Abstract

See full text

A liquid purifying device for dispensing a liquid, including a container which has an interior space for storing a liquid, and a lid member for closing the interior space. The liquid is delivered out of the container, due to a pressure of a compressed air which is introduced into the interior space by air pumping means. The air pumping means includes a cylinder member which is reciprocated between an advanced position and a retracted position. The cylinder member is normally biased toward the advanced position, but may be held in the retracted position where appropriate. The lid member of the container has a liquid delivery path through which the liquid is delivered as desired, when a valve disposed in the path is placed in its open position upon pressing of a push-operated member. In the liquid delivery path, there is provided a filter adapted to remove bacteria from the liquid delivered through the path.
