ABSTRACT:
A sealed container with lip and bonded covering, having a circular top, is disclosed. A tab is provided for, within the limitations of a circular top, which allows the seal to be easily opened by hand. For example, the circular cut may be positioned so as to extend to one side of the container more than it does on the opposite side so that the tab is created from a portion of the covering on the extending side.
