Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a food storage container for cooking, and more particularly, to a container that can steam food in a microwave oven while the food is stored therein. It is something.

[Conventional technology]

When cooking food using a high-frequency heating device, a so-called microwave oven, a container containing the food is installed with the intention of eliminating uneven heating of the food and improving heating efficiency. Instead of preparing a separate stand for placing the food and cooking the food using this stand, the structure of the cooking food storage container itself can be improved so that the food can be stored as is. This makes it possible to achieve uniform heating and improve heating efficiency.

[Problem that the invention attempts to solve]

In this way, conventional food storage containers for cooking using a microwave oven can achieve uniform heating of the stored food and improving heating efficiency, but the cooking food stored in such containers Food products are limited to those that are directly heated, and they are not suitable for storing foods that are cooked by steaming.

In the case of such foods that are cooked by steaming, rather than cooking by directly irradiating the food with high-frequency waves from a microwave oven, steam is generated by simultaneously heating stored water, and the steam is heated. This means that you will be cooking while steaming.

However, when irradiating the same level of high frequency to food and water stored in a container, the heating efficiency of the food is much higher, and for this reason, the heating efficiency of the food is much higher than that of water, Not only does the cooking of the food result in overheating of the food to be cooked, but also the inconvenience that the surface portion of the food to be cooked that has been linearly heated is thermally hardened.

In addition, when steaming food, a large amount of steam is generated inside the container, but this steam is effectively guided to the food, and only the excess steam is discharged to meet the needs of steamed food. A steam atmosphere must be maintained.

In the case of conventional microwave oven containers, insufficient consideration was given to the above-mentioned points, and as a result, there was a problem in that good steaming of food for cooking could not be achieved.

The present invention was devised to solve the problems and dissatisfaction with the conventional examples described above.
Fitted into the main body that stores water, the steam generated by heating the water in the main body spreads uniformly within the medium container, and the food to be cooked in the medium container is heated as directly as possible. The purpose is to prevent the steam from steaming and quickly discharge excess steam to properly balance the heating of the food and water, so that good steam cooking can be achieved. .

[Means 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 according to the present invention is composed of a bottomed cylindrical main body 1 for storing water, an inner container 5 for storing cooking food therein, and a lid body 14.

The main body 1 is a bottomed cylindrical body with an outer flange 4 provided on the upper end of a peripheral wall 2, and the inner container 5 has a bottom wall 7 with a plurality of steam holes 8 formed therein. A cylindrical wall 6 with a small height is erected, a flange 9 is provided around the upper end of the outer peripheral surface of the cylindrical wall 6, and a frame ring 9' is attached to the outer peripheral end of the flange 9 through a cutting groove 10. The metal seal lid 12 is integrally installed in an extended form, and the peripheral edge of the lower surface of the metal seal lid 12 is adhered to the upper surface of the frame ring 9'.
Reference numeral 4 denotes a state in which the inner container 5 and the main body 1 are assembled into a combination, and the peripheral edge portion of the inner container 5 is lightly held between the outer flange 4 and the outer flange 4.

Then, the flange 9 and frame ring 9' of the middle container 5 described above are stacked on the upper surface of the outer flange 4 of the main body 1 described above, and the middle container 5 is fitted and assembled into the main body 1.

In this case, the cylindrical wall 6 of the medium container 5 is the main body 1 described above.
The height of the inner container 5 is smaller than that of the peripheral wall 2 of the inner container 5.
When the body 1 is inserted into the main body 1, it is held like a hanger, and the water stored in the main body 1 reaches a position lower than the lower end of the middle container 5. Water should not get inside.

[Effect]

Since the present invention is structured as described above,
At the time of sale and storage, the inner container 5 is fitted into the main body 1, and the lid 14 is closed and maintained in the assembled state.

When these parts are assembled, the inner container 5, which is the main body of the product, is protected by the main body 1 and the lid 14. Since the main body 1 functions as a cushioning material, the inner container 5 is protected by the main body 1 and the lid 14. 5, the container is easy to handle, and the upper end is closed by a metal seal lid 12, which prevents tampering with the food inside before use. be able to.

When used for cooking, the medium container 5 is removed from the main body 1 and the frame ring 9' of the medium container 5 is removed.
is separated from the flange 9 at the separation groove 10 to open the upper surface of the inner container 5.

Since the lower surface of the peripheral edge of the metal seal lid 12 is adhered to the upper surface of the frame ring 9', by this separation, the frame ring 9' is adhered to the peripheral edge of the lower surface of the metal seal lid 12. The frame ring 9' then functions as an aggregate for the peripheral edge of the metal seal lid 12. Furthermore, if an attempt is made to tamper with the food to be cooked inside, this separation must be performed, and repair is difficult, so tampering can be prevented.

