In addition to avoiding the presence of an acute-angled portion, a protruding portion is provided above the center of the bottom portion 1 so as to project below the bottom portion 1 at the time of pressurization, and to promote the heat flow that returns to its original shape after reaching a normal state. 3. A dish-shaped hermetic container for a microwave oven, characterized in that a protruding piece having a large number of small concaves and convexes is provided for removing the lid 7 at one corner of the lid 3 and the lid 7.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a dish-shaped hermetic container for microwave ovens, and more particularly to a hermetic container having good heat flow and having a ridge that also promotes heat flow protruding below the bottom when pressurizing.

[0002]

[Prior Art]

 Conventionally, a closed food container made of a material that can be reheated in a microwave oven has a flat bottom and has sharp corners between the bottom and sides and at the four corners. Are formed.

[0003]

[Problems to be solved by the device]

 However, in the conventional food-sealed container described above, heat is concentrated on the four corners or at the intersections of the bottom and sides due to the rectilinearity of the microwave for cooking in the microwave oven, and the entire container is not heated uniformly. There is a problem, and there is a problem that it takes time to be heated uniformly.

Further, there is a problem that the container is deformed due to a rapid increase in internal pressure due to heating. Further, there is a problem that it is not easy to remove the raised lid mounted on the dish-shaped container.

[0005]

[Means for Solving the Problems]

 The present invention is a dish-shaped container formed of a material that can be reheated in a microwave oven, and a raised lid that is detachably fitted and sealed in the dish-shaped container. Between the bottom and the sides that make up the container, and between the four perimeters of the sides are formed in a circular shape to prevent the presence of sharp edges, and to project above the center of the bottom below the bottom when pressure is applied. It is configured by providing a raised part that also promotes the heat flow that returns to the original shape after reaching normality, and a protruding piece part with multiple small irregularities for peeling off the lid at one corner of the container and the lid Then, the problem is solved.

[0006]

[Action]

 When a dish-shaped closed container that holds cooked prepared foods, etc. and is sealed with a raised lid is placed in the microwave oven and reheated, there is no sharp corner in the container and the bottom center By having a raised portion on the microwave oven, the microwaves for cooking can be spread all over the inside of the container, and the cooking time for reheating can be shortened by about half to eat.

Further, when the inside of the container is pressurized by the reheating, the raised portion projects below the bottom to soften the pressure and prevent the deformation of the container. It should be noted that this raised portion will elastically return to its original shape when the pressure is stopped.

Further, the lid to be mounted is tightly inserted into and closed from the edge of the container in order to make it hermetically sealed, but since the present invention is provided with a piece portion having a large number of small irregularities in one corner, it can be used as a finger rest. It can be easily peeled off and removed.

【Example】

 Embodiments will be described below with reference to the drawings.

A dish-shaped container 3 having a bottom portion 1 and a side portion 2 and having a rectangular shape in plan view is integrally formed. A circular curved surface 4 is interposed between the bottom portion 1 and the side portion 2 so that an acute angle portion is not formed, and a circular curved surface 5 is formed between each side portion 2 and 2 so that no acute angle portion exists.

On the center of the bottom part 1, a ring-shaped outer edge 6a formed in a small curved concave groove for bending and a rounded or quadrangular ridge 6 with a gentle curved surface are formed in the outer edge 6a. ..

When the internal pressure is increased and the bulging portion 6 is pushed, the bulging portion 6 is elastically bulged from the outer edge 6a to the base edge and projected below the bottom portion 1, and when the pushing is stopped, the bulging portion 6 is elastically restored to its original shape. Reference numeral 7 denotes a raised lid that is transparently formed of a transparent material. When the lid is fitted into the container 3, the inside of the container 3 is sealed by a known fitting and sealing means. Reference numeral 8 denotes a protruding piece for opening the lid, which is provided with a plurality of small irregularities 8a.

After the cooked food such as a side dish is housed in the container 3, the lid 7 is fitted to the container 3 for hermetically sealing and transporting, and the container is put in the microwave oven 9 at home or the like for reheating. Since there are no sharp corners in the container 3 and the ridges 6 that are bulged with a gentle curved surface on the center of the bottom part 1, the corners of the cooking wave of the microwave oven 9 are not concentrated, As the heat flow from side 2 over bottom 1 over ridge 6 in the bottom center occurs as indicated by the arrow in Fig. 1, the food product is reheated quickly and equally by heating from the center. Will be done.

The heat flow is promoted.

When the pressure in the closed container rises due to heating and pushes the ridge 6, the ridge 6 projects below the bottom 1 based on the outer edge 6a to relieve the pressure in the container 3 and When the internal pressure decreases with the end of heating and the pushing of the ridge 6 is released, the ridge 6 is elastically restored to its original shape. Therefore, the deformation of the container 3 is prevented.

As shown in FIG. 4, the closed container taken out from the microwave oven 9 can be easily and neatly peeled off by protruding and hooking the finger on the piece 8.

FIG. 5 shows a closed container according to the second embodiment, in which the outer edge 6a is not provided on the center of the bottom of the dish-shaped container 3 and the raised portion 6 is directly formed.

[Effect of the device]

 As described above, according to the present invention, in a dish-shaped container formed by a side portion and a bottom portion, a curved portion is interposed between the side portion and the bottom portion and between the side portions so that an acute angle portion does not exist. Since a raised part is provided on the central part of the bottom, microwaves for cooking are not concentrated in the corners and the food in the container heats up quickly because it heats from the center of the container. As a result, the reheating time is greatly shortened. Further, even if the pressure in the container is increased by heating, the protrusion of the ridge below the bottom prevents deformation of the container. Further, since the lid body that is inserted and fitted for sealing is provided with the protruding piece portion having a large number of small irregularities, there is an effect that it is easy to remove and remove.
