摘要：A hinged dispensing closure of unitary molded construction is disclosed whichmay be readily opened by an adult using one hand. A narrow slot of short length ismolded near the periphery of the top wall of the snap-hinged cover cap opposite itshinged connection to the main closure. The sidewall of the cover cap includes axiallyextending parallel score lines from near its skirt edge to the ends of the slot to define atab. Pressing by the thumb on the tab while holding the package in the same handruptures the scores and deflects the tab inwardly for ready access to an exposed edge ofthe formed slot; and pressure on the edge opens the cover cap. The deflected tab is heldby an internal cam wall inwardly of the slot, which indicates that the package is openedwhen the tab is held in this deflected position. A second embodiment provides a hookand latch locking means between the main closure and cover cap opposite the hinge. Thislock may be disengaged by the thumb for unlatching the cover cap by depressing its skirtwall at the hook and latch location and opening the cover cap with one hand. The mainclosure is threaded on the container. The main closure and container are provided withcooperating ratchet teeth to render the closure on the container a safety closure againstaccidental removal by children.
