Description

[Detailed description of the invention] The present invention is a method of packaging a cube or rectangular parallelepiped article, such as a speaker box, by covering a part of the corner of the speaker box, etc., to protect the speaker box from shocks that occur during transportation and handling. The present invention relates to a corner pad that protects a part of the corner of etc.

Hitherto, various structures have been known for this corner pad, and the simplest one is shown in FIG. 8, as disclosed in Japanese Utility Model Publication No. 50-33415.

To explain the example shown in Fig. 8, four ruled lines are placed in a cross shape on a roughly square cardboard, and the corner portions of the packaged object are portions 1' and 2' that contact both sides, and the portions that contact the top or bottom surface. 3' and 3', and make cuts along the ruled lines between the parts 3' and 3' that come into contact with the top or bottom surface of the packaged object from the intersection of the ruled lines, and make each ruled line inward. a portion 3' that is bent and comes into contact with the upper or lower surface;
3' are stacked and bonded to form a three-sided frame A', and reinforcing plates 11' are fixed to the portions 3' and 3' that contact the top or bottom surface of the packaged object that has been bonded and bonded together, Place a piece of cardboard over the corner of the packaged item and cover the sides of the packaged item.
Since the upper or lower surfaces are only protected by two overlapping sheets of cardboard and a reinforcing plate, they do not have a sufficient shock-absorbing effect.

In addition, when packing items into a packaging box, it is difficult to put them into the packaging box with all the corner pads attached. The packaged items must be dropped so that the corners engage with the corner pads, but the box may tilt and the corner pads shown in Figure 8 above may be misaligned. This makes the work extremely difficult.

The object of the present invention is to eliminate the above-mentioned drawbacks, to provide a sufficient cushioning effect, and to easily and reliably fix the packaging box in a predetermined position.

The basic structure of the present invention to achieve the above object is that the trihedron is composed of three mutually perpendicular plate-shaped hollow pads integrally molded by blow molding of synthetic resin, and the upper or lower surface of the packaged object is The pad that comes into contact with the pad is provided with a hook piece that protrudes from its outer surface.

Hereinafter, embodiments of the present invention will be described based on the drawings.

A is a three-sided frame body, which is made of synthetic resin blow molding and has two side protection pads 1 and 2 that abut along the side surface of a part of the corner of the object to be packaged B, and a part of the corner part of the object to be packaged B that comes into contact with the side surface along the top or bottom surface. One top or bottom protection pad 3 that comes into contact with the
are integrally formed.

Each of the pads 1, 2, and 3 is formed into a sealed hollow plate shape of a substantially right-angled triangle, and is provided at right angles to each other with their right-angled vertices facing each other, so that the three-sided frame A is configured in the shape of a triangular pyramid. There is.

The upper or lower surface protection pad 3 is approximately twice as thick as the side surface protection pads 1 and 2, and a recess 4 that reaches close to the inner surface is provided in the center of the outer surface for reinforcement. There is.

In addition, the end surface of the free end of the upper or lower surface protection pad 3 is inclined at the same angle as the oblique side of the side surface protection pads 1 and 2, and the packaging box C is continuously and flush with this inclined surface 5. A water towel in which a hook piece 7 for hooking onto an inner flap 6 or the like is formed to protrude outward.

The end of the hook piece 7 is bent toward the back side from the middle part to form a hooking part 8, and the hooking part 8 can be folded up so that its base 9 is flush with the base of the hook piece 7. can.

The hook piece 7 has the hook part 8 bent in advance as described above, and may be extended when necessary, or may be extended at first and then bent later.

Further, the hook piece 7 is formed into a roughly T-shape as shown in FIG. This is also possible.

Further, the hook piece 7 does not need to be provided continuously on the sloped surface 5 of the free end of the upper or lower surface protection pad 3, and may be provided at an appropriate position on the outer surface side of the upper or lower surface protection pad 3.

There is no need for the free end of the pad 3 to have an inclined surface.

The length of the hook piece 7 from its base, that is, its base to the base 9 of the hanging part 8 is approximately the same as the thickness of the inner flap 6 of the packaging box C, or is formed to be slightly longer than that. ing.

Therefore, if a punching hole 10 is provided at a predetermined position in the inner flap 6, etc. of the packaging box C, the three-sided frame A can be attached to the inner flap 6, etc. by hooking the hook piece 7 into the punching hole 10. Can be installed and fixed.

To hang the hook piece 7 in the punched hole 10, the hook piece 7 is folded up and stretched, and then inserted through the punched hole 10.
After that, just fold it.

Since the present invention has the above configuration, it has the following advantages.

(1) It is composed of three mutually perpendicular plate-shaped hollow pads that are integrally molded by blow molding synthetic resin, so the cushioning and reinforcement provided by the synthetic resin plates and the air cushion work together, It has excellent buffering and protective effects.

(2) Since a hook is provided on the pad that comes into contact with the top or bottom surface of the packaged item, and the hook protrudes from the outside of the pad, a hole for hooking the hook is provided at a predetermined position on the inner flap of the packaging box, insole plate, etc. By drilling this hole, you can hook the corner pad into the hole and fix the corner pad in a predetermined position in the packaging box. The corner pad does not move or shift its position and can be reliably applied to the corner of the object to be packaged, making it easy to perform packaging work.

In addition, the inner flap of the packaging box and the holes in the insole board can be punched and formed at the same time as the packaging and the original board of the insole board is cut, so positioning can be performed reliably and easily.
