Description

TECHNICAL FIELD The present invention relates to a press-through pack package for storing a tablet-shaped food product, a capsule, and a tablet drug (hereinafter referred to as a tablet or the like). More specifically, the present invention relates to a press-through pack package that can be taken out with a small force when taking out the tablets and the like packaged in the package, and the taken-out tablets and the like do not scatter.

A conventional press-through pack package (hereinafter abbreviated as PTP) is composed of a lid member made of an aluminum foil and a heat seal layer, and a molded sheet having a pocket portion formed therein. The back surface of the convex portion (as viewed from the outside) of the pocket portion in which the tablets and the like are stored is pushed with fingers to break the lid material, and the tablets and the like are taken out, and then taken.
However, for patients, elderly people, infants, and other persons with weak finger strength, there is a problem that the tablet or the like is insufficient in pushing force and it is difficult to take out the drug from the PTP. In addition, the extruded tablets and the like roll out vigorously and are scattered.

The following techniques have been proposed for the purpose of solving the above problems.

In Patent Document 1, when the molded sheet and the lid member are joined, a region extending from a pocket portion, which is a recess for storing tablets of the molded sheet, to a flange portion, which is a region other than the pocket portion, On the other hand, a score line is provided in the region of the lid member facing the cut line. The position of the pocket portion of the lid member and the position of the cut line are not particularly aligned.

In Patent Document 2, an easy-opening process is performed by forming fine recesses or fine holes in a polyester film forming a layer of a lid material.

Patent Document 3 proposes a technique in which a plastic film forming a layer of a lid material is provided with a cut line in one of the pocket portions of the lid material by a laser beam.

According to Patent Documents 1 to 3, tablets and the like can be easily taken out from the PTP.

Japanese Patent No. 5133350 JP, 2002-178450, A Noboru No. 2583616

However, in the invention of Patent Document 1 described above, since the positions of the pocket portion and the score line are not specified and are random, the force required for taking out the tablets or the like is different for each production lot of PTP or for one lot. It is difficult to stabilize each pocket in the PTP.

Further, in the invention of Patent Document 2 described above, an easy opening process is performed by forming fine recesses or fine holes in the region of the pocket portion of the lid material of the polyester film forming the layer of the lid material. Although the force required for taking out etc. is reduced, it is not sufficiently reduced as compared with making a score line.

Further, in the invention of Patent Document 3, since the score line is present only in one of the pocket portions of the lid material, it is necessary to press at a specific position when taking out the tablet or the like, Further, the position of the score line is not disclosed.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and when the tablets and the like are taken out from the PTP, the force of the fingers required is small, and in addition, the force of taking out the tablets and the like is required. Since it is stable, an excessive extrusion force is not necessary, and it is an object of the present invention to provide a PTP in which tablets and the like roll out vigorously and do not dissipate.

The press-through pack package of the present invention,
At least a plastic film, aluminum foil, a lid material in which an adhesive layer is laminated in this order,
A molded sheet having a flange portion joined to the lid material via an adhesive layer of the lid material, and a pocket portion,
The plastic film includes an easy-opening portion at least in a region corresponding to the pocket portion,
The easy-opening portion is characterized in that a cut line is provided.

According to the above means, when the tablet or the like is taken out from the PTP, the easy-opening portion and the score line for reducing the taking-out force are present in the pocket portion of the lid material, and the force for taking out the tablet or the like is reduced, and Be stable.
Further, since the score line exists only in the plastic film of the lid material and the aluminum foil is not scratched, the gas barrier property, the light shielding property and the like can be maintained.

According to the present invention, when a tablet or the like is taken out from the PTP, a small hand force is required, so that even a person with weak hand force such as a patient, an elderly person or an infant can easily take out the tablet or the like. Moreover, since the force for taking out the tablet or the like is stable, an excessive pushing force is unnecessary, and the tablet or the like rolls out vigorously to provide a PTP that does not scatter.

It is explanatory drawing of embodiment of the notch line of the press through pack package of a prior art.

