Description

The present invention relates to a packaging box used for packaging pharmaceuticals and various other articles, and in particular, the box has a buffering function inside and is suitable for individually packaging vials and other bottles containing medicines such as liquid medicines and tablets. Regarding packaging boxes with a cushioning function that are ideal for.

This type of packaging box with a buffer function is proposed in Patent Document 1. Patent Document 1 relates to a packaging box with a cushioning function that is integrally provided with a buffer partition inside and protects contents such as bottles. , comprising a substantially rectangular and vertically elongated outer cylindrical body S1, and a cylindrical housing part S2 arranged to face each other with a predetermined gap as a buffer partition inside the outer cylindrical body S1, and an inner side of the outer cylindrical body S1. The accommodation portion S2 is designed to buffer and hold an object W that is vulnerable to impact, such as a glass bottle.

The packaging box 1 is made up of a single box-forming piece 12 punched out of a blank sheet such as cardboard. As shown in FIG. 2 of Patent Document 1, the box-forming piece 12 includes a first side plate 14, a front plate 16, a second side plate 18, a back plate 20, and a third side plate 62, which constitute the outer cylindrical body. are connected in parallel, and the front partition plate 64, the second partition part 88, the back partition plate 68, and the first partition part 108, which constitute the accommodating part S2, are connected in parallel from the edge of the back plate 20. In this box-forming piece 12, as shown in FIGS. 3 to 7 of Patent Document 1, each part of the outer cylindrical body S1 is sequentially bent and glued from each part on the accommodating part S2 side. In this case, in particular, the first glued part 84 extending from the front partition plate 64 and the back partition plate 68 is glued to the back surface of the second side plate 18 and extends from one end of the first partition part 108. A glued piece 96 is glued to the back side of the back plate 20, and a third glued part 112 extending from the other end of the first partition part 108 is close to the first side plate 14 of the front partition plate 64. The parts are glued.

By bending and gluing the box-forming piece 12 in this manner, the box-forming piece 12 is folded into a flat shape so that it can be assembled into a box. That is, the outer cylindrical body S1 of this box-forming piece 12 is raised with one touch, and the housing portion S2 is raised inside the outer cylindrical body S1. Moreover, by this raising, the stored object support part 110 is arranged at the lower opening of the storage part S2 so as to cross between the front partition plate 64 and the rear partition plate 68.

In this way, the lower opening of the outer cylindrical body S1 is closed by the lower lid piece 44, and in this state, as shown in FIG. Can be put in. The stored item W has its own sides held by the front partition plate 64, the second partition part 88, the rear partition plate 68, and the first partition part 108, and its own bottom surface supported by the stored item support part 110. Ru. Then, the upper opening of the outer cylindrical body S1 is closed by the upper lid piece 52.

By packaging the contents W in this packaging box, even if an impact is applied from any direction on the outer peripheral surface of the outer cylindrical body S1, the accommodating part S2 will not come into contact with the outer cylindrical body S1, and the accommodating part S2 itself will be flexible. Since the shock is absorbed by the structure, a large shock is not transmitted to the stored object W in the storage section S2. In addition, since the stored items W in the storage section S2 are supported from below by the stored item holding section 110, the packaging box 10 is placed with the lower lid piece 44 side facing down in normal handling. A sufficient buffering effect can be obtained.

Therefore, a stored object such as a glass bottle is supported by this linear stored object support section 110. In order to support relatively heavy stored items such as glass bottles with such a linear stored item support part 110, this stored item support part 110 needs to have a certain degree of strength, and in order to ensure this strength, , a certain length (height) is required in the vertical direction (height direction) of this rectangular stored object support portion 110. For this reason, it is difficult to compress the height of this packaging box. In other words, in the case of this box, if you try to compress (shorten) the height of the content support part 110, the strength of the content support part 110 will decrease, causing it to bend when assembling the box, or to prevent the content from becoming a shock absorber.

