Description

The present invention relates to a medicine packaging machine for packaging medicines dispensed based on a doctor's prescription at a hospital or a pharmacy with a medicine wrapping paper for each dose, and a medicine wrapping paper or a sachet used for the medicine packaging. is there.

  Conventionally, when a drug dispensed according to a prescription is given to a patient, it is necessary for a single dose with an automatic drug packaging machine etc. so that the patient does not have to take a combination of different drugs each time. The medicine is packaged in the same sachet (see Patent Document 1).

  As the material of the medicine bag, a packaging sheet (glassine) that is easy to handle with an automatic medicine packaging machine, has high internal visibility and is easy to audit dispensing, and is excellent in opening (ease of opening) of the packaging bag. Recently, packaging sheets such as polyethylene laminated cellophane paper or polyethylene laminated glassine paper have been widely used.

JP-A-8-11805

However, since cellophane and the like are expensive, recently, polypropylene and polyethylene terephthalate that can be contacted with food and have been confirmed to be safe have been used as materials for medicine bags.

  However, if the sachet is made from polypropylene or polyethylene terephthalate, etc., conventional glassine paper or cellophane paper is used for ease of handling and dispensing audits during drug sachets. Although it is not inferior to that of the case, it was difficult for elderly people and children to open the sachets and how to open them, and there was a problem in handling.

  The present invention has been made to solve the conventional technical problems, and the object of the present invention is to wrap a medicine dispensed based on a doctor's prescription with a medicine wrapping paper for each dose. It is an object of the present invention to provide a medicine packaging machine that can be easily opened even by an elderly person or a child, and to provide a medicine wrapping paper and a sachet formed thereby.

In other words, a medicine packaging machine for packaging with medicine wrapping paper uses a band-shaped medicine wrapping paper, and wraps medicine by making a plurality of sachets that are separated while taking medicine in a state where the medicine is stored inside. The raw material of the medicine wrapping paper is a strip-shaped transparent composite plastic sheet including a polyethylene terephthalate sheet or a biaxially stretched polypropylene sheet, and fine scratches are formed on the polyethylene terephthalate sheet or the biaxially stretched polypropylene sheet. Yes.

  In addition, the medicine packaging machine uses a band-shaped medicine wrapping paper, and wraps the medicine by making a plurality of sachet bags that are continuously separated in the state in which the medicine is stored inside, and is separated from the medicine packaging paper. The raw material is a band-like transparent composite plastic sheet including a polyethylene terephthalate sheet or a biaxially stretched polypropylene sheet, and both side edge portions are formed in a wavy shape or a saw blade shape that overlaps each other when folded in half, They are welded together.

Moreover, the drug packaging machine, and rafter heat welded side edge portions of the strip of paraffin paper, and, to bag making a packing bag by heat sealing a strip of predetermined width in the longitudinal direction and orthogonal direction of the powder paper At the same time, the sachet is characterized in that it is configured so as to be continuous and separable at the time of taking in a state where the medicine is accommodated therein.

According to the medicine packaging machine, powder paper, for example, in that handling and dispensing audit ease during drug packaging, no favorably slightly as compared with the case of using such conventional glassine paper and cellophane paper Since it is cut into a predetermined width and wound up, it can be applied to a conventional automatic medicine packaging machine. That is, there is no need to manufacture or purchase a new or dedicated automatic medicine packaging machine.

  In addition, even elderly people and children can easily open the sachet with bare hands, so guide the packaged medicine along the folded part (unwelded part) instead of the welded part. Thus, even if it is a fine particle such as a powder, it is possible to reliably take it without leaving it, so that an operational effect excellent in effectiveness can be obtained.

Further, the medicine wrapping paper of the present invention is a belt-like one for making a plurality of sachets that are continuous in a state in which a medicine is contained therein and separated at the time of taking, and the raw material is a plastic sheet. In addition, both side edge portions are formed with triangular cuts that overlap each other when folded in two, and are welded to each other, so that when the medicine stored in the sachet is taken out The sachet can be opened along the notch of the plastic sheet. As a result, for example, even a sachet made of a plastic sheet that is difficult to cut compared to a conventionally used packaging sheet such as polyethylene laminated cellophane paper or polyethylene laminated glassine paper is easily cut from a desired cutting position. It becomes possible. Therefore, even a senior citizen or a child, especially a sick person with weak hand strength, can easily open the sachet with bare hands.

  Further, when folded in half, the cuts at the side edge portions substantially coincide with each other, so that the force to cut into the cut portions provided at the side edge portions of the sachet bag is easily concentrated. Thereby, it becomes possible to cut open the packaging bag from the cut portion even with a relatively weak force. Therefore, even an elderly person or a child, especially a sick person with weak hand strength, can easily cut out the plastic sheet from the cuts at both side edges of the folded folding bag. .

