In Patent Document 1, a sheet of corrugated cardboard is folded to form a rectangular support tube, and the front end portion of an adhesive plate located inside the support tube is bent along the fold line to form a brace plate. , a shock absorber in which the strength of the support tube is improved by bringing the tip of the brace plate into contact with the inner corner of the support tube.

In the above Patent Document 2, a sheet of corrugated cardboard is folded to form a rectangular tube, and in this rectangular tube, a central reinforcing piece having a length forming a diagonal line and both sides of the central reinforcing piece are divided. The reinforcing pieces on both sides of the central reinforcing piece are bent so that the diagonal lines intersect each other in an X-shape in the square cylinder, and the tips of these central and both side reinforcing pieces are attached to the side walls. A receiving cushioning material for packaging is described which is brought into contact with the corners of a part to improve shape retention, cushioning and compression resistance.

In the prior art of Patent Document 1, since the brace plate is only on one side of the diagonal line of the square with respect to the support cylinder, it is difficult to reduce the deformation due to the pressing force acting obliquely from the direction without the brace plate. In addition, since the bracing plate is manufactured by bending the tip over the entire length of the support cylinder, the dimensions of the required corrugated cardboard tend to be large, and the material cost tends to be high. Furthermore, since the braces are produced at the bent portion of the tip forming the support tube, the direction and arrangement of the braces are restricted.

In the prior art of Patent Document 2, both side portions of the tip portion forming a rectangular tube are bent as reinforcing pieces to form a brace plate, and the central portion is notched halfway and then perpendicular to the reinforcing pieces on both sides. It is used as a central reinforcing piece by bending it so that it does. As a result, the size of the corrugated cardboard sheet tends to be larger than that of a normal rectangular support tube, and the manufacturing cost and material cost tend to increase.

Accordingly, there is a need for a support member for packaging that has high strength without increasing the size of the structure from conventional members.
