Description

  The present invention provides a storage recess forming sheet in which a storage recess in which an article to be packaged is stored, a manufacturing method for manufacturing the storage recess forming sheet, and such a storage recess forming sheet and a lid side sheet. The present invention relates to a package body such as a configured press-through pack.

  Conventionally, a storage recess forming sheet formed with a storage recess for storing a medicine such as a tablet or capsule, cosmetics, food, etc. as a packaged object, and a storage recess of such a storage recess forming sheet A package called a press-thru pack composed of a lid-side sheet that is stuck to the storage recess forming sheet is used.

  As a storage recess forming sheet of such a press-through pack, conventionally, as shown in Patent Document 1, for example, a storage recess forming sheet configured by laminating a polyamide-based synthetic resin layer on an aluminum foil is used. Yes.

  However, in the storage recess forming sheet configured such that the polyamide resin layer is laminated on the aluminum foil in this manner, the polyamide resin is not so hard, and therefore an external tension or the like is applied to the polyamide resin layer. There was a risk of unintentional growth. And when a polyamide-type resin layer extended carelessly in this way, the problem that there exists a possibility that the printing pitch currently given to the polyamide-type resin layer may shift | deviate has arisen. In addition, such a polyamide resin layer has a problem that it may be curled by heat.

  On the other hand, an accommodation recess forming sheet configured by laminating a polyester resin layer such as polyethylene terephthalate on an aluminum foil is also used. In the storage recess forming sheet configured such that the polyester resin layer is laminated on the aluminum foil in this manner, the polyester resin layer is harder and less stretchable than the polyamide resin layer, so that it is not effective due to external tension. There is an advantage that it is less likely to be easily stretched, and since it has excellent heat resistance, it is less likely to curl due to heat.

  On the other hand, since the polyester resin layer is harder and less stretchable than the polyamide resin layer, a pinhole is formed in the aluminum foil laminated on the polyester resin layer when the storage recess for storing the packaged object is formed. There has been a problem that the aluminum foil may break.

Japanese Patent No. 3983131

  The present invention has been made to solve the above-described conventional problems, and there is a risk that the resin layer portion may be inadvertently extended during molding of the storage recess, and the printing pitch applied to the resin layer may be shifted. , And less likely to curl due to heat, and less likely to cause pinholes in aluminum foil or crack in aluminum foil during molding of storage recesses. It is an object of the present invention to provide a method for producing a storage recess forming sheet for a package and a package.

  The present invention has been made to solve the above problems, and the storage recess forming sheet of the packaging body of the present invention is formed with a storage recess for storing an object to be packaged, and the storage recess is closed by a lid side sheet. A storage recess forming sheet of the packaging body on the side where the storage recess is formed, the aluminum layer, and the polyamide resin layer and the polyester resin outside the aluminum layer It is characterized in that at least three layers with layers are laminated.

  Moreover, the manufacturing method of the storage recessed part formation sheet | seat of the package of this invention WHEREIN: The storage recessed part in which a to-be-packaged item is stored is formed, The said package recessed part is comprised by the lid side sheet | seat, A method for producing an accommodation recess forming sheet of a package on the side where an accommodation recess is formed, wherein an aluminum layer and at least three layers of a polyamide resin layer and a polyester resin layer outside the aluminum layer are laminated. Later, the storage recess is formed and manufactured so that the aluminum layer is on the inner surface side.

  Furthermore, the packaging body of the present invention includes a storage recess forming sheet in which a storage recess for storing an object to be packaged is formed, and a lid-side sheet adhered to the storage recess forming sheet so that the storage recess is closed.

A conventional storage recess in which a polyester resin layer is directly laminated on an aluminum layer by laminating a polyamide resin layer, which is easier to stretch than the polyester resin layer, on the polyester resin layer. There is less risk of pinholes or cracking in the aluminum layer as in the formed sheet.

  In the present invention, since the polyester resin layer that is harder and less stretched than the polyamide resin layer is laminated on the polyamide resin layer, only the polyamide resin layer is laminated on the aluminum layer. Like a recessed part formation sheet, there is less possibility that the resin layer will be inadvertently stretched due to external tension or the like, thereby reducing the possibility that the printing pitch applied to the resin layer is shifted. Further, since the polyester resin layer is superior in heat resistance as compared with the polyamide resin layer, it is curled by heat like a conventional storage recess forming sheet in which only the polyamide resin layer is laminated on the aluminum layer. There is less fear.

