A cooking container according to the present invention is a cooking container that heats ingredients by irradiating microwaves, and is housed in an outer dish part containing a silicone polymer and silica or a fluororesin, and the outer dish part. Silica or fluororesin, and an inner dish portion including a heating element material that generates heat by microwaves, a non-exothermic outer lid that covers the outer dish portion, silicone polymer and silica, or fluororesin, and microwave A plurality of protrusions each having a recessed shape at the center on the inner bottom surface of the inner dish portion at positions separated from the inner side surface. The inner bottom surface of the inner lid portion is higher than the periphery, the inner upper surface of the inner lid portion is provided with irregularities, and the convex portion has a hemispherical shape .

According to the cooking container which concerns on this invention, while it is durable and lightweight, foodstuffs, such as a fish and meat, can be cooked when an inner side dish part heat | fever-generates, and food is heated richly. Moreover, although an inner side dish part rises to high temperature, since an outer side dish part is non-exothermic, a user's burn can be prevented. According to the present invention, since the outer lid portion and the inner lid portion cover each of the outer dish portion and the inner dish portion, the food can be heated while preventing evaporation of moisture, and cooked in a steamed form. In addition, the cooking time can be shortened by the radiation of the inner lid, and the food can be cooked richly because it can be heated evenly. In addition, since the fat content falls by placing the ingredients across multiple protrusions, the adhesion between the ingredients and the fat contents can be reduced, and the intake of excess fat contained in the ingredients can also be prevented. Can do. According to the present invention, the surface area is increased by the unevenness and the radiation efficiency is increased, so that the cooking time can be shortened.

  The cooking container according to the present invention is characterized in that the heating element material contains iron oxide and carbon.

  A cooking container according to the present invention will be described. 1 to 3 are a top view, a side view, and a bottom view, respectively, showing a cooking container according to the present invention. 4 and 5 are a top view and a side sectional view in the long side direction showing the dish portion 1 of the cooking container according to the present invention, and FIGS. 6 and 7 are bottom views showing the lid portion 2 of the cooking container according to the present invention. It is a figure and a side sectional view of a long side direction.

  The cooking container which concerns on this invention consists of the cover part 2 which covers the plate part 1 and the dish part 1 which were opened by which a foodstuff is mounted. The dish part 1 is further integrally molded with the inner dish part 11 and the inner dish part 11 made of black exothermic rubber mixed with silicone polymer, silica, iron oxide and carbon, and accommodates the inner dish part 11. And an outer dish portion 12 made of non-exothermic rubber mixed with silicone polymer and silica. Silicone polymer and silica do not generate heat because they do not absorb microwaves, but iron oxide and carbon are heat generating materials that generate heat by absorbing microwaves. For example, iron oxide is triiron tetroxide and carbon is carbon black.

  The exothermic rubber generates heat by microwave irradiation and rises to a high temperature in a short time, so that ingredients such as fish and meat can be cooked and the ingredients can be cooked with a rich flavor.

  The lid portion 2 is also composed of an inner lid portion 21 made of black exothermic rubber mixed with silicone polymer, silica, iron oxide and carbon, and an inner lid portion made of non-exothermic rubber mixed with silicone polymer and silica. And an outer lid portion 22 that accommodates 21. The inner lid portion 21 and the outer lid portion 22 are shaped to cover the inner dish portion 11 and the outer dish portion 12, respectively.

  Exothermic rubbers and non-exothermic rubbers have heat resistance that does not deteriorate their properties at high temperatures from about 200 ° C to about 250 ° C. Therefore, the cooking container which concerns on this invention has the durability which maintains a property even if it heats from about 200 degreeC to about 250 degreeC.

  The inner dish part 11 is composed of a bottom part 11a and a side part 11b having a thickness of about 2 mm and has an open shape. The bottom portion 11a is a substantially rectangular shape with rounded corners having a short side of about 12 cm and a long side of about 21 cm, and is provided with protrusions 11c, 11c,. Further, the protrusions 11c, 11c,... Have elongated shapes that are substantially parallel to each other in the short side direction of the substantially rectangular bottom surface, so that the foodstuff is placed across the plurality of protrusions 11c, 11c,. Nine are provided at approximately equal intervals of about 16 mm. In addition, the protrusions 11c, 11c,... And the side part 11b are separated from each other so that fat can be easily collected around the bottom part 11a.

