Description

  The present invention relates to a PTP sheet for packaging medicine.

  PTP (Press Through Package) packaging is widely used in the field of pharmaceutical packaging for packaging solid drugs such as tablets and capsules. PTP packaging is mainly performed by molding a pocket containing a medicine into a resin film, filling the pocket with the medicine, and then sealing the pocket with a sheet made of aluminum foil (hereinafter simply referred to as aluminum foil) ( Sheet).

  The removal of the medicine from the PTP sheet is performed according to the following procedure. When the patient presses the medicine with the fingertip through the pocket, the pocket is elastically deformed and the medicine is pressed against the aluminum foil. The aluminum foil is broken by the drug, and the drug is taken out of the pocket.

  When storing or transporting a drug, or when the drug is carried by a patient, a plurality of PTP sheets may be in a state of being overlapped with each other. At that time, the PTP sheets are often superimposed such that the surfaces on the side where the pockets protrude are close to each other. In such a state, since the pocket of the other PTP sheet enters the space between the pockets of the one PTP sheet, the thickness in a state where a plurality of PTP sheets are stacked can be reduced. At the same time, it is possible to prevent the pocket from being directly pressed by an external force. Hereinafter, this state is also referred to as a tying state. Patent Literature 1 discloses a PTP sheet that can be tied together.

Japanese Patent No. 5915134 Registered Utility Model No. 3173833

  In the tying state of the PTP sheet, the pocket is in contact with the opposing PTP sheet. Therefore, when the outer surfaces of the tied PTP sheet are pressed against each other, the pocket is pressed and deformed by the opposing PTP sheet, or the aluminum foil is broken by the agent pressed through the pocket. Sometimes. Alternatively, when the medicine is a capsule or the like, the capsule may be deformed by pressing.

  For example, when a patient carries a PTP sheet in which a medicine is sealed in a bag or the like and carries it around, both outer surfaces of the laminated body of the PTP sheet in a tied state are pressed by other articles, thereby causing Symptoms may occur.

  Further, in order to maintain the tying state, a rubber band or the like may be wound around the PTP sheet in the tying state. For example, when there is no pocket at the position where the rubber band is wound, such as when one pocket is included in one PTP sheet, the opposing PTP sheets approach or come into contact with each other by being pressed by the rubber band. It may be deformed as follows. As a result, the pocket also comes into contact with the facing PTP sheet, and the above-described phenomenon is likely to occur.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a PTP sheet that can protect a pocket from being pressed by an external force in a tied state.

  (1) The medicine-packing PTP sheet according to the present invention includes a first sheet having a rectangular outer shape, in which a pocket for accommodating a medicine is protruded on the first surface, which is one of the front and back surfaces, and the first sheet in the first sheet. A second sheet having a rectangular outer shape that is adhered to the second surface opposite to the one surface and closes the opening of the pocket. The first sheet to which the second sheet is adhered is curved such that both ends of a pair of opposing sides of the rectangle are located in a direction in which the pocket protrudes from the center.

  According to the above configuration, in the pair of drug packaging PTP sheets in the tied state, the center of each first sheet is curved in a direction away from each other, so that the space on the first surface side of the opposing first sheet is reduced. growing. This makes it difficult for the first surface of the first sheet to abut the opposing pocket. In addition, since the waist (rigidity) of the first sheet is increased by the curvature of the first sheet, even when an elastic annular band such as a rubber band is wound around the PTP sheet for medicine packaging in a tied state, the elastic annular band exerts a force. The first sheet is not easily deformed.

  (2) Preferably, the pocket is located at a center in the first direction along the pair of sides.

  According to the above configuration, in the tying state, the pocket is located at the position where the first surface of the opposing first sheet is farthest, that is, at the center in the first direction.

  (3) Preferably, the pocket is shifted in one direction with respect to a center in the second direction along another pair of sides intersecting the pair of sides.

  According to the above configuration, the pockets do not abut each other in the tied state.

