Abstract
Abstract A freely rotatable open cell sponge-like roller is disposed below the usual distributor for receiving shampoo in liquid form. A driven rotary brush is disposed adjacent the roller, with the brush bristles impinging upon and squeezing the roller to transform the shampoo from liquid to foam. The foam is carried by the brush to the nap surface and is worked into the nap by the brush.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. a liqUid distributor, b. means to supply liquid shampoo to said distributor, c. a freely rotatable cellular compressible member disposed below said distributor for receiving liquid from said distributor, d. rotatable brush means disposed adjacent said member and with said brush means having bristles compressibly overlapping the peripheral portion of said freely rotatable member, e. and means to rotatably drive said brush means to thereby rotate and knead the peripheral portion of said freely rotatable member to create foam from said shampoo liquid.
Claim 2
Dependent Claim
103 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. a liqUid distributor, b. means to supply liquid shampoo to said distributor, c. a freely rotatable cellular compressible member disposed below said distributor for receiving liquid from said distributor, d. rotatable brush means disposed adjacent said member and with said brush means having bristles compressibly overlapping the peripheral portion of said freely rotatable member, e. and means to rotatably drive said brush means to thereby rotate and knead the peripheral portion of said freely rotatable member to create foam from said shampoo liquid.
Claim 3
Dependent Claim
96 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. a liquid distributor, b. means to supply liquid shampoo to said distributor, c. an elongated cellular compressible roller disposed below said distributor for receiving liquid from said distributor, d. a rotatable brush disposed adjacent said roller and with said brush having rows of bristles compressibly overlapping the peripheral portion of said roller, e. and means to rotatably drive said brush to thereby knead the peripheral portion of said roller to create foam from said shampoo liquid.
Claim 4
Dependent Claim
96 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. a liquid distributor, b. means to supply liquid shampoo to said distributor, c. an elongated cellular compressible roller disposed below said distributor for receiving liquid from said distributor, d. a rotatable brush disposed adjacent said roller and with said brush having rows of bristles compressibly overlapping the peripheral portion of said roller, e. and means to rotatably drive said brush to thereby knead the peripheral portion of said roller to create foam from said shampoo liquid.
Claim 5
Dependent Claim
21 words
In the device of claim 2: means to mount said roller for free rotation in response to rotation of said brush.
Claim 6
Dependent Claim
25 words
In the device of claim 2: means to concentrate the said liquid shampoo in the peripheral portion of said roller during rotation of said brush.
Claim 7
Dependent Claim
46 words
The device of claim 4 in which said liquid concentrating means comprises: means mounting said roller for free rotation thereof in response to rotation of said brush so that centrifugal force will cause said liquid shampoo to be concentrated in said peripheral portion of said roller.
Claim 8
Dependent Claim
27 words
The device of claim 2 wherein the said rows of brush bristles are helical so that brush rotation causes a progressive continuous kneading action on said roller.
