Title
(EN) TOOTHBRUSH HAVING PRESSURE RELIEF UNIT AND METHOD OF PRODUCING THE SAME
(FR) BROSSE A DENTS COMPORTANT UN MECANISME DE DETENTE, ET PROCEDE DE PRODUCTION DE LA BROSSE A DENTS
Abstract
(EN)
Disclosed are a toothbrush and a method of producing the same. The toothbrush of the present invention includes a pressure relief unit (r) which is installed in a head part of the toothbrush and has a plate shape and a predetermined size sufficient to cover bristles set in the head part. In the present invention, the head part is thin, and the bristles are set in the head part without using a wire. Furthermore, the present invention is easily adapted for mass production using inexpensive equipment. As well, the pressure relief unit (r), which is installed in the head part, serves as a reinforcing unit. Therefore, the head part is prevented from breaking during use despite having a reduced thickness.
(FR)
L'invention concerne une brosse à dents et son procédé de production. La brosse à dents comprend un mécanisme de détente (r) installé dans une partie tête de la brosse et présente une forme plate et une taille préétablie suffisante pour couvrir l'ensemble poils ménagé dans la partie tête. Dans l'objet de l'invention, la partie tête est mince et les poils sont placés dans la partie tête sans utilisation de fil. De plus, l'objet de l'invention s'adapte facilement pour une production en série avec un équipement bon marché. De même, le mécanisme de détente (r) installé dans une partie tête de la brosse sert d'unité de renfort, ce qui empêche la partie tête de se casser pendant l'utilisation malgré son épaisseur réduite.