Now, after opening the upper surface of the inner container 5 as described above, a predetermined amount of water is stored in the main body 1, the inner container 5 is fitted into the main body 1 again, and the flange 9 is placed on the outer flange 4 of the main body 1. and then a metal seal lid 12
is placed on the outer flange 4 and the flange 9, and the lid 14 is covered again.

In this position, since the separation groove 10 portion is separated, a passage 11 is formed between the flange 9 and the frame ring 9'.

In this position, the container is placed on the turntable in the microwave oven, etc., and the microwave oven's high frequency waves are irradiated almost uniformly from all directions to heat the water in the main body 1 and evaporate it. This steam enters into the medium container 5 through the numerous steam holes 8 in the bottom wall 7 of the medium container, and causes the food to be cooked inside to become stale.

A portion of the excess steam sent into the inner container 5 pushes up the metal seal lid 12 due to the steam pressure, thereby forming the passage 1.
The other part condenses on the inner surface of the metal seal lid 12, falls, and returns into the main body 1 through the steam hole 8.

When the water in the main body 1 is heated by the high frequency, the cooking food in the medium container 5 is heated by the metal seal lid 1.
2, the high frequency waves are unlikely to directly irradiate the food to be cooked, and the high frequency waves reflected by the metal seal lid 12 heat the water inside the main body 1 from the sides and below. Therefore, the heating of the food to be cooked and the heating of the water are performed in a well-balanced manner, and steaming cooking can be accomplished efficiently and deliciously.

Further, when the pressure of the steam generated in the main body 1 exceeds a preset pressure, the lid 14 is slightly pushed up by the pressure of this steam, and there is a gap between the lid 14 and the main body 1. Excess steam is discharged through the gap formed, thereby causing the body 1
The inside of the medium container 5 is maintained at a substantially constant temperature and vapor pressure.

〔Example〕

The main body 1 in the illustrated embodiment is thermoformed from a predetermined synthetic resin material, and has an outer flange 4 integrally provided by bending the upper end of a substantially cylindrical peripheral wall 2 outward. Bottom plate 3
An upward step 2a is formed on the upper inner periphery of the peripheral wall 2 to serve as a guideline for the upper limit for filling water.

The middle container 5 is molded by injection molding from a predetermined synthetic resin material, and has a wide flange body integrally provided by bending the upper end of a short cylindrical tube wall 6 outward. A separation groove 10 is provided to form a flange 9 and a frame ring 9', and a bottom wall 7 is connected to the lower end of the cylindrical wall 6. A large number of holes are opened at equal intervals so that the air bubbles rise evenly into the middle container 5.

The diameter of the upper end of the steam hole 8 is larger than that of the lower end,
The tapered shape allows water that has condensed and fallen to return smoothly into the main body 1 to prevent the food to be cooked from becoming watery. Consideration has been given to minimizing it as much as possible.

Further, a seal strip 13 is provided around the outer periphery of the cylindrical wall 6, and when the container 5 is fitted into the main body 1, this seal strip 13 comes into tight contact with the inner periphery of the main body 1.
The steam generated inside is sent into the middle container 5 through the steam hole 8 without waste, and the middle container 5 is prevented from floating due to steam pressure.

The frame ring 9' remains attached to the lower surface of the periphery of the seal lid 12, which is formed of metal such as aluminum foil, and functions as an aggregate. sexual seal lid 12
It does not curl up and get stuck, and the unevenness effect is good.

Next, the lid body 14 is thermoformed with a predetermined synthetic resin material, and a hanging cylinder 16 is integrally provided on the periphery of the top plate 15.
It has a structure in which a bending part 17 that bends inward is provided in a part of the structure.

In the assembled state, the lid body 14 lightly holds the peripheral portion of the inner container 5 between it and the outer flange 4.

Therefore, even if the metal seal lid 12 and the lid body 14 are lifted up by the steam during cooking, they will not come off, and the seal lid 12 will be pushed up by the generated steam pressure, so that the passage will be closed. 11 and the space between the outer flange 4 and the lid body 14, excess steam is discharged through a restricted ventilation path, and by limiting the area of this ventilation path, the inside of the main body 1 is maintained at an appropriate steam pressure. maintain it.

[Effect of idea]

As is clear from the above description, the cooking food storage container according to the present invention can successfully steam the stored cooking food in a microwave oven simply by separating the metal seal lid of the inner container, which is a component of the cooking food storage container. It also maintains a good heating balance between water and the food to be cooked, allows excess steam to be discharged smoothly, and maintains the appropriate steam pressure within the container, making it possible to achieve delicious steamed cooking. Since the main body, which is the water storage part, acts as a cushioning material, the inner container can be safely protected during distribution and storage, and it is easy to handle.It is also easy to use, and can be manufactured and sold at low cost. It has many excellent effects, including the ability to
