Abstract
A multipli-layered tamper-proof wrap consisting of a number of over-layed thin plastic sheets bonded around the outer edge to contain one or a number of chemical layers therein, appropriately separated, whose penetration or puncture will result in a visual indication at the puncture, and including distinct seals fixed at spaced intervals to the outer or external wrap sheet that indicate wrap or product origin and are to discourage wrap substitution. The wrap is for encapsulating a consumer product so as to provide a continuous wrap surface therearound that will give a visual indication of a breach in wrap integrity at a point of penetration or puncture.
Claims27
A tamper-proof wrap for encasing a consumer product for shelf display comprising, interior and exterior sheets of a thin plastic material positoned over one another and bonded together around the outer edge and including a layer of a select chemical sealed therebetween such that on puncture of a wrap exterior sheet, a chemical response will occur that will produce a visual indication at the wrap puncture;
- and distinctive seal means fixed at spaced intervals over said wrap exterior sheet.
A tamper-proof wrap for encasing a consumer product for shelf display comprising, inner and exterior sheets of a thin plastic material positioned over one another and at least one separator sheet of a thin plastic material sandwiched theretween separating different layers of compounds from one another, the sheets bonded together around the outer edge, and the compounds selected to provide a reaction on their mixing at a puncture of the separator sheet to provide a visual indication at that puncture;
- and distinctive seal means fixed at spaced intervals over said wrap exterior sheet.
A method for encasing a consumer product for shelf display in a tamper-proof wrap that will provide a visual indication of a puncture comprising the steps of positioning a consumer product on a section of the wrap large enough to completely encase the product;
- wrapping the product with that wrap such that the wrap edge meet and overlay one another;
- rolling the wrap edges together;
- and bonding the rolled wrap edges to a section of the wrap surface that will provide a visual indication of a puncture.
