ABSTRACT:
Improved sectionalized depressible opener tab for easy open containers wherein one of the sections can be relatively small as compared to the dimensions of the overall tab while being connected by an improved hinge arrangement to the remainder of the tab. This hinge arrangement permits either a simultaneous selective depression of multiple tab sections or depression of only one tab section to obtain initial separation of the tab from the container component with which the tab is associated and a controlled release of internal container pressure.
