This application is a national stage application of International Patent Application No. PCT/JP2019/030148, filed Aug. 7, 2019, which claims priority to Japanese Patent Application No. 2018-153416, filed Aug. 17, 2018. The entirety of the aforementioned applications is incorporated herein by reference.
The present invention relates to a packaging body, a tablet-containing packaging body, a method for manufacturing an accommodation member of a packaging body, and an apparatus for manufacturing an accommodation member of a packaging body.
To date, orally disintegrating tablets (as disclosed, for example, in Patent Document 1) and easy-to-take solid formulations (as disclosed, for example, in Patent Document 2) have been developed as highly convenient dosage forms that can be safely taken by elderly people, children, patients who have difficulty swallowing medication, and the like, and that can be easily taken without water. For example, in a case where a particular patient is unable to recognize the need of taking medicine and expectorates a tablet, a tablet that disintegrates within the oral cavity, for example, within 10 seconds (a very rapidly disintegrating tablet), as disclosed in Patent Document 1, is necessary.
The very rapidly disintegrating tablets are formed, for example, as thin tablets. Examples of thin tablets include truly flat tablets having a thin cylindrical shape with a diameter of approximately 14 mm or greater and a thickness of 0.5 mm or greater and 1.5 mm or less. Although the thin tablets are used, for example, as very rapidly disintegrating tablets, some of them are used in other applications.
Known thick tablets are provided, for example, in containers called blister packs. A blister pack is formed, for example, by combining a plastic accommodation sheet and an aluminum cover. In the accommodation sheet, an accommodation portion is formed as a columnar deep recess fitted to the tablet. An inlet of the accommodation portion is covered with a cover in a state in which the tablet is placed in the accommodation portion. The cover is in close contact with the accommodation sheet around the accommodation portion. When the tablet is taken out, the tablet is pushed toward the cover from the outside of the accommodation portion, for example, to tear the cover with the tablet.
In one example, the inlet of the accommodation portion is covered with a cover that slides parallel with an opening of the accommodation portion.
In the case of a known thick tablet, it is easy to push the tablet to tear the cover. However, in the case of a thin tablet, a thin tablet that has undergone a strong force toward the cover breaks. In addition, there is a problem that, when the accommodation portion is tilted to take out the thin tablet, the thin tablet can be easily dropped. In addition, fingers need to be inserted into the accommodation portion to pinch the thin tablet across a long width, and thus there is a problem that the thin tablet is likely to be broken.
An object of the present invention is to provide a packaging body that is not liable to damage a thin tablet in comparison with the related art, a tablet-containing packaging body that is not liable to damage a thin tablet, a method for manufacturing an accommodation member of a packaging body that is not liable to damage a thin tablet, and an apparatus for manufacturing an accommodation member of a packaging body that is not liable to damage a thin tablet.
More specifically, the present invention provides the following aspects.
A packaging body for containing a thin tablet, the packaging body including an accommodation member,
The packaging body according to the first aspect, wherein the structure, in which the at least a portion of the thin tablet accommodated in the accommodation portion moves toward the inlet upon application of the force, includes a structure in which an other portion of the thin tablet accommodated in the accommodation portion protrudes from the inlet upon application of the force.

(Orally Disintegrating Tablet)
The thin tablet 100 is an orally disintegrating tablet in one example. The thin tablet 100 has a disintegration time in water of approximately 7 seconds or less, and preferably 5 seconds or less in one example. The thin tablet 100 has an oral disintegration time of 6 seconds or less, preferably 5 seconds or less in one example.
The medicinal ingredient contained in the thin tablet 100 is a pharmaceutical ingredient or a nutritional component in foods and health foods. The medicinal ingredient may be added alone, or may be coated or granulated for the purpose of slow release, bitterness masking or the like. Note that the application, type and the like of the medicinal ingredient contained in the thin tablet 100 are not particularly limited.
In addition to the medicinal ingredient, the thin tablet 100 can contain, as necessary, other optional pharmaceutically acceptable ingredients such as excipients, surfactants, lubricants, acidulants, sweeteners, flavoring agents, spices, colorants, and stabilizers. As these optional ingredients, for example, the ingredients described in the Japanese Pharmaceutical Excipients Dictionary (Yakuji Nippo, Ltd.) and the Japanese Pharmacopeia can be used. Furthermore, as long as the desired effect of the present invention is achieved, the blending proportions of the respective ingredients are not particularly limited, and can be determined, as appropriate, by a person skilled in the art.
