Description

[Technical Field]

[0001] The present invention relates to a blister package that can be used to package, for example, medicines, food, cosmetics, etc. [Background technology]

[0002] Press-through pack (PTP) packaging sheets are widely used for packaging tablets, capsules, etc., because they allow tablets to be easily removed, are highly moisture-proof, are convenient for portability, transportability, and management, and are relatively inexpensive to manufacture. A PTP is a type of so-called blister package (blister pack), and is formed by laminating a sheet of aluminum foil or the like to a main body sheet made of synthetic resin, which has multiple storage recesses for storing tablets, etc., to close the openings of the storage recesses.

[0003] Blister packages are widely used not only for pharmaceuticals but also for packaging foods such as confectionery, cosmetics, miscellaneous goods, batteries, daily necessities, etc. Conventional blister packages have tear lines formed as slit-like grooves or perforations between each storage recess in the main body sheet, and some are known to be able to be separated into predetermined packaging units (see, for example, Patent Document 1). Figs. 20 and 21 show an example of a conventional blister package 100 in which storage recesses 102 for storing tablets or the like are formed in two columns and five rows in a main body sheet 101. In the conventional example of Fig. 20, vertical tear lines 104 and horizontal tear lines 105 are formed between each storage recess 102 so that the storage recesses can be separated one by one. These vertical and horizontal tear lines allow the required number of tablets (e.g., one, two, three, etc.) to be separated, and the tablets can be taken out or carried. On the other hand, in a configuration in which the storage recesses can be separated one by one, such as the conventional example in Fig. 20, there is a risk of accidentally swallowing the separated blister pack sheet by putting it in one's mouth and drinking it, and there have been cases of accidental ingestion in the past. In contrast, in recent years, as shown in Fig. 21, a configuration in which only a horizontal cutting line 105 is formed so that two storage recesses 102 lined up side by side can be separated as the smallest unit has become popular.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 8-058839 Summary of the Invention [Problem to be solved by the invention]

[0005] In conventional blister packages such as those shown in Figures 20 and 21, for example, when a pharmacist dispenses tablets or the like, they often cut the sheet from the blister package at desired positions as needed to divide it into the required number of storage recess units, and then hand over the prescribed amount to the patient. Furthermore, when a patient goes out, they often cut the sheet into the required number of storage recess units themselves so that they can take only the required number of tablets or the like with them. With the structure of conventional blister packages, for example, when cutting off storage recesses lined up in a row at the same time, that is, when cutting off an even number of storage recesses, such as 2, 4, etc., in a sheet configuration of 2 columns and 5 rows, the sheets can be easily cut off along the linear horizontal cutting lines. However, for example, when a blister package has a sheet configuration of 2 columns and 5 rows and needs to be separated into odd numbers of tablets, such as 1 tablet, 3 tablets, or 5 tablets, it is necessary to separate the tablets partway along the horizontal perforation lines and then along the vertical perforation lines, which requires extremely careful work to avoid cutting along the extra perforation lines, resulting in cumbersome, time-consuming, and inconvenient tasks. In particular, a blister package such as that shown in Figure 21 has only horizontal perforation lines, so that cutting into an odd number of tablets requires a tool such as scissors, and the cutting work with scissors is also cumbersome and time-consuming. Furthermore, accurate separation is difficult, and there is a risk of accidentally cutting along the extra perforation lines or tearing the storage recess or its closure, which can lead to the loss of tablets or the incorrect number of tablets.

[0006] The present invention has been made in view of the above-mentioned problems of the conventional art, and one object of the present invention is to provide a highly practical blister package having multiple storage sections that can be quickly and accurately separated into any number of storage sections with a single, extremely simple manual action. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a blister package comprising a main body sheet in which a plurality of recessed storage sections for storing packaged items are arranged vertically and horizontally, and a lid sheet attached to the main body sheet so as to close the openings of the storage sections of the main body sheet, wherein the main body sheet is formed with vertical division line portions that enable the storage sections to be separated into predetermined units, and horizontal division line portions that intersect with the vertical division line portions, and the vertical division line portions are formed with first cutting line portions that are formed at a predetermined length from either end side so that the main body sheet can be cut, and horizontal division line portions that intersect with the first cutting line portions. Department and a narrow slit portion including a narrow opening extending from the other end along the same line as the main body sheet, and the horizontal dividing line portion is formed so that the main body sheet can be cut and has a second cutting line portion whose end faces the narrow slit portion.

