Description

Blister packaging

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

[0002] Press-through pack (PTP) packaging sheets are widely used for packaging tablets, capsules, etc., because they allow easy removal of tablets, 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 packaging medicines but also for packaging foods such as confectionery, cosmetics, miscellaneous goods, batteries, daily necessities, etc. Conventional blister packages have tear lines formed by slit-like grooves or perforations between each storage recess in a main body sheet, allowing them to be separated into predetermined packaging units (see, for example, Patent Document 1). Figures 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 shown in Figure 20, vertical tear lines 104 and horizontal tear lines 105 are formed between each storage recess 102 so that the storage recesses 102 can be separated one by one. These vertical and horizontal tear lines allow the user to separate the required number of tablets (e.g., one, two, three, etc.) and take them out to take or carry. On the other hand, in the conventional example shown in Fig. 20 where the storage recesses can be separated one by one, there is a risk of accidentally swallowing the separated blister pack sheet by putting it in the 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 type 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] Japanese Patent Application Publication No. 8-058839

[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 at desired positions from the blister package as needed to divide it into the required number of storage recesses, 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 recesses themselves so that they can carry only the required number of tablets or the like. 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 two, four, etc., in a sheet configuration of two columns and five rows, cutting can be easily done 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, 3, or 5, it is necessary to perform two separate operations, one to separate along the horizontal perforation lines and the other 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, with a blister package such as that shown in Fig. 21 , which has only horizontal perforation lines, tools such as scissors are required to separate the packages into odd numbers of tablets, 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.

[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 in the main body sheet, wherein the main body sheet is formed with vertical dividing line portions that allow the plurality of storage sections to be separated into predetermined units, and horizontal dividing line portions that intersect the vertical dividing line portions, and the vertical dividing line portions have a first cutting line portion formed to a predetermined length from either end side so that the main body sheet can be cut, and a narrow slit portion that extends from the other end side along the same line as the first cutting line portion and includes a narrow opening, and the horizontal dividing line portion is formed so that the main body sheet can be cut, and has a second cutting line portion that is formed so that the main body sheet can be cut, and has an end facing 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 may be formed so that the thickness gradually decreases toward the end of the cutting line 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.

[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 sections that enable the storage sections to be separated into predetermined units, and horizontal division line sections that intersect with the vertical division line sections, and the vertical division line sections are formed with a first cutting line section that is formed at a predetermined length from either end side so that the main body sheet can be cut, and a horizontal division line section that is formed at the other end side along the same line as the first cutting line section. and a narrow slit portion including a long, narrow opening extending from the main sheet, and the horizontal dividing line portion is formed so that the main sheet can be cut and has a second cutting line portion with its end facing the narrow slit portion. Therefore, when separating any number of storage units, any number of units can be separated by using the narrow portion to cut only one of the first cutting line portion or the second cutting line portion. As a result, with just one extremely simple manual action, the desired number of units can be separated quickly and reliably, providing a blister package that is easy to separate and highly practical.

[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, the sheet portions on both sides of the narrow slit portion can be connected relatively stably without impairing the ease of separation even in a structure provided with a narrow slit portion, and the strength of the entire main sheet can be maintained.

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

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

[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.

[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 applied to 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 when the storage section 12 is pressed with a finger from the outside, the relevant 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 multiple 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 or multiple layers of synthetic resin, such as polyvinyl chloride, polypropylene, or polyethylene, with an outline shape of a substantially rectangular shape with rounded corners. As shown in Figures 1, 2, and 3, the main body sheet 14 has storage compartments 12 integrally formed by recessing the synthetic resin sheet into a substantially cylindrical or truncated cone shape at predetermined positions to accommodate the packaged tablets. In this embodiment, for example, one main body sheet 14 has a total of 10 storage compartments 12 arranged in a vertical and horizontal arrangement of two by five. 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 backing 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. Note that the lid sheet 16 is not limited to aluminum foil, and may be made of any material, such as paper, synthetic resin such as plastic, or any other material that can be torn when a predetermined force is applied.

[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. For example, the first cutting line 22 is formed a predetermined length from the end of one 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 with 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 18, the main body sheet 14 is cut out in a rounded shape at both ends of the first cutting line 22. The main body sheet 14 is also cut out in a rounded shape at the end of the narrow slit 24 on the first cutting line 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 18 and to perform the cutting operation. At the same time, because the rounded chamfer remains even after cutting, the user is less likely to get injured, and the product can be used and carried safely.

