作業に支障を来す等の欠点があつた。(Prior Art) A conventional method for manufacturing a gas-filling can is as disclosed in US Pat. No. 2,629,421, for example.
A flange mold is used on both ends of the cylindrical can body to form a flange with uneven parts for deaeration and gas filling, and a flat flange with no uneven parts on the other side. Place the can body on the lifter plate with the shaped flange side facing up, place either the lid (bottom lid) or the canopy on the planar flange, and then lift the lifter plate. With the lid raised and the flange pressed against the head (receiver) of the seaming machine, the lid and flange are seamed using a seaming roller, and after the seaming is completed, the lifter plate is tightened. After the can body is lowered and removed from the lifter plate and the contents are stored in the can body, the can body is placed on the lifter plate again with the flange side with the uneven portion facing up, and then After another lid is placed on the flange with a flange, the lifter plate is raised and the gap between the lid and the flange is used to deaerate and gas fill the inside of the can. The lid body and the flange portion are seamed together using a rear seaming roller. Therefore, when using the above-mentioned conventional method, the forming of the flange with the uneven part for degassing and gas filling and the work of tightening the lid to the other flange part are performed in separate processes, which makes the work process more complicated. In addition, if the material of the can body is a thin and relatively easily deformable metal plate, such as tinplate, ten-free steel, aluminum, etc., the flange part on the side that does not have a concavo-convex part for degassing and gas filling. When the lid is tightened, the flange side with the uneven part is compressed by the pushing force of the lifter plate, and the uneven part becomes flattened, which causes problems in the subsequent evacuation and gas filling operations. It was hot.

る。(Function) When manufacturing a gas-filling can according to the present invention, a cylindrical can body 5 having flanges 6 and 6' formed at both ends using a well-known flange forming mold (not shown) is used as shown in the first figure. The lifter plate is placed on the lifter plate 3 of the seaming machine A as shown in FIG. 3 and press the flange portion 6 together with the lid 8 against the lower surface of the seaming head 1, and in this state, either by rotating the seaming head 1 or by rotating the lifter plate 3, the lid 8 and This is for tightening the flange portion 6. At this time, due to the pressing force of the concave-convex mold 4 mounted on the lifter plate 3, the other (lower part in this embodiment) flange 6' of the cylindrical can body 5 has a flange 6' for degassing and gas filling. Uneven part 7
is formed, and a gas-filling can is manufactured.

大なるものである。(Effects) According to the present invention, when the bottom cover or the top cover is integrally tightened to one of the flanges formed at both ends of the cylindrical can body, the pressing force of the cylindrical can body is reduced. Since the concave and convex portions for degassing and gas filling are simultaneously formed on the other flange using the method, it is possible to simultaneously form the concave and convex portions for degassing and gas filling on the other flange. The formation of the part can be carried out in one step, which greatly simplifies the work process, and there is no risk that the uneven part will be flattened when the lid is tightened. It is also possible to use a metal plate that is thin (for example, about 0.20 m/m) and easily deformed, and as a result, the range of use of the material is expanded, and it is extremely effective in terms of resource conservation and economy. .