  (4) Preferably, the first sheet has a writing area at a position including the center of the first surface in the first direction, where the writing area can be written with a writing instrument, and the writing area is in the second direction. Are located asymmetrically with respect to the center of the pocket.

  According to the above configuration, in the tying state, the pocket and the writing area do not abut.

  (5) Preferably, the first sheet has a convex portion protruding from the first surface in the same direction as the pocket, and the pocket and the convex portion are positioned with respect to a center in the first direction. And asymmetric position.

  According to the above configuration, in the tying state, the convex portion comes into contact with the first surface of the opposing first sheet, so that the load on the pocket is reduced.

  (6) Preferably, the pocket is located at the center in the first direction along the pair of sides, and the protrusions are located on both sides of the pocket in the first direction and overlap the pocket. Not in a position.

  According to the above configuration, in the space where the first surfaces in the tied state face each other, the convex portion and the first surface abut on both sides in the first direction where the first surfaces are relatively close to each other. Is difficult to abut on the opposing first surface.

  (7) Preferably, the pocket is shifted in one direction with respect to a center in a second direction along another pair of sides intersecting the pair of sides, and the convex portion is It is shifted to the other direction with respect to the center in two directions.

  According to the above configuration, in the space in which the first surfaces in the tied state face each other, the side facing one side with respect to the center in the second direction of one first sheet, and the second surface facing the convex portion on both sides of the pocket. One surface comes in contact. That is, at a position relatively close to the pocket, the convex portion and the first surface opposed to each other come into contact with each other.

  (8) Preferably, there is one pocket.

  (9) The present invention includes the pair of drug packaging PTP sheets, and the drug packaging PTP sheet has the first surfaces facing each other with the pair of sides facing each other, and In a state where the pockets do not abut each other, the pockets may be regarded as a pair of PTP sheets for medicine packaging integrated by an elastic annular band.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings as appropriate. The embodiment described below is merely an example of the present invention, and it goes without saying that the embodiment of the present invention can be appropriately changed without changing the gist of the present invention. In the following description, the up-down direction 5 is defined based on the up-down direction, the front-rear direction 6 is defined in a direction perpendicular to the up-down direction 5, and the left-right direction 7 is defined in a direction perpendicular to the up-down direction 5 and the front-rear direction 6, respectively. Is defined. Here, the left-right direction 7 is an example of the first direction of the present invention, and the front-rear direction 6 is an example of the second direction of the present invention.

[Schematic Configuration of PTP Sheet 10]
As shown in FIG. 1, the PTP sheet 10 is a rectangular sheet in plan view. In the outer shape of the PTP sheet 10, the corners of the rectangle may be rounded. Figure 4
As shown in (1), the PTP sheet 10 is implemented in a state where tablets and capsules (hereinafter, these are collectively referred to as a medicine 11) are sealed inside. In this embodiment, one medicine 11 is sealed in one PTP sheet 10.

  In plan view, the dimension of the PTP sheet 10 in the front-rear direction 6 is, for example, 6 to 12 cm, and in the present embodiment, an example of 10 cm is shown. The dimension in the left-right direction 7 is, for example, 3 to 7 cm. In the present embodiment, an example of 5.4 cm is shown.

  The PTP sheet 10 has a first sheet 14 molded of polypropylene and a second sheet 15 of an aluminum film adhered thereto. The medicine 11 is stored in a pocket 16 formed in the first sheet 14. The opening of the pocket 16 is closed by the second sheet 15. When the pocket 16 of the first sheet 14 is pressed by the fingertip of the patient, the pocket 16 is elastically deformed and presses the medicine 11 toward the second sheet 15. When the medicine 11 pushes through the second sheet 15, the medicine 11 is taken out of the pocket 16 through the opening.

  For example, in the case of storage or transportation, a plurality of PTP sheets 10 are stacked in the same posture with the pocket 16 of each PTP sheet 10 facing upward and the second sheet 15 facing downward and stored in a packaging box or the like. .

