 しかし、容器内の蒸気の圧力を利用した電子レンジ調理を目的とした場合、以下のような問題が生じる。
 (1)蓋体が上方移動する際、外部との経路となる隙間ができる構造の場合、容器内圧力がさらに高まると、蓋体は外れてしまい、容器内圧力を利用した調理はできない。
 (2)蒸気排出孔を設けた容器では、製造時に孔を開ける工程が必要となり、コストが増大する。
 (3)容器の嵌合力を高めるために、蓋体と容器本体の嵌合接触面積を単純に増やすと、嵌合させにくくなり、操作性が悪くなる。
However, when the purpose is microwave cooking using the pressure of steam in the container, the following problems occur.
(1) When the lid moves upward, in the case of a structure in which a gap serving as a path to the outside is formed, when the pressure in the container is further increased, the lid is removed, and cooking using the pressure in the container cannot be performed.
(2) In a container provided with a steam discharge hole, a process for opening the hole is required at the time of manufacture, and the cost increases.

 以下、本発明の第1実施形態について、図1、図2、図3及び図4を参照して説明する。 Hereinafter, a first embodiment of the present invention will be described with reference to FIG. 1, FIG. 2, FIG. 3, and FIG.
 図1は、第1実施形態における電子レンジ調理用容器10aの正面図であって、図中、符号20aは容器本体、30aは蓋体である。図2は図1のA部の拡大縦断面図、図3は容器本体20aの斜視図であり、図4は図3のB部の拡大図である。 FIG. 1 is a front view of a microwave cooking container 10a according to the first embodiment. In the figure, reference numeral 20a is a container body, and 30a is a lid. 2 is an enlarged vertical cross-sectional view of part A of FIG. 1, FIG. 3 is a perspective view of the container body 20a, and FIG. 4 is an enlarged view of part B of FIG.
 本発明の第1実施形態の電子レンジ調理用容器10aは、容器本体20a及び蓋体30aからなり、容器本体20aは、上部内側に、内向き波形突条60及び蒸気排出溝50を具え、蒸気排出溝50の部分で、波形突条60は途切れている。一方、蓋体30aは、下部に、環状折返し部80及び外向き波形突条70を具え、容器本体20aの内向き波形突条60と蓋体30aの外向き波形突条70が、上下で噛み合って係合することにより、容器本体20aと蓋体30aは外れないように嵌合させられる。 The microwave cooking container 10a according to the first embodiment of the present invention includes a container main body 20a and a lid 30a. The container main body 20a includes an inward corrugated ridge 60 and a steam discharge groove 50 on the inside of the upper part, and steam. The corrugated ridge 60 is interrupted at the portion of the discharge groove 50. On the other hand, the lid 30a includes an annular folded portion 80 and an outward corrugated ridge 70 in the lower portion, and the inward corrugated ridge 60 of the container body 20a and the outward corrugated ridge 70 of the lid 30a mesh with each other vertically. The container body 20a and the lid body 30a are fitted so as not to come off.
 この容器10aでは、容器本体20a上部に設けられた内向き波形突条60と、蓋体30aの環状折返し部80に設けられた外向き波形突条70が、上下で噛み合うように係合するので、蓋体30aと容器本体20aの接触嵌合面積が、従来より著しく増加するため、高い嵌合力を発揮することができる。 In this container 10a, the inward corrugated ridge 60 provided in the upper part of the container body 20a and the outward corrugated ridge 70 provided in the annular folded portion 80 of the lid 30a are engaged with each other so as to mesh with each other. Since the contact fitting area between the lid 30a and the container main body 20a is remarkably increased as compared with the conventional case, a high fitting force can be exhibited.
 容器本体20a、蓋体30aは、例えば、延伸ポリスチレン(OPS)、耐熱延伸ポリスチレン(耐熱OPS)、又はポリプロピレン(PP)等の耐熱性の良好なプラスチックシートを用い、圧空成形や真空成形等のサーモフォーミング法により成形される。 The container body 20a and the lid body 30a are made of, for example, a thermoplastic sheet having good heat resistance such as stretched polystyrene (OPS), heat-resistant stretched polystyrene (heat-resistant OPS), or polypropylene (PP). Molded by the forming method.
