  As shown in FIG. 28, when the container main body 10A is further stacked on the container main body 10A to which the lid body 10B is attached (that is, the container 10 with a lid), as shown in FIG. The lower surface is received by the upper end connecting wall 61C of the annular bank 61 of the lid 10B, and the fitting protrusion 19 of the upper container body 10A is fitted inside the annular bank 61. The lid rail portion 67 of the long side bank portion 66 of the annular bank portion 61 is formed between the fitting projection 19 of the upper container body 10A and the first and second lower surface side projections 14 and 15 on both sides thereof. Sandwiched between them. As shown in FIG. 28, the first and second engaging protrusions 40 and 45 of the upper container body 10A are engaged with the first and second engaging recesses 64 and 65 of the lid 10B. To do.

  As shown in FIG. 29, when the lid body 10B is stacked on the folded container body 10A, the annular frame portion 62 (see FIG. 23) of the lid body 10B has the corner protrusion 12A in the container body 10A. (See FIG. 4) While fitting inside the group, the first and second engaging protrusions 70 and 75 of the lid 10B are received by the protrusion receiving part 34 of the container main body 10A. Further, when the lids 10B and 10B are stacked, the annular frame part 62 of the upper lid 10B is received inside the annular bank 61 of the lower lid 10B, and the first lid 10B has a first shape. And the second engagement protrusions 70 and 75 are received in the first and second engagement recesses 64 and 65 of the lower lid 10B.

  The description regarding the structure of the container 10 with a lid of this embodiment is above. Next, the effect of this lidded container 10 will be described. As described above, when the container main body 10A in the container 10 with a lid according to the present embodiment stacks the container main bodies 10A, the upper container main body 10A is replaced with the first side wall 30 of the lower container main body 10A, It can be slid along the rail portion 33 on 30 and stacked.

  Here, it is considered that such a container main body 10A is used as a container with a lid on which a lid is attached. However, when the lid is attached, the rail portion 33 of the container main body 10A is covered with the lid. Therefore, when another container with a lid is slid on the upper side, a problem may arise that the upper lid side container with a lid may be shifted to the side, and the work cannot be performed smoothly.

  In contrast, in the lidded container 10 of the present embodiment, since the lid rail portion 67 is formed on the lid body 10B attached to the container main body 10A, the upper stage even when the lid body 10B is attached. The side covered container 10 (container main body 10A) can be smoothly slid. Hereinafter, the effect of the container 10 with a lid | cover with which the cover body 10B was mounted | worn with the container main body 10A, the stacking | stacking of the container 10 with a lid | cover, and the operation | work spreading will be demonstrated.

  As shown in FIGS. 32 and 35, when the lid body 10B is mounted on the container body 10A, the lower surface of the main plate 60 of the lid body 10B comes into contact with the uppermost end surface of the container body 10A, and the annular frame portion of the lid body 10B. 62 is received in the upper surface opening 10K of the container main body 10A, and the lid 10B is positioned with respect to the container main body 10A. Here, since the annular frame 62 for positioning the lid 10B with respect to the container body 10A is configured to be received inside the container body 10A, the annular frame 62 holds the container body 10A from the outside. It is possible to make the lid 10B more compact than the surrounding configuration. At this time, there is a concern that dust or the like enters the container 10 with a lid through the gap between the side walls 20 and 30 of the container body 10A and the lid body 10B, but the rail projection 33T on the first side wall 30 of the container body 10A. Is covered with the cover wall 66G of the lid body 10B, so that dust or the like can be prevented from entering the lidded container 10 or between the ribs of the rail portion 33.

  Further, since the first and second engaging protrusions 70 and 75 of the lid 10B engage with the first and second engaging recesses 24 and 25 of the container body 10A, the second side wall 20 of the container body 10A. Is prevented from falling outward, and the rib extending portion 86 of the lid 10B is disposed outside the first side wall 30 of the container main body 10A, so that the first side wall 30 of the container main body 10A falls outside. This is also prevented.

  Stacking containers 10 and 10 with lids is performed by the same operation as stacking container bodies 10A and 10A. That is, as shown in FIG. 30, the operator lowers the container main body 10A (hereinafter simply referred to as “container main body 10A” in the description of the stacking operation) of the upper-stage lidded container 10 at one end in the longitudinal direction. The lower end portion of the long-side bank 66 in the lid body 10B (hereinafter simply referred to as “lid body 10B” in the description of the stacking operation) is a raised portion. It hits an arbitrary position on the back side from 66U. At this time, the pair of lid rail portions 67 and 67 of the lid body 10B are sandwiched between the fitting projection 19 of the container body 10A and the pair of first lower surface side projections 14 and 14 on both sides thereof. .

  Next, the other end in the longitudinal direction of the inclined container body 10A is pushed toward one end in the longitudinal direction of the lid 10B. Then, the upper container body 10A is guided by the lid rail portion 67 of the lid body 10B and moves toward one end portion in the longitudinal direction of the lid body 10B. When the upper container body 10A is pushed in as it is, when the container main bodies 10A are stacked, the first lower surface side protrusion 14 of the upper container body 10A becomes the first overhanging protrusion 50 of the lower container body 10A. As in the case of riding up (see FIG. 14), the first lower surface side projection 14 of the container body 10A rides on the fourth overpass projection 80 of the lid 10B (see FIG. 31). At this time, since the small protrusion 66T formed on the back side of the fourth overpass protrusion 80 is in contact with the first overpass protrusion 50 of the lower container body 10A, the load received by the fourth overpass protrusion 80 is distributed. Is done.

