It can be in close contact with the surface 43 i of the air passage side of a. Therefore, no gap is generated between the flap 42 and the outer sheet 43a, and the airtight state inside the bag is kept good.
- the flap 42 is not limited to the shape described above, and can be implemented with various modifications.
- a flap in which the flap portion is formed only on one side of the fixing portion 42 a May be arranged as opposed to each other or in opposition to each other, and the number of flaps 42 in the air passage 41 may be arranged independently or in parallel. Is also good.
- the air passage 41 is usually provided with flaps 4 2 b and 42 c on both sides of the fixed portion 42 a. In both directions. Therefore, in order to allow the air passage 41 to be ventilated, the rod 5 should be connected between the inner opening 43c and the outer opening 43g of the air passage 41 as shown in FIG. This is performed by releasing the close contact between a part of the flap portions 42b and 42c and the surface 43i on the air passage side of the exterior sheet. As a result, the air passage 41 becomes permeable. Then, by pulling out the rod 5, the air passage 41 returns to the shut off state.
- This rod 5 is optimally implemented as a suction nozzle for a vacuum cleaner, or as a small pump with a built-in motor and fan, but it is a hollow straw-shaped one that is manually degassed. Is also good. Moreover, you may implement as a solid rod.

- the other upper end portion 61c of the flap sheet 61 is in a state in which the sheets 11, 12, and 61 are all adhered and completely closed. The air flow at the time of air flows only through the air passage 62.
- the deaeration port 7 is a portion of the bottom side 14 where the adhesion between the front sheet 11 and the back sheet 12 is interrupted, and the airflow from the deaeration valve 6 flows out of the bag through here.
- the deaeration valves 6 are provided at two places on the left and right, and the deaeration port 7 is provided at one place at the center, but the number of these installations is limited to this. Instead, they can be provided with appropriate changes.
- FIGS. 9 (B) and 9 (C) The vertical cross section of the degassing valve 6 is shown in FIGS. 9 (B) and 9 (C).
- the space between the flap sheets 61 is pushed and expanded according to the airflow, so that the air passage 62 is opened and air flows.
- the air that is going to flow into the bag is stopped at the closing portion 63, whereby the flap sheets 61 adhere to each other, so that the air passage 62 is closed and the air flows. Absent. Therefore, since only one-way airflow is allowed, the state in which the air in the degassing bag 1 is evacuated can be maintained.
- deaeration bag 1 When actually using the deaeration bag 1, after storing the items such as clothing inside, hold the deaeration bag 1 by hand, etc., to deaerate through the deaeration valve 6 and the deaeration port 7. Do . If necessary, deaeration can also be performed from the shutoff valve 4 by using a vacuum cleaner or the like, so that the deaeration work can be performed efficiently.
- valve illustrated here is only an example.
- a deaeration bag having a valve having various different structures, such as a valve having one flap sheet 61 and a separate check valve. It is also possible to attach a closing valve 4.
- valve includes a single flap sheet 61, a separate check valve, and, as shown in FIG.
- the valve seats 8 1, 8 2 are formed in a flat and substantially cylindrical shape between the front seat 11 and the back seat 12 of the above, and a flap 83 having the same structure as that shown in FIG.
- the closing valve 4 can be attached to a degassing bag having a valve of various different structures such as the provided valve 8. Since the present invention is configured and used as described above, it has the following useful effects.
- the adhesion between the air passage for deaeration and the bag main body is not easily detached without deteriorating the compactness of the deaeration bag, and the deaeration is maintained. It was possible to provide a deaeration bag capable of being used.
- the air passage is formed together with the rod-shaped body by a bag. This has the effect that it can be prevented from coming out.
