Description

[Technical field]

[0001] The present invention relates to a packaging box with a cushioning 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 PTP sheets then further packed in pillowcase packaging or bound together with cable ties, and packaged together in a packaging box (individual packaging box).

[0003] This type of packaging box, as disclosed in, for example, Patent Document 1, is made up of four side panels that are connected in parallel to each other and form a front part, a back part, a left side part, and a right side part, an adhesive strip formed along one side edge of each panel, a pair of flaps and a lid formed on both ends of the four side panels, a top cover forming a top part, and a bottom cover forming a bottom part, and is constructed by adhering the adhesive strips on one side edge of the four side panels to the other side edge. In the process of packaging medicines in this way, the four side panels are folded into a rectangular prism shape, medicines are placed inside, each part of the bottom cover is folded and adhered, and the top opening of the box is sealed with the lid, and the box is assembled into a substantially rectangular parallelepiped shape as a whole. In this way, medicines are packaged.

[0004] In addition, in the past, this type of medical drug was accompanied by a package insert that described various information about the drug, such as the name of the drug, how to take it (dosage, dosage, etc.), efficacy, and handling precautions, and was included in the packaging box. This package insert is made of relatively large paper, such as A3 size, and is folded into a long and thin shape to be placed in the box. The package insert folded in this way is relatively thick. Then, this package insert is stored in the box in a long and thin state, sandwiching the drug. In this way, the package insert holds the drug in the box and protects it from impacts from outside the box. However, due to the amendment of the Pharmaceutical and Medical Device Act in November 2019, this package insert is, in principle, provided by electronic means, 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 not be included in the packaging box, there will be a gap inside the box to accommodate the package insert, which may cause the medicine to rattle inside the box and reduce its protective performance. For this reason, the design of the previous box 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] With the conventional packaging boxes (individual packaging boxes) mentioned above, if the size (dimensions) of the box is reduced to match the overall size (dimensions) of the pharmaceutical product (a pharmaceutical product bundled together by packing multiple tablets or capsules in sealed PTP sheets in multiple units, or by binding them together with cable ties), there will be no gaps inside the box. However, changing the size of the box not only requires adjustments to the settings of the cartoner (a machine that packs items into boxes while forming packages), but also requires changes to the sizes of the bulk boxes that contain multiple individual packaging boxes, and the cardboard boxes that contain multiple bundled boxes. This creates a problem of heavy burden on the pharmaceutical packaging process, as it requires a wide range of changes.

[0007] Furthermore, in the past, many boxes of this type have been proposed that have a cushioning function inside the box to protect pharmaceuticals. However, in many cases, in order to integrate the cushioning function part 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 higher costs compared to boxes without a cushioning function part.

[0008] The present invention solves such problems in the past by allowing pharmaceuticals to be fixed inside the box even if space equivalent to the gap for inserting the previous package insert is left inside the box, eliminating the need to change the size of the box and eliminating the impact on others that would result from changing the size of the box; and by making the cushioning functional part of an extremely simple structure so that it can be provided without using a large amount 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 The present invention is provided with four side panels which are connected in parallel to one another and which form a front portion, a back portion, a left side portion, and a right side portion, an adhesive piece formed in accordance with one side edge of a connecting side of one side panel on one side of the four side panels which is connected to a side edge of one side panel on the other side of the four side panels, a pair of flaps formed in conjunction with both end edges of two side panels which face each other among the four side panels, and a cover formed on both end edges of one side panel or two side panels other than the two side panels, which form a top cover which covers an opening on the top surface, and a bottom cover which covers an opening on the bottom surface, and the adhesive piece and the one side panel on the other side of the four side panels are joined to form a cover on one side edge of the connecting side of the one side panel on one side and the other side panel. side a side edge of one of the side panels of the first and second side panels is connected to each other, the bottom opening is closed by the bottom lid, and the top opening is closed by the top cover, thereby assembling the entire box into a substantially rectangular parallelepiped box, for packaging medicines and various other articles, A cushioning function part capable of holding and holding an article is provided inside the box, The buffer function portion is A pair of extension plates are provided on both sides of the top cover and / or the bottom cover and are foldably extended to the inner surface of the cover; a pair of push-down plates arranged between the tips of the pair of extension plates and the tips of the flaps of the top cover and / or the bottom cover so as to be capable of pushing down and guiding the flaps into the box; The present invention is configured to include By assembling the box, the pressing plates extending from the inner surface of the lid into the box press the flaps below the top opening and / or the bottom opening, and the flaps press and hold medicines and other various items. The gist of the present invention is as follows.

[0010] Moreover, it is preferable that the packaging box has the following configuration. (1) Each of a pair of extension plates is formed on both side edges of the lid, with the side edges serving as the lower base and the upper base being biased toward the tip of the lid, in an approximately trapezoidal shape extending outside the lid, or alternatively in an approximately triangular shape, each of a pair of flaps is formed on each edge of the two side panels, with the edge serving as the lower base and the upper base being biased away from the lid, in an approximately trapezoidal shape extending outside the two side panels, or alternatively in an approximately triangular shape, each of a pair of push-down plates is formed in an approximately triangular shape between the hypotenuse of each extension plate extending from the intersection of the lower base of each extension plate and the lower base of each flap and the hypotenuse of each flap. (2) At least one of the pair of pressure plates has a portion separated from the pressure plate and the extension plate, and the portion protrudes from the oblique side of the flap as a pressing piece. In this case, it is preferable that the pressing piece protrudes from one end side of the oblique side of the flap at the intersection point between the lower bottom of the extension plate and the lower bottom of the flap, or from the opposite other end side, or from the middle between them. In this case, it is desirable that the pressing piece be separated from a part of the pressing plate by a cut line that is approximately U-shaped, approximately V-shaped or approximately C-shaped, and be formed into an approximately rectangular, approximately semi-oval, approximately triangular or approximately semicircular shape that continues from the hypotenuse of the flap. In this case, it is preferable that the pressing piece is formed so that a part of the pressing piece is separated and extends from the pressing plate to the extension plate. Effect of the Invention

[0011] The cushioning-equipped packaging box of the present invention has the above-mentioned configuration, and thus provides the following unique and special effects.

[0012] That is, this packaging box is provided with a cushioning function part capable of holding and holding medicines and various other items inside the box, so that the medicines can be fixed inside the box even if a space equivalent to the gap for inserting the previous package insert is left inside the box. This makes it unnecessary to change the size of the box, and eliminates the impact on others caused by changing the size of the box.

[0013] This cushioning function section consists of a pair of extension plates that are foldably extended onto the inner surface of the top and / or bottom lid on both sides of the lid, and a pair of press down plates that are connected between the tips of the pair of extension plates and the tips of each flap on the top and / or bottom lid so as to be able to press down and guide each flap into the box.When the box is assembled, each press down plate extending from the inner surface of the lid into the box presses down each flap below the top opening and / or bottom opening, and these flaps hold down and hold medicines and other various items.Therefore, the cushioning function section 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.

[0014] Therefore, this packaging box can effectively protect medicines and other various items contained in the box while suppressing increases in costs. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Next, the embodiments of the present invention will be described with reference to the drawings. A first embodiment is shown in Fig. 1 to Fig. 4. Fig. 1 shows the overall configuration of a packaging box with a cushioning function, and Fig. 2 to Fig. 4 show the configuration of the main parts of the packaging box. Fig. 5 shows the configuration of a blank sheet before the packaging box is assembled. In this embodiment, the packaging box is illustrated as a box made of paperboard or other paper material for packaging glass or plastic bottles (hereinafter referred to as vials) that contain medicinal liquids, and the vials are individually stored upright.

