Description

Technical Field

[0001] The present invention relates to a packaging box with a buffer function used for packaging pharmaceuticals and various other articles.

Background Art

[0002] Generally, medical pharmaceuticals such as tablets and capsule tablets handled in medical institutions and dispensing pharmacies are stored in a plurality of pieces in a single PTP sheet, and this PTP sheet is further pillow-packed or bundled with a binding band in units of a plurality of sheets and then packaged in a packaging box (individual packing box) as a single unit.

[0003] This type of packaging box is composed of four side plates formed by connecting mutually parallel front, back, left, and right side plates and an adhesive piece formed along one side edge thereof, and a pair of flaps and a lid formed at both end edges of the four side plates, and includes a top lid forming a top surface portion and a bottom lid forming a bottom surface portion. The adhesive piece on one side edge of the four side plates is adhered to the other side edge to be configured. In the process of packaging pharmaceuticals in this way, the four side plates are bent into a quadrangular prism shape, the pharmaceuticals are stored therein, each part of the bottom lid is bent and adhered, and the top surface opening of the box is sealed by the top lid, and it is assembled into a substantially rectangular parallelepiped shape as a whole. Thus, the pharmaceuticals are packaged.

[0004] Previously, this type of medical drug came with a package insert containing various information about the drug, such as its name, how to take it (dosage, administration, etc.), efficacy, and handling precautions, and was included in the packaging box. This package insert was typically printed on relatively large paper, such as A3 size, and was folded into a long, narrow shape to fit inside the box. The folded package insert was relatively thick. This folded package insert was then placed inside the box in a way that it sandwiched the drug. In this manner, the package insert held the drug in place within the box, protecting it from external impacts. However, with the revised Pharmaceuticals and Medical Devices Act of November 2019, the provision of this package insert electronically became the general rule, and this will come into effect in August 2021. In other words, the attachment of package inserts to drugs will be abolished. Since the package insert will no longer be included inside the packaging box, it is inevitable that the previously used box will have empty space where the package insert would normally be. This could cause the medication to rattle around inside the box, potentially reducing its protective performance. Therefore, the design of the previous box needs to be changed. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Utility Model Publication No. 6-53425 [Overview of the project] [Problems that the invention aims to solve]

[0006] The conventional packaging boxes (individual packaging boxes) mentioned above can be made smaller to match the overall size (dimensions) of the pharmaceutical product (a pharmaceutical product consisting of multiple tablets or capsules sealed in PTP sheets and bundled together with cable ties), thus eliminating any gaps inside the box. However, changing the size of these boxes requires not only adjusting the settings of the cartoner (a machine that boxes goods at the same time as making the packaging boxes), but also changing the size of the bulk boxes that hold multiple individual packaging boxes, and the cardboard boxes that hold multiple bulk boxes. As a result, the process of packaging pharmaceutical products involves extensive changes and places a heavy burden on the manufacturer.

[0007] Furthermore, while many designs have been proposed for this type of box that include a cushioning section inside to protect pharmaceuticals, in many cases, the cushioning section is integrated into the box, requiring the use of many box materials (such as cardboard) or the creation of complex shapes in the box materials. This results in increased costs compared to boxes without a cushioning section.

[0008] The present invention solves these conventional problems by enabling the securing of pharmaceuticals within a packaging box of this type, even while leaving a space equivalent to the gap for inserting the conventional package insert, thus eliminating the need to change the size of the box and the resulting impact on other aspects. Furthermore, it aims to provide a buffering function with an extremely simple structure, without using a large amount of box material or applying complex shapes to the box material, thereby effectively protecting the pharmaceuticals inside the box while suppressing cost increases.

[0017] Next, embodiments for carrying out this invention will be described with reference to the figures. Figures 1 and 2 show the first embodiment. Figure 1(a) shows the overall structure of the cushioning packaging box B1, and Figure 1(b) shows the structure of the main parts of the packaging box B1. Figure 2 shows the structure of the blank sheet P1 of the packaging box B1 before assembly. This box B1 is exemplified as packaging for pharmaceutical packs (a set of multiple tablets or capsules contained in one PTP sheet, with multiple PTP sheets further pillow-packed or bound together with cable ties to form a single unit; the same applies hereinafter).

[0018] As shown in Figures 1 and 2, the cushioning packaging box B1 (hereinafter sometimes referred to as packaging box B1 or box B1) is made of so-called cardboard and consists of four side panels 11-14 (back panel 11, left side panel 12, front panel 13, right side panel 14) that are connected to each other in parallel and form the front, back, left side, and right side of box B1, and the side edges of one side panel 11 on one side of these four side panels 11-14 and the other side panel 14 on the other side (the side edge that becomes the side edge on the connecting side) are connected. It consists of an adhesive piece 15 formed in conjunction with one side edge of the connecting side, a pair of flaps 163, 164, 173, 174 formed in conjunction with the end edges of two mutually opposing side plates 12, 14 among these four side plates 11-14, and inner covers 161, 171 and outer covers 162, 172 formed on the end edges of the other two side plates 11, 13 separate from the two side plates 12, 14, and is equipped with a top cover 16 that closes the top opening 10U and a bottom cover 17 that closes the bottom opening 10D.

[0019] In the case of this box B1, the four side panels 11-14 are, from left to right, the back panel 11, the left side panel 12, the front panel 13, and the right side panel 14. One side panel 11 on one side (in this case, the left side) is the back panel 11, and the other side panel 14 on the other side (in this case, the right side) is the right side panel 14. The back panel 11 and the front panel 13 are both vertically elongated rectangles of the same size, while the left and right side panels 12 and 14 are both vertically elongated rectangles of the same size but narrower than the back panel 11 and the front panel 13. The adhesive piece 15 is about one-third the width of each of the left and right side panels 12 and 14, and extends in a roughly trapezoidal shape from the side edge of the back panel 11 on the right side panel 14 side. This adhesive piece 15 is connected to the side of the back panel 11 side of the right side panel 14 on the back surface via glue.

[0020] In the case of this box B1, the top cover 16 consists of an inner cover 161 connected via fold lines L5 from the upper edges of the four side panels 11-14, in this case the upper edge of the back panel 11; an outer cover 162 connected via fold lines L7 from the upper edge of the front panel 13; and a pair of left and right flaps 163 and 164 connected via fold lines L6 and L8 from the upper edges of the left and right side panels 12 and 14, respectively. In this case, the inner cover 161 is formed in a rectangular shape so as to be able to cover almost the entire top opening 10U of the box B1, with an insert piece 1611 protruding from its upper end (tip). The outer cover 162 is formed in a trapezoidal shape so as to be able to cover almost the entire top opening 10U of the box B1. The left and right flaps 163 and 164 are formed in a trapezoidal shape so as to be able to partially cover the top opening 10U of the box B1 (about two-fifths of each side of the top opening 10U). In this way, the top opening 10U is sequentially closed by the inner lid 161 and outer lid 162 via the left and right flaps 163 and 164, and the insert piece 1611 at the tip of the inner lid 161 is inserted into the end on the top lid 16 side of the inner surface of the front panel 13, and the outer lid 162 is glued to the inner lid 161 to seal it. The fold lines L5-L8 of the four side panels 11-14 are formed linearly on the upper edges of the four side panels 11-14 by concave lines extending from the front side to the back side of the box B1, allowing each part of the top lid 16 to be guided to tilt outwards from the top opening 10U.

[0021] In the case of this box B1, the bottom cover 17 consists of an inner cover 171 connected via a fold line L9 from the lower edge of the four side panels 11-14, in this case the lower edge of the back panel 11; an outer cover 172 connected via a fold line L11 from the lower edge of the front panel 13; and a pair of left and right flaps 173 and 174 connected via fold lines L10 and L12 from the lower edges of the left and right side panels 12 and 14, respectively. In this case, the inner cover 171 is formed in a trapezoidal shape so as to be able to partially cover the bottom opening 10U of the box B1 (about 4 / 5 or 3 / 4 of the entire bottom opening 10D). The outer cover 172 is formed in a trapezoidal shape so as to be able to cover almost the entire bottom opening 10U of the box B1. The left and right flaps 173 and 174 are formed in a trapezoidal shape so as to partially cover the bottom opening 10U (both left and right ends) of the box B1 (about 2 / 5 of each side of the bottom opening 10U). In this way, the bottom opening 10U is sequentially closed by the inner lid 171 and outer lid 172 via the left and right flaps 173 and 174, and sealed by gluing the outer lid 172 to the inner lid 171. The fold lines L9-L12 of the four side panels are formed linearly on the lower edges of the four side panels 11-14 by concave lines extending from the front side to the back side of the box B1, allowing each part of the bottom lid 17 to be guided to tilt outwards from the bottom opening 10D.

[0022] In addition, in this box B1, an opening break line C1 is formed on the fold line L7 between the outer lid 162 of the top lid 16 and the front panel 13 to which the outer lid 162 is connected, and a disassembly break line C2 is formed on the fold line L11 between the outer lid 172 of the bottom lid 17 and the front panel 13 to which the outer lid 172 is connected. In this case, the opening break line C1 on the top lid 16 is formed by adding a perforation line c1 in the shape of a rectangular groove (in this case, a horizontally elongated rectangle) from the fold line L7 at a position directly below the center of the fold line L7 between the outer lid 162 and the front panel 13, and then adding perforation lines c2 on the fold line L7 from both ends of the groove-shaped perforation line c1 to both ends of the fold line L7. The part enclosed by the groove-shaped perforation line c1 on the upper part of the front panel 13 is hereinafter referred to as the opening T1. In this case, the tear line C2 for disassembly on the bottom cover 17 side is formed by adding a semicircular groove-shaped perforation line c3 from the fold line L11 at a position directly above the center of the fold line L11 between the outer cover 172 and the front panel 13, and further adding perforation lines c4 on the fold line L11 from both ends of the groove-shaped perforation line c3 to both ends of the fold line L11. The portion enclosed by the groove-shaped perforation line c3 at the bottom of the front panel 13 is hereinafter referred to as the opening T2.

[0023] In this way, the adhesive piece 15 on one side edge of the four side panels 11-14 and the other side panel of the four side panels 11-14, that is, the right side panel 14, are joined together and connected to one side edge on the connecting side of the back panel 11, which is one side panel on one side, and to one side edge on the connecting side of the right side panel 14, which is one side panel on the other side. The bottom opening 10D is closed by the various parts of the bottom cover 17 and the top opening 10U is closed by the various parts of the top cover 16, so that the whole is assembled into a box B1 that is roughly rectangular in shape, and is used to package pharmaceutical packs.

[0024] Furthermore, this box B1 is equipped with a cushioning function section 2 capable of holding and securing the pharmaceutical pack inside the box B1. This cushioning function section 2 consists of a pressing plate 21 that curves outwards from the inner surface of one of the four side panels 11-14 toward the opposite side panel.

