In addition, the outer box 5 is preferably formed with a folding line (not shown) for storing in a folded and flat state.

As shown in FIG. 1, the internal board 1 </ b> A includes an installation board 2 formed in a rectangular shape and a presser film 3 having flexibility.
The installation board 2 is a plate-like member on which an article to be packed (hereinafter simply referred to as “article”) is placed, and is not particularly limited, but is made of a material such as paper or synthetic resin that is rigid enough to be bent. It is formed by.

At both end portions 15 in the longitudinal direction of the installation board 2, a first fold line 16 is provided substantially along the short side 2 a. Specifically, the first fold line 16 is provided at a position where the distance from the short side 2a is substantially the same as the height dimension of the side surface portion 7 of the outer box 5 shown in FIG.
The installation board 2 is valley-folded at the first fold line 16 so that the end 15 on the outer side of the first fold line 16 is the surface (hereinafter referred to as “upper surface”) 18 on which the article X is placed. It can be bent to the side to stand.

  The first fold line 16 is slightly bent into the shape of “<” or “>” so as to protrude to the outside of the installation board 2, that is, the short side 2 a side in the intermediate portion in the extending direction. The bending angle θ1 of the first bending line 16 with respect to the virtual line L1 parallel to the short side 2a is 1 degree or more and 3 degrees or less, preferably 1.5 degrees or more and 2.5 degrees or less, and most preferably 2 degrees. In other words, the angle θ2 formed by the first fold line 16 is 174 ° C. or higher and 178 ° C. or lower, preferably 175 ° or higher and 177 ° C. or lower, and most preferably 176 °.

The presser film 3 is a film made of a synthetic resin having flexibility and stretchability, and is formed in a transparent or translucent manner, although it is not essential.
The presser film 3 is arranged in the longitudinal direction of the installation board 2 over a position closer to the center than the first fold line 16 of the installation board 2, and in the short direction, an end near the long side 2b is provided. It is arranged so as to cover almost the whole, leaving a little.

The tension of the presser film 3 with respect to the installation board 2 is such that the presser film 3 can be opened easily with a slight slack so that the presser film 3 does not loosen or has almost no wrinkles. .
The end 3 a of the presser film 3 disposed along the short direction of the installation board 2 is not attached to the installation board 2 but is an open end. On the other hand, an end portion 3b of the presser film 3 arranged along the longitudinal direction of the installation board 2 is provided with an adhesive portion S, and the adhesive portion or the adhesive is attached to the installation board 2 at the adhesive portion S.