  By placing the food material on the protrusions 11c, 11c,..., The fat content falls to the bottom 11a, so that the adhesion between the food material and the fat content can be reduced, and the intake of excess fat content contained in the food material Can also prevent. Further, since the fat content of the food falls directly below, it tends to accumulate near the center of the bottom 11a. Therefore, the vicinity of the center of the bottom portion 11a is configured to be about 3 mm higher than the periphery so that the fat component flows to the periphery.

  The side portion 11b of the inner dish portion 11 has a height of about 3 cm in the vertical direction along the outer periphery of the bottom portion 11a. A step 11d is provided which includes a flat wall of about 2 mm in the horizontal direction and a side wall extending about 2 mm in the vertical direction from the flat portion along the outer periphery which is the upper portion of the side portion 11b. The outer peripheral portion of the lid portion 2 is placed on the flat wall, and the position of the lid portion 2 is fixed by the side wall. Since the sealed space is formed in the cooking container by the lid portion 2, the food can be heated while preventing evaporation of moisture and cooked in a steamed shape. Further, the intrusion of microwaves can be prevented by contacting the inner dish part 11 which is a heating element of the dish part 1 and the inner lid part 21 which is a heating element of the lid part 2, so that the microwave is not directly irradiated to the foodstuff. I'm sorry.

  Since the exothermic rubber that has generated heat is heated not only by direct heating but also by radiation, in addition to the bottom portion 11a of the inner dish portion 11 that is in contact with the food and the projections 11c, 11c, ..., the side portion 11b that is not in contact with the food The food material is also heated from the inner lid portion 21. Therefore, the cooking time can be shortened and the food can be cooked with rich flavor because it can be heated evenly.

  Therefore, the inner lid portion 21 is provided with a plurality of hemispherical convex portions 21a, 21a,... To increase the surface area and increase the radiation efficiency.

  Four grooves are provided on the side surface of the step 11 d of the inner dish portion 11. This is for facilitating fixing to the mold when the inner dish portion 11 is molded and for facilitating removal from the mold.

  The side 12b of the outer plate 12 is about 3 mm thicker than the bottom 12a, but the upper step 11d is thicker about 5 mm. This is to prevent the plate part 1 from being deformed due to the weight of the cover part 2 when the cover part 2 is placed or the use for a long period of time. Further, the side portion 12b of the outer dish portion 12 is provided with wavy irregularities along the circumference.

  In order to reinforce the protrusions 11c, 11c,... Of the inner dish part 11 to such an extent that they do not deform due to the weight of the foodstuff, the bottom part 12a of the outer dish part 12 corresponds to the shape of the protrusions 11c, 11c,. A protrusion 12c is provided. Dish part handles 12d and 12d are provided on both side surfaces of the outer dish part 12 in the long side direction.

  As described above, the outer dish portion 12 itself does not generate heat, but the heat of the inner dish portion 11 and the food may be transferred to the high temperature. For this reason, the tray handles 12d and 12d are provided with holes so as to return to room temperature in a short time after the microwave heating is completed, thereby increasing the surface area.

  When the cooking container is heated, steam is generated from the ingredients placed in the cooking container and becomes high pressure. Therefore, a part of the steam must be discharged to the outside of the cooking container. On the other hand, it is necessary to keep the steam in the container in order to make the food material into the aforementioned steamed and grilled form. Therefore, six steam holes 23, 23,... Having a diameter of about 2 mm that penetrate the inner lid portion 21 and the outer lid portion 22 are provided. The six steam holes 23, 23,... Are about 4 cm away from the outer periphery of the lid handle 22 a so that there is no burn when holding the lid handle 22 a provided at the center of the outer lid 22 to hold the cooking container. It is provided at the position.

  In order to stabilize the position of the foodstuff placed near the center, the projections 11c, 11c,... May be arcuate in which the vicinity of the center is recessed in the vertical direction compared to the vicinity of both ends. In addition, the protrusions 11c, 11c,... May have any shape as long as the food can be placed thereon, and may have a shape extending in the long side direction, a circular shape, or a polygonal shape. Here, the gap between the plurality of protrusions 11c, 11c,... Is preferably 1 cm or more so that the gap between the protrusions 11c, 11c,.

  The hemispherical convex portions 21 a, 21 a,... Are not limited to the inner lid portion 21 and may be provided on the side portion 11 b of the inner dish portion 11. In addition, the shape of the convex portions 21a, 21a,... Is not limited to a hemispherical shape, and may be a polygonal shape or a corrugated shape.

  The cooking container may be completely sealed without providing the steam hole 23. Further, the number and size of the steam holes 23 are also arbitrary and may be provided in the dish portion 1.
