Description

[Technical Field]

[0001] The present invention relates to a PTP (press-through pack) package and a PTP-packaged medicine. [Background technology]

[0002] Known examples of packaging forms for medicines such as tablets and the medicines to be packaged include PTP packages and PTP-packaged medicines disclosed in Patent Document 1 and Patent Document 2. The medicine container disclosed in Patent Document 1, excluding the dispenser portion, comprises a first cover sheet having spaced circular openings for receiving the medicines and recessed protrusions formed on the outside for accommodating the medicines, and a second cover sheet having a circular closing portion that is larger in radius than the openings and is easily torn, which closes the openings of the first cover sheet.

[0003] Furthermore, the packaging body disclosed in Patent Document 2 comprises a storage section formed in a dome shape that bulges out toward the front side and stores the contents, a resin storage sheet having a flat portion that surrounds the storage section, half of which is arc-shaped and the other half is teardrop-shaped, and a lid material that is joined to the flat portion on the back side and closes the opening of the storage section, and the storage section has at least one depression on the surface. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] U.S. Patent No. 2,415,859 (Figs. 5 and 7) [Patent Document 2] Japanese Patent Application Publication No. 2018-122913 Summary of the Invention [Problem to be solved by the invention]

[0005] The medicine container disclosed in Patent Document 1 has the problem that the act of pushing out the medicine can be a burden, especially for elderly people, and therefore a medicine dispenser is required. In addition, when pushing out the medicine, part of the second cover sheet of the PTP package may stick to the medicine, which can lead to the person accidentally swallowing part of the second cover sheet when taking the medicine.

[0006] The package disclosed in Patent Document 2 has the problem that when two packages are stacked with the storage sections facing each other, half of the storage section is teardrop-shaped, increasing the surface area of ​​the storage section, and therefore it is necessary to newly manufacture an existing mold for manufacturing some of the drugs.In addition, there is also the problem that it is difficult to mold small depressions in the storage section when manufacturing a resin storage sheet by pressure molding or vacuum molding.

[0007] In order to solve the above-mentioned problems, the present invention aims to provide a PTP package and a PTP-packaged medicine that do not increase costs and that allow round medicines to be taken without worry and with ease. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the PTP package and PTP-packaged medicine described in claim 1 comprise a storage section that protrudes from the front side and stores a circular medicine, a first sheet having a flat section that surrounds the storage section, and a second sheet that is joined to the flat section on the back side and closes the opening of the storage section, and at least a portion of the periphery of the storage section when viewed from above is formed in a straight line.

[0009] In the PTP package and PTP-packaged medicine according to claim 2, the periphery of the container in a top view is formed in a regular quadrilateral, regular hexagonal, or regular octagonal shape excluding the corners.

[0010] In addition, in the PTP packaging body and PTP-packaged medicine described in claim 3, half of the periphery of the storage section when viewed from above is arc-shaped, and the remaining half is formed in the shape of a half regular square, regular hexagon, or regular octagon, excluding the corners. [Effects of the Invention]

[0011] According to the present invention, in the PTP package and PTP-packaged medicine described in claim 1, at least a part of the periphery of the storage section that protrudes from the surface and stores a circular medicine is formed in a straight line when viewed from above, so that the straight line portion bends easily when pushing out the circular medicine, making it easy to push out the medicine. Furthermore, since no recess is provided, costs do not increase.

[0012] In addition, the PTP package and PTP-packaged medicine described in claim 2 have a top view perimeter of a storage section that protrudes toward the surface and contains a circular drug, and is formed in a regular square, regular hexagon, or regular octagon, excluding the corners. This allows the four, six, or eight straight sections to bend easily when pushing out the circular drug, making it easy to push out the circular drug. Furthermore, because the four, six, or eight straight sections generally bend differently, the circular drug can be pushed out from near the edge of the opening of the second sheet, preventing the entire opening of the second sheet from breaking, thereby preventing part of the second sheet from being attached to the drug. Furthermore, when stacking two PTP packages and PTP-packaged medicines with the storage sections facing each other, if the top view perimeter of the storage section is formed in a shape other than a square, excluding the corners, the area of ​​the storage section on the surface side is smaller than that of a square, making it easier to stack them. Furthermore, if additional processing of an existing mold is possible, costs can be reduced substantially. Furthermore, the lack of a recess also reduces costs.

[0013] Furthermore, in the PTP package and PTP-packaged medicine described in claim 3, half of the circumference of the storage section that protrudes toward the surface and stores a circular medicine is arc-shaped in a top view, and the remaining half is formed into a half square, regular hexagon, or regular octagon, excluding the corners. This allows the linear portion to bend easily when pushing out the circular medicine, making it easy to push out the circular medicine. Furthermore, because the circular medicine can be pushed out from near the edge of the opening of the second sheet, the entire opening of the second sheet is not torn, preventing part of the second sheet from being attached to the medicine. Furthermore, when stacking two PTP packages and PTP-packaged medicines with the storage sections facing each other, the area of ​​the storage section on the surface side is smaller than that of a square, making it easier to stack them. Furthermore, if additional processing of an existing mold is possible, costs can be reduced. Furthermore, the absence of a recess also reduces costs. [Brief explanation of the drawings]

[0015] Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. In order to facilitate understanding, circular medicines (hereinafter referred to as medicines) are illustrated in solid lines in Figures 1, 2, 5, and 6.

