Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a packaging box using cardboard, which is used as a single packaging box especially during transportation and storage, and can be used at stores etc. as needed. This is a so-called subdivided packaging box that can be divided and used as two packaging boxes.

[Prior art and its problems] An example of conventionally dividing a cardboard packaging box and using it as two packaging boxes is, for example, Utility Model Application No. 58-180117.
This method is disclosed in Japanese Patent No. 59-136424 and the like. In the former method, items are stored and the box is assembled at the same time, and the material that becomes the box body after assembly is made up of a band-shaped mount. It lacks the convenience of being able to be divided into parts, and in addition, when assembling the box, the box cannot be completed unless the fixing pieces extended from the mount part are attached separately to the four sides of the end plate part. I couldn't escape it.

On the other hand, in the latter case, a two-layered partition plate is built into a box formed by dividing the outer flap in advance, and on both the upper and lower sides of this partition plate, there are lids that are also used as the outer flap after being divided. This box is constructed by forming boards, and when dividing the box, the sides of the box located between the two stacked partition boards are cut off using a knife. In this way, the latter type of divided packaging boxes require a knife to separate them, and cutting apart a relatively thick cardboard box is not only a tedious task, but also spoils the beauty of the divided boxes. There were also drawbacks.

[Means for Solving the Problems] Here, the present invention takes the following measures in order to solve the problems that are inevitable with the conventional divided packaging boxes. In other words, in a corrugated cardboard packaging box in which dividing means such as cutting tape or cut lines are provided on two opposing sides of the box and an outer flap connected to the sides, the left and right sides are separated at the location where the dividing means is provided through the perforated cut line. 2 connected to
The two partition plates are folded in half and assembled into the box, and a locking piece is extended on both ends of the two partition plates, and at least one of the upper side or the lower side of the locking piece is extended. A convex portion slightly higher than the height of the packaging box is formed on the side, and the locking piece is opened left and right to be inserted into the packaging box as an H-shaped partition plate. This is a divided cardboard packaging box. According to the present invention, it is possible to divide the box into left and right halves by using cut tape or a zipper applied to the center of the side panels of the cardboard box and the outer flaps connected thereto, and at the same time, the divided sides created by the division can be , the partition plate fixed to the original box functions as a side plate,
Even after division, a complete box is obtained.

Hereinafter, the present invention will be specifically explained based on the illustrated embodiments. FIG. 1 is a developed view of an A-1 type cardboard packaging box (hereinafter simply referred to as a packaging box).
side plates 1, 2 and outer flaps 3, 3 connected thereto;
A dividing means 5, 5, commonly called a zipper, is provided approximately in the center of 4, 4 by a cutting line. FIG. 2 is a developed view of the H-shaped partition plate according to the present invention, in which a rectangular corrugated sheet is divided into partition plates 8, 8 and locking pieces 9, 9 by perforation cut lines 6 and fold lines 7, 7. At the same time, the locking pieces 9, 9 are divided by uneven cutting lines 10, 10 which are extensions of the perforated cutting line 6. At this time, the height H' of the partition plates 8, 8 is the height H of the packaging box.
In addition, the upper side of each locking piece 9 is made to have a convex portion 9 by a concave-convex cutting line 10.
a is formed, and this convex portion 9a
The height of the partition plate 8 as shown in FIG.
It is made to be slightly higher than H', that is, to be higher by α.

To assemble the packaging box, as shown in FIG. 3, the H-shaped partition plate is folded in half along the perforated cut line 6, and each locking piece 9 is opened left and right to form an H-shaped partition. In this state, it is inserted and placed on the dividing means 5. After storing the articles in the box in this manner, the top surface is closed and sealed with each outer flap to complete the divided packaging box of the present invention.

Furthermore, when this is divided and used as two packaging boxes, the packaging box is first separated by the dividing means 5. That is, the parts of the two partition plates 8 are divided by the perforated cut line 6, and when this part is separated, the partition plates 8 are separated at the dividing plane of the box, as shown in FIG. It will function as the side plate of the box after it is divided.

In this case, the convex portion 9a of the locking piece 9 connected to the partition plate 8 is α larger than the height H of the box as described above.
As shown in Fig. 5, the outer flap 3 of the packaging box is
Or it bites into 4 and is fixed. That is, since the α portion is pressed down from above by the outer flap, when the partition plate plays the role of the side plate after dividing the box, the side plate will move as shown by the arrow in FIG. There is no risk of it coming out of the original box. In particular, when an item stored in a box swings inside while being carried, the impact may be transmitted from the inside to the partition plate 8, but even in such a case, the partition plate Since the protruding portion α of the height of the box in the stopper piece is bitten into the outer flap or is held down by the outer flap, there is no risk of the box falling off when handling the cargo.

Incidentally, the convex portions of the locking piece 9 may be formed only on the lower side of the opposite side, not depending on the uneven cutting line 10 as in this embodiment, or two convex portions may be formed on both the upper and lower end sides. good. If the direction of the corrugated cardboard flute in the locking piece 9 is vertical as shown in FIG. 2, this fixation will be very strong.

[Effects of the invention] As mentioned above, the divided cardboard packaging box according to the present invention not only provides a divided packaging box that can be divided and used simply by inserting a partition plate, but also allows the partition plate to be used when dividing. It can be easily divided through the perforation-like cutting lines formed without the need for a knife. In addition, the height of the locking piece attached to the partition plate that functions as a side plate after division is slightly higher than the height of the box by α, so this part bites into the outer flap when it is closed. It exhibits a unique effect in that it is held down by the , or outer flap and does not come out.
