Description

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

[Prior art]

In the conventional container shown in Japanese Utility Model Application Publication No. 56-72724, after a reinforcing frame with a square cross section is engaged with the upper end of each side plate of the container, which is bent into a box shape, each side plate to which the reinforcing frame is attached is inserted. Corner blocks are attached to the ends of the side plates, and these containers and reinforcing frames are tightened and fixed using bolts and nuts to form a box-shaped container.

[Problem that the invention attempts to solve]

However, since the conventional container described above is formed into a box shape by connecting the ends of each side plate with corner blocks, a reinforcing frame must be specially provided at the upper end of each side plate in order to obtain container strength. Not surprisingly, the number of component parts was increasing. For this reason, there was a problem in that the ease of assembly of the container was poor. Furthermore, in the container shown in the above publication, the container, reinforcing frame, corner blocks, and fixing pins are made of different resins or metals, so when the container is crushed and reused as a molding raw material, each resin is It was necessary to separate each product separately, which increased the number of steps required for reuse. For this reason, the resin in the container could not be effectively reused. Furthermore, the nut that screws the tip of the bolt inserted into the through hole protrudes from the inner surface of the upper end of the reinforcing frame, which may get in the way when storing the product in the container, or may damage the stored product. are doing.

[Purpose of invention]

The purpose of the present invention is to take into account the above-mentioned drawbacks of the conventional technology.
Assembly work is extremely easy with a small number of parts,
It is an object of the present invention to provide a container that prevents the products contained therein from being damaged and allows the container to be effectively reused as a resin raw material.

[Means for solving problems]

For this reason, the present invention has a rectangular frame shape, an inner wall in which a locking recess is formed, and a locking part that hangs down at a position corresponding to the locking recess and has a through hole formed that matches the locking recess. A frame having an approximately H-shaped vertical cross section, and a rectangular resin corrugated board made of the same synthetic resin as the frame and having notches at each corner, forming respective side edges. a through hole that stands upward at a position corresponding to the depth of the box, the upper part of which is inserted between the inner wall and the locking part, and the upper part of the side edge that matches the through hole of the locking part; a box body formed with a shank, a shaft part that is made of the same resin material as the box body and the frame, and has an outer diameter corresponding to the inner diameter of the through hole, and a claw part that engages with the inner surface of the locking part; The container is characterized by comprising a fixing pin having a head that comes into contact with the outer surface of the locking part.

[Effect of invention]

Since the present invention is constructed as described above, the upper part of each side edge of the resin corrugated board that stands upward is placed between the inner wall of the frame and the locking part at a location corresponding to the depth of the box to be formed. After fitting, when the fixing pin is inserted into the matching through-hole and the through-hole, the claw part of the fixing pin engages with the inner surface of the locking part to prevent it from coming off, and the tip of the shaft is inserted inside. It is engaged with a locking recess in the wall. Thereby, each side edge of the box body can be fixed to the frame while avoiding the shaft tips of the fixing pins protruding from the inner surface of the container, that is, the inner surface of the inner wall. When the product is stored in the container, it is possible to prevent the product from being damaged by the fixing pins, and the product does not become an obstacle to the storage operation. Further, after the container is used, since each member of the container is made of the same resin, each member can be crushed and reused as a molding material without disassembling the container.

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

FIG. 1 schematically shows a container according to the present invention, FIG. 2 shows a cross section taken along the line A-A in FIG. 1, FIG. 3 shows a fixing pin, and FIG.
In the figure, a container 1 is composed of a frame 3, a box body 5, and a fixing pin 7, and the frame 3, box body 5, and fixing pin 7 are made of the same synthetic resin, such as polypropylene or ABS resin.

The frame 3 has a rectangular frame shape, and its vertical cross section is formed into a substantially h-shape. A flange portion 9 is integrally formed at the upper end of each frame side of the frame 3 so as to extend outward in a planar manner. A hanging portion 13 serving as an inner wall is integrally molded inside the support step portion 11 of the frame 3. Also, frame 3
A large number of fixed wall portions 15 as locking portions are integrally formed on the outside of the supporting end portion 11 of the support end portion 11 with a required distance from the hanging portion 13 and at a required interval in the lateral direction. A through hole 17 is formed in each fixed wall portion 15 with an inner diameter corresponding to a shaft portion 7a of a fixed pin 7, which will be described later. A hooking recess 19 is formed on the outer surface of the hanging part 13 so as to correspond to the through hole 17 .

As shown in FIG. 4, the box body 5 is made of a substantially rectangular resin corrugated board with notches corresponding to the height of the box shape in which each corner is formed, and the resin corrugated board is defined by the broken lines shown in the figure. Two pairs of side plates 5a, 5b, 5c, 5d and bottom plate 5 facing each other by bending at certain positions
It is formed into a box body 5 consisting of e. A large number of through holes 21 are provided at the upper end of each side plate 5a, 5b, 5c, 5d at a required interval downward from the upper end of the side plate 5a, 5b, 5c, 5d, and at a required distance according to the shaft portion 7a. Formed at the inner diameter.

A resin corrugated board 5 is fixed to the frame 3 via fixing pins 7. The fixing pin 7 has a shaft portion 7a having an outer diameter corresponding to the inner diameter and the fixing wall portion 1.
5 and the fixed wall portion 1.
5 and a head 7c that abuts on the outer surface are integrally molded. After inserting the upper ends of the side plates 5a, 5b, 5c, and 5d into the required space between the hanging portion 13 and the fixing wall portion 15, the fixing pin 7 is inserted into the through hole 17 and the through hole 21 that almost coincide with each other. is inserted, and the shaft end of the shaft portion 7a is latched in the latching recess 19, and the claw portion 7b is engaged with the inner surface of the fixed wall portion 15.

Next, a method for assembling the container 1 will be explained with reference to FIGS. 2 and 4.

In FIGS. 2 and 4, each side plate 5a, 5
A resin corrugated board with through holes 21 formed in the upper ends of b, 5c, and 5d is bent at the broken line position shown in FIG. It is formed into a box body 5.

Then, the upper end portions of each of the side plates 5a, 5b, 5c, and 5d are inserted between the hanging portion 13 and the fixed wall portion 15, and the box body 5 is temporarily fixed to the frame 3. At this time, the through hole 17 of the fixed wall portion 15, the through hole 21 of the box body 5, and the latching recess 19 of the hanging portion 13 are substantially aligned.
