Description

The present invention relates to a packaging box for storing medicines that is suitable for managing the remaining quantity.

Packaging boxes for storing medicines such as tablets and capsules are known. These packaging boxes are made of a paper sheet formed into a hexahedron.

Utility Model Registration No. 3216555

For example, multiple tablets are stored in multiple pockets of a single PTP sheet. Then, multiple PTP sheets are stored in a storage bag to form a single drug bundle. Then, multiple drug bundles are stored in a single packaging box. When used, the packaging box is opened, and one drug bundle is removed from the packaging box and stored in a specified storage position. The remaining drug bundles are placed on a shelf or the like while still stored in the packaging box.

In drug inventory management, it is desirable to be able to easily grasp the number of remaining drug bundles contained in a packaging box placed on a shelf. For example, it is tedious to write the number of remaining drug bundles with a pen or the like on the outer surface of the packaging box or the outer surface of the flap, and then to correct and rewrite the written number of remaining drug bundles every time a drug bundle is taken out of the packaging box. In addition, the remaining number and strikeouts are written on the outer surface of the packaging box, making it difficult to understand at a glance. In addition, writing on the flap, which has a relatively small area compared to the outer surface, is also tedious and difficult to see. On the other hand, if the area of the flap is large, space is required around the packaging box to allow the flap to stand up, and the space required to store the packaging box becomes larger.

The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide a means for easily managing the number of drug bundles remaining in a packaging box.

(1) The packaging box according to the present invention stores multiple drug bundles in which multiple drugs of the same dosage form are divided into unit quantities. The packaging box includes an outer wall that defines an internal space in which the drug bundles are stored, the outer surface of which is visible from one direction, and a piece that constitutes the display wall and has at least a portion of its periphery that can be separated from the display wall to form an opening in the display wall. The number of pieces is at least one less than the number of drug bundles stored.

Each time a drug bundle is removed from the packaging box, the piece is separated from the display wall, forming openings in the display wall equal to the number of drug bundles removed. This allows the number of drug bundles remaining in the interior space to be ascertained at a glance at the display wall of the packaging box.

(2) Preferably, the plurality of pieces are arranged in a row on the display wall.

It is easy to see how many openings have been created by separating the pieces from the display wall.

(3) Preferably, the periphery of the piece has a first cutting line that allows the piece to be severed from the display wall, and a folding line that allows the piece to be folded relative to the display wall.

By pushing the piece against the display wall, the piece is cut from the display wall along the first cutting line, and the piece is folded against the display wall along the folding line. At this time, the piece does not separate from the display wall, so the piece does not become waste.

(4) Preferably, each of the folding lines of the multiple pieces extends along the same direction.

The multiple pieces are pushed into the display wall and folded in the same direction, making it easy to use.

(5) Preferably, the packaging box according to the present invention further has an inner wall located inside the display wall and covered by the display wall. The inner wall has a used marking in an exposed area exposed to the outside through the opening in the display wall, allowing the user to recognize that the drug bundle has been used.

When an operator turns over or tears off the opening piece, a used indication such as "used" appears. The used indication lets the operator know that the drug bundle has been used. In other words, the packaging box of the present invention lets the operator know that the number of drug bundles corresponding to the opening piece has already been used by turning over or tearing off the opening piece.

(6) Preferably, the display wall has an adjacent opening disposed adjacent to the piece.

The adjacent opening provided adjacent to the piece exposes the end surface of the piece to the outside. The worker places his or her finger on the exposed end surface and lifts the piece towards himself or herself. In other words, the adjacent opening makes it easier for the worker to lift the piece.

(7) Preferably, the end surface of the piece that faces the adjacent opening is a concave curved surface.

The end surface of the piece on which the worker places his or her finger is made into a concave curved surface that fits the finger, making it even easier for the worker to raise the piece.

(8) Preferably, the piece is located between the adjacent opening and the end of the display wall. The piece has a pair of first cutting lines each extending from the end on the adjacent opening side toward the end of the display wall.

The worker raises the piece towards himself while cutting the first cutting line. In other words, the first cutting line makes it easier for the worker to raise the piece towards himself.

(9) Preferably, the outer surface of the piece or the outer surface of the display wall around the piece is marked with a recognizable number corresponding to the number of drug bundles contained in the internal space.

The number of drug bundles contained in the internal space can be easily ascertained by the remaining markings on the outer surface of the piece that is not opened and forms part of the display wall, or on the outer surface of the display wall surrounding the piece.

(10) Preferably, the display wall further includes a drug display section surrounded by a second cutting line that can be separated from the display wall, and the outer surface of the drug display section has drug notation relating to the drug.

By separating the medication display section from the display wall, it can be used as medication labeling to indicate the medication in the storage area where the medication is taken out.

(11) Preferably, the packaging box is a rectangular parallelepiped whose left-right dimension is shorter than its up-down and front-back dimensions. The outer surface of the display wall is one of two surfaces extending along the up-down and left-right directions.

By placing multiple packaging boxes on a shelf so that the outer surface of the display wall with the smallest area faces the worker, more of the display walls of the multiple packaging boxes placed on the shelf can be directed toward the worker.

(12) Preferably, the packaging box includes a rectangular cylindrical body including four of the outer walls extending along the up-down direction, and an outer flap that extends from one of the four outer walls on the periphery of an upper opening that opens upward in the body and is capable of sealing the upper opening.

When the packaging box is placed on a shelf with the display wall facing the worker, the top opening faces upwards, so there is no risk of the medicine stored in the internal space unintentionally leaking out of the packaging box into the external space.

(13) Preferably, the container further includes an inner flap extending from the edge of an outer wall adjacent to the outer wall from which the outer flap extends, and the outer surface of the inner flap has an opening marking on it to indicate that the container has been opened.

After the packaging box has been opened, the inner flap is positioned outside the outer flap that seals the top opening, making it possible to identify that the packaging box has been opened by the opening markings on the inner flap.

(14) Preferably, a portion of the periphery of the opening mark is a fourth cut line that can be separated from the inner flap.

