Description

  The present invention is a retort pouch for storing a liquid seasoning liquid such as hot pot soup and a container for use on a table. The present invention relates to a retort pouch having a shape suitable for using a seasoning liquid on a table during a meal. Moreover, it is related with the seasoning liquid with which the retort pouch was filled.

  As a container for providing a liquid content, a standing retort pouch container called a standing pouch is generally used. Moreover, in order to provide refill goods, such as a liquid detergent, the refill container which made various means to the spout has been proposed (refer patent documents 1-5 etc.). This is because liquid detergent etc. cannot be refilled well because the mouth of the bottle to be refilled is small and spills with a simple bag-like pouch.

Patent Document 6 describes that the contents of high viscosity can be smoothly poured out by providing a constriction on the side surface of the pouch. Patent Document 7 describes that a stable shape can be obtained without causing wrinkles or the like when the contents are filled by inflating the central portions of the heat seals on both sides of the pouch inwardly. Patent Documents 8 to 10 and the like describe a pouch having an upper part made narrower than a bottom part.

  The inventors examined a container suitable for providing a seasoning liquid such as hot pot soup. Pre-seasoned hot pot soup is now in increasing demand because anyone can easily enjoy authentic hot pot dishes simply by preparing ingredients. It is usually provided as a square shaped retort pouch or a standing pouch. However, these retort pouches are only used as storage containers for liquid contents, and only have a shape that assumes that the entire amount is transferred to a pan or the like when used.

  In recent years, various refill containers such as detergents have been devised to reduce the burden on the environment. They are also designed on the assumption that the entire amount can be transferred to a specific container.

  When using the whole amount of hot pot soup in a pan at once, these shapes of pouches are sufficient. When it becomes less or thinner, it may be used by adding one after another. In that case, it is important to be able to pour as much as you like, and that the pouch containing the remaining seasoning liquid will be stable and not fall down. Nabetsuyu is a large-sized pouch with a low-viscosity water-like property and a volume of 500 ml or more unlike detergents. Furthermore, the pouch for hot pot soup is not for refilling, but is a product itself, so its appearance when placed in a store is important. Like many packages of processed foods, the surface of the food package is often printed with a cooked example of the food, and whether the cooked example looks delicious will affect sales.

  Therefore, there is a need different from the device used for refilling containers such as detergents, and a pouch in a form suitable for it is required.

  In view of such a need, the present invention can quickly pour the entire amount at the time of pouring into a pan or the like, and can also pour while adjusting a desired amount, and is placed on the table after opening. It is an object of the present invention to provide a retort pouch having a structure that is stable even at times and hardly spills, and has a good appearance, such as a condiment such as hot pot soup.

  The retort pouch for seasoning liquid according to the present invention has a gusset portion in which the bottom portion of the bag is inserted between the front and rear surface portions of the wall film by folding the bottom film inward and sealing the peripheral portion by heat sealing. In the bag formed by heat-sealing the edge portions on both sides of the wall film of the front and rear two wall surfaces with the side seal portion, the lower gusset portion gives the self-supporting shape. The seal pattern is heat sealed, and a pour-out portion for pour out contents is provided at one corner of the upper portion of the bag.

  Thereby, it becomes a pouch suitable for using the seasoning liquid in a required amount on the table.

  The retort pouch for seasoning liquid according to the present invention has a gusset portion in which the bottom portion of the bag is inserted between the front and rear surface portions of the wall film by folding the bottom film inward and sealing the peripheral portion by heat sealing. In the bag formed by heat-sealing the edge portions on both sides of the wall film of the front and rear two wall surfaces with the side seal portion, the lower gusset portion gives the self-supporting shape. The bag is heat-sealed, and both sides of the bag are provided with an arcuate recess in the vicinity of the middle portion in the length direction of the bag, and a pouch for pouring the contents at one corner of the upper portion of the bag. It is characterized in that an exit is provided.

  As a result, it becomes a shape suitable for pouring out the required amount of the seasoning liquid, and a bow-shaped concave portion is provided on the side portion, so that it is difficult to be in a so-called waist-folded state. There is no worry about the contents spilling when placed on the table, especially because the waist does not break below the recessed part. Also, the overall shape is more stable due to the indentation.

  In addition, when the contents are placed in the pouch, the central part of the wall film becomes slightly convex outward and the cooking example printed on the wall film is provided. Will come out and appeal as the appearance of the product. The center part of the wall film is slightly dented when it is self-supporting if it is straight without providing a dent on the side, so it does not look good.

  The pouring part provided at one corner of the upper part of the retort pouch for seasoning liquid of the present invention is suitably a pouring part that is cut out in a V shape at the upper part of the wall film and heat sealed. Yes. Seasoning liquids are usually not high in viscosity and are not very difficult to dispense. Moreover, since the partner to inject | pour is a thing with wide mouths, such as a pot, the shape of a spout is not ask | required. It is enough that the mouth is narrow enough. Any of the spouts used in detergent refill containers can be applied. However, it must be resistant to retort processing. The pouring portion provided by heat-sealing a V-shaped cutout on the upper surface of the wall film is most suitable because no extra parts are required and the manufacturing process is simple.