A material 170 for the thin tablet 100 described above (
The disintegrable particle composition contains, for example, an acid type carboxymethyl cellulose as a disintegrant component. Various optional components known to those skilled in the art may be appropriately added to and mixed with the disintegrable particle composition, for example, for the purpose of adjusting various characteristics such as disintegration force, binding force, and feeling of taking tablet. Examples of such ingredients can include fluidizers, sweeteners, spices, and colorants.
The amount of each of the components blended in the disintegrable particle composition can be determined, as appropriate, by a person skilled in the art depending on the type of each of the components, the type and application of the medicinal ingredient to be used in the disintegrable particle composition, the application of the orally disintegrating tablet that is the final product, and the like.
(Easy-to-Take Solid Formulation)
The thin tablet 100 is an easy-to-take solid formulation in addition to or instead of being an orally disintegrating tablet. “Easy-to-take” generally means that, as a property or characteristic of a solid formulation or the like, the solid formulation is easy to drink (easy to swallow). In one example, the thin tablet 100 includes a gelling agent that exhibits slipperiness when touched with water.
(Modified Example of Thin Tablet)
In other examples, the angle between the surface and the side surface is less than 90 degrees. In such other examples, the second surface is concentric with the first surface, and, further, is a circle with a radius smaller than that of the first surface, for example. In other words, it is frustoconical.

As illustrated in
The accommodation member 142 is formed by processing a thin sheet material. The accommodation member 142 includes a margin 145 that extends parallel to the xy plane, and an accommodation portion 146 recessed in the z2 direction from the margin 145. The accommodation portion 146 includes a sliding surface 148 for sliding the thin tablet 100 within the accommodation portion 146.
The accommodation member 142 includes an inlet 147 defining a boundary between the margin 145 and the accommodation portion 146 at the outer edge. The inlet 147 is open in the z1 direction. The accommodation portion 146 is recessed from the inlet 147 in the z2 direction. As illustrated in
The sliding surface 148 is rotationally symmetric about an imaginary central axis 151 orthogonal to the imaginary plane 150. The imaginary central axis 151 passes through the center of the inlet 147. The sliding surface 148 extends continuously from the inlet 147 to a position where it intersects the imaginary central axis 151 within the accommodation portion 146. In one example, the sliding surface 148 has a shape obtained by cutting one spherical surface in the imaginary plane 150.
The inclination angle of the sliding surface 148 with respect to the imaginary plane 150 is not less than 0 degrees and not greater than 70 degrees at any position. The inclination angle of the sliding surface 148 in a region closest to the inlet 147 is greater than 0 degrees. The inclination angle is preferably not less than 0 degrees and not greater than 45 degrees, and more preferably not less than 0 degrees and not greater than 30 degrees, because the thin tablet 100 easily slides upon application of a force in a direction orthogonal to the z direction. The inclination angle of the sliding surface 148 with respect to the imaginary plane 150 decreases as the distance from the inlet 147 increases. The inclination angle changes gently as the distance from the inlet 147 increases. For example, in the cutting plane illustrated in

(Material)
Examples of the material for the sheet material 168 (
Examples of the material for the cover 143 includes the materials, described above, for forming the accommodation member 142.
Examples of the material for the adhesive layer 144 include resins. The resin that forms the adhesive layer 144 contains an antioxidant as necessary. Examples of the resin for forming the adhesive layer 144 include polyolefin, ethylene-methacrylate-glycidyl acrylate ternary copolymers; and materials obtained by grafting monobasic unsaturated fatty acids, dibasic unsaturated fatty acids, or their anhydrides onto various polyolefins (such as maleic acid-grafted ethylene-vinyl acetate copolymers and maleic acid-grafted ethylene-α-olefin copolymers). Examples of monobasic unsaturated fatty acids include acrylic acid and methacrylic acid. Examples of dibasic unsaturated fatty acids include maleic acid, fumaric acid, and itaconic acid. Examples of antioxidants include known antioxidants such as hindered phenol-based antioxidants, phosphorous-based antioxidants, and thioether antioxidants. The thickness of the adhesive layer 144 is not particularly limited, but is preferably not less than 3 μm and not greater than 50 μm, and more preferably not less than 5 μm and not greater than 30 μm.
In one example, the accommodation member 142 is formed from a material obtained by coating aluminum with polypropylene, and a polyolefin is used as the cover 143. The accommodation member 142 and the cover 143 are thermally cured (heat sealed) via the adhesive layer 144. In the other embodiments described herein, the same manufacturing apparatus and the same materials are used except for the shape of the mold, and a tablet-containing packaging body is manufactured by the same manufacturing method.
