The present invention relates to a product suitable for business use.

食材を密封して保存することができ、電子レンジでの加熱調理にも使用できる容器が多く開発されている。このような容器には、電子レンジで食材を美味しく調理できるものや、食材の保存に適するように密閉性に優れているものが提案されている。その一例として、以下に示すようなものがある。   Many containers have been developed that can keep foods sealed and can be used for cooking in a microwave oven. As such containers, those that can be used to cook foods with a microwave oven and those that are excellent in hermeticity so as to be suitable for preservation of foods have been proposed. One example is as follows.

特開２００７−２８２９８７号公報JP 2007-282987 A 実用新案３０８８１６４号公報Utility Model No. 3088164

特許文献１には、蓋体に嵌合する蒸気を排出するキャップを具える容器が開示されている。この容器によれば、電子レンジで加熱調理するとき、容器内部の蒸気圧が急上昇しても、噴きこぼれが発生する前に適切な蒸気圧で蒸気を速やかに排出して、容器外周や電子レンジ内を汚さず、食材を美味しく、食材の栄養素を減らさず、効率良く、安全に調理ができる、蒸気圧の調節機能に優れた容器を提供できるとされている。
また、特許文献２には、蓋体と容器本体を密閉するパッキンを有し、蓋体に蒸気孔が形成され、蒸気孔に閉塞付勢機能を有するプッシュ栓方式の開閉弁機構が設けられた容器が開示されている。この容器によれば、蓋体の開閉操作が容易で且つ密閉機能に優れた食品保存用容器が提供できるとされている。 Patent Document 1 discloses a container including a cap that discharges steam fitted to a lid. According to this container, when cooking in a microwave oven, even if the vapor pressure inside the container suddenly rises, the steam is quickly discharged at an appropriate vapor pressure before the spill occurs, It is said that it can provide a container with excellent vapor pressure regulation function that can be cooked efficiently and safely without polluting the inside, without sacrificing the ingredients, without reducing the nutrients of the ingredients.
Further, Patent Document 2 is provided with a push plug type on-off valve mechanism having a packing that seals the lid and the container body, a vapor hole is formed in the lid, and the vapor hole has a closing biasing function. A container is disclosed. According to this container, it is said that a food storage container that can be easily opened and closed and has an excellent sealing function can be provided.

特許文献１のように、蒸気を排出するキャップと蓋体、そして蓋体と容器本体が嵌合するタイプの、食材の保存よりも電子レンジでの調理を主な目的とした容器の場合、その多くは使い捨て用に開発されたものであるため、容器本体や蓋体、キャップの耐久性は高くない。このため、これらの容器を繰返し洗浄して何度も使用すると、容器を洗浄することにより、また、そのときに嵌合部を着脱するといったことが積み重なり、容器本体や蓋体、キャップが変形し、嵌合部が徐々に緩んでしまうという問題がある。特に、自動洗浄機で高温洗浄した場合、容器本体等はより変形しやすい。当然、嵌合部が緩むと容器の密閉機能や蒸気排出機能を十分に果たすことができなくなる。
また、特許文献２のような、保存及び電子レンジでの調理という繰返し使用されることが想定されている容器では、繰返し使用されることによる容器本体等の変形や、蒸気排出部材が機能しなくなるという問題は生じないが、蒸気排出部材が複雑であるため、容易に分解ができず、細部まで洗浄することが困難であり、衛生的に保つことが難しいという問題がある。 In the case of a container whose main purpose is cooking in a microwave oven rather than storage of food, a cap and lid that discharge steam, and a lid and a container body are fitted as in Patent Document 1, Since many are developed for disposable use, the durability of the container body, lid, and cap is not high. For this reason, if these containers are repeatedly washed and used many times, the container will be washed and the fitting part will be removed and attached at that time, and the container body, lid and cap will be deformed. There is a problem that the fitting part gradually loosens. In particular, when high-temperature washing is performed with an automatic washing machine, the container body and the like are more easily deformed. Naturally, when the fitting portion is loosened, the container sealing function and the steam discharging function cannot be sufficiently achieved.
Further, in a container such as Patent Document 2 that is supposed to be repeatedly used for storage and cooking in a microwave oven, deformation of the container body and the like due to repeated use, and the steam discharge member do not function. However, since the vapor discharge member is complicated, it cannot be easily disassembled, it is difficult to clean the details, and it is difficult to keep it hygienic.

