物の取出しが容易になる。 Vacuum packaging function Switch the base end of the hose 31 to the intake port 63. The nozzle 3 is inserted into the opening 91 of the tree sheet bag 9 containing food, and the lid 2 is closed to such an extent that the pressing surface 21 of the lid 2 lightly touches the bag 9. After pressing the bellows body 41 of the hand pump 4 with your hand,
Release pressure. When the bellows body 41 returns to its original shape by the force of the spring 44, the air in the bag flows through the nozzle 3 and the hose 3.
1. It flows into the bellows body 41 through the check valve 61. When the bellows body 41 is pressed again, the air in the bellows body 41 passes through the check valve 62 and flows out from the exhaust port 64. When the pressure is released, the bellows body 41 is released as described above.
The inside becomes negative pressure and the air inside the bag is sucked out. By doing this several times, the inside of the bag becomes a vacuum state, and when the bag comes into close contact with the food inside, the heater 51 is activated and the lid 2 is strongly pushed downward to create a space between the pressing surface 21 of the lid 2 and the hot plate 5. Pinch the open end of the bag. This heat-seals the opening of the bag. When the lid body 2 is opened, the bag can be pulled out. Bag inflation function Switch the tip of the hose 31 to the exhaust port 64 as shown by the two-dot chain line in FIG. Open the vacuum package 9 and insert the nozzle 3 into the opening 91.
is inserted, and the lid 2 is closed to such an extent that the pressing surface 21 of the lid 2 lightly touches the bag 9. When the bellows body 41 of the hand pump 4 is pressed by hand,
The air in the pump 4 is forced into the bag from the exhaust port 64 through the hose 31 and the nozzle 3. When the pressure on the pump is released, the bellows body 41 returns and the intake port 63 is introduced into the pump. After performing the above operation once or twice, the bag will expand, making it easier to take out the contents.
