  Alternatively, the width W1 in the vertical direction of each of the wrapping plates 13 is set to a width that reaches a substantially middle portion of the width W2 in the vertical direction of the side plates 3 and 5, and the outer side surfaces of the container side plates 3 and 5 are opposed to this. A laminated structure in which the inner side surfaces of 13 are bonded to the entire surface or bonded 14 to a point is used.

  As shown in FIG. 3, the film 9 covers the upper opening 8 of the container 1 and wraps over the outer surface of the bottom plate 2 from the outer surface of the wrapping plate 13 through the folded portion 16 of the wrapping plate 13. The wrapping force is received by the folded portion 16 of the wrapping plate 13 and the outer surface of the wrapping plate 13.

  The wrapping force, i.e., the tension accompanying the wrapping, is mainly applied to the connecting portions of the side plates 3 and 5 and the wrapping plate 13, i.e., the folded bent portion 16, and the yield strength is increased by the folded bent portion 16 and the wrapped plate 13 main body. In addition, the overlapping structure of the side plates 3 and 5 and the wrapping plate 13 cooperates to increase the wrapping strength and prevent deformation.

  Furthermore, the vertical width W1 of the wrapping plate 13 is made slightly wider than the vertical width W2 of the side plates 3 and 5. For example, when the width W2 in the vertical direction of the side plates 3 and 5 is 40 mm, the width W1 of the wrapping plate 13 is 43 mm, and further, the margin 18 for forming the folded portion is 3 mm or less.

  By bonding 14 the lower end of the wrapping plate 13 to the outer surface of the side plates 3, 5, the protruding portion 16 by the bent portion forming margin 18 is effectively formed. At the same time, the effect of urging the wrapping plate 13 in the outward direction is generated, the gap 15 is effectively generated, the elastic repulsive force (drag) against the wrapping force is increased, the absorption effect against the wrapping force is exhibited, and deformation Works effectively in prevention.

  In the case of wrapping, the protrusion 16 is pressed downward by the wrapping force, and the film 9 wrapped by the elastic force of the reaction is tensioned at the upper opening 8. This action is further amplified by applying a reaction force to the wrapping plate 13 and bonding the ends.