そこで、本発明は、前述した問題に鑑み、食品を密封して保存でき、電子レンジでの加熱調理のとき、蒸気圧を自動的に調節できる機能を具え、蒸気排出部材が単純な構造で、簡単に着脱でき、しかも、細部まで洗浄できることにより衛生的に保つことができる電子レンジ調理用容器を提供することをその目的とする。   Therefore, in view of the above-mentioned problems, the present invention can store food in a sealed state, has a function of automatically adjusting the vapor pressure when cooking in a microwave oven, and the vapor discharge member has a simple structure, It is an object of the present invention to provide a microwave cooking container that can be easily attached and detached and that can be kept hygienic by being able to wash the details.

本発明は、食材が収納される容器本体、雄ねじ部を具える取付部及びキャップからなる蒸気排出部材がねじ込まれる雌ねじ部を具える蓋体を有し、
前記キャップが、該キャップの中央部に、前記蓋体と接する面に向けて突出した凸部と、少なくとも１つの蒸気排出孔を具え、
前記蓋体が、前記凸部が嵌合する孔を有することを特徴とする電子レンジ調理用容器によって、前記課題を解決した。 The present invention includes a container body that contains foodstuffs, a mounting portion that has a male screw portion, and a lid that has a female screw portion into which a steam discharge member consisting of a cap is screwed.
The cap includes a convex portion projecting toward a surface in contact with the lid, and at least one vapor discharge hole at a central portion of the cap,
The said subject was solved by the container for microwave oven cooking characterized by the said cover body having the hole which the said convex part fits.

また、請求項２のように、凸部の蓋体と接する面が半球状であることが好ましく、請求項３のように、凸部の上部に取っ手が設けられているのがよい。   Moreover, it is preferable that the surface which contacts the cover body of a convex part is hemispherical like Claim 2, and it is good that the handle is provided in the upper part of the convex part like Claim 3.

また、請求項４のように、蓋体の凸部が嵌合する孔の周部が蓋体の外側に向け盛り上がっていることが好ましい。   Moreover, it is preferable that the peripheral part of the hole which the convex part of a cover body fits as the 4th aspect rises toward the outer side of the cover body.

また、請求項５のように、取付部が雄ねじ部に替え外歯を具え、蓋体が雌ねじ部に替え、外歯が嵌め込まれる切欠部と内歯を具え、外歯が切欠部に嵌め込まれ、内歯の下に回されることにより外歯と内歯が上下方向に重なり圧接することで蒸気排出部材が蓋体に固定される構成としてもよい。   Further, as in claim 5, the mounting portion is replaced with a male screw portion and external teeth are provided, the lid is replaced with a female screw portion, and a cutout portion and internal teeth are fitted into the external teeth, and the external teeth are fitted into the cutout portions. The steam discharge member may be fixed to the lid body by rotating under the inner teeth so that the outer teeth and the inner teeth overlap in pressure in the vertical direction.

また、請求項６のように、請求項５において、外歯と内歯の接する面が段階的に形成されていることが好適である。   Further, as in claim 6, in claim 5, it is preferable that the surface in contact with the external teeth and the internal teeth is formed stepwise.

また、請求項７のように、請求項５又は６において、外歯と内歯が楔形状となっていることが好ましい。   Further, as in claim 7, in claim 5 or 6, it is preferable that the outer teeth and the inner teeth have a wedge shape.

