Therefore, the third U-shaped portion 55 can be prevented from coming out of the hole portion 26 when a heavy object is put in the cylindrical body 6 and the handle 15 is held.

In the above embodiment, as shown in FIG. 2, the case where the protrusion of the reinforcing portion 49B of the sticking base portion 46 of the joining margin 45 is reduced is illustrated, but the protrusion of the reinforcing portion 49B is as shown in FIG. In addition, the size of the lower side 6c of the first side plate portion 2 or the third side plate portion 4 may be set to the same level.
When the protrusion of the reinforcing portion 49B is provided in this way, the area to be bonded to the peripheral wall portion 27 of the hole portion 26 of the first side plate portion 2 is increased, and the rigidity of the peripheral wall portion 27 can be increased.
Moreover, although the case where the hell bottom was employ | adopted was illustrated as the bottom part 13 of the said embodiment, what is called a one-touch bottom as shown in FIG. 7 can also be employ | adopted as long as the dimensional relationship is suitable.

  Further, the sticking tip 47 may not be a part of the joining allowance 45, for example, as shown in FIG. 8, separated from the joining allowance 45 and at least a part (for example, a handle) It may be affixed in advance on the inner surface of the portion 41 and connected to the tip edge of the third U-shaped portion 55. Even with such a configuration of the sticking tip portion 47, the third The U-shaped portion 55 can be pulled out from the hole portion 26 as the first U-shaped portion 20 is raised, and the same operations and effects as in the above embodiment can be obtained.

Further, the structure of the handle 15 of the present invention is not limited to the cylindrical body 6 composed of four side plate portions, and can also be applied to the cylindrical body 6 having a pentagon or more in plan view.
In this case, the 1st U-shaped part 20 is formed in the side-plate part of the one end side which connected the side-plate part to one direction on both sides of a crease | fold. The direction of the first U-shaped portion 20 is such that the leading ends of U-shaped straight lines extending in parallel with each other, in other words, the U-shaped starting end and terminal end face the edge side of the side plate portion, and FIG. Is directed in the direction in which the side plate portions are connected.

  Further, the joining margin 45 or the second U-shaped portion 47 and the third U-shaped portion 55 are formed on the side plate portion on the other end side where the side plate portions are connected in one direction across the fold. The direction of the second U-shaped portion 47 is such that the U-shaped straight ends of the U-shape extending in parallel with each other are directed toward the crease between the joint margin 45 and the side plate portion, and the handle portion 41 is directed to the opposite side. The third U-shaped portion 55 may be formed so as to be substantially line symmetrical with the second U-shaped portion 47 so that the top side 52 of the second U-shaped portion 47 is shared.

  Thus, even when the present invention is applied to a side plate portion of a cylindrical body having a pentagon or more in plan view, the same functions and effects as those obtained in the above embodiment can be obtained.
