Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a food storage container for cooking, and more particularly, to a container that can be used to cook food in a microwave oven while the food is stored therein. It is.

[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. A separate table was prepared for placing the food on the food, and this table was used to heat and cook the food.

This device requires a dedicated mounting table for cooking food using a microwave oven, which poses a problem of complicating its use and operation of the microwave oven.

For this reason, containers are being used that are sold in a state in which the food to be cooked is stored and can be heated in a microwave oven while the food is stored therein.

[Problem that the invention attempts to solve]

However, since the container used to cook food using the conventional microwave oven described above is placed directly in the microwave oven,
The food to be cooked located at the bottom of the container is not heated sufficiently, resulting in uneven heating of the food and poor heating efficiency.
As with the conventional method, there was a problem in that a dedicated mounting table was required.

The present invention was devised in order to solve the problems and dissatisfaction with the conventional methods described above. The object of the present invention is to uniformly heat the entire cooking food stored in the container by placing it in a floating state within the container, and to improve the heating efficiency for the cooking food. That is.

[Means for solving problems]

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

The food storage container for cooking according to the present invention comprises a container 1 for storing food for cooking, and a box-shaped frame 5 with at least the front side open, which is made of a heat insulating material such as cardboard and houses the container 1. When the cylindrical wall portion 2 of the container 1 is inserted into the top wall 7 of the frame 5, the opening edge abuts the container 1 from below and supports the container 1 in a suspended manner. 8, and further provided with bending lines 11 at the front end portions of both side walls 6 of the frame body 5 for bending the front end portions inwardly over the entire height range of the side walls 6 to form reinforcing ribs 10. It is composed of

The container 1, like a normal container, is constructed by combining a container body in the shape of a cylinder with a bottom and a lid body that opens and closes the top opening of the container body.

A frame 5 for storing the container 1 is basically in the shape of a simple box, and the container 1 can be taken in and out of the frame 5 through the open front surface of the frame 5.

An opening 8 formed in the top wall 7 of this frame 5
The container 1 is held in a suspended shape by the top wall 7, but its planar shape is not limited to a circular shape. It may be any shape as long as it can be achieved.

When the container 1 is held suspended by the frame 5, the bottom 3 of the container 1 is located sufficiently higher than the bottom wall 9 of the frame 5, so that the frame 5 cannot be placed on the mounting table. When used as a microwave oven, the container 1 will be located in a microwave oven in a state where it is raised from the bottom surface of the interior space of the microwave oven.

[Operation] Since the present invention is constructed as described above,
At the time of sale and storage, the container 1 is kept housed within the frame 5.

In this state, that is, the state in which the container 1 is stored and held within the frame 5, the container 1 which is the main body of the product is
is protected by the frame 5,
Since the frame body 5 functions as a cushioning material, the container 1 is not damaged and the container is easy to handle.

When used for cooking, the container 1 is taken out from the inside of the frame 5, and the portions of both side walls 6 forming the open edges of the frame 5 are bent inward along the bending line 11 to form the reinforcing ribs 10. is formed, and when the container 1 is mounted on the frame 5, this container 1
The frame body 5 is provided with mechanical strength that allows the frame body 5 to sufficiently withstand the load of .

Once the reinforcing ribs 10 have been formed, the container 1
is inserted into the opening 8 from above.

When the container 1 is inserted into the frame 5 from above, the opening edge of the opening 8 abuts a part of the container 1 from below, preventing the container 1 from further entering the frame 5. , supports the container 1 from below and supports the container 1 in a hanging shape.

If the container is inserted into the microwave oven in this position, the container 1 will be located in a state where it is raised from the bottom of the internal space of the microwave oven, so that the high frequency waves of the microwave will be stored inside the container 1. The food to be cooked will be irradiated almost uniformly from the surroundings, thereby achieving uniform heating of the food to be cooked and extremely good heating efficiency.