[0016] (First embodiment) A first embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1, 2, 3, and 4, a PTP package and a PTP-packaged medicine 1 include a storage section 3 that protrudes from the front surface (the upper surface in Figures 1 and 2) and stores a medicine 2 such as a tablet, a first sheet 5 made of a thermoplastic resin such as polyvinyl chloride resin and having a flat surface 4 that surrounds the storage section 3, and a second sheet 6 made of aluminum foil or the like that is joined to the flat surface 4 on the back surface (the lower surface in Figures 1 and 2) and closes an opening 31 of the storage section 3, and the periphery 34 of the storage section 3 when viewed from above is formed in the shape of a regular rectangle excluding the corners.

[0017] As shown in Figures 2 and 3, when the central portion 33 of the upper surface 32 of the storage section 3 is pressed with the thumb (not shown) to push out the drug 2, as shown in Figure 4, the force F of the thumb (not shown) is generally applied to a position away from the central portion 33 (to the left of the central portion 33 in the case of Figure 4), and is applied to the left side portion 62 of the central portion 61 of the second sheet 6 that blocks the opening 31 of the first sheet 5 via the drug 2.

[0018] As shown in Figure 4, when force F is applied to the left side 62 of the central portion 61 of the second sheet 6, the left side 62 of the second sheet 6 expands to its limit, and then the periphery 34 is linear except for the corners and easily bends, so the second sheet 6 breaks near the left end 63 and the drug 2 is pushed out of the PTP package and the PTP-packaged drug 1.

[0019] With the above-described configuration, when pushing out the drug 2, the periphery 34 of the square shape is straight and easily bendable, making it easy to push out the drug 2 from the storage section 3. Furthermore, because the drug 2 can be pushed out from the vicinity of the left end 63 of the second sheet 6, the entire second sheet 6 that covers the opening 31 does not break, and it is possible to prevent parts of the second sheet 6 from being attached to the drug 2. Furthermore, when manufacturing a resin storage sheet using compressed air molding or vacuum molding, additional processing of an existing mold is sufficient, so there is almost no increase in costs. Furthermore, since no recesses are provided, there is also no increase in costs.

[0020] (Second embodiment) The same or equivalent components and members as those in the first embodiment are designated by the same part names and the same reference numerals, and redundant explanations will be omitted where appropriate. The following description will focus on the characteristic features of the second embodiment.

[0021] A second embodiment of the present invention will be described with reference to the drawings. As shown in Figures 5, 6, 7, and 8, a PTP package and a PTP-packaged medicine 1 include a storage section 3 that protrudes from the front side and stores medicine 2 such as tablets, a first sheet 5 having a flat section 4 that surrounds the storage section 3, and a second sheet 6 that is joined to the flat section 4 on the back side and closes an opening 31 of the storage section 3. The right half 35 of the periphery of the storage section 3 in a top view is arc-shaped, and the remaining left half 34 is formed into a square shape, excluding the corners.

[0022] As shown in Figures 6 and 7, when the thumb (not shown) presses the central portion 33 of the upper surface 32 of the storage section 3 to push out the drug 2, the periphery 34 of the left half is straight except for the corners and is easily bent, so as shown in Figure 8, the force F of the thumb (not shown) moves to the left, and the force F is applied to the left side portion 62 of the central portion 61 of the second sheet 6 that blocks the opening 31 of the first sheet 5 via the drug 2.

[0023] As shown in Figure 8, when force F is applied to the left side 62 of the central portion 61 of the second sheet 6, the left side 62 of the second sheet 6 expands to its limit, and then the periphery 34 is linear except for the corners and easily bends, so the second sheet 6 breaks near the left end 63 and the drug 2 is pushed out of the PTP package and the PTP-packaged drug 1.

[0024] With the above-described configuration, when pushing out the medicine 2, the periphery 34 is linear and easily bendable except for the corners, making it easy to push out the medicine 2 from the storage section 3. Furthermore, because the medicine 2 can be pushed out from the vicinity of the left end 63 of the second sheet 6, the entire opening 31 of the second sheet 6 is not torn, and it is possible to prevent a portion of the second sheet 6 from being attached to the medicine 2. Furthermore, when stacking two PTP packages and PTP-packaged medicines 1 with the storage sections 3 facing each other, the surface area of ​​the storage section 3 on the front side is smaller than in the first embodiment, making it easier to stack them. Furthermore, when manufacturing a resin storage sheet using pressure molding or vacuum molding, additional processing of an existing mold is sufficient, resulting in almost no increase in costs. Furthermore, the absence of a recess also prevents an increase in costs.

[0025] Any modification or application is possible within the scope of the present invention. For example, the perimeter 34 of the storage unit 3 in the first embodiment, as viewed from above, may be formed into a regular hexagon or regular octagon, excluding the corners. Furthermore, the perimeter 35 of the right half of the storage unit 3 in the second embodiment, as viewed from above, may be arc-shaped, and the perimeter 34 of the remaining left half may be formed into a half regular hexagon or regular octagon, excluding the corners. Furthermore, the orientation of the storage unit 3 may be changed by 90 degrees from that of the second embodiment so that the center 61 of the storage unit 3 can be pushed out with the right or left thumb from the lateral direction of the PTP package and the PTP-packaged medicine 1.
