Description

PTP package

The present invention relates to a PTP package, and more particularly to a PTP package in which extrusion (extrusion) is improved when a package such as a tablet or a capsule is extruded from a PTP package.

A package of PTP (Press Through Package) has been widely used for packaging such as tablets or capsules.

The PTP packaging system has a structure in which a package is placed in a bag portion formed in a PTP sheet, and then sealed with a cover material that is easily crushed.

When the packaged object is extruded from the PTP package, the packaged object is pressed by the arc-shaped pocket top facing the cover material side, and the cover material is squeezed and extruded.

Regarding the shape of such a PTP package, for example, Patent Document 1 is known.

As shown in FIG. 11, the PTP package 101 described in Patent Document 1 is composed of a sheet container 103 including a housing portion 120 (for housing the pharmaceutical preparation 102) and a lid member 104 for sealing the housing portion 120.

The side wall 121 of the accommodating portion 120 is erected obliquely with respect to the lid member 104 in a direction, and the cross-sectional shape of the space surrounded by the accommodating portion 120 and the lid member 104 is slightly rhombic.

By making the cross-sectional shape of the space for accommodating the pharmaceutical preparation 102 slightly rhombic in this manner, when the top surface 122 of the accommodating portion 120 is pressed toward the lid member 104 side, the pharmaceutical preparation 102 can be taken out. The accommodating portion 120 is easily collapsed, deformed, and compressed to improve the opening property of the cover member 104.

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2008-68873

However, in the PTP package 101 of the patent document 1, the side wall 121 of the accommodating portion 120 accommodating the pharmaceutical preparation 102 is erected obliquely with respect to the lid member 104, so that the deformation of the accommodating portion 120 is facilitated and improved. The PTP package 101 has an unsealing property, but the shape of the top surface 122 of the accommodating portion 120 is not particularly considered. Therefore, it is desirable to have a PTP package which is easy to press against the shape of the top surface of the container and which further improves the squeezing property when the pharmaceutical preparation is taken out.

Further, for all people, especially elderly people who often use pharmaceutical preparations, a PTP package having a general design that can easily take out a pharmaceutical preparation from a package is desired.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a PTP package which is improved in squeezability when a packaged article is taken out from a PTP package as a general-purpose design.

Another object of the present invention is to provide a PTP package having a shape in which a finger is easily pressed.

The above-mentioned problem is solved by the PTP package according to the present invention comprising: a PTP sheet having a convex pocket portion protruding toward the surface side of the sheet and capable of accommodating the packaged object in the pocket portion, and sealing The bag portion is bonded to the lid member on the back surface of the PTP sheet, and the bag portion is formed on a side surface of the side surface of the sheet surface and a top surface of the end portion of the side wall opposite to the lid member. The top surface is inclined with respect to a portion of the cover material surrounded by the side wall.

In this way, since the top surface of the bag portion is inclined with respect to the portion surrounded by the side wall in the lid member, when the top portion of the bag portion is pressed toward the lid member side, the extrusion force is easily concentrated on the lid portion of the bag portion. The nearest part of the material side is inclined so that the pocket portion can be easily recessed. By easily sagged the bag portion, the packaged article accommodated in the bag portion is easily squeezed out of the lid member and extruded.

That is, it is possible to provide a PTP package which has a squeezing property when the packaged article is taken out from the PTP package and has a generalized design.

In this case, it is preferable that the side wall is inclined with respect to a portion surrounded by the side wall of the cover member so as to be located inside the bag portion.

Since it is configured in this manner, when the top of the bag portion is pressed toward the cover material side, the side wall of the bag portion is easily inverted to the inner side, so that the bag portion can be more easily recessed.

That is, the packaged article can be further easily taken out from the PTP package.

In this case, the side wall preferably includes a first portion which is formed to be the lowest in the side wall, and a second portion which is located on the opposite side to the first portion via the top surface and which is formed to be higher than the first portion. .

Since it is comprised in this way, when the top surface of the bag part is extruded, the extrusion force tends to concentrate on the 1st part which formed the minimum in a side wall, and it can make it easy to dent. That is, the packaged article can be further easily taken out from the PTP package.

