Furthermore, as shown in FIG. 10, the corner member 4 can be prevented from coming off upward by being engaged so as to cover the protruding portion 4 f.
Thus, the corner | angular part of the said simple assembly-type storage box 1 is comprised and assembled.

As described above, according to the simplified assembling type storage box 1 according to the first embodiment of the present invention, since the reinforcing members 3 are engaged with the four corners, the load resistance can be improved. .
Further, since the L-shaped recess 4d of the corner member 4 is fitted to the reinforcing member 3, the reinforcing member 3 can be prevented from coming off. Furthermore, the first slit 2e formed continuously with the end 2d of the short side plate 2b or the long side plate 2c is provided at one end and the convex piece 2g is provided with the second slit 2f at the other end. Since the concave portion 4g of the member 4 is fitted and attached, it is possible to prevent the side plate 2b or 2c from finely moving in the longitudinal direction.
Further, the corner member 4 installed above the reinforcing member 3 is provided with the protruding portion 4f having the same shape as the insertion recess 5e in the edge member 5, thereby engaging with the edge member 5. The corner member attached to the housing 2 prior to the edge member 5 since the engagement portion 5d is engaged with the claw portion 2i which is a slip-off preventing member while making the engagement easy and good. It is possible to prevent 4 from coming out upward.
Further, since the shoulder 4e protruding from both end portions of the holding piece 4c contacts and fits with the holding piece 5f in the edge member 5, the edge member 5 is prevented from tilting outward. can do.
Further, the edge member 5 is provided with the upper end surface 5c which is flush with the upper end surface 4b of the corner member 4, so that the load of another simple assembly type storage box placed above can be loaded around the circumference. It can be received on the surface. Therefore, since the said load can be disperse | distributed, durability of the said simple assembly-type storage box 1 can be improved.
Furthermore, since the holding piece 4c and the holding piece 5f that form the same plane orthogonal to the upper end surface 4b and the upper end surface 5c are provided, another simple assembly type storage box placed above is displaced. Can be prevented.
Further, since the upper end surfaces of the holding piece 4c and the holding piece 5f are the same plane, when another simple assembly type storage box is placed on the upper side, the outer side of the short side plate 2b or the long side plate 2c. Dust etc. do not enter from the inside.
Moreover, in the simple assembling-type storage box 1 of the present invention, since a process such as welding or screwing is not required, it can be assembled immediately and easily. This eliminates the need for an assembly machine.
Further, in the edge member 5, only the longitudinal dimension differs depending on the short side plate 2 b or the long side plate 2 c, but in the reinforcing member 3 and the corner member 4, members common to four corners are provided. Since it can be used, the assembly process is not complicated because the left and right directions of the members are confused.

  Moreover, in the said Example 1, when the bulk in the said housing | casing 2 is low and the reinforcement of a corner | angular part is not required, it can also be set as the specification which does not use the said reinforcement member 3. FIG.

  Furthermore, when the plate thickness is made thinner than the housing 2 shown in the first embodiment (for example, about 5 mm thick), as shown in FIG. 12, the housing 2A is assembled in a box shape. In addition, it is possible to secure the strength of the corners by extending both ends of the long side plate 2c having the rib R4 in the same direction as the vertical direction to provide the superposed piece 2k. Like the short side plate 2b and the long side plate 2c in the first embodiment, the overlapping piece 2k has an end 2d, a first slit 2e, a second slit 2f, a convex piece 2g, and a claw 2i. It has the same shape as the said part in the said short side board 2b in the said Example 1, and the said long side board 2c. The overlapping piece 2k preferably overlaps approximately half in the longitudinal direction of the short side plate 2b, but has at least an end 2d, a first slit 2e, a second slit 2f, a convex piece 2g, and a claw 2i. It is a good idea if there is.

  Here, in the first embodiment, it has a predetermined plate thickness (for example, about 9 mm thick), and as shown in FIG. 2, when assembled into a box shape, it is orthogonal to the vertical direction. When the claw portion 2i is provided on the short side plate 2b having the rib R4, the claw portion 2i is provided along the rib R4, but has a predetermined plate thickness. Even when the edge member 5 was pulled upward, the edge member 5 was not bent from the pressing portion 2j. Therefore, since the strength of the claw portion 2i is not impaired, it is possible to prevent the engagement portion 5d of the edge member 5 from coming off upward.

  However, in the case 2A (for example, about 5 mm thick) having a thickness smaller than that of the case 2 shown in the first embodiment, when assembled in a box shape, the vertical direction is orthogonal to the above. When the claw portion 2i is provided on the short side plate 2b having the rib R4, the claw portion 2i is similarly provided along the rib R4. However, the strength of the plastic cardboard is small, and the edge member 5 is provided. When the claw part 2i is bent upward from the pressing part 2j after being attached, the edge member 5 is pulled out, and the engagement part 5d in the edge member 5 is pulled out upward. It may not be possible to prevent.

