Description

  The present invention relates to an outer packaging box for a steam release packaging bag applied to an outer packaging of a steam release packaging bag in which cooked food such as retort food is hermetically sealed so that microwave heating is possible. Specifically, when the packaging bag is cooked and cooked with steam holes that are peeled open by an internal pressure of gas such as water vapor generated by heating the packaging microwave oven, the packaging bag is filled with steam. The present invention relates to an outer packaging box for a steam release packaging bag in which stored items are not scattered in a microwave oven.

  Conventionally, many foods and the like are packed in air-tight and liquid-tight packaging bags made of laminated films such as synthetic resins and are distributed as sealed packaged foods.

  Some of the sealed packaged foods are shipped after being cooked in a sealed package. In addition, in order to prevent spoilage, alteration, discoloration, taste change, etc. due to germs that may be mixed in the sealed packaged food until it is manufactured, stored, distributed, and eaten, The product may be shipped after being subjected to heat sterilization or heat / pressure sterilization in a state.

  Thus, the sealed packaged food is often subjected to heating, heat sterilization, heat pressure sterilization or the like before shipment. And when a general consumer eats this, even such a sealed packaged food is often heated in a microwave oven or the like.

  The microwave oven vibrates water molecules contained in food by high-frequency (ultra-high frequency) irradiation, and heats the food with frictional heat generated by the vibration of the water molecules.

  Water vapor is generated along with the high-frequency heating by the microwave oven, and the normal sealed bag formed of the plastic film expands and bursts due to the water vapor.

  For this reason, in order to avoid the bursting of the sealed packaging food packaging bag due to an increase in the internal vapor pressure during heating, the packaging bag is opened and the stored item is put in another container and heated in that container. There are things to do.

  Further, in a state of opening the packaging bag stored in the outer box, the food packaging body is heated with the opening opening facing upward so that the stored item does not spill with the packaging bag using the stored outer box. A microwave heating method (see, for example, Patent Document 1) is known.

  In this microwave heating method of a food packaging body, as shown in FIG. 15, a self-standing means 101 is provided from a component of the packaging box 100 in a packaging box 100 that houses a heat-resistant storage bag body 103. The self-supporting means 101 is separated from the packaging box, and the packaging box is attached to the self-supporting means 101. Then, the heat-resistant storage bag 103 is placed in the standing packaging box 100 to be self-supporting, and heated by being irradiated with microwaves.

  In addition, recently, due to the development of food processing technology and packaging technology and the spread of microwave ovens, etc., a packaging bag containing cooked foods that can be heated in a microwave oven that does not need to be opened unnecessarily when heating is proposed, It has been put into practical use.

  The cooked food-containing packaging bag capable of heating in the microwave oven is provided with a steam escape portion that opens when the internal vapor pressure rises above a predetermined pressure. And it can heat without opening.

  The cooked food-containing packaging bag capable of heating in the microwave oven is provided with a steam escape portion that opens when the internal vapor pressure rises above a predetermined pressure.

  For example, in order to discharge water vapor generated inside the bag by high-frequency heating of a microwave oven to the outside of the bag, a part of the pouch body is opened during heating, or an escape hole is provided in the pouch body.

  Also, make a water vapor adjustment hole and seal this water vapor adjustment hole with an adhesive seal, and peel off the seal before heating, or if the steam pressure in the pouch body increases by heating, the seal part will open easily Whether the valve is opened or not.

  On the other hand, the wrapping bag containing cooked food is made of paper for convenient storage, transportation, display, etc., and for displaying decoration, explanation of food, eating method, etc. at the distribution stage to consumers. It is often packed in a uniform packaging box.

  Many of the packaging boxes have flattened packaging bags containing cooked foods. In general, many flat rectangular parallelepiped shapes are observed.

  Furthermore, the microwave oven heating package which heats a microwave oven without taking out this packaging bag from the packaging box made from paper etc. in which the packaging bag containing the cooked food which can be heated with a microwave oven is accommodated (for example, refer patent document 2). ) And hermetically packaged food packages and hermetically packaged foods packaged in a packaging box (see, for example, Patent Document 3) are also known.

  As shown in FIG. 16, the microwave oven package is a microwave oven package 200 provided with an exterior box 113 applied to the outer packaging of a packaging bag 112 filled with cooked food. And when it heats, the part for relief pressure which relieves the internal pressure of the packaging bag 112 is formed in the part which sticks back.

  And when heating the microwave heating package 200, the separation opening part 114 for exposing the back sticking part from the exterior box 113 is formed.

