Description

[Technical Field]

[0001] The present invention relates to a packaging material, a processing tool, and a packaging device. [Background technology]

[0002] Patent Document 1 below discloses a technology relating to a package (packaging material) having perforations for cutting. According to this prior art, the package can be separated along the perforations. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-306419 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above prior art, it is difficult to tear the package along the perforation with one hand, and there is room for improvement in this regard.

[0005] In consideration of the above, an object of the present invention is to provide a packaging material that can be easily torn along a perforation with one hand, as well as a processing tool and a packaging device for manufacturing the packaging material. [Means for solving the problem]

[0006] A first aspect of the packaging material is a packaging material having perforations formed thereon, the perforations being configured to include a plurality of slits arranged in series, the packaging material being formed with notches at its ends so as to connect to end slits of the plurality of slits, the notches being formed so that the width of the notches increases the farther away from the perforations, and the edges of the notches have curved portions formed in a concave curve. Note that the concept of "arranged in series" includes cases where the slits are arranged in a straight line as well as cases where the slits are arranged in a curved line.

[0007] According to a first aspect of the packaging material, the perforations formed in the packaging material include a plurality of slits arranged in series, and the packaging material has a notch formed at an end thereof so as to connect to an end slit among the plurality of slits. Here, the notch width is formed to increase with increasing distance from the perforation, and the edge of the notch has a curved portion formed in a concave curve. Therefore, a person attempting to separate the packaging material along the perforation with one hand, for example, a right-handed person, can hold the packaging material with the notch on the left side and with at least a portion of the curved portion facing downward, grasp the packaging material near the upper side of the notch with their index finger and thumb, hook their middle finger or ring finger into the curved portion of the edge of the notch, and bend the hooked finger toward the base of their thumb, thereby being able to separate the packaging material along the perforation with one hand.

[0008] To further explain, in the packaging material of the first aspect, the portion of the edge of the notch where the finger is hooked can be a concave curved portion rather than a straight portion, thereby increasing the length of the portion where the finger can be hooked relative to the edge of the notch. As a result, even if a user makes a large stroke of bending a finger hooked on the edge of the notch toward the base of the thumb, the finger generally does not come out of the notch, and the force generated by the series of movements of the finger can be used to separate the packaging material. Furthermore, because the notch is connected to the slit on the edge, the separation along the perforation can be initiated with a small force. Furthermore, as the packaging material is gradually separated along the perforation, the distance between the portion of the packaging where the hooked finger applies force and the portion to be separated increases, increasing the distance from the fulcrum to the force point, thereby allowing the packaging material to be separated with a correspondingly small force. As described above, the packaging material of the first aspect allows the packaging material to be separated along the perforation with one hand.

[0009] In the packaging material of the second aspect, in the first aspect, the cutout portion is formed in an approximately V-shape, and one edge extending from the point connecting to the slit on the end side is a straight portion formed in a straight line, and the other edge extending from the point connecting to the slit on the end side is the curved portion.

[0010] According to the packaging material of the second aspect, the notch is formed in a substantially V-shape, and one edge extending from the point connecting with the end slit is a linear portion formed in a straight line, and the other edge extending from the point connecting with the end slit is the curved portion. By making only the other edge a curved portion in this way, the portion to hook the fingers is visually easy to understand.

[0011] The packaging material of the third aspect is the same as that of the first or second aspect, in which the slit holes constituting the holes among the plurality of slits are set to the same length, and the length of the slits on the end side is set to be shorter than the length of the slit holes.

[0012] According to the packaging material of the third aspect, the slit holes that constitute the holes among the multiple slits are set to the same length, and the length of the slit on the end side is set to be less than the length of the slit hole, so it is less likely that the material will start to separate inadvertently from the slit on the end side.

[0013] The packaging material of the fourth aspect, in any one of the first to third aspects, has a plurality of packaging bags formed in succession so as to be lined up in series in a first direction, the perforations are formed at the boundaries between adjacent packaging bags, the plurality of slits extend along a second direction perpendicular to the first direction, and the cutout portions are formed at the boundaries between adjacent packaging bags and on the side edge side.

[0014] According to a fourth aspect of the packaging material, a plurality of packaging bags are formed in series in a first direction, perforations are formed at the boundaries between adjacent packaging bags, and a plurality of slits extend along a second direction perpendicular to the first direction. Furthermore, the cutouts are formed at the boundaries between adjacent packaging bags and on the side edge side. This allows a user to separate adjacent packaging bags by cutting the packaging material from the cutouts along the perforations with one hand.

[0015] The packaging material of the fifth aspect is the fourth aspect, in which an opening cut portion is formed in the area where the multiple slits are arranged in series, with the longitudinal direction being a direction intersecting the direction in which the multiple slits are arranged.

[0016] According to the packaging material of the fifth aspect, in the area where the multiple slits are arranged in series, a cut portion for opening is formed, cut in a direction that intersects with the direction in which the multiple slits are arranged as the longitudinal direction.Therefore, after the packaging bag is cut from the notch along the perforation, the packaging bag can be opened from the cut portion.

[0017] A sixth aspect of the packaging material is the fifth aspect, wherein the cut portion is a slit that is cut in a straight line so as to intersect with at least one of the plurality of slits.

[0018] According to the packaging material of the sixth aspect, the cut portion is a notch portion cut in a straight line so as to intersect with at least one of the multiple slits, so that despite the simple configuration, the packaging bag can be easily opened from the notch portion after being cut along the perforation from the notch portion.

