  The present invention relates to a food cup used for serving cooked foods such as lunch boxes, etc., and has good shape retention and excellent food holding power, so that there is no collapse of food arrangement due to carrying, water absorption and oil absorption The present invention relates to a food cup that is excellent in properties, maintains the flavor of food, and does not transfer to other dishes.

2. Description of the Related Art Conventionally, food cups made of aluminum foil, film, film and paper laminated, and oil-repellent paper have been used for the purpose of serving cooked food such as lunch boxes and preventing taste transfer. Recently, lunch boxes sold at convenience stores and the like are heated in a microwave oven, so film food cups have become widespread. However, those using aluminum foil and a single film have a problem that they do not have water absorbency and oil absorbency, and the food remains sticky and the texture is lowered. In order to solve this problem and to impart water absorbency and oil absorbency, some aluminum and film are laid with paper, but this is insufficient to maintain the taste of food.
In addition, the food holding power is small and the gathers are easy to spread, so there is a problem that the food cannot be held or the food spills when moving the lunch box etc. there were.

  Patent Document 1 discloses a container in which a nonwoven fabric mainly composed of polyester fibers is bonded to one side of an unstretched polyester film, and the nonwoven fabric is molded so as to be inside the container. Since this container is integrally molded, the nonwoven fabric is compressed by pressure bonding, so there is a problem that water absorption and oil absorption are insufficient. Further, since the film is stretched integrally, the design property cannot be imparted by the method of printing on the film.

Patent Document 2 discloses a side surface formed by a laminate in which a thermoplastic synthetic long-fiber nonwoven fabric having a basis weight and a thickness of 10 to 50 g / m ² and 15 to 300 μm is bonded to a thermoplastic film having a thickness of 15 to 100 μm, respectively. A food cup having a pleat is disclosed. Although this food cup has improved water absorption and oil absorption, when heating food with much water vapor and oil generation when heated in a microwave oven, the water absorption and oil absorption are still insufficient. The texture may not be kept good and is not always satisfactory.

The cup for food of the present invention is excellent in water absorption and oil absorption, maintains good food taste, has good shape retention, prevents food from spilling due to spread of food cup gathers, and can be applied to other foods. In addition to preventing the transfer of taste, even when foods that generate a lot of water vapor or oil when heated are heated in a microwave oven, etc., the water absorption and oil absorption are sufficient, and the oil return is low and the texture is good A food cup suitable for bento or frozen food for lunch that can be kept.

The food cup of the present invention is a food cup formed of a laminate of a dry nonwoven fabric and a thermoplastic film, having a gather on the side surface, and bonded so that the nonwoven fabric surface is inside the cup. The shape of the cup opening is not limited, such as a circle, an ellipse, a square, and a rectangle. In the gathering process, the height of the gather is not particularly limited, but generally, the height between the gathers and the valleys in the opening is preferably in the range of 3 mm to 8 mm. Further, the distance between the ridges, that is, the pleat distance is not particularly limited, but a range of 5 mm to 15 mm is preferable. The dry nonwoven fabric is a dry nonwoven fabric formed by using cellulose fibers as raw fibers and applying a binder to a web formed from raw fibers defibrated in the air and drying them to bond the raw fibers together.

The dry nonwoven fabric used in the present invention is a dry nonwoven fabric formed by using cellulose fibers as raw fibers, adding a binder to the web formed from the raw fibers defibrated in the air, and bonding the raw fibers to each other by drying. is there

[Cellulose fiber]
Cellulose is hydrophilic and has excellent absorbency to moisture and oil, but is insoluble in cold / hot water, oil and organic solvents, and has high heat resistance. Cellulose fibers are used as raw fibers for the dry nonwoven fabric. Such cellulose fibers are derived from natural plants such as rayon, polynosic, cupra, lyocell, acetate and other non-wood pulp such as cotton, hemp, wood pulp, straw, bagasse, straw, kenaf, mulberry Can be mentioned. Wood pulp is preferably used because it is produced industrially and is easy to obtain inexpensive and stable quality. Wood pulp is classified into conifer pulp and hardwood pulp depending on the wood used as a raw material, and is classified into mechanical pulp and chemical pulp by the method of pulping wood. Mechanical pulp includes pulverized wood pulp that breaks wood into fine fibers by mechanical force, thermomechanical pulp by heat and mechanical force, and chemical pulp includes kraft pulp, sulfide pulp, alkaline pulp, etc. . These raw fibers are defibrated in air and used for dry nonwoven fabrics. Since pulping is usually performed in a wet process, the treated pulp fiber is in a state of being dispersed in water, but for use in a dry nonwoven fabric, in the present invention, the dried pulp fiber is provided in the form of a deep-fried pulp or the like. Is used.

