ABSTRACT:
A foolproof sanitary pour type of end cap is provided for a container or can that may be used for providing and dispensing powdered or granular items, such as foods, vitamin and medicine capsules or liquids, such as carbonated soft drinks. The cap body provides an initial completely hermetically sealed cover for the container after the goods have been placed therein for shipment, storage and sale. The sealed relation is such that the inside of the container and its contents cannot be exposed without tearing-off a membrane closure portion across a centrally disposed, inset pouring spout or collar. When the contents are to be first used, a swingable closure lid is opened and the membrane is removed by a pull tab. However, the remaining contents can be then closed-off by the swingable lid which has means for maintaining the contents in a sealed-off relation from the ambient atmosphere and has latching means for flexibly retaining it in closed position until an additional quantity of the contents is to be used.