[0017] As shown in FIG. 1 and FIG. 5, the packaging box B1 with a cushioning function (hereinafter, simply referred to as packaging box B1 or box B1) is made up of four side panels 11-14 formed in parallel and connected to one another, which form a front part, a back part, a left side part, and a right side part, and an adhesive piece 15 formed in accordance with one side edge of a connecting side connected to a side edge of one side panel on one side of the four side panels 11-14 on the other side, a pair of flaps 16RF, 16LF, 17FF, 17RF formed in connection to both ends of two mutually opposing side panels among the four side panels 11-14, and lids 16C, 18L, 18R formed on both ends of one side panel or two side panels other than these two side panels, and is provided with a top cover 16 that closes the top opening, and a bottom cover 17 that closes the bottom opening, and the adhesive piece 15 and one side panel on the other side of the four side panels 11-14 are joined to form one side edge of the connecting side of one side panel on one side and the other side The side edge on the connection side of one of the side panels is connected, and the bottom opening is closed with a bottom lid 17 and the top opening is closed with a top lid 16, so that the whole is assembled into a roughly rectangular box for packaging vials.

[0018] In the case of this box B1, the four side panels 11-14, prior to assembly into the box B1, are, in order from the left, a front panel 11, a right side panel 12, a back panel 13, and a left side panel 14, with one side panel on one side (in this case, the left side) of the four side panels 11-14 being the front panel 11, and one side panel on the other side (in this case, the other right side) being the left side panel 14. The front panel 11 and the back panel 13 are each vertically long rectangles of the same size, and the left and right side panels 12, 14 are each vertically long rectangles of the same size but slightly narrower than the front panel 11 and the back panel 13. The adhesive piece 15 is about one-third the width of each of the left and right side panels 12, 14, and extends from the side edge of the front panel 11 on the left side panel 14 side into a generally trapezoidal shape with this side edge as the base. Thus, the outer surface of adhesive piece 15 is glued to the inner surface of left side panel 14 on the side of front panel 11 (right side before assembly), and the four side panels 11-14 before assembly are assembled into a cylindrical shape with a roughly rectangular horizontal cross section.

[0019] In the case of this box B1, the canopy 16 is of a three-flap type, comprising a pair of upper flaps 16LF, 16RF formed respectively adjacent to the upper edges of two opposing side panels out of the four side panels 11-14, and an upper cover 16C formed on the upper edge of another side panel other than these two side panels.

[0020] In this case, the upper flaps 16LF, 16RF are formed continuously with the upper edges of the side panels constituting the left and right sides, i.e., the left side panel 14 and the right side panel 12. In this box B1, a composite panel 16S is integrally provided between both left and right side edges of the top lid 16C and the upper edges of the left and right side panels 14, 12, and each of the upper flaps 16LF, 16RF is formed in a generally trapezoidal shape extending upward and outwardly of each of the side panels 14, 12 on part of the composite panel 16S, with the upper edges of the left and right side panels 14, 12 as its lower base and offset to one side so as to face one end side away from the top lid 16C at its lower base. Here, the height (height between the upper base and lower base) of each upper flap 16LF, 16RF is formed to be slightly shorter than half the dimension between the upper edges of each of the left and right side panels 14, 12 after assembly to the box B1 (the dimension in the width direction (left and right direction) of the top opening), and each upper flap 16LF, 16RF is designed to partially cover both the left and right sides of the top opening of the box B1.

[0021] In this case, the top cover 16C is a side panel forming the rear portion, i.e., is formed into a generally square shape that is continuous with the upper edge of the rear panel 13 and has an insertion piece 16C1 at its tip in a semi-racetrack shape.

[0022] The bottom cover 17 is of a four-flap type and comprises a pair of lower flaps 17FF, 17RF formed respectively adjacent to the lower edges of two opposing side panels out of the four side panels 11-14, and a pair of lower covers 18L, 18R formed respectively on the lower edges of two other side panels other than the two side panels.

[0023] In this case, each of the lower flaps 17FF, 17RF is formed continuously with the lower edge of the front panel 11 and the rear panel 13. In this box B1, a vertically long, approximately rectangular composite plate 17S is integrally provided with the lower edge of the front panel 11 and the rear panel 13, and each of the lower flaps 17FF, 17RF is formed in a part of each composite plate 17S in an approximately trapezoidal shape extending downward and outward from the front panel 11 and the rear panel 13, with the lower edge of each of the front panel 11 and the rear panel 13 as the lower base and a position at a predetermined height from the lower base as the upper base. Here, each of the lower flaps 17FF, 17RF is formed to have the same height (the height between the upper base and the lower base is the same) and is slightly shorter than half the dimension between the lower edges of the front panel 11 and the rear panel 13 after assembly to the box B1 (the dimension in the depth direction (front-rear direction) of the bottom opening), and each of the lower flaps 17FF, 17RF is configured to partially cover both the front and rear sides of the bottom opening of the box B1.

[0024] In this case, each of the lower covers 18L, 18R is formed into a trapezoidal shape approximating a right-angled triangle with its lower end continuing from the lower edge of the left side panel 14 and the right side panel 12 as its lower base. In this box B1, the lower cover 18L on the left side panel 14 side has one corner on the rear panel 13 side that forms a right angle, and the lower cover 18R on the right side panel 12 side has one corner on the front panel 11 side that forms a right angle. Each of the lower covers 18L, 18R has fold lines L16, L17 perpendicular to the oblique line from one corner that forms a right angle to the oblique line so that they can be folded into the inside of the box B1 along one diagonal line of the bottom opening of the box B1 together with the lower flaps 17FF, 17RF. Each lower cover 18L, 18R is overlapped on the outside of each lower flap 17RF, 17FF so that the hypotenuse is positioned along the other diagonal of the bottom opening, and the inner surface of each lower cover 18L, 18R from the fold lines L16, L17 to the tip side is adhered to the outer surface of each lower flap 17RF, 17FF via glue.

[0025] As shown in Figures 2 to 4, inside this box B1, the bottom lid 17 is provided with a bottom lid side buffer function section 3 capable of supporting a vial, and the lid 16 is provided with a lid side buffer function section 2 capable of pressing down and holding the vial from above.

[0026] 2 and 5, the buffer function section 3 on the bottom cover side is configured to be able to hold the bottom and outer periphery of a vial on the bottom cover 17 inside the box B1. In the case of this box B1, the buffer function section 3 is provided on the inner surface of a pair of lower flaps 17FF, 17RF with a buffer space 30 interposed therebetween, and is configured by a pair of pedestals 31 having a support groove 310 capable of supporting the bottom of the vial and a holding groove 312 capable of holding the outer periphery of the vial.

