parts

37 and 57 according to the rotation of the cover member 50.

At this time, the cover member 50 is hinged to the lifting member 30, the gasket 20 is mounted to the cover member 50 and the base member 10, the cover member 50 Is rotated to cover the upper surface of the base member 10, the gasket 20 is pressed at the same pressure in the front and rear.

If the cover member 50 is hinged to the base member 10, the rear of the gasket 20 adjacent to the center of rotation is pressed before the front, so that the front and rear of the gasket 20 The pressure applied can be different.

However, in the present invention, since the cover member 50 is hinged to the elevating member 30, when the cover member 50 is rotated, the front and rear of the gasket 20 is pressed at the same pressure. do.

To this end, in the state in which the cover member 50 covers the upper surface of the base member 10, the gasket 20 mounted on the lower surface of the cover member 50 and the upper surface of the base member 10 are mounted. The gaskets 20 are slightly spaced apart or weakly in contact with each other.

Thereafter, the vacuum pump 60 is operated.

Then, as the air inside the chamber 11 is discharged to the outside through the suction hole 12, the cover member 50 as shown in Figure 6a and 6b by the vacuum pressure inside the chamber (11) And the elevating member 30 is lowered together.

In this case, the user may press the cover member 50 slightly, so that the inside of the chamber 11 by the gasket 20 can be more closely maintained.

As the elevating member 30 and the cover member 50 descend, the gasket 20 and the elastic member 40 are compressed.

At this time, the cover member 50 is lowered simultaneously with the front and rear by the elevating member (30).

Therefore, the gasket 20 is compressed in the same way as the front and rear without variation, it is possible to prevent the portion of the gasket 20 is too pressed to reduce the sealing of the chamber (11).

On the other hand, the air inside the vacuum packaging paper 90 is moved to the chamber 11 through the heater 70 of the pressure rubber (80).

At this time, an embossing 81 is formed on the lower surface of the pressurized rubber 80, and the air inside the vacuum packing paper 90 is seen through the air passage formed by the embossing 81 to the chamber 11. Can be easily moved.

When the inside of the vacuum wrapping paper 90 is vacuumed, power is applied to the heater 70 to heat seal the opening of the vacuum wrapping paper 90.
