Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 107 words
In a dispenser apparatus for tearable web-like material, the improvement comprising: an aperture in a wall of the dispenser, said aperture having a plurality of zones wide enough for at least two fingers simultaneously to reach through said zones and into the dispenser to grasp the material and a plurality of slots, the edges of each of said slots converging in a sharp angle at an apex; and the material being a continuous, hollow, cylindrical roll drawable through said zones and toward said apex; whereby individual pieces of said material of a desirable length may be detached from said roll of material when pulled toward said apex.
Claim 2
Dependent Claim 107 words
In a dispenser apparatus for tearable web-like material, the improvement comprising: an aperture in a wall of the dispenser, said aperture having a plurality of zones wide enough for at least two fingers simultaneously to reach through said zones and into the dispenser to grasp the material and a plurality of slots, the edges of each of said slots converging in a sharp angle at an apex; and the material being a continuous, hollow, cylindrical roll drawable through said zones and toward said apex; whereby individual pieces of said material of a desirable length may be detached from said roll of material when pulled toward said apex.
Claim 3
Dependent Claim 21 words
The dispenser of claim 1, wherein said plurality of zones comprises 3 zones and said plurality of slots comprises 8 slots.
Claim 4
Dependent Claim 103 words
In a dispenser apparatus for tearable web-like material, the improvement comprising: an aperture in a wall of the dispenser, said aperture having a single zone wide enough for at least two fingers simultaneously to reach through said zone and into the dispenser to grasp the material and a single slot, the edges of said slot converging in a sharp angle at an apex; and the material being a continuous, hollow, cylindrical roll drawable through said zone and toward said apex; whereby individual pieces of said material of a desirable length may be detached from said roll of material when pulled toward said apex.
Claim 5
Dependent Claim 103 words
In a dispenser apparatus for tearable web-like material, the improvement comprising: an aperture in a wall of the dispenser, said aperture having a single zone wide enough for at least two fingers simultaneously to reach through said zone and into the dispenser to grasp the material and a single slot, the edges of said slot converging in a sharp angle at an apex; and the material being a continuous, hollow, cylindrical roll drawable through said zone and toward said apex; whereby individual pieces of said material of a desirable length may be detached from said roll of material when pulled toward said apex.
Claim 6
Dependent Claim 16 words
The dispenser of claim 3, wherein both of the converging edges of said slot are curved.
Claim 7
Dependent Claim 17 words
The dispenser of claim 3, wherein both of the converging edges of said slot are curved inwardly.
