Therefore, the tongue piece 16 becomes a trigger for the opening operation, and the tape 40 has no trigger. Opening work is easier compared to pinching the corners.

As shown in FIG. 4, the cardboard blank of the packaging box 20 according to the second embodiment is connected to the side plate 21 and the end plate 22 in which each pair is alternately arranged, and to the upper and lower edges of the side plate 21. It has an outer flap 23, an inner flap 24 provided continuously with the upper and lower edges of the end plate 22, and a passage 25 provided continuously with the outer edge of the one side plate.
The boundary between the side plate 21, the end plate 22, the outer flap 23, the inner flap 24, and the passage 25 is a broken line that is thinned by compression processing or the like, and these are mutually rotated around this broken line. It is possible to move.

As shown in the drawing, in detail, in the middle of the opposing side edge portions of both upper outer flaps 23, a concave portion 23a whose outer edge is ¼ arc-shaped is provided.
For this reason, between the recessed part 23a and the front-end | tip of an outer flap has protruded relatively compared with the recessed part 23a, and this part is divided by the zipper part 23b which was cut | disconnected intermittently, and is easy to break. It has become.
As shown in the figure, the convex piece 23c is substantially square, and extends vertically from the front end to the rear end, then bends toward the front end of the outer flap, and then toward the rear end of the outer flap. A curl-like cutout 23d that curls is provided.
Further, a fold line is made from the curl portion at the rear end of the notch 23d toward the outer flap tip side, and the tip end portion 23e of the convex piece 23c defined by the notch 23d is rotatable around the fold line.
On the other hand, as shown in the drawing, the upper inner flap 24 sandwiched between the upper outer flaps 23 has a substantially trapezoidal shape whose width decreases toward the tip.
Further, at the rear end portion, firstly, it extends along the fold line in the middle of the fold line at the boundary between the inner flap 24 and the end plate 22, and then both ends thereof are substantially U-shaped and extend perpendicularly toward the front end of the inner flap. A notch 24a is provided.
Further, a broken line is inserted by connecting the leading ends of the cuts 24a, and a portion partitioned by the cuts 24a can be rotated independently of the inner flap 24 around the broken line, thereby forming an insertion port 27. .

When assembling such a blank into the packaging box 20, first, a fold line at the boundary between the side plate 21 and the end plate 22 is bent, the side plate 21 and the end plate 22 are rotated, and each pair of the side plate 21 and the end plate 22 is rotated.

Further, as shown in the figure, the convex pieces 23c formed on the upper outer flaps 23 are connected to each other to form the tongue piece 26, and at the same time, the tip portions 23e defined by the notches 23d of the convex pieces 23c are also connected to Is formed in a substantially T-shaped insertion portion 26a that protrudes in the lateral direction (in the width direction of the tongue piece 26) and the rear end of which is recessed.

In this state, as shown in FIG. 5, the insertion port 27 of the inner flap 24 is slightly rotated toward the inner side of the packaging box 20 along the broken line, so that the T-shaped difference of the tongue piece 26 of the outer flap 23 is obtained. The insertion portion 26a is bent in the width direction, the protruding portion of the T-shaped insertion portion 26a is inserted into the insertion port 27, and brought into contact with the inner surface of the inner flap 24 to be locked.
By inserting the tongue piece 26 into the insertion port 27 in this way, the outer flap 23 is engaged with the inner flap 24 and temporarily secured.
Therefore, the restoring elasticity of the cardboard material can easily prevent the outer flap 23 from being repelled and opened (rotated in a direction away from each other).
Therefore, the sealing operation | work of the packaging box 20 which bonds the abutting part of the outer flap 23 with the tape 40 shown with a chain line in a figure can be performed smoothly.
In addition, after inserting the tongue piece 26 into the insertion port 27, the insertion port 27 is rotated by the restoring elasticity of the cardboard material, and the tongue piece 26 is sandwiched between the inner flap 24 and the insertion port 27. The insertion part 26a is prevented from coming off.
Further, since the notch 23d at the rear end of the insertion portion 26a is curled, the displacement in the width direction of the insertion portion 26a can be absorbed and the insertion state can be maintained.

On the other hand, when the packaging box 20 is opened by peeling off the tape 40, the zipper portion 23b is broken and the tongue piece 26 is separated from the outer flap 23 as shown in FIG. Pull along the butted portion of the flap 23.
In this way, the tape 40 is attached to the tongue piece 26 and peeled off sequentially from one side of the outer flap 23 to the other side, so that the tongue piece 26 becomes a trigger at the time of opening operation, and the tape 40 has no trigger. Opening work is easier compared to pinching the corners.
Here, since the concave portions 23 a are formed on both sides of the tongue piece 26, it is easy to separate the tongue piece 26 from the outer flap 23 by sliding a finger from the concave portion 23 a into the lower surface of the tongue piece 26.

As shown in FIG. 7, the cardboard blank of the packaging box 30 according to the third embodiment is connected to the pair of side plates 31 and end plates 32 that are alternately arranged, and the upper and lower edges of the side plates 31. It has an outer flap 33, an inner flap 34 connected to the upper and lower edges of the end plate 32, and a joint 35 connected to the outer edge of the one side plate 31.
The boundary between the side plate 31, the end plate 32, the outer flap 33, the inner flap 34, and the passage 35 is a broken line that is thinned by compression processing or the like, and these are mutually rotated around this broken line. It is possible to move.

