Abstract
A refillable toothpaste dispensing toothbrush has a toothpaste containing capsule for dispensing toothpaste through the bristle head of the toothbrush. The toothpaste capsule can be filled using any standard toothpaste tube. Grooves in the toothpaste passageway prevent clogging of toothpaste in the toothbrush. In an alternate embodiment, the dispensing toothbrush also contains a sonic vibrating device.
Claims9
A toothpaste dispensing toothbrush for storing and dispensing toothpaste comprising, in combination:
- a replaceable toothbrush neck portion with an internal passageway for communicating toothpaste from a neck inlet port located at a lower attach end of said neck to a toothpaste outlet port located at an upper bristle end of said neck, wherein said upper bristle end has a plurality of bristles formed around said toothpaste outlet port of said internal passage;
- a hollow toothbrush body having a tapered upper end with a top surface, a body outlet port located on said top surface, and a tubular lower end with an open base for receiving a toothpaste capsule;
- a mid surface separating said tapered end from said tubular end, said mid surface having a body inlet port attached thereto;
- a body passageway attached to said body inlet port of said mid surface and said body outlet port of said top surface of said tapered end for communicating toothpaste from said toothpaste capsule to said internal passageway in said neck;
- said toothpaste capsule being of non-circular cross section and having an upper surface, a lower surface, and an interior volume for storing toothpaste;
- a capsule inlet port and a capsule outlet port on said upper surface, said outlet port inserts into said inlet port of said mid surface in said body;
- a rotating knob at said lower end of said capsule is fixed to a screw shaft in the center of said capsule, wherein rotation of said knob causes said screw shaft to rotate;
- a plunger member threadedly attached to said screw shaft, wherein rotation of said knob causes said plunger member to traverse said screw shaft and force toothpaste through said outlet port;
- said inlet port on said upper surface of said capsule having a threaded tapered interior for receiving a variety of different size toothpaste tubes, said threaded interior having a longitudinal slit through said threads to further accommodate multiple size toothpaste tubes, wherein toothpaste tubes transfer toothpaste into said capsule, and a tapered threaded cap seals said inlet port when said toothpaste tube is removed.
