ABSTRACT:
A container cap and a method for forming a container cap with a skirt portion that attaches to the container are provided. The cap has depending tabs attached by a living hinge to the skirt portion. Threads are provided as connectors for mating engagement with the container. The hinged tabs are folded through at least 180.degree. to be received in cavities in the skirt portion. The cavities have converging sidewalls mating with converging edges to snap lock the tabs in the operative position. A lug may be provided on the threads to lock the cap on the container. The method includes the steps of forming the cap with hinged depending tabs, removing the core mold from the cap interior, flexing the tabs inwardly to allow the cap to drop out of the cavity mold, folding the tabs into the skirt portion and snap locking the tabs into the cavities.
