A portion of the bulging portion for preventing deformation that bulges from the upper ends of the left and right side plates is configured to be foldable, and the bent portion is configured to abut against the back surface of the front top plate.

  According to the above configuration, the deformation preventing bulging portion is bent, and the bent portion is in contact with the back surface of the front top plate, so that the contact area is increased, the frictional resistance is increased, and the deformation of the left and right side plates is further prevented. Increases effectiveness.

In the fifth invention, in the first or second invention,
The front top plate is formed with a bulging portion insertion opening into which the deformation preventing bulging portion is inserted.

  According to the above configuration, since the deformation preventing bulging portion fits into the bulging portion insertion opening of the front top plate, the deformation preventing bulging portion is caught by the bulging portion inserting opening. The effect of preventing deformation increases.

In a sixth invention, in the first or second invention,
A bulging portion insertion recess into which the deformation preventing bulging portion is inserted is formed on the back surface of the front top plate.

  According to the above configuration, since the deformation preventing bulging portion fits into the bulging portion inserting concave portion on the back of the front top plate, the deformation preventing bulging portion is caught in the bulging portion inserting concave portion. The effect of preventing the deformation is increased.

  As described above, according to the present invention, in the folding packaging box, the left front flap and the right front flap are formed with the deformation preventing bulging portion, and the left front flap and the right front flap are bent to the back side of the front plate. The bulging part for preventing deformation bulges upward from the upper ends of the left and right side plates and comes into contact with the back of the front top plate.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in a development view before assembling the folding packaging box 1 of the embodiment of the present invention in FIG. 1, the folding packaging box 1 is assembled from, for example, a sheet of corrugated cardboard plate 1a. The foldable packaging box 1 includes a flat bottom plate 2 having a rectangular shape (square or rectangular). A pair of left and right side plates 3 and 4 each having a rectangular shape are continuously formed on the left and right sides of the bottom plate 2. As shown in FIG. 2, the left and right side plates 3 and 4 are bent and raised. On the rear side of the left and right plates 3 and 4, left and right connecting portions 5 and 6 that are hooked to each other are connected. The left and right connecting portions 5 and 6 are formed with flange portions 5a and 6a, respectively, and the rear portions of the left and right side plates 3 and 4 are prevented from spreading by overlapping the flange portions 5a and 6a in the front-rear direction.

  The left side plate 3 is continuous with a left front side flap 7 bent to the right side, and the right side plate 4 is continued with a right front side flap 8 bent to the left side. Further, left and right upper flaps 9 and 10 are connected to the left and right side plates 3 and 4 respectively at the upper ends.

  As shown in FIG. 3, the rear side plate 11 that covers the left and right connecting portions 5 and 6 is erected in a state where the rear left and right connecting portions 5 and 6 are connected. Further, in a state where the left and right front flaps 7 and 8 and the left and right upper flaps 9 and 10 are bent, the front plate 12 is erected and the back side thereof is brought into contact with the left and right front flaps 7 and 8, and is connected to the front plate 12. The front top plate 13 is covered from the upper side of the left front flap 7 and the right front flap 8 and the left and right upper flaps 9 and 10, and the left and right connecting portions 5 and 6 are connected from the rear by the first tip flap 14 at the tip of the front top plate 13. It comes to cover. The front top plate 13 is formed with a product extraction opening 13a.

  In a state where the front top plate 13 is folded, the front top plate 13 is covered from above with a rear top plate 15 continuous with the upper end of the rear plate 11, and the second front end flap 16 at the tip of the rear top plate 15 is attached to the front plate. The insertion tongue piece 18 inserted into the inner opening 17 between the front plate 12 and the front top plate 13 and raised from between the front side plate 12 and the front top plate 13 is interposed between the second tip flap 16 and the rear top plate 15. As shown in FIG. 4, it can be assembled in a rectangular parallelepiped shape.

  As a feature of the present invention, as shown in a partially enlarged view in FIG. 5, when the left front flap 7 and the right front flap 8 are folded on the back side of the front plate 12, A deformation preventing bulge 30 is formed that bulges upward from the upper end and abuts against the back of the front top plate 13. Further, the deformation preventing bulging portion 30 is provided in a range that avoids the left and right upper flaps 9 and 10 when bent. That is, the deformation preventing bulging portion 30 bulges so as to protrude above the height of the left and right side plates 3 and 4 within a range where it does not contact the left and right upper flaps 9 and 10 when bent. The bulging amount is set so that the rear top plate 15 does not bulge. In the present embodiment, the upper end of the deformation preventing bulge 30 is flat.

