[0001]

FIELD OF THE INVENTION The present invention relates to improvements in travel trunks.

[0002]

2. Description of the Related Art A conventional travel trunk is made of a box-shaped synthetic resin having a front surface 110, a main body upper surface 120, one side main body side surface 130, another side main body side surface 140, and a main body bottom surface 150, as shown in FIG. Trunk body 100 and back 21
0, the lid upper surface 220, the one side lid side surface 230, the other side lid side surface 240, and the lid bottom surface 250, and the lid body 200 made of a synthetic resin in the shape of a box, the opening sides of both the main body bottom surface 150 and the lid bottom surface 250. Most commonly, the parts 151 and 251 are hinged by hinges 3 and 3.

As the synthetic resin material, a material having a large rigidity such as ABS resin is used. To further increase the rigidity, the trunk main body 10 is formed as shown in FIG.
0 and the lid 200 are provided at their opening edges with metal frames 160 and 260 made of aluminum or the like.

In FIG. 9, reference numeral 1 denotes a lock body for removably connecting and locking the trunk body 100 and the lid body 200, and 2 and 2 denote handles.

[0005]

However, the biggest problem of the above-mentioned conventional travel trunk is that the material such as synthetic resin is reused as a resource when the unnecessary travel trunk is discarded. There is nothing.

That is, synthetic resins such as ABS resins and nylon resins, which are called engineering plastics, in which the cross-linking state of molecules is improved under a strict temperature condition with a catalyst have great rigidity, but are discarded after use. There is a problem in that it is difficult to crush a product that is regarded as a product. In addition, it is well known that, even if they are temporarily crushed, if these engineering plastics are heated again and melted and used as molding materials, they tend not to retain their original properties. However, the material itself has a property that is not suitable for recycling, and it is very troublesome to remove foreign materials such as the metal frames 160 and 260 attached to the opening edge. It causes trouble.

If the discarded material is incinerated without being used as a resource again, the synthetic resin material may generate harmful gas and may cause an abnormally high temperature to damage the incinerator. Not only is it very bulky even after disposal,
It has a problem that it is not decomposed naturally.

[0008] Therefore, the present inventor replaced the engineering plastic with a synthetic resin material having a small rigidity which can be easily recycled, and provided a travel trunk in which the opening edge frames 160 and 260 which are the most difficult to remove are omitted. Although manufacturing was tried, as shown in FIG. 8, when the force of arrow P is applied from above by placing it on the floor F and sitting down, the joint between the trunk body 100 and the lid body 200 is the same point in FIG. It has been found that there is a problem that not only the appearance is bad, but also the stored items may stick out or fall off because of the curved shape as shown by the chain line to open a gap in the opening joint portion.

Therefore, the present invention has been made to solve the above-mentioned problems, and uses a synthetic resin that has a small rigidity but is easy to reuse, and does not use a metal frame for reinforcing the opening edge of the trunk body. An object of the present invention is to provide a travel trunk in which a gap is less likely to occur at the joint between the lid and the lid.

Another object of the present invention is to simplify the manufacturing and reduce the weight by omitting the metal frame for reinforcing the opening edge. It is intended to be provided.

[0011]

In order to solve the above-mentioned problems, the structure of the present invention, which has the above-mentioned claims as its gist, has a front surface 110, a main body upper surface 120, and one side main body side surface 130.
