ABSTRACT:
A portable liquid purifying device for dispensing a liquid, which includes a squeezable bottle made of a soft material and containing a mass of the liquid, a filtering member removably engaging a bottleneck of the bottle, and a cover assembly for covering a spout formed through the filtering member so as to fluid-tightly close the spout. The filtering member has a first section which accommodates activated carbon, and a second section which accommodates a micro-porous membrane filter including hollow fibers, the first and second sections being disposed in series so that the liquid delivered out of the bottle passes through the first and second sections in this order. The filtering member is fluid-tightly and air-tightly attached to the bottleneck such that the filtering member does not protrude past the bottleneck. The cover assembly has a first position for fluid-tightly closing the spout, and a second position for opening the spout so as to permit the liquid to flow out of the device.
