Description

  The present invention relates to a microwave cooking container that is suitable for cooking various foods, in particular, soups such as soup in a microwave oven and can be used repeatedly.

When cooking with a microwave oven using a non-disposable container such as a mug, the container is generally covered with a wrap or the like and heated. However, when the pressure in the container rises, the wrap and the like may come off and the food material may scatter, or sudden noise may be produced suddenly during cooking due to bumping. In addition, when heated without a lid, the inside of the container is not sealed, so the food cannot be steamed, and when the broth or the like boils, it may splash outside the container and contaminate the inside of the microwave oven. is there.
Therefore, there is a container with a hermetic lid of Patent Document 1.

  The invention of Patent Document 1 is a container with a lid that enhances hermeticity when the lid is closed, and a protruding edge is formed in the opening of the inner wall surface of the container, and the lid is opened during cooking in a microwave oven. It does not come off easily. In addition, an opening / closing knob that vents the air in the container is provided at the top of the lid. By removing the air in the container after heating, the lid can be easily opened even when the pressure in the container decreases due to cooling after heating. Can be opened.

  However, the invention of Patent Document 1 cannot prevent the occurrence of bumping because the pressure in the container cannot be adjusted during cooking in a microwave oven. In addition, when cooking is performed by opening the opening / closing knob part of the lid, there is a risk that the soup will be spilled from the knob part and the inside of the microwave oven will be soiled.

  Therefore, the present invention is capable of adjusting the pressure inside the container during cooking in a microwave oven, and can cook food while preventing spilling of simmered juice, removal of the lid and bumping, etc. The purpose is to provide a container for use.

The present invention is a container for microwave oven cooking comprising a cup-shaped container body made of ceramic, glass or hard plastic, a lid made of a plastic sheet and a cap,
The lid includes an annular recess and a lid recess at the top, a lid flange at the bottom, and a lid groove that protrudes upward from the lid flange,

The above problems have been solved by a microwave cooking container in which steam in the container is discharged by the lid opening and the lid steam discharge groove .
Here, the “cup shape” is the same shape as a commercially available cup, mug, or the like, and includes a shape in which the edge is slightly raised, including the case where the edge is slightly inclined outward.
Further, as described in claim 5 , the outer diameter of the upper flange of the recess for locking the packing is made shorter than the outer diameter of the lower flange, or the packing is horizontally attached to the mounting portion of the adapter as in claim 6. By providing the container with being inclined upward with respect to the direction, the lid body is easy to close and is difficult to come off.

According to the present invention, when the vapor pressure increases, the cap is automatically pushed upward, and the water vapor generated in the container is automatically discharged by the lid opening and the cap flange or the vapor discharge groove of the lid. Therefore, there is no fear that the fitting between the container main body and the lid body is disengaged due to the vapor pressure, or the contents are easily scattered outside the container, so that the inside of the microwave oven is not contaminated even when the soup such as soup is heated.
In addition, after cooking and heating, the cap returns to the same fitted state as before cooking, and as before cooking, the container main body and the lid, and the lid and the cap are stably fitted by the fitting portion. No food juice or liquid is leaked, and no dust or dirt gets inside the container.
Furthermore, by interposing an adapter with a packing between the container and the lid, it is possible to adjust the pressure inside the container while increasing the adhesion between the container and the lid, and the difference in the size of the opening of the container body Can also be supported.

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

First, the configuration which is the premise of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, a microwave cooking container (hereinafter sometimes simply referred to as “container”) 10A includes a container main body 1a, a lid 2a, and a cap 3, and includes a container main body 1a. Includes a food storage unit 11, the lid 2 a includes an annular recess 21 and a lid recess 22 in the upper part, a lid flange 23 a in the lower part, a lid groove part 24 protruding upward from the lid flange 23 a, and the cap 3 The cap fitting part 33 is provided on the side surface and the flange 31 is provided on the upper part.
The container body 1a, the lid 2a, and the cap 3 are integrated by fitting the edge 12a of the container body 1a and the lid groove 24, the lid recess 22 and the cap fitting portion 33, and the annular recess 21 and the flange 31, respectively. It becomes.

