Claim 18

In a pop-up dispensing system for dispensing folded sheets, said dispensing system including a plurality of separate sheets and a dispensing aperture, each of said sheets having two opposing side regions and two opposing end regions joining said opposing side regions, said sheets having a longitudinal direction which extends between said opposing side regions and a transverse direction which is perpendicular to said longitudinal direction, and said opposing end regions each including an end edge which extends across said sheets between said opposing side regions and defines a maximum longitudinal length of said sheets, the improvement comprising: (a) said sheets being associated with one another to form a continuous web such that the end regions of each sheet overlie end regions of adjoining sheets in a co-extensive relationship so as to form at least one pair of adjacent sheets having at least one overlapping region bounded at least partially by an opposing end edge of each sheet of said at least one pair of adjacent sheets; and (b) said opposing end edges being at least partially non-parallel with one another, and said at least one overlapping region having at least one point of greatest overlap and at least one point of least overlap measured in said longitudinal direction, said at least one point of greatest overlap being greater than said at least one point of least overlap; whereby when a sheet adjacent to said dispensing aperture is withdrawn through said dispensing aperture, the end portion of said sheet exerts a pulling force on the end portion of a subsequent adjacent sheet via said overlapping region to partially withdraw said interleaved end portion of said subsequent adjacent sheet through said dispensing aperture, and whereby complete separation of said overlapping region occurs generally outside of said dispensing aperture to free said sheet for use and form a free end portion of said subsequent sheet, and whereby said free end portion of said subsequent adjacent sheet is retained outside said dispensing aperture for grasping.

Claim 19

In a pop-up dispensing system for dispensing folded sheets, said dispensing system including a plurality of separate sheets and a dispensing aperture, each of said sheets having two opposing side regions and two opposing end regions joining said opposing side regions, said sheets having a longitudinal direction which extends between said opposing, side regions and a transverse direction which is perpendicular to said longitudinal direction, and said opposing end regions each including an end edge which extends across said sheets between said opposing side regions and defines a maximum longitudinal length of said sheets, each of said sheets further having at least one fold line extending generally transversely across said sheets from one side region to the other side region, said at least one fold line being disposed intermediate said opposing end regions, the improvement comprising: (a) each of said sheets being folded along said at least one fold line and said sheets being superposed on one another with end portions of adjacent sheets being interleaved with one another such that an end portion of one sheet separates end portions of an adjacent sheet from one another; (b) said sheets being associated with one another to form a continuous web such that the end regions of each sheet overlie end regions of adjoining sheets in a co-extensive relationship so as to form at least one pair of adjacent sheets having at least one overlapping region bounded at least partially by an opposing end edge of each sheet of said at least one pair of adjacent sheets; and (c) said opposing end edges being at least partially non-parallel with one another, and said at least one overlapping region having at least one point of greatest overlap and at least one point of least overlap measured in said longitudinal direction, said at least one point of greatest overlap being greater than said at least one point of least overlap; whereby when a sheet adjacent to said dispensing aperture is withdrawn through said dispensing aperture, the end portion of said sheet exerts a pulling force on the end portion of a subsequent adjacent sheet via said overlapping region to partially withdraw said interleaved end portion of said subsequent adjacent sheet through said dispensing aperture, and whereby complete separation of said overlapping region occurs generally outside of said dispensing aperture to free said sheet for use and form a free end portion of said subsequent sheet, and whereby said free end portion of said subsequent adjacent sheet is retained outside said dispensing aperture for grasping.

Claim 20