The opening label that is separated from the inner flap is smaller than the inner flap, so it is less likely to get in the way when storing the packaging box.

According to the present invention, the number of drug packets remaining in the interior space can be recognized at a glance by looking at the display wall of the packaging box.

A preferred embodiment of the present invention will be described below. Note that this embodiment is merely one embodiment of the present invention, and it goes without saying that the embodiment can be changed without changing the gist of the present invention. In the following description, the up-down direction 7 is defined based on the state in which the packaging box 10 is upright (the state shown in FIG. 1), the front-rear direction 8 is defined with the side on which the display wall 33 is provided as the near side (front), and the left-right direction 9 is defined when the packaging box 10 is viewed from the near side (front).

As shown in FIG. 2, the packaging box 10 accommodates five pillow-packaged medicine products 20 in the internal space 16. Each pillow-packaged medicine 20 accommodates, for example, ten PTP sheets 21 (see FIG. 6) in which ten tablets 22 are enclosed in two columns and five rows. The number of tablets 22 accommodated in each pillow-packaged medicine 20 is the same. The pillow-packaged medicine 20 is an example of a medicine bundle. The tablets 22 are an example of a dosage form.

The number of pillow-packaged products 20 that can be accommodated in the packaging box 10, the number of tablets 22 accommodated in one pillow-packaged product 20, and the number of tablets 22 accommodated in one PTP sheet 21 may be changed as appropriate. Furthermore, tablets 22 are merely one example of a drug dosage form, and various drug dosage forms may be adopted, such as a powder sealed in a bag or a liquid sealed in a container.

The packaging box 10 is a rectangular parallelepiped whose dimension in the left-right direction 9 is shorter than its dimensions in the up-down direction 7 and front-back direction 8. The dimension in the up-down direction 7 of the packaging box 10 is shorter than its dimension in the front-back direction 8. For example, the dimension in the up-down direction 7 of the packaging box 10 is 125 mm, the dimension in the front-back direction 8 is 155 mm, and the dimension in the left-right direction 9 is 47 mm.

As shown in Figures 1, 2 and 4, the packaging box 10 has a body 11, an outer flap 12, an inner flap 13, a bottom wall 14 and an inner flap 15.

[Body 11]
1 to 3 , the body 11 divides an internal space 16 in the front-to-rear direction 8 and the left-to-right direction 9. In a cross section taken along the up-to-down direction 7 and the left-to-right direction 9, the internal space 16 has a dimension in the left-to-right direction 9 that is shorter than each of the dimensions in the up-to-down direction 7 and the front-to-rear direction 8. The body 11 has a rectangular cylindrical shape. The dimension of the body 11 in the up-to-down direction 7 is shorter than the dimension in the front-to-rear direction 8.

The body 11 has two outer walls 31, 32 that extend in the up-down direction 7 and the front-rear direction 8, and a display wall 33, an inner wall 37, and an outer wall 34 that extend in the up-down direction 7 and the left-right direction 9. The body 11 has an opening 35 that opens the internal space 16 upward, and an opening 36 (not shown) that opens the internal space 16 downward. Each opening 35, 36 is rectangular. Opening 35 is an example of an upper opening.

The outer walls 31 and 32 face each other in the left-right direction 9. The outer walls 31 and 32 have the same dimensions in the up-down direction 7 and the front-rear direction 8. The outer surface areas of the outer walls 31 and 32 are the same in the unopened state shown in FIG. 1.

The display wall 33 and the inner wall 37 overlap in close contact in the front-to-rear direction 8. The inner wall 37 and the outer wall 34 face each other in the front-to-rear direction 8. The display wall 33 and the outer wall 34 have the same dimensions in the up-down direction 7 and the left-right direction 9. Furthermore, the areas of the outer surfaces of the display wall 33 and the outer wall 34 are the same in the pre-opening state shown in FIG. 1. The outer surface 54 of the display wall 33 extends along the up-down direction 7 and the left-right direction 9. The outer surface 54 is visible from one direction, for example, from the front. The outer surface 54 is an example of the outer surface of a display wall.

As shown in Figures 1 to 4, outer wall 31 is located to the left of outer wall 32 and has an opening piece 41 and a cut-out piece 42.

The opening piece 41 is pushed in by an operator when one end of the outer flap 12 is separated from the outer wall 31 and the outer flap 12 is raised to open the package. The opening piece 41 is located at the upper end of the center of the outer wall 31 in the front-to-rear direction 8. The opening piece 41 is approximately rectangular on the outer surface of the outer wall 31 and has an area about the size of the tip of a person's thumb. The periphery of the opening piece 41 is formed by a cutting line 43. The periphery of the upper end of the opening piece 41 is connected to the first base 12A described below. The cutting line 43 is a so-called perforation, and is a linear series of intermittent cuts. The same applies to each subsequent cutting line. The cutting line 43 is formed in two layers along the front-to-rear direction 8 at the lower end of the opening piece 41, and the lower cut of the two layers is anchor-shaped.

The cut-out piece 42 is pressed in when the drug display section 70, which will be described later, is cut from the display wall 33. The cut-out piece 42 is located at the front end of the center of the outer wall 31 in the up-down direction 7. The cut-out piece 42 has a semicircular shape that arches backward on the outer surface of the outer wall 31, and has an area about the same as the tip of a person's thumb. The cut-out piece 42 has an inner periphery on the outer surface of the outer wall 31 formed by a cut line 44. The right end periphery of the cut-out piece 42 is connected to the drug display section 70 via a cut line 45.

The outer wall 32 is located to the right of the outer wall 31, and has an opening piece 46 as shown in FIG. 4. The opening piece 46 is pushed in when one end of the bottom wall 14 is lowered along the up-down direction 7 so as to move it away from the outer wall 32 and open it. The opening piece 46 is located at the lower end of the center of the outer wall 32 in the front-to-back direction 8. The opening piece 46 is a roughly semicircular shape that draws an upward arc on the outer surface of the outer wall 32, and has an area about the size of the tip of a person's thumb. The periphery of the opening piece 46 within the outer surface of the outer wall 32 is formed by a cut line 47. The periphery of the lower end of the opening piece 46 is connected to the third base 14A described below.

