Description

[Detailed Description of the Invention] This invention relates to a packaging device for electronic musical instruments and the like.

Items to be packed, such as electronic musical instruments and pianos, are delicate and often made of wood, and their functionality is likely to be impaired by environmental conditions such as humidity.

For this reason, packaging, especially packaging for shipping by sea, is exposed to large temperature differences, high humidity, and a salty atmosphere for long periods of time during transportation, so the packaging outer container must be moisture-resistant. It is necessary to provide a sufficient hermetic covering of the packaged items.

Conventionally, this type of export packaging generally involves covering the packaged item with a highly moisture-resistant vinyl cover, filling it with moisture-absorbing material, sealing it, and then packaging it in a wooden frame or cardboard box. However, in the former case, the work efficiency of packing is poor due to the nailing work involved, and unpacking is also time-consuming.

Moreover, not only is there a risk of incurring costs due to the recent rise in the price of wood, but also the overall weight of the packaging increases because the wooden frame itself is heavy.

As a result, there were many drawbacks, such as making cargo handling laborious and generally rough, as well as increasing transportation costs.

On the other hand, in the latter case, open the top lid of the cardboard box,
Since it is necessary to lift the item to be packed and drop it into the cardboard box from above, this does not pose a problem when storing small and light weight items, but it does not pose a problem when storing large and heavy items such as musical instruments. When storing items, there are inconveniences such as the work of lifting the items to be packed is difficult and there is a risk that the items to be packed may be damaged, and the work is dangerous.

In view of the above points, this idea was developed by sealing the item to be packed with a plastic bag, etc., placing it in a packaging container such as a cardboard container, and tightly surrounding the outer periphery of the packaging container with shrink film. The purpose is to provide a packaging device that facilitates unpacking work and is highly moisture resistant and heat insulating.

An embodiment of this invention will be described in detail below with reference to the drawings.

Fig. 1 is an exploded view showing an example of a packaging container when the item to be packed is an electronic musical instrument. 1 and
flat side plates 3 disposed on both left and right sides of the electronic musical instrument C;
3, and the shallow box-shaped Tenju 4 placed on the top of the electronic musical instrument C.
and a rectangular cylindrical body frame 5 that surrounds the side circumference of the electronic musical instrument C.
All of these are made of corrugated cardboard.

Further, on the front and rear edges of each of the left and right side plates 3, 3, fiber angles 6 for reinforcing loading pressure are affixed vertically along the edges, and the side plates 3, A horny tube 7 is pasted laterally along the upper and lower edges of the inner surface of each of the tubes 3, and a square paper tube 8 is pasted on the front and rear edges, respectively.

Furthermore, a plurality of square paper tubes 9 are pasted on the inner side of the upper bottom surface 4a of the tenju 4 in the front-rear direction.

Next, a packing procedure using the above-mentioned packing machine H will be explained.

First, a plastic bag B is placed over the electronic musical instrument C, which is the item to be packed, and a moisture-absorbing material is placed inside the plastic bag B, and the opening side of the plastic bag B is closed.
hermetically coated.

Then, the base 1 is placed on the skid S, and the lower end of the electronic musical instrument C, which is hermetically covered with the plastic bag B, is inserted into the boat 1.

Once this is completed, the side plates 3.3 are placed on the left and right sides of the electronic musical instrument C, and the lower ends of these are inserted between the sides of the electronic musical instrument C and the upright wall of the ground 1. The left and right sides of the electronic musical instrument C are covered with side plates 3, 3.

Thereafter, Tenju 4 is placed on the top of electronic musical instrument C to cover the top surface of electronic musical instrument C, and the side plates 3, 3 are placed between the upright wall of Tenju 4 and the side surface of electronic musical instrument C.
Fit the upper end of the

Finally, a body frame 5 is fitted to the outside of the side plates 3, 3, and the body frame 5 surrounds the entire side circumference of the electronic musical instrument C.

Then, the electronic musical instrument C is completely surrounded by the packaging container H assembled into a box shape, and the square paper tubes 7 and 8 are placed inside the packaging container H.
and fixed by 9.

Then, as described above, the entire outer periphery of the packaging container H containing the electronic musical instrument C is covered with a polyethylene or polypropylene shrink film (heat-shrinkable film) F, and then the shrink film F is heat-shrinked to form the packaging container H. The packaging container H is hermetically surrounded by the shrink film F, which is tightly attached to the outer periphery.

By sealing and bending the packaging container H with the shrink film F, it is possible to block moisture from entering the packaging container H and protect the items to be packed in the packaging container H along with the plastic bag B from moisture. At the same time, since the shrink film F tightly surrounds the outer periphery of the packaging container H, the rigidity of the packaging container H itself is increased, and the strength of the packaging container H, especially the strength against buckling, is increased.

Moreover, according to the packaging container H having the above structure, it is only necessary to store the items to be packed in the shallow box-shaped base 1 and assemble the side plates 3, 4, and the body frame 5, so that it can be used as a normal cardboard box. There is no need to lift the items to be packed as high as possible, and the work is extremely simple and safe, and the items to be packed are less likely to be damaged.

Furthermore, since no tacker nails or the like are used when assembling the packaging container H, no special machinery or tools are required, and packing and unpacking operations can be carried out with great ease.

In addition, the item to be packaged is triple-covered with a moisture-resistant material, a packaging container, and a shrink film, and by interposing the packaging container between the moisture-resistant material and the shrink film, there is no space between the moisture-resistant material and the shrink film. Since a gap is formed that serves as a heat insulating and moisture-resistant air layer, the packaging portion can be further protected in good condition.

As is clear from the above explanation, the packaging device of this invention uses a packaging container made of paper material such as cardboard and composed of a top, bottom, side plates, and a body frame. It can be assembled without nailing, etc., and there is no need to lift the items to be packed high, making the packing process much simpler and easier than with conventional packaging using wooden frames or cardboard boxes, and there is no risk of damage to the items being packed. Not only does it reduce the number of accidents caused by falling, making it safer, but it also makes unpacking easier, and the cost of materials is low, which greatly contributes to cost reduction.

In addition, since the item to be packed is stored in a moisture-resistant H such as a plastic bag, it is surrounded by a packaging container, and the outside of the container is tightly sealed and bent with a shrink film.
Packaged items are double protected from moisture, salt air, and other hazards by using moisture-resistant materials and shrink film.

Moreover, the shrink film not only has the function of sealing the packaged object, but also has the function of reinforcing the packaging container itself by being tightly attached to the outer periphery of the packaging container due to heat shrinkage, making the packaging container more difficult to buckle and making it easier to stack and stack. It also has the advantage of being durable.

Furthermore, since a gap is provided between the moisture-resistant material and the packaging container, and a shrink film is provided around the outer periphery of the packaging container, this gap forms a heat insulating and moisture-resistant air layer to further protect the packaged items. It has many effects such as protection.