Hereinafter, the present invention will be described with reference to the drawings. However, the present invention is not limited to these concretely exemplified forms and various concretely described structures.
In addition, in each drawing, the size and ratio of members may be changed or exaggerated for easy understanding. Further, for ease of viewing, unnecessary portions and repeated reference numerals may be omitted.

FIG. 1 is a perspective view of a PTP 1 according to an embodiment of the present invention as viewed from the lid member 10 side. 2 is a sectional view taken along the line AA of FIG. 1 and 2, the PTP 1 is formed by adhering a lid member 10 and a molding sheet 11, and tablets 15 and the like not shown in FIG. 1 are stored in a pocket portion 21 of the molding sheet 11. ing.

The flange portion 22, which is a flat portion in the molded sheet 11, is a portion that abuts and is bonded to the lid member 10.

At a position corresponding to the pocket portion 21 of the molded sheet 11, a pocket portion 31 of the lid member 10 having the same shape as the pocket portion 21 and being non-adhesive is formed. The pocket portion 31 of the lid member 10 is smooth and corresponds to the pocket portion 21 of the molded sheet 11. Since the periphery of the pocket portion 31 of the lid member 10 is normally bonded to the flange portion 22 of the molded sheet 11 with a concavo-convex pattern by press working in order to enhance the bonding strength, A concave-convex pattern is provided to make the pocket portion 31 of the lid member 10 stand out. The area around the pocket portion 31 of the lid member 10 is referred to as a flange portion 32 of the lid member 10. When viewed two-dimensionally, the pocket portion 31 of the lid member 10 and the pocket portion 21 of the molded sheet 11 substantially overlap each other.

In FIG. 1, five pocket portions 21 are arranged along the longitudinal direction of the PTP and two pocket portions 21 are arranged in the lateral direction.

Perforations 26 that penetrate the lid member 10 and the flange portion 22 of the molded sheet 11 are provided in the lateral direction so that the tablets can be easily separated into two tablets. However, in recent years, in order to prevent accidental ingestion of subdivided PTPs, perforations 26 may not be provided.

Further, an ear portion 27 may be provided on one side of the peripheral portion of the PTP 1 so that the name of the medicine, the model name, the lot number, etc. can be written.

The layer structure of the lid member 10 will be described with reference to FIG. The lid member 10 includes a plastic film 14, an aluminum foil 13, and an adhesive layer 12. The plastic film 14 and the aluminum foil 13 are bonded with an adhesive agent (not shown). The plastic film 14 is provided with a score line 16 for facilitating the opening.

Next, the PTP 1 will be described in detail for each component.

(Plastic film for lid material)
The plastic film 14 used for the lid member 10 of the PTP 1 of the present invention is preferably a plastic film having a thickness of 6 to 50 μm. It is more preferable to use a plastic film having a thickness of 6 to 25 μm. If the thickness is less than 6 μm, the strength is not sufficient, and there is a possibility that the PTP1 may break during transportation or storage. On the other hand, if it exceeds 50 μm, the strength becomes unnecessarily high, which may impair the easy-open property of tablets and the like. Therefore, if the thickness of the plastic film 14 is in the range of 6 to 50 μm, it is possible to have both easy-open property and strength. The type of the plastic film 14 is not particularly limited, but a polyethylene film, a polypropylene film, a polyester film, a polyamide (nylon) film, a (meth)acrylic resin, a polyvinyl chloride resin, a polystyrene resin. Films of polyvinylidene chloride resin, saponified ethylene-vinyl acetate copolymer, polyvinyl alcohol, polycarbonate resin, polyvinyl acetate resin, acetal resin, and other various resins can be used. These plastic films may be uniaxially or biaxially stretched or unstretched.

