The brush head of the toothbrush has filaments that are pointed at one end and led through clearances in the bristle carrier. These filaments have a length of about 10-20 mm. The tips of the pointed filaments produce a height profile other than that of a plane and the ends of the pointed filaments that are remote from the tips are melted.

Brush head for a toothbrush and method for producing the brush head

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 through 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.

Brush, in particular toothbrush, and associated production method

The toothbrush has a handle, a neck and a head. In the handle there is a first hard component which has a metallic covering. At least in regions, the metallic covering has a covering of a second hard component.

Toothbrush with partially coated surface

A toothbrush, comprising a head part with a cleaning structure that comprises bristles, a hand part and a neck part, a cavity comprising 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 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.

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.

Oral hygiene device, particularly a toothbrush, and method for the production thereof

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.

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.

Toothbrush with faceted handle

A brush, in particular a toothbrush, including a head part with a cleaning structure with bristles, a handle 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. The cavity may be 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.

A brush head and a toothbrush having a brush head with inclined and tapered bristles. In one aspect, the toothbrush includes a grip part, a head part, and a bristle area with tufts of bristles that are inserted therein. At least one of said tufts of bristles is inclined. The brush head is characterized in that the bristles in the at least one inclined tufts of bristles is tapered.
