Abstract
Description
[Technical field]
[0001] The present invention relates to a sachet, a sachet manufacturing apparatus, and a sachet manufacturing method. [Background technology]
[0002] In general, medicines provided at pharmacies and the like are divided into, for example, single doses and packed in bags, etc. Patent Document 1 discloses a medicine packing machine as a technology for dividing and packing medicines.
[0003] Moreover, Patent Document 2 discloses a sachet capable of separately storing a plurality of medicines. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Publication No. 56-143172 [Patent Document 2] JP 2023-073703 A Summary of the Invention [Problem to be solved by the invention]
[0005] Meanwhile, in medical facilities such as hospitals, nursing homes, pharmacies, etc., there is a demand for a system that allows patients (or facility users or consumers) to store medicines together so that they do not lose or forget to take them. In particular, when a patient needs to take multiple types of medicine, there is a concern that some of the medicines will be lost or forgotten, and the demand is even greater.
[0006] For this reason, it is conceivable to use a medicine packaging machine disclosed in Patent Document 1 or the like to separate and store medicines. However, conventional medicine packaging machines, including the one in Patent Document 1, package bare medicines directly in film, so high barrier properties of the film are essential. For this reason, conventional machines have mainly focused on high barrier properties of the film, and properties (characteristics) other than the barrier properties of the film need to be improved. In order to improve properties other than the barrier properties of the film, it is desirable to increase the degree of freedom in the film material so as to expand the range of materials that can be selected to determine the film properties.
[0007] In view of these points, an object of the present disclosure is to increase the degree of freedom in the material of the sachet. [Means for solving the problem]
[0008] A first aspect of the present disclosure is a sachet having a plurality of storage sections for packaging packaged medicine, each of the plurality of storage sections being constructed of a resin front film and a resin back film having heat-sealed sections that are heat-sealed to each other.
[0009] In this first aspect, since the sachet contains packaged medicines, not bare medicines, the sachet itself does not need to have the high barrier properties that were previously required. Therefore, various materials can be selected as the material for the sachet. In other words, there is a high degree of freedom in the material for the sachet.
[0010] A second aspect of the present disclosure is the first aspect, wherein the front film and the back film are both constructed by laminating an inner layer of the sachet made of unstretched polypropylene and an outer layer of the sachet made of biaxially oriented polypropylene.
[0011] When the front and back films are constructed by laminating an inner layer made of non-oriented polypropylene and an outer layer made of biaxially oriented polypropylene as in the second embodiment, the sachet can be easily torn by hand to remove the medicine inside. Also, when the outer layers of the front and back films are constructed of biaxially oriented polypropylene, the sachet is less prone to wrinkling, improving the design of the sachet.
[0012] A third aspect of the present disclosure is a film storage device according to the first aspect, wherein the multiple storage sections are arranged in a row, and at least one of the multiple storage sections has one or more further storage sections provided by a further film provided on at least one of the front side of the front film and the back side of the back film.
[0013] In this third embodiment, in addition to the multiple storage sections lined up in a row, one or more other storage sections are further provided on at least one of the front and back sides, making it convenient to store many medicines separately.
[0014] A fourth aspect of the present disclosure is a sachet manufacturing apparatus for manufacturing a sachet relating to any one of the first to third aspects, comprising: a base provided with a mounting portion on which the front film and the back film are placed, a lid portion capable of covering the base by sandwiching the front film and the back film placed on the mounting portion between the base and the lid portion, and a heating portion for forming the heat seal portion provided on the lid portion, the heating portion facing the mounting portion when the base is covered by the lid portion.
[0015] In the fourth aspect, a heat-sealed portion is formed in the front film and the back film, and the sachet according to any one of the first to third aspects can be produced.
[0016] A fifth aspect of the present disclosure is the fourth aspect, wherein a portion of the placement section facing the heating section is attached to the back film.