請求項１の発明によれば、蒸気排出部材が蓋体にねじ込まれ、キャップの中央部の蓋体と接する面に向けて突出した凸部が、蓋体の孔と嵌合するため、キャップと蓋体との密閉性が確保される。このようにして食材を密封して保存することができる。なお、蓋体と容器本体との密閉性は、蓋体と容器本体との間にパッキンを介挿したり、留め具を用いることで確保するとよい。本発明の特徴は、蓋体と蓋体にねじ込まれる蒸気排出部材にあるため、蓋体と容器本体との密閉性についての詳細な説明は省略する。   According to the first aspect of the present invention, the steam discharge member is screwed into the lid, and the convex portion protruding toward the surface in contact with the lid at the center of the cap fits into the hole of the lid, Sealing with the lid is ensured. In this way, the food can be sealed and stored. In addition, it is good to ensure the airtightness of a cover body and a container main body by inserting packing between a cover body and a container main body, or using a fastener. Since the feature of the present invention lies in the lid and the steam discharge member screwed into the lid, detailed description of the sealing property between the lid and the container body is omitted.

また、電子レンジで加熱調理するとき、容器の密閉性が確保されているため、収納される食材を素早く高温にすることができ、高い蒸気圧で調理することができる。このため、食材の栄養を食材内部に閉じ込め、美味しく調理することができる。さらに、加熱時に調味液が沸騰等して、容器内部の蒸気圧が急激に高まった場合には、発生した蒸気によりキャップの凸部が押上げられ、キャップと蓋体との間に隙間ができ、蒸気はその隙間を通り、キャップに設けられた蒸気排出孔から排出される。このため、容器内の蒸気圧が自動的に調節されることとなり、加熱調理時の噴きこぼれを防ぐことができる。このため、容器外周や電子レンジ内を汚すことなく安全に調理することができる。また、蒸気排出部材が取付部を介して蓋体にねじ込まれる構造であるから、容器を洗浄するとき、蒸気排出部材を簡単に取外すことができ、容器の細部まで容易に洗浄ができるため、容器を衛生的に保つことができる。   In addition, when cooking with a microwave oven, the hermeticity of the container is ensured, so that the stored food can be quickly heated to a high temperature and can be cooked at a high vapor pressure. For this reason, the nutrition of the food can be confined inside the food and can be cooked deliciously. Furthermore, if the seasoning liquid boils during heating and the vapor pressure inside the container suddenly increases, the raised portion of the cap is pushed up by the generated vapor, creating a gap between the cap and the lid. The steam passes through the gap and is discharged from a steam discharge hole provided in the cap. For this reason, the vapor pressure in the container is automatically adjusted, and spills during cooking can be prevented. For this reason, it can cook safely, without polluting the container outer periphery and the inside of a microwave oven. In addition, since the steam discharge member is screwed into the lid through the mounting portion, when cleaning the container, the steam discharge member can be easily removed and the details of the container can be easily cleaned. Can be kept hygienic.

また、請求項２のように、凸部の蓋体と接する面を半球状とすれば、凸部の中心と蓋体の孔の中心との位置が少しずれていても嵌合しやすく、密閉性を容易に確保でき、請求項３の構成によれば、キャップの着脱に便利である。   In addition, if the surface of the convex portion that contacts the lid is hemispherical as in claim 2, it is easy to fit even if the position of the center of the convex portion and the center of the hole of the lid is slightly shifted, Therefore, according to the third aspect of the present invention, it is convenient to attach and detach the cap.

また、請求項４のように、凸部が嵌合する蓋体の孔の周部が蓋体の外側に向け盛り上がっていれば、取付部がねじ込まれ、キャップが蓋体に押付けられた時に、キャップと蓋体との密着性を高めることができ、容器の密閉性を高めることができる。   Further, as in claim 4, if the peripheral portion of the hole of the lid body into which the convex portion is fitted rises toward the outside of the lid body, when the mounting portion is screwed and the cap is pressed against the lid body, Adhesion between the cap and the lid can be improved, and the sealing property of the container can be improved.

