  By the way, when a drug taker or a drug provider transports a packaged body in which the drug is sealed, it is often transported in a state of a continuous package before the packaged body is divided. In this case, the continuous sachet has cut portions formed at positions corresponding to the respective sachets in the side edge portion extending in the longitudinal direction. Therefore, there is a possibility that the package is inadvertently released from the cut portion. Since the continuous sachet is in the form of a long band, a large tearing force acts on the incision when the part farther away from the incision is gripped, and the sachet opens carelessly. The risk of being increased.

  Further, in the package manufactured by the conventional drug package manufacturing apparatus, the continuous package is cut into one package, and then the drug user opens the package. When trying to do so, since there is only one opening for cutting, there is a possibility that a person with reduced vision cannot find it. In addition, when there is only one opening for cutting and one of them is broken for some reason, it is difficult for an elderly person or a person with weak muscle strength to tear and open the package. .

  Furthermore, the above-mentioned conventional medicine package manufacturing apparatus is provided with a separate blade for forming a notch at the side edge in the longitudinal direction of the continuous package, or with a special heat welding device. There is a problem that the apparatus is complicated.

A blade for manufacturing a medicine package, wherein each of the blades has a square pyramid shape with the tip as an apex, and from the tip of the blade to both sides of the plurality of blades in the row direction A pair of cutting blade edges that divide between adjacent drug packaging bodies and a tip of the blade portion in a direction orthogonal to the row direction. A ridge line extending toward the rear end side of the blade part is formed on both sides, and a pair of opening blade edges for opening each medicine package is provided.

  Further, in the blade part for producing a medicine package of the present invention, the two ridge lines that are the cutting edge are at an angle of 33 degrees or more and 37 degrees or less, and the two ridge lines that are the opening blade edge are The angle is 37 degrees or more and 41 degrees or less, and the distance between the tips of the adjacent blade portions is 1.5 mm or more and 2.0 mm or less.

  Moreover, the medicine package manufacturing apparatus of the present invention includes any one of the above-described blades for manufacturing a medicine package.

  In the medicine package of the present invention, a plurality of cut portions constituting a perforation for dividing are arranged in a region between adjacent packaging regions. Each of the incision parts is for cutting to extend in a direction perpendicular to the arrangement direction of the notches, continuous to the incision part for separation extending in the arrangement direction of the incisions, and the incision part for division. And a notch.

  Therefore, when the drug taker divides the drug package along the perforation line and divides it into individual packages, each package is opened for opening on its side edge. It can be opened using the notch part. Therefore, it is not necessary to separately form a notch for opening at the side edge in the longitudinal direction of the medicine package. That is, there is no problem that the package is inadvertently opened by the cut portions formed in the side edges in the longitudinal direction.

  Further, in the present embodiment, as shown in FIGS. 4 and 5A, the ridge 35 a functioning as each opening blade edge has one end that forms the tip of each blade 32, and the base 31 from the other end. An example is shown in which a surface sandwiched between two ridge lines 36 a and 36 b extending in the direction of the base 31 and the base 31 is formed in the same plane. However, the other end side of the opening blade edge may be configured with a shape different from this example.

  FIG. 5B is a top view of the blade body 30 viewed from the apex 40 side. It is desirable that the four ridge lines 34a, 34b, 35a, and 35b constituting each blade portion 32 have the same length.

  Next, the operation of the medicine package manufacturing apparatus will be described with reference to FIG. The package sheet S is pulled out from the roll body R set on the roll body support shaft 11 by the sheet conveying device 10. The drawn wrapping sheet S passes between the stamp unit 21 and the stamp receiving unit 22 of the stamp device 20 via the support shafts 12, 13, and 14 and is pulled out by the driving roller 15.

  The overlapped wrapping sheet S is spread before the drug hopper 3 by the sheet opening member 16 so as to have a width sufficient for the lower part of the drug hopper 3 to be inserted. When the medicine P divided by a certain amount is dropped from the medicine supply device 2, the medicine P passes through the funnel portion of the medicine hopper 3 and is received between the overlapped wrapping sheets S.

  The medicine P is accommodated in a bag portion formed by a seal region 111 welded in advance by the stamp portion 21 of the stamp device 20. After completion of the accommodation, the packaging sheet S is conveyed by a certain distance by the driving roller 15 and is welded again by the stamp unit 21. As a result, a packaging body region 112 including a packaging region 110 in which the medicine P is sealed and a sealing region 111 surrounding the packaging region 110 is sequentially formed at intervals.

