As synthetic pulp, for example, those made of thermoplastic resins such as polyethylene, modified polyethylene, and polypropylene are preferably used.

The cover sheet 320 may be a paper foil coated with silicone on one or both sides.

The method of preventing juice stagnation of the present invention utilizes the capillary principle.

When the moisture-absorbing cloth 310 is inserted between the paper foil 300 and the covering paper 320, the meat juice generated during cooking is absorbed by capillary action between the paper foil 300 and the covering paper 320 and is absorbed into the moisture-absorbing cloth (310). 310), the meat juice absorbed into the moisture absorbent cloth also plays the role of insulating cooked food while it is consumed, thereby keeping the food (food) warm for a long time. In the present invention, a moisture-absorbent cloth is inserted under the cover to prevent direct contact with food, and the moisture-absorbent cloth is made of 100% natural pulp, so it is much safer and more hygienic than the existing method of inserting an absorbent into food.

When pork belly or the like is placed in the container of the present invention and heated in a microwave oven, the food material itself generates heat by the microwave and is heated from the inside, and even the raw food material is cooked in a short time. At this time, water vapor is generated from the food material, and a constant water vapor atmosphere is created in the container wrapped with two layers of the first wrapping and the second wrapping and prevents the food material from drying excessively. That is, when the pressure inside the container exceeds a certain level, the steam discharge slits 123 act to lower the pressure inside the container and maintain a constant pressure. Additionally, strictly speaking, heating meat is accompanied by an effect similar to steaming the food material by heating the moisture inside the food material using microwaves and trapping the evaporated water vapor in the container.

Therefore, according to this cooking method, contents such as pork belly can be cooked similar to meat grilled over an open flame without damaging the good taste or nutrients by simply heating frozen raw food ingredients in a microwave oven.

Another aspect of the present invention for achieving the above-described object relates to a convenient meal that can be easily cooked on the spot without smoke using a microwave oven in which cooking food or food is packaged in the smokeless disposable cooking container of the present invention described above. The food or food for cooking may be seasoned or smoked. These convenience foods can be sold as convenience store meals, portable convenience meals, ready meals, meal kits, etc.

The convenience food of the present invention can be packaged in a frozen state such as grilled pork belly, chicken, duck, beef, etc. This makes it possible to store and distribute fresh meat ingredients for a long period of time. In particular, if an appropriate cooling method is adopted, loss of moisture and nutrients from food ingredients can be prevented. In the convenience food of the present invention, not only meat but also seafood such as stir-fried squid, stir-fried octopus, grilled fish, and stewed fish can be packaged in a frozen state. In addition, vacuum packaging prevents the invasion of harmful bacteria and makes it possible to keep the quality fresh for a long period of time.

The convenience food of the present invention can be thawed and cooked simultaneously using a microwave oven when cooking. For example, you can complete grilled pork belly in about 6 minutes by repeating 2 minutes of cooking followed by a 10-second rest three times. Cooking time can be adjusted appropriately depending on the output of the cooking utensil.

The manufacturing process of the convenience food of the present invention will be described.

Referring to Figure 3, first, paper foil 300 is laid on the inner box 200 of paper material, and meat such as pork belly is placed on the paper foil 300. Meat such as Samgyeolsal can be folded or rolled to prevent it from shaking during the distribution process. Depending on the characteristics of the product, meat can be seasoned with herb salt or added with smoking agents. The paper foil 300 is manufactured in a larger shape than the inner box 200, and is intended to contain meat products and then fold to cover the meat. After covering the paper foil, it is first sealed with a food packaging film to form the first wrapping 400, and a cut line is formed in the center to form a steam outlet. These cut lines are to prevent explosion due to water vapor during cooking and to form a vapor separation membrane. At this time, the food packaging film that can be used may be a polyethylene-based food packaging film or a low-density polyethylene film obtained by high-pressure polymerization. Alternatively, the food packaging film may be a film in which a film formed of a polypropylene resin composition is inserted between the inner and outer layers.

Next, the odor absorption cloth 500 is covered over the first wrapping 400. After arranging the odor absorption cloth, a second wrapping 600 is performed overall. The second wrapping 600 is for secondary oil vapor collection and distillation and to prevent food explosion. After forming the second wrapping, the packaged product is placed into the outer box 100.

When cooking the convenience food of the present invention, the tear line 125 formed on the upper surface of the outer box 100 is cut to form a central steam outlet before putting it in the microwave oven. Water vapor can be trapped in the first wrapping (400) and the second wrapping (600). Cooking time in the microwave can be adjusted depending on the type or amount of meat. For example, for 300g of pork belly, cook in the microwave for 2 minutes, rest for 10 seconds, cook for 2 minutes, rest for 10 seconds, and cook for 2 minutes. You can cook for about 6 minutes with a 10-second rest. At this time, the radial steam discharge slit 123 is erected upward, and the hot oil vapor in the outer box 100 is cooled and restored to its initial flat state. After confirming that the divided surfaces by the radial vapor discharge slit 123 of the outer box 100 have been restored to their original state, the microwave oven door is opened.

When eating after cooking, open the outer box (100), remove the first wrapping (400), second wrapping (600) and odor absorbing cloth (500), open the paper foil (300), and eat the cooked food. do. While eating, the fat or juice that leaks from the food during the cooking process is absorbed by the means to prevent the juice from stagnating, so you can enjoy it refreshingly without discomfort while eating. After eating all the food, the accumulated oil and remaining food waste are wrapped and disposed of in the paper foil 300, and the outer box 100 and inner box 200 are paper materials, so they can be classified as recyclable waste and recycled.