  Furthermore, since the cuts at the side edge portions are shifted from each other when folded in half, when the sachet is cut from the cut portions provided at the both side edges of the medicine wrapping paper, It can be shifted. Thereby, it becomes possible to make it easy to open the sachet from the end portion that has been opened by shifting the sachet. Therefore, the medicine in the sachet can be taken out very easily.

  In addition, since the angle formed by the opposite hypotenuses of the triangular cut is 110 degrees or less, the plastic sheet is difficult to tear from the cut when the plastic sheet is pulled in the drug packaging process in the drug packaging machine. When opening the sachet, the triangular cutting angle is too large, and for example, the patient does not easily concentrate the force to open the sachet. Thereby, it can use suitably for the packaging of the medicine with a medicine packaging machine, and it becomes possible to provide a triangular cut that allows the patient to easily open the packaging bag.

  Further, since the triangular cut bottom has a curved shape with a radius of 2 μm to 10 μm, the cut does not protrude from the bottom when the cut is formed. Thereby, it becomes possible to prevent any inconvenience that the medicine is scattered from the inside of the packing bag by tearing the packing bag in a direction contrary to the intention.

  In addition, since the medicine is packaged by using a belt-shaped medicine wrapping paper and by making a plurality of sachets separated continuously at the time of taking the medicine inside, the plastic sheet stage, It becomes possible to form notches at both side edges. Thereby, it becomes possible to easily form cuts in all the continuous sachets. Therefore, the cost of the packaging bag in which the medicine is stored can be greatly reduced.

  In addition, the side edge of the belt-shaped medicine wrapping paper is welded with a palm, and is heat-sealed in a belt shape having a predetermined width in the direction perpendicular to the longitudinal direction of the medicine wrapping paper, and is continuously in a state in which the medicine is housed inside, Since it is configured to be separable at the time of taking and the portion where the cut is formed is not thermally welded, it is possible to prevent the raw material of the medicine-wrapped paper melted from the triangular cut portion from leaking out. . As a result, it is possible to prevent inconveniences such as adhesion of the raw material for the medicine-wrapping paper leaking to the medicine packaging machine and deterioration of the appearance of the packaging bag.

  In addition, since the joint heat welding location is separated from the bottom of the cut by 0.5 mm to 1.0 mm, for example, it is effective that the raw material of the melted medicine wrapping paper leaks to the triangular cut end. Can be prevented. Thereby, it becomes possible to prevent inconveniences such as the side edge of the medicine-wrapping paper sticking to the medicine packaging machine. Therefore, it is possible to prevent the performance of the medicine packaging machine from deteriorating.

  Moreover, since a medicine is packaged by making a sachet, the performance of the medicine packaging machine can be greatly improved. Therefore, the convenience of the medicine packaging machine can be greatly improved.

As described above in detail, according to the medicine packaging machine of the present invention, the medicine wrapping paper uses, for example, conventional glassine paper, cellophane paper, etc. in terms of handling at the time of medicine packaging and ease of dispensing inspection. Compared to the above, there is no fading, and it is cut into a desired width and wound up, so that it can be applied to a conventional automatic medicine packaging machine. That is, there is no need to manufacture or purchase a new or dedicated automatic medicine packaging machine.

  In addition, even elderly people and children can easily open the sachet with bare hands, so guide the packaged medicine along the folded part (unwelded part) instead of the welded part. Thus, even if it is a fine particle such as a powder, it is possible to reliably take it without leaving it, so that an operational effect excellent in effectiveness can be obtained.

  Further, it is a belt-like one for making a plurality of sachets that are continuously stored with medicines inside and separated at the time of taking, and the raw material is a plastic sheet, and both side ends The edge is formed with triangular cuts that overlap each other when folded in half, and in the case of heat-welded with each other, the plastic sheet cuts when taking out the medicine stored in the packing bag. A sachet can be opened along. As a result, for example, even a sachet made of a plastic sheet that is difficult to cut compared to a conventionally used packaging sheet such as polyethylene laminated cellophane paper or polyethylene laminated glassine paper is easily cut from a desired cutting position. It becomes possible. Therefore, even a senior citizen or a child, especially a sick person with weak hand strength, can easily open the sachet with bare hands.

  Further, when folded in half, the cuts at the side edge portions substantially coincide with each other, so that the force to cut into the cut portions provided at the side edge portions of the sachet bag is easily concentrated. Thereby, it becomes possible to cut open the packaging bag from the cut portion even with a relatively weak force. Therefore, even an elderly person or a child, especially a sick person with weak hand strength, can easily cut out the plastic sheet from the cuts at both side edges of the folded folding bag. .

