Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
A method of providing a stable, unitized pallet load of multitudinous containers such as glass bottles, jars and the like, comprising the steps of: positioning a pallet having a load supporting surface in a container loading location; positioning a base sheet of heat shrinkable plastic material on said pallet, load supporting surface; stacking a substantial plurality of container subassemblies in a suitable array upon said base sheet leaving a peripheral portion of said base sheet exposed; wrapping a heat shrinkable plastic material about the sides of said stacked array; draping a top-sheet of a heat shrinkable plastic material upon the upper surface of said stacked array, and bringing the draped portion of said top sheet and the peripheral portion of said base sheet into contact with said side wrapping sheet; shrinking said material into intimate contact with the exterior surfaces of said stacked array, thereby forming a complete enclosure for the top and sides of the stacked array which exerts an inward restraining action thereupon.
Claim 2
Independent Claim
165 words
A method of providing a stable, unitized pallet load of multitudinous containers such as glass bottles, jars and the like, comprising the steps of: positioning a pallet having a load supporting surface in a container loading location; positioning a base sheet of heat shrinkable plastic material on said pallet, load supporting surface; stacking a substantial plurality of container subassemblies in a suitable array upon said base sheet leaving a peripheral portion of said base sheet exposed; wrapping a heat shrinkable plastic material about the sides of said stacked array; draping a top-sheet of a heat shrinkable plastic material upon the upper surface of said stacked array, and bringing the draped portion of said top sheet and the peripheral portion of said base sheet into contact with said side wrapping sheet; shrinking said material into intimate contact with the exterior surfaces of said stacked array, thereby forming a complete enclosure for the top and sides of the stacked array which exerts an inward restraining action thereupon.
Claim 3
Dependent Claim
24 words
The method of claim 1, wherein said shrinkable material is a heat-shrinkable film comprised of a polymer, or copolymer of compounds having olefinic unsaturation.
Claim 4
Dependent Claim
14 words
The method of claim 2, wherein said heat-shrinkable film is polyvinyl chloride or polypropylene.
Claim 5
Dependent Claim
29 words
The method of claim 3, wherein said step of shrinking said material comprises the step of heating said heat-shrinkable film to a temperature of about 200* to 400* F.
Claim 6
Dependent Claim
41 words
The method set forth in claim 1 including the step of orienting at least each peripheral container subassembly in each layer above the lowermost layer on said pallet such that it is in a different orientation than the subassembly below it.