[0017] In the fifth embodiment, the portion of the mounting part facing the heating part is attached to the back film, so that the back film is less likely to shift position when the heat seal part is formed, and the sachet bag can be easily manufactured. In other words, it is easy to package multiple packaged medicines.
[0018] A sixth aspect of the present disclosure is the fifth aspect, wherein the back film is made of biaxially oriented polypropylene at least on the outer surface of the sachet, and at least the opposing portion of the placement portion is made of silicone.
[0019] In this sixth aspect, the back film, whose outer surface is made of biaxially oriented polypropylene, and the opposing portion of the mounting section made of silicone adhere to each other, thereby specifically obtaining a sachet manufacturing apparatus that exhibits the effects of the fifth aspect.
[0020] A seventh aspect of the present disclosure is a sachet manufacturing method for producing a sachet relating to any one of the first to third aspects, which includes placing the packaged medicine on the front side of the back film, placing the front film on the front side of the back film on which the packaged medicine is placed, and heating the back film and the front film to form the heat seal portion, thereby forming the multiple storage portions.
[0021] In the seventh aspect, a sachet that exhibits the effects of the first to third aspects can be manufactured by forming heat-sealed portions in the front film and the back film. Effect of the Invention
[0022] As described above, according to the present disclosure, there is greater freedom in the material used for the sachet. [Brief description of the drawings]

[Diagram 3]1 is a perspective view showing a sachet manufacturing apparatus according to an embodiment; [Figure 4] 4 is an enlarged perspective view showing the periphery of a right end portion of the device shown in FIG. 3. [Diagram 5] FIG. 4 is a view corresponding to FIG. 2 and relating to a modified example of the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] (Embodiment) -Saving bags- Fig. 1 shows a sachet 10 according to an embodiment. The sachet 10 has multiple storage sections S1, S1, ... for dividing and packaging multiple packaged medicines, for example, by daily doses. Fig. 1 shows three types of packaged medicines M1 to M3 as an example. The medicines M1 to M3 may be packaged in any form (for example, tablet, capsule, powder) as long as they are packaged in a film, medicine packaging (PTP), or other packaging material.
[0025] The multiple storage sections S1, S1, ... are arranged in a row as shown in Fig. 1. The number of storage sections S1, S1, ... is not limited, but it is preferable that there are seven storage sections so that the user can separate the seven days' worth of medicine to be taken in one week by day.
[0026] The sachet 10 has a front film F1 and a back film F2 made of resin. The front film F1 and the back film F2 have a heat-sealed portion 11 that is heat-sealed to each other, thereby forming each storage section S1. The heat-sealed portion 11 is formed in a rectangular shape surrounding each storage section S1. The shape of each storage section S1 is not particularly limited, but is preferably a square with a side length of 60 mm to 100 mm. The line width of the heat-sealed portion 11 is, for example, 2 mm or more and 3 mm or less. The thickness of both films F1 and F2 is, for example, 50 μm.
[0027] Between adjacent storage sections S1, S1, perforations 12 (broken line slits) are formed extending in the width direction of the sachet 10 so as to facilitate separation of the storage sections S1, S1 from each other. In Fig. 1, the front side of the paper is the front side, and the back side of the paper is the back side. One cut section 13 is formed in each storage section S1 at one end in the width direction of the front film F1 and the back film F2 for tearing the sachet 10 to take out the drugs M1 to M3.
[0028] The materials of the front film F1 and the back film F2 are not limited, but as described in detail below, from the viewpoint of making the sachet 10 easier to manufacture, it is preferable that the inner layer of the sachet 10 made of unoriented polypropylene (CPP) and the outer layer of the sachet 10 made of biaxially oriented polypropylene (OPP) are laminated together.
[0029] -Saving bag manufacturing equipment- 3 shows a sachet manufacturing apparatus 20 according to an embodiment. The sachet manufacturing apparatus 20 (hereinafter referred to as the "manufacturing apparatus") is for manufacturing the sachet 10 by forming a heat seal portion 11 in the front film F1 and the back film F2. The manufacturing apparatus 20 is also a medicine packaging machine since it can package a plurality of medicines by manufacturing the sachet 10.