In this case, it is preferable that the second portion of the side wall is formed to be the highest.

In this manner, since the second portion located on the opposite side with respect to the first portion formed to be the lowest portion is formed to be the highest, when the top surface of the bag portion is extruded, the extrusion force is more likely to be concentrated on the side wall. In the first part, the bag portion is easily recessed.

In this case, it is preferable that the top surface is formed in a substantially flat shape.

As described above, since the top surface is formed in a flat shape, it is possible to provide a PTP package having a shape in which the finger is easily pressed against the top surface of the bag portion.

In this case, it is preferable that the top surface is formed of any one selected from the group consisting of a substantially circular shape, a substantially elliptical shape, and a substantially polygonal shape.

Since it is constituted in this manner, it can be provided to be appropriately changed according to the shape of the pharmaceutical preparation. A PTP package in the shape of the top of the bag.

Further, it is possible to provide a PTP package in which the shape of the top surface of the bag portion which is pressed by the finger can be appropriately changed according to the user's intention, and the packaged article can be easily taken out.

In this case, the packaged product is preferably a pharmaceutical preparation.

As described above, when the packaged product is a pharmaceutical preparation, the elderly person who uses the pharmaceutical preparation can easily take out the pharmaceutical preparation from the PTP package, and therefore, it can be provided as a PTP package having a generalized design.

At this time, the angle θ between the top surface and the portion of the lid member surrounded by the side wall is preferably 5° ≦ θ ≦ 70°.

Thus, since the angle θ is 5° ≦ θ ≦ 70°, it is possible to form the operability in consideration of the user's use of the finger to press the top surface of the bag portion, and the squeezing property when the packaged object is taken out from the PTP package body. Angle set PTP package.

Further, by setting the angle θ with a lower limit of 5°, it is possible to improve the squeezing property when the packaged article is taken out from the PTP package.

Further, by setting the angle θ with an upper limit of 70°, it is possible to realize the production of a PTP package in consideration of the range in which the pharmaceutical preparation can be accommodated.

At this time, the above θ is more preferably 5° ≦ θ ≦ 20°.

As described above, since the angle θ is 5° ≦ θ ≦ 20°, the top surface of the PTP package can be set to a shape in which the finger is more easily pressed by setting the angle θ with the upper limit of 20°.

At this time, the above θ is more preferably 10° ≦ θ ≦ 15°.

As described above, since the angle θ is 10° ≦ θ ≦ 15°, by setting the angle θ by 10° as the lower limit value, the squeezing property when the packaged article is taken out from the PTP package can be further improved. Moreover, by setting the angle θ with an upper limit of 15°, it is possible to realize the manufacture of a PTP package in consideration of the manufacturing cost using the original equipment.

According to the PTP package of the present invention, the top surface of the bag portion is opposite to the cover material When the portion surrounded by the side wall is inclined, when the top of the bag portion is pressed toward the lid member side, the extrusion force tends to concentrate on the portion of the bag portion that is inclined toward the lid member side, so that the bag portion can be easily recessed. By easily sagged the bag portion, the packaged article accommodated in the bag portion is easily squeezed out of the lid member and extruded.

That is, it is possible to provide a PTP package which has a squeezing property when the packaged article is taken out from the PTP package and has a generalized design.

Further, since the top surface of the PTP package is formed in a flat shape, it is possible to provide a PTP package having a shape in which a finger is easily pressed against the top surface.

Fig. 11 is an explanatory view of a PTP package of a conventional example.

The present invention relates to a PTP package according to the invention, characterized in that it comprises a bag portion for accommodating a pharmaceutical preparation, and a top surface of the bag portion is inclined with respect to the lid member.

As shown in FIG. 1, the PTP package 1 of the present embodiment is mainly composed of a PTP sheet 3 containing the pharmaceutical preparation 2 and a lid member 4 bonded to the bottom surface side of the PTP sheet 3.

In addition, when viewed in FIG. 1, the front side in the longitudinal direction of the PTP package 1 becomes the front side.

The PTP package 1 is a package in which the pharmaceutical preparation 2 is extruded from the PTP sheet 3 side to the lid member 4 side and taken out.

