Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
The method of manufacturing an article-enclosing package and carrier handle comprising the steps of arranging the articles in a desired packaging pattern, wrapping a film of shrinking type plastic around said articles, overlapping the longitudinal side edge portions of said film, heat sealing said overlapping side edge portions to form an elongate reinforced section of said package, and forming two longitudinal slits in said package in parallel relationship to the elongate reinforced section and on opposite sides thereof to form a strip integral with said reinforced section and suitable for use as a carrying handle, the longitudinal slits being formed of lesser length than the length of the reinforced section for transferring loads from the carrying handle to the remaining film through a portion of the reinforced section.
Claim 2
Independent Claim
128 words
The method of manufacturing an article-enclosing package and carrier handle comprising the steps of arranging the articles in a desired packaging pattern, wrapping a film of shrinking type plastic around said articles, overlapping the longitudinal side edge portions of said film, heat sealing said overlapping side edge portions to form an elongate reinforced section of said package, and forming two longitudinal slits in said package in parallel relationship to the elongate reinforced section and on opposite sides thereof to form a strip integral with said reinforced section and suitable for use as a carrying handle, the longitudinal slits being formed of lesser length than the length of the reinforced section for transferring loads from the carrying handle to the remaining film through a portion of the reinforced section.
Claim 3
Dependent Claim
43 words
The method as set forth in claim 1 comprising the step of heating the film after the ends are heat sealed and before the slits are formed so as to shrink said film around the packaged articles and to stretch the reinforced section.
Claim 4
Dependent Claim
22 words
The method as set forth in claim 1 wherein the slits are formed by cutting the plastic by means of heated wires.
Claim 5
Dependent Claim
52 words
The method as set forth in claim 1 further including the step of forming an additional layer of plastic at said overlapping side portions, heat sealing said additional layers to said overlapping side edge portions, said two longitudinal slits being on opposite sides of the elongate reinforced section including said additional layers.
Claim 6
Dependent Claim
35 words
The method as set forth in claim 4 wherein the additional layer is formed by the step of folding the overlapping side portions against an adjacent portion of the film to form three film layers.
