Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box with a cushioning material.

[0002]

2. Description of the Related Art When packaging a product which needs to avoid impact and mechanical pressure, it has been conventionally practiced to use a styrofoam cushioning material to support the upper and lower portions of the contents inside a packaging box. There is.

[0003]

However, the styrofoam, which has been widely used as an internal cushioning material for packaging boxes, is
Disposal after the product was put out was troublesome, and there were many problems in terms of waste disposal.

An object of the present invention is to provide a packaging box with a cushioning material which has an excellent function of protecting contents from impact and mechanical pressure and which can be easily disposed of.

[0005]

DISCLOSURE OF THE INVENTION The present invention is a packaging box consisting of a side wall portion surrounding the contents and both bottom and top closing portions, and a cardboard for supporting the upper and lower portions of the contents inside the box. The present invention provides a cardboard-made cushioning material-equipped packaging box in which a pair of cardboard-made cushioning materials each having a cylindrical double winding are arranged.

In this cardboard-made cushioning box with cushioning material, a handle is attached to the upper surface of the cardboard-made cushioning material that supports the upper portion of the contents, and the handle is projected upward from the opening of the upper closed portion of the packaging box. Can be allowed to.

The packaging box body may be formed by folding a paper blank.

The corrugated cardboard cushioning material is preferably a first paperboard, a first paperboard having a corrugated cross section, a second paperboard, and a second paperboard and a second paperboard having different corrugation specifications from the first paperboard. It is made of corrugated cardboard having a double structure in which the paperboard of No. 3 is sequentially laminated and adhered to each other.

[0009]

[Function] The contents are stored in a packaging box with the upper and lower parts supported by corrugated cardboard with a double winding structure.
Protected from external shocks and mechanical pressure. Further, the packaging box containing the contents can be carried by holding the handle attached to the upper surface of the cardboard cushioning material. The handle is attached to the cardboard cushioning material, and it is easy to secure the attachment strength.

After the contents are taken out, the cardboard cushioning material can be disassembled and discarded as combustible waste. Also,
If the packaging box consists of paper blanks, this too is easy to disassemble and discard.

The corrugated cardboard cushioning material includes a first paperboard, a first paperboard having a corrugated cross-section, a second paperboard, a second paperboard having a corrugated specification different from that of the first paperboard, and a third paperboard. The cardboard having a double structure in which the paperboard and the paperboard are sequentially laminated and adhered to each other has a particularly large cushioning effect.