[0030] The manufacturing apparatus 20 includes a base 22 having a placement portion 21 on the upper portion of which the front film F1 and the back film F2 are placed when manufacturing the sachet 10. The base 22 is formed in a generally rectangular parallelepiped shape that is long in the left-right direction of Fig. 3 (the longitudinal direction of the sachet 10). A plate portion B1 that is long in the left-right direction of Fig. 3 is provided on the upper surface of the base 22, and the placement portion 21 is provided on the upper surface of the plate portion B1. The plate portion B1 has electrical insulation and heat insulation properties.
[0031] When the sachet 10 is manufactured, the mounting portion 21 contacts the heat-sealed portion 11 of the sachet 10 from below to support the sachet 10. The mounting portion 21 is formed in a shape corresponding to the shape of the heat-sealed portion 11. Specifically, the mounting portion 21 is configured by arranging a plurality of (e.g., seven) rectangular frame portions surrounding one storage portion S1 side by side in the left-right direction of Fig. 3. When at least the outer surface of the back film F2 of the sachet 10 is configured from biaxially oriented polypropylene, the mounting portion 21 is preferably configured from silicone from the viewpoint of facilitating adhesion to the back film F2.
[0032] The manufacturing apparatus 20 includes guide portions 23, 23 for guiding the front film F1 and the back film F2 in the width direction of the sachet 10 so that they are positioned on the mounting portion 21 when manufacturing the sachet 10. The guide portions 23, 23 are provided on the left side of the left end of the mounting portion 21 and on the right side of the right end of the mounting portion 21, and each guide portion 23 is made up of a pair of resin members or metal members that sandwich the position where both films F1, F2 are to be positioned. The pair of resin members (or metal members) constituting each guide portion 23 are each formed in a substantially L-shape when viewed in the left-right direction of FIG.
[0033] The manufacturing device 20 includes fixing parts 24, 24 for fixing both longitudinal ends of the front film F1 and the back film F2 when manufacturing the sachet 10. One fixing part 24, 24 is provided on the left side of the left guide part 23 and one on the right side of the right guide part 23. Each fixing part 24 is formed in a rod shape extending in the width direction of both films F1, F2 so that it can press and fix both films F1, F2 from above. A cutter 25 that can slide in the extension direction of the fixing part 24 is provided on the left side surface of the left fixing part 24. The cutter 25 is configured to slide to cut the front film F1 and the back film F2.
[0034] The manufacturing device 20 includes a lid portion 26 that can cover the base portion 22. The lid portion 26 is provided to be rotatable relative to the base portion 22 around a rotation axis R configured by a hinge or the like. The rotation axis R is provided between the base portion 22 and the lid portion 26 at one end of the base portion 22 in the width direction (the end side of the sachet 10 in the width direction), and extends in the left-right direction in FIG. 3. When the lid portion 26 covers the base portion 22 (i.e., when the lid portion 26 is closed) in a state in which the front film F1 and the back film F2 are placed on the placement portion 21, the lid portion 26 sandwiches the front film F1 and the back film F2 placed on the placement portion 21 between the base portion 22 and the lid portion 26. At the left-right center of the outer side of the lid portion 26 and the left-right center of the outer side of the base portion 22, as shown in FIG. 3, a lid fixing portion L for fixing the closed lid portion 26 to the base portion 22 is provided.
[0035] The manufacturing apparatus 20 includes a heating section 27 provided on the lid section 26 for forming the heat-sealed section 11 in the sachet 10. The heating section 27 faces the placement section 21 from above with the lid section 26 covering the base section 22. Specifically, the heating section 27 is configured by arranging a plurality of (e.g., seven) rectangular frame sections surrounding one storage section S1 side by side in the left-right direction of FIG. 3. The heating section 27 is made of metal (e.g., SUS or nichrome). A plate section B2 that is long in the left-right direction of FIG. 3 (the longitudinal direction of the sachet 10) is provided between the lid section 26 and the heating section 27. The plate section B2 has electrical insulation and heat insulation properties.
