초록 ▼

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.

A portable liquid purifying device for dispensing a liquid, comprising: a thin-walled squeezable bottle comprising soft material and having an interior space in which a mass of the liquid to be dispensed is stored, said bottle having (i) a bottleneck at one axial end thereof through which the liquid is dispensed, (ii) a substantially cylindrical shape with a bottom at the other axial end thereof, and (iii) a wall thickness small enough to allow said bottle to be folded or rolled when not in use; a filtering member removably engaging said bottleneck of said bottle, said filtering member comprising a first section containing activated carbon, and a second section containing a micro-porous membrane filter comprising hollow fibers, the micro-porous membrane filter comprising hydrophilic micro-porous hollow fibers and hydrophobic micro-porous hollow fibers or comprising micro-porous hollow fibers each having a hydrophilic portion and a hydrophobic portion, so that air can be discharged from the interior of the bottle through the hydrophobic hollow fibers or the hydrophobic portion when the bottle is squeezed, said first and second sections being disposed in series so that the liquid dispensed from said bottle passes through said first and second sections in this order, said filtering member further comprising a spout formed adjacent to said second section, said filtering member being fluid-tightly and air-tightly attached to said bottleneck such that said first section is located closer to said bottleneck than said second section and such that said filtering member does not protrude into said interior space past said bottleneck; and a cover assembly for covering said spout of said filtering member, said cover assembly comprising a first position for fluid-tightly closing said spout, and a second position for opening said spout so as to permit the liquid to be dispensed from the liquid purifying device.