[0008] The first cutting line portion of the vertical dividing line portion may be set at a position corresponding to the storage portion arranged on either end side in the vertical direction.

[0009] The slits and the first cutting line portions may be provided alternately in the lateral direction.

[0010] The first cutting line portion or the second cutting line portion is the cutting line Department The thickness may be gradually reduced toward the end portion.

[0011] The second cutting line may be provided in a direction inclined with respect to the longitudinal direction of the narrow slit.

[0012] The vertical dividing line may have an easily breakable portion at an end or middle position of the narrow slit that locally connects the main body sheet portions on both sides of the narrow slit so that the main body sheet portions can be cut.

[0013] The first cutting line portion or the second cutting line portion may have one or more gaps. [Effects of the Invention]

[0014] According to the blister package of the present invention, there is provided a blister package comprising a main body sheet in which a plurality of recessed storage sections for storing packaged items are arranged vertically and horizontally, and a lid sheet attached to the main body sheet so as to close the openings of the storage sections of the main body sheet, wherein the main body sheet is formed with vertical division line portions that enable the storage sections to be separated into predetermined units, and horizontal division line portions that intersect with the vertical division line portions, and the vertical division line portions are formed with first cutting line portions that are formed at a predetermined length from either end side so that the main body sheet can be cut, and horizontal division line portions that intersect with the first cutting line portions. Department and a narrow slit portion including a narrow opening extending from the other end along the same line as the first cutting line, and the horizontal dividing line portion is formed so that the main body sheet can be cut and has a second cutting line portion whose end faces the narrow slit portion. Therefore, when separating into any number of storage units, any number of storage units can be separated by cutting only one cutting line portion, either the first cutting line portion or the second cutting line portion, using the narrow portion.As a result, the desired number of storage units can be separated quickly and reliably with just one extremely simple manual action, and a blister package with high separation operability and practicality can be provided.

[0015] By configuring the first cutting line portion of the vertical dividing line portion to be set at a position corresponding to the storage section located on either end side in the vertical direction, even in a structure with a narrow slit portion, the sheet portions on both sides of the narrow slit portion can be connected relatively stably without impairing the ease of separation, and the strength of the entire main sheet can be maintained.

[0016] By configuring the slits and the first cutting lines to be alternately provided in the horizontal direction, the storage sections can be reliably separated in any number of units, which can further improve practicality.

[0017] The first cutting line portion or the second cutting line portion is the cutting line Department By configuring the end portion so that the thickness gradually decreases, the cutting operation along the cutting line can be performed more smoothly, and burrs are less likely to occur after cutting, allowing for a relatively clean cut.

[0018] By configuring the second cutting line portion to be arranged in a direction inclined relative to the longitudinal direction of the narrow slit portion, it is easier to perform the cutting operation on the second cutting line portion and it is also easier for the user to visually grasp the cutting direction, further improving operability.

[0019] By configuring the vertical dividing line to have an easy-to-tear portion at the end or middle of the narrow slit that locally connects the main sheet portions on both sides of the narrow slit so that the portions can be torn, the sheet portions on both sides of the narrow slit can be connected relatively stably and the strength of the main sheet can be maintained without substantially impairing operability even in a structure with a narrow slit. As a result, for example, it is possible to effectively prevent the narrow slits from getting pinched together, making it difficult to handle when handling, transporting, storing, etc., multiple blister packages, or to prevent the blister packages from accidentally separating at a part other than the intended cutting part when separating the desired number of packages.

