Description

[Technical Field]

[0001] The present invention relates to a packaging box with a shock-absorbing function used for packaging medicines and various other items. [Background technology]

[0002] Generally, medical drugs such as tablets and capsules handled by medical institutions and dispensing pharmacies are stored in a single PTP sheet, with multiple units of these PTP sheets then further packed in pillowcases or bundled together with cable ties and packaged in a packaging box (individual packaging box).

[0003] This type of packaging box, as disclosed in Patent Document 1, for example, comprises four side panels formed parallel to one another and defining a front, back, left side, and right side, an adhesive strip formed along one of the side edges of the panels, a top lid consisting of a pair of flaps and a lid, and a bottom lid forming the bottom, with the adhesive strips along one edge of the four side panels being glued to the other edge. In this process of packaging pharmaceuticals, the four side panels are folded into a rectangular prism shape, the pharmaceutical is placed inside, the bottom lid is folded and glued, and the top opening of the box is sealed with the lid, resulting in an overall assembly into a roughly rectangular parallelepiped shape. In this manner, the pharmaceutical is packaged.

[0004] Previously, prescription drugs of this type were accompanied by a package insert containing various information about the drug, such as the drug's name, dosage, efficacy, and handling precautions, and were packaged in a packaging box. This package insert was typically made of relatively large paper, such as A3 size, and folded into a long, thin shape to fit inside the box. This folded package insert was relatively thick. The package insert was then placed inside the box in its long, thin shape, sandwiching the drug between the two. This arrangement held the drug in place and protected it from external impacts. However, the November 2019 revision to the Pharmaceutical and Medical Device Act required package inserts to be provided electronically, which will come into effect in August 2021. This means that the attachment of package inserts to drugs will be abolished. Without the package insert included in the packaging box, the traditional box would naturally leave a gap inside the box to accommodate the package insert, reducing the drug's protective capabilities. For this reason, the previous box design needs to be changed. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 6-53425 Summary of the Invention [Problem to be solved by the invention]

[0006] The conventional packaging boxes (individual boxes) mentioned above can eliminate gaps inside the box if the size (dimensions) is reduced to match the overall size (dimensions) of the pharmaceutical product (a packaged pharmaceutical product in which multiple tablets or capsules are sealed in PTP sheets enclosed in aluminum packs). However, changing the size of this box not only requires adjustments to the settings of the cartoner (a machine that boxes items while simultaneously forming packages), but also requires changes to the sizes of the bulk boxes that hold multiple individual boxes, and the cardboard boxes that hold multiple bulk boxes. This means that the changes to the pharmaceutical packaging process are widespread, creating a significant burden.

[0007] Furthermore, many boxes of this type have been proposed that have a cushioning function inside the box to protect the medicines, but in many cases, in order to have the cushioning function part integrated inside the box, a lot of box material (paper material such as paperboard) is used or the box material (paper material such as paperboard) is given a complex shape, which results in a problem of increased costs compared to boxes without a cushioning function part.

[0008] The present invention solves these conventional problems by making it possible to fix pharmaceuticals inside a packaging box of this type, even if a space equivalent to the gap for inserting a conventional package insert is left inside the box, thereby eliminating the need to change the size of the box and eliminating the impact on other areas that would result from changing the size of the box, and by making the buffer functional part of an extremely simple structure so that it can be provided without using a lot of box material inside the box or giving the box material a complex shape, thereby effectively protecting the pharmaceuticals inside the box while suppressing increases in costs. [Means for solving the problem]

[0009] In order to achieve the above object, the present invention provides: a top cover that closes a top opening and a bottom cover that closes a bottom opening, the top opening and the bottom cover being made of a pair of flaps respectively connected to the edges of two of the four side panels that face each other, and a cover formed on the edge of one or two other side panels other than the two side panels; A buffer function part capable of pressing and holding an article is provided on the top opening side and / or the bottom opening side of the box, The buffer function portion is an extension plate extending from the other side edge of the adhesive piece opposite to one side edge of one end of the four side panels into the one side panel at the other end of the four side panels joined to the adhesive piece; and a presser flap extending in a flap shape so as to be able to protrude onto the top opening and / or the bottom opening via a fold line from a position of the extension plate lowered into the box relative to the edge of the top opening side and / or the bottom opening side of the four side panels, In the extension plate, the fold line is formed obliquely between a fold line start position at one side edge of the adhesive piece of the extension plate, which is lowered a predetermined distance into the box relative to the edge of the top opening side and / or the bottom opening side of the four side panels, and a fold line end position at the other side edge opposite to the one side edge of the adhesive piece of the extension plate, which is lowered a predetermined distance further into the box than the fold line start position, By assembling the box, the flaps on the top opening side and / or the bottom opening side press and tilt the pressing flaps below the top opening and / or the bottom opening, and the pressing flaps press and hold the articles. The gist of this is as follows.

[0010] This packaging box preferably also has the following features: (1) The fold line has a convex cut line formed inward of the box between the fold line start position and the fold line end position, and the pressure flap has a protrusion that protrudes and engages with one of the other end side panels of the four side panels joined to the adhesive strip when the pressure flap is pressed and tilted under the top opening and / or bottom opening of the box, pressing the extension panel toward the article. Also, a fold line is formed between the adhesive strip and the extension panel so that the extension panel can be tilted toward the article relative to the adhesive strip inside the box. (2) On the holding flap, on the edge of the top opening side and / or the bottom opening side of the four side panels of the holding flap In contrast At the corresponding position formed The presser flap has a fold line that guides the presser flap to tilt toward the outside of the top opening and / or the outside of the bottom opening. (3) The extension plate extends in any shape from almost the entire other side edge of the adhesive piece or from part of it. (4) The pressure flaps extend in any shape from a position on the extension plate that is lowered into the box relative to the edges of the top opening and / or bottom opening of the four side panels. (5) A cutout is provided on one of the side panels at the other end of the four side panels joined with the adhesive strip, and the cutout is used as an information tag that displays various information about medicines and other items. (6) The canopy and / or bottom cover comprises an inner cover extending from the edge of one of the two side panels and having an insert at its tip, and an outer cover extending from the edge of the other side panel and bonded onto the inner cover with an adhesive, and has a break line between the other side panel and the outer cover, the break line being a cut line in the other side panel that is cut into the outer cover side end of the other side panel in a substantially groove-shaped manner with any two points between both ends of the edge of the other side panel as the cut ends, and two cut lines in the outer cover that are continuous with the cut ends of the two points of the cut line in the other side panel and cut in a substantially L-shaped manner in a direction away from the cut line in the other side panel to each side edge of the outer cover adjacent to the edge of the other side panel, and the break lines A portion of the other side panel that is surrounded by the cut line of the other side panel and the edge of the other side panel is formed as a breakable portion that can be separated from the other side panel, and two portions of the outer lid that are surrounded by the two cut lines of the outer lid and the edge of the other side panel are formed so that they can stand up as tags by separating the outer lid from the other side panel along the cut lines of the outer lid following the separation of the breakable portion, and by separating the breakable portion of the other side panel together with the outer lid from the other side panel along the break lines, the outer lid is opened and at the same time each of the two portions of the outer lid stands up as a tag indicating that the box has been opened, and the top opening and / or bottom opening is resealed with the inner lid. (7) Of the four side panels, each side panel, extension panel including adhesive strips and pressure flaps, and each part of the top and bottom lid, which are arranged between the front and back panels of the box, have a linearly extending ruled line or cut, or a combination of these, in the middle of the width direction, and are provided with a crush disposal function part that can fold and guide each part of each side panel, extension panel including adhesive strips and pressure flaps, and each part of the top and bottom lid, which are arranged between the front and back panels, to fold the entire box flat. [Effects of the Invention]