(Modified Example of Packaging Member)
In other examples, a region that is not the sliding surface 148 is included between the sliding surface 148 and the inlet 147. It is preferred that the sliding surface 148 and the inlet 147 be continuous for the purpose of moving the thin tablet 100 smoothly from the sliding surface 148 through the inlet 147 to the outside. In other examples, the inclination angle of the sliding surface 148 with respect to the imaginary plane 150 may be constant. In other examples, the cover 143 at least partially covers the inlet 147. That is, the cover 143 entirely or partially covers the inlet 147.
(Modified Example of Thin Tablet)
The thin tablet 100 may not include the protrusions 120 illustrated in
The outer edge 113 of the body 110 and the protrusion 120 may be different in contour, when viewed from the z-direction. When viewed from the z-direction, the outer edge 113 may be polygonal. The corners of the polygonal outer edge 113 may be rounded. The outer edge 113 may have any other shape. The shape of the outer edge 113 may be a complex shape such as a flower shape or a fish shape. The body 110 may be frustoconical, frustopyramidal, or otherwise frustoconical.
(Summary 1)
According to the present embodiment, the thin tablet 100 is easily taken out of the packaging body 141 because at least a portion of the thin tablet 100 moves toward the inlet 147 upon application of a force to a portion of the thin tablet 100 with an object such as a finger.
According to the present embodiment, the thin tablet 100 is easily taken out of the packaging body 141 because an other portion of the thin tablet 100 protrudes from the inlet 147 upon application of the force to the portion of the thin tablet 100 with the object such as a finger.
According to the present embodiment, the sliding surface 148 does not overlap with any other portion of the accommodation portion 146 in a direction orthogonal to the imaginary plane 150, and, further, the sliding surface 148 is inclined with respect to the imaginary plane 150. So, an other portion of the thin tablet 100 can be easily protruded from the inlet 147 by moving the thin tablet 100 along the sliding surface 148.
According to the present embodiment, the inclination angle of the sliding surface 148 with respect to the imaginary plane 150 is not less than 0 degrees and not greater than 70 degrees, and the inclination angle of the sliding surface 148 in the region closest to the inlet 147 is greater than 0 degrees. So, it is easy to apply a force to the thin tablet 100 in a direction parallel to the imaginary plane 150, and an other portion of the thin tablet 100 can be easily protruded from the inlet 147.
According to the present embodiment, the inclination angle of the sliding surface 148 with respect to the imaginary plane 150 decreases as the distance from the inlet 147 increases. As a result, movement in a direction orthogonal to the imaginary plane 150 is reduced while movement in a direction parallel to the imaginary plane 150 is increased. So, the thin tablet 100 can be moved smoothly.
According to the present embodiment, the cover 143 that at least partially covers the inlet 147 makes it possible to accommodate the thin tablet 100 stably in the accommodation portion 146.
According to the present embodiment, because the packaging body 141 includes the adhesive layer 144 that releasably adheres the cover 143 to the margin 145, it is not necessary to tear open the cover 143, making it difficult to break the thin tablet 100.
According to the present embodiment, when the thin tablet 100 is positioned within the accommodation portion 146 with the outer edge 113 of the second surface 111-2 in contact with the sliding surface 148, the protrusion 120 provided on the first surface 111-1 faces the cover 143. So, the thin tablet 100 is less likely to move in the accommodation portion 146 and less likely to be damaged in comparison with the case when the protrusion 120 is absent. Further, because the protrusion 120 faces the cover 143, rocking of the thin tablet 100 can be restricted without thickening the body 110, making it difficult to damage the thin tablet 100.
According to the present embodiment, the inlet 147 is a circle parallel to the imaginary plane 150 and the sliding surface 148 is rotationally symmetric about the imaginary central axis 151 orthogonal to the imaginary plane 150. So, the thin tablet 100 is less likely to be damaged even when the thin tablet 100 is moved in any direction. Further, the imaginary central axis 151 passes through the center of the inlet 147 and the sliding surface 148 extends continuously from the inlet 147 to a position where it intersects the imaginary central axis 151 within the accommodation portion 146. So, the thin tablet 100 is easily moved smoothly to the position where the sliding surface 148 intersects the imaginary central axis 151.
(Summary 2)
According to the present embodiment, the protrusion 120 is provided on the surface 111. So, when the thin tablet 100 is placed on the external plane 130 (e.g., a floor), the gap 135 is formed between the outer edge 113 of the surface 111 and the external plane 130, and the thin tablet 100 is thus easy to take.
According to the present embodiment, in the case where the angle formed by the surface 111 and the side surface 112 is 90 degrees or less, if the protrusion 120 is absent, the thin tablet 100 is particularly difficult to take. However, by virtue of the protrusion 120, the gap 135 is formed between the outer edge 113 of the surface 111 and the external plane 130, and the thin tablet 100 is thus easy to take.
