And an inclined side 31d extending toward the other end of the lower side 6c.
The inclined side 31 d is a bending line at the time of overlapping the interlocking joint portion 30B on the outer surface of the base portion 31 while causing the interlocking joint portion 30B to protrude toward the second bottom plate flap 26 side.
The interlocking joint portion 30B is formed so as to overlap with a part of the second bottom plate flap 26 at the time of box making and to be connected by adhesion.

  The fourth bottom plate flap 28 is connected to the fourth side plate portion 5 at the lower side 6 c. The fourth bottom plate flap 28 is formed in a trapezoidal shape that can be bonded in part to the interlocking joint 30A of the first bottom plate flap 25.

Next, a method of folding the blank sheet 1 into a pre-boxed state will be described.
First, the second bottom plate flap 26 is placed on the inner surface of the first side plate portion 2 (that is, the back surface of the surface seen in FIG. 2, the same applies to the following “inner surface”). So as to respectively face the lower side 6c. The third bottom plate flap 27 is bent at the lower side 6 c so as to face the inner surface of the third side plate portion 4 and the fourth bottom plate flap 28 at the inner surface of the fourth side plate portion 5.

The interlocking joint portions 30A and 30B of the first bottom plate flap 25 and the third bottom plate flap 27 are bent at the inclined sides 29d and 31d so as to overlap the outer surfaces of the base portions 29 and 31, respectively.
In this state, an adhesive is applied to the inner surfaces of the interlocking joints 30A and 30B.

  Thereafter, the blank sheet 1 is bent at the side 6 a between the second side plate portion 3 and the third side plate portion 4, and the second side plate portion 3 is superimposed on the inner surface of the third side plate portion 4 and the inner surface of the first side plate portion 2. An adhesive is applied to the outer surface side of the bonding portion 20 in this state. The fourth side plate portion 5 is overlapped on the outer surface of the joint portion 20 and adhered.

As a result, as shown in FIG. 5, the first to fourth side plate portions 2-5 are folded in a flat shape capable of forming the cylinder 6 shown in FIG. Moreover, although illustration of an inside is abbreviate | omitted, in the state in which the 1st-4th bottom plate flap 25-28 was folded inside the cylinder 6, the 1st bottom plate flap 25 and the 4th bottom plate flap 28, the 2nd bottom plate flap 26 And the third bottom plate flap 27 interlocked.
By the above, as shown in FIG. 5, the blank sheet 1 folded flat before box making is completed.

In order to make the blank sheet 1 folded flat before making the box into a three-dimensional packaging box X, the side edges 6a and 6a which are the bending places of the blank sheet 1 in the folded state shown in FIG. Thus, the cylinder 6 is made three-dimensional. When the cylinder 6 is made three-dimensional, the first to fourth bottom plate flaps 25-28 rise along with this operation, and the opening on the lower side 6c side of the cylinder 6 is closed without a gap as shown in FIG.
By the above, as shown in FIG. 1, it becomes the packaging box X which the opening part 7 opened.

An article is suitably stored from the opening 7, and after closing the third top flap 10 and the fourth top flap 11, the second top flap 9 is closed. Under the present circumstances, as shown in FIG. 7, when the reinforcement piece 19 of the 2nd top plate flap 9 is bend | folded inside in the bending part 19c, and the 2nd top plate flap 9 closes the opening part 7, a reinforcement piece 19 is inserted obliquely below the cylinder 6. Then, the first top flap 8 is closed, and the insertion piece 17 is inserted into the insertion slit 16.
As described above, the packaging box X is in the form of a rectangular solid and easy to stack.

  When carrying the packaging box X by hand, the handle 18 shown in FIG. 1 is bent at the connecting end 18b and separated from the first side plate 2 at the separation edge S formed by perforations, and the handle 18 Is pushed upward in the cylinder 6.

