Description

  The present invention relates to a packaging box.

  In a packaging box loaded with a toothbrush or the like that is a stick, a partition plate is glued and fixed inside the packaging box in order to suppress rattling of the toothbrush in the packaging box, and is partitioned by this partition plate. It is common to load a toothbrush into the open space (see, for example, Patent Document 1).

  For example, when the toothbrush is loaded into the packaging box from the direction of the handle part, the tip of the handle part does not collide with the partition plate, and the toothbrush is stored by being partitioned by the partition plate so that the loading operation is easy. The space is generally designed to have a cross-sectional area larger than the cross-sectional area of the handle portion.

  Therefore, in the conventional packaging box, the position of the toothbrush in the packaging box is regulated to some extent by the partition plate. However, since the space in which the toothbrush is accommodated is larger than the cross-sectional area of the handle part, There is a possibility of rattling. For this reason, when the tip of the toothbrush comes into contact with the inner wall of the packaging box due to vibration during transportation, the tip of the toothbrush may be damaged, and it cannot be said that the toothbrush has a sufficient holding and holding effect.

  For example, in Patent Document 2, a partition plate is provided along a diagonal line from the ridge line portion of the packaging box to the opposite ridge line portion inside the packaging box having a square cross-sectional shape, and the toothbrush is stabilized by the spring biasing force of the partition plate. And a fixing technique is disclosed.

  However, in the technique described in Patent Document 2, it is necessary to reduce the cross-sectional area of the space in which the toothbrush is accommodated. Therefore, when the toothbrush is loaded, the handle portion tip easily hits the partition plate, and the partition plate is damaged. There was a problem that it was difficult to do the loading work. In particular, since the partition plate described in Patent Document 2 is arranged along a diagonal line, the distance from the base end portion of the partition plate to the contact portion with the toothbrush is long. Therefore, in order to obtain a sufficient spring urging force, it is necessary to reduce the above-described cross-sectional area. Then, when the toothbrush is loaded, the partition plate is easily damaged or poorly loaded.

  The present invention has been made in consideration of the above points, and an object of the present invention is to provide a packaging box capable of suppressing breakage of a partition plate and poor loading.

The following embodiments show one aspect of the present invention and do not limit the present invention, and can be arbitrarily changed within the scope of the technical idea of the present invention. Moreover, in the following drawings, in order to make each configuration easy to understand, the actual structure is different from the scale and number of each structure.

[First Embodiment]
FIG. 1 is an external perspective view of a packaging box 1 according to the first embodiment. FIG. 2 is a plan view of the packaging box 1. 3 is a cross-sectional view taken along line AA in FIG. FIG. 4 is a plan view of the blank sheet 30 that forms the packaging box 1.

  As shown in FIG. 1, the packaging box 1 is formed in a substantially rectangular parallelepiped shape having an accommodation space 1a inside. The packaging box 1 accommodates the toothbrush TB as a rod-shaped object in the accommodation space 1a. The packaging box 1 includes wide side walls 11, 12 extending in the length direction of the packaging box 1, narrow side walls 13, 14, and ends disposed at the lengthwise ends of the packaging box 1. Walls 15 and 16 are provided.

  The side wall (the other side wall) 11 and the side wall (the one side wall) 12 are arranged to face each other with the accommodation space 1a interposed therebetween. The side wall 13 and the side wall 14 are disposed to face each other with the accommodation space 1a interposed therebetween. The end wall 15 and the end wall 16 are opposed to each other with the accommodation space 1a interposed therebetween.

  In the following, the length direction of the packaging box 1 is defined as the Y direction, the width direction of the side walls 11 and 12 orthogonal to the Y direction is defined as the X direction, and the width direction of the side walls 13 and 14 orthogonal to the Y direction and the X direction. Is appropriately described as the Z direction.

  The side wall 11 has window portions 21 and 22. The windows 21 and 22 are provided with openings formed in the side wall 11 covered with a transparent film or the like. The window portions 21 and 22 are arranged in a state of being biased to the + X side with respect to the center of the side wall 11 in the X direction. The window portion 21 is disposed in the vicinity of the + Y side end portion of the side wall 11 in the Y direction. The window portion 22 is disposed near the center of the side wall 11 in the Y direction. The window parts 21 and 22 make the accommodation space 1a visible through an opening covered with a transparent film.

