  By the way, as for the packing material which packs large products, such as the outdoor unit of the multi-type air conditioning apparatus for buildings, it is desirable to be comprised from several assembly members like patent document 1. FIG. This is because when a packaging material for a large product is composed of a single assembly member, the assembly member itself is also large, and handling such a large assembly member is not limited to an operator who performs the packaging work. This is because the burden of the increase is increased.

  Therefore, when trying to pack a large product using a packaging material composed of a plurality of assembly members, this time, even if the dimensions of the assembly members were strictly calculated, the number of workers, especially, In the case of one person, it may be difficult to assemble the assembly member precisely as designed, and the quality of the finished product may not be maintained. The same applies to unskilled workers. When the low-quality packing is done in this way, the packing material may not exhibit the tolerance as designed, and for example, a defect may occur such that the packing is unwound when the product is transported. However, increasing the number of workers unnecessarily is not a good idea from the viewpoint of labor costs.

  An object of the present invention is to provide a packaging material for large products that can be easily assembled into an orderly shape and a packaging method using such a packaging material.

The packaging material which concerns on 1st invention is a packaging material which packages a large sized product, Comprising: A top | upper surface member and a side member are provided.

The side member is separate from the top member, and covers the side of the large product while being suspended from a predetermined position of the top member.
This packing material is a packing material used for packing large products such as outdoor units of multi-type air conditioners for buildings. Generally, when a large product is packed with a packing material in which a top member that covers a top surface of a product and a side member that covers a side surface are integrally molded, it is easy to take time for packing work. Therefore, in this packing material, the top member and the side member are separated. And in this packing material, a side member is suspended by the predetermined position of a top | upper surface member. That is, the side member is aligned with an appropriate position of the top member. Thereby, the packaging material for large products can be easily assembled into an orderly shape.

The packaging material according to the second invention is the packaging material according to the first invention, wherein the top surface member has one of an opening or an insertion portion, and the upper portion of the side member has an opening or an insertion portion. The other is formed. The side member is maintained in a state of being hung at a predetermined position of the top member by inserting the insertion portion into the opening.
In this packing material, an opening is formed in the top surface member, and an insertion part to be inserted into the opening is formed in the upper part of the side member, or an opening is formed in the upper part of the side member, and An insertion portion to be inserted into the opening is formed in the surface member. At this time, the position where the opening and the insertion portion are formed is adjusted so that the top surface member and the side member have a predetermined positional relationship in a state where the insertion portion is inserted into the opening. That is, the side member is suspended at a predetermined position of the top member only by inserting the insertion portion formed on one of the upper part of the side member or the top member into the opening formed on the other. Thereby, in this packing material, a side member can be easily aligned with the appropriate position of a top surface member.