Specifically, as shown in the drawing, a tongue piece 36 that is partitioned into a substantially oblong oval shape by a notch 32a and a broken line is formed slightly above the center of both end plates 32.
More specifically, the notch 32a defining the tongue piece 36 is substantially U-shaped, and the upper end of the U-shape is curled inward, and a broken line is inserted between the upper ends of the notch. The tongue piece 36 is rotatable independently of the end plate 32 around the broken line.
In addition, the lower end portion of the tongue piece 36 is recessed in a U-shape toward the inside at two locations to form a recess 36a, and a notch 36b that curls in a direction approaching each other from the both recesses 36a to the inside of the tongue piece 36 is provided. It extends.
A portion sandwiched between the recesses 36a at the lower end of the tongue piece 36 protrudes relatively when viewed from the recess 36a, and is partitioned by a curled cut 36b extending from the recess 36a to form an insertion part 36c.
Further, in the middle of the tongue piece 36, a zipper part 36 d that is cut intermittently and runs easily runs across the tongue piece 36.
On the other hand, as shown in the figure, the corners on the front end side of both upper outer flaps 33 are stepped and provided with shoulder portions 33a.

When assembling such a blank into the packaging box 30, first, the folding line at the boundary between the side plate 31 and the end 32 is bent, the side plate 31 and the end plate 32 are rotated, and each pair of the side plate 31 and the end plate 32 is moved. Make it a square tube.
In this state, the folding line at the boundary between the side plate 31 and the passage 35 is bent, the passage 35 is rotated to be along the inner surface of the end plate 32, and is attached to the inner surface of the outer edge of the end plate 32 to form a peripheral wall. .
Next, a fold line at the boundary between the end plate 32 and the upper and lower inner flaps 34 is bent, and the inner flaps 34 are rotated in a direction in which they are close to each other until they are perpendicular to the end plate 32.
Further, the fold line at the boundary between the side plate 31 and the upper and lower outer flaps 33 is bent, and the outer flaps 33 are rotated in the direction in which they are close to each other until they are perpendicular to the side plates 31 and overlap the inner flaps 34.
Here, as shown in FIG. 8, the outer flaps 33 are in abutment state, so that the opening of the square cylindrical peripheral wall is completely closed.
Further, the shoulder portions 33a formed on the upper outer flap 33 are connected to each other to form a notch-shaped insertion port 37 as shown in the figure.

In this state, as shown in FIG. 8, the tongue piece 36 is caused to rotate from the both end plates 32 around the broken line, and overlapped with the upper end portion of the end plate 32.
Next, the tongue piece 36 is folded toward the outer flap 33 side and overlapped with the outer flap 33 by the zipper portion 36 d that crosses the center of the tongue piece 36.
In this state, the insertion portion 36c superimposed on the outer flap 33 of the tongue piece 36 is bent in the vertical direction from the front end to the rear end, and inserted into the insertion port 37 of the outer flap 33, so that the inner surface of the outer flap 33 is To be brought into contact with and locked.
Thus, by inserting the tongue piece 36 into the insertion port 37, the outer flap 33 and the end plate 32 are engaged and temporarily fixed.
Therefore, the restoring elasticity of the cardboard material can easily prevent the outer flap 33 from repelling and opening (rotating in a direction away from each other).
In particular, in this embodiment, since both sides of the outer flap 33 are locked, it is possible to cope with the case where the repulsion of the outer flap 33 is strong.
Therefore, the sealing operation | work of the packaging box 30 which bonds the abutting part of the outer flap 33 with the tape 40 shown with a chain line in a figure can be performed smoothly.
Note that the outer side of the tongue piece 36 in the width direction protrudes relative to the recess 36a, and in a state where the insertion portion 36c is inserted into the insertion port 37, the tongue 36 is overhanging the outer surface of the outer flap 33 as shown in the figure. Because of the contact, the outer flap 33 is sandwiched from above and below by the insertion portion 36c, and the insertion portion 36c is reliably prevented from coming off.
Further, since the notch 32a at the connecting portion of the tongue piece 36 to the end plate 32 and the notch 36b at the rear end of the insertion portion 36c are curled, the tongue piece 36 and the insertion portion 36c absorb the shift in the width direction. In addition, the insertion state can be maintained.
Further, by causing the tongue piece 36 from the end plate 32, a hole 32b is formed in the opposite end plate 32 of the peripheral wall as shown in the figure. By holding this hole 32b, the packaging box 30 can be easily carried. It becomes.

On the other hand, when the tape is peeled off and the packaging box is opened, as shown in FIG. 9, after the zipper portion 36d is broken and the half of the tongue piece 36 is separated from the outer flap 33, the separated tongue piece 36 is removed. It is pinched and pulled along the butted portion of the outer flap 33.
In this way, the tape 40 is attached to the tongue piece 36 and peeled off sequentially from one side of the outer flap 33 to the other side, so that the tongue piece 36 becomes a trigger at the time of opening work, and the tape 40 has no trigger. Opening work is easier compared to pinching the corners.
In this embodiment, since there are two tongue pieces 36, both tongue pieces 36 may be pinched and pulled from both sides of the outer flap 33, or one tongue piece 36 may be pinched to pull the outer flap 33. You may pull from one side to the other.

In each of the above-described embodiments, the tongue pieces 16, 26, and 36 are located on the side portions of the abutting portions of the outer flaps 13, 23, and 33. Therefore, they may be pulled in one direction toward the other side.
For this reason, the tongue pieces 16, 26, 36 are in the middle of the abutting portion, and the work is easier than the case where the tongue pieces 16, 26, 36 must be pulled in two directions toward both sides of the abutting portion of the outer flaps 13, 23, 33.
Further, in each of the above-described embodiments, the tongue pieces 16, 26, and 36 are formed by dividing the inner flap 14, the outer flap 23, and the end plate 32 by the cut 14a, the zipper portion 23b, and the cut 32a, respectively. By processing a blank of a conventional packaging box, it can be used as it is.
