Each cutout portion 103 is provided on the information display surface 80 (that is, the protruding portion 58) at a position adjacent to each door engaging operation member 90 in the width direction D3 of the door 50. Each notch 103 has a part of the operation portion 192 and the finger insertion space portion 194 of each door engagement operation member 90 regardless of the slide operation of each door engagement operation member 90. Therefore, the operation unit 192 and the finger insertion space unit 194 are longer in the width direction D3 of the door 50 than in the above embodiment.

In the container 101 having such a configuration, the sliding operation of each door engaging operation member 90 is made possible by the cutout portion 103 in which the information display surface 80 (that is, the protruding portion 58) is cut out. Therefore, in the width direction D3 of the door 50, the sliding operation of each door engaging operation member 90 can be performed so as to overlap with the information display surface 80. Therefore, the operability of the door engaging operation member 90 is improved.

Further, when each cutout portion 103 is provided near the center of the information display surface 80, the operation portion 192 of the pair of door engaging operation members 90 and the finger insertion space portion 194 come close to each other. Therefore, since the operator can handle the operation portion 192 and the finger insertion space portion 194 of the pair of door engagement operation members 90 with one hand, the operability of the door engagement operation member 90 is improved.

Further, when each notch 103 is covered with a label or the like attached to the information display surface 80, the label or the like can be easily peeled off from the information display surface 80 by using each notch 103. be.

Specifically, each door engaging operation member 90 includes a finger insertion space portion 194 in which a space is formed from the information display surface 80 toward the inside of the container 1. A part of each finger insertion space portion 194 is included in each notch portion 103 regardless of the sliding operation of each door engaging operation member 90. Therefore, when each notch 103 is covered with a label or the like attached to the information display surface 80, each notch 103 is covered from the outside of the label (that is, the outside of each notch 103) via each finger insertion space 194. An operator inserts a finger or the like into the notch 103. As a result, the label or the like can be more easily peeled off from the information display surface 80.

(5-2) Second Modification Example Alternatively, as in the container 201 shown in FIG. 12, a door engaging operation member 290 that is slid in the vertical direction D1 may be provided. An example of such a change will be described below. However, in the following description, the same reference numerals are given to the parts substantially in common with the above-described embodiment, and detailed description thereof will be omitted.

The door engaging operation member 290 penetrates the information display surface 80 (protruding portion 58) along the width direction D3 of the door 50, and is in the vertical direction D1 within the information display surface 80 (protruding portion 58). It is made movable. The door engaging operation member 290 is urged upward by the urging force of the urging member 296. The door engaging operation member 290 is provided with an operation unit 292 at the center of the door 50 in the width direction D3. The operation unit 292 is located outside the door engaging operation member 290 (that is, outside the container 201) in the direction D2 (that is, the direction perpendicular to the paper surface of FIG. 12) orthogonal to the width direction D3 of the door 50. It is a protruding outer peripheral rib. In the operation unit 292, a finger insertion space portion 294 is recessed in the door engagement operation member 290.

On the other hand, an opening 280A is formed in the information display surface 80 (protruding portion 58) at the center of the door 50 in the width direction D3. The opening 280A is provided with an operation portion 292 of the door engagement operation member 290 and a finger insertion space portion 294. In the opening 280A, a part of the first short side side wall portion 30 can be seen above or below the operation portion 292 and the finger insertion space portion 294 of the door engaging operation member 290.

Therefore, the operator hooks his / her finger on the operation portion 292 and the finger insertion space portion 294 of the door engagement operation member 290 through the opening 280A of the information display surface 80 (protruding portion 58), and the door engagement operation member When the 290 is slid downward against the urging force of the urging member 296, the door engaging operation member 90 and the second short side side wall portion 40 are disengaged. On the other hand, when the operator releases the finger from the operation unit 292 and the finger insertion space 294 of the door engagement operation member 290, the door engagement operation member 290 slides upward by the urging force of the urging member 296. Therefore, the door engaging operation member 90 and the second short side side wall portion 40 are engaged with each other, and the engagement is locked.

The operation unit 292 of the door engagement operation member 290 is inward (that is, in the direction perpendicular to the paper surface of FIG. 12) inward from the door engagement operation member 290 in the direction D2 orthogonal to the width direction D3 of the door 50. That is, it may be projected to the back side of the paper surface of FIG. In such a case, since the operation portion 292 and the finger insertion space portion 294 of the door engagement operation member 290 exist in the inner surface side recess 84 on the back surface of the information display surface 80, the second short side side wall portion It is possible to hang the operator's finger from the side of the inner wall surface 42 of the 40. Therefore, it is possible to omit the opening 280A. However, it is necessary to omit a part of the vertical rib portion 86 or the horizontal rib portion 88 of the inner surface side recess 84.

(5-3) Others The information display surface 80 may be further projected as compared with the door engaging operation members 90, 290 and the operation units 92, 192, 292. In such a case, the label or the like attached to the information display surface 80 is in a state of being even easier to see.

The container 1 of the present embodiment is a so-called foldable container, but it may be a container that cannot be folded.

The door 50 is supported by the hinge portion 70, the bearing portion 72, and the like on the second short side side wall portion 40 so as to be openable and closable, but may be supported so as to be openable and closable by sliding or attaching / detaching.
