Claims7
Apparatus for sealing an opening, including:
- an opening defined by at least one edge;
- a seal layer sized and configured to cover said opening, said seal layer having at least one tear line, said seal layer effectively adhered to at least substantially all of the edge of said opening, said tear line positioned and formed for tearing the seal layer along the tearline to permit selective removal of a portion of the seal layer from the opening.
A multi-layered seal, including:
- a first layer of material removably sealed across at least substantially an entire container opening;
- a second layer of material having tear lines formed in it and having protruding tabs, the second layer being operatively affixed in a generally coextensive and abutting relationship with the first layer over at least most of the container opening, the first and second layers operatively bonded to each other, the first layer having no tear lines that correspond to the tear lines of the second layer, the material properties of the first and second layers being such that, pulling on a tab separates the second layer along the relevant tear line and causes the first layer to tear along at least generally the same line despite the first layer not having a tear line formed at that location
