Resealable closure with package integrity feature

摘要

A resealable package integrity closure includes a film layer forming a top of a container and a flap defining an access opening. A sealing panel completely covers the flap of the film layer. A releasable adhesive is provided on either or both the film layer and the sealing panel for adhering the sealing panel to the film layer. The sealing panel is releasable from the film layer by pulling the sealing panel back in a peeling direction and reclosable against the top to seal the access opening when the sealing panel is moved back against the top. A coating of transferable material is provided on either the sealing panel or on the film layer, which is transferable therebetween to provide a visual indication that the closure has been previously opened.

1. A package comprising:
a wrapper forming a top, sides, and a bottom of the package; a top portion of the package having a multi-layer material with first and second layers; a closure formed by a first cut of the first layer defining a flap and a second cut formed in the second layer defining a sealing panel, wherein a margin of the sealing panel extends beyond the flap, the closure being movable to expose an access opening and a sealing area of the first layer includes the portion of the first layer that faces the margin of the sealing panel; a first portion of the margin facing the first layer or the sealing area having a first adhesive and providing the package with resealing capabilities; a second portion of the margin or the sealing area having a coating of transferable material disposed thereon, the transferable material having a deadening effect on the first adhesive; wherein the transferable material is disposed on the margin or the sealing area such that the transferable material does not interrupt the first adhesive as the first adhesive extends continuously along the access opening; wherein upon initial opening of the package, the coating of transferable material, which has a sufficiently strong bond with the first layer, is transferred from one of the margin or the sealing area to the other thereof and wherein the transferred coating of transferable material is visible beyond the sealing panel when the package is reclosed to provide a visual tamper evident feature.
