Abstract

A tamperproof package having a plastic carrier heat-sealed to a laminate except for a transverse zone is disclosed. A tear-off strip beginning at the transverse zone must be torn off before the laminate may be separated from the carrier layer to prevent access to a product in a pocket on the carrier.

Claims

1. A package comprising a. a carrier layer having a generally rectangular shape, said layer having a pocket, said pocket being open on one side of said layer, said pocket containing a product;

b. a laminate having a surface sealed to said one side of said layer and covering said pocket, said seal being between said layer and laminate surface except for an unsealed zone which extends between two edges of said layer from edge to edge, said zone containing a hole only in said carrier layer, c. said layer and laminate having a tear-off strip, at least a part of said hole being between said pocket and said strip, d. means weakening said layer and said laminate in a direction which is generally parallel to said zone and intersects or is tangent to said hole for initiating tearing said laminate and layer in said direction along said zone, e. and said laminate including a tough polymeric reinforcing plastic layer between and bonded to a layer of paper and a layer of metal foil, said laminate surface being on said metal foil layer.

2. A package in accordance with claim 1 wherein said weakening means includes a cut in said carrier layer at two locations contiguous with the hole, said cuts being aligned with one another and generally parallel to said zone.

3. A package in accordance with claim 1 wherein said carrier layer is a polymeric plastic layer having a thickness of about 0.007-0.02 inches thick, said carrier layer being a transparent polymeric plastic, and said product being a pharmaceutical product.

4. A package in accordance with claim 1 wherein said zone extends across two adjacent edges of said carrier layer so that said strip is generally triangular in shape.

5. A package in accordance with claim 1 including a. a plurality of packages having their carrier layers and laminates jointed side-by-side and delineated by rows of generally parallel perforations, said zone on one carrier layer being aligned with the corresponding zone on the next adjacent carrier layer, b. means to prevent simultaneous tearing of more than one tear-off strip, said means including a cut extending transversely across one of said rows of perforations which delineates the last package of a strip with respect to the remainder of the strip, and the side edge of said last package of the strip which is opposite said one row of perforations being free from any cut or perforation, whereby it is necessary to separate said last package from the strip along said one row of perforations before initiating tearing of the tear-off strip thereon.
