Abstract
Abstract A device for dispensing a fluid or plastic material from the chamber of a housing to brush bristles connected to said housing so that the material, such as a cleansing material, can be used in combination with the brush bristles. A reciprocal rod has an annular cavity adapted to fit a plurality of telescopic cylindrical members therein. A piston is preferably connected to one of said members and forms a movable wall of said chamber. Reciprocal movement of the rod causes the piston to be shifted longitudinally within the housing to selectively force material from said chamber through a pressure sensitive valve to the bristles. The telescopic members allow for the device to be of a minimum length while still allowing for substantially complete dispensing of the material within the chamber. Optionally, a separate container can be used to supply material to the housing chamber.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
A device for dispensing a fluid material comprising: a hollow housing, said housing having a chamber therein adapted to contain a supply of the material; brush bristles connected to said housing; a reciprocal rod within said housing, one end of said rod having an annular cavity therein, said one end having an inwardly extending flange thereon; a plurality of telescopic cylindrical members adapted to be positioned within said cavity when unexpanded, each of said cylindrical members having a detent on the outer surface thereof, at least the outer member of said cylindrical members having one end with an outwardly extending flange and the other end with an inwardly extending flange; a piston positioned within said housing, said piston forming a movable wall of said chamber, said piston adapted to be shifted longitudinally within said housing by reciprocal movement of said rod; a discharge passage connecting said chamber to said bristles; and a valve for opening and closing said discharge passage, whereby the fluid material can be selectively dispensed to said bristles.
Claim 2
Independent Claim
171 words
A device for dispensing a fluid material comprising: a hollow housing, said housing having a chamber therein adapted to contain a supply of the material; brush bristles connected to said housing; a reciprocal rod within said housing, one end of said rod having an annular cavity therein, said one end having an inwardly extending flange thereon; a plurality of telescopic cylindrical members adapted to be positioned within said cavity when unexpanded, each of said cylindrical members having a detent on the outer surface thereof, at least the outer member of said cylindrical members having one end with an outwardly extending flange and the other end with an inwardly extending flange; a piston positioned within said housing, said piston forming a movable wall of said chamber, said piston adapted to be shifted longitudinally within said housing by reciprocal movement of said rod; a discharge passage connecting said chamber to said bristles; and a valve for opening and closing said discharge passage, whereby the fluid material can be selectively dispensed to said bristles.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein said piston controls the material pressure within said chamber and said valve is responsive to said material pressure.
Claim 4
Dependent Claim
49 words
The device of claim 2 wherein said detent on said outer member of said cylindrical members is adapted to contact said one end of said rod, and the detent on each of the remaining cylindrical members is adapted to contact said other end of the immediately surrounding cylindrical members.
Claim 5
Dependent Claim
84 words
The device of claim 3 wherein said outwardly extending flange of said outer cylindrical member is adapted to contact said inwardly extending flange of said one end of said rod whereby said outer cylindrical member will be mounted for movement in unison with said rod when said outwardly extending flange of said outer cylindrical member contacts said inwardly extending flange of said one end of said rod and said detent on said outer member is in contact with said one end of said rod.
Claim 6
Dependent Claim
60 words
The device of claim 4 wherein said detents are resilient, each of said cylindrical members which has another cylindrical member telescoping therein has a longitudinal slot to accommodate the detent of the cylindrical member immediately telescoping therein, and said one end of said rod has a longitudinal slot defined thereon adapted to accommodate said detent of said outer cylindrical member.
Claim 7
Dependent Claim
30 words
The device of claim 4 also including a supply container having a reservoir of fluid material contained therein, and a fluid line connected to said supply container and said housing.
Claim 8
Dependent Claim
24 words
The device of claim 6 also including a second valve for selectively allowing addition of fluid material from said supply container to said chamber.
Claim 9
Dependent Claim
45 words
The device of claim 7 wherein said supply container has a sealed pressurized capsule therein, said sealed capsule containing said fluid material, and means for allowing passage of material from said capsule to said fluid line by connection of said capsule to said fluid line.