[0019] The packaging material of the seventh aspect is the packaging material of the fifth aspect, wherein the cut portion has a diamond-shaped cut portion formed through the material in a diamond shape, and the longitudinal center position of the diamond-shaped cut portion is aligned with the multiple slits.

[0020] According to the seventh aspect of the packaging material, the cut portion has a diamond-shaped cut portion formed through it, and the longitudinal center position of the diamond-shaped cut portion is aligned with the multiple slits, so when the packaging bag is cut from the cut portion along the perforation, a V-shaped cut portion that is half of the diamond-shaped cut portion is formed in the packaging bag. Therefore, when the packaging bag is cut from the cut portion along the perforation, it is easy to visually tell which part to open the packaging bag from.

[0021] The packaging material of an eighth aspect is the seventh aspect, wherein the cut portion includes extended cut portions cut continuously along the first direction from corners on both sides in the longitudinal direction of the diamond-shaped cut portion.

[0022] According to the packaging material of the eighth aspect, the cut portion has an extended cut portion cut along the first direction continuously to the corners on both sides of the longitudinal direction of the diamond-shaped cut portion, so that when the packaging bag is cut from the cutout portion along the perforation, the packaging bag can be easily opened from the extended cut portion continuous to the corners of the V-shaped cut portion, which is half of the diamond-shaped cut portion.

[0023] The processing tool of the ninth embodiment has a plurality of first blade portions arranged in a series and forming a perforation including a plurality of slits arranged in a series in the packaging material, and a second blade portion formed continuously with the end-side first blade portion of the plurality of first blade portions and forming a cutout portion at the end of the packaging material that connects to the end-side slit of the plurality of slits, and the second blade portion is configured so that the cutout portion formed at the end of the packaging material has a width that increases the further away from the perforation, and so that a concave curved portion is formed on at least a portion of the edge of the cutout portion.

[0024] According to a ninth aspect of the processing tool, a plurality of first blade portions arranged in series form perforations in the packaging material, including a plurality of slits arranged in series. Furthermore, a second blade portion formed continuously with an end-side first blade portion of the plurality of first blade portions forms a notch at the end of the packaging material, connecting to the end-side slit of the plurality of slits. Here, the second blade portion is configured so that the notch formed at the end of the packaging material has a width that increases with increasing distance from the perforation, and so that at least a portion of the edge of the notch forms a concavely curved portion. As described above, the perforations and notches in the packaging material of the first aspect can be formed using the first blade portion and the second blade portion, and therefore the packaging material with the perforations and notches formed using the first blade portion and the second blade portion can be torn along the perforations with one hand.

[0025] The processing tool of the tenth aspect has a blade portion that forms a notch at the end of a packaging material on which a perforation including a plurality of slits arranged in series is formed, and that forms a notch that connects to one of the end-side slits of the plurality of slits, and the blade portion is configured so that the notch formed at the end of the packaging material has a width that increases the further it is from the perforation, and so that a concave curved portion is formed on at least a portion of the edge of the notch.

[0026] According to the processing tool of the tenth aspect, the blade portion forms a notch at the end of a packaging material having a perforation including a plurality of slits arranged in series, the notch connecting to one of the slits at the end. Here, the blade portion is configured so that the notch formed at the end of the packaging material has a width that increases the farther it is from the perforation, and so that a concave curve is formed on at least a portion of the edge of the notch. As described above, the blade portion can be used to form the notch in the packaging material of the first aspect, and the packaging material with the notch formed using the blade portion can be cut along the perforation with one hand.

[0027] The packaging device of the 11th aspect is a packaging device that packages an object to be packaged, and has a seal forming section that forms a seal by welding so that multiple packaging areas arranged in series are formed in the packaging material, and the processing tool described in claim 9, and is configured to press the multiple first blade portions and the second blade portions against the packaging material between adjacent packaging areas to form the perforations between the adjacent packaging areas and to form the cutout portion at the end of the packaging material.

[0028] According to the packaging device of the eleventh aspect, the seal forming unit forms seals by welding so as to form a plurality of packaging regions arranged in series in the packaging material. The packaging device of the eleventh aspect also presses the plurality of first blade portions and second blade portions of the processing tool of the ninth aspect against the packaging material between adjacent packaging regions, forming perforations between the adjacent packaging regions and notches at the end of the packaging material. This makes it possible to produce packaging material that allows adjacent packaging regions to be separated along the perforations with one hand.

[0029] The packaging device of the 12th aspect is a packaging device that packages an object to be packaged, and includes a seal forming unit that forms a seal by welding so that a plurality of packaging areas arranged in series are formed in the packaging material, a perforation forming unit that forms perforations including a plurality of slits arranged in series in the packaging material between adjacent packaging areas, and the processing tool described in claim 10, and is configured to press the blade unit against the end of the packaging material on which perforations including a plurality of slits arranged in series have been formed by the perforation forming unit between adjacent packaging areas, to form the notch that connects to one of the slits on the end side of the plurality of slits.

[0030] According to a packaging device of the twelfth aspect, a seal forming unit forms a seal by welding so as to form a plurality of packaging regions arranged in series in the packaging material. The perforation forming unit forms perforations including a plurality of slits arranged in series in the packaging material between adjacent packaging regions. The packaging device of the twelfth aspect also presses the blade of the processing tool of the tenth aspect against an end of the packaging material on which perforations including a plurality of slits arranged in series between adjacent packaging regions have been formed by the perforation forming unit, forming a notch that connects to one of the slits on the end side. This makes it possible to manufacture a packaging material that allows adjacent packaging regions to be separated along the perforations with one hand. [Effects of the Invention]

[0031] As described above, the packaging material of the present invention allows the packaging material to be easily torn along the perforations with one hand. Furthermore, the processing tool and packaging device of the present invention make it possible to manufacture packaging material that can be easily torn along the perforations with one hand.

