Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for heating food for microwave ovens, and more particularly, to heating and cooking food for cooking stored in a package using a microwave oven, by removing an outer lid of a container and keeping it as it is. The present invention relates to a package of food for heating a microwave oven, which can be cooked without being heated to a boiling state even when heated.

[0002]

2. Description of the Related Art A package devised so that food can be heated while being stored in a container in a microwave oven or a frozen product thereof can be thawed is described in, for example, Japanese Utility Model Laid-Open Publication No. 1-76468, and the like. .

[0003]

However, in these conventional packages, since the food stored in the container has been cooked once, it is only necessary to warm the food when eating, and it is necessary to heat the food for a long time. It does not require boiling cooking. Therefore, for example, semi-cooked products such as fast-cooked rice and foods requiring cooking (hereinafter, also referred to as cooked foods) are stored in the container of the package, and when making porridge or porridge, etc. However, when cooked for a long time in a microwave oven, there is a problem that the stored food and its broth are spilled or scattered due to the boiling, so that the inside of the microwave oven is not only stained, but also it is not possible to perform satisfactory cooking.

The present invention has been made in order to solve the above problems, and even when food stored in a container requires long-time heating cooking, spilling of boiling juice or the like due to boiling during cooking is performed. It is an object of the present invention to provide a package of a food for cooking by heating in a microwave oven, which can be cooked while suppressing heat scattering. In addition, the most suitable food for microwave cooking according to the present invention is processed rice which can be cooked in about 1/2 the heating time of what is generally called "quickly cooked rice" or raw rice as a main ingredient. And porridge, porridge, risotto, etc., which are cooked by adding various ingredients thereto. However, not limited to these,
All of the prepared foods that are cooked on a direct heat in a pot or the like correspond to this.

[0005]

In order to achieve the above object, the present inventor has set forth a container main body, an inner lid covering an opening below the opening surface of the main body opening, and a container main body opening. An outer lid that covers the inner lid, wherein at least one or more depressions are provided on the surface of the inner lid, and a through-hole is formed in the surface of the inner lid and / or the bottom surface of the depression, and the container Provided is a package of food for heating and cooking, wherein the food for cooking by microwave is stored in the main body. By adopting such a structure, the broth or the like spouted and spilled out of the container main body by heating by the microwave oven is transmitted from the surface of the inner lid to the through hole of the surface and the bottom through hole of the hollow portion and into the container again. It is refluxed and does not overflow out of the container. At this time, if the surface of the inner lid is formed to be inclined downward from the periphery to the center, the broth spouted from the container by boiling can be returned to the container more smoothly and repeatedly, so it is good to eliminate spills Cooking can be done. Therefore, if the food for microwave cooking is, for example, only fast-cooked rice processed for rice cooking, it can be quickly returned to the container without spilling a large amount of broth or bubbles spouting during heating and cooking. It can be cooked as delicious porridge or cooked rice.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a package A of food for cooking by heating in a microwave oven according to the present invention will be described with reference to the drawings of an embodiment. Figure 1
In the figure, reference numeral 1 denotes a container body which is made of a heat-resistant synthetic resin such as foamed polypropylene, polystyrene, polyethylene phthalate (PET), or a water-resistant paper container and has an open surface and is formed in a substantially cylindrical body, and has an opening thereof. On the inner surface, a step portion 3 for covering an inner lid 2 to be described later is formed, and further provided with a sealing portion 10 connected to the step portion 3 for covering and sealing the opening with an outer lid 4. Further, as will be described later, a frame portion 8 is formed on the peripheral edge of the inner lid 2 so as to be slidably fitted into a rising portion 7 provided between the step portion 3 of the container body 1 and the sealing portion 10.
The surface of the inner lid 2 is formed by a flat portion 6 which is slightly inclined from the peripheral edge to the center, but is formed flat as a whole, and a recess 11 provided in the center of the flat portion 6. ing. In addition, a through hole 5 is formed in the bottom of the recess 11.
Has been drilled. Here, the total area of the through holes 5 is set to about 5% of the surface area of the flat portion 6. If the total area of the through hole 5 is set to be 1% to 10% of the surface area of the inner lid 2 and is smaller than 1%, the squirted liquid or the like is easily clogged in the through hole 5 and hardly returns into the container body 1. If it is larger than 10%, the heating efficiency is reduced and it becomes difficult to cook delicious rice. The inner lid 2 thus formed is placed on the step 3 provided inside the container main body 1 so that the peripheral edge of the flat portion 6 covers the opening below the opening surface of the opening of the main body 1. I do.

