Japanese Patent Application Laid-Open No. 2009-249023

Since the packaging box of Patent Document 1 supports the corners with the window side of the bonnet facing down, the support members must conform to the complicated shape of the corners, and thus support a large load. need to be strengthened. Moreover, the size and shape of each car model are different, and various packaging boxes with different sizes and thicknesses must be produced. In particular, since the dimensions of the corner portion differ depending on the type of vehicle, there is a problem that there are few cases in which the support member can be shared, and there are many kinds of support members.

SUMMARY OF THE INVENTION The present invention was developed in view of the above points, and an object of the present invention is to provide a packaging box capable of packaging hoods of as many vehicle models as possible.

In order to achieve the above objects, the hood packaging box of the present invention is configured as follows. That is, in a corrugated cardboard packaging box for storing and transporting vertically with the window side of the bonnet facing up, the packaging box is provided with a support at the center of the bottom for supporting one side of the flat or convexly curved surface of the bonnet. The support base is a rectangular parallelepiped that fits within the width of the packaging box, and has a V-shaped or inverted trapezoidal support portion on which a plurality of cardboard sheets are folded on the bottom plate. The slanted central portion of is formed to have a bulge .

In this packaging box, the bonnet is supported by a support base having a V-shaped or inverted trapezoidal support portion with one side of the flat or convexly curved surface of the bonnet facing downward. If the width of the lower side of the bonnet is thin, a V-shaped support is used, and if the tip portion is thick, an inverted trapezoidal support is used.
By preparing V-shaped and inverted trapezoidal support bases, the bonnets of most vehicle types can be accommodated. In addition, since the inclined central portion of the supporting portion is formed to have a slight bulge, it is possible to support even an object that is slightly curved in the longitudinal direction.

The support base is made by folding cardboard.
In this case, the V-shaped or inverted trapezoidal support is placed on the bottom plate after a plurality of folded cardboards to support the weight of the bonnet.

In addition, when the width of the packaging box is wide, the support stand is provided with an extension piece that can be folded to the back side of the bottom plate as described in claim 2 , and in the case of a wide packaging box, the extension piece is provided. should be expanded to increase the width dimension. In order to prevent the expansion piece from bending downward due to its own weight during expansion, it is preferable that the connecting position of the expansion piece is positioned inside the end of the support base and a raising piece is attached to the connecting portion.

On the other hand, the upper end of the bonnet may be fixed to the upper front wall or side plate piece of the packaging box with an adhesive tape, but in order to protect the two left and right corners, it fits within the width of the packaging box, It is desirable to provide a protective member having a triangular tubular shape in a side view into which the corner portion is fitted. Moreover, when this protective member is used for the wide packaging box of Claim 2, it is preferable to provide a spacer for eliminating the gap in the width direction.

The bonnet packaging box of the present invention is provided with a support at the center of the bottom for supporting one side of the flat or convexly curved surface of the bonnet, the support being a rectangular parallelepiped that fits within the width of the packaging box. Equipped with a V-shaped or inverted trapezoidal support, it can be used to wrap the bonnets of many car models.
In addition, it is assumed that the V-shaped or inverted trapezoidal support portion of the support base is arranged on a bottom plate on which a plurality of sheets of cardboard are folded, and that the central portion of the support portion is formed to have a bulge. The bonnet is sufficiently supported and can be easily flattened after use for convenient disposal.

In addition, as described in claim 2 , the support base has an extension piece that can be folded to the back side of the bottom plate so that it can be used for a wide packaging box. If the connecting position of the expansion piece is set inside the end of the support base so as not to bend, and a raising piece is provided at the connecting part, expansion and contraction can be easily performed, and the support base can be used for a narrow or wide packaging box. Can be used together.
