Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box suitable for packaging a heavy load such as a large-sized television, a washing machine, a room air conditioner, etc., and particularly, a front side wall of the packaging box is cut at the time of unpacking. By doing so, it is possible to remove a heavy object by moving it forward from the front without lifting it high, and reducing the man-hours at the time of unpacking to make it easy to take out a heavy object.

[0002]

2. Description of the Related Art In recent years, televisions and the like have become larger and wider, and high-inch televisions having a size of 28 inches or more have begun to spread to general households. In the case of 28-inch TV, the weight is about 46 kg, and the external dimensions of the product are 699 x 492 x 499.
mm, but much more for high-inch TVs. As a packaging box for packaging and shipping heavy products such as a large-sized television and a washing machine, a cardboard box of A-1 type made of double-sided cardboard sheets has been used.

[0003]

However, according to such a conventional corrugated board box, there is a drawback that it is difficult to take out the article to be packed stored inside. That is, in the conventional cardboard box, it is necessary to lift and remove the article to be packed up to the height of the box when unpacking. However, large televisions, washing machines, air conditioners, etc. are heavy and bulky, and since cushioning materials are installed inside the boxes, it is necessary to lift the items to be packed while removing the cushioning materials. The workability was extremely poor, and the labor and man-hour burden on the worker were extremely large.

In view of the above-mentioned drawbacks of the prior art, the present invention reduces the man-hours required for unpacking at the time of unpacking, so that the front side wall of the packaging box can be cut and opened very easily, resulting in a heavy load. The purpose is to provide a heavy-weight packaging box that can be taken out from the front side without lifting it up, and can be taken out easily even by an amateur without damaging the item to be packed, and that has good workability during unpacking. And

[0005]

In order to achieve the above object, the present invention connects a pair of left and right end plates and a pair of front and rear side plates in one direction, and provides flaps on the upper and lower sides of the end plate and the side plates. In a series of A type corrugated boxes, notches along the upper side and a pair of front unpacking zippers extending from one end inside the notches toward the lower side are formed on both left and right sides of the front side plate. With this configuration, it is not necessary to lift the item to be packed to the full height of the box when taking it out when unpacking.

The front unpacking zipper may be formed along a ruled line provided at the boundary between the front side plate and the left and right side plates.

[0007]

[Function] When the notch along the upper side of the front side plate and the pair of front unpacking zips extending from one end inside the notch toward the lower side are cut, only the front part from the top is left from the top while keeping the shape of the box. It is opened to the bottom.

[0008]

Embodiments of the heavy-duty packaging box of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a development view showing an embodiment of the present invention. In the drawing, reference numerals 1 and 3 are a pair of side plates 2 and 4 are a pair of end plates, which constitute a box-shaped box body. . It should be noted that three of the side plates 1 and 3 are front side plates and 1 is a rear side plate. Further, 5 is a joint piece connected to the side edge of the side plate 1, both of which are connected to each other through a fold line (also referred to as a ruled line), and on the lower side of the pair of side plates 1 and 3 and the end plates 2 and 4. The lower flaps 6a and 6b, which serve as the bottom plates, are provided so as to extend through the respective fold lines.

Upper flaps 1a and 3a, which serve as lids, are connected to the upper sides of the side plates 1 and 3 by extending them through a fold line, and a pair of left and right insertion grooves 7 and a bending piece 8 are provided at substantially the center thereof. Provide by cutting.

Engaging flaps 2a are provided on the upper sides of the end plates 2 and 4,
4a is extended through a fold line, and insertion pieces 9 and 9 which can be inserted into the insertion groove 7 are formed on the upper side of the 4a through fold lines 10 by vertical cuts.

On the other hand, in the front side plate 3, notches 11 are formed along both sides of the front side plate 3 along the upper side, and the notches 11 are formed.
An unzipping zipper (cut line) 12 extending from the inner end 11a toward the lower side of the side plate is provided. This zipper 1
The lower end of 2 can be gently bent to reach the lower corner of the side plate 3 as in the embodiment, but it should be stopped slightly above the lower side of the side plate and the lower part left uncut. You may

Further, the shape of the zipper can be provided in an inverted C shape which is closed downward as shown by reference numeral 12b in FIG. Further, as shown in (3) of FIG. 3, it is possible to form an unpacking cutting line composed of the zipper 13 along a ruled line (folded line) provided at the boundary between the front side plate 3 and the left and right end plates 2, 3.

In FIG. 1, reference numeral 14a is a handling hole, and 14b is a hole for fixing the cushioning material provided in the lower flap 6b. From the styrene foam attached to the bottom of the article G to be packed in this fixing hole. The cushioning material 15 is fixed as shown in FIG.

The heavy-duty packaging box of the present invention has the above-mentioned structure, and at the time of assembly, a pair of side plates 1 and 3 and a pair of end plates 2 and 4 through the joining piece 5 as in the conventional method.
Are connected to form a box-shaped box body, and then the lower flaps 6a and 6b are bent inward to form a bottom portion, thereby forming a top-opening box.

After assembling in this way, as shown in FIG. 4, a packaged product G such as a TV covered with the film F is delivered. At the time of delivery, the cushioning material 15 is attached to the corner of the article G to be packed. Then, the flaps 1a and 3a to be the inner lids are bent inward and abutted, and then the engagement flaps 2a,
3a is folded inward, the insertion pieces 9 are inserted into the insertion groove 7 through the fold line 10, and the packing is completed.

To take out the above-mentioned article G to be packed, as shown in FIG. 6, a notch 11 along the upper side of the front side plate 3 and a pair of front unpacking parts extending from one end inside the notch to the lower side. Cut the zipper 12, 12b or 13. In this way, when the front side plate 3 is opened as shown in the figure, only the front portion of the front side plate 3 is opened from the top while the box shape is left. Therefore, it is not necessary to lift the heavy item to be packed to the full height of the box, and even if the cushioning material is attached, the styrofoam cushioning material is not removed one by one without moving the cushioning material together with the packaging material to the front. It can be taken out easily just by moving it.

[0017]

As described above, the heavy-weight packaging box according to the present invention can be taken out from the front without lifting heavy items, and can be easily taken out by an amateur without damaging the item to be packed. This has the effect of making the workability during packaging extremely good.
