Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a corner holder which is effective for assembling a box, in which a flap at the end of a side plate is superimposed on the other side plate at the corner of the box made of cardboard or the like.

Generally, when assembling a box, the corner flaps are fixed by stitching, gluing, etc., but the box cannot be disassembled, which is inconvenient during transportation.

For this reason, the inventors of the present invention have developed a corner holder 1 as shown in FIG. This corner holder 1 consists of a band-shaped flexible piece 2 and an insert body 3 integrally provided at both ends of the flexible piece 2. Each of the inserts 3 has a base plate 4 having a substantially U-shaped outer shape, and an L-shaped flange piece 5 is provided along the outside on one side of the base plate 4, and is continuous to both sides and the lower side of the base plate 4, and A fitting groove 6 with an open outer side is formed. The flexible piece 2 has a plurality of ribs 7 on its upper edge, and is coupled so that the upper edge of the flexible piece 2 and the upper surface of the substrate 4 coincide with each other, and as shown in FIG. A fitting groove 11.12 is formed in the part where the flap 9° 10 is overlapped with the side plate of the other male 2, and the insert body 3 of the corner holder 1 is inserted into these two fitting grooves 11.12, The fitting groove 6 is fitted to the edges of the fitting grooves 11 and 12, and the box is assembled as shown in FIG. Since the groove 6 and the board 4 are not prevented from being pulled out,
If an external impact or pull is applied to the flexible portion 2 and the substrate 4, there is a risk that the flaps 9.10 at the corners of the box 8 may come off from the fitting grooves 11.12 cut out in the flaps 9.10. Furthermore, the plurality of ribs 7 provided on the upper edge of the flexible part 2 are for supporting the load of the stacked upper boxes, and since there is no measure to prevent them from shifting, vibrations and shocks may occur during transportation. There was a problem with the box moving around.

The present invention solves the drawbacks of the box corner holder, which is the premise of the present invention, and examples thereof are shown in Figs. 3 to 3 below.
This will be explained based on FIG.

FIG. 1 shows a corner holder 13 of a box according to an embodiment of the present invention, and this corner holder 13 has anti-slip ribs 1 on the top surface.
4, and insert bodies 16 and 16' integrally provided at both ends of the connecting piece 16.

The can lid insertion body 16.16' has a base plate 17.17' whose outer shape is substantially U-shaped perpendicular to the longitudinal axis of the connecting piece 16, and an L-shaped base plate 17.17' along one side of the base plate 17.17'. flange pieces 18 and 18' are provided, and fitting grooves 19 and 19' are formed by the clamp pieces 18 and 18', and the said board 1
7 and 17', and have fitting grooves 19 and 19' that are open on the outside, and the connecting piece 16 matches the upper surface of the substrate 17 and 17', and the connecting piece 1
The ribs 14 provided on the upper surface of the substrates 17, 17 are slightly
' is joined at a position higher than the top surface.

Fitting grooves 19, 19' of the insert bodies 16, 16'
A pull-out prevention rib 20, 20' is formed inside. Each of these constituent members is integrally formed of a flexible synthetic resin material such as polypropylene.

FIG. 2 shows a box 21 used for assembling the box corner holder 13 of the present invention, the corner portion of which is attached to one side plate 22.
The flaps 24 of the other side plate 23 adjacent to the side plate 23 are overlapped, and the flaps 26 of the side plate 22 are also overlapped, and the side plate 22 and the flap 26, and the side plate 23 and the flap 24 have a common 61-inch insertion groove. 26.27 is formed.

Insert the inserts 16° 16' of the corner holder 13 into the insertion grooves 26 and 27 of the box 21 as shown in FIG.
2. Fit the edges of the insertion grooves of the flap 24, side plates 23, and flaps 26. In this state, the side plate 22
and flap 24 and side plate 23. The flap 26 is connected to the substrate 1
7.17' and the clamp pieces 18 and 18' are clamped and assembled. In addition, when disassembling it, it can be pulled out using the corner holder 13.

FIG. 6 shows a state in which a plurality of boxes 28, 28' assembled with the corner holder 13 of the present invention are stacked,
The bottom part 29 of the upper box 28 is brought into contact with the upper surface of the lip formed on the connecting piece 16 of the corner holder 13 attached to the fitting groove of the lower box 26' and the substrates 17, 17', and is moved by the weight of the upper box 26'. The bottom part 29 can be slightly bitten by the ribs formed on the connecting piece 16 of the corner holder 13 attached to the lower box 28', thereby preventing displacement and making it stable.
− It is now possible to accumulate things.

The corner holder of the present invention is used as described above, and the box can be assembled easily and reliably by inserting the two inserts into the insertion grooves in the corners of the box, and the two inserts are integrated with the connecting piece. In addition to preventing the top box from shifting when stacking boxes, it also prevents the top box from shifting.
The above-mentioned extra weekly holidays are difficult to remove and stabilize the assembly of the box, which has a great practical effect.
