  • Patent number: 9968427
    Abstract: The transmission according to the invention for an electric toothbrush serves for the transmission and reforming of a rotational movement provided by an electric motor into a particularly careful and effective cleaning movement of a cleaning element. The ratio of the distance between the longitudinal mid-axis of an output shaft and the longitudinal mid-axis of a drive shaft of the transmission and of the distance between the longitudinal mid-axis of a shaft driving a cam of the transmission and the longitudinal mid-axis of the cam amounts to at least 10:1.

  • Publication number: 20170318947
    Abstract: A toothbrush having a brush body and a bristle carrier that is produced from a hard material using an injection molding method and having injection-molded bristles that protrude from the bristle carrier. The injection molded bristles are produced from a bristle material using the injection molding method. The bristles have a bristle stem and the bristle carrier has a small carrier plate or is formed by the small carrier plate that is produced from a hard material using the injection molding method and fastened on the brush body. The hard material of the bristle carrier or the hard material of the small carrier plate is harder than the bristle material.

  • Publication number: 20170079420
    Abstract: A brush, particularly a toothbrush, includes a head part with a cleaning structure that includes bristles, a hand part and a neck part, a cavity including 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, containing the active substance in a carrier material and releases said 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: 9526595
    Abstract: 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.