DETAILED DESCRIPTION OF THE INVENTION

[0033] [First embodiment] A packaging material, a processing tool, and a packaging device according to a first embodiment of the present invention will be described with reference to the drawings.

[0034] First, a packaging material according to a first embodiment will be described. Fig. 1 shows a plan view of a drug package 10 as a packaging material according to the first embodiment of the present invention. As shown in Fig. 1, the drug package 10 has a plurality of packets 12 as packaging bags formed continuously and arranged in series in a first direction LD. Each packet 12 contains a predetermined amount of drug (not shown, e.g., powder or granules).

[0035] The outer peripheral edge of each packet 12 (top, bottom, left and right edges in the drawing) is a sealed portion 14 formed by welding. The sealed portion 14 has a certain width. In the drug package 10, perforations 20 are formed at the boundaries between adjacent packets 12. The perforations 20 are formed in the sealed portion 14.

[0036] The perforations 20 are configured to include a plurality of slits 22 arranged in series. The plurality of slits 22 extend along a second direction WD that is perpendicular to the first direction LD. The plurality of slits 22 are formed at equal intervals (for example, at intervals of 2 mm). Slit holes 22H that form holes among the plurality of slits 22 (in FIG. 1, the slits 22 other than those formed at both ends) are set to the same length (for example, 3 mm).

[0037] In addition, in the region where the plurality of slits 22 are arranged in series, a notch 24 is formed as a cut portion for opening, cut in a longitudinal direction intersecting the direction in which the plurality of slits 22 are arranged. The notch 24 is formed in the seal portion 14, and is cut in a straight line so as to intersect (here, as an example, perpendicular to) one of the plurality of slits 22. As an example, the notch 24 is formed in a portion of the drug package 10 near the end opposite the cutout 30 side.

[0038] As a modification of this embodiment, multiple cuts (24) may be formed. That is, multiple cuts (24) may be formed in the drug package (10) in a linear fashion so as to intersect with two or more of the multiple slits (22).

[0039] The drug package 10 has a notch 30 formed by cutting out an end portion so as to connect to an end-side slit 22A of the multiple slits 22. The length of the end-side slit 22A connected to the notch 30 is set to be equal to or shorter than the length of the slit hole 22H. The notch 30 is formed at the boundary between adjacent packets 12 and on the side edge 10S side of the drug package 10. The portion where the notch 30 is formed is the seal portion 14.

[0040] The cutout 30 is formed in a substantially V-shape so that the cutout width (the vertical distance between the upper and lower edges 30A, 30B in the drawing) increases the farther away from the perforation 20. The cutout 30 has one edge 30A extending from a point 30X connected to the end slit 22A as a straight portion 32 formed in a straight line, and the other edge 30B extending from the point 30X connected to the end slit 22A as a curved portion 34 formed in a concave curve.

[0041] Although not shown in the figures, characters are printed on the medicine package 10 assuming that the first direction LD is the up-down direction, and Fig. 1 shows the characters in a state where they are normally readable (the characters are not upside down). Here, the curved portion 34 is set below the notch 30 in the state shown in Fig. 1.

[0042] The curved portion 34 is designed to hook the middle or ring finger, and the notch 30 is shaped to fit the shape of the middle or ring finger so that a portion of the middle or ring finger can be hooked onto the curved portion 34. The distance between the two ends of the curved portion 34 is preferably 4 mm to 6 mm, which is approximately half the width of the middle or ring finger at a midpoint from the base of the nail to the tip. In this embodiment, the distance is set to 5 mm, for example. The average width of the middle finger at a midpoint from the base of the nail to the tip is 11.5 mm for Japanese adult males, 9.8 mm for Japanese adult females, and 10.9 mm for Japanese adult females. The average width of the ring finger at a midpoint from the base of the nail to the tip is 10.7 mm for Japanese adult males, 8.9 mm for Japanese adult females, and 10.1 mm for Japanese adult females.

[0043] Next, a processing tool and a packaging device for manufacturing the drug package 10 according to this embodiment will be described. Fig. 2 shows a simplified schematic diagram of a part of a drug package manufacturing device 40 as a packaging device equipped with a punching tool 50 as a processing tool according to this embodiment, as seen from the front. The drug package manufacturing device 40 is a packaging device that packages drugs as packaging objects.

[0044] 2, medicine package manufacturing apparatus 40 has a roll support shaft 41 that supports a long strip-shaped packing sheet S in a rolled state so that it can be unwound, a sheet support shaft 42 that supports the packing sheet S to be conveyed, and a drive roller 43 for conveying the packing sheet S. Drive roller 43 is provided on the downstream side of the conveyance route of the packing sheet S, and is controlled by a control device (not shown) to intermittently move the packing sheet S in response to a predetermined operation by a user. The packing sheet S is folded in half along a center line parallel to the longitudinal direction of the packing sheet S.

[0045] Furthermore, medicine package manufacturing apparatus 40 has medicine insertion section 44 for inserting medicines, and hopper 45 provided directly below medicine insertion section 44. Although not shown in detail, the lower part of hopper 45 is inserted into the opening (between the ends on the opposite side to the folding line side) of the conveyed packaging sheet S.

