Claims

[Claims for Utility Model Registration] (1) A short cylindrical body 1 having an inner diameter larger than the outer diameter of a suction port of a vacuum cleaner, an elastic body 2 such as a spring, and a separate annular body 3. The short cylindrical body 1 has appropriate fixing means at appropriate positions on its outer circumferential surface, and forms a degassing opening by being attached to a degassing hole provided in a storage bag for a futon or the like. The short cylindrical body 1 includes a short tubular body 5 whose central axis is approximately the same, and the outer diameter of the short tubular body 5 is smaller than the inner diameter of the suction port of the vacuum cleaner. The space between the radially inner side of the periphery of the short cylindrical body 1 facing the inside of the storage bag and the radially outer side of the periphery of the short cylindrical body 5 facing the inside of the storage bag is sealed by a partition 6. The end of the short tubular body 5 facing the outside of the storage bag is sealed, and an appropriate number of holes 8 communicating with the inside of the short tubular body are provided at appropriate positions on the outer circumference of the short tubular body 5 near this end. Further, on the outer periphery of the short tubular body 5, a flange-shaped portion 7' is formed between the end portion and the hole 8,
The peripheral edge of this collar-shaped portion 7' is formed in a state of being folded back toward the partition wall, and the shape of the folded-back peripheral edge of the collar-shaped portion is smaller than the inner diameter of the suction port of the vacuum cleaner and the outer diameter of the short tubular body 5. On the other hand, the annular body 3 has an outer diameter that is approximately the same as the inner diameter of the short cylindrical body 1 and an inner diameter that is approximately the same as the outer diameter of the short cylindrical body 5; It is loosely fitted into the body of the tubular body 5 and is constantly biased against the periphery of the flanged body 7' by interposing the elastic body 2 between it and the partition wall, and comes into contact with the periphery of the flanged body 7'. A deaeration valve for a storage bag such as a futon, which is characterized by: (2) The end of the short tubular body 5 where the partition wall 6 is provided is sealed by a disk 12 having a diameter larger than the outer diameter of the short cylindrical body 1, and this disk is connected to the short tubular body 5. 2. The degassing valve for a futon storage bag according to claim 1, further comprising an appropriate number of ventilation passages 12' extending from the center to the periphery of the side surface.