Therefore, as another specification of the first embodiment when reducing the plate thickness, as shown in FIG. 12, the housing 2A has the rib R4 in the same direction as the vertical direction when assembled in a box shape. A similar claw portion 2i is provided on the overlapping piece 2k extending from both ends of the long side plate 2c.
Thereby, even when the strength of the plastic corrugated cardboard is small, the rib R4 in the claw portion 2i has an effect of reinforcing against the bending from the pressing portion 2j. As a result, the strength is increased, and the edge member 5 Even after being attached, when it is pulled upward, it does not bend from the pressing portion 2j. Therefore, it is possible to prevent the engagement member 5d from coming off upward in the edge member 5.

FIG. 12 and FIG. 13 show the bending of the housing 2A in another specification of the first embodiment when the plate thickness is reduced.
Specifically, the bottom plate 2a is bent into a valley fold as shown in FIG. 13 so that the bottom plate 2a becomes the bottom through the fold line P of the short side plate 2b and the long side plate 2c in the housing 2A shown in FIG. Then, the claw portion 2i can be positioned on the inner surface by bending the overlapping piece 2k into the valley fold through the fold line P to the inside of the short side plate 2b, and the edge member 5 The engaging portion 5d can be locked.
In the assembly without the reinforcing member 3, the L-shaped recess 4d in the square member 4 is replaced with the end 2d of the short side plate 2b, the end 2d of the long side plate 2c, and the end of the overlapping piece 2k. Although it differs in that it is fitted to the portion 2d, the rest is the same as in the first embodiment.

  A second embodiment of the simple assembly type storage box of the present invention will be described with reference to FIGS. The simple assembly type storage box according to the second embodiment is the same as the configuration according to the first embodiment, but only the removal preventing member for the edge member 5 is different. Only the portion relating to the removal preventing member will be described below.

  As shown in FIG. 14, in the short side plate 2b and the long side plate 2c on the inner surface of the housing 2B assembled in a box shape, an engagement groove 2l is formed in the first slit 2e along the longitudinal direction by thermal processing or the like. Is provided at a lower position. In addition, due to processing efficiency, the engagement groove 21 can extend beyond the first slit 2e to the end 2d. The position of the engagement groove 21 corresponds to the position where the engagement portion 5d of the edge member 5 is attached.

  In the housing 2B according to the second embodiment configured as described above, the reinforcing member 3 and the corner member 4 are attached by the same method as in the first embodiment, as shown in FIG. The edge member 5 is attached in the same manner, but as shown in FIG. 16, the engagement portion 5d of the edge member 5 is engaged with the engagement groove 2l of the short side plate 2b. This is different from the first embodiment.

  A second embodiment of the simple assembly type storage box of the present invention will be described with reference to FIGS. The simple assembly type storage box in the third embodiment is similar to the configuration in the first embodiment and the second embodiment, but has another drop prevention member. Only the portion relating to the removal preventing member will be described below.

  As shown in FIG. 17, the short side plate 2b and the long side plate 2c in the case 2C assembled in a box shape have the center piece 2h extending upward and have a folded portion 2m. At the time of pressing, a fold line Q is provided at the boundary between the center piece 2h and the folded part 2m, and the folded part 2m is folded inward toward the inside of the simple assembly type storage box with the fold line Q folded. The end side 2n of the folded portion 2m corresponds to the position where the engaging portion 5d of the edge member 5 is attached.

In the casing 2C in the third embodiment configured as described above, the reinforcing member 3 and the corner member 4 are attached by the same method as in the first and second embodiments as shown in FIG. It is done. Also, the edge member 5 is attached in the same manner, but as shown in FIG. 19, the end side 2n of the folded portion 2m is engaged with the engaging portion 5d of the edge member 5, This is different from the first embodiment and the second embodiment.
In the slip-off preventing member according to the third embodiment, since the folded portion 2m is bent, it is effective when creating a thin and easy-to-assemble storage box having a relatively small repulsive force at the time of bending. .

In addition, as shown in FIG. 20, in a case 2D different from the case 2C, the boundary between the center piece 2h and the folded portion 2m has a certain distance from the end in the longitudinal direction of the center piece 2h. A plurality of cutting portions 2o are provided.
The housing 2D configured as described above is assembled in the same manner as in the first embodiment as shown in FIGS. Also, in the folded portion 2m, unlike the case where the fold line Q is provided, the cut portion 2o is exposed, so the folded portion 2m is not only in the inner direction of the simple assembly type storage box, but in the outer direction. You will be able to fold. Further, when bending in the outer direction, the engagement portion 5d of the edge member 5 can be similarly locked by providing the end portion on the outer piece 5a side.

