ABSTRACT:
A self-sealing, tamper-evident closure including a cap body and an integrally-formed gasket valve is provided for use on a container. The cap body includes a tab integrally molded onto a removable frangible portion which breaks away from the cap body and exposes a self-sealing, flexible gasket valve. The gasket valve is molded in place on an inner surface of the cap body and includes a longitudinal slit to provide a dispensing orifice. A method for making a closure of the present invention is also disclosed, wherein an integral cap body is formed by injection molding, a quantity of liquid gasket material is deposited within a pocket formed on the cap body, a flexible gasket valve is formed by the liquid gasket valve material curing in place within the pocket and a longitudinal slit is imposed through the gasket valve to provide a dispensing orifice.
