Description

Cosmetic product packaging assembly comprising a wringing member

The present invention relates to a set of packaging and application of cosmetic product, of the type comprising: a container comprising a body defining an internal volume for containing said cosmetic product, a wall of said body comprising an opening opening on said internal volume; and a wringing member, comprising a tubular shaped assembly skirt, said assembly skirt being inserted through the opening of the container.

By "cosmetic product" is meant in the sense of the present invention a product as defined in the Regulation (EC) No. 1223/2009 of the European Parliament and the Council dated November 30, 2009, relating to cosmetics.

The cosmetic product for which the assembly according to the invention is intended is in particular in the form of a powder, of a compacted solid, or preferentially of a fluid such as a liquid. The product is advantageously a product intended to be placed on the keratin fibers of a user, such as the eyelashes or the eyebrows. The product is for example a makeup product such as a mascara.

It is known to present a makeup product such as a mascara in a packaging assembly of the aforementioned type comprising an outer collar extending the opening. Such packaging assemblies are described in particular in the documents FR2504788, EP1561394 and EP0829211. The packaging assembly is intended to be used with an application member. The applicator member is introduced through the neck into the tank where it is loaded with cosmetic product before being extracted from said reservoir to proceed with the application. The packaging assembly is equipped with a wiper member to remove excess cosmetic product and adjust the load of the applicator member. The wiper member is generally disposed in the neck of the container.

More specifically, when an applicator is introduced into the container for taking cosmetic product, then extracted from the container by the neck, the wiper member holds in the container a portion of the cosmetic product coating the applicator. This avoids taking too much product, which facilitates its application. Generally, as described in the aforementioned documents, the wiper member comprises an assembly skirt, of flexible material, substantially tubular in shape, inserted into the neck of the container. In order to guarantee a sufficiently solid assembly, manufacturing practices impose a minimum axial length of the assembly skirt, said skirt being in contact with the neck over the entire length.

As a standard, a wiper has a hooking height greater than 10 mm, generally about 11.40 mm. The standard internal height of a container neck is substantially equal to the attachment height.

This minimum axial length consequently imposes a corresponding minimum height of the neck. The design possibilities of the container are thus limited.

There is therefore a need for a simple solution for varying the design of the container while allowing a solid assembly of said container with the wiper member. For this purpose, the subject of the invention is a packaging assembly of the aforementioned type, in which the receptacle comprises an inner sleeve extending projecting inside the internal volume from the opening, at least partially defining a internal assembly wall, of substantially complementary shape of an outer lateral surface of the assembly skirt, said assembly wall coming into contact with said outer lateral surface.

Figure 1 shows a set 10 of packaging and application of cosmetic product, including mascara. The assembly 10 comprises in particular an applicator 12, a container 14 and a wiper 15. The applicator 12 comprises a rod 16 extending along a first substantially longitudinal axis 18. The rod 16 has a first end connected to a gripping member 20 and an opposite second end carrying a head or applicator member 22.

The application head 22 is typically a mascara brush or comb. More particularly, the application head 22 comprises a main body 24, or core, of elongate shape. Preferably, the application head 22 extends in the extension of the rod 16, substantially along the axis 18. The application head 22 further comprises a plurality of reliefs or application elements 26, of the hair type or pins, extending laterally projecting from the main body 24.

According to one embodiment, the application head 22 is for example a brush comprising a twisted core, formed by a twisted and U-shaped wire, the bristles being held and clamped between the turns of the core. According to another embodiment, the application reliefs are overmolded on the core.

The applicator head 22 has a transverse dimension passing through at least one maximum value along the axis 18. The applicator 12 further comprises a means of assembly with the container 14. In the embodiment shown in FIG. Figure 1, the applicator 12 comprises a ring 32 secured to the first end of the rod 16 and disposed around said end, along the axis 18. The ring 32 has a thread 34 adapted to cooperate with a thread of the container 14 as described below.