 容器本体20aは、円形をなし、底部の周囲から上方に開拡しつつ適宜の高さで容器本体の周壁28が立ち上がるように本体開口部が形成され、周壁28の上部内側に段部24、内向き波形突条60及び本体壁部26を形成することで、蓋体20aの下部の環状折返し部80が嵌合可能な本体嵌合部90が形成されている。 The container main body 20a has a circular shape, and a main body opening is formed so that the peripheral wall 28 of the container main body rises at an appropriate height while expanding upward from the periphery of the bottom portion. By forming the inward corrugated ridge 60 and the main body wall portion 26, a main body fitting portion 90 is formed into which the annular folded portion 80 at the lower portion of the lid 20a can be fitted.
 一方、蓋体30aは、円形の頂部より周壁36を下方に開拡しつつ、延伸させ、その周縁に、上向きに折り返し部80が形成され、その外部周壁に、容器本体20aの内向き波形突条60の下側に係合し得るように外側に張り出した外向き波形突条70が形成され、折返し部80は本体嵌合部90に圧嵌可能になっている。折返し部80の底部82が、容器本体20aの段部24に当て付けられることによって、容器本体20aと蓋体30aは密閉状態となる。 On the other hand, the lid 30a is extended while expanding the peripheral wall 36 downward from the circular top, and a folded portion 80 is formed upward at the periphery, and the inward corrugation of the container body 20a is formed on the outer peripheral wall. An outward corrugated ridge 70 projecting outward is formed so as to be able to engage with the lower side of the strip 60, and the folded portion 80 can be press-fitted to the main body fitting portion 90. When the bottom portion 82 of the folded portion 80 is applied to the stepped portion 24 of the container body 20a, the container body 20a and the lid body 30a are in a sealed state.
 次に、図2、図3及び図4が示すとおり、容器本体20a上部に環状に形成された容器本体20aの嵌合部90に、蒸気排出溝50が周方向に適宜の数で設けられている。この蒸気排出溝50は、或る深さをもって形成されているので、蓋体30aの折返し部80と係合したとき、外向き突条70と蒸気排出溝50は密着しておらず、その間に、隙間が形成される。なお、図2から分かるように、蓋体30aは、僅かに上方に移動可能になっている。 Next, as shown in FIGS. 2, 3, and 4, an appropriate number of steam discharge grooves 50 are provided in the circumferential direction in the fitting portion 90 of the container body 20 a formed in an annular shape on the container body 20 a. Yes. Since the steam discharge groove 50 is formed with a certain depth, the outward protrusion 70 and the steam discharge groove 50 are not in close contact with each other when engaged with the folded-back portion 80 of the lid 30a. A gap is formed. As can be seen from FIG. 2, the lid 30a is slightly movable upward.
 上記構造によれば、容器本体20aの内向き波形突条60と蓋体30aの外向き波形突条70が、上下で噛み合うように係合するため、容器本体20aと蓋体30aの嵌合接触面積は従来の嵌合接触面積よりも著しく増加しており、そのため、嵌合力が強化・増大されている。従って、調理工程に蒸し効果を必要とする調理メニューも、電子レンジを使用して作ることが可能となる。 According to the above structure, the inward corrugated ridge 60 of the container body 20a and the outward corrugated ridge 70 of the lid body 30a are engaged with each other so as to mesh with each other, so that the fitting contact between the container body 20a and the lid body 30a is achieved. The area is remarkably increased compared to the conventional mating contact area, and therefore the mating force is strengthened and increased. Therefore, a cooking menu that requires a steaming effect in the cooking process can also be created using the microwave oven.
 電子レンジで加熱調理する際、容器10a内で蒸気の圧力が上昇すると、まず、蓋体30aは上方に押し上げられる。その結果、蓋体30aの底部82と、容器が本体20aの段部24との間に隙間ができ、その結果、蒸気排出溝50が容器の内外を連通させて蒸気は外部に排出される。 When cooking with a microwave oven, when the steam pressure rises in the container 10a, the lid 30a is first pushed upward. As a result, a gap is formed between the bottom 82 of the lid 30a and the stepped portion 24 of the main body 20a. As a result, the steam discharge groove 50 communicates the inside and outside of the container and the steam is discharged to the outside.
 容器内の蒸気圧がさらに上昇した場合、容器本体20aの内向き波形突条60と蓋体30aの外向き波形突条70が、蓋体20aを開かせようとする力を分散させるため、容器10a内の蒸気の圧力を従来より高く維持することができる。
 容器10a内の圧力を高めに保つ時間は、蒸気排出溝50の幅や数を変えることで調整することができるから、メニューごとに、専用の電子レンジ調理用容器を製造することも可能である。
When the vapor pressure in the container further increases, the inward corrugated ridge 60 of the container body 20a and the outward corrugated ridge 70 of the lid body 30a disperse the force for opening the lid body 20a. The pressure of the steam in 10a can be maintained higher than before.
