Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a food storage container for cooking, and particularly to a container used for cooking in a microwave oven.

[Conventional technology]

As a container for cooking food using a high-frequency heating device, a so-called microwave oven, it can be sold in a state where the food for cooking is stored, and it can be sold in a state where the food for cooking is stored in the microwave oven. There are things that can be heated.

When cooking food using this microwave oven, depending on the type of food, there are two methods: heating the food directly using the microwave's high frequency waves, and cooking while steaming the food using steam. I found a way to do that.

In the case of such foods for cooking, the cooking time varies depending on the type of food and the cooking method, and it is not possible to provide a uniform solution. This problem can also occur depending on the amount of water injected, and even if the microwave oven had a mechanism to adjust its operating time, it was not effective.

Therefore, when cooking in a microwave oven, it is not possible to reliably know when the cooking is complete, and the heating may be stopped before the food is cooked, or the food may be overcooked. was seen frequently.

[Problem that the invention attempts to solve]

In this way, with conventional cooking using this type of container, it is difficult to know when cooking is complete from the outside.
There is a risk of under-heating or over-heating, and in the case of steam cooking, it may not be steamed enough, or it may become watery due to over-steaming, making sure that the food is delicious and delicious. There were times when I was unable to cook.

The present invention was devised to solve the problems of the conventional examples mentioned above and to meet the demands.The present invention is designed to make it possible to know from the outside that the temperature inside the container has reached the appropriate temperature for completion of cooking. This is a technical issue.

[Means and actions for solving problems]

Hereinafter, the present invention will be described with reference to drawings showing embodiments of the present invention.

The cooking food storage container 1 according to the present invention is composed of a main body 2 for storing cooking food, a lid 3, and a working piece 5.

The lid body 3 is joined by a hinge 4 between its rear ends to open and close the main body 2.

The action piece 5 is formed into a sheet piece of heat-shrinkable material, and has one end fixed to the upper surface of the rear end of the lid 3 and the other end attached to the rear end of the main body 2. By fixing to the bottom surface, the hinge 4
The hinge 4 is assembled between the rear ends of the main body 2 and the lid 3, which are located further rearward than the main body 2, in a stretched state in a direction substantially perpendicular to the hinge axis.

Therefore, since the main body 2 is closed by the lid 3, when normal cooking is achieved and the temperature of the container 1 rises above a predetermined temperature as the food inside is heated, the radiant heat from the container 1 is Acting piece 5 acts as the main body.
will be heated. The heating of this working piece 5 is
This can also be achieved by blowing away excess steam generated by heating the food.

However, this working piece 5 is a sheet piece made of a heat-shrinkable material, and one end thereof is fixed to the upper surface of the rear end of the lid body 3, and the other end is attached to the rear end of the main body 2. The hinge 4 is fixed to the lower surface of the end.
Since the hinge 4 is assembled in a stretched state in a direction substantially perpendicular to the hinge axis at a position rearward of the hinge 4, the lid 3 or the main body of the operating piece 5 will be exposed to the above heat. The central portion that is not fixed to 2 contracts, and its tensile force opens the lid 3.

Since this phenomenon appears visually, it is possible to know when cooking is complete.

The thermal contraction temperature of the working piece 5 is set depending on the type of food to be stored, the purpose of cooking, etc.

That is, if you want to indicate the completion of cooking, you can set it so that it contracts when the internal temperature reaches a suitable target temperature or higher.

〔Example〕

The main body 2 and the lid 3 in the illustrated embodiment are molded into shell-shaped shapes from a predetermined synthetic resin material, and are designed to look like a shellfish opening when cooking is complete.

In addition, a seal piece 6 is attached to the upper end of the main body 2 to protect the stored food until the start of cooking. You can also leave it as is.

Furthermore, since the thermal contraction action of the action piece 5 is mainly due to radiant heat from the container 1, the temperature required to cause the action piece 5 to perform the contraction action does not have to be very high, and is approximately 80°C. Therefore, as the material for the working piece 5, a sheet made of synthetic resin such as nylon or oriented polyethylene terephthalate resin will be used.

If the entire area of the operating piece 5 were fixed to the lid 3 or the main body 2, the contraction would not work effectively to open the lid 3. Therefore, only both ends of the operating piece 5 are fixed. As shown in the embodiment shown in FIG. 3, if the hinge 4 is placed slightly closer to the front, the lid can be opened more reliably by contraction.

The simplest way to position the action piece 5 behind the hinge 4 is, for example, to form a rearwardly protruding portion on the rear end of at least one of the main body 2 and the lid 3. I think that the.

Note that the excess steam generated in the container 1 can be effectively discharged even without the contraction operation of the action piece 5 because the lid body 3 is slightly pushed up by the steam pressure of this excess steam.

[Effect of the invention]

As is clear from the above explanation, the food storage container for cooking according to the present invention makes it possible to reliably recognize from the appearance that cooking has been completed, so there is no possibility of overcooking or undercooking. It is easy to use, can be manufactured and sold at low cost, and exhibits many excellent effects.
