Description

  The present invention relates to a press-through pack package (hereinafter abbreviated as PTP package) containing a solid medicine in a pocket portion of a sheet base material, and more particularly to a PTP package having an overall cylindrical structure.

  In general, a drug PTP package is a solid drug such as a round tablet or capsule in a large number of pockets provided on a rectangular transparent sheet substrate made of a thermoplastic resin such as polyvinyl chloride, polypropylene or polyethylene terephthalate. Are stored one by one, and a breakable lid film made of aluminum foil or the like is adhered to the back side of the sheet base material and sealed, and the pocket portion bulging on the front side is pushed with a fingertip. By crushing, the solid medicine in the pocket portion is released through the lid film.

  By the way, the initial drug PTP package can be separated into one pocket unit (one drug unit) by hand-folding at the vertical and horizontal dividing lines provided on the sheet base material, but the separated PTP package is broken. There were many accidents in which the entire body was taken without sealing, and gastrointestinal tracts such as the esophagus were injured at the corners of the sheet substrate, causing bleeding and causing serious complications. For this reason, recent drug PTP packages have a shape that can be separated only in two or three pocket units only by a horizontal dividing line so that it is difficult to accidentally swallow in size. However, even when the separation unit of the PTP package is increased in this way, the separated PTP package may be taken especially in the case of elderly people, and the separated PTP package for sorting into single dose medicines. There were many cases in which the body was further cut into pockets with a spear or the like and swallowed by a detour.

  Therefore, the present inventors have previously made a sheet fold 1 for the prevention of accidental ingestion, for example, from a sheet-like PTP package P0 as shown in FIG. As shown in FIG. 8, a PTP package P5 having a tubular shape with the lid film 2 as the inner surface side as shown in FIG. 8 is proposed by fastening the side edges 1a and 1b (Patent Documents 1 to 3). . In such a cylindrical form of the drug PTP package P5, it cannot be separated into 1 to 3 pocket units, and in order to take out the solid drug M, each pocket part 10 must be crushed with a finger as shown in the figure. Therefore, there is no concern that the user swallows the entire package without breaking it. In this case, since the medicine M is released into the cylinder by the tearing of the lid film 2, the medicine M is easily sealed with an empty palm by opening the cylindrical end with the opening on one end side facing downward. There is an advantage that the medicine M can be prevented from escaping, and for example, if the medicine M is received in a shallow container R as shown in FIG. 9, the medicine M can be more reliably prevented from escaping. In addition, when a plurality of types of medicines M contained in the PTP package P5 are taken simultaneously, they are received in the same container R in the same manner, and these medicines M can be taken in a batch, which is convenient. In addition, as this cylindrical form, not only a square cylinder but a polygon cylinder, a cylinder, an elliptic cylinder, etc. more than a triangular cylinder and a pentagonal cylinder are included.

  Below, 1st-4th embodiment of the chemical | medical agent PTP package which concerns on this invention is described concretely with reference to drawings. The drug PTP packages P1 to P4 of these embodiments all have a cylindrical structure, but a sheet P1 package P0 in the form of a sheet as shown in FIG. By fixing the both side edge portions 1a and 1b, a cylindrical structure with the pocket portion 10 of the sheet substrate 1 as the outer surface side and the lid film 2 as the inner surface side is obtained. In addition, the same code | symbol is attached | subjected to the common part including FIGS. 7-10.

  The drug PTP package P1 of the first embodiment shown in FIG. 1 has a cylindrical structure of a square cylinder having a plurality of (four in the figure) pocket portions 10 on each side surface, but one diagonal direction of the square cylinder The ridges 11 and 11 that face each other are folded back, and the ridges 12 and 12 that face each other in the diagonal direction are brazed in a non-bending manner, thereby forming a flat shape when not in use. The medicine PTP package P1 is attached with a band plate material 3 as a cylindrical holding means.

  The non-bent ridges 12 and 12 in the flat form of the PTP package P1 are bulged outward in a narrow width to make it easier to bend into a mountain fold when making a tubular form to be described later. Yes. A cut groove 13 along the ridge line direction is formed on one end side of the one non-bent ridge line portion 12.

  The band plate material 3 is made of paperboard or a hard synthetic resin molding, and is integrally formed with a hook portion 31 projecting side by side in the form of an ear piece on one end side of the band plate portion 30 having a substantially constant width. Between the stop 31 and the strip plate portion 30, there is a cut groove 32 continuous from the side edge of the strip plate portion 30.

