Abstract
Abstract A taping paper for sealing a gap formed by a piece of sheetrock and an object piercing the sheetrock wherein a substantially flat substrate having a central axis and an outer peripheral surface is provided with, in the preferred embodiment, a plurality of continuous tear lines spaced apart from each other at different radial distances from the central axis. A method for sealing the gap is provided wherein the substrate is torn along a tear line which is approximately the same size and shape of the outer peripheral surface of the object piercing the sheetrock so as to form an opening substantially equal to the size and shape of the object.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
158 words
In a building construction system, a taping paper used for sealing a gap formed by a piece of wallboard and an object piercing said wallboard comprising a substantially flat surface having a central axis and an outer peripheral surface and a plurality of continuous concentric tear lines spaced at different radial distances from said central axis, said plurality of continuous tear lines being adapted to be torn so as to define an opening through which said object piercing said wallboard fits and further including a non-continuous tear line extending from said outer peripheral surface of said substantially flat surface in the direction of said central axis wherein said non-continuous tear line intersects said plurality of continuous concentric tear lines wherein said non-continuous tear line is adapted to be torn so as to define an opening for fitting said taping paper over said object such that said object fits into said opening defined by the torn continuous tear line.
Claim 2
Dependent Claim
158 words
In a building construction system, a taping paper used for sealing a gap formed by a piece of wallboard and an object piercing said wallboard comprising a substantially flat surface having a central axis and an outer peripheral surface and a plurality of continuous concentric tear lines spaced at different radial distances from said central axis, said plurality of continuous tear lines being adapted to be torn so as to define an opening through which said object piercing said wallboard fits and further including a non-continuous tear line extending from said outer peripheral surface of said substantially flat surface in the direction of said central axis wherein said non-continuous tear line intersects said plurality of continuous concentric tear lines wherein said non-continuous tear line is adapted to be torn so as to define an opening for fitting said taping paper over said object such that said object fits into said opening defined by the torn continuous tear line.
Claim 3
Dependent Claim
20 words
A taping paper according to claim 1 wherein said substantially flat surface has an inner peripheral surface defining a hole.
Claim 4
Dependent Claim
22 words
A taping paper according to claim 1 wherein said non-continuous tear line extends from said outer peripheral surface to said central axis.
Claim 5
Dependent Claim
23 words
A taping paper according to claim 2 wherein said non-continuous tear line extends from said outer peripheral surface to said inner peripheral surface.
Claim 6
Dependent Claim
20 words
A taping paper according to claim 1 wherein said said plurality of continuous concentric tear lines are circular in shape.
Claim 7
Dependent Claim
144 words
In a building construction system, a taping paper used for sealing a gap formed by a piece of wallboard and an object piercing said wallboard comprising a substantially flat surface having a central axis and an outer peripheral surface and a plurality of continuous concentric tear lines spaced at different radial distances from said central axis, said plurality of continuous tear lines being adapted to be torn so as to define an opening through which said object piercing said wallboard fits and further including a slit extending from said outer peripheral surface of said substantially flat surface in the direction of said central axis wherein said slit intersects said plurality of continuous concentric tear lines so as to define an opening for fitting said taping paper over said object such that said object fits into said opening defined by the torn continuous tear line.
Claim 8
Dependent Claim
144 words
In a building construction system, a taping paper used for sealing a gap formed by a piece of wallboard and an object piercing said wallboard comprising a substantially flat surface having a central axis and an outer peripheral surface and a plurality of continuous concentric tear lines spaced at different radial distances from said central axis, said plurality of continuous tear lines being adapted to be torn so as to define an opening through which said object piercing said wallboard fits and further including a slit extending from said outer peripheral surface of said substantially flat surface in the direction of said central axis wherein said slit intersects said plurality of continuous concentric tear lines so as to define an opening for fitting said taping paper over said object such that said object fits into said opening defined by the torn continuous tear line.
Claim 9
Dependent Claim
20 words
A taping paper according to claim 6 wherein said substantially flat surface has an inner peripheral surface defining a hole.
Claim 10
Dependent Claim
20 words
A taping paper according to claim 6 wherein said slit extends from said outer peripheral surface to said central axis.
Claim 11
Dependent Claim
21 words
A taping paper according to claim 7 wherein said slit extends from said outer peripheral surface to said inner pripheral surface.
Claim 12
Dependent Claim
20 words
A taping paper according to claim 6 wherein said said plurality of continuous concentric tear lines are circular in shape.