[0020] By configuring the first cutting line portion or the second cutting line portion to have one or more gaps, the cutting operation of the cutting line portion can be performed more smoothly and the cutting can be performed relatively cleanly. [Brief explanation of the drawings]

[0022] An embodiment of a blister package according to the present invention will now be described with reference to the accompanying drawings. The blister package according to the present invention is a sheet-like packaging container used for packaging, for example, medicines, cosmetics, food, miscellaneous goods, daily necessities, etc. in tablet, capsule, or any other solid, powder, granular, liquid, jelly, or other form.

[0023] Figures 1 to 5 show a first embodiment of a blister package of the present invention. As shown in Figures 1, 2, and 3, a blister package 10 according to this embodiment comprises a main body sheet 14 in which a plurality of storage sections 12 are formed, and a lid sheet 16 attached to the main body sheet 14. Furthermore, the main body sheet 14 is formed with vertical dividing lines 18 that allow the plurality of storage sections 12 to be separated into predetermined units, and horizontal dividing lines 20 that intersect with the vertical dividing lines.

[0024] In this embodiment, the blister package 10 will be described as an example of a PTP (Press Through Pack) packaging sheet in which the packaged item is, for example, a circular tablet of a predetermined thickness, the lid sheet 16 is formed of aluminum foil, and by pressing the storage section 12 with a finger from the outside, that part of the lid sheet 16 breaks, allowing the tablet to be taken out.

[0025] The main body sheet 14 is a packaging sheet body formed with a plurality of recessed storage compartments 12 arranged lengthwise and widthwise to accommodate packaged items. In this embodiment, the main body sheet 14 is made of a thin sheet material formed of a single layer or multiple layers of synthetic resin such as polyvinyl chloride, polypropylene, or polyethylene, with an outline shape of a substantially rounded rectangle. As shown in Figures 1, 2, and 3, the main body sheet 14 is made of synthetic resin, and the storage compartments 12 are integrally formed by recessing the synthetic resin sheet in a substantially cylindrical or truncated cone shape at predetermined positions to accommodate tablets, which are packaged items. In this embodiment, for example, one main body sheet 14 has a total of 10 storage compartments 12, arranged in a vertical arrangement of 2 compartments and a horizontal arrangement of 5 compartments. In this embodiment, the longitudinal direction of the main body sheet 14 is the horizontal direction W, and the direction perpendicular to the horizontal direction is the vertical direction H.

[0026] The lid sheet 16 is a closing sheet material or mount attached to the main body sheet 14 so as to close the opening of the storage section 12 of the main body sheet 14. In this embodiment, the lid sheet 16 is formed of, for example, aluminum foil, has the same outer contour shape as the main body sheet 14, and is adhered to the main body sheet 14 to seal the storage section 12.

[0027] The vertical dividing lines 18 and the horizontal dividing lines 20 are sheet dividing means for dividing the main body sheet 14 into units of a predetermined number of storage compartments 12. In this embodiment, as shown in Figures 1, 2, and 3, the vertical dividing lines 18 are formed linearly along the vertical direction H, and four vertical dividing lines 18 are formed at predetermined intervals corresponding to the midpoints between storage compartments 12 lined up in the horizontal direction W. Each vertical dividing line 18 has a first cutting line 22 and a narrow slit 24 formed on the same line as the first cutting line 22.

[0028] The first cutting line 22 is formed to be easily cut by forming the main body sheet 14 thinner than other portions. The first cutting line 22 is formed, for example, at a predetermined length from the end of two storage compartments 12 arranged vertically, corresponding to the position of one of the storage compartments 12 at the end. Furthermore, the first cutting line 22 is formed alternately in the horizontal direction W to correspond to the upper storage compartment 12 and the lower storage compartment 12. The first cutting line 22 is not limited to the above-described form and may be formed, for example, by a notch formed along the longitudinal direction or a perforation. Furthermore, the first cutting line 22 may be formed with a substantially triangular or tapered pointed shape at both ends in a longitudinal cross section along its longitudinal direction, as in the second cutting line 28 described below. That is, the first cutting line 22 may be formed so that its thickness gradually decreases toward both ends of the first cutting line 22, as shown in FIG. 4 .