  As shown in FIG. 2, the toothbrush TB includes a head portion TB1 that is disposed on the front end side and has a flocked portion TB3, and a handle portion TB2 that is disposed on the rear end side of the head portion TB1. In the accommodation space 1a, the head portion TB1 is disposed in the vicinity of the + Y side end portion at a position facing the window portion 21, and the handle portion TB2 is disposed at a position facing the window portion 22 on the −Y side of the head portion TB1. ing. Therefore, in the packaging box 1, at least a part of the head portion TB <b> 1 can be visually recognized through the window portion 21. Further, in the packaging box 1, at least a part of the handle portion TB <b> 2 can be visually recognized through the window portion 22.

  The side wall 12 has a partition plate 27 that is bent from the side wall 12 to partition (partition) the accommodation space 1a. The partition plate 27 holds the handle portion TB2 of the toothbrush TB between the side wall 14 and the partition plate 27.

  As shown in FIG. 3, the side walls 11 to 14 form a cylindrical body 30 </ b> A having a rectangular cross-sectional shape having a length W in the Z direction and a length L in the X direction. For example, when the cross-sectional shape of the handle portion TB2 is an ellipse (see FIG. 6), the maximum length in the major axis direction is H1, and the maximum length in the minor axis direction is H2, the length W is the maximum length H1. It is preferably 100% or more and 120% or less. L / W, which is the ratio of the length L to the length W, is preferably 1.2 or more and 2.0 or less.

  The side wall 12 includes an outer plate 12A bent from the −Z side end of the side wall 14 to the −X side, and an inner plate 12B bent from the −Z side end of the side wall 13 to the + X side. The outer plate 12A is provided so as to be exposed to the outside. The partition plate 27 is bent along a straight line extending in the Y direction at a position away from the side walls 13 and 14 in the X direction in the inner plate 12B and extends toward the intersection of the side wall 11 and the side wall 14. The inner plate 12B is bonded to the rear surface (+ Z side) of the outer plate 12A in a region excluding the partition plate 27. When the partition plate 27 is folded and opened, the accommodation space 1a for accommodating the toothbrush TB is formed as a space having a substantially triangular cross section surrounded by the side wall 12, the side wall 14, and the partition plate 27.

As shown in FIGS. 2 and 4, the partition plate 27 has the same width portion 27 </ b> A formed with a constant length in the X direction, and the length in the X direction as the separation plate 27 moves away from the same width portion 27 </ b> A toward the + Y side. Has a reduced width portion 27B that gradually becomes shorter. FIG. 3 shows a cross-sectional view taken along a plane passing through the same width portion 27 </ b> A of the partition plate 27. The partition plate 27 is disposed at a position shifted from the window portions 21 and 22 in the Y direction. The partition plate 27 is disposed on the −Y side from the window portion 22. It is preferable that the partition plate 27 is located at a position 10 mm or more away from the −Y side end of the window portion 21. It is preferable that the partition plate 27 is disposed within a range of 30 mm on the + Y side or the −Y side from the center in the Y direction of the packaging box 1.
When the partition plate 27 is located at a position 10 mm or more away from the −Y side end of the window portion 21, the partition plate 27 is not visible when the head portion TB <b> 1 and the flocked portion TB <b> 3 are visually recognized from the window portion 21. It will not interfere with the visual recognition of the store, and will improve the appearance in scenes such as store displays. On the other hand, when the partition plate 27 is arranged within 30 mm on the + Y side or the −Y side from the center in the Y direction of the packaging box 1, the partition plate 27 is placed on the side surface near the center portion in the length direction of the handle portion TB2. Since the contact is possible, the toothbrush can be stably fixed as compared with the case where the handle portion TB2 is in contact with the side surface near the tip portion.

  The partition plate 27 is disposed in an unconstrained state with the distal end 28 being separated from the side wall 11 and the side wall 14. The partition plate 27 has a distal end 28 that is movable around a base end 29 at a position bent in the inner plate 12B.

