Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a box for storing relatively heavy objects.

Conventionally, heavy items such as electric washing machines and refrigerators are placed in short bottom boxes made of cardboard or foamed plastic, covered with lid boxes, and then hung with bands. The band digs into a part of the lid box, and the lower end of the lid box in that part is bent.As a result, the lower end of the other parts of the lid box is lower than the bottom of the bottom box, and the height of the lid box ends up being lower than the standard. It will put pressure on things. As a result, the contents may be subjected to pressure greater than the design allowable, resulting in damage.

Furthermore, when the box is carried using rollers, the lower end of the lid box, which is lower than the bottom surface, gets stuck between the rollers and is no longer able to roll on the rollers. These drawbacks arise from the fact that the lower end of the lid box protrudes below the bottom surface of the bottom box. Therefore, the present invention is configured so that the lower end of the lid box does not fall below the bottom surface of the bottom box. There is one in which the bottom of the bottom box extends further in all directions than the size of the bottom of the accommodating portion of the bottom box (Fig. 1). For example, it can be seen in boxes for cakes, although they are lightweight. According to this method, the lower end of the outer box is stopped at the extension of this bottom surface, so there is no risk of it falling any further. However, with this box, it takes time and effort to fix a separate bottom frame onto the bottom plate, resulting in a high cost.

There is also a method of jointing the bottom box and the outer box using fasteners (Figure 2), but in this case, the fasteners are expensive and there is a risk of losing the fasteners. .

Therefore, the present invention has a structure in which an extension piece can be easily provided on the bottom surface without requiring any effort.

An embodiment shown in the drawings will be explained.

Figure 3 shows a developed view of the bottom box.
and side walls 2a to 2d, punching holes 4 are made on the side walls 2a to 2d at appropriate intervals along a fold line 3 (indicated by a dotted line) therebetween, and a flap 5 continuous with the bottom surface is provided.

Next, as shown in FIG. 4, the bottom box A is formed by bending each fold line 3 and raising each side wall 2a to 2d. At this time, each flap 5 is not bent and remains as an extension of the bottom surface 1, and the punched side wall 2
It protrudes horizontally to the outside of the bottom box.

Therefore, as shown in Fig. 5, the lid box B is replaced with the bottom box A.
(shown by the dotted line), the lower end 6 of this lid box B has a flap 5 which is an extension of the bottom surface 1 of the bottom box A.
It is locked at.

Since the box is configured in this way, even if the band 7 is applied to apply pressure to the lid box B, the lower end 6 of the lid box B is locked by the flap 5, so the lid box B can no longer be held. There is no need to worry about it going down.

As described above, according to the present invention, since it can be manufactured simply by punching, it is possible to provide a product that does not require much effort and is low in cost.