The cellulose fibers used for the dry nonwoven fabric are short fibers and chopped fibers having an average fiber length of 1 mm to 20 mm, and preferably 2 mm to 10 mm. If the average fiber length is less than 1 mm, the amount of adhesive necessary to bond the fibers increases, the texture of the formed nonwoven fabric decreases, or the strength of the nonwoven fabric is insufficient due to insufficient adhesion. On the other hand, when the average fiber length exceeds 20 mm, the formation of the dry nonwoven fabric deteriorates and becomes a non-uniform sheet, which is not preferable. The preferred range of the fiber diameter of these cellulose fibers is about 5 μm or more and 50 μm or less. In the case of natural cellulose fibers such as pulp fibers, the fiber diameter varies depending on the plant from which they are derived. Among wood pulp, softwood kraft pulp having a fiber length and a fiber diameter in a preferable range is particularly preferably used.
In the dry nonwoven fabric of the present invention, synthetic fibers formed by combining at least one thermoplastic resin such as polyethylene resin, polypropylene resin, and polyester resin and inorganic pigments are used in combination as long as the object of the present invention is not impaired. You can also.

〔binder〕
Raw material fibers made of cellulose fibers are defibrated in the air, and a web is formed from the defibrated raw material fibers. By applying a binder to the web and drying it, the raw fibers in the web are bonded together to form a sheet. As the binder, aqueous solutions or aqueous dispersions (emulsions or suspensions) of various polymer substances that are dried and insoluble in water are used. From the viewpoint of water resistance after drying, a binder composed of an aqueous dispersion of a polymer substance is preferable. For example, an acrylic polymer, a styrene / butadiene copolymer, a vinyl chloride / vinyl acetate copolymer, a polyvinyl acetate resin, A binder made of an aqueous dispersion of various polymer materials such as ethylene / vinyl acetate copolymer can be used. For use in contact with foods, a self-emulsifying type polymer material dispersion containing no surfactant such as an emulsifier is preferable, and a self-emulsifying type ethylene / vinyl acetate copolymer excellent in adhesiveness to cellulose fibers is used. The emulsified liquid can be particularly preferably used as the binder of the present invention.

(Dry nonwoven fabric)
In the present invention, water vapor generated when food is heated by adopting a dry nonwoven fabric with a large amount of voids, which is produced from a web formed by defibrating raw material fibers in air and defibrated raw material fibers It is possible to effectively prevent oil return that can absorb the oil and the oil, and the oil that cannot be absorbed again adheres to the food and impairs the flavor and texture of the food. However, in the case of such a dry nonwoven fabric, since raw fiber having a short fiber length such as an average fiber length of 1 mm or more and 20 mm or less is used, the problem is that fibers adhere to food and fiber waste tends to remain in food. was there. In the present invention, a web is formed from raw fibers obtained by defibering the above-described cellulose fibers in the air, a binder is applied to the web, and drying is performed to bond the raw fibers in the web to each other. Use dry non-woven fabric. A dry non-woven fabric that has been bonded with a binder and dried and bonded to the web has contact points between the fibers bonded with the binder, so even if it is made up of short fibers, the fibers can be prevented from falling off. The problem that scraps remain in food can be effectively prevented. The amount of the binder used in the dry nonwoven fabric of the present invention depends on the type of fiber used and the fiber length, but is preferably in the range of 5 to 30% by weight with respect to the total weight of the nonwoven fabric.

The dry nonwoven fabric used in the present invention is a dry nonwoven fabric produced by using cellulose fibers having a short fiber length as raw material fibers, which has a large amount of voids and prevents the fibers from falling off. It is an excellent dry non-woven fabric that can sufficiently absorb oil and can effectively prevent oil return and that there is no problem that fiber waste remains in food.

The dry nonwoven fabric used in the present invention preferably has a basis weight of 30 g / m ² or more and 120 g / m ² or less, more preferably 35 g / m ² or more and 80 g / m ² or less, and still more preferably. 40 g / ^{m 2} or more, is used as a 60 g / ^{m 2} or less. If it is less than 30 g / m ^2, the absorption and water vapor and oil generated from food, because it is insufficient to prevent the oil return, easily impair the food taste and texture, it exceeds 120 g / m ² sheet itself Is too thick, making cup molding difficult, which is not preferable.