In addition, the frame 5 is made of a material such as cardboard that is not heated by high frequency so as not to interfere with the heating of the food inside the container 1, so it is difficult to remove the container 1 after cooking the food. In addition, if the container 1 is taken out by holding the frame 5, the frame 5 functions as a heat insulating material, which helps to safely and efficiently take out the container 1 from the microwave oven by hand.

〔Example〕

As shown in FIGS. 1 to 3, the container 1 in the embodiment is made of a predetermined synthetic resin material in a heat-resistant state, and the upper end of the cylindrical wall portion 2 is inverted and bent, and the container 1 is bent outward. It has a structure in which a flange 4 is integrally provided extending in the direction. A lid plate is attached with a seal to the upper opening of the cylinder wall 2, and is opened during or after cooking. The frame 5 is a box-shaped body made of cardboard or the like and whose entire surface is open, and its height is set approximately equal to the height of the container 1, and the opening 8 is located outside the flange 4 of the container 1. It is formed with a diameter smaller than the outer diameter of the cylinder wall portion 2, but larger than the outer diameter of the cylinder wall portion 2.

Further, the reinforcing rib 10 is formed by bending the front end portion of the side wall 6 inward at right angles as shown in FIG. 6 along the bending line 11 shown by the dotted line in FIG. By positioning the reinforcing ribs 10 in an upright position with respect to both side walls 6, greater reinforcing strength can be exerted.

Since the diameter of the opening 8 is larger than the outer diameter of the cylindrical wall 2 of the container 1 and smaller than the outer diameter of the flange 4, when the container 1 is inserted into the opening 8 from above, the opening 8 The opening edge of the top wall 7 abuts against the flange 4 from below, setting the insertion limit of the container 1 into the frame 5, and suspending the container 1 by supporting the flange 4 from below. Support it in the same way.

That is, the container 1 is supported with its bottom 3 raised above the bottom wall 9 of the frame 5 by the height difference from the upper end of the container 1 to the lower surface of the flange 4.

The shape of the container 1 is not limited to the shape of a cylinder with a bottom, but may be a triangular cylinder with a bottom as shown in FIG. 7, a square cylinder with a bottom, or a hexagonal cylinder with a bottom. It's okay to be.

Similarly, the shape of the frame 5 is not limited to the rectangular box shape, but may be a triangular tube shape with both upper and lower end surfaces closed, a cylindrical shape, or even a polygonal tube shape.

Furthermore, the portion of the container 1 that abuts against the opening edge of the opening 8 is not limited to the flange 4, and for example, as shown in FIG. By forming the opening 8 to have a diameter equal to the outer diameter of the approximately central portion of the tapered cylindrical wall 2, the opening edge of the opening 8 is formed at approximately the central height of the cylindrical wall 2. As a result, the container 1 can be supported like a hanger using the cylindrical wall portion 2 of the container 1.

Furthermore, when the container 1 is composed of a container body and a lid, a flange is provided around the circumference of the lid that is firmly assembled to the container body, and a flange is provided on the flange provided on the lid. It may be made to perform the same function as the flange 4 shown in FIGS. 1 to 3.

[Effect of idea]

As is clear from the above description, the cooking food storage container according to the present invention can be obtained by simply changing the assembly form of the container and frame, which are its constituent members, that is, by removing the container from the entire opening of the frame. By simply inserting it into the opening in the top wall, it is possible to uniformly heat the stored cooking food in the microwave oven and improve the heating efficiency, and this uniform heating of the cooking food improves the microwave oven. Since this can be achieved without having to heat the microwave oven, the types and range of foods that can be cooked in this microwave oven can be greatly expanded without being affected by the functionality of the microwave oven. This makes it possible to safely and effectively take out the cooked container by hand from the microwave oven, and since this frame acts as a cushioning material for the container, the container can be easily removed during distribution and storage. It exhibits many excellent effects, such as being able to safely protect the body, making it easy to handle, being easy to use, and being able to manufacture and sell at low cost. Furthermore, since reinforcing ribs can be formed at the open ends of both side walls of the frame, the mechanical strength of the frame is improved and can sufficiently withstand the load of the loaded container.
