Here, with respect to the container side piping section 4 fixed to the hinge mounting base 5 by the holding metal fitting 52 and the bolt 53, the lid side piping section 3 is rotated around the axis X of the container side piping section 4. The lid 2 is pivotally connected to the container 1 by pivoting the lid-side piping portion 3 with respect to the container-side piping portion 4. Lid 2
Can be opened and closed.

A connecting portion for rotatably connecting the lid-side piping portion 3 to the container-side piping portion 4 is, as shown in FIG.
The cover 2 is formed by a threaded joint portion 5 in which a female thread portion 30 provided on an inner periphery of an end portion of the lid side pipe portion 3 is screwed to a male thread portion 40 provided on an outer periphery of one end of the container side pipe portion 4.
Is a direction in which the screw joint 5 is loosened,
The rotation in the direction in which the lid 2 is closed is set to the direction in which the screw joint 5 is tightened.

When the lid 2 is opened and closed, the lid-side piping section 3 and the lid 2 rotate together, so that the lid-side piping section 3 does not obstruct the opening and closing of the lid 2 as a matter of course. That,
Since the lid-side piping portion 3 and the lid 2 are rotated by using the screw joint 5 between the lid-side piping portion 3 and the container-side piping portion 4, a rotation shaft dedicated to opening and closing the lid 2 is provided. Need not be separately provided, and the assembly and disassembly of the lid-side piping section 3 and the container-side piping section 4 can be easily performed. In particular, the container-side piping section 4 is fixed by bolts 53 and can be removed from the container 1 in order to facilitate assembly and disassembly.
For example, it is to facilitate cleaning of the inside of the pipe.

Further, the male screw part 4 in the screw joint part 5