[0046] A stamp device 46 is provided downstream of the lower part of hopper 45 in the conveying direction of the packaging sheet S. Stamp device 46 includes a seal forming section 48 (shown as a block in the figure) that forms seal section 14 (see FIG. 1) by welding on the packaging sheet S containing medicines, and a punching tool 50 (shown as a block in the figure) that forms perforations 20 and cutout sections 30 (both see FIG. 1) in the packaging sheet S. Stamp device 46 is controlled by a control device (not shown) and operates in response to a predetermined operation by a user. Seal forming section 48 forms seal section 14 (see FIG. 1) so as to form a plurality of packaging regions arranged in series on the packaging sheet S, which is the packaging material.

[0047] Fig. 3 shows a cross-sectional view of a main part of the punching tool 50 cut along a direction perpendicular to the punching direction. As shown in Fig. 3, the punching tool 50 has a plurality of first cutting edges 52 arranged in series, and a second cutting edge 54 formed continuously with a first cutting edge 52A on the end side of the plurality of first cutting edges 52.

[0048] The first blade portion 52 punches out perforations 20 including a plurality of slits 22 arranged in series as shown in FIG. 1 (see FIG. 1 for both). The first blade portion 52 shown in FIG. 3 includes a horizontal blade portion 52X that forms the plurality of slits 22 arranged in series (see FIG. 1), and a vertical blade portion 52Y that intersects (here, as an example, is perpendicular to) one of the plurality of first blade portions 52. The vertical blade portion 52Y forms a cut portion 24 that intersects one of the plurality of slits 22 shown in FIG. 1.

[0049] The second blade portion 54 shown in FIG. 3 is punched to form a notch 30 at the end of the packaging sheet S (see FIG. 2) that connects to the end-side slit 22A of the multiple slits 22 shown in FIG. 1. The second blade portion 54 shown in FIG. 3 is formed in a generally V-shape that is open on the side opposite the multiple first blade portions 52, and includes a straight blade portion 54A that extends linearly from the portion connecting to the end-side first blade portion 52A, and a curved blade portion 54B that extends in a curved manner from the portion connecting to the end-side first blade portion 52A. The curved blade portion 54B is curved so that one side of the generally V-shape of the second blade portion 54 bulges slightly outward. In other words, the second blade portion 54 is configured to form the notch 30 at the end of the packaging sheet S (see FIG. 2) whose notch width increases with increasing distance from the perforation 20 shown in FIG. 1, and to form a concavely curved portion 34 at part of the edge of the notch 30.

[0050] That is, the stamp device 46 shown in Figure 2 is configured to press a plurality of first blade portions 52 and second blade portions 54 shown in Figure 3 against the packaging sheet S between adjacent packaging areas, thereby forming perforations 20 (see Figure 1) between the adjacent packaging areas and forming cutout portions 30 at the end of the packaging sheet S.

[0051] Next, the operation of the drug package manufacturing apparatus 40 shown in FIG. 2 will be outlined. After the packing sheet S is set so that it can be moved by the operation of the drive roller 43, when the drive roller 43 is operated in response to a predetermined user operation, the long strip-shaped packing sheet S supported in a roll state on the roll support shaft 41 is sequentially unwound and moved downstream in the conveyance direction. Drugs input into the drug input section 44 are supplied to the double-folded packing sheet S via a hopper 45. The packing sheet S to which the drugs have been supplied has a seal portion 14 formed by a seal portion forming section 48 of the stamp device 46, and a perforation 20 and a cutout portion 30 formed by a punching tool 50 of the stamp device 46. The packing sheet S that has passed through the stamp device 46 is discharged into a predetermined storage box as a drug package 10 (see FIG. 1). As described above, the drug package 10 shown in FIG. 1 can be obtained.

[0052] (Actions and Effects) Next, the operation and effect of the medicine package 10 as the packaging material of the first embodiment will be described.

[0053] 1, according to this embodiment, the perforation 20 formed in the drug package 10 includes a plurality of slits 22 arranged in series, and the drug package 10 has a notch 30 formed by cutting out an end portion thereof so as to connect with an end slit 22A of the plurality of slits 22. Here, the notch 30 is formed so that the width of the notch increases with increasing distance from the perforation 20, and the edge of the notch 30 has a curved portion 34 formed in a concave curve. This allows the user to separate the drug package 10 from the notch 30 along the perforation 20 with one hand.

[0054] Furthermore, in this embodiment, multiple packets 12 are formed continuously so as to be lined up in series in the first direction LD, perforations 20 are formed at the boundaries between adjacent packets 12, and multiple slits 22 extend along a second direction WD that is perpendicular to the first direction LD. Also, cutouts 30 are formed at the boundaries between adjacent packets 12 and on the side edge 10S side. This allows a user to separate adjacent packets 12 by cutting the medicine package 10 from cutouts 30 along perforations 20 with one hand.

[0055] More specifically, a person who wishes to separate the drug packaging 10 along the perforation 20 with one hand, for example a right-handed person, holds the drug packaging 10 with the notch 30 positioned on the left side and the curved portion 34 facing downwards, as shown in Figure 4A, grasps the drug packaging 10 near the upper side of the notch 30 with the index finger F2 and thumb F1, and then hooks the middle finger F3 (or ring finger F4) around the curved portion 34 at the edge of the notch 30, passes through the state shown in Figure 4B, and bends the middle finger F3 (or ring finger F4) hooked on the curved portion 34 (see Figure 4A) toward the base of the thumb F1, as shown in Figure 4C, thereby allowing the drug packaging 10 to be separated along the perforation 20 (see Figure 4A) with one hand H1.