[0025] In the case of this box B1, one side panel of the four side panels 11-14 is the back panel 11, and the lids of the top cover 16 and bottom cover 17, in this case the inner covers 161 and 171, are connected to the upper and lower edges of the back panel 11. The retaining plate 21 is connected to one side edge of the inner covers 161 and 171, which are on the extensions of both ends of one side edge on the connecting side of the back panel 11, and encloses the adhesive piece 15, extending around the outer circumference of the adhesive piece 15. It is formed as a roughly rectangular plate that is longer than the length of the back panel 11 and is roughly the same as or slightly shorter than the width of the back panel 11. Fold lines L13 and L14 are attached to the upper and lower ends of this retaining plate 21 at approximately the same positions as the end edges of the four side panels 11-14, more specifically at approximately the same positions as the fold lines L5 and L9 of the upper and lower edges of the back panel 11, respectively, and are on the same straight line as the fold lines L5 and L9 of the upper and lower edges of the back panel 11. In this case, each fold line L13 and L14 is formed by a concave crease line extending from the front side to the back side of box B1. Note that each fold line L13 and L14 may be a perforated line instead of a crease line. In this way, as described later, the presser foot 21 is folded onto the inner surface of each inner lid 161 and 171 and the back panel 11 at one side edge of each inner lid 161 and 171 of the top lid 16 and bottom lid 17, and both the upper and lower ends are glued and fixed to each inner lid 161 and 171. Thus, when box B1 is assembled, the presser foot 21 is curved and protrudes on the inner surface of the back panel 11.

[0026] As shown in Figure 2, this box B1 consists of a single blank sheet P1 formed integrally by punching out cardboard, together with the cushioning function section 2, and has the following configuration.

[0027] On one side, in this case on the left side, a vertically elongated rectangle of a predetermined size, forming the back panel 11 of box B1, is formed as a back panel shape portion 11P. On the right long side of this back panel shape portion 11P, a left side panel shape portion 12P, which is a rectangle with the same length (height) as the back panel shape portion P11 but slightly smaller in width, forming the left side panel 12 of box B1; a front panel shape portion 13P, which is the same size and shape as the back panel shape portion 11P and forms the front panel 13 of box B1; and a right side panel shape portion 14P, which is the same size and shape as the left side panel shape portion 12P and forms the right side panel 14 of box B1, are successively formed via fold lines L1, L2, and L3. Then, on the other long side to the left of the back panel shape portion 11P, a vertically elongated strip, in this case a trapezoidal shape with the other long side to the left as the base, forming an adhesive piece 15, is continuously formed via fold line L4 as an adhesive piece shape portion 15P. Each fold line L1-4 is formed by a concave crease on the blank sheet P1, extending from the front side to the back side. The four side panels are composed of the back panel shape 11P, the left side panel shape 12P, the front panel shape 13P, and the right side panel shape 14P, which include these adhesive piece-shaped parts 15P.

[0028] An inner lid-shaped portion 161P is continuously formed via a fold line L5 on one of the upper short sides of the back panel-shaped portion 11P, forming an inner lid 161 which is rectangular in shape and approximately the same size as the top opening 10U, with an insertable piece 1611 at its upper end (tip). A flap-shaped portion 163P is continuously formed via a fold line L6 on one of the upper short sides of the left side panel-shaped portion 12P, forming a left flap 163 which is a trapezoid slightly shorter than half the length of the outer lid-shaped portion 161P. An outer lid-shaped portion 162P is continuously formed via a fold line L7 on one of the upper short sides of the front panel-shaped portion 13P, forming an outer lid 162 which is a trapezoid slightly shorter in length than the inner lid-shaped portion 161P. A trapezoidal flap-shaped section 164P, approximately the same size as the flap-shaped section 163P, is continuously formed on one of the upper short sides of the right side panel-shaped section 14P via a fold line L8. Each fold line L5-L8 is formed by a concave scribed line from the front side to the back side of the blank sheet P1. The canopy 16 is composed of these outer cover-shaped section 161P, inner cover-shaped section 162P, and the left and right flap-shaped sections 163P and 164P.

[0029] On one of the lower short sides of the back panel shape 11P, an outer lid shape 171P is continuously formed via a fold line L9, forming an inner lid 171 in the shape of a trapezoid whose length is slightly shorter than the depth of the bottom opening 10D. On one of the lower short sides of the left side panel shape 12P, a flap shape 173P is continuously formed via a fold line L10, forming a left flap 173 in the shape of a trapezoid slightly shorter than half the length of the outer lid shape 171P. On one of the lower short sides of the front panel shape 13P, an outer lid shape 172P is continuously formed via a fold line L11, forming an outer lid 172 in the shape of a trapezoid slightly longer than the inner lid shape 171P (in other words, the same size and shape as the outer lid shape 162P of the top lid 16). A lower flap-shaped section 174P, which is approximately the same size as the flap-shaped section 173P and forms the right flap 174, is continuously formed on one of the shorter sides of the lower right side panel-shaped section 14P via a fold line L12. Each fold line L9-L12 is formed by a concave scribed line from the front side to the back side of the blank sheet P1. The bottom cover 17 is composed of these outer cover-shaped section 171P, inner cover-shaped section 172P, and the left and right flap-shaped sections 173P and 174P.

[0030] The retaining plate-shaped part 21P is formed in a roughly rectangular shape that is longer than the length of the back panel-shaped part 11P and is approximately the same width as or slightly shorter than the width of the back panel-shaped part 11P. This is connected to one side edge of the back panel-shaped part 11P on the connection side, i.e., the left side edge (which becomes the right side edge when box B1 is assembled), and to one side edge of each inner lid-shaped part 161P, 171P on the extension of both ends thereof, i.e., the left side edge (which becomes the right side edge when box B1 is assembled), and encloses the adhesive piece-shaped part 15P, extending around the outside of the adhesive piece-shaped part 15P. In this case, the retaining plate-shaped part 21P is formed in a roughly rectangular shape that is longer than the length of the back panel-shaped part 11P and is approximately the same width as or slightly shorter than the width of the back panel-shaped part 11P. In this case, the adhesive piece-shaped portion 15P is formed by cutting out a line 151 that forms the outer shape (trapezoid) of the adhesive piece-shaped portion 15P on one side of the presser plate-shaped portion 21P on the back plate-shaped portion 11P side, that is, on the right side, and cutting it out from the presser plate-shaped portion 21P. Then, at both the upper and lower ends of the presser plate-shaped portion 21P, fold lines L13 and L14 are attached at approximately the same positions as the fold lines L5 and L9 on the upper and lower edges of the back plate-shaped portion 11P, respectively, and are on the same straight line as the fold lines L5 and L9 on the upper and lower ends of the back plate-shaped portion 11P. Note that each fold line L13 and L14 is formed by a concave crease from the front side to the back side of the box B1. The cushioning function portion 2 is formed by this presser plate-shaped portion 21P.

[0031] Then, on the top cover 16 side, a break line C1 for opening is formed at a position directly below the center of the fold line L7 between the outer cover shape portion 162P and the front panel shape portion 13P, by creating a perforated line c1 in the shape of a rectangular groove (in this case, a horizontally elongated rectangle) from the fold line L7, and further, perforated lines c2 are created on the fold line L7 from both ends of the perforated line c1 in the groove shape to both ends of the fold line L7. Also, on the bottom cover 17 side, a break line C2 for disassembling is formed at a position directly above the center of the fold line L11 between the outer cover shape portion 172P and the front panel shape portion 13P, by creating a perforated line c3 in the shape of a semicircular groove from the fold line L11, and further, perforated lines c4 are created on the fold line L11 from both ends of the perforated line c3 in the groove shape to both ends of the fold line L11.

[0032] As shown in Figures 3(1) and (2), the blank sheet P1 is folded so that the retaining plate-shaped portion 21P is folded over the inner surfaces of the upper and lower inner lid-shaped portions 161P and 171P and the back panel-shaped portion 11P by folding the left edges of the upper and lower inner lid-shaped portions 161P and 171P (by mountain folding the left edges of these portions). The upper and lower ends of the retaining plate-shaped portion 21P, in this case the upper and lower ends of the fold lines L13 and L14 on both ends, are glued and fixed to the ends of the upper and lower inner lid-shaped portions 161P and 171P on the back panel-shaped portion 11P side. Then, as shown in Figure 3(2), the surface side of the adhesive piece-shaped portion 15P and the back side of the right side panel-shaped portion 14P are aligned with the side on the back panel-shaped portion 11P side and glued and fixed. Finally, as shown in Figures 4(a) and (b), it is folded into a flat shape so that it can be assembled into the box B1. These flattened, unassembled boxes (Box B1) are packed in cardboard and shipped to users such as pharmaceutical companies.

[0033] Thus, when box B1 is assembled, the retaining plate 21 is curved and protrudes from the inner surface of the back panel 11, and this retaining plate 21 elastically holds and secures the pharmaceutical packs that are packaged inside box B1.

[0034] Figure 5 shows the pharmaceutical product packaged in box B1 at a pharmaceutical company. Note that Figure 5 shows the pharmaceutical product packaged in box B1 with the left side panel 12 of box B1 removed.

[0035] As shown in Figure 1(b), in the pharmaceutical packaging process at a pharmaceutical company, the box B1 is assembled into a box shape, and either the top opening 10U or the bottom opening 10D of the box B1 is closed with a top cover 16 or a bottom cover 17, while the pharmaceutical pack is placed inside the box B1 from the other side which is not closed. When closing the top opening 10U or the bottom opening 10D of the box B1 with a top cover 16 or a bottom cover 17, the flaps 163, 164 or 173, 174, the inner cover 161 or 171, and the outer cover 162 or 172 are folded in sequence onto the top opening 10U or the bottom opening 10D of the box B1, and the outer cover 162 or 172 is glued to the inner cover 161 or 171. Thus, the top cover 16 or the bottom cover 17 is fixed to the top opening 10U surface or the bottom opening 10D surface of the box B1. Then, once the pharmaceutical pack is placed inside box B1, the other of either the top opening 10U or the bottom opening 10D of box B1, that is, the other that is not closed, is closed by the top cover 16 or the bottom cover 17 (see Figure 1(a)).

[0036] When the top opening 10U or bottom opening 10D is closed by the top cover 16 or bottom cover 17, as shown in Figure 5, the retaining plate 21 is curved outwards on the inner surface of the back plate 11, and the pharmaceutical pack is elastically held in place by this retaining plate 21.

[0037] In other words, when the top opening 10U or bottom opening 10D is closed by the top cover 16 or bottom cover 17, the upper end 21U or lower end 21D of the retaining plate 21, which is adhesively fixed to the inner cover 161 or 171 of the top cover 16 or bottom cover 17, rotates toward the top opening 10U or bottom opening 10D with the upper or lower fold line L13 or L14 as the pivot point. As a result, since one of the top cover 16 or bottom cover 17 is already closed, the upper and lower ends 21U and 21D of the retaining plate 21 are folded along the upper and lower fold lines L13 and L14, respectively. These folds compress the area around each fold line L13 and L14 on the inner surface of the retaining plate 21, causing the intermediate portion 21C between each fold line L13 and L14 of the retaining plate 21 to compress and deform toward the vertical center of the retaining plate 21, protruding in a convex curved shape (circular arc cross-section) toward the front panel 13 of the box B1. The pharmaceutical pack stored inside the box B1 is elastically held between this retaining plate 21 and the front panel 13 of the box B1. Then, when the top opening 10U or bottom opening 10D is closed with the top cover 16 or bottom cover 17, as described above, the outer cover 162 or 172 is glued to the inner cover 161 or 171 of the top cover 16 or bottom cover 17, fixing the top cover 16 or bottom cover 17 to the top opening 10U surface or bottom opening 10D surface of the box B1. The top cover 16 and bottom cover 17 maintain the curved deformation of each retaining plate 21 within the box B1, and the pharmaceutical pack is held in place by the fixing of the retaining plates 21 within the box B1, and is held in place by the elastic action of the retaining plates 21. Therefore, even if the box B1 is subjected to an external impact, the pharmaceutical pack will not rattle inside the box B1, and even if the pharmaceutical pack inside the box B1 is subjected to an impact, this impact is absorbed by the elastic action of each retaining plate 21, and the pharmaceutical pack is effectively protected inside the box B1.

