Description

Packing buffer made of polyethylene terephthalate {CUSHION FROM POLYETHYLENE TEREPHTALATE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material for protecting a package from external impact when packaging an electronic product. Specifically, the present invention relates to a plurality of tube shapes made of polyethylene terephthalate (PET) and corresponding to the shape of the package and the packaging box. As a molded cushioning material, it functions as a cushioning material at the time of use, prevents damage to the product, and is easily collected and regenerated after use, thereby reducing the cost of logistics and environmental pollution.

In general, an electronic product such as a washing machine has a cabinet having an approximately square shape constituting the main body, and is packaged by a packing box so that the main body is protected when the manufacturer ships the electronic product. Careful attention must be paid to the robustness and safety of the packaging of such electronic products. If the packaging is not secured, the damage and breakage of the electronic products may occur, resulting in enormous economic losses. Therefore, the packaging standards of electronic products such as washing machines, etc. must pass a certain impact and drop test, and the development of new packaging technology and materials to meet this situation is urgently needed.

Looking at the example of the packaging method of such an electronic product based on Figure 1, the package 10 is accommodated in the receiving space 22 of the packaging box 20 is packaged. At this time, between the package 10 and the inner surface of the packaging box 20 is spaced a predetermined interval to protect the package 10 by the impact acting from the outside. At such intervals, a polystyrene foam (polystyrene foam) 30 called Styropol is provided as a buffer member that can absorb and cushion an impact. The foamed resin molded body 30 is provided so as to support the upper edge of the package 10, and the foamed resin molded body 30 is interposed between the upper edge of the package 10 and the packing box 20. As a result, the flow of the package 10 can be prevented and the shock can be buffered.

However, the packaging of the conventional electronic products as described above has a problem of waste of resources and environmental pollution due to the use of the foamed resin molded body 30. That is, the seller who sold the package 10 to a general household is recommended to collect and recycle the foamed resin molded body 30 again, but the recycling cost of collecting and recycling the foamed resin molded body 30 again is higher than that of the foamed resin molded body 30. Not only is higher than the cost, but also because the size of the foamed resin molded body 30 is relatively large, the storage space is largely occupied, and the collection rate is not so high. Therefore, the foamed resin molded body 30 is in a situation of being used as a one-time packaging material, and the waste of resources is largely generated.

On the other hand, when the foamed resin molded body 30 is processed together with the general garbage without separate collection in a general household, the foamed resin molded body 30 is embedded in a landfill or incinerated at an incinerator. However, the foamed resin molded body 30 is not only decayed, but also has a considerable problem in landfilling and incineration by generating pollutants during incineration, and thus, the use of the foamed resin molded body 30 is gradually regulated.

Despite such problems, packaging materials that can replace the foamed resin molded body 30 have not been developed, and thus the use of the foamed resin molded body 30 cannot be reduced. In addition, although the cushioning member of the paper material is used as the packaging material, in a relatively heavy electronic product such as a washing machine, the cushioning member of the paper material is not suitable for robustness and safety.

The present invention has been made to solve the conventional problems as described above, an object of the present invention is to provide a cushioning material for packaging to prevent the waste and environmental pollution of the recycling is increased.

A fifth aspect of the present invention is a cushioning material for protecting a package from an external impact when packaging an electronic product, the outer wall of which is formed so as to surround the upper edge of the package and is made of polyethylene terephthalate (PET) film and the outer wall It relates to a shock absorbing material composed of a tube-shaped upper corner member including an air inlet formed so as to inject or extract air in the air layer therebetween.

A sixth aspect of the present invention is a cushioning material for protecting a package from an external impact when packaging an electronic product, the outer wall of which is formed so as to surround the upper or lower edge of the package, the outer wall composed of polyethylene terephthalate (PET) film And it relates to a buffer member consisting of a tube-shaped upper corner member and a lower corner member including an air inlet is formed so as to inject or withdraw air of the air layer between the outer wall.

In the buffer according to the seventh aspect of the present invention, in the buffers of the first to sixth aspects, the thickness of the polyethylene terephthalate (PET) film is determined by the weight of the package. Specifically, when packaging a microwave oven having a weight of about 10kg to 30kg, the thickness of the PET film is preferably 0.2mm to 1.5mm, in the case of a washing machine or a refrigerator having a weight of about 50kg to 160kg, the thickness of the PET film It is preferable that they are 0.2 mm-3.0 mm.

In this case, in the case of packaging with only the lower and / or upper corner member, it is preferable to increase the thickness of the PET film as compared with the case using only the lower and / or upper member.

