Abstract

See full text

An injection-molded thermoplastic closure with shake-and-spoon apertures and associated flaps for selectively closing and opening the apertures. The flaps are releasably retained in their closed positions by catch elements which provide retention forces that are relatively insensitive to dimensional and shape variations in the body resulting from the molding process. In one embodiment, the cap has 'freeze points' and a gate location that reduce the tendency of the cap to assume an oval condition when cooled from molding temperatures. A wide sealing ledge cooperates with a central support for a liner seal positioned in the cap to seal the mouth of a container.
