Therefore, even if the substantially vertical door member D, which is substantially flush with the short side wall 3, tries to rotate outward about the hinge member H, the lock portion 5 e formed at the tip of the rod 5 d of the lock member 5. However, it comes into contact with the vertical portion 4a2 of the pair of locking claws 4a constituting the locking member 4 formed on the short side wall 3, the rotation is prevented, and the door member D is not opened.

  When releasing the locked state of the lock portion 5e of the lock member 5 formed on the door member D by the locking member 4 formed on the short side wall 3 as described above, as shown in FIG. A person moves the operation member 6 downward (in the direction of the upper horizontal rib d6 of the door member D) by hand. Then, the inclined rib portion 6b1 formed at the lower corner portion of the peripheral rib 6b of the operation member 6 moves below the inclined guide plate 5g1 of the guide block 5g formed on the lock member 5, and the lock member 5 The elastic member 5 is moved horizontally in the direction of the vertical frame portion 3 b of the short side wall 3 against the elastic force of the elastic strip 5 f of the lock member 5. Due to the movement of the short side wall 3 of the lock member 5 to the vertical frame portion 3b, the lock portion 5e formed at the tip of the rod 5d of the lock member 5 is formed on the outer step portion 3b1 of the vertical frame portion 3b of the short side wall 3. Accordingly, the vertical door member D that is substantially flush with the short side wall 3 can be removed from the back of the vertical portion 4a2 of the pair of locking claws 4a that constitute the locking member 4. At the center, the door member D can be turned outward and the door member D is turned so as to overlap the lower frame 3c of the short side wall 3 so that the opening 3a of the short side wall 3 can be opened.

  As described above, the lock member 5 provided on the door member D is simply moved by moving the operation member 6 provided on the door member D downward (in the direction of the upper horizontal rib d6 of the door member D). Can be moved horizontally in the direction of the vertical frame portion 3b of the short side wall 3 against the elastic force of the elastic strip 5f of the lock member 5 to release the locked state between the short side wall 3 and the door member D. Therefore, the workability of the unlocking operation of the locked state between the short side wall 3 and the door member D is improved.

  After the operation of releasing the locked state between the short side wall 3 and the door member D as described above, when the operator releases his hand from the operation member 6, a pair of lock members is generated by the elastic force of the elastic strip 5 f of the lock member 5. 5, the operation member 6 moves upward (the upper end horizontal flange d5 of the door member D), and the upper surface of the operation member 6 is the upper end horizontal flange of the door member D. It is in contact with d5 or located near the upper end horizontal flange d5.

  When the opening 3 a of the short side wall 3 is closed by the door member D, the door member D superimposed on the lower frame 3 c of the short side wall 3 is rotated upward about the hinge member H. However, when the door member D approaches the opening 3a of the short side wall 3 or before that, as described above, the operation member 6 is moved in the direction of the upper horizontal rib d6 of the door member D, The lock member 5 is horizontally moved in the direction of the vertical frame portion 3b of the short side wall 3 against the elastic force of the elastic strip 5f of the lock member 5, and a lock portion formed at the tip of the rod 5d of the lock member 5 5e is removed from the back of the vertical portion 4a2 of the pair of locking claws 4a constituting the locking member 4 formed on the outer step portion 3b1 of the vertical frame portion 3b of the short side wall 3, and then shorted by the door member D. While closing the opening 3a of the side wall 3, the door member D and the short side wall 3 are substantially flush. After that, when the operator releases his / her hand from the operation member 6, as described above, the pair of lock members 5 move horizontally in a direction approaching each other by the elastic force of the elastic strip 5f of the lock member 5. Then, the lock portion 5e formed at the distal end portion of the rod 5d of the lock member 5 is behind the vertical portion 4a2 constituting the locking member 4 formed on the outer step portion 3b1 of the vertical frame portion 3b of the short side wall 3. Positioned, the door member D is locked to the short side wall 3.

The fitting projection d14 projecting from the inner surface of the overhanging frame d8 formed at the tip of the side end vertical flange d7 of the door member D is configured to fit.

  As described above, in the state in which the opening 3a of the short side wall 3 is closed by the door member D, the fitting hole 3d formed in the outer step portion 3b1 formed in the vertical frame portion 3b of the short side wall 3 is inserted into the fitting hole 3d. The door member D with respect to the short side wall 3 is configured such that the fitting protrusion d14 protruding from the inner surface of the overhanging frame d8 formed at the tip of the side end vertical flange d7 of the door member D is fitted. Can be prevented, and even when a downward load is applied to the door member D, the load is borne by the fitting protrusion d14 fitted in the fitting hole 3d, and the door member D is connected to the hinge member H. The load can be reduced, and therefore damage to the hinge member H can be prevented.

  In the embodiment described above, an example is shown in which the opening 3a is formed in both opposing short side walls 3 and the door member D is disposed. However, the opening 3a is provided only in one short side wall 3. It is also possible to form the door member D. Further, instead of disposing the door member D on the short side wall 3, an opening can be formed on the long side wall 2, and the door member D can be disposed on the opening.

  The folding containers configured as described above are assembled in a box shape, and are arranged in multiple stages in the vertical direction at almost the same interval as the height of the folding container assembled in a box shape in a state where various articles are accommodated. The folding container assembled in a box shape is placed on the shelf, the short side wall 3 on which the door member D is disposed, and the operator is on the work side (passage side). Place them side by side so that they are positioned. In this way, the folding container assembled in a box shape is placed side by side so that the short side wall 3 on which the door member D is disposed is positioned on the work side (passage side). Since more folding containers can be arranged on one shelf, it is therefore preferable to arrange the door member D on the short side wall 3 side.

  Note that the card holders C1 and C2 can be attached to the inner wall surface d2 of the door member D by using an adhesive, by welding, or by the card holders C1 and C2 and the door member D. The inner wall d2 can be attached by projecting a locking projection on one side and forming a recess or hole into which the locking projection can be fitted on the other. Further, the card inserts C1 and C2 can be integrally formed with the door member D by injection molding or the like.

  Since the present invention has the above-described configuration, the following effects can be achieved.

  The door member is provided with one operation member that can be moved in the vertical direction and a pair of lock members that can be moved horizontally by the vertical movement of the operation member. Thus, the locked state of the door member and the side wall by the locking member can be released, and therefore the workability of the unlocking operation of the locked state of the side wall and the door member is improved.

  An opening is formed in at least one side wall, and a door member is disposed in the opening so as to be freely opened and closed, and a card slot is disposed on the inner wall surface of the door member, so that the door member rotates downward. Even if the card disposed on the bottom or the like is hidden by the door member, the article stored in the folding container can be easily recognized and identified without removing the article from the folding container.