[0038] As shown in Figure 1, the packaging box B1 has a break line C1 consisting of a rectangular perforation line extending downward from the fold line L7 at the top of the front panel 13. To open box B1, the top lid 16 can be opened by pressing and breaking the opening T1 in the area enclosed by this break line C1. By pressing a finger against the opening T1 that is separated from the top of the front panel 13 as a result of this opening, the top opening 10U of box B1 can be opened by pulling the outer lid 162 upward together with the inner lid 161. This top opening 10U can then be resealed with the inner lid 161 with the insert tab 1611. Additionally, a break line C2 consisting of a semicircular perforation line extending upward from the fold line L11 is formed at the bottom of the front panel 13. When disposing of box B1, the bottom lid 17 can be opened by pressing and breaking the opening T2 in the area enclosed by this break line C2, making it easier to dismantle box B1. By pressing your fingers against the opening T2, which is separated from the bottom of the front panel 13 when the bottom lid 17 is opened, and pulling down the outer lid 172 together with the inner lid 171, you can open the bottom opening 10D of the box B1 and easily fold the box B1.

[0039] As explained above, this packaging box B1 is equipped with a cushioning function section 2 that can hold and secure the pharmaceutical pack inside the box. Therefore, even if a space equivalent to the gap for inserting the previous package insert is left inside the box B1, the pharmaceutical pack can be securely fixed inside the box B1. This eliminates the need to change the size of the box B1, and resolves the problem of widespread changes and burdens that would result from changing the size of the box B1, such as the need to adjust the settings of the carton, or the need to change the size of the bulk boxes that hold multiple individual boxes, and the cardboard boxes that hold multiple bulk boxes.

[0040] Furthermore, this cushioning function section 2 consists of a retaining plate 21 that curves outwards from the inner surface of one of the four side panels 11-14 toward the opposite side panel. In this case, the inner lids 161 and 171 of the top cover 16 and bottom cover 17 are connected to both ends of the back panel 11, and the retaining plate 21 is connected to the left edges of each inner cover 161 and 171 on the extension of both ends of the left edge of the connecting side of the back panel 11, enclosing an adhesive piece 15 and extending around the outer circumference of the adhesive piece 15, and is formed as a plate longer than the length of the back panel 11 and approximately the same as or slightly shorter than the width of the back panel 11, and the left edges of each inner cover 161 and 171 are folded onto the inner surfaces of each inner cover 161 and 171 and the back panel 11, and both ends are fixed to each inner cover 161 and 171, so that when the box B1 is assembled, the retaining plate 21 curves outwards on the inner surface of the back panel 11. In this way, the cushioning function section 2 has an extremely simple structure, and it can be installed inside box B1 without using a large amount of box material or giving the box material a complex shape.

[0041] Therefore, this packaging box B1 allows for effective protection of the pharmaceutical packs inside the box while keeping costs down.

[0042] Furthermore, in this cushioning function section 2, the retaining plate 21 is formed in a continuous plate shape from the left edge of the connecting side of the back panel 11 and the left edges of the inner lids 161 and 171 on the extensions of both ends thereof. A cut line 151 forming the outer shape of the adhesive piece 15 is formed on one side of the retaining plate 21 on the back panel 11 side, i.e., the right side, and the adhesive piece 15 is cut out from the retaining plate 21 to form the cushioning function section 2 together with the adhesive piece 15, with an extremely simple structure, and without using a large amount of box material inside the box B1 or applying complex shapes to the box material.

[0043] Furthermore, in this cushioning function section 2, the retaining plate 21 has fold lines L13 and L14 on both the upper and lower ends, which are approximately at the same position as the upper and lower edges of the back plate 11 and are on the same straight line as the fold lines L5 and L9 of the upper and lower edges of the back plate 11. Therefore, by simply closing the top opening 10U and bottom opening 10D with the top cover 16 and bottom cover 17, the middle part 21C of the retaining plate 21 between the upper and lower fold lines L13 and L14 can be deformed into a certain curved shape. This ensures that the pharmaceutical pack inside the box B1 is protected stably and reliably.

[0044] In the first embodiment, the inner lids 161 and 171 of the top lid 16 and bottom lid 17 are connected to both ends of one side panel on one side of the four side panels 11-14, in this case the back panel 11. The retaining plate 21 is connected to one side edge of each inner lid 161 and 171 on the extension of both ends of one side edge on the connecting side of the back panel 11, encloses the adhesive piece 15, extends around the outside of the adhesive piece 15, is formed as a plate longer than the length of the back panel 11 and approximately the same as or slightly shorter than the width of the back panel 11, and is folded onto the inner surfaces of each inner lid 161 and 171 and the back panel 11 at one side edge of each inner lid 161 and 171, and both ends are fixed to each inner lid 161 and 171, so that when the box B1 is assembled, the retaining plate 21 protrudes in a curved shape on the inner surface of the back panel 11, but on the four side Since the flaps 164 and 174 of the top cover 16 and bottom cover 17 are connected to both ends of one side panel of the other side of the front panels 11-14, in this case the right side panel 14, the retaining plate may be formed as a plate that is longer than the length of the right side panel 14 and approximately the same width as or shorter than the width of the right side panel 14, by connecting it to one side edge of each flap 164 and 174 on the extensions of both ends of the side edge of the right side panel 14 and extending outwards from the right side panel 14 and each flap 164 and 174, and folded over on the inner surface of each flap 164 and 174 and the right side panel 14 at one side edge of each flap 164 and 174, and fixed at both ends to each flap 164 and 174, so that when box B1 is assembled, the retaining plate protrudes in a curved shape on the inner surface of the right side panel 14. In this case as well, it is preferable that fold lines are made on both ends of the retaining plate at approximately the same positions as the edges of the four side plates 11-14.

[0045] As specific examples, Pattern 1 is shown in Figures 6 and 7, Pattern 2 in Figures 8 and 9, and Pattern 3 in Figures 10 and 11. In each figure, components common to the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0046] In Pattern 1 of Figures 6 and 7, the other side of the four side panels 11-14 is the right side panel 14, and flaps 164 and 174 are formed by connecting them to both the upper and lower edges of the right side panel 14. The retaining plate 21A is connected to one side edge of each flap 164 and 174, which are on the extensions of both ends of one side edge of the connecting side of the right side panel 14, and extends outwards from each flap 164 and 174 and the right side panel 14. It is a roughly rectangular plate that is longer than the length of the right side panel 14 and is roughly the same as or slightly shorter than the width of the right side panel 14, with both ends formed in a roughly trapezoidal shape. In addition, in this retaining plate 21A, a vertically elongated rectangular opening 210 is formed on the side of the right side panel 14 so that the adhesive piece 15 of one side edge of the four side panels 11-14 can be fitted into it. Then, at both the upper and lower ends of the presser foot 21A, fold lines L20 and L21 are attached in approximately the same positions as the edges of both ends of the four side panels 11-14, and more specifically, at approximately the same positions as the fold lines L8 and L12 on the upper and lower edges of the right side panel 14, respectively, and are aligned in the same straight line as the fold lines L8 and L12 on the upper and lower ends of the right side panel 14. In this case, each fold line L20 and L21 is formed by a concave crease line extending from the front side to the back side of the box B1A. Note that each fold line L20 and L21 may be a perforation line instead of a crease line. In this way, the presser foot 21A is folded onto the inner surface (back side) of each flap 164, 174 and the right side panel 14 at one side edge of each flap 164, 174, and its upper and lower ends are glued and fixed to each flap 164, 174. Then, the surface side of the adhesive piece 15 and the opening 210 of the pressing plate 21A are aligned with the side of the back panel 11 on the inner surface of the right side panel 14 and glued and fixed in place. As a result, as described above, it is folded into a flat shape so that it can be assembled into box B1A. In this way, in the pharmaceutical packaging process, the box B1A is raised into a box shape before assembly, and the top opening 10U and bottom opening 10D of box B1 are closed by the top cover 16 and bottom cover 17. When the top opening 10U and bottom opening 10D are closed by the top cover 16 and bottom cover 17, the pressing plate 21A is curved outwards on the inner surface of the right side panel 14, and the pharmaceutical pack is elastically pressed and held in place by this pressing plate 21A.

[0047] This method also produces the same effects and advantages as the first embodiment.

[0048] In the case of pattern 2 in Figures 8 and 9, the other side of the four side panels 11-14 is the right side panel 14, and flaps 164 and 174 are formed by connecting them to both the upper and lower edges of the right side panel 14. The retaining plate 21B is connected to one side edge of the right side panel 14 on the connecting side and to one side edge of each flap 164 and 174 on the extension of both ends thereof, and extends outwards from each flap 164 and 174 and the right side panel 14. It is a roughly rectangular plate that is longer than the length of the right side panel 14 and is roughly the same as or slightly shorter than the width of the right side panel 14, with both ends formed in a roughly trapezoidal shape. A cut line 211 is between the middle part of this retaining plate 21B and the right side panel 14, and a fold line L22 is between the upper and lower ends of this retaining plate 21 and each flap 164 and 174. Fold line L22 is formed by a concave crease on the front side of box B1B, extending from the front side to the back side. Note that this fold line L22 may be replaced with a perforation line. Then, on both the upper and lower ends of the presser foot 21B, fold lines L20 and L21 are placed at approximately the same positions as the edge ends of the four side panels 11-14, more specifically at approximately the same positions as the fold lines L8 and L12 on the upper and lower edges of the right side panel 14, respectively, and are aligned with the fold lines L8 and L12 on the upper and lower ends of the right side panel 14. In this case, each fold line L20 and L21 is formed by a concave crease on the front side of box B1B, extending from the front side to the back side. Note that each fold line L20 and L21 may be replaced with a perforation line. Also, in this pattern 2, the adhesive piece 15B on one side edge of the four side panels 11-14 is a vertically elongated rectangle that is approximately the same size as or slightly smaller than the right side panel 14. In this way, the retaining plate 21B is folded along one side edge of each flap 164, 174 and the right side panel 14, that is, along the fold line L22, onto the inner surface (back side) of each flap 164, 174 and the right side panel 14, and both the upper and lower ends are glued and fixed to each flap 164, 174. Then, the back side of the adhesive piece 15B is aligned with the surface of the right side panel 14 and glued and fixed. As a result, as described above, it is folded into a flat shape so that it can be assembled into the box B1B.In this way, during the pharmaceutical packaging process, the box B1B is raised into a box shape before assembly, and the top opening 10U and bottom opening 10D of the box B1B are closed by the top cover 16 and bottom cover 17. Once the top opening 10U and bottom opening 10D are closed by the top cover 16 and bottom cover 17, the retaining plate 21B is curved outwards on the inner surface of the right side panel 14, and the pharmaceutical pack is elastically held in place by this retaining plate 21B.

