ABSTRACT:
The disclosure describes the combination of a plastic container and of a plastic lid which are adapted to be hermetically sealed to one another. The lid defines a tab that projects outwardly and includes a tangentially extending indentation that separates the tab into an inner portion and an outer portion. The indentation forms a hinge so that upward forces exerted accidentally on the tab causes only the outer portion of the tab to pivot about the indentation thereby preventing the inner tab portion from lifting and detaching the hermetically sealed lid portion from the container. The hinge also serves to enable the tab to be placed in a downwards pivoted position where it is fixedly attached to the container side wall prior to being used.