また、請求項５のように、取付部が雄ねじ部に替え外歯を具え、蓋体が雌ねじ部に替え、外歯が嵌め込まれる切欠部と内歯を具え、外歯が切欠部に嵌め込まれ、内歯の下に回されることにより外歯と内歯が上下方向に重なり圧接することで蒸気排出部材が蓋体に固定される構成とすれば、蒸気排出部材がねじ込まれる構成に比べ、より簡単な構造で、蒸気排出部材を簡便に着脱することができる。   Further, as in claim 5, the mounting portion is replaced with a male screw portion and external teeth are provided, the lid is replaced with a female screw portion, and a cutout portion and internal teeth are fitted into the external teeth, and the external teeth are fitted into the cutout portions. If the steam discharge member is fixed to the lid by rotating and pressing the inner teeth and the outer teeth and inner teeth overlap in the vertical direction, compared to the configuration in which the steam discharge member is screwed, The vapor discharge member can be easily attached and detached with a simpler structure.

また、請求項６のように、請求項５において、外歯と内歯の接する面が段階的に形成されていれば、取付部がキャップを押さえ付ける力を段階的に調節することができる。すなわち、容器の密閉性を調節し、電子レンジでの調理時の容器内部の蒸気圧を調節できることとなるため、調理する食材に適した蒸気圧を容易に実現することができる。さらに、請求項７のように、外歯と内歯を楔形状とすれば、取付部を楔効果で蓋体に締付けられるようなり、取付部が不用意に外れることを防ぐことができ、また、取付部を回すことによってキャップが蓋体に対し押え付けられるため、キャップと蓋体との密着性を容易に高めることができる。   Further, as in claim 6, if the surface in contact with the external teeth and the internal teeth is formed in stages, the force with which the mounting portion presses the cap can be adjusted in stages. That is, since the airtightness of the container can be adjusted and the vapor pressure inside the container during cooking in the microwave oven can be adjusted, a vapor pressure suitable for the food to be cooked can be easily realized. Furthermore, if the outer teeth and the inner teeth are formed in a wedge shape as in claim 7, the mounting portion can be fastened to the lid body by a wedge effect, and the mounting portion can be prevented from being inadvertently detached. Since the cap is pressed against the lid by turning the mounting portion, the adhesion between the cap and the lid can be easily increased.

以下、本発明の実施形態を図１〜７を参照して説明する。但し、本発明はこの実施形態に限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. However, the present invention is not limited to this embodiment.

図１は、本発明の容器１０の縦断面図である。容器１０は、容器本体１２、取付部３２及びキャップ３６からなる蒸気排出部材３０がねじ込まれる蓋体２０を有する。蒸気排出部材３０のキャップ３６は、少なくとも１つ、好ましくは複数の蒸気排出孔３６ａと凸部３６ｂを有する。蒸気排出部材３０は、蓋体２０に形成された雌ねじ部２４と、取付部３２に形成された雄ねじ部３４が螺合することにより、蓋体２０にねじで固定される。このとき、凸部３６ｂが蓋体の孔２２と嵌合し、容器の密閉性が確保される。このような単純な取付け構造であるため、簡単に着脱することができ、蒸気排出部材３０を外して細部まで洗浄できるため、容器を、常に、衛生的に保つことができる。なお、取付部３２につまみ３２ａを形成しておくと、着脱作業が容易になる。
なお、図示した実施形態では、取付部３２とキャップ３６は別体であるが、一体に成形してもよい。 FIG. 1 is a longitudinal sectional view of a container 10 of the present invention. The container 10 includes a lid body 20 into which a steam discharge member 30 including a container body 12, an attachment portion 32, and a cap 36 is screwed. The cap 36 of the steam discharge member 30 has at least one, preferably a plurality of steam discharge holes 36a and convex portions 36b. The steam discharge member 30 is fixed to the lid body 20 with a screw when the female screw portion 24 formed on the lid body 20 and the male screw portion 34 formed on the attachment portion 32 are screwed together. At this time, the convex part 36b fits into the hole 22 of the lid, and the hermeticity of the container is ensured. Since it is such a simple attachment structure, it can be easily attached and detached, and since the details can be cleaned by removing the vapor discharge member 30, the container can always be kept hygienic. In addition, if the knob 32a is formed in the attachment part 32, attachment / detachment work will become easy.
In the illustrated embodiment, the attachment portion 32 and the cap 36 are separate bodies, but may be formed integrally.

