摘要

A releasable plastic cap, for sealing containers, comprising: an upper wall that extends over the mouth of a container and covers it, to whose container said stopper is to be applied; an annular sidewall formed integrally with said top wall and hanging from the perimeter thereof; a first annular flange integral with said upper wall and hanging from it, said first flange having an inner and an outer surface and the outer surface forming an angle of approximately 45º with the plane of said upper wall, said first flange being sufficient length and extending sufficiently below the plane of said upper wall, so that its outer surface is coupled to the inner edge of the edge of the wall of a container, the angle of said outer surface of the first flange providing a linear contact with the edge edge; a second annular flange integral with said upper and hanging wall thereof, said second flange being independent, concentric and spaced apart from said first flange, and being concentric and being spaced inwardly relative to said annular side wall at a sufficient distance as for avoiding contact with the latter when said plug has been applied to a container, said second tab further having inner and outer surfaces and being of sufficient length and being extended below the plenum of said upper wall so that the inner surface of said second flange engages the outer edge of the edge of the wall of a container, the inner surface of said second flange providing a linear contact with the edge edge; each of said first and second flanges having a base portion at its intersection with said upper wall, the bases of said first and second flanges being spaced apart at a sufficient distance to ensure contact of the flanges only with the inner edges and outside the edge of the container to which the stopper is applied; said outer surfaces and inner surfaces of said first and second flanges, respectively, being spaced apart from and forming a cavity with respect to the wall of the container when said cap is applied to a container wall, characterized in that said interior surface of said container the second flange forms an angle of approximately 80º with the plane of said upper wall, said flanges having substantially parallel inner and outer surfaces, and said first and second flanges being sufficiently thin to flex and adapt to the variations of the flanges. Inner and outer peripheral edges of the edges of the containers, providing a continuous sealing contact with said edge edges, and wherein said cavity provides an effective seal for containers having a variable wall thickness, nicks and other anomalies, and cooperating in addition said tabs for p to produce a barrier in said cavity that allows the use of the stopper to re-seal said containers.
