[0031] According to one embodiment, the reinforcing member comprises at least one radial projection.

[0032] The radial projection is arranged, for example, between the central projection and the peripheral projection. A plurality of radial projections can be provided, for example, regularly or irregularly spaced around the central projection. As a variant, different arrangements of radial projections around the central projection can be provided. As illustrated, the number of radial projections is equal to 12. As a variant, a different number of radial projections can be provided, for example, more than two. The radial projections can all be provided with the same or different dimensions.

[0033] According to one embodiment, the reinforcing member comprises at least one intermediate projection arranged between the central projection and the peripheral projection.

[0034] According to one embodiment, the reinforcing member comprises at least one radial projection between the central projection and the intermediate projection and / or at least one radial projection between the intermediate projection and the peripheral projection.

[0035] The intermediate projection can be concentric with the central projection.

[0036] The intermediate projection has a closed contour or an open contour. As a variant, an intermediate projection having a closed contour can be provided. As a variant, an intermediate projection having a contour identical to that of the central projection can be provided.

[0037] Advantageously, the thickness of the lower wall of the container is between 0.5 mm and 0.9 mm, for example equal to 0.7 mm.

[0038] For example, the thickness of the bottom wall of the support member is between 0.65 mm and 0.75 mm, for example equal to 0.7 mm.

[0039] For example, the thickness of the peripheral wall of the container is between 0.75 mm and 0.85 mm, for example equal to 0.82 mm.

[0040] For example, the internal volume of the support member is intended to receive a tray comprising at least one compartment of cosmetic product. As a variant, it can be provided that the cosmetic product is contained directly in the support member.

[0041] The support member can comprise an upper rim or bearing flange radially projecting from the upper surface of the peripheral wall of said support member.

[0042] For example, the support member also comprises positioning ribs projecting from the lower surface of the rim towards the container along the elevation axis.

[0058] Figures 1 to 4 illustrates a device 1 for packaging products.

[0059] "Product" refers to cosmetic products, such as finely ground, dense solid products in the form of a dense powder, intended for application to, for example, a user's skin. Dense powder can be a type of foundation, face powder, or eyeshadow, and can be picked up directly with fingers, a powder puff, or a brush.

[0060] In the remainder of the instruction manual, reference will be made to the standard orthogonal basis X, Y, Z, where Z corresponds to the elevation axis representing the vertical direction. Figure 2 and Figure 3 The intermediate section M is the plane of symmetry (Y, Z) of container 10.

[0061] Device 1 is a cosmetic box type and includes a container 10, a lid 20, and a support member 30, the lid being positioned relative to the container 10. Figure 2 The visible closing position and Figure 3 The support member is hinged between the visible open positions and is designed to receive at least one cosmetic product.

[0062] Container 10 includes a body with an overall parallelepiped shape, which extends along an elevation axis Z-Z' assumed to be vertical in the figure. The body can be provided with any other shape, such as a cylinder.

[0063] The body of container 10 includes an internal volume 11 for receiving cosmetic products. The internal volume 11 is defined by a lower wall 12 or bottom, two side walls 13, a front wall 14, and a rear wall 15. The lower wall or bottom is substantially flat and arranged in a plane XY containing a longitudinal axis X and a transverse axis Y. The side walls 13, front wall 14, and rear wall 15 form a generally square or rectangular outline. Other regular or irregular outline shapes are also possible, particularly circular, polygonal, or elongated shapes.

[0064] like Figure 3 As shown, the thickness e1 of the lower wall 12 of the container is between 0.5 mm and 0.9 mm, for example, equal to 0.7 mm.

[0065] like Figure 3 As shown, the thickness e2 of the outer wall of the container 10, which is formed by the side wall 13, the front wall 14 and the rear wall 15, is between 0.75 mm and 0.85 mm, for example, equal to 0.82 mm.

[0066] The lid 20 is hinged to the container 10, particularly to the rear 15, the hinge including the same rotating pin 16 parallel to the longitudinal axis X. The lid 20 includes an internal volume 21 defined by an upper wall 22, two side walls 23, a front wall 24, and a rear wall 25.

[0067] The rear wall 25 of the cover is rotatably mounted on the rotating pin 16.

[0068] The front wall 24 of the lid 20 comprises a retention member 26 which, in the closed position of the lid, projects in a continuation of said front wall along a vertical axis Z. The retention member 26 is intended to cooperate, for example by snap fit, with a corresponding retention member 17 of the container 10, in order to retain the lid on said container in the closed position of said lid.

[0069] The lid 20 is movable between a closed position, illustrated in Figure 1 and Figure 2 an open position, illustrated in Figure 3 in which the lid 20 is pivoted about the pin 16 away from the container, to allow access to the internal volume 11.

[0070] In the closed position, the lid 20 is arranged above the container 10.

[0071] The support member 30 is mounted in the internal cavity 11 of the container 10 and forms a removable insert or replacement in order to replace or change the cosmetic product once it is finished.

