  • Patent number: 8534950
    Abstract: A toothbrush with an integral toothpaste dispenser has a handle portion and a toothbrush portion. A commercially available toothpaste tube is opened at one end and contained within a central aperture of the handle of the integral toothbrush. Toothpaste from the toothbrush tube is discharged into a channel contained within the toothbrush portion and exits between the toothbrush bristles through a non-return valve positioned close to a bristle exit aperture. Toothpaste is squeezed by upward movement of a pedestal supporting the toothpaste tube when the user turns a knob on the bottom of the handle. The toothpaste tube is supported by a vertical support tube within the central aperture of the handle, producing an accordion-like, uniform, progressive toothpaste tube collapse. The non-return valve is only open during toothpaste delivery and thereby prevents toothpaste spills. The close proximity between the toothpaste exit aperture and the non-return valve enables the toothpaste to remain moist between brushings.

  • Patent number: 8342767
    Abstract: A toothpaste dispensing toothbrush includes a handle, a brush head section, and a plunger assembly passed through a proximal opening of the handle and rotatably interfitted within a threaded axial bore. A body of toothpaste is attached to the plunger assembly wherein a leading portion of the toothpaste body is linearly ingressed into the brush head section when the plunger assembly is rotated along a first arcuate direction defined about a centrally oriented longitudinal axis of the threaded axial bore. In this manner, a trailing portion of the toothpaste body is retracted from the outlet and returned upstream along the brush head section when the plunger assembly is rotated along a second arcuate direction defined about the centrally oriented longitudinal axis. The first arcuate direction is opposite to the first arcuate direction so that the plunger assembly can be rotated in clockwise and counter directions respectively.
