Description

  The present invention relates to a PTP packaging container suitable for containing a medicine composed of capsules and tablets, and confectionery such as granular chocolate.

  As a packaging container suitable for containing drugs such as capsules and tablets, and confectionery such as granular chocolate and ramune, a bottom material with a plurality of recesses for containing contents and a top surface of the bottom material are pasted. PTP packaging containers having a lid material that is attached and holds the contents hermetically in the recesses are widely adopted.

  When storing the contents in this PTP packaging container, the bottom material made of a synthetic resin sheet formed with a plurality of concave portions is arranged so that the opening of the concave portion is located on the upper side, and each concave portion of the bottom material is arranged. The contents are sequentially loaded, and then a lid made of aluminum foil or the like is attached to the bottom by heat sealing or the like, and the recesses are hermetically sealed to accommodate the contents. Moreover, when taking out the contents from the PTP packaging container, the concave portion is pressed and deformed to the lid material side, the lid material is broken with the contents, and the contents are taken out.

  By the way, as said PTP packaging container, in order to be able to maintain the quality of the contents for a long period of time, both the bottom material and / or the cover material are composed of a sheet material provided with an absorption layer that absorbs oxygen and odor. The thing is also proposed (for example, refer patent document 1, 2).

JP 2011-42371 A JP 2006-334819 A

  However, in the PTP packaging containers described in Patent Documents 1 and 2, in order to absorb oxygen and odor in the recess, a heat seal layer that transmits oxygen and odor is interposed between the absorption layer and the bottom material, or an absorbent is used. The kneaded heat seal layer is placed on the bottom material side, but in the former case, the heat seal layer material has adhesiveness with the absorbent layer, and oxygen and odor permeability The material selection range of the heat seal layer is greatly limited, and in the latter case, the content touches the absorbent kneaded in the heat seal layer, resulting in a decrease in quality. There is a concern to do.

  In addition, the material sheets that make up the lid and bottom material are manufactured by the manufacturer, but the loading of the contents is performed by pharmaceutical manufacturers, confectionery manufacturers, etc. After being manufactured by the material sheet manufacturer, it is stored in a roll for a relatively long time until it is used by a pharmaceutical manufacturer or a confectionery manufacturer. For this reason, in the inventions described in Patent Documents 1 and 2, the absorption layer absorbs oxygen and odor while the material sheet constituting the lid material is stored, and when the contents are loaded, the absorption action is already present. There was a problem that it was falling.

  The object of the present invention is to absorb moisture, oxygen, carbon dioxide, odor, etc. in the recess, and effectively prevent deterioration of the contents, and prevent the contents from coming into direct contact with the absorbent layer. However, it is providing the PTP packaging container which can expand the freedom degree with respect to raw materials, such as a heat seal layer arrange | positioned between an absorption layer and a bottom material.

  The PTP packaging container according to the present invention includes a bottom material in which a plurality of recesses for containing the contents are formed, and a lid material that is adhered to the upper surface of the bottom material and holds the contents in an airtight manner in the recesses. A PTP packaging container, wherein the lid member is formed of a sheet body having at least a three-layer structure including a first barrier layer, an absorption layer, and a second barrier layer in order from the bottom material side, and penetrates the first barrier layer. Thus, a communication hole that connects the absorption layer and the recess is formed. However, in the present specification, the “communication hole” means not only a mere independent hole but also a groove or a notch.

  In this PTP packaging container, the absorption layer communicates with the recess through the communication hole, and the absorption object such as moisture, oxygen, carbon dioxide, odor and the like in the recess can be absorbed through the communication hole. It is possible to effectively prevent a problem that the quality of the contents is lowered due to the contact. Moreover, since at least the first barrier layer is disposed between the bottom material and the absorption layer, it is possible to prevent the contents from coming into direct contact with the absorption layer, and the quality of the contents due to the contact with the absorption layer. A drop can also be reliably prevented. Moreover, since the 2nd barrier layer which does not have a communicating hole on the opposite side to the bottom material of an absorption layer is formed, the inside of a recessed part is airtightly maintained by this 2nd barrier layer, and the contents are outside air. The contact can be prevented, and the quality deterioration of the contents due to contact with the outside air can be surely prevented. Further, since the absorption layer is provided between the first barrier layer and the second barrier layer, the communication sheet is formed immediately before packaging the contents, so that the material sheet constituting the cover material is manufactured, and then the cover material. In the period from pasting to the bottom material and packaging the contents, the absorption layer absorbs external moisture, oxygen, carbon dioxide, odor, etc., and can also prevent a problem that the absorption performance is lowered. Furthermore, since moisture, oxygen, carbon dioxide, odor, etc. in the recess can be absorbed through the communication hole, the degree of freedom in selecting a material such as the first barrier layer disposed between the absorption layer and the bottom material can be greatly increased.