次に、容器１０に用いることができる素材について説明する。容器本体１２、蓋体２０、取付部３２には、耐熱性、耐油性を有し、耐久性の高い素材を用いることが好ましく、例えば、ポリミチルベンテン、ポリプロピレン、ガラス、陶器等を用いることができる。また、キャップ３６には、耐熱性があり、比重が高く、誘電損失係数の低い材質を用いることが好ましく、例えば、シリコーン樹脂を用いることができる。シリコーン樹脂は劣化しにくく、長期間使用できるため、特に好適である。   Next, materials that can be used for the container 10 will be described. For the container body 12, the lid 20, and the attachment portion 32, it is preferable to use a material having heat resistance and oil resistance and high durability. For example, polymityl bentene, polypropylene, glass, earthenware, or the like is used. it can. The cap 36 is preferably made of a material having heat resistance, a high specific gravity, and a low dielectric loss coefficient. For example, a silicone resin can be used. Silicone resins are particularly suitable because they are unlikely to deteriorate and can be used for a long time.

次に、図２は本発明の容器１０の平面図である。キャップ３６は円形形状が好ましいが、四角形等の形状であってもよい。また、凸部３６ｂの形状は、図４の（Ａ）に示すような、蓋体と接する面が立方体の形状、（Ｂ）に示すような、キャップの両面に突出している立方体の形状、（Ｃ）に示すような、キャップの両面に突出している球形状、（Ｄ）に示すような半面が立方体形状で強度を高めるためのリブ３６ｄを有し、他方の面が球形状、（Ｅ）に示すような、凸部３６ｂの上部に取っ手３６ｅを有する形状等、様々な形状を用いることができる。そして、蓋体と接する面３６ｃを半球状にすれば、凸部３６ｂの中心と蓋体の孔２２の中心との位置が少しずれていても嵌合しやすく、密閉性を容易に確保できる。また、（Ｅ）のような形状にすれば、蒸気排出部材３６の着脱を、取っ手３６ｅを掴むことで、簡便に行なうことができる。   Next, FIG. 2 is a plan view of the container 10 of the present invention. The cap 36 preferably has a circular shape, but may have a square shape or the like. Moreover, the shape of the convex part 36b is the shape of the cube which the surface which touches a cover body as shown to (A) of FIG. 4 protrudes on both surfaces of a cap as shown to (B), ( (C) a spherical shape protruding on both sides of the cap, a half surface as shown in (D) is a cubic shape, and has ribs 36d for increasing the strength, and the other surface is spherical, (E) Various shapes such as a shape having a handle 36e on the upper portion of the convex portion 36b can be used. If the surface 36c in contact with the lid is made hemispherical, it is easy to fit even if the position of the center of the convex portion 36b and the center of the hole 22 of the lid is slightly shifted, and the sealing performance can be easily secured. Moreover, if it is made into the shape like (E), attachment or detachment of the vapor | steam exhaust member 36 can be simply performed by grasping the handle 36e.

次に、図３を参照して、容器１０で食材を保存している状態、及び電子レンジで加熱調理している状態について説明する。   Next, with reference to FIG. 3, the state which preserve | saves the foodstuff with the container 10 and the state cooked with the microwave oven are demonstrated.

