Abstract
Abstract Tissue dispensing system for dispensing a stack of interleaved facial tissues from a wall mounted type dispensing cabinet employs a plastic overwrap package of facial tissues having a perforated opening which automatically adheres a front face of the package to a slot in the cabinet to provide inproved tissue dispensing. As each tissue is dispensed, tensile forces are applied to the front face of the package along defined lines by the edges of the tissue passing past the corners of the opening in the package causing the front face of the package to bend into a truncated, hip-roof shaped structure having the truncated end depending from the slot in the cabinet. The tensile forces on the front face cause compressive forces to be applied about a perimeter region situated between the outer extremes of the front face and the outer extremes of a back face of the package in a sense opposing movement of the stack of tissues away from the back face of the package as the stack of tissue diminishes and in a manner preventing collapse of the plastic package during dispensing of the tissues.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
338 words
An improved facial tissue dispensing system for dispensing a stack of interleaved tissues from a wall mounted type dispensing cabinet, said cabinet including a vertically disposed face plate having a dispensing slot wherethrough a series of interleaved tissues from the stack disposed perpendicular with respect to the face plate may be sequentially dispensed, said system comprising: a plastic film overwrap package enclosing the stack of tissues, said package being comprised of (1) a rectangular sheet of plastic material so folded as to overlap for the entire length of said sheet along a central region of a last tissue in the stack forming a band, said band being folded, joined and sealed along the overlap and at both ends of the stack, the seals at the ends of the stack providing side walls about the stack of tissues, the overwrap being disposed to provide an air space region between a front face of the package and a first tissue in the stack; (2) means for forming a narrow dispensing opening disposed lengthwise on the front face of said package said opening being such that the edges of the opening partially curl about the edges of the dispensing slot and mechanically adhere to the slot in a manner resisting movement of said package away from the face plate; the surface of the front face of said package being the type which folds and diverges from said opening to form substantially a truncated hip roof shape extending from said opening as each tissue is dispensed from the stack, the forces of the edges of each tissue on the corners of said opening causing tensile forces to extend across the front face of said package causing compressive forces to be applied between the outer extremes of said front face and the back face of said package opposing movement of the stack of tissues away from the back face as the tissues are dispensed from the cabinet, whereby sequential dispensing of said tissues is improved and collapse of said plastic package is minimized.

Claim 3
Dependent Claim
59 words
Apparatus in accordance with claim 1, wherein the overlapped band seal and the end seals form a I-shaped plastic strut within the material of the backface providing a rigidity to the backface which supports the stack of tissues and which prevents collapse of the backface of said package while said package of tissues is mounted in the dispensing cabinet.
Claim 4
Dependent Claim
18 words
Apparatus in accordance with claim 2, wherein the plastic material is medium density polyethylene about 1.5 mils thick.
Claim 5
Dependent Claim
24 words
Apparatus in accordance with claim 3 wherein said air space region in said package is about 12% of the total height of said package.
Claim 6
Dependent Claim
47 words
Apparatus in accordance with claim 4, wherein said opening is a perforated line having length which is about 60-80% of the length of said package; and wherein the length of perforated line is less than the length of the slot within the faceplate of the dispensing cabinet.
