It consists of two connecting plates 20, 20 which are arranged in series. The packaging box 10 is almost the same as that shown in the description of the conventional example, and detailed description is omitted, but in the present invention, slits 131, 13 are provided at both ends.
Lid flap 12 connected to side wall 13 provided with 1
The corners 121, 121 at both ends of the upper edge are rounded to make it easier to insert the connecting plate 20 into the packaging boxes 10, 10, and the tip 132 of the slit 131 strengthens the connection between the packaging boxes 10, 10. The slit 131 has a notch 11 at the upper end to facilitate division into the packaging boxes 10, 10.
1 is provided, and unique innovations have been made. The connecting plate 20 connects the overlapping side walls 1 of the packaging boxes 10, 10.
A slit 200, which is inserted across and engaged with the slits 131, 131 at one end of each of the slits 3 and 13, opens downward. The groove width of the slit 200 is the width of the packaging box 1.
When the thickness is slightly smaller than the thickness of two cardboard boxes 0 and inserted across the packaging boxes 10 and 10 to be connected,
It is desirable to be able to engage firmly. Above the slit 200, there is a tape 201 at a position continuous with the slit 200 and two perforations on both sides of the tape 201.