  In addition, as shown in FIG. 17, a package box 300 of sealed packaged food and a package box 300 of sealed packaged food packaged in a package box are packaged by packaging the food in a package bag 121 provided with a steam escape portion as shown in FIG. Housed in a box 122. And when heating with a microwave oven, in order to expose a vapor escape part, as shown in FIG. 18, the part from the front wall 116 of the top wall 115 is opened.

  It has been pointed out that heating the entire box in this way reduces the risk of burns when taken out from the microwave oven.

  When the blank boards 10 and 90 are paperboards, for example, ordinary paperboards such as ivory paper, postcards, double-sided card papers, Manila cardboards, white paperboards that are white balls can be used.

  Also, depending on the contents to be stored, distribution / use conditions or use, paper with used paper as the intermediate layer of paper, or lower grade paper such as yellow balls, chip balls, colored balls (double-sided craft balls, single-sided craft balls, etc.) It can also be used.

  In addition, when cosmetics are required for the outer packaging box for the steam release packaging bag of the present invention, printing processing, foil pressing processing, flocking processing or uplifting processing (uplifting processing using foaming resin ink or male and female molds) Embossing).

  In addition, the printing applied to the front side of the paperboard is a printing method such as letterpress printing, offset printing or gravure printing, flexographic printing or screen printing, etc. Display that contributes to the purchase motivation.

  Then, a printing method is appropriately selected depending on the production quantity (lot) or application of the paperboard to be printed, the design, the surface material to be printed, and the like. Furthermore, surface processing for protecting the printed surface subjected to the printing process according to distribution conditions or over-the-counter sales conditions is also performed.

  The ink for offset printing uses a vehicle that combines synthetic resin, drying oil, and high-boiling solvent, and the composition is adjusted according to various conditions such as gloss, friction resistance, setability, and drying time. A known ink is used in consideration of interfacial suitability related to the balance with the plate surface with water.

  For example, when the ink is an oil-based ink type (referring to an ink mainly composed of an oxidation polymerization type drying oil), a synthetic resin, a drying oil (vegetable oil), a solvent, an auxiliary agent and the like are required as a vehicle.

  Usually, rosin-modified phenol, petroleum resin, alkyd resin, or the like is used as the synthetic resin. In addition, as the drying oil, linseed oil, drill oil, soybean oil, synthetic drying oil and the like are used. Further, a high boiling point petroleum solvent or the like is used as the solvent.

  Further, as the auxiliary agent, a compound or the like is used as a viscosity adjusting agent, and a drying agent (dryer) or a drying inhibitor is used as a drying adjusting agent.

In the case of the gravure printing method, an organic solvent type ink type is used. For example, polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polyvinyl butyral, polymethyl is used as the resin in which the gloss material is dispersed. A thermoplastic polymer resin such as methacrylic, polyurethane, polyester, polyamide, nitrocellulose, or cellulose derivative, or a thermosetting polymer resin such as melamine or urea can be used. And it selects from these suitably.

  Furthermore, the organic solvent for dissolving the resin is not particularly limited as long as the resin can be dissolved or dispersed. For example, esters such as ethyl acetate and butyl acetate, methyl ethyl ketone, methyl isobutyl Among the ketones such as ketones, aromatic hydrocarbons such as toluene and xylene may be used alone or arbitrarily blended.

  Furthermore, in order to make the printed surface more beautiful and beautiful, the gloss overprint varnish or the front side of the paperboard is printed on, for example, polyethylene (PE) or polypropylene (PP) or polyethylene terephthalate (PET). A resin such as polyimide (PI), polyacrylonitrile (PAN), polyvinyl chloride (PVC), etc. is laminated.

  For the lamination, an extrusion coating process in which the film is melted by heat or a lamination process in which a film is bonded is used. And the gloss and gloss of the printed surface can be increased.

  Also, a resin dissolved resin such as vinyl acetate or vinylidene chloride is coated with a rubber roll, and then press-coated by heat-pressing the endless steel belt for a certain period of time, or a vinyl chloride film or polypropylene film of about 0.015 to 0.02. Is applied to a paper board on which printing has been performed, and then is performed by a film sticking press process in which a roll or a flat plate heat press is applied.

  In addition, embossing (embossing or embossing) for imparting cosmetics to the surface of the paperboard is a flat pressure type, circular pressure type or rotary type that produces a blank board having a predetermined ruled line (crease line) and shape from the paperboard. It can also be performed on a punching machine such as a punching ruler.

