  • Publication number: 20110167579
    Abstract: The invention relates to a method and a device for producing a toothbrush or part thereof by the two-component or multi-component injection-molding process. To produce in the brush body segments that are isolated from the rest of the brush body, a mold which comprises three hollow regions is used. Two of these hollow regions that are separate from one another serve for producing the segments and the other regions of the toothbrush from a first component. A third hollow region serves for distributing material to the segments that are isolated from one another and from the other regions, or the corresponding hollow region. The material remaining behind there is removed and sent for disposal. In a further step, connecting elements between the segments and/or the other regions are injection-molded from a second component.

  • Publication number: 20110109149
    Abstract: The tips of pointed bristles are mechanically processed in order to remove any corroded threads or residual threads from the tip. Mechanically processed pointed bristles are fed to a receptacle recess of a tool in bundles, and aligned by means of a pin guided in the receptacle recess. The pointed bristles are pushed through the passage of the bristle carrier plate, and the end section are subsequently melted by means of a heating die in order to attach the pointed bristles to the bristle carrier plate. The mechanical processing of the tips of the bristles enables an error-free further processing of the pointed bristles utilizing the bristling method, particularly the AFT method.

  • Patent number: 7937794
    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: 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).

  • Publication number: 20100242194
    Abstract: An interdental treatment device, such as a toothbrush, includes a handle configured to accommodate an electric power source, a head carrying an interdental treatment tool, and a neck between the handle and the head. The head or neck includes a mechanical motorized vibratory device, including a drive which causes the head to vibrate. Electrical connections are operably connected to the mechanical vibratory device and the electric power source to power the mechanical vibratory device via the electrical connections. In various embodiments, a switch may be operably connected to at least one of the electrical connections to interrupt power from the power source to the mechanical motorized vibratory device. In various embodiments, a vibration-damping structure dampens vibration transmission from the head to the handle.

  • Publication number: 20100154152
    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.

  • Publication number: 20090183331
    Abstract: The toothbrush according to the invention is equipped with a handle of which the surface is formed, at least in certain sections, in a facet-like manner by way of multiplicity of planar surface-area elements. The surface-area elements are arranged directly adjacent to one another and form a network of element edges. The multiplicity of surface-area elements reproduce, more or less, an essentially rounded handle form, this ensuring comfortable use of the toothbrush in different rotary positions in relation to its longitudinal axis.