According to the present embodiment, the thickness of the body 110 is 0.5 mm or greater and 1.5 mm or less, or 0.5 mm or greater and 1.2 mm or less. So, the gap 135 is formed between the surface 111 and the external plane 130 in the thin tablet 100 which is difficult to pinch, thereby making it possible to easily take the thin tablet 100.
According to the present embodiment, in the thin tablet 100 that is difficult to pinch because the maximum width of the surface 111 is 14 mm or greater, the gap 135 is formed between the surface 111 and the external plane 130, thereby making it easy to take the thin tablet 100.
According to the present embodiment, the area proportion of the protrusion 120 to the surface 111 is 90% or less, and thus it is possible to easily take the thin tablet 100 while preventing the thin tablet 100 from becoming thicker than necessary by virtue of the protrusion 120.
According to the present embodiment, the height of the protrusion 120 from the surface 111 is 100% or less of the thickness of the body 110, and thus it is possible to easily take the thin tablet 100 while preventing the thin tablet 100 from becoming thicker than necessary by virtue of the protrusion 120.
According to the present embodiment, the gap 135 of 0.1 mm or greater is formed between at least a portion of the outer edge 113 and the external plane 130, and thus the thin tablet 100 is easily taken with a person's finger.
According to the present embodiment, the protrusion 120 overlaps with the center of gravity of the body 110, and thus the body 110 is easily tilted about the protrusion 120 in a variety of orientations.
According to the present embodiment, the protrusion 120 is provided on each of the two surfaces 111. So, even when any surface 111 faces the external plane 130, the gap 135 can be formed between the surface 111 and the external plane 130, and the thin tablet 100 is easy to take.
According to the present embodiment, when the thin tablet 100 is at least either an orally disintegrating tablet or an easy-to-take solid formulation, it is possible to quickly take out and pick up the thin tablet 100 by virtue of the presence of the gap 135. So, it is easy to prevent the thin tablet 100 from disintegrating and gelling while it is being picked up.
According to the present embodiment, the protrusions 120 make the thin tablet 100 both difficult to move within the packaging body 141 and easy to pick up, and thus the structure is simpler in comparison with the case when separate mechanisms are provided.
The accommodation member 242 includes a first barb 252-1 and a second barb 252-2 (hereinafter sometimes referred to as the barb 252 without distinction). The first barb 252-1 extends in the z1 direction from the end edge on the y1 side of a margin 245 and then extends in the y2 direction. Since the cover 243 is sandwiched between the margin 245 and the first barb 252-1, it does not move substantially in the z-direction (at least to such an extent that a thin tablet 200 moves outside from an inlet 247). Also, the cover 243 does not move substantially in the y1 direction because it is blocked by the first barb 252-1. The second barb 252-2 extends in the z1 direction from the end edge on the y2 side of a margin 245 and then extends in the y1 direction. Since the cover 243 is sandwiched between the margin 245 and the second barb 252-2, it does not move substantially in the z-direction. Also, the cover 243 does not move substantially in the y2 direction because it is blocked by the second barb 252-2.
The cover 243 only moves in the x-direction along the barbs 252. When opening the packaging body, the user shifts the cover 243 in the x-direction, and thus the cover 243 and the accommodation member 242 are separated from each other. As a result, the thin tablet 200 is exposed to the outside. In other examples, the cover 243 may be slidable relative to the accommodation member 242 such that the inlet 247 can be opened and closed.
According to the present embodiment, the thin tablet 200 is exposed to the outside simply by sliding the cover 243, and thus the thin tablet 200 is less likely to break in comparison with the case when the cover 243 is torn with the thin tablet 200.
The accommodation member 342 is formed by processing a thin sheet material. As illustrated in
The accommodation member 342 includes an inlet 347 defining a boundary between the margin 345 and the accommodation portion 346 at the outer edge. The inlet 347 is open in the z1 direction. The accommodation portion 346 is recessed from the inlet 347 in the z2 direction. As illustrated in
The accommodation portion 346 includes a tubular wall 353 extending in the z2 direction from an outer edge of the inlet 347 to an outer edge of the sliding surface 348. The inlet 347 extends parallel to the xy plane (i.e., parallel to the same imaginary plane as in
The sliding surface 348 is a plane that is inclined with respect to the xy plane. That is, the inclination angle of the sliding surface 348 with respect to the xy plane is constant. The inclination angle is greater than 0 degrees and not greater than 30 degrees. In the z-direction, the distance between the end edge on the y1 side of the sliding surface 348 and the inlet 347 is greater than the distance between the end edge on the y2 side of the sliding surface 348 and the inlet 347. The sliding surface 348 extends parallel to the x-direction in the same cross section as in
The cover 343 is formed of a single continuous sheet material parallel to the xy plane and is positioned on the z2 side of the accommodation member 342. The cover 343 generally covers the entirety of the inlet 347 without slack and covers the margin 345. The adhesive layer 344 extending parallel to the xy plane is sandwiched between the cover 343 and the margin 345 in the z-direction. The adhesive layer 344 releasably adheres the cover 343 to the margin 345. The cover 343 includes a handle 349 on a portion of the outer edge. There is no adhesive layer 344 between the handle 349 and the margin 345.

