PROBLEM TO BE SOLVED: To provide a liquefied substance pack which is easy to unseal and can be safely unsealed since finger tips do not get contaminated when unsealing and a liquid does not splash or leak out. SOLUTION: A bag 1 comprises a pair of sheets 2 and 2 formed in an approximate square of a water-impermeable sheet material, whose outer rims are made into hermetic seals 3, 3, etc., by a thermally welding means. A part of the seal 3 is left not thermally welded to serve as a nozzle hole 4. The inside of the bag 1 is sectioned, by a partitions 5, into a liquid storage part 6 and a cushioning empty part 7 communicating with the nozzle hole 4. The empty part 7 communicates with the storage part 6 via a narrow passage 9 formed by passage-forming portions 8 between them and the partition 5, and a region of the passage 9 toward the storage part 6 is closed by an easy-to-peel part 10 which opens by a liquid pressure.