The thickness of the dry nonwoven fabric is preferably in the range of 500 μm to 2000 μm, more preferably in the range of 1000 μm to 1700 μm. If the thickness is less than 500 μm, there are insufficient gaps that can contribute to the absorption of water vapor and oil generated from food, so that the absorption of water vapor and oil tends to be insufficient, and the flavor and texture of the food tend to be impaired. This is not preferable because it becomes too thick and cup molding becomes difficult.

[Film]
Examples of the thermoplastic film used in the present invention include polyolefin resins such as low-density polyethylene, high-density polyethylene, polypropylene, copolymerized polyethylene and copolymerized polypropylene, aliphatic polyester resins, aromatic polyester resins, polylactic acid and copolymer. Polyester resins such as polymerized polyester, polyamide resins such as nylon 6, nylon 66 and copolymer nylon, ethylene / vinyl acetate copolymer resins, polyurethane resins, polyolefin elastomers, polyester elastomers, and polyamide elastomers A laminated film of two or more layers is used.

The thickness of the film is 15 to 100 μm, preferably 20 to 70 μm, more preferably 25 to 50 μm. If the thickness is less than 15 μm, it may not be possible to form the shape neatly, or the shape may not be sufficiently maintained, and food may spill and transfer to other foods. On the other hand, when the thickness exceeds 100 μm, the shape can be maintained, but the bonding process with the nonwoven fabric and the heat formability are lowered, and the productivity tends to be lowered.

[Manufacture of food cups]
The food cup of the present invention is shaped by being superposed and bonded so that the dry nonwoven fabric is inside the cup. Adhesion between the dry nonwoven fabric and the film can be carried out in a conventional manner using a solventless adhesive or the like, for example, by superposing the dry nonwoven fabric and the film and subjecting them to a hot press process. Moreover, the food-type cup of this invention can be obtained by shape | molding the dry-type nonwoven fabric and film cut | disconnected in the appropriate magnitude | size to the predetermined | prescribed shape of the cup which has a gather on the side surface by a hot press process. In this case, the film and non-woven fabric can be bonded in advance, then cut to an appropriate size, and shaped into a predetermined shape in the hot press process. This is preferable because it is possible.

In the hot press process, a plurality of sheets may be formed as necessary, and the productivity increases as the number of sheets stacked increases. The general conditions for forming by hot pressing can be used. For example, at least one of a male die or a female die of a hot press machine may be heated to about 100 ° C. to 200 ° C. according to the material to be used and hot pressed for about 1 to 10 seconds.

The surface of the dry nonwoven fabric inside the food cup of the present invention sufficiently absorbs water vapor and oil generated during heating of the food, and the oil that cannot be absorbed again adheres to the food and impairs the flavor and texture of the food. This effectively prevents a so-called oil return phenomenon.

The water absorption per unit area of the dry nonwoven fabric inside the food cup of the present invention is preferably in the range of 200 g / m ³ or more and 2000 g / m ³ or less, more preferably in the range of 500 g / m ³ or more and 2000 g / m ³ or less. It is. The oil absorption of the food cup of the present invention is preferably in the range of 200 g / m ³ or more and 2000 g / m ³ or less, more preferably in the range of 600 g / m ³ or more and 2000 g / m ³ or less. When the water absorption rate and the oil absorption rate are within this range, it is preferable as a food cup for sufficient water absorption and oil absorption performance.

In addition, the oil used in the oil absorption test and oil return test in the present invention may be any oil as long as it is used as an edible vegetable oil in JAS. However, it is easy to obtain and widely used salad oil (Nisshin Oilio Co., Ltd. )) Was dropped on the nonwoven fabric surface and absorbed for 1 minute, and then a filter paper (GRADE No. 2 (manufactured by ADVANTEC)) was piled up and left under a load of 1.17 g / cm ² for 1 minute, When heating the food as a food cup, if the oil return is 50% or less when the weight ratio of the oil transferred from the nonwoven fabric surface to the filter paper to the original oil amount (0.5 g) is 50%, It is preferable because the oil that cannot be absorbed can be effectively prevented from adhering to the food again to impair the texture.
