It is configured as follows. By forming in this way, the folding container with a lid is assembled into a box shape, and in a state where the short side wall 3 stands substantially vertically, the virtual outer surface of the short side wall 3 (the upper horizontal rib 3b, the lower horizontal rib 3c and the upper side As shown in FIG. 26 and the like, the short side bank portion 1b of the bottom portion 1 is a virtual surface 3 ′ formed by the tips of the end vertical rib 3d, the upper horizontal rib 3h, the side section vertical rib 3i, and the like. Is formed so as to be located on the inner side by a predetermined distance D5 from the outer vertical plate portion 1b3 constituting the.

  And as above-mentioned, virtual outer surface 3 'of the short side wall 3 is comprised so that only the predetermined distance D5 may be located inside from the outer side perpendicular board part 1b3 which comprises the short side bank part 1b of the bottom part 1. FIG. Thus, when the opening of the folding container body assembled in a box shape is covered with the pair of half-lid bodies 4, the gap between the long side hanging ribs 4d1 of the pair of half-lid bodies 4 is as described above. A gap approximately twice as long as the distance D5 is formed. In this gap, the lower meshing member 4f and the upper meshing member 4e are engaged with each other, in other words, the lower meshing of one half lid 4 is engaged. The upper meshing member 4e of the other half lid 4 is arranged on the member 4f so as to overlap.

  Next, the locking process and unlocking process of the long side wall 2 and the short side wall 3 will be described with reference to FIGS.

  As shown in FIG. 4, from the state in which the lidded folding container is folded, first, the short side wall 3 on which the hinged half-lid body 4 is overlapped is rotated, and FIG. As shown, stand upright.

  Next, when the long side wall 2 folded so as to overlap the bottom portion 1 is rotated in the vertical direction, the belt-like engagement frame 2 f of the long side wall 2 faces the engagement frame 3 e of the short side wall 3. When approaching and further rotating the long side wall 2 in the vertical direction, the tip of the upper fitting convex portion 2g of the long side wall 2 is fitted into the fitting concave portion 3f ′ of the box-shaped fitting portion 3f of the short side wall 3. Will be inserted. When the tip of the upper fitting convex portion 2g of the long side wall 2 is inserted into the fitting concave portion 3f ′ of the box-shaped fitting portion 3f of the short side wall 3, the box-shaped fitting portion 3f The side plate 3f3 is configured to be inserted into a gap 2h formed between the tip of the horizontal plate 2g2 facing the upper fitting convex portion 2g and the side vertical rib 2e. Before and after the process of inserting the upper fitting convex portion 2g into the fitting concave portion 3f ′ of the box-shaped fitting portion 3f, as shown in FIG. 32, the engaging portion 6f of the side wall lock member 6 is obtained. The inclined plate 6f2 formed on the abutting plate abuts on a plate-like engaging portion 3e3 that is suspended from the lower end of the lower surface of the box-shaped protrusion 3e2 of the short side wall 3. Thereafter, when the long side wall 2 is further rotated in the vertical direction, the free end portion of the side wall lock member 6 is placed on the upper surface of the elastic strip supporting projection 2m formed on the long side wall 2. The elastic strip 6c moves downward against the elastic force caused by the elastic deformation of the elastic strip 6c. Due to the downward movement of the side wall lock member 6, the engagement portion 6f of the side wall lock member 6 becomes the engagement frame of the short side wall 3 when the engagement portion 6f passes the lower end of the plate-like locking portion 3e3. The side wall lock member 6 is moved upward by the restoring force of the elastic strip 6c disposed in the side wall lock member 6 while entering the insertion port 3g formed in 3e, and the engaging portion 6f is formed in a plate shape. The engaging recess 3e4 positioned behind the locking portion 3e3 enters the upper fitting convex portion 2g of the long side wall 2 and the fitting concave portion 3f ′ of the box-shaped fitting portion 3f of the short side wall 3 completely. Will be inserted. In this way, the folded container body in the folded state is assembled into a box shape. When the folding container body is assembled in a box shape in this way, the lower fitting convex portion 2i formed on the belt-like engagement frame 2f of the long side wall 2 is engaged with the short side wall 3. It is comprised so that it may be located under the box-shaped fitting part 3f currently formed in the frame 3e.

  As described above, even if an external force is applied to the long side wall 2 from the state in which the long side wall 2 is tilted toward the bottom 1 from the state assembled in the box shape, the side wall lock member 6 attached to the long side wall 2 is engaged. The joining portion 6f abuts on a plate-like locking portion 3e3 that is suspended from the lower end of the box-shaped protrusion 3e2 of the short side wall 3, and accordingly, the rotation of the long side wall 2 in the direction of the bottom 1 is prevented. It will be.

