Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 197 words
A denture scrubbing brush comprising a planar oval shaped member having first and second faces that are parallel to and opposite each other, a plurality of bristles affixed to and extending from said first face, a grasping handle affixed to said second face, said handle having one end attached to the second face and a spaced second end for grasping by the user, such that the user hand is inserted between the spaced second end and the brush second face when in use, the handle attachment to the brush being along the vertical centerline of the brush faces, and the spaced second end of the handle being offset to one side from the vertical centerline to a point where the second end projects beyond the edge of the planar faces, whereby said angle of attachment causes said grasping handle to become strategically placed parallel to, but offset from, a longitudinal plane perpendicular to said first face, such that when the brush bristles are in cleaning contact with denture surfaces, the user hand is offset from the denture which allows a user to safely and effectively clean said dentures by exercising a scrubbing motion on said denture surfaces.
Claim 2
Dependent Claim 197 words
A denture scrubbing brush comprising a planar oval shaped member having first and second faces that are parallel to and opposite each other, a plurality of bristles affixed to and extending from said first face, a grasping handle affixed to said second face, said handle having one end attached to the second face and a spaced second end for grasping by the user, such that the user hand is inserted between the spaced second end and the brush second face when in use, the handle attachment to the brush being along the vertical centerline of the brush faces, and the spaced second end of the handle being offset to one side from the vertical centerline to a point where the second end projects beyond the edge of the planar faces, whereby said angle of attachment causes said grasping handle to become strategically placed parallel to, but offset from, a longitudinal plane perpendicular to said first face, such that when the brush bristles are in cleaning contact with denture surfaces, the user hand is offset from the denture which allows a user to safely and effectively clean said dentures by exercising a scrubbing motion on said denture surfaces.
Claim 3
Dependent Claim 27 words
The denture scrubbing brush of claim 1 where said grasping handle is configured for use by either the right or left hand, and fingers, of said user.