  Here, it is a preferred embodiment that the absorbing layer absorbs one or more selected from water, oxygen, carbon dioxide, and odor. The absorption object to be absorbed by the absorption layer can be arbitrarily set according to the contents accommodated in the PTP packaging container. For example, as in the present invention, 1 selected from oxygen, carbon dioxide, and odor It can be configured to absorb seeds or two or more.

  An aluminum foil is used as the first barrier layer, a heat seal layer is formed on the bottom material side of the first barrier layer, and the communication hole is formed so as to penetrate the heat seal layer and the first barrier layer. Is also a preferred embodiment. As the first barrier layer, an aluminum foil is preferably used because of excellent gas barrier properties.

  In a preferred embodiment, the communication hole is formed so that the absorbent layer does not directly contact the contents. By comprising in this way, the quality fall of the content by contacting an absorption layer can be prevented reliably.

  As the sheet body, a sheet formed by forming a communication hole in the first barrier layer and laminating the second barrier layer and an absorption layer may be used. In this case, in the sheet manufacturer, a communication hole is formed in the first barrier layer, and this is laminated on the second barrier layer and the absorption layer to produce a sheet body constituting the lid member. Since it is transported to a pharmaceutical manufacturer and attached to the bottom material loaded with contents in the pharmaceutical manufacturer or the like, the pharmaceutical manufacturer or the like does not need to form a communication hole. However, in this case, since the communicating holes are formed in the sheet body constituting the lid material at the stage of the material sheet, external moisture, oxygen, carbon dioxide, odor, etc. are absorbed into the absorption layer through the communicating holes. The For this reason, the sheet body manufactured by the sheet body manufacturer is rolled with the communication hole side inward, so that external moisture, oxygen, carbon dioxide, odor, etc. do not enter from the communication hole. It is preferable to prevent external moisture, oxygen, carbon dioxide, odor, and the like from being absorbed by the absorbent layer by, for example, loading a sheet roll into a sealed bag containing an absorbent.

  It is also a preferred embodiment that the communication hole is formed in the first barrier layer of the sheet body immediately before the cover material is attached to the upper surface of the bottom material. In this case, since a communicating hole is formed in the sheet body in a pharmaceutical manufacturer or the like, the equipment burden in the pharmaceutical manufacturer or the like is increased. However, external moisture, oxygen, Since it is possible to prevent carbon dioxide, odors and the like from being absorbed, it is possible to prevent the performance of the absorbent layer from deteriorating before the lid is attached. Even in this case, in order to prevent external moisture, oxygen, carbon dioxide, odor, etc. from entering from the side edge of the material sheet, the sheet body manufactured by the sheet body manufacturer is rolled up. It is preferable to load this into a sealed bag containing an absorbent to prevent external moisture, oxygen, carbon dioxide, odor and the like from being absorbed into the absorbent layer.

  It is also a preferred embodiment to apply an emetic to the bottom or lid. For example, when using multiple types of medicines, etc., in order to avoid mistakes in the type and number of medicines used at one time, the PTP packaging container is separated with a scissors etc. In general, it is generally accommodated in a dedicated case or the like. However, when the PTP packaging container is carved with a scissors or the like in this way, sharp corners are formed in the carved PTP packaging container, and the elderly or infants accidentally swallow the carved PTP packaging container, In some cases, the esophagus was damaged. In the present invention, if the cut PTP packaging container is mistakenly put in the mouth, it will be spit out by the emetic. Therefore, the PTP packaging container put in the mouth is prevented from being swallowed as it is and the esophagus is damaged by accidental ingestion. Problems can be prevented in advance.

