Abstract
Abstract A dispensing device is disclosed for dispensing nested dished papers. The device has a base for holding a stack of nested dished papers. The dishing of the papers is such that each paper has a bottom wall and a substantially conical side wall. The device includes a paper sticking member mounted on the base adjacent to the stack of nested dished papers. The stack of nested dished papers and the paper sticking member are moved relative to each other so that the conical side wall of the adjacent paper of the stack of nested dished papers is stuck with the paper sticking member. The conical side wall and continued relative movement of the paper sticking member are used for pulling the paper from the stack of nested dished papers and dispensing the same.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
157 words
A dispensing device for dispensing nested dished papers comprising means including a base for holding a stack of nested dished papers, said base having an opening therethrough, the dishing of said papers being such that each paper has a bottom wall and a substantially conical side wall, a paper sticking member movably mounted on said base adjacent said opening, means disposing said stack on said base so that said paper sticking member is positioned within the nearest paper of said stack of nested dished papers, means relatively moving said stack of nested dished papers and said paper sticking member so that the conical side wall of said nearest paper of said stack of nested dished papers through said opening is stuck with said paper sticking member, and means using the conical side wall and continued relative movement of said paper sticking member for pulling said paper from said stack of nested dished papers and dispensing the same.
Claim 2
Dependent Claim
157 words
A dispensing device for dispensing nested dished papers comprising means including a base for holding a stack of nested dished papers, said base having an opening therethrough, the dishing of said papers being such that each paper has a bottom wall and a substantially conical side wall, a paper sticking member movably mounted on said base adjacent said opening, means disposing said stack on said base so that said paper sticking member is positioned within the nearest paper of said stack of nested dished papers, means relatively moving said stack of nested dished papers and said paper sticking member so that the conical side wall of said nearest paper of said stack of nested dished papers through said opening is stuck with said paper sticking member, and means using the conical side wall and continued relative movement of said paper sticking member for pulling said paper from said stack of nested dished papers and dispensing the same.
Claim 3
Independent Claim
157 words
A method of dispensing nested dished papers from a stack by means of a paper sticking member, the dishing of said papers being such that each paper has a bottom wall and a substantially conical side wall, said method comprising: supporting said stack on a base having an opening therethrough, movably mounting said paper sticking member on said base adjacent said opening, disposing said stack on said base so that said paper sticking member is positioned within the nearest paper of said stack of nested dished papers, relatively moving the stack of nested dished papers and the paper sticking member together so that the conical side wall of the nearest paper of the stack of nested dished papers is stuck with said paper sticking member, using the conical side wall and continued relative movement of said paper through said opening sticking member for pulling said paper from the stack of nested dished papers and dispensing the same.
Claim 4
Independent Claim
157 words
A method of dispensing nested dished papers from a stack by means of a paper sticking member, the dishing of said papers being such that each paper has a bottom wall and a substantially conical side wall, said method comprising: supporting said stack on a base having an opening therethrough, movably mounting said paper sticking member on said base adjacent said opening, disposing said stack on said base so that said paper sticking member is positioned within the nearest paper of said stack of nested dished papers, relatively moving the stack of nested dished papers and the paper sticking member together so that the conical side wall of the nearest paper of the stack of nested dished papers is stuck with said paper sticking member, using the conical side wall and continued relative movement of said paper through said opening sticking member for pulling said paper from the stack of nested dished papers and dispensing the same.
Claim 5
Dependent Claim
150 words
A dispensing device for dispensing nested dished papers comprising means including a base for holding a stack of nested dished papers, means holding said stack of nested dished papers in an inverted position on said base, a pinwheel, means rotatably mounting said pinwheel on said base, said pinwheel having a plurality of pins thereon, means disposing said pinwheel inside of the inverted stack of nested dished papers and yieldable means relatively yieldably moving said stack of nested dished papers and said pinwheel toward each other while said pinwheel is rotating so as to stick the innermost paper of said stack with one or more pins on said pinwheel, means providing an arcuate dispensing aperture in said base, and means using the continued rotation of said pinwheel for pulling said innermost paper from said stack so as to dispense the same out of said aperture to the user of said device.
Claim 6
Dependent Claim
150 words
A dispensing device for dispensing nested dished papers comprising means including a base for holding a stack of nested dished papers, means holding said stack of nested dished papers in an inverted position on said base, a pinwheel, means rotatably mounting said pinwheel on said base, said pinwheel having a plurality of pins thereon, means disposing said pinwheel inside of the inverted stack of nested dished papers and yieldable means relatively yieldably moving said stack of nested dished papers and said pinwheel toward each other while said pinwheel is rotating so as to stick the innermost paper of said stack with one or more pins on said pinwheel, means providing an arcuate dispensing aperture in said base, and means using the continued rotation of said pinwheel for pulling said innermost paper from said stack so as to dispense the same out of said aperture to the user of said device.
Claim 7
Dependent Claim
29 words
A dispensing device as claimed in claim 3, a guard for said pinwheel, said guard serving as a guide for said innermost paper in its movement from said stack.
Claim 8
Dependent Claim
30 words
A dispensing device as claimed in claim 3, further including means for controlling the extent to which said innermost paper gets stuck by one or more pins on said pinwheel.
Claim 9
Independent Claim
109 words
A method of dispensing nested dished papers comprising using a rotatable pinwheel having a plurality of pins thereon, utilizing a stack consisting of inverted nested dished papers, disposing said pinwheel inside of the inverted stack, and relatively yieldably moving said stack and said pinwheel toward each other while said pinwheel is rotating so that the innermost paper of said stack is stuck with one or more pins on said pinwheel, providing an arcuate dispensing aperture adjacent said pinwheel, and pulling said innermost paper from said stack by the continued rotation of said pinwheel so as to dispense the same out of said aperture to the user of said device.
Claim 10
Independent Claim
109 words
A method of dispensing nested dished papers comprising using a rotatable pinwheel having a plurality of pins thereon, utilizing a stack consisting of inverted nested dished papers, disposing said pinwheel inside of the inverted stack, and relatively yieldably moving said stack and said pinwheel toward each other while said pinwheel is rotating so that the innermost paper of said stack is stuck with one or more pins on said pinwheel, providing an arcuate dispensing aperture adjacent said pinwheel, and pulling said innermost paper from said stack by the continued rotation of said pinwheel so as to dispense the same out of said aperture to the user of said device.
Claim 11
Dependent Claim
27 words
A method as claimed in claim 6, guarding said pinwheel and guiding said paper in its movement from said stack, said guiding being accomplished by said guarding.
Claim 12
Dependent Claim
27 words
A method as claimed in claim 7, further comprising controlling the extent to which said innermost paper gets stuck by one or more pins on said pinwheel.