  As shown in FIG. 1, in order to fold the folding container body of the folding container with a lid assembled into a box shape, first put a hand into the box-shaped handle portion 6b of the side wall lock member 6. An operator lowers the side wall lock member 6 against the elastic force of the elastic strip 6c so that the engaging portion 6f of the side wall lock member 6 is a plate-like member formed on the short side wall 3. The engaging recess 6e is discharged from the engaging recess 3e4 located behind the stopper 3e3, and the engaging portion 6f is positioned below the lower end of the plate-like locking portion 3e3. Next, the long side wall 2 is tilted in the direction of the bottom 1 and overlapped with the bottom 1. Next, the folding container body assembled in a box shape can be folded by tilting the short side wall 3 in the direction of the bottom 1 and placing it on the long side wall 2 stacked on the bottom 1.

  Next, with reference to FIGS. 35 to 38, a description will be given of the cover of the half-lid body 4 hinged to the short side wall 3 to the folding container body assembled in a box shape.

  After the folding container body is assembled in a box shape, the half lid body 4 that overlaps the short side wall 3 located on the left side shown in FIG. 2 is replaced with a female hinge member for lid H3 and a male hinge for lid. As shown in FIG. 36, the pair of half-lid bodies 4 are arranged in a mountain shape so that the front ends thereof are close to each other, as shown in FIG. Next, the pair of half lids 4 is placed on one half lid 4 so that the upper meshing member 4e of the other half lid 4 is placed above the lower meshing member 4f of the other half lid 4. The lower meshing member 4f of the lid 4 and the upper meshing member 4e of the other half lid 4 are meshed. In this way, the opening of the folding container body assembled in a box shape is covered with the pair of half-lid bodies 4, and when the pair of half-lid bodies 4 is covered, FIG. As shown, the distal end of the lid locking member 5 on the insertion portion 5 a 2 side is in a position retracted from the distal end of the half lid 4.

  Further, since the pair of half-lid bodies 4 are configured identically, when the opening of the folding container main body assembled in a box shape is covered with the pair of half-lid bodies 4, FIG. As shown, the insertion portion 5a2 of the lid locking member 5 attached to one half lid 4 is inserted into the insertion port 4h4 of the lid lock fitting member 4h formed in the other half lid 4. It is comprised so that it may oppose.

  As described above, when the opening of the folding container main body assembled in a box shape is covered with the pair of half-lid bodies 4, between the long-side hanging ribs 4d1 of the pair of half-lid bodies 4, A gap approximately twice as long as the distance D5 is formed. In this gap, the lower meshing member 4f and the upper meshing member 4e are engaged with each other. Since the upper meshing member 4e of the other half-lid body 4 overlaps with the mating member 4f, it is placed on the pair of half-lid bodies 4 of the folding container with lid assembled in a box shape. Even if an object is placed, the half lid 4 can be prevented from being deformed or damaged.

  In addition, since the upper meshing member 4e of the other half lid 4 is arranged on the lower meshing member 4f of the other half lid 4, the upper half meshing member 4e is disposed between the pair of half lids 4. Thus, no gap is formed, and therefore, it is possible to prevent dust and the like from entering the folding container with a lid assembled in a box shape.

  As described above, the opening of the folding container body assembled in a box shape so that the lower meshing member 4f of one half lid 4 and the upper meshing member 4e of the other half lid 4 are meshed with each other. When covered with the pair of half-lid bodies 4, as shown in FIG. 36, the rod-like locking portion 4f2 of the lower meshing member 4f is in the fitting recess 4e ′ of the upper meshing member 4e. And the front plate 4e2 of the upper meshing member 4e is inserted into a groove 4f ′ formed between the rod-shaped locking portion 4f2 and the long side hanging rib 4d1. By configuring in this way, when the opposing short side walls 3 standing substantially vertically are going to fall in a direction away from each other, the front side plate 4e2 of the upper meshing member 4e is moved to the lower meshing member. It is possible to prevent the short side walls 3 that are hooked on the bar-shaped locking portion 4f2 of 4f from falling in a direction away from each other. In addition, even when the locking state of the long side wall 2 and the short side wall 3 by the side wall locking member 6 is inadvertently released, the short side wall 3 can be prevented from falling inward.