  According to the PTP packaging container of the present invention, the absorption layer is communicated with the recess through the communication hole, and absorption objects such as moisture, oxygen, carbon dioxide, and odor in the recess can be absorbed through the communication hole. It is possible to effectively prevent a problem that the quality of the contents is lowered due to contact with the object to be absorbed. Moreover, since at least the first barrier layer is disposed between the bottom material and the absorption layer, it is possible to prevent the contents from coming into direct contact with the absorption layer, and the quality of the contents due to the contact with the absorption layer. A drop can also be reliably prevented. Moreover, since the 2nd barrier layer which does not have a communicating hole on the opposite side to the bottom material of an absorption layer is formed, the inside of a recessed part is airtightly maintained by this 2nd barrier layer, and the contents are outside air. The contact can be prevented, and the quality deterioration of the contents due to contact with the outside air can be surely prevented. Further, since the absorption layer is provided between the first barrier layer and the second barrier layer, the communication sheet is formed immediately before packaging the contents, so that the material sheet constituting the cover material is manufactured, and then the cover material. In the period from pasting to the bottom material and packaging the contents, the absorption layer absorbs external moisture, oxygen, carbon dioxide, odor, etc., and can also prevent a problem that the absorption performance is lowered. Furthermore, since moisture, oxygen, carbon dioxide, odor, etc. in the recess can be absorbed through the communication hole, the degree of freedom in selecting a material such as the first barrier layer disposed between the absorption layer and the bottom material can be greatly increased.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1 to FIG. 4, the PTP packaging container 1 includes a bottom material 3 in which a plurality of recesses 2 for containing the contents S are formed, and the contents S attached to the upper surface of the bottom material 3. A lid member 4 that is airtightly held therein, and the lid member 4 includes at least four layers of a heat seal layer 5, a first barrier layer 6, an absorption layer 7, and a second barrier layer 8 in order from the bottom member 3 side. The sheet body has a structure and is formed with a communication hole 9 that penetrates the heat seal layer 5 and the first barrier layer 6 and communicates the absorption layer 7 and the recess 2.

  As the contents S that can be accommodated in the PTP packaging container 1, capsules, granular or lump pharmaceuticals, foods, and the like such as medicines such as capsules and tablets, and confectionery such as granular chocolate and ramune can be accommodated. In particular, in the present invention, moisture (humidity), oxygen, carbon dioxide, odor, and the like can be absorbed, so that contents that dislike contact with these gas bodies can be suitably accommodated.

  The bottom material 3 is formed by forming a large number of recesses 2 having a size capable of accommodating the contents S in a long band-like sheet material by vacuum forming, vacuum pressure forming, or the like, for example, 10 in 2 rows and 5 columns. The sheet material is cut and manufactured so that the individual recesses 2 are arranged. The shape of the concave portion 2 can be appropriately set according to the shape of the content S, and can be formed into, for example, a circular shape, an elliptical shape, an oval shape, or a rectangular shape in plan view. In addition, the number of the recessed parts 2 formed in one bottom material 3 can be arbitrarily set according to the number of contents S accommodated in the PTP packaging container 1.

  The bottom material 3 is a sheet made of a known synthetic resin material such as polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), ethylene-vinyl alcohol copolymer resin (EVOH), nylon, polyvinyl chloride (PVC), etc. A transparent synthetic resin sheet material that can be made of a material, has excellent gas barrier properties, and allows the contents S to be seen through from the bottom material 3 side so that intrusion of foreign matter or the like into the recess 2 can be easily inspected. It is preferable to comprise. Specifically, it is preferable to use an ethylene-vinyl alcohol copolymer.

  The thickness of the bottom material 3 can be arbitrarily set, but can be set to, for example, 100 μm to 300 μm so that vacuum forming or vacuum / pressure forming is possible and the content S can be easily taken out by pushing the concave portion 2 with a finger from the outside. Is preferred.

