Description

  The present invention relates to a package containing a liquid food.

  Liquid food is generally used for people who have difficulty chewing to take nutrition. For example, Patent Document 1 contains liquid food in a packaging bag in which a spout is formed in the lower part, a tube is connected to this spout, the other end of the tube is inserted into the patient's digestive organ from the mouth and nose, A method of administering a liquid food to a patient is described. This method is, for example, a method in which a liquid food is administered to a patient who is unconscious or cannot eat from the mouth.

  On the other hand, there are cases where liquid food is ingested due to reasons such as lack of teeth. For example, in certain hospitals, nursing homes, and facilities for the disabled, etc., set meals and lunch boxes prepared by contractors are crushed and mixed as they are with a mixer and provided as liquid food. These set meals and lunch boxes are accompanied by various side meals in addition to the main meal, but without distinguishing between these main meals and various side meals, all of them are pulverized and mixed together to form one liquid meal. .

  However, in the liquid food obtained by mixing various dishes and ingredients in this way, the nutrition required for maintaining health can be ingested, but the unique taste of each dish and ingredients is lost. There is. For example, in this method, sweet foods and spicy dishes are mixed together to make a liquid food, so that neither sweetness peculiar to sweet dishes nor spiciness peculiar to spicy dishes can be tasted.

JP 2003-126217 A

  Then, an object of this invention is to provide the package body which accommodated the liquid food which can taste the flavor peculiar to each dish and foodstuff.

That is, the invention according to claim 1 is a package comprising a liquid food and a container containing the liquid food,
The liquid food packaging body is characterized in that the inside of the container is partitioned into a plurality of storage chambers, and liquid foods having different flavors are stored in the storage chambers.

  Next, the invention according to claim 2 is that the container is a tray-like container in which a plastic sheet is molded, and the partition plate that partitions into a plurality of storage chambers is integrally molded. It is a liquid food packaging body of Claim 1 characterized by these.

  Next, the invention according to claim 3 is that the plastic sheet has a multilayer structure, and an acidic group-containing layer made of a resin having a carboxyl group and a metal containing a polyvalent metal element in the layer structure. The liquid food packaging body according to claim 2, further comprising an element-containing layer, wherein the acidic group-containing layer and the metal element-containing layer are disposed at positions in contact with each other. .

  Next, the invention according to claim 4 is the liquid food package according to claim 2, wherein the height of the partition plate is not more than 5 times its width.

  According to the present invention, since the liquid foods having different flavors are stored in the respective storage rooms without being mixed with each other, it is possible to taste the flavors peculiar to the respective dishes and ingredients.

  Therefore, for example, a cooker or a person skilled in the art of valve manufactures this package and delivers it to the various facilities described above, so that these facilities can be provided to the facility occupant for each liquid food having different flavors.

It is a perspective view which shows the example of the container which concerns on this invention. It is sectional drawing which shows the example of the package body of this invention. It is sectional drawing which shows the example of the plastic sheet which comprises the container which concerns on this invention. It is principal part sectional drawing which shows the relationship between the height and width of the partition plate of the container which concerns on this invention.

  The package of the present invention includes a plurality of liquid foods and a container containing the liquid food as essential components. In addition, it is desirable to provide a lid member that seals the container opening.

  The container needs to be partitioned into a plurality of storage chambers. FIG. 1 is a perspective view showing an example of such a container 11.

  The container 11 shown in this example is a tray-like container formed by molding a plastic sheet, and partition plates 11a and 11b partitioning into a plurality of storage chambers are integrally formed. In this example, it is divided into three accommodation chambers by the partition plates 11a and 11b.

  FIG. 2 is a cross-sectional view of the package 1 in which the liquid foods 12 a and 12 b are accommodated in the container 11 and sealed with the lid member 13. The liquid food 12a and the liquid food 12b have different flavors. For example, the liquid food 12a is sweet and the liquid food 12b is spicy. And these are accommodated in each accommodating chamber, without mutually mixing with the partition plate 11a.

  If it explains more concretely, for example, when Chikuzenni is a side dish, it is necessary to grind with a mixer each ingredient which constitutes this Chikuzenni to make a liquid food, and to store each in a separate storage room. That is, the carrot simmered food that constitutes Chikuzenni is pulverized with a mixer to obtain a liquid food 12a. On the other hand, the sweet simmered food is pulverized with a mixer to obtain a liquid food 12b. This is because the carrot simmered food and the simmered simmered food are different in flavor, that is, taste. And by accommodating these in separate accommodation chambers, both can be accommodated separately, without compromising both the flavor of the carrot simmered and the flavor of the simmered simmered potato. . The same applies to chicken thighs and shiitake mushrooms.

