Description

  The present invention relates to a device for packaging and applying a product, in particular a cosmetic or care product, in particular a cosmetic product, which device is to be applied. And an applicator capable of loading the product by immersion in the container.

  Such devices typically include a wiping member to adjust the amount of product on the applicator applicator member when the applicator is withdrawn from the container.

  Various wiping members have been proposed specifically to adapt the properties of the application member, the rheology of the product, and the desired cosmetic outcome.

  Therefore, in Patent Document 1 of the application document, there is a wiping member made of two materials including an upper part that functions to fix the wiping member to the neck of the container and a lower part that is made from different materials. Proposed, this lower part is more flexible than the upper part and includes a wiping lip.

  Patent document 1 of the published document further includes a wiping lip having a specific shape such as a corrugated shape or including a slot so that the coating member can be more easily deformed as it passes through. It has been proposed to generate.

  However, changing the deformability of the wiping lip, for example, to adapt to the various properties of the applicator member still remains relatively difficult.

  Patent Document 2 and Patent Document 3 disclose wiping lips made of a single material.

The present invention aims to further complete packaging and application devices, and in particular, wiping members that fit into such devices,
i. a container for the cosmetic product to be applied;
ii. An applicator for pulling out the product contained in the container, the applicator comprising an application member for applying the product;
A packaging and application device comprising:
The container includes a wiping member for wiping the application member when the application member leaves the container, the wiping member includes a flexible lip, and the free edge of the wiping lip is an orifice through which the application member passes. The wiping lip is deformed as the application member passes through the orifice, and the wiping lip extends in an angular manner about the orifice axis X and is composed of different rigid materials. This is achieved using a packaging and application device having at least one sector in at least one cross section.

  Depending on the configuration of these sectors, the presence of at least two sectors produced from materials having different hardnesses in the wiping lip gives the wiping lip more or less flexibility and thus The deformability characteristics can be adapted to the properties of the application member.

  Preferably, the wiping member has an upper portion that is made of a more rigid material, thereby enabling improved wiping member retention at the neck of the container to which it is attached.

One or more sectors of higher stiffness can occupy a greater angular range in the cross section about the axis X of the wiping orifice at height h ₂ than at height h ₁ , provided that h ₂ > h ₁ , the heights h ₁ and h ₂ are measured along the axis X from a right angle projection on the vertical axis X of its free edge, and the wiping orifice is at the bottom. In fact, since the wiping lip deformation is desirable in contact with the applicator, it is preferable to have a more flexible portion in contact with the applicator.

  Preferably, the one or more sectors of higher rigidity occupy at least one cross-section with a total angular range that is smaller than the total angular range occupied by one or more other sectors of the wiping lip. This helps to increase the deformability of the wiping lip.

  The wiping lip can have at least one sector made from the same material, and its angular range about the axis X in the cross section decreases in the direction of the free edge of the wiping lip. Such a shape makes it possible to further reduce the overall stiffness of the wiping lip close to the wiping orifice.

  Sectors made from different materials can extend to the free edge of the wiping lip. As a variant, the free edge of the wiping lip can be defined only by the same material, preferably by a less rigid material. The free edge comes into contact with the applicator member during wiping of the applicator member.

  The wiping member can comprise a tubular skirt that surrounds and is coaxial with the wiping lip. For example, the wiping orifice is positioned at the lower end of the wiping member or, as a variant, is retracted axially from the tubular skirt described above.

  The wiping lip can converge towards the wiping orifice, specifically having a shape that is generally conical or in the form of a dome. Therefore, specifically, when the applicator is reinserted into the container, passage through the wiping member can be made easier.

  Preferably, the various sectors are generated by double injection of the material or by overmolding one material to the other.

  Preferably, the number of sectors made from a more rigid material is between 2 and 5, specifically 3 or 4.

  For example, sectors made from different materials are securely held using local melting during double injection or overmolding manufacturing. Preferably, at least one mechanical attachment is created by matching the shapes with the help of cooperative undulations. This makes it possible to obtain a reliable attachment even if the material has chemical properties that make it difficult to join by melting.

  One of the sectors can be composed of an elastically deformable material, preferably a thermoplastic elastomer.

  Preferably, the material comprising the one or more sectors of lower rigidity is selected from among elastomers, specifically thermoplastic elastomers.

  Preferably, the material constituting the one or more sectors of higher rigidity is selected from among polyolefins.

