<p>The tooth brush with automatic dispensation of toothpaste has a handle (1) consisting of a container for the toothpaste. The container has a partly flexible wall to press out the toothpaste. A brush carrier head (3) is releasably mounted on the handle and there are channel devices to pass the toothpaste from the handle to the brushes (5). Cap- or sheathing devices (5) protect the brushes and there are means to prevent the passage of toothpaste to the brushes when the brush is not in use. At its opposite ends, the container h as devices (7, 8) for connecting with an extended safety cap. This has a twin function in that it protects the head (3) when the brush is not in use and it also extends the handle, which is formed from the container itself.</p> |
