Description

  This invention relates to a packaging case for sheet metal products for automobiles. More specifically, it is a packaging case for curved plate-like products such as hood hoods and door panels of automobiles, and is a paper packaging box formed of corrugated cardboard or the like that is heavy and dislikes deformation during transportation. The present invention relates to a packaging case that can be held in a state where it has a sufficient buffering effect, has a simple structure, and can reduce packaging work and packaging costs.

  When transporting sheet metal products such as hood hoods, side door panels, and back door panels of automobiles, the products are transported in a state where the products are supported by cushioning materials, pads, etc. in the packing case. Cushioning materials, pads, etc. (hereinafter referred to as “inner materials”) enclosed in the case deform the panel parts due to external impacts during transportation or loading / unloading, or accidental drops, etc., resulting in dents. This is to prevent this. The enclosed inner material absorbs external impacts and supports the panel components so that they are stable without moving in the main body box. The sash portion of the door panel is protected by winding another packing member during transportation and fixing it with a tape (for example, refer to the following patent document).

However, in the conventional packaging method, the packaging case varies depending on whether the curved plate-like product accommodated in the box is a bonnet hood, a side door panel, or a back door panel. Also, whenever the dimensions and shape of the panel change, the inner material that supports the panel must be replaced. The inner material may be formed of a synthetic resin material such as polystyrene foam, but it has many problems in the global environment, such as manufacturing cost problems, recycling problems, and waste collection / treatment problems. Recently, paper products made of blanks punched from paper sheets such as cardboard have been used in many cases. However, since a plurality of blanks punched from cardboard or the like are combined, tens of kinds of inner materials must be prepared. As a matter of fact, 40-60 internal materials are generally required for hoods, side door panels, and back door panels. Therefore, the structure becomes complicated, so that setup is not easy. Moreover, when the use type and the number of points of use of the inner material increase, there are disadvantages that the packing work process including setup and management increases and the packing cost increases. In addition, it is necessary to assemble another packing member around the sash portion or the like during assembly and transport and fix it with tape, which increases the packing work and takes time.
As described above, conventionally, the production of the inner material is troublesome, the cost is increased, and the shape change of the hood hood and the door panel cannot be flexibly handled.

Therefore, when packing heavy and easily deformed curved plate-shaped products, the use type and number of internal materials are small, the workability of the packing can be improved, and a sufficient cushioning effect is provided, so that it is inadvertent during transportation and loading / unloading There is a demand for the development of a packaging case that can protect the curved plate-like product from being damaged or deformed even if it falls.
This device is a case that can easily package curved plate-like products such as hoods and door panels of automobiles, so that the product can be held in a stable state without moving in the box with a small amount of inner material. In addition, the case itself has a cushioning property, and even if the case is dropped, it is formed with a structure that prevents the bottom of the main body box from bottoming out by leg pieces that protrude below the bottom plate. The purpose is to propose a packaging case that prevents the impact from being transmitted to the internal product and protects it from the impact during transportation.

The packaging box of the present invention that solves the above problems is a main body box formed of a cardboard material such as a piece of cardboard, with either the front or the back opened, and a pair of left and right bundled in the main body box.

The main body box is provided with a rectangular flat plate partitioned by vertical and horizontal folds at the center of a blank that becomes a flat flat surface when unfolded, and a top plate or left and right side plates facing the four sides of the flat plate or A frame formed by connecting a bottom plate and a closing piece to each outside thereof, folding the left and right side plates, a top plate and a bottom plate with respect to the plane plate, and closing the closure piece and fixing the overlapping portion. A body box of shape,
At the bottom of the main body box, at least a pair of leg pieces are provided integrally with the left and right side plates so that they protrude downward from the bottom plate when assembled,
The leg piece has a structure in which the bottom portion of the main body box does not bottom out.

  The present invention is characterized in that a third leg piece is provided on the bottom plate between the leg pieces so as to protrude below the bottom plate when assembled.

  The bottom plate is structured to be bent into a V shape at the center.

  Further, a bottom reinforcing pad is laid inside the bottom plate.

  The side pad is composed of a substantially rectangular piece having a plurality of folds orthogonal to the longitudinal direction, and is folded so as to hold a substantially Z shape by valley-folding or mountain-folding the fold portion, and into a Z-shape. A set of held side pads is installed inside the left and right side plates of the main body box, and is interposed so as to sandwich the outer edge of the accommodated item.

When the main body box of the present invention is unfolded, it is in a flat flat state, and is set up after temporarily placing a heavy, easily deformable sheet metal product such as a bonnet hood on the flat flat plate. There are leg pieces projecting below the bottom plate at the bottom of the left and right side plates and the closing piece, and the bottom plate is bent into a V shape at the center to prevent shock absorption and displacement / movement of the product. .
The side pad is folded so that the small piece is folded or mountain-folded so as to maintain a substantially Z shape, and the outer edge portion of the product can be sandwiched by the small piece member that is bent and held in the Z shape. Has been.

  The present invention can hold a curved plate-like product such as a hood hood of an automobile with a minimum amount of inner material without moving in the packing case, and also provides cushioning to the packing case itself, so that the case can be dropped. In addition, since the bottom of the main body box does not bottom out due to the leg pieces, there is an advantage that it is possible to prevent the shock from being transmitted to the internal parts and to protect it from the shock during transportation.
