Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
A package of sheet material comprising a box-like structure for enclosing a stack of sheet material comprising a base, side walls joined together and interconnecting said base with a cover, said cover having a pair of slots with said slots extending along opposite marginal edges of the cover and a pair of flaps formed between the slots and defined by generally parallel side edges and opposed mating undulated free edges on each flap wherein the undulations on one of said free edges extend past the undulations of the other free edge between which the sheet material may be dispensed and said free edges affording interference with said sheets to hold a sheet between said edges, said marginal edges being spaced the width of a said stack of sheet material.
Claim 2
Dependent Claim
129 words
A package of sheet material comprising a box-like structure for enclosing a stack of sheet material comprising a base, side walls joined together and interconnecting said base with a cover, said cover having a pair of slots with said slots extending along opposite marginal edges of the cover and a pair of flaps formed between the slots and defined by generally parallel side edges and opposed mating undulated free edges on each flap wherein the undulations on one of said free edges extend past the undulations of the other free edge between which the sheet material may be dispensed and said free edges affording interference with said sheets to hold a sheet between said edges, said marginal edges being spaced the width of a said stack of sheet material.
Claim 3
Dependent Claim
19 words
A package according to claim 1 wherein said undulated free edges of the flaps have a sine wave shape.
Claim 4
Dependent Claim
35 words
A package according to claim 2 wherein the undulations of said free edges extend from each flap by 0.1 to 0.5 inch or from a center line across the cover by 0.05 to 0.25 inch.
Claim 5
Dependent Claim
27 words
A package according to claim 1 wherein the undulations of said free edges extend past the free edges of the opposing flap by 0.1 to 0.5 inch.
Claim 6
Dependent Claim
52 words
A package according to claim 1 wherein said structure contains a stack of sheet material with said sheets releasably adhered to each other along opposite edges of successive sheets to permit the free edge of the top sheet to be positioned through and generally parallel to the free edges of said flaps.
Claim 7
Dependent Claim
24 words
A package according to claim 5 wherein means are provided on said side walls for supporting the sheets separated and raised from the stack.
Claim 8
Dependent Claim
18 words
A package according to claim 5 wherein said sheets are adhered by a band of pressure sensitive adhesive.
Claim 9
Dependent Claim
21 words
A package according to claim 7 wherein said band of adhesive is not greater than one-half the width of the sheet.
Claim 10
Dependent Claim
217 words
A package comprising a stack of sheet material comprising sheets of uniform size stacked one on top of another, said sheets being releasably adhered to each other by a band of pressure-sensitive adhesive positioned on each sheet along opposite edges of successive sheets, a box-like structure for enclosing a stack of sheet material comprising a base, side walls joined together and interconnecting said base with a cover, means in said cover for defining a pair of flaps having generally parallel side edges extending generally parallel along opposite marginal edges of said cover and each flap having an opposed mating undulated free edge extending between said side edges wherein the undulations on one of said free edges extend past the undulations of the other free edge between which the sheet material may be dispensed, said side edges having a length to form a slot along said marginal edges of said box-like structure and to permit the flaps to flex and cause said undulated edges to frictionally engage said sheets for holding a sheet between said undulated edges wherein a sheet dispensed between said edges will then be peeled from the next adjacent sheet and said flexible flaps and the free edges thereof will hold successive sheets from being dispensed under the forces applied to peel the sheets apart.
Claim 11
Dependent Claim
217 words