Ru. As a result, the two inner side plate-shaped portions 25P and 26P are overlapped, and portions 25A and 26A are adhesively fixed. Next, the folding line L13 between the first and second extension plate-shaped parts 21P and 22P is folded into a mountain fold, and the second, third, and fourth extension plate-shaped parts 22P, 23P, and 24P form the first extension plate. The shape portion 21P is folded into the inner surface of the back plate shape portion 11P, the outer surface of the fixing portion shape portion 242P of the fourth extension plate shape portion 24P, and the inner surface of the adhesive piece shape portion 15P (first extension plate shape portion 21P). The space between them is fixed with adhesive. As a result, the fourth extension plate shaped part 24P and the adhesive piece shaped part 15P are connected, and the second, third, and fourth extension plates are placed on the inner surfaces of the first extension plate shaped part 21P and the back plate shaped part 11P. The shaped parts 22P, 23P, and 24P are overlapped.
Furthermore, the first extension plate-shaped part 21P, the back plate-shaped part 11P, in which the second, third, and fourth extension plate-shaped parts 22P, 23P, and 24P are superimposed, are the back plate-shaped part 11P, and the right side plate-shaped part. The folding line L1 between 12P is folded into a mountain, and folded and overlapped on the inner surfaces of the right side plate-shaped part 12P and the front plate-shaped part 13P, and the outer surface of the fixing part-shaped part 232P of the third extension plate-shaped part 23P, the right side. The inner surfaces of the face plate shaped portion 12P are adhesively fixed via glue. As a result, the inner extension plate-shaped portions 21P-24P are completely folded onto the inner surfaces of the four side plate-shaped portions 11P-14P. Then, the folding line L3 between the front plate-shaped portion 13P and the left side plate-shaped portion 14P is folded into a mountain, and the left side plate-shaped portion 14P is folded onto the adhesive piece-shaped portion 15P. The outer surface of the portion 15P is adhesively fixed via glue. As a result, the four side-shaped portions 11P-14P are connected. In this way, the four side plate-shaped parts 11P-14P can be raised into a box shape (box main body 1), and the inner extension plate-shaped parts 21P-24P can be raised into a cylindrical shape, respectively, and the two inner side plate-shaped parts 25P, 26P can be raised. is folded into a substantially V-shape so that it can be separated.

From the blank sheet P1 which has been folded in this way, the folding line L3 between the front plate shaped part 13P and the left side plate shaped part 14P, and the folding line L1 between the back plate shaped part 11P and the right side plate shaped part 12P are pressed. With one touch, the four side plate-shaped parts 11P-14P are raised into a box shape, the inner extension plate-shaped parts 21P-24P are raised into a cylindrical shape, and the two inner side plate-shaped parts 25P and 26P are raised into a substantially V-shape. The box body 1 is separated and assembled, and the partition 2 is integrally assembled in the box body 1 from the vertical middle to the bottom lid side.

In this case, the four side plate-shaped parts 11P-14P are bent at about 90 degrees between the respective side plate-shaped parts 11P, 12P, 13P, and 14P by mountain-folding the respective folding lines L1, L2, and L3, The box body 1 is assembled into a box shape with a substantially rectangular cross section. In the inner extension plate-shaped parts 21P-24P, the adhesive piece-shaped part 15P is bent at about 90 degrees with respect to the back plate-shaped part 11P by mountain-folding the folding line L4 between the two, and the second extension plate-shaped part 22P is formed. is bent at about 90 degrees by mountain-folding the folding line L13 between them with respect to the first extension plate-shaped part 21P, and the third extension plate-shaped part 23P is bent with respect to the second extension plate-shaped part 22P. The folding line L14 between the two is folded into a mountain and bent at approximately 90 degrees, and the fourth extension plate-shaped portion 24P is folded into a mountain at the folding line L15 between the two with respect to the third extension plate-shaped portion 23P. Can be bent at 90°. At the same time, the portion between the protruding part shape part 231P and the fixing part shape part 232P of the third extension plate shape part 23P is bent at about 90 degrees by mountain-folding the folding line 231a, and the fourth extension plate shape part 24P and the fixing portion shape portion 242P are bent at about 90° by making a mountain fold along the folding line 242a. The holding portion shape portion 243P extending from the fourth extension plate shape portion 24P is bent at an angle obtuse than 90° with respect to the extension plate shape portion 24P by mountain-folding the folding line 243a. In this way, the inner extension plate-shaped parts 21P-24P are assembled into a cylindrical shape with a square cross section as part of the partition 2 within the box body 1.

At the same time, the two inner side plate-shaped parts 25P and 26P are bent at an obtuse angle than 90° by mountain-folding the folding lines L18 and L19 with respect to the third and fourth extension plate-shaped parts 23P and 24P. , a part 26A of the inner side plate-shaped part 26P on the fourth extension plate-shaped part 24P side with respect to the inner side plate-shaped part 25P on the third extension plate-shaped part 23P side is two inner side plate-shaped parts 25P, The folding line L20 between 26P is bent to about 180 degrees, and the inner side plate shape part 25P on the side of the third extension plate shape part 23P and the inner side face plate shape on the side of the fourth extension plate shape part 24P. A portion 26A of the portion 26P and the remaining portion 26B of the inner side plate-shaped portion 26P on the fourth extension plate-shaped portion 24P side are bent at an angle more acute than 90° by making a valley fold along the folding line 262 between them. Thus, the two inner side plate-shaped parts 25P, 26P are assembled into a substantially V-shape below the inner extension plates 21-24.