  Furthermore, since the cuts at the edge portions on both sides are shifted when folded in half, the opened end portion of the packing bag can be shifted. Thereby, it becomes possible to make it easy to open the packaging bag from the end portion that has been opened and shifted. Therefore, the medicine in the sachet can be taken out very easily.

  In addition, since the angle formed by the opposite hypotenuses of the triangular cut is 110 degrees or less, the plastic sheet is difficult to tear from the cut when the plastic sheet is pulled in the drug packaging process in the drug packaging machine. When opening the sachet, the triangular cutting angle is too large, and for example, the patient does not easily concentrate the force to open the sachet. Thereby, it can use suitably for the packaging of the medicine with a medicine packaging machine, and it becomes possible to provide a triangular cut that allows the patient to easily open the packaging bag.

  Further, since the triangular cut bottom has a curved shape with a radius of 2 μm to 10 μm, the cut does not protrude from the bottom when the cut is formed. Thereby, it becomes possible to prevent any inconvenience that the medicine is scattered from the inside of the packing bag by tearing the packing bag in a direction contrary to the intention.

  In addition, since the medicine is packaged by making a plurality of sachets that are continuously separated while taking the medicine inside, the notches are formed on both side edges at the plastic sheet stage. It will be possible to keep. Thereby, it becomes possible to easily form cuts in all the continuous sachets. Therefore, the cost of the packaging bag in which the medicine is stored can be greatly reduced.

  In addition, the side edge of the belt-shaped medicine wrapping paper is welded in a palm-shaped manner and welded in a belt shape with a predetermined width in the direction perpendicular to the longitudinal direction of the medicine wrapping paper. Since the portion that is sometimes separable and the cut is formed is not thermally welded, it is possible to prevent the raw material of the medicine-wrapped paper melted from the triangular cut portion from leaking out. As a result, it is possible to prevent inconveniences such as adhesion of the raw material for the medicine-wrapping paper leaking to the medicine packaging machine and deterioration of the appearance of the packaging bag.

  In addition, since the joint heat welding location is separated from the bottom of the cut by 0.5 mm to 1.0 mm, for example, it is effective that the raw material of the melted medicine wrapping paper leaks to the triangular cut end. Can be prevented. Thereby, it becomes possible to prevent inconveniences such as the side edge of the medicine-wrapping paper sticking to the medicine packaging machine. Therefore, it is possible to prevent the performance of the medicine packaging machine from deteriorating.

  Moreover, since a medicine is packaged by making a sachet, the performance of the medicine packaging machine can be greatly improved. Therefore, the convenience of the medicine packaging machine can be greatly improved.

As shown in FIG. 6, the medicine wrapper mounting means includes a rotary shaft 16 that is rotatably provided on a base 15, and a disk-shaped mounting plate 17 that is located at the bottom of the rotary shaft 16 and projects outward. , And a solenoid-driven brake 18 disposed on the lower side (between the base 15) of the mounting plate 17 and the like.

  The rotating shaft 16 has a cylindrical shape having an outer diameter that substantially matches (is smaller than that) an inner diameter of a shaft member 21 of a medicine-wrapping paper roll 19 described later, and the rotating shaft 16 is formed on the medicine-wrapping paper roll 19. The shaft 21 is detachably inserted. Here, the medicine-wrapping roll 19 is composed of a hollow tubular shaft material (usually referred to as a paper tube) 21 made of hard synthetic resin (may be made of thick paper) and the medicine-wrapping paper 20 wound around it. (FIGS. 7 and 8). The medicine-wrapping paper 20 is provided by winding a vertically long strip having a predetermined width around the shaft 21 in a roll shape.

  Then, as described above, the medicine wrapper 20 is folded in half from the substantially central portion in the width direction, and the double folded portion is folded into the folded portion 20A, and both folded end portions (folded portions). The opening 20B is formed on the side opposite to 20A. The medicine-wrapping paper 20 is wound around the shaft member 21 with the folded portion 20A being the lower end edge side of the shaft member 21 in a double-folded state, and is drawn out from the final end of the wound medicine-wrapping paper 20 (FIG. 9).

  The medicine packaging mechanism 14 is provided with a tension lever 23 as a guide means located on the side of the rotation shaft 16, and the tension lever 23 is passed between two rollers 24 and 25. At this time, the roller 24 is fixed to the base 15, and the roller 25 is swingable about the roller 24. The roller 25 is urged in a direction away from the rotating shaft 16 by a spring material (not shown). The position of the roller 25 is detected by a switch (not shown). Reference numeral 26 denotes a guide roller, which is erected on the base 15 on the side of the roller 24.

