As shown in FIG. 14, a support surface 32 c that supports the corner portion of the bonnet is formed, the connection portion 32 d is connected to the connection groove 31 f of the support portion base 31, and the fitting hole 32 e is connected to the support portion base 31. When fitted to the steep slope protecting portion 31 h that protects the steep slope side, the support portion main body 33 that connects the support portion base 31 and the support portion 32 is completed.

In the case of the third embodiment, the support unit base 31 is configured so that the half-shaped corrugated paper 31j extended symmetrically on one side of the corrugated paper 31a is folded before the corrugated paper 31a is folded in two. Since it is inserted and folded between the two-fold corrugated paper 31a and folded and folded in three so as to sandwich the half-shaped corrugated paper 31j, the thickness of the steep slope protecting portion 31h is larger than the thickness of the steep slope protecting portion 11h of the first embodiment. Become thicker. Therefore, the size of the fitting hole 32e drilled in the support portion 32 is made larger than the fitting hole 12e drilled in the support portion 12 of the first embodiment.

Further, when the corrugated cardboard 31a and the half-shaped corrugated paper 31j are folded in three and folded, the substantially U-shaped defect portion 31k provided on the gentle slope side of the two-fold corrugated paper 31a, the half-shaped corrugated paper 31j The gentle slope side is notched in a J-shape by the missing portion 31m provided on the gentle slope side.

When the support body 33 is accommodated inside by opening the lid of the upper surface 34 a of the body housing portion 34, the support surface 32 c of the support portion 32 is supported by the inclined surface of the support portion base 31 and the support portion base 31 is loosened. Due to the widths of the slope protection part 31g, the steep slope protection part 31h and the support part 32, the support part main body 33 is accommodated in the main body accommodating part 34 without a gap, and the packaging protection member 30 shown in FIG. 13 is assembled.

The packaging protection member 30 assembled in this way has the following effects. As described above, the support portion main body 33 in which the support portion base 31 and the support portion 32 are connected is housed in the main body housing portion 34. The support part base 31 and the support part 32 are connected by connecting the connection part 32 d of the support part 32 to the connection groove 31 f of the support part base 31 and the steep slope protecting part 31 h of the support part base 31. This is done by fitting into the fitting hole 32e.

The support base 31 folds the half-shaped corrugated paper 31j, which is symmetrically extended on one side of the corrugated paper 31a, before the original corrugated paper 31a is folded in two and folded. When the sheet is inserted and folded between the two and folded in half so as to sandwich the half-shaped corrugated cardboard 31j, a thick slope 31b and steep slope 31c are formed. On the other hand, when the support portion 32 is bent along the gentle slope 31b and the steep slope 31c of the support base 31 with the substantially center 32b of the substantially rectangular corrugated cardboard 32a forming the base as the bottom, the corner portion of the bonnet is formed. A support surface 32c that supports the substrate is formed.

Since the support surface 32c of the support portion 32 is supported by a slope formed by the three-folded gentle slope 31b and the steep slope 31c of the support base 31, the strength that reinforces the central portion where the weight of the automobile bonnet is most loaded. Is sufficiently obtained.

Further, the high slope side is protected by a gentle slope protection part 31g formed by folding the corrugated cardboard 31a forming the original shape of the support base 31 into three, and the low slope side is protected by the steep slope protection part 31h. Therefore, it is not necessary to protect the high side and the low side with separate parts.

Further, the support base 31 folds the half-shaped corrugated paper 31j, which is symmetrically extended on one side of the corrugated paper 31a, before the original corrugated paper 31a is folded in two. Since it is inserted between the paper 31a and folded, and folded in three so as to sandwich the half-shaped corrugated cardboard 31j, the thickness is increased and the base of the support base can be strengthened.

Further, when the corrugated paper 31a and the half-shaped corrugated paper 31j are folded in three, the substantially U-shaped chipped portion 31k provided on the gentle slope side of the two-fold corrugated paper 31a, the semi-shaped corrugated paper 31j Because of the missing portion 31m provided on the gentle slope side, the gentle slope side is cut out in a J-shape, so that the holding strength can be adjusted.

When the corrugated paper 31a and the half-shaped corrugated paper 31j are folded in three due to the shape of the missing part 31k of the half-folded corrugated paper 31a and the defective part 31m of the half-shaped corrugated paper 31j, The missing part that cuts out the slope protection part is not limited to a J shape as long as the holding strength can be adjusted.

The operation | work which packs the bonnet for motor vehicles using the packaging protection member 30 assembled in this way is demonstrated.

When storing the bonnet for an automobile in a vertical position, the packing protection member 30 is arranged face-to-face with the gentle slope 31b side inward, and the left and right corners on the window side are formed in the upper surface 34a of the main body housing part 34. It inserts into the inserted insertion hole 34b (FIG. 23). By doing so, the corner portion of the automobile bonnet is encased in the slope composed of the gentle slope 31b and the steep slope 31c of the packaging protection member 30, so that the weight of the automobile bonnet can be supported. Further, if the entire bonnet is wrapped by the packing box 105 (FIG. 22), it can be stored side by side in the vertical direction.

The above description shows the structure of the packaging protection member when storing the hood in a substantially flat state, but the front rim of the hood is bent in a vertical position with the front edge of the hood bent toward the tip. In order to store, if the packaging protection member 10 (FIG. 1), 20 (FIG. 7), 30 (FIG. 13) as described above is used, the packaging box 105 becomes unstable. In that case, it is necessary to prevent the spacer from moving in the packing box adjacent to the packing protection member.

In the case where the front edge of the bonnet is bent relatively little, as shown in FIG. 19, a rectangular parallelepiped 15 formed by bending a substantially rectangular corrugated cardboard is used as a simple spacer and adjacent to the main body accommodating portions 14, 24, and 34. It can be solved by installing it.

Further, when the front edge of the bonnet is bent greatly, as shown in FIG. 20, the bottom face 16a and the side face 16b of the rectangular parallelepiped 16 formed by bending a substantially rectangular corrugated cardboard are formed in the main body accommodating parts 14, 24, 34. It can be solved by fixing and installing it as a fixed spacer adjacent to the main body accommodating portions 14, 24, 34.

As described above, according to the packaging protective member for an automobile bonnet of the present invention, the protective member for protecting the corner portion of the bonnet can be reliably reduced by reducing the cost and weight and improving the holding strength. It is possible to provide a packaging protection member for an automobile bonnet that can be packaged in a package.