  Preferably, the hardness difference between the stiffer material and the less stiff material is at least 20 on a single Shore hardness scale.

  The two materials of different stiffness can be from the same chemical family that may or may not be easily recycled.

  These materials can have different colors.

  Preferably, each sector extends over at least 0.5 mm around the wiping lip.

  In one exemplary embodiment, the container has a neck, and the wiping member has an upper portion provided with a flange that comes into contact with the upper side of the neck and the lip of the container beyond the wiping lip. A lower portion extending toward the bottom, wherein the upper portion and the lower portion are each made from different materials into a single piece by molding together with at least one of the sectors of the wiping lip, Produced.

  The invention also relates to a wiping member that is considered separately.

  The present invention may be better understood by reading the following detailed description of its non-limiting implementation examples and by examining the accompanying drawings.

FIG. 2 is an isolated axial sectional view showing the wiping member of the device from FIG. FIG. 3 is a front view along III from FIG. FIG. 3 is an isolated axial sectional view showing the upper part of the wiping member from FIG. FIG. 5 is a front view taken along arrow V in FIG. FIG. 5 is a view similar to FIG. 4 of a modified embodiment of the wiping member. FIG. 7 is a front view taken along arrow VII in FIG. FIG. 6 is a partial longitudinal cross-sectional view of a modified embodiment of a wiping member. It is the isolate | separated and perspective view which shows another deformation | transformation form of the wiping member.

  The packaging and application device 10 shown in FIG. 1 has a container 11 containing a product to be applied, for example a cosmetic or care product, and an application member 14 at one end An applicator 12 with a stem 13 provided at the other end of a member (not shown), this gripping member being attached to the neck 15 of the container 11, in particular by screwing A closure cap of the container 11 can also be constructed that is configured to be

  The container 11 is shown separated in FIG. 2 and comprises a wiping member 20 mounted in a neck 15. The wiping member 20 includes an upper portion 30 and a lower portion 40 made from different materials, preferably the upper portion 30 is made from a material that is more rigid than the lower portion 40. Advantageously, the upper portion 30 is provided with a flange 31 at its upper end so as to press against the end face 16 of the neck 15 as shown.

  The wiping member 20 comprises a wiping lip 50, the free edge 52 of the wiping lip 50 defines a wiping orifice 51, the axis X of the wiping orifice 51 coincides with the longitudinal axis of the neck 15, and advantageously It also coincides with the longitudinal axis of the body 17 of the container 11. Each of the upper portion 30 and the lower portion 40, as shown, specifically contributes to mounting the wiping member in the container neck 15 by a snap fit. There may be slightly protruding beads 33 and 43 on the outer surface.

  The wiping member 20 may be generated by a tubular skirt 48 that surrounds the wiping lip 50.

  For example, the wiping orifice 51 has a free edge 52 that is circular and its diameter can wipe the product present on the stem 13 when the applicator is withdrawn from the container 11. Thus, it matches the diameter of the stem 13.

  According to the present invention, the wiping lip 50 is not made entirely of the same material.

  The wiping lip 50 is deformed as the applicator member 14 passes through, and the applicator member 14 is possibly at least at one point along its length from the axis X, which is larger than the radius of the orifice 51. Has an envelope surface E at a distance.

  The applicator member 14 is, among other possibilities, flocked for mascara brushes, lips or wrinkles having a torsion core and bristles attached or molded in a single piece, eg, of one or more plastic materials End piece, capillary holding end piece, eyeliner chip.

  In the example shown, the wiping lip 50 has sectors 60 and 61 that are staggered circumferentially about the axis X, which are respectively related to the sector 60 by the lower part 40. The sector 61 is generated by the upper part 30.

  In the example problem, these sectors 60 and 61 extend to the lower end 53 of the wiping lip 50. For example, there are four for each of sectors 60 and 61, where, for example, the angular range around each axis X of sector 60 made from a less rigid material is that of sector 61 made from a more rigid material. Bigger than the one. Thus, sector 61 acts as a wiping lip 50 stiffener, changing the number and shape of sectors 61 to the wiping lip 50 without modifying either the diameter of the wiping orifice or the size of the wiping member. It is easily possible to give more or less rigidity.

  In the example of FIGS. 1 to 5, the wiping lip 50 has a generally conical shape that converges towards the bottom of the container.

  The undulations can be generated in sectors 60 and 61 to strengthen the mechanical bond between them. For example, as shown in FIG. 4, it is possible to create a notch 66 at the end of the sector 61, and using this notch 66, the material of the sector 60 Additional anchoring can be created inside.