According to the present embodiment, the inclination angle of the sliding surface 348 is constant, and thus the thin tablet 100 can be moved smoothly with a constant force.
According to the present embodiment, when a thin tablet 400 moves along the sliding surface 448 in the y2 direction, the thin tablet 400 smoothly goes out from the inlet 447 without hitting a wall 453. Therefore, the thin tablet 400 is less likely to break when taken out. Also, in other examples where no second protrusion 420-2 is provided, the thin tablet 400 is easily moved outside from the inlet 447.

Note that a mold, which is opposite in concave/convex shape to the mold 580, may be used. The mold 580 is provided with a plurality of suction holes 587 in at least one of the first molding surface 581 to the sixth molding surface 586. The suction holes 587 may be provided elsewhere.
In other examples, the groove 571 is recessed from at least a portion of the outer edge 574 of the opposing surface 572.
(Summary 1)
According to the present embodiment, the thin tablet 500 is easily taken out of the packaging body 541 because at least a portion of the thin tablet 500 moves toward the inlet 547 upon application of a force to a portion of the thin tablet 500 with an object such as a finger.
According to the present embodiment, the thin tablet 500 is easily taken out of the packaging body 541 because an other portion of the thin tablet 500 protrudes from the inlet 547 upon application of the force to the portion of the thin tablet 500 with the object such as a finger.
According to the present embodiment, the accommodation portion 546 includes the loading table 570 suitable for loading the thin tablet 500 and the groove 571 recessed toward a direction away from the inlet 547, within the accommodation portion 546. Further, the loading table 570 includes the opposing surface 572 facing the inlet 547, and the groove 571 is recessed from at least a portion of the outer edge 513 of the opposing surface 572. So, the thin tablet 500 is tilted at the boundary between the opposing surface 572 of the loading table 570 and the groove 571, and thus an other portion of the thin tablet 500 can be easily protruded from the inlet 547.
According to the present embodiment, the groove 571 is recessed from the entirety of the outer edge 513 of the opposing surface 572, so the thin tablet 500 can be tilted at various positions on the boundary between the opposing surface 572 and the groove 571.
According to the present embodiment, the cover 543 that at least partially covers the inlet 547 makes it possible to accommodate the thin tablet 500 stably in the accommodation portion 546.
According to the present embodiment, because the packaging body 541 includes the adhesive layer 544 that releasably adheres the cover 543 to the margin 545, it is not necessary to tear open the cover 543, making it difficult to break the thin tablet 500.
According to the present embodiment, a portion of the thin tablet 500 is positioned between the inlet 547 and the groove 571. So, the thin tablet 500 is easy to tilt at the boundary between the opposing surface 572 of the loading table 570 and the groove 571, and an other portion of the thin tablet 500 can be easily protruded from the inlet 547. Further, because the protrusion 520 faces the cover 543 in the loading state, rocking of the thin tablet 500 can be restricted without thickening the body 510, making it difficult to damage the thin tablet 500.
According to the present embodiment, the protrusion 520 is received in the receiving hole 573, thereby making it possible to restrict rocking of the thin tablet 500.
The diameter of the inner edge 675 of the opposing surface 672 parallel to the xy plane is larger than the maximum diameter of a second protrusion 620-2 parallel to the xy plane (i.e., the diameter of a boundary with the second surface 611-2). With the entirety of the second protrusion 620-2 in a receiving hole 673, the opposing surface 672 is brought into contact with the second surface 611-2, and the entirety of the inner surface of the receiving hole 673 is spaced apart from the second protrusion 620-2. The inner surface of the receiving hole 673 may be brought into contact with the second protrusion 620-2.
According to the present embodiment, the thin tablet 600 is stable due to contact between the planar opposing surface 672 and the planar second surface 611-2.
The above embodiments and modified examples can be combined as long as the technical ideas disclosed herein are realized.
