Description

[Detailed Description of the Invention] This invention relates to a cushioning material for packing electrical appliances, which is used when packing relatively small and simple electrical appliances, such as ventilation fans, in an outer box.

For example, conventional packaging for ventilation fans consists of a lower cushioning material that has a flange that receives the back of the front cover of the ventilation fan, a storage recess in the center that accommodates the outer box of the ventilation fan, and a cushioning material that fits the front of the front cover of the ventilation fan. This is done by wrapping the ventilation fan in an upper cushioning material that has a flat plate that can be brought into contact with the ventilation fan, and placing the cushioning material together with the cushioning material in an outer box made of corrugated paper or the like.

The power cord for the ventilation fan was properly placed inside the outer box.

However, when automating packaging, if the power cord is handled arbitrarily as in the past, the power cord may get in the way and the packaging machine may not operate properly.

Therefore, the purpose of the present invention is to provide a cushioning material for packaging electrical appliances that can easily and uniquely fix power cords and can be easily adapted to automation (mechanization) of packaging. .

Next, the configuration of the present invention will be specifically explained based on an embodiment shown in the drawings.

The cushioning material as an application example of the present invention shown in the drawings is of a type in which the upper and lower parts are separated, and is used for packaging a ventilation fan.

That is, a set of cushioning materials includes an upper cushioning material 1 and a lower cushioning material 2, and the entire material is corrugated paper or cardboard having appropriate rigidity.

The upper cushioning material 1 is approximately H-shaped with a flat plate part 3B extending horizontally in the center of side plate parts 3A forming both sides.
The front surface of the front cover 4A of the ventilation fan 4 can be held in contact with the front cover 4A.

Each side plate portion 3A on both sides of the upper cushioning material 1 has an upper end that is connected to the flat plate portion 3.
It protrudes from B, and as shown in FIG. 4, the upper end abuts against the inner surface of the outer box 5 in the packed state to form a buffer space S1 between the flat plate part 3 and the outer box 5.

Two retaining protrusions 6 are provided at the lower end of each side plate portion 3A.
is provided in a protruding manner so that it can be easily assembled to the lower cushioning material 2, which will be described later.

As shown in FIG. 1, a band-shaped cord retainer 7 is formed on the upper surface of the flat plate portion 3B of the upper cushioning material 1 along one free end thereof.

The cord retainer 7 has a plurality of locking teeth 8 facing each other on both sides in the longitudinal direction, and is cut out with one side left as a bent portion 9.

Therefore, when the cord retainer 7 is folded up at the bending part 9 as shown in FIG. The retainer 7 can be curved and fixed by the teeth 8 as shown in FIG. 3 to form a loop of an appropriate size.

That is, the power cords 11 of the ventilation fan 4 can be folded back and bundled together, and the bundled power cords 11 can be bound and held by the loop provided by the cord retainer 7.

In addition, the reference numeral 12 in the figure is a cord escape part for routing the power cord 11 of the ventilation fan 4 housed in the lower cushioning material 2 side to the cord retainer 7 of the flat plate part 3B. A cutout is formed on the side edge of.

The lower cushioning material 2 is formed into a substantially box shape as shown in the drawing,
A flange portion 13 protrudes in the left-right direction at the upper end of the storage recess S2 that accommodates the outer box portion of the central ventilation fan 4.

The dimension between the flange portions 13 of the lower cushioning material 2 is approximately equal to the dimension between the facing walls in one direction of the outer box 5 for packaging.

The front cover 4 of the ventilation fan 4 is attached to this flange portion 13.
The ventilation fan 4 is housed in the lower cushioning material 2 by receiving the back part of A.

In contrast to the lower cushioning material 2 containing the ventilation fan 4, the above-mentioned upper cushioning material 1 has a flat plate portion 3B that serves as the front cover 4A of the ventilation fan 4.
They are assembled so that they come into contact with the front surface of the

The upper cushioning material 1 and the lower cushioning material 2 are combined by fitting, and each side plate of the upper cushioning material 1 is inserted into each of the four retaining holes 14 formed in the flange portion 13 of the lower cushioning material 2. This is done by fitting the engagement protrusions 6 of 3A together.

Packing of the ventilation fan 4 into the outer box 5 is completed by putting the combined cushioning material into the outer box 5 as described above, closing the lid of the outer box 5, and wrapping it with a band or the like.

Such packaging is carried out manually or with a packaging machine, but this cushioning material can be used for packaging without any problem in either case.

In other words, when automatically packing with a packing machine, not only is it impossible to properly dispose of the power cord 11, but also
If the power cord 11 is not properly handled, troubles will occur such as the power cord 11 getting in the way and not being able to be packaged. However, according to the cushioning material with the above-mentioned structure, the power cord 11 can be placed inside the cushioning material with a cord retainer. Since the power cord 7 can be uniquely held, troubles in packaging caused by the power cord 11 are virtually eliminated.

Of course, in addition to the operational advantages of such packaging, there is also the advantage that the power cords 11 are well organized and the packaging condition is good.

Further, as explained in the embodiments, the present invention can be applied to electrical appliances other than ventilation fans as long as a separate type can be adopted.

As is clear from the above description of the embodiments, the cushioning material for packing electrical appliances of the present invention wraps the electrical appliance in the upper and lower cushioning materials, and the upper part especially has a band-shaped cord retainer made of a cutout. Since it is integrally formed, the power cord of the electrical appliance can be easily held at a specific position on the cushioning material.

Therefore, even when automatic packaging is carried out using a packaging machine, it is possible to prevent packaging troubles such as fluctuations in the power cord as much as possible.