  On the other hand, when the PTP sheet 10 is delivered to the patient or carried by the patient, as shown in FIG. 6, the two PTP sheets 10 are overlapped so that the first sheets 14 face each other, and the It is said. The tying state is a state in which the two PTP sheets 10 are opposed to each other with the first sheets 14 facing each other, and the pockets 16 of the two PTP sheets 10 are located in the space between the first sheets 14.

  Hereinafter, each component of the PTP sheet 10 will be described in more detail. In the following description, the expressions “upper surface” and “lower surface” of each sheet may be used, but these are based on the orientation of the PTP sheet 10 in FIG. The upper surface of the first sheet 14 (the surface on which the pocket 16 is projected) corresponds to the first surface, and the lower surface (the surface on which the second sheet 15 is adhered) corresponds to the second surface.

[First sheet 14]
The first sheet 14 shown in FIG. 1 is a sheet formed by vacuum molding of polypropylene (PP) which is a thermoplastic resin. The first sheet 14 has a certain translucency. Thereby, the patient can see through the first sheet 14 and visually recognize characters and designs described on a second sheet 15 (see FIG. 3) described later.

  However, as long as the first sheet 14 has a light-transmitting property enough to allow characters and designs described on the second sheet 15 to be visually recognized and can be elastically deformed by pressing a fingertip, Other resins may be used. For example, the first sheet 14 may be made of polyvinyl chloride (PVC), polyethylene terephthalate (PET), or cyclic polyolefin. Alternatively, the first sheet 14 may be formed by coating a resin layer with a different thin film. Alternatively, the first sheet 14 may be configured by laminating two or more resin layers.

  As shown in FIG. 1, the first sheet 14 is provided with one pocket 16. As shown in FIG. 4, the pocket 16 is formed in a dome shape so that the first sheet 14 protrudes upward. That is, in the pocket 16, the upper surface of the first sheet 14 is protruded upward, and the lower surface is depressed upward. An internal space for accommodating the medicine 11 is formed in the depressed portion. An opening that connects the internal space and the external space is open to the lower surface of the first sheet 14. The dimensions of the pocket 16 are such that the medicine 11 can be completely accommodated, and are appropriately changed depending on the size of the medicine 11. In the present embodiment, the outer shape of the pocket 16 in plan view is an elliptical shape whose dimension in the left-right direction 7 is longer than that in the front-rear direction 6. Note that the pocket 16 is not limited to the dome shape, and may be, for example, a shape having a flat protruding end.

  As shown in FIG. 1, the first sheet 14 is provided with two convex portions 18. As shown in FIG. 5, the convex portion 18 is formed by molding the first sheet 14 into a dome shape, similarly to the pocket 16. On the other hand, the difference from the pocket 16 is that the medicine 11 is not stored in the internal space formed by the projection 18. The shape of the projection 18 is preferably different from the shape of the pocket 16 to facilitate identification. As shown in FIG. 1, in the present embodiment, the external shape of the projection 18 in a plan view is a regular hexagon. The convex portion 18 supports the PTP sheet 10 on the opposite side when the PTP sheet 10 is tied up. Details of the tying state will be described later.

  As shown in FIG. 1, a writing area 20 is formed on the first sheet 14. The writing area 20 is formed by, for example, laminating a coating film on which characters can be written with a pencil lead or ballpoint pen ink on the upper surface of the first sheet 14. Further, the writing area 20 may be translucent enough to be able to read the print of the second sheet 15 through the first sheet 14. In the entry area 20, the date, day of the week, etc., for taking the medicine 11, can be entered with a writing instrument. Note that the writing area 20 may be formed by laminating paper or the like on the first sheet 14, or may be formed by sandblasting or embossing the surface of the first sheet 14.

[Second sheet 15]
As shown in FIG. 3, the second sheet 15 is an aluminum film adhered to the lower surface (second surface) of the first sheet 14 in a state where the medicine 11 is stored in the pocket 16. In FIG. 3, the positions of the pockets 16, the protrusions 18, and the writing areas 20 formed on the first sheet 14 are indicated by broken lines. As shown in FIG. 4, the opening of the pocket 16 is closed by the second sheet 15, and the medicine 11 is sealed inside the pocket 16. Further, as shown in FIG. 5, the opening of the protrusion 18 is closed by the second sheet 15.