  Since the first barrier layer 6 and the second barrier layer 8 are excellent in various gas barrier properties such as moisture, oxygen, carbon dioxide, odor and the like, they are made of aluminum foil or aluminum vapor deposition layer having a thickness of 15 μm to 25 μm. Can be suitably employed. However, the first barrier layer 6 and the second barrier layer 8 can be made of the same material, but can also be made of different materials, and the first barrier layer 6 or the second barrier layer 8 At least one of them can be made of a synthetic resin material having excellent gas barrier properties, such as ethylene-vinyl alcohol copolymer (EVOH). Further, when the first barrier layer 6 is made of a synthetic resin material having a heat seal function with respect to the bottom material 3, the heat seal layer 5 can be omitted.

The absorbent layer 7 is made of a sheet material obtained by kneading an absorbent with a base material made of a synthetic resin material, and absorbs one or more selected from moisture, oxygen, carbon dioxide, and odor. It is. As the absorbent, when absorbing moisture (humidity), calcium oxide, alumina desiccant, silica gel, magnesium salt, zeolite and the like are employed. When oxygen is absorbed, metal powders such as iron and zinc, reducing lower oxides of iron such as FeO, FeTiO ₂ and Fe ₂ O ₃ , sulfites, bisulfites, thiosulfates, oxalic acid Oxygen-absorbing polymers such as salt, pyrogallol, catechol, longgarit, glucose, vitamin C, oxygen-absorbing polyester, and the like are used. Furthermore, when absorbing carbon dioxide, lithium silicate, zinc oxide, zeolite, activated carbon, alumina, or the like is used. Furthermore, when absorbing odors, silica gel, activated alumina, titanium oxide, zinc oxide, carbon black, zeolite, and the like are used. These absorbents can be used alone or in any combination.

  As the synthetic resin material constituting the base material of the absorbent layer 7, those having high affinity with the absorbent are preferred, and for example, polyolefin resins such as polyethylene, ethylene copolymer, and polypropylene are preferred.

  As the heat seal layer 5, a synthetic resin material excellent in heat sealability with the bottom plate, for example, a polyolefin resin such as polyethylene, an ethylene copolymer, or polypropylene can be suitably used.

  The heat seal layer 5, the first barrier layer 6, the absorption layer 7, and the second barrier layer 8 constituting the lid member 4 are integrally formed by a known lamination technique such as extrusion lamination, dry lamination, wet lamination, and the like. Can be stacked.

  The heat seal layer 5 and the first barrier layer 6 have a communication hole 9 communicating with the absorbent layer 7 and the recess 2, and the contents S are loaded into the recess 2, and the lid 4 is pasted on the bottom material 3. In the worn state, the absorbent layer 7 can absorb moisture, oxygen, carbon dioxide, odor, and the like in the recess 2.

  As shown in FIG. 4A, the communication hole 9 is composed of perforated slits arranged in a circle along the inner side of the circumference corresponding to the peripheral wall portion 2 a of the recess 2 in the lid member 4. Yes. However, the shape, size, number, and formation position of the communication holes 9 can be arbitrarily set, and can be configured in an arc shape, a straight line shape, a dot shape, or a shape obtained by combining these shapes. It is preferably provided so that the content S does not come into direct contact with the absorbent layer 7 and when the concave portion 2 is pressed with a finger to take out the content S. In addition, it is preferable to form at a position where the lid member 4 is opened along the communication hole 9 by being pushed by the contents S. For example, instead of the communication hole 9 shown in FIG. 4 (a), a circular shape is formed along the inside of the circumference corresponding to the peripheral wall 2a of the recess 2 in the lid member 4 as shown in FIG. 4 (b). The four arc-shaped communication holes 9B arranged in FIG. 4 are formed, as shown in FIG. 4C, the two arc-shaped communication holes 9C arranged in a circle are formed, or the structure shown in FIG. As shown in FIG. 4E, an arc-shaped communication hole 9DR arranged in a semicircular shape and a linear communication hole 9DL extending continuously therewith are formed. As shown in FIG. As shown in FIG. 4 (f), four linear communication holes 9 </ b> F extending radially from a position corresponding to the central part of the recess 2 in the lid member 4 are formed. Can be formed.