  A pull-in roller 30 as a pull-in means is provided on the base 15 on the opposite side across the tension lever 23 and the rotating shaft 16. The drawing roller 30 is composed of a pair of narrow rubber rollers (natural rubber or synthetic rubber) 33, 33A, and is rotatably attached to the upper ends of the rotary shafts 32, 34. The rotating shaft 32 to which one rubber roller 33 is attached is the rotating shaft of the retracting motor 31.

  Further, the rotating shaft 34 of the other rubber roller 33A is urged by a coil spring or the like (not shown), one rubber roller 33A is pressed against the rubber roller 33 with a predetermined pressure, and both the rubber rollers 33, 33A rotate as the pulling motor 31 rotates. Is configured to do. The medicine-wrapping paper 20 (the opening 20B side) is sandwiched between the rubber rollers 33 and 33A, whereby the medicine-wrapping paper 20 is pulled out from the medicine-wrapping paper roll 19.

  A heat seal mechanism 27 is provided between the guide roller 26 and the drawing roller 30 (FIG. 10). The heat seal mechanism 27 seals the opening 20B of the medicine wrapper 20 by joint heat welding and partitions it into a single piece, and a pair of temporary heaters 28, 28 provided facing each other at a predetermined interval. , And a pair of main heaters 29, 29. Further, either one of the temporary heaters 28 and the main heater 29 is provided with an operating device (not shown), and is configured to be capable of being in pressure contact with or separated from the one of the temporary heaters 28 and the main heater 29 facing each other. When each temporary heater 28 and the main heater 29 are energized, they generate heat to a predetermined temperature.

  The main heaters 29 and 29 are each composed of vertical portions 29A and 29A and parallel portions 29B and 29B. The parallel portion 29B has substantially the same width as the temporary heater 28, and the vertical portion 29A is parallel portion 29B. It is twice the width. And it heat-welds from the folding part 20A side of the medicine packing paper 20 to the approximate middle of the opening part 20B by pinching and heating from the both sides of the medicine packaging paper 20 with the temporary heater 28 (solid line arrow range in FIG. 10 does not heat-fix).

  Further, the vertical portion 29A of the main heater 29 is fixed by heat welding from the folded portion 20A side of the medicine wrapper 20 to the opening portion 20B with the upper side heated and welded by the temporary heater 28 sandwiched from both sides. A small bag 36A provided with the portion 20B is formed on the temporary heater 28 side. The parallel portion 29B is configured to thermally weld the opening 20B opposite to the temporary heater 28 (in this case, the dimension between the main heater 29 and the temporary heater 28).

  After the medicine wrapper 20 is thermally welded by the heat seal mechanism 27, the drawing roller 30 is rotated by a predetermined distance toward the drawing roller 30 (in the direction indicated by the arrow in FIG. 10), that is, the portion thermally welded by the temporary heater 28. It moves to the main heater 29 (from the folded portion 20A to the opening 20B to the heat welded portion of the main heater 29). Then, the medicine wrapper 20 is thermally welded by the main heater 29, thereby forming a small bag 36A having an opening 20B between the temporary heater 28 and the vertical portion 29A of the main heater 29, and a folding portion on the drawing roller 30 side. It is configured to form a sachet 36 that is heat-sealed except for 20A.

  Further, when the main heater 29 is thermally welded from the folded portion 20A to the opening 20B of the medicine wrapper 20 on the temporary heater 28, the main heater 29 is perforated at substantially the center of the width of the heat-welded portion (from the folded portion 20A to the opening 20B). A cut having a plurality of 37 (perforated holes) is formed. Thereby, the three sides of the medicine wrapping paper 20 (the other one is the folded portion 20A) are thermally welded to form a sachet 36 whose entire circumference is closed, and can be separated from the perforation 37 and separated. It is configured as follows.

  Next, the operation procedure and operation of the medicine packaging machine 1 according to the present invention will be described. First, the medicine wrapper paper roll 19 is placed on the placement plate 17 while the rotary shaft 16 is inserted into the shaft member 21 of the medicine wrapper paper roll 19. At this time, the folded portion 20A is inserted into the rotating shaft 16 in a state where the folded portion 20A is positioned on the mounting plate 17 side. As described above, the medicine-wrapping roll 19 is formed by folding the medicine-wrapping paper 20 in half and winding it around the shaft member 21. Since the medicine-wrapping roll 19 includes the folding portion 20A and the opening 20B, the medicine-wrapping paper roll 19 is turned upside down. When mounted, the folding part 20A and the opening part 20B are reversed, and the medicine packaging mechanism 14 cannot package the medicine.

