Description

TECHNICAL FIELD The present invention relates to pharmaceutical packaging.

Conventionally, various pharmaceutical products in tablet, pill, and granule types have been commercially available. Such pharmaceuticals are normally distributed in the market in the form of being housed in a bottle or the like, and further housed in a paper box as a product package.

In order to improve the convenience of the user, the paper box in which the bottle container is stored generally has a cut line on the top surface for opening the box when the product is first used. It is. For example, as shown in the perspective view of FIG. 7, this cut line is formed on the side wall and is formed at two points in the middle of the boundary between the side wall and the top surface (corner ridgeline) of the paper box. They are formed on the upper side wall cut line 100 and the corner ridge line 101 as a starting point and end point, respectively, and extend in opposite directions from both ends of the upper side wall cut line 100 and connect to each end of the corner ridge line 101. It is known to have a pair of upper corner score lines 102.

In addition, it is preferable for paper boxes to be configured so that they can be folded thinly or crushed into small pieces in order to reduce their volume when discarded, from the perspective of increasing user convenience. It has been considered to provide a cut line similar to the one formed on the top surface of the paper box at the bottom of the paper box.

However, in the case of pharmaceutical packaging products in which containers containing pharmaceuticals are housed in paper boxes, the problem is that the contents are heavy, so a cut line similar to the structure shown in Figure 7 is added to the bottom of the paper box. If this is done, there is a problem in that the score line part will break due to impact during transportation, and there is a high risk that the bottom part will be opened. Due to these problems, paper boxes for packaging containers containing pharmaceuticals have not yet been equipped with a bottom opening structure, and it is difficult to easily fold the paper boxes into a small size when disposing of them, making it difficult to use them. There was a problem that it was inconvenient for people.

Each bottom cut line portion 10 is similarly configured to include a plurality of cut portions cut in the thickness direction of the bottom portion 3 and a lug portion disposed between the cut portions. Note that the cut portion may be configured to penetrate through the side wall portion 2 and the bottom portion 3 in the thickness direction, or may be configured in a half-cut shape in which the cut portion is cut by a predetermined thickness.

In the form shown in FIGS. 1 and 3, the form of the lower opening piece 9 is a part 22a of the corner ridge line 22 that forms the boundary between the bottom part 3 and the back plate 32 (the part 22a of the corner part ridge line 22 that forms the boundary between the bottom part 3 and the side wall part 2). It is formed in the shape of an isosceles trapezoid with the lower base being the lower base. That is, the lower side wall cut line portion 8 that constitutes a part of the outline of the lower opening piece 9 includes an upper side portion 81 that is approximately parallel to a portion 22a of the corner ridgeline 22 formed by the bottom portion 3 and the back plate 32. It is configured as follows. In this upper side portion 81, it is preferable that at least two or more coverlet portions (upper side coverlet portions) are formed. Further, it is preferable that the ratio of the upper side coverlet part to the total length of the upper side part 81 is in the range of 10% or more and 50% or less, and more preferably in the range of 30% or more and 40% or less. This is more preferable from the viewpoint of obtaining good unsealability while increasing strength.

The form of the lower opening piece 9 is not limited to the isosceles trapezoid shape as described above, but the lower side wall cut line portion 8 may be formed in a U-shape, and the form of the lower opening piece 9 may be semicircular. It may be configured to have a shape. In this case, the substantially parallel upper side portion 81 refers to a portion whose tangent line is 45 degrees or less with respect to the bottom surface 22.

Such a paper box 1 is assembled into a rectangular parallelepiped shape as shown in FIG. 1 using, for example, a box forming sheet 30 shown in FIG. 4. The individual box forming sheet 30 is made of a single blank sheet such as cardboard, and includes a box main body part 30a which forms a rectangular parallelepiped shape (prismatic tube shape) in an assembled state, and a box main body part assembled into a rectangular tube shape. It includes a lid forming part 30b and a bottom forming part 30c for closing each opening (upper opening and lower opening) of 30a. As shown in FIG. 4, the box main body portion 30a includes a glue margin 31, a back plate 32, a first side plate 33, a front plate 34, and a second side plate 35 connected in this order.

