Title (EN) CARTRIDGE SYSTEM FOR DISPENSING PREDETERMINED RATIOS OF SEMI-LIQUID MATERIALS
(FR) SYSTEME DE CARTOUCHE DE DISTRIBUTION DE PROPORTIONS PREDETERMINEES DE MATIERES SEMI-LIQUIDES
Abstract:
(EN) The present invention relates to a system for dispensing semi-liquid materials simultaneously and in a predetermined ratio while preventing hazardous leakage to the environment. The present invention overcomes the disadvantages of conventional devices by providing a system which includes two cartridges (14, 16) having the same or selected different diameters, the cartridges being rigidly snapped together by interfitting male and female elements (60, 62, 68, 70, 72, 74). A seal (38) is also provided for each of the cartridges which includes a resilient wiping lip (48) formed around the outer periphery of the seal. Venting grooves are also provided in the inner wall of the cartridge so that air may readily be expelled from the cartridge as the seal is inserted.
(FR) Système de distribution de matières semi-liquides simultanément et en une proportion prédéterminée, empêchant les fuites dangereuses dans l'environnement. L'invention résout les inconvénients de dispositifs classiques à l'aide d'un système comprenant deux cartouches (14, 16) ayant des diamètres identiques ou différents sélectionnés, lesdites cartouches étant emboîtées rigidement ensemble par des éléments d'emboîtement mâle et femelle (60, 62, 68, 70, 72, 74). Chacune des cartouches dispose d'un joint d'étanchéité (38), lequel comprend une lèvre (48) d'essuyage résiliente, formée autour de la périphérie extérieure dudit joint d'étanchéité. On a également prévu des gorges de passage d'air dans la paroi intérieure de la cartouche, de sorte que de l'air peut facilement être expulsé de ladite cartouche à mesure que l'on insère ledit joint d'étanchéité.
