、水撃などの外圧に対して制えることができなくなる。BACKGROUND ART Recently, water meters with electronic gear mechanisms for detecting water volume have become popular. In addition, this water meter non-contactly detects the impeller rotating with the amount of water used, integrates and displays the integrated value electrically, and transmits the integrated value to the outside in a predetermined message format. It has a function. Therefore, compared to the above-mentioned conventional mechanical water meter having a gear mechanism, aging characteristics and sensitivity are improved, and the failure rate can be significantly reduced. By the way, since computerized water meters contain high-density electronic components such as LSI, and must be used for metering over a long period of time (several years), a high level of airtightness is required. However, in mechanical water meters, the
Sealing is done by holding the ring in place and tightening the screw.
The sealing method applied to such mechanical water meters cannot achieve the high airtightness required for electronic water meters. Therefore, some attempts have been made to seal containers for water meters by cold pressure welding. In this sealing method using cold pressure welding, the thickness of the container must be reduced in order to obtain good bonding properties. However, as the thickness of the container decreases, its mechanical strength decreases significantly, making it unable to withstand external pressures such as water hammer.
そこで、電子部品を収納する冷間圧接に適した薄肉の内
部容器を厚肉の外部容器に収納させ、この外部容器によ
シ外圧から内部容器を肋膜する方法などが採用されてい

が要望されていた。Therefore, a method has been adopted in which a thin-walled inner container suitable for cold pressure welding that stores electronic components is housed in a thick-walled outer container, and the inner container is sealed from external pressure by the outer container. However, such a double-walled container requires a large number of parts and a complicated processing process, so there has been a demand for rationalization.

利点を有する。The method for producing a sealed container of the present invention is to form the flange of a sealed container to be cold-welded into a stepped shape with a thick wall part on the inside and a thin wall part on the outside, and then cold-weld the thin wall part. Since the parts are pressure-welded, the thin-walled portion improves the cold-pressure weldability, and as a result, the container is completely sealed. Moreover, the thick inside of the flange can be used to engage other parts of the sealed container.
This has the advantage that fastening can be performed without causing deformation of the collar.