  As described above, according to the present invention, there is little risk of the resin layer portion being inadvertently stretched at the time of forming the storage recess and the print pitch applied to the resin layer being shifted, and the curl due to heat.

Among these, polycapramide (nylon-6), polyhexamethylene adipamide (nylon-6, 6), caprolactam / hexamethylene diammonium adipate copolymer (nylon-6 / 6, 6) are preferably used. Is done.

  Moreover, an aromatic polyamide may be added to an aliphatic polyamide and used. Examples of the aromatic polyamide include a mixture of an aromatic diamine such as meta-xylene diamine and para-xylene diamine with a dicarboxylic acid such as adipic acid, suberic acid, sebacic acid, cyclohexanedicarboxylic acid, terephthalic acid, and isophthalic acid, or a derivative thereof. A crystalline aromatic polyamide obtained by a condensation reaction can be used. Alternatively, an amorphous aromatic polyamide (amorphous nylon) obtained by a polycondensation reaction between an aliphatic diamine such as hexamethylene diamine and a dicarboxylic acid such as terephthalic acid or isophthalic acid or a derivative thereof can also be used.

  Further, the polyester resin constituting the polyester resin layer is obtained by polycondensation of dicarboxylic acid and diol. For example, the component derived from dicarboxylic acid is terephthalic acid, and the component derived from diol is ethylene glycol. The components derived from polyethylene terephthalate, dicarboxylic acid are terephthalic acid (99 to 80 mol%) and isophthalic acid (1 to 20 mol%), and the component derived from diol is ethylene glycol, an isophthalic acid copolymerized polyethylene terephthalate, dicarboxylic acid Sulfoisophthalic acid copolymer polyethylene in which the component derived from the acid is terephthalic acid (99.5 to 90 mol%) and 5-sodium sulfoisophthalic acid (0.5 to 10 mol%), and the component derived from the diol is ethylene glycol Terephthal Over door or the like is used.

  A polyamide resin layer and a polyester resin layer are laminated outside the aluminum layer. A polyamide resin layer is laminated outside the aluminum layer, and a polyester resin layer is laminated outside the polyamide resin layer. desirable. This is because by laminating the polyester resin layer on the outermost side, the inner polyamide resin layer is protected by the polyester resin layer, and inadvertent elongation of the polyamide resin layer is more reliably prevented. However, the polyester-type resin layer may be laminated | stacked on the outer side of the aluminum layer, and the polyamide-type resin layer may be laminated | stacked on the outer side.

  Furthermore, a thermal adhesive layer is laminated on the inner surface side of the aluminum layer, that is, the surface opposite to the surface on which the polyamide resin layer and the polyester resin layer are laminated. Examples of the thermal adhesive layer include high-density polyethylene, medium-density polyethylene, low-density polyethylene, linear linear polyethylene, unstretched polypropylene (CPP), carboxylic acid-modified polyethylene, carboxylic acid-modified polypropylene, polyolefin resins such as chlorinated polypropylene, Saturated polyester resin, EAA (ethylene-acrylic acid copolymer resin), EMAA (ethylene-methacrylic acid copolymer resin), EEA (ethylene-ethyl acrylate copolymer resin), EMAC (ethylene-methyl acrylate copolymer resin), ionomer, Examples thereof include carboxylic acid-modified EVA resin, polyvinyl chloride resin, and polystyrene resin. Among these, polyolefin resins and polyvinyl chloride resins are particularly preferably used. In addition, a resin layer may be interposed between the aluminum layer and the thermal adhesive layer.

Although the material of this lid | cover side sheet | seat is not specifically limited, For example, what laminated | stacked the heat bonding layer on the one surface side of the aluminum layer which consists of aluminum foil is used. As the thermal adhesive layer, for example, those listed above are used.

  As another embodiment, the present invention can also be applied to a package in which a storage recess is formed in both of two sheets facing each other. The two sheets in which the storage recesses are formed in this way are configured by laminating at least three layers of an aluminum layer, a polyamide resin layer and a polyester resin layer outside the aluminum layer, If necessary, a thermal adhesive layer as described above is laminated on the inner surface side of the aluminum layer.

  In addition, the use of the package of the present invention is not limited to the pharmaceuticals, foods, cosmetics and the like as described above, and the use is not questioned.

  Hereinafter, more specific embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the storage recess forming sheet 7 of one embodiment has a total of four layers of a polyester resin layer 1, a polyamide resin layer 2, an aluminum layer 4, and a thermal adhesive layer 5, which are laminated in order from the outside. The four-layer laminated sheet 6 is press-formed from the inner side toward the outer side, so that the storage recess 8 is formed.

