Description
本発明は、調理用の鍋に被せて使用する鍋蓋に関するものである。 The present invention relates to a pot lid that is placed over a cooking pot.
調理用の鍋に被せて使用する鍋蓋において、内面に結露した水滴を料理材料に滴下するための突起を設けたものが知られている。
例えば、特許文献１（実開昭５７－９４４２６号公報）には、内面に同心円状の突起を設けた鍋蓋が開示され（特に、第１図及び第２図を参照）、特許文献２（実公平４－３０９８４号公報）には、内面に下向き頂角が鈍角の逆不等辺三角形断面形状を成す複数個の突状帯を断続的に列設した鍋蓋が開示され（特に、第２頁左欄第２８～３２行及び第１図を参照）、特許文献３（実用新案登録第３２００８０６号公報）には、内面に３本の同心円に沿って突状の水滴誘導部を多数形成した鍋蓋が開示されている（特に、段落００３４～００３５及び図１、３を参照）。
2. Description of the Related Art Pot lids that are placed over cooking pots are known to have projections on the inner surface that allow condensed water to drip onto cooking ingredients.
For example, Patent Document 1 (Japanese Utility Model Publication No. 57-94426) discloses a pot lid with concentric protrusions on its inner surface (see in particular Figures 1 and 2), Patent Document 2 (Japanese Utility Model Publication No. 4-30984) discloses a pot lid with a plurality of protruding bands arranged intermittently on its inner surface, each of which has an inverted scalene triangular cross-sectional shape with an obtuse downward apex angle (see in particular lines 28-32 in the left column on page 2 and Figure 1), and Patent Document 3 (Utility Model Registration No. 3200806) discloses a pot lid with a number of protruding water droplet guide portions formed on its inner surface along three concentric circles (see in particular paragraphs 0034-0035 and Figures 1 and 3).
しかし、特許文献１に開示されている鍋蓋の突起は同心円状であるため、鍋蓋の内面に発生した水滴を確実に鍋の内側に滴下させることができるが、鍋蓋が少しでも傾いていると、同心円状の突起に沿って一方向に水滴が集まってしまい、滴下する位置が集中してしまうという問題があり、特許文献２に開示されている複数個の突状帯は一重しかなく、特許文献３に開示されている多数の水滴誘導部の形成位置はまばらであるため、鍋蓋の内面に発生した水滴の一部は突状帯や水滴誘導部を通り抜けて鍋蓋の縁に達し、鍋の内側に滴下しないという問題があった。 However, because the projections on the pot lid disclosed in Patent Document 1 are concentric, water droplets that form on the inner surface of the pot lid can be reliably guided to the inside of the pot, but if the pot lid is tilted even slightly, the water droplets gather in one direction along the concentric projections, causing the problem that the droplets end up dripping in a concentrated location. The multiple protruding bands disclosed in Patent Document 2 are only single-layered, while the numerous water droplet guide parts disclosed in Patent Document 3 are sparsely formed, causing the problem that some of the water droplets that form on the inner surface of the pot lid pass through the protruding bands and water droplet guide parts to reach the edge of the pot lid and do not drip to the inside of the pot.
本発明は、上記の問題を解決し、鍋蓋の内面に発生した水滴を確実に鍋の内側に滴下させることができ、かつ、鍋蓋が傾いていても水滴の滴下位置が偏在しないようにすることを第１の課題とする。
また、調理中に発生する蒸気の抜けを適切に制御し、鍋の中の気流の動きを均一化して、各種の食材を美味しく調理できるようにすることを第２の課題とする。
To solve the above problems, and the first object of the present invention is to reliably drip water droplets generated on the inner surface of a pot lid onto the inside of the pot, and to prevent the dripping position of the water droplets from being unevenly distributed even if the pot lid is tilted.
The second objective is to properly control the escape of steam generated during cooking and to equalize the airflow inside the pot, thereby enabling various ingredients to be cooked deliciously.