[0029] As shown in FIG. 1 , the narrow slits 24 include narrow, slit-shaped openings extending in the vertical direction. The narrow slits 24 are provided with a length corresponding to the storage sections 12 on the other end side of the first cutting line 22. The narrow slits 24 are provided long from the other end side of the first cutting line 22 toward the end side of the first cutting line 22. Thus, the narrow slits 24 are formed in the horizontal direction W to alternately correspond to the lower storage sections 12 and the upper storage sections 12, so as to be in the opposite position to the first cutting line 22. In other words, the narrow slits 24 and the first cutting line 22 are provided alternately in the horizontal direction W.

[0030] An easily breakable section 26 is provided on the outer end side of the narrow slit 24 of the main body sheet 14. The easily breakable section 26 is formed to locally connect the sheet portions on both sides of the narrow slit 24 in the lateral direction and to be cut more easily than other portions. The easily breakable section 26 is formed, for example, so as to gradually narrow the gap width of the narrow slit 24 and finally connect both sides of the gap.

[0031] Furthermore, at the vertical dividing line portion 18, the main body sheet 14 is cut out in a rounded shape at both ends of the first cutting line portion 22. The main body sheet 14 is also cut out in a rounded shape at the end of the narrow slit portion 24 on the first cutting line portion 22 side. In addition, the main body sheet 14 on the outer side of the easily breakable portion 26 is cut out in a rounded shape. This makes it easy to grasp the position of the vertical dividing line portion 18 and to perform the separation operation. At the same time, because the rounded chamfer remains even after separation, the user is less likely to get injured, and the product can be used and carried safely.

[0032] The horizontal dividing line 20 has a second cutting line 28 extending horizontally to cut the main body sheet 14. The second cutting line 28 intersects with the vertical dividing line 18, with its ends facing the ends of the narrow slits 24. In this embodiment, the second cutting line 28 has a predetermined length corresponding to the positions of the five storage compartments 12 aligned in the horizontal direction W, with the five storage compartments 12 arranged side by side in the horizontal direction with the narrow slits 24 sandwiched between them. The second cutting line 28 is formed to be thinner than the other portions of the main body sheet 14, allowing for easy cutting. Furthermore, as shown in FIG. 4 , the second cutting line 28 is gradually thinner toward both end portions 28a of the second cutting line 28. That is, when viewed in a longitudinal cross section along the longitudinal direction of the second cutting line 28, both end portions 28a are formed to have a generally triangular or tapered pointed shape. This allows for a smooth and easy cutting operation from the end side (28a) of the second cutting line 28, and the cutting is relatively neat. The second cutting line 28 is not limited to the above-described form, and may be formed, for example, by a notch formed along the longitudinal direction or by a perforation. The second cutting line 28 (first cutting line 22) may have a shape such as that shown in FIG. 6. For example, as shown in FIG. 6(a), the second cutting line 28 may have the same thickness along the longitudinal direction. As shown in FIG. 6(b), the second cutting line 28 may have one or more gaps 30 at a midpoint in the longitudinal direction. As shown in FIG. 6(c), the second cutting line 28 may have one or more gaps 30 at a midpoint and gradually become thinner toward both end portions 28a, forming a triangular or tapered shape. Like the second cutting line portion 28, the first cutting line portion 22 may also be formed in the shape shown in FIG.

[0033] In this embodiment, the second cutting lines 28 are formed so as to be inclined at an obtuse angle θ with respect to the longitudinal direction of the narrow slit 24. Therefore, adjacent second cutting lines 28 corresponding to laterally adjacent storage sections 12 are arranged symmetrically with respect to the narrow slit 24, with alternating upward and downward slopes like mountains and valleys. Furthermore, the main body sheet 14 is cut out in a rounded shape at both ends of the second cutting lines 28. This makes it easy to grasp the position of the horizontal dividing line 20 and to perform the separation operation. At the same time, since the rounded chamfer remains even after separation, the user is less likely to get injured, and the product can be used and carried safely.