[0011] The cushioning packaging box of the present invention, with its above-mentioned configuration, achieves the following unique and exceptional effects. Specifically, this packaging box is provided with a cushioning function part capable of holding and holding an article on the top opening side and / or bottom opening side of the box, so that pharmaceuticals can be secured in the box even if a space corresponding to the gap for inserting a package insert is left inside the box. This eliminates the need to change the size of the box, and eliminates the impact of changing the size of the box. Furthermore, this cushioning function part comprises an extension plate that extends from the other side edge of one end of the four side panels of the adhesive strip opposite to the one side edge on the one side panel side toward the other end of the one side panel of the four side panels joined to the adhesive strip, and a holding flap that extends in a flap-like manner from a position on the extension plate that is lowered into the box relative to the top opening side and / or bottom opening side edges of the four side panels, via a fold line, so as to be able to protrude above the top opening and / or bottom opening. The fold line in the extension plate is formed diagonally between a fold line start position at one side edge of the adhesive side of the extension plate, which is a predetermined distance down into the box relative to the edge of the top opening side and / or bottom opening side of the four side panels, and a fold line end position at the other side edge opposite to the one side edge of the adhesive side of the extension plate, which is a predetermined distance down into the box from the fold line start position. In this way, when the box is assembled, the flaps on the top opening side and / or the bottom opening side press down and tilt the pressure flaps below the top opening and / or the bottom opening, and these pressure flaps press down and hold the articles, so the buffer function part has an extremely simple structure and can be provided without using a lot of box material inside the box or giving the box material a complex shape. Therefore, with this packaging box, it is possible to effectively protect the medicines inside the box while suppressing increases in cost. [Brief explanation of the drawings]

[0013] Next, embodiments of the present invention will be described with reference to the drawings. Figures 1 and 2 show a first embodiment. Figure 1 shows the configuration of a packaging box B1 with a cushioning function, and Figure 2 shows the configuration of a blank sheet P1 before assembly of the packaging box B1. This box B1 is shown as an example for packaging a pharmaceutical pack (a pharmaceutical pack in which multiple tablets or capsules are stored in a single PTP sheet, and multiple PTP sheets are further pillow-packaged or bundled together with a cable tie; the same applies below).

[0014] As shown in Figures 1 and 2, the packaging box B1 with cushioning function (hereinafter, sometimes referred to as packaging box B1 or box B1) is made of so-called cardboard and is composed of four side panels (back panel 11, left panel 12, front panel 13, right panel 14) that are formed parallel to each other and form the front, back, left side, and right side of the box B1, an adhesive piece 15 formed in accordance with one side edge of one end of one of these four side panels, a pair of flaps formed in conjunction with the edge of two of the four side panels that face each other, and an outer lid and an inner lid formed on the edge of two other side panels other than the two side panels, a top lid 16 that closes the top opening, and a bottom lid 17 that closes the bottom opening.

[0015] In the case of box B1, rear panel 11 and front panel 13 are each vertically elongated rectangles of the same size, and left and right side panels 12 and 14 are each vertically elongated rectangles of the same size but narrower than rear panel 11 and front panel 13. Adhesive strip 15 has a width that is about one-third of the width of each of the left and right side panels 12 and 14, and in this case extends in a roughly trapezoidal shape from the right edge of rear panel 11. This adhesive strip 15 is connected to the rear surface of right side panel 14, at the edge on the rear panel 11 side, via glue.

[0016] In the case of this box B1, the canopy 16 is composed of an approximately trapezoidal outer lid 161 that is connected to each edge of the four side panels 11-14, in this case the upper edge of the back panel 11, via fold line L5 and is capable of covering the entire top opening 10U, an approximately trapezoidal inner lid 162 that is connected to the upper edge of the front panel 13 via fold line L7 and is capable of covering a portion of the top opening 10U (approximately four-fifths or three-quarters of the entire top opening 10U), and a pair of approximately trapezoidal left and right flaps 163, 164 that are connected to the upper edges of each of the left and right side panels 12, 14 via fold lines L6, L8 and are capable of partially covering the top opening 10U (approximately two-fifths of the entire top opening 10U), and the top opening 10U is closed sequentially by the inner lid 162 and outer lid 161 via the left and right flaps 163, 164, and is sealed by gluing the outer lid 161 to the inner lid 162. In addition, each of the fold lines L5-L8 on the four side panels is formed by a concave line extending from the front side to the back side of the box B1 on the upper edge of each of the four side panels, allowing each part of the canopy 16 to be tilted and guided outward from the top opening 10U.

[0017] In the case of this box B1, the bottom lid 17 is composed of a roughly trapezoidal outer lid 171 that is connected to each edge of the four side panels 11-14, in this case the lower edge of the back panel 11, via fold line L9 and is capable of covering the entire bottom opening 10D, a roughly trapezoidal inner lid 172 that is connected to the lower edge of the front panel 13 via fold line L11 and is capable of covering a portion of the bottom opening 10D (approximately four-fifths or three-quarters of the entire bottom opening 10D), and a pair of roughly trapezoidal left and right flaps 173, 174 that are connected to the lower edges of each of the left and right side panels 12, 14 via fold lines L10, L12 and are capable of partially covering the bottom opening 10D (approximately two-fifths of the entire bottom opening 10D), and the bottom opening 10D is closed sequentially by the inner lid 172 and outer lid 171 via each flap 173, 174, and is sealed by gluing the outer lid 171 to the inner lid 172. In addition, each of the fold lines L9-L12 on the four side panels is formed by a linear concave line extending from the front side to the back side of the box B1 on the lower edge of each of the four side panels, allowing each part of the bottom cover 17 to be tilted and guided outward from the bottom opening 10D.