As shown in Figures 1 to 4, the display wall 33 and the inner wall 37 are located in front of the outer wall 34. The area of the display wall 33 in the up-down direction 7 and the left-right direction 9 is larger than the area of the inner wall 37 in the up-down direction 7 and the left-right direction 9 in the unopened state shown in Figure 1.

As shown in Figures 4 and 5, the inner wall 37 constitutes a part of the inner surface of the packaging box 10. The inner wall 37 extends from the front end of the outer wall 32. The inner wall 37 extends leftward from the outer wall 32 toward the outer wall 31. The dimension of the inner wall 37 in the up-down direction 7 is equal to the dimension of the outer wall 32, and the dimension in the left-right direction 9 is shorter than the dimension in the left-right direction 9 of the packaging box 10. The inner wall 37 is flat and has a roughly semicircular cutout 53 that forms an arc to the right at the left end of the center in the up-down direction 7.

As shown in Figures 1 to 4, the display wall 33 constitutes the outer wall of the packaging box 10. The display wall 33 extends from the front end of the outer wall 31. The display wall 33 extends rightward from the outer wall 31 toward the outer wall 32. The display wall 33 has a dimension in the up-down direction 7 equal to that of the outer wall 31, and a dimension in the left-right direction 9 equal to that of the packaging box 10. The display wall 33 has a flat plate shape. The display wall 33 overlaps in front of the inner wall 37, and is adhered to the inner wall 37 with an adhesive or the like.

[Opening piece 60]
The indicating wall 33 has an opening piece 60. The opening piece 60 is pushed into the internal space 16 of the packaging box 10 to form an opening 61 (see FIG. 3 ) in the indicating wall 33. The opening piece 60 is an example of a piece.

Four opening pieces 60 are located on the display wall 33. The four opening pieces 60 are arranged in a row at equal intervals along the up-down direction 7 to the right of the center in the left-right direction 9 of the display wall 33. Each opening piece 60 constitutes a part of the display wall 33. The number of opening pieces 60 is one less than the number of pillow-packaged products 20 contained in the internal space 16. Each opening piece 60 has a periphery 62 on the outer surface 54 that is approximately rectangular with the two left corners rounded, and has an area about the size of the tip of a person's thumb. Each opening piece 60 has approximately the same dimensions in the up-down direction 7 and the left-right direction 9.

The opening piece 60 has a cutting line 62A that can be cut off from the display wall 33, and a folding line 62B that can be folded relative to the display wall 33. The cutting lines 62A are the upper, left, and lower sides of the periphery 62. The folding line 62B is the right side of the periphery 62. The folding lines 62B of the four opening pieces 60 extend along the up-down direction 7 and are aligned in a straight line. The cutting line 62A is an example of a first cutting line.

The opening 61 is formed in the display wall 33 by cutting the opening piece 60 from the display wall 33 along the cutting line 62A and folding it along the folding line 62B into the internal space 16. The opening 61 communicates with an opening 66, which will be described later, and the communicating opening penetrates the body 11 from the external space to the internal space 16.

[Opening piece 65]
The inner wall 37 has an opening piece 65. The opening piece 65 is pushed into the internal space 16 of the packaging box 10 together with the opening piece 60, thereby forming an opening 66 (see FIG. 3) in the inner wall 37.

Four opening pieces 65 are located on the inner wall 37. The four opening pieces 65 are lined up in a row at equal intervals along the up-down direction 7 to the right of the center in the left-right direction 9 of the inner wall 37, and their positions in the up-down direction 7 and left-right direction 9 coincide with those of the four opening pieces 60. Each opening piece 65 constitutes a part of the inner wall 37. The number of opening pieces 65 is the same as the number of opening pieces 60. Each opening piece 65 has a periphery 67 in the up-down direction 7 and left-right direction 9 that is approximately rectangular with the two left corners rounded, and has an area about the size of the tip of a person's thumb. Each opening piece 65 has approximately the same dimensions in the up-down direction 7 and left-right direction 9.

The opening piece 65 has a cutting line 67A that can be cut off from the inner wall 37, and a folding line 67B that can be folded relative to the inner wall 37. The cutting lines 67A are the upper, left, and lower edges of the periphery 67, and their positions in the up-down direction 7 and the left-right direction 9 coincide with the cutting line 62A. The folding line 67B is the right edge of the periphery 67, and their positions in the up-down direction 7 and the left-right direction 9 coincide with the folding line 62B. The folding lines 67B of the four opening pieces 65 extend along the up-down direction 7 and are aligned in a straight line.

The opening 66 is formed in the inner wall 37 by cutting the opening piece 65 from the inner wall 37 along the cutting line 67A and folding it into the internal space 16 along the folding line 67B.

[Remaining number display 55]
The display wall 33 has a remaining number display 55. The remaining number display 55 is an example of a remaining notation. The remaining number display 55 is intended to enable a worker to recognize the remaining number of pillow packaged products 20 and the like. The remaining number display 55 is printed on the outer surface of each opening piece 60 and below the opening piece 60 located at the bottom. The remaining number display 55 is printed in Arabic numerals "5,""4,""3,""2," and "1" from top to bottom.

[Drug display section 70]
The display wall 33 has a medicine display section 70 to the left of the remaining quantity display 55. On the outer surface of the medicine display section 70, any or all of information related to the medicine contained in the packaging box 10, such as the content, storage method, regulatory classification, serial number, expiration date, product name, manufacturer, content amount, bar code, etc., is displayed.

Two drug display sections 70 are located on the display wall 33. The two drug display sections 70 are arranged in a row along the up-down direction 7 with no gaps. Each drug display section 70 occupies an area from the center to the left end in the left-right direction 9 on the outer surface of the display wall 33. Each drug display section 70 has a roughly rectangular shape with rounded corners on the combined edges, and has, for example, a dimension of about 30 mm along the left-right direction 9 and a dimension of about 75 mm along the up-down direction 7. Each drug display section 70 has the same dimensions in the up-down direction 7 and the left-right direction 9.

