Abstract
Abstract A massaging and scrubbing device for the human back consists of a closed cell foam plastic base member of relatively high density and rigidity and a layer of closed cell foam plastic sheet material adhered to the base member. The sheet material has a mildly abrasive exposed surface and high compressibility and flexibility so that all recesses on a human back are engaged by the sheet as the back is moved back and forth while pressed against the device. The device can be used with or without soap and water applied thereto depending on whether one wants only a massage or a combined back scrub and massage.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
198 words
A back massage and scrubbing device comprising a closed cell foam plastic base member having side edges of a selected height, a front face and a rear face which is co-extensive with said front face and planar throughout its extent, said planar rear face being directly engageable with a support surface, said base member having sufficient rigidity to prevent said member from buckling when the pressure force of a user's back is exerted thereagainst, a layer of closed cell flexible and compressible foam plastic sheet material of less thickness than the height of the side edges of said base member uniformly adhered to at least the front face of said base member, said flexible foam plastic sheet material having an exposed face characterized by shallow pits disposed over the entire surface of said exposed face with shallow protuberances being disposed between said pits, said pits and protuberances together defining an abrasive surface by which a user's back pressed against said surface may be scrubbed and massaged without discomfort during relative movement between said surface and said back, and said base member includes a protruding and upstanding neck engaging part over which said flexible foam plastic sheet material extends.
Claim 2
Dependent Claim
198 words
A back massage and scrubbing device comprising a closed cell foam plastic base member having side edges of a selected height, a front face and a rear face which is co-extensive with said front face and planar throughout its extent, said planar rear face being directly engageable with a support surface, said base member having sufficient rigidity to prevent said member from buckling when the pressure force of a user's back is exerted thereagainst, a layer of closed cell flexible and compressible foam plastic sheet material of less thickness than the height of the side edges of said base member uniformly adhered to at least the front face of said base member, said flexible foam plastic sheet material having an exposed face characterized by shallow pits disposed over the entire surface of said exposed face with shallow protuberances being disposed between said pits, said pits and protuberances together defining an abrasive surface by which a user's back pressed against said surface may be scrubbed and massaged without discomfort during relative movement between said surface and said back, and said base member includes a protruding and upstanding neck engaging part over which said flexible foam plastic sheet material extends.
Claim 3
Dependent Claim
21 words
The back massage and scrubbing device of claim 1, wherein said pits and protruberances are defined by substantially vertically extending striations.
Claim 4
Dependent Claim
39 words
The back massage and scrubbing device of claim 1, wherein said pits are defined by irregularly shaped, randomly disposed shallow recesses, said protuberances being defined by the portions of the surface of said face not occupied by said recesses.
Claim 5
Dependent Claim
13 words
The massage and scrubbing device of claim 1, wherein said plastic is polyethylene.
Claim 6
Dependent Claim
28 words
The massage and scrubbing device of claim 1, wherein said base member has a size and configuration conforming substantially to those of the back of an average human.
Claim 7
Dependent Claim
56 words
The massage and scrubbing device of claim 1, wherein the flexibility and compressibility of said sheet material is selected so that it yields sufficiently to enable all recesses in a user'back to be engaged by the sheet material during movement of said back relative to said device and while said back and device are pressed together.
Claim 8
Dependent Claim
27 words
The back massage and scrubbing device of claim 1, including means for releasably mounting said device in a substantially immovable position for engagement by a user's back.
Claim 9
Dependent Claim
72 words
The massage and scrubbing device of claim 7, wherein the releasable mounting means comprises at least one of male and female Velcro members carried on the rear face of said base member for cooperating with the other of said Velcro members which is adapted to be fixed to a rigid support surface in a position to be engaged by said one of said members on the rear face of said base member.