[0018] In addition, in this box B1, tear lines C1 and C2 for opening are formed on the fold line L7 between the inner lid 162 of the canopy 16 and the front panel 13 to which the inner lid 162 is connected, and on the fold line L11 between the inner lid 172 of the bottom lid 17 and the front panel 13 to which the inner lid 172 is connected. In this case, the tear line C1 for opening on the canopy 16 side is formed by drawing a perforation line c1 in a substantially trapezoidal groove shape from the fold line L7 directly below the center of the fold line L7 between the inner lid 162 and the front panel 13, and further drawing 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 portion of the upper part of the front panel 13 surrounded by the groove-shaped perforation line c1 is hereinafter referred to as the opening opening T1. In this case, the tear line C2 for opening on the bottom lid 17 side is formed by drawing a perforation line c1 in a substantially trapezoidal groove shape from the fold line L11 directly above the center of the fold line L11 between the inner lid 172 and the front panel 13, and further drawing perforation lines c2 on the fold line L11 from both ends of the groove-shaped perforation line c1 to both ends of the fold line L11. Hereinafter, the portion surrounded by the groove-shaped perforations c1 at the bottom of the front panel 13 will be referred to as the opening opening T2.

[0019] In this way, the adhesive piece 15 at one end of the four side panels is joined to one side panel at the other end of the four side panels, in this case the right side panel 14, and by closing the bottom opening 10D with parts of the bottom cover 17 and closing the top opening 10U with parts of the top cover 16, the whole is assembled into a roughly rectangular box B1 for packaging pharmaceuticals.

[0020] Box B1 is provided with buffer functional sections 2 capable of pressing and holding medicine packs on the top opening 10U side and the bottom opening 10D side within box B1. These buffer functional sections 2 each include an extension plate 21 that extends from the other side edge of one end of one of the four side panels of adhesive piece 15 opposite to one side edge on that side of the one side panel, into the other end of the one side panel of the four side panels joined to adhesive piece 15, and two pressing flaps 22 that extend in a flap-like manner from a position on extension plate 21 lowered into box B1 (inward of box B1) relative to the edges of the four side panels on the top opening 10U side and the bottom opening 10D side, via fold line L13, so as to be able to protrude above top opening 10U and bottom opening 10D. The extension plate 21 extends in any shape from almost the entire other side edge of the adhesive piece 15, and each pressing flap 22 extends in any shape from a position on the extension plate 21 lowered inside the box B1 relative to the edges of the top opening 10U and bottom opening 10D of the four side panels.

[0021] In this case, one side edge of adhesive piece 15 on one side panel side at one end of one of the four side panels is the base end edge of adhesive piece 15 on the back panel 11 side, and the other side edge on the opposite side is the tip edge of adhesive piece 15, and the side panel at the other end of the four side panels joined to adhesive piece 15 is the right side panel 14. Extension panel 21 is provided as an integral plate together with two presser flaps 22 at the tip edge of adhesive piece 15, within the plane (range) of right side panel 14. This integral plate is formed into a vertically elongated rectangular shape overall, with a width (left-right dimension) of about two-thirds the width (left-right dimension) of each of the left and right side panels 12, 14 from the entire edge of the tip edge of adhesive piece 15, and a length (vertical dimension) approximately the same as the length (vertical dimension) of each of the left and right side panels 12, 14. In this case, the extension plate 21 is a generally trapezoidal portion of the integrated plate located inside each fold line L13 (described later), and the two presser flaps 22 are generally rectangular portions of the integrated plate extending outside each fold line L13 (described later). The corner of the tip of each presser flap 22 on the back panel 11 side is cut off diagonally in a straight line, and the corner on the opposite side is cut off in an arc shape.

[0022] In this buffer function part 2, the fold line L13 in the extension plate 21 is formed diagonally between a fold line start position a1, which is located at one side edge of the extension plate 21 on the adhesive piece 15 side and slightly lower by a predetermined distance into the box B1 relative to the edges of the top opening 10U and bottom opening 10D sides of the four side panels, and a fold line end position a2, which is located at the other side edge opposite the one side edge of the extension plate 21 on the adhesive piece 15 side and is further lower by a predetermined distance into the box B1 than the fold line start position a1.

[0023] In this case, one side edge of extension plate 21 on the adhesive strip 15 side is the edge of back panel 11 of extension plate 21, the edges of the top and bottom opening sides of the four side panels of extension plate 21 are the upper and lower edges of extension plate 21, and the other side edge opposite the one side edge of extension plate 21 on adhesive strip 15 side is the edge of front panel 13 of extension plate 21, and fold line L13 is formed diagonally between fold line start position a1, which is a predetermined distance slightly lower inward from the upper and lower edges of extension plate 21, at the edge of back panel 11 of extension plate 21, and fold line end position a2, which is a predetermined distance slightly lower inward from fold line start position a1 at the edge of front panel 13 of extension plate 21. In this case, fold line L13 is formed by a perforation line.

[0024] In addition, in this buffer function section 2, the pressure flap 22 has a fold line L14 at a position corresponding to the edge of the top opening 10U side and the bottom opening 10D side of the four side panels, which guides the pressure flap 22 to tilt toward the outside of the top opening 10U and the outside of the bottom opening 10D.

[0025] In this case, each fold line L14 on these pressure flaps 22 is formed by a concave line extending from the front side to the back side of the box B1 at a position corresponding to each of the upper and lower edges of the four side panels, so that these pressure flaps 22 can be tilted and guided toward the outside of the top opening 10U and the outside of the bottom opening 10D.

[0026] The box B1 is made of a blank sheet P1 formed integrally by punching out a paperboard together with each of the buffer functional sections 2. As shown in FIG. 2, the blank sheet P1 has the following structure.