Since the time for keeping the pressure in the container 10a high can be adjusted by changing the width and number of the steam discharge grooves 50, a dedicated microwave cooking container can be manufactured for each menu. .
 次に、本発明の第2実施形態について、図5、図6及び図7を参照して説明する。なお、第1実施形態の電子レンジ調理用容器と同一の構成については同一の符号を使用し、説明は省略する。 Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, about the structure same as the container for microwave oven cooking of 1st Embodiment, the same code | symbol is used and description is abbreviate | omitted.
 図5は、第2実施形態の電子レンジ調理用容器10bの嵌合状態の正面図であって、図中、符号20bは容器本体、30bは蓋体である。図6は図5のC部の拡大縦断面図、図7は容器本体20bの斜視図である。 FIG. 5 is a front view of the fitting state of the microwave cooking container 10b of the second embodiment, in which the reference numeral 20b is a container body, and 30b is a lid. 6 is an enlarged vertical sectional view of a portion C in FIG. 5, and FIG. 7 is a perspective view of the container body 20b.
 容器本体20bには、上部内側に、2つ以上の環状凹溝62が形成され、蓋体の折返し部80’の環状外向き突条72がそこに嵌合可能になっている。図6から分かるように、蓋体30bは、僅かに上方に移動可能になっている。
 図6及び図7が示すとおり、第1実施形態同様、蒸気排出溝50が適宜の間隔で設けてあり、蓋体30bが蒸気圧で押し上げられたときは、ここから蒸気が排出される構造となっている。
Two or more annular grooves 62 are formed on the inner side of the container body 20b, and an annular outward protrusion 72 of the folded portion 80 'of the lid can be fitted therein. As can be seen from FIG. 6, the lid 30b is slightly movable upward.
6 and 7, as in the first embodiment, the steam discharge grooves 50 are provided at appropriate intervals, and when the lid 30b is pushed up by the steam pressure, the steam is discharged from here. It has become.
 上記構造により、容器10bの蓋体30bと容器本体20bの嵌合接触面積は従来の2倍以上に増大させられるため、嵌合力も2倍以上に強化されることになる。その結果、蒸気を一部は排出しつつ、内部の高めの蒸気圧を維持して、蒸し効果を発揮する調理が可能となる。 With the above structure, the fitting contact area between the lid 30b of the container 10b and the container main body 20b is increased more than twice that of the conventional case, so the fitting force is also increased more than twice. As a result, cooking that exhibits a steaming effect while maintaining a high internal vapor pressure while partially discharging the steam becomes possible.
 次に、本発明の第3実施形態について、図8を参照して説明する。なお、第1実施形態の電子レンジ調理用容器と同一の構成については同一の符号を使用し、説明は省略する。 Next, a third embodiment of the present invention will be described with reference to FIG. In addition, about the structure same as the container for microwave oven cooking of 1st Embodiment, the same code | symbol is used and description is abbreviate | omitted.
