Description

本発明は、加熱調理容器の煮こぼれ防止に関する分野に属する。 The present invention belongs to the field relating to prevention of spilling of cooking containers.

蓋付きの鍋で煮炊きするときの煮こぼれや吹きこぼれを防止する技術は種々提案されている。例えば、蓋に孔を開けてその開度で吹きこぼれを防止する技術は、実用新案登録第３１２４６１２号公報（特許文献１）や特開２０１０−３５９７６号公報（特許文献２）などが挙げられるが、構造が複雑で使用後の衛生的な処理に多くの手間を要する。また、鍋本体１に対して蓋５を移動自在にして蒸気吹出凹部９から蒸気を吹き出させて煮こぼれを防止するものとして実開昭６２−１９２３３５号公報（特許文献３）が提案され、さらに、鍋の上縁を蓋の外周縁より高くして内側に曲げ、蓋の外周縁を鍋の内周に嵌め込むものとして、煮汁が鍋の外部にこぼれない構造として煮こぼれ防止を図る技術が、実用新案登録第３００８０２２号公報（特許文献４）に提案されているが、何れも鍋の上縁の内部に蓋を収めるものであるため、煮炊き時の衛生面に問題がある。 Various techniques have been proposed for preventing spills and spills when cooking in a pan with a lid. For example, as a technique for making a hole in the lid and preventing spillage at the opening degree, utility model registration No. 3124612 (Patent Document 1), Japanese Patent Application Laid-Open No. 2010-35976 (Patent Document 2), and the like can be mentioned. The structure is complex and requires a lot of labor for hygienic processing after use. Japanese Utility Model Laid-Open No. 62-192335 (Patent Document 3) is proposed to prevent the spilling by making the lid 5 movable with respect to the pan body 1 to blow the steam from the steam blowing recess 9. The upper edge of the pan is raised above the outer periphery of the lid, bent inward, and the outer periphery of the lid is fitted into the inner periphery of the pan, so that the soup does not spill outside the pan. Although it is proposed in Utility Model Registration No. 3008022 (Patent Document 4), all have a lid inside the upper edge of the pan, so there is a problem in hygiene when cooking.

本発明では、鍋本体及び蓋本体はアルミニウム製やステンレス製の絞り加工によるもので提供され、鍋本体の絞り傾斜部に連接される湾曲広径部と蓋本体に形成される傾斜面を含む湾曲座部とは、密着するものから、所定のシール空間を形成するものも提供され、また、鍋本体の立上がり周壁と蓋本体の内嵌周壁との間の密着性を解除する手段としては、該内嵌周壁に貫通して通気口を開口するものや、内嵌周壁の外面又は立上がり周壁の内面に空気導入溝を縦設するものがある。 In the present invention, the pan body and the lid body are provided by a drawing process made of aluminum or stainless steel, and include a curved wide-diameter portion connected to the diaphragm slope portion of the pan body and a curved surface formed on the lid body. The seat portion is provided so as to form a predetermined seal space from the close contact portion, and as a means for releasing the close contact between the rising peripheral wall of the pan body and the inner peripheral wall of the lid body, There are ones that penetrate the inner peripheral wall and open the vent hole, and others that have an air introduction groove formed vertically on the outer surface of the inner peripheral wall or the inner surface of the rising peripheral wall.

本発明の煮こぼれや吹きこぼれを防止できる蓋付き鍋Ａを実施例により説明すると、図１に示すように、鍋１は所要容積を有する鍋本体１aが、その上縁に内径方向に絞られる絞り傾斜部１bと、絞り傾斜部１bに連接して外方に湾曲する湾曲広径部１cとを有して成り、鍋１に被蓋される蓋２は、蓋本体２aの頂面に取っ手２bがビス２cで螺設され、その上部天面に蒸気排出口２dが開口され、その下方には湾曲広径部１cに着座する湾曲座部２eが形成されるとともに、その下面には絞り傾斜部１bに連続する傾斜面２fが形成され、湾曲座部２eの上方と天面間には所要の蒸気溜め空間３が形成されて成る。 An embodiment of the lid A with a lid that can prevent boiling and spilling according to the present invention will be described with reference to FIG. 1. As shown in FIG. The lid 2 covered with the inclined portion 1b and the wide-diameter portion 1c curved outwardly connected to the diaphragm inclined portion 1b is covered with a handle 2b on the top surface of the lid body 2a. Is screwed with a screw 2c, a steam discharge port 2d is opened on the upper top surface, a curved seat portion 2e seated on the curved wide diameter portion 1c is formed below, and a throttle inclined portion is formed on the lower surface thereof. An inclined surface 2f continuous with 1b is formed, and a required steam reservoir space 3 is formed between the upper side of the curved seat 2e and the top surface.

