The invention relates to an electric toothbrush () having a rechargeable energy store () that is arranged in an inner space () in the body () of the toothbrush (). The inner space () is sealed by a primary sealing element () against splash water and other detrimental influences. At least one contact element () for an external power supply unit () produces an electrically conductive connection to the energy store (). The contact element is located either within the inner space (), it being possible for the primary sealing element () to be removed for charging purposes, or outside the inner space (), in which case it is optionally protected by an additional secondary sealing element (). The invention also relates to a process for producing such a toothbrush.

Toothbrush and process for producing the same

A toothbrush has a toothbrush body, and a handle part wherein a toothpaste container can be removably inserted therein. The toothpaste container has a handle shell part which, with the toothpaste container inserted into the handle part, forms part of the outer surface of a handle. The toothpaste container essentially maintains its form during teeth cleaning and transmits loading which occurs, irrespective of the filling level of the toothpaste container of the toothbrush. The mounting of the toothpaste container on the toothbrush body allows very straightforward and quick removal and opening or insertion and closure of the toothpaste container. The container holder is provided with a closure pin, wherein when the toothpaste container is inserted into the handle part, a sealed closure of the toothpaste container is ensured. With the toothpaste container removed from the handle part, it is possible for toothpaste to be squeezed out of the toothpaste container.
