Abstract

A dispensing toothbrush assembly includes a toothbrush that may be manipulated. The toothbrush has a conduit therein. The conduit transports a fluid into the toothbrush thereby facilitating the toothbrush to clean teeth. A dispensing unit is provided and the dispensing unit contains toothpaste. The dispensing unit may be manipulated thereby facilitating the dispensing unit to urge the toothpaste outwardly from the toothbrush.

Claims (21)

1. A dispensing toothbrush assembly being configured to selectively dispense a toothpaste, said assembly comprising:

a toothbrush being configured to be manipulated, said toothbrush having a conduit therein wherein said conduit is configured to transport a fluid into said toothbrush thereby facilitating said toothbrush to clean teeth, said toothbrush having a first end, a second end, a front side and a back side, said first end being open, said conduit extending upwardly from said first end and outwardly from said front side, said toothbrush flaring outwardly adjacent to said second end to define a flange on said second end, said flange having an inner surface, said toothbrush having a plurality of bristles, each of said bristles being positioned on said front side, said bristles being aligned with said second end, said bristles being aligned with said conduit; and

a dispensing unit being configured to contain toothpaste, said dispensing unit being configured to be manipulated thereby facilitating said dispensing unit to urge the toothpaste outwardly from said toothbrush, said dispensing unit comprises a cylinder being configured to be gripped, said cylinder having a top end, a bottom end and an outer wall extending therebetween, said cylinder being substantially hollow wherein said cylinder is configured to contain the toothpaste, said outer wall having an inside surface;

a shaft being positioned within said cylinder, said shaft being threaded; and

a knob being rotatably coupled to said bottom end of said cylinder wherein said knob is configured to be manipulated, said shaft having a bottom end being coupled to said knob, said shaft extending upwardly from said knob such that said knob rotates said shaft, said shaft having a free end positioned within said cylinder opposite said bottom end, said conduit being positioned in linear alignment with said shaft.

2. The assembly according to claim 1 , further comprising:

a flange having an inner surface; and

a nozzle being coupled to said top end of said cylinder, said nozzle having a distal end with respect to said top end and an outer surface, said distal end having an opening extending into an interior of said cylinder, said outer surface being threaded, said inner surface of said flange threadably engaging said outer surface of said nozzle such that said toothbrush is removably coupled to said cylinder, said conduit being in fluid communication with said nozzle.

3. The assembly according to claim 1 , further comprising:

a nozzle;

a disk being positioned within said cylinder, said disk having an outer edge, said outer edge engaging said inner surface of said cylinder, said shaft extending through said disk having said disk threadably engaging said shaft, said disk being urged upwardly along said shaft when said knob is rotated wherein said disk is configured to urge the toothpaste outwardly through said nozzle thereby facilitating the toothpaste to be dispensed onto said bristles.

4. The assembly according to claim 1 , further comprising a valve being movably coupled to said toothbrush, said valve being in fluid communication with said conduit wherein said valve is configured to selectively restrict and allow the toothpaste to flow through said conduit, said valve including a button being positioned on said back side of said toothbrush wherein said button is configured to be manipulated, said button urging said valve between an open position and a closed position.

5. A dispensing toothbrush assembly being configured to selectively dispense a toothpaste, said assembly comprising:

a toothbrush being configured to be manipulated, said toothbrush having a conduit therein wherein said conduit is configured to transport a fluid into said toothbrush thereby facilitating said toothbrush to clean teeth, said toothbrush having a first end, a second end, a front side and a back side, said first end being open, said conduit extending upwardly from said first end toward and outwardly from said front side, said toothbrush flaring outwardly adjacent to said second end to define a flange on said second end, said flange having an inner surface, said toothbrush having a plurality of bristles, each of said bristles being positioned on said front side, said bristles being aligned with said second end, said bristles being aligned with said conduit; and

a dispensing unit being configured to contain a toothpaste, said dispensing unit being configured to be manipulated thereby facilitating said dispensing unit to urge the toothpaste outwardly from said toothbrush, said dispensing unit comprising:

a cylinder being configured to be gripped, said cylinder having a top end, a bottom end and an outer wall extending therebetween, said cylinder being substantially hollow wherein said cylinder is configured to contain the toothpaste, said outer wall having an inside surface,

a nozzle being coupled to said top end of said cylinder, said nozzle having a distal end with respect to said top end and an outer surface, said distal end having an opening extending into an interior of said cylinder, said outer surface being threaded, said inner surface of said flange threadably engaging said outer surface of said nozzle such that said toothbrush is removably coupled to said cylinder, said conduit being in fluid communication with said nozzle,

a shaft being positioned within said cylinder, said shaft being threaded,

a knob being rotatably coupled to said bottom end of said cylinder wherein said knob is configured to be manipulated, said shaft having a bottom end being coupled to said knob, said shaft extending upwardly from said knob such that said knob rotates said shaft, said shaft having a free end positioned within said cylinder opposite said bottom end, said conduit being positioned in linear alignment with said shaft, and

a disk being positioned within said cylinder, said disk having an outer edge, said outer edge engaging said inner surface of said cylinder, said shaft extending through said disk having said disk threadably engaging said shaft, said disk being urged upwardly along said shaft when said knob is rotated wherein said disk is configured to urge the toothpaste outwardly through said nozzle thereby facilitating the toothpaste to be dispensed onto said bristles, and

a valve being movably coupled to said toothbrush, said valve being in fluid communication with said conduit wherein said valve is configured to selectively restrict and allow the toothpaste to flow through said conduit, said valve including a button being positioned on said back side of said toothbrush wherein said button is configured to be manipulated, said button urging said valve between an open position and a closed position.
