Description

  The present invention relates to a tatami paper type packaging sheet capable of efficiently packaging products of different sizes and products of different quantities, and a resizeable box assembled from the sheets.

In recent years, there are increasing opportunities to order and purchase various products by telephone, the Internet, catalogs, and the like. The products sent by mail order dealers etc. to buyers and their quantities vary depending on the order contents, so the dealers must prepare many types of shipping boxes (cardboard boxes) according to the packing quantity. I must.
However, the fact that many types of shipping boxes have to be prepared increases the cost and the storage space for the shipping boxes becomes a problem. Further, when the size of the shipping box is larger than the product to be shipped, a cushioning material is required to fill a useless space generated inside. The heavy use of cushioning materials increases costs and dislikes giving customers a bad image of overpackaging.

Conventionally, a large number of resizeable boxes that can change the width, depth, and height of the box according to the shape and quantity of the package are known, for example, as shown in the following documents 1 to 9. However, since these conventional ones change the size (volume change) by bending a highly rigid box side wall, etc., in the case of a transport box formed of thick paper such as cardboard, the box side wall It is not easy to bend them, and there is a restriction that the degree of freedom of dimensional adjustment is low.
And since all the types of the conventional corrugated cardboard boxes are formed of a type called A type (JIS Z-1507), a box type other than the A type is desired.

On the other hand, traditionally, tatami paper has been known as a form of covering folded clothes from all sides and tying them with a string or string (published by the World Encyclopedia, Heibonsha).
And the shape of the box which applied such tatami paper is described in the following nonpatent literature 1.