  Next, a packaging example of the folding packaging box 1 according to the present embodiment will be described. For example, as shown in FIG. 6, the left and right side plates 3, 4, the left and right connecting portions 5, 6 and the rear side plate 11 are raised. Then, the lower tray 20, the intermediate plate 21, and the upper tray 22 are inserted in order from the bottom.

  At this time, for example, the conversion adapter 23 is packed in the lower tray 20, and the mobile phone body 24, the battery pack 25, and other accessories 26 are packed in the upper tray 22.

  Next, the other parts are folded and assembled. When assembling the foldable packaging box 1, it is not necessary to use an adhesive, so that the assembly is extremely easy.

  In the assembled state shown in FIG. 4, since the deformation preventing bulge 30 and the left and right upper flaps 9 and 10 do not overlap, only a part of the front and rear top plates 13 and 15 are raised and the ceiling is raised. The appearance of the board will not deteriorate.

  When the mobile phone body 24 and the battery pack 25 having a large mass are particularly subjected to an impact during transportation, the kinetic energy increases.

  However, in this embodiment, when the deformation preventing bulging portion 30 formed on the left front flap 7 and the right front flap 8 is bent to the back side of the front plate 12 when the left front flap 7 and the right front flap 8 are bent to the left and right sides, Since the top plate 13 bulges upward from the upper ends of the side plates 3 and 4 and comes into contact with the back surface of the front top plate 13, the bulging portion 30 for preventing deformation is transported when the front top plate 13 is pressed by the rear top plate 15 from above. Is in close contact with the rear surface of the front top plate 13.

  For this reason, the left and right side plates 3 and 4 are not deformed by the package even if an impact is applied during transportation due to the frictional force between the deformation preventing bulge 30 and the back surface of the front top plate 13.

  Therefore, according to the foldable packaging box 1 according to the present embodiment, the left and right side plates 3 and 4 can be prevented from being deformed with a simple configuration even if the package moves during transportation.

-Modification 1 of embodiment-
In the above embodiment, the upper end of the deformation preventing bulging portion 30 is flat. However, as shown in FIG. 7, in this modification, deformation is prevented when the corrugated board 1a is cut into the shape of the folding packaging box 1. You may cut | disconnect the contact surface with the front side top plate 13 back surface in the bulging part 130 for a saw in the waveform of a saw. Thus, when the deformation preventing bulge portion 130 comes into contact with the back surface of the front top plate 13, the wave-like portion of the saw is caught, so that the effect of preventing the deformation of the left and right side plates 3 and 4 can be further enhanced. .

-Modification 2 of embodiment-
Moreover, as shown in FIG. 8, you may comprise the part which bulged rather than the upper end of the right-and-left side plates 3 and 4 in the bulging part 230 for deformation prevention so that bending is possible. What is necessary is just to comprise so that this bent part may contact | abut the front side top plate 13 back surface.

  Since the deformation preventing bulging portion 230 is bent, it comes into contact with the back surface of the front top plate 13, so that the contact area is increased, the frictional resistance is increased, and the effect of preventing the deformation of the left and right side plates 3 and 4 is enhanced.

—Modification 3 of Embodiment—
Further, as shown in FIG. 9, a bulging portion insertion opening 330 into which the deformation preventing bulging portion 30 is inserted may be formed in the front top plate 13.

  As a result, the deformation preventing bulging portion 30 is fitted into the bulging portion inserting opening 330 of the front top plate, and the deformation preventing bulging portion 30 is caught by the bulging portion inserting opening 330. The effect of preventing the deformation of the side plates 3 and 4 is enhanced.

  Although not shown in the drawing, a bulging portion insertion recess into which the deformation preventing bulging portion 30 is inserted may be formed without passing through the bulging portion insertion opening 330. Also in this case, since the deformation preventing bulging portion 30 is fitted into the bulging portion inserting concave portion, the effect of preventing the deformation of the left and right side plates 3 and 4 can be enhanced.