  In the medicine PTP package P1 of the first embodiment, when taking out the medicine M in each pocket 10 and taking it, the ridges 11 and 11 are first sandwiched from the flat form shown in FIG. Thus, the inner side is expanded so that the ridge line parts 12 and 12 are bent in a mountain fold to form a cylindrical shape. Then, as shown in FIGS. 2 (a) and 2 (b), from the one end side having the cut groove 13 of the PTP package P1 having a cylindrical shape, the band plate portion 30 of the band plate material 3 is folded in the plate surface direction. It inserts along the diagonal direction between the ridgeline parts 12 and 12 which became, and the cut groove | channel 32 is fitted in the cut groove | channel 13 of PTP package P1 in the form which takes out the latching | locking part 31 out of a cylinder. As a result, the PTP package P1 having a cylindrical shape has an isosceles triangular cross-sectional shape in which both sides of the band plate portion 30 of the inserted band plate material 3 have the band plate portion 30 as a base. As a stable cylindrical shape. Therefore, when the pocket portion 10 is crushed with a finger from the outside for taking out the medicine, the cylindrical shape of the PTP package P1 is not deformed, so that the lid film 2 can be easily opened and the medicine can be taken out easily. .

  The hooking portions 31 of the band plate material 3 may be provided on both the left and right sides as shown in the phantom line in addition to being provided only on the left and right sides of the band plate portion 30 as shown in the figure. In addition, including the case where the latching portions 31 are on both the left and right sides, one side of the cut groove 32 on the band plate material 3 side and the cut groove 13 on the PTP package P1 side may be omitted. Further, the width of the band plate portion 30 of the band plate material 3 is such that the space in the cylinder becomes narrow so that the release and drop of the medicine into the cylinder is not disturbed, as shown in FIG. It is desirable to set the upper limit of the width at which the cross-sectional shapes on both sides are right-angled isosceles triangles and the lower limit of the width at which the cross-sectional shapes are equilateral triangles. Further, such a band plate material 3 may be inserted inside the flat medicine PTP package P1 when not in use.

  Similarly to the drug PTP package P1 of the first embodiment, the drug PTP package P2 of the second embodiment shown in FIG. 4) a rectangular structure having a pocket 10 having a pocket 10, and the ridges 11, 11 facing each other in the diagonal direction of the square tube are folded back, and the ridges 12, 12, facing each other in the diagonal direction, By brazing each 12 in a non-bent form, it is in a flat form in an unused state. Moreover, the non-bending ridgeline parts 12 and 12 in this flat form bulge outwardly in a bowl shape with a narrow width like the first embodiment.

  A substantially square folding piece 4 as a cylindrical holding means is cut and formed on one side surface of the square cylinder of the PTP package P2. This folding piece 4 has a size that reaches the folded ridge line portion 11 with the tip thereof reaching the folded ridge line portion 11 with the non-bent ridge line portion 12 in the flat form as a base, and has a flat plate shape without the pocket portion 10 as a whole.

  In the medicine PTP package P2 of the second embodiment, when taking out the medicine M in each pocket 10 and taking it, the ridges 11 and 11 are first sandwiched from the flat form as in the first embodiment. Thereby, it is set as a cylindrical form by the inner side expansion which the ridgeline parts 12 and 12 become mountain folds. And as shown in FIG.3 (b), the folding piece 4 of this PTP package P2 made into the cylindrical form is folded inward. As a result, the PTP package P2 has a substantially rhomboid cross section as shown in the figure, and both sides of the folding piece 4 along the shorter diagonal direction are substantially equilateral triangles with the folding piece 4 as one side. It has a cross-sectional shape and is thus maintained in a firm and stable cylindrical form. Therefore, when the pocket portion 10 is crushed with a finger from the outside for taking out the medicine, the cylindrical shape of the PTP package P2 is not deformed, and the lid film 2 can be easily broken to take out the medicine easily. .

  The drug PTP package P3 of the third embodiment shown in FIG. 4 (a) has a plurality of (four in the figure) on each side surface, similar to the drug PTP packages P1, P2 of the first and second embodiments. A rectangular tubular structure having a pocket portion 10 is formed, and the ridge line portions 11 and 11 opposed in one diagonal direction of the square tube are folded, and the ridge line portions 12 and 12 opposed in the other diagonal direction are not bent. By being brazed to each other, it is in a flat form in an unused state. Moreover, the non-bending ridgeline parts 12 and 12 in this flat form bulge outwardly in a bowl shape with a narrow width, as in the first and second embodiments.

  A lid-like flap 5 serving as a cylindrical holding means is extended from one side of the square cylinder on one end side of the PTP package P3. The lid-like flap 5 is composed of a square base 51 corresponding to the opening of the square cylinder and an insertion piece 52 extending from the front edge thereof.

  In the medicine PTP package P3 of the third embodiment, when taking out the medicine M in each pocket portion 10 and taking it, first from the flat form, the ridge portions 11, 11 are taken, as in the first and second embodiments. And the ridgeline portions 12 and 12 are formed in a cylindrical shape by expanding inside the mountain fold. Then, as shown in FIG. 4 (b), the PTP packaging body P3 having a cylindrical shape is covered with a lid-like flap 5 on the opening on one end side thereof, and the insertion piece 52 is inserted inward to thereby form the PTP packaging. The body P3 is stably maintained in the form of a square cylinder having a square cross section. Therefore, when the pocket portion 10 is crushed with a finger from the outside for taking out the medicine, the cylindrical shape of the PTP package P3 is not deformed, and the lid film 2 can be easily opened to take out the medicine easily. .

