The invention relates to the field of distributors of cosmetic products and typically cosmetic products with a pasty or viscous consistency, for example creams or gels. The invention also relates to cosmetic products that can flow by gravity, such as creams for example.
Many cosmetic products are generally distributed in jars. Classic jars are known that comprise a body forming a cavity designed to contain said cosmetic product with an upper opening that may be closed by sealing means. Generally, the sealing means is a lid or a cap that can be screwed onto said body.
In addition, containers are known that are equipped with a distributing pump that can distribute products of liquid or pasty consistency. Tubes also are known that are used to contain products of liquid or pasty consistency.
Many traditional jars used for cosmetic products require fingers to be used as the means of application, which is not a particularly advantageous method of application and use from a hygiene point of view. Also for hygiene reasons, it is often necessary to limit exposure of the packaged product to air.
Furthermore, it is advantageous to have a product distributor comprising an integrated means of applying said product to the skin, so that said distributor also forms an applicator of said cosmetic product.
Furthermore, the formulations of the cosmetic products can change constantly. Certain cosmetic compositions comprising at least one volatile constituent are being developed. It is important to have a distributor suited to these new formulations.
Moreover, in the case of cosmetic products that can flow by gravity, it can be important to have packaging that allows the rheological properties of said product to be maintained throughout its life. Finally, it can be necessary to renew the packaging of cosmetic products, especially when the products themselves are renewed, in order to draw the attention of the users of said cosmetic products and thus favor their purchase, without forsaking, for obvious financial reasons, the need for distributors that are easy to assemble or which comprise a limited number of separate parts.
In aspects of the invention, an applicator distributor of a pasty (i.e., pasty, thick or viscous) product, includes a body comprising a main reservoir for said product equipped with a main opening, a distribution head for said product, attached to said main reservoir, comprising at least one distribution orifice for said product, and a removable cap cooperating with said body. The pasty product may be a cosmetic or hygiene product that can flow by gravity and which can be designed to be spread, when said product is applied to a part of the human body, typically on the skin, such as on the face.
In aspects of the invention, the distribution head of the applicator distributor can comprise: 1) a peripheral member forming a means of attachment to the main reservoir of the body of the applicator distributor so that the distribution head covers the main opening, 2) a central member comprising a central arch obstructing the main opening and comprising a part forming an application surface for the product, and 3) at least one flexible element that may be deformed under an axial strain, the flexible member cooperating with the central arch by forming a secondary reservoir that can house one dose of the pasty product. The secondary reservoir can be filled when the applicator distributor is pointed facing downwards, the pasty product thereby flowing by gravity from the main reservoir situated above the secondary reservoir by a so-called upstream means of communication. Wwhen axial strain is exerted on the flexible member, the upstream orifice is obstructed, the capacity of said secondary reservoir is reduced, and the capacity changes from a maximum capacity CM to a minimum capacity Cm. Consequently a dose of the pasty product is expulsed towards said application surface by a so-called downstream means of communication.
In aspects of the invention, the applicator distributor of the invention can (1) avoid the fingers as application means, so that it is advantageous from a hygiene point of view, (2) make it possible to limit the contact between the packaged product and the atmospheric air, which is increasingly dust filled, (3) incorporate an application means of the product to the skin, so that the distributor also forms an applicator of said cosmetic product, (4) offer possibilities of adapting to the new cosmetic compositions that comprise at least one volatile constituent, (5) ensure that the rheological properties of said product last for substantially its entire life, by considerably reducing the risks of evaporation, which is important for cosmetic products that flow by gravity, (6) make it possible to renew the packaging of cosmetic products, which is important from a marketing point of view.
Embodiments of the invention allow problems in prior art devices to be overcome. Embodiments of the invention also make it possible to economically form means to obtain predetermined dosed quantities without requiring a dosing pump. Emboidments of the invention also permit the dispensing of N possible doses substantially simultaneously, which may be very advantageous in practice.

The following is a key to reference numbers found in the various embodiments of aspects of the invention disclosed in the figures:
In one embodiment of aspects of the invention, the flexible member (43) can form a resilient flexible strip (43′), so that, in the absence of axial strain (10), the secondary reservoir (44) has a maximum capacity CM which can typically range from 0.01 cm3 to 1 cm3. In an embodiment, the minimum capacity Cm is less than approximately 0.2 CM. In another embodiment, the minimum capacity Cm is less than 0.1 CM.
The flexible strip (43′) may be a transverse strip (43″) located in a plane that is substantially transverse (11) perpendicular to the axial direction (12) of said applicator distributor (1), so as to form a secondary transverse reservoir (44′) whose axial thickness “e” can range from 0.2 mm to 3 mm. When said transverse strip (43″) is moved away from said central member, said secondary reservoir can have its maximum capacity CM.

Regardless of the embodiment of the invention, cap (5′) may comprise an upper wall (50) and a skirt (51) cooperating in a removable manner with body (2) when said applicator distributor (1) is said to be closed, typically via a screw thread or axial clipping, via cooperation means (17) as shown in
As illustrated in
In the invention, said cap (5′), and typically said axial projection (52), may cooperate with said body (2) and typically with said flexible member (43, 43′, 43″), so as to ensure a substantially leak proof seal of said body (2) when said applicator distributor is closed.
In this way, and in this embodiment, any flow of said product out of said secondary reservoir (44, 44′) can be made impossible when said distributor is in the downward-facing position, in order to carry out the automatic filling of said secondary reservoir (44, 44′).
The flexible member (43, 43′, 43″) may be formed in elastomer. However, it is sufficient for said flexible member (43) to have a thickness thin enough to be able to use another plastic material, and for example a polyolefine, so as to have a strip that is both flexible under a relatively low axial strain (10), that can typically range from 0.5.N to 5.N. and that is resilient.
As illustrated in
a to 4c illustrate the case of a distribution head (4) comprising 4 flexible elements.
Advantageously, each of the N flexible elements can correspond to a different maximum capacity CMi, with i ranging from 1 to N, so as to have the choice between N different doses (60) for an application of said product.
As illustrated in these figures, flexible member (43, 43′, 43″) and central member (42) may have in an axial plane containing said axial direction (12), each with an external profile in the same axis as one another, said external profile typically forming a convex surface, as to make said product (6) easier to apply.
In aspects of an embodiment of the invention, cap (5) may be a cap (5′) forming a means of vertical stationing of said applicator distributor (1), wherein said applicator distributor (1) is a so called downward-facing applicator distributor (1′), so that, when said applicator distributor (1′) is closed and resting on any support, said cap (5′) cooperating with said body (2), main opening (30) is then located at the lower part of main reservoir (3) so that product (6) can flow by gravity to said head (4) and up to said secondary reservoir (44). The secondary reservoir (44), in an embodiment, may, in the case of an applicator distributor (1) resting facing upwards on a support, be refilled in one movement by tilting said applicator distributor from an “upward-facing” position to a “downward-facing” position, before each use, whereas said secondary reservoir (44) will be continuously filled with product in the case of a so-called downward-facing applicator distributor (1′).