  After the medicine wrapper roll 19 is mounted on the rotary shaft 16 in this way, the medicine wrapper 20 of the medicine wrapper roll 19 is pulled out from the tip, sequentially passes the outside of the rollers 25 and 24 of the tension lever 23, passes through the inside of the guide roller 26, and then continues. After passing between the temporary heater 28 and the main heater 29 (the shout 13 has been tilted), it is drawn to the drawing roller 30 (FIG. 9).

  When the leading end of the medicine wrapper 20 is inserted between the rubber rollers 33 and 33A of the drawing roller 30 and the drawing motor 31 is driven, the medicine wrapper 20 is pressed against the heat seal mechanism 27 while being pressed against the rubber rollers 33 and 33A (front side). Since it is pulled in the (side) direction, the medicine-wrapping paper 20 is drawn into the drawing roller 30 and pulled out to the near side.

  Here, the roller 25 of the tension lever 23 moves in the direction of the rotating shaft 16 when the tension of the medicine wrapper 20 becomes strong, and moves in a direction away from the rotating shaft 16 when the tension becomes weak. The movement of the roller 25 is detected by the switch as described above. When the roller 25 is separated from the rotating shaft 16, the solenoid is driven by a control device (not shown), and the brake 18 is pressed against the mounting plate 17. Then, when the roller 25 moves in the direction of the rotary shaft 16, the brake 18 is now separated. Accordingly, the medicine wrapper 20 drawn out from the medicine wrapper roll 19 is configured so that appropriate tension is always applied.

  When the medicine packaging machine 1 loaded with the medicine wrapper roll 19 on the rotary shaft 16 and withdrawing and loading the medicine wrapper 20 is operated, the count value for counting the number of drops of medicine is reset. In addition, the temporary heater 28 and the main heater 29 are heated to a predetermined temperature, and the turntable 10 is energized and is always rotating. When the operator inputs prescription data into an input device (such as a personal computer) (not shown) based on the doctor's prescription, the discharge drum of the tablet case 6 in which the medicine is stored is rotationally driven and designated by the prescription data. Each kind of medicine falls onto the turntable 10 one by one. Similarly, the medicine from the sub-housing unit 7 falls on the turntable 10 in the same manner by a user's arbitrary operation.

  The number of medicines falling from the tablet case 6 is counted by a control device (not shown) based on the output of the photosensor. When the counted number of medicines falls on the number of medicines based on the prescription data, the discharge drum is rotated. Stop and end the drug fall. The medicine (including the medicine from the sub-storage unit 7) dropped on the turntable 10 is moved and collected in the direction of the outer guide 11 by the centrifugal force of the rotating turntable 10, and is discharged from the guide 11. It falls into the Schwannau 13 below the exit D. As a result, the medicine passes through the inside of the shroud 13 and is put into the sachet 36A of the medicine wrapping paper 20 located therebelow.

  After the medicine is stored in the sachet 36A of the medicine-wrapping paper 20 in this way, the control device pulls the medicine-wrapping paper 20 with the pull-in roller 30, and seals by heat-sealing heat welding as described above by the heat seal mechanism 27.

  Here, a shutter (not shown) is attached to the lower end of the shroud 13 to enter the pouch 36A and expand the opening 20B. At this time, the temporary heater 28 of the heat seal mechanism 27 is attached to the medicine packaging paper 20. Since the heat welding is performed from the folding portion 20A side to approximately the middle of the opening portion 20B, and the upper portion is not thermally welded, the medicine packaging paper 20 is pulled in by the pulling roller 30 without raising the shutter 13 (see FIG. 9 arrow direction).

  When the movement of the medicine wrapper 20 is stopped, the medicine heater 20 is thermally welded again by the main heater 29, and the medicine is packaged in the packaging bag 36. At the same time, the small bag 36A from the turntable 10 via the switch 13 is used. Stored inside. By repeating this, a predetermined number of types of medicines based on prescription data are automatically packaged. In FIG. 10, the longitudinal welded portion 38 and the lateral welded portion 39 to be described later are thermally welded by the temporary heater 28 and the main heater 29, but actually both sides separated by a predetermined dimension from the perforation 37 portion. While the position is heat-welded, the parallel portion 29B of the main heater 29 is heat-welded with a laterally welded portion 39 (including a wavy or saw-tooth shaped portion) formed on the opening 20B side of the packing bag 36.