図３は、容器１０で食材を保存している状態、及び電子レンジで加熱調理している状態の蒸気排出部材３０を拡大した縦断面図である。蓋体２０の雌ねじ部２４と、取付部３２の雄ねじ部３４が螺合することにより、キャップ３６の凸部３６ｂと蓋体２０の孔２２が嵌合し、密閉性が確保されている。凸部３６ｂの重みで蓋体２０の孔２２を塞ぐ構造であるため、凸部３６ｂは中実で、また、比重が高い素材を用いることが好ましい。このように密閉性が確保されるため、食材の保存容器としても適しており、また、電子レンジで加熱調理したとき、蒸気漏れが発生せず、食材を素早く高温にでき、高い蒸気圧で調理できる。このため、食材の栄養を食材内部に閉じ込め、美味しく調理することができる。   FIG. 3 is an enlarged vertical cross-sectional view of the steam discharge member 30 in a state where food is stored in the container 10 and a state where cooking is performed in a microwave oven. When the female thread portion 24 of the lid 20 and the male thread portion 34 of the attachment portion 32 are screwed together, the convex portion 36b of the cap 36 and the hole 22 of the lid body 20 are fitted to ensure sealing. Since the structure is such that the hole 22 of the lid 20 is closed by the weight of the convex portion 36b, it is preferable to use a material having a solid and high specific gravity for the convex portion 36b. In this way, because it is sealed, it is also suitable as a storage container for foodstuffs, and when cooked in a microwave oven, steam leakage does not occur, the foodstuff can be quickly heated to high temperature, and cooked with high steam pressure it can. For this reason, the nutrition of the food can be confined inside the food and can be cooked deliciously.

図３（Ｂ）は、電子レンジで加熱調理しているとき、容器内の蒸気圧が上昇したときの蒸気排出部材３０を拡大した縦断面図である。矢印は蒸気の流れを表している。容器内の蒸気圧が上昇したとき、蒸気は凸部３６ｂを押上げ、キャップ３６と蓋体２０との隙間を通り、蒸気排出孔３６ａを通って容器外部に排出される。このため、容器内の蒸気圧が自動的に調節され、調味液等の液体が噴きこぼれることがない。すなわち、容器外周や電子レンジ内を汚さずに、かつ、安全に調理できる。なお、どの程度の蒸気圧で蒸気が排出されるかは、主に、凸部３６ｂの重さによって決まる。   FIG. 3B is an enlarged vertical cross-sectional view of the steam discharge member 30 when the steam pressure in the container rises when cooking with a microwave oven. Arrows indicate steam flow. When the vapor pressure in the container rises, the vapor pushes up the protrusion 36b, passes through the gap between the cap 36 and the lid 20, and is discharged outside the container through the vapor discharge hole 36a. For this reason, the vapor pressure in the container is automatically adjusted, and liquid such as seasoning liquid does not spill. That is, cooking can be performed safely without polluting the outer periphery of the container or the inside of the microwave oven. Note that the degree of vapor pressure at which the vapor is discharged is mainly determined by the weight of the convex portion 36b.

図７は、本発明の第二実施形態の容器の蓋体２０ａ、取付部３２、キャップ３６の解体時の立体斜視図である。取付部３２の外歯３２ｂが蓋体２０ａの切欠部２６に嵌合し、内歯２７の下に回されることにより、外歯３２ｂと内歯２７が上下方向に重なり圧接することによって蒸気排出部材３０が蓋体２０ａに取付けられる。このとき、取付部３２によってキャップ３６が押え付けられるため、キャップ３６と蓋体２０ａとの密着性が確保される。なお、取付部３２には、取付部３２を簡単に回すことができるようにつまみ３２ａが設けられている。   FIG. 7 is a three-dimensional perspective view of the container lid 20a, the attachment portion 32, and the cap 36 of the second embodiment of the present invention when disassembled. When the external teeth 32b of the mounting portion 32 are fitted into the notches 26 of the lid 20a and are rotated under the internal teeth 27, the external teeth 32b and the internal teeth 27 overlap in pressure in the vertical direction to discharge steam. The member 30 is attached to the lid 20a. At this time, since the cap 36 is pressed by the mounting portion 32, the adhesion between the cap 36 and the lid 20a is ensured. The attachment portion 32 is provided with a knob 32a so that the attachment portion 32 can be easily rotated.