[0049] This method also produces the same effects and advantages as the first embodiment.

[0050] In the case of pattern 3 in Figures 10 and 11, one side panel of the four side panels 11-14 is the back panel 11, and there is no adhesive piece 15 on the left side edge of the back panel 11. The other side panel of the four side panels 11-14 is the right side panel 14, and flaps 164 and 174 are formed by connecting them to both the upper and lower edges of the right side panel 14. An adhesive piece 15C is continuously formed on the right side edge in a vertically elongated strip shape via a fold line L23, in this case in a trapezoidal shape with the right side edge (fold line L23) as the base. In this case, the fold line L23 is formed by a concave crease from the front side to the back side of the box B1C. Note that the fold line L23 may be a perforation instead of a crease. The width of the adhesive piece 15C is about one-third the width of each of the left and right side panels 12 and 14. The presser foot 21C is connected via a fold line L22 to one side edge of each flap 164, 174, which are on the extensions of both ends of one side edge on the connecting side of the right side panel 14, and encloses the adhesive piece 15C, extending around the outside of the adhesive piece 15C. It is formed as a roughly rectangular plate that is longer than the length of the right side panel 14 and is roughly the same as or slightly shorter than the width of the right side panel 14, with both ends being roughly trapezoidal. In this case, each fold line L22 is formed by a concave crease line extending from the front side to the back side of the box B1C. Note that each fold line L22 may be a perforation line instead of a crease line. Then, at both the upper and lower ends of the presser foot 21C, fold lines L20 and L21 are attached in approximately the same positions as the edges of both ends of the four side panels 11-14, and more specifically, at approximately the same positions as the fold lines L8 and L12 on the upper and lower edges of the right side panel 14, respectively, and are in the same straight line as the fold lines L8 and L12 on the upper and lower ends of the right side panel 14. In this case, each fold line L20 and L21 is formed by a concave crease from the front side to the back side of the box B1C. Note that each fold line L20 and L21 may be a perforation line instead of a crease. In this way, the presser foot 21C is folded onto the inner surface of each flap 164, 174 and the right side panel 14 at one side edge of each flap 164, 174, that is, at each fold line L22, and both the upper and lower ends are glued and fixed to each flap 164, 174. Then, the side of the back panel 11 facing the right side panel 14 is aligned with the surface of the adhesive piece 15C and glued in place. As a result, as described above, it is folded into a flat shape so that it can be assembled into box B1C.In this way, during the pharmaceutical packaging process, the box B1C is raised into a box shape before assembly, and the top opening 10U and bottom opening 10D of the box B1C are closed by the top cover 16 and bottom cover 17. Once the top opening 10U and bottom opening 10D are closed by the top cover 16 and bottom cover 17, the retaining plate 21C is curved outwards on the inner surface of the right side panel 14, and the pharmaceutical pack is elastically held in place by this retaining plate 21C.

[0051] This method also produces the same effects and advantages as the first embodiment.

[0052] Figures 12 and 13 show a second embodiment. Figure 12 shows the configuration of a blank sheet P2 of a cushioning packaging box B2 before assembly, and Figure 13 shows part of the assembly process of this box B2. This packaging box B2 has a configuration that is generally the same as the first embodiment, but the configuration of the retaining plate 21 has been slightly changed, and an opened indication function part 3 and a crush disposal function part 4 have been added, so the retaining plate 21, the four side panels 11-14, the top lid 16 and the bottom lid 17 have configurations that differ from the first embodiment. Therefore, in the description of this embodiment, components that are common with the first embodiment will be given the same reference numerals and their redundant explanations will be omitted, and points that differ from the first embodiment will be given new reference numerals and explained.

[0053] As shown in Figure 12, in this packaging box B2, the upper and lower fold lines L15 and L16 of the retaining plate 21 are attached parallel to the edges of the four side panels 11-14 at positions different from the edges of the four side panels 11-14 at both the upper and lower ends of the retaining plate 21. In this case, the upper and lower fold lines L15 and L16 of the retaining plate 21 are attached slightly outside the fold lines L5 and L9 of the upper and lower edges of the back panel 11. That is, the upper fold line L15 is attached slightly above the fold line L5 of the upper edge of the back panel 11, and the lower fold line L16 is attached slightly below the fold line L9 of the lower edge of the back panel 11, parallel to the upper and lower fold lines L5 and L9 of the back panel 11. In this case, the upper and lower fold lines L15 and L16 are formed by concave lines extending from the front side to the back side of the box B2. Note that the fold lines L15 and L16 may be perforations instead of score lines. In this way, the presser foot 21 is folded in on the inner surface of each inner lid 161, 171 and the back panel 11 at one side edge of each inner lid 161, 171, as described above (as shown in Figures 13(1) and (2)), and the upper and lower ends 21U and 21D are glued and fixed to each inner lid 161, 171.

[0054] In this way, the deflection allowance of the intermediate portion 21C between each fold line L15 and L16 of the retaining plate 21 increases, and when the box B2 is assembled, the retaining plate 21 is compressed and deformed toward the center in the vertical direction, and the convex curved shape (circular arc shape in cross-section) of this intermediate portion 21C that protrudes toward the front panel 13 of the box B2 becomes larger (compared to the first embodiment). In other words, the amount of protrusion of the retaining plate 21 can be increased. Therefore, even if a space equivalent to the gap for inserting the previous package insert is left inside the box B2, the amount of protrusion of the retaining plate 21 can be adjusted according to the size of this space, thereby securely holding the pharmaceutical pack inside the box B2.

[0055] In this embodiment, the upper and lower fold lines L15 and L16 of the retaining plate 21 are positioned slightly outside the upper and lower fold lines L5 and L9 of the back panel 11. However, if the goal is to reduce the protrusion of the retaining plate 21, the opposite can be done: the fold lines should be positioned slightly inside the upper and lower fold lines L5 and L9 of the back panel 11. That is, the upper fold line should be positioned slightly below the upper fold line L5 of the back panel 11's upper edge, and the lower fold line should be positioned slightly above the lower fold line L9 of the back panel 11's lower edge, both parallel to the upper and lower fold lines L5 and L9 of the back panel 11. In this way, the amount of deflection in the intermediate portion 21C between each fold line of the retaining plate 21 is reduced, and when the box is assembled, the retaining plate 21 is compressed and deformed toward the center in the vertical direction, and the convex curved shape (circular arc shape in cross-section) of this intermediate portion 21C that protrudes toward the front panel 13 of the box becomes smaller (compared to the first embodiment), and the amount of protrusion of the retaining plate 21 can be reduced. Therefore, even if a space equivalent to the gap for inserting the conventional package insert is left inside the box, the amount of protrusion of the retaining plate 21 can be adjusted according to the size of this space, thereby securely holding the pharmaceutical pack inside the box.

[0056] Furthermore, as shown in Figure 12, in this box B2, an opened indicator function unit 3 is attached to a part of the four side panels 11-14, and a crush disposal function unit 4 is provided on the top cover 16, bottom cover 17, and a part of the four side panels 11-14.

[0057] The opened indication function unit 3 is configured such that it has a cutout 31 on one side of the other side of the four side panels 11-14 that are joined with the adhesive piece 15, that is, on the right side panel 14, and an extension plate 32 that is larger than the cutout 31 of the right side panel 14 and is connected to one side edge on the connection side of the right side panel 14, that is, the right edge.

[0058] In this case, the cut-out portion 31 of the right side panel 14 is formed on the right half of the right side of the right side panel 14, in the middle of the vertical direction, with a cut line 310 formed in the shape of a vertically elongated rectangular frame, creating a vertically elongated rectangular cut-out portion 31. The top of this cut line 310 is a perforation line 311, the left side of the middle is a zipper line 312, the right side is a cut line 313 that forms part of the right edge of the right side panel 14, and the bottom is a cut line 314. In this case, the fact that the right side of this cut line 310 is a cut line 313 forms a fold line L17 between the right side panel 14 and the right extension plate 32. In addition, a small opening 140 is formed in a horizontally elongated, roughly rectangular shape (however, the upper edge is curved upwards) in a part of the right side panel 14 directly below the cut-out portion 31, allowing the tip of one finger, such as an index finger, to be inserted.

[0059] In this way, the cut-off section 31 can be separated from the right side panel 14 by inserting an index finger or the like into the opening 140 and pulling the cut-off section 31 upwards. In this case, the cut-off section 31 is an information tag displaying various information about the pharmaceuticals contained in this box B2.

[0060] In this case, the right extension plate 32 of the right side panel 14 consists of a trapezoidal portion 321 that extends from the entire right edge of the right side panel 14 and is slightly smaller than the right half of the right side panel 14, and a rectangular portion 322 that extends from the middle of the right edge of the trapezoidal portion 321 in the vertical direction and is slightly larger than the cut-out portion 31 of the right side panel 14. This extension plate 32 is folded into the inner surface of the right side panel 14 along the fold line L17 of the right edge of the right side panel 14 and fixed in place with adhesive.

[0061] In this way, the extension plate 32 acts as a cover plate that closes the opening left after the cut-out portion 31 has been cut out from the right side panel 14.

[0062] The crush disposal function unit 4 is configured such that each of the left and right side panels 12, 14, the top lid 16, and the bottom lid 17 of the four side panels 11-14 of box B2 is provided with a shape or folding line that guides the folding of each of the left and right side panels 12, 14, the top lid 16, and the bottom lid 17.

[0063] In this case, the left and right flaps 175 and 176 forming the bottom cover 17 are formed to protrude in a roughly M shape so as to partially cover the bottom opening 10D (both left and right ends) of the box B2, and the shape of their leading edges is roughly V-shaped. In this case, the fold lines L18 and L19 between each of the left and right flaps 175 and 176 and each of the left and right side panels 12 and 14 are formed in a wide-angle roughly V shape. The left and right flaps 163 and 164 forming the top cover 16 may also be formed in a similar manner, protruding in a roughly M shape and having a roughly V-shaped leading edge.

[0064] Furthermore, fold lines 41 and 42 are formed in the center of the width direction of each of the left and right side panels 12 and 14, consisting of linearly extending fold lines, cuts, or combinations thereof, which guide the folding of each side panel 12 and 14, allowing them to be folded into a flat shape. In this case, on the left side panel 12, the fold line 41 is formed continuously in the vertical direction in the center of the width direction of the left side panel 12. On the right side panel 14, the fold line 42 is formed intermittently in the vertical direction above and below the cutout portion 31 on the right side panel 14. In the case of this box B2, instead of the break line C2 for disassembly on the front panel 13, a break line C3 for disassembly is provided on the back panel 11. In this case, the break line C3 is formed on the lower part of the back panel 11 by making a perforated line c3 in the shape of a convex arc extending upward from both lower corners of the back panel 11.