[0027] At one end, a back plate shape portion 11P is formed as a vertically elongated rectangle of a predetermined size that forms the back plate 11 of box B1, and on one long side to the right of this back plate shape portion 11P, a left side plate shape portion 12P that is a rectangle the same length (height) as back plate shape portion P11 but slightly smaller in width and forms the left side plate 12 of box B1, a front plate shape portion 13P that has the same size and shape as back plate shape portion 11P and forms the front plate 13 of box B1, and a right side plate shape portion 14P that has the same size and shape as left side plate shape portion 12P and forms the right side plate 14 of box B1 are formed successively along fold lines L1, L2, and L3. Then, on the other long side of the left side of back plate shape portion 11P, a vertically elongated band-shaped adhesive piece 15P, in this case a trapezoid with the other long side on the left side as its base, is formed continuously along fold line L4. Each fold line L1-4 is formed by a concave ruled line extending from the front side to the back side of the blank sheet P1. The back plate shape portion 11P, left side plate shape portion 12P, front plate shape portion 13P, and right side plate shape portion 14P, each including an adhesive piece shape portion 15P, form four side plates.

[0028] An outer lid portion 161P, which is a trapezoidal outer lid portion having approximately the same size as the top opening 10U and which forms the outer lid 161, is formed continuously along a fold line L5 on one upper short side of the back panel portion 11P. A flap portion 163P, which is a trapezoidal left-side flap 163 slightly shorter than half the length of the outer lid portion 161P, is formed continuously along a fold line L6 on one upper short side of the left panel portion 12P. An inner lid portion 162P, which is a trapezoidal inner lid portion having a length shorter than the outer lid portion 161P and which forms the inner lid 162, is formed continuously along a fold line L7 on one upper short side of the front panel portion 13P. A flap portion 164P, which is a trapezoidal right-side flap 164 having approximately the same size as the flap portion 163P, is formed continuously along a fold line L8 on one upper short side of the right panel portion 14P. Each of the fold lines L5-L8 is formed by a concave ruled line extending from the front side to the back side of the blank sheet P1. The canopy 16 is formed by the outer lid-shaped portion 161P, the inner lid-shaped portion 162P, and the left and right flap-shaped portions 163P and 164P.

[0029] An outer lid portion 171P, which is a trapezoidal outer lid portion having approximately the same size as the bottom opening 10D and which forms the outer lid 171, is formed continuously along a fold line L9 on one lower short side of the back panel portion 11P. A flap portion 173P, which is a trapezoidal left-side flap 173 slightly shorter than half the length of the outer lid portion 171P, is formed continuously along a fold line L10 on one lower short side of the left panel portion 12P. An inner lid portion 172P, which is a trapezoidal inner lid portion having a length shorter than the outer lid portion 171P and which forms the inner lid 172, is formed continuously along a fold line L11 on one lower short side of the front panel portion 13. A lower flap portion 174P, which is a trapezoidal right-side flap 174 having approximately the same size as the flap portion 173P, is formed continuously along a fold line L12 on one lower short side of the right panel portion 14P. Each of the fold lines L9-L12 is formed as a concave ruled line extending from the front side to the back side of the blank sheet P1. The bottom lid 17 is formed by the outer lid shape portion 171P, the inner lid shape portion 172P, and the left and right flap shape portions 173P and 174P.

[0030] An extension plate-shaped portion 21P forming an extension plate 21 is formed on the adhesive piece-shaped portion 15P, and two presser flap-shaped portions 22P forming two presser flaps 22 are formed on this extension plate-shaped portion 21P. In this case, the extension plate-shaped portion 21P, together with the two presser flap-shaped portions 22P, is continuous with one long side on the left side of the adhesive piece-shaped portion 15P, and is provided so that the extension plate-shaped portion 21P can be arranged within (within) the plate surface of the right side plate-shaped portion 14P, and each presser flap-shaped portion 22P can protrude vertically from each of the upper and lower short sides of the right side plate-shaped portion 14P to the same height as each of the left and right flap-shaped portions 163P, 164P, 173P, 174P. Here, the integrated shape portions of the extension plate-shaped portion 21P and the two pressing flap-shaped portions 22P are continuous with one of the long sides on the left side of the adhesive piece-shaped portion 15P, and have a width (left-right dimension) that is about two-thirds of the width (left-right dimension) of each of the left and right side plate-shaped portions 12P, 14P, and a length (vertical dimension) that is approximately the same as the length (vertical dimension) of each of the left and right side plate-shaped portions 12P, 14P, so that overall they are formed into a vertically elongated rectangle. In this integral portion, a fold line start position a1 is set on one long side of the right side a predetermined distance toward each of the left and right side panel portions 12P, 14P relative to the upper and lower short sides of the four side panels, and a fold line end position a2 is set on the other long side of the left side a predetermined distance toward each of the left and right side panels 12P, 14P from the fold line start position a1, and fold lines L13 are formed obliquely between these fold line start position a1 and fold line end position a2 by perforations. Thus, in this integral portion, extension plate portion 21P consists of a substantially trapezoidal portion located inside each fold line L13, and two presser flap portions 22P each consist of a substantially rectangular portion extending outside each fold line L13 in the integral portion. Each corner of the protruding end of each pressure flap portion 22P is cut off diagonally in a straight line on the back panel portion 11P side, and cut off in an arc on the opposite side. Furthermore, in each pressure flap portion 22P, a fold line L14 is formed in a straight line from the front side to the back side of the blank sheet P1 at a position corresponding to each of the upper and lower short sides of the four side panels. This integrated portion forms the buffer function portion 2.

[0031] The blank sheet P1 is aligned with the side edge of the back surface portion 11P on the front side of the adhesive piece portion 15P and the back side of the right side panel portion 14P, and is glued together, and then folded into a flat shape so that it can be assembled into a box B1. This flat unassembled box B1 is packed in cardboard or the like and shipped to a user such as a pharmaceutical company.

[0032] Thus, by assembling this box B1, the flaps 164, 174 on the top opening 10U side and the bottom opening 10D side press down and tilt the pressure flaps 22 below the top opening 10U and the bottom opening 10D, and these pressure flaps 22 press down and hold the pharmaceutical packs.

[0033] FIG. 3 shows the state in which a pharmaceutical pack is packaged in a box B1 at a pharmaceutical company, with the front panel 13 of the box B1 removed.

[0034] In the pharmaceutical packaging process at a pharmaceutical company, an unassembled box B1 is erected into a box shape, and either top opening 10U or bottom opening 10D of box B1 is closed with a top cover 16 or bottom cover 17, and a drug pack is placed inside box B1 from the other open opening. Then, once the drug pack is placed inside box B1, the other of top opening 10U or bottom opening 10D of box B1, i.e., the other open opening, is closed with top cover 16 or bottom cover 17.