The inner lid member 40 extends from one end edge of the front plate 34, and includes an inner lid piece 40a and a resealing piece 40b connected in this order. The inner cover piece 40a and the front plate 34 are separated by a bending line L5, and the inner cover piece 40a and the resealing piece 40b are separated by a bending line L6 extending in parallel. Note that the inner lid piece 40a shares a bending line L5 with the front plate 34, and is formed in a square shape. Further, both corners of the tip of the resealing piece 40b are formed in an arc shape.

The outer lid piece 41 is a member that forms the upper surface 4 of the paper box 1 when the individual box forming sheet 30 is assembled, and is formed into a square shape having approximately the same size as the inner lid piece 40a. has been done. This outer cover piece 41 extends from one end edge of the back plate 32 and is separated from the back plate 32 by a bending line L7. Note that the bending line L7 constitutes a corner ridgeline 21 formed by the upper surface portion 4 and the back plate 32 when the individual box forming sheet 30 is assembled.

The flaps 42 and 43 close a part of the upper opening of the box main body 30a assembled into a rectangular tube shape, and are the edges where the inner cover piece 40a and the outer cover piece 41 of the box main body 30a are connected, respectively. It extends from a different edge. Specifically, the flap 42 extends from one end edge of the first side plate 33 and is separated from the first side plate 33 by a bending line L8. The flap 43 extends from one end edge of the second side plate 35 and is separated from the second side plate 35 by a bending line L9.

The outer cover piece 41 is folded along the bending line L7 so as to overlap the surface of the inner cover piece 40a, and is attached to the surface of the inner cover piece 40a with an adhesive applied to the back surface. In this case, as shown in the schematic cross-sectional view of FIG. It is bent to be approximately perpendicular to the inner lid piece 40a, and inserted into the rectangular cylindrical box main body 30a through the gap formed between the edges of the flaps 42, 43 and the back plate 32.

As shown in FIG. 4, the bottom structure portion 30c includes an inner sole piece 51, an outer sole piece 52, and flaps 53, 54. The inner bottom piece 51 extends from the other end edge of the front plate 34 and is separated from the front plate 34 by a bending line L10. The inner sole piece 51 shares a bending line L10 with the front plate 34, and is formed into an isosceles trapezoid shape with the bending line L10 serving as the lower sole.

The outer bottom piece 52 is a member that forms the bottom part 3 of the paper box 1 when the individual box forming sheet 30 is assembled, and is formed into a square shape having approximately the same size as the inner lid piece 40a. ing. This outer sole piece 52 extends from the other end edge of the back plate 32 and is separated from the back plate 32 by a bending line L11. Note that the bending line L11 becomes a portion that constitutes a corner ridgeline 22 formed by the bottom surface portion 3 and the back plate 32 when the individual box forming sheet 30 is assembled.

The flap 33 extends from the other end edge of the first side plate 33 and is separated from the first side plate 33 by a bending line L12. The flap 34 extends from the other end edge of the second side plate 35 and is separated from the second side plate 35 by a bending line L13.

The outer sole piece 52 is folded along the bending line L11 so as to overlap the surface of the inner sole piece 51, and is attached to the surface of the inner sole piece 51 with an adhesive applied to the back surface. In this case, as shown in the schematic cross-sectional view of FIG. 5(b), the inner sole piece 51 is accommodated between the outer sole piece 52 and the flap 53 (54).

Here, an upper side wall cut line portion 5 is formed on one end side of the back plate 32 (on the outer lid piece 41 side), and the upper side wall cut line portion 5 has a starting end and an ending end at two points in the middle of the bending line L7. An area defined by the upper side wall cut line 5 and a portion L7a connecting two points in the middle of the bending line L7 constitutes the upper opening piece 6. This upper opening piece 6 is formed into an isosceles trapezoid shape with a lower base being a portion L7a connecting two points in the middle of the bending line L7. Further, the upper opening piece 6 is separated from the back plate 32 due to the breakage at the upper side wall cut line portion 5, and after being separated, the upper opening piece 6 is rotatable about the bending line L7 as a rotation axis.

Further, a pair of upper corner cut line parts 7, 7 are formed on the bend line L7, extending in opposite directions from both ends of the upper side wall cut line part 5 and connecting to the ends of the bend line L7. There is.

