are sealed using high-frequency adhesive. Next, as shown in Fig. 2, when the bag body 1 is pressurized or squeezed to push the air and unnecessary liquid inside the bag body 1 toward the check valve 2, the As shown in FIG. 2, the fluid is discharged through the gap 10, and the inside of the bag body 1 is brought into a near-vacuum state. Furthermore, once the air has been discharged, even if the outside air tries to flow into the interior due to the pressure difference, the blocking portion 7 of the valve body 6 prevents the outside air from flowing in, as shown in FIGS. As shown in b, the valve body 6
The opening 8 expands due to atmospheric pressure and closes the gap 10, thereby preventing inflow of discharged fluid and outside air. Furthermore, even if some of the outside air were to pass through the gap 10, the next valve body 6 would effectively prevent it from flowing into the interior.

出することができる。(Effects) Since the present invention has the above configuration, when unnecessary fluid in the bag body is moved to the check valve side, the fluid passes through the gap between the flow pipe and the valve body and reaches the outlet of the flow pipe. At this time, the open portion of the valve body is deflated by the flow pressure of the fluid from the closed portion, widening the gap and facilitating fluid discharge. Therefore,
Even after the stored items such as food are sealed, air and fluids such as unnecessary liquids can be discharged while maintaining the sealed state.
一方、流体を排出した後の袋本体の内部は真空
に近くなり、また、弁本体の閉塞部によつて外気
の流入が阻止されている関係で、弁体の開放部は
大気圧によつて拡開して間隙を塞ぎ、袋内への大
気の流入を確実に防止できる。 On the other hand, after the fluid is discharged, the inside of the bag body becomes close to vacuum, and since the inflow of outside air is blocked by the closed part of the valve body, the open part of the valve body is exposed to atmospheric pressure. It can be expanded to close the gap and reliably prevent air from entering the bag.
しかも、可撓性を有する袋本体を加圧、或は絞

きる。 Moreover, it is possible to create a vacuum inside the bag body by simple operations such as pressurizing or squeezing the flexible bag body, which has the economical advantage of not requiring the use of a vacuum device. The quality and taste of the stored items can be maintained well over a long period of time, and the shelf life can be significantly improved.
また、流体の排出は狭い間隙を通して行われる
ので、袋本体内の被収納物が不用意に飛び出すお
それもない。 Further, since the fluid is discharged through a narrow gap, there is no fear that the stored items in the bag body will accidentally jump out.
