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

PTP (Press Through Package) packaging is widely used for packaging solid drugs such as tablets and capsules in the field of pharmaceutical packaging. PTP packaging is mainly a package ( sheet).

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

When storing or transporting a drug, or when a patient carries the drug, a plurality of PTP sheets may be placed on top of each other. At that time, the PTP sheets are often overlapped so that the surfaces on which the pockets protrude are close to each other. In such a state, the pocket of one PTP sheet enters the space between the pockets of the other PTP sheet, so that the thickness of the stacked PTP sheets 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 the tying state. Patent Literature 1 discloses a PTP sheet that can be tied together.

Japanese Patent No. 5915134 Registered Utility Model No. 3173833

When the PTP sheets are tied together, the pockets are in contact with the opposing PTP sheets. Therefore, when the outer surfaces of the PTP sheets that are tied together are pressed against each other, the pocket is deformed by being pressed by the opposing PTP sheets, or the aluminum foil is torn by the medicine pressed through the pocket. I can put it away. Alternatively, if the drug is a capsule or the like, the capsule may be deformed by pressing.

For example, when a patient carries a drug-sealed PTP sheet in a bag or the like, the outer surfaces of the stacked PTP sheet stack are pressed by other articles, thereby causing the above-mentioned problems. phenomena may occur.

Also, in order to maintain the tied state, the PTP sheets in the tied state may be wrapped with a rubber band or the like. For example, when there is only one pocket on one PTP sheet, if there is no pocket at the position where the rubber band is wound, the opposing PTP sheets will approach or contact each other by being pressed by the rubber band. There is a risk of deformation. As a result, the pocket also comes into contact with the facing PTP sheet, and the phenomenon described above is likely to occur.

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

(1) The PTP sheet for drug packaging according to the present invention comprises: a first sheet having a rectangular outer shape with a first surface protruding from one of the front and back surfaces of which is a pocket for accommodating a drug; a second sheet having a rectangular outer shape and attached to a second surface opposite to the first surface and closing the opening of the pocket. The first sheet to which the second sheet is attached is curved such that both ends of a pair of opposing sides of the rectangle are positioned in a direction in which the pocket protrudes from the center.

According to the above configuration, in the pair of medicine packaging PTP sheets that are tied together, the centers of the respective first sheets are curved in directions away from each other. growing. This makes it difficult for the first surface of the first sheet and the facing pocket to come into contact with each other. In addition, since the curvature of the first sheet increases the stiffness (rigidity) of the first sheet, even if an elastic annular belt such as a rubber band is wound around the PTP sheet for drug packaging in a tied state, the force of the elastic annular belt will The first sheet is difficult to deform.

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

According to the above configuration, in the tying state, the pocket is positioned at the position where the first surfaces of the facing first sheets are farthest apart, that is, at the center in the first direction.

(3) Preferably, the pocket is offset in one direction from the center in the second direction along another pair of sides intersecting the pair of sides.

According to the above configuration, the pockets do not come into contact with each other in the tied-up state.

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

According to the above configuration, the pocket and the writing area do not come into contact with each other in the tied-up state.

(5) Preferably, the first sheet has a protrusion projecting from the first surface in the same direction as the pocket, and the pocket and the protrusion are arranged with respect to the center in the first direction. are in asymmetrical positions.

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

(6) Preferably, the pocket is positioned at the center in the first direction along the pair of sides, and the projections overlap the pocket on both sides of the pocket in the first direction. in a position not to

According to the above configuration, in the space where the first surfaces face each other in the tying state, 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. It is difficult for the pocket located in the center to abut against the facing first surface.

(7) Preferably, the pocket is offset in one direction with respect to the center in the second direction along the other pair of sides intersecting the pair of sides, and the protrusion is located in the second direction. It is positioned shifted in the other direction with respect to the center of the two directions.

According to the above configuration, in the space where the first surfaces in the tying state face each other, the first sheets facing the convex portions on both sides of the pocket on the side facing one direction with respect to the center of the first sheet in the second direction. 1 surface abuts. That is, at a position relatively close to the pocket, the convex portion abuts against the opposing first surface.

