Title
(EN) SYSTEM FOR CLOSING A DEVICE FOR THE LOW-PRESSURE DISPENSING OF A PASTY LIQUID MATERIAL
(FR) Système de fermeture d'un dispositif de distribution à basse pression d'un produit liquide à pâteux
Abstract
(EN)
The invention relates to a device (1) for dispensing a pasty liquid material (2) by means of a low-pressure manual metering pump (5), which is provided with an system for closing an end (32), and which is intended for a rigid or flexible container (4), the operation of said pump being ensured by: a lower check valve (11) and a metering chamber (10) which consists of a resiliently deformable bellows (9) and which is in communication with an upper valve (14) consisting of, in series: a stopper (16) for the channel (13) of the spout (8), which ensures that the end (32) is closed; a resiliently deformable diaphragm (15) enabling the stopper (16) to be opened; an auxiliary return member (17) suitable for the low pressures causing the closing of the stopper (16); and a sealed vessel (18), characterized in that the resiliently deformable diaphragm (15) is combined with the vessel (18) that said diaphragm seals, wherein the auxiliary return member (17) is arranged inside said vessel so as to be permanently linked to the diaphragm (15), and said vessel includes two levels (19, 20) that are resiliently deformable according to various characteristics.
(FR)
Dispositif de distribution (1) d'un produit liquide à pâteux (2) par une pompe manuelle de dosage (5) à basse pression et munie d'un système de fermeture d'extrémité (32), destiné à un contenant rigide ou souple (4), le fonctionnement de ladite pompe étant assuré par un clapet bas anti-retour (11), une chambre de dosage (10), composée par le soufflet (9) élastiquement déformable, communiquant avec un clapet haut (14) constitué consécutivement par : un obturateur (16) du conduit (13) du bec (8) assurant la fermeture d'extrémité (32); une membrane (15) élastiquement déformable permettant d'ouvrir l'obturateur 16; un organe de rappel auxiliaire (17) adapté aux basses pressions sollicitant la fermeture de l'obturateur (16) et une cuve hermétique (18), caractérisé en ce que la membrane élastiquement déformable (15) est associée à la cuve (18) qu'elle ferme hermétiquement, et à l'intérieur de laquelle est disposé l'organe de rappel auxiliaire (17), en liaison permanente avec la membrane (15) et comprenant deux étages (19,20) déformables élastiquement selon des caractéristiques différentes.