[0035] When the top opening 10U and the bottom opening 10D are closed by the top cover 16 and the bottom cover 17, the flaps 164, 174 on the top opening 10U side and the bottom opening 10D side press down and tilt the pressure flaps 22 on the top opening 10U side and the bottom opening 10D side downwards to the top opening 10U and the bottom opening 10D side, and the medicine pack is held down by these pressure flaps 22.

[0036] That is, when top opening 10U and bottom opening 10D are closed by top lid 16 and bottom cover 17, first, upper and lower flaps 163, 164 and flaps 173, 174 are folded at approximately right angles to top opening 10U and bottom opening 10D of box B1 relative to left and right side panels 12, 14. At this time, right flaps 164, 174 come into contact with upper and lower pressing flaps 22 extending from extension panel 21 onto top opening 10U and bottom opening 10D via fold line L13, and the inner surface of the upper right flap 164 presses the upper pressing flap 22 toward top opening 10U, and the inner surface of the lower right flap 174 presses the upper pressing flap 22 toward bottom opening 10D. The upper right flap 164 and the lower right flap 174 are tilted down to the surface of the top opening 10U and the surface of the bottom opening 10D, respectively, and the upper and lower presser flaps 22 are pressed down and tilted directly below the top opening 10U (directly below the surface of the top opening 10U) and directly below the bottom opening 10D (directly below the surface of the bottom opening 10D) with each fold line L13 of the extension plate 21 as a fulcrum. In this case, the fold line L13 that serves as the fulcrum for the upper presser flap 22 extends diagonally upward from the front panel 13 side toward the back panel 11 side of the box B1, so that the edge of the upper presser flap 22 on the side of the left side panel 12 of the box B1 extends diagonally slightly toward the back panel 11 side relative to the left side panel 12 of the box B1, and the plate surface of this presser flap 22 is inclined so that the edge on the front panel 13 side of the box B1 faces diagonally downward and the edge on the back panel 11 side of the box B1 faces diagonally upward. In contrast, fold line L13, which serves as a fulcrum for lower pressure flap 22, extends diagonally downward from the front panel 13 side toward the back panel 11 side of box B1, so that the edge of lower pressure flap 22 on the left side panel 12 side of box B1 extends slightly diagonally toward the back panel 11 side relative to the left side panel 12 of box B1, and the plate surface of this pressure flap 22 is inclined so that the edge on the front panel 13 side of box B1 faces diagonally upward, and the edge on the back panel 11 side of box B1 faces diagonally downward. These two surfaces of pressure flaps 22 press down the medicine packs in box B1 as if embracing or pulling them from above the corners between the top and right side surfaces and the corners between the bottom and right side surfaces, and the medicine packs are held in place between these pressure flaps 22 and the left side panel 12 of box B1.Then, the inner lid 162, outer lid 161, inner lid 172, and outer lid 171 are sequentially folded onto the top opening 10U and bottom opening 10D of box B1 from above the flaps 163, 164 and flaps 173, 174, and the outer lid 161 is adhered to the inner lid 162, and the outer lid 171 is adhered to the inner lid 172 with glue. This fixes the top lid 16 and bottom lid 17 to the top opening 10U and bottom opening 10D of box B1, and the top lid 16 and bottom lid 17 maintain the tilted state of each presser flap 22 within box B1, and the presser flaps 22 press down on the medicine packs within box B1 as if embracing or pulling them together as described above, and the presser flaps 22 press down and hold them in place due to the elastic action of each presser flap 22. Therefore, even if the box B1 receives an external impact, the medicine packs inside the box B1 will not rattle, and even if an impact is received by the medicine packs inside the box B1, the impact is absorbed by the elastic action of each pressing flap 22, and the medicine packs inside the box B1 are effectively protected.

[0037] In addition, this packaging box B1 has a trapezoidal perforation line C1 formed downward from fold line L7 at the top of the front panel 13. When opening the box B1, the top lid 16 can be opened by pressing and breaking the opening T1 surrounded by this breaking line C1. The top opening 10U of the box B1 can be opened by pressing a finger against the opening T1, which is separated from the top of the front panel 13 during this opening, and pulling the outer lid 161 together with the inner lid 162 upward. In addition, a trapezoidal perforation line C2 formed upward from fold line L11 at the bottom of the front panel 13. When disposing of the box B1, the bottom lid 17 can be opened by pressing and breaking the opening T2 surrounded by this breaking line C2, making it easier to disassemble the box B1. By pressing a finger against the opening T2, which is separated from the lower part of the front panel 13 by opening the bottom lid 17, and pulling down the outer lid 171 together with the inner lid 172, the bottom opening 10D of the box B1 can be opened, and the box B1 can be easily folded.

[0038] As described above, this packaging box B1 is provided with buffer functional sections 2 on the top opening 10U side and the bottom opening 10D side inside box B1 that can press and hold the pharmaceutical packs, so that the pharmaceutical packs can be securely fixed inside box B1 even if a space corresponding to the gap for inserting the previous package insert is left inside box B1. This eliminates the need to change the size of box B1, and eliminates other impacts that would result from changing the size of box B1, such as the need to adjust the settings of the cartoner and the need to change the size of the bulk box that contains multiple individual packaging boxes and the cardboard box that contains multiple bulk boxes, which would require extensive changes and a heavy burden in the pharmaceutical packaging process.

[0039] In addition, this buffer function part 2 is composed of an extension plate 21 that extends from the other side edge opposite to the one side edge on the back panel 11 side of the adhesive piece 15, i.e., from the tip edge, into the right side panel 14 that is joined to the adhesive piece 15, and each pressing flap 22 that extends in a flap-like manner from a position on the extension plate 21 that is lowered into the box B1 relative to the edge of the top opening 10U side and the bottom opening 10D side of the four side panels, via fold line L13, so as to be able to protrude above the top opening 10U and the bottom opening 10D. In this way, by assembling the box B1, the flaps 164, 174 on the top opening 10U side and the bottom opening 10D side press down and tilt the pressure flaps 22 below the top opening 10U and the bottom opening 10D, and these pressure flaps 22 press down and hold the medicine packs, so the buffer function section 2 has an extremely simple structure and can be provided without using a lot of box material inside the box B1 or giving the box material a complex shape. Therefore, with this packaging box B1, it is possible to effectively protect the medicine packs inside the box B1 while suppressing increases in costs.