  Here, as shown in FIG. 11, the heat-welded portion of the medicine-wrapping paper 20 divides the packaging bag 36 at substantially equal intervals, and a vertical welding portion 38 that seals in a direction orthogonal to the longitudinal direction of the belt-shaped medicine-wrapping paper 20; The longitudinal welding portion 38 is generally continuous, and is composed of a lateral welding portion 39 that seals the mating surface of the band-shaped medicine-wrapping paper 20 in the same direction as the longitudinal direction. That is, the medicine wrapping paper 20 as described above is folded in half from the folding portion 20A, and the vertical welded portion 38 and the lateral welded portion 39 are welded by the palm-packing heat in the medicine packaging machine 1, and the vertical welded portion 38 is perforated by the sewing blade. 37 is formed. Thereby, each sachet 36 can be easily separated.

  In addition, when using the medicine-wrapping paper 20 in which the notch 44 is formed in a wavy shape or a saw-tooth shape, when the two folding portions 20A of the medicine-wrapping paper 20 are folded, both side edge portions 43, 43 of the wavy or saw-tooth shape are close to each other The notches 44 are configured to overlap with each other. Further, if both side edge portions 43, 43 of the medicine wrapper 20 are formed in a short wavy shape or a saw blade shape with a pitch width of about 0.5 mm to 2 mm, it is perfect when the folding portion 20A of the medicine wrapper 20 is folded in two. Even if it does not overlap, the horizontal welding part 39 can be heat-welded (refer FIG. 1 (B)). This is preferable because the cut 44 can be formed on the opening 20B side of the packaging bag 36.

  Ii) the PET sheet 40 side having innumerable fine scratches (not shown); iii) the PET sheet 40 having innumerable fine scratches formed on the entire surface thereof, and both side ends thereof Using the medicine wrapping paper 20 in which the edges 43, 43 are formed into a notch 44 that is cut into a wave shape or a saw blade shape, the dispensed medicine is continuously separated by the heat welding type automatic medicine packaging machine 1 as described above. It can also be wrapped.

  When these medicine wrapping papers 20 are used, countless scratches are formed on the entire surface of the PET sheet 40. Therefore, when the medicine-wrapping paper 20 is pulled from an arbitrary position of the lateral welding portion 39 in a direction perpendicular to the lateral welding portion 39, the packaging containing the medicine is contained. The bag 36 can be easily opened.

  Moreover, according to the sachet bag 36 of the present invention, the packaged medicine can be guided not along the heat welded part but along the unheated welded part (folded part 20A). Even if there is, it can be surely taken without leaving.

  In this way, the packaging bag 36 containing the medicine has the medicine wrapping paper 20 folded in two and the transverse welded portion 39 is welded with the palm packaging heat by the medicine packaging machine 1, but the transverse welded portion 39 (the wavy or saw-tooth shaped portion) 2), the medicine wrapper raw material melted at the end of the triangular cut 44 of the medicine wrapper 20 leaks out and adheres to the parallel part 29B of the main heater 29. is there. When the raw material leaked to the end of the triangular notch 44 adheres to the parallel portion 29B, the side edge 43 of the medicine wrapper 20 sticks to the parallel portion 29B and the medicine wrapper 20 cannot be retracted by the drawing roller 30. 1 has a problem.

  FIG. 12 shows a packaging bag 36 that can prevent the medicine-wrapping paper material melted at the end of the triangular cut 44 from leaking out. In this case, the medicine wrapping paper 20 is configured in the same belt shape as described above for making a plurality of sachets 36 which are separated while being taken and contain medicines therein. The raw material of the medicine wrapper 20 is also composed of the same transparent composite plastic sheet 42 as described above. Triangular notches 44 and 44 similar to the above-mentioned serrated blade shape are formed on both side edge portions 43 and 43 of the medicine-wrapping paper 20 (transparent composite plastic sheet 42).

  The notch 44 is formed in a triangular shape having a bottom 44A with the tip of the hypotenuse positioned in the direction of the folded portion 20A and a peak 44B with the tip of the hypotenuse positioned in the separating direction of the fold 20A. Then, in a state where the medicine wrapper 20 is folded in two from the folding portion 20A, the triangular cut 44 bottom 44A provided on one side of the medicine wrapper 20 and the triangular cut 44 bottom 44A provided on the other side overlap. It is configured (two-dot chain line in FIG. 13). In this case, it goes without saying that the triangular cut 44 crest 44B provided on one side of the medicine-wrapping paper 20 and the triangular cut 44 crest 44B provided on the other side overlap. That is, both side edge portions 43, 43 of the medicine wrapper 20 are configured such that when the medicine wrapper 20 is folded in two from the folding portion 20A, the triangular shapes (both incisions 44, 44) on both sides overlap each other. (FIG. 14).

