Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A toothbrush comprising: a handle having a first handle surface and an opposed handle surface; a bristled head connected to said handle; an aperture disposed through said handle, from said first handle surface to said opposed handle surface, said aperture being defined by an aperture peripheral wall generally transverse to said handle surfaces and having an insert therein; said insert having a first non-slip insert surface forming a non-slip region on the first handle surface, an opposed insert surface being disposed essentially co-planar with the opposed handle surface, and an insert peripheral wall generally transverse to said insert surfaces; said aperture wall having an aperture shoulder extending into the aperture; said insert having an insert shoulder extending into the aperture; said shoulders being in face-to-face relationship and bearing against each other to resist a force attempting to translate the insert out of the aperture.
Claim 2
Dependent Claim
144 words
A toothbrush comprising: a handle having a first handle surface and an opposed handle surface; a bristled head connected to said handle; an aperture disposed through said handle, from said first handle surface to said opposed handle surface, said aperture being defined by an aperture peripheral wall generally transverse to said handle surfaces and having an insert therein; said insert having a first non-slip insert surface forming a non-slip region on the first handle surface, an opposed insert surface being disposed essentially co-planar with the opposed handle surface, and an insert peripheral wall generally transverse to said insert surfaces; said aperture wall having an aperture shoulder extending into the aperture; said insert having an insert shoulder extending into the aperture; said shoulders being in face-to-face relationship and bearing against each other to resist a force attempting to translate the insert out of the aperture.
Claim 3
Dependent Claim
59 words
The toothbrush of claim 1 wherein said insert shoulder faces toward said opposed handle surface and said aperture shoulder faces toward said first handle surface whereby said shoulders resist a force attempting to translate the insert out of the aperture in a direction from the first handle surface to the opposed handle surface but not in an opposite direction.
Claim 4
Dependent Claim
63 words
The toothbrush of claim 2 wherein said aperture further comprises a bridging portion extending across the aperture and joining opposed portions of the aperture peripheral wall, said bridging portion bearing against the first non-slip insert surface to resist a force attempting to translate the insert out of the aperture in the direction of from the opposed handle surface to the first handle surface.
Claim 5
Dependent Claim
18 words
The toothbrush of claim 1 wherein said insert comprises a compressible material and is compression-fit within said aperture.
Claim 6
Dependent Claim
15 words
The toothbrush of claim 1 wherein said opposed insert surface is also a non-slip surface.
Claim 7
Dependent Claim
15 words
The toothbrush of claim 1 wherein said handle comprises a plurality of apertures and inserts.
Claim 8
Dependent Claim
183 words
A toothbrush comprising: a handle having a first handle surface and an opposed handle surface; a bristled head connected to said handle; an aperture disposed through said handle, from said first handle surface to said opposed handle surface, said aperture being defined by an aperture peripheral wall generally transverse to said handle surfaces and having an insert therein; said insert having a first non-slip insert surface forming a non-slip region on the first handle surface, an opposed insert surface being disposed essentially co-planar with the opposed handle surface, and an insert peripheral wall generally transverse to said insert surfaces; said toothbrush having securing means for securing said insert within said aperture, said securing means comprising an interlocking region on the peripheral wall of the insert and an interlocking region on the peripheral wall of the aperture; wherein one of said interlocking regions is a recess, recessed from the aperture and the other is a projection, projecting into the aperture; said recess and said projection cooperating to bear against each other and resist any force tending to translate the insert out of the aperture.
Claim 9
Dependent Claim
183 words
A toothbrush comprising: a handle having a first handle surface and an opposed handle surface; a bristled head connected to said handle; an aperture disposed through said handle, from said first handle surface to said opposed handle surface, said aperture being defined by an aperture peripheral wall generally transverse to said handle surfaces and having an insert therein; said insert having a first non-slip insert surface forming a non-slip region on the first handle surface, an opposed insert surface being disposed essentially co-planar with the opposed handle surface, and an insert peripheral wall generally transverse to said insert surfaces; said toothbrush having securing means for securing said insert within said aperture, said securing means comprising an interlocking region on the peripheral wall of the insert and an interlocking region on the peripheral wall of the aperture; wherein one of said interlocking regions is a recess, recessed from the aperture and the other is a projection, projecting into the aperture; said recess and said projection cooperating to bear against each other and resist any force tending to translate the insert out of the aperture.
Claim 10
Dependent Claim
63 words
The toothbrush of claim 7 wherein said aperture further comprises a bridging portion extending across the aperture and joining opposed portions of the aperture peripheral wall, said bridging portion bearing against the first non-slip insert surface to resist a force attempting to translate the insert out of the aperture in the direction of from the opposed handle surface to the first handle surface.
Claim 11
Dependent Claim
18 words
The toothbrush of claim 7 wherein said insert comprises a compressible material and is compression-fit within said aperture.
Claim 12
Dependent Claim
15 words
The toothbrush of claim 7 wherein said opposed insert surface is also a non-slip surface.
Claim 13
Dependent Claim
