Abstract
Abstract A disposable scrub brush, preferably made of chemical foam, and which is sufficiently economical to warrant discarding after a single usage. The brush, while being highly desirable for surgical usage for scrubbing the arms and hands prior to an operation, may also be utilized for numerous other purposes including use as a cosmetic brush, industrial usage, and many others as will be apparent to one skilled in the art. The brush carries its own soap or detergent supply and this, of course, may be varied in accordance with the intended usage of the brush.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
100 words
A disposable brush comprising: an elongated semi-rigid chemical foam block; the foam of said block being of the closed cell type whereby the block will only adsorb and not absorb and therefore will retain its shape and texture throughout rough washings; a series of longitudinal cuts in one face of said block defining spaced grooves and providing a good scrubbing surface; and said foam block having a grain lengthwise of the block and said grooves extending generally parallel to said grain whereby the brush is more compressible in direction across the grain and grooves than with said grain and grooves.
Claim 2
Dependent Claim
100 words
A disposable brush comprising: an elongated semi-rigid chemical foam block; the foam of said block being of the closed cell type whereby the block will only adsorb and not absorb and therefore will retain its shape and texture throughout rough washings; a series of longitudinal cuts in one face of said block defining spaced grooves and providing a good scrubbing surface; and said foam block having a grain lengthwise of the block and said grooves extending generally parallel to said grain whereby the brush is more compressible in direction across the grain and grooves than with said grain and grooves.
Claim 3
Dependent Claim
42 words
A disposable brush according to claim 1, said grooves being separated by longitudinal ribs; and the ribs along the longitudinal side margins of said face being wider and stiffer than the ribs between said side marginal ribs to facilitate scrubbing the fingernails.
Claim 4
Dependent Claim
94 words
A disposable brush comprising: a semi-rigid chemical foam block; the foam of said block being of the closed cell type whereby the block will only adsorb and not absorb and therefore will retain its shape and texture throughout rough washings; a series of cuts in one face of said block defining spaced grooves and providing a good scrubbing surface; a series of cuts in the opposite face of said block of different depth than those in said one face and defining grooves; and a cleansing substance carried within a plurality of the deeper grooves.
Claim 5
Dependent Claim
94 words
A disposable brush comprising: a semi-rigid chemical foam block; the foam of said block being of the closed cell type whereby the block will only adsorb and not absorb and therefore will retain its shape and texture throughout rough washings; a series of cuts in one face of said block defining spaced grooves and providing a good scrubbing surface; a series of cuts in the opposite face of said block of different depth than those in said one face and defining grooves; and a cleansing substance carried within a plurality of the deeper grooves.
Claim 6
Dependent Claim
45 words
A disposable brush according to claim 3: said grooves being separated by longitudinal ribs; and the outside ribs between the edge of the block and the next inside groove on said one face being wider than the other ribs to facilitate cleansing of the nails.
Claim 7
Dependent Claim
119 words
A disposable brush comprising: a semi-rigid chemical foam block; the foam of said block being of the closed cell type whereby the block will only adsorb but not absorb and therefore will retain its shape and texture throughout rough washings; a series of cuts in one face of said block defining spaced grooves; a second series of cuts in said face running at an angle to said first series of cuts, thereby defining rows of polygonal projections between the grooves each having a plurality of scrubbing edges on the outer end thereof; a series of cuts in the opposite face of said block defining spaced grooves separated by longitudinal ribs; and a cleansing medium in certain of said grooves.
Claim 8
Dependent Claim
119 words
A disposable brush comprising: a semi-rigid chemical foam block; the foam of said block being of the closed cell type whereby the block will only adsorb but not absorb and therefore will retain its shape and texture throughout rough washings; a series of cuts in one face of said block defining spaced grooves; a second series of cuts in said face running at an angle to said first series of cuts, thereby defining rows of polygonal projections between the grooves each having a plurality of scrubbing edges on the outer end thereof; a series of cuts in the opposite face of said block defining spaced grooves separated by longitudinal ribs; and a cleansing medium in certain of said grooves.
Claim 9
Dependent Claim
36 words
The brush of claim 5, wherein the outside ribs between the edge of the block and the next inside groove in said opposite face are wider than the other ribs to facilitate cleansing of the nails.