[0034] A case will be described where the blister package 10 according to this embodiment is cut into units of a predetermined number of containing sections 12. For example, when cutting out one (or nine) containing sections 12, the cutting direction of the blister package 10 shown in FIG. <0> - <1> By using one slit portion 24 and one second cutting line portion 28, which are on a line, and tearing them apart, it is possible to easily separate only one storage portion 12 as a unit, as shown in the lower diagram of FIG. 5. It is also possible to easily separate them by a cutting operation such as bending and stretching the second cutting line portion 28. Similarly, when separating two (or eight) storage portions 12 as a unit, it is possible to easily separate them by a cutting operation such as bending and stretching the second cutting line portion 28. <0> - <2> The separation can be easily achieved by using one slit 24 and one first cutting line 22 formed in a straight line. When separating three (or seven) storage sections 12 as a unit, the separation can be easily achieved by using the slit 24 and first cutting line 22 formed in a straight line. <0> - <3> - <5> The two narrow slits 24 on the line and one second cutting line 28 with both ends facing the narrow slits 24 can be easily separated. When separating four (or six) storage units, the <4> - <5> The container can be easily separated by tearing it apart using one slit 24 and one first cutting line 22 formed in a straight line. When separating five containers 12 as a unit, the container can be easily separated by tearing it apart using the slit 24 and first cutting line 22 formed in a straight line. <5> - <6> - <7> The two slits 24 on the line and one second cutting line 28 having both ends facing the slits 24 can be used to easily separate the pieces.

[0035] In this way, regardless of the number of storage sections 12 to be separated, it is only necessary to use one or two narrow slits 24 and separate only one of the first cutting lines 22 or the second cutting lines 28. Because the vertical dividing lines 18 are divided by the narrow slits 24, the cutting operation along the first cutting lines 22 or the second cutting lines 28 can be performed simply and accurately. As a result, a predetermined number of storage sections 12 can be separated simply, quickly, and accurately with a single manual action. As described above, the blister package 10 of this embodiment can provide a highly practical blister package with significantly improved cutting operability compared to the conventional blister package 100 shown in FIG. 20 described above, which has a structure in which cutting lines simply intersect vertically and horizontally.

[0036] Next, second to fourteenth embodiments of the blister package of the present invention will be described with reference to Figures 7 to 19. In each embodiment, the same components as those in the above-described embodiments are designated by the same reference numerals, and detailed description thereof will be omitted. Each of the second to fourteenth embodiments is basically the same as the first embodiment, comprising a main body sheet 14 having a plurality of storage compartments 12 arranged thereon and a lid sheet 16, with the main body sheet 14 having vertical dividing lines 18 and horizontal dividing lines 20 formed therein. Furthermore, the vertical dividing lines 18 also have first cutting lines 22 and narrow slits 24, and the horizontal dividing lines 20 also have second cutting lines 28 whose ends face the narrow slits 24. Therefore, each embodiment can achieve the same advantageous effects as the above-described embodiment, such as the ability to easily and quickly separate the package into a predetermined number of storage compartments with a single operation.

[0037] As shown in Fig. 7, a blister package 10-2 according to the second embodiment has substantially the same configuration as the first embodiment, but the shape of the second cutting line 28 is slightly different. In this embodiment, the second cutting line 28 is formed to a length corresponding to each storage section 12, and a small oval or dot-shaped gap 30 is provided at the midpoint so as to divide the second cutting line 28 in the longitudinal direction. Therefore, the vertical cross-sectional shape of the second cutting line 28 is as shown in Fig. 6(c). This embodiment also has the same advantageous effects as the above-mentioned embodiment, such as the ability to easily and quickly separate the package into a predetermined number of storage sections with a single operation.

[0038] 8, a blister package 10-3 according to the third embodiment has substantially the same configuration as that of the first embodiment, but is slightly different in the shape of the second cutting line 28. In this embodiment, the second cutting line 28 is set perpendicular to the longitudinal direction of the slit 24.

[0039] 9, a blister package 10-4 according to the fourth embodiment has substantially the same configuration as the first embodiment, but is slightly different in the shape of the vertical dividing line portion 18. In this embodiment, the easy-to-break portion 26 is formed at the middle position in the longitudinal direction of the narrow slit portion 24, and is formed as two separate portions: a first narrow opening 32 that communicates with the outer end side of the narrow opening, and a second narrow opening 33 that is connected to the first cutting line portion 22 and the second cutting line portion 28.

