ABSTRACT:
A flexible sealed bag for storing a liquid comprises a triangle-shaped flexible bag body which is tapered narrower toward its distal end and stores a liquid therein, and a wire for releasably fastening a portion near the distal end of the body, so as to separate the body into a liquid storing portion in which the liquid is sealed and a distal end portion in which the liquid is absent. An opening is formed in the distal end portion. Thereafter, the wire is removed and the liquid in the bag is discharged through the opening.
