Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
An improved dispensing brush comprising a flexible resilient dome element having a size and configuration to accommodate gripping by a human hand and an open bottom, said dome having an inwardly extending peripheral flange about the open bottom thereof and said dome also having a projection above said flange for defining an annular lateral internal groove between said flange and projection, said flange having at least one aperture therethrough, a substantially rigid circular floor member with bristles depending therefrom disposed across the open bottom of said dome upon said flange in said groove in rotary slidable engagement with same, said floor member having at least one aperture therethrough above said housing flange in radial alignment therewith, and means extending from said floor member for sliding same angularly within said groove for controllably aligning the apertures in floor and flange whereby the interior of said dome is opened for dispensing of material therefrom as by squeezing of said dome.
Claim 2
Dependent Claim
158 words
An improved dispensing brush comprising a flexible resilient dome element having a size and configuration to accommodate gripping by a human hand and an open bottom, said dome having an inwardly extending peripheral flange about the open bottom thereof and said dome also having a projection above said flange for defining an annular lateral internal groove between said flange and projection, said flange having at least one aperture therethrough, a substantially rigid circular floor member with bristles depending therefrom disposed across the open bottom of said dome upon said flange in said groove in rotary slidable engagement with same, said floor member having at least one aperture therethrough above said housing flange in radial alignment therewith, and means extending from said floor member for sliding same angularly within said groove for controllably aligning the apertures in floor and flange whereby the interior of said dome is opened for dispensing of material therefrom as by squeezing of said dome.
Claim 3
Dependent Claim
33 words
The improved dispensing brush of claim 1 further defined by said dome being formed of a plastic having a low coefficient of friction whereby said floor member is readily rotated in said groove.
Claim 4
Dependent Claim
38 words
The dispensing brush of claim 1 further defined by said dome having a thickened lower periphery so as to have substantially no flexibility thereat whereby said groove and flange retains the shape thereof despite flexing of the dome.
Claim 5
Dependent Claim
81 words
The improved dispensing brush of claim 1 further defined by said dome defining a peripheral slot extending from said groove to the exterior of the dome for a limited angular distance about the dome, and said means extending from the floor member comprising a radial extension of the floor member disposed through said slot exteriorly of the dome for movement along the slot to rotate the floor member in the groove to align apertures in the floor member and dome flange.
Claim 6
Dependent Claim
71 words
The improved dispensing brush of claim 4 further defined by said dome including an internal projection in said groove, said floor member having a peripheral indentation therein, and a compression spring disposed in said groove peripherally thereof within said peripheral indentation in said floor member between a shoulder formed thereon and said projection in said groove for urging said plate angularly to dispose said floor and flange apertures out of alignment.
