Abstract

A closure for sealing an opened container. The closure includes a pair of rigid members pivotally interconnected at a point on the periphery thereof for movement between at least two operative positions, a closed position with the members forming a generally circular top, each member having a face adjacent to an opposing face of the other member when the members are in the closed position, and an open position with the members rotated apart about the pivot point; a rigid collar member along an outer edge of each pivotally interconnected member, the outer edges generally defining the periphery of the circular top when the pivotally interconnected members are in the closed position; the inner surface of each collar member being adapted to sealingly engage the container when the pivotally interconnected members are in the closed position; and, a latch for securing the pivotally interconnected members in the closed position about the top of the container.