請求項１に係る発明の鍋蓋は、
本体の内面に、該本体の中心を取り巻く複数の円形状突起又は前記本体の中心を取り巻く複数の周回突起からなる螺旋状突起が設けられており、
前記複数の円形状突起又は前記複数の周回突起には、それぞれ２以上１２以下の切れ目が形成されており、
前記複数の円形状突起又は前記複数の周回突起に形成されている切れ目のうち、隣接する円形状突起又は隣接する周回突起に形成されている切れ目が、前記本体の中心から延びる放射線上に並んでおらず、
前記本体の中央に穴が設けられ、前記本体の上面に前記穴の周囲を取り巻く把手が形成されているとともに、前記把手の上面を覆う小蓋を有しており、
前記小蓋は、前記把手の上面に載置される円板部及び該円板部の下面側に形成され外径が前記把手の内径より小さい円環部からなることを特徴とする。
The pot lid of the invention according to claim 1 is
A spiral projection consisting of a plurality of circular projections or a plurality of orbital projections surrounding the center of the body is provided on the inner surface of the body,
Each of the plurality of circular protrusions or the plurality of circumferential protrusions has 2 to 12 slits formed therein,
Among the slits formed in the plurality of circular protrusions or the plurality of circumferential protrusions, the slits formed in adjacent circular protrusions or adjacent circumferential protrusions are not aligned on radial lines extending from the center of the main body,
A hole is provided in the center of the body, a handle is formed on the upper surface of the body surrounding the periphery of the hole, and a small lid is provided to cover the upper surface of the handle,
The small lid is characterized by comprising a disk portion placed on the upper surface of the handle and a ring portion formed on the lower surface side of the disk portion and having an outer diameter smaller than the inner diameter of the handle .
請求項１に係る発明の鍋蓋は、本体の内面に、本体の中心を取り巻く複数の円形状突起又は本体の中心を取り巻く複数の周回突起からなる螺旋状突起が設けられており、複数の円形状突起又は複数の周回突起には、それぞれ２以上１２以下の切れ目が形成されているので、鍋蓋の内面に発生した水滴を鍋の内側に滴下させることができ、かつ、鍋蓋が傾いていても水滴の滴下位置の偏在を抑制することができる。
そして、複数の円形状突起又は複数の周回突起に形成されている切れ目のうち、隣接する円形状突起又は隣接する周回突起に形成されている切れ目が、本体の中心から延びる放射線上に並んでいないので、本体の内面を周辺に向かって流れ落ちる水滴が切れ目を通り抜けて本体の縁まで達することがほとんどなくなり、鍋蓋の内面に発生した水滴を確実に鍋の内側に滴下させることができる。また、鍋蓋が傾いている場合における水滴の滴下位置の偏在をより良く抑制することができる。
さらに、本体の中央に穴が設けられ、本体の上面に穴の周囲を取り巻く把手が形成されているとともに、把手の上面を覆う小蓋を有しているので、外蓋を用いることなく噴き出す蒸気の飛散を防止でき、鍋蓋のコストを低く抑えることができる。
加えて、小蓋は把手の上面に載置される円板部及び円板部の下面側に形成され外径が把手の内径より小さい円環部からなっているため、噴き出した蒸気が周囲に飛び散ることがなく把手の内側に溜まった水滴は穴から鍋の中に戻り煮汁の減少を抑えることができる。
また、調理中に発生する蒸気の抜けが適切に制御され、鍋の中の気流の動きが中央から立ち上がり周辺部に下降することとなって均一化する。そのため、各種の食材を美味しく調理できる。特に、ご飯を炊飯する場合に、非常に良い炊き上がり状態が得られる。
The pot lid of the invention of claim 1 has a spiral protrusion on the inner surface of the main body, consisting of a plurality of circular protrusions surrounding the center of the main body or a plurality of orbital protrusions surrounding the center of the main body, and each of the plurality of circular protrusions or the plurality of orbital protrusions has two to twelve slits formed therein, thereby enabling water droplets formed on the inner surface of the pot lid to drip inside the pot, and preventing the water droplets from dripping unevenly even if the pot lid is tilted.
Furthermore, among the slits formed in the multiple circular protrusions or multiple peripheral protrusions, the slits formed in adjacent circular protrusions or adjacent peripheral protrusions are not aligned radially extending from the center of the main body, so that water droplets flowing down the inner surface of the main body toward the periphery almost never pass through the slits and reach the edge of the main body, and water droplets generated on the inner surface of the pot lid can be reliably dripped inside the pot. Also, uneven distribution of water droplets when the pot lid is tilted can be better suppressed.
