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.

1. A two-mode dispensing cap for a container comprising an injection-molded thermoplastic one-piece body, the body having a generally circular end wall, the end wall having a spoon dispensing side and a shake dispensing side, the shake dispensing side including a plurality of relatively small apertures for dispensing therethrough a pourable product carried in the container, the spoon dispensing side including a relatively large aperture of a size sufficient for allowing passage of a spoon therethrough for spooning out product, each of said sides having an associated hinged flap, the flap of the shake side being arranged to selectively close relatively small apertures, the flap of the spoon side being arranged to selectively close said relatively large aperture, the spoon flap having a free edge defining with the line of the associated hinge substantially the full boundary of the spoon flap, the spoon flap including catch means spaced along a line adjacent its free edge, the catch means being arranged to releasably secure the spoon flap in a closed position relative to the spoon aperture and extending along said adjacent line a distance substantially at least as great as one-half of the length of the free edge whereby the Flap is uniformly retained along its free edge.