[0036] In addition, in a state in which the lid portion 26 is fixed to the base portion 22 by the lid fixing portion L, both films F1, F2 are sandwiched between the lid portion 26 (heating portion 27) and the base portion 22 and pressed with a pressure of about 0.1 MPa.
[0037] The heating section 27 has a resistance so as to generate heat by electricity supplied from a power source. From the viewpoint of adequately melting and fusing the unstretched polypropylene portions of the front film and the back film to each other in a short time (e.g., 4 seconds), the magnitude of the resistance is preferably 2.1Ω to 2.9Ω per frame, more preferably 2.6Ω to 2.9Ω, and particularly preferably 2.7Ω. That is, when the heating section 27 is composed of seven frames as shown in FIG. 3, the resistance of the entire heating section 27 is preferably 15Ω to 20Ω, more preferably 18Ω to 20Ω, and particularly preferably 18Ω to 19Ω (e.g., 18.9Ω). If the resistance of heating unit 27 is within this range, a current of about 6 to 7 A will likely cause heating unit 27 to reach approximately 90 to 120° C. within, for example, 4 seconds, and more specifically, the side closer to heating unit 27 (front film F1) will likely reach approximately 120° C., and the side closer to mounting unit 21 (rear film F2) will likely reach approximately 90 to 100° C. If the current flowing through heating unit 27 is about 6 to 7 A, it will be possible to use a general outlet that can pass a current of 15 A or less, which is preferable from the viewpoint of increased versatility.
[0038] 4, the manufacturing apparatus 20 is provided with sawtooth-shaped perforation forming units 28, 28, ... for forming perforations 12, 12, ... in the sachet 10 when manufacturing the sachet 10. Each perforation forming unit 28 is provided in the lid unit 26, one at each of the left and right ends of each frame portion constituting the heating unit 27.
[0039] 4, the manufacturing apparatus 20 is provided with blades 29, 29, ... for forming the incisions 13, 13, ... in the sachet 10 when manufacturing the sachet 10. Each blade 29 is provided below each frame portion (heating portion 27) in the state shown in FIGS. 3 and 4 (with the lid portion 26 open) so as to form one incision 13 at one end of each storage portion S1 in the width direction.
[0040] As shown in Fig. 3, the manufacturing apparatus 20 includes a first film roll FR1 from which the front film F1 is fed and a second film roll FR2 from which the back film F2 is fed. Both film rolls FR1 and FR2 are arranged side by side in the left-right direction on the left side of the left end of the base 22. The first film roll FR1 is arranged to the left of the second film roll FR2 and at a position slightly higher than the second film roll FR2 so that the front film F1 can be easily positioned above the back film F2. A support plate SP is provided at the left end of the base 22 to support both films F1 and F2 so that both films F1 and F2 fed from the film rolls FR1 and FR2 are stably positioned on the mounting unit 21.
[0041] -Saving bag manufacturing method- In the manufacturing method of the sachet 1 according to the embodiment, the sachet 10 is manufactured using, for example, the manufacturing apparatus 20. Specifically, the manufacturing method is as follows.
[0042] 3, the first film roll FR1 and the second film roll FR2 are set in the manufacturing device 20, and the lid portion 26 is opened. Next, the front film F1 and the back film F2 are unwound from the first film roll FR1 and the second film roll FR2, respectively, to the inside in the width direction of both guide portions 23, 23 so as to spread across the entire loading portion 21. Next, the left and right end portions of both films F1, F2 are fixed by the fixing portions 24, 24.
[0043] Next, the lid portion 26 is closed to place the heating portion 27 opposite the mounting portion 21 with both films F1, F2 sandwiched therebetween. The closed lid portion 26 is fixed with the lid fixing portion L so that the entire heating portion 27 presses both films F1, F2 and the mounting portion 21 with a uniform pressing force. When the lid portion 26 is closed, perforations 12, 12, ... are formed in both films F1, F2 by the perforation forming portions 28, 28, ..., and incisions 13, 13, ... are formed by the blades 29, 29, ....