Furthermore, a hole is provided in the center of the main body, a handle is formed on the top surface of the main body surrounding the hole, and a small lid is provided to cover the top surface of the handle, so that the scattering of escaping steam can be prevented without the use of an outer lid, and the cost of the pot lid can be kept low.
In addition, the small lid consists of a disk portion placed on the top surface of the handle and a circular ring portion formed on the underside of the disk portion and with an outer diameter smaller than the inner diameter of the handle, so that the emitted steam does not splash around and the water droplets that accumulate inside the handle return to the pot through the holes, preventing the loss of broth.
In addition, the escape of steam generated during cooking is properly controlled, and the air flow inside the pot rises from the center and falls to the periphery, making it uniform. This allows a variety of ingredients to be cooked deliciously. In particular, when cooking rice, it produces a very good cooked rice.
以下、実施例によって本発明の実施形態を説明する。 The following describes the embodiment of the present invention using examples.
図１は実施例１に係る鍋蓋１の断面図及び内面の平面図であり、図２は実施例１に係る小蓋２の断面図及び内面の平面図である。
図１（Ａ）及び（Ｂ）に示すとおり、実施例１に係る鍋蓋１は、直径１５～３０ｃｍで弧状の断面を有する本体３、本体３の内面に、その中心を取り巻くように同心円状に設けられている４本の円形状突起４、本体３の中心に設けられている直径２～５ｍｍの穴５、本体３の上面に穴５の周囲を取り巻くように形成されている直径５～１０ｃｍ、高さ２～４ｃｍの略円筒状の把手６、把手６の上面を覆う直径６～１１ｃｍの小蓋２を有している。
４本の円形状突起４は、最も内側の直径が４～８ｃｍ、最も外側の直径が１４～２８ｃｍで、ほぼ等間隔に配置されており、いずれも幅３～６ｍｍ、高さ３～６ｍｍで下面側ほど幅が小さくなっている。そして、円形状突起４には、中心から十字状に延びる線に沿って切れ目７が形成され、それぞれ４つの弧状部に分割されている。
また、図２（Ａ）及び（Ｂ）に示すとおり、実施例１に係る小蓋２は、直径６～１１ｃｍ、厚さ６～１５ｍｍの円板部８と、外径が把手６の内径より少し小さく、高さが６～１５ｍｍの円環部９を有している。そして、円板部８の下面側で円環部９の外側には、幅２～５ｍｍ、深さ１～３ｍｍの溝１０が２箇所設けられている。
なお、実施例１における本体３及び小蓋２は、いずれも粘土に各種の粉末を混ぜて成形、焼成して製造される磁器又は陶器であるが、本発明の鍋蓋は、陶磁器に限定されるものではなく、各種金属の鋳物又はガラスや耐熱性樹脂を成形したものであっても良い。
FIG. 1 is a cross-sectional view and a plan view of the inner surface of a pot lid 1 according to the first embodiment, and FIG. 2 is a cross-sectional view and a plan view of the inner surface of a small lid 2 according to the first embodiment.
As shown in Figures 1(A) and (B), the pot lid 1 of Example 1 has a main body 3 with a diameter of 15 to 30 cm and an arc-shaped cross-section, four circular protrusions 4 arranged concentrically on the inner surface of the main body 3 around the center, a hole 5 with a diameter of 2 to 5 mm arranged in the center of the main body 3, a roughly cylindrical handle 6 with a diameter of 5 to 10 cm and a height of 2 to 4 cm formed on the top surface of the main body 3 so as to surround the periphery of the hole 5, and a small lid 2 with a diameter of 6 to 11 cm that covers the top surface of the handle 6.
The four circular protrusions 4 are arranged at approximately equal intervals, with an innermost diameter of 4-8 cm and an outermost diameter of 14-28 cm, and each has a width of 3-6 mm and a height of 3-6 mm, with the width decreasing toward the lower surface. Furthermore, slits 7 are formed along lines extending in a cross shape from the center of the circular protrusions 4, dividing each into four arc-shaped parts.
