Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
An easilly accessible container comprising: (a) a sheet of wrapping material having interior and exterior sides, top and bottom ends, and top and bottom portions, respectively, between the ends; the sheet being wrapped around at least one product or product holder such that the top and bottom portion of the sheet overlap one another to form an overlap region comprising an overlapped portion of the sheet and an overlapping portion of the sheet, said top and bottom portions of the sheet being electrostatically bound in the overlap region to define a first bond; (b) a pull tab adhesively affixed in part to the sheet to define a second bond, said pull tab comprising an adhesive-free grasping element; and (c) said second bond being stronger than said first bond whereby a single application of an external pulling force exerted on the grasping element is sufficient to separate said top and bottom portions of the sheet.
Claim 2
Dependent Claim
154 words
An easilly accessible container comprising: (a) a sheet of wrapping material having interior and exterior sides, top and bottom ends, and top and bottom portions, respectively, between the ends; the sheet being wrapped around at least one product or product holder such that the top and bottom portion of the sheet overlap one another to form an overlap region comprising an overlapped portion of the sheet and an overlapping portion of the sheet, said top and bottom portions of the sheet being electrostatically bound in the overlap region to define a first bond; (b) a pull tab adhesively affixed in part to the sheet to define a second bond, said pull tab comprising an adhesive-free grasping element; and (c) said second bond being stronger than said first bond whereby a single application of an external pulling force exerted on the grasping element is sufficient to separate said top and bottom portions of the sheet.
Claim 3
Dependent Claim

Claim 5
Dependent Claim
166 words
An easily accessible container comprising: (a) a wrapping sheet comprised of material selected from the group consisting of polyethylene, polypropylene and polyvinylchloride; wherein the sheet has interior and exterior sides, top and bottom ends, and top and bottom portions respectively between the ends, and wherein the sheet is wrapped around at least one product or product holder such that the top and bottom portions overlap and are electrostatically sealed to one another to define a first bond and form an overlap region comprising an overlapped portion of the sheet and an overlapping portion; (b) a foil pull tab adhesively affixed in part in the overlap region to the external side of the overlapping portion of the sheet to define a second bond, said tab comprises an adhesive-free grasping element; and (c) said second bond being stronger than said first bond whereby a single application of an external pulling force exerted on the grasping element is sufficient to separate said top and bottom portions of the sheet.
Claim 6