(Easy opening section)
The easy opening section will be described. The easy-open portion 33 is present only in the plastic film 14, and a plurality of microfabrications are spread in a plane. The easy-open portion 33 is composed of a fine recess or a fine hole. Only the fine recesses or only the fine holes may be present, or the fine recesses and the fine holes may coexist. The fine recess has an opening on the outer surface of the plastic film 14 (opposite surface to be joined to the aluminum foil), but does not penetrate therethrough. When the opening has a substantially circular shape, its diameter is about 0.3 to 1.5 mm. When the opening is not substantially circular, the area of the opening is substantially the same as in the case of the substantially circular shape. Further, the opening may be linear, and in that case as well, it does not penetrate.
Since the fine recesses do not penetrate, when the plastic film 14 and the aluminum foil 13 are bonded with an adhesive, the adhesive does not seep out to the outer surface side of the plastic film 14.

When the fine holes penetrate the plastic film 14 and the opening has a substantially circular shape, the diameter thereof is about 0.1 to 1 mm. When the opening is not substantially circular, the area of the opening is substantially the same as in the case of the substantially circular shape. Further, the opening may be linear, and in that case as well, it penetrates.
Since the fine holes penetrate the plastic film 14 and cut the entire thickness of the plastic film 14 without stopping the hole forming operation in the middle of the thickness of the plastic film 14, precise management of the depth of hole forming is unnecessary. Therefore, the processing speed can be increased.

The easy-open portion 33 is at least in the region of the pocket portion 31 of the plastic film 14. In the example shown in FIG. 2, the pocket portion 31 and the easy-opening portion 33 are substantially the same area, but the easy-opening portion 33 may exist beyond the area of the pocket portion 31, It may exist on the entire surface.
Further, the easy-open portion 33 may be smaller than the area of the pocket portion 31 inside the region of the pocket portion 31, but a part or all of the score line 16 corresponds to the easy-open portion. It is desirable to overlap the area.

(Cut line)
FIG. 3 is a plan view of the pocket portion 31 of the lid member 10. A cut line 16 is shown in FIGS. 1, 2 and 3, and the cut line 16 will be described below.
The cut line 16 is provided only on the plastic film 14 and does not extend to the aluminum foil 13. The score line 16 may be processed into the plastic film 14 before the lid material 10 is laminated, and then laminated. The method of inserting the score line 16 is not particularly limited, but it is possible to use a known punching method such as a Thomson punching method, a rotary die cutting method, a CAD cutting method, a laser cutting method. The extraction method is appropriately selected in consideration of the production quantity, production speed, quality requirement, cost and the like.

The cut line 16 may be provided after the lid material 10 is laminated. In this case, when aluminum foil is laminated, laser processing is preferably used as a processing method. In particular, the carbon dioxide laser is absorbed by the plastic film 14 to generate heat, and the plastic film 14 is melted by heat, whereas the carbon dioxide laser is not absorbed by the aluminum foil 13. The aluminum foil 13 is not blown. Therefore, if the carbon dioxide laser is irradiated from the plastic film 14 side of the lid member 10, only the plastic film 14 can be cut.

The processing position of the score line 16 will be described.
FIG. 4A shows a processing region of the cut line 16 in the case of a circular pocket.
The cut line 16 is provided in the region of the pocket portion 31 of the lid member 10. More preferably, the score line 16 is processed only in the processing region 25, which is a region where the distance from the center point 24 of the pocket portion 31 to the outer peripheral portion 23 of the pocket portion 31 is short. That is, it is processed not in the vicinity of the center point 24 of the pocket portion 31 of the lid member 10 but in a region near the outer peripheral portion 23.

When taking out the tablet 15 or the like, the convex portion on the outer side of the molded sheet 11 is pushed, but the pressing force is transmitted to the lid member 10 via the tablet 15 or the like. At this time, when the corners of the outer periphery of the tablet etc. 15 (including the case of having a curved surface in a chamfered shape) come into contact with the plastic film 14 in a narrow area, a strong pressure is applied. The plastic film 14 is easily broken. If the score line 16 exists at that position, the PTP 1 can be opened with a smaller force.