2A and 2B, the small cover 2 according to Example 1 has a disk portion 8 having a diameter of 6 to 11 cm and a thickness of 6 to 15 mm, and an annular portion 9 having an outer diameter slightly smaller than the inner diameter of the handle 6 and a height of 6 to 15 mm. Furthermore, on the lower surface side of the disk portion 8 and on the outside of the annular portion 9, two grooves 10 having a width of 2 to 5 mm and a depth of 1 to 3 mm are provided.
In addition, the main body 3 and small lid 2 in Example 1 are both made of porcelain or pottery produced by mixing clay with various powders, molding and firing the mixture, but the pot lid of the present invention is not limited to ceramics and may be made of various metal castings or molded glass or heat-resistant resin.
実施例１に係る鍋蓋１を用いると、調理中に発生した蒸気は本体３の内面で結露して水滴となるが、水滴がある程度の大きさになると、重力によって本体３の周辺側に移動し、４本の円形状突起４のいずれかにぶつかり、ぶつかった円形状突起４の側面を伝わって、その下面側から鍋の内側に滴下され、調理中の材料等の上に落ちる。
そして、鍋蓋１の本体３が、例えば図１（Ｂ）の右側に傾いていたとしても、左側にある円形状突起４にぶつかった水滴が、上下に延びる線に沿って形成されている切れ目７を越えて、右側にある円形状突起４に伝わってくることはないので、水滴の滴下位置が右側に偏ってしまうことがない。
また、本体３の中央には穴５が設けられているため、鍋の調理材料が沸騰して蒸気圧が高くなると、蒸気が穴５から噴き出すが、穴５の周囲を取り巻く把手６の上面は小蓋２で覆われているため、噴き出した蒸気が周囲に飛び散ることがなく、把手６の内側に溜まった水滴は穴５から鍋の中に戻るので、煮汁の減少を抑えることができる。
そして、小蓋２の下面外側には浅い溝１０が２箇所設けられているため、噴き出した蒸気が狭い隙間を通って適度に抜けていくので、小蓋２が安定した状態に保たれ、上下動による異音を抑制できるとともに、蒸気の抜ける位置が限定されるので安全である。
さらに、鍋の中の気流は中央から立ち上がり周辺部に下降して動きが均一な状態となるので、調理中の食材に均一に熱が回り、各種の食材を美味しく調理することができる。
When using the pot lid 1 of Example 1, steam generated during cooking condenses on the inner surface of the main body 3 and turns into water droplets. When the water droplets reach a certain size, they move due to gravity to the periphery of the main body 3, where they collide with one of the four circular protrusions 4, travel along the side of the circular protrusion 4 they collide with, drip from the underside of the protrusion into the inside of the pot, and fall onto the ingredients being cooked.
Furthermore, even if the main body 3 of the pot lid 1 is tilted, for example, to the right in Figure 1 (B), the water droplets that hit the circular protrusion 4 on the left side will not cross the slit 7 formed along the line extending vertically and reach the circular protrusion 4 on the right side, so the dripping position of the water droplets will not be biased to the right.
In addition, since a hole 5 is provided in the center of the main body 3, when the cooking ingredients in the pot boil and the steam pressure increases, steam gushes out from the hole 5. However, since the upper surface of the handle 6 surrounding the hole 5 is covered with the small lid 2, the gushes out steam does not scatter around, and the water droplets that have accumulated inside the handle 6 return to the pot through the hole 5, so that loss of broth can be suppressed.
And, two shallow grooves 10 are provided on the outer lower surface of the small lid 2, so that the ejected steam can escape moderately through narrow gaps, the small lid 2 is kept in a stable state, abnormal noise due to vertical movement can be suppressed, and the position where the steam escapes is limited, so that it is safe.
Furthermore, the air current inside the pot rises from the center and moves evenly down to the periphery, allowing heat to be distributed evenly to the ingredients being cooked, allowing a variety of ingredients to be cooked deliciously.
