Abstract

Safety closure for containers with a circular mouth that is essentially characterized, as regards the container, by the fact that they are situated at the mouth, externally and laterally, a succession of reliefs that, being regularly separated from each other, have their bottom edge a rectangular notch and at least one of its sides forming an inclined plane; and in regard to the cover, by presenting internally inferiorly, next to the edge of its cylindrical lateral wing, a succession of rectangular reliefs that being equal in number and separation from each other, that the lower rectangular notches of the reliefs of the container, they are apt to fit correspondingly and simultaneously in it: concurring in addition the particular circumstance of being fixed at the bottom of the tape a disc of flexible and elastic material, which has a peripheral circular area raised with respect to the bottom of said lid, a purpose to exercise the function of spring on the upper edge of the mouth of the container when both elements are collected, all this so that once the lid is placed, which is done by pressing it against the mouth of the container and making it rotate so that its reliefs internal penetrate into the recesses, of the reliefs of the container, remains the same locked and well. Adjusted by the pressure that the disc-spring exerts, and that to remove the cover, it is necessary to exert an appropriate pressure on it first so that the reliefs descending, they come out of the recesses and can rotate so that the aforementioned reliefs find exit through the spaces that mediate between each two consecutive reliefs of the container.
