[0003]

[Problems to be solved by the invention]

 Most of the above-mentioned conventional packaging cases are made of styrofoam material and have a history of several decades. However, this material has been found to have the following disadvantages due to long-term use. (1) Styrofoam is a highly toxic material, especially after burning, which is harmful to human health and significantly pollutes the environment. (2) Since the lower and upper cases made of styrofoam are thick except for the recesses that conform to the shape of the electrical product, they require a large amount of material and, if disposed after use, will be a major obstacle to environmental protection.

(3) In order to mold the lower case and the upper case, a large mold and a large injection machine are required, so that the production cost is high, and a toxic odor is generated in the process of heating and melting the polystyrene foam. This has a negative effect on the health of workers at the production site and harms the residents near the factory. (4) Styrofoam with a fluffy and coarse structure easily absorbs moisture, so precision electrical appliances and computers covered in a packaging case made of the foamed styrene absorb moisture during long-term storage or transportation. And may have a slight effect on its precision and service life.

(5) The density, strength and hardness of styrofoam differ depending on the unit weight. Smaller unit weights result in a coarser tissue, more prone to denting when subjected to impact or compression, and, in severe cases, to flake off and fail to completely protect the packaged product. On the other hand, if the weight is large, it is too hard to effectively absorb shock or vibration, and the cost increases. (6) When removing the Styrofoam packaging case from the carton and taking out the electrical products from the case, it is not possible to stack the packaging cases and reduce their volume, so a lot of space is required when transporting and storing the packaging cases. The cost of space required for transport and storage is high, which is disadvantageous for manufacturers.

(7) The four sides of the styrofoam packaging case are all flat and upright, and the dimensions are exactly the same as the inner size of the carton in consideration of the fixation of the electric product to be wrapped inside. Is a material with a high coefficient of friction, so that when entering the carton, the air below the lower case is difficult to flow out and it takes time for the lower case to reach the bottom of the carton, Pushing down with may cause the carton to break through, which can cause unnecessary and tedious things.

(8) When taking out the packaged electric product from the carton, it is not easy to take out the packaging case from the carton because the packaging case and the carton are tightly combined, and need the help of another person. It is inconvenient. (9) Since the upper case has a flat upper surface, the instruction manual for electric products and the accessory transformers, cords, plugs, etc. should be pushed into the gaps or wrapped in another way. You have to take care of it. If you do not know what accessories are present, the accessories may be thrown away when you throw away the packaging.

[0008] Accordingly, an object of the present invention is to provide a packaging case for an electric product which is molded from a tough, thin and light material, has a hollow shape having an air cushion effect, and can be stacked vertically and stored. .

[0009]

[Means for Solving the Problems]

[0010] A plurality of curved recesses are appropriately arranged on both sides of the four sides of the upper case and the lower case to reinforce the strength, and the very thin upper case and the lower case are provided with sufficient strength and elasticity. The packaging case can receive the shock and vibration that the packaged electric product receives during the lifting and lowering work during transportation, and protects the precision product perfectly. Therefore, the service life and precision of the electrical product can be ensured.

[0011] Furthermore, the four sides of the upper case and the lower case are formed in an inclined shape, and the inclination and the reinforcement of the above-mentioned curved recess make it possible to provide a sufficient air cushion for absorbing a shock after packaging, regardless of the direction. Has an effect. Therefore, when putting in the carton, the air in the upper case and the lower case can be pushed out and easily put into the carton by slightly pressing the bottom edge of the side, and the packaging work can be performed smoothly. Can proceed.

Further, since PP and PET do not absorb moisture, the precision electronic products packaged therein are not damaged by moisture during long-term transportation and storage, and their normal service life can be ensured. In addition, since the upper case has an open upper surface, place the product manual, accessory cords, plugs, batteries, etc. in the upward hollow part so that they do not move easily with protrusions etc. be able to. A cut line or hole was made in the side wall of the upper case, and the cut line or hole was fixed together with the accessory through the unique cord of an electric appliance or computer, and the top cover of the carton was opened. This is convenient because sometimes accessories are immediately visible.

[0013] As described above, when the upper and lower cases are overlapped, there is an effect of an air cushion having air therein, with sufficient strength and cushioning elasticity provided by the aid of a large number of curved dents, and the upper case is placed inside. It protects electronic products, such as precision computer products, packaged and packaged from shocks at all angles and prevents them from being damaged.