In the case of this embodiment, the inner lid 2 is formed in the same substantially circular shape as the opening of the container body 1, and the recessed portion 11 is formed at a substantially central portion of the inner lid 2 as described above. However, a plurality of such depressions 11 may be provided and the through holes 5 may be formed in the respective bottom surfaces. In addition, the through hole 5 is formed in the recess 1.
In addition to 1, a hole may be formed in the flat surface portion 6 of the inner lid 2. In addition, the opening of the container body 1 of this embodiment has a substantially circular shape, but is not limited to this, and may have a square, rectangular, or other polygonal shape.

In the embodiment of the present invention, for example, fast-cooked rice 12 and other ingredients 14 are stored as microwave-heated food in the above-described container body 1, covered with an inner lid 2, and covered with an outer lid 4. And sealed to make it a product for porridge. In use, the cover of the outer lid 4 is removed, an appropriate amount of fresh water is poured into the container main body 1, heated by a microwave oven, and cooked.
At this time, a large amount of broth and water bubbles which are generated during the cooking of the rice and are likely to be spilled out are passed through the through holes 5 formed in the inner lid 2.
Once squirted from the inside of the container to its upper part, it is blocked by the peripheral frame 8 of the inner lid 2 and does not overflow out of the container body 1, but travels through the through-hole 5 formed in the inner lid 2 again. It is returned into the container body 1. As described above, during heating in the microwave oven, the same action is repeated to perform processing such as rice cooking, so that no spillage occurs.

FIGS. 2 to 5 show another embodiment of the package A for heating and cooking a microwave oven according to the present invention. FIGS. 2 and 3 are sectional views showing a state where an outer lid 4 is attached and a state where the outer lid 4 is removed. It is a figure and the cross section direction is a XX line cross section of FIG. FIG.
5 is a perspective view showing a state where the outer lid 4 is removed, and FIG. 5 is a perspective view showing a state where the outer lid 4 and the inner lid 2 are removed.

In FIG. 2, the inner lid 2 has its peripheral edge placed on the step 3 of the container body 1, and the peripheral edge thereof has a frame portion 8 rising therefrom and a front end horizontal portion 13 of the frame portion 8 downward. A falling frame portion 8 'formed by bending and a flange portion 9 formed by horizontally bending the lower end of the falling frame portion 8' outward are formed. At this time, the outer peripheral surface of the falling frame portion 8 ′ is formed in an outer peripheral shape that can be fitted to the rising portion 7 of the container body 1 by turning the inner lid 2 upside down. Since the other embodiment of the present invention shown in FIGS. 2 to 5 has such a structure, the inner lid 2 is formed by grasping the frame 8 and the falling frame 8 'at the peripheral edge thereof with a fingertip. , Can be easily attached to and detached from the container body 1. When distributing as a product, the inner lid 2 is turned upside down in FIG. 2 so that the falling frame 8 ′ is slidably fitted to the rising part 7 of the container body 1. The entire volume can be covered with the outer lid 4 in a compact manner. The structures of the hollow portion 11, the through-hole 5, the flat portion 6, and the like of the inner lid 2 are the same as those in the previous embodiment, and thus the description thereof will not be repeated. Also, the same reference numerals in the drawings denote the same parts as in FIG.

[0011]

As described above, according to the present invention, since a through hole is formed in the surface of the inner lid and the bottom of the depression provided in the inner lid surface, foods that need to be cooked in a microwave oven can be prepared. Even if the heat treatment is performed for a long time, the broth and water bubbles blown up by boiling can be returned to the container main body from the through-holes, so that cooking can be suppressed while preventing spillage. Therefore, not only can the cooked food be finished to a delicious taste, but also the microwave oven can be kept clean without soiling.
