<p>PROBLEM TO BE SOLVED: To provide a bag for freeze preservation from which the existing air in the bag in freezing it can be removed by a simple operation and the precious inside liquid can be completely discharged. SOLUTION: This bag for freeze preservation is provided with a seal part at the peripheral edge and at least two vertexes and further, it is provided with an outflow port 12 formed at the arbitrary vertex, a hanging hole 13 formed in the seal part 14 positioned at the opposite face of the outflow port 12, and an inflow port 11 formed at the other vertex. The inflow port and the outflow port are formed within the angular range of the opposite vertex angle of the interior angle of the vertexes in which these inflow and outflow ports are formed.</p> |