[0065] Furthermore, in the depth direction (vertical direction) center of each inner lid 161, 171 and outer lid 162, 172 of the top lid 16 and bottom lid 17, fold lines 43, 44, 45, 46 are formed, each consisting of a linearly extending scribe line, cut, or combination thereof, which guides each inner lid 161, 171 and outer lid 162, 172 to be folded, allowing the entire box B2 to be folded into a flat shape. Similarly, in the width direction center of each left and right flaps 163, 164, 175, 176 of the top lid 16 and bottom lid 17, fold lines 47, 48, 49, 50 are formed, each consisting of a linearly extending scribe line, cut, or combination thereof, which guides each flap 163, 164, 175, 176 to be folded, allowing each flap 163, 164, 175, 176 to be folded into a flat shape.

[0066] In this case, a fold line 43 is continuously formed in the center of the depth direction (vertical direction) of the inner lid 161 of the canopy 16. Fold lines 45 are intermittently formed at both the left and right ends in the center of the depth direction (vertical direction) of the outer lid 162 of the canopy 16. Fold lines 47 and 48 are intermittently formed in the center of the width direction of the left and right flaps 163 and 164 of the canopy 16.

[0067] In this case, a fold line 44 is continuously formed in the center of the depth direction (vertical direction) of the inner lid 171 of the bottom lid 17. Fold lines 46 are intermittently formed at both the left and right ends in the center of the depth direction (vertical direction) of the outer lid 172 of the bottom lid 17. Fold lines 49 and 50 are continuously formed in the center of the width direction of each flap 175 and 176 toward the center of the V-shape at the leading edge of each flap 175 and 176.

[0068] As the box B2 is equipped with crush disposal functions 4 in each part, the box B2 can be flattened or folded by lightly striking the front panel 13 toward or toward the back panel 11, or by pressing the left and right edges of the front panel 13 toward or toward the back panel 11, thereby applying slight pressure to the front panel 13 toward or toward the back panel 11.

[0069] In the above embodiments, boxes B1 and B2 are exemplified as a so-called four-flap type, where the top lid 16 and bottom lid 17 consist of a pair of flaps, an inner lid, and an outer lid. However, boxes B1 and B2 may also be a so-called three-flap type, where the top lid 16 and bottom lid 17 consist of a pair of flaps and a lid. Even with a three-flap type, the cushioning function unit 2, the opened indication function unit 3, and the crush disposal function unit 4 can be applied in the same way as in the above embodiments, and the same effects and advantages can be achieved. Furthermore, whether boxes B1 and B2 are a four-flap type or a three-flap type, one or the other side of the four side panels may be the back panel, the front panel, or the left and right side panels. Regardless of the orientation of one or the other side of the four side panels, the retaining plate 21 can be provided in the same way by providing lids or flaps on both ends of one or the other side of the four side panels, and the same effects and advantages can be achieved as in the above embodiments.

[0070] Furthermore, although the above embodiments illustrate boxes B1 and B2 as packaging for pharmaceutical packs, boxes B1 and B2 may also be used to package various other items besides pharmaceutical packs. In this case as well, by providing the cushioning function section 2, the opened indication function section 3, and the crush disposal function section 4 in the same manner as in the above embodiments, the same effects and advantages as in the above embodiments can be achieved.

[0071] Figures 14 and 15 show a third embodiment. Figure 14 shows the overall configuration of the cushioning packaging box B3 (hereinafter sometimes simply referred to as packaging box B3 or box B3). In Figure 14, in order to also show the internal configuration of the packaging box B3 after assembly, the assembled packaging box B3 is shown with a part of the front panel 44 (opening lid 440) opened together with the top panel 43. Figure 15 shows the configuration of the blank sheet P3 of the packaging box B3 before assembly. This box B3 is exemplified as being for packaging 10 ampoules, 10 (or 14) PTP sheets with 10 pockets, or 100 (or 140) tablets.

[0072] As shown in Figure 14, in the case of this box B3, the four side panels 41-44 consist of a bottom panel 41, a back panel 42, a top panel 43, and a front panel 44, in order from one side (in this case, the bottom side). One side panel of these four side panels 41-44 has an adhesive piece 45 that is continuous with the bottom panel 41 in this case. The bottom panel 41 and the top panel 43 are both elongated rectangles of the same size, and the back panel 42 and the front panel 44 are both elongated rectangles of the same size. The adhesive piece 45 consists of an adhesive portion 451 that is sized to fit within the surface of the other side panel, in this case the front panel 44, on one side edge of the bottom panel 41 on the adhesive side of the four side panels 41-44, and two extensions 452 and 453 that extend from both the left and right ends of the adhesive portion 451 and are sized to fit into the openings at both ends. In this case, since one side panel is the bottom panel 41, the adhesive portion 451 is connected to the side edge of the bottom panel 41 on the front panel 44 side and is formed as a horizontally elongated rectangle approximately the same size as the inner surface of the front panel 44. A groove-shaped notch 450 is formed on the side edge opposite to the bottom panel 41, so that the whole is formed as an approximately U-shape (an approximately U-shape oriented horizontally with the notch 450 facing upwards) approximately the same size as the front panel 44. The notch 450 is formed as a trapezoidal groove (in this case, an inverted trapezoid with a longer top base and a shorter bottom base), and both the left and right ends of this notch 450, in this case the left and right parts of the side edge of the adhesive portion 451 on the top panel 43 side, are formed at a slight angle toward the notch 450. The two extensions 452 and 453 are each formed at both the left and right ends of the adhesive portion 451 in an approximately trapezoidal shape large enough to cover approximately the entire openings at both ends. In this adhesive piece 45, fold lines L53 and L54 (see Figure 15) are made between the adhesive portion 451 and the left and right extension portions 452 and 453, at positions corresponding to the fold lines L47, L49, L51 (see Figure 15) and L48, L50, L52 (see Figure 15) of the right and left end panels 46 and 47, which will be described later. These fold lines L53 and L54 each consist of a concave scribed line or intermittent cuts or a combination thereof, extending from the outer surface to the inner surface of the box B3. Thus, in this adhesive piece 45, the left and right corners of the lower part of the outer surface of the adhesive portion 451, that is, the lower part of the outer surface of the adhesive portion 451, and the left and right corners of the lower part of the inner surface of the front panel 44, that is, the lower part of the inner surface of the front panel 44, are connected via adhesive.(Please refer to Figure 15 for the symbols in parentheses in the following explanation.)

[0073] In the case of this box B3, the rightmost end panel 46 is connected to the right edge of the bottom panel 41 via a fold line (L47) and has a roughly trapezoidal small flap (461) that can cover a part of the opening at the right end (about one-fifth or one-quarter of the entire opening at the right end), and the rightmost end panel 43 is connected to the right edge of the top panel 43 via a fold line L51 and has a roughly trapezoidal small flap 465 that can cover a part of the opening at the right end (about one-fifth or one-quarter of the entire opening at the right end), and the rightmost end of the back panel 42 It consists of a roughly trapezoidal large flap 463 connected via a fold line (L49) that can cover almost the entire opening at the right end (about 4 / 5 or 3 / 4 of the entire opening at the right end). The opening at the right end is sequentially closed by the large flap 463 of the back panel 42 and the right end extension 452 of the adhesive piece 45 via the upper and lower small flaps (461) and 465, and is sealed by gluing the right end extension 452 to the large flap 463 and small flaps 465. In this case, the fold line (L47) on the right edge of the bottom panel 41 is a concave crease that runs from the outer surface (front (hereinafter the same)) side of the box B3 to the inner surface (back (hereinafter the same)) side. The fold line L51 on the right edge of the top panel 43 is a zipper line. The fold line (L49) on the right edge of the back panel 42 is a concave crease that runs from the outer surface (front (hereinafter the same)) side of the box B3 to the inner surface (back (hereinafter the same)) side. In this case, there is no flap or anything similar at the right end of the front panel 44.

[0074] In the case of this box B3, the left end panel 47 is connected to the left edge of the bottom panel 41 via a fold line (L48) and has a roughly trapezoidal small flap (462) that can cover a part of the left end opening (about one-fifth or one-quarter of the entire left end opening), the top panel 43 is connected to the left edge via a fold line L52 and has a roughly trapezoidal small flap 466 that can cover a part of the left end opening (about one-fifth or one-quarter of the entire left end opening), and the back panel 42 is connected to the left edge It consists of a roughly trapezoidal large flap 464 connected via a fold line (L50) that can cover almost the entire left end opening (about 4 / 5 or 3 / 4 of the entire left end opening). The left end opening is sequentially closed by the large flap 464 of the back panel 42 and the left end extension 453 of the adhesive piece 45 via the upper and lower small flaps (462) and 466, and sealed by gluing the left end extension 453 to the large flap 464 and small flaps 466. In this case, the fold line (L48) on the left edge of the bottom panel 41 is a concave crease running from the outer side to the inner side of the box B3. The fold line L52 on the left edge of the top panel 43 is a zipper line. The fold line (L50) on the left edge of the back panel 42 is a concave crease running from the outer side to the inner side of the box B3. Also, in this case, there is no flap or anything on the left end of the front panel 44.

[0075] In this way, the front panel 44 on the other side of the four side panels 41-44 is bonded to the adhesive piece 45 connected to the bottom panel 41 on one side of the four side panels 41-44, connecting the four side panels 41-44. The opening at the right end is closed with the right end panel 46, and the opening at the left end is closed with the left end panel 47, thereby assembling the whole into a box B3 that is horizontally elongated and roughly rectangular in shape with a small depth, allowing for the packaging of pharmaceuticals.

[0076] Furthermore, as will be described later, in this box B3, groove-shaped notches 450 and 510 are provided on the upper edges of the adhesive piece 45 and the retaining plate 51, so that a cut line 441 is formed on the front plate 44 on the other side of the four side plates 41-44, allowing the front plate 44 to be opened at least at positions facing the notches 450 and 510 when box B3 is assembled, and an opening lid (hereinafter referred to as the opening lid 440) is provided as an opening cut section 440.

[0077] In this case, two short notches 4411 are cut parallel to the top panel 43 at a distance that can be grasped with a fingertip, in the lengthwise (left-right direction) center of one side edge of the connecting side, in this case the lower side edge, forming part of the cut line 441, and a gripping portion 4401 is formed between each notch 4411. Furthermore, two zipper lines 4412 are cut diagonally toward the left and right edges of the front panel 44 toward the top panel 43, forming the remainder of the cut line 441, and an opening flap 440 that widens towards the top panel 43 is formed between each zipper line 4412. In this case, zipper lines are formed on the fold lines L51 and L52 between the top panel 43 and the left and right flaps 465 and 466, respectively, so that the top panel 43 can be cut open together with the opening flap 440. In this way, two cut lines 441 and two fold lines L51 and L52, consisting of zipper lines, are provided between the front panel 44 and the top panel 43 on the other side of the four side panels 41-44 to form the opening lid 440. Thus, by grasping the tab 4401 of the front panel 44 and pulling it up from each cut 4411, the opening lid 440 is cut open along each zipper line 4412 and further along each fold line (zipper line) L51 and L52, opening the front panel 44 or the space between the front panel 44 and the top panel 43 as an opening for dispensing the medicine.