[0056] As a supplemental explanation, in the drug package 10 of this embodiment shown in FIG. 1, the portion of the edge of the cutout 30 where the finger is hooked can be a concavely curved portion 34 rather than a straight portion, thereby increasing the length of the portion where the finger can be hooked relative to the cutout 30. As a result, even if a finger (middle finger F3 in the figure) is hooked on the edge 30B of the cutout 30 shown in FIG. 4A and then the finger (middle finger F3 in the figure) is bent toward the base of the thumb F1 as shown in FIG. 4C with a large stroke, the finger (middle finger F3 in the figure) basically does not come out of the cutout 30 (see FIG. 4A), and therefore the force generated by the series of movements of the finger (middle finger F3 in the figure) can be used to separate the drug package 10. Furthermore, because the cutout 30 is connected to the slit 22A on the end side as shown in FIG. 4A, separation along the perforation 20 can be initiated with a small force. Furthermore, as the drug packaging 10 is sequentially separated along the perforations 20, the distance between the part of the drug packaging 10 where force is applied from the hooked finger (finger F3 in the figure) shown in Figure 4C etc. and the part to be separated becomes longer, and the distance from the fulcrum to the point of force becomes longer, so that the drug packaging 10 can be separated with a correspondingly smaller force. As described above, with the drug packaging 10 of this embodiment shown in Figure 1, the drug packaging 10 can be separated along the perforations 20 with one hand.

[0057] Here, a sensory evaluation test conducted to evaluate the ease of separation and the results thereof will be described.

[0058] First, drug packages (samples) of an example of the present invention and several comparative examples prepared for a sensory evaluation test will be described with reference to Figures 7A to 7E. The drug packages (samples) shown in Figures 7A to 7E are made of the same material as drug package 10 shown in Figure 1. Reference numeral 114 in Figures 7A to 7E denotes a seal portion substantially similar to seal portion 14 shown in Figure 1, and reference numeral 112 in Figures 7A to 7E denotes a packet substantially similar to packet 12 shown in Figure 1.

[0059] The drug packaging 101 configured as shown in Figure 7A is Comparative Example 1, and has perforations 120 formed at the boundary between adjacent packets 112, each consisting of a plurality of linear slits 122 arranged in series. The slits 122 (122A) at both ends of the perforation 120 are cut from both ends of the drug packaging 101. The drug packaging 102 configured as shown in Figure 7B is Comparative Example 2, and has perforations 220 formed by pores 222 and cuts 223 instead of the slits 122 (see Figure 7A) of Comparative Example 1, and the perforations 220 are formed by pores 222 and cuts 223, each having a shape similar to two arcs facing each other.

[0060] The drug package 103 shown in Fig. 7C is Comparative Example 3, and in addition to the configuration of the drug package 101 of Comparative Example 1 (see Fig. 7A), short cuts 322 are formed perpendicular to the longitudinal centers of the multiple slits 122 except for the slits 122 (122A) on both ends. That is, the drug package 103 shown in Fig. 7C has slits 122 and cuts 322 in perforations 320. The drug package 104 shown in Fig. 7D is Comparative Example 4, and has, as perforations 420, multiple linear slits 422 lined up in series at the boundary between adjacent packets 112, and V-shaped intermittent slits 423 that are open on the side opposite to the multiple slits 422 at the boundary between adjacent packets 112 on the side of side edge 104S of the drug package 104.

[0061] The medicine packaging 106 shown in Figure 7E is an embodiment of the present invention, and has substantially the same configuration as that shown in Figure 1, except that the notch 24 (see Figure 1) is not formed in the perforation 620. For convenience, in Figure 7E, the components related to the slit 22 and the notch 30 are denoted by the same reference numerals as in Figure 1.

[0062] In this sensory evaluation test, 16 research subjects used one hand to separate the perforated portions of Comparative Examples 1 to 4 and the Example, and then performed a subjective evaluation of the ease of separation. The sensory evaluation of the ease of separation was performed using the VAS (Visual Analogue Scale) method.

[0063] Figure 5 shows the results of the sensory evaluation test in a bar graph. Figure 5 shows the cumulative results of the sensory evaluation using the VAS method, with smaller values ​​on the vertical axis indicating easier separation. On the horizontal axis, the words "pierce" in parentheses represent cases where the drug package was primarily gripped near the perforation with the thumb, index finger, and middle finger, and then pierced the perforation with the thumb to separate it. The words without parentheses represent cases where the drug package was gripped above the perforation with the thumb and index finger, and then the middle or ring finger was used to separate the perforation. Incidentally, in Comparative Example 1, for which there is no parenthetical notation, the medicine package 101 (see FIG. 7A) is grasped above the perforation with the thumb and index finger, and then the medicine package 101 (see FIG. 7A) is pressed against the pad of the thumb, for example, from the middle finger side, and moved in short strokes to slightly separate the perforation 120 shown in FIG. 7A, and then the position where the thumb and index finger grasp the medicine package 101 is shifted and the perforation 120 is again slightly separated. As shown in FIG. 5, the cumulative value of the sensory evaluation in this sensory evaluation test showed that the Example was the easiest to separate.

[0064] The results of the sensory evaluation test are shown in a pie chart in Figure 6. Figure 6 is a graph of the total number of cases in which each research subject felt that the eight patterns shown on the horizontal axis of Figure 5 were the easiest to separate. As shown in Figure 6, the majority of cases in which the example was felt to be the easiest to separate were those in the example.