[0040] Furthermore, this buffer function section 2 has the following advantages. (1) Each pressure flap 22 has fold lines L14 at positions corresponding to the edges of the top opening 10U and bottom opening 10D of the four side panels, which guide the pressure flap 22 to tilt outward from the top opening 10U and bottom opening 10D. Therefore, during the pharmaceutical packaging process at a pharmaceutical company, when the boxes are assembled using a cartoner and pharmaceutical packs are packed into boxes, each pressure flap 22, along with each part of the top cover 16 and bottom cover 17, can be easily opened outward from the top opening 10U and bottom opening 10D, allowing the pharmaceutical packs to be packed smoothly. (2) The extension plate 21 extends in any shape from substantially the entire other side edge (tip edge) of the adhesive piece 15. In other words, the shape of the extension plate 21 is not particularly limited and can be changed as desired depending on the shape and size of the box B1. Similarly, each of the pressure flaps 22 extends in any shape from a position lowered into the box B1 relative to the edges of the four side panels on the top opening 10U side and the bottom opening 10D side. In other words, the shape of each pressure flap 22 is not particularly limited and can be changed as desired depending on the shape and size of the box B1. In particular, the extension plate 21 and each pressure flap 22 may have a simple shape and are formed integrally with part of the box B1, thereby keeping manufacturing costs low.

[0041] 4 and 5 show a second embodiment. FIG. 4 shows the configuration of a packaging box B2 with a cushioning function, and FIG. 5 shows the configuration of a blank sheet P2 before assembly of the packaging box B2. This packaging box B2 has a configuration that is generally the same as that of the first embodiment, but has a configuration that is different from that of the first embodiment in part of the cushioning function section 2. Therefore, in the description of this embodiment, the configuration that is the same as that of the first embodiment will be given the same reference numerals and redundant description will be omitted, and the differences from the first embodiment will be given new reference numerals and described.

[0042] In this packaging box B2, a cut line C3 having a convex cut C32 facing inward of the box B2 is formed on each fold line L13 in the extension plate 21 between the fold line start position a1 and the fold line end position a2, and each of the upper and lower pressure flaps 22 has a protrusion 221 that protrudes and engages with one of the other ends of the four side panels joined with the adhesive piece 15 when these pressure flaps 22 are pressed and tilted below the top opening 10U and the bottom opening 10D of the box B2, pressing the extension plate 21 against the pharmaceutical pack.

[0043] In this case, as already described, the fold line L13 is formed diagonally between a fold line start position a1 at the edge of the back panel 11 of the extension plate 21, which is a predetermined distance slightly lower toward the inside of the box B2 relative to the upper and lower edges of the adhesive piece 15, and a fold line end position a2 at the edge of the front panel 13 of the extension plate 21, which is a predetermined distance slightly lower toward the inside of the box B2 than the fold line start position a1.

[0044] In this case, the shape of the middle portion of the fold line L13 is different from that of the first embodiment. In the first embodiment, the fold line L13 was formed diagonally in a straight line overall. However, in this embodiment, the fold line L13 has both ends formed by linear notches C31, and the middle portion formed by a convex notch C32 that extends into the plate surface of the extension plate 21. In the case of the upper fold line L13, the convex notch C32 consists of a notch extending in a generally L-shape from the end of the left-end notch C31 through the connecting portion, and a notch extending diagonally from this notch to the end of the right-end notch C31. In the case of the lower fold line L13, the convex notch C32 is vertically symmetrical to the upper fold line L13, and consists of a notch extending in a generally L-shape from the end of the left-end notch C31 through the connecting portion, and a notch extending diagonally from this notch to the end of the right-end notch C31. As a result, the upper and lower protrusions 221 have a shape similar to the cutting edge of a cutter commonly used in office supplies. Furthermore, in this case, a fold line L14 consisting of a cut line is provided between the adhesive piece 15 and the extension plate 21 so that the extension plate 21 can be tilted toward the medicine relative to the adhesive piece 15 inside the box B2.

[0045] 6, when the top opening 10U and the bottom opening 10D are closed by the top lid 16 and the bottom lid 17, the flaps 164, 174 on the top opening 10U side and the bottom opening 10D side press down and tilt the pressure flaps 22 on the top opening 10U side and the bottom opening 10D side downwards, respectively, and the protrusions 221 of the pressure flaps 22 protrude and engage with one side panel at the other end of the four side panels, in this case the right side panel 14, pressing the extension plate 21 against the medicine packs. The extension plate 21 presses down the medicine packs from above on the right side, and the upper and lower pressure flaps 22 press down and hold the upper and lower corners of the medicine packs, pressing the medicine packs against the left side panel 12 of box B2 and sandwiching them between the extension plate 21 and the left side panel 12 of box B2.

[0046] In this way, in addition to the same effect as in the first embodiment, the extension plate 21 presses the medicine packs from above on the right side and holds them down between the left side panel 12 of box B2. Therefore, the extension plate 21, along with the two surfaces of the upper and lower pressure flaps 22, presses down on the medicine packs in box B2 by three sides, hugging or embracing them at the corners between the top and right side, the corners between the bottom and right side, and from above on the right side. The medicine packs are sandwiched and held between the pressure flaps 22 and the extension plate 21 and the left side panel 12 of box B2. This more firmly holds down and holds the medicine packs in box B2. Therefore, even if box B2 receives an external impact, the medicine packs inside box B2 will not rattle as much. Furthermore, even if the medicine packs inside box B2 receive an impact, the impact is more effectively absorbed by the elasticity of the pressure flaps 22, so that the medicines inside box B2 are more effectively protected.

[0047] Therefore, according to this packaging box B2, the effects of the first embodiment can be further improved.

[0048] Figure 7 shows the third embodiment. Figure 7 shows the configuration of the blank sheet P3 before assembly of the cushioning packaging box B3. This packaging box B3 has a configuration generally common to the first embodiment, but also has an opened display function, a resealing function, and a crush disposal function. The addition of these functions results in the bottom lid, top cover, and some of the four side panels having configurations different from those of the first embodiment. Therefore, in the description of this embodiment, the configurations common to the first embodiment will be assigned the same reference numerals and redundant explanations will be omitted, and differences from the first embodiment will be assigned new reference numerals and explained.

[0049] As shown in FIG. 7 , in this packaging box B3, the top cover 18 is composed of an inner cover 181 connected to the upper edge of the back panel 11 via crease L5, an outer cover 182 connected to the upper edge of the front panel 13 via crease L7, and a pair of left and right flaps 183, 184 connected to the upper edges of the left and right side panels 12, 14 via crease L6, L8. In this case, the inner cover 181 is formed as a whole rectangular so as to be able to cover almost the entire top opening 10U of the box B3, and an insertion piece 1811 protrudes from its upper end (tip). The outer cover 182 is formed as a whole trapezoid so as to be able to cover almost the entire top opening 10U of the box B3. The left and right flaps 183, 184 are formed as a whole protruding in an approximately M-shape so as to be able to partially cover (both the left and right ends of) the top opening 10U of the box B3, and as part of the crush disposal function section 5, have V-shaped leading edges. An opened display function section 3A is attached to the four side panels and part of the canopy 18 of this box B3, a resealing function section 4 is provided on the canopy 18, and a crush disposal function section 5 is provided on the canopy 18 and part of the four side panels.

