JPS5836713Y2 - packaging box for light bulbs - Google Patents

Description

[Detailed description of the invention] The present invention relates to a packaging box suitable for transporting and storing light bulbs, especially large light bulbs.In particular, the present invention is a packaging box suitable for transporting and storing light bulbs, especially large light bulbs. The light bulb can be stored and fixed in a simple sleeve shape and used for transportation and storage by simply bending the sleeve, which greatly reduces the amount of materials used such as corrugated poles and increases transportation and storage efficiency. This relates to packaging boxes for light bulbs.

Hereinafter, the present invention will be specifically explained with reference to illustrated embodiments.

FIG. 1 is a developed view showing an embodiment of the present invention.
, rear plate 2, side plate 3, front plate 4, and side plate 5 on fold line 6.7,
8.9, the upper part of the front plate 4 is divided by a fold line 10 as a restraining plate 11, and furthermore, triangular flaps 1 are provided on both the left and right edges of the restraining plate 11, and are partitioned on the side plates 3 and 5.
2.12, and then carve a cutting line 13.13 perpendicular to the fold lines 8 and 9 on the front plate, and also cut both cutting lines 13.13.
A folding piece 15 is formed by cutting a folding line 14 connecting both ends of the side plate 3 and the lower edge of the side plates 3, 5 and the front plate 4.

On the other hand, a fitting plate 17 is formed on the rear plate 2, which is connected to the rear plate 2 by a fold line 16, and a support piece 18 is provided approximately in the center of the fitting plate 17, which protrudes from the rear plate 2. A stop hole 19 is drilled in each case.

The present invention has the above-described structure, and is made into an endless shape via the connecting piece 1, and is also folded into a flat plate shape as shown in FIG. 2 for use.

Next, when using this, first make it into a square tube as shown in FIG.
, 5, and the tips of the flaps 12.12 are inserted into the locking holes 19.19 and locked, thereby fixing the box body.

Furthermore, the folded pieces 15.15 are attached to the folded lines 8, 14.14 and 9,
14. Fold inward through 14 and lift the fitting plate 17 horizontally to form the fitting hole 20 (see Figure 4).
.

The packaging box for light bulbs of the present invention is assembled as described above, and the light bulbs are stored in the fitting hole formed by holding the fitting plate 17 horizontally, as shown in the cross section of FIG. 20 and is supported and fixed by the support piece 18, and furthermore, the bulb body is fixed by the rear plate 2, both side plates 3.5 and the holding plate 11 while being placed on the folded piece 15. It can be transported and stored in sufficient condition.

Alternatively, the locking hole 19 may be omitted when fixing the restraining plate 11, and the holding plate 11 may be adhesively fixed to the side plates 3 and 5 using adhesive tape or the like.

As mentioned above, the present invention is a packaging box that can be used to package light bulbs with extremely simple assembly from a simple rectangular cylindrical box without a lid plate and bottom plate. The efficiency can be increased by combining them in the following manner.