図３は実施例２に係る鍋蓋１１の断面図及び内面の平面図である。
実施例２に係る鍋蓋１１は、実施例１では本体３の内面に同心円状に４本の円形状突起４が設けられているのに対して、本体１３の中心を取り巻く４回転強の周回突起からなる螺旋状突起１４が設けられている点及び実施例１では中心から十字状に延びる線に沿って切れ目７が形成されているのに対して、螺旋状突起１４の内側の末端から８０度ずつずれた位置付近に切れ目１７が形成されている点で、実施例１に係る鍋蓋１と相違している。
そして、鍋蓋１１、本体１３、螺旋状突起１４及び切れ目１７以外の実施例１と同じ構成要素に対して、図３では図１に示す番号に１０を足した番号を付し、それらの構成要素については説明を省略する。
FIG. 3 is a cross-sectional view and a plan view of the inner surface of a pot lid 11 according to a second embodiment.
The pot lid 11 of Example 2 differs from the pot lid 1 of Example 1 in that, whereas in Example 1, four circular protrusions 4 are provided concentrically on the inner surface of the main body 3, a spiral protrusion 14 consisting of a protrusion that rotates approximately four times around the center of the main body 13 is provided, and, whereas in Example 1, the slits 7 are formed along lines extending in a cross shape from the center, slits 17 are formed near positions shifted by 80 degrees from the inner end of the spiral protrusion 14.
In addition, in Figure 3, the components that are the same as those in Example 1 other than the pot lid 11, main body 13, spiral protrusion 14, and slit 17 are given numbers that are 10 larger than the numbers shown in Figure 1, and descriptions of these components are omitted.
実施例２に係る鍋蓋１１を用いると、実施例１に係る鍋蓋１を用いた時の効果に加え、隣接する螺旋状突起１４に形成されている切れ目１７が、本体１３の中心から延びる放射線上に並ぶことがないので、本体１３の内面を周辺に向かって流れ落ちる水滴が切れ目１７を通り抜けて本体の縁まで達することがほとんどなくなる。
そのため、本体１３の内面に発生した水滴を確実に鍋の内側に滴下させることができ、また、鍋蓋１１が傾いている場合においても、多数の切れ目１７がばらばらに配置されていることから、螺旋状突起１４を伝わってくる水滴の滴下位置が偏ってしまうのを、実施例１の鍋蓋１以上に抑えることができる。
When using the pot lid 11 of Example 2, in addition to the effects achieved when using the pot lid 1 of Example 1, the slits 17 formed in adjacent spiral protrusions 14 do not line up on radial lines extending from the center of the main body 13, so that water droplets flowing down the inner surface of the main body 13 toward the periphery almost never pass through the slits 17 and reach the edge of the main body.
As a result, water droplets that form on the inner surface of the main body 13 can be reliably dripped onto the inside of the pot, and even if the pot lid 11 is tilted, since the numerous slits 17 are arranged at random, the drip position of water droplets traveling down the spiral protrusions 14 can be prevented from becoming biased more than with the pot lid 1 of Example 1.
図４は実施例３に係る鍋蓋２１の断面図及び内面の平面図である。
実施例３に係る鍋蓋２１は、実施例１では本体３が弧状の断面を有しているのに対して、本体２３が平板状である点、実施例１では本体３の内面に同心円状に４本の円形状突起４が設けられているのに対して、本体２３の内面に同心円状に８本の円形状突起２４、２４’が設けられている点、実施例１では全ての円形状突起４の高さが同じであるのに対して、最も内側及び最も外側の円形状突起２４’の高さが他の円形状突起２４の高さより高い点及び実施例１では中心から十字状に延びる線に沿って切れ目７が形成されているのに対して、中心から放射状に延びる１６本の線に沿って、切れ目２７が放射方向に隣接せず、かつ、周方向に放射状の線を跨がず隣接しないように形成されている点で、実施例１に係る鍋蓋１と相違している。
そして、鍋蓋２１、本体２３、円形状突起２４、２４’及び切れ目２７以外の実施例１と同じ構成要素に対して、図４では図１に示す番号に２０を足した番号を付し、それらの構成要素については説明を省略する。
FIG. 4 is a cross-sectional view and a plan view of the inner surface of a pot lid 21 according to a third embodiment.