The drug display section 70 is formed by a cutting line 45 around the periphery and between the two drug display sections 70. The left edge of the periphery of the drug display section 70 extending along the vertical direction 7 overlaps with the left end of the display wall 33. A portion of the left end of the drug display section 70 extending in the vertical direction 7 is connected to the cut-out piece 42 via the cutting line 45. The cutting line 45 is an example of a second cutting line.

On one outer surface of the drug display section 70, for example, a display frame 71 is displayed, and the content, storage method, regulatory classification, manufacturing number, and expiration date are displayed within the display frame 71. On the other outer surface of the drug display section 70, for example, the display frame 71 is not displayed, and the product name, manufacturer, content amount, and barcode are displayed.

[Outer flap 12]
The outer flap 12 is capable of changing its position relative to the body 11. The outer flap 12 changes its position between a closed position (see FIG. 1 ) in which the outer flap 12 seals an opening 35 at the top of the body 11 and an open position (see FIG. 2 ) in which the outer flap 12 exposes the opening 35. In the closed position, the outer flap 12 defines an internal space 16.

As shown in Figures 2 and 4, the outer flap 12 has a first base portion 12A, an insertion portion 12B, and a second base portion 12C.

The first base 12A defines the internal space 16 in the outer flap 12 in the closed position. The first base 12A extends from the periphery of the opening 35. In the closed position, the first base 12A extends leftward from the outer wall 32 toward the outer wall 31. In the closed position, the first base 12A has a dimension in the front-to-rear direction 8 equal to the dimension in the front-to-rear direction 8 of the opening 35, and a dimension in the left-to-right direction 9 equal to the dimension in the left-to-right direction 9 of the opening 35. The first base 12A has a flat plate shape. At the end of the first base 12A extending from the outer wall 32 (facing left), the first base 12A is connected to the insertion portion 12B via a foldable fold line 75.

The insertion portion 12B is inserted into the internal space 16 when the outer flap 12 is in the closed position. The dimension of the insertion portion 12B in the front-to-rear direction 8 in the closed position is equal to that of the first base portion 12A, and the dimension in the up-down direction 7 is shorter than that of the outer wall 31.

The fold line 75 allows the insertion portion 12B to be folded toward the inner surface of the first base portion 12A, i.e., in a mountain fold, relative to the first base portion 12A. As shown in FIG. 4, the fold line 75 is located at the boundary between the first base portion 12A and the insertion portion 12B.

The second base 12C constitutes part of the outer surface of the packaging box 10 when the outer flap 12 is in the closed position. The second base 12C extends from the periphery of the opening 35 via a detachable cutting line 76. In the closed position, the second base 12C extends rightward from the outer wall 31 toward the outer wall 32. In the closed position, the dimension of the second base 12C in the front-to-rear direction 8 is approximately the same as the dimension of the opening 35 in the front-to-rear direction 8, and the dimension of the second base 12C in the left-to-right direction 9 is shorter than the dimension of the opening 35 in the left-to-right direction 9. In the closed position, the second base 12C overlaps the first base 12A, and is bonded to the first base 12A with an adhesive or the like.

The cutting line 76 is a line that allows the second base portion 12C to be separated from the outer wall 31. As shown in FIG. 4, the cutting line 76 is located at the boundary between the outer wall 31 and the second base portion 12C.

[Inner flap 13]
The inner flap 13 is located closer to the internal space 16 than the outer flap 12 when the outer flap 12 is in the closed position. The inner flap 13 supports the outer flap 12 so that the outer flap 12 in the closed position does not move beyond the periphery of the opening 35 toward the internal space 16.

As shown in Figures 2 and 4, the inner flap 13 has an inner flap 13A that extends from the display wall 33 on the periphery of the opening 35, and an inner flap 13B that extends from the outer wall 34 on the periphery of the opening 35.

The inner flap 13A supports the front end of the outer flap 12 when the outer flap 12 is in the closed position. In the closed position, the inner flap 13A extends rearward from the display wall 33 toward the outer wall 34. In the closed position, the left-right dimension of the inner flap 13A is equal to the left-right dimension 9 of the opening 35, and the front-rear dimension 8 is less than half the front-rear dimension 8 of the opening 35.

The inner flap 13A has an opening indicator 80. The opening indicator 80 is exposed to the outside of the outer flap 12 in the closed position, allowing the user to recognize that the packaging box 10 has been opened.

The opening indication section 80 is located at the lower end of the center of the inner flap 13A in the left-right direction 9. The opening indication section 80 constitutes part of the inner flap 13A. The opening indication section 80 is substantially rectangular on the outer surface of the inner flap 13A, and, for example, in the closed position, the dimension in the left-right direction 9 is approximately 25 mm, and the dimension in the front-rear direction 8 is approximately 15 mm.

In the opening indication section 80, "Opened" is printed on the outer surface of the inner flap 13A. As shown in FIG. 4, the periphery of the opening indication section 80 is formed by a cutting line 81 except for the periphery of the opening 35, and the portion that overlaps with the periphery of the opening 35 is formed by a folding line 82. The periphery of the medication indication section 70 formed by the cutting line 81 can be separated from the inner flap 13A. The printed characters "Opened" are an example of an opening indication. The cutting line 81 is an example of a fourth cutting line.

The inner flap 13B supports the rear end of the outer flap 12 in the closed position. In the closed position, the inner flap 13B extends rearward from the outer wall 34 toward the display wall 33. In the closed position, the left-right dimension of the inner flap 13B is equal to the left-right dimension 9 of the opening 35, and the front-to-rear dimension 8 is less than half the front-to-rear dimension 8 of the opening 35.

[Bottom wall 14]
The bottom wall 14 seals a lower opening 36 of the body 11. The bottom wall 14 divides the internal space 16 in the up-down direction 7. As shown in Fig. 4, the bottom wall 14 has a third base portion 14A and a fourth base portion 14B.

