Abstract

Une tête interchangeable (4) d'une brosse à dents présente un porte-soies (5), au moyen duquel elle peut coulisser sur la partie avant (3) d'un manche (2). Les deux parties (3, 5) de la brosse peuvent être assemblées mutuellement par l'intermédiaire de guides latéraux (34, 35) s'étendant dans le sens longitudinal de la brosse et de rainures longitudinales complémentaires (14, 15), et peuvent être fixées, dans le sens longitudinal, en position finale, par l'intermédiaire d'éléments d'encliquetage élastiques (37, 38). Aux deux parties (3, 5) de la brosse sont associés des éléments de centrage (22, 42) qui s'emmanchent lorsque les deux parties précitées (3, 5) sont assemblées, améliorant ainsi la tenue de la tête (4) de la brosse sur le manche (2) lors du brossage des dents.