  The thickness of the second sheet 15 is set such that when the patient presses the medicine 11 through the pocket 16, the second sheet 15 is broken by the pressing force from the medicine 11. In the present embodiment. The thickness of the second sheet 15 is 20 μm. However, the thickness of the second sheet 15 may be appropriately changed according to the hardness of the medicine 11, for example, whether the medicine 11 is a tablet or a capsule. Also, as long as the material of the second sheet 15 satisfies the above requirements, a material other than aluminum may be used. For example, the second sheet 15 may be a metal other than aluminum, or may be an alloy of aluminum and another metal. Further, another chemical material may be used for the second sheet 15 as long as the airtightness of the pocket 16 can be ensured.

  In a state where the medicine 11 is stored in the pocket 16, the first sheet 14 and the second sheet 15 are crimped in a heated state. At this time, the first sheet 14 and the second sheet 15 are welded by the solidification of the lower surface of the first sheet 14 that has been partially melted by heat.

  Although not shown in the figure, characters and designs that can be visually recognized by a pharmacist and a patient are described on the upper surface and the lower surface of the second sheet 15, respectively. The characters and designs written on the upper surface of the second sheet 15 are visible from the upper surface of the first sheet 14 through the first sheet 14.

[Curved shape of PTP sheet 10]
As shown in FIG. 2, the first sheet 14 to which the second sheet 15 is adhered, that is, the first sheet 14 and the second sheet 15 are arranged along the left-right direction 7 in the rectangular shape which is the outer shape in plan view. The two short ends 21E of the short side 21 are curved such that the pockets 16 project beyond the center 21C, that is, upward in the vertical direction 5. In other words, as shown in FIG. 2, the first sheet 14 and the second sheet 15 are curved so as to form a downwardly expanding arc when viewed along the front-rear direction 6.

  Although the degree to which the first sheet 14 and the second sheet 15 are curved is not limited, in this embodiment, both ends 21E of the short side 21 have a height at which the pocket 16 projects from the upper surface of the first sheet 14 in the up-down direction 5. It is at the same position as 1/2 of 16T. The first sheet 14 and the second sheet 15 are, for example, when the first sheet 14 and the second sheet 15 are pressed against each other in a heated state, the first sheet 14 is supported on the circumferential surface of the roller. Accordingly, the roller is curved along the circumferential surface of the roller.

[Arrangement of pocket 16, convex portion 18, and entry area 20]
As shown in FIG. 1, in the PTP sheet 10 in plan view, the pocket 16 is located at the same position as the center 21 </ b> C of the short side 21 in the left-right direction 7. In other words, the pocket 16 is located on the virtual straight line V1 that passes through the center 21C of the short side 21 and extends in the front-rear direction 6. The center of the pocket 16 in the left-right direction 7 does not necessarily have to be located on the virtual straight line V1.

  Further, the pocket 16 is located in the front-rear direction 6 so as to be shifted forward (one example of one direction) with respect to the center 22 </ b> C of the long side 22 of the first sheet 14 and the second sheet 15. In other words, the pocket 16 is located before the virtual straight line V2 passing through the center 22C of the long side 22 and extending in the left-right direction 7 in the front-rear direction 6. That is, the virtual straight line V2 does not pass through the pocket 16.

  The writing area 20 is located on the entire upper surface of the first sheet 14 in the left-right direction 7. The writing area 20 is located at a position asymmetrical to the pocket 16 with respect to the virtual straight line V2 in the front-back direction 6. In other words, the distance in the front-rear direction 6 between the front end and the rear end of the entry area 20 and the virtual straight line V2 is different from the distance in the front-rear direction 6 between the front end and the rear end of the pocket 16 and the virtual straight line V2.

  Further, the writing area 20 is located at a position asymmetrical to each projection 18 with respect to the virtual straight line V2 in the front-back direction 6. In other words, the distance in the front-rear direction 6 between the front end and the rear end of the entry area 20 and the virtual straight line V2 is different from the distance in the front-rear direction 6 between the front end and the rear end of each projection 18 and the virtual straight line V2.