また、図５に示すように、凸部３６ｂが嵌合する蓋体２０ａの孔２２の周部２５が蓋体の外側に向け盛り上がっていれば、キャップ３６と蓋体２０ａとが密着し易くなり、密閉性を高めることができる。   Further, as shown in FIG. 5, if the peripheral portion 25 of the hole 22 of the lid body 20a into which the convex portion 36b is fitted is raised toward the outside of the lid body, the cap 36 and the lid body 20a are easily in close contact with each other. , Can improve the sealing performance.

次に、図６は、本発明の第二実施形態の容器の蓋体２０ａの平面図である。図６に示すように、取付部３２の外歯３２ｂが、蓋体２０ａの切欠部２６に嵌合し、その後、内歯２７に向けて押し回され、蒸気排出部材３０が蓋体２０ａに取付けられる。図７に示すように、外歯３２ｂと内歯２７が楔形状に加工されていれば、楔効果を利用して取付部３２を蓋体２０ａに締付けることができるため、取付部３２が不用意に外れることを防ぐことができ、キャップ３６を蓋体２０ａに簡単に押さえ付けることができる。   Next, FIG. 6 is a plan view of the lid 20a of the container according to the second embodiment of the present invention. As shown in FIG. 6, the external teeth 32b of the attachment portion 32 are fitted into the notches 26 of the lid body 20a, and then pushed toward the internal teeth 27, so that the steam discharge member 30 is attached to the lid body 20a. It is done. As shown in FIG. 7, if the outer teeth 32b and the inner teeth 27 are processed into a wedge shape, the attachment portion 32 can be fastened to the lid 20a using the wedge effect. And the cap 36 can be easily pressed against the lid 20a.

なお、図７に示す構成では、電子レンジでの調理の際、どの程度の蒸気圧で蒸気が排出されるかは、主に、取付部３２の締付け具合によって決まる。そこで、蓋体２０ａの内歯２７と外歯３２ｂの接する面には、それぞれ段差２７ａ、３２ｃが設けられており、取付部３２を段階的に押し回すことができ、取付部３２がキャップ３６を押え付ける力を段階的に簡便に調節できる。すなわち、１段目まで締めたときと、２段目まで締めたときとでは、キャップ３６が蓋体に押さえ付けられる力が異なり、１段目よりも２段目まで締めているときの方が、その力が強いため、電子レンジで調理する時、蒸気が排出されるには高い蒸気圧が必要となるため、容器内部の蒸気圧を高く保つことができることとなる。このように段差２７ａ、３２ｃを少なくとも１つ設けることにより、調理する食材に応じた適切な蒸気圧を簡便に実現でき、食材を美味しく調理することができるようになる。なお、内歯２７にはストッパー２７ｂが設けられており、取付部３２の回し過ぎによる破損や怪我の防止が図られている。   In the configuration shown in FIG. 7, the steam pressure at which steam is discharged during cooking in the microwave oven is mainly determined by the degree of tightening of the attachment portion 32. Accordingly, steps 27a and 32c are respectively provided on the surface of the lid 20a where the inner teeth 27 and the outer teeth 32b are in contact with each other, so that the mounting portion 32 can be pushed around in stages, and the mounting portion 32 attaches the cap 36. The pressing force can be easily adjusted step by step. That is, when the cap is tightened up to the first step and when the cap is tightened up to the second step, the force with which the cap 36 is pressed against the lid body is different. Since the force is strong, when cooking in a microwave oven, a high steam pressure is required for the steam to be discharged, so the steam pressure inside the container can be kept high. Thus, by providing at least one step 27a, 32c, it is possible to easily realize an appropriate vapor pressure according to the food to be cooked, and to cook the food deliciously. The inner tooth 27 is provided with a stopper 27b to prevent damage and injury due to excessive rotation of the mounting portion 32.

