Case for powdered cosmetic product including an improved opening/closing device

Abstract

A case for powdered cosmetic product includes at least one cover and one base which are movably mounted against one another between at least one closed position and one open position of the case, wherein the base includes a cavity intended to receive the powdered cosmetic product, which is closed by an opening / closing device configured to selectively deliver the powdered cosmetic product, the opening / closing device including at least first opening / closing means which, including first orifices (in communication with the cavity, are secured to the base, and second opening / closing means which, including second orifices, are rotatably mounted with respect to the first means between at least one blocking position and one usage position, wherein the first means include at least one first flexible membrane and the second means include at least one second flexible membrane.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. § 119(a) to French patent application number 1859365, filed on Oct. 9, 2018, the entire teachings of which are incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The invention relates to a case for powdered cosmetic product and more particularly to a case for a powdered cosmetic product that includes an opening / closing device.Description of the Related Art[0003]The invention relates more specifically to a case for powdered cosmetic product, including at least one cover and one base which are mounted for movement with respect to one another between at least one closed position and one open position of the case, wherein the base includes a cavity intended to receive the powdered cosmetic product which is closed by an opening / closing device including at least first means which, including first orifices in communication with the cavity, are secured to the ba...

AI Technical Summary

Benefits of technology

The flexible membranes in this invention are much stiffer and more rigid than traditional membranes made of nylon. The invention also provides a design that allows for easier mounting and maintenance of a pin in a groove.

Problems solved by technology

Such a case in particular has the disadvantage of having a dispersion of the powdered cosmetic product through the multiple orifices of the screen, in other words, an uncontrolled discharging of the product outside of the cavity forming a reservoir.

As in the preceding embodiment example, such a case in particular has the disadvantage of allowing a dispersion of the powdered cosmetic product through the multiple orifices of the screen, on the one hand during the transport of the case (in the closed position) and, on the other hand, during the use of the case (in the open position).

However, the sponge does not totally prevent the dispersion of the powdered cosmetic product outside of the cavity, which poses a hygiene (or cleanliness) problem for the case.

In addition, the sponge also includes on the face thereof in contact with the grid, a quantity of cosmetic product that is often excessive, such that the saturated sponge is thus difficult to use to apply make-up.

However, such a stopper does not maintain the powdered cosmetic product inside the cavity, and does not prevent the product from being emptied at the level of and / or beyond the screen.

Yet, the cosmetic product present on the surface of the stopper is then likely to be dispersed everywhere after the opening of the cover, in particular soiling the case, the hands of the user, etc.

In addition and despite the use of such a stopper, there is always a risk of leakages when the cover (to which the stopper is secured) is not closed correctly, for example not screwed correctly, as the stopper cannot thus perfectly fulfil its role.

Such a design also has the disadvantage of adding, with the stopper, a portion supplementary to the cover, even a part supplementary to the case, which in particular has the consequence of increasing the production cost thereof.

Yet, the stopper does not completely solve the problem of dispersion, as the problem of dispersion or uncontrolled discharging is not limited to the single instance of transporting the case, but also occurs during use, when the case is in the open position.

That is the reason why the screen is generally sized to have a reduced surface, in particular a surface less than the diameter of the case, which furthermore has the consequence of limiting the movement of the user handling an applicator during the use of the case.

Thus, the problem of dispersion is, at best, only partially resolved during the transport by using such a stopper and this problem fully remains during the use of the case.

One of the consequences of this dispersion of the powdered cosmetic product in use, during transport for instance, is ultimately the lack of hygiene (or cleanliness) of the case.

Yet, such a lack of hygiene or cleanliness of the case is particularly badly perceived in terms of quality, i.e. disappointing for a user.

The cases provided with a screen according to the prior art are therefore not satisfactory, in particular due to the abovementioned problems of dispersion of the product and hygiene (or cleanliness).

However, such an opening / closing device makes it, at most, possible to limit the dispersion of the powdered cosmetic product during transport, the problems of dispersion and hygiene (or cleanliness) of the case not being at all particularly resolved during use.

Thus, the movement associated with the delivery of the cosmetic product of such a case during the use thereof causes a significant dispersion of the cosmetic product.

Consequently, the problem of dispersion of the cosmetic product is not particularly resolved during use and hygiene (or cleanliness) of the case is not satisfactory.

In addition, it is not possible to freely choose, accurately, a given quantity of powdered cosmetic product, in particular depending on need, which will not be the same if the user wants to put on make-up completely or only touch up her make-up.

Whether flipped over or even shaken, the same manner of using such a case involves a dispersion of the powdered cosmetic product and, therefore, causes a significant problem of hygiene, and risks of soiling.

Indeed, the dispersion of the cosmetic product occurring during use directly affects the general hygiene of the case, including later during transport and despite the opening / closing device.

Consequently, such a case is not satisfactory, due to problems of dispersion and hygiene, movement and predetermined quantity of product.
