Description

[Detailed description of the invention] This invention is designed to protect the corner edges of items that have a certain weight and are vulnerable to external shocks during transportation, such as enamel bathtubs, furniture, electrical appliances, and kitchen equipment. This invention relates to a side corner ridge protector for packaging heavy goods.

Conventionally, cushioning materials such as styrofoam were used alone, or combinations of styrofoam and corrugated paper, styrofoam and wood, or corrugated paper and wood were used to protect the edges of articles. .

However, although Styrofoam is highly effective in absorbing impact energy, it is weak in strength, and if it is used alone, if a strong force is applied due to an impact such as a fall, the Styrofoam itself may deform or break beyond its allowable strength. death,
This has the drawback of damaging the corner edges of the article.

Therefore, in order to overcome the strength disadvantages of using styrofoam alone, a structure that can withstand use has been created by combining a cushioning material such as styrofoam with wood or corrugated paper.

However, in this case, the structure is complicated, the number of parts is large, the manufacturing process requires a lot of effort, and the manufacturing cost is high.

In addition, it is difficult to dispose of Styrofoam, which is the most commonly used material, after use, and it is currently contributing to pollution problems, and the use of Styrofoam is socially undesirable. be.

Therefore, this project was started with research to eliminate the above-mentioned conventional drawbacks, and the material was found to be corrugated paper. If used as is, it would be inferior in both cushioning and strength. The present invention has been completed to provide a side corner ridge protector for heavy packaging goods that has various advantages.

The purpose of the present invention is to provide an inner ridge protector that is inexpensive and easy to assemble. The upper end plate 2d of the side plate 2C1 and the inner side plate 2e are arranged in series to form a bent overlapping side plate 2, and the upper plate is attached to the rear edge of the overlapping fixed upper plates 3, 3 arranged on both left and right sides of the upper plate 1. 1 bent heavy metal side plate 2 outer plate 2a, lower end plate 2b, middle side plate 2C1 upper end plate 2
d, outer plates 4a, 4a, and lower end plate 4 connected to inner plate 2e;

And the inner side plates 4e and 4e are arranged in a row to form a folded and overlapping side plate 4.
. b, 4 b
Convex overlapping side plate bending holes 6, 6 are provided in the continuous portions of the middle side plates 4c, 4c and the upper end plates 4d, 4d, and the overlapping fixed upper plates 3, 3 are overlapped on the upper plate 1. The horizontal width of the fixed upper plates 3, 3 is set so as to match the vertical width of the upper plate 1, and the vertical width of the outer plates 4a, 4a connected to the rear edges of the overlapping fixed upper plates 3, 3 is set to match the vertical width of the upper plate 1. A bent overlapping side plate 2 whose width is shortened by the thickness of the upper plate 1, and a bent overlapping side plate 2 formed at the rear edge of the upper plate 1, and a bent overlapping side plate 4 formed at the rear edge of the overlapping fixed upper plate 3. ，
4, the overlapping fixed upper plates 3, 3 and bent heavy metal side plates 4, 4 formed on the rear edges of the same upper plates 3, 3 are rotated, and the overlapping fixed upper plates 3, 3 are bent over the upper plate 1. By superimposing the protective body on top of the protective body and fixing them with the fastening bodies 7, it is possible to assemble a protective body surrounded on three sides by the folded overlapping side plates 2, 4.4.

Next, the present invention will be described in detail below based on embodiments shown in the drawings.

First, as shown in Figure 2, the material, corrugated paper, is
The length in the left and right direction is the total length of the upper plate 1 and the overlapping fixed upper plate 3.3, and the length in the vertical direction is the upper plate 1, the outer plate 2a, the lower end plate 2b, the middle side plate 2C1, the upper end plate 2d, and the inner side plate 2e. A single rectangular piece of corrugated paper with a total length of
In this, cutouts 5, 5 for bending the upper plate and holes 6, 6 for bending the overlapping side plates are provided, and the overlapping fixing upper plates 3, 3 are raised by the fixing body 7. By fixing it to the plate 1, the inner ridge protector is assembled and formed.

That is, a lower end plate 2b and an upper end plate 2d are connected to one side of the upper plate 1, forming a folded and overlapping side plate 2 made up of three side plates: an outer plate 2a, a middle side plate 2C, and an inner side plate 2d, and On one side of each of the overlapping and fixing upper plates 3, 3, bent overlapping side plates 4, 4 having the same structure as described above are formed, and the above-mentioned upper plate 1 and the overlapping and fixing upper plates 3, 3 are overlapped and fixed. As shown in FIG. 1, the protective body is surrounded on three sides by bent heavy metal side plates 2, 4, and 4.

Next, the other side of the implementation shown in FIGS. 6 and 7 will be explained. This is by bending the overlapping fixed upper plates 3, 3 from the diagonal toward the overlapping side plates 2, 4.4, and It is constructed by engaging the ends of the plates 3, 3 with the side plates 2, 4.4, so that the upper surface of the inner ridge of the heavy packaged item a is aligned with the upper plate 1, as shown in FIG. The two overlapping fixed upper plates 3 and 3 formed by bending overlap with each other, thereby increasing the buffering effect and further protecting the inner ridge.

Therefore, when packaging an enamel bathtub a', which is an example of a heavy packaging item, using the inner edge protector of the present invention, first insert the buffer fixing body 9 into the cardboard outer box 8, as shown in FIG. , place the enamel bathtub a' suspended with a chain block or the like on this, fit two internal ridge protectors of the present invention on both left and right sides of the bathtub a', and finally attach the flaps of the cardboard outer box 8. Close it to complete the packaging.

As shown in FIGS. 4 and 5, the inner edge of the enamel bathtub a' wrapped in this way is protected against external forces from the sides by the outer plates 2a, 4a and the middle plates 2c, 4c. , the buffering force of the folded and superimposed side plate 2.4.4 consisting of the inner plates 2e and 4e absorbs the external force before it reaches the internal enamel bathtub a', protecting the inner ridge of the bathtub a', and As described above, the inner edge of the enamel bathtub a' can be protected against external forces from the upper plate 1 and the overlapping fixed upper plate 3.

Furthermore, since the inner ridge protector of this proposal is formed from a continuous piece of corrugated paper and folded many times, it has sufficient strength and will not be deformed or damaged by external force. It's something that doesn't exist.

The buffering properties against external forces and strength of these contents are based on the results of a drop test conducted by the present inventor, and as mentioned above, all were satisfied.

In addition, as for the type of corrugated paper, double-sided corrugated paper is used in the enamel bathtub a', but it is not limited to this, and double-sided corrugated paper can be used when lighter weight and high cushioning properties and strength are not required. You may also use 1. Further, if the material is heavier and requires high cushioning properties and strength, three-layer corrugated paper may be used.

Since the present invention is configured as described above, a sufficient cushioning effect can be exerted using only corrugated paper as a material, and the inner edge of the packaged heavy object a can be reliably protected.

In addition, since there is only one part, there is no wastage of material, and it is easy to process, the buffer fixing body can be manufactured at low cost.Furthermore, the assembly is simple, just by bending and fixing, so it has practical effects. is a large one.

Furthermore, since the material is only corrugated paper, it can be disposed of by incineration, and there are no disposal problems like with styrofoam.