Then, the bottom opening 10D is closed by each part of the bottom lid-shaped part 17P, and the top opening 10U is closed by each part of the canopy-shaped part 16P, so that the entire box B1 is assembled into a substantially rectangular parallelepiped-shaped box B1.

Along with the process of assembling the box B1, vials are housed and packaged in the box B1.

In this way, in this box B1, the partition 2 is formed in the box body 1 from the vertical middle to the bottom lid side, and supports the bottom part along with the periphery (periphery) of the vial in the box body 1, and suspends the vial in the air. It is designed to be held elastically in a closed position.

FIG. 6 shows how the vials packaged in the box B1 are accommodated in the box B1.
As shown in FIG. 6, in this box B1, the vial is supported by each side of the inner extension plate 21-24, which has a cylindrical peripheral surface, and the inner extension plate 21-24 and the four sides of the box body 1. It is elastically held with buffer spaces 210-240 interposed between it and the face plates 11-14. In addition, the vial is supported by the upper part of two inner side plates 25 and 26, each having a substantially V-shaped bottom, and is elastically supported through a buffer space 170 between the bottom of the vial and the bottom lid 17 of the box B1. is maintained.

In this way, in this box B1, as shown in FIG. 6(a), the vial is housed in the cylindrical inner extension plate 21-24 in the box B1, and the circumferential surface of the vial is buffered in the box B1. It is supported in the cylindrical inner extension plates 21-24 through the spaces 210-240 in contact with the extension plates 22, 23, 24 and the holding part 243, and even if a strong external force is applied from the outer circumferential direction of the box B1, The inner extension plates 21-24 that receive the external force are bent within the buffer spaces 210-240, thereby absorbing even a strong impact. This protects the vial from strong external forces in the circumferential direction. Further, in this case, as shown in FIG. 6(b), the vial is placed on the upper part of the two inner side plates 25, 26 assembled in a substantially V shape, and the inner side plates 25, 26 form a substantially V shape. The vial is vertically expandable and retractable with its tip (lower end) in contact with the inner surface of the bottom lid 17 of the box B1, and the vial is supported on the two approximately V-shaped inner side plates 25 and 26, and the vial is Even if a strong external force is applied to B1 in the vertical direction, the inner side plates 25 and 26 expand and contract between the bottom of the vial and the bottom cover 17 of the box B1, so that even the strong impact is absorbed. This protects the vial from strong external forces in the vertical direction. Therefore, even if an impact is applied to the box B1, the vials in the box B1 will not be damaged and will be reliably protected.

In addition, in this packaging box B1, a break line C1 consisting of a trapezoidal perforation line is formed downward from the fold line L7 on the upper part of the front plate 13, and when opening the box B1, this break line C1 is formed downward from the fold line L7. The canopy 16 can be opened by pressing and breaking the opening T1 surrounded by C1. The top opening 10U of the box B1 can be opened by pulling up the outer cover 162 together with the inner cover 161 while pressing a finger against the opening T1 which is separated from the upper part of the front plate 13 by this opening. In addition, a break line C2 consisting of a trapezoidal perforation line is formed upward from the fold line L9 at the bottom of the back plate 11, and when discarding the box B1, the part surrounded by this break line C2 is formed. By pressing the opening T2 and breaking it, the bottom cover 17 can be opened, and the box B1 can be easily dismantled. If the outer cover 172 is pulled down together with the inner cover 171 while pressing the finger against the opening T2 which is separated from the lower part of the back plate 11 when the bottom cover 17 is opened, the bottom opening 10D of the box B1 can be opened, and the box B1 can be opened. Can be easily folded.

As explained above, in this packaging box B1, the partition 2 that is integrally provided within the box body 1 is connected to the adhesive piece 15 of the box body 1 from the inner surface of the left side plate 14 that is adhered to the adhesive piece 15. An inner extension plate 21-24 that extends along each inner surface of the front plate 13, right side plate 12, and back plate 11 of the box body 1 and is fixed to the inner surface of the box body 1, and a bottom cover side of the inner extension plate 21-24. Two inner side plates 25 are connected to each other and protrude toward the bottom cover from positions corresponding to the mutually adjacent right side plate 12 and back plate 11 among the four side plates 11-14 of the box body 1 at the end of the box body 1. . The part 26A is separated from the inner extension plate 21-24 so that it can be separated into a substantially V-shape from the remaining part 26B, and a cut line 261 and a fold line 262 are formed between the part 26A and the remaining part 26B. The part 26A is separated from one inner side plate 26 on the back plate 11 side and adhered to the other inner side plate 25 on the right side plate 12 side, and the part 26A is separated from the other inner side plate 25 on the right side plate 12 side. One of the sides and the other side of the right side plate 12 are connected in a substantially V shape, and are formed to be expandable and retractable toward the bottom cover side within the box body 1, supporting the bottom of the vial within the box body 1 and holding the vial in the air. Since the vial is held elastically in a floating state, the vial can be reliably protected from impact from outside the box B1. The partition 2 of this box B1, especially the two inner side plates 25 and 26, are assembled in a substantially V shape between the bottom of the vial and the bottom lid 17 in the box B1, and are expandable and retractable. Therefore, the height between the bottom of the vial and the bottom lid 17 can be arbitrarily adjusted depending on the height and size of the box B, and even for smaller vials, the height of the box B1 can be lowered. This allows the box B1 to be made more compact. For example, it can accommodate a vial with a diameter of 15 mm, a height of 38 mm, and a capacity of 3 ml.