The third base 14A constitutes part of the inner surface of the packaging box 10. The third base 14A extends from the outer wall 32 on the periphery of the opening 36 below the body 11. The third base 14A extends leftward from the outer wall 32 toward the outer wall 31. The third base 14A has a dimension in the front-to-rear direction 8 equal to the dimension in the front-to-rear direction 8 of the opening, and a dimension in the left-to-right direction 9 equal to the dimension in the left-to-right direction 9 of the opening. The third base 14A is flat.

The fourth base 14B constitutes part of the outer surface of the packaging box 10. The fourth base 14B extends from the outer wall 31 on the periphery of the opening 36 below the body 11. The fourth base 14B extends rightward from the outer wall 31 toward the outer wall 32. The dimension of the fourth base 14B in the front-to-rear direction 8 is approximately the same as the dimension of the opening in the front-to-rear direction 8, and the dimension in the left-to-right direction 9 is shorter than the dimension of the opening 35 in the left-to-right direction 9. The fourth base 14B overlaps under the third base 14A, and is adhered to the third base 14A with an adhesive or the like.

[Inner flap 15]
The inner flap 15 is located closer to the internal space 16 than the bottom wall 14, and supports the bottom wall 14 so that the bottom wall 14 does not move from the periphery of the opening below the body 11 toward the internal space 16. The inner flap 15 has an inner flap 15A extending from the inner wall 37 of the periphery of the opening, an inner flap 15B extending from the display wall 33, and an inner flap 15C extending from the outer wall 34. The inner flap 15A and the inner flap 15B support the front end of the bottom wall 14. The inner flap 15A and the inner flap 15B extend rearward from the inner wall 37 and the display wall 33 toward the outer wall 34. The dimension of the inner flap 15B in the left-right direction 9 is equal to the dimension of the opening in the left-right direction 9, and the dimension of the inner flap 15B in the front-rear direction 8 is equal to or less than half the dimension of the opening in the front-rear direction 8. The inner flap 15A has dimensions in the left-right direction 9 and the front-to-rear direction 8 that are shorter than those of the inner flap 15B. The inner flap 15C supports the rear end of the bottom wall 14. The inner flap 15C extends rearward from the outer wall 34 toward the display wall 33. The dimension of the inner flap 15C in the left-right direction 9 is equal to the dimension of the opening in the left-right direction 9, and the dimension of the inner flap 15C in the front-to-rear direction 8 is equal to or less than half the dimension of the opening in the front-to-rear direction 8.

[Assembly of the packaging box 10]
The packaging box 10 is formed by folding and gluing the sheet 30 shown in Fig. 4 as described below. The sheet 30 is a thin, flat sheet made of, for example, paper or resin, but there are no particular limitations on the material as long as it can be punched or folded into a desired shape and has the rigidity to maintain the shape and the elasticity to adequately cushion impacts.

The sheet 30 is folded so that the inner wall 37 overlaps the display wall 33 on the inside at the folding line 85 located at the boundary between the inner wall 37 and the outer wall 32, the folding line 86 located at the boundary between the outer wall 32 and the outer wall 34, the folding line 87 located at the boundary between the outer wall 34 and the outer wall 31, and the folding line 88 located at the boundary between the outer wall 31 and the display wall 33, as shown in FIG. 4. The outer surface of the inner wall 37 and the inner surface of the display wall 33 are bonded with an adhesive or the like to form the body 11. At this time, the cutting line 67A of the opening piece 65 provided on the inner wall 37 and the cutting line 62A of the opening piece 60 provided on the display wall 33 are bonded so as to align with each other.

The sheet 30 is folded toward the interior space 16 at folding lines 89 and 90 located at the boundaries between the inner wall 37 and the inner flap 15A, and between the display wall 33 and the inner flap 15B. The sheet 30 is folded toward the interior space 16 at folding line 91 located at the boundary between the outer wall 34 and the inner flap 15C.

At a folding line 92 located at the boundary between the outer wall 32 and the third base 14A, the sheet 30 is folded toward the interior space 16 with the inner flap 15 on the inside. At a folding line 93 located at the boundary between the outer wall 31 and the fourth base 14B, the sheet 30 is folded so that the fourth base 14B overlaps the third base 14A. The outer surface of the third base 14A and the inner surface of the fourth base 14B of the sheet 30 are bonded with an adhesive or the like, and the opening 36 below the body 11 is sealed.

The sheet 30 is folded such that the inner flap 13 is folded toward the interior space 16 at the folding lines 82 and 94 located at the boundaries between the inner flap 13 and the display wall 33 and the outer wall 34.

At folding lines 95 and 75 located at the boundaries between the first base 12A and the outer wall 32 and between the insertion portion 12B and the first base 12A, respectively, the first base 12A and the insertion portion 12B are folded inwardly. At cutting line 76 located at the boundary between the second base 12C and the outer wall 31, the sheet 30 is folded so that the second base 12C overlaps with the first base 12A. The sheet 30 is bonded by adhesive or the like between the outer surface of the first base 12A and the inner surface of the second base 12C, and the opening 35 above the body 11 is sealed.

[Example of use of packaging box 10]
A packaging box 10 containing five pillow-packaged products 20 is stored with, for example, the bottom wall 14 abutting against a placement surface such as a shelf, as shown in Fig. 1. The packaging box 10 is placed on top of other packaging boxes for medicines placed on a shelf, or side-by-side with other packaging boxes. The packaging box 10 is placed on a shelf, etc., with the outer surface 54 of the display wall 33 facing the worker, so that the area of the surface facing the worker is as small as possible.

When opening the packaging box 10, the worker pushes in the opening piece 41, which is part of the outer wall 31, and separates the second base 12C from the outer wall 31 along the cutting line 76, causing the outer flap 12 to stand up along the folding line 95. As shown in FIG. 2, the position of the outer flap 12 of the packaging box 10 is changed, exposing the opening 35 of the body 11 and opening the internal space 16 upward. In this way, the pillow-packaged item 20 contained in the packaging box 10 can be removed.

After the packaging box 10 is opened, the opening indication section 80 can be separated from the inner flap 13A along the cutting line 81 and raised up in the vertical direction 7 before the opening 35 is sealed again by the outer flap 12. By raising the opening indication section 80, after the opening 35 is sealed again by the outer flap 12, the opening indication section 80 is not covered by the outer flap 12 and the "Opened" notation is exposed and visible from the outside.