[0078] Furthermore, a groove-shaped notch 442 is made in the center of the base of the tab portion 4401 of the opening lid 440, in other words, in the center between the tab portions 4401 of the two zipper wires 4412, and a locking claw 443 is formed within this notch 442. Fold lines are formed from each end of this notch 442 toward each tab portion 4401 of each zipper wire 4412, so that the locking claw 443 can be raised toward the inner surface of the opening lid 440 by pulling up the tab portion 4401. An engaging portion 454 is provided on the adhesive piece 45 corresponding to this locking claw 443. In this case, the engaging portion 454 is formed on the lower side of the bottom plate 41 side of the adhesive piece 45, which is in a position corresponding to the locking claw 443 when the box B3 is assembled. It consists of a notch 4541 that extends in an arc shape in the left-right direction to allow insertion of the locking claw 443 and a notch 4542 of an appropriate length that extends linearly from the left and right ends and the center toward the bottom plate 41. In this way, the locking claw 443 can be inserted and locked to the inner surface of the opening lid 440 through the arc-shaped engaging portion 454 of the adhesive piece 45, and these locking claw 443 and engaging portion 454 act as a stopper after the opening lid 440 is opened.

[0079] Furthermore, in this box B3, a break line (C4) for opening and disassembly is formed on the fold line (L49) between the large flap 463 of the right end panel 46 and the back panel 42 to which the large flap 463 is connected, and a break line (C5) for opening and disassembly is formed on the fold line (L50) between the large flap 464 of the left end panel 47 and the back panel 42 to which the large flap 464 is connected. On the right end panel 46 side, a perforation line (c41) is made in the shape of a rectangular (inverted trapezoid in this case) groove from the fold line (L49) at a position directly below the center of the fold line (L49) between the large flap 463 and the back panel 42, and further perforation lines (c42) are made from both ends of this groove-shaped perforation line (c41) to both ends of the fold line (L49), forming an opening 421. The break line (C5) on the left end panel 47 side is symmetrical to the break line (C4) on the right end panel 46 side. A perforation line (c51) is made in the shape of a rectangular (in this case, trapezoidal) groove from the fold line (L50) at a position directly above the center of the fold line (L50) between the large flap (464) and the back panel 42. Furthermore, perforation lines (c52) are made from both ends of this groove-shaped perforation line (c51) to both ends of the fold line (L50), forming an opening (422).

[0080] Furthermore, this box B3 also includes a cushioning function section 5 capable of holding and retaining pharmaceuticals within the box B3. This cushioning function section 5 consists of a pressing plate 51 that curves outwards from the inner surface of one of the four side panels 41-44, in this case the adhesive piece 45, toward the opposite side panel, in this case the back panel 42.

[0081] The retaining plate 51 is provided in a size that allows it to be positioned within the surface of the adhesive piece 45, connected to each side edge opposite to the bottom plate 41 by the extensions 452 and 453 of the adhesive piece 45. In this case, it is formed symmetrically with a virtual straight line connecting the upper side edges as the center of symmetry. Groove-shaped notches 450 and 510 are provided on the mutually opposing upper side edges of the adhesive piece 45 and the retaining plate 51, and these notches 450 and 510 are formed symmetrically.

[0082] In this case, the presser plate 51 is formed to be approximately the same size and shape as the adhesive piece 45, by continuing through fold lines L45 and L46, which are cuts on approximately half of each upper edge on the adhesive portion 451 side of the left and right extensions 452 and 453 of the adhesive piece 45, on the upper edges opposite to the bottom plate 41, and is continuous with the adhesive piece 45. In this case, as previously described, the adhesive piece 45 consists of an adhesive portion 451 and extensions 452 and 453 on both the left and right ends, so the presser plate 51 consists of a presser plate body portion 511 corresponding to the adhesive portion 451 of the adhesive piece 45 and two presser plate fixing portions 512 and 513 corresponding to the extensions 452 and 453 of the adhesive piece 45. The adhesive portion 451 is formed as a horizontally elongated rectangle with approximately the same size as the front plate 44, and a groove-shaped notch 450 is formed on its upper edge, so that the whole is formed in a roughly U-shape with approximately the same size as the front plate 44. Similarly, the presser plate body portion 511 is formed as a horizontally elongated rectangle with approximately the same size as the adhesive portion 451, and a groove-shaped notch 510 is formed on its upper edge corresponding to the notch 450 on the upper edge of the adhesive portion 451, so that the whole is formed in a roughly U-shape with approximately the same size as the adhesive piece 45. Here, the notch 510 is formed in a trapezoidal groove shape, similar to the notch 450 of the adhesive piece 45, and both ends of this notch 510, that is, the left and right parts of the upper edge of the presser plate body portion 511, are formed at a slight angle toward the notch 510. Furthermore, since the two extensions 452 and 453 are each formed in a roughly trapezoidal shape at both the left and right ends of the adhesive portion 451, with a size that can cover almost the entire openings on both sides, the two presser plate fixing portions 512 and 513 are also formed in a roughly trapezoidal shape at both the left and right ends of the presser plate body portion 511, with a size that can cover almost the entire openings on both sides. In addition, on this presser plate 51, fold lines L55 and L56 (see Figure 15) are attached between the presser plate body portion 511 and the left and right presser plate fixing portions 512 and 513 at the same positions as the fold lines L53 and L54 (see Figure 15) of the adhesive piece 45, that is, at positions corresponding to the fold lines L47, L49, L51 (see Figure 15) and L48, L50, L52 (see Figure 15) of the right and left end face plates 46 and 47, which will be described later. These fold lines L55 and L56 each consist of concave lines, intermittent cuts, or a combination thereof, extending from the outer side to the inner side of box B3.The retaining plate 51 is folded onto the inner surface of the adhesive piece 45, and the retaining plate fixing parts 512 and 513 at both the left and right ends are adhered and fixed to the inner surfaces of the extensions 452 and 453 of the adhesive piece 45 via adhesive. Thus, when box B3 is assembled, the retaining plate 51 is positioned so that the main body portion 511 of the retaining plate 51 curves outwards toward the back panel 42 on the inner surface of the adhesive piece 45.

[0083] This box B3, along with the cushioning function section 5, consists of a single blank sheet P3 formed integrally by punching out cardboard. As shown in Figure 15, this blank sheet P3 is composed of four side panel sections 41P-44P, including an adhesive piece-shaped section 45P and a pressing plate-shaped section 51P, as well as a right end panel-shaped section 46P and a left end panel-shaped section 47P. Note that in Figure 15, the blank sheet P3 is oriented horizontally, so the top, bottom, left, and right directions of each part of the blank sheet P3 are referred to in this orientation. Incidentally, if this blank sheet P3 is oriented vertically with the front panel-shaped section 44P at the bottom, it matches the top, bottom (top, bottom) and left, and right directions of the parts of the box B3 that have already been described.

[0084] 4. The side panel shapes 41P-44P have a narrow, vertically elongated rectangle of a predetermined size on one side, in this case the left side (when the box B3 is assembled and in the correct orientation, it is a horizontally elongated rectangle as described above), which forms the bottom panel 41 of the box B3. On the right long side of this bottom panel shape 41P, there is a wide, vertically elongated rectangle with the same length (height) as the bottom panel shape 41P but with a larger width (when the box B3 is assembled and in the correct orientation, it is a horizontally elongated rectangle as described above). When oriented in this way, the back panel shape portion 42P, which forms the back panel 42 of box B3 (a horizontally elongated rectangle) as described above, the top panel shape portion 43P, which forms the top panel 43 of box B3 with the same size and shape as the bottom panel shape portion 41P, and the front panel shape portion 44P, which forms the front panel 44 of box B3 with the same size and shape as the back panel shape portion 42P (excluding the left and right end face shapes portions 46P and 47P) are successively formed via fold lines L41, L42, and L43. Note that each fold line L41-L43 is formed by a concave crease line from the outer side to the inner side of the blank sheet P3 (box B3).

[0085] Then, on one of the longer sides of the left side of the bottom plate-shaped portion 41P, the adhesive piece-shaped portion 45P that forms the adhesive piece 45 of the box B3 and the presser plate-shaped portion 51P that forms the presser plate 51 of the box B3 are successively formed via fold lines L44, L45, and L46.

[0086] In this case, the adhesive piece shape portion 45P is formed in the four side plate shape portions 41P-44P by being connected via a fold line L44 to one side edge of the left bottom plate shape portion 41P, that is, the left side edge, and forms an adhesive portion 451P that is sized to be placed within the surface of the right front plate shape portion 44P, and two extension portion shape portions 452P and 453P that extend from both the upper and lower edges of the adhesive portion shape portion 451P via fold lines L53 and L54 and form extension portions 452 and 453 that are sized to be placed in the openings at both the left and right edges of the box B3. The adhesive portion 451P is connected to the left side edge of the bottom plate portion 41P and is formed as a wide, vertically elongated rectangle with approximately the same size as the inner surface of the front plate portion 44P. A groove-shaped notch 450 is formed on the side edge opposite to the bottom plate portion 44P, i.e., the left side edge, so that the whole is formed into a roughly U-shape with approximately the same size as the front plate portion 44P. Here, the notch 450 is formed as a horizontally oriented inverted trapezoidal groove, and both ends of this notch 450, i.e., the upper and lower parts of the left side edge of the adhesive portion 451P, are formed at a slight angle toward the notch 450. The two extension portions 452P and 453P are each formed on the upper and lower end edges of the adhesive portion 451P in a roughly trapezoidal shape large enough to cover approximately the entire openings on both the left and right end edges of the box B3. Each fold line L44 is formed by a concave crease on the blank sheet P3 (box B3) from the outer side to the inner side. Each fold line L45 and L46 is formed by a concave crease or by intermittent cuts on the blank sheet P3 (box B3) from the outer side to the inner side.

[0087] In this case, the retaining plate-shaped portion 51P is formed symmetrically with respect to a virtual straight line connecting the left edges, via fold lines L45 and L46, between the side edges opposite to the bottom plate-shaped portion 41P at each extension-shaped portion 452P and 453P of the adhesive piece-shaped portion 45P, i.e., between the left edges. Groove-shaped notches 450 and 510 are provided on the mutually opposing side edges of the adhesive piece-shaped portion 45P and the retaining plate-shaped portion 51P. Here, the retaining plate-shaped portion 51P is connected via fold lines L45 and L46 to approximately half of each side edge on the adhesive piece-shaped portion 451 side at each side edge opposite to the bottom plate-shaped portion 41P at both the upper and lower ends of the adhesive piece-shaped portion 45P, i.e., the left edge, and is formed to be approximately the same size and shape as the adhesive piece-shaped portion 45P. In this case, as previously described, the adhesive piece shape portion 45P consists of an adhesive part shape portion 451P and extension part shape portions 452P and 453P at both the upper and lower ends. Therefore, the presser plate shape portion 51P consists of a presser plate body shape portion 511P corresponding to the adhesive part shape portion 451P of the adhesive piece shape portion 45P, and two presser plate fixing part shape portions 512P and 513P corresponding to the respective extension part shape portions 452P and 453P of the adhesive piece shape portion 45P. Then, the adhesive portion 451P is formed as a wide, vertically elongated rectangle of approximately the same size as the front plate shaped portion 44P, and a groove-shaped notch 450 is formed in the center of the side edge opposite to the bottom plate shaped portion 41P, so that the whole is formed in a roughly U-shape of approximately the same size as the front plate shaped portion 44P. Similarly, the presser plate body shaped portion 511P is formed as a wide, vertically elongated rectangle of approximately the same size as the adhesive portion 451P, and a groove-shaped notch 510 is formed in the center of the side edge on the adhesive portion shaped portion 451 side, so that the whole is formed in a roughly U-shape of approximately the same size as the adhesive piece shaped portion 45P. Here, the notch 510 is formed in a trapezoidal groove shape, similar to the adhesive piece shaped portion 45P, and both ends of this notch 510, that is, the upper and lower parts of the right side edges of the presser plate body shaped portions 512P and 513P, are formed at a slight angle toward the notch 510.Furthermore, the two extension-shaped parts 452P and 453P are each formed in a roughly trapezoidal shape with a size that can cover substantially the entire openings at the left and right ends of box B3 via fold lines L53 and L54 at both the upper and lower ends of the adhesive-shaped part 451P, and the two presser plate fixing-shaped parts 512P and 513P are each formed in a roughly trapezoidal shape with a size that can cover substantially the entire openings at the left and right ends of box B3 via fold lines L55 and L56 at both the upper and lower ends of the presser plate body-shaped part 511P. Note that the fold lines L55 and L56 are formed by concave lines or intermittent cuts from the outer side to the inner side of the blank sheet P3 (box B3).

