<p>A dispenser (20) for fluids (19), preferably for fluids capable of releasing gas in solution at atmospheric pressure. The dispenser typically includes a container comprised of a housing (10) for a collapsible bag (18) containing the fluid (19) and wherein the application of manual force to the container (10, 60, 18) effects reducing of the volume of the container by an amount substantially the same as the volume of fluid dispensed. Release of the manual force after dispensing an amount of fluid results in the volume of the housing and the bag being restrained (14,15,14', 15') at a volume reduced by the volume of the amount of fluid dispensed.</p> |
