DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to an applicator assembly for a liquid or pasty product, such as a cosmetic product. It relates more particularly, but not exclusively, to eyeliner or mascara products.
BACKGROUND OF THE INVENTION
An applicator assembly of this kind is known, inter alia, from French Patent Specification No. 2 603 780, which describes a bottle comprising a neck, the opening of which narrows towards the bottom of the bottle to end in a passage into which the end of an applicator brush penetrates in order to be impregnated with the cosmetic product. In the case of an eyeliner tip, i.e. a very fine tip, the passage has a very small diameter in which sufficient capillary action is produced that the bottle does not leak, even if it is turned upside down. In the case of a mascara product, the applicator necessarily has a larger diameter, so that the diameter of the passage is at least of the order of 2 to 3.5 mm. In this case, the bottle leaks if it is turned upside down as there is no longer any capillary action.
SUMMARY OF THE INVENTION
The aim of this invention is to obviate this disadvantage.
In order to solve this problem, it is proposed according to the invention to dispose the applicator element in a case which prevents the passage of the product towards the exterior. However, capillary orifices are formed in the case in order to maintain impregnation of the applicator element by capillary action. U.S. Pat. No. 3,951,157 had already proposed, in a similar assembly, mounting an applicator element in a case provided with slots, but these non-capillary slots cooperated with a pulverulent product and would not have been able to prevent the flow of a liquid product.
FR-A-1 517 002 relates to a nail varnish bottle comprising a tubular container receiving the applicator, this tubular container communicating with the interior of the bottle by means of a filling hole which is not a capillary orifice.
FR-A-1 076 477 relates to a deformable seal intended more particularly for products based on very volatile solvents, e.g. nail varnishes, and does not include a capillary orifice.
This invention therefore relates to an applicator assembly for a liquid or pasty product, such as a cosmetic product, comprising a bottle which defines a container for the product and which is provided with a neck and a movable cap capable of closing the neck of the bottle, the cap being provided in its interior with a stem to the end of which an applicator element is fixed in such a manner that, in the closed position of the cap, the applicator element penetrates into the bottle and is impregnated with the product, a shoulder being provided on the cap and being adapted, in the closed position of the cap, to bear against a seat integral with the bottle, the said bottle including a case, the inner recess of which is adapted to the external shape of the applicator element, the said case being disposed in such a manner that, in the closed position of the cap, the applicator element is housed therein, characterised in that the shoulder is an annular shoulder formed on the stem, the said seat having a corresponding shape and comprising a central orifice for the passage of the said applicator element from one side of the seat to the other, the said seat being connected to the said case, the said case comprising in its wall at least one capillary opening allowing the product to impregnate the applicator element, but preventing the flow of the product from the container in which it is situated towards the exterior.
The mounting of the applicator element therefore no longer results in leakage of the product, as was the case in French Patent Specification No. 2 603 780, as the product must pass into the capillary openings in the case. The applicator element is no longer immersed directly in the product contained in the bottle, this moreover preventing contamination of the container by the applicator element, but instead it becomes impregnated with the product in a sort of mini auxiliary container formed by the case,
