Abstract
A rectangular stack of interfolded rectangular napkins including a plurality of napkins, each napkin in the stack comprising a first fold in a first direction, and a second fold in a second direction perpendicular to the first direction and bisecting the first fold and the napkin in the second direction, the intersecting first and second folds dividing the napkin into four panels with a pair of adjacent panels located on each side of the second fold, wherein each of the napkins within the stack includes at least one pair of panels arranged in the stack at a level between two pairs of adjacent panels of another of the absorbent napkins within the stack.
Claims17
A rectangular stack of interfolded rectangular napkins comprising a plurality of napkins, said stack having opposing parallel first and third sides and opposing parallel second and fourth sides perpendicular to said first and third sides, each napkin in said stack comprising a first fold in a first direction, and a second fold in a second direction perpendicular to said first direction and bisecting said first fold and said napkin in said second direction, said intersecting first and second folds dividing said napkin into four panels with a pair of adjacent panels located on each side of said second fold,
- wherein each of said napkins within said stack comprises at least one pair of panels arranged in the stack at a level between two pairs of adjacent panels of another of said absorbent napkins within said stack,
- said first fold divides said napkin into a smaller part and a larger part, wherein the area of the smaller part is between ⅕ and ½ of the area of the larger part and wherein said smaller part of said napkin is placed on the outside of the folded napkin, and that said napkins are arranged in said stack with said first folds arranged in an alternating sequence along said first and third opposing parallel sides of said stack such that each napkin is arranged with said first fold opposite said first fold of any adjacent napkin in said stack.
A method of forming a stack of interfolded napkins each said napkin having opposing parallel first and third side edges, and opposing parallel second and fourth side edges perpendicular to said first and third side edges, the method comprising:
- a) providing a plurality of non-folded rectangular napkins;
- b) folding each said napkin along a first axis parallel with said first and third side edges of said napkin to form a first fold, wherein said first fold is made to divide said napkin into a smaller part and a larger part, wherein the area of said smaller part is between ⅕ and ⅓ of the area of said larger part;
- c) folding each said napkin along a second axis parallel with said second and fourth side edges sides of said napkin to form a second fold that is perpendicular to said first fold and bisecting said first fold and said napkin and wherein said second fold is made to place said smaller part of said napkin on the outside of said folded napkin, and wherein said intersecting first and second folds divide said napkin into four panels with a pair of adjacent panels located on each side of said second fold, each pair of adjacent panels comprising a smaller panel formed from said smaller part of said napkin and a larger panel formed from said larger part of said napkin;
- d) forming a rectangular stack of interfolded napkins by placing said napkins with said paired panels of said folded napkins in an overlapping configuration and by inserting a pair of adjacent panels of a following napkin between said pairs of adjacent panels of a preceding napkin within said stack
- e) placing said napkins in said stack with said first folds arranged in an alternating sequence along opposing parallel sides of said rectangular stack with each napkin being arranged with said first fold opposite said first fold of any adjacent napkin in said stack.
