Patent ID: 8616372

Claim:
A tamper-resistant, multi-piece package comprising: a planar, fibrous substrate comprising: an unprinted side; a printed side opposite the unprinted side; a centerline configured to facilitate folding, dividing the fibrous substrate into a first region and a second region; and a first opening passing through the second region; a dry-tack coadhesive layer having first and second opposing portions located on opposing unprinted sides of both the first and second regions, respectively, wherein the dry-tack coadhesive is an aqueous material that is configured to dry as a coadhesive after application to the substrate; and a blister layer configured to accept a product, wherein the blister layer includes a peripheral section; wherein the first and second opposing portions of the dry-tack coadhesive layer are brought together by folding the substrate along the centerline sealing the opposing portions of the dry-tack coadhesive layer to each other; wherein the peripheral section of the blister layer is captured between the opposing portions of the dry-tack coadhesive layer without the dry-tack coadhesive adhering to the blister layer.
