Abstract
A package for foodstuffs including a cup and a lid. The cup includes an opening surrounded by a flange. The flange has a sealing surface adjacent the opening and a beveled surface spaced outwardly of the sealing surface. The beveled surface extends along a periphery of the flange. The sealing surface has an inner radius R.sub.1 and an outer radius R.sub.2, the outer radius R.sub.2 defining the juncture between the sealing surface and the beveled surface. The beveled surface extends at a predetermined angle with respect to the sealing surface. The lid includes a tab extending outward of the periphery of the flange. The lid is affixed to the sealing surface thereby sealing the opening of the cup. The lid is not affixed to a substantial portion of the beveled surface. The lid and the sealing surface are adapted to release upon exertion of a predetermined pulling force on the tab.
