Packaging Material

Abstract

Disclosed is a packaging material having a plurality of angular cylindrical structures built up by folding a piece of a corrugated cardboard material, comprising: a fitting-in concave portion to fit a predetermined object to be packaged therein, the fitting-in concave portion being formed by being surrounded by the angular cylindrical structures; an opening portion to house a first accessory inside the packaging material, the opening portion being formed by folding a surrounding end piece of an opening formed by cutting out a portion of one surface of the packaging material, toward an inside of the packaging material; and a notch-shaped concave portion to house a second accessory, the notch-shaped concave portion being formed by concaving one of convex angle portions of the packaging material toward the inside.

1 . A packaging material having a plurality of angular cylindrical structures built up by folding a piece of a corrugated cardboard material, comprising:
 a fitting-in concave portion to fit a predetermined object to be packaged therein, the fitting-in concave portion being formed by being surrounded by the angular cylindrical structures;   an opening portion to house a first accessory inside the packaging material, the opening portion being formed by folding a surrounding end piece of an opening formed by cutting out a portion of one surface of the packaging material, toward an inside of the packaging material; and   a notch-shaped concave portion to house a second accessory, the notch-shaped concave portion being formed by concaving one of convex angle portions of the packaging material toward the inside.   
   
   
       2 . A packaging material having a plurality of angular cylindrical structures built up by folding a piece of a corrugated cardboard material, comprising:
 a fitting-in concave portion to fit a predetermined object to be packaged therein;   an opening portion to house a first accessory inside the packaging material, the opening portion being formed in one surface of the packaging material; and   a notch-shaped concave portion to house a second accessory, which is formed in one of angle portions of the packaging material.   
   
   
       3 . The packaging material of  claim 2 , wherein the opening portion is formed by folding a surrounding end piece of an opening formed by cutting out a portion of the surfaces, toward an inside of the packaging material. 
   
   
       4 . The packaging material of  claim 2 , wherein the notch-shaped concave portion is formed by concaving the one angle portion toward an inside.
