摘要

Improvements in the construction of sealing and sealing devices for containers for liquids, characterized in that a corking cap screwed externally to said container is attached to the mouth of a container, and a spongy applicative body of the packaged liquid is provided in its upper part. underneath this body, a sealing gasket separating the interior of the container, the latter having, inside its mouthpiece, a spike mounted on a fixed support, centered with the axis of the container and normal to said cover, all so that in the period prior to the first use of the liquid the capsule is in the position of maximum unscrewing such that the operculum is out of reach of the tine, so that it remains intact, while in the first use is caused the screwing of the capsule to cause the perforation of the operculum by said quill determining the exit of the liquid and the consequent imp spongy body, the successive seals being made by means of the barb itself that intercepts the hole caused in the operculum by keeping the capsule screwed, offering the particularity that the sealing of the peripheral threaded area is obtained in all circumstances by means of the frictional sliding contact of a rigid wing derived from a circular flange attached to the capsule inside the mouth of the container, against the inner wall of the latter, for all whose effects cited the capsule is subject to two extreme positions that limit its stroke, the first of which is constituted by the coincidence butt between the aforementioned fin and a projection that presents internally the upper edge of the embouchure, and the other by the coincidence between the same projection and a plane existing at the bottom of the capsule, existing the height relationships that establish the operation of the device.