  In addition, the cut 44 is formed so that the angle α of the bottom 44A, that is, the angle α formed by the opposite oblique sides of the triangular cut 44 is 110 degrees or less (in this case, between 110 degrees and 100 degrees), and the side edge The horizontal welded portion 39 provided in 43 is substantially in contact with the bottom 44A of the notch 44, and the both lateral welded portions 39 are welded together by heat (FIG. 15). Others are the same as described above. In addition, the thermal welding of the vertical welding portion 38 is not performed at the center portion of the perforation 37, and both end portions of the perforation 37 are thermally welded to a predetermined width (in this case, approximately the width dimension of the vertical welding portion 38), and adjacent packaging The vertical welding part 38 of the bag 36 is continuously heat-welded (FIG. 12).

  Thereby, when taking out the medicine stored in the packaging bag 36, the packaging bag 36 can be opened along the cut 44 of the medicine-wrapping paper 20 (transparent composite plastic sheet 42). Even if the packaging bag 36 is made of a transparent composite plastic sheet 42 that is difficult to cut in comparison with a packaging sheet such as polyethylene laminated cellophane paper or polyethylene laminated glassine paper, it can be easily cut from a notch 44 portion at a desired position. Is possible.

  In this case, since the portion where the cut 44 is formed is not thermally welded, it is possible to prevent the raw material of the medicine-wrapping paper melted at the end of the triangular cut 44 from leaking out. Thereby, it is possible to eliminate the occurrence of a problem in the packaging mechanism due to the raw material from which the bottom 44A of the triangular cut 44 leaks out, and the ease of opening and the appearance of the packaging bag being impaired.

  Further, when the medicine wrapping paper 20 is folded in two from the folding portion 20A, the notches 44 of the side edge portions 43, 43 are substantially matched to each other, so that the side edge portions 43, 43 of the packaging bag 36 are aligned with each other. The mosquitoes that are cut into the provided cut 44 portion (triangular bottom 44A) are easily concentrated. Further, when the force to be cut into the cut 44 portions of the side edge portions 43 and 43 is concentrated, it is possible to open the packaging bag 36 from the cut 44 portion even with a relatively weak force. Thereby, even for elderly people and children, especially sick people with weak hands, the medicine wrapper 20 (transparent composite plastic sheet 42) is cut into the side edge portions 43, 43 of the double-folded packaging bag 36. It can be easily cut from 44.

  In addition, since the angle α formed by the opposite hypotenuses of the triangular notch 44 is 110 degrees or less, even when the medicine wrapping paper 20 (transparent composite plastic sheet 42) is pulled during the medicine packaging process in the medicine packaging machine 1. The transparent composite plastic sheet 42 is difficult to tear, and the angle α of the notch 44 is too large when the packaging bag 36 is opened, so that, for example, the patient does not easily concentrate the force that opens the packaging bag 36. Thereby, the packaging bag 36 which can be used suitably for the packaging of the medicine in the medicine packaging machine 1 and can be easily opened by the patient can be provided.

  Next, FIG. 16 shows a sachet 36 according to still another embodiment of the present invention. In this case, the notch 44 of the packaging bag 36 and the lateral welded portion 39 are spaced apart by a predetermined size, and the lateral welded portion 39 is welded together. That is, the heat welding location (lateral welding portion 39) is spaced from the bottom 44A of the notch 44 by 0.5 mm to 1.0 mm (in the range of the arrow in FIG. 17). As a result, when the lateral welded portion 39 is subjected to the palm-welded heat welding, the leaked sealant is contained between the lateral welded portion 39 and the notch 44 and does not flow out to the end of the notch 44. It is possible to more effectively prevent the raw material of the medicine wrapping paper from leaking out, and to eliminate the loss of ease of opening by the raw material from which the bottom 44A of the triangular cut 44 is leaked. be able to.

  In particular, since the notch 44 of the packaging bag 36 and the lateral welding portion 39 are spaced apart from each other by a predetermined size, when the patient opens the packaging bag 36, the opening force is the bottom of the triangular notch 44 of the packaging bag 36. It becomes possible to concentrate on 44A, and the sachet 36 can be easily opened even by an elderly person or a child, especially a sick person with weak hand strength.