[0072] Because the support member 30 is separate from the container 10, two different materials can be used, namely a first material for the container 10 and a second material for the support member 30. The quality of the second material is lower than the quality of the material of the container 10. Thus, the density and therefore the price of the second material can be lower than the density and therefore the price of the first material, making it possible to obtain a support member which is cheaper and lighter than the container 10. The support member 30 comprises an internal volume 31 for receiving, for example, a cosmetic product 40 contained in a tray. As illustrated, the tray 40 comprises a single compartment of cosmetic product. As a variant, a tray with a plurality of compartments can be provided, each containing a cosmetic product. It is also possible to provide that the cosmetic product is contained directly in the support member 30.

[0073] The internal volume 31 is delimited by a bottom wall 32 and a peripheral wall 33 forming a closed profile.

[0074] The support member 30 comprises an upper rim or bearing flange 34 projecting radially from the upper surface of the peripheral wall 33. The upper rim 34 is intended to be mounted inside the internal cavity 11 of the container 10.

[0075] In a completely non-limiting manner, the bottom wall 32 comprises a central protrusion or boss 32a extending from the upper surface of the bottom wall 32 towards the tray 40. Such a protrusion is generally produced during moulding, for example injection moulding, of the material used to form the support member 30.

[0076] As illustrated, and in a completely non-limiting manner, the tray 40 is fixed to the bottom wall 32 of the support member 30 by adhesive bonding, for example by means of an adhesive film 35 arranged on the central boss 32a.

[0077] As illustrated, the thickness e3 of the bottom wall 32 of the support member 30 is between 0.65 mm and 0.75 mm, for example equal to 0.7 mm.

[0078] The support member 30 also comprises positioning ribs 36 which project from the lower surface of the rim 34 towards the container 10 along the vertical axis Z.

[0079] As can be seen in detail in Figure 6 and Figure 8 , the support member 30 comprises a peripheral protrusion 37 which extends in a continuation of the peripheral wall 33 along the vertical axis Z towards the lower wall 12 of the container 10. The lower end of said peripheral protrusion 37 is mechanically fixed or fastened to the upper surface of the lower wall 12 of the container, for example by ultrasonic welding.

[0080] As a variant, the peripheral protrusion can be part of the container 10 and extends along the elevation axis towards the support member 30.

[0081] The support member 30 also comprises a first central protrusion 38 having a closed contour which extends from the lower surface of the bottom wall 32 of the support member 30 towards the upper surface of the lower wall 12 of the container along the vertical axis Z. The lower end of said first central protrusion 38 is mechanically fixed to the upper surface of the lower wall 12 of the container, for example by ultrasonic welding. As a variant, a central protrusion having a non-closed contour can be provided.

[0082] The support member 30 also comprises a plurality of radial protrusions 39 arranged between the central protrusion 38 and the peripheral protrusion 37 and extending from the lower surface of the bottom wall 32 of the support member 30 towards the upper surface of the lower wall 12 of the container along the vertical axis Z. The lower end of each of said radial protrusions 39 is mechanically fixed to the upper surface of the lower wall 12 of the container, for example by ultrasonic welding. As illustrated, the radial protrusions 39 are regularly spaced around the central protrusion 38. As a variant, a different arrangement of the radial protrusions around the central protrusion 38 can be provided. As illustrated, the number of radial protrusions 39 is equal to 12. As a variant, a different number of radial protrusions can be provided, for example more than two. In a completely non-limiting manner, in this case, four first radial protrusions have the same size and four second radial protrusions have the same size, but smaller than the size of the first radial protrusions. As a variant, the radial protrusions can all have the same or different sizes.

[0083] In particular Figure 6 and Figure 8In the illustrated embodiment, the radial protrusion 39 extends radially between the central protrusion 38 and the peripheral protrusion 37, but is not connected to them. Each end of the radial protrusion 39 has a radially spaced distance between it and the central protrusion 38 on one side and the peripheral protrusion 37 on the other side. This configuration may be particularly advantageous when the support member 30 is fixed to the container 10 by ultrasonic welding, where unstable material behavior is prone to occur at the junction between the radial protrusion and the central and / or peripheral protrusions if the radial protrusion is connected to the central protrusion 38 and / or the peripheral protrusion 37 during this process.

[0084] As a variation, one, another, or all of the radial protrusions 39 may be provided to engage with the central protrusion 38 and / or the peripheral protrusions 37 in the radial direction. This configuration may be particularly advantageous when the support member is fixed in the container by adhesive bonding.

[0085] Alternatively, only radial protrusions can be set without central protrusions, or as a variant, only central protrusions can be set without radial protrusions.

[0086] As a variation or supplement, a central protrusion and / or one or more radial protrusions may also be provided as part of the container 10 and extend along the elevation axis toward the support member 30.

[0087] The peripheral protrusion 37, the central protrusion 38, the radial protrusion 39, and the support member are formed into a single piece from a single material during a single molding operation.

[0088] exist Figure 13 In the illustrated embodiment, the same elements have the same reference numerals, and the support member 30' and Figures 2 to 12 The only difference in the support member 30 shown is the shape and arrangement of the reinforcing member.

