Description

  The present invention relates to a storage container that is suitable for storing and storing solid industrial waste, for example, and can easily check contents at any time.

  Specified hazardous industrial waste such as waste cloth soaked in a small amount of polychlorinated biphenyl (PCB) is now harmless when it is sorted by equipment and stored in a simple package such as a plastic bag. It is stored until processing. During storage, the simple packaging located near the bottom of the drum can be easily damaged when receiving the weight of the contents above it or when removing the contents in the drum for periodic inspection. There was a problem.

  Several proposals have been made for containers for storing such industrial waste. For example, Patent Document 1 proposes an internal storage container that can be stored in an external container such as a drum can for storing radioactive waste. This internal storage container is a regular shaped container that divides the internal space of the external container into a plurality of parts, is easy to handle by hand, has the required strength, and there is no leakage of the contents to the outside. It has an advantage that the efficiency of housing in the external container can be increased. However, this internal storage container is not suitable for storage of solid waste other than radioactive waste and is difficult to be used for general purposes, and once stored, it is not necessary to periodically check the contents. Not only is it difficult to use in the storage work of specific hazardous industrial waste that needs to be periodically checked, but there is also a problem that it is difficult to take out if the contents are heavy. Therefore, it has been desired to solve such a problem.

It can be accommodated by being lifted and inserted from above the outer container 25. After accommodating the inner containers 10, 15, 20 in a stacked state in the outer container 25, the long screw 41 is connected to the screw parts 14, 19, 24 in the openings penetrating the inner containers 10, 15, 20. It may be in a screwed state or removed, and the upper end of the outer container may be covered with a lid 252 and fixed, and if necessary, moved to a predetermined storage location and stored (see FIG. 4).

  Next, an example method for taking out the inner container from the outer container will be described. First, when the lid 252 of the outer container 25 is opened and the uppermost inner container 10 is taken out, as shown in FIG. 4, it is confirmed whether the long screw 41 is housed or removed. When the long screw 41 is removed, the long screw 41 or, if necessary, the long screw 41 for extension (one or two or more joined members of the joining screws 42a to 42c) is attached to the long screw 41. Prepare a joined one, attach a handle 43 to one end thereof, rotate the long screw 41 by inserting a long screw 41 into the opening from the through hole 12b in the lid 12 of the uppermost inner container 10, and open the opening. The screw parts 14, 19, and 24 are respectively screwed. Further, by rotating the handle 43 of the inner container lifting / lowering means 40, the inner container 10 gradually rises, and when the bottom plate 11a of the inner container 10 reaches a position higher than the upper end of the outer container 25, the handle 43 The inner container 10 can be taken out by removing (when the extension long screw 42 is joined, this is also removed together with the handle 43 if necessary). Further, by repeating the same operation, the inner and lower inner containers 15 and 20 can be taken out.