  Next, FIG. 18 shows another sachet 36 of the present invention. Also in this case, the notches 44 of the side edge portions 43, 43 of the medicine wrapper 20 are a bottom 44A where the tip of the hypotenuse is positioned in the direction of the folded portion 20A, and a peak portion 44B where the tip of the hypotenuse is located in the separating direction of the folded portion 20A. It is formed in a triangular shape consisting of Then, the triangular notch 44 bottom 44A provided on one side of the medicine wrapper 20 and the triangular notch 44 crest 44B provided on the other side overlap with each other in a state in which the medicine wrapper 20 is folded in two from the folding part 20A. (Two-dot chain line in FIG. 18). Also in this case, it goes without saying that the triangular cut 44 crest 44B provided on one side of the medicine-wrapping paper 20 and the triangular cut 44 bottom 44A provided on the other side overlap. That is, both side edge portions 43 and 43 of the medicine wrapper 20 are configured such that when the medicine wrapper 20 is folded in two from the folded portion 20A, the triangular shapes (both cuts 44 bottom 44A and peak 44B) on both sides are shifted from each other. (FIG. 19).

  Thereby, the opened end of the sachet 36, which is cut from the notch 44 portions provided on the side edge portions 43, 43 of the medicine wrapping paper 20, can be shifted. Moreover, it becomes possible to make it easy to open the sachet 36 that is shifted by opening the sachet 36. Therefore, the user can take out the medicine in the packing bag 36 very easily.

  Next, FIG. 20 shows another sachet 36 of the present invention. In this case, the triangular notch 44 bottom 44A and peak 44B of the side edge portions 43, 43 of the medicine wrapper 20 are formed in a curved shape. Specifically, the radius R of the triangular cut 44 bottom 44A of the side edge portions 43, 43 of the medicine-wrapping paper 20 is a curved shape of 2 μm to 10 μm (arrow in FIG. 21). In this case, the size of the curved shape of the bottom 44A of the triangular notch 44 is such that the medicine packaging paper 20 is difficult to tear even when the medicine packaging paper 20 is pulled during the medicine packaging process in the medicine packaging machine 1. When cutting 36 from the notch 44 portion, the patient can easily open the packing bag 36 in a curved shape. Further, the joint heat welding location (lateral welding portion 39) and the notch 44 bottom portion 44A are separated by a predetermined dimension (in this case, 0.5 mm to 1.0 mm apart as described above).

  Here, when the hypotenuse is continuously cut with a blade (not shown) on both side edge portions 43, 43 of the medicine wrapper 20 to provide a triangular cut 44, the tip of the hypotenuse is slightly forward of the bottom 44A (on the opposite side of the peak portion). If it is not cut in the direction), it cannot be cut into a triangle. That is, when the triangular cut 44 having no curved shape is continuously cut at the bottom 44A of the cut 44, an extended cut 44C extending beyond the bottom 44A is inevitably formed in the triangular bottom 44A ( FIG. 22).

  If the extended cut portion 44C is formed in the triangular bottom portion 44A, when the sachet 36 is opened, the sachet 36 is torn in the opposite direction and the medicine scatters from the sachet 36. Inconvenience may occur. Therefore, in the embodiment of FIGS. 20 and 21, a curved shape is provided on the bottom 44A of the triangular notch 44 of the side edge portions 43, 43 of the medicine-wrapping paper 20, and the sachet 36 is split in the opposite direction. The inconvenience that the medicine scatters from the inside of the sachet 36 is prevented.

  If the bottom 44A of the cut 44 of the medicine wrapper 20 has a predetermined curved shape with the above-mentioned dimensions, the medicine wrapper 20 is difficult to tear during the medicine packaging process in the medicine packaging machine 1, and the patient opens the packaging bag 36. In addition, since it is possible to concentrate the cutting force on the bottom 44A of the triangular cut 44 of the packaging bag 36, the packaging bag 36 can be easily opened along the direction of the cutting 44. By tearing in the direction opposite to the intention, it is possible to prevent inconvenience that the medicine scatters from the inside of the packaging bag 36. In the drawing, the triangular notch 44 peak 44B is also curved, but the notch 44 peak 44B may remain triangular.

  FIG. 23 shows another example of the packaging bag 36. In this case, the dividing bag 36 is provided with a plurality of cuts 45 at the end instead of the triangular cut 44. The cut 45 is provided with a cut 45 of about 0.5 mm to 1.0 mm from the opening 20B of the packaging bag 36 toward the folded portion 20A. Even if the cut 45 has a smaller size, the size is not limited to the above as long as the packaging bag 36 can be cut open from the cut 45 portion. In this way, since the sachet 36 is provided with a plurality of cuts 45 instead of the triangular cuts 44, even an elderly person or a child, particularly a sick person with weak hand strength, can easily separate. The bag 36 can be cut open.

In addition, although the solid formulation was demonstrated as a chemical | medical agent in the Example, this invention is effective even if it is a granule formulation and a powder formulation not only in the solid formulation which concerns.
