【Example】

 Hereinafter, the illustrated embodiments of the present invention will be described. In the expanded state of the corrugated board of the present example shown in FIG. 1, 1 is a rectangular bottom plate, and body plates 2 and 3 are continuously provided on the peripheral edge in the longitudinal direction of the bottom plate, and folds 11 are formed on the peripheral edge in the width direction. The body plates 4 and 5 are connected in series via the. Connecting pieces 22 are continuously provided on both side ends of one body plate 2 via folds 21, and folds 23 inclined outward from the end of each fold 11 are provided. The portion is a glue margin portion 24 for adhering to the body plates 4 and 5, and the inner piece portion is a movable portion 25. Further, the reinforcing piece 8 is continuously provided on the open edge of the body plate 2 through the two parallel folds 81, and is bonded to the flexible piece portion 25 of the connecting piece 22 through the folds 82 on both side edges thereof. Reinforcing pieces 83 are continuously provided.

Inner standing pieces 6, 7 are connected to the body plates 4, 5 adjacent to the body plate 2 via two parallel folds 41, 51, and the inner standing pieces 6, 7 on the body plate 3 side are connected. Stopper pieces 61 and 71 are continuously provided on the side edges of the inner standing pieces 6 and 7 through folds 62 and 72, and locking tongue pieces 63 and 73 are projectingly provided on the open edges of the inner standing pieces 6 and 7. A locking hole 12 into which the locking tongues 63 and 73 are inserted is provided in the vicinity of the fold 11 of the bottom plate 1 at a position where the plate 7 is folded back.

Inserting pieces 32 are continuously provided on both side ends of the other body plate 3 via folds 31, and small engaging pieces 34 are provided on the inserting pieces 32 via folds 33. is doing. Further, a reinforcing piece 9 is continuously provided on the open edge of the body plate 3 through two parallel folds 91. Reference numerals 42, 52, 64 and 74 are handle holes. Further, reference numerals 65, 75, 84 and 92 denote gluing portions, and 26 denotes a gluing portion on the back surface.

Next, in the assembling, first, as shown in FIG. 2, the reinforcing piece 8 is internally folded and adhered to the body plate 2, and the glue margin portion 24 of the connecting piece 22 is glued and adhered to the body plates 4 and 5. Further, the reinforcing piece 9 is folded inward and adhered to the body plate 3, and the stopper pieces 61 and 71 are folded inward and adhered to the inner upstanding pieces 6 and 7 and conveyed to the use site in a flat state.

At the site of use, as shown in FIG. 3, when the body plates 4 and 5 are raised, the reinforcing pieces 8 and the body plate 2 are also in an upright state, and then the inner upright pieces 6 and 7 are folded inward to connect the connecting pieces. The inner standing pieces 6 and 7 are fixed by covering 22 and inserting the locking tongues 63 and 73 into the locking holes 12 and locking them. In this state, the three-sided body is formed upright, and the article is inserted and accommodated from the open side as shown in FIG.

Then, as shown in FIG. 5, the insertion pieces 32 are folded to stand up, and the locking pieces 34 are folded on the insertion pieces 32. As shown in FIG. It suffices to insert it in the insertion gap between the inner standing piece 6 and the inner standing piece 6. As a result, as shown in FIG. 7, the body plate 3 is also locked upright to form a box body having an open upper surface.

In this assembled state, as shown in FIG. 8, the insertion piece 32 and the locking piece 34 are sandwiched between the body plates 4 and 5 and the inner standing pieces 6 and 7, and the locking piece 34 is further stopped. , 71 are arranged inside and abutted against each other at their respective end faces, the outward movement of the locking piece 34 is prevented, so that the locking piece 34 does not come off. Therefore, the body plate 3 is also immobile and the box body is strongly held.

As described above, according to this example, the box body is easily assembled, the body plate 3 on the open side is easily closed, and the stopper pieces 61 and 71 lock the locking piece 34. Therefore, the body plate 3 cannot be opened.

Although the present example has the above-described configuration, the present invention is not limited to this. For example, the shape, length, and width of the stopper piece and the locking piece are not limited. Further, the connecting piece 22 which is continuously provided on the body plate 2 as in this example may not be used, and the entire connecting piece may be preliminarily adhered to the body plate as an adhesive piece. Furthermore, the reinforcing pieces of this example do not have to be arranged in series.