  The maximum length (width of the same width portion 27A) L11 between the base end 29 and the front end 28 of the partition plate 27 is longer than the distance L12 between the base end 29 and the side wall 14 (L11> L12). The distance L12 between the base end 29 and the side wall 14 is ½ or less of the length L in the X direction of the side wall 12, and is not less than the maximum length H2 in the minor axis direction of the handle portion TB2. The maximum length L11 is shorter than the distance L13 from the base end 29 to the intersection of the side wall 11 and the side wall 14 (L11 <L13).

  Returning to FIG. 4, the blank sheet 30 is formed of paperboard. Cardboard, coated cardboard, or the like can be used as the paperboard material.

  The blank sheet 30 is formed by punching card paper, for example. As shown in FIG. 4, the blank sheet 30 has an outer plate 12 </ b> A, side walls 14, 11, 13 and an inner plate 12 </ b> B arranged in order from the left side via folding lines 31 to 34. The inner plate 12B is bonded to the back side of the outer plate 12A when the blank sheet 30 is assembled and the packaging box 1 is formed.

  In FIG. 4, with respect to the blank sheet 30, the side wall 11 developed in a direction perpendicular to the y direction is a direction corresponding to the Y direction that is the length direction of the packaging box 1 (the vertical direction in FIG. 4). The direction in which -14 is arranged (the left-right direction in FIG. 4) is referred to as the x direction, and the direction orthogonal to the x direction and the y direction (the direction orthogonal to the paper surface in FIG. 4) is appropriately described as the z direction.

  The blank sheet 30 has inner flaps 17A and 17B extending from both ends in the length direction (y direction) of the side wall 13 via folding lines 35A and 35B, respectively. The blank sheet 30 has inner flaps 18A and 18B that extend from both ends of the side wall 14 in the y direction via folding lines 36A and 36B, respectively.

  The blank sheet 30 has outer flaps 19A and 19B that extend from both ends of the side wall 11 in the y direction via folding lines 37A and 37B, respectively. An insertion portion 20A extends to the + y side via a fold line 38A at the tip of the outer flap 19A. An insertion portion 20B extends to the −y side via a fold line 38B at the tip of the outer flap 19B. The side wall 11 has an opening 21 a that becomes the window 21 and an opening 22 a that becomes the window 22.

  Since the inner plate 12B is bonded to the back side of the outer plate 12A when the packaging box 1 is formed, the inner plate 12B is formed to have a width smaller than the width of the side wall 12 in the X direction. On the end wall 16 side of the inner plate 12B from the center in the y direction, recesses 23 and 24 are formed with an interval in the y direction. The recesses 23 and 24 open to the edge 25 on the side opposite to the folding line 34 in the width direction in the inner plate 12B. The maximum recess lengths of the recesses 23 and 24 from the edge 25 are the same. The inner plate 12B has a fold line 38 that connects the most depressed positions of the recesses 23 and 24. The fold line 38 extends in the y direction. A partition plate 27 extends to the end 25 side (−x side) from the fold line 38. The fold line 38 is the base end 29 of the folded partition plate 27.

  The packaging box 1 is assembled by first folding the folding lines 31 to 34 in the blank sheet 30 and removing the inner plate 12B excluding the partition plate 27 from the back side of the outer plate 12A (packaging) with an adhesive such as hot melt. A cylindrical body 30A shown in FIG. 5 is formed by adhering to the surface facing the accommodation space 1a when assembled as the work box 1.

  FIG. 5 is a schematic cross-sectional view of the cylindrical body 30A in a state where the outer plate 12A and the inner plate 12B are bonded, cut along a plane parallel to the xz plane passing through the partition plate 27 (the same width portion 27A). . Immediately after starting the opening of the cylindrical body 30A in a state where the outer plate 12A and the inner plate 12B are bonded, as shown in FIG. 5 (a), the intersection between the side wall 11 and the side wall 13, and the outer plate It will be in the state inclined so that the intersection of 12A and the side wall 14 may become an obtuse angle.

