Abstract
A closure cap and method of making the same wherein an annular or ring-shaped gasket is injection molded onto the inner surface of a cap shell formed of plastic or metal. The annular or ring-shaped gasket includes at least one radially extending tab integrally formed therewith. A channel in the working surface of a mold core cooperates with the inside surface of the cap to form a mold cavity having the shape of the gasket to be formed therein. The cavity includes a melt inlet and a melt outlet which is in flow communication with a cold well through a connecting portion of reduced cross-sectional area with respect to the cross-sectional areas of both the gasket-defining mold cavity and the cold well.