  At the time of welding by the stamp unit 20, a cutting perforation 101 as shown in FIG. 6A is formed by the medicine package manufacturing blade 30 provided in the stamp unit 20. The blade 30 for manufacturing a medicine package is disposed between the first pressing portion 23a and the second pressing portion 23b. Therefore, the dividing perforation 101 is formed in a region (connection region) 113 between adjacent wrapping body regions 112. A part or all of the dividing perforations 101 may be formed in the seal region 111.

  FIG. 6B is an enlarged view of the individual cut portions 102 of the dividing perforation 101. As shown in FIG. 6 (b), the notch 102 includes a cutting notch 103 extending in the direction in which the notches 102 are arranged, and a cutting notch 103 that is continuous with the notch 103 for cutting. It forms a cross shape in which the opening cut-out portions 104 extending in a direction orthogonal to the arrangement direction are orthogonal to each other. Hereinafter, the cut portion 102 is referred to as a cross-shaped cut portion 102.

  The dividing notch 103 extends from the center of the cruciform notch 102 to one side in the row direction (vertical direction) of the cruciform notch 102 and to the other side. It consists of a longitudinal cut 103b that extends. The opening notch 104 is the same as the horizontal notch 104a extending from the center of the cross-shaped notch 102 to one side in the direction (lateral direction) orthogonal to the direction in which the cross-shaped notches 102 are arranged. It consists of a horizontal cut 104b extending to the other side.

  Further, a linear dividing start portion 109 is formed at the lower end portion of the dividing perforation 101 by the auxiliary blade portion 39. The dividing start part 109 is formed following the dividing perforation 101 and reaches the lower end of the medicine package 100. The dividing notch 103 that forms the notch 102 opposite to the dividing start portion 109 of the dividing perforation 101 does not reach the upper end of the medicine package 100.

  Next, a process in which the shape of the cut line 102 as described above is formed when the blade 30 for manufacturing a medicine package is pushed into the package sheet S will be described. When the distal end portion of the blade part 32 is pressed against the packaging sheet S, the cutting of the packaging sheet S is started by the pair of cutting blade edges and the pair of opening blade edges.

  Among these, the ridge lines 34a and 34b functioning as the cutting blade edges form vertical cut portions 103a and 103b along the row direction D of the blade portions 32, respectively. On the other hand, the ridge lines 35a and 35b that function as the cutting blade edges form horizontal cut portions 104a and 104b that extend in a direction perpendicular to the arrangement direction D of the blade portions 32 on the medicine package. Since the cutting notch 103 made of the vertical notches 103a and 103b and the opening notch 104 made of the horizontal notches 104a and 104b are orthogonal to each other, a cross-shaped notch Part 102 is formed.

  When the person who takes the medicine P opens the medicine package 100, first, the both sides of the dividing start portion 109 are pinched and spread in different directions. As a result, a tearing force acts on the tip of the dividing start portion 109, and the dividing start portion 109 is extended to the adjacent cross-shaped cut portion 102. The dividing start part 109 and the adjacent cruciform cut part 102 are connected to each other, and the dividing cut part 103 forming the cruciform cut part 102 is divided in such a manner that the both sides are widened away from each other. These divisions are continuously performed toward the upper end side of the drug package, whereby the drug package 100 is divided.

  The side edge portion 114 of the medicine package 100 formed by being cut along the cutting perforation 101 has a form as shown in FIG. The side edge portion 114 of the medicine package 100 is in a state in which the cutting portions 103 for cutting forming the adjacent cross-shaped cutting portions 102 are continuous with each other. The side edge portion 114 includes one of a pair of horizontal cut portions 104 a and 104 b that constitute the opening cut portion 104. The horizontal cuts 104a and 104b each extend in a direction perpendicular to the side edge 114.

  When taking the medicine P, the person taking the medicine pulls both sides of the side edge portion 114 away from each other, and concentrates the force on the distal end portions of the lateral cut portions 104a and 104b, whereby the medicine package 100 Can be opened.

  As described above in detail, the medicine package 100 shown in the present embodiment has a plurality of cross-like shapes constituting the perforation 101 for cutting in the connection region 113 sandwiched between the adjacent package regions 112. A notch 102 is provided. Each cross-shaped cut portion 102 includes a dividing cut portion 103 extending in the row direction, and an opening cut portion 104 extending in a direction perpendicular to the row direction.

  When the person taking the medicine P divides the medicine package 100 along the perforation line 101 for cutting, short transverse cuts 104a and 104b are formed on both sides of the divided side edges, and the person taking the medicine Can open the medicine package 100 more easily by using the horizontal cut portions 104a and 104b.

  Since the split start part 109 is always formed at the lower end of the split perforation 101, the user can tear the split start part 109 to ensure the continuous medicine package 100. It is possible to form individual independent packages.