  As shown in FIG. 33, when the first and second engaging protrusions 40 and 45 of the container body 10A get over the upper end communication wall 61C of the short side bank 63, the first lower surface side protrusion 14 is Passes through the four-passing protrusion 80 In addition, since there is a step between the upper surface of the fourth overpass projection 80 and the upper end connection wall 61C of the annular bank 61 in the lid body 10B as in the upper part of the first side wall 30 of the container body 10A (see FIG. 24). When the first lower surface side protrusion 14 moves on the fourth overpass protrusion 80, the first lower surface side protrusion 14 does not come off from the lid rail portion 67.

  The first and second engaging protrusions 40 and 45 of the container body 10A are in sliding contact with the upper portions of the first and second engaging recesses 64 and 65 of the short side bank portion 63 of the lid 10B. 10A further moves to one end side while descending, and as shown in FIG. 28, the first and second engaging protrusions 40 and 45 engage with the first and second engaging recesses 64 and 65, respectively, As shown in FIG. 34, the fourth overpass projection 80 engages with the concave and convex portions between the first lower surface side projection 14 and the second lower surface side projection 15. In this state, when the other end of the container body 10A is lowered, the first and second engagement protrusions 40 and 45 of the container body 10A are also engaged with the first and second engagements of the lid 10B on the other end side. The concave and convex portions 64 and 65 are engaged with the concave and convex portions, and the container body 10A on the upper side is in a horizontal posture and the containers with lids 10 and 10 are stacked (see FIG. 28). Note that the lid body 10B may be covered after only the container body 10A is stacked by sliding movement, or the container body 10A with the lid body 10B mounted in advance (that is, the container 10 with the lid) is slid and stacked. You may make it do.

  In the stacked state of the containers 10 and 10 with lids, the first and second engagement protrusions 40 and 45 and the first and second engagement recesses 64 and 65, as well as the first and second engagement recesses 64 and 65, The lower surface side protrusion 14 and the fourth overpass protrusion 80 are engaged with each other, and the fitting protrusion 19 is fitted inside the annular frame 62, thereby causing lateral displacement between the upper and lower containers 10 and 10 with lids. It is prevented.

  The stacking of the stacked containers 10 and 10 in the stacked state is performed by the same operation as the stacking of the container main bodies 10A and 10A. In other words, the container 10 with the lid on the upper stage is tilted, and the end of the first lower surface side protrusion 14 on the second lower surface side protrusion 15 side becomes the fourth overpass projection of the lid 10B of the container 10 with the lower cover. It is put on the corner part of the part 80 (refer FIG. 36). Then, as shown in FIG. 37, when the container 10 with the lid on the upper stage is brought close to a horizontal posture and pulled forward, the first and second engagement protrusions 40 and 45 of the container body 10A on the upper stage are The first and second engaging recesses 64 and 65 of the lid 10B of the container 10 with the lid on the lower side are separated (see FIG. 33). Then, the first lower surface side protrusion 14 is guided by the inclined rib 81 of the fourth overpass protrusion 80 and smoothly descends from the fourth overpass protrusion 80, and the upper lid side covered container 10 is pulled and lifted as it is. be able to.

  As described above, according to the lidded container 10 of the present embodiment, the lid 10B includes the fitting projection 19 of the upper container body 10A and the pair of first lower surface side projections 14 and 14 on both sides thereof. Since the lid rail portion 67 that is sandwiched and engaged is provided, the upper container body 10A is guided by the lid rail portion 67 of the lid body 10B, and the slide stack between the lidded containers 10 and 10 is provided. Operation becomes possible.

  Similarly to the first overpass projection 50 provided on the container body 10A, a fourth overpass projection 80 for guiding the first lower surface side projection 14 of the upper container body 10A upward is provided on the lid body 10B. Therefore, when the containers 10 and 10 with lids are stacked together, the containers 10 with lids on the upper side are stacked without lifting each other in the same manner as when stacking the container bodies 10A and 10A. It is possible to efficiently stack the lidded containers 10 and 10 together.

  As shown in FIG. 38, the container 10V with a lid of the present invention may be configured such that the lid body 10B is in contact with the rail portion 33 of the container main body 10A. The clearance generated between the lid rail portion 67 and the fitting protrusion 19 and the first lower surface side protrusions 14 and 14 of the upper container body 10A and the lower body side when the container bodies 10A are stacked. The difference between the rail portion 33 of the container main body 10A and the clearance generated between the fitting protrusion 19 and the first lower surface side protrusions 14 and 14 of the upper container main body 10A increases. For this reason, for example, if the fitting protrusion 19 and the first lower surface side protrusion 14 of the container body 10A are designed so that the clearance easily engages when the container bodies 10A are stacked, the container 10V with a lid When 10V is stacked, sufficient clearance is not obtained, and it is considered that a malfunction occurs when the slide stack operation is performed.

  However, in this embodiment, the lid rail portion 67 of the lid body 10B protrudes upward from the main plate 60 that contacts the upper surface of the rail portion 33 of the container main body 10A, and the width of the rail portion 33 and the lid rail portion 67 Since the difference from the width can be reduced, the above-described problems can be prevented.
