〔産業上の利用分野〕
本発明は、内容物の加熱を均一におこなわせるマイクロ
波の加熱用容器に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a microwave heating container that uniformly heats the contents.
〔従来の技術
および発明が解決しようとした課題）
電子レンジを用いて容器のまま加熱できる食品が昨今多
く出回ってぎている。[Prior art and problems to be solved by the invention] Recently, many foods that can be heated in a microwave oven have been on the market.
しかしながら、電子レンジで所定時間加熱しても、飲食
したとき加熱が不十分であったと感じることがある。こ
れは、電子レンジでの加熱が容器の角部や表層部分だけ
を加熱し、容器内部の全体を均一に加熱していないこと
から生じていた。殊に流動性の少ないものの場合には表
面付近は非常に温められているにもかかわらず中央部が
まだ冷たく、加熱後更に内容物を撹拌しなければならな
かった。これを詳しく調べると次のようなことが判明し
た。However, even if the food is heated in a microwave oven for a predetermined period of time, the user may feel that the food was not heated sufficiently when eating or drinking. This occurred because heating in a microwave oven heated only the corners and surface layer of the container and did not uniformly heat the entire inside of the container. Particularly in the case of materials with low fluidity, even though the surface area is extremely warmed, the center portion is still cold, and the contents must be further stirred after heating. A detailed investigation revealed the following.
■例えば内径が約６０ミリの円筒状容器の場合には、容
器の内側に沿ってリング状の加熱帯が内官物の上方と下
方に生成されるのみで、電子レンジの機種により容器の
中心軸上の何箇所かに加熱点が生じることがあるが、い
ずれも底の中央付近に加熱点は生じない。■For example, in the case of a cylindrical container with an inner diameter of approximately 60 mm, a ring-shaped heating zone is only generated along the inside of the container above and below the internal object, and depending on the model of microwave oven, a ring-shaped heating zone is generated at the center of the container. There may be heating spots at several locations on the shaft, but none near the center of the bottom.
■内径１００〜１３０ミリ、深さが２０〜３０ミリの丸
形偏平容器の場合には円筒状容器の場合と同様リング状
の加熱帯が上層と下層に生じ、底の中央付近に加熱点は
生じない。■For round and flat containers with an inner diameter of 100 to 130 mm and a depth of 20 to 30 mm, ring-shaped heating zones occur in the upper and lower layers, as in the case of cylindrical containers, and there is a heating point near the center of the bottom. Does not occur.
■楕円形偏平容器の場合には容器壁に沿ってリング状の
加熱帯が内容物の上方と下方に生成されるとともに容器
の長袖方向の何箇所かに加熱点が生じることがあるが、
底の中央付近に加熱点は生じない。■In the case of elliptical flat containers, ring-shaped heating zones are generated above and below the contents along the container wall, and heating points may occur at several locations along the long sleeve of the container.
There is no heating point near the center of the bottom.
■矩形容器の場合には、最初に底の四隅に加熱点が生じ
、それが上方及び底辺に沿って成長する一方上層におい
て容器の内面に沿って加熱帯が生じる。In the case of a rectangular container, heating points initially occur at the four corners of the bottom, which grow upwards and along the bottom edge, while a heating zone forms along the inner surface of the container in the upper layer.
■底部に波形の凹凸が形成しである容器の場合には、上
層と下層にリング状に加熱帯が生じる他波形の両端の凸
部に加熱点が発生するが、それ以外には生じない。(2) In the case of a container with a corrugated bottom, a ring-shaped heating zone will be formed on the upper and lower layers.Heating spots will occur at the convex portions at both ends of the corrugation, but will not occur anywhere else.
このように、いずれの場合も底の中央付近には加熱点は
発生せず、長時間電子レンジで加熱した場合でも上述し
たように内容物の上層や容器の底部の周縁付近などが加
熱されるのみで、中央部分の温度はこれら高温部からの
熱伝導によって昇温されはするが直接的に上昇するもの
ではなかった。In this way, in either case, no heating point occurs near the center of the bottom, and even when heated in a microwave oven for a long time, the upper layer of the contents and near the periphery of the bottom of the container are heated, as described above. The temperature in the central part was raised by heat conduction from these high-temperature parts, but it did not rise directly.
