Description

[Detailed Description of the Invention] This invention relates to a packaging device for preventing soiling and damage to ventilation fans during storage or transportation.

Conventionally, in this type of packaging equipment for ventilation fans, a buffer is placed in the space between the outer box and the ventilation fan in order to prevent the ventilation fan housed in the outer box from moving and being damaged during transportation. The shock absorber used was a molded product made of foamed resin or a cardboard material cut into appropriate dimensions and then assembled into a predetermined shape by gluing or the like.

However, conventional cushioning bodies created in this way, for example, those made of foamed resin, may cause pollution when disposed of after use, and those made of cardboard material by cutting and gluing them into a predetermined shape are difficult to manufacture. There were drawbacks such as high cost.

In addition, in recent years, mass production factories have begun to adopt automatic packaging equipment to increase packaging productivity, but when performing automatic packaging, it is necessary to integrate ventilation fans and cushioning bodies. However, it is necessary to secure the ventilation fan and the buffer with tape or string, which has the disadvantage of significantly reducing work efficiency.

The purpose of this invention is to improve the above-mentioned drawbacks.The rear holder that supports the rear part of the ventilation fan is formed by bending a paper strip into an annular shape, which is an extremely simple structure.
To provide a packaging device which has a low floor and can securely hold a ventilation fan.

An embodiment of this invention will be described below with reference to FIGS. 1 to 6.

Figure 1 is a developed view of the outer box, Figure 2 is a perspective view of the rear holder, Figure 3 is a perspective view of the front holder, Figure 4 is a developed view of the front holder, and Figure 5 is integrated with the holder. FIG. 6 is a sectional view of the front holder showing the ventilation fan housed in the outer box.

In the figure, 1 is an outer box made of paper board material such as cardboard, 1a is a fold line indicated by a dotted line, 1b is a cut line,
2 is rear holder 2, and this rear holder 2 has slit 2.
a.

Bottom plate 2c1 side plate 2d formed by bending in contact with 2b,
It consists of 2e1 and 2f upper plates, and is formed by doubly bonding them together.

3 indicates a front holder formed by bending a paper strip 3a such as cardboard into an annular shape; 4 a , 4 b t 4
c t 4 d are mutually perpendicular support plates, 5a, 5
b, 5C25d are these support plates 4a-4b, 4b-4
c, a direct connection plate connecting 4c4ci, 4ct 4d, 6a.

6bt6ct6d are the above-mentioned support plates 4a, 4b, and 4c.

The front holder 3 is formed into an octagon by bending the paper strip 3a by 45 degrees along the fold lines 7 and joining the ends to each other. There is.

Next, as shown in FIG. 5, the ventilation fan 8 whose rear part 8a is supported by the rear holder 2 is placed on the flattened outer box 1, and the corner 8c of the front part 8b of the ventilation fan 8 is Notches 6 formed in the support plates 4a to 4d of the section holder 3
A to 6d are fitted and supported.

As described above, the rear holder 2 and the front holder 3 are held integrally by the ventilation fan 8.

Next, an automatic packaging device (not shown) bends the outer box 1 from the fold line 1a in a predetermined order to form a box shape with the ventilation fan 8 integrated with the front and rear holders 2 and 3 accommodated therein. Seal with adhesive, etc.

That is, as shown in FIG. 6, the four corners of the ventilation fan 8 are support plates 4a and 4b.

4 c t 4 d, and the connecting plates 5a, 5b, 5c, and 5d, which are integral with the connecting plates 5a, 5b, 5c, and 5d, are in contact with the inside of the outer box 1, so that sideward movement is restricted, and the elasticity of the support plates It will be buffered.

As described above, in this invention, since all the holders are made of paper material, there is no risk of causing pollution when disposed of after use.

Furthermore, since it can be formed by bending a single strip of material, it is possible to reduce material costs and assembly costs, and less space is required for storing materials before assembly and after use.

Furthermore, since the ventilation fan can be assembled together with the holder on the flat outer box, automatic packaging becomes easy and packaging costs can be reduced.