Further, on the other end side of the back plate 32 (on the outer bottom piece 52 side), a lower side wall cut line portion 8 is formed, the starting end and the ending end being at two points in the middle of the bending line L11. A region defined by the lower side wall cut line portion 8 and a portion L11a connecting two points in the middle of the bending line L11 constitutes the lower opening piece 9. This lower opening piece 9 is formed into an isosceles trapezoid shape with a lower base being a portion L11a connecting two points in the middle of the bending line L11. Further, the lower opening piece 9 is separated from the back plate 32 due to breakage at the lower side wall cut line portion 8, and after being separated, the lower opening piece 9 is rotatable about the bending line L11 as a rotation axis.

In addition, one end of the outer bottom piece 52 constituting the bottom part 3 of the paper box 1 is connected to both ends of the lower side wall cut line part 8, and the other end is connected to the periphery of the outer bottom piece 52. A pair of bottom score lines 10.10 are formed which connect to the bottom surface. More specifically, the other end of each bottom cut line portion 10, 10 is set on each side 52a, 52b of the outer sole piece 52 extending in a direction perpendicular to the bending line L11, and each bottom cut line The parts 10, 10 are configured to be spaced apart from each other in the direction in which the back plate 32 extends. Here, in a projection view from the top side of the paper box 1 with containers housed inside it, each of the bottom cut lines 10, 10 is such that it passes through the inner area of the bottom surface of the container housed inside. It is preferable that it be formed at a suitable position.

By assembling the individual box forming sheet 30 configured as described above, the paper individual box 1 according to the present invention can be formed. By separating along the cut lines 7, 7, the inner lid member 40 and the outer lid piece 41 function as an integrated opening lid, and the resealing piece 40b can be inserted inside the box body 10. Then, the opened paper box 1 can be closed again and further opened and closed repeatedly.

In addition, by separating the lower opening piece 9 of the back plate 32 along the lower side wall cut line 8 and the bottom cut line 10, 10, the inner bottom piece 51 and the outer bottom piece 52 can function as an integrated opening bottom. become. By adopting such an opening bottom configuration, the paper box 1 can be easily folded into a small size, and the convenience for the user when disposing of the paper box 1 can be improved.

In the paper carton box 1 according to the present invention, the opening bottom structure for opening the bottom part is, as described above, a part 22a of the boundary between the bottom part 3 and the side wall part 2, and a lower side wall connected to both ends of the part 22a. It is composed of a lower opening piece 9 divided by a cut line part 8 and a pair of bottom cut line parts 10.10 connected to both ends of the lower opening piece 9, respectively, and the pair of bottom cut line parts 10.10. are formed inside the surface of the bottom surface portion 3, and are configured to be spaced apart from each other from one end toward the other end. With this structure, even if a heavy container containing pharmaceuticals is packaged inside, the cut line at the bottom of the paper box 1 will not break due to impact during transportation. This makes it possible to effectively prevent the bottom of the box from being opened. In particular, such a pair of bottom cut line portions 10.10 extend not to the sides facing the bending line L11, but to each side 52a, 52b of the outer bottom piece 52 extending in a direction perpendicular to the bending line L11. By adopting a configuration in which each paper box 9 extends from both ends, it is possible to more effectively prevent the cut line portion at the bottom of the paper box 1 from breaking due to impact during transportation, and the bottom of the box from being opened. becomes possible.

To explain more specifically, the impact that occurs during transportation to the paper box 1 containing containers containing pharmaceuticals is mainly horizontal impact due to the horizontal shaking of the internal container, or vertical impact. Vertical shocks are assumed to occur when lifting or lowering or pitching, and the area that is most loaded by these shocks is the boundary between the side wall portion 2 and the bottom surface portion 3. In the present invention, since the structure is such that there is no cut line part parallel to the boundary between the side wall part 2 and the bottom part 3 (a cut line part having a similar structure to the upper corner cut line part 7 Even if the container collides with the side wall 2 during rolling or an impact is generated on the bottom during pitching, the side wall 2 and bottom 3 will receive a large load. This can prevent the paper box 1 from breaking at the boundary.

Further, in the present invention, a pair of bottom cut line parts 10.10 are formed inside the surface of the bottom part 3, and are configured to be spaced apart from each other as they go from one end side to the other end side. . With this configuration, it is possible to configure the length of the cut line portion to be longer than when the cut line portion is formed on the boundary between the side wall portion 2 and the bottom portion 3 (corresponding to the bending line L11). As a result, it is possible to increase the length of the sleeve portions arranged between the cut portions and the number of sleeve portions. In other words, it is possible to further increase the strength of the bottom score line portion 10, and even if an impact occurs on the bottom surface during pitching, the bottom score line portion 10 is effectively prevented from breaking due to the impact. This makes it possible to effectively prevent the cut line at the bottom of the paper box 1 from breaking due to impact during transportation and the bottom of the box from being opened.