Since the outer peripheral portion of the tablet or the like 15 is close to the outer peripheral portion 23 of the pocket portion of the lid member 10, it is desirable to process the score line 16 in the processing region 25 of the score line 16 as described above.
Further, it is sufficient that the score line 16 extends over at least a part of the region of the easy-open section, and more preferably the entire score line 16 exists in the easy-open section.

FIG. 4B shows a processing region 25 of the cut line 16 in the case of a rectangular pocket whose corners are arcs. Similar to the case of the circular pocket described above, in the pocket portion 31 of the lid member 10, only in the processing region 25 which is a region where the distance from the center point 24 of the pocket portion 31 to the outer peripheral portion 23 of the pocket portion 31 is short. Then, the score line 16 is processed. That is, it is processed not in the vicinity of the center point 24 of the pocket portion 31 of the lid member 10 but in a region near the outer peripheral portion 23. The action and effect are the same as in the case of the circular pocket, so the explanation is omitted.

The direction in which the score line 16 is arranged will be described.
Of the angle θ formed by the cut line 16 and the line connecting the center point 24 of the pocket 31 and the center point 17 of the cut line 16, the smaller angle θ is preferably 45° or more. The smaller angle is an acute angle (including a right angle) when two straight lines intersect. That is, it is desirable that the above two straight lines intersect at an angle as close to orthogonal as possible. This is because the breakage of the lid material 10 at the time of opening is easy to break in the direction orthogonal to the straight line passing through the center point 24 of the pocket portion 31.

When the score line 16 is a curve, it is read as an angle θ formed by a tangent line at the center point 17 of the score line 16 and a straight line connecting the center point 17 of the score line 16 and the center point 24 of the pocket portion 31. ..
When the score line 16 is bent at the center point 17, two lines that are divided at the center point 17 and a straight line that connects the center point 17 of the score line 16 and the center point 24 of the pocket portion 31 are formed. Of the respective angles θ formed, the smaller angle θ may be 45° or more.
When the cut line 16 is a discontinuous curve at the center point 17, it is read as the angle θ formed by the tangent line of the center point 17 of the cut line 16 and the straight line passing through the center point 24 of the pocket portion 31.

The arrangement when there are a plurality of cut lines 16 will be described.
When there are a plurality of scoring lines 16, the shortest distance between one scoring line and another adjacent scoring line is longer than the longer length of the two scoring lines 16.
If the adjacent score lines 16 are close to each other, the lid member 10 will be rapidly broken when the tablets 15 or the like are taken out, whereby the resistance of the PTP 1 against the pressing with the fingers is sharply reduced. At this time, excessive pressing force is applied to the convex portion (as viewed from the outside) of the molded sheet 11, and the force is also applied to the tablets 15 and the tablets 15 may roll out and be scattered.
With the arrangement as in the present invention, it is possible to prevent the lid member 10 from being abruptly broken, and prevent the tablets 15 and the like from rolling out and scattering.

(Aluminum foil)
The aluminum foil 13 of the lid member 10 of the PTP 1 of the present invention is often used from the viewpoint of low cost, gas barrier property, easy opening property and the like.
As the aluminum foil 13 used for the lid member 10 of the PTP 1 of the present invention, a hard material such as JIS H4160 alloy No. 1N30 material, 8021 material, 8079 material having a thickness of about 6 to 30 μm can be adopted. Further, an aluminum foil other than the aluminum foil specified by JIS or the like, for example, an Al-Mn-based aluminum alloy foil can also be used. The method for laminating the aluminum foil 13 and the plastic film 14 is not particularly limited, but an extrusion laminating method or a dry laminating method can be used.

(Adhesive layer)
The adhesive layer 12 used for the lid member 10 of the PTP 1 of the present invention is heat-sealed (ultrasonic heat seal, high frequency heat seal, electric heater head heat seal, etc.) to the flange portion 22 which is the outer peripheral portion of the pocket portion 21 of the molded sheet 11. It is possible to use a polyolefin-based (polyethylene-based or polypropylene-based) thermo-adhesive resin capable of including a known heating method), or a non-stretched or stretched film thereof.
Further, a heat seal lacquer may be applied to the aluminum foil 13 by a known method such as gravure printing.

