に当接させた状態にして、吸引ポンプを作動させる。When, for example, rice is put into the vacuum storage bag constructed as described above and is vacuum-packed, rice is first put into the bag body 1 through the sealing chuck 1b (inlet / outlet) and then sealed, and then shown in FIG. In this state, the opening end 20a of the suction port 20 connected to the suction pump (not shown) is brought into contact with the upper surface of the non-permeable sheet 3 so as to surround all of the through hole 11 and the ventilation hole 3a inside. Then, the suction pump is operated.

する。When the negative pressure of the suction port 20 acts on the upper surface of the non-breathable sheet 3, the non-breathable sheet 3 is bent toward the suction port 20 as shown in the figure, and the air in the bag body 1 is discharged. Structure 1
The communication hole 13, the space 6, the through hole 11, and the ventilation hole 3a are sucked in this order, and the inside of the bag body 1 is evacuated (decompressed).
When the suction is stopped and the suction port 20 is released when the inside of the bag 1 has a sufficiently high vacuum, the air-impermeable sheet 3 is recessed in the outer sealing body 4 by the vacuum (decompression) action inside the bag 1. 1
2, the inside of the bag body 1 is completely sealed from the outside air by making the through hole 11 concavely curved inward.

ることはない。At the time of the suction operation as described above, powder such as bran contained in rice inside the bag is sucked out and adheres to the periphery of the outlet of the through hole 11 and the inner surface of the non-breathable sheet 3. When the accumulated amount increases, the adhesion of the air-impermeable sheet 3 is hindered, and the airtightness decreases. However, since the check valve structure 10 is provided with the space 6 in which the filter medium 7 is loaded, the powder is trapped by the filter medium 7 so as not to flow into the through-hole 11 or the non-permeable sheet 3. Therefore, as described above, the air-impermeable sheet 3 does not lower the airtightness due to the adhesion of the powder.

維持することができる。Further, even if the air-tightness of the non-breathable sheet 3 is reduced due to the adhesion of powder, the non-breathable sheet 3 has a simple structure placed on the outermost side. Because it is possible to easily remove the powder,
Hermetic performance can be easily restored. The outer sealing member 4 and the inner sealing member 5 have a detachable structure,
Can be easily attached / detached or disassembled, so that cleaning and replacement of the filter medium can be easily performed, and the airtightness of the air-impermeable sheet 3 can be maintained better for a long period of time. it can.
