Description

  The present invention wraps transpirational drugs such as fragrances, deodorants, insect repellents, etc., and prevents transpiration of chemicals during storage, and transpiration of chemicals can be evaporated to the outside through a drug permeable film during use. It relates to the container.

  Conventionally, for volatile liquid or gel-like fragrances, the fragrance is sealed and stored in a bag or molded container made of a gas barrier packaging material through which the fragrance gas does not permeate. At times, a packaging form was adopted in which a part of a bag or a molded container was opened and gas was volatilized to the outside.

  In such a conventional packaging form, the fragrance flows out or scatters when the bag or molded container is opened, and the leaked fragrance contaminates the user's hand and surroundings, or the volume of the fragrance decreases, so that the usage time is increased. There was a problem of shortening.

  Therefore, various packaging forms that improve the usability of the encapsulated fragrance have been proposed. For example, Patent Document 1 discloses that the inner surface has a heat-sealing property and includes a multilayer film including a drug blocking film. A fragrance package is disclosed in which a packaging bag is filled and sealed with a volatile fragrance, and the inner packaging bag is hermetically sealed with an outer packaging bag or container at least partially made of a drug-permeable film. And, by selecting and using a heat-adhesive resin with low heat-seal strength as the inner-layer resin layer of the inner-packaging bag, it is possible to easily break the heat-sealed portion by strongly pressing the inner-packaging bag when using the fragrance. ing.

Japanese Utility Model Publication No. 60-1730

  In the fragrance packaged body of Patent Document 1, a multilayer film having a special specification in which a heat-adhesive resin layer having a low heat seal strength is laminated is used as the inner resin layer. Also, if the heat-sealing strength of the inner packaging bag is too strong, the unsealing property at the time of use is lowered, and if the heat-sealing strength is too weak, the inner packaging bag may be inadvertently broken during distribution, Since the heat seal strength is determined depending on the kind of the heat-adhesive resin used as the inner resin layer, it is difficult to adjust the heat seal strength according to the purpose of use. In addition, since the heat seal strength cannot be partially adjusted, it is difficult to break from a specific region of the inner packaging bag during use.

  In view of the above problems, an object of the present invention is to provide a chemical evaporation container capable of easily adjusting the heat seal strength of the inner packaging bag and capable of breaking a specific region of the heat seal portion.

  In order to achieve the above object, the present invention has a storage part in which a liquid or gel-like medicine is enclosed, and a seal part that seals the periphery of the storage part, and the enclosed medicine is not permeable. An inner packaging bag formed of a laminate including at least a drug-blocking film layer and a heat-adhesive resin layer that is the innermost layer, and the inner packaging bag is hermetically sealed and stored so that the gasified drug is permeated. A drug evaporation container having at least a part formed by a possible drug permeable film, wherein at least a part of the seal part is formed with a plurality of seal release parts and can be peeled off by pressing from the outside It is a weak seal part, At least one part of the said seal extraction part has the top part toward the inner edge side of the said seal part, It is characterized by the above-mentioned.

  Further, the present invention is the chemical vaporization container having the above-described configuration, wherein the weak seal portion includes a triangular seal-out portion having a top portion toward the inner edge side of the seal portion, and a top portion toward the outer edge side of the seal portion. It has a feature that triangle-shaped seal punched portions are alternately arranged along the longitudinal direction of the seal portion.

  According to the first configuration of the present invention, the inner packaging bag is broken by breaking the weak sealing portion formed with a plurality of seal-released portions by pressing the inner packaging bag from the outside of the outer container with a finger. The leakage of the medicine at the time can be prevented. Therefore, there is no possibility that the user's hand or surroundings will be contaminated, or the usage time will be shortened due to a decrease in the volume of the medicine. In addition, since at least a part of the plurality of seal-extracted portions have apexes toward the inner edge side of the seal portion, the heat seal strength of the weak seal portion can be easily reduced by using a normal heat-adhesive resin. It is not necessary to use a special specification resin with low heat seal strength as the conductive resin layer, and the manufacturing cost of the chemical evaporation container can be reduced. Furthermore, since the weak seal portion can be formed at a specific position of the inner packaging bag, it can be broken from a specific region of the inner packaging bag.

