Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a container used for transporting or transporting products.

[Prior Art] Conventionally, in the container shown in Japanese Utility Model Application Publication No. 56-72724, a reinforcing frame having a U-shaped cross section is fitted to the upper end of each side plate of a box-shaped container, and then an L is attached to the corner of each side plate. A corner block in the shape of a letter was attached to the reinforcing frame. These corner blocks, side plates, and reinforcing frame are fixed with fixing pins to form the container into a box shape.

[Problems to be solved by the invention] However, the above-mentioned conventional methods, for example,
As shown in Publication No. 72724, it consists of a reinforcing frame with a U-shaped cross section that is fixed to the top of each side plate of a box-shaped container with screws, etc., and corner blocks that are engaged with each corner of the box-shaped container. A returnable box is listed.

[Problems that the invention aims to solve] However, in the case of the above-mentioned returnable boxes, the corner blocks are simply inserted and fixed into each corner of the box-shaped container, and there is no possibility of contact with other returnable boxes. 2 and 3 of the same publication, there is a risk that the engaged state of the corner block may be opened due to the reinforcing frame being fixed to the upper part of the side plate with screws. As shown in the figure, a nut for screwing the screw appears inside the box container containing the product. For this reason, there is a risk that the product may be damaged by the nuts when or when the product is accommodated in the box container.

This invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to remove dust from the corners when a single sheet of resin corrugated board is bent to form a box. It is possible to prevent foreign substances such as the like from entering the box, and it is also possible to prevent the product from being damaged by preventing the members that fix the frame and the box from being exposed on the inner surface when assembled. The purpose is to provide a container.

[Structure of the invention] For this reason, the present invention provides a container in which a box body made of a resin corrugated board and bent into a box shape is fixed to the hanging part of a frame formed in a rectangular frame shape. The longitudinal section of the section is approximately inverted U-shaped, and a large number of through holes are formed at predetermined intervals in the longitudinal direction on the outer side wall.
A recess is formed in the inner side wall corresponding to the through hole, and the box body has a notch formed on the opposite side edge of each corner at a position corresponding to the depth of the box body and having a width corresponding to the depth. , compressing and deforming both sides of the notch to approximately 1/2 the thickness of the resin corrugated board,
A rectangular resin corrugated board with a large number of through holes formed on each side edge corresponding to the through holes of the frame is erected with each side edge at a position corresponding to the depth of the box, and the compressed The deformed parts are overlapped to form a box shape, and a fixing pin having a locking protrusion on the outside of the shaft is inserted into the through hole of the hanging part of the frame and the upright part of the box body inserted into the hanging part. When inserted into the hole, the locking protrusion of the fixing pin engages with the inner surface of the outer side wall of the frame, and the tip of the shaft of the fixing pin can be inserted into the recess provided in the inner side wall of the hanging part. It is characterized by the following.

[Operation of the invention] After raising each side edge of the resin corrugated board at a position corresponding to the depth of the box to be formed,
When folded around the notches at each corner, approximately 1/2
The parts compressed and deformed to a thickness of 2 are overlapped.
This allows each corner of the box to overlap, so
This prevents foreign matter such as dust from entering from the corner, and since the parts compressed and deformed to approximately 1/2 the thickness are overlapped, the overlapped part is similar to the thickness of other resin corrugated boards. Almost matched. Also,
After the box body formed by folding as described above is attached to the hanging part of the frame so that the through holes in the side edges and the through holes provided in the hanging part of the frame match, these transparent parts are attached. When the fixing pin is inserted into the hole, the shaft end of the fixing pin is locked in the recess, and the locking protrusion is engaged with the inside of the outer side plate of the upright portion. This restricts the fixing pin from coming out of the through hole, and also restricts the shaft end from protruding inside the frame.

[Example] Hereinafter, the present invention will be explained according to examples.

In FIG. 1 schematically showing a container according to the present invention, FIG. 2 showing a cross section taken along the line A-A in FIG.
is composed of a frame 3, a resin corrugated board 5, and a fixing pin 7, and these frame 3, resin corrugated board 5, and fixing pin 7 are made of the same synthetic resin, such as polypropylene resin or ABS resin. The frame 3 has a rectangular frame shape and is integrally molded to have an H-shaped vertical cross section. That is, on the outside of the support stepped portion 9 of the frame 3, there is a flange portion 11 that extends upwardly and then outwardly in a planar shape.
are integrally molded. Further, a hanging part 13 is integrally molded inside the support step part 9, and a large number of recesses 15 are formed in the hanging part 13 to catch the shaft end of a fixing pin 7, which will be described later. A large number of fixed walls 17 are formed on the outside of the support step 9 at required intervals in the lateral direction, and are integrally molded to correspond to the recesses 15 . A through hole 19 is formed in each fixed wall portion 17 in correspondence with the recess 15 .