[0027] In this case, the pair of pedestals 31 are formed on the remaining parts of the composite plate 17S integrally provided on the lower edges of the front plate 11 and rear plate 13, respectively, on the extensions of the lower flaps 17FF, 17RF. Each base 31 comprises a pair of vertical support plates 311 which are continuous with the tips of the respective lower flaps 17FF, 17RF, are raised from the tips of the respective lower flaps 17FF, 17RF at approximately right angles toward the inside of the box B1 to a predetermined height, and have support grooves 310 extending downward from their upper ends; a pair of horizontal support plates 313 which extend from the upper ends of the respective vertical support plates 311 parallel to the respective lower flaps 17FF, 17RF to the respective side panels 11, 13, and have support grooves 312 at one end corresponding to the upper end side of each vertical support plate 311, which are continuous with the support grooves 310 of the vertical support plates 311; and a pair of fixing plates 314 which extend from the other end of each horizontal support plate 313 on the side panel 11, 13 side along the respective side panels 11, 13 to the respective lower flaps 17FF, 17RF or in the direction of the respective lower flaps 17FF, 17RF, and whose outer surfaces abut against the inner surfaces of the respective side panels 11, 13. In this case, each support groove 310 is a rectangular groove capable of supporting the bottom of a vial, and the holding groove 312 is an arc-shaped groove capable of holding the outer periphery of a vial. The outer surface of each fixing plate 314 of each pedestal 31 is fixed to the inner surface of each side plate 11, 13 via glue, and each pedestal 31 is configured on each lower flap 17FF, 17RF as a groove having a substantially U-shape in plan view relative to the front plate 11 and the rear plate 13. Thus, a pair of pedestals 31 is formed on each lower flap 17FF, 17RF with a buffer space 30 therebetween, and a vial storage section 315 is formed between each pedestal 31.

[0028] In addition, the pair of bases 31 have locking pieces 316 protruding from the lower end of each vertical support plate 311 between the lower flaps 17FF, 17RF so as to be mutually engageable. In this case, the locking piece 316 of one vertical support plate 311 is formed by cutting a cutting line in the shape of a blade tip (the cutting edge of a sword) into the lower half of the bottom of the support groove 310, in this case, the left half, to the lower end of this vertical support plate 311, and protruding from the tip of one lower flap 17RF toward the other lower flap 17FF. Similarly, the locking piece 316 of the other vertical support plate 311 is formed by cutting a cutting line in the shape of a blade tip into the lower half of the bottom of the support groove 310, in this case, the left half, to the lower end of this vertical support plate 311, and protruding from the tip of the other lower flap 17FF toward one lower flap 17RF. By the engagement of these locking pieces 316, the box B1 in its assembled state is maintained in its configuration as the bottom lid 17 and as the storage section 315 for a vial between the pair of pedestals 31.

[0029] 3 and 4, the cushioning function section 2 on the lid side is configured to be able to hold the vial from above in the box B1. In the case of this box B1, this cushioning function section 2 is configured with a pair of extension plates 21 that are foldably extended to the inner surface of the upper lid 16C of the lid 16 on both sides of the upper lid 16C of the lid 16, and a pair of pressing plates 22 that are connected and disposed between the tips of the pair of extension plates 21 and the tips of the upper flaps 16LF, 16RF of the lid 16 so as to be able to press and guide the upper flaps 16LF, 16RF into the box.

[0030] In this case, the pair of extension plates 21 and the pair of push-down plates 22 are each formed together with the upper flaps 16LF, 16RF of the canopy 16 on each composite plate 16S that is integrally provided between the left and right side edges of the top cover 16C and the upper edges of each of the left and right side panels 14, 12.

[0031] The pair of extension plates 21 are formed in a generally trapezoid shape extending outward from the upper cover 16C, in this case to the left and right outside, with the lower base being the left and right side edges of the upper cover 16C of each composite plate 16S, and the upper base being biased upward so as to face the tip end of the left and right side edges of the upper cover 16C. The pair of pressing plates 22 are formed in a generally triangular shape between the oblique side of each extension plate 21 extending from the intersection X of the lower base of each extension plate 21 and the lower base of each upper flap 16LF, 16RF of each composite plate 16S and the oblique side of each upper flap 16LF, 16RF.

[0032] Thus, the pair of extension plates 21 each follow the opening and closing movement of the top lid 16C, using the left and right edge portions of the top lid 16C as fulcrums, and when the top lid 16C is opened and raised onto the back panel 13, they are spaced 90° apart from the inner surface of the top lid 16C and extend approximately parallel to the left and right side panels 14, 12 from both the left and right sides of the top lid 16C, and are configured to be folded onto the inner surface of the top lid 16C and overlapped when the top lid 16C is closed and the top lid 16C is dropped onto the top opening of the box B1. In contrast, the pair of push-down plates 22 each move in conjunction with the movement of each extension plate 21, with the hypotenuse of the extension plate 21 serving as a fulcrum, and as each extension plate 21 extends from both left and right edges of the top lid 16C approximately parallel to the left and right side panels 14, 12, they extend approximately parallel to the left and right side panels 14, 12 below each extension plate 21, and as each extension plate 21 is folded and overlapped onto the inner surface of the top lid 16C, they extend from the hypotenuse of each extension plate 21 in a direction perpendicular to the inner surface of the top lid 16C below the top opening of the box B1, and are configured to be able to push down the tips of each upper flap 16LF, 16RF below the top opening.

[0033] By assembling the box B1 in this manner, a pair of pedestals 31 constituting the buffer functional portion 3 on the inner bottom lid 17 of the box B1 are raised, and the vial is stored and held in the storage portion 315 of these pedestals 31, and each of the push-down plates 22 extending from the inner surface of the top lid 16 into the box B1 pushes down each of the upper flaps 16LF, 16RF below the top opening, so that each of the upper flaps 16LF, 16RF presses down and holds the vial from above.

[0034] As shown in Fig. 5, the box B1 is made of a blank sheet P1 which is formed integrally with the buffer functional parts 2 and 3 by punching out a base paper or a printed copy. The blank sheet P1 has the following structure.

[0035] On one side of the left side, a front plate shape portion 11P is formed as a vertically elongated rectangle of a predetermined size and forming the front portion of the box B1, and on one long side of the right side of this front plate shape portion 11P, a right side plate shape portion 12P having approximately the same size and shape as the front plate shape portion P11 and forming the right side portion, a back plate shape portion 13P having approximately the same size and shape as the front plate shape portion 11P and forming the back portion, and a left side plate shape portion 14P having approximately the same size and shape as the front plate shape portion 11P and forming the left side portion are successively formed continuously via fold lines L1, L2, and L3, and on the other long side of the left side of the front plate shape portion 11P, an adhesive piece shape portion 15P forming an adhesive piece 15 is formed continuously via fold line L4 in a vertically elongated band shape, in this case approximately trapezoidal with this long side as the base.

[0036] A vertically long, approximately rectangular composite plate shaped portion 17SP is continuously formed on the other lower short side of the front plate shaped portion 11P and the other lower short side of the back plate shaped portion 13P, and lower flap shaped portions 171P, 172P forming lower flaps 17FF, 17RF are continuously formed via fold lines L12, L13 at the ends of the front plate shaped portion 11P side and the back plate shaped portion 13P side of these composite plate shaped portions 17SP, respectively, and are approximately trapezoidal with the other lower short side of the front plate shaped portion 11P and the other lower short side of the back plate shaped portion 13P as their lower bases, with a length slightly shorter than half the front-to-rear length of the bottom opening.

[0037] A lower cover portion 192P, which is a trapezoidal shape resembling a right-angled triangle protruding at a right angle from the end of the rear plate portion 13P side and which constitutes the left lower cover 18L, is formed continuously through a fold line L14 on the other short side of the lower side of the left side panel portion 14P. Similarly, a lower cover portion 191P, which is a trapezoidal shape resembling a right-angled triangle protruding at a right angle from the end of the front plate portion 11P side and which constitutes the right lower cover 18R, is formed continuously through a fold line L15 on the other short side of the lower side of the right side panel portion 12P. Each lower cover portion 192P, 191P is provided with a fold line L16, L17 at a right angle from one corner forming a right angle toward the oblique side.