A second embodiment is shown in FIGS. 7 and 8. FIG. 7 shows the structure of the packaging box B2 with a buffer function, and FIG. 8 shows the structure of the blank sheet P2 before the packaging box B2 is assembled. This packaging box B2 has a configuration that is generally the same as that of the first embodiment, and a part of the partition 2 has a configuration that is different from that of the first embodiment. Therefore, in the description of this embodiment, the same reference numerals will be given to the same configurations as those in the first embodiment, redundant explanations will be omitted, and new points that are different from the first embodiment will be explained. The explanation will be given with reference numerals.

As shown in FIGS. 7 and 8, in this packaging box B2, the adhesive piece 15 or the inner extension plate 21-24 protrudes from the end on the canopy side so that it can be held down by the canopy 16, and the vial is held inside the box body 1. It also has an inner top plate 27 that presses the top of the screen.
In this case, the inner top plate 27 (inner top plate shaped part 27P) is the third extension plate 23 (third extension plate shaped part 23P) of the inner extension plates 21-24 (inner extension plate shaped parts 21P-24P). Continuing from the canopy side end, that is, the upper edge, it is formed into a substantially rectangular or substantially trapezoidal shape, in this case a substantially rectangular shape. In this case, a fold line 271 is formed as a ruled line slightly above the upper edge of the third extension plate 23 and parallel to the upper edge.

By doing this, as shown in FIG. 9, when the top opening 10U is closed by the canopy 16, each flap 163, 164, inner lid 161, and outer lid 162 on the top opening 10U side closes the inner top panel. 27 is pushed down and tilted toward the top opening 10U, and this inner top plate 27 presses down the top of the vial from above.
By pressing the top of the vial from above with the inner top plate 27 in this way, the top side of the vial is held elastically, and in addition to the effect of the partition 2 described above, the vial is more securely held in the box B2. is maintained. Therefore, even if the box B2 is subjected to impact from above and below, the vials within the box B2 are less likely to rattle and are more effectively protected within the box B2.
Therefore, according to this packaging box B2, the effects of the first embodiment can be further enhanced.

A third embodiment is shown in FIGS. 10 and 11. FIG. 10 shows the structure of the packaging box B3 with a buffer function, and FIG. 11 shows the structure of the blank sheet P3 before the packaging box B3 is assembled. This packaging box B3 has generally the same configuration as the first embodiment, and has a part of the partition 2 that has a different configuration from the first embodiment. Therefore, in the description of this embodiment as well, the same reference numerals are given to the same components as those in the first embodiment, and overlapping explanations are omitted, and new points that are different from the first embodiment are added. The explanation will be given with reference numerals.

As shown in FIGS. 10 and 11, in this packaging box B3, the fixing portion 232 of the third extension plate 23 is formed to be bendable along the fold line 231H. , this folding line 231H is formed into a substantially hat shape instead of a straight line. In this case, the fold line 231H consists of a substantially hat-shaped cut line.

By making such a folding line 231H, the protrusion 231 (protrusion-shaped portion 231P) is formed on the third extension plate 23 (third extension plate-shaped portion 23P), and the protrusion 231 (protrusion-shaped portion 231P) At approximately the center in the vertical direction of the third extension plate-shaped portion 23P), one side edge on the second extension plate 22 (second extension plate-shaped portion 22P) side, that is, the left edge, and a portion adjacent to this left edge. The fixing portion 232 (fixing portion shaped portion 232P) is formed between the folding line 231H, which is a substantially hat-shaped cut line parallel to the left side edge of the lever, and the folding line 231H described above and the folding line 231H is formed into a substantially rectangular shape by score lines 231b extending from the left edge to the right edge above and below, and score lines 231c extending between the ends of each score line 231b on the right edge.

By doing this, for example, even if the adhesive surface of the fixing part 232 itself is small due to the downsizing of the box and it is not possible to secure a sufficient area (area) for applying the glue, the fixing part 232 can be expanded and the adhesive to be applied with the glue can be expanded.