[0065] As can be seen from the results of the sensory evaluation test, the configuration of the example is superior in terms of ease of separation.

[0066] As described above, according to the drug packaging 10 of this embodiment shown in Fig. 1, the drug packaging 10 can be easily torn with one hand along the perforation 20. Therefore, even a person who has difficulty using one hand due to illness, an aftereffect of an accident, or the like can tear the drug packaging 10 along the perforation 20.

[0067] Furthermore, even if a cutout portion 30 is formed in the drug packaging body 10, the impact on the strength of the drug packaging body 10 against pulling in the first direction LD is very small, so there is no risk of it breaking at the perforation 20 during manufacturing.

[0068] In this embodiment, the notch 30 is formed in a substantially V-shape, with one edge 30A extending from a point 30X connected to the end slit 22A as a straight line portion 32, and the other edge 30B extending from the point 30X connected to the end slit 22A as a curved portion 34. By having only the other edge 30B as a curved portion 34, the portion where the finger is to be hooked is visually easy to understand.

[0069] In this embodiment, if the drug packaging body 10 is held in a position where the characters (not shown) printed on the drug packaging body 10 can be read normally (the characters are not upside down), the curved portion 34 will be located on the lower side of the cutout portion 30, so the drug packaging body 10 can be separated with one hand without changing the up-down orientation of the drug packaging body 10.

[0070] Furthermore, in this embodiment, the slit holes 22H constituting the holes among the multiple slits 22 are set to the same length, and the length of the end-side slit 22A is set to be equal to or less than the length of the slit hole 22H, so that it is unlikely that separation will start inadvertently from the end-side slit 22A side.

[0071] In addition, in this embodiment, in the area where multiple slits 22 are arranged in series, an opening notch 24 is formed, cut in a direction that intersects with the direction in which the multiple slits 22 are arranged, so that after the packet 12 is cut from the notch 30 along the perforation 20, the packet 12 can be opened from the notch 24.

[0072] Furthermore, the cutout 24 is cut in a straight line so as to intersect with one of the plurality of slits 22, so that the packet 12 can be easily opened from the cutout 24 after being cut off from the cutout 30 along the perforation 20, despite the simple structure.

[0073] [Second embodiment] Next, a second embodiment of the present invention will be described with reference to FIG. 8. FIG. 8 shows a plan view of a drug package 60 as a packaging material according to the second embodiment of the present invention. As shown in FIG. 8, the drug package 60 according to this embodiment differs from the drug package 10 according to the first embodiment (see FIG. 1) in that it includes a diamond-shaped cut portion 64 as a cut portion shown in FIG. 8, instead of the cross-shaped cut portion formed by the cut portion 24 shown in FIG. 1 and one slit hole 22H intersecting the cut portion 24. The other configuration of the drug package 60 according to the second embodiment is substantially similar to that of the drug package 10 according to the first embodiment (see FIG. 1). Therefore, components in the second embodiment that are substantially similar to those in the first embodiment are designated by the same reference numerals, and description thereof will be omitted.

[0074] The diamond-shaped cut portion 64 is formed in an area where the multiple slits 22 are lined up in series, and is a cut portion for opening that is cut with the longitudinal direction intersecting the direction in which the multiple slits 22 are lined up. The diamond-shaped cut portion 64 is formed through in a diamond shape, and the center position of the diamond-shaped cut portion 64 in the longitudinal direction is aligned with the multiple slits 22. In other words, the positions in the first direction LD of the corners 64A on both sides of the diamond-shaped cut portion 64 in the short direction are aligned with the positions of the multiple slits 22 in the first direction LD. The diamond-shaped cut portion 64 and the multiple slits 22 form the perforation 62.

[0075] The drug package 60 according to the second embodiment provides substantially the same functions and effects as the drug package 10 according to the first embodiment (see FIG. 1 ). Regarding differences from the first embodiment, in this embodiment, after the packet 12 is separated from the cutout 30 along the perforation 62, the packet 12 can be opened from the diamond-shaped cut portion 64. When the packet 12 is separated from the cutout 30 along the perforation 62, a V-shaped cut portion, which is half of the diamond-shaped cut portion 64, is formed in the packet 12. Therefore, when the packet 12 is separated from the cutout 30 along the perforation 62, it is easy to visually determine which portion of the packet 12 to open.

[0076] [Third embodiment] Next, a third embodiment of the present invention will be described with reference to Fig. 9. Fig. 9 shows a plan view of a drug package 70 as a packaging material according to the third embodiment of the present invention. As shown in Fig. 9, the drug package 70 according to this embodiment has a configuration in which an extended cutout portion 76 is added to the configuration of the drug package 60 according to the second embodiment (see Fig. 9). Therefore, components in the third embodiment that are substantially similar to those in the second embodiment are given the same reference numerals and will not be described.

[0077] In the region of the drug package 70 where the plurality of slits 22 are arranged in series, a cut section 74 for opening is formed by cutting the longitudinal direction in a direction intersecting the direction in which the plurality of slits 22 are arranged. The cut section 74 includes a diamond-shaped cut section 64 and an extended cut section 76 cut along the first direction LD, continuing from corners 64B on both sides of the diamond-shaped cut section 64 in the longitudinal direction. The cut section 74, together with the plurality of slits 22, constitutes a perforation 72.

