[Industrial applications]

 The present invention relates to a packaging box.

[0002]

[Prior art]

 Conventionally, a packaging box body 30 of a cardboard paper material as shown in FIG. 3 has been known.

The box body 30 is generally called a wrap round case, and the items to be packaged are packaged as follows. First, an object to be packaged (not shown) is placed on the bottom plate 31 in the unfolded state, and the pair of first side plates 32, 33 connected to the front and rear edges of the bottom plate 31 are erected. Then, the second side plates 34, 35, 36, 37 connected to the left and right side edges of both the first side plates 32, 33 are bent inward at a right angle to the first side plates 32, 33, and the second side plates on the same side. The tips of the side plates 34 and 36 and 35 and 37 are butted against each other. Then, the first connecting pieces 38, 39 continuously provided on the left and right edges of the bottom plate 31 are vertically erected and abutted and bonded to the outer surfaces of the second side plates 34, 35, 36, 37. After that, the pair of lid pieces 40 and 41 continuously provided on the upper edges of both the first side plates 32 and 33 are horizontally bent inward. Then, the second connecting pieces 42, 43, 44, 45, which are continuously provided on the left and right edges of the both lid pieces 40, 41, are bent at right angles to the lid pieces 40, 41, and the second side plates 34, 35, 36, Abut and adhere to the outer surface of 37. In this way, the box body 30 is sealed.

Since the box body 30 has a simple structure as described above, it is easy to process a material such as a cardboard paper material and the manufacturing cost can be reduced. Further, since the box body 30 is for packaging the objects to be packaged at the same time as the assembling work is completed and the packaging work by the automatic machine is easy, the packaging work can be performed at a high speed.

However, the second side plates 34, 35, 36, 37 of the box body 30 are made of a single cardboard paper material. Therefore, the box body 30 has a low compressive strength in the vertical direction, and, for example, when it is packaged with a relatively heavy packaged object such as a beverage in a plastic bottle of 1 liter or more, it cannot be transported or transported. There is an inconvenience that the boxes 30 are crushed or distorted by stacking them during storage. Moreover, the box body 30 is carried by hanging fingers or the like on the tips of the second connecting pieces 42, 43, 44, 45. However, when packaging a relatively heavy package, The second connecting pieces 42, 43, 44, 45 of the box body 30 are weak in strength and may be torn when carried.

[Means for Solving the Problems]

 In order to achieve such an object, the present invention has a pair of first side plates, which are connected to the front and rear edges of a rectangular bottom plate, and which are vertically erected via fold lines, and are respectively placed on the left and right edges of both the first side plates. The second side plate, which is formed by stacking the folded pieces that are continuously arranged and connected to the respective leading edges, is folded inward through the folding line and overlapped, is folded inward perpendicularly to the first side plate through the folding line. A pair of first connecting pieces, which are bent and continuously provided on the left and right edges of the bottom plate, are vertically erected via a fold line, abut against the outer surface of the second side plate, and are bonded with an adhesive to bond the first side plates to each other. Bend a pair of lid pieces connected to the upper edge of the lid horizontally inward along the crease line and abut the leading edges of both lid pieces to each other, and connect them to the left and right edges of both lid pieces in a second connection The folded pieces, in which the strips are connected to their respective leading edges, are folded inward through the folded lines to form a polymer, and the second connecting piece is formed through the folded lines to Characterized by sealing with adhesive by contact with adhesive folding return pieces of the second connecting piece to the outer surface of the second side plate perpendicularly bent at one.

Further, when a cutout is formed in a part along the boundary between the second connecting piece and the folded piece, and the folded piece is folded back and polymerized on the second connecting piece, the second connecting piece It is preferable to form a grip portion on the tip edge.

[0009]

[Action]

 According to such means, the packaging box body of the present invention bends the side plates and the pieces along the respective fold lines, and abuts the connection pieces by abutting on the outer surface of the second side plate. Assembly is completed simply by bonding with a chemical. This facilitates the packaging by the packaging box body after placing the packaged object on the bottom plate in the unfolded state and enables the packaging work by the automatic machine.

Further, the second side plate is formed by folding back a folding piece continuously provided at the tip edge of the second side plate through a folding line and superposing it on the inner surface side of the second side plate. As a result, the second side plate is reinforced by the folded-back piece, and it is possible to wrap a relatively heavy object to be packaged by increasing the compression strength in the vertical direction as compared with the conventional one.

Then, a folding piece is continuously provided at each tip edge of the second connecting piece, and the folding piece is folded inward through a folding line to be superposed on the second connecting piece. The two-connecting piece has a relatively large thickness. By bringing the folded piece into contact with the outer surface of the second side plate and adhering it with an adhesive, the second connecting piece after sealing has a strong structure, and the second connecting piece is grasped and carried. It is possible. Moreover, since the second connecting piece is bonded and fixed to the place where the second side plate is reinforced by the folded piece, for example, a load from the outside is applied to a corner portion of one of the second connecting pieces and the load is applied. Is transmitted to one of the second side plates through the second connecting piece, the contact portion with the other second side plate that is in contact with the tip of the second side plate firmly supports the second side plate. The distortion and deformation of the second connecting piece and the second side plate are prevented.

Further, in the present invention, by forming the grip portion at the tip edge of the second connecting piece, it is possible to carry it more easily. When forming the grip portion, a notch portion may be formed in a part along the boundary between the second connecting piece and the folded piece. As a result, when the folded piece is folded back and overlapped with the second connecting piece, the notch portion is located at the front end edge of the second connecting piece, and a gripping portion that can be gripped by fingers or the like is formed.
