And at least one or more protrusions integrated with the outer wall surface of the double side wall portion and the end wall portion in the opening, and the engagement hole portion for forming the side wall portion and the end wall portion of the double structure; A plurality of packaging boxes provided at the four peripheral portions of the bottom portion for engaging with the projection portions, and when the packaging boxes are stacked, the projection portions are fitted into the fitting holes at the bottom portion. It is a packaging container that is positioned together.

  The packaging box is made of corrugated cardboard, and has a lateral flap connected to the outer wall surface of the side wall or end wall, and is connected to the outer wall surface and is adjacent to the lateral flap and has an oblique cut line and has a substantially trapezoidal shape. And a reinforcing piece having a stepped portion on the outside, and forming corner receiving portions at the four corners to prevent the packaging box from dropping to the lower step when the packaging boxes are stacked, and the holes provided near the four corners of the bottom portion The stepped portion of the reinforcing piece is engaged and reinforced in the height direction.

According to the packaging container of the present invention, it is possible to assemble the packaging box only by an easy operation of bending and uneven fitting, and to facilitate disassembly and disposal.

  In addition, when transporting by stacking, reliable positioning can be achieved by fitting with the fitting hole and projection, and it is difficult to load and disassemble together with the corner receiving parts at the four corners, and the side wall and end wall are double structures. Therefore, it is possible to sufficiently protect the tray storing the product.

  At least one or more protrusions integrated with the outer wall surface of the double side wall portion and the end wall portion are provided in the opening, and the engagement hole portion for forming the side wall portion and the end wall portion of the double structure; A plurality of packaging boxes provided at the four peripheral portions of the bottom portion with engaging hole portions that engage with the protruding portions, the packaging box is made of corrugated cardboard, and is connected to the outer wall surface of the side wall portion or the end wall portion. When the packaging box is stacked, the lower stage is provided with a flap and a reinforcing piece that is connected to the outer wall surface and is adjacent to the lateral flap, has an oblique cut line, has a substantially trapezoidal shape, and has a stepped portion on the outside. In addition to forming corner receiving portions at the four corners to prevent falling, the stepped portions of the reinforcing pieces are engaged with holes provided in the vicinity of the four corners of the bottom portion to reinforce the packaging box in the height direction. When stacking, the protrusion is fitted into the fitting hole at the bottom and positioned.

  In FIG. 1, 1 is a bottom part, 2 and 3 are side wall parts, 4 and 5 are end wall parts, 6 and 8 are projection parts, 7 and 9 are fitting holes, 10 is a lateral flap, 11 is a reinforcing piece, 12 Is an engagement hole, 13 is a hole, and 14 is a score line.

  The protruding portions 6 and 8 are formed by cutting, and the reinforcing piece 11 is connected to the side wall portion 2, separated from the side wall portion 3 by an oblique cutting line 14, and next to the horizontal flap 10 connected to the side wall portion 2. Adjacent to each other.

  Here, a method for assembling the packaging box will be described. The paperboard from which the corrugated cardboard is cut has the side walls 2 and 3 and the end wall parts 4 and 5 connected to the four sides of the bottom 1 and bends to form a double-structured wall. At this time, the side wall portion 2 and the end wall portion 4 are outer wall surfaces, and the side wall portion 3 and the end wall portion 5 are inner wall surfaces.

  First, the side wall part 2 is bent along a crease line with the bottom part 1, and the lateral flap 10 is bent inward. Next, the end wall portion 4 is bent along a crease line with the bottom portion 1, and the end wall portion 5 is further bent inward along a crease line with the end wall portion 4. At this time, when the lateral flap 10 is sandwiched between the end wall portion 4 and the end wall portion 5 and the protrusion 5a is inserted into the fitting hole portion 7, the state shown in FIG. In the present embodiment, the fitting hole 7 also serves as an engagement hole.

  Next, the side wall 3 is bent inward (in the direction of the arrow) along the crease line with the side wall 2, and the protrusion 3 a provided outside the side wall 3 is inserted into the engagement hole 12 provided in the bottom 1. Further, the reinforcing piece 11 is bent in a crease line and a right angle direction with the side wall portion 2 to form a corner receiving portion, and the convex portion of the reinforcing piece 11 is inserted into the hole portion 13 of the bottom portion 1 to complete the packaging box. To do.

  As shown in FIG. 3, when stacking the finished packaging boxes, the projection 6 projecting from the end face of the double-structured wall is fitted with the fitting hole 7 provided in the bottom 1 of the upper packaging box.