In addition, although the shape of the PTP package 1 is formed in a substantially rectangular shape, the shape is not limited thereto, and may be appropriately changed depending on the shape or the number of the pharmaceutical preparation 2 or the like.

The pharmaceutical preparation 2 is composed of a solid preparation such as a tablet or a capsule.

In particular, the pharmaceutical preparation 2 of the present embodiment is a fragile solid preparation such as an orally disintegrating preparation, and may be contained in a PTP package, and may be easily broken by extrusion force when the pharmaceutical preparation is extruded.

Moreover, the packaged article accommodated in the PTP package 1 is not limited to the pharmaceutical preparation 2, and various modifications are possible. For example, solid foods, various decorations, or various kinds of materials such as buttons and batteries can also be used. Live goods and the like as a packaged object.

As shown in FIG. 2, the pharmaceutical preparation 2 is accommodated in the bag portion 20 which will be described later in the PTP sheet 3 so that the direction of the strip is substantially horizontal with respect to the lid member 4.

The PTP sheet 3 is formed into a substantially rectangular transparent or colored resin or metal sheet, and is mainly composed of a sheet substrate portion 10 on which a planar substrate is formed and a surface side of the sheet substrate portion 10 as shown in FIG. A plurality of protruding pockets 20 are formed.

One end of the sheet substrate portion 10 in the longitudinal direction is wider than the other end, and a handle portion 11 that is gripped by the user when the PTP package 1 is processed is formed. Further, the shape of the sheet substrate portion 10 is not particularly limited as long as it can be provided to the user, and can be changed.

The specific raw material of the PTP sheet 3 is preferably PVC (polyvinyl chloride), PP (polypropylene), PCTFE (polychlorotrifluoroethylene), and aluminum. Further, it is not limited to these raw materials, and a well-known resin or metal material can also be used.

In order to ensure rigidity and maintain good formability, the PTP sheet 3 is formed by setting the thickness before molding to a range of about 150 to 300 μm.

In particular, it is preferred to form the thickness before forming to a range of about 200 to 250 μm.

By this means, it is possible to easily form a sheet which does not cause wrinkles and which is excellent in appearance, using the original machine.

In addition, the thickness of the PTP sheet 3 is not limited to about 150 to 300 μm, and can be appropriately changed. The thickness of the PTP sheet 3 is not damaged as long as it is transported, and the degree of deformation may be generated when the pocket portion 20 of the PTP sheet 3 is extruded toward the lid member 4 side.

The cover member 4 is made of an aluminum material which is formed into a substantially rectangular shape, and is bonded to the bottom surface of the PTP sheet 3 so as to seal the bag portion 20.

When aluminum is used as the material of the lid member 4, the moisture resistance and the light-shielding property of the PTP package 1 are improved, which is preferable, but it is not particularly limited to aluminum. For example, a cellophane, a well-known resin material such as a polyamide resin, or the like can be used as a raw material of the lid member 4.

In order to ensure rigidity and to maintain good sealing properties, the lid member 4 is sealed by setting the thickness before sealing to a range of about 15 to 20 μm. In particular, it is preferable to perform sealing by setting the thickness before sealing to about 17 to 20 μm. This is because, in this way, the container having high airtightness is made to have good reproducibility and is easy to produce stably.

Further, the thickness of the lid member 4 is not limited to about 15 to 20 μm, and can be appropriately changed. The thickness of the lid member 4 is not to be damaged when transported, and the like, and when the lid material 4 is squeezed from the PTP package 1 to extrude the pharmaceutical preparation 2, it is easy to be crushed.

As shown in FIG. 1, the PTP package 1 is provided with ten pockets 20, specifically, five in the longitudinal direction of the PTP package 1 at a predetermined interval, and five pockets 20 are arranged along the same The direction in which the longitudinal direction of the PTP package 1 is perpendicular is set to two rows.

Further, the number and arrangement of the bag portions are of course not limited thereto, and can be changed. Further, all of the bag portions 20 are not limited to the same shape, and the shape of the bag portion 20 may be different depending on the shape of the pharmaceutical preparation 2.

As shown in FIG. 2, the pocket portion 20 has a substantially circular cross section, and the pocket portion 20 is formed by a side wall 21 erected on the surface of the sheet substrate portion 10 and a top surface 22 provided at an upper end portion of the side wall 21. Composition.

