  In the configuration of the conventional transport box for cut flowers described in Patent Document 1, the closed state is maintained by inserting the insertion tongue piece of the top plate that is finally closed into the insertion hole of the end flap. However, since the insertion tongue piece is only inserted into the insertion hole, there is a problem that the complete locking state is not maintained and the top plate is lifted.

  An object of the present invention is to solve such problems, and to provide a cut flower storage packaging box that can reliably prevent the top plate from being lifted.

  The cut flower storage packaging box according to claim 1 of the present invention includes a bottom plate, both side plates connected to the left and right sides of the bottom plate, and an outer front plate portion connected to the front end side of the bottom plate. The inner front plate portion connected to the upper end side of the outer front plate portion, the rear plate connected to the rear end side of the bottom plate, and the top plate connected to the upper end side of the rear plate; A hole formed in the outer front plate portion, comprising a narrow flap continuously provided on the front end side of the top plate, and an insertion piece formed so as to protrude downward in the central portion of the flap. A packaging box for storing cut flowers made of corrugated cardboard so as to maintain the closed state of the top plate by inserting the insertion piece into the hole, and a notch is formed downward in the center in the lateral direction of the hole. In addition, a notch is formed on the upper side of the central portion in the lateral length direction of the hole, and is inserted into the hole. On the insert piece side, a lock piece whose upper end is engaged with the notch portion on the upper side of the hole is formed by cutting at a boundary portion between the narrow flap and the insert piece, and above the lock piece forming portion. Is characterized in that a finger hole is formed.

  As described above, when the top plate is closed, the cut box for storing cut flowers according to the present invention is locked at the position of the cutout portion formed below the hole portion while the insertion piece is inserted into the hole portion. By pushing the piece, the upper end of the lock piece is locked to the notch on the upper side of the hole. As a result, the insertion piece is locked, the top plate is prevented from being lifted, and the top plate is kept closed. When releasing the lock of the insertion piece to open the top plate, the lock piece and the notch are unlocked by pressing the outer front plate above the notch above the hole. Then, the insertion piece can be pulled out from the hole portion by placing the finger on the finger hole and lifting the top plate, and the top plate is opened.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
In the figure, reference numeral 1 denotes a cut flower storage packaging box made of corrugated cardboard, and includes a bottom plate 2, side plates 3, 4 connected to the left and right sides of the bottom plate 2, and the front ends of the side plates 3, 4. Front end flaps 5, 6 connected to the side, upper end flaps 7, 8 connected to the upper end sides of the side plates 3, 4, and an outer front plate part 9 connected to the front end side of the bottom plate 2, The inner front plate portion 10 connected to the upper end side of the outer front plate portion 9, the rear plate 11 connected to the rear end side of the bottom plate 2, and the left and right sides of the rear plate 11. The provided flaps 12 and 13, the top plate 14 provided continuously with the upper end side of the rear plate 11, the narrow flap 15 provided continuously with the front end side of the top plate 14, and the central portion of the flap 15 And an insertion piece 16 formed so as to protrude downward.

  More specifically, the flaps 12 and 13 connected to the left and right sides of the rear plate 11 overlap the inner surfaces of the side plates 3 and 4, and claw pieces 12a and 13a projecting from the upper ends of the flaps 12 and 13 are provided. The side plates 3 and 4 are adapted to engage with holes 17 and 18 formed along the connecting portion between the upper end sides of the side plates 3 and 4 and the upper end flaps 7 and 8. In addition, a vent hole 3a is formed in the vicinity of the upper end of one side plate 3 located on the left side at a position away from the overlapping portion with the flap 12. Further, in the overlapping portion of the other side plate 4 and the flap 13 located on the right side, a vent hole 4a is formed in the vicinity of the upper end of the side plate 4, and a notch portion 13b is formed at the upper end of the flap 13 at the position of the vent hole 4a. Is formed. Further, the upper end flaps 7, 8 are also formed with vent holes 7a, 8a so as to communicate with the vent holes 3a, 4a when the upper end flaps 7, 8 are bent so as to overlap the side plates 3, 4. . Further, the front end flaps 5 and 6 connected to the front end sides of the side plates 3 and 4 are sandwiched between the outer front plate portion 9 and the inner front plate portion 10. A projecting piece 10 a formed at the lower end of the inner front plate portion 10 with the front end flaps 5, 6 sandwiched between the outer front plate portion 9 and the outer front plate portion 9 extends along the connecting portion with the outer front plate portion 9. It is inserted into the hole 2a formed in the above, and a front plate having a double wall structure is formed. Further, in the vicinity of the upper end of the outer front plate portion 9, there is a hole portion 9 a for inserting the insertion piece 16 between the outer front plate portion 9 and the inner front plate portion 10 in a state where the top plate 14 is closed. A substantially semicircular cutout portion 9b is formed downward in the central portion of the hole portion 9a in the lateral length direction, and a shallow depth is formed above the central portion of the hole portion 9a in the lateral length direction. A notch 9c is formed. On the side of the insertion piece 16 to be inserted into the hole 9a, a lock piece 19 whose upper end engages with the notch 9c is formed at the boundary between the narrow flap 15 and the insertion piece 16 by cutting. In addition, a finger hole 20 is formed above the lock piece 19 forming portion.

  In the above configuration, cut flowers (not shown) are housed in the cut flower storage packaging box 1 with the top plate 14 opened, and the top plate 14 is closed. At that time, the insertion piece 16 is inserted into the hole 9a and the lock piece 19 is pushed in at the position of the notch 9b, whereby the upper end of the lock piece 19 is engaged with the notch 9c. Thereby, the insertion piece 16 is locked, the top plate 14 is prevented from being lifted, and the closed state of the top plate 14 is maintained. When the lock of the insertion piece 16 is released to open the top plate 14, the lock piece 19 and the notch 9c are locked by pressing the outer front plate 9 above the notch 9c from the finger hole 20. Is released, and the top plate 14 can be pulled out from the hole 9a by placing the finger on the finger hole 20 and lifting the top plate 14, and the top plate 14 is opened.