  Moreover, according to the 2nd structure of this invention, in the chemical | medical agent vaporization container of the said 1st structure, a triangular-shaped seal extraction part which has a top part toward the inner edge side of a seal | sticker part, and a top part toward an outer edge side By alternately arranging the triangular seal-released portions along the longitudinal direction of the seal portion, the gap between the adjacent seal-release portions is reduced, and breakage is likely to occur. Therefore, it can be easily broken from the outside of the outer container and becomes a weakly sealed portion with stable heat seal strength.

FIG. 1 is a schematic plan view of a chemical evaporation container according to an embodiment of the present invention, and FIG. 2 is a side cross-sectional view of the chemical evaporation container (a cross-sectional view taken along line AA ′ in FIG. 1). A chemical evaporation container 1 shown in FIGS. 1 and 2 includes a resin outer container 2 and an inner packaging bag 3 accommodated in the outer container 2. The storage portion 8 of the inner packaging bag 3 is filled with a liquid or gel-like medicine 4 (here, a fragrance).

  The outer container 2 includes an outer container main body 2a and a lid member 2b, and is integrally formed by heat-sealing flange portions 5 formed on the respective outer edge portions. A window 6 is formed on the lid member 2 b, and the window 6 is sealed with a drug-permeable film 7. As the outer container 2, an injection molded product of a thermoplastic resin such as polypropylene, polyethylene, polyester, polystyrene or the like, or a sheet molded product obtained by vacuum molding or pressure molding of the thermoplastic resin sheet can be used.

  Further, as described later, since the inner packaging bag 3 needs to be pressed and broken from the outside of the outer container 2 during use, the outer container 2 should be formed of a material that can be easily elastically deformed. Is preferred.

The drug permeable film 7 includes a multilayer containing one or more thermoplastic resins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, ionomer resin, ethylene-acrylic acid copolymer, ethylene-α-olefin copolymer. A film can be used, and the oxygen gas permeability is preferably 100 cc / m ² · 24 h · atm or more, more preferably 500 cc / m ² · 24 h · atm or more. In order to heat-seal the outer container body 2a and the lid member 2b, and the lid member 2b and the drug permeable film 7, at least the inner surface of the outer container 2 needs to be made of a heat-sealable material.

  The inner packaging bag 3 has a storage portion 8 sealed in three sides by a side seal portion 9 and an upper seal portion 10, and the upper seal portion 10 is a weak seal portion that can be broken by pressing the inner packaging bag 3. It has become. A detailed configuration of the upper seal portion 10 will be described later.

  FIG. 3 is a partial cross-sectional view showing the laminated structure of the laminated body constituting the inner packaging bag 3. The laminate 11 is configured by sequentially laminating a base material layer 20 that is an outermost layer, a drug blocking film layer 21, and a thermoadhesive resin layer 22 that is an innermost layer. An adhesive layer 23 is laminated between the barrier film layer 21, the drug barrier film layer 21, and the thermal adhesive resin layer 22.

  Since the base material layer 20 becomes a basic material constituting the laminate 11, and further becomes a base material for holding a drug blocking film layer 21 (described later), it can withstand conditions such as formation and processing thereof. In addition, they can be held well without impairing their properties, and, in the manufacture of the package, processing workability, heat resistance, slip resistance, pinhole resistance, water vapor or gas barrier properties, and other various It is preferable that it is excellent in physical properties.

