Abstract

A screw-on flap-style dispensing cap having a snap catch for releasably holding the flap in its closed position. The snap catch and supporting cap body and flap areas are configured to increase the retaining force produced by the snap catch when the cap is locally deformed as the cap is applied to a container mouth with a relatively high torque level so that a tendency of the flap to pop open when over-tightened is compensated.