After the packaging box 10 is opened and one pillow-packaged product 20 is taken out, the worker pushes the topmost opening piece 60 corresponding to the number "5" printed on the remaining number display 55 into the internal space 16. This forms one opening 61 in the display wall 33, and the number "5" printed on the remaining number display 55 does not appear on the outer surface 54 of the display wall 33. Similarly, the worker pushes in the opening piece 60 each time a pillow-packaged product 20 is subsequently taken out of the packaging box 10, or pushes in the number of opening pieces 60 corresponding to the number of pillow-packaged products 20 taken out. Therefore, the opening pieces 60 corresponding to the number of pillow-packaged products 20 taken out of the packaging box 10 are pushed toward the internal space 16 against the display wall 33, and the openings 61 corresponding to the number of pillow-packaged products 20 taken out are formed in the display wall 33. Then, after the last pillow-packaged product 20 is taken out of the packaging box 10, the packaging box 10 is discarded. In addition, as the opening piece 60 is pushed into the internal space 16, the opening piece 65 is pushed into the internal space 16, forming an opening 66 in the inner wall 37. The opening 61 and the opening 66 communicate with each other, and the communicating opening penetrates the packaging box 10 from the external space to the internal space 16.

[Effects of this embodiment]
Each time a pillow-packaged item 20 is removed from the packaging box 10, the opening pieces 60, 65 are separated from the indicating wall 33 and the inner wall 37, thereby forming openings in the indicating wall 33 and the inner wall 37 that communicate between the external space and the internal space 16 and the number of pillow-packaged items 20 that are equal to the number of pillow-packaged items 20 removed. This makes it possible to recognize the number of pillow-packaged items 20 remaining in the internal space 16 at a glance of the indicating wall 33 of the packaging box 10.

The four opening pieces 60, 65 are arranged in a row at equal intervals along the vertical direction 7, making it easy to grasp the number of openings formed by separating the opening pieces 60, 65 from the display wall 33 and the inner wall 37.

When the opening piece 60 is pressed against the display wall 33, the opening piece 60 is cut off from the display wall 33 along the cutting line 62A, and the opening piece 60 is folded against the display wall 33 along the folding line 62B. When the opening piece 65 is pressed against the inner wall 37, the opening piece 65 is cut off from the inner wall 37 along the cutting line 67A, and the opening piece 65 is folded against the inner wall 37 along the folding line 67B. At this time, the opening pieces 60, 65 do not separate from the display wall 33 and the inner wall 37, so the opening pieces 60, 65 do not become waste.

The folding lines 62B, 67B of each opening piece 60, 65 extend along the vertical direction 7 and are aligned in a straight line, so that the multiple opening pieces 60, 65 are pressed against the display wall 33 and the inner wall 37 and folded in the same direction, providing good operability.

The remaining number indicator 55 on the outer surface of the opening piece 60, which is not opened and forms part of the indicator wall 33, makes it easy to know how many pillow-packaged items 20 are stored in the internal space 16.

By separating the drug display section 70 from the display wall 33, it can be used as a drug label to indicate the drug in the storage location of the removed drug.

When the opening piece 60 is pushed into the display wall 33, an opening is formed in the display wall 33, and the drug display section 70 may be separated from the display wall 33. Even in such a case, the display wall 33 is overlapped with the inner wall 37, and the drug display section 70 is not provided on the inner wall 37, so that the body 11 and the packaging box 10 can have the rigidity to maintain their shape and the elasticity to adequately cushion impacts.

By placing multiple packaging boxes 10 on a shelf so that the outer surface 54 of the display wall 33 with the smallest area faces the worker, more of the display walls 33 of the multiple packaging boxes 10 placed on the shelf can be directed toward the worker.

When the packaging box 10 is placed on a shelf with the display wall 33 facing the worker, the opening 35 faces upward, so there is no risk of the medicine stored in the internal space 16 unintentionally leaking out of the packaging box 10 into the external space.

After the packaging box 10 has been opened, the inner flap 13A is positioned outside the outer flap 12 that seals the opening 35, so that the opening indicator 80 on the inner flap 13A makes it possible to recognize that the packaging box 10 has been opened.

The opening indication section 80, which is separated from the inner flap 13A, is smaller than the inner flap 13A and is therefore less likely to interfere with storing the packaging box 10.

[Modification 1]
In the above embodiment, an example has been described in which the display wall 33 has the opening piece 60, the remaining quantity display 55, and the drug display section 70. However, the display wall 33 may further have the removal section 101. In the first modified example, an example of a packaging box 100 in which the display wall 133 also has the removal section 101 will be described. In the packaging box 100 according to the modified example, five pillow-packaged items 20 are contained in the internal space 16 so as to be stacked in the vertical direction 7.

The packaging box 100 is a rectangular parallelepiped whose dimension in the left-right direction 9 is shorter than its dimensions in the up-down direction 7 and front-back direction 8. The dimension in the front-back direction 8 of the packaging box 100 is shorter than its dimension in the up-down direction 7. The packaging box 10 has, for example, a dimension of 155 mm in the up-down direction 7, a dimension of 125 mm in the front-back direction 8, and a dimension of 47 mm in the left-right direction 9.

As shown in Figures 7 to 9, the body 111 of the packaging box 100 has a left outer wall 131 that extends along the up-down direction 7 and the front-rear direction 8, a front display wall 133 that extends along the up-down direction 7 and the left-right direction 9, and an inner wall 137 that is overlapped with the display wall 133. The outer wall 131 and the display wall 133 have a removal portion 101.

The removal section 101, together with the internal piece 104, is separated from the outer wall 131 and the display wall 133 to form a removal opening 102 through which the pillow-packaged items 20 contained in the internal space 16 can be removed one by one.

