In order to achieve the above-mentioned object, the present invention has a box 1 made of corrugated cardboard, cardboard or the like, and side plates 2 and 2 facing each other, which are connected to the side plates 2 and 2 in a freely bendable manner. Along the cover plates 3 and 3 that have been cut, cuts a and a are made in parallel in the vertical direction (the direction between the fold lines c and c of the cover plates 3 and 3 and the side plates 2 and 2) at a predetermined interval. Expansion piece 4, 4
And the fold lines b and b are provided in parallel with the fold lines c and c of the side plates 2 and 2 and the lid plates 3 and 3 on the lid plate portions 4a and 4a of the expansion pieces 4 and 4, and the lid plate of the box body 1 is formed. In the process of opening 3, 3, the expansion pieces 4, 4 project in a triangular shape on the back side of the lid plates 3, 3 so that the side plate portions 4b, 4b of the expansion pieces 4, 4 tilt to the outside of the side plates 2, 2. However, when the lid plates 3 and 3 are opened more than a predetermined amount, the gaps 5 and 5 suitable for inserting the hand A are formed above the side plates 2 and 2.

[0006]

In the packaging box of the present invention having the above construction, when the product B is put in or taken out of the box body 1, if the lid plates 3 and 3 are opened, both ends of the expansion pieces 4 and 4 are separated from the cuts a and a. Then, the upper ends of the expansion pieces 4 and 4 are slightly bent inward, and the lower ends thereof are slightly bent outward, and are bent from the folds b and b of the cover plate portions 4a and 4a. Therefore, when the cover plate is opened more than a predetermined amount, the expansion pieces 4 and 4 gradually protrude toward the back surface side of the cover plates 3 and 3 in a triangular shape, and
The side plate portions 4a, 4a of 4 are tilted to the outside of the side plates 2, 2 to form gaps 5, 5 between the product B and the expansion pieces 4, 4 into which the hand A can be inserted. The gaps 5 and 5 are covered by the lid plates 3 and 3.
When closed, the side plates 4b and 4b and the cover plates 4a and 4a of the expansion pieces 4 and 4 forming the gaps 5 and 5 are respectively formed into the side plates 2 and 4.
2 and the lid plates 3 and 3 are fitted again to become a part of the original side plates 2 and 2 and the lid plates 3 and 3, and are folded together with the lid plates 3 and 3 from the folds c and c, like a normal packaging box. Box 1
