Abstract: The improved strippable seal mechanism inclues first and second polymeric webs each having an exterior and interior surface. The interior surface of at least one of the first and second polymeric webs polymeric webs has a substantially adhesive surface thereon for fixedly but separably adhering to the other polymeric web's interior surface. One of the first and second polymeric webs has at least one line of reduced strength disposed at the exterior surface thereof. A manually grippable tab is disposed adjacent to and operatively connected to the line of reduced strength at the exterior surface of one of the polymeric webs. The manually grippable tab operates in conjunction with the line of reduced strength to direct a peel force along the line of reduced strength to delaminate one of the first and seocnd polymeric webs.

Abstract: The multiple component pressurized package of the present invention in general includes two components:a polymeric inner package component; anda sleeve disposed tightly around the polymeric inner package component.The polymeric inner package component includes at least one sealed compartment for containing therein the package. The compartment is maintained under a pressure which is substantially above that of atmospheric pressure, such as may be useful for example in packaging articles which themselves must be maintained under pressure. The sleeve is positioned in snug circumferential disposition about at least a substantial portion of the inner package component. The sleeve may preferably be made of a polymeric material. Such sleeve compressively contains the inner package component while the inner package component is maintained under pressure. Upon the release of pressure from the polymeric inner package component, the sleeve may then be slideably removed therefrom.
