Abstract
Abstract In a container for dispensing film, preferably from a supply roll therein, and including a front wall, a bottom wall, a cutter bar along their outer juncture, a tear strip, and die-cut glued areas removably securing the tear strip to the front wall prior to feeding the film lead over the front wall and severing the lead with the cutter bar, at least one separable laminated film retaining attachment arranged between the front wall and tear strip, such attachment including an inner substrate secured to the front wall and having a pressure sensitive adhesive outer surface, and an outer substrate secured to the tear strip and having an adhesive resistant inner surface contacting and froming an interface with such adhesive outer surface, whereby on removal of the tear strip the substrates separate along their interface to expose the pressure sensitive adhesive outer surface for releasably retaining the remaining portion of the severed lead for subsequent feeding and severing operations.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
189 words
A container for dispensing film and including a trailing wall, a leading wall joined to said trailing wall, cutting means arranged along the outer juncture of said leading and trailing walls, a tear strip, and means removably securing said tear strip to the outer side of said leading wall prior to feeding the lead of the film over said outer side of said leading wall and beyond said trailing wall for severing such lead by said cutting means, wherein the improvement comprises: separable laminated film retaining attachment means arranged between said tear strip and said leading wall, and including an inner substrate secured to the outer side of said leading wall and having a pressure sensitive adhesive outer surface, and an outer substrate secured to the inner side of said tear strip and having an adhesive resistant inner surface contacting and forming an interface with said adhesive outer surface, whereby upon removal of said tear strip said inner and outer substrates separate along said interface to expose said pressure sensitive adhesive outer surface for releasably retaining the remaining portion of the severed lead for subsequent feeding and severing operations.
Claim 2
Dependent Claim
189 words
A container for dispensing film and including a trailing wall, a leading wall joined to said trailing wall, cutting means arranged along the outer juncture of said leading and trailing walls, a tear strip, and means removably securing said tear strip to the outer side of said leading wall prior to feeding the lead of the film over said outer side of said leading wall and beyond said trailing wall for severing such lead by said cutting means, wherein the improvement comprises: separable laminated film retaining attachment means arranged between said tear strip and said leading wall, and including an inner substrate secured to the outer side of said leading wall and having a pressure sensitive adhesive outer surface, and an outer substrate secured to the inner side of said tear strip and having an adhesive resistant inner surface contacting and forming an interface with said adhesive outer surface, whereby upon removal of said tear strip said inner and outer substrates separate along said interface to expose said pressure sensitive adhesive outer surface for releasably retaining the remaining portion of the severed lead for subsequent feeding and severing operations.