  Next, as shown in FIG. 5B, the cylindrical body 30A so that the intersecting portion between the side wall 11 and the side wall 13 intersecting at an obtuse angle and the intersecting portion between the outer plate 12A and the side wall 14 approach each other at a right angle. Advance the opening of Here, as shown in FIG. 3, the maximum length (width of the same width portion 27A) L11 of the partition plate 27 is longer than the distance L12 between the base end 29 and the side wall 14, and thus the cross section of the cylindrical body 30A. The tip 28 of the partition plate 27 comes into contact with the inner surface of the side wall 14 before the shape becomes a rectangle having a length L in the X direction and a length W in the Z direction (see FIG. 3).

  Further, when the cylindrical body 30A is opened, the tip 28 slides along the inner surface of the side wall 14 while the contact position with the inner surface of the side wall 14 moves to the + Z side. That is, the partition plate 27 is opened with the opening of the cylindrical body 30A. FIG. 5C shows a state where the cross-sectional shape of the cylindrical body 30A is rectangular.

  When the boxing is released in a state where the cross-sectional shape of the cylindrical body 30A is rectangular, the cylindrical body 30A is caused by the reaction force (spring back) so that the cylindrical body 30A intersects the side wall 11 and the side wall 13 and the outer plate 12A and the side wall. 14 tries to return to an inclined state so that the intersection with 14 becomes an obtuse angle. Therefore, as shown in FIG. 5D, the cross-sectional shape of the cylindrical body 30A is such that the cross-sectional shape of the cylindrical body 30A becomes rectangular when the raised state is returned by the reaction force (spring back). So that the cross section between the side wall 11 and the side wall 13 and the cross section between the outer plate 12A and the side wall 14 are inclined so as to be at an acute angle so that the cross section is further deformed from the rectangular state. Is released.

  Thereby, as shown in FIG. 5E, the cylindrical body 30A is formed into a rectangular parallelepiped shape with a rectangular cross-sectional shape. At this time, the partition plate 27 extends from the base end 29 in the direction of the intersection with the side wall 11 and the side wall 14, and the distal end 28 is separated from the side wall 11 and the side wall 14.

  Thereafter, the toothbrush TB is loaded from the + Y side opening in the cylindrical body 30 </ b> A into the accommodation space 1 a surrounded by the side wall 12, the side wall 14, and the partition plate 27. The loading of the toothbrush TB into the accommodation space 1a is inserted from the handle portion TB2.

  FIG. 6 is a cross-sectional view showing a state in which the handle portion TB2 is inserted into the cylindrical body 30A in the state shown in FIG. As shown in FIG. 6, the cross-sectional shape of the handle portion TB2 is an oval as an example. Further, as shown in FIG. 2, the distal end portion of the handle portion TB2 has a circular arc shape in plan view that tapers toward the -Y side. The handle portion TB2 is inserted in a state of being close to the side wall 14. When viewed from the −Y side, the partition plate 27 is disposed at a position overlapping the handle portion TB2 as shown by a two-dot chain line in FIG. 6 before the handle portion TB2 is inserted.

  Here, as shown in FIG. 2, the partition plate 27 has a distal end 28 that overlaps the base end 29 at a position Y1 closest to the + Y side, and a position Z1 in the Z direction of the distal end 28 shown in FIG. At the same position as the base end 29. Therefore, when the tip of the handle portion TB2 inserted into the accommodation space 1a reaches the position Y1, the partition plate 27 does not come into contact with the handle portion TB2, as can be seen from FIGS.

  On the other hand, the position Z2 in the Z direction of the tip 28 when the partition plate 27 in the raised state first comes into contact with the side surface of the handle portion TB2 is the reduced width portion 27B of the partition plate 27 as shown in FIG. Is determined by the position 28a of the tip 28 at the position Y2 in the Y direction. FIG. 7 is an enlarged partial plan view of the vicinity of the position Y2 in the Y direction in the reduced width portion 27B when the side surface of the handle portion TB2 inserted into the cylindrical body 30A first comes into contact with the partition plate 27. FIG. 8 is a cross-sectional view taken along a position Y3 on the −Y side of the Y-direction position Y2 when the side surface of the handle portion TB2 inserted into the cylindrical body 30A first comes into contact with the partition plate 27.

