Abstract
A frangible closure for containers consists of a molded plastic closure sealing member and a metal crimping ring. The closure sealing member has a central tear out membrane surrounded by a sealing annulus with an annular weakened tearing zone interposed therebetween. The tear out membrane has a short cylindrical skirt depending from its lower surface and an enlarged ring pull projecting from its upper surface. The metal crimping ring overlies the sealing annulus for tight securement to a container wall opening neck. An upward force applied to the ring pull tears away the center membrane which can be then employed to reclose the opening after partial decanting of the container.