[0038] A pedestal shaped portion 31P is formed on the tip of each of the lower flap shaped portions 171P, 172P, i.e., the remaining portion of each composite plate shaped portion 17SP, forming a pair of pedestals 31 constituting the bottom cover side cushioning function portion 3. Each pedestal shaped portion 31P has the same size and shape, and is formed so that the entire portion can be bent into a substantially inverted U shape on each of the lower flap shaped portions 171P, 172P, and is composed of a vertical holding plate portion 311P, a horizontal holding plate portion 313P, and a fixing plate portion 314P.

[0039] Each vertical support plate portion 311P is formed in a substantially rectangular shape of a predetermined length, continuing from the tip of each lower flap shaped portion 171P, 172P via folding lines L18, L19.

[0040] Each horizontal support plate portion 313P is connected to the tip of each vertical support plate portion 311P via bend lines L20, L21 and is formed into a substantially rectangular shape having the same length as each lower flap shaped portion 171P, 172P.

[0041] Each fixing plate portion 314P is connected to the tip of each horizontal support plate portion 313P via bend lines L22, L23 and is formed into a substantially rectangular shape having a length equal to or slightly shorter than that of each vertical support plate portion 311P.

[0042] Then, on each folded line L20 between each vertical holding plate portion 311P and each horizontal holding plate portion 313P, the vertical holding plate portion 311P side is cut into a U-shape from two specific points on both ends on each folded line L21, and the horizontal holding plate portion 313P side is cut into an arc shape from the same two points, so that a U-shaped support groove 310 is formed in each vertical holding plate portion 311P, and an arc-shaped holding groove 312 is formed in each horizontal holding plate portion 313P.

[0043] A top cover shaped portion 18P that is approximately square and approximately the same size as the top opening and forms top cover 16C is formed continuously on one of the upper short sides of back panel shaped portion 13P via fold line L5, and on the extension of its tip, a horizontally elongated band-like (semi-racetrack-shaped) insertion piece shaped portion 181P that forms insertion piece 16C1 of top cover 16C is formed continuously via fold line L6.

[0044] A pair of composite plate-shaped portions 16SP are integrally formed between the left and right side edges of the top cover portion 18P and the upper edges of the left and right side plate-shaped portions 14P, 12P.

[0045] In the left composite plate-shaped portion 16SP, a top flap-shaped portion 162P is formed on a part of the left side panel-shaped portion 14P side, which is continuous with the fold line L7 and is a trapezoid slightly shorter than half the length of the top cover 16C, with one upper short side of the left side panel-shaped portion 14P as the bottom base. In the right composite plate-shaped portion 16SP, a top flap-shaped portion 161P is formed on a part of the right side panel-shaped portion 12P side, which is a trapezoid slightly shorter than half the length of the top cover 16C, with one upper short side of the right side panel-shaped portion 12P as the bottom base, with this short side as the bottom base, with the top flap-shaped portion 161P being a trapezoid slightly shorter than half the length of the top cover 16C, with this short side as the bottom base, and is continuous with the right side of the right side panel-shaped portion 12P, which is continuous with the fold line L8.

[0046] The tip of each upper flap shaped portion 162P, 161P, i.e., the remaining portion of each composite plate shaped portion 16SP, is formed with a pair of extension plates 21 constituting the cushioning function portion 2 on the canopy side, a pair of extension plate shaped portions 21P constituting a pair of press-down plates 22, and a pair of press-down plate shaped portions 22P.

[0047] Each of the pair of extension plate-shaped portions 21P is formed into an approximately trapezoidal shape extending outside the upper cover portion 18P, in this case to the left and right outside, with each side edge serving as a lower base and each upper base being biased upward so as to face the tip end portion of each of the left and right side edges of the upper cover portion 18P, via fold lines L9, L10 in each composite plate-shaped portion 16SP.

[0048] Each of the pair of presser plate-shaped portions 22P is formed in an approximately triangular shape between the hypotenuse of each extension plate-shaped portion 21P extending from the intersection X between the lower base of each extension plate-shaped portion 21P and the lower base of each upper flap-shaped portion 162P, 161P in each composite plate-shaped portion 16SP and the hypotenuse of each upper flap-shaped portion 162P, 161P.

[0049] While being transported in the forward direction by a pasting machine (not shown), this blank sheet P1 has predetermined portions coated with glue and each portion is folded in order as follows: Note that this blank sheet P1 is transported with the front side (printing surface) facing downwards, with the pedestal portions 31P at the tips of the lower flap portions 171P, 172P facing in the forward direction.

[0050] First, the blank sheet P1 is folded 180 degrees along the fold lines L20 and L21 so that the back surfaces of the base-shaped portions 31P (the surfaces that will be on the inside when assembled into the box B1 (i.e., the inner surfaces)) are aligned with each other. Then, glue is applied to the center of the front surface side of each fixing plate portion 314P.

[0051] Next, the blank sheet P1 is folded 180 degrees along the fold lines L12 and L13 so that the front surface of each fixing plate portion 314P after folding of each pedestal portion 31P is aligned with the back surface of the front plate portion 11P and the back surface of the back plate portion 13P, respectively. As a result, the front surface of each fixing plate portion 314P is bonded with the back surface of the front plate portion 11P and the back surface of the back plate portion 13P by glue.

[0052] Next, the blank sheet P1 is folded 180 degrees along the fold lines L14 and L15 so that the back surfaces of the lower lid portions 192P and 191P and the back surfaces of the left and right side panel portions 14P and 12P meet each other. At substantially the same time, the blank sheet P1 is folded 180 degrees along the fold lines L16 and L17 so that the front surfaces of the lower lid portions 192P and 191P meet each other.

[0053] Here, glue is applied to the center of the front side of the lower flap-shaped portion 171P and the center of the rear side of the lower lid-shaped portion 191P on the tip side of the fold line L17. At roughly the same time, glue is applied in a long, thin strip parallel to the front side of the adhesive piece-shaped portion 15P along the fold line L4.

[0054] Next, the blank sheet P1 is folded 180 degrees along the fold line L1 so that the back surface of the front plate portion 11P is aligned with the back surface of the right side plate portion 12P via the base portion 31P and the lower cover portion 191P.

[0055] Then, the blank sheet P1 is folded 180 degrees along fold line L3 so that the back surface of left side panel portion 14P is joined to the back surface of back panel portion 13P via lower lid portion 192P, adhesive piece portion 15P and base portion 31P.

[0056] In this way, the blank sheet P1 is folded flat, and sufficient pressure is applied to the entire blank sheet P1. As a result, the portion of the blank sheet P1 to which glue is applied and the portion overlapping this portion are pressed together and bonded. That is, the front side of the lower flap shape portion 171P and the back side of the lower lid shape portion 191P are aligned with the leading edge side of the fold line L17, and the front side of the lower flap shape portion 172P and the back side of the lower lid shape portion 192P are aligned with the leading edge side of the fold line L16, and are bonded together with glue. Then, the front side of the adhesive piece shape portion 15P and the back side of the left side panel shape portion 14P are aligned and bonded together with glue.

[0057] Thus, the blank sheet P1 is folded flat 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 pharmaceutical company.

[0058] Then, in the process of packaging the vials at the pharmaceutical company, this flattened unassembled box B1 is erected into a box shape as shown in FIG. 2, and the vials are stored inside the box B1.

[0059] In the vial packaging process, the flat unassembled box B1 is raised into a box shape with an open top opening by applying pressure from the outside to the inside of the box B1 along the folding lines L1 and L3.

[0060] That is, between the front plate shape portion 11P and the back plate shape portion 13P, the left side plate shape portion 14P and the right side plate shape portion 12P are raised approximately at right angles to the front plate shape portion 11P and the back plate shape portion 13P, respectively, and the front plate shape portion 11P, the back shape portion 13P, the left side plate shape portion 14P and the right side plate shape portion 12P are assembled as four continuous side panels 11, 13, 14 and 12 forming the front portion, back portion, left side portion and right side portion, respectively.

