Oral care implement

An electrical appliance for personal care includes a handle with a longitudinal axis, and a plug-on part which can be attached to the handle, wherein a vibration unit having an electric motor and an eccentric element is arranged in the handle, wherein a plug-like coupling structure protrudes from the handle, which plug-like coupling structure forms an interface with a substantially mirror-inverted socket-like coupling structure of the plug-on part, wherein the interface has at least two stages with different circumferential geometry, wherein at least one of the stages has a rotation-preventing device between the handle and the plug-on part, and wherein a stop surface of the handle for the plug-on part extends obliquely with respect to the longitudinal axis of the handle.

Electrical appliance for personal care

An oral hygiene product, in particular a toothbrush, comprises at least one application unit and at least one handle unit, the at least one handle unit being formed partly from a soft component and partly from a hard component, wherein the soft component extends at least over a substantial part of a main extent of the at least one handle unit.

Oral hygiene product, in particular toothbrush

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.

A toothbrush including a main member that includes a handle portion, a neck portion and a head portion. At least one brush member, which forms at least part of the brush head along with the head portion and is movable relative to the head portion, is disposed in the head portion. The at least one brush member can be moved under the effect of a cleaning movement manually exerted on the teeth.

Toothbrush with moved elements

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.
