Definitions

  • the invention relates to a toothbrush having a brush head consisting of a first plastic, on which a carrier body is arranged from a plastic that is softer than the first plastic. 2.

  • a plastic toothbrush of conventional construction has a plate-like brush head, which carries on its upper side a bristle stocking consisting of bristle bundles and / or individual bristles and is usually formed integrally with a handle-like extension which forms a handle.
  • the handle facing portion of the brush head consists of a first relatively rigid rigid plastic on which at the front, the handle facing away from the tip portion of a brush head portion of a Plastic deformation-softening 2.
  • Plastic is molded.
  • Bristle bundles and / or single bristles are mounted in both sections so that the user is preferably to use the bristles of the easily deformable softer tip section to clean the interdental spaces, and the bristles of the relatively rigid rear brush head section to clean the tooth surfaces.
  • this change between the use of different brush head sections when using the toothbrush is cumbersome and sometimes annoying for the user.
  • a toothbrush which has a brush head consisting of a relatively stable plastic 1, in which a circumferentially completely closed shell-like recess is formed.
  • a carrier body which consists of an elastically deformable material, carries a bristle facing, is inserted into the recess and engages over arranged on opposite sides webs in grooves of the brush head.
  • the carrier body In order to achieve a sufficient cleaning effect, the carrier body must be relatively large. If the carrier body has sufficient inherent rigidity, only a small proportion of the bristles abuts the teeth, as a result of which the cleaning effect is low and in particular limited to the cleaning of the tooth surfaces. If the carrier body to increase the cleaning effect and in particular for cleaning the interdental spaces is relatively soft and thus deformable, there is a risk that the carrier body is released from the recess.
  • the invention has for its object to provide a toothbrush of the type mentioned, with which it can be achieved both a gentle cleaning of the interdental spaces and an effective cleaning of the tooth surfaces in a simple manner.
  • a toothbrush with the features of claim 1. It is provided that in the existing of a first plastic brush head at least two circumferentially completely closed recesses are formed, in each of which a carrier body is arranged from a plastic with respect to the 1st softer softer 2nd plastic. At least up The carrier bodies, but preferably both on the carrier bodies and on the surrounding brush head, a bristle facing in the form of bristle bundles and / or individual bristles is arranged.
  • the arrangement of at least two recesses and correspondingly at least two support bodies, the deformation behavior of the toothbrush or the support body can be adjusted by choosing their geometry and their material in a very good manner and aligned with special cleaning effects.
  • the bristle bundles and / or individual bristles are subject to a different deformation behavior when using the toothbrush.
  • the carrier body deformed in the bristle facing away from the direction, whereby the attached to the carrier bristle bundles and / or individual bristles are withdrawn and preferred the further cleaning operation with the bristle bundles and single bristles mounted on the relatively rigid brush head without the toothbrush having to be used by the user for this purpose.
  • the deformation stiffness or softness of the carrier body results on the one hand from the carrier material forming the second plastic material and its material properties. In addition, determines the nature and geometry of the storage or attachment of the carrier body to the surrounding Brush head deforming when using the toothbrush.
  • the recesses formed in the brush head are completely closed in the circumferential direction, i. the recesses do not open to either side of the brush head and the inner wall of the recesses completely recirculates.
  • the carrier body is connected in connection portions with the surrounding inner wall of the recess. If the carrier body is connected over its entire outer circumference with the inner wall of the recess, the deformation stiffness of the carrier body is determined essentially by its material properties. In a preferred embodiment of the invention, however, it is provided that the connection between the carrier body and the surrounding inner wall of the recess comprises only a part of the outer circumference of the carrier body. The smaller the connecting surface between the carrier body and the inner wall of the recess, the greater is the deformation of the carrier body occurring during use of the toothbrush.
  • the carrier body is connected only on one side of its outer periphery with the surrounding inner wall of the recess.

  • a desired deformation behavior of the carrier body can be achieved in particular if the carrier body is attached to the inner wall of the recess via relatively small, precisely defined surfaces. This is for example given when the support body via connecting webs parallel to the deformation direction, i. the bristle longitudinal direction, or can also extend transversely to the deformation direction, is connected to the surrounding inner wall of the recess.
  • the carrier body is integrally connected to the inner wall of the recess. This is possible if the first plastic of the brush head and the second plastic of the carrier body enter into an intimate, sufficiently reliable connection.

  • Such a configuration has the advantage that when using the toothbrush and applying very low cleaning forces essentially only come on the carrier bodies arranged longer bristle bundles and / or individual bristles come into contact with the surfaces to be cleaned. If the user of the toothbrush applies a greater pressure force, the carrier body deform in the direction away from the bristle facing, whereby the arranged on the carrier bodies bristle bundles and / or single bristles are pressed into the bristle facing, so that in the further use the toothbrush and the arranged on the brush head bristle bundles and / or individual bristles come into contact with the surfaces to be cleaned.
