Toothpaste

The first toothpaste was invented by a New London, CT dentist Washington Wentworth Sheffield. In the mid-1800's, he developed a cleaning powder that was quite popular with his patients. However, his toothpaste did not catch on until it was packaged in tin tubes. Interestingly, Dr. Sheffield received 30 patents ranging from a way of capping teeth to elevated railroads. The Sheffield Tube Company still exists today.

On our website, we stated that everything can be improved. Examine an improvement of toothpaste, US patent 6056466 titled "Toothbrush with a refillable toothpaste chamber".

The act of brushing one's teeth with a toothbrush is one commonly known to all and is necessary to maintain good dental hygiene. However, there is, and has been, many problems associated with brushing one's teeth using this arrangement. Perhaps the biggest of these problems is that it is necessary to always have both the toothbrush and the toothpaste in one's possession before beginning the act of brushing one's teeth. This may pose a problem especially during travel, where one may forget one or the other, or space may be at a premium with regards to bringing along personal care appliances.

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.