The container 14 is disposed along a second axis 36 and comprises in particular a main body 38. The body 38 has a side wall 40, a bottom 42 and an upper wall 44, which define an internal volume 46 adapted to receive a cosmetic product, particularly a liquid.

In the present description, the terms such as "superior" or "inferior" are understood by considering that the bottom 42 of the container 14 rests on a horizontal support, the second axis 36 representing the vertical.

In the embodiment shown in FIGS. 1 and 2, the container 14 is substantially symmetrical with respect to the axis 36. In the vicinity of the upper wall 44, the side wall 40 has a first internal diameter 48.

The upper wall 44 has an axial opening 50. The container 14 further comprises an outer neck 52, of tubular shape, which axially extends the body 38 from the axial opening 50. The neck 52 is more particularly visible in FIG. 2.

At the level of said axial opening 50, the neck 52 has a second internal diameter 54, smaller than the first internal diameter 48. The upper wall 44 of the body 38 forms a shoulder between the neck 52 and the side wall 40.

An outer wall of the neck 52 has a thread 56 adapted to cooperate with the tapping 34 of the applicator 12 to assemble the applicator 12 and the container 14 in a storage configuration as shown in Figure 1. In said storage configuration the first 18 and second 36 axes coincide, the applicator 12 closes the container 14 and the application head 22 is received in the internal volume 46.

The container 14 further comprises an inner sleeve 60 extending the outer neck 52 along the second axis 36, inside the internal volume 46. The inner sleeve 60 is disposed around the axial opening 50 and protrudes from the upper wall 44, towards the bottom 42.

The outer collar 52 and the inner sleeve 60 define an inner wall 62 of assembly, preferably having a shape substantially of revolution about the axis 36. More preferably, the inner wall 62 is substantially cylindrical of revolution, of internal diameter 54 In a variant not shown, the inner wall 62 has a slightly frustoconical shape, tapered towards the bottom 42.

The inner wall 62 preferably forms a continuous surface, the inner sleeve 60 having the shape of a ring. In a variant not shown, the inner wall 62 forms a partially discontinuous surface, the inner sleeve being formed for example by tabs slightly spaced from each other and arranged around the axial opening 50.

Between an upper end 64 of the neck and a lower end 66 of the sleeve, the inner wall 62 has a first height 68 along the axis 36. Furthermore, between the upper end 64 and the upper wall 44 of the body 38, a surface external of the neck has a second height 70, lower than the first height 68.

In the embodiment shown in Figures 1 and 2, the inner wall 62 has a groove 72 disposed near the upper end 64 of the neck. The wiper member 15 is assembled to the container 14, in particular to the neck 52 and to the sleeve 60, as can be seen in FIG. 1. The wiper member 15 is shown in dissociated form in FIG. de-wringing device 15 is able to retain in the internal volume 46 a portion of the cosmetic product coating the application head 22 when said applicator head 22 is extracted from the container 14 from the storage configuration shown in FIG.

In the embodiment shown in Figures 1 and 2, the wiper member 15 has a tubular shape, preferably substantially of revolution about the axis 36, defining an axial passage 80. In the storage configuration, the rod 16 of the applicator 12 is received in the axial passage 80. The wiper member 15 has a wiper skirt 82 and an assembly skirt 84, adjacent along the axis 36.

The wiper skirt 82 is disposed inside the internal volume 46 of the container 14 and protrudes from the upper wall 44 towards the bottom 42. The wiper skirt 82 has a substantially frustoconical, tapered shape. towards the bottom 42, in the direction opposite to the assembly skirt 84.

A lower end opening of the wiper skirt 82 has an inner diameter 86 less than the maximum diameter of the application head 22. Thus, when the applicator head 22 is extracted from the container 14 from the storage configuration , the application reliefs 26 rub on the edge of the wiper skirt 82 and are thus freed of a portion of the product which covers them.

