[Problems to be solved by the invention]
In the conventional folding container described above, when the pair of half-covers 5 'are fitted into the opening of the main body C of the folding container, that is, the opening of the frame-shaped upper frame 1, the half-covers The short-side fitting rib portion 5d1 of the fitting rib 5d formed on the inner surface 5c1 of the 5 'plate portion 5c is disposed close to the flat vertical inner surface 1b1 of the short-side frame 1b of the upper frame 1. Since the upper frame 1 is deformed, the short side fitting rib portion 5d1 of the fitting rib 5d abuts on the flat vertical inner surface 1b1 of the short side frame 1b of the upper frame 1, There is a problem that the fitting of the half lid 5 'to the upper frame 1 becomes tight, and the work of fitting the half lid 5' to the upper frame 1 and the work of opening the lid are deteriorated. 1, the half lid 5 ′ is fitted to the upper frame 1. There is a problem that will not come.
[0008]
Further, even in a folding container not provided with a lid, when the upper frame 1 is deformed, it is positioned above when folding containers folded in a box shape or folded are stacked. There has been a problem that the fitting portion of the bottom 2 of the folding container is difficult to fit into the upper frame 1 of the folding container located below.
[0009]
An object of the present invention is to solve the problems of the above-described conventional folding container.
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is hinged to an upper frame, a bottom, a raised side wall, a divided side wall composed of an upper divided side wall and a lower divided side wall, and a long side frame facing the upper frame. In the folding container having a lid formed of a pair of half lids, an opening formed on the inner surface of the plate portion of the half lid by a long side frame facing the upper frame and a short side frame facing each other A fitting rib is formed to be fitted to the portion, and when the fitting rib is fitted to the opening of the upper frame, a short side fitting rib portion constituting the fitting rib is provided. The upper frame is arranged so as to be close to the vertical inner surface of the short side frame of the upper frame, and in the central region of the vertical inner surface of the short side frame of the upper frame, Concave facing the inner surface of the recess substantially parallel to the inner surface Is constituted by a side surface, and, by forming a recess having a lateral width of about 3/4 from 1/3 of the inner width of the short side frame of the upper frame, fitted to the upper frame of said half-lid It is configured to facilitate the combination.
[0011]
【Example】
Examples of the present invention will be described below. However, the present invention is not limited to these examples as long as the gist of the present invention is not exceeded. In addition, the folding container of the present invention has substantially the same configuration except that the configuration of the upper frame is different from the upper frame of the conventional folding container described above. While used, detailed description thereof is omitted.
[0012]
Also in this embodiment, the main body C of the folding container is similar to the main body C of the conventional folding container described above, the upper frame 1, the bottom 2, and the flip-up side wall 3 whose upper end is hinged to the upper frame 1. And a pair of half-lid bodies 5 ′ constituting a lid 5 covered by the main body C of the folding container. Also, the straight long side portion 5a is hingedly connected to the opposed long side frame 1a of the upper frame 1 via a hinge member H1, and the half lid 5 ′ of the conventional folding container described above. Similarly to the inner surface 5c1 of the substantially horizontally long rectangular plate portion 5c of the half lid 5 ', at least a pair of short side fitting rib portions parallel to the opposing short side portion 5e of the half lid 5' 5d1 and half lid as needed Linear fitting rib 5d having parallel long sides fitting rib portion 5d12 the long side 5b of the 5 'is formed.
[0013]
In this embodiment, the concave inner surface 6b is recessed outwardly in the central region of the flat vertical inner surface 1b1 of the short side frame 1b of the upper frame 1 constituting the main body C of the conventional folding container described above. Is formed. The recess 6 is formed by a recess inner surface 6a substantially parallel to the vertical inner surface 1b1, and opposite recess side surfaces 6b connecting both side ends of the recess inner surface 6a and ends of the vertical inner surface 1b1 on the recess inner surface 6a side. ing.
[0014]
As described above, the concave portion 6 is formed by denting the vertical inner surface 1b1 outward in the central region of the flat vertical inner surface 1b1 of the short side frame 1b of the upper frame 1, so that the upper frame 1 is slightly deformed. Even so, the short side fitting rib portion 5d1 of the fitting rib 5d formed on the half lid 5 'does not come into contact with the flat vertical inner surface 1b1 of the short side frame 1b of the upper frame 1, Accordingly, it is possible to prevent the fitting of the half lid 5 ′ to the upper frame 1 from being tight and the workability of fitting the half lid 5 ′ to the upper frame 1 and the opening of the lid from being deteriorated. In addition, it is possible to solve the problem that the upper cover 1 cannot be fitted into the upper cover 1 due to the deformation of the upper frame 1.
[0015]
The lateral width W1 of the recess 6 formed in the central region of the flat vertical inner surface 1b1 of the short side frame 1b of the upper frame 1 is about 1/3 to about 3/4 of the inner width W2 of the opposing short side frame 1b. Preferably it is formed. If the lateral width W1 of the recess 6 is narrower than about 1/3 of the inner width W2 of the short side frame 1b, the deformation of the upper frame 1 cannot be sufficiently absorbed, and the lateral width W1 of the recess 6 is less than the short side. If it is wider than about 3/4 of the inner width W2 of the frame 1b, the opening of the main body C of the folding container, that is, the half lid 5 'fitted to the opening of the frame-shaped upper frame 1 is overly shaky. This is not preferable.
[0016]
In the embodiment described above, an example in which the lid 5 is constituted by a pair of half-lid bodies 5 ′ is shown, but the lid 5 can be formed as a single lid. In this case, one long side portion of the lid 5 is hinge-connected to one long side frame 1a of the upper frame 1 by the hinge member H1 as described above.
[0017]
Further, as described above, the concave portion 6 is formed by denting the vertical inner surface 1b1 outwardly in the central region of the flat vertical inner surface 1b1 of the short side frame 1b of the upper frame 1, so that the upper frame 1 Even if it is slightly deformed, when folding containers that are assembled or folded into a box shape are stacked, the fitting part of the bottom part 2 of the folding container located above is connected to the folding container located below. It can be easily fitted to the upper frame 1 and, therefore, the workability of the stacking work of the folding containers is improved. In addition, when stacking the folding containers, the above-described short-circuiting is performed so that the fitting part of the bottom part 2 of the folding container located above can be easily fitted to the upper frame 1 of the folding container located below. Instead of or in addition to the concave portion 6 formed in the central region of the flat vertical inner surface 1b1 of the side frame 1b, the vertical region is perpendicular to the central region of the flat vertical inner surface of the long side frame 1a of the upper frame 1 A concave portion can be formed by denting the inner surface outward.
[0018]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0019]
Since the concave part was formed on the flat vertical inner surface of the upper frame by recessing the vertical inner surface to the outside, the fitting of the lid to the upper frame was tightened, and the lid was fitted to the upper frame and the lid was opened. It is possible to prevent the workability of the work from being deteriorated, and it is possible to solve the problem that the lid cannot be fitted to the upper frame due to the deformation of the upper frame.
[0020]
Since the concave portion is formed on the flat vertical inner surface of the upper frame by recessing the vertical inner surface to the outside, the bottom portion of the folding container positioned above is stacked when stacking the folding containers not provided with the lid. Can be easily fitted to the upper frame of the folding container located underneath, thus improving the workability of the folding container stacking operation.