  As shown in FIG. 7, since the handle portion TB2 is tapered at the position Y3 than the position Y2, the cross-sectional shape at the position Y3 is smaller than the cross-sectional shape at the position Y2. Therefore, as shown in FIG. 8, the handle portion TB2 is inserted into the accommodation space 1a between the partition plate 27 and the side wall 14 without contacting the partition plate 27 at the position Y3 on the −Y side of the position Y2. It is a state that has been. Therefore, even if the handle portion TB2 inserted into the accommodation space 1a is further inserted on the −Y side from the position Y2 where it first contacts the partition plate 27, the partition plate 27 is not damaged.

  By inserting the handle portion TB2 further to the −Y side from the position Y2, the contact position of the partition plate 27 with the side surface of the handle portion TB2 changes, and the entire toothbrush TB is inserted into the accommodation space 1a of the cylindrical body 30A. When this is done, as shown in FIG. 6, the handle portion TB2 is brought into contact with the side surface of the handle portion TB2 while being raised (moved) from the initial position indicated by the two-dot chain line, and between the side wall 14 and the handle portion TB2. Hold.

  In the partition plate 27 of the present embodiment, since the base end 29 is disposed at a position separated from the side wall 13 and the side wall 14, the base end 29 is disposed at the intersection of the side wall 12 and the side wall 13, and the partition plate is cylindrical. Compared to the case where the body 30A is disposed along the diagonal line, the distance from the base end 29 to the position where the body 30A contacts the side surface of the handle portion TB2 inserted into the accommodation space 1a is short. Accordingly, the partition plate 27 comes into contact with the side surface of the handle portion TB2 inserted into the accommodation space 1a from the initial position in the Z direction of the tip 28 of the same width portion 27A before the handle portion TB2 is inserted into the accommodation space 1a. When the movement distance in the Z direction to the position in the Z direction of the tip 28 of the same width portion 27A is the same, the base end 29 is disposed at the intersection of the side wall 12 and the side wall 13, and the partition plate is a diagonal line of the cylindrical body 30A. Compared with the case where it arrange | positions along, the rotation angle of the partition plate 27 centering on the base end 29 becomes large.

  That is, the partition plate 27 in which the base end 29 is disposed at a position separated from the side wall 13 and the side wall 14 has a larger amount of elastic deformation than the partition plate disposed along the diagonal line of the cylindrical body 30A. Therefore, the partition plate 27 of the present embodiment can hold the handle portion TB2 with the side wall 14 with a larger elastic restoring force than the partition plate arranged along the diagonal line of the cylindrical body 30A. In addition, compared with the case where the partition plate is arranged along the diagonal line of the cylindrical body 30A, the distance from the base end 29 to the position where the partition plate comes into contact with the side surface of the handle portion TB2 inserted into the accommodation space 1a is larger. Since it is short, the partition plate 27 itself is not easily deformed when the handle portion TB2 is inserted into the accommodating space 1a, and the handle portion TB2 can be held between the side wall 14 with a stronger force.

  Here, the ratio of the maximum length L11 between the proximal end 29 and the distal end 28 of the partition plate 27 to the distance L13 from the proximal end 29 to the intersection of the sidewall 11 and the sidewall 14 is 75% or more and 95% or less. It is preferable that When the ratio of the length L11 to the distance L13 is less than 75%, since the length L11 of the partition plate 27 is short, it becomes difficult to sufficiently partition the accommodation space 1a, and the toothbrush TB is loaded into the accommodation space 1a. There is a possibility that the handle portion TB2 cannot be sufficiently held. When the ratio of the length L11 to the distance L13 exceeds 95%, the length L11 of the partition plate 27 is long, so that the side plate 11 is easily contacted, and the movable range of the tip 28 of the partition plate 27 is narrowed. Therefore, from the viewpoint of sufficiently holding the handle portion TB2 and securing the movable range of the tip 28 of the partition plate 27, the ratio of the maximum length L11 to the distance L13 is 75% or more and 95% or less. preferable.