The removal section 101 has an outer piece 101A and an opening piece 101B. The outer piece 101A is located below the opening piece 60 and the drug display section 70, at the lower end of the display wall 133. The outer piece 101A forms part of the display wall 133. The outer piece 101A is rectangular, with a dimension in the left-right direction 9 equal to the dimension in the left-right direction 9 of the display wall 133, and a dimension in the up-down direction 7 that is greater than or equal to one-fifth and less than or equal to one-third of the dimension in the up-down direction 7 of the display wall 133.

The opening piece 101B is pushed into the internal space 16 in the same way that an operator's fingers or the like push the external piece 101A and the internal piece 104 from the internal space 16 to the outside when the external piece 101A and the internal piece 104 described below are separated from the display wall 133 and the inner wall 137. The opening piece 101B is provided below the front end of the outer wall 131, in a position adjacent to the external piece 101A at the center of the external piece 101A in the up-down direction 7. The opening piece 101B is connected to the external piece 101A via a cutting line 103 described below.

The removal section 101 is formed by a cutting line 103 between the periphery and the outer piece 101A and the opening piece 101B, with the left side extending along the vertical direction 7 overlapping with the left end of the display wall 133, the right side overlapping with the right ends of the display wall 133 and the inner wall 137, and the bottom side extending along the horizontal direction 9 overlapping with the bottom end of the display wall 133. The cutting line 103 is an example of a third cutting line.

The inner wall 137 has an inner piece 104. The inner piece 104 is separated from the inner wall 137 at the same time that the outer piece 101A is separated from the display wall 133. The inner piece 104 has a smaller area in the up-down direction 7 and the left-right direction 9 than the outer piece 101A, and is located within the range of the outer piece 101A in the up-down direction 7 and the left-right direction 9. The inner piece 104 is adhered to the outer piece 101A with an adhesive or the like.

[Effects of Modification Example 1]
By forming the removal opening 102 , the pillow-packaged product 20 can be removed from the internal space 16 without opening the opening 35 of the packaging box 100 .

After the pillow-packaged items 20 are removed from the removal opening 102, when the remaining pillow-packaged items 20 are moved downward into the internal space 16, there is no pillow-packaged item 20 in the position in the vertical direction 7 corresponding to the uppermost opening piece 60. Therefore, the opening piece 60 is easily pushed against the display wall 133.

[Modification 2]
In the above embodiment, an example has been described in which the opening pieces 60, 65 are folded along the folding line 62B and remain connected to the indicating wall 33 or the inner wall 37 when pushed into the internal space 16. However, the opening pieces 60, 65 may be separated from the indicating wall 33 and the inner wall 37. In the second modification, an example of a packaging box 200 in which the opening piece 265 is provided across the folding line 85 from the inner wall 237 to the outer wall 232 will be described.

As shown in Figures 10(A) and 10(B), the packaging box 200 has a display wall 233 with an opening piece 260, and an inner wall 237 and an outer wall 232 with an opening piece 265.

As shown in Figures 10(A) and 10(B), the opening piece 260 is cut away from the display wall 233 to form an opening 261. The entire periphery 262 of the opening piece 260 is formed by the cutting line 262A, and the periphery 262 extends to the right end of the display wall 233, so that the entire opening piece 260 is cut away from the display wall 233.

The opening piece 265 is cut off from the inner wall 237 and the outer wall 232 to form the opening 266. The opening 261 and the opening 266 are connected and penetrate the packaging box 200 from the external space to the internal space 16. The opening piece 265 is provided from the inner wall 237 to the outer wall 232 across the folding line 85. The entire periphery of the opening piece 265 is formed by the cutting line 267A, and the entire piece is cut off from the inner wall 237 and the outer wall 232.

[Effects of Modification 2]
The packaging box 200 is separated from the display wall 233 by pushing the opening piece 260 to the right rear, and the opening pieces 265 of the outer wall 232 are sequentially separated from the outer wall 232 from the front end side. This makes it possible to easily form an opening with a large area. In addition, the operator does not need to remove the fingers or the like that have pushed the opening pieces 260, 265, making the operation easy.

[Modification 3]
In the above embodiment, an example was described in which the opening pieces 60, 65 remain connected to the display wall 33 or the inner wall 37 when the openings 61, 66 are formed. In the above modified example 2, an example was described in which the opening pieces 260, 265 are separated from the display wall 233 or the inner wall 237 and the outer wall 232 when the openings 261, 266 are formed. However, the packaging box 10 may be provided with opening pieces 60, 65 that can be pushed into the internal space 16 to form the openings 61, 66, and at the same time, the opening piece 65 is not separated from the inner wall 37, and only the opening piece 60 is entirely separated from the display wall 33 to form only the opening 60. In modified example 3, an example of a packaging box 300 provided with opening pieces 360, 365 that can be pushed into the internal space 16 together with the opening piece 365 of the inner wall 337, or that can be entirely separated from the display wall 333 without the opening piece 365 will be described.

As shown in FIG. 11, the packaging box 300 has a display wall 333 with an opening piece 360 and an inner wall 337 with an opening piece 365.

The opening piece 360 forms an opening 361 by being pushed into the internal space 16 or by being cut off from the display wall 333. The entire periphery 362 of the opening piece 360 is formed by the cutting line 362A, and the periphery 362 extends to the right end of the display wall 333, so that the entire opening piece 360 can be cut off from the display wall 333. At this time, the opening 361 is an opening in the display wall 333, and the rear is separated from the internal space 16 by the opening piece 365.

The opening piece 360 has a fold line 362B that extends in the up-down direction 7 to the right of the center in the left-right direction 9. The opening piece 360, together with the opening piece 365, can be pushed into the internal space 16 by bending along the fold line 362B. At this time, the opening 361 communicates with an opening 366 described below, and the communicating opening penetrates the packaging box 300 from the external space to the internal space 16.

The opening piece 365 is pushed into the internal space 16 to form an opening 366 in the inner wall 337. The opening piece 365 has a cutting line 367A (not shown) that can be cut off from the inner wall 337, and a folding line 367B that can be folded relative to the inner wall 337. The cutting line 367A is the upper side, left side, and lower side of the periphery 367, and its position in the up-down direction 7 and the left-right direction 9 coincides with a part of the cutting line 362A. The folding line 367B is the right side of the periphery 367, and its position in the up-down direction 7 and the left-right direction 9 coincides with the folding line 362B.

