BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing box comprising an upper box and a lower box, and a packing stopper for the packing box.

[0002]

2. Description of the Related Art A conventional packing box composed of an upper box and a lower box has a spacer and a product inserted into a lower box 21 as shown in FIG.
The upper and lower boxes are fastened with three or two pieces.

[0003]

A conventional packing box composed of an upper box and a lower box uses the PP band 23 for packing. Therefore, the work of passing the P band 23 through the lower box 21 and the stopper The additional work is required, so that the packing is not easy, and since the lower box 21 is transported in an assembled state during transportation, the quantity that can be loaded on one truck is limited. Was a problem.

The present invention makes it possible to eliminate the work of using the PP band and to transport the lower box in a sheet state in a packing box composed of an upper box and a lower box. It is intended to provide a packing stopper capable of connecting the lower box and the upper box.

[0005]

SUMMARY OF THE INVENTION Accordingly, in order to achieve the above-mentioned object, a first aspect of the present invention is to provide a first ring plate having a first opening in a rectangular shape and a second ring plate in a rectangular shape. A second ring plate on which a pair of locking legs for inserting and locking into the first opening is provided around the opening, and a second ring plate is provided around the third opening in a rectangular shape. Alternatively, a third ring plate having a pair of flat plate-shaped legs inserted into the first opening and having an L-shaped cross section hinged to a tip of the flat plate-shaped legs by a bendable thin portion. And inserted into the first opening via the second and third openings, and press the short side of the L-shaped cross section to extend the long side of the L-shaped cross section outside the first opening. And a hinge having a pair of legs provided at a tip thereof with a protruding portion which is bent and locked.

According to a second aspect of the present invention, the first ring plate, the second ring plate, the third ring plate, and the hinge are hinged to each other by thin portions, and are integrally formed of plastic.

According to a third aspect of the present invention, left and right side plates are connected to each other on the left and right sides of the bottom plate via a fold, and the first opening is substantially equal to the first opening through the folds above and below the left and right side plates. A folding plate having four openings is continuously provided, and upper and lower side plates having a fifth opening substantially equal to the first opening at both ends at upper and lower sides of a bottom plate are successively provided. The side plate and the left and right side plates are bent around the bottom plate to stand up, respectively, and the folding plate is bent in the direction of the upper and lower side plates to connect the fourth and fifth openings with the first and second ring plates. A lower box is formed, the lower box is covered with an upper box having a sixth opening substantially at the same position as the connection position of the fourth and fifth openings, and the third ring plate and the hinge are provided. Is inserted into the first opening through the sixth opening to connect the lower box and the upper box.

[0008]

According to the invention, the lower box is assembled with the first ring plate and the second ring plate, and the upper box and the lower box are connected to the third ring plate by hinges. , Second
By integrating the ring plate, the third ring plate and the hinge, the number of parts used for packing can be reduced,
Since the PP band is not used when packing, the work of passing the PP band through the lower box can be eliminated, and the lower box can be transported in the form of sheets, so the number of lower boxes that can be loaded per transport vehicle increases and transport The cost is reduced and the above problem is solved.

The stoppers connected in one vertical line and the second ring plate 2, the first ring plate 1, the third ring plate 3, and the hinge 4 in FIG. The connected stopper and the connecting plate 5 at the lower part of the second ring plate 2 from FIG.
The first ring plate 1 is connected via the
Is connected to the lower part of the third ring plate 3 via a connection plate 5,
A stopper having a hinge 4 connected to the left or right of the third ring plate 3 via a connection plate 5, and a second ring plate 2 provided below the first ring plate 1 via the connection plate 5 as shown in FIG. And a third ring plate 3 is connected to a lower portion of the second ring plate 2 via a connection plate 5, and a hinge 4 is connected to either the left or right of the third ring plate 3 via the connection plate 5. 5 and 8, the second ring plate 2 is connected to the lower portion of the first ring plate 1 via the connection plate 5 from FIGS. 5 and 8, and the left and right sides of the second ring plate 2 are connected via the connection plates 5. 6 and 7, a stopper connecting the third ring plate 3 and the hinge 4 with the stopper.
The first ring plate 1 is connected to the lower part of the ring plate 2 via the connection plate 5, and the third ring plate 3 and the hinge fastener 4 are connected to the left and right of the first ring plate 1 via the connection plate 5. There is a stopper.

When the packing stopper as described above is used in a packing box composed of an upper box and a lower box, the lower box 6 shown in FIG.
When assembling, the stopper hole 12 in which the fourth and fifth openings are overlapped with each other, and the four locations are fastened with the first ring plate and the second ring plate 2, and the lower box 6 is assembled. When the upper box 7 is put on the lower box 6, a sixth opening (stopper hole) 13 is formed.
Then, the third ring plate 3 and the hinge fastener 4 are inserted to connect the upper box and the lower box.

[0012]

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

Since there is no need to use the PP band which has been used at the time of packing, the troublesome work of passing the PP band through the lower box can be omitted, and the four structures of the stopper can be connected to the connecting plate. The number of parts can be reduced because the lower box is assembled on a line, so the lower box can be transported in the form of sheets when transporting the lower box, and when transported in the previously assembled state More transport can be performed at one time than at a time, and the transportation cost can be reduced.
