Abstract

The present invention relates to container laminate and container having a container laminate through which materials may be accessed and/or dispensed. The laminate has multiple layers that are peeled away when opened to reveal one or more openings in a layer that remains adhered to the container after opening.

First claim

What is claimed is:

1. A multi-layered peel-away dispensing laminate comprising:
a polymeric layer, wherein the polymeric layer has an upper surface and a lower surface and the lower surface is adapted to be adhered to a container body over an open end of the container;
a pressure sensitive adhesive layer adjacent the entire upper surface of the polymeric layer;
a peelable film layer having an upper surface and a lower surface wherein the lower surface of the peelable film layer is adhered to the upper surface of the polymeric layer by the pressure sensitive adhesive;
a tab disposed in the peelable film layer; and
multiple undercut scoremarks in the polymeric layer, located circumferentially adjacent the tab, and disposed such that the scoremarks will be adjacent the seal position of the laminate on the open end of the container,
wherein the multiple undercut scoremarks comprise parallel lines or concentric lines;
wherein the laminate is undercut through only the polymeric layer in the form of at least one opening; and
wherein the pressure sensitive adhesive layer is pattern applied to the entire peelable film layer other than in the area(s) of the plurality of through holes.

2. The laminate of claim 1 wherein the laminate is free of a pressure sensitive adhesive in the location of the tab.

3. The laminate of claim 1 comprising a plurality of undercut openings in the polymeric layer.

4. The laminate of claim 1 , wherein the laminate is permanently adhered over an open end of a container having at least one sidewall, a closed end, and an open end.

5. The laminate of claim 4 , wherein the container contains granular particles.

6. The laminate of claim 5 , wherein the at least one opening in the polymeric layer comprises a dispensing feature for the granular particles.

7. The laminate of claim 1 additionally comprising a paper layer adhered to the upper surface of the peelable film layer.

8. The laminate of claim 7 wherein the paper layer comprises an ink.

9. The laminate of claim 8 wherein the ink is printed onto the paper layer.

10. The laminate of claim 8 further comprising an overlaquer adhered to the upper surface of the paper layer and over the ink.
