ABSTRACT:
A novel self-sealing container closure that prevents spillage and that simultaneously permits drinking from a container or cup, all without the removal of the closure. The novel closure comprising a generally resilient central face having an aperture therethrough defined by overlapping edges, and a skirt extending from the periphery of the central face, said skirt having an integral engaging means formed as the inner face of the skirt for seating engagement with a rim portion of a container, said means including a skirt bead, said bead being formed into two connecting sections, one section being disposed in one plane and the other section being disposed in a second plane, said planes intersecting at an acute angle. The function of said two connecting sections in combination with the other recited features herein is to present a constant tensioning action for suitable sealing engagement of the edges of the aperture when loaded or affixed to the rim of the container or cup.