The resin corrugated board 5 has a substantially rectangular shape, and a notch 21 is formed at each corner with a width corresponding to the height of the box shape. The overlapping parts 23a and 23b (indicated by diagonal lines in FIG. 3) at each corner of the resin corrugated board 5 facing each other through the notch 21 have a thickness that is approximately 1/1/2 of the thickness of the resin corrugated board 5.
It is compressed and deformed so that it becomes 2 or less. The resin corrugated board 5 thus formed has two pairs of side plates 5a, 5 facing each other as shown by broken lines in FIG.
It is bent into a box shape consisting of b, 5c, 5d and a bottom plate 5e. At this time, each overlapping portion 23a, 23
b are superimposed on each other. The resin corrugated board 5
A large number of through holes 25 are provided at the upper ends of the side plates 5a, 5b, 5c, 5d and the overlapping portions 23a, 23b.
are formed corresponding to the recess 15 and the through hole 19. The through hole 25 has an inner diameter corresponding to the shaft portion of the fixing pin 7, and is integrally punched out using a press device (not shown).

A fixing pin 7 is inserted into the through hole 19 and the through hole 25. The fixing pin 7 has a shaft portion 7a having an outer diameter corresponding to the through hole 25, a locking protrusion 7b that locks on the inner surface of the fixed wall portion 17, and a head portion 7c that contacts the outer surface of the fixed wall portion 17. It consists of When the fixing pin 7 is inserted into the through hole 19 and the through hole 25,
The end of the shaft portion 7a is hooked into the recess 15.

Next, a method of assembling the container 1 constructed as described above will be explained with reference to FIGS. 2 to 4.

In FIG. 3 and FIG. 4 showing the overlapping state of the overlapping parts 23a and 23b when the resin corrugated board 5 is bent, the resin corrugated board 5 with the notches 21 formed at each corner is shown in FIG. It is bent into a box shape having two pairs of side plates 5a, 5b, 5c, 5d and a bottom plate 5e facing each other at the positions shown by the broken lines. At this time, each overlapping portion 2 facing each other via the notch 21
3a and 23b are overlapped as shown in FIG. Since the overlapping parts 23a and 23b are compressed and deformed in advance so that the thickness thereof becomes approximately 1/2 that of the resin corrugated board 5, the thickness of the overlapping parts 23a and 23b is the same as that of each side plate 5a, 5b, 5c, and 5d. Almost equal to the plate thickness.

In FIG. 2, the upper end of each side plate 5a, 5b, 5c, 5d formed as described above is connected to a hanging portion 13.
and the fixed wall portion 17. At this time, the through holes 25 formed in each side plate 5a, 5b, 5c, 5d are connected to the recess 15 of the hanging part 13 and the fixed wall part 17.
The box-shaped resin corrugated board 5 is temporarily fixed to the frame 3 almost in alignment with the through hole 19 . Next, with respect to the container 1 and the resin corrugated board 5 in the above state, the fixing pin 7 is inserted from the outside of the fixing wall 17 into the through hole 19 and the through hole 25, and inserts the head 7c and the fixing wall 17 into the through hole 19 and the through hole 25.
When inserted until the outer surface abuts, the shaft portion 7a
The shaft end portion of the fixing pin 7 is hooked in the recess 15 and the locking protrusion 7b is locked on the inner surface of the fixing wall portion 17, so that the fixing pin 7 is prevented from coming out from the through hole 19 and the through hole 25. As a result, the frame 3 and the resin corrugated board 5 are integrated with the fixing pin 7, and the box-shaped container 1 is formed.

In this way, in this embodiment, the overlapping parts 23a and 23b facing each other through the notches 21 formed at each corner of the resin corrugated board 5 are arranged such that the thickness of each side plate 5 is
The resin corrugated board 5 is compressed and deformed to approximately 1/2 the thickness of the boards a, 5b, 5c, and 5d.
When folded into a box shape, the mutual thickness of the overlapping parts 23a and 23b is determined by the thickness of the side plates 5a, 5b,
It is possible to make the plate thickness approximately equal to that of plates 5c and 5d. Therefore, each corner of the assembled container 1 can be made substantially flush with each of the side plates 5a, 5b, 5c, and 5d, making it possible to smoothly accommodate products.

[Effects of the Invention] As described above, the present invention can provide a container that can maintain its strength without narrowing the storage space of the container.
