Abstract

PURPOSE: To prolong the life of a filter for purification by providing the purifying vessel with a filter for purification at its bottom and providing the vessel with an inner vessel which has a communicating groove for allowing the pouring port of an outer vessel and the inside of the outer vessel to communicate with each other on the outside surface of its sidewall.
CONSTITUTION: The inner vessel 2 inserted with a purifying filter 15 is inserted into the outer vessel 1 from the aperture 6 of the outer vessel 1. The inner vessel 2 closes the aperture 6 of the outer vessel 1 and is detained by a detaining part 12 to the peripheral edge of the aperture 6 and is positioned to the upper half part in the outer vessel 1. At the time of purifying the potable water, the water is first poured from the aperture 11 of the inner vessel 2. The water poured into the inner vessel 2 is purified by the purifying filter 15 and is dropped into the inside of the lower half part of the outer vessel 1 where the water is stored. The purified potable water stored in the lower half part of the outer vessel 1 may be poured from the pouring port 7 when a user grips the handle part 8 and tilts the purifying vessel A.
