Claims

[Claims for Utility Model Registration] (1) A toothbrush consisting of a brush part with brush bristles implanted on the outside, and a handle part connected to the brush part, wherein at least the brush part of the brush part and the handle part is a cavity provided inside for sealing toothpaste; a plurality of delivery holes communicating between the cavity and the outside on the brush part; and a plurality of delivery holes for delivering the toothpaste sealed in the cavity. A toothbrush equipped with a toothpaste extrusion mechanism that pushes toothpaste out from the hole, and. (2) The toothbrush according to claim 1, further comprising a stopper that is removably provided at the end of the dispensing hole and that closes the dispensing hole when mounted in a predetermined position. (3) The cavity is provided to communicate with the inside of the brush part and the handle, and the toothpaste pushing mechanism is formed by making the cavity in the handle have a constant cross-sectional shape. a cylinder part; a piston fitted into the cylinder part and capable of reciprocating within the cylinder; and a push rod having one end protruding outside the handle part and causing the piston to reciprocate within the cylinder part. 3. The toothbrush according to claim 1, wherein the toothbrush has a configuration in which the toothpaste inside the cavity is delivered to the outside by pushing the push rod toward the brush portion. (4) The hollow portion is provided to communicate with the inside of the brush portion and the handle, and the toothpaste pushing mechanism is formed by making the hollow portion in the handle have a constant cross-sectional shape. a cylinder part; a piston fitted into the cylinder part and capable of reciprocating within the cylinder; the piston being screwed into a threaded hole provided in the piston and provided in the cylinder part, one end of which is connected to the handle part; a feed screw fixed to a rotary knob provided externally on the rotary knob; when the rotary knob is turned, the piston provided on the feed screw is displaced toward the brush portion, and the hollow 3. The toothbrush according to claim 1, wherein the toothbrush is configured to discharge toothpaste inside the toothbrush to the outside.