Hereinafter, embodiments of the present invention will be described with reference to the drawings as appropriate. It should be noted that 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 changed as appropriate without changing the gist of the present invention. In the following description, a vertical direction 5 is defined based on the vertical direction, a front-rear direction 6 is defined as a direction perpendicular to the vertical direction 5, and a left-right direction 7 is defined as a direction perpendicular to the vertical direction 5 and the front-rear direction 6, respectively. defined. Here, the left-right direction 7 is an example of the first direction of the invention, and the front-rear direction 6 is an example of the second direction of the invention.

[Schematic configuration of PTP sheet 10]
As shown in FIG. 1, the PTP sheet 10 is a rectangular sheet in plan view. In addition, in the outer shape of the PTP sheet 10, the rectangular corners may be rounded. Figure 4
2, the PTP sheet 10 is implemented in a state in which a tablet or capsule (hereinafter collectively referred to as a drug 11) is sealed inside. In this embodiment, one drug 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 this embodiment, an example of 10 cm is shown. Also, the dimension in the left-right direction 7 is, for example, 3 to 7 cm, and in this embodiment, an example of 5.4 cm is shown.

The PTP sheet 10 is obtained by bonding a first sheet 14 made of polypropylene and a second sheet 15 made of an aluminum film. Medicine 11 is accommodated in pocket 16 formed in 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 patient's fingertip, the pocket 16 is elastically deformed and presses the drug 11 toward the second sheet 15 side. As the medicine 11 breaks the second sheet 15, the medicine 11 is taken out from the pocket 16 through the opening.

For example, when storing or transporting the PTP sheets 10, 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 handed over to the patient or carried by the patient, as shown in FIG. It is said that The tying state is a state in which the first sheets 14 of the two PTP sheets 10 face each other and the pockets 16 of the two PTP sheets 10 are positioned in the space between the first sheets 14 .

Each constituent member of the PTP sheet 10 will be described in more detail below. In the following description, expressions such as the upper surface and the lower surface of each sheet may be used, but these are based on the orientation of the PTP sheet 10 in FIG. Also, the upper surface of the first sheet 14 (the surface on which the pocket 16 protrudes) corresponds to the first surface, and the lower surface (the surface to which the second sheet 15 is attached) corresponds to the second surface.

[First sheet 14]
The first sheet 14 shown in FIG. 1 is a sheet vacuum-formed from 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 see characters and patterns written on the second sheet 15 (see FIG. 3), which will be described later.

However, if the first sheet 14 has translucency to the extent that characters and patterns written on the second sheet 15 can be visually recognized and can be elastically deformed by pressing with a fingertip, Other resins may be used. For example, polyvinyl chloride (PVC), polyethylene terephthalate (PET), or cyclic polyolefin may be used for the first sheet 14 . Alternatively, the first sheet 14 may be configured 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 shaped like a dome so that the first sheet 14 protrudes upward. That is, in the pocket 16, the upper surface of the first sheet 14 protrudes upward and the lower surface is depressed upward. An internal space in which the drug 11 is accommodated is formed in this recessed portion. An opening connecting the internal space and the external space is provided on the lower surface of the first sheet 14 . The size of the pocket 16 can completely accommodate the drug 11 and is appropriately changed according to the size of the drug 11 . In the present embodiment, the outer shape of the pocket 16 in a plan view is an ellipse in which the dimension in the left-right direction 7 is longer than the dimension in the front-rear direction 6 . Note that the pocket 16 is not limited to a dome shape, and may have, for example, a shape with a flat projecting end.