[0061] In conjunction with the raising of the left side panel 14 and the right side panel 12, the lower lid-shaped portions 192P and 191P are raised at a substantially right angle to the left side panel 14 and the right side panel 12 to form the lower lids 18L and 18R. The lower lids 18L and 18R are assembled into a substantially rectangular shape by aligning the oblique sides of the lower lids 18L and 18R with one diagonal of the bottom opening under the lower flaps 17RF and 17FF in the bottom opening of the box B1. In this case, the back surfaces of the portions of the lower lids 18L and 18R on the tip side from the fold lines L16 and L17 are glued and fixed to the surfaces of the lower flaps 17RF and 17FF via glue.

[0062] Furthermore, in conjunction with the raising of the lower covers 18L, 18R, the lower flap-shaped portions 172P, 171P are raised at approximately right angles to the rear plate 13 and the front plate 11 to be assembled as the lower flaps 17RF, 17FF. At the same time, the pedestal-shaped portions 31P are assembled as the pedestals 31 on the rear surfaces of the lower flaps 17RF, 17FF in an approximately inverted U-shape. In this case, each pedestal 31 has a vertical holding plate portion 311P raised at a substantially right angle to each lower flap 17RF, 17FF to form a vertical holding plate 311 having a support groove 310 extending downward from the upper end at the tip of each lower flap 17RF, 17FF, and each horizontal holding plate portion 313P raised at a substantially right angle to each vertical holding plate 311 and substantially parallel to each lower flap 17RF, 17FF to form a horizontal holding plate 313 having a holding groove 312 at one end continuing to the upper end of each vertical holding plate 311 and continuing to the support groove 310 of each vertical holding plate 311. In this case, each fixing plate portion 314P serves as a fixing plate 314, the surface of which is fixed to the rear plate 13 and the rear plate 11 via glue. Thus, a pair of pedestals 31 are formed on each of the lower flaps 17RF, 17FF of the bottom cover 17 with a buffer space 30 therebetween, and a vial storage space 315 is formed between the pedestals 31 in the center of the bottom cover 17.

[0063] In this manner, the main body of the box B1 is assembled except for the top opening, and a vial is stored in the storage section 315 at the center of the bottom cover 17 through the top opening of the box B1.

[0064] When a vial is stored in the storage section 315 from the top opening of the box B1, the weight of the vial holds the lower flaps 17FF, 17RF at right angles to the front plate 11 and rear plate 13, and holds the buffer function section 3 (each pedestal 31) of the bottom lid 17 in its original shape. At this time, the locking pieces 316 of each pedestal 31 engage with the center of the bottom lid 17, so that the shape of the bottom lid 17 is stably maintained.

[0065] When the vial is thus stored inside the box B1, the upper flap-shaped portions 162P, 161P of the composite-shaped portions 16SP on the top lid 16 side are then bent at substantially right angles to the left side panel 14 and the right side panel 12 as the upper flaps 16LF, 16RF, respectively, and the top opening of the box B1 is closed by the upper flaps 16LF, 16RF. At the same time, the push-down plate-shaped portions 22P and the extension plate-shaped portions 21P are pulled by the upper flaps 16LF, 16RF, and the push-down plate-shaped portions 22P are raised as the push-down plates 22 on the tips of the upper flaps 16LF, 16RF, and the extension plate-shaped portions 21P are extended as the extension plates 21 obliquely from both the left and right sides of the top lid portion 18P toward the inner surface of the top lid portion 18P.

[0066] Then, the top lid shaped portion 18P is bent at a substantially right angle relative to the back panel 13 toward the top opening of the box B1 to form the top lid 16C. By bending the top lid 16C in this manner, the extension plates 21 are folded and overlapped with the inner surface of the top lid 16C as shown in Fig. 3, and the top lid 16C and the extension plates 21 push the push-down plates 22 toward the top opening of the box B1.

[0067] When the top cover 16C is folded up to the top opening of the box B1 together with the extension plates 21 and the top opening is closed, the push-down plates 22 push the tips of the top flaps 16LF, 16RF below the top opening, and the whole is pushed down into the box B1, and the tips of the top flaps 16LF, 16RF press the top of the vial stored in the box B1 from above. In the case of this box B1, as shown in Fig. 4, the tips of the top flaps 16LF, 16RF, together with the tips of the push-down plates 22, form a substantially V-shape from the front panel 11 side of the box B1 to the back panel 13 side, and the tips of the top flaps 16LF, 16RF press and hold the top of the vial from above. These extension plates 21, push-down plates 22, and top flaps 16LF, 16RF play the role of cushioning material in place of the package insert that was previously included.

[0068] Then, at the same time that the top opening of box B1 is closed by the top lid, the insertion piece shaped portion 181P of top lid 16C is bent inward at a substantially right angle to form insertion piece 16C1, which is inserted into the inside of front plate 11, and the center of this insertion piece 16C1 is glued and fixed to the upper center of front plate 11. By fixing top lid 16C in this way, the extension plates 21, push-down plates 22, and upper flaps 16LF, 16RF on the inside of top lid 16C hold down the top of the vial. In this way, the vial is sealed in box B1, and inside box B1, the bottom surface of the vial is supported by the support grooves 310 of the vertical holding plates 311 of the pedestals 31, the outer periphery is held by the holding grooves 312 of the horizontal holding parts 313, and further, the upper part of the vial is pressed and held by the extension plates 21, the push-down plates 22, and the upper flaps 16LF, 16RF on the inside of the top lid 16C. As a result, the vial is subjected to the cushioning action of the pedestals 31 on the bottom lid 17 and the extension plates 21, the push-down plates 22, and the upper flaps 16LF, 16RF on the top lid 16 side, sufficiently mitigating impacts from outside box B1 and is reliably protected.

[0069] 1, this packaging box B1 has a trapezoidal perforated cut from the upper edge downward on the upper part of the front plate 11 to form a break line C1 for opening, and when opening the box B1, the opening surrounded by the break line C1 is pressed and broken. This separates the adhesive portion between the top cover 16C and the front plate 11, and the top opening of the box B1 can be opened by pulling the top cover 16C upward.

[0070] As described above, this packaging box B1 is provided with the cushioning functional part 2 capable of holding the upper part of the vial from above inside the box B1, so that the vial can be fixed inside the box B1 even if a space equivalent to the gap for inserting the previous package insert remains inside the box B1. This eliminates the need to change the size of the box B1, and eliminates other effects caused by changing the size of the box B1, such as the need to adjust the settings of the cartoner, the need to change the size of the bulk box into which multiple individual packaging boxes are placed, and the size of the cardboard box into which multiple bulk boxes are placed, and other problems such as the large burden caused by the extensive changes in the process of packaging the vials.

[0071] The buffer function section 2 comprises a pair of extension plates 21 which are foldably extended onto the inner surface of the top lid 16C of the canopy 16 on both the left and right sides of the top lid 16C, and a pair of push-down plates 22 which are connected between the tips of the pair of extension plates 21 and the tips of the upper flaps 16LF, 16RF of the canopy 16 so as to be able to push down and guide each of the upper flaps 16LF, 16RF into the box B1. When the box B1 is assembled, the push-down plates 22 extending from the inner surface of the canopy 16 into the box B1 push down each of the upper flaps 16LF, 16RF below the top opening, and each of the upper flaps 16LF, 16RF holds down and holds the top of the vial. Therefore, the buffer function section 2 has an extremely simple structure and can be provided within the box B1 without using a large amount of box material or giving the box material a complex shape.

