Embodiments of the present invention will be described below with reference to the drawings. Note that the present invention is not limited only to the following embodiments. 1 to 4, the container body 1 has a canopy 2 which forms a ceiling of the container in a closed state. The canopy 2 has a structure that can be opened almost completely and can be opened almost completely, as shown by a dashed line in the drawing. The canopy 2 is pivotally supported by a shaft extending on the side surface in the longitudinal direction of the container body 1, and pivots upward about this shaft to open. A rear surface of the container body 1 has a pair of upper doors 3 which can be opened and closed in a double-opening manner at an upper part thereof, and a lower door 4 which can be opened and closed downwardly by using a hinge 6 attached to the bottom of the container body as a rotation axis. Consists of The upper door 3 is configured such that the left and right upper doors 3 open left and right, respectively, around a hinge 13 attached to a post (post 12) at the rear of the container body 1 as a rotation axis. The lower door 4 has a lock mechanism 5 that can be locked. The upper door 3 is also provided with lock mechanisms 7 and 8. The top canopy 2 is about 2
The container can be rotated by 60 ° and opened until it is substantially parallel to the side panel of the container body 1. Opening and closing of the canopy 2 is performed by an opening and closing mechanism 9 provided on the upper part of the container body 1. This opening / closing mechanism can be operated manually or electrically. In this embodiment, although not shown in detail, a manual system using hydraulic pressure is adopted. Further, a lock mechanism (not shown) can be provided to prevent careless opening. This lock mechanism can be incorporated in the opening / closing mechanism 9 described above, or can be a separate mechanism.

The lower door 4 at the lower rear of the container body 1
When the lock mechanism 5 is released, the hinge 6 opens downward with the hinge 6 as a rotation axis. As a result, the contents stacked in bulk can be discharged while the upper door 3 is closed. When the contents are to be taken out at once, the upper door 3 is also opened as shown in FIG. Known lock mechanisms 7 and 8 for the upper door can be used. Further, the lock mechanism 5 of the lower door 4 is used to prevent an abnormal opening operation of the lower door 4.
It can be of the hook or screw type. Also,
For example, a watertight packing such as a synthetic resin is preferably attached to a portion of the lower door 4 that contacts the container main body or a corresponding position on the container main body side to prevent water wetting.
As a result, water leakage and environmental pollution can be prevented even during transportation of water-containing waste. Such a watertight packing includes the upper door 3, the container body 1 and the lower door 4.
Can also be provided between. In addition, the rotation axis of the lower door 4 is located at a position lower than the inner floor surface of the container body 1, and in a state where the lower door 4 is opened, the entire lower door 4 is located at a position lower than the floor surface. desirable. This is so that the lower door 4 does not prevent the loading and unloading of cargo.

Further, in the container according to the embodiment, when the waste is loaded and transported, and after the waste is discharged, the inside of the dirty container is cleaned, so that the general cargo can be loaded and transported. The rear part of the container body 1 opens to the floor inside the container, and since there are no protrusions on this floor, in addition to loose stones, bagged cement, building materials, industrial products, etc. loaded on pallets can be used. It can be easily loaded.

The canopy 2 is opened by opening it.
Enables efficient loading of waste and cargo from above.
Note that a hook 10 is provided in front of the container body 1. This can be lifted with a vehicle-mounted crane or the like, lifted on a truck, and fixed. Further, a small wheel 11 having a setback arrangement is provided at the rear of the container so that the container can be easily moved when the front of the container body 1 is lifted. The loading and unloading of the container onto and from the freight wagon can be performed from either side by using a forklift.

The container of this embodiment is designed to be suitable for both transportation by truck or ship and transportation by freight car. Further, by providing the posts 12 at the four corners of the container body 1, the same container or a container
It has a structure that can be stacked in more than two stages. The upper door 3 can be lifted up by providing a double-sided one-sided door that opens sideways and a hinge on the upper part of the upper door 3 and the rear beam of the container body 1 in addition to the double door depending on the intended use. It can also be a single door.

[0010]

As is clear from the above description, according to the present invention, an upper double door is provided on the rear surface of the container body, and a lower door which is opened downward with a hinge as a rotation axis is provided below the upper door. In addition, since the lower door or both the lower door and the upper door are sealed by watertight packing, it is possible to prevent moisture from the load from leaking out of the container. As a result, the transport container of the present invention can transport various wastes, including water-containing wastes, and can also load and transport general cargo after cleaning the inside. In addition, since the rear door is divided up and down, only the relatively narrow lower door is opened to slowly take out granular waste, or only the upper door is opened and the surroundings are inadvertently exposed to the moisture of hydrous waste. Waste can be taken out without contaminating the wastewater.