[0050] The bottom lid 19 comprises an inner lid 191 connected to the lower edge of the back panel 11 via crease L9, an outer lid 192 connected to the lower edge of the front panel 13 via crease L11, and a pair of left and right flaps 193, 194 connected to the lower edges of the left and right side panels 12, 14 via crease L10, L12. In this case, the inner lid 191 is formed generally in a roughly T-shape so as to be able to cover approximately half of the bottom opening 10D of the box B3 and as part of the crush disposal function section 5, with the width of the lower half (tip) being narrower. The outer lid 192 is formed generally in a trapezoidal shape so as to be able to cover approximately the entire bottom opening 10U of the box B3. The left and right flaps 193, 194, like the left and right flaps 183, 184 on the canopy 18 side, are capable of partially covering (both the left and right ends of) the bottom opening 10D of the box B3, and as part of the crushed waste functional part 5, are formed to protrude in a generally M shape with a V-shaped leading edge. The crushed waste functional part 5 is provided on the bottom lid 19 of this box B3.

[0051] In this packaging box B3, bottom opening 10D is closed by inner lid 191 and outer lid 192 via left and right flaps 193 and 194, and outer lid 192 is glued and sealed to inner lid 191, and top opening 10U is closed by inner lid 181 and outer lid 182 via left and right flaps 183 and 184, and insertion piece 1811 at the tip of inner lid 181 is glued to the end of the inside of front panel 13 on the canopy 18 side, and outer lid 182 is glued and sealed to inner lid 181. In this way, canopy 18 can be opened by cutting it along opening break line C10 formed on the top of front panel 13.

[0052] In this packaging box B3, the canopy 18 is composed of an inner lid 181 that extends from the edge of one of the two side panels, in this case the back panel 11, and has an insertion piece 1811 at its tip, and an outer lid 182 that extends from the edge of the other side panel, in this case the front panel 13, and is adhered onto the inner lid 181 with an adhesive, and is also provided with an opened display function unit 3A and a reseal function unit 4. A break line C10 is provided between the front panel 13 and the outer lid 182. This fracture line C10 consists of a cut line C101 on the front panel 13, which is cut into an approximately groove-shaped shape at the end of the front panel 13 facing the outer lid 18, with any two points between the two ends of the edge of the front panel 13 as the cut ends, and two cut lines C102 on the outer lid 182, which are cut into an approximately L-shaped shape in the outer lid 182, continuing from the two cut ends of the cut line C31 on the front panel 13 and extending in a direction away from the cut line C31 on the front panel 13 to each side edge of the outer lid 182 adjacent to the edge of the front panel 13. This break line C10 forms a part of the front plate 13 surrounded by the cut line C101 of the front plate 13 and the edge of the front plate 13 as a break portion C11 that can be separated from the front plate 13, and two parts of the outer lid 182 surrounded by the two cut lines C102 of the outer lid 182 and the edge of the front plate 13 are formed so that they can stand up as tags C12 by separating the outer lid 182 from the front plate 13 along each cut line C102 of the outer lid 182 following the separation of the break portion C11. In this way, by separating the break portion C11 of the front panel 13 along the break line C10 together with the outer lid 182 from the front panel 13, the canopy 18 is opened and at the same time, each of the two parts of the outer lid 182 stands up as a tag C12 (opened display function part 3A) indicating that the box B3 has been opened, and the top opening 10U is resealed by the inner lid 181 with the insertion piece 1811 (resealing function part 4).

[0053] In this way, when a medical institution opens packaging box B3 to use the pharmaceuticals contained in the packaging box B3, the rupture portion C11 of the front panel 13 together with the outer lid 182 is separated from the front panel 13 along the rupture line C10 (the cut line C101 of the front panel 13 and the cut line C102 of the outer lid 182), thereby opening the lid 18. At the same time, one corner on each side of the outer lid 182 is raised as a tag C12 indicating that the box B3 has been opened, thereby indicating that the box B3 has been opened. Then, the outer lid 182, the inner lid 181, and the left and right flaps 183, 184 of the lid 18 of the box B3 are sequentially opened, and the pharmaceuticals are removed. Then, the left and right flaps 183, 184, the inner lid 181, and the outer lid 182 are sequentially closed again, and the insertion piece 1811 of the inner lid 181 is inserted inside the front panel 13, thereby resealing the box B3. Even after resealing, the tags C12 indicating that the box B3 has been opened remain standing on the left and right corners of the outer lid 182, so that the box B3 continues to indicate that it has been opened, and these tags C12 make it easy to distinguish it from an unopened box.

[0054] This packaging box B3 has a cutout C41 on one side of the other end of the four side panels to be joined with the adhesive strip 15.

[0055] In this packaging box B3, a cut line C4 (in this case, a zipper line) is formed in the vertically middle portion of the right side panel 14 in the shape of a rectangular frame that is long in the vertical direction, forming a vertically long rectangular cutout portion C41. A convex tab portion C42 is also provided at the bottom end of this cutout portion C41. This cutout portion C41 can be separated from the right side panel 14 by pinching the tab portion C42 and pulling it upward. In this case, this cutout portion C41 serves as an information tag that displays various information about the medicines to be stored in this box B3.

[0056] This packaging box B3 is provided with a crush disposal function section 5 consisting of a linearly extending ruled line or cut or a combination thereof in the middle of the width direction of each of the side panels 12, 14, the extension panel 21 including the adhesive piece 15 and each of the pressing flaps 22, the top lid 18 and the bottom lid 19, which are arranged between the back panel 11 and the front panel 13 out of the four side panels of the box B3, and which can be folded and guided to fold and guide each of the side panels 12, 14, the extension panel 21 including the adhesive piece 15 and each of the pressing flaps 22, the top lid 18 and the bottom lid 19, which are arranged between the back panel 11 and the front panel 13, thereby enabling the entire box B3 to be folded flat.