  As the base material layer 20, a stretched film made of a polyamide-based resin, a biaxially stretched nylon film, a biaxially stretched polypropylene film, a biaxially stretched polyester-based resin film, or the like is used. A resin film is particularly preferably used. Specific examples of the stretched film 4 made of the polyamide-based resin include, for example, MXD nylon 6 film, MXD nylon resin and nylon 46, nylon 6, nylon 66, nylon 610, nylon 612, nylon 11, nylon 12, Multi-layer laminated film composed of 2 to 3 or more layers with various polyamide resins such as others, or ethylene-vinyl alcohol copolymer and the above nylon 46, nylon 6, nylon 66, nylon 610, nylon 612, nylon 11 A multilayer laminated film composed of 2 to 3 or more layers with various polyamide resins such as nylon 12 and others can be used. In particular, a multilayer laminated film formed by coextrusion with an ethylene-vinyl alcohol copolymer and the above nylon has a high gas barrier property, and further has an aroma retaining property, transparency, impact resistance, flex pinhole resistance, Since it is excellent in piercing property, flexibility, and chemical resistance, it is more preferable. The film thickness is preferably about 6 to 50 μm. Examples of the multilayer laminated film include a co-extrusion co-stretched film including a nylon resin layer, an ethylene-vinyl alcohol copolymer layer, and a nylon resin layer, and a nylon resin layer, an MXD nylon resin layer, and a nylon resin layer. A co-pressed and co-stretched film or a stretched film made of MXD nylon can be used. The stretched polyamide-based resin film has the advantages that it is excellent in waist, strength, gas barrier properties against oxygen gas, water vapor and the like, impact resistance, flex pinhole resistance, puncture resistance, and the like. In the above, as the ethylene-vinyl alcohol copolymer film, for example, an ethylene content of about 25 to 50 mol% obtained by completely saponifying an ethylene-vinyl acetate copolymer having a vinyl acetate content of about 79 to 92 wt%. The ethylene-vinyl alcohol copolymer can be used. The ethylene-vinyl alcohol copolymer has a high gas barrier property and is excellent in aroma retention and transparency. In the above ethylene-vinyl alcohol copolymer, those having an ethylene content of 50 mol% or more are not preferable because the oxygen gas barrier property is drastically lowered and the transparency is also deteriorated. % Or less is unfavorable because the thin film becomes brittle and the oxygen gas barrier property decreases under high humidity. Specific examples of the biaxially stretched polyester resin film include polyethylene terephthalate resin, polybutylene terephthalate resin, polyethylene-2, 6-naphthalate resin, polybutylene-2, 6-naphthalate, and polycyclohexanedimethylene terephthalate. Various polyester resins such as resins can be used. In addition, a film obtained by depositing an inorganic oxide such as aluminum oxide or silicon oxide on these films, or a film obtained by coating or coextruding a barrier resin such as polyvinyl alcohol or vinylidene chloride on these films can be used. The thickness of the base material layer 5 is usually about 6 to 50 μm.

  The drug-blocking film layer 21 prevents the permeation of the gasified drug 4 by imparting drug blocking properties to the inner packaging bag 3. As the drug blocking film layer 21, a resin such as polyvinylidene chloride resin, polyvinyl alcohol, ethylene-vinyl alcohol copolymer film (EVOH), polyamide resin, polyester resin, or the like is selected and the film is used. It can be used by laminating. In addition, as the material of the drug blocking film layer 21, for example, an aluminum foil or an aluminum vapor deposition film thereof, or a vapor deposition film of a metal oxide such as silicon oxide or aluminum oxide can be provided on the stretched film. As a method of forming a vapor deposition film on a stretched film, for example, a physical vapor deposition method (Physical Vapor Deposition method, PVD method) such as a vacuum vapor deposition method, a sputtering method, an ion plating method, or a plasma chemical vapor deposition method. Examples thereof include chemical vapor deposition methods (Chemical Vapor Deposition method, CVD method) such as a chemical vapor deposition method, a thermal chemical vapor deposition method, and a photochemical vapor deposition method. In the case of forming a silicon oxide vapor deposition film, the vapor deposition film can be formed by plasma chemical vapor deposition using organosiloxane as a raw material. The thickness of the drug blocking film layer 21 is about 9 to 100 μm.

  The heat-adhesive resin layer 22 is not particularly limited as long as it can be melted by heat and can fuse the inner surfaces of the laminate 11 to each other. For example, low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear ( (Linear) Low density polyethylene, ethylene / α-olefin copolymer polymerized using metallocene catalyst (single site catalyst), polypropylene, ethylene / vinyl acetate copolymer, ionomer resin, ethylene-ethyl acrylate copolymer Polyolefin resins such as ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer, ethylene-propylene copolymer, methylpentene polymer, polyethylene or polypropylene, acrylic acid, methacrylic acid, maleic anhydride, fumaric acid, etc. Acid-modified polyolefin tree modified with various unsaturated carboxylic acids It one not selected from the like can be used or two or more.

