Abstract

A resealable closure for packages is provided which has a package integrity feature. The closure includes a two-ply material having an inner film layer and an outer film layer, forming a top of container. The outer film layer has a sealing panel completely covering a first panel and a second panel of the inner film layer. The sealing panel is permanently attached to the first panel and is releasably affixed a portion of the inner film layer around the perimeter of the first panel to form an opening in the top when the sealing panel with affixed first panel is peeled back from the top. The sealing panel is resealable against the top to seal the opening when the sealing panel is moved back against the top. The package integrity feature comprises the second panel of the inner layer which separates from the sealing panel to indicate that the container has been previously opened.

First claim

The invention claimed is:

1. A package comprising:
a film material with a resealable closure, the film material having at least a first layer and a second layer;
a first cut formed into one layer of the at least two-layer film material forming, at least in part, an opening into the package to provide access to at least one item disposed in the package, the first cut defining at least in part an access panel that is peelable upward to expose the opening;
a second cut formed into the first layer of the at least two-layer film material, the second cut extending transversely from the first cut, the second cut forming, at least in part, an integrity indicating panel displaced from a plane of the first layer upon initial opening; and
a window disposed in the film material permits visible inspection of the integrity indicating panel.

2. The package of claim 1 wherein the first cut is formed into the first film layer and the second layer is disposed over the first layer.

3. The package of claim 2 wherein the window is disposed in the second layer and lies over the integrity panel prior to initial opening.

4. The package of claim 3 wherein the window is at least substantially transparent.

5. The package of claim 1 further comprising an adhesive disposed between at least portions of the first and second layers to provide the resealable closure.

6. The package of claim 1 wherein the integrity indicating panel remains attached to the package subsequent to initial opening.

7. The package of claim 1 further comprising multiple second cuts forming multiple integrity indicating panels.

8. The package of claim 1 further comprising a sealing panel formed, at least in part, by the first cut, the sealing panel having a graspable tab permitting a user to peel back the sealing panel to expose the package opening.

9. A package comprising:
a film material having at least a first film layer adhesively joined to a second film layer;
a tray having the at least two-layer film material wrapped at least partially around the tray to form an outer surface of the package;
a first cut formed into one layer of the at least two-layer film material, the first cut forming, at least in part, an opening into the package to provide access to food items disposed in the package, the first cut defining at least in part an access panel that is peelable upward to expose the opening; and
a plurality of second cuts formed into the one layer of the at least two-layer film material, the second cuts extending transversely from the first cut, the second cuts forming, at least in part, tamper indicators, the tamper indicators configured to be displaced from a plane of the at least two-layer film material upon initial opening to provide a visual indication that the package has been opened, the tamper indicators formed are disposed adjacent the access panel prior to initial package opening such that the tamper indicators and the access panel are contiguous with one another prior to the initial package opening; and
a window disposed in the film material permits visible inspection of the tamper indicators.

10. The package of claim 9 wherein a top of the package includes peripheral graphics disposed outside the opening and the access panel includes graphics thereon and wherein the peripheral graphics and the panel graphics align with one another prior to initial opening of the package.