[0032] The horizontal dividing line 20 has second cutting lines 28 extending horizontally to cut the main body sheet 14. The second cutting lines 28 intersect the vertical dividing line 18, with their ends facing the ends of the narrow slits 24. In this embodiment, the second cutting lines 28 are formed with predetermined lengths 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 lines 28 are formed to be thinner than the remaining portions of the main body sheet 14, allowing for easy cutting. Furthermore, as shown in FIG. 4 , the second cutting lines 28 are gradually thinner toward both end portions 28a of the second cutting lines 28. That is, in a longitudinal cross section of the second cutting lines 28 along the longitudinal direction, 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 also 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. For example, as shown in FIG. 6(b), the second cutting line 28 may have one or more gaps 30 at the intermediate position in the longitudinal direction. For example, as shown in FIG. 6(c), the second cutting line 28 may have one or more gaps 30 at the intermediate position 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 inclined at an obtuse angle θ relative 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 uphill and downhill slopes like mountains and valleys. Furthermore, the main body sheet 14 is notched in a radiused shape at both ends of the second cutting lines 28. This makes it easy to grasp the position of the horizontal dividing lines 20 and to perform the separation operation. At the same time, the radiused chamfer remains even after separation, reducing the risk of injury to the user and allowing for safe use and portability.

[0034] The following describes how the blister package 10 according to this embodiment is separated into units of a predetermined number of storage sections 12. For example, when separating one (or nine) storage sections 12, the storage sections 12 can be easily separated into units of only one storage section 12 by tearing them apart using one narrow slit 24 and one second cutting line 28 on the <0>-<1> line in FIG. 5, as shown in the lower diagram of FIG. 5. Separation can also be easily achieved by a cutting operation that involves bending and stretching the second cutting line 28. Similarly, when separating two (or eight) storage sections 12 into units, the storage sections 12 can be easily separated using one narrow slit 24 and one first cutting line 22 formed in a straight line on the <0>-<2> line in FIG. Furthermore, when separating a unit of three (or seven) storage sections 12, separation can be easily achieved by using the two narrow slits 24 on the <0>-<3>-<5> line in Fig. 5 and one second cutting line 28 with both ends facing the narrow slits 24. When separating a unit of four (or six) storage sections, separation can be easily achieved by tearing apart one narrow slit 24 and one first cutting line 22 formed in a straight line on the <4>-<5> line in Fig. 5. When separating a unit of five storage sections 12, separation can be easily achieved by using the two narrow slits 24 on the <5>-<6>-<7> line in Fig. 5 and one second cutting line 28 with both ends facing the narrow slits 24.

[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 line 22 or the second cutting line 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 blister package with significantly improved cutting operability and high practicality 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 similar to the first embodiment, comprising a main body sheet 14 on which a plurality of storage compartments 12 are arranged, and a lid sheet 16, with a vertical dividing line 18 and a horizontal dividing line 20 formed on the main body sheet 14. Furthermore, the vertical dividing line 18 also has a first cutting line 22 and a narrow slit 24, and the horizontal dividing line 20 also has a second cutting line 28 whose end faces the narrow slit 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 Figure 7, a blister package 10-2 according to the second embodiment has a configuration similar to that of 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 of the second cutting line 28 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 Figure 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, the blister package 10-3 according to the third embodiment has substantially the same configuration as the first embodiment, but is slightly different in the shape of the second cutting line 28.

In this embodiment, the easily breakable portion 26 as in the first embodiment is not provided, 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 an eighth embodiment has a configuration substantially 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 substantially rounded rectangular shape that is longer in the vertical direction than in the above-described embodiment, 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 that of 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.

[0045] 15, a blister package 10-10 according to the tenth embodiment has substantially the same configuration as the eighth embodiment, but is slightly different in the shape of the vertical dividing line portion 18. In this embodiment, the easy-to-tear portion 26 is formed at the middle position in the longitudinal direction of the narrow slit portion 24, and is formed as two narrow openings: 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.

[0046] 16, the blister package 10-11 according to the eleventh embodiment has substantially the same configuration as the ninth 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.

[0047] 17, the blister package 10-12 according to the twelfth embodiment has substantially the same configuration as the eighth embodiment, but is slightly different in the shape of the vertical dividing line portion 18. In this embodiment, the easy-to-tear portion 26 is not provided, 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.

[0048] 18, the 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 Figure 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 rectangular shape with rounded corners 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 vertically arranged storage sections 12 at the upper or lower end. Therefore, the narrow slits 24 are formed longer than the first cutting line 22 to correspond to the remaining two of the three vertically arranged storage sections 12. The narrow slits 24 are 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 vertically arranged storage sections 12. The second cutting lines 28 are set perpendicular to the longitudinal direction of the narrow slits 24.

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

[0053] The blister package of the present invention can be suitably used for packaging, for example, tablets, capsules, etc. Furthermore, the blister package can be suitably used in a wide range of fields, for example, food, cosmetics, daily necessities, etc.