  Since the height of the annular recess 21 is lower than the height of the lid upper surface 25, the sealing property of the cap 3 is enhanced, and as a result, the steaming effect by steam is improved. Since the end of the knob 32 provided on the outer periphery of the flange 31 is always slightly lifted upward, the cap 3 can be easily removed when cooking is finished.

When ingredients are put in the microwave cooking container 10A and put in the microwave oven, the food and the broth in the container 10A boil by heating to generate steam, and the vapor pressure increases. When the vapor pressure increases, the vapor remains in the state shown in FIG. 3B, and the vapor is stepped from the lid opening 26 opened at the bottom of the lid recess 23 (the lowermost portion is always open). And the flange 31 of the cap 3 is pushed up by elastic deformation and passes through the gap between the annular recess 21 and the flange 31 of the cap 3 to the outside.
When the vapor pressure further rises, the cap 3 itself is automatically pushed upward, and vapor discharge is promoted (see FIG. 3A).
When the heating is finished, the temperature inside the container 10A is lowered and the internal pressure of the container 10A is lowered, so that the cap 3 once pushed up automatically fits into the lid 2a, and the flange 31 is again attached to the lid 2a. It closely adheres to the annular recess 21 and returns to the state shown in FIG. 3B to seal the inside of the container 10A.
In FIG. 1, the number of the steam discharge grooves 27 is four, but the number is not particularly limited.

The container body 1a may have the same shape as a commercially available cup or the like, and no special processing is required. The material can be used repeatedly, and is made of ceramic, glass or hard plastic. Furthermore, if the handle 13 is provided, even if the container body 1a is hot at the end of heating, there is no hindrance to carrying it, especially when cooking soup or other soup, without transferring it to another container. You can eat and drink as it is.
The lid 2a and the cap 3 are made of, for example, a thermoforming method such as pressure forming or vacuum forming using a heat-resistant plastic sheet such as expanded polystyrene (OPS), heat-resistant stretched polystyrene (heat-resistant OPS), or polypropylene. It can be formed by injection molding using a chip as a material.
The container body 1a and the lid body 2a are not limited to the illustrated shapes, and may be quadrangular or the like.

Next, with reference to FIG. 4, a different part from FIGS . 1-3 of the other structure used as the premise of this invention is demonstrated .

Although the container main body of FIGS. 1-3 does not give the edge | side process to the edge, there exists a case where it is desirable to raise the adhesion degree of the container main body 1b and the cover body 2a, when improving the steaming effect.
In such a case, by making the shape of the longitudinal section of the edge 12b of the container body 1b circular or elliptical, the degree of adhesion between the container body 1b and the lid 2a is increased, and the lid 2a is detached from the container body 1b. It can be made difficult (see FIG. 4A).
Further, as shown in FIGS. 4B and 4C, the shape of only one side of the longitudinal section of the edge 12b of the container body 1b may be circular or elliptical.

The first embodiment of the present invention will be described below with reference to FIG.

The container shown in FIGS. 1 to 3 has a structure in which the container main body 1a is covered with the lid 2a. However, when the container main body is made of glass or ceramic, the size of the opening of the container main body 1a is somewhat different. There may be a gap between the main body 1a and the lid 2a.
Therefore, by providing the adapter 4a having the packing 45a between the container body 1a and the lid body 2a, the gap between the container body 1a and the lid body 2a can be eliminated, and the lid body 2a can be brought into close contact with the container body 1a. Thereby, the sealing effect of container 10B increases and the cooking effect including the steaming effect at the time of microwave oven heating can be heightened more.

The adapter 4a is provided in the opening 41 provided in the upper center, the mounting portion 43a extending downward from the inner periphery of the adapter flange 42a, the adapter fitting portion 44a extending upward from the adapter flange 42a, and the mounting portion 43a. A packing 45a is provided.
The packing 45a is an elastic body having a circular cross-sectional shape, but may have an elliptical shape or other shapes. Among elastic materials, silicon rubber having excellent heat resistance and water resistance is preferable.
The lid body groove portion 24 and the adapter fitting portion 44a are fitted, and the container flange 1a is brought into contact with the container body 1a, whereby the container body 1a, the adapter 4a, and the lid body 2a are integrated. At this time, since the packing 45a is in close contact with the inner peripheral surface of the container body 1a, there is no gap between the container body 1a and the lid body 2a, and a high sealing effect is obtained. Therefore, the lid 2a is not detached from the container main body 1a due to the vapor pressure. Therefore, it is possible to prevent food juice from splashing and dust and dust from entering the container.

