  2. Description of the Related Art Conventionally, as a packaging box for storing packs of fruits, fresh vegetables, and the like and stacking them, there is a packaging box formed by punching a single plate-shaped member into a predetermined shape and bending along a fold. A bottom plate having a square shape, a front plate, a rear plate, a left plate, and a right plate provided integrally with four sides of the bottom plate via folds; and four top plates provided at four corners of the upper surface of the opening. In some cases, the objects are made easier to see from the outside, and when the packaging boxes are stacked in multiple stages, the contents are protected by a top plate so as not to be damaged (for example, see Patent Document 1).

JP 2005-170479 A

  However, in the above-mentioned Patent Literature 1, since the top plate portion covers a part of the pack of the stored fruits and fresh vegetables, it is difficult to remove the stored pack from the packaging box at the time of display.

  Therefore, an object of the present invention is to provide a packaging box that can be stacked in multiple layers without damaging the contents and that allows the contents to be taken out favorably.

  In order to achieve the above object, a packaging box according to the present invention includes a square bottom plate, a front plate, a rear plate, a left plate, a right plate, and a left plate integrally provided on four sides of the bottom plate through folds. A left front top plate is provided integrally with a fold, and is disposed on a corner upper surface of the left side plate and the front side plate, and is provided integrally with a fold on the left side plate, and the left side plate and A left rear top plate disposed on an upper surface of a corner with the rear plate, and a right front side provided integrally with a fold on the right plate and disposed on an upper surface of a corner of the right plate and the front plate. It is formed by assembling a plate-like member having a top plate and a right rear top plate provided integrally with the right side plate via a fold and disposed on a corner upper surface of the right side plate and the rear side plate. In the packaging box, the left front side top plate, the left rear side top plate, the right front side top plate, and the right rear side top plate Through the fold, while being formed to be able to be bent on both the inner surface side and the outer surface side of the plate-shaped member, the left front side top plate and the right front side top plate project in the front side plate direction The left rear-side top plate and the right rear-side top plate protrude in the direction of the rear-side plate, and are bent together with a folding piece that can be bent on both the inner surface side and the outer surface side of the plate-shaped member through a fold. Through the eyes, a folding piece is provided on each of the inner surface side and the outer surface side of the plate-shaped member, and each of the locking pieces is provided at an upper edge of the front plate and the rear plate. A first locking hole to be locked includes a corner outer surface of the front side plate and the left side plate, a corner outer surface of the front side plate and the right side plate, and a corner of the rear side plate and the left side plate. Second locking holes for locking the locking pieces are formed on an outer surface and a corner outer surface of the rear plate and the right side plate, respectively. The left front side top plate, the right front side top plate, the left rear side top plate, and the right rear side top plate are each bent toward the inner surface side of the plate-like member via a fold, and each of the locking pieces is An accommodation state in which the plate-like member is bent toward the inner surface side through a fold, and the locking pieces are locked in the first locking holes, the left front top plate and the right front top plate, respectively. And the left rear top plate and the right rear top plate are each bent to the outer surface side of the plate member via a fold, and each of the locking pieces is connected to the plate member via a fold. Is bent to the outer surface side of each of the above, and it is possible to recombine into a state in which the stored pieces are taken out in which the respective locking pieces are locked in the respective second locking holes.

  Further, each fold provided between the left side plate and the left front side top plate and the left rear side top plate, and each fold provided between the right side plate and the right front side top plate and the right rear side top plate, respectively. A lead crease or an inverted crease is provided on each of the folds and the folds provided between the left front side top plate, the left rear side top plate, the right front side top plate, and the right rear side top plate and each of the locking pieces. It is suitable to put.

  According to the packaging box of the present invention, the left front side top plate, the left rear side top plate, the right front side top plate, and the right rear side top plate are each bent toward the inner surface side of the plate-like member through a fold, and The pieces are bent toward the inner surface side of the plate-like member through the folds and locked in the respective first locking holes, so that the left front top plate, the left rear top plate, and the right front side The top plate and the right rear top plate can be arranged, and there is no danger of damaging the contents even if the packaging boxes are stacked in multiple stages.

  Further, when taking out the contents, the left front side top plate, the left rear side top plate, the right front side top plate, and the right rear side top plate are bent to the outer surface side of the plate-like member through the folds, respectively, and The entire upper part of the packaging box can be largely opened by bending the stopper piece to the outer surface side of the plate-like member through the fold and locking it in each second locking hole. Can be favorably taken out of the packaging box.

  Further, each fold provided between the left side plate and the left front side top plate and the left rear side top plate, each fold provided between the right side plate and the right front side top plate and the right rear side top plate, respectively, The top plate, left rear top plate, right front top plate, right rear top plate and each fold provided between each locking piece are provided with a lead crease or a reverse crease, so that each top plate and each fold are creased. In addition, it is possible to satisfactorily bend both the inner surface side and the outer surface side of the plate member.
