  • Method for producing toothbrushes bristled in an anchorless manner
    Patent number: 8534769
    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.

  • BRUSH, IN PARTICULAR TOOTHBRUSH, AND ASSOCIATED PRODUCTION METHOD
    Publication number: 20130212823
    Abstract: A brush, in particular a toothbrush, comprising a head part with a cleaning structure featuring bristles, a hand part and a neck part, and a cavity located in the head or neck part comprising at least one outlet opening for an active substance. In one embodiment, the cavity incorporates an active substance element, which contains 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 the brush is easy to use.

  • TOOTHBRUSH HAVING A BRISTLE AREA DESIGN
    Publication number: 20130139338
    Abstract: A process for producing toothbrushes covered with bristles in an anchor-free manner, in which a tuft of bristles with cylindrical bristles and/or pointed bristles is introduced into a receiving recess of a mold of a bristle-providing machine and, by means of a profiled pin guided in the receiving recess, force is applied to the end facing the pin of the bristles of the tuft of bristles for the alignment thereof, so that the bristles of the tuft of bristles are aligned by means of an end face of the profiled pin and, as a result, form the topography that complements the topography of the end face of the profiled pin, wherein the profiled pin has on the end face that acts on the bristles a discontinuous surface, which forms multiple levels. This achieves a bristle area configuration that has multiple areas of use. A correspondingly produced toothbrush is also described.

  • Toothbrush with faceted handle
    Patent number: 8448284
    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.

  • METHOD FOR PRODUCING A TOOTHBRUSH AND TOOTHBRUSH
    Publication number: 20120284945
    Abstract: In the production of toothbrushes, the neck part and the head part are bent relative to each other from the original shape thereof by a predetermined angle (?) in the hot state of the toothbrush body. Thereafter, the force applied to the toothbrush body by the stretching device in order to bend the toothbrush body is removed so that the toothbrush body can bend back into the original shape thereof. The risk of fractures, in particular brittle fractures, can be greatly reduced by said action. The method is advantageous, in particular, if the toothbrush body was heated during processing by ultrasonic welding.

  • ORAL HYGIENE DEVICE, PARTICULARLY A TOOTHBRUSH, AND METHOD FOR THE PRODUCTION THEREOF
    Publication number: 20120284944
    Abstract: The oral hygiene device, particularly a toothbrush, has in the neck part, a cavity, which is closed off from the surroundings and in which a snap dome is arranged. This snap dome produces an acoustic warning signal when a limiting bending of the neck part is exceeded as a result of a limiting pressing force with which the head part is pressed, for example, against the teeth and gums is exceeded. On the one hand, this has the effect of protecting the snap dome, usually produced from metal, from corrosion and, on the other hand, the cavity serves as a resonance chamber to amplify the warning signal.