  The retort pouch for seasoning liquid of the present invention is preferably one in which an opening means is provided in the pouring part provided in one upper corner and / or the remaining seal part in the upper part. When pouring little by little, the part of the unsealing means of the pouring part is opened and used, and when using the whole amount at once, it can be poured quickly by unsealing from a large unsealing means other than the pouring part. Therefore, the aspect which provided the opening means in both is the most preferable. The position where the unsealing means for the dispensing part is provided is preferably lower than the position where the unsealing means for the remaining upper seal part is provided. After unsealing both unsealing means, the liquid is less likely to spill from the larger mouth when poured out from the dispensing section.

  In the retort pouch for seasoning liquid of the present invention, it is preferable that the position of the arch-shaped concave portions provided on both sides of the bag is around the position of the liquid level of the contents when the contents are filled and self-supported. When the retort pouch is used as it is on the dining table, the film material is small, so there is a problem that the contents are spilled due to a so-called waist-folded state. When the retort pouch is filled with the contents to be self-supporting, the liquid level of the contents is generally at the center position. If there is an arcuate recess on the side, there is no worry of being folded below that position.

  The retort pouch for seasoning liquid of the present invention is particularly suitable for a volume of 500 ml or more. This is because a large capacity tends to cause a problem of hip breakage, and the entire amount is often not used at once.

  The present invention is a seasoning liquid filled in a retort pouch having the above characteristics, preferably a hot pot soup. Non-concentrated seasonings are superior to concentrated types in terms of aroma and taste. However, it tends to be bulky and heavy when bottled. The seasoning liquid filled in the retort pouch having the above characteristics is easy to use and is suitable for any of the production, distribution, sales and use situations.

  The present invention can quickly pour the entire amount at the time of pouring into a pan or the like, and can be poured while adjusting the desired amount, and is a structure that is stable and resistant to spilling even when placed on a table after opening It is possible to provide a retort pouch that can be used on a condiment table such as hot pot soup that has a good appearance such as a cooking example as a product.

  In the present invention, the material constituting the retort pouch according to the present invention will be described. First, the heat-resistant base film according to the present invention is a basic material constituting the retort pouch according to the present invention, and is used for retort processing. Resin film or sheet having excellent properties in mechanical, physical, chemical, etc. can be used because it can withstand, specifically, polyester resin, polyamide resin, etc. Further, a tough resin film or sheet such as a polyaramid resin, a polycarbonate resin, a fluorine resin, or the like can be used. Thus, as the resin film or sheet, any of an unstretched film or a stretched film stretched in a uniaxial direction or a biaxial direction can be used. In the present invention, the thickness of the resin film or sheet may be any thickness as long as it has heat resistance and can be held to the minimum necessary for strength, rigidity, etc., and is about 10 μm to 50 μm. Preferably, about 12 μm to 25 μm is the most desirable.

  Next, in the present invention, a gas barrier film will be described. As such a film, a material having a property of shielding light such as sunlight or a property of not transmitting water vapor, water, gas, or the like may be used. This may be a single substrate or a composite substrate formed by combining two or more substrates. Specifically, for example, an aluminum foil having a light-shielding property and a barrier property or a resin film having a vapor-deposited film thereof, a resin film having a vapor-deposited film of an inorganic oxide such as silicon oxide or aluminum oxide having a barrier property. Films or sheets of resin such as high-density polyethylene having barrier properties such as water vapor, water, and resins such as polyvinylidene chloride, polyvinyl alcohol, saponified ethylene-vinyl acetate copolymer having gas barrier properties Films or sheets of the above, and various color resin films or sheets having a light-shielding property formed by adding a colorant such as a pigment to the resin and kneading the desired additive to form a film are used. be able to. These materials can be used alone or in combination. The thickness of the film or sheet is arbitrary, but is usually about 5 μm to 300 μm, more preferably about 10 μm to 100 μm. Further, in the above, the aluminum foil having a thickness of about 5 μm to 30 μm can be used, and the deposited film of aluminum or inorganic oxide can be about 100 mm to 2000 mm. Examples of the resin film that supports the vapor-deposited film include a polyester film, a polyamide film, a polyolefin film, a polyvinyl chloride film, a polycarbonate film, a polyvinylidene chloride film, a polyvinyl alcohol film, and ethylene-acetic acid. A vinyl copolymer saponified film, etc. can be used.

  Next, in the present invention, a heat-sealable film will be described. As such a film, it can withstand retort processing and further melted by heat, and specifically, for example, medium density polyethylene, high density A film or sheet of a resin such as polyethylene, linear low density polyethylene, polypropylene, ethylene-propylene copolymer, methylpentene polymer, acid-modified polyolefin resin, or the like can be used. The thickness of the film is about 10 μm to 300 μm, preferably about 20 μm to 100 μm.

