Description

[Detailed Description of the Invention] The present invention relates to a packaging device for electric washing machines, refrigerators, etc.

Conventionally, one of the unique market demands for vertically elongated products such as electric washing machines and refrigerators has been to reduce the number of dents that are relatively common at some of the body corners.

The reason for this is that during loading and unloading work on the truck bed, etc., the central part of the vertically long product is first attached to the loading bed, so if the product is mixed with small items, etc., the corners of the central part of the product may dents are likely to occur.

As a countermeasure to this problem, it is easy to think of adding another material such as inserting a cushioning material between the product and the outer box, but this increases the cost and requires more work in the cardboard manufacturing process and packaging line. The drawback was that it was difficult.

Furthermore, as shown in FIG. 1, the cause of the dents caused by the product 3 on the loading platform 2 of the truck 1 is due to the sharp vibration of the product due to sudden braking when the product is mixed with the small product 4. The middle part of the large product 3 collides with the container, causing a dent, or the middle part of the product 3 hits the corner of the loading platform 2 when loading and unloading the product, causing a dent.

As a countermeasure to this problem, a corner protection material 7 was inserted into the vertical ridge 6 of the product body 5 as shown in Fig. 2, but such a measure would increase the cost of the material and complicate the work. However, it has the disadvantage of being difficult to repack.

The present invention provides a packaging device that is inexpensive and effectively prevents corner dents, in order to eliminate the drawbacks of the conventional example.

Hereinafter, embodiments will be described in detail with reference to the drawings.

Figures 3 to 5 show one embodiment of the present invention.
The product main body 8 is placed on a lower cushioning body 9 made of styrofoam or the like, and its upper part is held by an upper cushioning body 10 to be cushioned and fixed.

An outer box 11 is inserted into the bottom box 12 to cover this, and is wound and fixed with a PP band 13. In this configuration, the intermediate portions of the vertical ridges 8a (four corners) of the product body 8 are cushioned. There is no material, so it is extremely vulnerable to dents.

Therefore, in the present invention, as shown in Fig. 4a, the outer box 1
Vertical ridge portion 11a of 1 -B'=C'
Then, as shown in FIG. 5, bend it inward around B to form a bent part.

Furthermore, in order to prevent dust from entering through the notches A and A' and to hold the bent part, the new curved part touches part of the corner of the upper and lower shock absorbers 9 and 10 that abuts the upper and lower notches A and A'. Pit parts 9a and 10a are bored, and the upper and lower ends of the bent parts are brought into contact with each other.

According to the present invention configured as above, the upper and lower shock absorbers 9,
In order to protect the fragile parts of the vertical ridges 8a (four corners) of the product body between 10 and 10, bends are provided on the vertical ridges 11a (four corners) of the outer box 11, so that the product does not receive shock. When received, the bent part of the outer box 11 acts as a protrusion to protect the product from impact, and prevents dents on the product body. Part 9a, 1
Since it is in contact with 0a, it not only prevents the intrusion of dust, but also reduces the impact at the meat stealing portions 9a and 10a, thereby increasing the effect of preventing dents.

Also, as shown in Fig. 4, the meat stealing parts 9a, 10
Groove portion 9b in a.

10b is integrally drilled and the upper and lower ends of the bent portion are inserted into the grooves 9b and 10b, the bent portion can be held more perfectly and the effect will be increased.

In addition, in order to strengthen the bending part of the outer box 11, use of reinforced core base paper and corrugated board with less resilience of B flute (B tier of double-sided corrugated cardboard) or less is used to further prevent dents. The effect can be increased.