以上、説明したように、本発明によれば、蒸気排出部材が蓋体にねじ込まれるという単純な取付け構造であるため、蒸気排出部材を簡便に着脱でき、蒸気排出部材を取外して細部まで洗浄できるため、容器を衛生的に保つことができる。また、蒸気排出部材が蓋体にねじ込まれることにより、キャップの中央部に突出した凸部と、蓋体の孔が嵌合するため、容器の密閉性が確保される。このため、食材の保存にも適しており、また、電子レンジで加熱調理したときの蒸気漏れを防ぎ、美味しく調理できる容器を提供することができる。さらに、キャップに少なくとも１つの蒸気排出孔が設けられているため、電子レンジで加熱調理したとき、容器内部の蒸気圧が高まった場合でも、蒸気を容器外部に速やかに自動的に排出し、容器内部の蒸気圧を調節することができる。このため、調理時に容器外周や電子レンジ内を汚さない、安全に調理できる容器を提供することができる。また、取付部に外歯を設け、蓋体に外歯が嵌め込まれる切欠部と、外歯を押さえる内歯を設けることにより、外歯を内歯の下に回すだけで蒸気排出部材を蓋体に取付けることができるようになるため、蒸気排出部材をねじ込む構成よりも簡便に蒸気排出部材を着脱することができる。さらに、外歯及び内歯を楔形状とすれば、取付部を蓋体に対し楔効果を利用して締付けることができ、取付部を回すことによってキャップを蓋体に簡単に押さえ付けることができる。また、外歯、内歯を段階的に形成することにより、取付部がキャップを押さえ付ける力を段階的に調節でき、電子レンジでの調理時の容器内部の蒸気圧を段階的に調節できることとなるため、調理する食材に応じた適切な蒸気圧を簡便に実現でき、食材を美味しく調理できる容器を提供することができる。   As described above, according to the present invention, since the vapor discharge member has a simple mounting structure in which the vapor discharge member is screwed into the lid, the vapor discharge member can be easily attached and detached, and the vapor discharge member can be removed to clean the details. Therefore, the container can be kept hygienic. Moreover, since the convex part which protruded in the center part of the cap and the hole of a cover body fit by screwing a vapor | steam discharge member in a cover body, the airtightness of a container is ensured. For this reason, it is suitable also for preservation | save of a foodstuff, can prevent the vapor | steam leakage when cooking with a microwave oven, and can provide the container which can be cooked deliciously. Furthermore, since at least one steam discharge hole is provided in the cap, even when the steam pressure inside the container is increased when cooking with a microwave oven, the steam is quickly and automatically discharged outside the container. The internal vapor pressure can be adjusted. For this reason, the container which can be cooked safely without polluting the container outer periphery and the inside of a microwave oven at the time of cooking can be provided. In addition, by providing external teeth on the mounting part, and providing notches into which the external teeth are fitted into the lid and internal teeth that hold down the external teeth, the vapor discharge member can be simply closed by turning the external teeth below the internal teeth. Therefore, the steam discharge member can be attached and detached more easily than the configuration in which the steam discharge member is screwed. Furthermore, if the outer teeth and the inner teeth are wedge-shaped, the mounting portion can be tightened to the lid using the wedge effect, and the cap can be easily pressed against the lid by turning the mounting portion. . Also, by forming the outer teeth and inner teeth in stages, the force with which the mounting part presses the cap can be adjusted in stages, and the vapor pressure inside the container during cooking in the microwave can be adjusted in stages. Therefore, an appropriate vapor pressure according to the food to be cooked can be easily realized, and a container that can cook the food deliciously can be provided.