When the entire toothbrush TB is inserted into the accommodation space 1a of the cylindrical body 30A, the inner flap 17A and the inner flap 18A are bent to join the outer flap 19A from the outside, and the insertion portion 20A is formed on the side wall 12 (inner plate 12B). The end wall 15 is formed by being inserted in from the + y side. Further, the inner flap 17B and the inner flap 18B are bent to join the outer flap 19B from the outside, and the insertion portion 20B is inserted into the side wall 12 (inner plate 12B) from the −y side, whereby the end wall 16 is formed. The
Thereby, the packaging box 1 in which the toothbrush TB is loaded in the accommodation space 1a is formed.

  As described above, in the packaging box 1 of the present embodiment, the distal end 28 of the partition plate 27 is not constrained, and the partition plate 27 itself can move around the base end 29. Even when the toothbrush TB is reduced to reduce rattling, the partition plate 27 moves even when the handle portion TB2 of the toothbrush TB abuts against the partition plate 27 during loading. The occurrence of breakage can be suppressed. Furthermore, in the packaging box 1 of the present embodiment, the partition plate 27 that is bent from the side wall 12 and extends toward the + X side end of the side wall 11 is centered on the base end 29 that is spaced apart from the side wall 13 and the side wall 14. Since the distal end 28 is movably provided, the handle portion between the side wall 14 and the base end 29 can be moved with a large elastic restoring force as compared with the case where the base end 29 is disposed at the intersection of the side wall 12 and the side wall 13. TB2 can be held. In particular, in the packaging box 1 of the present embodiment, since the position of the base end 29 is arranged on the + X side with respect to the X direction center of the side wall 12, The distance from the base end 29 to the contact position can be shortened, and the handle portion TB2 can be held between the side wall 14 with a larger elastic restoring force.

  Moreover, in the packaging box 1 of this embodiment, since the length L11 of the partition plate 27 is longer than the distance L12 from the base end 29 to the side wall 14, the cross-sectional shape of the cylindrical body 30A is formed into a rectangle. Thus, the partition plate 27 can be opened. Therefore, in the packaging box 1 of this embodiment, it is not necessary to separately provide a process for opening the partition plate 27, which can contribute to improvement in manufacturing efficiency.

[Second Embodiment]
Next, 2nd Embodiment of the packaging box 1 is described with reference to FIG.9 and FIG.10.
In these drawings, the same components as those of the first embodiment shown in FIGS. 1 to 8 are denoted by the same reference numerals, and the description thereof is omitted.
The difference between the second embodiment and the first embodiment is a partition plate 27.

FIG. 9 is a cross-sectional view of the packaging box 1 according to the second embodiment, cut along a plane passing through the partition plate 27 and parallel to the XZ plane.
As shown in FIG. 9, the partition plate 27 of the second embodiment has a fold ruled portion 27C extending in the Y direction. The crease part 27C is mountain-folded so that the -X side is convex after opening.

  The sum of the length L1 from the base end 29 to the crease 27C and the length L2 from the crease 27C to the tip 28 of the partition plate 27 is from the base 29 to the intersection of the side wall 11 and the side wall 14. The distance L13 (see FIG. 3) is preferably 90% or more and 100% or less. Moreover, it is preferable that the ratio (value represented by L1 / L2) of the length L1 with respect to the length L2 is 0.67 or more and 1.5 or less.

  When the value represented by L1 / L2 is less than 0.67 or exceeds 1.5, the folding ruled portion 27C is not bent correctly when the tubular body 30A described later is opened (for example, a valley shape in which the −X side is concave). ). When the sum of the length L1 and the length L2 is less than 90% of the distance L13, the amount of folding at the crease portion 27C is reduced, and the handle portion TB2 that is caused by the fold at the crease portion 27C is accommodated. There is a possibility that the space 1a cannot be sufficiently expanded. When the sum of the length L1 and the length L2 exceeds 100% of the distance L13, when the cylindrical body 30A described later is opened (especially when the cross-sectional shape of the cylindrical body 30A is rectangular) ), The above-described folding ruled portion 27C is likely to be broken.