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

As shown in FIG. 1, the first sheet 14 has a writing area 20 formed therein. The writing area 20 is formed, for example, by laminating a coating film on the upper surface of the first sheet 14 in which characters can be written with pencil lead, ballpoint pen ink, or the like. Also, the writing area 20 may be semi-transparent to the extent that the print on the second sheet 15 can be read through the first sheet 14 . In the entry area 20, the month and day of taking the drug 11, the day of the week, etc. 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 with the drug 11 stored in the pocket 16 . In FIG. 3, the positions of the pocket 16, the projection 18, and the writing area 20 formed on the first sheet 14 are indicated by dashed lines. As shown in FIG. 4 , the second sheet 15 closes the opening of the pocket 16 and seals the drug 11 inside the pocket 16 . Further, as shown in FIG. 5 , the second sheet 15 closes the opening of the projection 18 .

The thickness of the second sheet 15 is such that when the patient presses the medicine 11 through the pocket 16 , the second sheet 15 is torn by the pressing force from the medicine 11 . In this 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 drug 11, for example, whether the drug 11 is a tablet or a capsule. Also, a material other than aluminum may be used for the second sheet 15 as long as it satisfies the above requirements. For example, the second sheet 15 may be a metal other than aluminum, or an alloy of aluminum and other metals. Also, other chemical materials may be used for the second sheet 15 as long as they can ensure the airtightness of the pocket 16 .

With medicine 11 stored in pocket 16, first sheet 14 and second sheet 15 are pressed together in a heated state. At that time, the first sheet 14 and the second sheet 15 are welded by solidifying the lower surface of the semi-melted first sheet 14 by the heat.

Although not shown in the drawings, characters and patterns visible to the pharmacist and the patient are printed on the upper and lower surfaces of the second sheet 15, respectively. Characters and patterns 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 outer shape in plan view. Both ends 21E of the short side 21 extending from the center 21C are curved so as to be positioned upward in the vertical direction 5 in the direction in which the pocket 16 protrudes from the center 21C. In other words, as shown in FIG. 2 , the first seat 14 and the second seat 15 are curved in an arcuate shape that expands downward when viewed along the front-rear direction 6 .

Although the extent to which the first sheet 14 and the second sheet 15 are curved is not limited, in the present embodiment, both ends 21E of the short side 21 are at a height at which the pocket 16 protrudes from the upper surface of the first sheet 14 in the vertical direction 5. It is at the same position as 1/2 of 16T. 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. is curved along the circumferential surface of the roller.

[Arrangement of Pocket 16, Projection 18, and Writing Area 20]
As shown in FIG. 1, in the plan view of the PTP sheet 10, the pocket 16 is located at the same position as the center 21C of the short side 21 in the left-right direction 7. As shown in FIG. In other words, the pocket 16 is positioned on the imaginary straight line V1 along the front-rear direction 6 passing through the center 21C of the short side 21 . The center of the pocket 16 in the left-right direction 7 does not necessarily have to be positioned on the imaginary straight line V1.

Further, the pocket 16 is positioned forwardly (an example of one direction) with respect to the center 22C of the long side 22 of the first sheet 14 and the second sheet 15 in the front-rear direction 6 . In other words, the pocket 16 is located in front of the imaginary straight line V2 along the left-right direction 7 passing through the center 22C of the long side 22 in the front-rear direction 6. As shown in FIG. That is, virtual straight line V2 does not pass through pocket 16 .

The writing area 20 is positioned over the entire upper surface of the first sheet 14 in the left-right direction 7 . The entry area 20 is positioned asymmetrically with the pocket 16 with respect to the imaginary straight line V2 in the front-rear direction 6 . In other words, the distances in the front-rear direction 6 between the front and rear ends of the writing area 20 and the imaginary straight line V2 are different from the distances in the front-rear direction 6 between the front and rear ends of the pocket 16 and the imaginary straight line V2.

In addition, the entry area 20 is positioned asymmetrically with respect to the imaginary straight line V2 in the front-rear direction 6 with respect to each projection 18 . In other words, the distances in the front-rear direction 6 between the front and rear ends of the writing area 20 and the imaginary straight line V2 are different from the distances in the front-rear direction 6 between the front and rear ends of each projection 18 and the imaginary straight line V2.

