Abstract
Abstract A pouch usable as a cup comprising a rigid outer sheet and a flexible inner sheet laminated on the inner surface of the outer sheet which are folded to form a pouch. The bottom of the inner sheet is not adhered to the bottom of the outer sheet whereby the outer sheet is deformed by pressing the side edges thereof to expand the bottom of the inner sheet to form a cup.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
217 words
A method of producing a pouch usable as a cup, comprising: providing an opening at the central portion of a flat outer sheet having a reasonable rigidity and flexibility, said opening being interior of the edges of said outer sheet; then bonding the major portion of an inner sheet of greater flexibility than said outer sheet to a major portion of the inner face of said outer sheet, said bonding being not effected only over a minor portion of said inner sheet which consists of a given area around said previously provided opening of said outer sheet; then folding said bonded sheets at the center and on a line extending through said opening so that the folded halves of said bonded sheets are folded toward each other with said inner sheet interior of said outer sheet; and then bonding together the periphery of the folded bonded sheets except at the bottom portion of the resultant pouch to define an unbonded bottom portion in the vicinity of the edges of said outer sheet which define said previously provided opening, such that at said unbonded bottom portion said inner sheet is not bonded to said outer sheet and only the minor portion of said inner sheet not bonded to said outer sheet constitutes the bottom of the resultant pouch.
Claim 2
Independent Claim
217 words
A method of producing a pouch usable as a cup, comprising: providing an opening at the central portion of a flat outer sheet having a reasonable rigidity and flexibility, said opening being interior of the edges of said outer sheet; then bonding the major portion of an inner sheet of greater flexibility than said outer sheet to a major portion of the inner face of said outer sheet, said bonding being not effected only over a minor portion of said inner sheet which consists of a given area around said previously provided opening of said outer sheet; then folding said bonded sheets at the center and on a line extending through said opening so that the folded halves of said bonded sheets are folded toward each other with said inner sheet interior of said outer sheet; and then bonding together the periphery of the folded bonded sheets except at the bottom portion of the resultant pouch to define an unbonded bottom portion in the vicinity of the edges of said outer sheet which define said previously provided opening, such that at said unbonded bottom portion said inner sheet is not bonded to said outer sheet and only the minor portion of said inner sheet not bonded to said outer sheet constitutes the bottom of the resultant pouch.
Claim 3
Dependent Claim
54 words
The method of claim 1 wherein said opening provided at the central portion of said outer sheet is a long, slender slit, and wherein said given area over which said inner sheet is not bonded to said outer sheet is a substantially elliptical area with the slit providing the major axis of the ellipse.
Claim 4
Dependent Claim
38 words
The method of claim 1 wherein said opening provided at the central portion of said outer sheet is a substantially elliptical opening and said inner sheet corresponding to said elliptical opening provides the bottom of the resultant cup.
Claim 5
Dependent Claim
77 words
The method of claim 1 comprising providing elongated slits in said flat outer sheet on opposite sides of said opening and located symmetrically on opposite sides of the line on which said bonded sheets are folded toward each other, said elongated slits being located such that they overlap each other when said bonded sheets are folded, said elongated slits being located at the top of and interiorly of the resulting pouch relative to the bonded periphery thereof.
Claim 6
Dependent Claim
19 words
The method of claim 4 further comprising forming a notch in said bonded sheets adjacent said overlapped elongated slits.
Claim 7
Dependent Claim
26 words
The method of claim 1 wherein said bonding step comprises thermally fusing the peripheral edges of the folded bonded sheets except at said bottom portion thereof.
Claim 8
Dependent Claim
45 words
The method of claim 1 comprising treating the region around said opening at the central portion of said outer sheet so as to prevent said inner sheet from being bonded to said outer sheet over a given area around said opening of said outer sheet.
Claim 9
Dependent Claim
39 words
The method of claim 7 wherein said treating step comprises coating silicone on at least one of said inner sheet and outer sheet to prevent bonding together thereof over said given area around said opening of said outer sheet.
Claim 10
Dependent Claim
14 words
The method of claim 1 wherein said inner sheet comprises a liquid proof sheet.
Claim 11
Dependent Claim
14 words
The method of claim 1 wherein said outer sheet comprises a thick paper sheet.
Claim 12
Dependent Claim
62 words
The method of claim 1 wherein said opening at said central portion of said outer sheet is symmetrically formed relative to the center line thereof so that the bottom edges of the resulting cup, formed by the edges of said outer sheet adjacent the fold line, form an outer circular edge when said pouch is expanded to the form of a cup.
Claim 13
Independent Claim
240 words
A method of producing a plurality of pouches usable as respective cups, comprising: providing a plurality of spaced openings in a flat outer sheet having a reasonable rigidity and flexibility, said openings being interior of the edges of said outer sheet; then bonding the major portion of an inner sheet of greater flexibility than said outer sheet to a major portion of the inner face of said outer sheet, said bonding being not effected only over a minor portion of said inner sheet which consists of given areas around said respective openings of said outer sheet; folding said bonded sheets on a line extending through said openings so that the folded halves of said bonded sheets are folded toward each other with said inner sheet interior of said outer sheet; bonding together the peripheral portions of the folded bonded sheets except at the bottom portions of the resulting pouches to define unbonded portions in the vicinity of the edges of said outer sheet which define said previously provided openings, such that at said unbonded portions said inner sheet is not bonded to said outer sheet and only the minor portions of said inner sheet not bonded to said outer sheet constitute the bottoms of the resultant pouches, portions of said bonded sheets being bonded together between adjacent ones of said spaced openings; and separating said resulting pouches along a line between said adjacent openings to form a plurality of pouches.
Claim 14
Independent Claim
240 words
A method of producing a plurality of pouches usable as respective cups, comprising: providing a plurality of spaced openings in a flat outer sheet having a reasonable rigidity and flexibility, said openings being interior of the edges of said outer sheet; then bonding the major portion of an inner sheet of greater flexibility than said outer sheet to a major portion of the inner face of said outer sheet, said bonding being not effected only over a minor portion of said inner sheet which consists of given areas around said respective openings of said outer sheet; folding said bonded sheets on a line extending through said openings so that the folded halves of said bonded sheets are folded toward each other with said inner sheet interior of said outer sheet; bonding together the peripheral portions of the folded bonded sheets except at the bottom portions of the resulting pouches to define unbonded portions in the vicinity of the edges of said outer sheet which define said previously provided openings, such that at said unbonded portions said inner sheet is not bonded to said outer sheet and only the minor portions of said inner sheet not bonded to said outer sheet constitute the bottoms of the resultant pouches, portions of said bonded sheets being bonded together between adjacent ones of said spaced openings; and separating said resulting pouches along a line between said adjacent openings to form a plurality of pouches.
Claim 15
Dependent Claim
24 words
The method of claim 12 comprising separating said pouches along a line extending through said bonded portions which are located between said adjacent openings.
Claim 16
Dependent Claim
50 words
