Title
(EN) ORAL CARE IMPLEMENT AND METHOD OF MANUFACTURING AN ORAL CARE IMPLEMENT
(FR) INSTRUMENT DE SOINS BUCCAUX ET PROCEDE DE FABRICATION D'UN INSTRUMENT DE SOINS BUCCAUX
Abstract
(EN) A method of manufacturing an oral care implement comprising: (a) providing a body comprising a handle portion and a head portion, the head portion having a hole extending there through from a first side to a second side; (b) providing a layer of first material on the handle portion and the head portion to form a subassembly comprising a handle section, comprising the handle portion and a first portion of the layer of first material, and a head section, comprising the head portion and a second portion of the layer of first material; and (c) then injection molding a second material onto the head section to form one or more oral care elements of the second material on the head section and a member of the second material in the hole, which member is unitary with the one or more oral care elements.
(FR) L'invention concerne un procédé de fabrication d'un instrument de soins buccaux qui consiste à : (a) fournir un corps comprenant une partie manche et une partie tête, la partie tête comportant un trou s'étendant à travers celle-ci d'un premier côté à un deuxième côté ; (b) appliquer une couche d'un premier matériau sur la partie manche et la partie tête pour former un sous-ensemble comprenant une section de manche, y compris la partie manche et une première partie de la couche du premier matériau, et une section de tête comprenant la partie tête et une seconde partie de la couche du premier matériau ; et (c) mouler ensuite par injection un second matériau sur la section de tête pour former un ou plusieurs éléments de soins buccaux constitués du second matériau sur la section de tête, et un élément constitué du second matériau dans le trou, cet élément étant formé d'un seul tenant avec le(s) élément(s) de soins buccaux.
