Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a packaging device that can be used for packaging objects that have a complex shape and require protection for attached components, such as the chassis of electronic equipment. It is something.

Conventional configurations and their problems In general, when packaging articles with complex configurations such as chassis for electronic equipment, etc., conventionally,
A packaging device as shown in FIG. 1 is used.
This is done by first inserting a bottom cushioning material 2 made of styrofoam into a packaging box 1 made of corrugated paper, etc., then inserting a chassis 3 vertically, and then inserting a styrofoam cushioning material 4 on top of it. , has a lid.

However, in such conventional products, since the cushioning materials 2 and 4 are made of styrofoam or the like, the wall thickness must be greater than a certain value in relation to strength, making it difficult to store the packaged items 3 in the packaging box 1. There were problems such as the quantity was reduced, packaging material costs and transportation costs were high, and it was difficult to dispose of waste materials after unpacking.

Purpose of the invention The present invention eliminates these conventional drawbacks, and provides a packaging device that has a simple configuration, can improve the efficiency of packaging and transportation, and can also solve the problem of waste disposal. The purpose is to

Structure of the invention In the invention, first valley fold lines and first mountain fold lines are provided in parallel on both sides of paperboard such as corrugated board. A first notch is provided in the side edge perpendicular to the first valley fold line in parallel with the side edge, a second valley fold line is provided at both ends of the first cut, and by bending these valley fold lines, the first cut is made. The cut portion is made to protrude in an L-shape so that the end edge touches the chassis, etc. Further, two parallel second cuts are provided in the center of the first valley fold line, and two parallel second cuts are provided between the first valley fold lines in a direction perpendicular to the first valley fold line.
A third valley fold line is provided outwardly from the valley fold line of the notch, and a fourth valley fold line is provided at the inner edge of this notch, and a second mountain fold line is provided at the outer edge, and these valley fold lines and mountain fold lines are provided. By bending paperboard such as corrugated cardboard along the line, only the center notch at the fold line is lifted up from the bottom and folded, and the edge of the chassis, etc. is lifted and supported and placed on the back of the chassis, etc. I try to protect the parts.

Also, approximately L is perpendicular to the center of the first mountain fold line.
Provide a letter-shaped hole.

On the other hand, separate from this, a valley fold line is provided parallel to the side edge of paperboard such as corrugated paper, and both ends of the bent part bent along this valley fold line fit into the above-mentioned approximately L-shaped hole. An L-shaped locking part is provided to hold the chassis, etc., and a plurality of notches are provided on the side edge of this bent part to fit the lead wires, etc. of the packaged item to protect it. I'll do what I do.

With this configuration, the same protective effect as paperboard can be achieved without the need for thick walls such as styrofoam, and the storage capacity can be increased.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, as shown in FIG. 2, a first valley fold line 12 for valley folding and a first mountain fold line 1 for mountain folding are formed at both ends of a paperboard 11 made of corrugated paper or the like that serves as the fixed part a.
3 are provided in parallel. A first notch 14 is provided near the side edge perpendicular to this valley fold line 12 and parallel to this side edge, and a second valley fold line 26 is provided at both ends of the notch 14 parallel to the valley fold line 12 and reaching the side edge. will be established. Further, in the center of the valley fold line 12, two parallel second cuts 1 are made orthogonal to the valley fold line 12.
5 are provided, and a third valley fold line 16 is provided between the cuts 15, perpendicular to the cuts 15 and slightly shifted outward from the valley fold line 12. And, Taniori line 1
A fourth valley fold line 17 located at the inner end of the cut 15 and a second mountain fold line 18 located at the outer end are provided so that the inside of the cut 15 is bent in an L-shape with the cut 6 as the center. Further, in the center of the mountain fold line 13, a substantially L-shaped hole 19 is provided which is perpendicular to the mountain fold line 13.

After doing this, when the paperboard 11 made of corrugated paper or the like is folded along each fold line, a fixing part a is formed as shown in FIG. 3. At this time, since the valley fold line 10 is misaligned at the center notch 15, it lifts up from the bottom of the paperboard 11, and both ends of the chassis are cut in order to protect the parts placed on the bottom of the chassis. Lifting and supporting protrusion 2
0 is formed. Further, a portion of the notch 14 provided parallel to the side edge becomes an L-shaped protrusion 21, and serves as a support portion for supporting the edge portion of the chassis or the like.

On the other hand, as shown in FIG.
3 and bend it into an L shape along this. Approximately L-shaped holes 1 of the fixing part a are provided at both ends of the bent part.
9 is provided with an L-shaped locking portion 24 that fits into the
A plurality of inverted Ω-shaped notches 25 are provided on the side edge of the bent portion on the side where the locking portion 24 is provided to form a protection portion b.

Then, as shown in FIG. 5, a packaged object c such as a chassis for an electronic device is placed on the fixing part a, and the fixing part a is formed into a U-shape along each fold line as shown in FIG. Then, L-shaped locking parts 24 are provided at both ends of the protective part b as shown in FIG.
Insert the wires, etc. of the chassis of the packaged item into the inverted Ω-shaped notch 25 to protect them from the main body, and as shown in Figure 6, the chassis, etc. The object to be packaged c is wrapped so as to be sandwiched between the objects, and the object is inserted into a box-shaped partition provided in a packaging box to be packed.

Effects of the invention As described above, according to the invention, an object to be packaged, such as a paper towel, is sandwiched between the securing part and the protective part, which are formed by folding lines and cuts in a paperboard such as cardboard, and is then stored in a packaging box. This eliminates the need for thick walls unlike conventional cushioning materials made of styrofoam, etc., and the storage capacity can therefore be increased. In addition, the material used for the cushioning material is paper, which makes it easy to incinerate and recycle waste materials after unpacking.
