Patent

CA 2679441

A fluid dispenser (10) is provided that includes a multiple chamber fluid storage region (21, 23), each having a dispensing pump (26, 27) of its own such that the dispenser (10) can dispense the fluids (22, 24) from within the multiple fluid storage regions (21, 23). Further, the multiple fluid storage regions (21, 23) may each contain the same or different liquids (22, 24). The dispensing pumps (26, 27) include a metering housing (32), which when depressed, generate a one-way flow from the interior fluid storage region (21, 23) of the container that serves to fill the predetermined volume of the chamber within the metering housing (32). When the metering housing (32) is depressed a second time a substantially equal volume of each of the fluids (22, 24) is dispensed from the container, while upon release, the metering housings (32) are refilled by drawing fluids (22, 24).

L'invention concerne un distributeur de fluide (10) comprenant une zone de stockage de fluide à chambres multiples (21, 23), chaque chambre étant pourvue de sa propre pompe de distribution (26, 27), de sorte que le distributeur (10) puisse distribuer les fluides (22, 24) contenus dans les zones de stockage multiples (21, 23). Ces zones multiples (21, 23) peuvent également contenir chacune les mêmes liquides ou des liquides différents (22, 24). Les pompes de distribution (26, 27) comprennent un logement de dosage (32) qui, lorsqu'il est enfoncé, génère un flux à sens unique provenant de l'intérieur de la zone de stockage de fluide (21, 23) du contenant qui sert à remplir le volume prédéterminé de la chambre à l'intérieur du logement de dosage (32). Lorsque ce dernier (32) est enfoncé une deuxième fois, un volume sensiblement égal de chaque fluide (22, 24) est distribué à partir du contenant. Lorsqu'il est relâché, les logements de dosage (32) sont remplis à nouveau par aspiration des fluides (22, 24).