[0089] As shown in the figure, the support member 30' includes a peripheral protrusion 37 extending along the vertical axis Z toward the lower wall 12 of the container 10 in a continuation of the peripheral wall 33. The lower end of the peripheral protrusion 37 is mechanically fixed to the upper surface of the lower wall 12 of the container, for example by ultrasonic welding.

[0090] The support member 30' also includes a central protrusion 38a and an intermediate protrusion 38b coaxial with the central protrusion 38a. Both protrusions have closed profiles and extend along the vertical axis Z from the lower surface of the bottom wall 32 of the support member 30 toward the upper surface of the lower wall 12 of the container. The lower ends of the central protrusion 38a and the intermediate protrusion 38b are mechanically fixed to the upper surface of the lower wall 12 of the container, for example, by ultrasonic welding. As a variation, the central protrusion may not have a closed profile. A different number of central protrusions may also be provided, for example, more than or equal to three.

[0091] The support member 30' also includes a plurality of first radial protrusions 39a arranged between a first central protrusion 38a and an intermediate protrusion 39b, and a plurality of second radial protrusions 39b arranged between the intermediate protrusion 38b and the peripheral protrusion 37. The radial protrusions 39a and 39b extend along the vertical axis Z from the lower surface of the bottom wall 32 of the support member 30' toward the upper surface of the lower wall 12 of the container. The lower end of each of the radial protrusions 39a and 39b is mechanically fixed to the upper surface of the lower wall 12 of the container, for example, by ultrasonic welding. As shown, the radial protrusions 39a and 39b are regularly spaced around the corresponding central protrusions 38a and 38a. As a variation, different arrangements of the radial protrusions around the corresponding central or intermediate protrusions 38a and 38b can be provided. As shown, the number of first radial protrusions 39a is equal to four, and the number of second radial protrusions 39b is equal to four. As a variation, different numbers of radial protrusions can be provided, for example, more than two. In a completely non-limiting manner, the radial protrusions in this case have the same dimensions. As a variation, the radial protrusions can be configured to have the same or different dimensions.

[0092] The peripheral protrusion 37, the central protrusion 38a, the intermediate protrusion 38b, the radial protrusions 39a, 39b and the support member 30' are formed into a single piece from a single material during a single molding operation.

[0093] exist Figure 14 In the illustrated embodiment, the same elements have the same reference numerals, and the support member 30” and Figures 2 to 12 The only difference in the support member 30 shown is the shape and arrangement of the reinforcing member.

[0094] As shown in the figure, the support member 30” includes a peripheral protrusion 37 extending along the vertical axis Z toward the lower wall 12 of the container 10 in a continuation of the peripheral wall 33. The lower end of the peripheral protrusion 37 is mechanically fixed to the upper surface of the lower wall 12 of the container, for example by ultrasonic welding.

[0095] The support member 30” also includes a central protrusion 38 having a closed profile, extending along the vertical axis Z from the lower surface of the bottom wall 32 of the support member 30” toward the upper surface of the lower wall 12 of the container. The lower end of the central protrusion 38 is mechanically fixed to the upper surface of the lower wall 12 of the container, for example by ultrasonic welding. As a variation, the central protrusion may not have a closed profile. A different number of central protrusions may also be provided, for example, more than or equal to two.

[0096] The support member 30” also includes a central protrusion 40 with a closed profile, which extends along the vertical axis Z from the lower surface of the bottom wall 32 of the support member 30” toward the upper surface of the lower wall 12 of the container, surrounding the central protrusion 38, and is mechanically fixed to the upper surface of the lower wall 12 of the container, for example by ultrasonic welding. As shown, the central protrusion 40 has a polygonal shape.

[0097] The support member 30” also includes a plurality of radial protrusions 39 having a closed profile, which are arranged between the central protrusion 40 and the peripheral protrusions 37. The radial protrusions 39 extend along the vertical axis Z from the lower surface of the bottom wall 32 of the support member 30” toward the upper surface of the lower wall 12 of the container. The lower end of each radial protrusion 39 is mechanically fixed to the upper surface of the lower wall 12 of the container, for example by ultrasonic welding. As shown, the radial protrusions 39 are regularly spaced around the corresponding central protrusion 38.

[0098] exist Figure 14 In the exemplary embodiment shown, the radial protrusion 39 has a closed profile and is connected to the intermediate protrusion 40. In this case, the radial protrusion 39 is generally U-shaped, and the free ends of the U-shaped legs are connected together through a portion of the intermediate protrusion 40 to form a closed profile.

[0099] As a variation, the radial protrusion 39 can be set to be approximately U-shaped, with the free ends of the U-shaped legs not connected together, thus forming a non-closed profile.

[0100] The peripheral protrusion 37, the central protrusion 38, the radial protrusion 39, the intermediate protrusion 40, and the support member 30” are formed into a single piece from a single material during a single molding operation.

[0101] Generally, the box 1 includes a reinforcing member formed by at least one protrusion extending along a vertical axis Z from the bottom wall of the support member toward the lower wall of the container and mechanically fixed to the lower wall to form a mechanical connection between the support member and the container.

[0102] According to the present application, in particular the reinforcing ribs, it is possible to significantly reduce the wall thickness of the container and of the support members, thus reducing the overall weight of the product packaging device.