The pocket 16 and each projection 18 are positioned asymmetrically with respect to the imaginary straight line V1 in the left-right direction 7 . In the present embodiment, the pocket 16 is located at the center 21C of the short side 21, and the protrusions 18 are located on both sides of the pocket 16 in the left-right direction 7 so as not to overlap the pocket 16. As shown in FIG. In this embodiment, the projections 18 are at the same position in the front-rear direction 6 and at symmetrical positions with respect to the virtual straight line V1 in the left-right direction 7 .

In addition, each projection 18 is positioned 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 convex portion 18 is located behind the virtual straight line V2 in the front-rear direction 6. As shown in FIG. That is, the virtual straight line V2 does not pass through each convex portion 18 .

[Binding of PTP sheets 10]
The binding state of the PTP sheets 10 will be described below with reference to FIGS. The two PTP sheets 10 that are tied together have the same configuration, but for convenience of explanation, the PTP sheet 10 that is positioned lower in the tied state will be referred to as the PTP sheet 10L, and the PTP sheet 10 positioned above will be referred to as the PTP sheet 10L. 10 is called a PTP sheet 10H. Further, L and H are added to the reference numerals indicating the members constituting the PTP sheets 10L and 10H for explanation.

The two PTP sheets 10L and 10H are superimposed so that the first sheets 14L and 14H face each other. In the two PTP sheets 10L and 10H, the short sides 21L and 21H face each other, and the long sides 22L and 22H face each other. That is, in the tying state shown in FIG. 6, the rear short side 21L of the PTP sheet 10L and the front short side 21H of the PTP sheet 10H appear facing each other. That is, the PTP sheet 10L and the PTP sheet 10H are turned inside out so that one of the front and back directions 6 is reversed. A PTP sheet 10H is placed over the PTP sheet 10L.

As shown in FIG. 1, in the PTP sheets 10H, 10L, the pockets 16L, 16H and the projections 18L, 18H are positioned asymmetrically with respect to the imaginary straight lines V1, V2. Therefore, in the tying state, the facing pockets 16L, 16H and the facing projections 18L, 18H are in a positional relationship in which none of them come into contact with each other.

In FIGS. 7 and 8, the convex portions 18L are positioned on both outer sides in the left-right direction 7 with respect to the pocket 16H. Each convex portion 18H is aligned on both outer sides in the left-right direction 7 with respect to the pocket 16L. Each convex portion 18L, 18H is in contact with the first sheet 14L, 14H of the facing PTP sheets 10L, 10H, respectively.

In the bound state, the PTP sheets 10L and 10H are curved so as to swell in the vertical direction 5. As shown in FIG. As a result, the first seats 14L and 14H define a space 30 in which the centers in the left-right direction 7 are farthest apart. In this embodiment, the height of the pockets 16L and 16H protruding from the first sheets 14L and 14H in the vertical direction 5 and the height of the protrusions 18L and 18H protruding from the first sheets 14L and 14H in the vertical direction 5 are equivalent. However, in the space 30, the projections 18L and 18H are in contact with the first sheets 14L and 14H on both sides of the pockets 16L and 16H in the left-right direction 7. It does not contact the opposing PTP sheets 10L and 10H.

Also, as shown in FIG. 1, in each of the PTP sheets 10L and 10H, the writing areas 20L and 20H are positioned asymmetrically with respect to the pockets 16L and 16H and the projections 18L and 18H with respect to the imaginary straight line V2. Therefore, as shown in FIGS. 7 and 8, the writing areas 20L, 20H do not face the pockets 16L, 16H and the protrusions 18L, 18H in the bound state. Therefore, in the tying state, the projections 18L, 18H contact the first sheets 14L, 14H at positions different from the writing areas 20L, 20H.