  A fourth embodiment of the simple assembly type storage box of the present invention will be described with reference to FIGS. The simple assembly type storage box according to the fourth embodiment is similar to the configuration according to the first to third embodiments, but has another drop prevention member. Only the portion relating to the removal preventing member will be described below.

  As shown in FIG. 23, a mounting hole 2p for installing the handle portion 6 is provided above a substantially central portion of the short side plate 2b in the housing 2E assembled in a box shape. The mounting hole 2p can be provided only in the long side plate 2c, or can be provided in both the short side plate 2b and the long side plate 2c.

As shown in FIG. 24, the casing 2E in the fourth embodiment configured as described above is attached with the reinforcing member 3 and the corner member 4 by the same method as in the first to third embodiments. It is done. Further, the handle portion 6 having a plurality of protrusions 6a is installed in the mounting hole 2p so that the protrusions 6a are positioned upward. The protrusion 6a corresponds to a position where the engagement portion 5d of the edge member 5 is attached.
Also, the edge member 5 is attached in the same manner. However, as shown in FIG. 25, the protrusion 6a in the handle portion 6 is engaged with the engagement portion 5d in the edge member 5. This is different from the first to third embodiments.
In the removal preventing member in the fourth embodiment, since it is engaged with the protrusion 6a, it is not necessary to have the folded portion 2m as shown in the third embodiment, and the most common having the handle portion 6 is provided. It is effective in a simple assembling type storage box used for the above.
Moreover, in the said handle part 6, regardless of the said specification, the handle etc. which have the lid | cover for dust prevention can also be used.

  A fifth embodiment of the simple assembly type storage box of the present invention will be described with reference to FIGS. The simple assembly type storage box in the fifth embodiment is the same as the structure in the first to fourth embodiments, but as shown in FIG. As shown in FIG. 27, the reinforcing member 3 and the corner member 4 are attached by the same method as in the first to fourth embodiments. Also, the edge member 5 is attached in the same manner. However, as shown in FIG. 28, the edge member 5 is connected to the outer piece 5a by the elastic force of the inner piece 5b and the engaging portion 5d. Thus, since the short side plate 2b is held, it can be prevented from coming out upward.

A sixth embodiment of the simple assembly type storage box of the present invention will be described with reference to FIGS. The simple assembly type storage box in the sixth embodiment is the same as the configuration in the first to fifth embodiments, but the casing 2G has the short side plate 2b and the end 2d of the long side plate 2c. Is different in that it has a claw portion 2i. The said claw part 2i has the press part 2j in the same direction as the perpendicular direction assembled in a box shape. Further, the pressing portion 2j is located on the edge side of the short side plate 2b and the long side plate 2c, is provided at a substantially central portion in the vertical direction, and is processed in the same manner as in the first embodiment.
Further, as shown in FIG. 30, in the reinforcing member 3A having a configuration substantially similar to that of the reinforcing member 3, an engaging portion 3e is provided at the end of the inner holding piece 3a toward the gap 3d. .

In the housing 2G according to the sixth embodiment configured as described above, a reinforcing member 3A is attached as shown in FIG. At this time, the engaging portion 3e in the reinforcing member 3A is locked to the claw portion 2i in the short side plate 2b and the long side plate 2c. Accordingly, the short side plate 2b and the long side plate 2b and the long side plate 2c and the long side plate 2c and the reinforcing member 3A in the first to fifth embodiments can be fixed to each other more securely than only by fitting. It is possible to prevent the side plate 2c from finely moving in the longitudinal direction.
The structure in the sixth embodiment is the same as that in the first to fifth embodiments in the corners of the casing 2, the casing 2B, the casing 2C, the casing 2D, the casing 2E, and the casing 2F. It goes without saying that it can be applied to all the structures where the slab is installed.

  Moreover, in the said Example 2 thru | or Example 5, it was the structure which installs the said reinforcement member 3 in the corner | angular part of the said housing | casing 2B, the housing | casing 2C, the housing | casing 2D, the housing | casing 2E, and the housing | casing 2F. In addition, like the simple assembly type storage box of another specification in the first embodiment, the end of the short side plate 2b or the long side plate 2c is folded and overlapped with the adjacent side plate to reinforce the corners, It can also be set as the simple assembly-type storage box which does not use the reinforcement member 3. FIG.

  Furthermore, it is needless to say that the removal preventing members in the first to fifth embodiments can be arbitrarily combined in one simple assembly type storage box.

