Abstract: A composite container body having metal ends secured thereto by means of conventional crimping, and intended for opening by use of any of the various types of toothed driving wheel can openers presently in service. In a particularly preferred embodiment this is accomplished by compressing and densifying the end portion or portions of the composite container body a sufficient distance along its length to eliminate or at least minimize any interference between the toothed driving wheel of the can opener and the exterior of the container body. A weakening score line is preferably provided around the periphery of the metal end to be opened to even further reduce the resistance to cutting encountered by the cutter element as the toothed driving wheel advances said cutter element about the periphery of the container.

Abstract: A hermetically sealed pouch which is pleated, provided with a line of weakness and a tear initiating cut adjacent the line of weakness. The line of weakness extends completely around the pouch near the top of the package. A sealed area surrounds the cut to establish a barrier between the cut and the pouch interior. In one embodiment two parallel lines of weakness are used and the cut is made in the material which intervenes.