  On the other hand, when Mabo tofu is a side dish, it is not necessary to separately make the meat and tofu constituting this Mabo tofu into a liquid food. What is necessary is just to pulverize and mix these marvo tofu containing meat and tofu with a mixer into a liquid food. In this case, the taste (flavor) peculiar to Mabo tofu is not impaired even if Mabo tofu is integrated into a liquid food.

If there are both Chikuzenni and Mabo tofu as side dishes, of course, carrot stew
It is necessary to store the boiled sugarfish and marvo tofu as separate liquid foods in separate storage rooms.

  Next, the container 11 can be manufactured by a sheet forming method such as a vacuum forming method, a pressure forming method, and a plug forming method using a plastic sheet as a raw material. The plastic sheet constituting the container 11 may be made of any material, but the plastic sheet has a multilayer structure, and the layer structure includes an acidic group-containing layer made of a resin having a carboxyl group, a polyvalent metal element In addition, it is desirable that the acidic group-containing layer and the metal element-containing layer are disposed at positions where they are in contact with each other. When the acidic group-containing layer and the metal element-containing layer are arranged at positions where they are in contact with each other, the carboxyl group of the acidic group-containing layer and the polyvalent metal element of the metal element-containing layer are ion-bonded to each other to form an oxygen barrier property. This is because the liquid food is prevented from being oxidized. In addition, the container 11 arranged in a position where the acidic group-containing layer and the metal element-containing layer are in contact with each other in this way accommodates the liquid food 12 in the accommodation chamber and seals it with the lid member 13, and then the retort. Can be sterilized. Even after retort sterilization, the oxygen barrier property of the container is maintained without being impaired. For example, even when a cooker cooks, stores, and retort sterilizes, the liquid food 12 is sanitary even when delivered to the various facilities described above. Can be kept in.

  For example, as shown in the cross-sectional view of FIG. 3A, a metal element-containing layer 112 and an acidic group-containing layer 113 are sequentially laminated on one side of the base sheet 111, and the polyolefin resin layers 114, 115 is a five-layer plastic sheet with 115 disposed thereon. In addition, the order of the metal element-containing layer 112 and the acid group-containing layer 113 is changed, and the acid group-containing layer 113 and the metal element-containing layer 112 are sequentially laminated on one side of the base sheet 111, and both the front and back sides thereof are laminated. A plastic sheet having a five-layer structure in which the polyolefin resin layers 114 and 115 are arranged can also be used (see FIG. 3B).

  The acidic group-containing layer 113 can be formed by blending an additive into a carboxyl group-containing resin and applying it by dissolving or dispersing in a solvent. A plasticizer can be illustrated as an additive. By blending the plasticizer in the acidic group-containing layer 113, the stretch moldability of the acidic group-containing layer 113 can be improved. Further, it is possible to neutralize a part of the carboxyl groups of the carboxyl group-containing resin by adding a monovalent metal element or ammonia.

  Next, the carboxyl group-containing resin constituting the acidic group-containing layer 113 includes a homopolymer of a monomer having a carboxyl group, a copolymer obtained by copolymerizing two or more of these carboxyl group-containing monomers, or these carboxyl groups. Copolymers of containing monomers and other monomers can be used.

  Examples of the carboxyl group-containing monomer include α, β-ethylenically unsaturated carboxylic acids and polysaccharides. Examples of the α, β-ethylenically unsaturated carboxylic acid include acrylic acid, methacrylic acid, itaconic acid, maleic acid, fumaric acid, and crotonic acid. Examples of polysaccharides include alginic acid, carboxymethyl cellulose, and pectin.

  On the other hand, examples of other monomers copolymerized therewith include olefins such as ethylene and propylene. Further, a carboxylic acid vinyl ester such as vinyl acetate may be used. Alternatively, alkyl acrylates, alkyl methacrylates, alkyl itaconates, vinyl chloride, vinylidene chloride, vinyl fluoride, vinylidene fluoride, styrene, and the like may be used. In addition, when carboxyl group-containing resin consists of a copolymer of a carboxyl group-containing monomer and another monomer, it is desirable that the carboxyl group-containing monomer occupies 60 mol% or more.

