[Industrial applications]

 The present invention relates to a cardboard box for packing products, which becomes a carrying box when returning home.

[0002]

[Prior art]

 In general, cardboard boxes for product packaging are formed in a rectangular parallelepiped that is easy to stack in order to enhance the loading efficiency during transportation. For this reason, it is difficult for consumers, etc. to carry products when they take them home in cardboard boxes.

Therefore, conventionally, a packaging box has been proposed which is a rectangular parallelepiped for transportation but serves as a carrying box when taking out (Japanese Utility Model Publication No. 59-126923). This consists of connecting the lid plate from the upper edge of the side plate that forms one of the front and rear side plates of the box, and the hand plate from the upper edge of the other side plate so that the hand plate can be folded in two. The hand-holding part formed on the hand-holding plate is exposed upright from the cut groove formed in the central part of the lid plate.

[0004]

[Problems to be solved by the device]

 However, in the conventional packaging box, the hand part exposed above the cover plate is flattened by crushing during transportation or stocking, but the thickness of the hand part protrudes above the cover plate. As a result, there is a problem that the upper surface of the packaging box does not become flat and becomes unstable when stacked.

Further, since the cover plate is provided with a cut groove for inserting the handbag portion, the distance from the end of the cut groove to the edge of the cover plate is short, and the portion of the cover plate having this short distance in the handhold posture is short. There is a problem that the force concentrates and breaks easily. Furthermore, the weight when carrying the bag is concentrated on the bent part of the carrying plate, and there is a problem that the bent part is easily broken. The present invention has been made with this point in mind, and it can be stably stacked during stocking and transportation, but it is a cardboard box for packaging that becomes a carrying box with sufficient strength when taking it home. The purpose is to provide a box.

[0006]

 In order to achieve the above-mentioned object, the present invention is to connect left and right end plates to the left and right sides of the front plate, connect the rear plate to one of the left and right end plates, and connect the other end plate to the rear plate. Connect the connecting pieces to the side edges of the front and rear side plates, and the bottom plate from the lower edges of the front and rear side plates, and connect the lower ear pieces from the lower edges of the left and right gable plates to the inner lid plate from the upper edge of the front plate. In addition to connecting the outer cover plates from the upper edge of the rear side plate, the folding flaps from the upper edges of both cover plates, and the triangular locking pieces from the upper edges of both gable plates. Then, finger insertion holes are provided through the upper edge portion of the inner and outer cover plates and both folding flaps, and notches are formed at both ends of the connection ridgeline between the inner and outer cover plates and both folding flaps. A vertical slit hole is provided through the triangular locking piece to connect the inner lid plate to the front plate near the ridgeline. A slit flap along the connecting ridge line is provided through, both triangular locking pieces and the inner cover plate are folded inward, the outer side of the inner cover plate is covered with the outer cover plate, and the folding flaps are connected to the outer cover plate. The stackable posture in which the upper surface is flat by inserting into the slit groove hole, and with both triangular locking pieces left outside the box, raise the inner and outer lid plates at the center in the depth direction to raise both lid plates. The inner surfaces of the parts contact each other, fold back each folding flap and assemble so that the four finger insertion holes overlap, and insert the rising parts of the inner and outer lid plates into the slit holes of the triangular locking piece. It is characterized by being configured so that it can be assembled in such a posture that it can be held by hand.
