Description

The present invention relates to the field of cosmetics.

It is known to package certain cosmetic products in containers and to take the product through a sieve having one or more orifices.

The patent application EP 1 086 904 discloses such a device. The applicator comprises a foam applicator member which can be placed during sampling in abutment against the screen wall having the orifices. In one example, the sieve wall has a recess and is slightly set back from the surface of the applicator member at the time of sampling. In this prior application, the body of the container may be made with a deformable part, especially in the form of a bellows, so as to allow the creation inside the container of an overpressure promoting the passage of the product through the orifices for charging the implementing body. Other packaging and application devices have been made with a movable bottom allowing, as and when measuring the product, to compensate for the decrease in the volume of product and allow to exert on it a thrust him allowing to cross the orifices of the sieve. The application EP 1 277 418 A1 discloses an example of such a device. Other known devices comprise a mobile screen in the body of the container and accompanying the wear of the product down into the container.

French patent FR 686213 discloses an example of a device comprising a mobile screen, the applicator being constituted by a tassel that can be pressed against the sieve by the user to withdraw the product.

There is a need to further improve the packaging devices and application comprising a sieve, both to facilitate the loading of the application member product, and to use particularly fragile application organs such as those consisting at least in part of hair or pimples. The invention achieves this objective through a device for packaging and application, comprising: - a container comprising a body, - a sieve movable relative to the body of the container, defining with the latter an interior space of variable volume, containing the product to take, a thrust exerted on the sieve accompanied by a decrease in the internal volume and an outlet of the product by at least one orifice of the sieve. an applicator comprising a support and a flexible application member carried by the support, the support and the sieve being arranged in such a way that the support can come to bear on the sieve to exert said thrust without the applicator member is substantially compressed against the sieve.

Thanks to the invention, the thrust is exerted by the applicator on the screen to cause the volume of the interior space of the container to decrease, forcing the product to pass through the or the orifices of the sieve, without subjecting the organ to application to excessive compression. The applicator member is thus preserved from a deformation which could damage it and it is possible to use within the applicator member very flexible bristles or spikes, which could not otherwise withstand the thrust exerted by the applicator on the sieve without being damaged. The support preferably comes into contact with the screen before the applicator member comes into contact with the screen.

Moreover, the device can remain relatively simple construction, because the sieve can be simply arranged to move axially in the body of the container as the emptying of the product, the body of the container can be made without deformable flexible portion such only a bellows.

Preferably, the sieve is axially movable by sliding in the body of the container and, preferably also, the sieve is arranged to bear against the bottom of the container at the end of its displacement stroke therein.

The sieve may be completely internal to the container. Alternatively, the screen is, for example, mounted as in EP 1 277 418 so as to move relative to a bottom portion of the container which is raised.

Preferably, the applicator member comprises one or more flexible application elements.

By "flexible application element" is meant an application element that deforms when using the applicator to apply the product to human keratin materials. This is for example a hair of a bundle of bristles, including a bundle of bristles made of a synthetic material, attached to the support, or a flexible pin, elastomeric material, for example overmolded on the support or otherwise reported on it. It may still be a foam, a membrane or a hair with a flocking coating.

By "application member substantially not compressed by the sieve", it is necessary to understand a lack of contact between the applicator member and the sieve or, in the presence of a contact, the fact that the force exerted by the sieve on the applicator member when the applicator exerts pressure on the screen to force the product to pass through the orifices of the screen, which is small enough not to damage it, for example between 50 and 500 g of thrust.

Preferably, in case of contact, the compression clearance between the applicator member and the sieve is less than or equal to 2 mm, more preferably 1 mm. Compression play means the distance on which the applicator member is compressed when a thrust is exerted on the applicator to bring it into abutment on the screen.

The screen may have a peripheral wall, preferably converging towards the bottom of the container, and the support being arranged to bear against this peripheral wall.

Such a peripheral wall may contribute to the centering of the applicator relative to the screen when said thrust is exerted. Preferably, the applicator is guided on the container when the user exerts the thrust, in particular to prevent the longitudinal axis of the applicator is oriented obliquely relative to the longitudinal container when the thrust is exerted . Preferably, the angle between the longitudinal axis of the applicator and that of the container when the thrust is exerted is less than or equal to 30 °.

Preferably, the support is rigid. Alternatively, the support is made of a flexible material, but its deformability remains limited when said thrust is exerted, so that the applicator member is preserved.

Preferably, the applicator member is arranged to remain at a non-zero distance from the sieve when the applicator exerts said thrust on the sieve.

Preferably, the support is arranged to bear on the screen by a whole circumference.

Alternatively, the support is arranged to bear against the screen by less than one circumference, which can improve the visibility of the applicator member when used to apply the product and less constrain this one at its base, if any. Thus, the support may have openings in which application elements may engage during the application of the product, by bending in contact with the surface to be treated.

The orifice (s) of the sieve may be positioned in a particular manner with respect to the applicator applicator member so as to improve the loading of the applicator with product, in particular avoiding closing this or these orifices. and / or by promoting the flow of the product between application elements towards the base thereof.

Thus, the application element or elements may be positioned on the applicator so that when it exerts said thrust, the application element or elements are located opposite solid regions of the sieve. The applicator may comprise a plurality of application elements separated from each other at their ends by gaps, and the screen may comprise a plurality of orifices which open opposite said spaces when the applicator is resting on the screen for exert said thrust.

