Title
(EN) PUMP DISPENSER
(FR) DISTRIBUTEUR A POMPE
Abstract
(EN)
A pump dispenser is described for dispensing a product through a pumping mechanism that draws product from a storage container upwards through a dip tube (12), across a check valve (56), into a collecting chamber (14) from which it is dispensed through a one-way monitoring valve and exits a nozzle (20). Flow is initiated by compression of a domed elastomeric wall (18) covering the collecting chamber. A vent system of conduits including a conical ring valve brings air into the container to equalize pressure upon release of compression against the elastomeric wall. The one-way monitoring valve, downstream from the collecting chamber, may be formed as a duckbill valve of elastomeric rubber having an exit slit at the dispensing end. This slit, normally closed, will open upon pressure from a product flow. Excellent control of dispensing amounts is achieved through the pumping mechanism.

L'invention concerne un distributeur à pompe pour distribuer un produit à l'aide d'un mécanisme de pompage. Celui-ci attire le produit vers le haut, depuis un récipient de stockage, pour le faire passer à travers un tube plongeur (12) et une vanne d'arrêt (56), puis dans une chambre de collecte (14) à partir d'où il est distribué par une vanne de contrôle de non retour, avant de sortir par une buse (20). L'écoulement est initié par la compression d'une paroi élastomère en dôme (18) recouvrant la chambre de collecte. Un système d'évent de conduits comprenant une vanne annulaire conique alimente le récipient en air, ce qui permet d'égaliser la pression lors du relâchement de la compression contre la paroi élastomère. La vanne de contrôle de non retour, en aval de la chambre de collecte, peut avoir la forme d'une vanne en bec de canard, en caoutchouc élastomère, comportant une fente de sortie au niveau de l'extrémité de distribution. Cette fente, normalement fermée, s'ouvre sous l'action de la pression appliquée par l'écoulement d'un produit. On obtient ainsi un excellent contrôle des quantités distribuées par le mécanisme de pompage.
