As shown in FIG. 1, the body portion 10 is formed by bending a single wall plate 11 into a substantially cylindrical shape and bonding both end portions (left and right end portions) of the wall plate 11 in the longitudinal direction.

As shown in FIG. 4, the blank sheet S <b> 1 of the wall plate 11 is a rectangular flat plate extending linearly in one direction. The blank sheet S1 is a single-sided cardboard in which a core 52 is attached to the inner surface (one side) of a single liner 51.
A plurality of flutes 53 extending in the direction orthogonal to the longitudinal direction (circumferential direction) of the blank sheet S1 (short direction of the blank sheet S1) are arranged in the middle core 52 in parallel. That is, the corrugated uneven surface continuous in the longitudinal direction of the blank sheet S1 is formed on the core 52.
Each flute 53 of single-sided cardboard is exposed on the inner surface of the wall plate 11, and a single-sided cardboard liner 51 is exposed on the outer surface of the wall plate 11.

  As shown in FIG. 1, the body portion 10 is formed with a peripheral wall portion 12 in which the wall plate 11 is curved in a substantially cylindrical shape, and a bonding portion 13 in which both end portions of the wall plate 11 are bonded together. . The peripheral wall portion 12 is curved along the outer peripheral edge portion of the bottom plate 20 described later (see FIG. 3).

  In the present embodiment, the peripheral wall portion 12 is formed by curving both sides of the wall plate 11 with the central portion in the longitudinal direction of the wall plate 11 as a base point. A central portion in the longitudinal direction of the wall plate 11 is disposed at a front end portion of the peripheral wall portion 12.

The bonding portion 13 is a portion where the inner surfaces of both end portions in the longitudinal direction of the wall plate 11 are bonded together. The inner surfaces of both end portions of the wall plate 11 are adhesive surfaces on which an adhesive means such as an adhesive tape or an adhesive is provided, and the inner surface of one end portion of the wall plate 11 is bonded to the inner surface of the other end portion.