[0044] Next, the power switch SW (see FIG. 3) provided on the base 22 is turned on to heat the heating unit 27 and form the heat-sealed portion 11 in both films F1, F2. The heat-sealed portion 11 is formed approximately 4 seconds after the heating unit 27 starts to generate heat, and then the lid 26 is opened and the cutter 25 is slid to cut both films F1, F2 at their left ends, thereby obtaining the manufactured sachet 10.
[0045] In addition, the manufacturing method of the sachet 10 of the present invention does not necessarily require the use of the manufacturing apparatus 20, but rather involves placing a packaged medicine on the front side of the back film F2, placing a front film F1 on the front side of the back film F2 on which the packaged medicine is placed, and heating the back film F2 and the front film F1 to form a heat seal portion 11, thereby forming multiple storage sections S1, S1, ....
[0046] --Action and Effects-- In conventional sachets, bare medicines are directly packaged, so the barrier properties of the sachets must be high, and cellophane, glassine paper, etc. are generally used as materials for the sachets. However, although such conventional sachets have high barrier properties, there is room for improvement in other characteristics (properties), such as ease of handling, design, ease of manufacture, etc.
[0047] In the sachet 10 according to the present embodiment, a packaged drug is stored instead of an uncovered drug, so the sachet 10 itself does not need to have the high barrier properties that were previously required. Therefore, various materials can be selected as the material for the sachet 10. In other words, the degree of freedom in the material for the sachet 10 is increased. As a result, the range of materials that determine the properties of the sachet 10 can be selected is widened, making it easier to improve properties other than the barrier properties.
[0048] When the outer layers of the front film F1 and the back film F2 are made of biaxially oriented polypropylene as in the sachet 10 according to this embodiment, the sachet 10 can be easily torn by hand in order to take out the medicine inside the sachet 10. In other words, the sachet 10 becomes easier to handle.
[0049] In addition, since the outer layers of the front film F1 and the back film F2 are made of biaxially oriented polypropylene, they are less likely to wrinkle, and the design of the sachet 10 is improved.
[0050] 3, the placement section 21 (multiple frame sections) on which the films F1, F2 are placed when the heat-sealed section 11 of the sachet 10 is formed is elevated above the plate section B1 that serves as its base. In this configuration, the back film F2 that is placed directly on the placement section 21 may be displaced from its ideal position, which may result in the heat-sealed section 11 not being formed correctly on the films F1, F2.
[0051] Here, in the manufacturing apparatus 20 according to this embodiment, the portion of the mounting unit 21 facing the heating unit 27 is made of silicone and adheres to the back film F2 whose outer surface is made of biaxially oriented polypropylene, so that the back film F2 is less likely to shift position when the heat seal portion 11 is formed, and it becomes easier to manufacture the sachet 10. In other words, it becomes easier to package a plurality of packaged medicines.
[0052] Incidentally, if the sachet 10 is made of a material used for conventional sachet bags (cellophane, glassine paper, etc.), it is necessary to raise the temperature of both films F1, F2 generated by the heating unit 27 to a temperature higher than the above-mentioned 90 to 120° C. (for example, 130° C.) when forming the heat-sealed portion 11. In this case, if the portion of the mounting unit 21 facing the heating unit 27 is made of silicone as in this embodiment, there is a risk that the high heat temperature of the heating unit 27 will cause the facing portion of the mounting unit 21 to melt.
[0053] In this embodiment, since the inner layers of both films F1, F2 of the sachet 10 are made of unstretched polypropylene, the heat-sealed portion 11 can be formed in both films F1, F2 even if the temperature of both films F1, F2 caused by the heat generated by the heating unit 27 is about 90 to 120°C. In this way, when the inner layers of both films F1, F2 of the sachet 10 are made of unstretched polypropylene, the heat-sealed portion 11 can be formed at about 90 to 120°C, at which the silicone mounting portion 21 is unlikely to melt. Furthermore, if the heat generated by the heating unit 27 is too high, both films F1, F2 made of biaxially oriented polypropylene may adhere to the heating unit after welding, making them difficult to handle. However, if the heat generated by the heating unit 27 causes the temperature of both films F1, F2 to be about 90 to 120°C, such a problem is unlikely to occur.