Further, it is preferable to set the maximum height of the lower opening piece 9 from the bottom surface part 3 to 8 mm or more from the viewpoint of increasing the strength of the lower opening piece 9 (the strength of the lower side wall cut line part 8). In this regard, the inventor of the present invention conducted a test and confirmed its effectiveness, and the content and results of the test will be explained below.

First, as for the test contents, a set of 8 pharmaceutical packaging bodies in which prescribed pharmaceutical storage containers were housed and packaged in paper boxes 1 according to the present invention were prepared and bundled with tape. A method was adopted in which a set of eight bundled pharmaceutical packaging bodies was freely dropped from a height of 100 cm onto a floor surface covered with iron plates, and it was confirmed whether or not the lower opening piece 9 would break due to the impact. In addition, as shown in the schematic diagram of FIG. 6(a), the form of the pharmaceutical packaging set is such that four pharmaceutical packaging bodies 61 are arranged in a 2×2 arrangement in the lower row, and the remaining four pharmaceutical packaging bodies are arranged in the upper part. The packaging bodies 61 are arranged in a 2×2 arrangement. Furthermore, when dropping the pharmaceutical packaging set 60, as shown in FIG. I let it happen. The individual paper boxes 1 included in the pharmaceutical package set 60 are arranged so that the lower opening pieces 9 are all placed on the side shown by arrow A in FIG. 6(b). Further, each paper box 1 is formed by assembling individual box forming sheets 30 as shown in FIG.

The pharmaceutical packaging set to be subjected to the drop test is a paper box in which the bottom part 3 and the top part 4 have a square shape of 4.8 cm x 4.8 cm, and the height of the side wall part 2 is 8.1 cm. 1. Type A: 6 sets consisting of 8K bottle containers containing tablets (100 tablets), the bottom part 3 and the top part 4 having a square shape of 6.1 cm x 6.1 cm. Type B: 6 sets, consisting of a paper box 1 with a side wall 2 having a height of 12.1 cm, and tablets (280 tablets) stored in a 13K bottle container. Consisting of a paper box 1 with a top surface 4 having a square shape of 6.8 cm x 6.8 cm and a side wall 2 having a height of 15 cm, tablets (420 tablets) are stored in a dedicated bottle container. A total of 18 sets of 6 sets of C type were prepared. The weight of each pharmaceutical package included in the A-type to C-type pharmaceutical package set is 78 g for A type, 288 g for B type, and 489 g for C type. Note that the bottle container in which each tablet is stored has a circular bottom contour. Further, the paper box 1 is formed using coated cardboard having a strength of 350 g/m ² which is commonly used.

The pharmaceutical packaging set 60 as described above is configured such that the maximum height of the lower opening piece 9 of the paper box 1 from the bottom surface 3 differs for each set. The maximum height of the lower opening piece 9 from the bottom surface part 3 in each set was 3 mm, 5 mm, 8 mm, 10 mm, 15 mm, and 20 mm. In other words, for any set of A type, B type, and C type, a pharmaceutical packaging set is prepared in which the maximum height of the lower opening piece 9 from the bottom surface 3 is 3 mm, 5 mm, 8 mm, 10 mm, 15 mm, and 20 mm. , a drop test was conducted. As shown in FIGS. 1 and 3, each lower opening piece 9 is attached to a part of the corner ridgeline that forms the boundary between the bottom part 3 and the back plate 32 (a part of the boundary between the bottom part 3 and the side wall part 2). ) is formed into an isosceles trapezoid shape with a lower base. Here, the length of the portion corresponding to the lower base of the isosceles trapezoidal lower opening piece 9 is 25 mm, and the length of the upper base (upper side portion 81) is 18 mm. Further, the lower side wall cut line portion 8 forming a part of the outline of the lower opening piece 9 includes a plurality of cut portions cut in the thickness direction of the side wall portion 2 and a coverlet portion disposed between the cut portions. Configured with the necessary features. The length of the cut portion is 7.5 mm, and the length of the jumper portion is 3 mm.