Further, although the cross section of the bag portion 20 is formed in a substantially circular shape, the present invention is not limited thereto, and may be appropriately changed depending on the shape of the pharmaceutical preparation 2.

The side wall 21 corresponds to the side portion of the pocket portion 20, and has a substantially conical shape centering on the central axis 23a of the pocket portion 20 in the vertical direction and a shape in which the upper end is cut by the inclined surface, and extends from the surface of the sheet substrate portion 10 to the upper side. .

Further, the entire side wall 21 is inclined toward the inner side of the pocket portion 20, that is, the side of the central axis 23a of the pocket portion 20 at a specific angle with respect to the direction of the vertical cover member 4.

At this time, as shown in FIG. 2, when the cross section of the pocket portion 20 is observed in the longitudinal direction of the PTP package 1, the grounding angle α formed by the side wall 21 and the cover member 4 is set at 30 ° ≦ α < 90° range.

By setting the ground angle α to an acute angle in this manner, when the pocket portion 20 is extruded toward the lid member side, the side wall 21 is easily inverted to the inner side, so that the pocket portion 20 can be easily recessed.

In particular, it is preferable to set the range of the ground angle α to 60° ≦ α < 90°.

By this means, the cross-sectional area of the bag portion 20 can be appropriately adjusted according to the shape of the pharmaceutical preparation 2, and a large amount of the pharmaceutical preparation 2 can be accommodated in the PTP package 1.

For example, when the slightly elliptical pharmaceutical preparation 2 is vertically stored in the direction of the strip, the cross-sectional area of the pocket portion 20 can be adjusted to be small by increasing the ground angle α. The PTP package 1 forms a plurality of pockets 20 so that the pharmaceutical preparation 2 can be accommodated.

Further, the range of the ground angle α in the present embodiment is set to 30° ≦ α < 90°, but it is not limited as long as it is within the range in which the pharmaceutical preparation 2 can be accommodated. For example, in order to secure the rigidity of the side wall 21, the ground angle α may be set to 90°.

As shown in FIG. 2, the first portion 21a having the lowest height and the second portion 21b having the highest height are formed on the side wall 21, and the first portion 21a and the second portion 21b are located opposite each other across the top surface 22. The opposite side of the diameter direction.

As seen in FIG. 1, the first portion 21a is located on the opposite side of the handle portion 11 in the longitudinal direction of the PTP package 1, and is located in a direction orthogonal to the longitudinal direction of the PTP package 1. A substantially central portion of the pocket portion 20.

As seen in FIG. 1, the second portion 21b is located on the side of the handle portion 11 in the longitudinal direction of the PTP package 1, and is located in the pocket portion in the direction orthogonal to the longitudinal direction of the PTP package 1. The roughly central part of 20.

The first portion 21a and the second portion 21b of the side wall 21 are disposed such that the center 22a of the top surface 22 is placed on a line connecting a portion where the first portion 21a and the top surface 22 intersect with the portion where the second portion 21b and the top surface 22 intersect. .

The entire side wall 21 of the present embodiment is oriented at a ground angle α with respect to the lid member 4. The inside of the bag portion 20 is inclined, but the present invention is not limited thereto and can be changed.

For example, the first portion 21a and the second portion 21b of the side wall 21 may be formed to be inclined toward the inner side of the pocket portion 20, and the other portions may extend in the direction perpendicular to the vertical cover member 4. Further, only the first portion 21a of the side wall 21 may be inclined toward the inner side of the pocket portion 20. Further, the ground angle α may be a different value on the sides 21a and 21b.

A corner portion 24 that abuts against the surface of the sheet substrate portion 10 at the lower end portion of the side wall 21 is given a radius of curvature R. Therefore, the rigidity of the corner portion 24 is ensured, and the formability is kept good.

Further, the radius of curvature R of the corner portion 24 can be appropriately changed in size, and the radius of curvature R can be locally imparted to the corner portion 24 over the entire circumference. The corner radius 24 may not be given a radius of curvature R.

The top surface 22 corresponds to the upper portion of the pocket portion 20 and is formed in a substantially circular flat shape.