[0040] 10, a blister package 10-5 according to the fifth embodiment has substantially the same configuration as that of the fourth embodiment, but is slightly different in the shape of the second cutting line 28. In this embodiment, the second cutting line 28 is set perpendicular to the longitudinal direction of the slit 24.

[0041] 11, a blister package 10-6 according to the sixth embodiment has substantially the same configuration as the first embodiment, but is slightly different in the shape of the vertical dividing line portion 18. In this embodiment, there is no easily breakable portion 26 as in the first embodiment, and the narrow slit portion 24 is formed as a narrow opening that continues from the end of the first cutting line portion 22 to the outer end side.

[0042] 12, a blister package 10-7 according to the seventh embodiment has substantially the same configuration as that of the sixth embodiment, but is slightly different in the shape of the second cutting line 28. In this embodiment, the second cutting line 28 is set perpendicular to the longitudinal direction of the slit 24.

[0043] As shown in Fig. 13, a blister package 10-8 according to the eighth embodiment has a configuration similar to that of the first embodiment, but differs in the shape of the main body sheet 14. In this embodiment, the storage section 12 of the main body sheet 14 is formed in an oval shape that is longer in one direction when viewed from the front. Furthermore, the main body sheet 14 is formed in a generally rounded rectangular shape that is longer in the vertical direction than in the above-described embodiments, corresponding to the oval shape of the storage section 12. This embodiment can be used, for example, when the packaged items are spindle-shaped tablets, capsules, etc.

[0044] 14, a blister package 10-9 according to the ninth embodiment has substantially the same configuration as the eighth embodiment, but is slightly different in the shape of the second cutting line 28. In this embodiment, the second cutting line 28 is set perpendicular to the longitudinal direction of the slit 24.

[0048] 18, a blister package 10-13 according to the thirteenth embodiment has substantially the same configuration as the twelfth embodiment, but is slightly different in the shape of the second cutting line 28. In this embodiment, the second cutting line 28 is set perpendicular to the longitudinal direction of the slit 24.

[0049] As shown in Fig. 19, a blister package 10-14 according to the fourteenth embodiment has a configuration similar to that of the first embodiment, but differs in the shapes of the main body sheet 14, vertical dividing line portions 18, and horizontal dividing line portions 20. In this embodiment, the main body sheet 14 has a total of 15 storage sections 12, with five storage sections 12 formed horizontally and three storage sections 12 formed vertically. Furthermore, the main body sheet 14 is formed in a generally rounded rectangular shape that is longer in the vertical direction than the first embodiment.

[0050] The vertical dividing line 18 has a first cutting line 22 formed at a position corresponding to one of the three storage sections 12 arranged vertically, either at the upper end or the lower end. Therefore, the narrow slit 24 is formed longer than the first cutting line 22 to correspond to the remaining two of the three storage sections 12 arranged vertically. The narrow slit 24 is formed so as to extend from the end of the first cutting line 22 to the other end (upper or lower end) of the main body sheet 14. The horizontal dividing line 20 includes second cutting lines 28 formed between each of the three storage sections 12 arranged vertically. The second cutting lines 28 are set perpendicular to the longitudinal direction of the narrow slit 24.

[0051] In this embodiment, too, the easy-to-break portion 26 may be provided on the outer end side or in the middle of the narrow slit portion 24. The second cutting line portion 28 may be formed at an angle with respect to the longitudinal direction of the narrow slit portion 24. The storage portions 12 may be arranged in an M number of rows and M columns of N number of storage portions 12 (M and N are positive integers). The vertical dividing line portions 18 and the horizontal dividing line portions 20 are set in accordance with the arrangement of the storage portions 12.

[0052] The blister package of the present invention described above is not limited to the configuration of the above-described embodiment, and any modifications may be made without departing from the essence of the present invention as defined in the claims. [Industrial Applicability]