Hereinafter, with reference to FIG. 6, a different part from 1st Embodiment is demonstrated about 2nd Embodiment of this invention.

  As shown in FIG. 6, in the adapter 4b of the present embodiment, the mounting portion 43b extends downward from the outer peripheral side of the adapter flange 42b unlike the third embodiment, and the packing 45b is the outer periphery of the container body 1a. It is provided in close contact with the surface. Even if the packing 45b is brought into close contact with the outer peripheral surface of the container main body 1a as in the present embodiment, and the container 10C is in a sealed state, the same effect as in the second embodiment can be obtained.

Hereinafter, with reference to FIG. 7, a different part from 1st Embodiment is demonstrated about 3rd Embodiment of this invention.

In 3rd Embodiment, the cover body groove part is not provided but the cover body flange 23b and the adapter flange 42c fit, and the cover body 2b and the adapter 4c are integrated.
The mounting portion 43c extends vertically downward from the inner periphery of the adapter flange 42c. A flat recess 46 is provided on the inner periphery of the boundary between the adapter flange 42c and the mounting portion 43c over the entire periphery. Yes. The mounting portion 43c is provided with a packing locking recess 47 over the entire circumference. The packing 45c is a flat shape having a rectangular cross section, and is fitted in the recess 47 for packing locking.
In the present embodiment, when the lid 2b is attached to the container main body 1c, the packing 45c is in close contact with the inner peripheral surface of the container main body 1c. As a result, the same sealing effect as in the first embodiment can be obtained, and even when the difference in the size of the opening of the container body 1c is large, the lid body 2b is compared with the other embodiments in the container body 1c. It is stably fitted to the inner periphery of the.

As shown in FIG. 8, when the outer diameter of the upper flange portion 48a of the packing locking recess 47 is smaller than the outer diameter of the lower flange portion 48b, the contact area between the upper flange portion and the packing 45c is reduced. Since the packing 45c is easily deformed, the lid 2b can be easily mounted (see FIG. 8A). On the contrary, since the contact area between the lower flange portion 48b and the packing 45c is large, the lid 2b is difficult to be detached from the container body 1c (see FIG. 8B).
By doing so, the lid 2b does not easily come off from the container main body 1c, so that even if the lid 2b is held and the container is lifted up, the food in the container main body 1c may be spilled. There is no.

Hereinafter, with reference to FIG. 9, a different part from 3rd Embodiment is demonstrated about 4th Embodiment of this invention.

  As shown in FIG. 9, the mounting portion 43d may be provided with no packing locking recess, and the mounting portion 43d may be provided with the packing 45c inclined upward with respect to the horizontal direction. When the packing 45c is provided to be inclined upward, when the lid 2b is closed, since the packing 45c is upward, the friction with the inner peripheral surface of the container main body 1c is small and it is easy to close. On the contrary, when the lid 2b is opened, the friction between the packing 45c and the inner peripheral surface of the container main body 1c is increased, making it difficult to open. Therefore, even with the structure as shown in FIG. 9, the same effect as the structure shown in FIG. 8 can be obtained. In addition, the structure of FIG. 9 only requires the packing 45b to be mounted on the mounting portion 43b by inclining upward with respect to the horizontal direction without providing a packing locking recess, and thus the processing is simpler than that of FIG. There are advantages.

As described above, according to the microwave oven cooking container of the present invention, since the steam generated in the container is automatically discharged by the lid and the cap, the lid is detached from the container or the contents are the container. Even if the soup or other soup that easily scatters outside is heated and cooked, the inside of the microwave oven is not soiled, and dust and dust are not mixed inside the container. The container body may be the same as a commercially available glass, ceramic or hard plastic cup, and does not need to be specially processed to fit the lid.
In addition, providing an adapter with a packing between the container and the lid makes it difficult for the lid to come off the container, and even if there is a slight difference in the size of the opening of the container body, The degree of adhesion can be maintained.
Furthermore, it is possible to provide a structure in which the lid can be easily closed and not easily detached from the container main body simply by changing the packing attachment method.
