[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A food tray will be described.
The tray may be made of any material that is resistant to cold, heat, and oil. An example is a thin polypropylene tray. FIG.
As shown in the figure, a tray having two or more storage chambers (3) for separating and storing food having a peripheral portion (2) in an upper opening (1), and each of the storage rooms is joined at the peripheral portion. It is.
Preferably, the peripheral portion between the storage chambers is joined so that it can be cut off. For example, the peripheral portion between the accommodation rooms (3, 3) is connected at only two points (4, 4). There are at least two portions connected at two points (4, 4), and the other portions are long continuous cuts, which can be easily cut off. FIG. 1 illustrates a case where two points are connected, but it is sufficient that at least one point is connected. When the peripheral portion (2, 2) is grasped with a finger and pulled, the portion connected at the two points (4, 4) can be easily separated and divided. If they are joined at perforations as in the past, they cannot be subdivided unless all parts connected at many points are separated, but in the case of the present invention, the parts other than those connected at points are long and continuous. Since the cut is made and the part is separated from the beginning, it can be easily separated as described above. FIG. 2 shows a state in which the food tray shown in FIG. 1 is subdivided. Two points (4
The portion connected in 4) is cut off to form a subdivision tray having one storage chamber (3). FIG. 2 shows one storage chamber (3) cut out.

[0008] It is most preferable that the portion connected by the two points (4, 4) is located near a corner which is to be separated. In this case, simply pinch and pull the portion of the peripheral edge (2) near the corner where it was separated,
It can be easily separated from the edge. In subdividing a large tray before subdivision, the most easy-to-grip location is the part of the peripheral edge (2) that is as close as possible to the corner when separated, so it is connected in the vicinity, that is, around the corner when separated. It is most preferable to do so.

Each accommodating room (3) has a bellows-like uneven wall surface (5).
It is composed of The bellows-like uneven wall surface (5) is a pair of opposing side surfaces in FIG. 1, but is not limited to this mode. be able to. The size of the bellows-like unevenness can be determined according to the type of food to be stored, the size of the storage room, and the like, so that water vapor and oil can escape more efficiently.

The food tray is placed in a packaging bag as it is or with its top covered with a wrap film. Packaging may be performed in any of the usual forms.

The food to be stored in the tray of the present invention is a cooked food for microwave cooking, particularly a frozen frozen food for microwave cooking, and preferably has a shape. Pre-cooked frozen foods for cooking in a microwave oven have a contact surface with a container such as a dish, in which the foreskin is swollen by steam and oil generated from the product when the microwave is heated, and the quality of the foreskin deteriorates from its original quality. It is a frozen product of encased or foreskin food such as firewood, shrimps, meatballs, etc., and most preferably a frozen food having been subjected to frying.

[0012] When the excess oil is successfully dropped off, the frozen food having undergone the frying treatment can be reproduced by heating in a microwave oven, although the quality is close to that of deep fry. When using the tray of the present invention, when heating the microwave oven, based on the bellows-like uneven structure of the wall of each accommodation room, to contact the food only at the apex of the convex portion, to form a space between the concave portion and the food surface The extra oil drops off, preventing the stickiness at the bottom of the food and preventing the quality from being deep fried.

When the frozen food that has been subjected to the frying treatment is a delicate food, such as a wrapped wheat flour, which is crisp and finished with the frying, when heated in a microwave oven, it comes into contact with water vapor generated from the wrapped wheat and oil that falls off. To prevent surface wetting and stickiness effectively.

The food package for a microwave oven packaged using these food trays of the present invention can be prepared by cutting the entirety of the food compartments together or by cutting out a required number of the accommodation chambers, and cooking the foods stored in the microwave oven. We can eat deliciously. The remaining portion can be stored in the refrigerator and cooked and eaten in the same manner at a later date.

[0015]

The tray of the present invention can prevent impact from the side and protect crisp and delicate delicate foods stored therein, based on the bellows structure of each storage chamber. Cooked frozen foods for cooking in a microwave oven are wrapped with steam or oil generated from the product when the microwave oven heats the contact surface with a container such as a dish in the case of encased or wrapped food such as harumaki, shumai, and meatballs. However, if the tray of the present invention is used, the food comes into contact with the food only at the top of the convex portion due to the bellows-like uneven structure of the wall of each storage room when the microwave oven is heated. In addition, since a space is formed between the concave portion and the food surface, water vapor escapes from the folds of the bellows-like unevenness, thereby preventing the food surface from being wet. For oiled products, excess oil drops off, preventing stickiness at the bottom of the food and recreating products that are close to the quality of deep fried foods.

Tray having a bottom surface with irregularities or holes is known before the present application. However, in order to reduce the amount of packaging material used and to make the packaging itself not bulky, especially when subdividing, However, it is required that the packaging fits the contents.In this case, the unevenness on the bottom surface was not enough, but the folds of the bellows-like unevenness were It also worked effectively against the drop off of excess oil. The trays of the present invention can be separated and cooked one by one on the basis of the perimeter that can be cut off between the accommodation chambers, so that only the necessary amount can be used. When storing the remaining portion in the refrigerator, no space is required and the space in the refrigerator can be used effectively.
