Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo container, and more particularly, to a cargo container using a panel material made of aluminum corrugated cardboard as a panel material.

[0002]

2. Description of the Related Art Conventionally, freight containers have been used for storing and transporting freight. The freight containers that have been conventionally used generally include metal panels made of aluminum or the like and aluminum Was formed by assembling into a square shape via a metal frame.

[0003] As the metal panel conventionally used, a panel formed of a thick metal plate has been used.

[0004]

As described above, since the conventional cargo container uses a thick metal plate as a panel material, the weight of the entire container increases, Inconvenient to transport, and
In the case where the vehicle is mounted on a cargo bed of a lorry or the like, there is a problem that the amount of luggage that can be loaded is reduced due to the limitation of the loading capacity.

[0005] While metal panels made of aluminum or the like are expensive, as described above, the metal panels used in conventional containers are thick metal plates, so that the aluminum panels used are expensive. The amount of metal of
As a result, there is a problem that the manufacturing cost of the container is increased.

Further, for example, in the case of aluminum, a panel having a square of 1 cm has a thermal conductivity of 5000 per second.
Due to high calorie, in a container using aluminum plate as a panel, if the surrounding temperature is high such as in summer, the surrounding temperature will be directly conducted into the container and the temperature inside the container will increase. There is a point. For this reason, when transporting items that need to be frozen or refrigerated, it is necessary to operate a cooler or the like fully in order to suppress a rise in the temperature inside the container. As a result, there is a drawback that power consumption increases.

Accordingly, the present invention provides a cargo which is lightweight and low-cost, has excellent durability, and is capable of suppressing a rise in internal temperature even when the ambient temperature is high. The task is to provide containers.

[0008] Some containers can be mounted on a carrier such as a lorry, in addition to those capable of moving the container itself, and this type is generally called a "rear panel". In the present invention, the cargo container including the rear panel is also referred to as a cargo container.

[0009]

According to a first aspect of the present invention, there is provided a freight container according to the present invention, wherein a front panel, a pair of side panels, and an upper panel are assembled into a substantially rectangular shape using a plurality of frames. A cargo container having a door panel openably and closably mounted on a side facing the front panel, wherein at least the front panel and the pair of side panels are formed of a panel material made of aluminum cardboard. The frame for assembling the front panel, the pair of side panels, and the upper panel into a substantially rectangular shape has a substantially L-shaped side surface and both end portions along a longitudinal direction. And a corner frame provided with an insertion groove for inserting a panel.

In the cargo container according to the present invention, the front panel, the pair of side panels, the upper panel, and the bottom panel are assembled into a substantially rectangular shape using a plurality of frames. A cargo container having a door panel openably and closably mounted on a side facing the front panel, wherein at least the front panel, the pair of side panels, and the bottom panel are made of aluminum cardboard. The frame for assembling the front panel, the pair of side panels, the upper panel, and the bottom panel into a substantially square shape is a long object having a substantially L-shaped side shape. In addition, the corner frame is provided with insertion grooves for inserting panels at both end portions along the longitudinal direction.

As described above, the cargo container of the present invention uses the aluminum corrugated cardboard panel material, and uses the aluminum corrugated cardboard panel material for at least the front panel and the pair of side panels.

Here, aluminum corrugated board is generally
It is composed of a pair of face plates made of a thin aluminum plate and a corrugated core material interposed between the pair of face plates, and a hollow portion is formed between the pair of face plates.

Therefore, when comparing this aluminum corrugated cardboard with an aluminum plate material, if both have the same thickness, the aluminum corrugated cardboard having a hollow portion becomes lighter while the core material is interposed. Therefore, the durability is not remarkably deteriorated.

[0014] In addition, aluminum corrugated cardboard has the advantage of lowering the price because it requires less aluminum to be used than a thick aluminum plate material.

Therefore, in the cargo container of the present invention using the aluminum corrugated cardboard panel material, the weight of the entire cargo container is larger than that of a conventional cargo container using a thick metal plate material as a panel. And the production cost of the freight container can be kept low. As a result, it is easy to carry, and when equipped in a lorry, etc., it is possible to load more luggage, and at the same time, it is possible to keep manufacturing costs low, while having sufficient durability You can get a freight container.

Further, since the aluminum corrugated cardboard having the hollow portion is used as the panel material, unlike the case where the plate material is used as the panel, it is possible to prevent the temperature around the container from being directly transmitted to the inside of the container. Even when the temperature is high, it is possible to suppress a rise in the temperature inside the container as compared with a conventional cargo container.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a cargo container according to the present invention; FIG. 1 is a perspective view showing the cargo container according to the embodiment; FIG. . FIG. 2 is an end view showing the structure of the cargo container 1 of the present embodiment from a plane side.
FIG. 3 is an end view showing the structure of the cargo container 1 of the present embodiment from the rear side.

As shown in the drawing, the cargo container 1 of the present embodiment has a front panel 2, a pair of side panels 3, and an upper panel 4 formed by a corner frame 6 in a substantially rectangular shape. And a door panel 5 is mounted on the side facing the front panel 2 via an end frame 7 so as to be openable and closable.

That is, in the figure, 2 is a front panel, and 3 is a front panel.
Is a pair of side panels. In the present embodiment, the front panel 2 and the pair of side panels 3 are arranged in a plane view with the front panel 2 on the right side by using a corner frame 6 (see FIG. 2). ), Are connected so as to have a substantially U-shape, and in the present embodiment, further, in this embodiment, an end of the pair of side panels 3 facing the side connected to the front panel 2, and a pair of side panels The end frame 7 is attached to the lower end of the panel 3.

The front panel 2 and the pair of side panels 3 in this embodiment are both formed of aluminum corrugated cardboard.

Here, FIG. 4 is a view showing a panel member 8 made of aluminum corrugated cardboard which constitutes the front panel 2 and the pair of side panels 3, and this panel member 8 is made of a pair of aluminum thin plates. 801 and 802, and a core member 803 made of an aluminum thin plate and interposed between the pair of face plates 801 and 802. The core member 803 is formed in a corrugated shape, thereby forming a so-called honeycomb structure.

As described above, the panel material 8 made of aluminum corrugated cardboard is formed by a pair of face plates 80 through the corrugated core material 803.
1 and 802 are connected, and a pair of face plates 8
A hollow portion 804 is formed between 01 and 802.
Therefore, as compared to a thick aluminum plate, it is lighter and uses a smaller amount of aluminum, thereby reducing costs. On the other hand, a core member 803 is interposed between a pair of face plates 801 and 802. Therefore, it is possible to maintain strength.

Accordingly, in the cargo container 1 of the present embodiment in which the front panel 2 and the pair of side panels 3 are formed by the aluminum corrugated cardboard panel material 8, a thick metal plate material is used as the panel material. Unlike the conventional cargo container used, the weight of the entire container can be reduced and the cost can be reduced, but the durability can be maintained.

Further, in the panel material 8 made of aluminum corrugated cardboard used in this embodiment, as described above, since the core material is corrugated, a hollow portion 804 is formed between the pair of face plates 801 and 802. Even when the outside air temperature is not directly conducted into the cargo container and the outside air temperature is high in summer or the like, it is possible to suppress a rise in the temperature inside the container as compared with the conventional cargo container.

In this embodiment, the panel material 8 made of aluminum corrugated cardboard has a pair of face plates having a thickness of 0.2 to 0.3 mm and a total thickness of the panel material of 9 to 1 mm.