  The pocket 16 and each of the projections 18 are located at positions that are asymmetric with respect to the virtual straight line V1 in the left-right direction 7. In the present embodiment, the pocket 16 is located at the center 21 </ b> C of the short side 21, and each projection 18 is located on both sides of the pocket 16 in the left-right direction 7 and at a position that does not overlap with the pocket 16. In the present embodiment, the protrusions 18 are at the same position in the front-rear direction 6 and at positions symmetrical with respect to the virtual straight line V1 in the left-right direction 7.

  In addition, each convex portion 18 is positioned to be shifted rearward (an example of the other direction) with respect to the center 22 </ b> C of the long side 22 in the front-rear direction 6. In other words, each projection 18 is located after the virtual straight line V2 in the front-back direction 6. That is, the virtual straight line V2 does not pass through each convex portion 18.

[Tying PTP sheet 10]
Hereinafter, the tying state of the PTP sheet 10 will be described with reference to FIGS. Although the two PTP sheets 10 in the tying state have the same configuration, the PTP sheet 10 located below in the tying state is referred to as a PTP sheet 10L, and the PTP sheet located above 10 is called a PTP sheet 10H. Further, the reference numerals indicating the members constituting each of the PTP sheets 10L and 10H are also described with L and H added.

  The two PTP sheets 10L, 10H are superimposed such that the first sheets 14L, 14H face each other. In the two PTP sheets 10L and 10H, the short sides 21L and 21H and the long sides 22L and 22H face each other, but the two PTP sheets 10L and 10H are opposite in front, rear, left and right. That is, in the tying state shown in FIG. 6, the short side 21L located rearward in the PTP sheet 10L and the short side 21H located frontward in the PTP sheet 10H appear in a state where they face each other. That is, the PTP sheet 10L and the PTP sheet 10H are turned over so that one of the front-back directions 6 is reversed. The PTP sheet 10H is placed on the PTP sheet 10L.

  As shown in FIG. 1, in each of the PTP sheets 10H and 10L, the pockets 16L and 16H and the convex portions 18L and 18H are positioned asymmetrically with respect to the virtual straight lines V1 and V2. Therefore, in the tying state, the opposing pockets 16L, 16H and the opposing convex portions 18L, 18H are in a positional relationship in which none of them contacts.

  7 and 8, each convex portion 18L is located on both outer sides in the left-right direction 7 with respect to the pocket 16H. Each of the protrusions 18H is located on both outer sides in the left-right direction 7 with respect to the pocket 16L. The projections 18L, 18H are in contact with the first sheets 14L, 14H of the opposed PTP sheets 10L, 10H, respectively.

  In the tying state, each of the PTP sheets 10L and 10H is curved so as to expand in the vertical direction 5. Thereby, the first sheets 14L and 14H define a space 30 where the center in the left-right direction 7 is farthest. In this embodiment, the height at which the pockets 16L, 16H protrude from the first sheets 14L, 14H in the up-down direction 5 is the same as the height at which the projections 18L, 18H protrude from the first sheets 14L, 14H in the up-down direction 5, respectively. However, in the space 30, the respective convex portions 18L, 18H are in contact with the first sheets 14L, 14H on both sides of the pockets 16L, 16H in the left-right direction 7, so that the pockets 16L, 16H It does not contact the opposing PTP sheets 10L, 10H.

  In addition, as shown in FIG. 1, in each of the PTP sheets 10L and 10H, the entry areas 20L and 20H are located at positions that are asymmetrical with the pockets 16L and 16H and the convex portions 18L and 18H with respect to the virtual straight line V2. Therefore, as shown in FIGS. 7 and 8, in the tying state, the writing areas 20L and 20H are not located at positions facing the pockets 16L and 16H and the respective convex portions 18L and 18H. Therefore, in the tying state, each convex portion 18L, 18H abuts on the first sheet 14L, 14H at a position different from the entry areas 20L, 20H.

