げたりできる。2. Description of the Related Art Conventionally, well-known pressure vessels include those made of metal such as aluminum. In the pressure vessel, a pressure regulating valve operates to maintain the internal pressure at about 2 atmospheres, and the boiling point of the water in the pressure vessel is raised to about 120°C. This results in
Heating is significantly accelerated, and simmering that normally takes 1 to 2 hours can be completed in about 30 minutes, and small fish can be made soft down to the bone.

を始めている。Products have already been proposed in which convenient pressure vessels are made of synthetic resin and can be used in microwave ovens.For example, in the United States, Nordaik Ware sells products under the trademark ``Tender Kutskar.'' ing. Additionally, in Japan, Asahi Light Metal Industry■ has begun selling it under the trademark ``Range Kisei Nabe.''

ある。The operating pressure of these pressure containers for microwave ovens is around 2 atm for gas pressure containers, whereas the operating pressure for the "Tender Kutsker" is about 1.7 atm and the operating pressure for the "Microwave Vitality Pot" is about 1.4 atm. It is low. For this reason, the ``Microwave Vitality Pot'' is used only for cooking rice, and the ``Tender Tsuka'' is mainly used for cooking meat.

こり易く高い破壊強度を達成することが困難であった。Problems to be Solved by the Invention However, at the above operating pressure, it is difficult to cook popular dishes made in a pressure vessel, such as brown rice, beans, and small fish, until they are soft. The reason for this is that the pressure-resistant strength of conventional pressure vessels for microwave ovens could not be achieved. All of these conventional pressure vessels are made by compression molding of unsaturated polyester, which is a thermosetting resin, reinforced with glass fibers, but because the curing reaction takes place in the mold, they are not thick-walled. It was difficult to achieve high fracture strength because the hardening inside and on the surface tended to change.

の不飽和ポリエステルは不透明である為、圧力容器内部
の状態が確認出来ず使い勝手が良くなかった。In addition, in these pressure vessels, once cooking is completed and the food is taken out to the table, it quickly cools down, and if you want to keep it delicious and warm, you have to transfer it to a heat insulating jar or the like, which is troublesome. Furthermore, since the glass fiber-containing unsaturated polyester mentioned above is opaque, it is not possible to check the condition inside the pressure vessel, making it difficult to use.

ことにある。The present invention is intended to solve the above-mentioned problems, and its first purpose is to realize a pressure vessel made of synthetic resin that is safe and has excellent heat insulation properties and has high breaking strength. To provide a pressure vessel whose internal state can be checked from the outside.

レンスルファイドなどが使用できる。The figure is a sectional view of a pressure vessel in one embodiment of the present invention. The pressure vessel 1 has a structure in which a container body 2 and a lid 3 that seals the container body 2 are closed by sandwiching a gasket 4 at the contact portion thereof. A pressure regulating valve 5 that maintains the internal pressure of the pressure vessel 1 at a constant pressure is provided on the lid body 3. Furthermore,
The container main body 2 is formed from a two-layered container outer resin layer 6 and container inner resin layer 7, and the lid 3 is formed from a lid outer resin layer 8 and a lid inner resin layer N9. An object to be heated 10 such as food is housed inside the pressure vessel 1 . The container body 2 and the lid 3 are made of highly heat-resistant thermoplastic resin. The molding method used is blow molding or injection molding and welding. As such a synthetic resin, various plastics having a high heat resistance temperature can be used, such as polymethylpentene, glass fiber reinforced polyethylene terecrate, polysulfone, and polyphenylene sulfide.

ることもできる。The container main body 2 and the lid 3 formed in a two-layer structure are constructed by having different material properties of the container outer resin layer 6, the container inner resin layer 7, and the lid outer resin layer 8 and the lid inner resin layer 9. You can also do it. That is, for the inner surface, materials are selected with emphasis on steam resistance, stain resistance, etc., and for the outer surface, materials are selected with emphasis on impact resistance, strength, colorability, etc. It is also possible to construct a two-layer structure with a hollow space between the eyebrows.
上記構成において、圧力容器の使い方としては従来と同
様であるが、本発明の一実施例としての圧力容器には次
の効果がある。In the above configuration, the pressure vessel is used in the same way as conventional pressure vessels, but the pressure vessel according to the embodiment of the present invention has the following effects.

ため調理物が冷め難い。The double structure of the container body and lid improves the pressure resistance of the pressure container. Also, by making the glabella hollow in this double structure, heat resistance is imparted and heat radiation loss is reduced, so heating time can be shortened. Furthermore, even if the container is taken out of the microwave and placed on the dining table, the food will not cool down easily due to its good insulation properties.
そしてまた容器本体と蓋体を透明樹脂の二重構造でその
層間を中空にしたので、保温性が良く、圧力容器の中の
状態をも見ることができ極めて便利である。Furthermore, since the container body and lid are made of a double layer structure of transparent resin with a hollow space between the layers, heat retention is good and the condition inside the pressure container can be seen, which is extremely convenient.
なお、実施例では二重構造の眉間を中空にした場合にっ
てい説明したが、中空ではなく２層、３層と積層して構
成してもよいし、層と層の間に弾性体を挟む構造にして
も良い。In addition, in the example, the case where the glabella of the double structure is hollow is explained, but instead of being hollow, it may be constructed by laminating two or three layers, or an elastic body may be placed between the layers. A sandwiching structure may also be used.

温性が良く中が見えて使い勝手が良くなる。Effects of the Invention As is clear from the above description, according to the present invention, since at least one of the container body and the lid has a multilayer structure, the pressure resistance as a pressure container can be improved, and the inner surface having different functions can be improved. For the side and outer surfaces, materials that meet the required characteristics can be used effectively. Further, by forming the hollow structure, the heat insulation properties can be improved, and the heat retention properties can be improved. Furthermore, the surface temperature of the container is low, eliminating any concerns about burns. Furthermore, if the pressure vessel is made of a multi-layered structure made of transparent resin, it will retain heat well even on a dining table, and the inside will be visible, making it easier to use.