[0054] Furthermore, since the manufacturing apparatus 20 according to this embodiment is equipped with the blades 29, 29, ..., it is possible to manufacture the sachet 10 and form the incisions 13, 13, ... in the sachet 10 to make it easier to tear, thereby manufacturing the sachet 10 that can be easily torn to make it easier to take out the medicine inside. If the above-mentioned incisions are formed in a conventional sachet in which the bare medicine is directly contained, it is no longer possible to maintain high barrier properties.
[0055] (Modification of the embodiment) As shown in Fig. 5, the sachet 10 may be provided with one or more additional storage sections S2 (further storage sections) different from the multiple storage sections S1, S1, ... arranged in a row in at least one of them. The additional storage section S2 is formed by a further film F3 provided on at least one of the front side of the front film F1 and the back side of the back film F2. For example, as shown in Fig. 5, the film F3 may be provided on the front side of the front film F1, and this film F3 and the front film F1 may be heat-sealed to form the additional storage section S2.
[0056] In this modified example, in addition to the multiple storage sections S1, S1, ... arranged in a row, one or more other storage sections S2 are further provided on the front side, so that many medicines can be stored separately, which is convenient. For example, the medicine to be taken in the morning can be stored in storage section S1, and the medicine to be taken in the evening can be stored in storage section S2, which increases the freedom of how to separate the medicines.
[0057] The storage section S2 may be provided on the rear side of the storage section S1.
[0058] (Other embodiments) The number of storage sections S1 in the sachet 10 is not limited to seven as exemplified in the description of the embodiment, and may be more than one. In the embodiment, the configuration in which seven storage sections S1 are arranged in a row in the left-right direction of FIG. 1 is exemplified, but the storage sections S1 may be arranged in multiple rows of seven rather than one row of seven. For example, seven storage sections S1, S1, ... may be arranged in three rows so that the drugs to be taken in the morning, afternoon, and evening of each day of the week are divided into 7 x 3. Alternatively, in the sachet 10 according to the modification including the storage section S1 and the storage section S2, a total of 7 x 3 storage sections may be configured by providing additional storage sections (not shown) other than the storage sections S1 and S2 on the back side of the storage section S1 or the front side of the storage section S2.
[0059] In the above embodiment, the mounting portion 21 is made of silicone, but only the portion facing the heating portion 27 may be made of silicone. The mounting portion 21 may be made of a material other than silicone. An adhesive portion may be provided on the upper surface of the mounting portion 21 (the portion facing the heating portion 27) to impart adhesive force so that the mounting portion 21 can easily adhere to the back film F2 made of any material.
[0060] In the above embodiment, the front film F1 and the back film F2 have an inner layer made of non-oriented polypropylene and an outer layer made of biaxially oriented polypropylene, but the front film F1 and the back film F2 may be made of any resin. The front film F1 and the back film F2 are preferably made of a material that can form the heat seal part 11 at a temperature of less than 130° C. at which the silicone mounting part 21 does not easily melt, and are preferably made of a material that adheres to the silicone mounting part 21 during manufacturing.
[0061] In the embodiment, the heat-sealed portion 11 is formed in a rectangular shape as shown in Fig. 1, but the shape of the heat-sealed portion 11 does not have to be rectangular, and may be circular, triangular, etc. In addition, the storage portion S1 does not necessarily have to be heat-sealed all around as shown in Fig. 1, and a portion of the storage portion S1 may be an opening that is not heat-sealed so that the packaged drug can be easily removed from the sachet 10, and further, an opening means such as a zipper may be provided at the opening.
