Abstract
Plastic container closures which are preferably injection molded through a centrally placed ingot are disclosed. The closures include a cover panel with a circumferential rim and a pouring opening which corresponds to only a portion of the area of the cover panel. The closure also includes an integral grip and a tearing denotation provided by a reduced thickness groove in the cover panel around the periphery of the portion of the cover panel which is to be removed and in which that groove extends from a point in the proximity of the circumferential rim towards a point displaced from the center of the cover panel at a location beyond the center with respect to the first point, and in which the reduced thickness groove is interrupted to provide a hinge for the portion of the cover panel to be removed subsequent to opening.