  Further, as described above, the front side plate 4e2 of the upper meshing member 4e is inserted into the groove 4f ′ formed between the rod-like locking portion 4f2 and the long side hanging rib 4d1. Therefore, the movement to the outside or the inside of the short side wall 3 is suppressed and the folding containers with lids assembled in a box shape can be stacked in a stable state.

  Further, when the opening of the folding container body assembled in a box shape is covered with the pair of half-lid bodies 4, as shown in FIGS. The fitting protrusion 2q provided on the upper surface in the vicinity of both end portions of 2b is configured to be fitted to the fitting cup member 4g formed on the half-lid body 4. Thus, since the fitting protrusion 2q protruding from the upper end horizontal rib 2b of the long side wall 2 is fitted to the fitting cup member 4g formed on the half lid body 4, the long side wall 2 and the short side rib 2b are short. Even when the locked state by the side wall lock member 6 with respect to the side wall 3 is inadvertently released, the long side wall 2 can be prevented from falling in the direction of the bottom 1.

  Further, as described above, since the fitting protrusion 2q protruding from the upper end horizontal rib 2b of the long side wall 2 is fitted to the fitting cup member 4g formed on the half lid 4, the box shape In addition to improving the rigidity and strength of the folding container with lid, the folding container with lid assembled in a box shape is restrained from moving to the inside or outside of the long side wall 2 when stacked vertically. Therefore, the folding containers with lids assembled in a box shape can be stacked in a stable state.

  As described above, when the opening of the folding container body assembled in a box shape is covered with the pair of half-lid bodies 4, the hooks 5b of the lid lock member 5 attached to the half-lid bodies 4 are The long side wall 2 is configured to be inserted into a through hole 2u drilled in a central portion of a corner portion formed by the upper end horizontal rib 2b and the plate-like portion 2a.

  As described above, after the opening of the folding container body assembled in a box shape is covered with the pair of half-lid bodies 4, the lid lock member 5 attached to one half-lid body 4 is placed on the other side. The lid lock fitting member formed on the other half lid 4 is moved forward in the direction of the lid lock fitting member 4h formed on the other half lid 4 so that the insertion portion 5a2 of the lid lock member 5 is inserted into the other half lid 4. 4h, the insertion portion 5a2 of the lid lock member 5 is inserted into the insertion port 4h4 of the lid lock fitting member 4h. As shown in FIG. The climbing projection 5d suspended from the lower surface 5a ′ of the main body 5a of the locking member 5 climbs over the bridging locking frame 4a4 located on the front surface of the insertion port 4h4, and the main body 5a of the lid locking member 5 Engagement part of hook 5b suspended from lower surface 5a ' b2 is the lower surface 2b2 of the upper horizontal rib 2b of the long side wall 2, and is configured to be positioned abutting or close to. Therefore, the pair of half-lid bodies 4 covering the opening of the folding container body assembled in a box shape is centered on the hinge connecting portion formed by the lid female hinge member H3 and the lid male hinge member H4. Even if it is going to rotate, the engaging portion 5b2 of the hook 5b suspended from the lower surface 5a ′ of the main body portion 5a of the lid locking member 5 contacts or approaches the lower surface 2b2 of the upper horizontal rib 2b of the long side wall 2. Therefore, it is possible to prevent the half lid body 4 from rotating and the opening of the folding container body from being opened. In this manner, the lid cover member 5 locks the half-lid body 4 that covers the opening portion of the folding container body assembled in a box shape. At the same time, since the insertion portion 5a2 of the lid locking member 5 attached to one half lid 4 is inserted into the lid lock fitting member 4h formed on the other half lid 4, the half lid It can prevent more reliably that the body 4 rotates and the opening part of a folding container main body is opened.

When inserted into the lid lock fitting member 4h formed on the other half lid body 4, the overpass projection 5d formed on the lid lock member 5 is inserted into the insertion port 4h4 of the lid lock fitting member 4h. Since the bridge-like locking frame 4a4 located on the front surface of the lid is positioned over the half-lid body 4, the insertion portion 5a2 of the lid lock member 5 attached to one half-lid body 4 is formed in the other half-lid body 4. Even if it is going to be ejected from the lid lock fitting member 4h, the climbing protrusion 5d formed on the lid lock member 5 comes into contact with the bridge-like locking frame 4a4, so it can be easily attached to one half lid body 4. Inserted portion of the lid locking member 5 5a2 is discharged from the lid lock fitting member 4h formed on the other half lid body 4, and the lid is locked by the lid lock member 5 by the lid lock member 5 and the upper end horizontal rib 2b of the long side wall 2. Can be prevented from being released.