The opening pieces 365 have a used indication 356. The indications 356 are intended to enable a worker to recognize the remaining pillow packaged products 20, etc., according to the number of exposed opening pieces 365. The indications 356 are exposed to the outside when the opening pieces 360 are individually separated from the indication wall 333. The indications 356 are located in the center of each opening piece 365 in the vertical direction 7 and horizontal direction 9. Each indication 356 has the kanji character "used" printed on it.

[Effects of Modification 3]
An operator can determine the number of pillow-packaged items 20 remaining in the internal space 16 by looking at the indicating wall 333 of the packaging box 300 either by pushing the opening piece 360 in or by separating it from the indicating wall 333.

Even if the opening pieces 365 are left on the inner wall 337 and the opening pieces 360 are separated from the display wall 333, the display 356 indicating that the opening pieces 365 have been used is exposed to the outside, making it easy to know the number of openings 361.

[Variation 4]
In the above embodiment, an example is described in which the opening piece 60 is pushed into the internal space 16 by the worker. In this modified example, an example is described in which the opening piece 60 is torn off by the worker. Note that configurations other than those described below are the same as the configurations described in the embodiment. Furthermore, the same reference numerals as in the embodiment are used for the same configurations as in the embodiment, and descriptions thereof will be omitted.

The packaging box 500 described in this modified example includes an opening piece 60 and an adjacent opening 97, as shown in FIG. 13. The adjacent opening 97 is adjacent to the opening piece 60. Note that "adjacent to the opening piece 60" means that the adjacent opening 97 is provided facing the end face of the opening piece 60 so as to expose the end face of the opening piece 60 to the outside. In other words, the adjacent opening 97 has the function of exposing the end face of the opening piece 60 to the outside so that a worker can hook his/her finger on the end face of the opening piece 60. In the example shown in FIG. 13, the adjacent opening 97 is located adjacent to the left side of the opening piece 60, exposing the left end face of the opening piece 60 to the outside.

The size of the adjacent opening 97 is such that a worker can insert a finger into the adjacent opening 97 and hook the finger on the left end of the opening piece 60. Specifically, the length of the adjacent opening 97 in the vertical direction 7 is longer than the length of the opening piece 60 in the vertical direction 7. In addition, the length of the adjacent opening 97 in the horizontal direction 9 is longer than the thickness of an average person's finger.

The exposed end surface of the opening piece 60, which is the left end surface in FIG. 13, is a concave curved surface. A "concave curved surface" means a surface that curves toward the inside of the opening piece 60 when the opening piece 60 is viewed from the front in FIG. 13. The curvature of the curved left end surface of the opening piece 60 is set to match, for example, the pad of a person's fingertip. In other words, the opening piece 60 fits the person's fingertip and abuts against the fingertip evenly.

The opening piece 60 has a pair of upper and lower cutting lines 62A, similar to the embodiment described above. The pair of cutting lines 62A are each provided from the end facing the adjacent opening 97 to the end 33A of the display wall 33. That is, when the worker cuts the cutting lines 62A, the opening piece 60 is torn off from the display wall 33, as shown in FIG. 14.

As shown in FIG. 13, the opening piece 60 has the numbers "500," "400," "300," and "200" printed on it as the remaining number indicator 55. The remaining number indicator 55 allows the worker to recognize the number of tablets 22 contained in the packaging box 500. When the opening piece 60 is torn off from the indicator wall 33, the remaining number indicator 55 becomes invisible to the worker. Also, when the opening piece 60 is torn off from the indicator wall 33, the worker can see a used indicator 98 (FIG. 14) indicating that the tablets have been used, instead of the remaining number indicator 55.

To explain in more detail, as shown in FIG. 14, the opening piece 60 is torn off from the display wall 33 to form an opening 61 in the display wall 33. An exposed area 99, which is a part of the inner wall 37 located inside the display wall 33, is exposed to the outside through the formed opening 61. The exposed area 99 has a used indication 98. That is, by torn off the opening piece 60 from the display wall 33, the used indication 98 is visible to the worker instead of the remaining number indication 55. In the illustrated example, the used indication 98 is printed with the word "used." The used indication 98 is an example of a used notation.

[Effects of Modification Example 4]
In this modified example, the opening piece 60 is torn off from the indication wall 33, so that the worker can visually confirm the used indication 98 instead of the remaining number indication 55. The worker recognizes the number of tablets 22 by visually checking the remaining number indication 55, and recognizes that the tablets 22 have been used by visually checking the used indication 98. Therefore, the packaging box 500 of this modified example can reliably allow the worker to recognize the remaining number of tablets 22 contained therein and that the tablets 22 have been used.

In addition, the adjacent opening 97 exposes the end face of the opening piece 60 to the outside, making it easier for the worker to tear off the opening piece 60.

In addition, because the end surface of the opening piece 60 on which the worker places his/her fingers is a concave curved surface, the worker's fingers come into contact evenly with the end surface of the opening piece 60. As a result, it becomes even easier for the worker to tear off the opening piece 60.

The pair of upper and lower cutting lines 62A are cut, and the opening piece 60 is torn off from the display wall 33. That is, the pair of upper and lower cutting lines 62A on the opening piece 60 can make it even easier for the worker to tear off the opening piece 60.

In this modified example, a pair of upper and lower cutting lines 62A extend to the end 33A of the display wall 33, and an example has been described in which the opening piece 60 is torn off from the display wall 33 by cutting the cutting lines 62A. However, the opening piece 60 may be rolled up from the display wall 33 as shown in FIG. 15. Specifically, the opening piece 60 has a pair of upper and lower cutting lines N62A and a folding line 62B. The pair of upper and lower cutting lines 62A extend from the left end facing the adjacent opening 97 to just before the end 33A of the display wall 33. The folding line 62B extends from the right end of one cutting line 62A to the right end of the other tip line 62A along the end 33A of the display wall 33. The worker cuts the cutting line 62A to roll up the opening piece 60, and folds the opening piece 60 at the folding line 62B.