  The communication hole 9 can be formed by punching the heat seal layer 5 and the first barrier layer 6 with a punch, or can be formed by cutting the heat seal layer 5 and the first barrier layer 6 with a blade. Further, the communication hole 9 can be formed when the material sheet of the lid member 4 is manufactured, or can be formed after the material sheet is manufactured.

  When the communication hole 9 is formed when the material sheet of the lid material 4 is manufactured, the communication hole 9 is formed in the heat seal layer 5 and the first barrier layer 6, and this is formed as the second barrier layer 8 and the absorption layer. The material sheet constituting the lid material 4 is manufactured by laminating with the material 7, and transported to a pharmaceutical manufacturer or the like, and adhered to the bottom material 3 loaded with the contents S in the pharmaceutical manufacturer or the like. In this case, a pharmaceutical manufacturer or the like does not need to perform an operation such as forming the communication hole 9 on the material sheet of the lid member 4, so that an economic burden on the pharmaceutical manufacturer or the like does not increase. However, in this case, since the communication hole 9 is formed in the sheet body constituting the lid member 4 at the stage of the material sheet, external moisture, oxygen, carbon dioxide, odor is introduced into the absorption layer 7 through the communication hole 9. Etc. are absorbed. For this reason, the material sheet manufactured by the sheet body manufacturer is rolled with the communication hole 9 side inward so that moisture, oxygen, carbon dioxide, odor, etc. from the outside do not enter through the communication hole 9. It is preferable to prevent external moisture, oxygen, carbon dioxide, odor, etc. from being absorbed by the absorbent layer 7 by, for example, loading a roll of material sheet into a sealed bag containing an absorbent. .

  In the case where the communication hole 9 is formed after the material sheet of the lid material 4 is manufactured, the communication hole 9 is formed in the material sheet of the lid material 4 in the pharmaceutical manufacturer or the like, so that the equipment burden on the pharmaceutical manufacturer or the like increases. However, it is possible to prevent external moisture, oxygen, carbon dioxide, odor and the like from being absorbed by the absorbent layer 7 until immediately before the communication hole 9 is formed, and thus the performance of the absorbent layer 7 is deteriorated before the cover 4 is adhered. Can be prevented. Even in this case, in order to prevent external moisture, oxygen, carbon dioxide, odor, etc. from entering from the side edge of the material sheet, the material sheet manufactured by the sheet body manufacturer is rolled up. It is preferable to load this in a sealed bag containing an absorbent to prevent external moisture, oxygen, carbon dioxide, odor, etc. from being absorbed by the absorbent layer 7.

  In this PTP packaging container 1, a bottom material 3 made of a synthetic resin sheet in which a plurality of recesses 2 are formed is arranged such that the opening of the recess 2 is positioned on the upper side, and the contents are stored in each recess 2 of the bottom material 3. The objects S are sequentially loaded, and then the lid 4 is superposed on the bottom material 3 with the heat seal layer 5 facing down, and the lid 4 is heat sealed to the bottom 3 so that the contents S are hermetically sealed in the recess 2. Will be housed. Further, when the contents S is taken out from the PTP packaging container 1, the recess 2 is pressed and deformed toward the lid 4, the lid 4 is pressed with the contents S, and the lid 4 is moved along the communication hole 9. It will break and take out the contents.

  On the other hand, in a state where the contents S are accommodated in the PTP packaging container 1, the absorbent layer 7 is communicated with the recess 2 through the communication hole 9, and moisture, oxygen, carbon dioxide, odor in the recess 2 is communicated with the communication hole 9. Therefore, it is possible to effectively prevent a problem that the quality of the content S is deteriorated due to contact with these absorption objects. Moreover, since the heat seal layer 5 and the first barrier layer 6 are disposed between the bottom material 3 and the absorption layer 7, it becomes possible to prevent the contents S from coming into direct contact with the absorption layer 7, The deterioration of the quality of the contents S due to contact with the absorbent layer 7 can also be reliably prevented. Further, since the second barrier layer 8 that does not have the communication hole 9 is formed on the side opposite to the bottom material 3 of the absorption layer 7, the inside of the recess 2 is kept airtight by the second barrier layer 8. The contents S can be prevented from coming into contact with the outside air, and the quality deterioration of the contents S due to the contact with the outside air can be reliably prevented. Furthermore, since moisture, oxygen, carbon dioxide, odor, etc. in the recess 2 can be absorbed through the communication hole 9, selection of materials for the heat seal layer 5 and the first barrier layer 6 disposed between the absorption layer 7 and the bottom material 3 is possible. The degree of freedom can be greatly expanded.