The screen may be made in various ways and in particular comprise at its periphery at least one sealing lip applying to the body of the container.

Preferably, the product is a cosmetic product, especially a makeup product. It may be a make-up product of the skin, lips, eyelashes or eyebrows. The invention also relates to a method of loading the applicator of a device as defined above in product, in which it exerts a thrust on the sieve using the applicator to bring space interior to decrease in volume and force the product out through the orifices, the thrust being transmitted by the support to the sieve without substantial compression of the application member or bodies. The invention will be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended drawing in which: FIG. schematic an example of a packaging device and application according to the invention, - Figure 2 illustrates the loading of the applicator of Figure 1 in product, - Figure 3 is a view similar to Figure 2, a device variant; FIG. 4 illustrates the loading of the application elements into product; FIGS. 5 and 6 are partial views of applicator variants. FIG. 7 is a front view of the applicator of FIG. 5, and FIGS. 8 to 10 are views similar to FIG. 7 of variant embodiments of the applicator.

The packaging and application device 1 according to the invention shown in FIG. 1 comprises a container 10 containing a cosmetic product P and an applicator 20 arranged to allow the user to take the product P contained in the container and the apply on human keratin materials. The product P is for example a liquid, a gel or a powder.

The container 10 comprises a body 11 which is for example made in one piece of thermoplastic material with a bottom 14 and a neck 13. A closure cap 12 can be fixed on the neck 13 to close the container in the absence of 'use.

In the illustrated example, the applicator 20 is not housed inside the container in the absence of use. In an alternative embodiment, the applicator 20 is housed in the container in the absence of use, being for example received in the space 15 of the container under the hood 12.

The container 10 comprises a screen 17 which can move axially along the longitudinal axis X of the container in the body 11 as the emptying of the interior space 18 under the sieve 17, containing the product P. The sieve 17 is for example made in one piece of a thermoplastic material, and comprises at its periphery sealing means which prevent the rise of the product between the periphery of the sieve 17 and the body 11 of the container. In the example considered, the screen 17 thus comprises a sealing lip 30 which is applied at its periphery to the inner surface 31 of the body 11 of the container.

The sieve 17 has a wall 32 through which orifices 33 pass, which allow the product contained in the space 18 to pass through the sieve to be picked up by applicator elements 21 of the applicator, as illustrated in FIG. .

The screen 17 comprises, above the sealing lip 30, a peripheral wall 35 which extends at a short distance from the inner surface 31 of the body 11, or even comes into contact with it.

The wall 35 is in the illustrated example converging towards the bottom 14 of the container, forming an angle with the longitudinal axis X which is for example between 30 and 60 °. The applicator 20 comprises a support 23 which carries the applicator elements 21. When loading the applicator with product, this support 23 can bear against the peripheral wall 35 as illustrated in FIG. exert on the screen 17 a push down by pressing with the applicator 20 on the screen 17, which tends to reduce the volume of the interior space 18 and to force the product to flow through the orifices 33 of the sieve 17.

The support is arranged to bear against the wall 35 early enough to prevent the application elements 21 are pressed against the wall 32 of the sieve 17 during this operation. The support 23 may have for this purpose a chamfer 25 which has substantially the same slope as the wall 35, as shown.

In FIG. 2, it can be seen that the application elements 21 can remain at a non-zero distance from the wall 32 during the support of the support 23 on the screen, thus avoiding being compressed. This figure also illustrates the possibility for the orifices 33 to be placed on the screen 17 so as to face the regions 26 of the applicator member extending between the application elements 21. when the user pushes on the sieve 17 using the applicator 20, the product tends to flow between the application elements 21 and can thus more easily load the application member in depth.

Of course, the invention is not limited to particular application elements.

In the example of Figures 1 and 2, the applicator member is constituted by a set of molded pins, made for example of elastomeric material while the support 23 is made of a more rigid plastic material. The pins 21 are for example overmolded on the support 23 or the applicator is made by bi-injection of material.

In the example of FIG. 3, the applicator member 23 is constituted by a bundle of bristles of greater length than the pins of the example of FIG. 2. Just as in the example of FIG. the openings of the sieve 17 may be arranged relative to the application elements 21 to open between them, as shown in Figure 4, so that the product can easily pass through the sieve 17 without being disturbed at the output by the presence of the elements d application 21.

It can be seen in FIG. 5 that the support 23 can be made with a chamfer 25 which extends over a whole circumference. In a variant, the support 23, as illustrated in FIG. 6, is made in such a way that the support between the latter and the sieve is on less than one circumference and for example, as illustrated, at the end 36 of ribs of the support 23 which extend in this example on only one side of the applicator.

In the example of FIG. 8, the support 23 of the applicator 20 has two diametrically opposed ribs whose distal ends 36 bear against the sieve 17. These ribs define between them openings 41 in which the application elements 21 may expand as they flex during application of the product.

In the example of Figure 9, the ribs are three in number, and in that of Figure 10, the number of four. The application member may also be formed in variants by a membrane, a foam or a coating of flock hairs.

In a variant, the screen is made with another shape and in particular the wall 35 may not be continuous over a whole circumference.
