Zusammenfassung:To provide a liquid storage bag which can be evenly inflated without breakage from a folded state where it is stored in an exterior container.SOLUTION: A liquid storage bag 30 of the invention includes: a spout 31 into which a liquid extraction tube 20 is removably inserted; and a bag body 32 having a storage space inside. The bag body 32 comprises: a first sheet portion 33 joined to the spout 31; a second sheet portion 34; and a seal portion 35 joining the peripheral edge portions of the first sheet portion 33 and the second sheet portion 34 together. In the folded state in which a bag 32 is folded so that the second sheet portion 34 covers the one end 20a side of the liquid extraction tube 20 along the one end 20a side of the liquid extraction tube 20, contained in the accommodation space, and the first sheet portion 33 is closer to the one end 20a side of the liquid extraction tube 20, the seal portion 35 is located between the first sheet portion 33 at the outermost circumference and the second sheet portion 34 at the portion covering the one end 20a side of the liquid extraction tube 20.SELECTED DRAWING: Figure 1 【課題】外装容器に収容された畳み込み状態から、破損を抑制しつつ満遍なく膨らませることが可能な液体収容袋を提供する。【解決手段】液体収容袋30は、液体取出管20が挿抜可能に挿入されるスパウト31と、収容空間を内部に有する袋体32とを備える。袋体32は、スパウト31に接合された第1シート部33と、第2シート部34と、第1シート部33および第2シート部34の周縁部同士を接合するシール部35とを含む。収容空間に収容された液体取出管20の一端20a側に沿うように当該液体取出管20の一端20a側を第2シート部34が覆い、かつ、第1シート部33が液体取出管20の一端20a側に近づくように袋体32が畳み込まれた畳み込み状態において、シール部35は、最外周に位置する部分の第1シート部33と液体取出管20の一端20a側を覆う部分の第2シート部34との間に位置する。【選択図】図1
