Article container

Abstract

An object is to provide an article storage case which is adapted to be joined to adjacent cases, which is inexpensibly obtainable, and which is easy to recycle. For achieving this object, in an article storage case (1) in the form of a rectangular prism having an opening (2) in the upper region, the outer surface of each of the opening edges of side walls (1a, 1a, 1a, 1a) is provided with a flange (3) extending outward, and the flanges (3) of opposed side walls (1a, 1a) are provided with joining elements comprising a dovetail (4a) and a dovetail groove (4b)of a dovetail joining means (4).

Description

technical field [0001] The present invention relates to an article storage box, and in detail, relates to an article storage box that can be arranged and connected to each other. Background technique [0002] In factories and the like, article storage boxes molded from plastic are used for storing and transporting components. [0003] Such article storage boxes should be provided with a connecting mechanism for connecting the storage boxes to each other so that when the storage boxes are placed on a shelf and then piled up and transported by a forklift, the goods will not collapse. [0004] For example, Japanese Patent Application Laid-Open No. 7-52950 discloses a storage box (plastic container) in which a permanent magnet as a connecting mechanism is installed on the side of the box, and the magnetic force of the magnet connects adjacent storage boxes to each other. connected to each other. [0005] In addition, Japanese Patent Laying-Open No. 9-169339 discloses an articl...

Problems solved by technology

[0008] Furthermore, if the storage box placed outside the house is exposed to wind and rain, water will remain in the storage box, and the operation of draining the water from the storage box will be performed during use, especially if there are articles stored in the storage box. The operation of draining the water in the storage box will be an extremely cumbersome operation, and the operability is not good

[0009] Also, when stacking empty storage boxes for storage, place the bottom peripheral edge of the upper storage box on the upper edge of the opening of the lower storage box in the same way as when storing items in the storage boxes. It will cause volume expansion and take up a lot of storage space

[0010] Furthermore, in a general storage box, since the lower surface of the bottom is formed in a grounded shape as a whole, when the weight of the stored items changes over time and the central part of the bottom is bent downward, the grounded state will deteriorate. Sometimes wobbles when placed on a flat surface and cannot be fixed in place
