  TECHNICAL FIELD The present invention relates to a structure of a rain gutter cushioning material, and more particularly, to a cushioning material technology for packaging so as not to damage the rain gutter.

  Conventionally, the structure of patent document 1 is known when packing a rain gutter. According to Patent Document 1, as shown in FIG. 5, the structure of the eaves basket 1, which is a rain gutter, is slightly inclined inwardly on the side wall 3 reaching the outdoor-side ear 1 c, and on the side wall 3. The bottom straight portion 10 and the side straight portion reaching the inner ear portion 1a form an L-shaped side wall, and the curved and inclined side wall 3 and the L-shaped side wall form one eave. The ridge 1 is formed in a substantially C-shaped cross section.

  Then, by arranging the two eaves 1 and 1 in a point-symmetric manner so that the upper openings 2 of the eaves 1 face each other inwardly, the curved inclined side wall 3 of one eaves 1 is provided. Is inserted into the upper openings 2 and 2 so as to face the cross-sectional L-shaped part of the side wall of the other eaves 1, so that the two eaves 1 and 1 are viewed from the end face in a substantially square shape. The shell-shaped portion 4 is formed into a shape.

  Such shell-like portions 4 and 4 are stacked in two upper and lower stages between the straight portions 10 and 10 at the bottom via partition cardboard 7, and protective materials 5 and 5 such as polystyrene foam having a substantially U-shaped cross-section are placed vertically. The four eaves baskets 1 are packed in a cardboard box 6.

With this configuration, the shell-like portion 4 that is formed into a shell (shell) shape with the pair of eaves 1 and 1 is shell-like without being filled with a protective material, and is sufficiently strong against external force. By disposing the protective material 5 around the portion 4, it is possible to sufficiently withstand shocking external forces.
