  • 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.