  A seventh embodiment of the simple assembly type storage box of the present invention will be described with reference to FIGS. The simple assembly type storage box in the seventh embodiment is the same as the configuration in the first to sixth embodiments, except that the bottom plate 2a, the short side plate 2b, and the long side plate 2c are not integrally formed. In the seventh embodiment, the bottom plate 2a and the long side plate 2c are integrally formed, and the short side plate 2b is welded to the bottom plate 2a later, so that both are integrated.

  As shown in FIG. 32, the short side plate 2b in the housing 2H has substantially the same width from the crease P to the lower end as in the first to sixth embodiments, and extends a predetermined dimension. As shown in a), the lower end surface of the extended portion is preliminarily halved by thermocompression bonding, and a step portion is provided to form a welding allowance 2q. On the other hand, as shown in FIG. 32, the bottom plate 2 a at both ends of the bottom plate 2 a on the side not having the long side plate 2 c is preliminarily halved at the upper end surface by thermocompression as shown in FIG. 34 (a). A step portion is provided to form a similar welding allowance 2q. Alternatively, the welding margin 2q may be formed by making the upper end surface of the short side plate 2b substantially half and the lower end surface of the bottom plate 2a substantially half.

  Later, the short side plate 2b and the bottom plate 2a are thermally welded by polymerizing the welding allowance 2q of both as shown in FIGS. 33 and 34 (b). Thereby, the short side plate 2b and the bottom plate 2a can be integrated, and the upper end surface of the bottom plate 2a can be made smooth.

  Further, as shown in FIG. 35, the bottom plate 2a in the housing 2I has a substantially similar width in the longitudinal direction from the fold line P similar to that of the first to sixth embodiments, and extends a predetermined dimension. As shown in 36 (a) and (b), both ends of the short side plate 2b and the bottom plate 2a can be butted and heat-welded. In such a case, it is a matter of course that the dimension substantially the same as the extending dimension of the bottom plate 2a is cut from the lower end of the short side plate 2b.

  Further, using the bottom plate 2a in the housing 2I and the short side plate 2b that does not cut the above-described extension dimension, as shown in FIG. It can also be polymerized and thermally welded to the extended portion. Moreover, it can superpose | polymerize from the inside of a simple assembly-type storage box, and can also be heat-welded.

  In addition, as shown in FIG. 37 (b), using the bottom plate 2a that does not have the above-described extension dimension in the housing 2I and the short side plate 2b that has the extension dimension from the lower end, assembling can be easily assembled. The extended portion of the short side plate 2b can be polymerized and heat-welded from the outside of the box. Moreover, it can superpose | polymerize from the inside of a simple assembly-type storage box, and can also be heat-welded. The welding which superposes the extended part as shown in FIG. 37 is effective when the plate thickness is thinner than the butt welding.

In the housing 2H and the housing 2I according to the seventh embodiment, a simple assembly type storage box having such a size that the bottom plate 2a, the short side plate 2b, and the long side plate 2c cannot be integrally formed, for example, a length of 800 mm, a width of 600 mm, and a height. It is effective when molding 600 mm. Further, since the short side plate 2b is later welded to the bottom plate 2a, in the assembled state, the rib R4 can be arranged in the vertical direction similarly to the long side plate 2c, so that it is particularly effective in the structure in which the claw portion 2i is provided. is there. Moreover, since the direction where the rib R4 is arrange | positioned in the short side board 2b and the long side board 2c corresponds, the design property can also be improved. Furthermore, it goes without saying that the arrangement direction of the ribs R4 on the short side plate 2b can be made perpendicular to the direction in which the ribs R4 on the long side plate 2c are arranged.
Further, it is needless to say that the structures in the first to sixth embodiments can be adopted.

Further, in the first to seventh embodiments, the plastic cardboard pieces R having the ribs R4 in a certain direction as shown in FIG. 38 are used, but they are arranged in a certain direction as shown in FIG. 39 and FIG. A plastic cardboard S having a substantially cylindrical rib S4 can also be used. The plastic corrugated board S has a flat plate in which an inner side surface S1 and an outer side surface S2 are parallel, and the ribs S4 are provided at predetermined intervals in the gap between the flat plates. Further, the gap between the ribs S4 constitutes a through hole S3.
Further, as shown in FIG. 39 (b), the rib S4 is formed so as to form a substantially cylindrical upper portion on the inner surface S1 side and to be connected to the adjacent rib S4 on the outer surface S2 side. Of course, a substantially cylindrical upper portion can be provided on the outer surface S2 side.

By using the plastic corrugated cardboard S for the casing in the above-described embodiment, it is not necessary to pay attention to the direction of the rib R4 generated when the plastic corrugated cardboard piece R is assembled into a box shape. Can be eliminated.
In particular, the claw portions 2i having the same strength as the adjacent side plates can be formed without considering the direction of the rib S4 as shown in the first embodiment, which is effective.
