Abstract
Pressurized closing device obtained by vacuum mold, of a single sheet of plastic material, for bivalve containers, characterized by being constituted by a female element formed by a depression made inside a hollow conical contour that rises on the plane of a valve connected to said relief by a circular ring thicker than that of the side wall of said depression, and that of the side wall of the relief constituting the support of the female element; also constituted by a male element formed by a hollow cylinder trunk, with a bottom edge strongly chamfered and closed by a circular disc, which rises on a hollow truncated cone base, projecting from the other plane of the leaflet; having on the side face of the male element, about half the height between the head and the base thereof, hemispherical projections or hollows; the female element being arched, towards the outside.
