Description

[Detailed Description of the Invention] This invention relates to a packaging box in which an outer box made of, for example, a corrugated board and a buffer plate as an inner part are arranged in series.

Conventionally, in packaging boxes for electrical products, etc., the outer box and buffer plates for interior parts were manufactured separately, and the buffer plates were inserted into the outer box during packaging.

Therefore, it is necessary to put a buffer plate into the outer box during packaging, and there are many parts in the stored state, which requires time and effort to manage.

This invention solves these drawbacks and also aims to improve the strength of the entire box after packaging.One embodiment of the packaging box of this invention will be described below.

That is, in the figure, 1 is an outer box, 2 is a buffer cross frame for storing interior parts, 3a, 3b, and 3C are face walls forming the outer peripheral wall of the outer box 1, and 4 is two walls 3a, 3 on both sides of these three walls.
A series of joints 5 are formed on the outside of c; 5 is a series of buffer plates extending from the joints 4° 4 and partitioning the interior parts in a predetermined folded state during assembly; 6 is a series of buffer plates formed at the upper edge of each buffer plate 5; Combination grooves cut downward, 7 are respective seams 4 of the first bent plate A configured as shown in FIG.
, 4 is fixed in an overlapping state in the assembled state and forms the remaining outer peripheral wall of the outer box; 8 and 9 are a bottom plate and a lid plate provided in series on both sides of this fourth wall 7; 10 is this bottom plate. 8 and a series of insertion flaps provided on the outside of the lid plate 9 together form a second folding plate B shown in FIG.

Reference numeral 11 denotes a cross-frame forming plate having a similar combination groove 12 in one half thereof, which is fitted into the combination groove 6 provided in each buffer plate 5 of the first folded plate A, and 13 denotes a first and second folded plate. bent plate A,
Fig. 1 shows a stitching wire for joining B to the condition of Fig. 1;

In summary, the packaging box of the present invention has three parts that form the outer peripheral wall of the outer box.
Face wall 3a*-3bt 3c and joint allowance 4 on both sides,
4 and a buffer plate 5.5 extending from these, a fourth bent plate A that forms the remaining outer peripheral wall of the outer box.
A bottom plate 8 and its insertion flap 1 are located on both sides of the face wall 7.
0 and a second one having a cover plate 9 and its insertion flap 10
The bent plate B and the stitching wire 1 are connected as shown in Fig.
3 to form an outer box and a buffer plate inside the outer box, and by combining each of these buffer plates with the parallel cross frame forming plate 11, a buffer parallel cross frame for parts storage is formed within the outer box. This is what has become.

As described above, in the packaging box of this invention, the buffer plate of the inner part is constructed in series with the outer box, so the compressive strength of the box as a whole is strong in the assembled state, thus eliminating deformation of the packaging box during transportation and storage. In addition, the number of parts used can be reduced, making assembly easier and easier to store.

[Brief explanation of the drawing]

The figures show one embodiment of the packaging box of this invention. Figure 1 is a perspective view with the lid open, Figure 2 is a plan view of the folding plate shown in Figure 1, and Figure 3 is the second folded plate. FIG. 4 is a plan view of the bent plate, and FIG. 4 is a plan view of the parallel cross frame forming plate. In the figure, 1 is the outer box, 2 is the buffer frame for storing parts, 3a,
3b and 3c are three walls of the outer box, 4 is a joint, 5 is a buffer plate, 6 is a combination groove thereof, T is a fourth wall, 8 is a bottom plate, 9 is a cover plate, 11 is a cross frame forming plate, 12 is a In the combined grooves, A indicates the first folded plate and B indicates the second folded plate.

Claims (1)

[Scope of utility model registration request] A front wall and both side walls that form the outer peripheral wall of the outer box, a seam connected to each side wall, and a combination groove that is continuous in the longitudinal direction on the other side of this seam and into which the parallel girder frame forming plate is fitted. A first bent plate having a series of buffer plates of interior components provided with a buffer plate, a rear wall which is the remaining outer peripheral wall of the outer box, a bottom plate and a lid that are continuous in the longitudinal direction on both sides of this rear wall. a second folding plate having a series of plates, the bottom plate of the second folding plate being on the bottom of the first folding plate, and the bottom plate of the second folding plate being on the rear side of the outer peripheral wall of the first folding plate. A packaging box characterized in that both folding plates are overlapped and fixed in such a manner that the rear wall of the second folding plate is positioned, and a cross frame for storing parts is formed inside.