[0088] On the right side end panel section 46P, a small flap section 461P is continuously formed via a fold line L47 on the upper edge of the bottom panel section 41P, forming a trapezoidal small flap 461 large enough to cover a portion of the bottom panel 41 side of the opening at the right end of the box B3 after assembly. A large flap section 463P is continuously formed via a fold line L49 on the upper edge of the back panel section 42P, forming a trapezoidal large flap 463 large enough to cover almost the entire area of ​​the opening at the right end of the box B3 after assembly. A small flap section 465P is continuously formed via a fold line L51 on the upper edge of the top panel section 43P, forming a small flap 465 small flap with the same size and shape as the small flap section 461P. These are arranged in a horizontal row along the upper short side of each of the three side panel sections 41P-43P of the four side panel sections 41P-44P. Furthermore, in the case of this end plate-shaped portion 46P, since adhesive (hot melt) is applied to the outer surfaces of the large flap-shaped portion 463P and the small flap-shaped portion 465P during the pharmaceutical company's packaging process, one end of the large flap-shaped portion 463P on the side of the small flap-shaped portion 465P is cut short so that the small flap-shaped portion 465P is exposed. Note that each fold line L47 and L49 is formed by a concave crease line from the outer side to the inner side of the blank sheet P3 (box B3). Fold line L51 is formed by the zipper line 431.

[0089] The left end panel shape portion 47P is configured symmetrically above and below the right end panel shape portion 46P and the three side panel shapes portions 41P-43P. A small flap shape portion 462P is continuously formed via a fold line L48 at the lower edge of the bottom panel shape portion 41P, forming a trapezoidal small flap 462 large enough to cover a portion of the left end opening on the bottom panel 41 side after assembly into box B3. The lower edge of the back panel shape portion 42P covers almost the entire left end opening after assembly into box B3. A large flap-shaped section 464P, which forms a large flap 464 in a trapezoidal shape large enough to cover the area, is continuously formed via a fold line L50. A small flap-shaped section 466P, which forms a small flap 466 with the same size and shape as the small flap-shaped section 462P, is continuously formed via a fold line L52 on the lower edge of the top plate-shaped section 43P. These are arranged in a horizontal row along one of the lower short sides of the three side plate-shaped sections 41P-43P of the four side plate-shaped sections 41P-44P. In the case of this end plate-shaped section 47P, since glue (hot melt) is applied to the outer surfaces of the large flap-shaped section 464P and the small flap-shaped section 466P during the pharmaceutical company's packaging process, one end of the large flap-shaped section 464P on the side of the small flap-shaped section 466P is cut short so that the small flap-shaped section 466P is exposed. Each fold line L48 and L50 is formed by a concave crease on the blank sheet P3 (box B3) from the outer side to the inner side. Fold line L52 is formed by the zipper line 432.

[0090] Furthermore, the four side panel sections 41P-44P are provided with an opening lid section 440P, which forms an opening lid 440. This opening lid section 440P is provided on the front panel section 44P, with a cut line 441 formed so that the positions opposite at least the adhesive piece 45 of the front panel 44 and the notches 450 and 460 of the retaining plate 46 of the box B3 can be opened when the box B3 is assembled.

[0091] In this case, two short notches 4411 are cut parallel to the top panel shape 43P at a distance that allows them to be grasped with fingertips, in the center of the right edge in the vertical direction of the front panel shape 44P, forming a part of the cut line 441, and a handle shape 4401P is formed between each notch 4411. Further, two zipper lines 4412 are cut diagonally toward the upper and lower edges of the front panel shape 44P in the direction of the top panel shape 43P, forming the remainder of the cut line 441, and an opening lid shape 440P is formed between each zipper line 4412, extending from the front panel shape 44P toward the top panel shape 43P. In this case, zipper lines 431 and 432 are formed on the fold lines L51 and L52 between the top panel-shaped section 43P and the upper and lower small flap-shaped sections 465P and 466P, respectively, so that the top panel-shaped section 43P can be cut open together with the opening lid-shaped section 440P. In this way, two cut lines 441 for forming an opening and two zipper lines 431 and 432 are cut between the right front panel-shaped section 44P of the four side panel-shaped sections 41P-44P and the top panel-shaped section 43P, thereby forming the opening lid-shaped section 440P.

[0092] In this case, a groove-shaped notch 442 is made in the center of the base of the knob-shaped portion 4401P of the opening lid-shaped portion 440P, that is, in the center between the ends of the two zipper wires 4412 on the knob-shaped portion 4401P side, and a locking claw-shaped portion 443P is formed within this notch 442, forming a locking claw 443. Fold lines are formed from each end of this notch 442 toward each end of each zipper wire 4412 on the knob-shaped portion 4401P side, so that the locking claw-shaped portion 443P can be raised toward the inner surface of the opening lid-shaped portion 440P. In addition, an engaging portion 454 is provided on the adhesive piece-shaped portion 45P corresponding to this locking claw-shaped portion 443P. In this case, the engaging portion 454 is formed by a notch 4541 that extends in an arc in the vertical direction, allowing the locking claw-shaped portion 443P to be inserted, at the vertical center of the side of the adhesive piece-shaped portion 45P on the bottom plate-shaped portion 41P side, where the box B3 is assembled and the position corresponds to the locking claw-shaped portion 443P, and by appropriately short notches 4542 that extend linearly from the upper and lower ends and the center of this notch 4541 toward the bottom plate-shaped portion 41P.

[0093] Furthermore, the four side panel sections 41P-44P are also provided with opening sections 421P and 422P on the back panel section 42P, which have perforations that allow the left and right end panels 46 and 47 to be opened when the box B3 is assembled, forming openings 421 and 422.

[0094] In this case, a break line C4 for opening and disassembling is formed on the fold line L49 between the large flap-shaped portion 463P of the right end panel-shaped portion 46P and the back panel-shaped portion 42P to which the large flap-shaped portion 463P is connected, and a break line C5 for opening and disassembling is formed on the fold line L50 between the large flap-shaped portion 464P of the left end panel-shaped portion 47P and the back panel-shaped portion 42P to which the large flap-shaped portion 464P is connected. On the right end panel-shaped portion 46P side, the break line C4 is positioned directly below the center of the fold line L49 between the large flap-shaped portion 463P and the back panel-shaped portion 42P. A perforation line c41 is then added from the fold line L49 in the shape of a rectangular groove (in this case, an inverted trapezoid). Furthermore, perforation lines c42 are added from both ends of this groove-shaped perforation line c41 to the fold line L49, so that an opening-shaped portion 421P is formed within the groove-shaped perforation line c41. On the left end panel shape portion 47P side, the break line C5 is symmetrical to the break line C4 on the right end panel shape portion 46P side. A perforation line c51 is made in the shape of a rectangular (in this case, trapezoidal) groove from the fold line L50, directly above the center of the fold line L50 between the large flap shape portion 464P and the back panel shape portion 42P. Furthermore, perforation lines c52 are made from both ends of this groove-shaped perforation line c51 to both ends of the fold line L50, forming an opening shape portion 422P within the groove-shaped perforation line c51.

[0095] As shown in Figure 16, the blank sheet P3 is folded so that the presser plate-shaped portion 51P is folded onto the inner surface of the adhesive piece-shaped portion 45P, and the presser plate fixing portion-shaped portions 512P and 513P are glued and fixed to the inner surfaces of the extension portion-shaped portions 452P and 453P, and the inner surface of the front plate-shaped portion 44P is superimposed on the outer surface of the adhesive piece-shaped portion 45P and glued and fixed, and the blank sheet P3 is folded into a flat shape so that it can be assembled into a box B3. In this case, first, as shown in Figure 16(1), the presser plate-shaped portion 51P is folded onto the inner surface of the adhesive piece-shaped portion 45P, and the left side of the inner surface of each presser plate fixing portion-shaped portion 512P, 513P, in this case, each presser plate fixing portion-shaped portion 512P, 513P, is bonded and fixed to the right side of the inner surface of each extension portion-shaped portion 452P, 453P, in this case, each extension portion-shaped portion 452P, 453P, via adhesive. Next, as shown in Figure 16(2), the adhesive piece-shaped section 45P to the bottom panel-shaped section 41P is folded along the fold line L41 between the bottom panel-shaped section 41P and the back panel-shaped section 42P, and folded between the inner surface of the back panel-shaped section 42P and the inner surface of the top panel-shaped section 43P. At the same time, the front panel-shaped section 44P is folded along the fold line L43 between the top panel-shaped section 43P and the front panel-shaped section 44P, and the front panel-shaped section 44P, in this case the upper and lower corners on the right side of the inner surface of the front panel-shaped section 44P, and the adhesive piece-shaped section 451P of the adhesive piece-shaped section 45P, in this case the upper and lower corners on the right side of the outer surface of the adhesive piece-shaped section 451P, are bonded and fixed via adhesive. Thus, the blank sheet P3 is folded into a flat shape so that the four side panel-shaped sections 41P-44P are connected and it can be assembled into a box B3. These flattened, unassembled B3 boxes are packed in cardboard and shipped to users such as pharmaceutical companies.

[0096] Figure 17 shows how 10 ampoules are packaged in box B3 by a pharmaceutical company, with the front panel 44 opened from the adhesive tab 45 of box B3. In this case, the 10 ampoules are stored in a londration (a shallow tray-type case with dividers) arranged in a single row, and this londration containing 10 ampoules is packaged inside box B3.