 容器内の蒸気圧が上昇すると、蓋体30aを押上げようとする力がはたらく。第1実施形態の内向き波形突条60と外向き波形突条70により、蓋体30aを押上げる力を分散させることができるが、内向き波形突条60と外向き波形突条70の形状がほぼ台形のため、波形突条の水平部分にかかる力については、蓋体30aを押し上げる力が、蓋体30aの外向き波形突条70から、直接、容器本体の内向き波形突条60の外向き波形突条7
0を乗り越えるようにかかることになる(図8(b)左図矢印参照)。従って、蒸気が大量に発生した場合は、波形突条の水平部分にかかる力が非常に大きくなる。
 そこで、本実施形態では、図8(a)に示すように、容器本体20cの内向き波形突条60cと蓋体30cの外向き波形突条70cの形状を、三角波の頂点を丸めた形としている。このようにすることで、内向き波形突条60cに外向き波形突条70cのどの部分から押上げ力がかかっても、力が斜め方向に軽減されるため(図8(b)右図矢印参照)、蓋体30cにかかる押上げ力を軽減することができる。従って、より確実に蓋体30cが外れるのを防止できる。なお、力学の法則により、図8(b)右図に、想像線と実線の対比で示すように、斜め方向の分力は、垂直方向に発生する力より小さい。
 内向き波形突条60cと外向き波形突条70cの数は、調理メニュー等に応じて適宜自由に決めることができるが、図8(c)の角度θが60°より大きいと、三角形状の部分が多くなり過ぎて、製造工程での誤差の管理が難しくなるばかりでなく、蓋体と容器本体の噛み合わせが難しくなり、一方、角度θが30°より小さいと、傾斜が緩やか過ぎて、内向き波形突条60cと外向き波形突条70cの嵌合力の増強効果が見られなくなるため、θは、30°~60°にするのが好適である。
When the vapor pressure in the container rises, a force that pushes up the lid 30a works. Although the force which pushes up the cover body 30a can be disperse | distributed by the inward corrugated protrusion 60 and the outward corrugated protrusion 70 of 1st Embodiment, the shape of the inward corrugated protrusion 60 and the outward corrugated protrusion 70 is possible. Because of the substantially trapezoidal shape, the force applied to the horizontal portion of the corrugated ridge is such that the force pushing up the lid 30a is directly applied to the inward corrugated ridge 60 of the container body directly from the outward corrugated ridge 70 of the lid 30a. Outward corrugated ridge 7
It will take over 0 (see the arrow on the left in FIG. 8B). Therefore, when a large amount of steam is generated, the force applied to the horizontal portion of the corrugated ridge becomes very large.
Therefore, in the present embodiment, as shown in FIG. 8A, the shape of the inward corrugated ridge 60c of the container body 20c and the outward corrugated ridge 70c of the lid body 30c are formed by rounding the apex of the triangular wave. Yes. By doing so, the force is reduced in an oblique direction no matter which part of the outward corrugated ridge 70c is applied to the inward corrugated ridge 60c (FIG. 8 (b) right arrow) See), and the pushing force applied to the lid 30c can be reduced. Therefore, it is possible to prevent the lid body 30c from coming off more reliably. Note that, due to the laws of mechanics, the diagonal component force is smaller than the force generated in the vertical direction, as shown in the right diagram of FIG.
The number of the inward corrugated ridges 60c and the outward corrugated ridges 70c can be determined as appropriate according to the cooking menu or the like, but if the angle θ in FIG. Too many parts, it becomes difficult to manage errors in the manufacturing process, it is difficult to mesh the lid and the container body, while if the angle θ is less than 30 °, the inclination is too gentle, Since the effect of enhancing the fitting force between the inward corrugated ridge 60c and the outward corrugated ridge 70c is not seen, θ is preferably set to 30 ° to 60 °.
 また、嵌合時に、相手の三角形の頂点を受け入れる側に位置する、内向き波型突条60cと外向き波型突条70cの三角形の頂点(図8(c)において、64cと74c’)を丸みが大きい形状にし、受け入れられる側に位置する内向き波型突条60cと外向き波型突条70cの三角形の頂点(図8(c)において、64c’と74c)を、それぞれ、端部64cと74c’より若干丸みが小さい形状にしている。嵌合する三角形の頂点の両方を丸みが小さい尖った形状にすると、容器本体と蓋体の製造工程において高い精度が要求されるが、このように、受け入れ側の三角形の頂点をより丸くすることで、蓋体と容器本体の製造誤差を吸収し、異なる型で製造した蓋体と容器本体であっても、組合せて使用することができるメリットがある。 Further, at the time of fitting, the triangular vertices of the inward corrugated ridge 60c and the outward corrugated ridge 70c (64c and 74c 'in FIG. 8C) are located on the side receiving the vertex of the counterpart triangle. And the triangular vertices (64c ′ and 74c in FIG. 8 (c)) of the inward corrugated ridges 60c and the outward corrugated ridges 70c located on the accepting side are respectively arranged at the ends. The portions 64c and 74c ′ are slightly rounded. If both the apexes of the triangles to be fitted have a sharp shape with a small roundness, high accuracy is required in the manufacturing process of the container body and the lid, but in this way, the apexes of the triangle on the receiving side should be rounded. Thus, manufacturing errors between the lid and the container main body are absorbed, and even if the lid and the container main body are manufactured in different types, there is an advantage that they can be used in combination.
