Abstract
A toothbrush with a refillable toothpaste chamber which provides for the storage of toothpaste of choice within the handle section is disclosed. The toothpaste tube mates with a matching threaded connection on the lower surface of the handle to allow filling of the present invention with no or minimal wasted toothpaste. When the conventional toothpaste tube is removed, a pressurizing pump is installed to allow the user to pressurize the toothpaste chamber. To dispense the toothpaste product, the user simply activates a valve to allow the flow of toothpaste up the handle of the toothbrush where it exits from within the brush assembly of the toothbrush. The toothpaste chamber holds a sufficient amount of toothpaste to allow for several tooth brushing cycles or for a period of use during short travel times. When the internal supply is depleted, the present invention is refilled by repeating the above process.
