    (54) Air-exaustible bag for storing articles


    (57) An air-exhaustible bag for storing articles therein at vacuum, which has an improved closure to close an opening smoothly and hermetically, is provided. The air-exhaustible bag comprises a bag body, an opening (4) being defined by the first and second walls (2a,2b) on a side of the bag body, an air exhaust port (6) being defined on either one of the first and second walls (2a,2b). The first and second walls (2a,2b) are made of a material which can inherently be sealed to itself merely by contact and separated from each other without adversely affecting each surface thereof. Whereby the opening (4) can hermetically and separably be closed.
