  • Disposable toothbrush with a dose of toothpaste
    Patent number: 4844641
    Abstract: A disposable toothbrush comprises a toothbrush body having bristles, and a toothbrush back containing a dose of toothpaste. The toothpaste is isolated from the bristles by a protective film. A safety cap retains the toothbrush back separate from the toothbrugh body. Removal of the cap allows the back to approach the body, which causes tearing of the protective film and distribution of the toothpaste onto the bristles.
