  • Patent number: 8109686
    Abstract: A brush, in particular a toothbrush, including a head part with a cleaning structure that with bristles, a hand part and a neck part, a cavity with at least one outlet opening for an active substance being located in the head or neck part. In one embodiment, the cavity incorporates an active substance element, which contains the active substance in a carrier material and releases the substance in a controlled manner when it comes into contact with water. In another embodiment, the cavity is adapted to the shape of an active substance element by means of defined external contours. The volume of the cavity is preferably 1-2 times and no more than 4 times greater than the volume of the active substance element, ensuring that the latter is preferably surrounded by water during use. This allows the active substance to be effectively metered and ensures that the brush is easy to use.

  • Patent number: 8089227
    Abstract: A toothbrush has a removable end cap at its free end area directed away from the bristles, which end cap closes off an inner space of a grip element. The end cap accommodates an electrical control element, in particular a potentiometer, which can be adjusted via an adjustment element arranged rotatably on the end cap. The toothbrush also comprises an electrical power consumption unit, in particular an electric motor, which is designed to set the bristles in vibration. The energy supply from an energy reservoir arranged in the interior to the electrical power consumption unit can be adjusted continuously by means of the control element, as a result of which the vibration intensity of the bristles can be steplessly adjusted.

  • Patent number: 8083980
    Abstract: A unitary two component article for personal hygiene, such as a toothbrush, wherein the same is formed by injection molding of two differing plastic materials. The plastics do not adhesively or chemically bond to each other. The two differing plastic parts of the toothbrush are mechanically connected, such as by interfitting portions of the two plastic components or by shrinking one plastic component about the other.

  • Patent number: 8051520
    Abstract: 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.

  • Patent number: 7921499
    Abstract: The invention relates to a method and a device for producing a toothbrush (50) or part thereof by the two-component or multi-component injection-molding process. To produce in the brush body segments (20) that are isolated from the rest of the brush body, a mold (10) which comprises three hollow regions (12, 14, 16) is used. Two of these hollow regions (12, 14) that are separate from one another serve for producing the segments (12) and the other regions (18) of the toothbrush (50) from a first component (38). A third hollow region (16) serves for distributing material to the segments (20) that are isolated from one another and from the other regions (18), or the corresponding hollow region (14). The material (22) remaining behind there is removed and sent for disposal. In a further step, connecting elements (42) between the segments (20) and/or the other regions (18) are injection-molded from a second component (39).
