Description

[Detailed description of the invention] The present invention relates to a packaging box that is most suitable for packaging small-sized audio products such as radio cassettes, amplifiers, tuners, and cassette decks, and in particular to a packaging box that is most suitable for portable use such as taking it home. be.

Traditionally, many packaging boxes of this type have been closed by simply folding four lid pieces, but in the present invention, the lid pieces are used to form a handle for convenient portability. In this case, even though it is a small product, it may be packed with quite heavy items, so it is of course important to make the lid plate particularly strong and to be able to close it easily. To provide a packaging box in which a box main part does not hang down from the bottom.

Embodiments of the present invention will be described below based on the drawings.

1 in the figure is the box body, and as shown in Figure 1, the four side walls are formed by carving folds a, l), c, and d in a cardboard base paper, etc., and the box is connected to each of the four side walls. The bottom plate is constructed by overlapping each bottom plate flap.

Each cover piece 2, 3°4.5 extended on the four sides of the box body 1
Cut lines 6 and 7 are provided from the tip edges of one of the opposing lid pieces 2 and 3, and the lid is inserted through a fold f carved between the tips of the cut lines 6 and 7. There is a handle piece 8 in the center of the tips of pieces 2 and 3.
,9 are formed.

Further, a lid piece insertion groove 10.11 is provided along the fold f from the tip of the cut line 6.7.

The width of the lid piece insertion groove 10.11 is made to correspond to the thickness of the base paper, that is, the thickness of the lid pieces 4 and 5.

An insertion tongue piece 1 has locking claws 13 formed inwardly through a fold g at both ends of the other opposing lid pieces 4 and 5.
2 will be provided.

In this case, as shown in the developed view of FIG.
It is formed by cutting the side into a roughly ear shape.

Insertion grooves 14 and 15 for inserting the insertion tongue piece 12 are formed in the lid pieces 2 and 3 along the fold e at the base end thereof.

The width of the insertion grooves 14 and 15 is also made to correspond to the thickness of the base paper.

Note that 16 in the figure is a finger hole formed in the handle pieces 8 and 9.

In order to facilitate assembly, the lid pieces 4 and 5 have a crease in the midsection, and a crease i is carved in the tip so as to form a triangular shape with the crease g. , if the base paper material is thin, these folds, i, are unnecessary.

In Fig. 1, 17 is the glue allowance, 18, 19, 20.21 are the four peripheral side walls 22, 23, 24, 25 that constitute the box body 1.
is a bottom plate flap connected to each side wall via a fold j.

The bottom plate itself can be assembled by attaching it with tape or stapling.

Next, an example of assembly will be explained.

First, one of the opposing lid pieces 2 and 3 of the box body 1 in the state shown in FIG. 2 is folded inward as shown in FIGS. 3 and 4 to overlap each other, and the handle pieces 8. is made to stand upward to form a handle.

Next, as shown in FIG. 5, the other opposing lid pieces 4 and 5 are bent at their respective creases, and the lid piece insertion groove 10 is inserted from the leading edge thereof.
11, fold the fold line i5g as shown in FIG. 6, and insert the insertion tongue piece 12 into the insertion groove 14.15 to pack it.

When not in use or as a packaging material, when shipping, the lid pieces 2 and 3 are overlapped without raising the handle pieces 8 and 9 from the state shown in Figure 2, and the other lid pieces 4 and 5 are folded so that they overlap. After that, insert the insertion tongue 12 into the insertion groove 14.1 as shown in FIG.
5, the handle part does not get in the way and the lid plate becomes a flat surface, making it convenient for stacking and other handling.

According to the packaging box of the present invention, one opposing lid piece 2.3 is pressed by the other opposing lid piece 4, 5, and the lid pieces 4, 5 are inserted into the lid piece insertion grooves 10, 11. In addition, the insertion tongues 12 formed at the ends of both sides of the lid pieces 4 and 5 are inserted into the insertion grooves 14.15, and the locking claws 13 of the insertion tongues 12 are inserted into the insertion grooves 14.15. Since it is locked to the edge, there is no risk that the entire lid plate will lift up, and even if the item to be packed is heavy, the box body will not hang down from the handle.

Further, as is clear from the developed view in Figure 1, it has the advantage that it can be manufactured from base paper material without any waste, and the lid plate is easy to assemble and is sturdy.
