Abstract

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.

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.
Claim 2
Dependent Claim
182 words
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.
Claim 3

Claim 5
Dependent Claim
28 words
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.
Claim 6
Dependent Claim