The assembly skirt 84 is intended to come into contact with the inner assembly wall 62 of the container 14, as can be seen in FIG. 1. An external lateral surface 90 of the assembly skirt 84 has a shape substantially complementary to said internal wall 62. Preferably the outer lateral surface 90 has a shape substantially of revolution about the axis 36, more preferably cylindrical of revolution, of external diameter substantially equal to the internal diameter 54 of the inner wall 62.

Similarly, the outer lateral surface 90 has a height along the axis 36 substantially equal to the first height 68 of the inner wall 62. Said height 68 is provided so as to ensure a sufficient contact surface to a solid assembly between the wall 62 and the assembly skirt 84. At a first end of the assembly skirt 84, opposite to the wiper skirt 82, the wiper member 15 comprises a rim 92 in the form of a crown, forming a protrusion radial to the outer lateral surface 90. The flange 92 is supported on the upper end 64 of the neck. At a second end of the assembly skirt 84, at a junction with the wiper skirt 82, the wiper member 15 has an annular bead 94, forming a radial projection relative to the external lateral surface. 90. The annular bead 94 rests on the lower end 66 of the sleeve.

Thus, the wiper member 15 is locked axially with respect to the inner assembly wall 62, the flange 92 and the bead 94 forming opposed stops, respectively against the neck 52 and against the sleeve 60.

According to a variant not shown, the rim 92 and / or the continuous bead 94 are replaced by notches projecting radially with respect to the external lateral surface 90.

In the embodiment shown in Figures 1 and 2, the wiper member 15 further comprises a radial rib 96 projecting from the outer lateral surface 90. The radial rib 96 is inserted into the groove 72 of the wall internal assembly 62, as visible in Figure 1.

Because of its function, the wiper skirt 82 is preferably made of a flexible and elastically deformable material such as an elastomer. More preferably, the wiper member 15 is entirely made of such a material, which facilitates its assembly with the container 14 as described below.

According to an alternative embodiment not shown of the wiper member 15, the wiper skirt 82 is replaced by another wiper means. For example, the wiper member 15 comprises pins forming a radial projection towards the inside of the passage 80, from the assembly skirt 84.

According to a not shown embodiment of the container 14, the opening 50 of the container is devoid of external neck 52, and the wiper member 15 comes into contact with the upper wall 44 at said opening 50.

A method of manufacturing the assembly 10 will now be described. The container 14 is made by injection molding, (can also be made by stamping, thermoforming, etc.) by means of a thermoplastic polymer such as PP / PE. With respect to a conventional container neck profile, without a protruding sleeve in the internal volume, a simple adaptation of the mold is necessary to predict the formation of the sleeve 60 in one piece with the neck 52.

The external height 70 of the neck 52 can be decreased relative to the known containers, insofar as the height 68 of the internal assembly wall 62 is sufficient for a solid connection with the wiper member 15. A wider choice is thus possible in the context of the design of the container 14, the neck can even be removed if the inner sleeve is of sufficient length.

Moreover, the wiper member 15 is made by injection molding, (may also be made by compression, etc.) for example by means of an elastomer. The wiper member 15 is then deformed and inserted into the container 14 by the neck 52, the wiper skirt 82 being introduced into the internal volume 46. The flange 92 and the bead 94 are respectively snap against the neck 52 and against the sleeve 60, and the radial rib 96 is inserted into the groove 72, axially locking the wiper member 15 relative to the container 14.

Optionally, the wiper member is secured to the container by an additional method of attachment, such as a glue or a chemical solder.

The internal volume 46 is then filled with cosmetic product and the container 14 is assembled to the applicator 12, in the storage position shown in Figure 1. When screwing the ring 32 on the neck 52, the flange 92 of the assembly member 15 is slightly compressed, fulfilling a sealing function. The assembly 10 can then be used by unscrewing the ring 32 from the neck 52 to extract the application head 22 from the internal volume 46, in order to apply cosmetic product to the user's keratin fibers using the Applicator 12. When extracting the application head 22 through the neck 52, the wiper skirt 82 retains in the internal volume 46 a portion of the product coating the application reliefs 26, which makes it possible to conserve on said reliefs only the amount of product necessary for makeup.
