Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a food packaging container having oil absorption and water absorption, and more particularly to a food packaging container used to bring back fried food products.

[0002]

[Prior Art]

 Traditionally, fried foods have been packed in bags made of oil-resistant paper or plastic film, but fried foods have to be cleaned by removing excess oil and then re-oiled. May attach to foods and may contain extra oil, which may impair the taste.Furthermore, since the foods immediately after being fried are brought back while they are hot, they are made of plastic and have a rough surface. The tray is attached to a container made by molding paperboard, and the oil that falls is collected in the recess of the tray.

[0003]

[Problems to be solved by the device]

 As mentioned above, as a packaging container for bringing hot foods fried in oil back, we have put a tray made of plastics into a container made of paperboard, but at the store it is made of paperboard. It is troublesome to assemble the boxed containers and to incorporate a plastic tray, and it requires a lot of storage space for packaging materials.

Further, the bottom of the tray of plastics is provided with irregularities so that the oil may be accumulated. However, the oil may contact with the foods during transportation and adhere to the foods again, thereby deteriorating the taste. There is. Furthermore, foods immediately after being fried in oil may also emit water vapor, and water droplets may adhere to the back surface of the lid or the tray of plastics, and when the water droplets reattach to the foods, the portion becomes soft and the taste is deteriorated. I was afraid.

An object of the present invention is to provide a food packaging container in which oil or water does not redeposit on food and does not require materials other than a container such as a plastic stray.

[0006]

[Means for Solving the Problems]

 As a result of studies aimed at solving such problems, the present invention has developed a corrugated corrugated sheet of paper having oil absorption and water absorption and a single-sided corrugated sheet with a liner made of paperboard attached. This can be solved by using a packaging container made by box-making so that the rolled paper is on the inside.

It is to be noted that a laminated paper of wet strong paper and oil resistant paper having oil absorption and water absorption, or a laminated paper provided with an oilproof layer between the wet strong paper and plain paper is used as the liner paper, or a liner is used. It is advisable to use a grease-proof paperboard for −, and to interpose a fine superabsorbent resin between the wet strong paper and the grease-proof paper or the oil-proof layer.

[0008]

[Action]

 In the packaging container according to the present invention, the corrugated paper is located on the inner wall surface, and foods are carried on the top of the corrugated paper. Excess oil of foods is absorbed at the contact surface with the corrugated paper, or flows down to the valley of the corrugated paper and is absorbed by the corrugated paper. Water vapor evaporated from foods is condensed and absorbed on the surface or inside of the corrugated paper.

The greaseproof paper, the oilproof layer, or the greaseproof paperboard blocks oil and water absorbed by the wet strong paper of the corrugated paper and prevents the oil from penetrating and diffusing into the liner. The super absorbent resin absorbs the water absorbed by the wet strong paper.

【Example】

 The present invention will be described with reference to the embodiments shown in the drawings. The present invention, as shown in FIG. 1, is a food packaging container which is made by using a single-sided corrugated ball (1) so that the corrugated paper is placed inside.

This single-sided ball (1) is formed by a liner (2) and a liner (3). In the single-sided ball (1) shown in FIG. Is a wet-strength paper (5) made from wood pulp as the main component and mixed with a wet-strength resin, etc., and paper made from highly viscous beaten wood pulp, or oils and fats. It is made of paper laminated with greaseproof paper (6) treated to have resistance.

That is, the wet strong paper (5) used here is a bleached wood pulp such as a towel paper base paper having a basis weight of about 45 g / m ² , and is wet with melamine resin, urea formaldehyde resin, etc. It is recommended to use wet strong paper that is made by blending a strong resin into paper without any size.For the grease-resistant paper (6), paper made by viscous beating of wood pulp is soaked with water and passed through a super-kinder. It is advisable to use a greasy paper having a basis weight of about 25 to 50 g / m ^{2 which} has been clarified, or a greaseproof paper made by adding paper such as a fluororesin.

[0013] Instead of the grease-proof paper (6), plain paper used for packaging such as kraft paper is used, and a hot-melt resin such as polyethylene or polypropylene or an emulsion type adhesive is used to wet the strong paper (5). The oil-proof layer (7) may be formed on the pasting surface by pasting. In addition, between the wet strong paper (5) and the greaseproof paper (6), between the wet strong paper (5) and the oilproof layer (7) formed between the plain paper, a fine powder of a super absorbent resin, for example, It is advisable to interpose a vinyl acrylate copolymer. In this case, the paperboard used for the liner (3) is not particularly limited, but it is preferable to use ivory-coated white paperboard having a basis weight of 150 to 300 g / m ² .

In the single-sided corrugated ball (1 ′) shown in FIG. 3, the corrugated paper (2) is made of wood pulp as a main component, and is composed of paper without any size. Use paper liner (3) made from highly viscous beaten wood pulp, or paperboard laminated with greaseproof paper (6) treated to resist oils and fats. It was what I had.

That is, it is desirable that the wet strong paper used for the corrugated paper (2) is thick and has a grammage of 70 to 150 g / m ² and has rigidity, and the liner (3) is a glass sheet. -It is recommended to use a paper made by adding paper or fluororesin to the paper and pasting it on an ivory or coat paperboard.In this case, the paper (6) of the liner (3) should be used. ) Side is attached with the stepping paper (2).

Further, the liner (3) may be a greaseproof paperboard internally or impregnated with a chemical that imparts oil resistance and water resistance, for example, a fluorine-based resin or the like. It is no problem to use paperboard that has an oil-proof layer formed by laminating polyethylene, polypropylene, etc. on the surface to be bonded with.

When the wet strong paper having oil absorption and water absorption is used as the staged paper (2), the adhesive (4) used when it is bonded to the liner (3) is insoluble in water after drying. It is advisable to use a synthetic resin-based adhesive or the like.

[0018]

[Effect of the device]

 Since the present invention is configured as described above, it is easy to assemble and does not require a plastic tray or moisture absorbing paper, so that it can be provided at a low cost and the stock area is reduced.

When using a fried food such as fried chicken in a container for use, excess oil is not absorbed in the corrugated paper and does not collect in the valley of the corrugated paper. The water vapor generated without being adhered is absorbed without condensing on the surface of the corrugated paper to form water droplets, so that there is no possibility of re-adhesion to the food, and therefore the taste is not spoiled.

Further, since oil and water absorbed by the wet strong paper of the staged paper are blocked by the greaseproof paper, the oilproof layer and the greaseproof paperboard, there is no possibility of permeating to the surface of the container. is there.

[0021] Further, since the food is carried on the stage of a liner and there is a gap between the liner and the liner forming the surface of the container, heat is not transferred and the container surface does not become hot, and It has the advantage that the food is difficult to cool.