[0097] In the pharmaceutical packaging process at a pharmaceutical company, the box B3 is raised into a box shape before assembly, and a pack of 10 ampoules of Londoration is placed inside the box B3 through either the opening on the right or left end of the box B3. The opening on the right end is closed by the right end panel 46, the retaining plate fixing part 512 of the retaining plate 51 on the right end panel 46 side, and the extension part 452 of the adhesive piece 45, while the opening on the left end is closed by the left end panel 47, the retaining plate fixing part 513 of the retaining plate 51 on the left end panel 47 side, and the extension part 453 of the adhesive piece 45. When closing the opening at the right end of box B3, the flaps (461), 465, and 463 are folded in sequence to form the opening at the right end of box B3, and the outer surface of the large outer flap 463 and the outer surface of one of the smaller flaps 465 inside them are bonded and fixed with adhesive to the outer surface of the retaining plate fixing portion 512 of the retaining plate 51, which is superimposed and fixed to the inner surface of the extension portion 452 of the adhesive piece 45 on the right end plate 46 side. In this case, the extension portion 452 of the adhesive piece 45 becomes the outermost part. When closing the opening at the left end of box B3, the flaps (462), 466, and 464 are folded in sequence to form the opening at the left end of box B3, and the outer surface of the large outer flap 464 and the outer surface of one of the smaller flaps 466 inside them are bonded and fixed with adhesive to the outer surface of the retaining plate fixing portion 513 of the retaining plate 51, which is superimposed and fixed to the inner surface of the extension portion 453 of the adhesive piece 45 on the left end plate 47 side. In this case, the extension 453 of the adhesive piece 45 is on the outermost side. Thus, the 10 ampoules of londration are stored inside box B3, and the openings on the right and left ends of box B3 are sealed.

[0098] When the openings on the right and left ends of box B3 are closed in this manner, as shown in Figure 17(b), the retaining plate 51 curves outward from the inner surface of the adhesive piece 45 toward the opposing back plate 42, and each ampoule in the rondration is elastically held in place by this retaining plate 51.

[0099] In other words, when the openings at the right and left ends of box B3 are closed by the extensions 452 and 453 of the adhesive piece 45 and the pressing plate fixing parts 512 and 513 of the pressing plate 51, respectively, via the right end plate 46 and the left end plate 47, the pressing plate fixing parts 512 and 513 of the pressing plate 51, which are adhesively fixed to the inner surfaces of the extensions 452 and 453 of the adhesive piece 45, are rotated toward the openings at the right and left ends, with the folding lines (L55 and L56) between the pressing plate body 511 and the pressing plate fixing parts 512 and 513 as the pivot point. As a result, the pressing plate fixing parts 512 and 513 of the pressing plate 51 are folded along the folding lines (L55 and L56). These folds compress the inner surface of the presser plate 51 near each fold line (L55, L56), causing the main body portion 511 of the presser plate 51 between each fold line (L55, L56) to be compressed and deformed toward the left-right center of the presser plate 51, causing it to protrude in a convex, curved shape (circular arc in cross-section) toward the back panel 42 of the box B3. Each ampoule in the ionization container stored inside the box B3 is elastically held in place by this presser plate 51. Then, when the openings at the right and left ends are closed via the right end plate 46 and the left end plate 47, the fixing parts 512 and 513 of the retaining plate 51 and the extensions 452 and 453 of the connecting piece 45 are glued to the right end plate 46 and the left end plate 47, as described above, and the fixing parts 512 and 513 of the retaining plate 51 are glued to the right end plate 46 and the left end plate 47 at the openings at the right and left ends of box B3. Since the fixed parts 512, 513 and the respective extensions 452, 453 of the adhesive piece 45 are fixed, the curved deformation state of each presser plate body 511 is maintained within box B3 by the right end plate 46, the left end plate 47, the presser plate fixing parts 512, 513 of the presser plate 51 and the respective extensions 452, 453 of the adhesive piece 45. Within box B3, each ampoule in the rondration is pressed down by the presser plate 51 and held in place by the elastic action of the presser plate 51. Therefore, even if box B3 is subjected to an external impact, the 10 ampoules in the rondration will not rattle within box B3, and even if the 10 ampoules in box B3 are subjected to an external impact, this impact is absorbed by the elastic action of each presser plate 51, and the 10 ampoules are effectively protected within box B3.

[0100] In this packaging box B3, the front panel 44 has perforations 441 formed so that when the box B3 is assembled, the positions opposite the adhesive piece 45 of the front panel 44 and the notches 450 and 510 of the retaining plate 51 can be opened, and an opening lid 440 is provided. When opening this box B3, the opening lid 440 is cut open along the perforations 441 by pinching the tab 4401 and pulling it up from each cut 4411, and an opening is made in the front panel 44. In addition, in this box B3, zipper lines (431, 432) are formed on the fold lines L51 and L52 between the top panel 43 and the small flaps 465 and 466 on the left and right sides, so that the top panel 43 can be cut open together with the opening lid 440, and the opening lid 440 can be cut open from the front panel 44 to the top panel 43. In this way, box B3 is opened, and the ampoule can be easily and reliably removed from the opening formed between the retaining plate 51, the adhesive piece 45, and the top plate 43.

[0101] As explained above, this packaging box B3 is equipped with a cushioning function section 5 that can hold and secure multiple ampoules or drug packs inside the box. Therefore, even if a space equivalent to the gap for inserting the previous package insert is left inside the box B3, multiple ampoules or drug packs can be fixed inside the box B3. This eliminates the need to change the size of the box B3 and eliminates any other impacts that would result from changing the size of the box B3.

[0102] Furthermore, in this cushioning function section 5, the adhesive piece 45 consists of an adhesive portion 451 that is sized to fit within the surface of the front plate 44 on the other side of the four side plates 41-44, on one side edge of the bottom plate 41 on the adhesive side, and two extensions 452 and 453 that extend from both ends of this adhesive portion 451 and are sized to fit into the openings at both ends. The retaining plate 51 is formed symmetrically with the center of symmetry being a virtual straight line connecting the side edges opposite to the bottom plate 41 on each extension 452 and 453 of the adhesive piece 45, and on the inner surface of the adhesive piece 45 The box B3 is folded in, and each retaining plate fixing part 512, 513 is fixed to each extension part 452, 453. When the box B3 is assembled, the retaining plate 51 (retaining plate body part 511) is curved out on the inner surface of the adhesive piece 45, and this retaining plate 51 (retaining plate body part 511) is used to hold in place 10 ampoules or pharmaceutical packs. As a result, the cushioning function part 5 has an extremely simple structure, and the cushioning function part 5 can be provided in the box B3 without using a lot of box material or giving the box material a complex shape. Therefore, with this packaging box B3, it is possible to effectively protect the pharmaceuticals inside the box B3 while suppressing an increase in cost. In this case, groove-shaped notches 450 and 510 are provided on the mutually opposing side edges of the adhesive piece 45 and the retaining plate 51, and an opening lid 440 is provided on the front plate 44 at a position opposite to the notches 450 and 510 of the front plate 44 when the box B3 is assembled. As a result, multiple ampoules and pharmaceutical packs can be stably held inside the box B3, and the ampoules and pharmaceutical packs can be easily removed.

[0103] In the third embodiment, the retaining plate 51 is provided in a size that allows it to be positioned within the surface of the adhesive piece 45, connected to each side edge opposite to the bottom plate 41 by the extensions 452 and 453 of the adhesive piece 45. In this case, it is exemplified that the retaining plate 51 is formed symmetrically with a virtual straight line connecting the upper side edges as the center of symmetry, and groove-shaped notches 450 and 510 are symmetrically provided on the mutually opposing upper side edges of the adhesive piece 45 and the retaining plate 51. However, the retaining plate and the adhesive piece may be formed asymmetrically as long as the retaining plate can fit within the surface of the adhesive piece. An example of this is shown in Figure 18.

[0104] As shown in Figure 18, the retaining plate-shaped portion 51-1P is formed asymmetrically via fold lines L45 and L46 on each side edge opposite to the bottom plate-shaped portion 41P at each extension-shaped portion 452P and 453P of the adhesive piece-shaped portion 45P, i.e., each left edge. Groove-shaped notches 450 and 510-1 are provided on each mutually opposing side edge of the adhesive piece-shaped portion 45P and the retaining plate-shaped portion 51-1P. Here, the retaining plate-shaped portion 51-1P is connected via fold lines L45 and L46 to approximately half of each side edge that is away from the adhesive piece-shaped portion 451P at each of the upper and lower extension-shaped portions 452P and 453P of the adhesive piece-shaped portion 45P, i.e., each left edge, and is formed in a slightly smaller size and with a different outer shape than the adhesive piece-shaped portion 45P. In this case, as previously described, the adhesive piece shape portion 45P consists of an adhesive part shape portion 451P and extension part shape portions 452P and 453P at both the upper and lower ends. Therefore, the presser plate shape portion 51-1P consists of a presser plate body shape portion 511-1P that overlaps within the plate surface of the adhesive part shape portion 451P of the adhesive piece shape portion 45P, and two presser plate fixing part shape portions 512-1P and 513-1P that overlap within the plate surfaces of the respective extension part shape portions 452P and 453P of the adhesive piece shape portion 45P. In this case, the presser plate body shape portion 511-1P is originally formed as a vertically elongated rectangle with a width slightly smaller than the adhesive part shape portion 451P, and a notch portion 510-1 is formed along the side edge on the adhesive part shape portion 451 side in the shape of a rectangular groove that is vertically longer than the notch portion 450 of the adhesive piece shape portion 45P. Furthermore, the two extension-shaped parts 452P and 453P are formed in a roughly trapezoidal shape, slightly smaller than each opening, so as to be able to cover substantially the entire openings at the left and right ends of box B3 via fold lines L53 and L54 at both the upper and lower ends of the adhesive-shaped part 451P, and the two presser plate fixing-shaped parts 512-1P and 513-1P are formed in a rectangular shape, slightly shorter in length than the extension-shaped parts 452P and 453P and slightly smaller than each opening, so as to be able to cover substantially the entire openings at the left and right ends of box B3 via fold lines L55 and L56 at both the upper and lower ends of the presser plate body-shaped part 511-1P, and the length is slightly shorter than the length of each extension-shaped part 452P and 453P. In this way, the presser plate-shaped part 51-1P is formed in a roughly U-shape, slightly smaller in size than the adhesive piece-shaped part 45P as a whole.

[0105] Furthermore, with the formation of the pressing plate-shaped portion 51-1P in this manner, the two large flap-shaped portions 463P and 464P extend from the entire upper edge and the entire lower edge of the back plate-shaped portion 42P, respectively, and are formed in a roughly trapezoidal shape with roughly the same length as the upper and lower edges of the back plate-shaped portion 42P. In the pharmaceutical company's packaging process, adhesive (hot melt) is applied to the outer surfaces of the extension-shaped portions 452P and 453P of the adhesive piece-shaped portion 45P, so that the large flap-shaped portions 463P and 464P are bonded to these extension-shaped portions 452P and 453P. In this case, when closing the opening at the right end of box B3, the small flap-shaped parts 461P and 465P are folded over the opening at the right end of box B3. On top of that, the retaining plate fixing part 512-1P of the retaining plate-shaped part 51-1P, which is superimposed and fixed to the inner surface of the extension part 452P of the adhesive piece-shaped part 45P on the right end plate 46 side, is folded over together with the extension part 452P. Furthermore, the large flap-shaped part 463P on the right end plate 46 side is folded over and adhered and fixed to the outer surface of the extension part 452P with adhesive. In this case, the large flap-shaped part 463P is on the outermost side. The same procedure applies when closing the opening at the left end of box B3. The small flap-shaped sections 462P and 466P are folded over the opening at the left end of box B3. On top of these, the retaining plate fixing section 513-1P of the retaining plate-shaped section 51-1P, which is superimposed and fixed to the inner surface of the extension section 453P of the adhesive piece-shaped section 45P on the left end panel 47 side, is folded over together with the extension section 453.