  As a method for forming the heat-adhesive resin layer 22, a method of laminating the above-mentioned heat-adhesive resin by a melt extrusion method or a method of laminating a heat-adhesive single layer or multilayer film is used. The thickness of the heat-adhesive resin layer 22 is preferably about 10 μm to 100 μm, particularly preferably about 15 μm to 50 μm, considering heat sealability and the like.

  The adhesive layer 23 firmly adheres the base material layer 20, the drug blocking film layer 21, and the thermoadhesive resin layer 22 constituting the laminated body 11 to prevent the occurrence of delamination. . Examples of the adhesive constituting the adhesive layer 23 include a polyvinyl acetate adhesive, a homopolymer such as ethyl acrylate, butyl, 2-ethylhexyl ester, and the like, methyl methacrylate, acrylonitrile, styrene, and the like. Polyacrylic acid ester adhesives, cyanoacrylate adhesives, and ethylene copolymers based on copolymers of ethylene and monomers such as vinyl acetate, ethyl acrylate, acrylic acid, methacrylic acid, etc. Adhesives, cellulose adhesives, polyester adhesives, polyamide adhesives, polyimide adhesives, amino resin adhesives made of urea resin or melamine resin, phenol resin adhesives, epoxy adhesives, polyurethane adhesives Adhesive, reactive (meth) acrylic adhesive, chloroprene rubber, ni Rirugomu, styrene - rubber adhesive comprising a butadiene rubber, a silicone-based adhesive, an alkali metal silicate, may be used an inorganic adhesive or the like made of a low-melting-point glass or the like.

  Instead of the adhesive layer 23, an adhesive resin layer may be laminated. The adhesive resin layer may be any resin that melts by heat and can thermally bond the base material layer 20, the drug blocking film layer 21, and the thermal adhesive resin layer 22 to each other. Similar resins can be used.

  In addition, the laminated structure of the laminated body 11 shown in FIG. 3 is a preferable example, and what is necessary is just a laminated structure including at least the drug blocking film layer 21 and the thermoadhesive resin layer 22 which is the innermost layer. When the specific structure of the laminated body 11 is illustrated, a biaxially stretched polyester film (base material layer) / adhesive layer / EVOH resin layer (drug blocking film layer) / adhesive layer / heat-sealable biaxially stretched polypropylene film (HSOPP; thermal adhesive resin layer) and the like.

  FIG. 4 is a partially enlarged view of the upper seal portion 10 of the inner packaging bag 3. In the upper seal portion 10, a large number of triangular seal release portions 30 are formed along the longitudinal direction of the upper seal portion 10. The adjacent seal-released portions 30 have a triangular top portion 30a facing the inner side of the inner packaging bag 3 (the lower side in FIG. 4) and a triangular base side 30b facing the inner side of the inner packaging bag 3. Are alternately arranged adjacent to each other. Thereby, the upper seal part 10 is set to such an extent that the peel strength is smaller than that of the side seal part 9 and is easily peeled by pressing the inner packaging bag 3 with a finger.

  Next, the usage method of the chemical evaporation container 1 of this invention is demonstrated. When the inner packaging bag 3 is pressed from the outside in a state of being stored in the outer container 2, pressure acts on the upper seal portion 10 via the medicine 4 (here, fragrance) enclosed in the inner packaging bag 3. Since this pressure is concentrated on the inner edge portion 10a of the upper seal portion 10, the seal begins to peel from between the top portion 30a of the seal release portion 30 and the inner edge portion 10a that are closest to the inner edge portion 10a.

  When the pressing force is increased, the peeling is greatly expanded, and the seal release portion 30 communicates with the inside of the inner packaging bag 3. Then, the medicine 4 enclosed in the inner packaging bag 3 flows into the seal release part 30. When the pressing is further continued, the seals between the adjacent seal-released parts 30 and between the bottom part 30b and the outer edge part 9a are peeled off, and the medicine 4 enclosed in the inner packaging bag 3 is put in the outer container 2. leak.

  In this state, the drug evaporation container 1 is installed at a predetermined location, whereby the drug 4 in the outer container 2 is gradually gasified. The gasified drug 4 passes through the drug-permeable film 7 that seals the window 5 of the outer container 2 and evaporates to the outside of the outer container 2.