[0078] The configuration of the third embodiment also provides the same effects and advantages as those of the second embodiment. Furthermore, in the drug package 70 according to the third embodiment, the cut portion 74 includes an extended cut portion 76 that is cut along the first direction LD and continues to the corners 64B on both longitudinal sides of the diamond-shaped cut portion 64. Therefore, when the packet 12 is separated from the notch 30 along the perforation 72, the packet 12 can be easily opened from the extended cut portion 76 that is continuous to the corners 64B of the V-shaped cut portion that is half of the diamond-shaped cut portion 64.

[0079] [Fourth embodiment] Next, a fourth embodiment of the present invention will be described with reference to FIG. 10. FIG. 10 shows a plan view of a drug package 80 as a packaging material according to the fourth embodiment of the present invention. As shown in FIG. 10, the drug package 80 according to this embodiment differs from the drug package 10 according to the first embodiment (see FIG. 1) in that it has a cutout 82 shown in FIG. 10 instead of the cutout 30 shown in FIG. 1. Other configurations of the drug package 80 according to the fourth embodiment are substantially similar to those of the drug package 10 according to the first embodiment (see FIG. 1). Therefore, components in the fourth embodiment that are substantially similar to those in the first embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted.

[0080] 10, the notch 82 is formed in a substantially V-shape so that the notch width increases with increasing distance from the perforation 20, and one edge 82A extending from a point 82X connecting with the end slit 22A is formed as a concavely curved curved portion 84, while the other edge 82B extending from the point 82X connecting with the end slit 22A is formed as a concavely curved curved portion 86. That is, the drug packaging body 80 according to this embodiment has a configuration in which a curved portion 84 is formed instead of the straight portion 32 (see FIG. 1) of the notch 30 in the first embodiment.

[0081] According to the fourth embodiment described above, the drug packaging body 80 can also be easily torn off with one hand along the perforation 20. Furthermore, in this embodiment, even if the drug packaging body 80 is upside down, the drug packaging body 80 can be easily torn off with one hand along the perforation 20.

[0082] [Fifth embodiment] Next, a fifth embodiment of the present invention will be described with reference to FIG. 11. FIG. 11 shows a plan view of a drug package 90 as a packaging material according to the fifth embodiment of the present invention. As shown in FIG. 11, the drug package 90 according to this embodiment differs from the drug package 10 according to the first embodiment (see FIG. 1) in that it has a cutout 92 shown in FIG. 11 instead of the cutout 30 shown in FIG. 1. Other configurations of the drug package 90 according to the fifth embodiment are substantially similar to those of the drug package 10 according to the first embodiment (see FIG. 1). Therefore, components in the fifth embodiment that are substantially similar to those in the first embodiment are designated by the same reference numerals, and descriptions thereof will be omitted.

[0083] 11, the notch 92 is formed in a substantially V-shape so that the notch width increases with increasing distance from the perforation 20, and one edge 92A extending from a point 92X connecting with the end slit 22A is formed as a convexly curved convex portion 94, while the other edge 92B extending from the point 92X connecting with the end slit 22A is formed as a concavely curved concave portion 96. That is, the drug package 90 according to this embodiment has a configuration in which the convexly curved portion 94 is formed instead of the straight portion 32 (see FIG. 1) of the notch 30 in the first embodiment.

[0084] According to the fifth embodiment described above, the medicine packaging body 90 can also be easily torn along the perforation 20 with one hand.

[0085] [Sixth embodiment] Next, a sixth embodiment of the present invention will be described with reference to Fig. 12 and Fig. 13. Fig. 12 shows a perspective view of a punch 150 as a processing tool according to the sixth embodiment, and Fig. 13 shows a plan view of the punch 150.

[0086] 12 has a base 152, a handle portion 156 provided on the base 152 via a support portion 154, and a blade portion 158 (see FIG. 13) provided between the base 152 and an upper plate portion 156A of the handle portion 156. The basic structure of the punch 150 is the same as that of a known punch.

[0087] The base 152 is configured to be able to hold the edge of a packaging material such as the medicine package 101 shown in FIG. 7A, and as an example, a linear alignment mark 152M shown in FIG. 12 is provided on the edge of the top surface. The linear mark 152M is provided to align the perforations on the edge of the packaging material. The handle portion 156 is pivotally supported on the side closer to the linear mark 152M so as to be rotatable about an axis along the width direction 150W of the punch 150, and is configured to be able to be pressed down in the direction of arrow D. The blade portion 158 shown in FIG. 13 is configured to descend in response to the downward pressing of the handle portion 156.

[0088] Blade portion 158 is used to form a notch connecting to one of the slits at the end of a packaging material (e.g., medicine package 101 shown in FIG. 7A) on which perforations including multiple slits arranged in series are formed. Blade portion 158 is formed in a generally V-shape with the side opposite to linear mark 152M open in plan view, and includes linear blade portion 158A that forms one side of the generally V-shape and extends linearly, and curved blade portion 158B that forms the other side of the generally V-shape and extends in a curved manner. Curved blade portion 158B is curved so that one side of the generally V-shape of blade portion 158 bulges outward slightly. Furthermore, intersection 158X between linear blade portion 158A and curved blade portion 158B is located on an extension of linear mark 152M in plan view.

[0089] As a result, the blade portion 158 is configured to form a notch (see notch 30 shown in Figure 1) at the end of the packaging material (for example, the left end of the drug packaging body 101 shown in Figure 7A) whose width increases the further it is from the perforation of the packaging material (for example, see perforation 120 shown in Figure 7A), and to form a concave curved portion (see curved portion 34 shown in Figure 1) on part of the edge of the notch.