  In the present embodiment, polyethylene terephthalate is used as the polyester constituting the polyester-based resin layer 1, and polyhexamethylene adipamide (nylon-6, 6) is used as the polyamide-based resin constituting the polyamide-based resin layer 2. Polyvinyl chloride resin is used as the resin constituting the thermal bonding layer 5. The aluminum layer 4 is made of an aluminum foil. In this case, instead of polyhexamethylene adipamide, polycapramide (nylon-6,6) or caprolactam / hexamethylenediammonium adipate copolymer (nylon-6 / 6,6) can also be used.

  Next, an embodiment of a method for producing such a housing recess forming sheet 7 will be described. First, as shown in FIG. 2, a polyester resin layer 1 and a polyamide resin layer 2 are laminated to obtain a laminated resin sheet 3. The laminated resin sheet 3 obtained in this way is attached to the aluminum foil constituting the aluminum layer 4 as shown in FIG. In this case, the laminated resin sheet 3 is attached to the aluminum foil so that the polyamide resin layer 2 side is laminated on the aluminum layer 4.

  Next, as shown in FIG. 4, a polyvinyl chloride resin sheet is attached to the surface of the aluminum layer 4 opposite to the surface on which the polyamide resin layer 2 is laminated, and the thermal adhesive layer 5 is attached. Laminate. In this way, a laminated sheet 6 composed of a total of four layers, that is, a polyester resin layer 1, a polyamide resin layer 2, an aluminum layer 4, and a heat bonding layer 5, is obtained.

  Next, as shown in FIG. 1, the laminated sheet 6 is pressed from the thermal adhesive layer 5 side by press molding to form a storage recess 8 as shown in the figure. By forming the storage recess 8 in this way, the article to be packaged can be stored on the inner surface side of the storage recess 8.

  In this case, the polyamide resin layer 2 is laminated on the aluminum layer 4 so as to be positioned on the aluminum layer 4 side, and the polyamide resin layer 2 is interposed between the polyester resin layer 1 and the aluminum layer 4. Therefore, when the storage recess 8 is formed by press molding, a polyamide resin layer that is easier to extend than the polyester resin layer is interposed, so that the polyester resin layer is directly laminated on the aluminum layer. In addition, the possibility of pinholes in the aluminum layer and the possibility of cracks are reduced as in the conventional storage recess forming sheet.

  In addition, since the polyester resin layer that is harder and less stretched than the polyamide resin layer is laminated on the polyamide resin layer, only the polyamide resin layer is attached to the aluminum layer. As described above, the inadvertent elongation of the polyamide-based resin layer caused by external tension or the like is alleviated, thereby reducing the possibility that the printing applied to the resin layer is shifted. In particular, since the polyester resin layer 1 is laminated on the outer side of the polyamide resin layer 2, the possibility that the polyamide resin layer 2 is unintentionally extended by being protected by the polyester resin layer 1 is further reduced. In addition, since the polyester resin layer has better heat resistance than the polyamide resin layer, it may curl due to heat like a conventional storage recess forming sheet in which only the polyamide resin layer is attached to the aluminum layer. Less.

  By forming the storage recess 8 as described above, a storage recess forming sheet 7 as shown in FIG. 1 is obtained.

  Next, as shown in FIG. 5, the lid side sheet 9 is prepared. The lid-side sheet 9 is configured by laminating a thermal adhesive layer 11 on one surface side of an aluminum layer 10 made of aluminum foil. As the thermal bonding layer 11, a layer made of polyvinyl chloride resin is used.

  Next, as shown in FIG. 6, after the article 13 is stored in the storage recess 8 of the storage recess forming sheet 7, the lid side sheet 9 is closed so that the opening 8 a of the storage recess 8 is closed. The lid-side sheet 9 is thermally bonded to the storage recess forming sheet 7 so that the thermal adhesive layer 11 faces the storage recess forming sheet 7. In this case, the thermoadhesive layer 5 is provided on the side of the storage recess forming sheet 7 facing the lid side sheet 9, and the side of the storage recess forming sheet 7 facing the lid side sheet 9 is the same. Since the heat bonding layer 11 made of the material polyvinyl chloride resin is provided, the storage recess forming sheet 7 and the lid side sheet 9 are suitably heat bonded. As the packaged item, for example, a drug is used.