[0057] This packaging box B3 is provided with a crush disposal function section 5 consisting of a line, a notch, or a combination thereof extending linearly in the widthwise center of each of the left and right side panels 12, 14, which can be folded flat by bending and guiding each of the side panels 12, 14. In this case, the crush disposal function section 5 consisting of a line, a notch, or a combination thereof is formed continuously in the vertical direction on the left side panel 12. The crush disposal function section 5 consisting of a line, a notch, or a combination thereof is formed intermittently on both vertical ends of the right side panel 14.

[0058] This packaging box B3 also has a crush disposal function section 5 consisting of a line or a notch or a combination thereof extending linearly across the entire plate of the adhesive piece 15, the extension plate 21, and the upper and lower pressure flaps 22, which can be folded and guided to fold the entire plate flat, and also has a crush disposal function section 5 consisting of a line or a notch or a combination thereof extending linearly from the point where this crush disposal function section 5 intersects with the upper and lower fold lines L13 on the extension plate 21, approximately parallel to an imaginary line connecting the start end position a1 of each fold line and the diagonal corner of each pressure flap 22 (as viewed from the start end position a1 of each fold line), which can be folded and guided to fold the entire plate flat together with the central crush disposal function section 5.

[0059] This packaging box B3 further includes a crush disposal function unit 5 consisting of a line or a cut or a combination thereof extending linearly in the center of the depth direction (vertical direction) of the inner lids 181, 191 and the outer lids 182, 192, and capable of folding the entire box B3 flat by bending and guiding the inner lids 181, 191 and the outer lids 182, 192, and also includes a crush disposal function unit 5 consisting of a line or a cut or a combination thereof extending linearly in the center of the width direction of each of the left and right flaps 183, 184, 193, 194 on the top lid 18 side and the bottom lid 19 side, and capable of folding each of the flaps 183, 193, 184, 194 flat by bending and guiding each of the flaps 183, 193, 184, 194. In this case, the crush disposal function unit 5 is continuously formed in the center of the depth direction (vertical direction) of the inner lid 181 of the canopy 18. The outer cover 182 of the canopy 18 has crushed waste function sections 5 formed intermittently on both the left and right ends at the center in the depth direction (vertical direction). The left and right flaps 183, 184 of the canopy 18 have crushed waste function sections 5 formed continuously in the center in the width direction. In this case, the inner cover 191 of the bottom cover 19 has crushed waste function sections 5 formed continuously between the wide and narrow portions. The outer cover 192 of the bottom cover 19 has crushed waste function sections 5 formed intermittently on both the left and right ends at the center in the depth direction (vertical direction). The left and right flaps 193, 194 of the bottom cover 19 have crushed waste function sections 5 formed continuously in the center in the width direction.

[0060] In this way, by providing the crush disposal function parts 5 in each part of the box B3, the box B3 can be crushed or folded flat by lightly hitting the front panel 13 of the box B3 towards the back panel 11 or in the opposite direction, or by pressing the left and right side edges of the front panel 13 and the back panel 11 together, and applying a little pressure to the front panel 13 towards the back panel 11 or in the opposite direction.

[0061] FIG. 8 shows the fourth embodiment. It illustrates the blank sheet P4 before assembly into a packaging box B4. This packaging box B4 has a configuration generally similar to that of the second embodiment. Like the third embodiment, it includes an opened display unit 3A, a resealing unit 4, and a crush disposal unit 5. Furthermore, the addition of a new crush disposal unit 5 to some of the four side panels results in a configuration that differs from that of the third embodiment. In this case, only the configuration of the crush disposal unit 5 differs from that of the third embodiment, across the entirety of the adhesive strip 15, extension plate 21, and upper and lower pressure flaps 22. Therefore, in describing this embodiment, components common to the second and third embodiments will be assigned common reference numerals, and redundant descriptions will be omitted. Differences from the third embodiment will be described using new reference numerals.

[0062] This packaging box B4 is provided with a crush disposal functional section 5 consisting of a crease, a notch, or a combination thereof extending linearly across the widthwise center of the entire plate, consisting of the adhesive piece 15, the extension plate 21, and the upper and lower pressure flaps 22, in this case, along the fold line L14 between the adhesive piece 15 and the extension plate 21, and which can be folded and guided to fold the entire plate flat. Additionally, the packaging box B4 is provided with a crush disposal functional section 5 consisting of a crease, a notch, or a combination thereof extending linearly from each intersection of the crush disposal functional section 5 and the upper and lower edges of the adhesive piece 15 toward the arc-shaped corners of the pressure flaps 22, which can be folded and guided to fold the entire plate flat together with the crush disposal functional section 5 between the adhesive piece 15 and the extension plate 21, in particular. Note that a portion of the crush disposal functional section 5 between the adhesive piece 15 and the extension plate 21 also serves as the fold line L14.

[0063] Even in this case, the same effects as those of the second and third embodiments can be achieved.

[0064] In the above-described embodiments, the cushioning function section 2 capable of pressing and holding the medicine packs is provided on both the top opening 10U side and the bottom opening 10D side of the box B4, but depending on the size (particularly the length) of the boxes B1-B4, that is, if the gap that occurs in the longitudinal direction when the medicine packs are placed in the boxes B1-B4 is relatively small, the cushioning function section 2 may be provided only on either the top opening 10U side or the bottom opening 10D side of the boxes B1-B4 to press and hold the medicine packs. This configuration can also achieve the same effects as the above-described embodiments.

[0065] In the above embodiments, boxes B1-B4 are exemplified as being of a so-called four-flap type, in which the top and bottom lids are made up of a pair of flaps, an inner lid, and an outer lid, but boxes B1-B4 may also be of a so-called three-flap type, in which the top and bottom lids are made up of a pair of flaps and a lid. Even in a three-flap type, the buffer function unit 2, the opened display function unit 3A, the resealing function unit 4, and the crushed waste function unit 5 can be applied in the same manner as in the above embodiments, and the same effects as in the above embodiments can be achieved.

[0066] In the above-described embodiments, the extension plate 21 extends in any shape from almost the entire tip edge of the adhesive piece 15, but this extension plate may be divided into the upper and lower parts of the tip edge of the adhesive piece and extended in any shape from a part of the tip edge of the adhesive piece 15. Even in this case, the same effects as those of the above-described embodiments can be achieved.

[0067] In each of the above embodiments, boxes B1-B4 are exemplified as boxes for packaging pharmaceuticals, but boxes B1-B4 may also be used to package various items other than pharmaceuticals, and by being provided with a buffer function section 2, an opened display function section 3A, a resealing function section 4, and a crushed disposal function section 5 in the same manner as in each of the above embodiments, it is possible to achieve the same effects as in each of the above embodiments.