  In the above embodiment, the weak seal portion is formed by forming the seal removal portion 30 in the entire upper seal portion 10. However, the weak seal portion may be formed by forming the seal removal portion 30 only in a part of the upper seal portion 10. . Further, instead of the upper seal part 10, the seal release part 30 may be formed in the side seal part 9, or the seal release part 30 may be formed in both the side seal part 9 and the upper seal part 10. .

  With the above configuration, the medicine can be evaporated through the medicine-permeable film 7 of the outer container 2 simply by pressing the inner packaging bag 3 from the outside of the outer container 2 with a finger and breaking the upper seal portion 10. Therefore, there is no possibility that the leaked medicine will contaminate the user's hand or surroundings, or the usage time may be shortened due to the reduction of the medicine volume.

  Moreover, since it is possible to reduce the heat seal strength of the upper seal portion 10 using a normal heat adhesive resin, it is not necessary to use a special specification resin with low heat seal strength as the heat adhesive resin layer 22, The manufacturing cost of the chemical evaporation container 1 can also be reduced. Furthermore, since the weak seal portion can be formed at a specific position of the inner packaging bag 3, it can be broken from a specific region of the inner packaging bag 3.

The upper seal portion 10 which is a weak seal portion forms a mesh-like engraving on the surface of the heat seal member (heat seal bar) in accordance with the shape of the seal release portion 30 or embeds a material having low heat conductivity . Thus, it can be formed under the same conditions as the side seal portion 9.

  Here, the lower the peel strength of the upper seal portion 10, the better the openability, but the higher the risk that the drug 4 will leak out due to external pressure. Therefore, it is necessary to set the peel strength in accordance with the pressure resistance required for the inner packaging bag 3 and the openability. The peel strength of the upper seal part 10 can be adjusted by the shape of the seal release part 30, the distance between adjacent seal release parts 30, and the distance between the seal release part 30 and the inner edge part 10a or the outer edge part 10b of the upper seal part 10. is there. For example, as shown in FIG. 4, if the seal release portion 30 with the triangular top portion 30 a facing the inside of the inner packaging bag 3 is formed, the peel strength of the top portion 30 a is reduced. Openability can be further improved. The peel strength of the upper seal part 10 is preferably about 3 N / 15 mm.

  Next, the manufacturing method of the chemical evaporation container of this invention is demonstrated. First, the drug blocking film layer 21 is laminated on the base material layer 20 via the adhesive layer 23, and then the thermal adhesive resin layer 22 is laminated via the adhesive layer 23 to manufacture the laminate 11.

  Next, the inner surface (the surface on the side of the thermal adhesive resin layer 22) of the laminated body 11 is overlapped facing each other, two sides are heat-sealed to form the side seal portion 9, and then a predetermined amount of the medicine 4 is filled. Then, the remaining one side is heat-sealed to form the upper seal portion 10, thereby forming the inner packaging bag 3. At this time, the seal removal part 30 is formed in the upper seal part 10. As a heat sealing method, for example, a known method such as a bar seal, a rotary roll seal, a belt seal, an impulse seal, a high frequency seal, or an ultrasonic seal can be used.

  The inner packaging bag 3 used in the present invention can be manufactured continuously or batchwise. For example, in the case of continuous production, two long laminated bodies 11 wound in a roll shape are sequentially fed out, and the process of filling the medicine 4 at the same time as heat-sealing around both laminated bodies 10 is continuously performed. Thus, a long intermediate body in which a plurality of inner packaging bags 3 in which the medicine 4 is encapsulated is arranged in a matrix is manufactured. Thereafter, the intermediate body is cut in the longitudinal direction by a slitter, and further cut in the width direction by a predetermined number to form individual inner packaging bags 3.

  Moreover, when manufacturing in batch type, two laminated bodies 10 are overlap | superposed, the thermoadhesive resin layer 22 is made to oppose, and also the periphery edge part is side seal type, a two-side seal type, a three-side seal type, a four-side seal, for example Various types of inner packaging bags 3 can be manufactured by heat sealing according to a heat sealing form such as a mold.