(The surface of the lid material)
The outer surface of the lid member 10 of the PTP 1 of the present invention may be printed or colored, and may be laminated with an OP (overprint) layer, a primer layer, an anchor coat layer, etc., if necessary, and antifogging. The surface of any layer may be coated with an agent, a lubricant, an anti-slip agent, and various coating agents. Further, paper, synthetic paper, etc. may be laminated within a range that does not impair the effects of the present invention. The method for laminating each layer is not limited to the above, and a known method can be adopted.

(Layer composition of lid material)
In the completed form of PTP1, from the outside of the lid member 10,
[Outside] Plastic film 14/Aluminum foil 13/Adhesive layer 12 [Molding sheet side]
Will be configured.
Polyethylene terephthalate (hereinafter sometimes abbreviated as PET) is often used for the plastic film 14 in terms of cost and performance.
The plastic film 14 and the aluminum foil 13 are joined by a dry laminating method. Alternatively, an extrusion method may be used in which a molten thermoplastic resin such as a polyethylene resin is extruded and joined between the plastic film 14 and the aluminum foil 13.

The adhesive layer 12 may be formed by applying a heat seal lacquer to the aluminum foil 13. Further, the aluminum foil 13 and the sealant film may be joined by a dry laminating method. As the material of the sealant film, low density polyethylene, linear low density polyethylene, polypropylene or the like can be used.
Alternatively, an extrusion method may be used in which a molten thermoplastic resin such as polyethylene resin is extruded and joined between the plastic film 14 and a previously prepared sealant film to be the adhesive layer 12.

In addition, an extrusion method may be used in which a molten thermoplastic resin is extruded in a film shape on the surface of the aluminum foil 13 opposite to the plastic film 14 and is cooled and solidified to form the adhesive layer 12. As the resin used in the above extrusion method, low density polyethylene, linear low density polyethylene, polypropylene or the like can be used.

(Molded sheet)
The molded sheet 11 used for the PTP1 of the present invention is a known container in which a large number of pocket portions 21 are formed so as to be surrounded by the flange portion 22, and for example, a resin sheet such as polypropylene, vinyl chloride, polyethylene terephthalate is used, It can be molded by plug-assist molding, vacuum molding, pressure molding, vacuum pressure molding, hot pressing and the like. After accommodating the tablets 15 and the like in the molded sheet 11, the opening is covered with the lid member 10 and heat-sealed to seal the sheet.

(Perforations, ears)
Like the commercially available PTP, the PTP 1 of the present invention may be provided with a separating perforation 26 so as to penetrate the region where the lid material 10 and the molding sheet 11 are bonded. The dose may be divided into one dose, or the perforations 26 may be used to provide a necessary amount of drug.
Further, an ear portion 27 as shown in FIG. 1 can be provided on at least one side of the peripheral edge of the PTP 1, and the name of drug, model name, lot number, etc. can be described.

(Packaging of tablets, etc.)
Tablets 15 and the like are filled in the pocket portion 21 of the molded sheet 11 and joined while aligning with the lid member 10 described above, and then punched into an appropriate size to complete a PTP having a predetermined specification.

The present invention will be described more specifically by way of examples. The test bodies used are Examples 1 to 4 and Comparative Examples 1 and 2, all of the test bodies use the same material, and the lamination process is also the same. Further, the pitch of the pocket portion of the container is 17 mm, the shape of the pocket portion is circular, and the outer diameter is 10 mm.

(Example 1)
The layer structure of the lid material is as follows.
[Outside] Polyethylene terephthalate (PET) film 12 μm (Toyobo Co., Ltd. model T-4102) / Low density polyethylene 15 μm (Nippon Polyethylene Co., Novatec LC502) / Aluminum foil 9 μm (UACJ Foil JIS H4160 Alloy No. 1N30) ) / Polypropylene film 20 μm (F329RA manufactured by Prime Polymer Co., Ltd.) [Molding sheet side]
The raw material of the formed sheet before forming is a polypropylene sheet of 250 μm (Model NS3450 manufactured by Sumitomo Bakelite Co., Ltd.).

