In addition, the 3rd mountain fold line c has penetrated in the center part of the left-right direction of the 2nd cut-and-raised piece 20b so that it may penetrate in an up-down direction.

  The storage auxiliary material 10 formed as described above in the unfolded state is formed into a three-dimensional shape by folding it into mountain folds at the respective fold lines a to f, so that the upper opening edge 6 of the container 1 covered with the curing sheet 9 is obtained. It is designed to be attached along the line. The three-dimensional storage auxiliary material 10 is folded in two so that the outer portion 13 and the inner portion 14 face each other by folding the first mountain fold line a and the second mountain fold line b (inverted U-shaped cross section). At the same time, the main body portion 11 and the pair of sub-body portions 12 are positioned in a U shape in plan view by bending the third mountain fold line c. Specifically, as shown in FIG. 2, one container 1 is covered with two storage aids 10. The pair of storage assisting materials 10 covers each main body portion 11 on a pair of opposing edge portions 6 a of the container 1, and corners between the adjacent edge portion 6 a and the adjacent edge portion 6 a. Adhering to the container 1 is performed so that each sub-body part 12 is covered over a part of the adjacent edge part 6a (near the corner part).

  In the storage auxiliary material 10 that covers the container 1, the outer portion 13 that covers the outer surface of the container 1 is raised obliquely upward and inward from the outer portion 13 a of the main body 11 by mountain folding at the second mountain fold line b. The first cut-and-raised piece 20a is a locking portion 22 that is locked to the lower surface of the flange 4 of the container 1 so as to stretch from below. At this time, the first cut-and-raised piece 20a serving as the locking portion 22 is inserted between the engagement protrusion 7 of the flange 4 and the outer surface of the container 1 as shown in FIG. Functions as a retainer for maintaining the state of the first cut and raised piece 20a being locked to the lower surface of the flange 4.

  The container 1 covered with the curing sheet 9 and the storage auxiliary material 10 in order as described above is stored by being stacked in a nesting shape as shown in FIG. 1, but at this time, the outer surface of the container 1b in the upper position is It comes into contact with the inner portion 14 of the storage auxiliary material 10 placed on the container 1a at the lower position. That is, the inner portion 14 of the storage auxiliary material 10 functions as a spacer portion 23 that forms a gap S between the outer surface of the upper container 1b and the inner surface of the lower container 1a. According to the gap S, the curing sheet 9 covering the inner surface of the lower container 1a can be prevented from contacting the outer surface of the upper container 1b (specifically, the curing sheet 9 covering the outer surface). In particular, in the storage auxiliary material 10 in which the paperboard 10a of this example is formed of corrugated cardboard, since the thickness dimension of the inner portion 14 that functions as the spacer portion 23 can be increased, a relatively wide gap S is formed. The curing sheet 9 covering the inner surface of the lower container 1a and the outer surface of the upper container 1b (specifically, the curing sheet 9 covering the outer surface) can be made difficult to contact.

  Therefore, when the upper container 1b is pulled upward from the lower container 1a, the curing sheet 9 placed on the lower container 1a rises together with the upper container 1b due to friction with the upper container 1b. The risk of getting lost is reduced. Further, in the storage auxiliary material 10 that covers the container 1a in the lower position where the inner portion 14 is in contact with the container 1b in the upper position, the locking portion 22 provided on the outer side portion 13 of the storage auxiliary material 10 is provided with the curing sheet. 9, the container 1 is locked from below, the inner portions 14 b of the sub-body portions 12 are pressed against the inner surface of the container 1 at both ends of the inner portion 14 a of the main body portion 11, and the engaging protrusion 19 Is inserted into the engaging recess 18 to restrict the turning up of the main body portion 11 and each sub body portion 12, so that the upper container 1b is retracted upward from the lower container 1a. It is also effectively prevented that the auxiliary material 10 comes off from the lower container 1a. That is, even when the upper container 1b is pulled upward from the lower container 1a, the storage auxiliary material 10 is maintained in a state of covering the lower container 1a via the curing sheet 9. It is possible to prevent the curing sheet 9 from being detached from the lower container 1a by the storage auxiliary material 10. That is, according to the storage auxiliary material 10 configured as described above, which covers the upper opening edge 6 of the container 1 via the curing sheet 9, when the upper container 1b is pulled upward from the lower container 1a, Of course, it is possible to prevent the curing sheet 9 from being detached from the container 1a, and it is also possible to prevent the curing sheet 9 from being turned up from the lower container 1a, and the complicated operation of re-covering the curing sheet 9 is avoided. It is.

  Further, when the storage auxiliary material 10 is placed on the container 1, the punched hole 21 formed when the cut and raised piece 20 constituting the locking portion 22 is cut and raised can be used as the handle hole 24. . That is, according to the finger inserted into the punched hole 21, the container 1 can be handled easily, such as being hooked on the lower surface of the flange 4 of the container 1 and pulling the container 1 upward. In particular, when the punched hole 21 formed when the first cut and raised piece 20a is cut and raised is used as the handle hole 24, the handle hole 24 with respect to the engaging protrusion 7 projecting from the lower surface of the flange 4 is used. It is possible to hook the finger that has passed through the cover with less slipping, and the container 1 can be handled very easily. Thus, the cut-and-raised piece 20 of the storage auxiliary material 10 always has a punched hole 21 when the storage auxiliary material 10 is cut and raised. This eliminates the need to newly provide a handle at another site, and simplifies the configuration of the storage aid 10.