本発明では、上記問題点を解決するため、容器の少なく
とも底部中央に突起を設け、この突起にマイクロ波を集
中させて加熱点を生じさせることにより、容器の底部に
リング状に形成される加熱帯に加えて内容物を容器の底
部全体から加熱し、且つ内容物に対流を起こさせ容器内
で循環させることにより、均一に昇温されるようにした
のである。In order to solve the above-mentioned problems, the present invention provides a protrusion at least at the center of the bottom of the container, and by concentrating microwaves on the protrusion to generate a heating point, a ring-shaped heating point is formed at the bottom of the container. In addition to heating the contents from the entire bottom of the container, the contents were circulated within the container by causing convection to uniformly raise the temperature.
以下、本発明にかかる容器の一実施例について述べる。 An embodiment of the container according to the present invention will be described below.
まず第１図に第一の実施例を示す。この容器２は、ポリ
プロピレンからなり、直径が６０ミリ（上部開口径６７
ミリ）深さ１００ミリの円筒状の形状で、底部４の中央
に半径７ミリの球状の突起６が設けである。突起６は底
部４から下方に突出しており、すなわち容器２の内側か
らは球形の窪みとなっている。又、底部４の周囲には前
記突起６の長さより長い脚部８が形成しである。First, FIG. 1 shows a first embodiment. This container 2 is made of polypropylene and has a diameter of 60 mm (upper opening diameter 67 mm).
It has a cylindrical shape with a depth of 100 mm, and a spherical protrusion 6 with a radius of 7 mm is provided at the center of the bottom 4. The projection 6 projects downward from the bottom 4, ie, forms a spherical depression from the inside of the container 2. Further, a leg portion 8 longer than the length of the protrusion 6 is formed around the bottom portion 4.
かかる容器２に例えばスープなどを入れ電子レンジで加
熱すると、上記突起６内に加熱点が生じる。When such a container 2 is filled with soup or the like and heated in a microwave oven, a heating point is generated within the projection 6.
そして、この突起６がない状態において形成される底部
４の周縁及び内容物の上層の加熱帯と合わせて内容物、
つまりスープが底部４よりほぼ均一に加熱がなされる。The contents, together with the periphery of the bottom 4 and the heating zone on the upper layer of the contents, which are formed without this protrusion 6,
In other words, the soup is heated almost uniformly from the bottom 4.
更に、底部４が均一に加熱されるとともに突起６の加熱
点から対流が生じ、容器２の内部を内容物が循環するこ
とにより、より均一な加熱がなされる。尚、上記容器２
及び突起６の形状・数・材質等は上記述べたものに限る
ものではない。材質はポリプロピレンの他ポリエステル
など、又は積層したものでも、ガラス、セ°ラミック等
誘電体であればよい。更に、突起６の位置は必ずしも容
器２の中心軸上である必要はなく、通常加熱作用を充分
に受けない箇所であれば、リング状に形成される加熱帯
の内側のいずれの位置であってもよい。Furthermore, the bottom portion 4 is heated evenly and convection is generated from the heating point of the protrusion 6, and the contents circulate inside the container 2, thereby achieving more uniform heating. In addition, the above container 2
The shape, number, material, etc. of the protrusions 6 are not limited to those described above. The material may be polypropylene or polyester, or a laminated material, or a dielectric material such as glass or ceramic. Furthermore, the position of the protrusion 6 does not necessarily have to be on the central axis of the container 2, but may be located at any position inside the ring-shaped heating zone as long as it is not normally subjected to sufficient heating action. Good too.
次に容器および突起の形状・数を各種変化させて加熱し

以上述べたように容器の底部に所定の大きさ及び形状の
突起を設けることにより、底部中央に発熱点を形成でき
る。したがって、内容物を均一に加熱させることができ
る。As described above, by providing a protrusion of a predetermined size and shape on the bottom of the container, a heating point can be formed at the center of the bottom. Therefore, the contents can be heated uniformly.
これに対し、突起を有していないものには、底部中央に
発熱点が生じないので底部中央付近が加熱されないまま
冷たく残り、均一加熱ができなかった。以下かかる例の
実験例について具体的に述べる。On the other hand, in those without protrusions, no heating point was generated at the center of the bottom, so the area near the center of the bottom remained unheated and remained cold, making it impossible to heat uniformly. An experimental example of such an example will be described in detail below.

る。According to the present invention, since the protrusion is provided at least in the center of the bottom of the container, when heated with a microwave heating device, a heating point is generated at the center of the bottom, and in addition to the heating point at the periphery of the bottom that normally occurs, the entire bottom surface is heated. can be heated. Furthermore, since convection occurs from the heating point at the center of the bottom, heat transfer becomes more active, allowing the contents to be heated quickly and reliably and uniformly.