  The drug PTP package P4 of the fourth embodiment has a cylindrical structure like the drug PTP packages P1 to P3 of the first to third embodiments, and in FIG. 5 (a) in an unused state. As shown in the figure, it is brazed in a flat form, and both sides in the width direction are folded back as ridge line parts 11, but a plurality of pairs of left and right pocket parts 10 are arranged at predetermined intervals in the longitudinal direction on both side surfaces in the flat form. There is no site | part corresponded to the ridgeline part 12 in 1st-3rd embodiment only by arrange | positioning. In addition, the flat groove is provided with a notch groove 13 similar to that of the first embodiment at the central position in the width direction on one end side, and a band plate member 3 is attached as the cylindrical holding means as in the first embodiment. In addition, this strip | belt board material 3 has the latching | locking part 31 projected on the both right and left sides of the one end side of the strip | belt board part 30, as shown in FIG.5 (b).

  In the medicine PTP package P4 of the fourth embodiment, when taking out the medicine M in each pocket 10 and taking it, the ridges 11 and 11 are first sandwiched from a flat form to approach each other as shown in FIG. As shown in b), both sides are curved outward so that the inside is expanded to form a substantially cylindrical shape. And as shown in FIG.5 (b), the plate | board surface direction of the strip | belt-plate part 3 of the strip | belt-plate material 3 is orthogonal to the flat direction in a flat form from the one end side of this PTP package body P4 made into this cylindrical form. The cut groove 32 (see FIG. 1) is fitted into the cut groove 13 of the PTP package P4 in such a manner that the latching portions 31 on both sides thereof are taken out of the cylinder. As a result, the PTP package P4 having a cylindrical shape has a substantially triangular cross-sectional shape in which both sides of the band plate portion 30 of the inserted band plate material 3 have the band plate portion 30 as the bottom and the ridge line portion 11 as the top. Therefore, it is kept in a solid and stable cylindrical form. Accordingly, when the pocket portion 10 is crushed with a finger from the outside for taking out the medicine, the cylindrical shape of the PTP package P4 is not deformed, and the lid film 2 can be easily broken to take out the medicine easily. .

  In addition, the brazing which makes the medicine PTP packaging bodies P1 to P4 flat is in the vicinity of the ridge lines 11 and 12 (only the ridge line 11 in the PTP packaging body P4 of the fourth embodiment) of the sheet base material 1 made of thermoplastic resin. However, it may be made into a flat shape by a secondary processing heat press, or it may be bent from the sheet-form medicine PTP package P0 and heated. You may make it a flat form. At the time of the latter's heating press, it is also possible to heat-seal both side edges 1a and 1b of the sheet-form medicine PTP package P0 to be fastened simultaneously.

  As illustrated in the first to fourth embodiments, the drug PTP package of the present invention has a tubular structure as a whole with the pocket portion 10 of the sheet substrate 1 as the outer surface and the lid film 2 as the inner surface. However, in the unused form, the cylindrical shape is brazed to a flat shape, which is not bulky, and it can be transported and stored without the need for space by stacking a large number of them. Further, when packaging as a drug product, for example, as shown in FIG. 6, it can be accommodated in a form in which a large number of flat drug PTP packages P1 to P4 are stacked on a case C such as a paper box. There is an advantage that the amount of medicine to be stored can be remarkably increased as compared with the case of storing in a form. In addition, in the package form of FIG. 6, the medicine PTP packaging bodies P1 to P4 are accommodated so as to reduce the excess space as much as possible by arranging them in opposition so that the positions of the pocket portions 10 are shifted from each other.

  On the other hand, when taking out and taking the medicine M in each pocket portion 10, as described above, the inside is expanded from the flat form to form a tubular form, and this tubular form is stabilized by the tubular holding means. Since it can keep, by the operation which crushes the pocket part 10 with a finger | toe, the lid | cover film 2 can be opened very easily and the chemical | medical agent M can be discharge | released in a cylinder. Therefore, the original accidental ingestion prevention function and dissipation prevention function as a cylindrical medicine PTP package are not impaired at all.

  In addition, in the embodiment, a regular square tube shape and a substantially cylindrical shape are exemplified as the cylindrical structure, but the cross-sectional rectangle can be formed into a parallel quadrilateral shape so as to be flat, or the side width can be brazed into a flat shape. As long as it is a combination of the above, a polygonal cylinder having a pentagonal cylinder or more can be adopted. Also, as the cylindrical holding means, various configurations other than the illustrated band plate material 3, the folding piece 4, and the lid-like flap 5 can be adopted.