[0072] In particular, in this packaging box B1, a composite plate 16S is formed between both left and right side edges of the top cover 16C and the upper ends of the left and right side panels 14, 12, respectively, and in each composite plate 16S, a pair of extension plates 21 are formed on both left and right side edges of the top cover 16C with these side edges as the lower base and the upper base being biased toward the tip side of the top cover 16C and extending outward from the top cover 16C in a generally trapezoidal shape. A pair of upper flaps 16LF, 16RF are formed on each of the left and right side panels 14, 12, respectively. These upper edges form the bottom base, which is formed into an approximately trapezoidal shape extending upward and outwardly of each of the left and right side panels 14, 12, with the upper edges serving as the bottom base, biased toward the end side away from the top cover 16C, and each push-down plate 22 is formed into an approximately triangular shape between the hypotenuse of each extension plate 21 extending from the intersection X between the bottom base of each extension plate 21 and the bottom base of each upper flap 16LF, 16RF, and the hypotenuse of each upper flap 16LF, 16RF, so that each part of the cushioning function can be realized with as simple a structure as possible.

[0073] Therefore, according to this packaging box B1, it is possible to effectively protect the vials in the box B1 while suppressing an increase in cost.

[0074] In addition, this packaging box B1 is provided with a top-side buffering function part 2 and a bottom-side buffering function part 3, and these buffering function parts 2, 3 hold the vial from three directions, the top, the outer periphery, and the bottom, so that the shock from the outside of the box B1 can be sufficiently absorbed and the vial can be reliably protected. Furthermore, since the top-side buffering function part 2 is formed separately from the bottom-side buffering function part 3, the top-side buffering function part 2 can be easily and inexpensively installed in boxes having various types of bottom-side buffering function parts other than the bottom-side buffering function part 3 exemplified here, and the same effects can be achieved. In this case, the bottom-side buffering function part of the other type includes a type that supports only the bottom of the vial in the box and a type that holds only the outer periphery of the vial.

[0075] Furthermore, in this packaging box B1, the cushioning functional sections 2, 3 can be formed from a single sheet of paperboard P1, which can further simplify the manufacturing process and contribute to reducing costs.

[0076] The second embodiment is shown in Figs. 6 to 14. Fig. 6 shows the overall configuration of the packaging box with a cushioning function, and Figs. 7 and 8 show the configuration of the main parts of the packaging box. Fig. 9 shows the configuration of the blank sheet before the packaging box is assembled. This packaging box is obtained by adding a new configuration to the cushioning function part on the canopy side in the first embodiment, and has the same configuration as the first embodiment except for this new configuration. Therefore, in the explanation of this embodiment, the same symbols are used for the configurations common to the first embodiment and the duplicated explanations are omitted, and new symbols are used to explain the new configuration of the cushioning function part on the canopy side.

[0077] 6, 7, 8 and 9, in a packaging box B2 with a cushioning function (hereinafter simply referred to as packaging box B2 or box B2), at least one of a pair of presser plates 22 is partially detached from the presser plate 22 and the extension plate 21, and this portion protrudes from the oblique side of the upper flap as a pressing piece 221. In the case of this box B2, both of the pair of presser plates 22 are partially detached from each presser plate 22 and each extension plate 21, and each portion protrudes from the oblique side of each upper flap 16LF, 16RF as a pressing piece 221. In this case, each pressing piece 221 protrudes from one end side on the side of each intersection X described above, or the opposite other end side, or the middle between them, on the oblique side of each upper flap 16LF, 16RF.

[0078] In this case, each pressing piece 221 is separated from a part of the middle part of each pressing plate 22, in other words, between the middle part (approximately the center) of the hypotenuse of each extension plate 21 and the middle part (approximately the center) of the hypotenuse of each upper flap 16LF, 16RF by an approximately C-shaped cut line 220 that spans each extension plate 21, and is formed into an approximately rectangular shape that continues to the hypotenuse of each upper flap 16LF, 16RF, i.e., (a part of) the tip of each upper flap 16LF, 16RF. More specifically, each of these cut lines 220 has one outer end on the hypotenuse of each upper flap 16LF, 16RF when viewed from each intersection X, and the other inner end on the hypotenuse of each extension plate 21, so that overall it forms a roughly U-shape, and from the other end of each of these cut lines 220, the cut lines 220 further deviate slightly from the hypotenuse of each extension plate 21 and extend to a position slightly toward the other end side of each of the left and right side edges of the top cover 16C beyond one end of each intersection X side, and are formed from there to each intersection X, and each pressing piece 221 extends from the center of the tip of each upper flap 16LF, 16RF, and one side edge of each pressing piece 221 is supported by a protruding edge 222 that protrudes from the end side edge on the intersection X side at the tip of each upper flap 16LF, 16RF.

[0079] 10 to 12, when the top cover 16C is folded together with the extension plates 21 up to the top opening of the box B2 and the top opening is closed, the tips of the top flaps 16LF, 16RF are pressed down below the top opening by the pressing plates 22, and the entire top flaps 16LF, 16RF are pressed down diagonally into the box. As a result, as shown in Fig. 13, the pressing pieces 221 extending from the center of the tips of the top flaps 16LF, 16RF press down the upper surface of the top of the vial stored in the center of the box B2, and the top of the vial stored in the box B2 is pressed down and held from above by the tips of the top flaps 16LF, 16RF.

[0080] This arrangement can achieve the same effect as the first embodiment, and in particular in this embodiment, since each pressing piece 221 presses down on the upper surface of the vial, the pressing area on the upper part of the vial is expanded, enabling the vial to be more securely pressed down and held.

[0081] In addition, in the case of this box B2, after opening the canopy 16, when closing the canopy 16, as shown in Figure 14 (1), the upper flaps 16LF, 16RF of the canopy 16 are pushed toward the top opening of box B2 with the thumb or index finger, and as shown in Figure 14 (2), the top cover 16C is pushed down onto the top opening of box B2 with the thumb or the like, and the insertion piece 16C1 of the top cover 16C is inserted inside the front panel 11, thereby closing the canopy 16 and resealing it.

[0082] 15 to 17 show the third embodiment. FIG. 15 shows the overall configuration of the packaging box with a cushioning function, and FIG. 16 shows the configuration of the main parts of the packaging box. FIG. 17 shows the configuration of the blank sheet before assembly of the packaging box. In this packaging box, each upper flap is formed into a substantially triangular shape instead of a substantially trapezoidal shape in the second embodiment, and a new configuration slightly different from that of the second embodiment is added to the cushioning function part on the lid side. In addition, the bottom lid is composed of four flaps, and the cushioning function part is not provided on this bottom lid. In the case of this box, the vial is stored by being placed directly on the bottom lid in the box. That is, in this box, a part of the cushioning function part on the lid side and the bottom lid have a different configuration from that of the first embodiment, and the other parts have a common configuration with the second embodiment. Therefore, in the description of this embodiment, the same reference numerals are given to the configurations common to the second embodiment, and the overlapping description is omitted, and new reference numerals are given to the configuration of the cushioning function part on the lid side and the configuration of the bottom lid.