  Subsequently, a procedure for forming the cylindrical body 30A in a state where the outer plate 12A and the inner plate 12B are bonded into a rectangular cross-sectional shape will be described with reference to FIG. In FIG. 10, the sum of the length L1 and the length L2 is the same as the distance L13 from the base end 29 to the intersection of the side wall 11 and the side wall 14 (the sum of the length L1 and the length L2 is the distance The case of 100% of L13 will be described.

  Immediately after starting the opening of the cylindrical body 30A in a state where the outer plate 12A and the inner plate 12B are bonded, as shown in FIG. 10 (a), the intersection between the side wall 11 and the side wall 13, and the outer plate It will be in the state inclined so that the intersection of 12A and the side wall 14 may become an obtuse angle.

  Next, as shown in FIG. 10B, the cylindrical body 30A so that the intersecting portion of the side wall 11 and the side wall 13 intersecting at an obtuse angle and the intersecting portion of the outer plate 12A and the side wall 14 approach a right angle. Advance the opening of Thereby, the front end 28 of the partition plate 27 comes into contact with the inner surface of the side wall 14.

  Further, when the cylindrical body 30A is opened, the tip 28 slides along the inner surface of the side wall 14 while the contact position with the inner surface of the side wall 14 moves to the + Z side. FIG. 10C shows a state where the cross-sectional shape of the cylindrical body 30A is rectangular. At this time, the front end 28 of the partition plate 27 is in contact with the intersection of the side wall 11 and the side wall 14.

  Subsequently, in order to avoid an excessive return of the opening due to the springback, as shown in FIG. 10D, the side wall 11 and the side wall are so formed that the cross-sectional shape of the cylindrical body 30A is further deformed from the rectangular state. The box opening is canceled after the box opening is advanced to a state where the crossing section with 13 and the section between the outer plate 12A and the side wall 14 are inclined so as to have an acute angle. At this time, the partition plate 27 is bent into a mountain fold where the −X side is convex in the crease portion 27 </ b> C when the tip 28 is pressed against the intersection of the side wall 11 and the side wall 14.

  By releasing the boxing, the cylindrical body 30A is formed into a rectangular parallelepiped shape having a rectangular cross section as shown in FIG. At this time, the partition plate 27 bends at the crease portion 27C, extends from the crease portion 27C toward the intersection with the side wall 11 and the side wall 14, and the tip 28 is in a state of being separated from the side wall 11 and the side wall 14. .

  Thereafter, the handle portion TB2 is inserted into the accommodating space 1a between the side wall 14 and the partition plate 27, but the partition plate 27 is bent into a mountain fold having a convex side on the −X side at the crease portion 27C. As shown in the embodiment, the accommodation space 1a between the side wall 14 and the partition plate 27 is expanded as compared with the case where the partition plate 27 is a flat plate, and the insertability of the handle portion TB2 is improved.

After the toothbrush TB is loaded into the accommodation space 1a, the end wall 15 and the end wall 16 are further formed.
Thereby, the packaging box 1 in which the toothbrush TB is loaded in the accommodation space 1a is formed.

  In the packaging box 1 of the present embodiment, in addition to obtaining the same functions and effects as those of the first embodiment, the folding ruler portion 27C is bent and the accommodation space 1a is expanded, so that the handle portion TB2 can be inserted. improves.

  As described above, the preferred embodiments according to the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the examples. Various shapes, combinations, and the like of the constituent members shown in the above-described examples are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

  For example, in the above-described embodiment, the toothbrush TB is exemplified as the shaft-shaped object, but the present invention is not limited to this configuration, and other shaft-shaped objects can be applied.

  Moreover, in the said 2nd Embodiment, although the structure which provides the one folding ruled part 27C was illustrated, it is not limited to this structure. For example, a configuration in which a plurality of creases 27C are provided at intervals in a direction orthogonal to the length direction of the crease part 27C may be employed. By providing a plurality of the crease portions 27C, it is easy to avoid the problem that any one of the crease portions 27C is always folded at the time of opening and the portions other than the crease portions 27C are accidentally broken. For this reason, it is difficult to cause poor opening.
