DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging structure for accommodating, for example, an indoor unit of an air conditioner.

[0002]

2. Description of the Related Art Conventionally, when packaging equipment such as an indoor unit of an air conditioner, a cushion made of polystyrene foam has been used as a buffer for protecting the equipment inside a packaging box.

However, recently, when a styrene foam buffer is incinerated after being used, pollution smoke is generated, and the incinerator is damaged by heat generated by incineration.
Due to the short life, etc., a buffer in place of a polystyrene foam buffer is being studied.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is easy to assemble using a corrugated cardboard for buffering and protecting a packaged object such as an indoor unit of an air conditioner. It is an object of the present invention to provide an excellent packaging structure.

[0005]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a cushion made of a corrugated cardboard which covers both longitudinal ends of an article to be packaged such as an indoor unit of an air conditioner. A tubular sleeve made of a corrugated cardboard that integrally covers the package and the buffer while covering both longitudinal ends of the package; the buffer is an outer buffer, and the outer buffer; And an inner shock absorber having a folding step which is set and inserted into both ends of the article to be packaged and conforms to the shape of both ends of the article to be packaged.

[0006] With this configuration, an article to be packaged, such as an indoor unit of an air conditioner, can be buffer-protected by a cushion made of a corrugated cardboard made according to the shape of both ends of the article to be packaged. The packaged object can be packaged by integrally covering the packaged object and the buffer with a tubular sleeve made of a corrugated cardboard while covering both ends in the length direction of the packaged object. Then, when the buffer or the sleeve is incinerated after use, there is no pollution smoke such as styrofoam or the incinerator is damaged by the heat generated by the incineration.
