Abstract: The present invention is a system for filling a container main body at least whose drum body is made of a flexible film, with a viscous material. A viscous material is charged by the charging means into container main bodies conveyed by the container conveying means, the drum body of the container main body is pressed by the pressing means to cause the surface of the viscous material to bulge, and the opening of the reinforcing component of the container main body is capped by the capping means, allowing the opening to be capped in an air-tight manner with a lid member while virtually all of the air inside the container main body is evacuated, and preventing air from being left over in the container main body so as to prevent hardening, curing and deterioration in the quality of the viscous material that can be caused by such remaining air.

Abstract: A gas sensor 1 includes a casing 10 which covers a sensing element 2 and includes two cylindrical members. The cylindrical members are axially disposed in such a manner as to overlap each other. Examples of the cylindrical members are a protector 11 (outer member) and a protector attachment portion 9a (inner member) of a metallic shell 9. A diameter-reduced portion 81 is circumferentially formed on the outer member 11 through, for example, caulking. A weld zone 83 is circumferentially formed at the diameter-reduced portion 81 so as to weld the outer member 11 onto the inner member 9a. Through formation of the diameter-reduced portion 81, a gap between the outer member 11 and the inner member 9a as measured at the position of the weld zone is reduced, thereby improving adhesion therebetween. As a result, possibility of a weld defect arising can be suppressed.
