First, the sleeve 21 is pierced into the fitting edge 203 at the lower end of the sealing lid 20, then the tight packing 22 is sewn into the receiving tank 207 below the sealing lid 20, and the stopper 230 at the lower end of the air stopper 23 is further inserted into the concave tank. 200, the stopper 230 is stopped below the through hole 201, the air stopper 23 is covered with the air hole 202, and the horizontal holes 241 and 242 above the top lid 24 are straightened. 231 and 232 are penetrated, and the top lid 24 is welded to the concave tank 200 of the sealing lid 20 at a high frequency.

Thus, the assembly of the lid body 2 is completed. In addition, the washer 33 is covered in the lower end tank groove 322 of the tension rod 32, and then the tension rod 32 is bored upward from the passage 300 of the sleeve 30. Then, the sleeve 30 and the snap ring 31 are engaged with each other, the convex portion 302 at the lower end of the sleeve 30 is stopped in the recessed tank 310 inside the snap ring 31, and the upper end of the tension rod 32 and the push grip 34 are joined to each other. The assembly of the extraction cylinder 3 is completed when the convex ring 320 at the upper end of the rod 32 and the concave ring 340 at the lower end of the push grip are crossed.

When using, first put the food to be preserved in the can body 1, then cover the lid body 2 with the upper end of the can body 1, and further with a recessed fitting stopper at the lower end of the retaining ring 31 of the extraction cylinder 3. The portion 311 is received in the concave tank 200 above the sealing lid 20. A case where the tension rod 32 of the extraction cylinder 3 is pulled will be described with reference to FIG. By pulling the tension rod 32, the air flow direction inside the can body 1 rises from the can body 1 toward the air introduction port 210 at the bottom of the sleeve body 21 and then toward the pores 202 below the concave tank 200, so that the air plug 23 and It is discharged from the gap between the concave tanks 200. It is also drawn into the sleeve 30 through the lateral holes 241 and 242 at the upper end of the top cover 24. Simultaneously with the bleeding, the tension rod 32 is pulled simultaneously, and the washer 33 at the lower end of the tension rod 32 is housed in the tank end 322 by stopping at the blocking edge 301 at the upper end of the sleeve 30, and the washer 33 is firmly pushed into the pore 323.

A case where the tension rod 32 is pushed and the air is desired to be extracted will be described with reference to FIG. The washer 33 moves upward due to the lower pressure of the tension rod 32, and the gas in the sleeve 30 is extracted during the bleeding, and due to the pressure, it enters the gap between the sleeve 30 and the tension rod 32, and the tank groove It enters into the tension rod 32 via the advancing hole 323 of 322 and is discharged from the exhaust hole 321 at the upper end of the tension rod 32. Thus, the gas in the can body 1 is rapidly extracted to form a vacuum.

At this time, since the external pressure is not the same as the external pressure of the can body 1, the close packing 22 around the periphery of the sealing lid 20 and the upper end periphery of the can body 1 can be in close contact with each other, and the external gas cannot enter. Further, the air plug 23 tightly closes the pores 202 at the bottom of the concave tank 200 to shut off the gas in the outside world to provide a vacuum state and provide food that can be permanently stored. When it is desired to take out the food in the can, it will be described with reference to FIG. Even if the connecting rods 231 and 232 are slightly repelled toward the inside of the lateral holes 241 and 242 at the upper end of the top lid 24, a gap is created between the air plug 23 and the concave tank 200, and the outside air is exposed to the lateral holes 241 and 242. It enters into the pores 202 at the bottom of the concave tank 200 via 242 and further into the can 1 through the air inlet 210 at the bottom of the sleeve 21. At the same time, the pressure inside the can 1 and the outside world are balanced. The tight packing 22 no longer tightly fits the can body 1. Thus, the lid 2 can be easily opened to take out the stored material in the can.

[0013]
