Definitions

  • the toothbrush described herein relates to changeable or disposable brush heads and locking means for securing such brush heads to the toothbrush handle.
  • Teeth brushing has been improved on either in the formulation of toothpaste or the brush that is used. Some of these improvements are also expanded in scope to benefit the gum as well.
  • the present invention is a toothbrush contributing to improvements in teeth brushing which is an indispensable hygiene care. Its main feature is that it is a toothbrush with a detachable brush head. This allows the user to choose from a variety of pad design with different bristles configuration to suit the user's brushing needs. Besides the variety of brush head to choose from, the handle comes in different shapes that are ergonomically designed. This allows the user to mix and match the brush head with the handle not only to suit his or her brushing needs but also to have a toothbrush that is comfortable to use.
  • the brush head Since the brush head is interchangeable, only the brush head needs to be disposed off while the handle may be retained. This cuts down a high percentage of waste material contributed from thrown away toothbrush and makes this toothbrush environmental friendly.
  • the toothbrush is also simultaneously meant to be gum friendly since the bulk of its modular brush head is made of soft elastomeric material. It not only absorb the impact of the brush head knocking on to the gum but the back and the side of the brush head which is made of this soft yet elastic material can be used a gum massager, thus extending the function of this invention.
  • a brush head is not only securely held to its handle but it also securely locked in place through a locking means, which said locking means is preferably applied without need of tools.
  • said locking means allows the brush head to be removed easily from the handle at user's will but not when the toothbrush is in used.
  • the invention also allows permanent drawings to be imprinted, formed or molded onto the brush head as desired.
  • the locking means to lock the brush head to its handle can also be incorporated in electrical toothbrush after suitable modifications.
  • the invention is a toothbrush that is made up of a brush head engaged on to an elongated handle.
  • the modularity of the brush head and elongated handle allows the user to mix and match brush head from different bristle configurations and elongated handle from different handle design to suit individual brushing needs.
  • the brush head has a casing disposed on reverse side of bristles.
  • the casing is partially or fully elastic so that the handle head can be inserted entirely into the brush head.
  • the brush head may further include locking means using extended pins and corresponding holes which may have more than one embodiments. Since the casing is partially or fully elastic the toothbrush can be used as a gum massager. Worn out toothbrush can be disengaged for disposal which makes this invention environmental friendly.
  • the brush head may be incorporated into an electrical toothbrush. Brief Description of the Drawings

Abstract

L'invention concerne une brosse à dents (000) présentant une tête de brosse (200) qui peut être engagée sur et être désengagée d'un manche allongé (100) présentant un manche (102) au niveau d'une première extrémité (101) et une tête de manche (110) au niveau de la seconde extrémité. Cela est possible étant donné que la tête de brosse présente un logement totalement ou partiellement élastique (203) présentant un accès (210a), disposé au-dessus d'un tampon de soies (201), la tête de manche du manche allongé étant engagée dans la tête de brosse par insertion de la tête de manche dans le logement par l'intermédiaire dudit accès. La tête de brosse peut également comprendre un moyen de blocage (300) tel que des axes débordants (301, 401) et des trous (302, 402) correspondants. Ledit système peut être utilisé dans une brosse à dents électrique.