The pot lid 21 of Example 3 differs from the pot lid 1 of Example 1 in that, while the main body 3 in Example 1 has an arc-shaped cross-section, the main body 23 is flat; while four circular protrusions 4 are provided concentrically on the inner surface of the main body 3 in Example 1, eight circular protrusions 24, 24' are provided concentrically on the inner surface of the main body 23; while all of the circular protrusions 4 in Example 1 have the same height, the height of the innermost and outermost circular protrusions 24' is higher than the height of the other circular protrusions 24; and, while the slits 7 in Example 1 are formed along lines extending cross-shaped from the center, the slits 27 are formed along 16 lines extending radially from the center, so that they are not adjacent in the radial direction and do not cross the radial lines in the circumferential direction.
4, the components that are the same as those in Example 1 other than the pot lid 21, the main body 23, the circular protrusions 24, 24', and the slits 27 are given numbers in which 20 is added to the numbers shown in FIG. 1, and descriptions of these components are omitted.
実施例３に係る鍋蓋２１による効果は、実施例１に係る鍋蓋１による効果及び実施例２に係る鍋蓋１１による効果と同じであるが、本体２３が平板状であることから、水滴を効率よく滴下させるため、円形状突起２４、２４’が実施例１より多く設けてある。
また、最も内側及び最も外側の円形状突起２４’の高さを、他の円形状突起２４の高さより高くしてある理由は、本体２３を平板状とするために、円形状突起２４、２４’を下面側にした状態で窯に入れて焼く必要があるためである。
なお、円形状突起２４、２４’の高さを全て同じにしても良いが、そうした場合、全ての円形状突起２４、２４’の下面に凹凸ができてしまい、見栄えが悪くなってしまう。
The effect of the pot lid 21 of Example 3 is the same as the effect of the pot lid 1 of Example 1 and the effect of the pot lid 11 of Example 2, but since the main body 23 is flat, more circular protrusions 24, 24' are provided than in Example 1 to allow water droplets to drip efficiently.
In addition, the reason why the height of the innermost and outermost circular protrusions 24' is made higher than the height of the other circular protrusions 24 is that in order to make the main body 23 flat, the circular protrusions 24, 24' need to be placed in an oven with the bottom facing up and fired.
It is possible to make all the circular protrusions 24, 24' the same height, but in that case, unevenness will be formed on the bottom surfaces of all the circular protrusions 24, 24', which will result in a poor appearance.
実施例１～３の変形例を列記する。
（１）実施例１の説明においては、各構成要素の寸法の範囲を示しているが、寸法は用途に応じて適宜決定されるため、説明で示した寸法の範囲に限定されるものではない。
（２）実施例１～３の本体３、１３、２３は、平面図の形状が円形であるが、楕円形や角の丸い多角形であっても良い。そうした場合、円形状突起４、２４、２４’や螺旋状突起１４を構成する周回突起も、楕円形や角の丸い多角形の突起とした方が良い。
（３）実施例１の本体３の内面には中心を取り巻く同心円状の４本の円形状突起４、実施例２の本体１３の内面には本体１３の中心を取り巻く４回転強の周回突起からなる螺旋状突起１４、実施例３の本体２３の内面には本体２３の中心を取り巻く同心円状の８本の円形状突起２４、２４’が設けられているが、円形状突起は同心円状でなくても良く、円形状突起の本数や周回突起の回転数は適宜選択可能である。
すなわち、鍋蓋本体の内面に、中心を取り巻く複数の円形状突起又は中心を取り巻く複数の周回突起からなる螺旋状突起が設けてあれば良い。

That is, the inner surface of the pot lid body may be provided with a plurality of circular protrusions surrounding the center, or a spiral protrusion consisting of a plurality of orbital protrusions surrounding the center.