Each pharmaceutical package set 60 configured as described above was dropped onto the floor from a height of 100 cm, and it was confirmed whether or not the lower opening piece 9 had broken. Table 1 shows the results. In Table 1, cases in which the lower opening piece 9 was broken are marked as x, and cases in which no breakage occurred are marked as ○.

From Table 1, it can be seen that the lower opening pieces 9 with a maximum height of 3 mm and 5 mm from the bottom surface 3 were broken, but those with a maximum height of 8 mm or more were not broken. If the maximum height of the lower opening piece 9 from the bottom surface 3 is less than 5 mm, the bottom corner of the round-bottomed bottle container will be strongly pressed against the lower opening piece 9 in a dotted manner when it is dropped, resulting in the pressing force It is thought that it was unable to withstand the force and broke. On the other hand, if the maximum height of the lower opening piece 9 from the bottom surface 3 is 8 mm or more, when the bottle container with a round bottom is dropped, the bottom corners of the round-bottomed bottle are pressed against the lower opening piece 9 in a dotted manner, but the lower side wall It is considered that the cut line portion 8 did not break because the strength of the cut line portion 8 was higher than that of the cut line portion less than 5 mm. Furthermore, from this test result, setting the maximum height of the lower opening piece 9 from the bottom surface 3 to 8 mm or more is suitable for containers that are morphologically similar to round-bottomed bottle containers, that is, the lower opening piece 9 The same effect can be obtained for containers in which pressure occurs at point-like contact portions between the containers, for example, containers whose bottom contours are polygonal or more than pentagons. It is thought that the effect of not breaking can be obtained.

From the above, the strength of the lower opening piece 9 in the paper box 1 (the strength of the lower side wall cut line part 8) is increased by setting the maximum height of the lower opening piece 9 from the bottom surface part 3 to 8 mm or more. It can be seen that it is possible to more effectively prevent the package from being accidentally opened due to impact during transportation. The lower opening piece 9 is the starting point for opening the bottom part 3 by breaking the bottom cut line, and is preferably configured to a size that can be pushed in with a human finger. Since the side wall portion 2 on which the lower opening piece 9 is provided is also the part where the product name and various product descriptions are displayed, it is preferable to configure the lower opening piece 9 so that it does not become too large. Therefore, it is preferable that the maximum height of the lower opening piece 9 from the bottom surface 3 is in the range of 8 mm or more and 20 mm or less, and more preferably 8 mm or more and 15 mm or less.

Furthermore, in this embodiment, as shown in FIG. 1, since the lower opening piece 9 is formed into an isosceles trapezoid shape, the lower side wall cut line part 8 is the boundary between the bottom part 3 and the back plate 32. It is configured to include an upper side portion 81 that is substantially parallel to a portion 22a of the corner portion ridgeline 22 that constitutes the corner portion ridge line 22. It is said that the strength of the lower opening piece 9 is increased by configuring the length of the coverlet part (upper side coverlet part) forming a part of the upper side part 81 to be in the range of 2.5 mm or more and 3.5 mm or less. This is preferable from the viewpoint of improving ease of opening. In this regard, the inventor of the present invention conducted a test and confirmed its effectiveness, and the content and results of the test will be explained below.

First, regarding the test content, similar to the test content regarding the strength confirmation regarding the maximum height of the lower opening piece 9 from the bottom surface 3 described above, a prescribed medicine storage container is housed in the paper box 1 according to the present invention. Prepare a set of 8 pharmaceutical packaging bodies that have been packaged using tape and bundle them with tape. This was done by allowing the sample to fall freely onto a surface and checking whether the lower opening piece 9 would break due to the impact. The aspect of the pharmaceutical packaging set is also similar, and as shown in the schematic diagram of FIG. The pharmaceutical packaging bodies 61 are arranged in a 2×2 arrangement. Furthermore, when dropping the pharmaceutical packaging set 60, as shown in FIG. I let it happen. The individual paper boxes 1 included in the pharmaceutical package set 60 are arranged so that the lower opening pieces 9 are all placed on the side shown by arrow A in FIG. 6(b). Further, each paper box 1 is formed by assembling individual box forming sheets 30 as shown in FIG.

