ABSTRACT:
A container thermoformed from a relatively thin flat plastic film comprising an upright standing hollow containment formation having an upper flat rim to which a thin cover member is sealingly attached in a sealing pattern. The sealing rim encompassing the containment formation with at least a portion of the sealing rim extending outwardly from the hollow containment formation an amount adequate to permit it to function as a tab. The extending tab portion has a fault line on its underside traversing the tab at a right angle to a centerline extending outwardly from the hollow containment formation which when the tab portion is upwardly bent causes the tab to rupture at the fault line. The rupturing causes the outer tab portion to break away from the remaining tab portion while remaining sealed to the thin cover member which is also upwardly bent to create an outlet passage for flowable material between the remaining tab portion and the thin cover.
