To facilitate such cutting, a cut tape may be joined to the connecting piece 21 or perforations may be formed. Since the packaging boxes 31 and 32 are separated by being divided, the number of products per lot can be reduced.

Further, such a packaging box can be opened without being divided. That is, as shown in FIG. 6, the cover plate 25 is cut by the cut tape 28 at the center thereof.
It should be noted here that the flap 27 is left uncut. Then, the perforations 30 of the flap 27 are broken. Then two packaging boxes 31, 32
Holds a state in which the flap 27 is connected to each other by the connecting piece 21 and a portion of the flap 27 on the tip side of the perforations 30. Moreover, the cover plate 25 is opened by the cut tape 28 and the perforation 30. The packaging boxes 31, 32 thus opened are resealed by inserting the base end side portions of the flaps 27 on both sides of the lid plate 25, which are broken by the perforations 30, into the side flaps 14. It becomes possible to do. Note that such opening may be performed after the two packaging boxes 31, 32 are divided from each other, whereby the normal opening is performed.

Further, the upper part of the packaging box can be removed to form a display case as shown in FIG. That is, the side surface flap 14 and the side plates 12 and 13 are broken at an intermediate position in the height direction by using the cut tape 15 extending laterally at the M-shaped notch 16 and the perforations formed on the side plate 13 are cut. By removing the side surface flap 14 and the upper flap 18 above the cut tape 15 by means of 19, the configuration shown in FIG. 7 is obtained. According to such a configuration, it is possible to form a display case with the lower parts of the two packaging boxes 31 and 32 connected to each other. Needless to say, the display case in a divided state can be obtained by separating the two packaging boxes 31 and 32 and then removing the upper portions thereof.

As described above, the packaging box according to the present embodiment can be opened by opening the cover plate 25 before or after the division, and can be re-opened by the flap 27 at the base end side of the perforations 30. Sealing is possible. Further, the display case can be assembled before and after the division. Further, since the flap 27 of the cover plate 25 has a length of approximately 2/3 of the height of the box, the connecting strength at the time of connection increases. Moreover, 2 by the connecting piece 21

Therefore, the strength of such a side wall portion is increased, and the packaging box has high buckling strength. Moreover, even if the side surface flap is cut at the second cutting guide portion, the tip side portion maintains a state in which it is glued or adhered to the side wall, so that high strength is maintained even after opening. . Further, even when the packaging boxes connected by the first cutting guide means are separated from each other, the side flaps maintain the above high strength because they are kept glued or adhered to the side wall. .

Further, in such a split-type packaging box, the second cutting guide portion of the side flaps provided on both sides of the lid plate is cut, and the lid plate is split at each split position by the first cutting guide portion. This makes it possible to open it. Such unsealing can be performed both before the division and after the division. Moreover, by inserting the side flaps on both sides of the once opened lid plate, which are on the root side of the area to be glued or adhered and which remains on the root side of the second cutting guide portion, into the corresponding side walls. It becomes possible to reseal. That is, after opening before or after division, it becomes possible to arbitrarily reseal again.

Further, the packaging box according to the present invention is provided with the third cutting guide portion so as to laterally cut each packaging box along the abutting position of the front end of the side flap and the front end of the bottom flap. In addition, it is possible to laterally cut each packaging box along this cutting guide part, remove the upper side portion of each packaging box, and leave only the bottom plate and the lower side portions of the four side walls. Alternatively, it is also possible to leave the side plates arranged so as to overlap each other and to remove the upper part thereof. Therefore, by providing such a third cutting guide portion, the packaging box can be used as a display case, and even after the physical distribution stage is finished, the display box displays the product as the content. And then available for sale.
