Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
195 words
A brush construction comprising a generally planar brush back having opposite faces, and a multitude of integral bristles projecting from one face of said brush back, said brush back being self-sustaining in its normally flat condition and being fabricated of a plastic material having flexibility enabling said brush back to be bent or folded upon itself, and being provided with generally circumferential rib means defining upstanding side and end walls stiffening the brush back against bending, said rib means being absent only along a medial region to facilitate the bending of said brush back along said medial region to fold upon itself toward the other face of said brush back to swing said bristles into angular relation with each other for brushing engagement with an internal surface; and a resilient rubbing sponge secured on said other brush back face and conformably engageable within the upstanding side and end walls formed by said generally circumferential rib means; whereby the flexural action of the plastic material enabling the brush back to be restored to its unflexed condition, and whereby said sponge also serves to enhance the restoring of said brush back to its unflexed normally flat condition.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
45 words
A brush construction according to claim 1, said brush back being bendable to an obtuse angle, said bristles being normally generally perpendicular to said brush back in general parallelism with each other and swingable on said bending to extend generally oppositely away from each other.
Claim 4
Dependent Claim
14 words
A brush construction according to Claim 1, said sheet being perforate to pass liquid.
Claim 5
Dependent Claim
50 words
A brush construction according to Claim 3, said rib means comprising longitudinal and end flanges on said other face of said sheet and being interrupted at oppositely spaced medial locations by notches cut out of the end flanges to facilitate bending of said brush back along the medial region thereof.
