The packaging box 10 has the insertion flap 20 of the cover part 14 (top | upper surface) in the front surface 12, and the cover opening part 18 in the back surface 16. As shown in FIG. The insertion flap 20 is formed with slits 20a, 20b, 20c for inserting the lid opening 18 (FIGS. 2 and 3).
In addition, the side surface provided with the cover part 14 shall be called the front surface 12 in this application, and the side surface which forms the lid opening part 18 shall be called the back surface 16 in this application. In the drawing, the solid line portions representing the slits 20 a, 20 b, and 20 c are portions that are cut into the insertion flap 20.
In the packaging box 10, since parts other than the lid opening part 18 and the insertion flap 20 are well-known, detailed description is abbreviate | omitted.

The lid opening portion 18 includes a head portion 18a inserted into the slits 20a, 20b and 20c of the insertion flap 20, a neck portion 18b formed continuously with the head portion 18a, and a separation portion formed continuously with the neck portion 18b. 18c. The head portion 18a and the neck portion 18b are formed by slits (cuts) in the back surface 16 of the packaging box 10, and the separating portion 18c is formed by perforations.
The neck portion 18b is formed smaller (or narrower) than the width of the head portion 18a and the separation portion 18c, and a space 19 is provided between the head portion 18a and the separation portion 18c. Further, the head portion 18a is formed so as to protrude from the neck portion 18b (hereinafter, the head portion 18a protruding from the neck portion 18b is referred to as “an overhang portion 22”).
In the figure, the solid line portion representing the cut drawn on the back surface 16 forms the head portion 18a and the neck portion 18b, and the dotted line portion representing the perforation 16a forms the separation portion 18c.

A fitting groove 21 into which the neck portion 18b is fitted is formed in the slit 20b of the insertion flap 20. The slits 20 a and 20 c are formed horizontally on the insertion flap 20, and the slit 20 b (the central portion of the slit of the insertion flap 20) is formed so as to protrude in the opposite direction of the lid portion 14. The fitting groove 21 is a space formed by the horizontal portions 20 a and 20 c of the slit of the insertion flap 20 and the central portion (raised portion) 20 b.
The width W1 of the fitting groove 21 is set to be equal to or wider than the width W2 of the neck portion 18b (W1 ≧ W2).

The neck portion 18b is formed smaller than the width of the head portion 18a and the separation portion 18c, and a space 19 is provided between the head portion 18a and the separation portion 18c. Thereby, when the head 18a of the lid opening part 18 is inserted into the slits 20a, 20b, 20c of the insertion flap 20, the head 18a is not locked to the edges of the slits 20a, 20c of the insertion flap 20.

That is, the neck portion 18b is fitted into the fitting groove 21 or is in a depressed state (FIG. 3B). When the neck portion 18 b is fitted into the fitting groove 21, the head portion 18 a is locked to the slit 20 b that forms the fitting groove 21. Even if the lid 14 is opened (or the insertion flap 20 is pulled out), the width W4 of the head 18a is formed larger (or wider) than the width W1 of the fitting groove 21, so the head 18a. The overhanging portion 22 is caught in the fitting groove 21, and the head portion 18a does not escape from the gap of the slit 20b.
Thus, when the head portion 18a of the lid opening portion 18 passes through the back side of the insertion flap 20, the neck portion 18b fits into the fitting groove 21 and the head portion 18a engages with the fitting groove 21. Even if the insertion flap 20 is pulled out from the lid opening portion 18 to be opened, the head portion 18a of the lid opening portion 18 is caught in the fitting groove 21 and cannot be pulled out from the slit 20a (FIG. 3B). Thereby, it becomes possible to provide the packaging box 10 with a function of reliably preventing opening.
The shape of the head portion 18a of the lid opening portion 18 is preferably an elliptical shape whose major axis is longer than the minor axis. However, the shape is not limited to this shape, and the head portion 18a (projecting portion 22) that projects from the neck portion 18b is used. What is provided is sufficient.

As described above, according to the present invention, the head portion 18a is not locked to the edges of the slits 20a and 20c of the insertion flap 20, and the lid portion is engaged with the head portion 18a and the fitting groove 21. Since 14 can be closed, the packaging box 10 can be provided with a function of reliably preventing opening.
Note that the width W3 of the slits 20a, 20b, 20c of the insertion flap 20 is set to be the same as or wider than the width W4 of the head 18a of the lid opening portion 18 (W3). ≧ W4). Thereby, the insertion of the head portion 18a of the lid opening portion 18 into the slits 20a, 20b, and 20c can be easily performed.

In the packaging box 10 of FIG. 1, when sealing the lid portion 14, the head portion 18 a of the lid opening portion 18 is inserted into the slits 20 a, 20 b, 20 c of the insertion flap 20, and the insertion flap 20 is inserted into the back surface 16. Insert inside.
On the other hand, when opening the lid portion 14 of the packaging box 10, the separation portion 18 c is separated from the back surface 16 along the perforation 16 a of the back surface 16. When the separation portion 18c is separated from the back surface 16, the lid portion 14 is opened. Even if the insertion flap 20 is inserted inside the back surface 16 again and sealed, the separating portion 18c of the lid opening portion 18 is separated from the back surface 16, so that it is clear that the packaging box 10 has already been opened. become.