[0090] When using punch 150, for example, by pinching the end of drug package 101 (see FIG. 7A) between base 152 and handle portion 156, aligning perforation 120 (see FIG. 7A) with linear mark 152M, and then pressing down handle portion 156, notch 30 can be formed as shown in FIG. 1. That is, using punch 150 shown in FIGS. 12 and 13, drug package 10 as shown in FIG. 1 can be manufactured.

[0091] The punch 150 may have a handle portion 156 that is manually depressed, or may be incorporated into a part of a drug packaging manufacturing apparatus and have the handle portion 156 that is electrically depressed, as in the seventh embodiment described below.

[0092] [Seventh embodiment] A seventh embodiment of the present invention will be described with reference to Fig. 14. Fig. 14 shows a simplified schematic front view of a portion of a medicine package manufacturing apparatus 140 as a packaging apparatus according to the seventh embodiment. The medicine package manufacturing apparatus 140 is a packaging apparatus that packages medicines as packaging objects.

[0093] As shown in Figure 14, the drug package manufacturing apparatus 140 differs from the drug package manufacturing apparatus 40 shown in Figure 2 in that it includes a stamp device 146 shown in Figure 14 instead of the stamp device 46 of the drug package manufacturing apparatus 40 of the first embodiment shown in Figure 2, but in other respects it has substantially the same configuration as the drug package manufacturing apparatus 40 shown in Figure 2. Therefore, in the drug package manufacturing apparatus 140 shown in Figure 14, components that are substantially similar to those of the drug package manufacturing apparatus 40 shown in Figure 2 will be assigned the same reference numerals and descriptions thereof will be omitted.

[0094] Stamp device 146 is provided downstream of the lower part of hopper 45 in the conveying direction of packaging sheet S. Stamp device 46 is controlled by a control device (not shown) and operates in response to a predetermined operation by a user, and has a seal forming unit 48, a perforation forming unit 149, and a punch 150. In the drawing, seal forming unit 48, perforation forming unit 149, and punch 150 are each shown as a block.

[0095] The seal forming section 48 is a component similar to the seal forming section 48 of the stamp device 46 of the first embodiment (see Figure 2 for both), and is configured to form a seal section 14 (see Figure 1) by welding so that multiple packaging areas arranged in series are formed on the packaging material, i.e., the packaging sheet S.

[0096] The perforation forming unit 149 is configured to form perforations 20 (see FIG. 1) including a plurality of slits 22 arranged in series between adjacent packaging areas in the packaging sheet S. Although not shown in detail, the perforation forming unit 149 is equipped with a perforation forming blade similar to the first blade 52 of the punching tool 50 of the first embodiment, and presses the perforation forming blade against the packaging sheet S between adjacent packaging areas to form perforations 20 (see FIG. 1) between the adjacent packaging areas.

[0097] Punch 150 has the same configuration as punch 150 of the sixth embodiment shown in Figures 12 and 13, and a handle portion 156 is electrically depressed. Stamp device 146 shown in Figure 14 is configured to press blade portion 158 (see Figure 13) against an end of packaging sheet S on which perforations 20 (see Figure 1) including a plurality of slits 22 arranged in series by perforation forming portion 149 are formed between adjacent packaging regions, to form notch 30 (see Figure 1) connected to one of slits 22A on the end side of the plurality of slits 22.

[0098] In the stamp device 146 described above, the packaging sheet S supplied with medicines has seals 14 formed by the seal forming unit 48, perforations 20 formed by the perforation forming unit 149, and notches 30 formed by the punch 150. As a result, the medicine package 10 shown in FIG. 1 can also be manufactured by the medicine package manufacturing apparatus 140 according to the seventh embodiment.

[0099] [Supplementary explanation of the embodiment] The second blade portion 54 of the punching tool 50 as a processing tool shown in Figure 3 and the blade portion 158 of the punch 150 as a processing tool shown in Figure 13 are configured so that a concavely curved portion is formed on part of the edge of the cutout in the packaging material, but as a variant, the second blade portion or the blade portion may be configured so that a concavely curved portion is formed on the entire edge of the cutout in the packaging material.

[0100] Furthermore, in the above embodiment shown in Figures 1 to 14, the cutouts 30, 82, 92 are formed in an approximately V-shape, but as a modification of the above embodiment, the cutouts may be formed in, for example, a semicircular arc shape or an approximately U-shape.

[0101] In addition, in the above embodiment, the packaging material is described as being a drug package 10, 60, 70, 80, or 90, but as a variation of the above embodiment, the packaging material may be a packaging material other than a drug package, such as individual packaging material for food, etc.

[0102] Furthermore, in the above embodiment, the notches 30, 82, 92 and the multiple slits 22 are provided for separating the packets 12 from each other, but the notches and the multiple slits may also be provided for opening. As a variation of the above embodiment, the cut portions (notch portion 24, diamond-shaped cut portion 64, cut portion 74) may not be provided, and a notch and multiple slits may be provided separately for opening.

[0103] In addition, in the above embodiment, the length of the end-side slit 22A is set to be equal to or shorter than the length of the slit hole 22H, and such a configuration is preferable, but as a variation of the above embodiment, a configuration in which the length of the end-side slit (22A) is very slightly longer than the length of the slit hole (22H) can also be adopted.

[0104] The above-described embodiment and the above-described modifications can be implemented in appropriate combinations.

[0105] The above describes one example of the present invention, but the present invention is not limited to the above, and it goes without saying that the present invention can be implemented in various modified forms within the scope of the gist of the present invention. [Explanation of symbols]