  In addition, it is also a preferred embodiment to apply an emetic to the outer surface of the PTP packaging container 1 having an emetic action when contained in the mouth. That is, when the PTP packaging container 1 is carved with a scissors or the like or cut along the perforation, sharp corners are formed in the carved PTP packaging container 1, and the elderly, infants, etc. are carved. If the PTP packaging container 1 is accidentally swallowed, the esophagus may be damaged at the corners. Therefore, by applying an emetic to the outer surface of the PTP packaging container 1, if the cut PTP packaging container 1 is accidentally put into the mouth, the PTP packaging container 1 will be spit out, so the PTP packaging container placed in the mouth It is possible to prevent swallowing 1 as it is, and to prevent a problem that the esophagus is damaged by accidental ingestion. The configuration in which the emetic is applied to the outer surface of the PTP packaging container 1 in this way can also be applied to a well-known PTP packaging container 1 that does not include the absorption layer 7.

  The emetic may be applied to the entire outer surface of the PTP packaging container 1 as long as it is applied to at least a part of the separated PTP packaging container 1. It can be applied to the entire surface or only part of it.

  As an emetic, a bitter emetic, a sour emetic, a spicy emetic, etc., which has an emetic action when contained in the mouth and is not toxic, can be made of known materials. . In terms of emetic action, bitter emetics are effective, and compounds such as terpenes, xanthine derivatives, alkaloids, terpene glycosides, triterpenoid derivatives and the like can be employed. Specifically, denatonium benzoate, octaacetylated sucrose, hops, caffeine, Kawaratake extract, chrysanthemum extract, yellowfin extract, spice extract, Japanese matsutake extract, litchi extract, naringin enzyme treated product, dimethoki Strikeny nebulcine (brucine), humulone, lupron, isohumulone, luptrione, natural caffeine, synthetic caffeine, quinine, quinidine, cinchonine, tannin, quillajasaponin, quillajasapogenin, quilayaic acid, berberine, gentiopicrin, limonin, theobromine, naringin , Flavanone, cassiine, neo-cassiin, nigaki lactone A-L, nigaquinone, picracin A-G, methylnigaquinone, abscintin, boraptoside, boraptol, methylthioadenosine, caffetannin, etc. can be adopted . Citric acid, tartaric acid, lactic acid, acetic acid, glacial acetic acid, fumaric acid, sodium fumarate, malic acid, adipic acid, etc. can be used as the sour emetic, and piperine, shabicin, capsaicin, α-sansho can be used as the spicy emetic. All, β-sanshool, gingerone, shogaol, isothiocyanate and the like can be employed.

  In the present embodiment, the barrier layer is formed only on the lid member 4 side so that the contents S can be seen through from the bottom member 3 side. However, when the see-through is unnecessary, the gas barrier property of the bottom member 3 is improved. Therefore, it is possible to provide a barrier layer having excellent gas barrier properties such as an aluminum foil in a laminated form on the sheet material constituting the bottom material 3. In this case, an absorption layer that absorbs moisture, oxygen, carbon dioxide, odor and the like is laminated on the sheet material constituting the bottom material 3 so as not to be exposed in the recess 2, and on the recess 2 side of the absorption layer. By forming a gas permeable synthetic resin layer as the synthetic resin layer to be disposed or by forming a communication hole communicating with the absorption layer in the synthetic resin layer on the concave portion 2 side, moisture, oxygen in the concave portion 2 is formed. It is also a preferred embodiment to be configured to absorb carbon dioxide, odor, and the like.

  The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and it goes without saying that the configuration can be changed without departing from the gist of the present invention.
