Definitions

  • the invention relates to a toothbrush head and a toothbrush with such a toothbrush head according to the preambles of claims 1 and 20, respectively.
  • Toothbrushes are well-known items for dental care, tongue cleaning and general oral hygiene. Toothbrushes typically include a handle, a neck, and a flattened toothbrush head that is studded with bristles. They are often made from one or more plastic components.
  • a toothbrush is in the WO 96/02165 described.
  • notches run on the bristle-tipped top and opposite bottom of the toothbrush head, forming flexible joints.
  • the flexible joints divide the toothbrush head into a number of head segments, which can be flexibly deflected or bent against each other. Due to the deflectability, the toothbrush head can adapt to the outer contours to be cleaned in the oral cavity.
  • the document EP 0 930 A2 discloses a flexible brush head for a toothbrush with a bristle carrier, which consists of a first, hard, elastic plastic and is divided by transverse to the longitudinal axis of the brush head tunnel in the longitudinal direction of the brush head successively arranged segments.
  • the segments of the bristle carrier and the tunnels preferably extend over the entire width of the brush head.
  • the tunnels are filled with a second, soft, elastic plastic and connected to one another via a groove provided laterally on the bristle carrier.
  • the areas of the bristle carrier that define the tunnels on the bristle-carrying side of the brush head and on the opposite side from the latter are elastically deformable and act as a bending limit in a deflection of the bristle carrier segments during use.
  • the areas which cover the tunnels on the bristle-carrying side can be subdivided into two sections by a dividing plane extending over the entire width of the brush head, which sections normally touch one another in the normal state.
  • Object of the present invention is to provide a toothbrush head or a toothbrush with flexibly deflectable head segments, the or has a long life and prevents bruising of tissue of the oral cavity.

In this way, the life of the toothbrush head or a toothbrush equipped therewith is prolonged and breakage of the toothbrush head is avoided. Due to the narrowing of the material recesses at the same time penetration or clamping of tissues of the oral cavity, such as the tongue, in the Materialausappel adopted by the at the Ausappelungs109 shaped limiting elements difficult or prevented.
