Horseshoe folded and center unwound plastic bags

Claim 1

A plastic bag dispensing assembly from which large attached plastic bags are tensionally dispensed with minimized twisting, comprising: A. A coreless would roll of said attached plastic bags which are attached but separated by transverse lines of perforations, said roll having an outer diameter, an inner diameter, D i , and an inner circumference, πD i , the length of said bags between said lines of perforations being at least equal to said circumference, whereby said minimizing of untwisting is imparted, said attached plastic bags beginning with an innermost bag and ending with an outermost bag, and said roll being flattened, whereby said inner diameter forms a line having a length calculated as πD i /2, and horseshoe-folded along at least one fold line in parallel to said lines of perforations, whereby said minimizing of untwisting is preserved; and B. a dispensing carton within which said horseshoe-folded roll is stored, said carton having a dispensing opening through which said innermost bag is initially pulled by a user for dispensing thereof.

Claim 10

A method for minimizing the degree of twist in large plastic bags which are to be tensionally dispensed from the central opening of a wound coreless roll of attached plastic bags separated by transverse lines of perforations, said roll having an inner core diameter and an outer core diameter after winding thereof and said plastic bags having a dimension measured in parallel to the inner circumference of said wound roll that is at least as long as said inner circumference, said method comprising the following steps: A. collapsing said wound roll; B. horseshoe folding said collapsed roll along at least one fold line in parallel to said perforations to enable said horseshoe-folded roll to have selected length, width, and height dimensions that can fit into a selected carton having dimensions preferred by a user of said bags; and c. inserting said horseshoe-folded roll into a carton having a dispensing opening in a side thereof.

Claim 11

A method for minimizing the degree of twist in large plastic bags which are to be tensionally dispensed from the central opening of a wound coreless roll of attached plastic bags separated by transverse lines of perforations, said roll having an inner core diameter and an outer core diameter after winding thereof and said plastic bags having a dimension measured in parallel to the inner circumference of said wound roll that is at least as long as said inner circumference, said method comprising the following steps: A. collapsing said wound roll; B. horseshoe folding said collapsed roll along at least one fold line in parallel to said perforations to enable said horseshoe-folded roll to have selected length, width, and height dimensions that can fit into a selected carton having dimensions preferred by a user of said bags; and c. inserting said horseshoe-folded roll into a carton having a dispensing opening in a side thereof.

Claim 21

A method for successively dispensing attached plastic bags from a coreless roll of center-unwindable plastic bags with minimized twist in each dispensed bag, whereby less manual manipulation is required for untwisting the dispensed bags by the user thereof, wherein said roll has an outer diameter, D o , an inner diameter, D i , a wound thickness, T, equalling D o -D i /2, and an inner circumference, πD i , said attached plastic bags being separated by transverse lines of perforations and extending from an innermost bag along said inner circumference to an outermost bag along said outer circumference, and the distance between said perforations being the length of each said bag, said method comprising the following steps: A. forming said roll so that said bag length at least equals said inner circumference; B. collapsing said roll to form a flattened roll having: (1) a pair of ends, (2) an elongated core line which is formed from said inner circumference and has a length, L 2 , calculated as πD i /2, and (3) a selected ratio of roll thickness to roll width, L 1 /L 2 ; and C. selectively folding said flattened roll to form a horseshoe-folded coreless roll which has a nearly square configuration when viewed from an end thereof.

Claim 22

A method for successively dispensing attached plastic bags from a coreless roll of center-unwindable plastic bags with minimized twist in each dispensed bag, whereby less manual manipulation is required for untwisting the dispensed bags by the user thereof, wherein said roll has an outer diameter, D o , an inner diameter, D i , a wound thickness, T, equalling D o -D i /2, and an inner circumference, πD i , said attached plastic bags being separated by transverse lines of perforations and extending from an innermost bag along said inner circumference to an outermost bag along said outer circumference, and the distance between said perforations being the length of each said bag, said method comprising the following steps: A. forming said roll so that said bag length at least equals said inner circumference; B. collapsing said roll to form a flattened roll having: (1) a pair of ends, (2) an elongated core line which is formed from said inner circumference and has a length, L 2 , calculated as πD i /2, and (3) a selected ratio of roll thickness to roll width, L 1 /L 2 ; and C. selectively folding said flattened roll to form a horseshoe-folded coreless roll which has a nearly square configuration when viewed from an end thereof.
