ABSTRACT:
This invention relates to an end unit of the easy opening type particularly adapted for use in a vacuum packed container. The end panel of the end unit is provided with doming which permits the associated tab to be slightly lifted before a rupturing force is applied with the tab. The particular shape of the dome provides for the necessary doming without an undue stressing of the already scored end panel.