Hereinafter, preferred embodiments of the packaging cushioning material according to the present invention will be described in detail with reference to the accompanying drawings. 2 to 4 is a view showing for explaining the packaging cushioning material according to this embodiment.

First, as shown in FIG. 2, a box-shaped package such as the package 10 is accommodated in the receiving space 22 of the package box 20 made of paper material, and then packaged. The package 10 and the package box 20 are packaged. Between the inner surface of the) is provided a predetermined interval so that the package 10 is protected by the impact from the outside.

In addition, a packing buffer 40 is interposed between the upper portion of the package 10 and the packaging box 20. The buffer member 40 is a tubular member including an outer wall formed of a polyethylene terephthalate (PET) film and an air inlet formed to inject or extract air from the air layer between the outer wall.

The cushioning material 40 has a top plate 42 formed to surround the top of the package 10, a hole 42a is formed in the center of the top plate 42, and a package (at the bottom edge of the top plate 42). Edge support plates 44 for supporting the edges of 10) are each extended. An air inlet 46 for injecting air may be formed in one of the holes 42a in the center of the upper plate 42.

The cushioning material 40 accommodates the package 10 in the receiving space 22 of the packing box 20, and then supplies air to support the corner support plate 44 of the buffer material 40 at the corner of the package 10. When the injected shock absorbing material 40 is installed, the upper part of the package 10 is wrapped by the upper plate 42 of the shock absorbing material 40, and the edge of the package 10 is the edge support plate 44 of the shock absorbing material 40. While being supported by the predetermined distance is maintained between the inner package of the packaging box 20 and the package 10.

At this time, the edge support plate 44 of the cushioning material 40 is easily fitted in the gap by the compression deformation, it is possible to easily perform the packaging operation by the buffer material (40). On the other hand, when installing the cushioning material 40 so that the edge support plate 44 of the cushioning material 40 is supported at the corners of the package 10, the cushioning material 40 is installed in a state in which air is not completely injected into the cushioning material 40. It is possible to install the shock absorbing material 40 more easily. That is, in order to prevent the package 10 from flowing in the receiving space 22 of the packaging box 20, the edge support plate 44 of the cushioning material 40 must be tightly fitted in the gap. Accordingly, when the edge support plate 44 of the shock absorbing material 40, which has been partially drained, is inserted in the gap 34, and air is injected through the air inlet 46, the edge support plate 44 expands by the injection of air. While being tightly fitted in the gap 34, it is possible to perform the packaging operation more easily. Here, it will be convenient to use an air injector not shown for the injection of air through the air inlet 46.

Although not shown in the drawings, the upper and lower surfaces of the package 10 may be supported and fixed by the cushioning material 40. At this time, the shock absorbing material that supports and fixes the lower surface of the package 10 may have the same structure as the shock absorbing material 40. When the upper and lower surfaces of the package 10 are supported by the cushioning material 40, the shock applied to the package 10 can be absorbed much more safely.

In this case, the polyethylene terephthalate (PET) film of the cushioning material 40 is preferably determined by the thickness of the package, the weight, in particular, a light electronic product, such as a microwave oven with a total weight of about 10kg to 30kg When packaging, etc., the thickness of the PET film is preferably 0.2mm to 1.5mm, and in the case of a washing machine or a refrigerator having a weight of approximately 50kg to 160kg, the thickness of the PET film is preferably 0.2mm to 3.0mm. The thickness of the PET film is obtained through known impact and drop experiments.

In addition, according to another embodiment of the present invention, the four corner members each supporting one corner of the upper surface of the package by dividing the cushioning material 40 shown in FIGS. 2 and 3 with respect to the center hole 42a, respectively ( 50; see FIG. 4). The length of the edge of the package upper plate of the edge member 50 is sufficient to have a length of 1/4 to 1/3 of the length of the edge of the package, and the air inlet 46 is preferably provided in each of the edge members.

When the package 10 is packaged by the packing box 10 and the shock absorbing material 40 as described above, the shock applied from the outside is buffered by the absorbing action of the shock absorbing material 40, thereby effectively damaging and breaking the package 10. It is possible to ensure excellent robustness and reliability, such as being prevented.

In addition, when a seller who sells the package 10 wants to collect the buffer 40, when the air is extracted from the buffer 40 through the air inlet 46, the volume of the buffer 40 is minimized. The shock absorbing material 40 can be easily collected. In addition, the collected cushioning material 40 can be conveniently stored, and it is easy to transport, so that it will be easier to re-supply and recycle to the manufacturer of the package 10.

As described above, the cushioning material for packaging according to the present invention is excellent in the robustness and reliability of the packaging, the collection and recycling is high, there is an effect of reducing the logistics cost and environmental pollution.