  In this way, a package 14 as shown in FIG. 6 is obtained.

  That is, as shown in the figure, the packaging body 14 of one embodiment has a total of four layers of a polyester resin layer 1, a polyamide resin layer 2, an aluminum layer 4, and a heat bonding layer 5 stacked in order from the outside. , A storage recess forming sheet 7 that is press-formed from the inside to the outside to form a storage recess 8, and a lid-side sheet 9 in which a thermal adhesive layer 11 is laminated on one surface side of the aluminum layer 10. It is. And the to-be-packaged goods 13 are accommodated in the accommodation recessed part 8 of the accommodation recessed part formation sheet 7. FIG.

  In the above embodiment, as shown in FIG. 6, the package is constituted by the storage recess forming sheet 7 and the lid side sheet 9, but not limited to this, as shown in FIG. The package may be constituted by the recess forming sheet 7. As shown in FIG. 7, such a package has a total of four layers, a polyester resin layer 1, a polyamide resin layer 2, an aluminum layer 4, and a heat bonding layer 5, which are laminated in order from the outside. The two storage recess forming sheets 7 and 7 that are press-molded toward the storage recess 8 are formed so that the storage recesses 8 and 8 of the storage recess forming sheets 7 and 7 face each other. It is configured to be worn.

  Examples of the present invention will be described below.

  A laminate of a polyethylene terephthalate film and a nylon-6 film was attached to one side of an aluminum foil, and a polyvinyl chloride film for thermal bonding was attached to the other side of the aluminum foil to produce a storage recess forming sheet. (Example 1).

  Moreover, only the polyethylene terephthalate film was stuck on the one surface side of the aluminum foil, and the polyvinyl chloride film for heat bonding was stuck on the other surface side of the aluminum foil to prepare a storage recess forming sheet (Comparative Example 1).

  Furthermore, only the nylon-6 film was stuck on one surface side of the aluminum foil, and the polyvinyl chloride film for heat bonding was stuck on the other surface side of the aluminum foil to prepare a storage recess forming sheet (Comparative Example 2). .

  A pocket (housing recess) having a diameter of 11 mm and a depth of 3.5 mm is press-formed on the three types of storing recess forming sheets of Example 1, Comparative Example 1, and Comparative Example 2 using a continuous molding machine, and further formed into an aluminum foil. The lid side sheet laminated with the heat bonding layer is heat-sealed, and the pinholes and cracks in the aluminum foil and the printing shift of the storage recess formation sheet are carried out for the storage recess formation sheets of Example 1, Comparative Example 1 and Comparative Example 2. Evaluation of curling due to heat was performed.

  The evaluation results are shown in Table 1. In Table 1, ○ in the evaluation item of pinhole / cracking of aluminum foil means that pinhole / cracking of aluminum foil did not occur after press molding and heat sealing, and × represents aluminum foil after press molding and heat sealing. This means that pinholes / cracks have occurred. In the evaluation item of printing deviation of the storage recess forming sheet, ○ means that no printing deviation occurred after press molding and heat sealing, and × means that printing deviation occurred after press molding and heat sealing. . Further, in the evaluation item of curl due to heat of the storage recess forming sheet, ◯ means that no curling has occurred after press molding and heat sealing, and × means that curling has occurred after press molding and heat sealing. Further, ◯ in the comprehensive evaluation means that all evaluation items are good, and Δ means that some evaluation items are good, but other evaluation items are bad.

  As is clear from Table 1, in the storage recess forming sheet of Example 1, pinholes and cracks of the aluminum foil did not occur after press molding and heat sealing, and printing misalignment did not occur. Further, after the storage recess forming sheet was heat sealed with the lid side sheet, no curling due to heat occurred.

  On the other hand, in the storage recess forming sheet of Comparative Example 1, printing misalignment and curling due to heat did not occur, but pinholes and cracks in the aluminum foil occurred. On the other hand, in the storage recess forming sheet of Comparative Example 2, pinholes and cracks in the aluminum foil did not occur, but printing misalignment and curling due to heat occurred.

  For this reason, the storage recess forming sheet of Example 1 had no defects with respect to all the evaluation items of pinholes and cracks in the aluminum foil, printing deviation of the storage recess forming sheet, and curling due to heat. Thus, in the comprehensive evaluation, all the evaluation items in Example 1 were good, but in the storage recess forming sheets of Comparative Example 1 and Comparative Example 2, some of the evaluation items were good, The evaluation items were found to be poor.