As shown in FIG. 6, an elastic annular belt such as a rubber band 31 may be wrapped around the outside of the PTP sheets 10L and 10H in the tied state in order to maintain the tied state. In general, the rubber band 31 or the like is wound around the center of the long sides 22L, 22H of the PTP sheets 10L, 10H, that is, near the imaginary straight line V2. Since the pockets 16L, 16H and the projections 18L, 18H are not positioned on the imaginary 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 together. At this time, the bending of the PTP sheets 10L and 10H increases the rigidity, and the long sides 22L and 22H of the PTP sheets 10L and 10H are easily maintained in a straight shape. In other words, the PTP sheets 10L and 10H are not easily deformed so that the vicinity of the imaginary straight line V2 approaches each other. Moreover, even if the PTP sheets 10L and 10H are slightly deformed by the elastic force of the rubber band 31, that is, even if the short sides 21L and 21H are deformed so as to return to a linear shape, the pocket 16L, The curvature of the PTP sheets 10L and 10H is maintained by the contact of the 16H with the opposing PTP sheets 10L and 10H.

[Action and effect of the present embodiment]
According to this embodiment, in the PTP sheets 10L and 10H in the tied state, the centers of the first sheets 14L and 14H are curved in directions away from each other. The space 30 in which the bending is performed is widened as compared with the case where the bending is not performed. This makes it difficult for the first sheets 14L, 14H and the facing pockets 16L, 16H to come into contact with each other. As a result, the pockets 16L and 16H of the PTP sheets 10L and 10H in the tied state can be protected from being pressed by an external force.

In addition, since the stiffness (rigidity) of the first sheets 14L and 14H increases due to the curvature of the first sheets 14L and 14H, even if the rubber bands 31 and the like are wrapped around the PTP sheets 10L and 10H in the tied state, the rubber bands 31 and the like do not The first sheets 14L and 14H are less likely to deform due to the force of (1).

In addition, since the pockets 16L, 16H are positioned in the center of the first sheets 14L, 14H in the left-right direction 7, the pockets 16L, 16H are located at the farthest distance between the facing first sheets 14L, 14H in the tying state. is located.

In addition, since the pockets 16L and 16H are positioned at the center in the front-rear direction 6, that is, shifted forward with respect to the imaginary straight line V2, the pockets 16L and 16H do not come into contact with each other in the tying state. Note that the pockets 16L and 16H may be shifted in any direction, forward or backward, with respect to the imaginary straight line V2.

In addition, since the writing areas 20L, 20H are located in the center of the front-rear direction 6, i.e., at positions asymmetrical to the pockets 16L, 16H with respect to the imaginary straight line V2, the pockets 16L, 16H and the writing areas 20L, 20H are aligned in the tied state. do not abut.

In addition, since the pockets 16L, 16H and the projections 18L, 18H are located at the center in the left-right direction 7, i.e., at asymmetrical positions with respect to the imaginary straight line V1, the projections 18L, 18H face each other in the tying state. 14L and 14H, the pockets 16L and 16H do not contact the facing first sheets 14L and 14H, or even if they do contact, the load on the pockets 16L and 16H is reduced.

The pockets 16L and 16H are located at the center in the left-right direction 7, and the projections 18L and 18H are located on both sides of the pockets 16L and 16H in the left-right direction 7 and do not overlap the pockets 16L and 16H. Therefore, in the space 30 in the tying state, the convex portions 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. are less likely to come into contact with the opposing first sheets 14L and 14H.

In addition, the pockets 16L and 16H are positioned at the center of the front-rear direction 6, i.e., are shifted forward with respect to the imaginary straight line V2, and the projections 18L and 18H are positioned at rearward positions with respect to the imaginary straight line V2. In the space 30 in the tying state, the convex portions 18L and 18H abut against the opposing first sheets 14L and 14H at positions relatively close to the pockets 16L and 16H.

[Modification]
The arrangement and number of the pockets 16 and protrusions 18 in the above-described embodiment are examples, and may be changed as appropriate by those skilled in the art. Also, the entry area 20 may not necessarily be provided. Further, the outer shape of the PTP sheet 10 in plan view is not limited to a rectangle, and may be a quadrangle such as a square, a parallelogram, or a trapezoid, for example. Further, the front-rear direction 6 and the left-right direction 7 of the PTP sheet 10 are relative.