The shape of the top surface 22 of the present embodiment is formed into a substantially circular shape according to the shape of the pharmaceutical preparation 2, but the shape is not limited thereto, and may be substantially elliptical in addition to a substantially circular shape.

When the shape of the top surface 22 is a substantially circular shape or a substantially elliptical shape, the shape of the top surface 22 of the PTP package 1 can be easily pressed by a user with a finger.

Further, the shape of the top surface 22 can be appropriately changed to a substantially semi-elliptical shape, a polygonal shape, or the like.

The top surface 22 can be changed without particular limitation as long as it is formed so that the thumb is easily pressed. For example, it may be 3.5 cm or less in diameter, more preferably 2 cm or less in diameter. If the top surface 22 is substantially circular, it may have a diameter of about 0.1 to 3.5 cm, more preferably about 0.1 to 2 cm in diameter, still more preferably about 0.3 to 1.5 cm.

As shown in FIGS. 1 and 2, the top surface 22 is inclined toward the front side at a specific angle with respect to the lid member 4 in the longitudinal direction of the PTP package 1. In other words, the top surface 22 is formed in a substantially circular flat shape centering on the central axis 23b in which the central axis 23a is inclined toward the front side with respect to the lid member 4 at a specific angle.

When the inclination angle formed by the top surface 22 and the lid member 4 is θ, in other words, when the inclination angle formed by the central axis 23a and the central axis 23b is θ, as shown in FIG. 2 It is shown that the inclination angle θ is set in the range of 5° ≦ θ ≦ 70°.

In particular, it is preferable to set the range of the inclination angle θ to 5° ≦ θ ≦ 20°.

By setting the inclination angle θ of the present embodiment at a lower limit of 5°, it is possible to improve the squeezing property when the pharmaceutical preparation 2 is taken out from the PTP package 1 .

Further, by setting the inclination angle θ with the upper limit of 20°, the PTP package 1 can make the shape of the top surface 22 more easily pressed by the user with the finger.

Further, it is preferable that when the inclination angle θ of the bag portion is set to 5° ≦ θ ≦ 15°, the manufacturing range can be considered in consideration of the manufacturing cost.

Further, preferably, when the inclination angle θ of the pocket portion is set to 10° ≦ θ ≦ 15°, the pocket portion can be further recessed.

In addition, the inclination angle θ is not particularly limited as long as the inclination angle θ at which the bag portion is easily recessed is set within the range in which the pharmaceutical preparation 2 can be accommodated.

The top surface 22 of the present embodiment is inclined to the side opposite to the handle portion 11 at an inclination angle θ with respect to the lid member 4 in the longitudinal direction. However, the present invention is not limited thereto, and may be directed to the handle portion 11 side in the longitudinal direction. It is inclined to one side of the direction orthogonal to the longitudinal direction.

Further, although the entire top surface 22 of the present embodiment is inclined with respect to the lid member 4, the present invention is not limited thereto, and the top surface 22 may be partially inclined with respect to the lid member 4. That is, only the upper surface side of the top surface 22 may be inclined with respect to the lid member 4, or the top surface 22 may be provided with an inclined portion inclined with respect to the lid member 4.

Further, although the top surface 22 of the present embodiment is inclined with respect to the lid member 4, the present invention is not limited thereto, and may be inclined with respect to the planar sheet substrate portion 10, or may be opposed to the lid member of the side wall 21. The plane formed by the ends of the 4 sides is inclined.

The corner portion 25 where the top surface 22 abuts against the side wall 21 is formed in a substantially circumferential shape, and is provided with a radius of curvature R throughout the entire circumference. Therefore, the rigidity of the corner portion 25 is ensured and the formability is kept good. Moreover, since the diagonal portion 25 is given the radius of curvature R, the user presses the finger against it. When the top surface 22 of the bag portion 20 is used, the finger has no discomfort.

Further, the radius of curvature R of the corner portion 25 can be appropriately changed in size, and the radius of curvature R can be locally imparted to the corner portion 25 over the entire circumference. The corner radius 25 may not be given a radius of curvature R.

