CA 2426182

A dispenser (10) for dispensing a fluid includes a rigid vial (52) that has a main fluid chamber (55) containing a fluid, and a pump assembly (50) that is in fluid communication with the main fluid chamber (55) and is configured to dispense a predetermined quantity of fluid from the main fluid chamber (55). A flexible bladder (54) is provided which is located within the main fluid chamber (55) and is configured to expand to fill the ullage created within the main fluid chamber (55) during dispensing of fluid by the pump assembly (50). The resilient bladder (54) tends to force itself outwardly toward the rigid vial (52) and, in turn, increases the pressure within the main fluid chamber (55) in comparison to the interior of the bladder (54) to thereby prevent the ingress of air or vapors through the bladder (54) or otherwise into the main fluid chamber (55).

La présente invention concerne un distributeur destiné à distribuer un liquide, qui comprend un flacon rigide possédant une chambre à liquide principale contenant un liquide, et un ensemble pompe qui est en communication fluidique avec cette chambre à liquide principale et qui est agencé de façon à distribuer une quantité prédéterminée de liquide en provenance de la chambre à liquide principale. Une vessie souple située dans la chambre à liquide principale est agencée de façon à se dilater pour remplir le creux créé dans cette chambre à liquide principale pendant la distribution du liquide par l'ensemble pompe. La vessie souple à tendance à forcer vers l'extérieur en direction du flacon rigide et, à son tour, elle augmente la pression dans la chambre à liquide principale par rapport à l'intérieur de la vessie de façon à empêcher ainsi l'intrusion d'air ou de vapeurs dans cette vessie ou dans la chambre à liquide principale.