（４）実施例１の円形状突起４には４つの切れ目７、実施例２の螺旋状突起１４には２周回あたり９つの切れ目１７、実施例３の内側２本の円形状突起２４、２４’には４つの切れ目２７、実施例３の外側６本の円形状突起２４、２４’には８つの切れ目２７が形成されているが、切れ目の形成数は適宜選択可能である。
ただし、切れ目の形成数が多すぎると、水滴が鍋蓋の縁に達し易くなるので、複数の円形状突起又は複数の周回突起には、それぞれ２以上２４以下の切れ目が形成されていれば良く、３以上１２以下の切れ目が形成されていればより良い。
（５）実施例２の螺旋状突起１４には内側の末端から８０度ずつずれた位置付近に切れ目１７が形成され、実施例３の円形状突起２４、２４’には中心から放射状に延びる１６本の線に沿って、切れ目２７が放射方向に隣接せず、かつ、周方向に放射状の線を跨がず隣接しないように形成されているが、要するに、本体１３又は２３の内面を周辺に向かって流下する水滴が、複数の切れ目１７又は２７を通り抜けにくければ良いので、隣接する円形状突起又は隣接する周回突起に形成されている切れ目が、本体の中心から延びる放射線上に並んでいなければ良い。
(4) In Example 1, four slits 7 are formed in the circular protrusion 4, in Example 2, nine slits 17 per two revolutions are formed in the spiral protrusion 14, in Example 3, four slits 27 are formed in the two inner circular protrusions 24, 24', and eight slits 27 are formed in the six outer circular protrusions 24, 24', but the number of slits can be selected as appropriate.
However, if too many slits are formed, water droplets will be more likely to reach the edge of the pot lid, so it is sufficient for the multiple circular protrusions or multiple circumferential protrusions to have 2 to 24 slits each, and it is even better if the multiple circular protrusions or multiple circumferential protrusions have 3 to 12 slits each.
(5) In the spiral protrusion 14 of Example 2, slits 17 are formed near positions shifted by 80 degrees from the inner end, and in the circular protrusions 24, 24' of Example 3, slits 27 are formed along 16 lines extending radially from the center so that they are not adjacent in the radial direction and are not adjacent to each other in the circumferential direction and do not cross any radial lines. In short, it is sufficient that water droplets flowing down the inner surface of the main body 13 or 23 toward the periphery do not easily pass through the multiple slits 17 or 27, so it is sufficient that the slits formed in adjacent circular protrusions or adjacent circumferential protrusions are not lined up on radial lines extending from the center of the main body.
（６）実施例１～３においては、本体３、１３、２３の中央に穴５、１５、２５が設けられ、上面に略円筒状の把手６、１６、２６が形成されているとともに、把手６、１６、２６の上面を覆う小蓋２、１２、２２を有しているが、これらは無くても良い。
また、把手６、１６、２６は、穴５、１５、２５の周囲を取り巻くように形成されていれば、略円筒状に限らず楕円筒状や角筒状等どのような形状でも良く、そうした場合、小蓋２、１２、２２及び円環部９も適当な形状に変更した方が良い。
（７）実施例１～３においては、小蓋２、１２、２２の下面側に、把手６、１６、２６の内径より少し小さい外径の円環部が形成されているが、円環部は無くても良く、また、把手６、１６、２６の外径より少し大きい内径の円環部を形成しても良い。
（８）実施例１～３においては、小蓋２、１２、２２の下面側で円環部９の外側に溝１０が２箇所設けられているが、これらは無くても良く、また、１箇所又は３か所以上設けても良い。
(6) In the first to third embodiments, a hole 5, 15, 25 is provided in the center of the main body 3, 13, 23, a roughly cylindrical handle 6, 16, 26 is formed on the upper surface, and a small lid 2, 12, 22 is provided to cover the upper surface of the handle 6, 16, 26, but these may be omitted.
Furthermore, as long as the handles 6, 16, 26 are formed to surround the holes 5, 15, 25, they may have any shape, such as an elliptical cylinder or a square cylinder, and in such a case, it is better to change the small lids 2, 12, 22 and the annular portion 9 to an appropriate shape.
(7) In Examples 1 to 3, a circular ring portion having an outer diameter slightly smaller than the inner diameter of the handle 6, 16, 26 is formed on the underside of the small lid 2, 12, 22. However, the circular ring portion may be omitted, or a circular ring portion having an inner diameter slightly larger than the outer diameter of the handle 6, 16, 26 may be formed.
(8) In the first to third embodiments, the grooves 10 are provided at two locations on the outer side of the annular portion 9 on the underside of the small lids 2, 12, 22. However, these may be omitted, and one or three or more grooves may be provided.
