Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a food container for microwave ovens that can be heated to roast or stir-fry the food when heating the food in a microwave oven. It is.

(Prior Art) Conventionally, a microwave oven has been used as a cooking device to heat frozen cooked foods or cold cooked foods for consumption. As microwave ovens have become more widespread, a variety of new processed foods have been created that are suitable for use with microwave ovens. For example, microwave popcorn, which has recently become popular,
The popcorn is popped inside the package, and when this microwaveable popcorn is irradiated with microwaves, the pressure of the steam generated ruptures the inner container, making it easier to remove the contents of the outer carton. It is designed to open like this.

(Problem to be solved by the invention) Containers for frozen cooked foods or other cooked foods that are heated in a microwave oven and made edible are generally used only to contain and hold the cooked food; When heated, the moisture in the cooked food heats it to a state where it is steamed, and heat treatments such as roasting or stir-frying are not possible.
Even in popcorn for microwave ovens that can be seen these days, a mechanism is devised to open the popcorn to make it easier to take out the food inside, but no consideration has been given to heating the popcorn to roast or stir-fry it.

(Means for solving the problem) The present invention installs a heat-resistant porous plate that adsorbs edible oil on the inner bottom of the container, and attaches a heat insulating layer to the outside of the bottom of the container. This device allows food placed on a heat-resistant porous plate adsorbed with edible oil to be heat-treated to a state of roasting or stir-frying simply by heating it in a microwave oven. When this microwave food container is heated in the microwave,
The temperature reaches a temperature of 100°C or more, which is higher than the food above it, and the food is heated by this high temperature. In addition, since the cooking oil is adsorbed and retained on the porous plate, it is extremely unlikely to transfer to the food, and as with cooking with cooking oil applied to a frying pan, the food can be heated to high temperatures with almost no oil on the food. heated to. If the edible oil is adsorbed and held on the porous plate, the high temperature will continue, but it will be protected from heat by the heat insulating layer attached to the outside of the bottom of the container, and the high temperature will be reliably maintained without heat escaping. At this time, if the porous plate is impregnated with a large amount of edible oil, the amount of edible oil that will adhere to or transfer to the food will increase.
Food is heated to high temperatures during frying. In conventional microwave food containers, the food content is
The temperature will not exceed 100℃.

(Example) The microwave food container of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a container, which can be appropriately formed into a circular shape, a polygonal shape, or the like. Further, the material of the container 1 may be any material that is generally used in microwave ovens, but it is preferably made of silicon-treated paper, thick paper laminated with various resins, or a heat-resistant resin thin plate. be.

A heat-resistant porous plate 2 adsorbing edible oil is installed at the inner bottom of the container 1. Heat-resistant porous plate 2
The material is not particularly limited, and may be any material as long as it is harmless and can adsorb and retain edible oil. For example, paper, drawing paper, cardboard, nonwoven fabric, diatomaceous earth, etc. are used in the form of a plate. Edible oil is generally used for human consumption, and is not limited to liquid oil; butter and other solid fats can also be used.

A heat insulating layer 3 is provided outside the bottom of the container 1 . The heat insulating material layer 3 may be any material that has heat insulating properties, and like the heat-resistant porous plate 2,
It may be formed to an appropriate thickness using paper, drawing paper, cardboard, nonwoven fabric, diatomaceous earth plate, or the like. In the drawing, the heat insulating layer 3 is provided so as to be held on the outside of the bottom of the container 1 by the cover 4, but if the structure is such that the insulating layer 3 is held, it can be formed in any way. Good too.

The food 5 is placed on a heat-resistant porous plate 2 that has adsorbed cooking oil.
The food can be roasted or stir-fried by adjusting the amount of cooking oil adsorbed on the food. Therefore, the food 5 placed on the heat-resistant porous plate 2 is suitable for roasting. It is preferable to select foods that have been cooked or are suitable for frying.
Reference numeral 6 denotes a coating film for the opening of the container 1, which is hygienic as it prevents the entry of insects and the like, and it is preferable to use a transparent film such as cellophane paper so that the contents can be seen through. The coating film 6 is selected according to the shape of the container 1,
In some cases, this is not always necessary.

When the microwave food container of the present invention is used for consumption, when it is heated in a microwave oven, the cooking oil adsorbed on the porous plate becomes heated to a high temperature of 100℃ or more, and the food becomes porous without being transferred to the food. The porous plate is held at a high temperature because the heat does not escape due to the heat insulating layer attached to the outside of the bottom of the container. Therefore,
The food placed on it is heat-treated in a roasting or stir-frying state.

(Effects of the invention) According to the invention, cooking oil adsorbed on a heat-resistant porous plate reaches a temperature higher than the food when heated in a microwave oven, and this cooking oil is retained on the heat-resistant porous plate. In addition, the heat-resistant porous plate is maintained at a high temperature due to the heat insulation layer provided on the outside of the bottom of the container.
High heat is applied to the food placed thereon, and the food can be heat-treated in a roasting or frying state, allowing the microwave oven to be usefully used as a cooking device.