[0083] 15, 16 and 17, in a packaging box B3 with a cushioning function (hereinafter simply referred to as packaging box B3 or box B3), at least one of a pair of presser plates 22 is partially detached from the presser plate 22 and the extension plate 21, and this portion protrudes from the oblique side of the upper flap as a pressing piece 221. In the case of this box B3, both of the pair of presser plates 22 are partially detached from each presser plate 22 and each extension plate 21, and each portion protrudes from the oblique side of each upper flap 16LF, 16RF as a pressing piece 221. In this case, each pressing piece 221 protrudes from one end side on the side of each intersection X described above, or the opposite other end side, or the middle between them, on the oblique side of each upper flap 16LF, 16RF.

[0084] In the case of this box B3, each pressing piece 221 is separated into an approximately V-shape as a whole by a substantially straight cut line 220, part of which spans the extension plate 21, between the other end side opposite to one end side of each intersection point X of each presser plate 22, in other words, between the other end side opposite to one end side of each intersection point X of the hypotenuse of each extension plate 21 and the other end side opposite to one end side of each intersection point X of each upper flap 16LF, 16RF, and is formed into an approximately triangular shape continuing to the hypotenuse of each upper flap 16LF, 16RF, i.e., (part of) the tip of each upper flap 16LF, 16RF.

[0085] In addition, in the case of this box B3, an approximately U-shaped cut line 230, part of which spans the extension plate 21, is formed on one end side of each intersection point X of each push-down plate 22, in other words, between one end side of each intersection point X of the hypotenuse of each extension plate 21 and one end side of each intersection point X of the hypotenuse of each upper flap 16LF, 16RF, and an approximately rectangular protruding edge portion 231 is formed continuing from the hypotenuse of each upper flap 16LF, 16RF, i.e., from (part of) the tip of each upper flap 16LF, 16RF. More specifically, each of these cut lines 230 has an outer end on the oblique side of each upper flap 16LF, 16RF when viewed from the intersection point X side, and an inner end on the intersection point X side of each extension plate 221, forming a horizontally long trapezoidal shape generally in the shape of a U. In this case, a part of the cut line 230 corresponding to the upper base of the trapezoid is slightly off the oblique side of each extension plate 21 and extends to a position slightly toward the other end side from one end of each intersection point X side of each left and right side edge of the upper cover 16C, and is formed from there to each intersection point X along each left and right side edge of the upper cover 16C. Thus, each protruding edge 231 is formed in a generally trapezoidal shape from the center of the tip of each upper flap 16LF, 16RF to the end on the intersection point X side.

[0086] In the case of box B3, the bottom cover 4 is composed of a pair of composite-shaped bottom plates 41 connected to the lower edges of the four side panels 11-14, in this case the lower edges of the front panel 11 and the back panel 13, via fold lines L12, L13, and having a convex portion E1 and an uneven portion E2 at their tips, which are capable of closing approximately half of the front and rear sides of the bottom opening of box B3, and a pair of approximately trapezoidal lower flaps 42 connected to the lower edges of the left and right side panels 14, 12 via fold lines L14, L12, which are capable of closing both the left and right sides of the bottom opening of box B3, and each bottom plate 41 is glued to the left and right lower flaps 42 at the bottom opening of box B3, and the convex portions E1 and uneven portions E2 of each bottom plate 41 engage with each other, so that each bottom plate 41 is combined to form a horizontally long rectangle.

[0087] Thus, the box B3 is folded flat as described above. Then, in the vial packaging process, the box is erected into a box shape, and the vials are placed in the box B3 through the top opening. After the vials are placed in the box B3, the top opening is closed with the lid 16.

[0088] That is, when the top cover 16C is folded up to the top opening of the box B3 together with the extension plates 21 to close the top opening, the pushing plates 22 push the tips of the top flaps 16LF, 16RF below the top opening, and the entire top flaps 16LF, 16RF are pushed down diagonally into the box B3, as shown in Fig. 16. As a result, the upper surfaces of the upper parts of the vials stored in the box B3 are pressed down by the pressing pieces 221 extending from approximately the center of the tips of the top flaps 16LF, 16RF to the ends on the front panel 11 side, and the tops of the vials stored in the box B3 are pressed down and held from above by the tips of the top flaps 16LF, 16RF.

[0089] Even in this way, it is possible to obtain the same effect as in the second embodiment (excluding the effect of the buffer functional part on the bottom lid side). In particular, in the case of this box B3, since each pressing piece 221 extends from the center of the tip of each upper flap 16LF, 16RF to the end on the front plate 11 side, when the vial is stored in box B3 closer to the front plate 11 side than the center of box B3, each pressing piece 221 can reliably press down the upper surface of the upper part of the vial.

[0090] In the case of this box B3, when closing the canopy 16 after it has been opened, as in the second embodiment, the upper flaps 16LF, 16RF of the canopy 16 are pushed toward the top opening of box B3 with the thumb or index finger, the top cover 16C is pushed down onto the top opening of box B3 with the thumb, and the insertion piece 16C1 of the top cover 16C is inserted inside the front panel 11, thereby closing the canopy 16 and resealing it.

[0091] The fourth embodiment is shown in Fig. 18 to Fig. 21. Fig. 18 shows the overall configuration of the packaging box with a cushioning function, and Fig. 19 shows the configuration of the main parts of the packaging box. Fig. 20 shows the configuration of the blank sheet before the packaging box is assembled. In this packaging box, a part of the configuration of the four side panels, a part of the configuration of the cushioning function part on the top side, and the configuration of the bottom cover and the cushioning function part on the bottom cover side are different from those of the first embodiment. Therefore, in the explanation of this embodiment, the same symbols are used for the configurations common to the first embodiment and the duplicated explanations are omitted, and only the different configurations are explained by using new symbols.

[0092] As shown in Figures 18 and 20, in the packaging box B4 with a cushioning function (hereinafter simply referred to as packaging box B4 or box B4), the arrangement of the four side panels 11-14 is slightly different from that of the first embodiment, and in this case, the front panel 11 is disposed on one side to the right of the four side panels 11-14. This is the only difference, and the size and shape of each side panel 11-14 are the same as those of the first embodiment.

[0093] As shown in Figures 19 and 20, in the case of this box B4, each pressing piece 221 is separated by a roughly U-shaped cut line 220, part of which straddles the extension plate 21, at one end side of each of the pressing plates 22 on the aforementioned intersection point X side, in other words, between one end side of each of the hypotenuses of each of the extension plates 21 on the intersection point X side and one end side of each of the hypotenuses of each of the upper flaps 16LF, 16RF on the intersection point X side, and is formed into a roughly rectangular shape continuing to the hypotenuses of each of the upper flaps 16LF, 16RF, i.e., (part of) the tip of each of the upper flaps 16LF, 16RF. More specifically, each of these cut lines 220 has an outer end, as viewed from each intersection point X, at the end opposite to the end on the hypotenuse of each upper flap 16LF, 16RF at each intersection point X, and an inner end at the middle (approximately the center) on the hypotenuse of each extension plate 21, forming a relatively long, approximately U-shaped shape overall, and extends from the other end of this cut line 220 slightly away from the hypotenuse of each extension plate 21 to a position slightly toward the other end side of each intersection point X side of each left and right side edge of the top cover 16C, and is formed from there along each left and right side edge of the top cover 16C to each intersection point X. In this way, each pressing piece 221 extends from the center of the tip of each upper flap 16LF, 16RF toward the back panel 13.

