FLUID-FILLED BAG-SHAPED CONTAINER
Document Type and Number:
WIPO Patent Application WO/2022/202787
Kind Code:
A1
Abstract:
The present invention improves the freedom in design of a bag-shaped container having an injection hole for injecting a fluid. A bag-shaped container in which sheet-like container materials 3 having a fluid filling room 7 that maintains a shape by expanding when filled with a fluid are overlapped with each other, at least peripheral edge parts of the container materials 3 being bonded to each other to provide in the container a hollow portion 6 for accommodating contents. The bag-shaped container comprises: a partitioning/bonding part 10 that linearly bonds the overlapped container materials 3 together; a flap part 9 that is partitioned by the partitioning/bonding part 10 from a portion of the container materials 3 that serves as an outer wall part of the hollow part 6, the flap part 9 being provided apart from the portion serving as the outer wall part of the hollow part 6; an injection hole 11 that is formed in a portion of the container materials 3 that constitutes the flap part 9; and a path 12 that extends through the partitioning/bonding part 10, partitioning the flap part 9 and the fluid filling room 7, to permit communication between the injection hole 11 and the fluid filling room 7, the path 12 being air-tightly closed when the fluid filling room 7 is filled with the fluid.