As shown in FIG. 4, the length L1 from the connection end 18b to the tip end 18c of the handle 18 is longer than the distance L2 from the upper side 6b of the first side plate 2 to the connection end 18b. Therefore, the tip end edge 18 c of the handle 18 does not coincide with the tip end edge 9 b of the second top plate flap 9, and contacts the vicinity of the bent portion 19 c of the reinforcing piece 19 on the inner surface 9 y of the second top plate flap 9. . As a result, the reinforcing piece 19 is bent diagonally in the direction of the connection end 18 b above the handle portion 18, and the handle portion 18 substantially overlaps the reinforcing piece 19.
As described above, the opening 14 for inserting a hand and the handle 18 capable of being hooked with a finger inclined obliquely upward are formed, and the packaging box X can be easily transported by hand.

Thus, when the opening 7 is closed by the second top plate flap 9, the blank sheet 1 and the packaging box X according to the present invention can be bent in the same direction as the direction in which the reinforcing piece 19 is closed. It can be made to engage with the inner surface of the 1 side plate part 2, and it can fix in the state which it is very hard to remove above. Then, in a state where the first top flap 8 is closed and the second top flap 9 is reliably pressed, the handle portion 18 can be easily set to overlap below the reinforcing piece 19 at any time.
Therefore, the blank sheet 1 and the packaging box X have an effect that the formation of the reinforcing piece 19 is very easy.

  In addition, when the handle portion 18 is overlapped below the reinforcement piece 19 and the hand is held to lift the packaging box X, a load is applied in the direction in which the reinforcement piece 19 is engaged. Therefore, by applying a load to the handle portion 18, the engagement of the reinforcing piece 19 with the first side plate portion 2 can be further strengthened, and the fixing can be made robust.

The load applied to the handle portion 18 is also dispersed with the tip end edge 18 c of the handle portion 18, the bent portion 19 c of the reinforcement piece 19, the tip end edge 19 b of the reinforcement piece 19 and the connecting end edge 18 b of the handle portion 18. be able to. Therefore, it is possible to prevent breakage and the like of the periphery of the opening portion 14 and the handle portion 18 so that the packaging box X can be stably held.
Further, since the auxiliary bending line 18e is formed in the handle portion 18, when the gap between the inside of the cylindrical body 6 and the stored item is small, the handle portion 18 is bent at the auxiliary bending line 18e and the handle portion 18 is inserted from the gap. The effect of being able to

In the present invention, the handle portion 18 includes a plurality of side plate portions other than the second side plate portion 3 facing the first side plate portion 2 in which the handle portion 18 is formed (ie, the third side plate portion 4 and / or the fourth side plate portion 5). Reinforcing pieces 19 may be appropriately formed on the top plate flaps which are formed on the top plate flap and connected to the side plate portions such as the second side plate portion 3, the third side plate portion 4 or the fourth side plate portion 5.
Further, according to the present invention, the handle portion 18 is formed in one first side plate portion 2, and the reinforcing piece 19 is attached to the end portion of the second top plate flap 9 connected to the second side plate portion 3 opposed to the first side plate portion 2. If it forms similarly to the said embodiment, it is applicable also to the packaging box X which has the cylinder 6 of polygons other than a rectangular parallelepiped.

Moreover, although it is preferable that the reinforcement piece 19 reaches near the connection end edge 18b of the handle portion 18, if it is engaged with the inner surface of the first side plate portion 2, the reinforcement piece 19 is engaged slightly higher than the connection end edge 18b. It does not matter. The length of the handle portion 18 is preferably such that the tip end edge 18c reaches near the bent portion 19c of the reinforcing piece 19, but reaches such an intermediate portion between the bent portion 19c of the reinforcement piece 19 and the tip end edge 19b. It may be
Further, the auxiliary bending line 18e formed in the hand portion 18 may not be provided.

Further, as long as the opening 7 of the cylinder 6 can be closed by the second top flap 9 provided with the reinforcing piece 19, another top flap that covers the second top flap 9 is not essential. Moreover, the 1st top plate flap 8 which covers the 2nd top plate flap 9 in which the reinforcement piece 19 was provided may cover a part of 2nd top plate flap 9. FIG.
Further, the form of the one-touch bottom 13 is not limited to the one described in the above embodiment, and other known one-touch bottom forms may be applied as appropriate depending on the dimensions and the like of the cylindrical body 6.
