Abstract
Abstract A method of making a beverage packaging bag made of at least one laminar panel which has an inner layer and an outer layer with appropriate portions of the laminar panel bonded and thus sealed together by heating and a plurality of cuts provided in the outer layer to facilitate piercing of a straw through the panel, by directing a laser beam through a mask at the bag.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
162 words
A method of making a beverage packaging bag comprising at least one laminar thermo-adhesive panel having an inner layer, wherein at least a portion thereof is made of aluminum, and an outer layer, appropriate portions of said laminar panel being bonded and sealed by heating, wherein said outer layer of said laminar thermo-adhesive panel is provided with a plurality of cuts in a predetermined pattern and to a predetermined depth and width, said method, comprising the steps of: (a) forming said cuts by providing a laser emitting a beam; (b) directing said beam toward said bag; (c) interposing a mask having said predetermined pattern therein in said beam; (d) focusing said beam onto said outer layer; (e) regulating said mask such that said beam penetrates said outer layer only to said predetermined width; and thereafter (f) regulating said laser such that said beam penetrates said laminar panel completely through said outer layer and up to said aluminum portion of said inner layer.
Claim 2
Independent Claim
162 words
A method of making a beverage packaging bag comprising at least one laminar thermo-adhesive panel having an inner layer, wherein at least a portion thereof is made of aluminum, and an outer layer, appropriate portions of said laminar panel being bonded and sealed by heating, wherein said outer layer of said laminar thermo-adhesive panel is provided with a plurality of cuts in a predetermined pattern and to a predetermined depth and width, said method, comprising the steps of: (a) forming said cuts by providing a laser emitting a beam; (b) directing said beam toward said bag; (c) interposing a mask having said predetermined pattern therein in said beam; (d) focusing said beam onto said outer layer; (e) regulating said mask such that said beam penetrates said outer layer only to said predetermined width; and thereafter (f) regulating said laser such that said beam penetrates said laminar panel completely through said outer layer and up to said aluminum portion of said inner layer.
Claim 3
Dependent Claim
25 words
A method according to claim 1, further comprising the step of moving a plurality of said bags on a conveyor and directing said beam thereto.
Claim 4
Dependent Claim
16 words

A method according to claim 5, wherein said predetermined pattern is in the form of a plurality of non-intersecting radial lines.
Claim 8
Dependent Claim
20 words
A method according to claim 5, wherein said predetermined pattern is in the form of a plurality of parallel lines.
Claim 9
Dependent Claim
16 words
A method according to claim 7, wherein said predetermined pattern is intersected by a single line.
Claim 10
Dependent Claim
17 words
A method according to claim 5, wherein said predetermined pattern is in the form of an X.
