Abstract

A valve plug for the application of a liquid product to a surface, constituted by a cylindrical piece of elastic material provided with an axial bore or tube and intended to fit tightly in the mouth of the container containing the liquid, in the upper surface of which the sponge pad of impregnation is applied and held, which is additionally retained by means of an annular part having an upper radial flange which is applied tightly to the lower part of the sponge and which has two internal annular ribs in which it is applied by elastic jump an upper edge of the neck of the container, the assembly being closed by an external cylindrical cap that is threadedly applied to the neck of the container, characterized in that two flanges or fins protrude from the outer end of the outlet conduit of the cap. Valves that are coupled in normal position by their edges to constitute a closure that ev the outlet of the liquid is introduced, said tabs being inserted into a central duct formed in the applicator sponge attached to the exterior face of the stopper and in such a way that the upper end of the valve thus formed is below the outer surface of the sponge. Of application, such being the provision that when applying said sponge to a surface to be treated, the crushing thereof causes the end of the valve constituted by the two fins or tabs to contact said surface to separate them intermittently in the rubbing movement carried out with the sponge, whereby the liquid exits through the slit formed between said fins, extending through the same mass of the sponge, with which a uniform distribution of the product of the container on said surface is achieved.