  Next, among the above heat-sealable films, in the present invention, it is particularly preferable to use an unstretched polypropylene resin film having heat-sealability. Furthermore, in the present invention, among the unstretched polypropylene resin films having the above heat-sealing properties, specifically, an ethylene-propylene copolymer is a main component, and an olefin rubber component is added thereto, and further desired. It is desirable to use an unstretched polypropylene-based resin film having heat-sealability formed by, for example, extruding and forming a composition obtained by arbitrarily adding the additive and sufficiently kneading. In the above, as the ethylene-propylene copolymer, for example, an ethylene-propylene block copolymer, an ethylene-propylene random copolymer, or the like can be used. Thus, as a copolymerization ratio of ethylene and propylene, propylene is about 80 Those containing about ˜97 mol% can be used. In the above, as the olefin rubber component, for example, one or more olefin rubber components composed of C2 to C4 such as isoprene rubber, inbutylene rubber, and ethylene-propylene rubber can be used. In the present invention, the olefinic rubber component is mainly used for improving the cold shock resistance of the product.

  In the above, the composition comprising the above-described ethylene-propylene copolymer as a main component and an olefinic rubber component added thereto is further added to other additives such as other resins such as linear low density polyethylene. In addition, a filler, a dispersant, a colorant, and the like can be arbitrarily added. Next, in the present invention, the blending ratio of the ethylene-propylene copolymer and the olefinic rubber component is 5 to 30 parts by weight, preferably 10 to 20 parts by weight of the olefinic rubber component with respect to 100 parts by weight of the ethylene-propylene copolymer. It is preferable to mix | blend in the ratio of a weight part. In the above, if it is 5 parts by weight or less, it is not preferable because the cold shock resistance is lowered, and if it is 30 parts by weight or more, the seal strength at the outer peripheral end is low, the heat resistance is low, and the internal interior during retort is low. It is undesirable because it causes fusion or the like. In the present invention, the unstretched polypropylene resin film has a thickness of about 10 μm to 100 μm, preferably about 30 μm to 70 μm.

  By the way, since the retort pouch is usually subjected to severe physical and chemical conditions, the packaging material constituting the retort pouch is required to have severe packaging suitability, deformation prevention strength, drop impact strength. Various conditions such as pinhole resistance, heat resistance, sealability, quality maintenance, workability, hygiene, etc. are required. For this reason, in the present invention, in addition to the above materials, Other materials satisfying the above conditions can be arbitrarily used. Specifically, for example, low density polyethylene, medium density polyethylene, high density polyethylene, linear low density polyethylene, polypropylene, ethylene -Propylene copolymer, ethylene-vinyl acetate copolymer, ionomer resin, ethylene-ethyl acrylate copolymer, ethylene-acrylic acid or methacrylic acid Polymers, polyolefin resins such as methylpentene polymers, polybutene resins, polyvinyl chloride resins, polyvinyl acetate resins, polyvinylidene chloride resins, vinyl chloride-vinylidene chloride copolymers, poly (meth) acrylic resins Polyacrylonitrile resin, polystyrene resin, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer, polyester resin, polyamide resin, polycarbonate resin, polyvinyl alcohol, ethylene-vinyl acetate copolymer ken A film or sheet of a known resin such as a chemical compound, a fluorine resin, a diene resin, a polyacetal resin, a polyurethane resin, or the like can be arbitrarily selected and used. In the present invention, the film or sheet may be any of unstretched, uniaxially or biaxially stretched. The thickness is arbitrary, but can be selected from a range of several μm to 300 μm. Furthermore, in the present invention, the film or sheet may be a film having any property such as extrusion film formation, inflation film formation, and coating film.

  Next, in the above-mentioned present invention, at least the heat-resistant substrate film and the heat-sealable film, or the heat-resistant substrate film, the gas barrier film are used from the outside toward the inside using the material as described above. And a method for producing a laminate in which heat-sealable films are laminated in order, as such a method, an arbitrary material is selected from the above materials in consideration of its method purpose, etc. Such a packaging material can be laminated by, for example, a wet lamination method, a dry lamination method, a solventless dry lamination method, or the like. Thus, in the present invention, when performing the above-mentioned lamination, if necessary, pretreatment such as corona treatment and ozone treatment can be applied to the film, and for example, isocyanate (urethane) And other known anchor coating agents such as polyethyleneimine, polybutadiene, and organic titanium, or polyurethane, polyacrylic, polyester, epoxy, polyvinyl acetate, cellulose, and other adhesives for lamination. An anchor coat agent, an adhesive agent, etc. can be used.

There are easy-opening means such as means that are formed at the end and can be easily torn starting from the scar group, and each of these opening means is selected or appropriately combined. It can be adopted together.

  In addition, although the notch of a 1-shape or a V-shape is used abundantly for the said notch, the shape is not restrict | limited and what kind of shape may be sufficient if it has a pointed part toward the tearing direction. The half-cut line is not limited to a continuous linear half-cut line, and may be a perforated intermittent half-cut line. Such a half-cut line may be one, but assuming a case where the tearing direction is deviated, a plurality of half-cut lines such as one on each side or two on each side of the center half-cut line, Alternatively, it can be provided in a shape that converges on the central half-cut line.

  As the opening means, various means as described above can be adopted, but it is preferable to provide an opening instruction line at least at the opening position. The opening instruction line may be displayed by anything such as a dotted line, a broken line, and a solid line, as well as characters and symbols, and can be easily provided by printing or the like.