  Moreover, it can also apply on the foil stamping machine which performs foil stamping. Furthermore, embossing can be performed simultaneously with foil stamping on a foil stamping machine.

  Moreover, the paperboard for producing the blank boards 10 and 90 is given water resistance, oil resistance, chemical resistance, etc. depending on conditions used, for example, storage method, storage period, contents, distribution conditions, store sales conditions, and the like. The

  There are a method of imparting water resistance, oil resistance, chemical resistance, etc. to the paperboard, including a method of imparting at the time of paperboard processing and a method of imparting after the papermaking processing. For example, one of the methods is appropriately selected depending on the storage method, the storage period, the contents, the distribution conditions, the over-the-counter sales conditions, and the like.

  When water resistance is imparted to the paperboard at the time of papermaking, for example, the added waterproofing agent is usually an internally added waterproofing agent that is internally added to the pulp suspension before papermaking.

  Examples of wet paper strength enhancers include urea-formaldehyde resin, melamine-formaldehyde resin, epoxidized polyamide resin, polyethyleneimine resin, dialdehyde starch, and glyoxalized polyacrylamide resin.

  The amount of the water-resistant agent added varies depending on the type of pulp to be used, the type of chemical, and the intended water resistance.

  In addition, as secondary processing chemicals that impart water resistance to paperboards that have been processed, waxes such as carnauba wax, paraffin wax, polyethylene wax, etc., which have an excellent balance in price or performance, are often used. .

  Further, a polymer solution or emulsion such as polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, ethylene-vinyl acetate copolymer, vinylidene chloride-vinyl acetate copolymer insoluble in water is used.

  Also, roll paper coaters, air knife coaters, metering bar coaters, fountain blade coaters, bevel blade coaters, short dwell coaters, curtain coaters, etc. are used for processing water-resistant or chemical-resistant agents on the paperboard processed above. it can.

  And although it does not specifically limit, a water-resistant agent, a chemical-resistant agent, etc. are applied to the front side surface or back side surface or both side surfaces of the paperboard using any appropriate coating machine.

  In order to impart oil resistance to paperboard, it is usually necessary to make the sea surface tension of the processed surface smaller than the surface tension of the oily substance.

  A chemical having such a function is referred to as an oil-resistant agent, and a fluorine-based oil-resistant paper is generally used, as known as oil-resistant paper, mainly using a fluorine compound such as a perfluorinated hydrogen acrylate or phosphate ester. It is treated with an agent.

  In addition, when applying the oil proofing agent to the paperboard that has been processed, the roll coater, the air knife coater, the metering bar coater, the fountain blade coater, the bevel blade coater, the short dwell coater, the curtain coater and the like are not particularly limited. Using the appropriate coating machine, it is applied to the front side, back side or both sides of the paperboard.

  Further, by forming a resin layer on the inner surface of the paperboard to which water resistance or oil resistance is imparted, functionality such as water resistance or oil resistance can be further improved.

  The resin layer is formed by, for example, polyethylene (PE), low density polyethylene (LDPE), high density polyethylene (HDPE), polyvinyl chloride (PVC), polyfluorinated ethylene (PTFE), polyvinylidene chloride (PVDC), polycarbonate. (PC), nylon 6 (NY), polybutylene terephthalate (PBT), polypropylene (PP), polyethylene terephthalate (PET), acrylonitrile (AN), linear low density polyethylene (LLDPE), polyacrylonitrile (PAN), impact resistance Resins such as reactive polystyrene (HIPS) and polyacrylonitrile (PAN) can be used.

  Further, the resin layer applied to the inner surface of the paperboard is applied by either an extrusion coating process in which a thermoplastic resin or the like is melted and applied, or a lamination process in which a film is bonded.

  Examples of the laminating process include wet laminating, dry laminating, non-solvent laminating, knee laminating, and extrusion laminating. Then, an appropriate laminating method is selected.

Next, the steam release packaging bag 50 accommodated in the outer box 60, 90 for the steam release packaging bag of the present invention,
80 is a packaging bag in which cooked or semi-cooked food is sealed, and a gas such as water vapor inside the package that is pressurized with heating in a cooking device such as a microwave oven is formed in the packaging bag. It can escape smoothly by the steam venting means.

  Steam-wrapped packaging bags are produced and used in large quantities due to the development of food processing technology and packaging technology, the spread of microwave ovens, and the like.

  Water vapor is generated along with the high-frequency heating by the microwave oven, and the normal sealed bag formed of the plastic film expands and bursts due to the water vapor.