  Furthermore, it is possible to manufacture the inner packaging bag 3 with only one laminate 11. That is, the laminated body 11 is bent to form a weakly sealed portion at least partially by a seal removing portion 30 according to a heat seal form such as a two-side seal type, a three-side seal type, an envelope-attached seal type, or a palm-attached seal type (pillow seal type). What is necessary is just to manufacture the inner packaging bag 3 in which is formed.

Finally, the inner packaging bag 3 in which the medicine 4 is sealed is stored in the outer container body 2a, and the flange portion 5 is heat-sealed by covering the lid member 2b on which the medicine-permeable film 7 is attached. A transpiration container 1 is manufactured.

  The thus obtained chemical transpiration container 1 of the present invention has excellent characteristics such as easy opening, transpiration of contents, manufacturability, etc. as a packaging material for liquid or gel-like fragrances, deodorants, insect repellents and the like. Therefore, it is possible to provide a chemical evaporation container with significantly improved usability and manufacturing cost.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the above embodiment, the drug permeable film 7 is attached to the window portion 5 of the resin-molded outer container 2, but the entire outer container 2 may be formed of the drug permeable film.

  Further, the above production method is only a preferred example. For example, as a production method of the laminate 11, a lamination method used when producing an ordinary packaging material, for example, a wet lamination method, a solvent-free lamination method, a coextrusion lamination, or the like. The method, the inflation method, and other methods can also be used.

  Further, when the above layers are laminated, if necessary, pretreatment such as corona discharge treatment, ozone treatment, flame treatment, blast treatment, etc. can be optionally applied to the surface of the substrate to be laminated. Hereinafter, the configuration of the present invention will be described more specifically using examples.

  A biaxially stretched polyethylene terephthalate film having a thickness of 12 μm is used as the base material layer 20, and an EVOH film having a thickness of 12 μm is used as the drug blocking film layer 21 on the surface of the base material layer 20, and polyurethane as an adhesive layer. Lamination was performed via a system adhesive. Further, a laminate 11 was manufactured by laminating a 30 μm thick HSOPP film as the heat-adhesive resin layer 22 on the EVOH film side surface through a polyurethane adhesive as an adhesive layer.

  Next, using the two laminates 11 manufactured as described above, both the heat-adhesive resin layers 22 face each other so as to be the inner surface, and a triangular seal-out portion 30 as shown in FIG. The sealing strength was compared using the inner packaging bag 3 in which a large number of the inner packaging bags 10 were formed along the longitudinal direction of the upper seal portion 10 as a comparative example. In addition, the space | interval from the triangular top part 30a of the seal | sticker extraction part 30 in this invention to the inner edge part 10a of the upper seal part 10 was 2.0 mm.

  The sealing strength was measured by measuring the strength when two laminates 11 each having a width of 25 mm were heat sealed and peeled at a pulling speed of 300 mm / min using an autograph (manufactured by Shimadzu Corporation) (n = 20). All the heat sealing conditions were a sealing temperature of 150 ° C., a sealing pressure of 1 kg, and a sealing time of 1 second. The results are shown in Table 1.

  As apparent from Table 1, the inner packaging bag 3 of the present invention in which the upper seal portion 10 is provided with the seal release portion 30 has a peel strength of 6.7 N / 25 mm width (≈4 N / 15 mm width), and the upper seal. Compared with the inner packaging bag 3 (8.6 N / 25 mm width) of the comparative example in which the part 10 was a normal heat seal, the peel strength could be reduced to about 3/4.

  This inner packaging bag 3 was filled with a gel-like fragrance and stored in an outer container 2 made of resin as shown in FIGS. When the inner packaging bag 3 was pressed from the outside of the outer container 2 with a finger, the inner packaging bag 3 could be easily broken and used.

  INDUSTRIAL APPLICABILITY The present invention is used for a chemical transpiration container that packs transpirational drugs such as fragrances, deodorants and insect repellents, prevents transpiration of the drug during storage, and evaporates to the outside through a drug permeable film during use. Is possible. By utilizing the present invention, since it has excellent characteristics such as easy opening, transpiration of contents, and manufacturability, it is possible to provide a chemical transpiration container with significantly improved usability and production cost.