The pharmaceutical packaging set to be subjected to the drop test is a paper box in which the bottom part 3 and the top part 4 have a square shape of 4.8 cm x 4.8 cm, and the height of the side wall part 2 is 8.1 cm. 1. D type: 6 sets consisting of tablets (100 tablets) stored in a bottle container with a bottle standard of 8K, the bottom part 3 and the top part 4 having a square shape of 6.1 cm x 6.1 cm. E type: 6 sets, consisting of a paper box 1 with a side wall 2 having a height of 12.1 cm, and tablets (280 tablets) stored in a bottle container with a bottle standard of 13K. Consisting of a paper box 1 with a top surface 4 having a square shape of 6.8 cm x 6.8 cm and a side wall 2 having a height of 15 cm, tablets (420 tablets) are stored in a dedicated bottle container. A total of 18 sets, 6 sets of F type, were prepared. The weight of each drug package included in the D-type to F-type drug package set is 78 g for D type, 288 g for E type, and 489 g for F type. Note that the bottle container in which each tablet is stored has a circular bottom contour.

In the pharmaceutical packaging set as described above, the length of the coverlet part (upper side coverlet part) that constitutes a part of the upper side part 81 of the lower opening piece 9 of the paper box 1 is configured to be different for each set. ing. The lengths of the upper side coveralls in each set are 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, and 4.0 mm, and are formed at two locations on the upper side 81. In other words, for any set of D type, E type, and F type, two joint parts (upper side joint part) are formed in a part of the upper side part 81, and the length of each joint part is 1.5 mm, 2. Pharmaceutical packaging sets of .0 mm, 2.5 mm, 3.0 mm, 3.5 mm, and 4.0 mm were prepared and a drop test was conducted. Note that, as shown in FIGS. 1 and 3, each lower opening piece 9 is attached to a portion 22a of the corner ridgeline 22 that forms the boundary between the bottom surface 3 and the back plate 32 (the boundary between the bottom surface 3 and the side wall 2). It is formed into an isosceles trapezoid shape with the lower base being a part of the . Here, the length of the portion corresponding to the lower base of the isosceles trapezoidal lower opening piece 9 is 25 mm, and the length of the upper base (upper side portion 81) is 18 mm. Further, the height of the lower opening piece 9 from the bottom part 3 (height from the bottom part 3 to the upper side part 81) is 8 mm. In addition, a 1.5 mm hooked portion is formed at the center of a portion of the lower side wall cut line portion 8 disposed between the bottom surface portion 3 and the upper side portion 81.

Each pharmaceutical package set 60 configured as described above was dropped onto the floor from a height of 100 cm, and it was confirmed whether or not the lower opening piece 9 had broken. Table 2 shows the results. In Table 2, in the strength evaluation column, cases in which the lower opening piece 9 was broken are marked as x, and cases in which no breakage occurred are marked as ○. In addition, we also checked the ease of opening, and in the ease of opening column in Table 2, we marked ◎ for packages that were judged to be extremely easy to open, and marked ○ for packages that we judged to be able to open without any problems. , Those that are difficult to open are marked as ×. Table 2 also shows the ratio (g/cm ² ) of the weight of the container containing the medicine to the area of the bottom surface 3 of the paper box 1.

From Table 2, if the length of the coverlet part (upper side coverlet part) that constitutes a part of the upper side part 81 of the lower opening piece 9 is 2.5 mm or more, it is applicable to any of the D type, E type, and F type. It can be seen that no rupture occurred. Furthermore, focusing on the relationship between the ratio (g/cm ² ) of the weight of the container containing pharmaceuticals to the area of the bottom surface 3 of the paper box 1 and the presence or absence of breakage, the bottom surface 3 of the paper box 1 When storing a heavy item in the paper box 1, the ratio (g/cm ² ) of the weight of the container containing the medicine to the area of 4 g/cm ² or more is formed as a part of the upper side 81. It is thought that the lower opening piece 9 can be effectively prevented from breaking by setting the length of the upper sleeve portion to 2.5 mm or more. Also, from Table 2, the length of the coverlet part (upper side coverlet part) that constitutes a part of the upper side part 81 is 4.0 mm, although no breakage occurs, but the strength of the coverlet part (upper side coverlet part) is Because of the high price, it was found that it was difficult to open the package by hand. Therefore, in order to exhibit good unsealability while having strength to withstand shock during transportation, the length of the coverlet part (upper side coverlet part) that constitutes a part of the upper side part 81 is set to 2. It can be said that it is preferable to set it in the range of .5 mm or more and 3.5 mm or less.
