Method for sealing blister packages for easy opening

Claim 1

A method for packaging items in a blister-type two-part package providing a product enclosure, said two parts including mating, matching, peripherally contiguous, multiple-cornered, straight edge portions extending outwardly from said enclosure, comprising superposing the two parts with an item to be packaged therebetween and aligning said straight edge portions in unsealed relationship whereby a hairline opening is provided between the edge portions, bonding said edge portions together around the entire periphery of the package with an adhesive-coated tearable tape over around and under the edge portions in a continuous manner whereby a skip-seal is provided between the superposed edge portions, cutting off at least one of the corners of said taped edge portions to provide an easy-starting tear point for severing said tape and separating said edge portions and said parts, said tape-sealed edge portions acting as positive predictable guidelines along which said tape will shear when said two parts are pulled apart.

Claim 2

A method for packaging items in a blister-type two-part package providing a product enclosure, said two parts including mating, matching, peripherally contiguous, multiple-cornered, straight edge portions extending outwardly from said enclosure, comprising superposing the two parts with an item to be packaged therebetween and aligning said straight edge portions in unsealed relationship whereby a hairline opening is provided between the edge portions, bonding said edge portions together around the entire periphery of the package with an adhesive-coated tearable tape over around and under the edge portions in a continuous manner whereby a skip-seal is provided between the superposed edge portions, cutting off at least one of the corners of said taped edge portions to provide an easy-starting tear point for severing said tape and separating said edge portions and said parts, said tape-sealed edge portions acting as positive predictable guidelines along which said tape will shear when said two parts are pulled apart.

Claim 3

A method of packaging and unpackaging an item packaged in a preformed blister-type package wherein said package is constructed from two pieces forming an enclosure area for said item and has straight-sided, polyangular edge portions extending outwardly from said enclosure area of both pieces comprising superposing the two pieces with said item therebetween so that the edge portions thereof face each other in a mating, matching, peripherally-contiguous, but unsealed relationship, whereby a hair line opening is provided between the edge portions and bonding said edge portions together around the entire periphery of the package with an adhesive-coated tearable tape, said tape continuously covering said edge portions over, around and under thereof in a skip-sealed relationship, cutting through said taped skip-sealed edge portions at their original corners to change their relationship from one that is sealed together to one that is simply bonded together and thus providing cuts in the formerly taped corners for easy-starting tear-points at which to tear said tape apart, and then pulling said edge porTions and said pieces apart beginning at one of the cuts and along the two-way directioned line of tear along said skip-seals of said bonded edge portions.

Claim 4

A method of packaging and unpackaging an item packaged in a preformed blister-type package wherein said package is constructed from two pieces forming an enclosure area for said item and has straight-sided, polyangular edge portions extending outwardly from said enclosure area of both pieces comprising superposing the two pieces with said item therebetween so that the edge portions thereof face each other in a mating, matching, peripherally-contiguous, but unsealed relationship, whereby a hair line opening is provided between the edge portions and bonding said edge portions together around the entire periphery of the package with an adhesive-coated tearable tape, said tape continuously covering said edge portions over, around and under thereof in a skip-sealed relationship, cutting through said taped skip-sealed edge portions at their original corners to change their relationship from one that is sealed together to one that is simply bonded together and thus providing cuts in the formerly taped corners for easy-starting tear-points at which to tear said tape apart, and then pulling said edge porTions and said pieces apart beginning at one of the cuts and along the two-way directioned line of tear along said skip-seals of said bonded edge portions.