  As shown in FIG. 6, an elastic annular band such as a rubber band 31 may be wound around the PTP sheets 10L and 10H in the tied state in order to maintain the tied state. Generally, the rubber band 31 and the like are wound around the center of the long sides 22L and 22H of the PTP sheets 10L and 10H, that is, near the virtual straight line V2. Since the pockets 16L, 16H and the respective convex portions 18L, 18H are not located on the virtual straight line V2, the elastic force of the rubber band 31 acts in a direction to bring the PTP sheets 10L, 10H in the tied state closer. At this time, the rigidity is enhanced by the curvature of each PTP sheet 10L, 10H, and the long sides 22L, 22H of each PTP sheet 10L, 10H are easily maintained in a straight line. That is, the vicinity of the virtual straight line V2 of each of the PTP sheets 10L and 10H is not easily deformed so as to approach each other. Even if the curvature of each of the PTP sheets 10L and 10H is slightly deformed by the elastic force of the rubber band 31, that is, even if the curvature of each of the short sides 21L and 21H is deformed to return to a linear shape, the pockets 16L and The 16H comes into contact with the opposing PTP sheets 10L and 10H, so that the curvature of the PTP sheets 10L and 10H is maintained.

[Operation and effect of the present embodiment]
According to the present embodiment, in the PTP sheets 10L and 10H in the tied state, the center of each of the first sheets 14L and 14H is curved in a direction away from each other, and thus is partitioned by the opposed first sheets 14L and 14H. The space 30 is wider than in the case where the space 30 is not curved. This makes it difficult for the first sheets 14L, 14H to abut the opposing pockets 16L, 16H. Thereby, in the PTP sheets 10L and 10H in the tied state, the pockets 16L and 16H can be protected from being pressed by an external force.

  In addition, since the first sheets 14L and 14H are curved, the stiffness (rigidity) of the first sheets 14L and 14H is increased. Therefore, even if the rubber bands 31 and the like are wound around the PTP sheets 10L and 10H in a tied state, the rubber bands 31 and the like are used. The first sheets 14L and 14H are unlikely to be deformed by the force of.

  Further, since the pockets 16L and 16H are located at the center of the first sheets 14L and 14H in the left-right direction 7, the pockets 16L and 16H are located at a position where the opposing first sheets 14L and 14H are farthest from each other in the tying state. Is located.

  Further, since the pockets 16L and 16H are located in the center in the front-rear direction 6, that is, shifted forward with respect to the virtual straight line V2, the pockets 16L and 16H do not abut each other in the tying state. Note that the pockets 16L and 16H may be shifted in any of the front and rear directions with respect to the virtual straight line V2.

  Since the entry areas 20L and 20H are located at the center of the front-rear direction 6, that is, at positions asymmetric with the pockets 16L and 16H with respect to the virtual straight line V2, the pockets 16L and 16H and the entry areas 20L and 20H are in a tying state. Do not abut.

  Further, since the pockets 16L, 16H and the projections 18L, 18H are located at the center in the left-right direction 7, that is, at an asymmetric position with respect to the virtual straight line V1, the first sheet in which the projections 18L, 18H face each other in the tying state. The pockets 16L, 16H do not abut on the opposing first sheets 14L, 14H, or the load on the pockets 16L, 16H is reduced.

  The pockets 16L, 16H are located at the center in the left-right direction 7, and the protrusions 18L, 18H are located on both sides of the pockets 16L, 16H in the left-right direction 7 and do not overlap with the pockets 16L, 16H. Therefore, in the space 30 in the tied state, the protrusions 18L, 18H and the first sheets 14L, 14H abut on both sides in the left-right direction 7 where the first sheets 14L, 14H are relatively close to each other, so that the pockets 16L, 16H Are unlikely to contact the first sheets 14L and 14H facing each other.

  Further, the pockets 16L and 16H are located at the center in the front-rear direction 6, that is, shifted forward with respect to the virtual straight line V2, and the projections 18L and 18H are located shifted backward with respect to the virtual straight line V2.