このようにして成る蓋付き鍋Ａは、煮炊きに使用されると内容物の煮炊きに伴い、水分は矢印に示すように、鍋本体１aの内周壁に沿って上昇する対流渦となり、上縁の絞り傾斜部１bと蓋本体２aの傾斜面２fとによって鍋本体１aの中央部に寄せられ、大きな泡となって破裂によって生じた蒸気は、広い蒸気溜め空間３の蒸気排出口２dより徐々に外部へ排出されるから、蓋２を押し上げて鍋本体１aの上縁から煮こぼれや吹きこぼれを排出することがない。 When the pan A with the lid thus formed is used for cooking, as the contents are cooked, the moisture becomes a convection vortex rising along the inner peripheral wall of the pan body 1a as shown by the arrow, Vapor generated by bursting as a large bubble is brought to the center of the pan body 1a by the throttle inclined portion 1b and the inclined surface 2f of the lid main body 2a, and gradually comes out from the steam outlet 2d of the large steam storage space 3. Therefore, the lid 2 is not pushed up to discharge any spilled or blown spills from the upper edge of the pan body 1a.

次に、図２に示した蓋付き鍋Ｂについて説明すると、鍋本体１aはその上部に形成される絞り傾斜部１bに連接して外方に湾曲する湾曲広径部１cに対して、その上方に末広がり状の立上がり周壁１dを連接して成り、蓋２は蓋本体２aの湾曲座部２eがその上方には立上がり周壁１dに内嵌する内嵌周壁２gを形成するとともに、その下方にはさらに内方に突出するように垂下されてその突端が折り返されて絞り傾斜部１bに連続する傾斜面２fが形成され、傾斜面２fの外端は湾曲広径部１cの湾曲面突端に干渉しない直径寸法に仕上げられるものであり、また、湾曲座部２eと傾斜面２fに囲まれる空間はシール空間２hとして形成されるものから、洗浄自在な弾性伸縮材から成るシール材（図外)を詰める部所としても利用されるものであり、さらに、立上がり周壁１dの周方向要所には通気口２iを開口して成る。 Next, the pan B with a lid shown in FIG. 2 will be described. The pan main body 1a is connected to the throttle inclined portion 1b formed on the upper portion thereof and is curved above the curved wide-diameter portion 1c that curves outward. The lid 2 has a curved seat portion 2e of the lid body 2a formed on the upper side thereof with an internal fitting peripheral wall 2g fitted inside the rising peripheral wall 1d, and further on the lower side thereof. An inclined surface 2f that hangs down so as to protrude inward and is bent back to form an inclined surface 2f that continues to the diaphragm inclined portion 1b is formed, and the outer end of the inclined surface 2f does not interfere with the curved surface protruding end of the curved wide-diameter portion 1c. The part that is finished to the dimensions, and the space surrounded by the curved seat 2e and the inclined surface 2f is formed as a seal space 2h, and is filled with a seal material (not shown) made of an elastic elastic material that can be washed. It is also used as a place, and A vent hole 2i is formed at a circumferential center of the girder peripheral wall 1d.

このようにして成る蓋付き鍋Ｂは、煮炊きに使用されると内容物の煮炊きに伴い、水分は矢印に示すように、鍋本体１aの内周壁に沿って上昇し、その対流渦は上部の絞り傾斜部１bから蓋本体２aの傾斜面２fに沿って鍋本体１aの中央部に寄せられ、大きな泡の破裂によって生じた蒸気は広い蒸気溜め空間３を経て徐々に蒸気排出口２dより外部へ排出される上、前記蓋付き鍋Ａより高い立上がり周壁１dに内嵌する内嵌周壁２gを有するから、蓋２を押し上げて鍋本体１aの上端から煮こぼれや吹きこぼれを排出することがない。
鍋本体１aから蓋２を外すときは、蓋本体２aの取っ手２bを持って周方向へ回すと、通気口２iにより立上がり周壁１dと内嵌周壁２gとの間の密着性が解除されるから、蓋２は軽く取り外される。 When the lid B with the lid is used for cooking, as the contents are cooked, the moisture rises along the inner peripheral wall of the pan body 1a as shown by the arrow, and the convection vortex is at the top. Vapor generated by bursting of large bubbles is gradually drawn from the steam discharge port 2d through the wide steam reservoir space 3 toward the center of the pan body 1a along the inclined surface 2f of the lid body 2a from the throttle inclined portion 1b. In addition to being discharged, since it has an internal fitting peripheral wall 2g that fits into the rising peripheral wall 1d higher than the lid A with the lid, the lid 2 is not pushed up to discharge boiled or blown out from the upper end of the pan body 1a.
When removing the lid 2 from the pan body 1a, if the handle 2b of the lid body 2a is held and rotated in the circumferential direction, the adhesiveness between the rising peripheral wall 1d and the inner fitting peripheral wall 2g is released by the vent 2i. The lid 2 is lightly removed.

以上のように本発明の蓋付き鍋Ａ、Ｂは複雑な構造によらず、絞り加工による鍋と蓋との組み合わせにより煮炊きに伴う煮こぼれや吹きこぼれを解消したものであり、調理に伴う調理台の汚れや火の始末に悩むことなく清潔で衛生的な調理に資するものである。 As described above, the pans A and B with lids of the present invention do not have a complicated structure, and are a combination of a pan and a lid by drawing to eliminate spills and spills associated with cooking, and a cooking table for cooking Contributes to clean and sanitary cooking without worrying about dirt and fire.