[0094] 20, the bottom cover 5 includes a front panel-side bottom plate 51 and a rear panel-side bottom plate 52 extending from the front panel 11 and the rear panel 13 via fold lines L12 and L13, respectively, and a left lower flap 53 and a right lower flap 54 extending from the left panel 14 and the right panel 12 via fold lines L14 and L15 and having adhesive pieces 531 and 541 adhesively fixed to the front panel-side and rear panel-side bottom plates 51 and 52, respectively. In this case, the front panel-side bottom plate 51 is formed in a substantially T-shape in plan view. A lock claw 511 is also provided at the tip (lower end) of the front panel-side bottom plate 51 at the corner on the left panel 14 side, protruding toward the left panel 14. The bottom plate 52 on the rear plate side is formed at the rear plate side end (part of the composite plate 52S) of the composite plate 52S extending from the lower edge of the rear plate 13, into a substantially trapezoidal shape with the lower edge of the rear plate 13 as the bottom base. The left and right lower flaps 53, 54 are formed at the lower edges of the left side plate 14 and the right side plate 12 into a substantially trapezoidal shape with the lower edges of these plates as the bottom base. In the left lower flap 53, an adhesive piece 531 is formed extending vertically from the oblique side on the front plate 11 side in a substantially rectangular shape, and in the right lower flap 54, an adhesive piece 541 is formed extending vertically from the oblique side on the rear plate 13 side in a substantially rectangular shape. Note that folding lines 530, 540 are provided between the left and right lower flaps 53, 54 and the adhesive pieces 531, 541. Thus, the left lower flap 53 is adhesively fixed to the outer surface of the bottom plate 51 on the front panel side via an adhesive piece 531, and the right lower flap 54 is adhesively fixed to the outer surface of the bottom plate 52 on the rear panel side via an adhesive piece 541.

[0095] The bottom cover side buffer function section 6 is formed in the remaining part of the composite plate 52S extending from the lower edge of the back plate 13. In this case, the composite plate 52S has a substantially rectangular rising section 61 which is raised continuously from the tip (lower end) of the bottom plate 52 on the back plate side and has a substantially rectangular opening 610 in the height direction from the bottom plate 52 on the back plate side, a substantially square flat section 62 which extends continuously from the rising section 61 toward the back plate 13 and has a substantially annular opening 620 cut out in a substantially circular ring shape via a tapered opening 6201 which is continuous with the opening 610 of the rising section 61, and a substantially rectangular fixing section 63 which is continuous with the flat section 62 and is adhesively fixed to the inner surface of the back plate 13. In this case, the opening 610 of the rising section 61 is cut out in a substantially rectangular shape so that a vial can be inserted therethrough, and the substantially annular opening 620 of the flat section 62 is formed in a substantially arc shape so that it can be engaged along the body of the vial.

[0096] Thus, the box B4 is folded flat as described above. Then, in the vial packaging process, the box is erected into a box shape, and the vials are stored in the buffer functional portion 6 on the bottom cover side through the top opening of the box B4. After the vials are stored, the top opening is closed by the lid 16.

[0097] That is, when the top cover 16C is folded up to the top opening of the box B4 together with the extension plates 21 to close the top opening, the pushing plates 22 push the tips of the top flaps 16LF, 16RF below the top opening, and the entire top flaps 16LF, 16RF are pushed down diagonally into the box B4, as shown in Fig. 19. As a result, the upper surfaces of the upper parts of the vials stored in the box B4 are pressed down by the pushing pieces 221 extending from the center of the tips of the top flaps 16LF, 16RF toward the back plate 13, as shown in Fig. 21, and the tops of the vials stored in the box are pressed down and held from above by the tips of the top flaps 16LF, 16RF.

[0098] Even in this case, the same effect as in the second embodiment can be obtained. In particular, in the case of this box B4, since each pressing piece 221 extends from the center of the tip of each upper flap 16LF, 16RF toward the rear panel 13, when the vial is stored in the box B4 closer to the rear panel 13 side than the center of the box B4, each pressing piece 221 can reliably press down the upper surface of the upper part of the vial.

[0099] In the case of box B4, when closing the canopy 16 after it has been opened, as in the second embodiment, the canopy 16 is closed and resealed by pushing each upper flap 16LF, 16RF of the canopy 16 toward the top opening of box B4 with the thumb or index finger, and then pushing the top cover 16C down onto the top opening of box B4 with the thumb, and inserting the insertion piece 16C1 of the top cover 16C into the inside of the front panel 11.

[0100] In each of the above embodiments, the pair of extension plates and the pair of upper flaps are each formed in an approximately trapezoidal shape (excluding the pair of upper flaps in the third embodiment), but these extension plates and upper flaps may each be formed in an approximately triangular shape instead of an approximately trapezoidal shape. Even in this case, the same effects as those of the above-described embodiments can be achieved.

[0101] In each of the above embodiments, each pressing piece is formed into an approximately rectangular or approximately triangular shape continuing from a portion of each upper flap by separating a portion of each pressing plate by an approximately C-shaped or straight cut line that crosses over the extension plate, but each pressing piece may be formed into an approximately semi-oval, approximately triangular or approximately semicircular shape continuing from a portion of each upper flap by separating a portion of each pressing plate by an approximately U-shaped, approximately V-shaped or approximately C-shaped cut line that crosses over the extension plate. Even in this case, the same effects as those of the above-described embodiments can be achieved.

[0102] In addition, in each of the above embodiments, the cushioning function part on the top cover side is naturally provided on both sides of the top cover of the top cover, but this cushioning function part may be provided on both sides of the bottom cover bottom cover, or on both sides of the top cover of the top cover, or on both sides of the bottom cover bottom cover, instead of the cushioning function part on the bottom cover side described above. In this case, it is preferable when packaging a medicine pack (a plurality of tablets or capsules stored in a single PTP sheet, and this PTP sheet is further pillow-packaged in units of multiple sheets or bound with a cable tie to form a bundle), etc. Specific examples are shown in Figures 22 and 23.

[0103] 22 and 23, the four side panels 11-14, the canopy 16, and the canopy-side cushioning function section 2 are the same as in the first embodiment, and in this case, the bottom lid 16D and the bottom lid-side cushioning function section 2D are formed symmetrically with the canopy 16 and the canopy-side cushioning function section 2. Note that the box in Fig. 22 is a three-flap type, while the box in Fig. 23 is a four-flap type, with the box in Fig. 22 having no flaps above or below the front panel, and the box in Fig. 23 having inner lids above and below the back panel and outer lids above and below the front panel, and these are the points in which the two differ. Thus, the medicine packs etc. stored in the box are held down from above and below by the upper and lower flaps on the top and bottom lid sides. By doing so, it is possible to achieve the same or greater effects as those of the above-described embodiments with respect to the pharmaceutical packs in the box. The box of the third embodiment can be applied to packaging of medicine packs and the like in the same configuration, not limited to packaging of vials, and can achieve the same effects. Also, in this case, the bottom lid and the buffer functional part on the bottom lid side may be formed symmetrically with the canopy and the buffer functional part on the canopy side, and even in this case, the medicine packs stored in the box can be pressed and held from above and below by the upper and lower flaps on the canopy side and the bottom lid side, and the same effects as those of the above embodiments can be achieved for the medicine packs in the box.

[0104] Furthermore, although in each of the above embodiments, the canopy 16 is in the form of three flaps, it may also be in the form of four flaps, i.e., having a pair of upper flaps formed respectively connected to the upper ends of two of the four side panels that face each other, and an outer lid and an inner lid formed respectively connected to the upper ends of two other side panels other than the two side panels, and even in such a four-flap form, the cushioning function section 2 can be similarly provided on the canopy (inner lid). Even in this case, the same effects as those of the above-described embodiments can be achieved.

[0105] Furthermore, in the above embodiments, the boxes are exemplified as boxes for packaging vials, drug packs, etc., but the boxes may be used to package various items other than vials and drug packs. Similar effects can be achieved with respect to various other items. [Explanation of symbols]
