  • the return release shuts off the dispensing of the paste and is clearly felt by the user, who realizes that it has dispensed a dose of paste.

Abstract

Une brosse, en particulier une brosse à dents, comporte un manche utilisé comme conteneur et distributeur à piston doté d'une vis d'alimentation le long d'une tige filetée (36); une surface à double came (30, 30', 33, 33') est conçue pour assurer une longueur d'alimentation régulière avec un retour rapide. Un panneau extensible (70) s'étend entre le piston et une partie fixe du cylindre de sorte que des caractères ou des dessins puissent lui être appliqués.
