Abstract

(57) [Summary] [Purpose] To provide a packaging case that allows easy packaging of products and has a great cushioning effect against external shocks and vibrations. [Structure] A bag-shaped elastic body 3 having an air injection port 2 is arranged inside a case body 1 in which a product is stored, and the elastic body 3 is inflated by air A injected from the air injection port 2. The product is fixed in the case body 1 by the expanded elastic body 3. The elastic body covers the entire outer surface of the product regardless of the shape of the product and protects the product from impacts from all directions, so that the cushioning effect is great.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging case provided with a cushioning material for protecting products such as electric equipment from vibration and shock during transportation.

[0002]

[Prior Art]

 Conventionally, when packaging products such as electric devices in a packaging case for transportation, the products packaged in the packaging case are subject to shocks when the packaging case is loaded into or unloaded from the vehicle, and vibration during transportation may occur. A cushioning material is provided between the product and the inner wall of the packaging case to protect the product from shock and vibration so that it will not be received. As this type of cushioning material, styrofoam moldings, chips, plastic sheets with a large number of air-filled protrusions, and die-cut corrugated cardboard are used. However, plastic cushioning materials such as styrofoam and polyethylene sheets have environmental problems such as incineration at the time of disposal, whereas corrugated cardboard has little cushioning effect. Also, for cushioning materials such as Styrofoam molded products and corrugated cardboard die-cut products, the shape is determined according to the size of the product, and the size of the corresponding packaging case is also determined. Since multiple types of packaging cases with different sizes are required, the cost of packaging cases due to mass production cannot be reduced, and the efficiency of packaging work is also reduced.

[0003]

[Problems to be solved by the device]

 The present invention has been made to solve the above problems, and an object thereof is to provide a packing case that can easily pack a product and has a great cushioning effect against external shocks and vibrations.

[0004]

[Means for Solving the Problems] A packaging case according to the present invention comprises a case body in which a product is stored, a lid body attached to the case body, and an air injection port arranged inside the case body. And a bag-shaped elastic body.

[0005]

[Action]

 According to the above configuration, the product can be stored in the main body case, the elastic body is expanded by the air injected from the air injection port, and the expanded elastic body can fix the product in the case main body. Therefore, the air cushion of this elastic body can protect the product from external shocks and vibrations. Further, the elastic body covers the entire outer surface of the product so as to wrap it, and the product is protected against impact from any direction, so that the cushioning effect is great.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a packaging case according to the present invention. In the figure, for example, a case body 1 made of corrugated cardboard is integrally formed with an openable / closable lid body 1a, and an air inlet 2 of a bag-shaped elastic body 3 is projected from a side surface of the body case 1. ing. The elastic body 3 is, for example, a rubber bag-shaped elastic body, and is provided with an air inlet 2 communicating with the inside of the elastic body. The elastic body 3 is disposed inside the case body 1 and the air inlet 2 is provided. It expands with air A injected from.

To explain the packing operation in the packing case having the above structure, first, as shown in FIG. 2A, the product 5 to be packed is placed at a predetermined position of the elastic body 3 arranged inside the case body 1. Place it. Next, as shown in FIG. 2B, the end 5a of the elastic body 3 is wrapped around the product 5 to cover the product 5, and the lid 1a of the case body 1 is closed and fixed to the case body 1. Then, when the air A is injected from the air inlet 2, the elastic body 3 expanded by the air A is brought into close contact with the entire outer surface of the product 5 as shown in FIG. Fix it. Then, for example, a plug (not shown) is attached to seal the air inlet 2, and the packing operation of the packing case is completed. On the other hand, at the time of unpacking the packaging case, the product 5 can be taken out by removing the plug of the air inlet 2, releasing the air of the elastic body 3, and opening the lid 1a.

In this way, the expanded elastic body 3 adheres to the outer surface of the product 5 regardless of the size and shape of the product 5, and the product 5 is fixed by the elastic body 3, so that the packing case can be loaded or unloaded. Even if the product is sometimes shocked or vibrated during transportation, the air cushion of the elastic body 3 protects the product 5 from the shock or vibration. Therefore, it is not necessary to prepare a packaging case having a different size for each product 5, and it is possible to reduce the cost and improve the packaging efficiency by sharing the packaging case. Further, the elastic body 3 covers the entire outer surface of the product 5 so as to wrap it and protects the product 5 from impacts from all directions, so that the cushioning effect is great. Further, it goes without saying that the same packaging case can be used any number of times if the case body 1 has a certain degree of rigidity.

In addition, in the above-mentioned embodiment, the air inlet 2 is provided in one bag-shaped elastic body 3. However, as shown in FIG. 3, the elastic body 3 has a plurality of bag-shaped elastic bodies. The body 3b may be connected by a connecting pipe 3c. Further, the air inlet 2 does not necessarily have to protrude from the main body case 1. As shown in FIG. 4, before the lid 1a is closed, air A is injected from the air inlet 2 to expand the elastic body 3. The lid 1a may be closed after the air inlet 2 is sealed.

[0010]

[Effect of the device]

 As described above, according to the present invention, by packaging the product in the packaging case through the elastic body that can be expanded and contracted, it is possible to provide the packaging case that is easy to package and has a great cushioning effect against external shock and vibration. can do.