 最後に、図9を参照して、本発明の第4実施形態について、第1実施形態と異なる部分を説明する。なお、第1実施形態の電子レンジ調理用容器と同一の構成については同一の符号を使用し、説明は省略する。 Finally, with reference to FIG. 9, a different part from 1st Embodiment is demonstrated about 4th Embodiment of this invention. In addition, about the structure same as the container for microwave oven cooking of 1st Embodiment, the same code | symbol is used and description is abbreviate | omitted.
 図9に示すように、本実施形態では、容器本体20dの上部内側と蓋体30d下部の折返し部に、それぞれ蒸気排出孔66と76を設けている。
 加熱調理終了直後の容器10dは、熱膨張により、容器本体20dの方が側面方向に膨張しているので、蓋体30dとの嵌合力が弱くなっている。従って、容器本体20dに対して、蓋体30dを回すことができる場合がある。
 そこで、容器本体20dに対して、蓋体30dを回し、容器本体20dの蒸気排出孔66と蓋体30dの蒸気排出孔76の位置を合わせて整列させれば、そこから蒸気が抜けるため、その後、蓋体30dを開ける際には、容器本体20d内の蒸気の量は少なくなっている。従って、加熱調理終了後に熱くなった大量の蒸気に手指が触れるのを未然に防ぐことができる。なお、この場合、最小限で、蓋体の波形の丁度1ピッチの回転移動で、蒸気排出孔が整列するようにしておくのが好適である。
 加熱調理中に、容器本体20dの内向き波形突条60と蓋体30dの外向き波形突条70が、上下で噛み合って係合している状態では、各蒸気排出孔は重ならないようにしておけば、加熱調理時に各蒸気排出孔から蒸気や煮汁等が漏れ出すことはない。
 なお、蒸気排出孔の数は、容器本体と蓋体1つずつに限定されず、必要に応じて複数設けてもよい。
As shown in FIG. 9, in this embodiment, steam discharge holes 66 and 76 are provided in the upper inner side of the container main body 20d and the folded portion at the lower part of the lid 30d, respectively.
The container 10d immediately after the end of heating cooking has a weaker fitting force with the lid 30d because the container body 20d is expanded in the lateral direction due to thermal expansion. Therefore, the lid 30d may be able to be rotated with respect to the container body 20d.
Therefore, if the lid 30d is rotated with respect to the container body 20d and the vapor discharge holes 66 of the container body 20d and the vapor discharge holes 76 of the lid body 30d are aligned and aligned, When the lid 30d is opened, the amount of steam in the container body 20d is reduced. Therefore, it is possible to prevent the fingers from touching a large amount of steam that has become hot after the end of cooking. In this case, it is preferable that the vapor discharge holes are aligned at a minimum by a rotational movement of exactly 1 pitch of the waveform of the lid.
During cooking, in a state where the inward corrugated ridge 60 of the container body 20d and the outward corrugated ridge 70 of the lid body 30d are engaged with each other in the vertical direction, the steam discharge holes should not overlap. If this is the case, steam, broth and the like will not leak from each steam discharge hole during cooking.
In addition, the number of vapor | steam discharge holes is not limited to a container main body and one lid body, You may provide two or more as needed.
 なお、図示はしないが、前記蒸気排出孔を具える実施形態は、波型突条が三角波の頂点を丸めた形状のものである第3実施形態の容器でも、当然実施可能である。
 また、前記蒸気排出孔を具える実施形態は、図5~7の第2実施形態の容器でも実施可能であり、この場合の方が、蓋体を回転させ易い。但し、この場合は、1ピッチではなく、角度が単位となり、例えば、蓋体を約30°回転させれば、蒸気排出孔が整列するようにしておくとよい。
Although not shown in the drawings, the embodiment having the steam discharge hole can naturally be implemented even in the container according to the third embodiment in which the wave-shaped ridge is formed by rounding the apex of the triangular wave.
Further, the embodiment including the vapor discharge hole can be implemented also in the container of the second embodiment shown in FIGS. 5 to 7, and in this case, the lid can be easily rotated. However, in this case, instead of one pitch, the angle is a unit. For example, if the lid is rotated about 30 °, the vapor discharge holes may be aligned.
 本発明によれば、電子レンジを使用して作る、蒸し効果を必要とする調理メニューを、比較的安価に提供すること可能となる。また、蓋体と容器本体の2点のみからなる構造であるため、製造コストが増大することはない。 According to the present invention, it is possible to provide a cooking menu that uses a microwave oven and requires a steaming effect at a relatively low cost. Moreover, since it is a structure which consists only of two points, a cover body and a container main body, a manufacturing cost does not increase.