Although the top surface 22 of this embodiment is formed in a substantially flat shape, as another embodiment, unevenness may be additionally provided on the surface of the top surface 22. By providing the unevenness on the surface of the top surface 22 as described above, when the user extrudes the top surface 22 with a finger, the unevenness of the top surface 22 is prevented from slipping. Therefore, it becomes easy to extrude the top surface 22 with a finger.

Further, by imparting irregularities to the top surface 22, the flexibility of the top surface 22 is improved.

As the uneven shape given to the top surface 22, for example, a fingerprint shape, a dot shape, a star shape, or the like can be employed.

In particular, by imparting a fingerprint shape at substantially the center of the surface of the top surface 22, the top surface 22 can be easily extruded by fingers, and the rigidity of the top surface 22 can be ensured, so that the user can easily confirm the top surface from the PTP package 1. 22 location. The specific fingerprint shape may be a shape in which the irregularities are radially (concentrically) extended.

<Example>

Hereinafter, embodiments of the invention will be described in detail. Furthermore, the present invention is not limited to the embodiment.

The configuration of this embodiment of the PTP package 1 is as follows.

Pharmaceutical preparation 2: Gaster (registered trademark) D ingot 20 mg (manufactured by Astellas Pharmaceutical Co., Ltd.)

PTP sheet 3: PVC 200 μm (VSS-F110, manufactured by Sumitomo Bakelite Co., Ltd.)

Cover material 4: Aluminum 17μm (pure, manufactured by Light Aluminum Foil Co., Ltd.)

The PTP package 1 was manufactured by using a blister packaging machine (FBP-600UC, manufactured by CKD Co., Ltd.) to form the PTP sheet 3 from PVC 200 μm. The pharmaceutical preparation 2 was placed in the PTP sheet 3, and the lid member 4 made of aluminum 17 μm was sealed on the back surface of the PTP sheet 3.

The molding conditions of the blister packaging machine are shown in Table 1 below.

When the bag portion 20 of the PTP sheet 3 is formed, the shape of the forming plug of the blister packaging machine is changed, and the inclination angle θ of the bag portion 20 is formed to be 5°, 10°, and 15°, and The first embodiment, the second embodiment, and the third embodiment of the PTP package 1 are respectively provided.

Next, using the PTP package 1 of Example 1, Example 2, and Example 3 in which the inclination angle θ of the bag portion 20 is different, the load when the bag portion 20 is extruded toward the lid member 4 side is measured.

Further, as a control group, a PTP package in which the inclination angle θ of the bag portion 20 was 0° was prepared according to the conditions of Table 1.

The test method is as follows.

The top surface 22 of each PTP package 1 was subjected to a load which was extruded in the vertical direction toward the lid member 4 side by using a universal testing machine (AGS-J, manufactured by Shimadzu Corporation). The extrusion load of the pharmaceutical preparation 2 from the extrusion of each PTP package 1 to break the lid member 4 was measured.

The extrusion speed was set to 15 mm/min, and an extruded rod (SUS: Steel Use Stainless) having a diameter of 7.93 mm was used. Three tests were performed on each PTP package 1.

The results of the extrusion load test are shown in Fig. 3 and Table 2 below.

In FIG. 3, the small peak of the extrusion load (Force) indicates the load when the top surface 22 of the PTP package 1 is recessed toward the cover member 4 side, and the large peak of the extrusion load indicates the pharmaceutical preparation 2 from the bag portion 20. The load when the cover material 4 is broken is extruded.

When an attempt was made to evaluate the average load when the top surface 22 was recessed toward the lid member 4 side, it was confirmed that the extrusion load of the control group was large, and the extrusion load of Example 1 was small.

In other words, it can be confirmed that as the inclination angle θ of the bag portion 20 becomes larger, the top surface 22 of the bag portion 20 can be easily recessed toward the lid member 4 side.

Further, as shown in Fig. 3, the "-" in Table 2 means that the peaks of the load when the top surface 22 is recessed are not confirmed in the embodiment 2 and the third embodiment.

Next, when an attempt was made to evaluate the average load when the cover material 4 was broken, it was confirmed that the control group became the maximum extrusion load, and the extrusion load was small in the order of Example 1, Example 2, and Example 3.