A method of manufacturing the above lid material will be described.
First, a pattern, a character, etc. are gravure-printed by back-printing on the surface of the lid material on which the PET film is joined, which is on the side of the molded sheet.

Next, the printed PET film is provided with an easy-opening portion by fine hole processing on the entire surface of the pocket portion by a surface fine hole processing machine. Depending on the required specifications, the easy-open portion may be processed on the entire surface of the lid material.
The processing of the fine holes may be performed inside the gravure printing machine, or may be performed in another step after the gravure printing. When it is carried out inside the gravure printing machine, the printing unit may be provided with a hole forming roll for processing. As for the fine hole processing and the score line processing, the fine hole processing and the score line processing may be performed by the same roll, or may be performed separately by independent rolls.
The fine holes have a diameter of about 0.3 mm and are processed at about 50 holes/cm ² .

Further, a scoring line is made at an appropriate position on the PET film by a surface scoring line processing machine. The score line is two straight lines that pass through the center of the pocket and are orthogonal to each other. The length of the score line is equal to half the diameter of the pocket, that is, the radius. (See FIG. 5(a))

The cut line is a straight line, but may be a curved line as long as it does not impair the unsealing property. As long as the curved line has an arc shape, it may have the same radius of curvature as the arc of the outer circumference of the pocket portion, or may have a radius of curvature of about half the arc of the outer circumference of the pocket portion.

15 μm of low-density polyethylene melted by an extrusion method is bonded to the printed surface of the PET film, 9 μm of aluminum foil prepared in advance is overlaid, and then cooled by a cooling roll. By cooling, the low-density polyethylene is cooled and solidified, and the above three-layer laminate is completed. Next, in the laminated body of the PET film and the aluminum foil bonded as described above, a polypropylene film of 20 μm is formed on the surface of the aluminum foil, which is the molded sheet side, by an extrusion method, and then cooled by a cooling roll. By cooling, the polypropylene film is solidified to complete the laminated body of the lid material.

The score line processing and/or the fine hole processing may be performed by a laser processing method after the laminated body of the lid material is completed.
As described in the previous paragraph, scoring and/or perforating may be performed after the PET film printing process.
Any of the above-described processing steps and processing methods may be used, and the scoring line processing and the fine hole processing may be performed in different steps.

The molded sheet having a pocket is a polypropylene sheet having a diameter of 250 μm and a pocket formed by pressure molding.

After the tablet is filled in the pocket portion of the molded sheet, the molded sheet and the lid member are aligned with each other, and then heat sealing is performed.
After that, the outer shape of the member in which the molding sheet containing the tablets and the lid member are heat-sealed is trimmed to complete the PTP.

(Evaluation of opening property of PTP)
Using the above Examples 1 to 4 and Comparative Examples 1 and 2 prepared by filling tablets, the opening property of PTP was evaluated. After making 10 samples of each, the openability was evaluated. The evaluation was carried out by the evaluator by touching with the hands and visually.
The results are shown in Table 1.

The criteria for determining the ease of opening the PTP, which is an evaluation item in Table 1, are as follows.
⊚: Opening has started from the score line, and the opening resistance is sufficiently small.
◯: The opening line has the opening opening, and the opening resistance is large, but
This is within the allowable range.
X: Since there is no opening for opening, the resistance to opening is large and opening is difficult.

The evaluation criteria of the tablet, which is the evaluation item in Table 1, are as follows.
⊚: The resistance at the time of opening is appropriately increased, and the tablet extrusion speed is appropriately controlled, so that the tablet is unlikely to pop out.
◯: The resistance at the time of opening is gradually increased, and the tablet extrusion speed is controlled, so the tablets are somewhat unlikely to pop out. Not as good as ◎.
X: When opening, the tablet suddenly opens, so the tablet extrusion speed increases and the tablet pops out.
