This known tank device includes a tank for storing a liquid to be insulated or cooled, And a plurality of unit jackets provided in parallel with each other at an interval on the outer peripheral surface. The plurality of unit jackets are joined to the tank by welding, cooperate with a body plate of the tank to define a flow path of a heat or coolant body extending in a predetermined direction, and to maintain a temperature or a temperature for keeping the stored liquid warm or cool. A coolant flows through such a flow path.

[0003]

In such a tank apparatus, there are the following problems to be solved. First
In addition, the cross section of the unit jacket is formed in a substantially semicircular shape, and its thickness is formed substantially uniformly over the circumferential direction. Therefore, when welding the unit jacket to the tank, it is difficult to increase the build-up of the weld, and due to this, the strength of the weld cannot be sufficiently maintained. To solve such inconveniences, the thickness of the unit jacket may be increased, but if the thickness of the entire unit jacket is increased, the amount of material used increases, and the weight of the unit jacket increases, Manufacturing costs rise.

[0004] Second, the unit jacket is joined by bringing the end face of the unit jacket into contact with the surface of the body plate of the tank and welding the corners of the unit jacket and the body plate. It is difficult to make the build-up by welding as large as necessary in the proper welding, and it is also difficult to secure sufficient welding strength due to this.

An object of the present invention is to provide a container jacket structure which can weld a unit jacket to a container as required and can secure a sufficient welding strength.