  Therefore, in a conventional microwave oven pouch, in order to discharge water vapor generated inside the bag by high-frequency heating of the microwave oven to the outside of the bag, a part of the pouch body is opened during heating, or an escape hole is provided in the pouch body. ing.

  As the steam release packaging bags 50 and 80 accommodated in the outer packaging boxes 60 and 90 for steam release packaging bags of the present invention, for example, packaging bags as shown in FIGS. 9A and 9B are used.

  As shown in FIGS. 9 (a), 9 (b) and 10, the steam release packaging bags 50 and 80 are formed by superimposing a front side laminated film 61 and a back side laminated film 62, which are laminated films, respectively.

  Then, as shown in FIGS. 9A and 9B and FIG. 10, the periphery of the end portion is heat-sealed by heat sealing with the heat-adhesive sealant layers 63 and 64 laminated on the overlapped inner surface. Thus, a bottom seal portion 65 and side seal portions 66 on both sides are formed. Then, storage items such as a liquid material, a solid material, and a solid-liquid mixture can be stored from the opening 68.

  On the back side laminated film 62, a V-shaped folded portion end 69 is formed on the back side laminated film 62 in parallel with the bottom seal portion 65 on the side of the bottom seal portion 65 over the entire width of the steam release packaging bag. Yes.

  Further, an outer folded portion 72 and an inner folded portion 71 are formed at the end of the folded portion. And inside the outer folding | returning part 72 and the inner side folding | returning part 71, the peelable tape material 67 which has easy peelability is inserted over the whole breadth of the steam release packaging bag in parallel with the folding | returning part edge part.

  Moreover, the peelable tape material 67 (shown in FIG. 14) is formed on the adhesive resin layer 73 exhibiting adhesiveness to the sealant layers 63 and 64 of the front side and back side laminated films 61 and 62, and the sealant layers 63 and 64. On the other hand, a peelable tape material 67 is formed from a two-layer structure of a peelable resin layer 74 that exhibits peelability due to vapor pressure.

  And it is heat-sealed by the center pattern seal | sticker part 75 of reverse concave shape, the right-and-left pattern seal parts 76 and 77, and the side seal parts 66 and 66, and interposes.

  Moreover, the upper end part area | region of the peelable tape material 67 is extended long upwards rather than the inner side folding | returning part 71 folded in V shape, as shown in FIG. And the upper region (upper side of the drawing) of the peelable tape material 67 which is the extended portion is the back side laminated layer outside the outer folded portion 72 of the back side laminated film 62 facing the adhesive resin layer surface of the upper end region. The sealant layer 64 on the inner surface of the film 62 is heat sealed.

And it adheres in a state where peeling by vapor pressure is impossible, and the lower region (the lower side of the drawing) region of the peelable tape material 67 is heat sealed against the sealant layer surface of the inner surface of the back side laminated film facing it. In addition, the center pattern seal portion having an inverted concave shape and the unsealed portions of the left and right pattern seal portions are not bonded.

  9A, 9B, and 10, the lower end region of the peelable tape material 67 is a seal provided inside the unsealed portion of the central seal portion 75. The sealant layer 64 of the back side laminated film 62 on the inner surface of the portion 78 is heat sealed.

  In this way, the adhesive resin layer surface of the peelable tape material 67 is heat-sealed so that it cannot be peeled off by the vapor pressure on the sealant layer 64 on the inner surface of the back side laminated film 62 on the outer side of the V-shaped folded portion 71 of the inner folded portion 71. Has been.

  And the peelable resin layer surface of the peelable tape material 67 is heat-sealed to the sealant layer 64 on the inner surface of the back side laminated film 62 inside the V-shaped folded back of the inner folded portion so as to be peelable by vapor pressure.

  In addition, in the unsealed portion 81 region of the central pattern seal portion 75 of the steam release packaging bag, the back side laminated film 62 of the outer folded portion 72 and the peelable tape material 67 on the inner surface of the outer folded portion 72, A reverse vent-shaped cut-out line steam vent hole 22 is provided therethrough.

  Since the shape of the steam release hole 22 is a reverse concave shape having a short straight line that is oblique or vertically downward at both ends of a straight line parallel to the straight line of the outer folded end, the opening diameter is three-dimensional. It has a structure in which water vapor is smoothly discharged.

  Further, the steam vent hole 22 of the steam vent packaging bag is sealed and sealed by the central pattern seal portion 75 at room temperature (normal atmosphere) before filling the contents into the packaging bag and after filling and sealing and packaging. Yes.

