Brush device for dispensing liquid material by using plunger means

Abstract

Brush device which dispenses fluid material such as toothpaste or paint is equipped with a dispenser and brush. The dispenser comprises a liquid material container and a plunger therein which is manually actuated to pressure out the liquid material from the container. The brush body is detachably connected to a liquid material container using a screw mate and elongated hub engagement. The material is pressured by the plunger to enter into a series of conduits incorporated into a body of the brush and, through the openings of the head of the brush, finally pushed out to the bristles of the brush. When the fluid in the container is completely used up, the dispenser is reloaded with new fluid by sliding a plunger of the dispenser.

1 . A brush device for dispensing fluid material comprising:
 a dispenser forming a liquid-containing container, said dispenser ejecting fluid material from a container by sliding forward a plunger therein and sucking up fluid material into a container by sliding backward said plunger, said dispenser having a external screw threaded collar and a elongated hub at and toward the opposite side of said plunger;   a brush including a brush body and a bristle-carrying brush head, said brush head formed integrally with said brush body and having outlet openings; and   a channel delivering said fluid material from said container to said bristles, the channel formed axially extending through said external screw threaded collar and elongated hub of said dispenser, said brush body and head, and outlet openings toward the region of said bristles;   wherein the part of said channel formed in said brush body includes internal screw threads and a cylindrical conduit,   wherein said internal screw threads is adapted to mate with said external screw threaded collar, and   wherein said cylindrical conduit substantially fits with the diameter of said elongated hub.   
   
   
       2 . A brush device as defined in  claim 1 , wherein said opening has a plurality of apertures. 
   
   
       3 . A brush device as defined in  claim 1 , wherein said elongated hub substantially fits with the diameter of an opening of separate toothpaste tube. 
   
   
       4 . A brush device as defined in  claim 1 , wherein said brush is a toothbrush and said fluid material is toothpaste. 
   
   
       5 . A brush device as defined in  claim 1 , wherein said brush is a paint brush and said fluid material is paint. 
   
   
       6 . A brush device as defined in  claim 1 , wherein said elongated hub is about 1 centimeter in length. 
   
   
       7 . A brush device for dispensing fluid material comprising:
 a dispenser forming a liquid-containing container, said dispenser ejecting fluid material from a container by sliding forward a plunger therein and sucking up fluid material into a container by sliding backward said plunger, said dispenser having a external screw threaded collar and a elongated hub at and toward the opposite side of said plunger;   a brush including in order a brush body, brush neck, and a bristle-carrying brush head, said brush neck formed integrally with said brush neck and brush head, and said brush head having outlet openings; and   a channel delivering said fluid material from said container to said bristles, the channel formed axially extending through said external screw threaded collar and elongated hub of said dispenser, said brush body and brush neck and brush head, and outlet opening toward the region of said bristles;   wherein the part of said channel formed in said brush body includes internal screw threads and a cylindrical conduit,   wherein said screw threads threadedly mate said external screw threaded collar,   wherein said cylindrical conduit substantially fits with the diameter of said elongated hub, and   wherein the part of said channel formed in said brush neck being tapered toward the part of said channel formed in said brush head, and the diameter of said part of channel formed in said brush head being smaller than the diameter of said part of channel formed in said brush body.   
   
   
       8 . A brush device as defined in  claim 7 , wherein said elongated hub substantially fits with the diameter of an opening of a separate toothpaste tube. 
   
   
       9 . A brush device as defined in  claim 7 , wherein said brush is a toothbrush and said fluid material is toothpaste. 
   
   
       10 . A brush device as defined in  claim 7 , wherein said brush is a paint brush and said fluid material is paint. 
   
   
       11 . A brush device as defined in  claim 7 , wherein said elongated hub is about 1 centimeter in length. 
   
   
       12 . A brush which is used in combination with a fluid material dispenser detachably connected thereat, comprising;
 a brush body;   a bristle-carrying brush head, said brush head having outlet openings;   a brush neck, said brush neck formed integrally with said brush neck and brush head; and   a channel delivering fluid material to said bristles, the channel formed axially extending through said brush body and brush neck and brush head, and outlet opening toward the region of said bristles formed within said brush head;   wherein the part of said channel formed in said brush body includes internal screw threads and a cylindrical conduit, and   wherein the part of said channel formed in said brush neck being tapered toward the part of said channel formed in said brush head, and the diameter of said part of channel formed in said brush head being smaller than the diameter of said part of channel formed in said brush body.   
   
   
       13 . A brush as defined in  claim 12 , wherein said brush is a toothbrush and said fluid material is toothpaste. 
   
   
       14 . A brush as defined in  claim 12 , wherein said brush is a paint brush and said fluid material is paint. 
   
   
       15 . A brush as defined in  claim 12 , wherein said cylindrical conduit is about 1 centimeter in length.
