Abstract
Abstract A body scrubbing apparatus such as a stationary back scrubber is disclosed for attachment to a wall which comprises a resilient sponge device having a reservoir at the top thereof for gravity feeding liquid detergent from the reservoir to the bottom of the porous member of sponge. In one embodiment a sponge having a gradient density increasing from the reservoir downwardly toward the bottom of the porous member or a sponge is provided to minimize pooling or collection of liquid detergent at the bottom of the sponge or porous member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A body scrubbing apparatus for attachment to a wall comprising a an absorbent resilient scrubbing means, said abosrbent scrubbing means having liquid detergent reservoir means mounted at the top thereof for gravity feeding liquid detergent downwardly through said absorbent scrubbing means, the density of said absorbent scrubbing means increasing in a direction from said detergent reservoir means towards the bottom of said absorbent scrubbing means to minimize the pooling of liquid detergent at the bottom of said absorbent scrubbing means, wall securing means operativey connected to the back of said absorbent means for attachment to a wall surface, said absorbent scrubbing means is mounted on backing means, the upper portion of said backing means having recess means therein, the upper portion of said absorbent scrubbing means extending across said recess to thereby form said reservoir for a liquid detergent, said backing means having said wall securing means on the face thereof opposite said absorbent scrubbing means.
Claim 2
Dependent Claim
156 words
A body scrubbing apparatus for attachment to a wall comprising a an absorbent resilient scrubbing means, said abosrbent scrubbing means having liquid detergent reservoir means mounted at the top thereof for gravity feeding liquid detergent downwardly through said absorbent scrubbing means, the density of said absorbent scrubbing means increasing in a direction from said detergent reservoir means towards the bottom of said absorbent scrubbing means to minimize the pooling of liquid detergent at the bottom of said absorbent scrubbing means, wall securing means operativey connected to the back of said absorbent means for attachment to a wall surface, said absorbent scrubbing means is mounted on backing means, the upper portion of said backing means having recess means therein, the upper portion of said absorbent scrubbing means extending across said recess to thereby form said reservoir for a liquid detergent, said backing means having said wall securing means on the face thereof opposite said absorbent scrubbing means.
Claim 3
Dependent Claim
15 words
The body scrubbing apparatus of claim 1 where said backing means comprises a resilient backing.
Claim 4
Dependent Claim
16 words
The body scrubbing apparatus of claim 2 where said securing means comprises a substantially waterproof adhesive.
Claim 5
Dependent Claim
87 words
The body scrubbing apparatus of claim 1 where said absorbent scrubbing means comprises a plurality of abosrbent scrubbing elements extending laterally to form opposed substantially horizontal edges, said edges of each being in an abutting relation for feeding liquid detergent from one absorbent scrubbing element to another, the density of each of said absorbent scrubbing elements increasing in a direction from said detergent reservoir toward the bottom of said absorbent scrubbing means to minimize the pooling of liquid detergent at the bottom of said abosrbent scrubbing means.
Claim 6
Dependent Claim
93 words
The body scrubbing apparatus of claim 1 where said absorbent scrubbing means comprises a plurality of absorbent scrubbing elements extending laterally to form opposed substantially horizontal edges, said edges of each being in an abutting relation for feeding liquid detergent from one absorbent scrubbing element to another, the density of each of said abosrbent scrubbing elements beneath the absorbent scrubbing element extending across said reservoir being greater than the density of said absorbent scrubbing element immediately above it to minimize the pooling of liquid detergent at the bottom of said body scrubbing apparatus.
Claim 7
Dependent Claim
24 words
The body scrubbing apparatus of claim 4 where said backing means comprises a resilient backing and said securing means comprises a substantially waterproof adhesive.
Claim 8
Dependent Claim
24 words
The body scrubbing apparatus of claim 5 where said backing means comprises a resilient backing and said securing means comprise a substantially waterproof adhesive.