  Then, as shown in FIG. 11 or FIG. 12, in the heating chamber of a heating means such as a microwave oven, the steam release packaging bag is horizontally mounted with the outer folded portion 72 side as the upper surface while being stored in the steam release packaging bag outer box. By placing and heating, the internal pressure such as atmospheric pressure and vapor pressure in the vapor vent packaging bag is increased, and the vapor vent packaging bag is inflated to generate an expansion force.

  Due to the expansion force, the central pattern seal portion 75 undergoes seal peeling and retreat, and the surface of the outer folded portion 72 of the back side laminated film 62 and the surface of the peelable resin layer 74 of the peelable tape material 67 are peeled off. The inside of the packaging bag, the unsealed part, and the outside communicate with each other. Then, the opening diameter is expanded three-dimensionally, the heated steam or gas in the expanded packaging bag is released from the steam vent hole 22, and the contents are heated or cooked without rupturing the packaging bag. It is something that can be done.

  Further, even if the steam vent packaging bag has the outer folded portion of the packaging bag, that is, the steam vent hole 22 on the lower side, the film ends on both sides sandwiching the cut line through which the steam vent hole 22 extends. It is a steam vent packaging bag having a structure in which the edges are hermetically sealed to be in a closed state, and the contents are difficult to leak from the steam vent hole 22 portion, and the contents have a check effect.

  As the peelable tape material 67, for example, as shown in FIG. 14, an adhesive resin layer 73 showing adhesiveness to the sealant layer on the inner surface of the packaging bag and a vapor pressure of steam generated by heating the packaging bag. The tape material etc. which consist of two layers with the peelable resin layer 74 which shows easy peelability can be mentioned.

As the adhesive resin layer 73 exhibiting adhesiveness to the sealant layer on the inner surface of the packaging bag, the heat-sealable adhesive thermoplastic resin constituting the inner surface sealant layer of the laminated films 1 and 2 described above is used as it is. A layer made of a propylene-based polymer (copolymer or terpopolymer) called CPP or a linear low-density polyethylene called LLDPE or LLD is preferably used. And the thickness is often set to 20 to 150 μm. The laminated films 61 and 62 constituting the vapor vent packaging bags 50 and 80 are constituted by laminating at least a base film layer and a sealant layer.

  The base film layer is a layer that serves as a base material for a steam-free packaging bag, and is a sheet or film, such as polyolefin (polyethylene, polypropylene, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate). A relatively heat-resistant plastic film or sheet that is usually used as a packaging material, such as phthalate), polyamide (nylon-6, nylon-66, polyimide, etc.), or a copolymer of these polymers can be used.

  Moreover, a printing layer (not shown) can be formed in the surface or back surface of a base film layer as needed.

  In the same way as when printing on general plastic film bags, the printing layer is designed to improve the sales promotion effect of products on the inner surface of the base film layer, taking into account the friction resistance and weather resistance of the ink. It is preferable to provide a printing layer with a beautiful pattern.

  The heat seal layers 63 and 64 are provided as adhesive layers when forming the packaging bag or the like. Any resin that has heat-fusibility can be used. For example, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, ethylene-methacrylic acid copolymer, ethylene-methacrylic acid ester copolymer, ethylene-acrylic. Resins such as acid copolymers, ethylene-acrylic acid ester copolymers, and metal cross-linked products thereof are used. In consideration of retort sterilization suitability in food packaging, polypropylene resin can be used more preferably.

  And although thickness is decided according to the objective, generally it is the range of 15-200 micrometers. Moreover, as a forming method, it is common to use a dry laminating method or the like in which a film-like material made of the above resin is bonded using an adhesive such as a two-component curable urethane resin. Can be stacked.

  Moreover, when it is necessary to improve the drop strength, puncture strength, and gas barrier properties of the packaging bag, an intermediate layer can be interposed between the base film layer and the sealant layer.

  Furthermore, when a gas barrier property is required for the steam-release packaging bag, for example, a gas barrier laminated film as shown in FIG. 13 can be used. And 95 of the lamination | stacking film | membrane 61 (62) shown in FIG. 13 is a gas barrier lamination film layer. The base 91 in the gas barrier laminated film 95 is a film made of a plastic material.

  A primer layer 92 made of a composite of trifunctional organosilane, acrylic polyol, isocyanate compound, etc., a vapor-deposited thin film layer 93 made of an inorganic oxide having a thickness of 5 to 300 nm, and a gas barrier coating layer 94 are sequentially laminated thereon. ing.
