摘要:
The invention relates to an electric toothbrush (10) having a rechargeable energy store (24) that is arranged in an inner space (36) in the body (12) of the toothbrush (10). The inner space (36) is sealed by a primary sealing element (56) against splash water and other detrimental influences. At least one contact element (28) for an external power supply unit (46) produces an electrically conductive connection to the energy store (24). The contact element is located either within the inner space (36), it being possible for the primary sealing element (56) to be removed for charging purposes, or outside the inner space (36), in which case it is optionally protected by an additional secondary sealing element (76). The invention also relates to a process for producing such a toothbrush.

The wire of the interdental treatment part is inserted into a shaft opening of the injection molding tool, preferably into a strip of the injecting molding tool such that said treatment part projects with a mounting section thereof into a cavity connected to the shaft opening. Preferably, a first cavity section is configured is configured on the strip, and a second cavity section is configured on a cavity body, to with the strip abuts at least during the injection molding process. After injection of plastic into the cavity, and after the at least partial curing thereof, the handle part thus formed is moved by a distance in the direction against the cavity along with the interdental treatment part, and the handle part is removed from the opened injection molding tool.

The invention relates to saucer-type handle components (5, 6) that pertain to a hollow handle and are produced in several steps. Said handle is used for a toothbrush. Said components are joined together and are inserted into an injection mould (25). A synthetic material, preferably a thermoplastic elastomer, is injection-moulded around the mould-parting line between the handle components (5, 6) in said injection mould (25). The connection seam (22) thus produced holds the two handle components (5, 6) together in a nondetachable manner and seals the hollow space (13) which is formed by the handle components (5, 6).

According to the present invention, a razor handle includes a connecting pod and a first handle portion. The connecting pod has a cartridge-connecting member, and a handle-connecting member. The first handle portion includes a pod-connecting member, and includes a first molded portion, a battery-powered device, and a second molded portion. The battery-powered device is at least partially encased between the first molded portion and the second molded portion. The handle-connecting member of the connecting pod is connected to the pod-connecting member of the first handle portion such that the connecting pod and the first handle portion are not detachable during normal use of the razor handle. The cartridge-connecting member of the connecting pod is operable to connect to a selectively detachable razor cartridge.