  When the folding container with a lid assembled in the box shape shown in FIG. 1 is folded as shown in FIG. 4, first, the lid is attached to one half lid 4 for the lid. 39. With the finger placed on the ridge 5e of the operation portion 5a3 of the lock member 5, the lid lock member 5 is moved in the direction of the connecting ridge 4j2 of the guide ridge 4j having a U-shaped planar shape. As shown in FIG. 4, the insertion portion 5a2 is discharged from the lid lock fitting member 4h formed on the other half lid body 4. Thereafter, a finger is applied from below the half lid 4 to the lower surface of the tip of one or both half lids 4 located in the notch recess 2b1 formed in the upper end horizontal rib 2b of the long side wall 2. Lifting the tip of one or both half lids 4 releases the meshing between the lower meshing member 4f of one half lid 4 and the upper meshing member 4e of the other half lid 4. Then, the half-lid body 4 is rotated around the hinge connecting portion formed by the female hinge member H3 for lid and the male hinge member H4 for lid, and the half-lid body 4 is overlapped with the short side wall 3 in a substantially vertical state. When the half lid 4 is overlaid on the short side wall 3, the fitting cup member 4 g formed on the half lid 4 is inserted into the upper fitting recess 3 m formed on the short side wall 3. It is configured.

  Next, as described above, the side wall lock member 6 attached to the long side wall 2 is moved downward so that the engagement portion 6f of the side wall lock member 6 is moved from the engagement recess 3e4 formed in the short side wall 3. The long side wall 2 is tilted in the direction of the bottom portion 1 and overlapped with the bottom portion 1. Thereafter, the short side wall 3 is tilted in the direction of the bottom part 1 and is superimposed on the long side wall 2 superimposed on the bottom part 1. At this time, the short side wall 3 is formed on the inner surface 3 e 1 of the engaging frame 3 e of the short side wall 3. The box-shaped protrusion 3e2 and the plate-like locking portion 3e3 are formed on the sides of the long side female hinge member H1 ′ located at the center of the long side bank 1a of the bottom 1 A box-shaped fitting portion 3f formed in the inner surface 3e1 of the engagement frame 3e of the short side wall 3 while being inserted into the recess 1h is an outer open recess formed in the long side bank portion 1a of the bottom portion 1. It is configured to be inserted into the part C2.

  Further, as described above, when the short side wall 3 on which the half lids 4 are stacked is tilted substantially horizontally, as shown in FIG. 41, the box shape formed on the short side wall 3 is formed. Engagement ribs 3f2 'suspended from the bottom surface of the bottom plate 3f2 of the shape fitting portion 3f are vertical ribs of the side wall portion f2 constituting the lifting prevention member F formed on the long side bank portion 1a of the bottom portion 1 From this state, the short side wall 3 on which the half-cover 4 is overlapped is forcibly forced to come into contact with the short side wall engaging projection 1j projecting on the side surface on the 1f side. By approaching the bottom portion 1, the engaging protrusion 3 f 2 ′ formed on the short side wall 3 moves downward beyond the short side wall engaging projection 1 j formed on the long side bank portion 1 a of the bottom portion 1. It is comprised so that it may move to 1 and it may be located under the engaging protrusion 1j for short side walls. Thus, when the short side wall 3 is tilted, the engaging ridge 3f2 ′ formed on the short side wall 3 is engaged with the short side wall engaging portion 1a formed on the long side bank portion 1a. Since it is located below the protrusion 1j, even if the short side wall 3 tries to move upward, the engaging protrusion 3f2 ′ formed on the short side wall 3 is formed on the long side bank portion 1a of the bottom portion 1. Accordingly, the short side wall 3 is prevented from moving upward, and the short side wall 3 is transported or transported during the transport of the folded folding container with the lid. However, rattling can be prevented.

  Furthermore, as described above, when the short side wall 3 on which the half-lid body 4 is stacked is tilted substantially horizontally, the upper end portion of the side plate 4h1 constituting the lid lock fitting member 4h of the half-lid body 4 The bottom engaging protrusion 4h1 'formed on the bottom portion 1 is formed on the inner side portion 1d2 constituting the both-side open recess 1d where the locking intermediate rib 1d3 of the bottom portion 1 is not formed. From this state, the front end portion of the half lid body 4 is forcibly brought closer to the bottom portion 1 to thereby engage the bottom lid portion 4 formed on the half lid body 4.
