  In the case of Patent Documents 1 and 2 of the background art, when opening, it is necessary to push the opening to a sufficient depth in order to cut the cutting line. However, in the case where the stored object is stored without a gap on the back side of the side surface, it cannot be pushed to a sufficient depth, and it is difficult to open. In addition, since the opening is pushed obliquely downward and inward from the lid piece, the opening that has been pushed inward obliquely downward at the time of opening must be pulled up and opened. However, it is difficult for a finger to slip and force to pull up the opening that has been pushed obliquely downward. In particular, when the stored items are stored without gaps, it is difficult to open the container by this lifting. Further, even when the contents are soft and may be damaged, they cannot be pushed strongly.

  In the case of opening the packaging box disclosed in Patent Literature 2, the above-mentioned difficulty in catching the finger is solved, but when the stored object is stored without a gap, it cannot be pushed in, and it is difficult to open by pulling up. The problem remains.

When opening this packaging box, the pushing part is pushed and slightly dented inside the packaging box. As a result, a step is formed between the lid piece and the side edge of the lid piece protruding, and the protruding side edge of the lid piece is pulled up to cut the breaking line and open the package.

  A short uncut portion is provided between the breaking line and the cutting line for opening. A pair of the cutting line for opening is provided, and the pair of cutting line for opening is provided substantially parallel to each other at a distance enough to allow a user's finger to enter, and is included in the pushing portion of the breaking line. At the position, one long all-cut line is provided.

  The packaging box of the present invention has a simple structure, and can be easily opened only by pushing the side face shallowly. In particular, even if the contents are in contact with the back surface of the side surface without any gap, it is possible to form a clue when pulling up the lid piece by just slightly pressing the pressing portion located at the end near the lid piece on the side surface. . Furthermore, the tearing line located between the lid piece and the side surface can be cut while lifting the lid piece while holding the clue, and can be easily opened.