  Next, as a plasticizer blended in the carboxyl group-containing resin, glycols can be exemplified as a representative example. For example, ethylene glycol, trimethylene glycol, propylene glycol, tetramethylene glycol, 1,3-butanediol, 2,3-butanediol, pentamethylene glycol, hexamethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, polyethylene oxide, etc. It is. In addition, sorbitol, mannitol, dulcitol, erythriol, glycerin, lactic acid, fatty acid, and the like can be used.

  The blending ratio of the carboxyl group-containing resin and the plasticizer is desirably in a mass ratio such that the carboxyl group-containing resin / plasticizer is 70/30 to 99.1 / 0.1.

  Next, the metal element-containing layer 112 can be formed by applying a polyvalent metal element alone or a polyvalent metal element compound and a resin binder dissolved or dispersed in a solvent.

  As a polyvalent metal element, an alkaline earth metal element, a transition metal element, or the like can be used in addition to a typical metal element such as an aluminum element. Examples of alkaline earth metal elements include beryllium, magnesium, and calcium. Examples of the transition metal element include titanium, zirconium, chromium, manganese, iron, cobalt, nickel, copper, and zinc. Examples of these compounds include oxides, hydroxides, carbonates, organic acid salts, inorganic acid salts, ammonium complexes, complexes of secondary to quaternary amines, and carbonates and organic acid salts of these complexes. Specific examples of organic acid salts include acetate, oxalate, citrate, lactate, phosphate, phosphite, hypophosphite, stearate, monoethylenically unsaturated carboxylic acid A salt etc. can be mentioned. Examples of inorganic acid salts include chlorides, sulfates, nitrates, and the like.

  As the resin binder constituting the metal element-containing layer 112, any thermoplastic resin can be used. Further, if the metal element-containing layer 112 is sufficiently thin, even a thermosetting resin can be used as a resin binder. For example, alkyd resin, amino alkyd resin, melamine resin, acrylic resin, nitrified cotton, urethane resin, polyester resin, phenol resin, amino resin, fluorine resin, silicone resin, epoxy resin, vinyl resin, cellulose resin, natural resin, etc. .

  The compounding ratio of the metal element simple substance or metal element compound and the resin binder is desirably in a range in which the metal element simple substance or metal element compound / resin binder is 1/100 to 10/1.

  In addition, as the base material sheet 111, arbitrary thermoplastic sheets can be used. For example, a polyethylene sheet, a polypropylene sheet, a polyester sheet, a polyamide sheet, and the like. The polyolefin resin layers 114 and 115 are not essential components, but are desirably provided on the inner surfaces in contact with the liquid foods 12a and 12b in order to maintain hygiene. As the polyolefin resin layers 114 and 115, polyethylene, polypropylene, or the like can be used. The polyolefin resin layers 114 and 115 can be formed by adhering a previously formed polyolefin film with an adhesive. Alternatively, the polyolefin resin layers 114 and 115 may be formed by a melt extrusion coating method.

Thus, when the container 11 is comprised with the plastic sheet of the multilayer structure which laminated | stacked the metal element containing layer 112 and the acidic group containing layer 113 on the single side | surface of the base material sheet 111, this was sheet-formed into the tray-shaped container with a partition. Sometimes, separation between the layers may occur at the tops of the partition plates 11a and 11b having a large curvature. Therefore, as shown in FIG. 4, when the height of the partition plates 11a and 11b is T and the width is D, the height T of the partition plates 11a and 11b is formed to be not more than 5 times the width D. It is desirable to do. By making the height T of the partition plate not more than 5 times the width D, it is possible to prevent peeling between the layers.

  Next, as the lid member 13, it is desirable to use a sheet that can be heat-sealed to the flange of the container 11 and has excellent oxygen barrier properties. As this sheet, a sheet having a multilayer structure in which the metal element-containing layer 112 and the acid group-containing layer 113 are laminated can be used as in the case of the plastic sheet constituting the container 111. A multilayered sheet having a vapor deposition layer as an oxygen barrier layer can also be used. For example, a multilayer film in which an oxygen barrier vapor-deposited layer is formed on one side of a polyester film and a heat seal layer is provided on the vapor-deposited layer. Examples of the oxygen barrier deposition layer include a deposition layer of a metal such as aluminum and an inorganic deposition layer such as silicon oxide and aluminum oxide. Moreover, since the heat seal layer is in contact with the liquid foods 12a and 12b, it is desirable that the heat seal layer is made of a highly hygienic polyolefin resin.