  It also creates holes in sectors 60 and / or 61 and engages other sector materials within these holes, thereby creating connections that enhance the mechanical binding of the sectors. It is also possible to do so.

  At the same height from the lower end 53 of the wiping lip 50, the sectors 60 and 61 can have the same thickness measured in the radial direction, which can be constant over the entire circumference.

  As a variant, the thickness may vary within a sector or between sectors.

  Two adjacent sectors may not overlap in the radial direction and may be joined, for example, along a radially oriented plane.

  As a variant, two adjacent sectors may at least partially overlap. In examples, a sector made from a stiffer material is on the side of a less stiff material that defines the rest of the sector and covers the stiffer sector on the inside, or on the inside and outside as a whole. Or positioned in the envelope plane.

  The present invention is not limited to a particular number of sectors, for example, with only three sectors 61 arranged at equal angular intervals about the axis X, as shown in FIGS. It is possible to produce the upper part 30 with a single piece.

  The present invention is not limited to the wiping orifice 51 having a circular contour.

  Specifically, the wiping lip 50 can be provided with a variety of shapes that have non-circular, eg, elliptical, polygonal, or other shaped contours. By way of example, FIG. 8 shows a wiping member according to one variant of the invention, in which the sectors 60, 61 each have an undulating free edge. These undulations may allow the sector to move away as it passes through the wiping member, thus favoring the expansion of the wiping orifice.

  The undulation can consist of a series of indentations and / or protrusions formed by sectors along the circumferential direction. The undulation can be a bent part of the ridge that is alternately concave and convex in the circumferential direction. Each swell can extend along a radially oriented axis when the wiping member is viewed from above. All waviness axes can essentially intersect at the center of the wiping orifice.

  In a variant that is not shown, the wiping lip 50 is provided with slots that may or may not be radially oriented, e.g. essentially tangential to the wiping orifice. It can be open.

  FIG. 9 illustrates the possibility that a particular sector, for example the sector 61 generated by the upper part 30, does not extend to the range of the wiping orifice 51. In this case, the sectors 60 generated by the lower portion 40 are joined together to form a single ring 68, the free edge of this ring 68 defining a wiping orifice 51.

  The width of the sector 61 can be reduced in the direction of the wiping orifice 51, as shown in FIG. 9, and the sector 61 is, for example, in the form of a substantially triangular tooth.

  FIG. 9 also shows that the wiping lip 50 can be a dome whose overall shape is concave toward the opening of the container.

  The wiping member can be produced by a single sector of material that is the same or different, eg, different in height, shape, and / or thickness.

  The wiping lip 50 may be completely angularly continuous about the axis X or, as a variant, have edges that can be joined together at rest or not joined at rest Can be interrupted by the slot. Preferably, two sectors made from different materials are in contact with each other.

  Needless to say, the present invention is not limited to the examples just described.

  In particular, further modifications to the wiping member, specifically to the shape of the wiping lip 50, can still be made. The wiping lip 50 can define, for example, in the form of a slot a wiping orifice for wiping an applicator having a flat stem. The wiping member can be a single stage, as shown, or, as a variant, can be multiple stages, one of which can be produced according to the invention and the other stage. Has a wiping lip made entirely from a single material. As a variant, at least two steps are produced according to the invention and the wiping lip has sectors made of materials having different hardnesses over at least part of their height.

  In addition, the wiping member can be referred to as a variable wiping member, which has more wiping lips when stationary so as to vary the amount of product carried by the application member. Or it includes a movable part that deforms to a lesser extent and / or restricts the deformation to a greater or lesser extent when the applicator member passes through it.

  Where relevant, one of the two parts of the wiping member is produced by molding integrally with the rest of the container or part of the container. In particular, the upper part of the wiping member can be composed of the neck of the container and the lower part can be formed by double injection or overmolding or attached to the neck.

  At least a portion of the wiping member can be flocked. For example, flocking all or a portion of the sector produced by one of the upper and lower portions, and then separately bonding the upper and lower portions to adhesive bonding and It can be assembled by welding and / or mechanical attachment.

  At least one of the portions of the wiping member can include a filler designed to create an effect on the product present on the applicator member.

  The wiping member can be made of three or more different materials, in which case the wiping lip can include at least three sectors made from three different materials.

  The expression “comprising” should be understood to be synonymous with “comprising at least one”.
