Abstract
Abstract A sheet material dispensing container encloses a moisture saturated supply such as a roll of successive sheets of predetermined size connected by transverse perforation or score lines, the leading sheet being withdrawn from the supply through a normally open aperture having free projections at one or more side edges to engage the perforation or score lines and insure separation of each leading sheet during withdrawal.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
A sheet material dispensing package comprising a container enclosing a supply of premoistened liquid absorbent fibrous or equivalent flexible material such as paper in the form of successive sheets of predetermined size separated by weakened regions such as transverse perforations or scores, characterized by a wall of said container having during dispensing sa relatively narrow normally open aperture through which the leading sheet of said supply extends to be manually grapsed for full withdrawal by a consumer, the length of said aperture being materially less than a sheet of said material and the opposite edges of said aperture being spaced apart a distance materially greater than the thickness of said material at least over their major coextensive lengths, and said side edges being formed with laterally aligned relatively stiff sharp edged free projections extending into the aperture and terminating short of pressure engagement with each other but being adapted to operatively engage a weakened region of said supply with a tear force producing coaction during withdrawal of the leading sheet whereby separation of each leading sheet may be positive and reliable.
Claim 2
Dependent Claim
181 words
A sheet material dispensing package comprising a container enclosing a supply of premoistened liquid absorbent fibrous or equivalent flexible material such as paper in the form of successive sheets of predetermined size separated by weakened regions such as transverse perforations or scores, characterized by a wall of said container having during dispensing sa relatively narrow normally open aperture through which the leading sheet of said supply extends to be manually grapsed for full withdrawal by a consumer, the length of said aperture being materially less than a sheet of said material and the opposite edges of said aperture being spaced apart a distance materially greater than the thickness of said material at least over their major coextensive lengths, and said side edges being formed with laterally aligned relatively stiff sharp edged free projections extending into the aperture and terminating short of pressure engagement with each other but being adapted to operatively engage a weakened region of said supply with a tear force producing coaction during withdrawal of the leading sheet whereby separation of each leading sheet may be positive and reliable.
Claim 3
Dependent Claim
165 words
A sheet material dispensing package comprising a container enclosing a supply of premoistened liquid absorbent fibrous or equivalent material such as paper in the form of successive sheets of predetermined size separated by weakened regions such as transverse perforations or scores, a wall of said container having during dispensing an aperture through which the leading sheet of said supply extends to be manually grasped for full withdrawal by a consumer, said aperture having opposite side edges spaced out of pressure contact with each other, and means providing a plurality of free tear starting projections along each side edge of said apertUre projecting in the plane of said wall internally of the aperture sufficiently to operatively engage a weakened region of said supply during withdrawal of the leading sheet whereby separation of each leading sheet is positive and reliable said projections being laterally aligned at opposite sides of said aperture to extend into close substantially point to point association at their inner ends within the aperture.
