A device for dispensing a liquid, including a container having an interior space accommodating the liquid, a first valve attached to the container, a delivery path having one end submerged in the liquid and extending through the container such that the other end is outside the container, and a second valve disposed in the delivery path for closing and opening the delivery path. The first valve permits a pressurized gas to flow therethrough into the container to raise the pressure within the container, but inhibits a discharge flow of the pressurized gas and the liquid therethrough out of the interior space. The liquid is delivered out of the container through the delivery path, due to the raised pressure within the interior space. The device has a micro-porous membrane filter disposed in a portion of the delivery path which is located upstream of the second valve, as viewed in the direction of delivery of the liquid. The micro-porous membrane filter removes microorganisms from the liquid delivered from the delivery path.

A liquid purifying device for dispensing a liquid, comprising: a container having an enclosed interior space in which a mass of said liquid is stored; first valve means, attached to said container, for permitting a supply flow of a pressurized gas therethrough into said interior space of the container to raise a pressure within said interior space, and for inhibiting a discharge flow of said pressurized gas and said liquid therethrough out of said interior space; a liquid delivery path having one end submerged in said mass of the liquid and extending through said container such that the other end is disposed outside said interior space, said liquid being delivered out of said interior space through said liquid delivery path, due to the pressure within said interior space which is raised by said pressurized fluid; second valve means, disposed in said liquid delivery path, for selectively closing and opening the liquid delivery path to prevent contamination by microorganisms of liquid which has been purified but not yet delivered; and means for filtering said liquid to remove microorganisms from the liquid delivered through said other end of said liquid delivery path consisting essentially of a micro-porous membrane disposed in a portion of said liquid delivery path which is upstream of said second valve means, as viewed in a direction in which said liquid is delivered out of said interior space, said micro-porous membrane filtering said liquid to remove microorganisms from the liquid delivered through said other end of said liquid delivery path.
