Description

【0001】
【発明の属する技術分野】
本発明は、ジュース、食用油等の液体を収容した缶あるいは合成樹脂製容器に離脱自在に装着されて使用される合成樹脂製溢液受皿に関する。
【0002】
【従来の技術】
例えば食用油を収容した金属製の容器である缶において、食用油の使用時には、一般に缶の上壁の周縁部が缶用の孔あけ具あるいは缶切り等を利用して少なくとも1箇所開口される。四角い缶の場合、この開口箇所は一般に缶の上壁に記されている。そして予めその缶に合わせて用意された容器蓋が、容器蓋に配設された排液口が缶の上記開口の一つに整合されてその上壁を覆うように装着され、容器蓋の排液口から容器内の食用油が注出される。上記形態の容器蓋の典型例としては、例えば実公平4−54133号公報に開示された合成樹脂製容器蓋を挙げることができる。同公報に開示された容器蓋は、キャップ形状の取付け部材と、取付け部材に係合固定されたキャップ部材とから構成されている。取付け部材は頂壁と頂壁の周縁から垂下する筒状側壁とを有しており、側壁の下端部内周縁には容器の上端外周縁に係止される取付部が配設され、頂壁には円筒形状の排液口(口部)が立設されている。円筒形状の排液口の周囲には環状壁(周壁)が設けられ、排液口の外周面と環状壁との間には環状の溝が形成されている。キャップ部材は、軟質材からなる板と、板の前端部に設けられたキャップ体と、板の後端部に設けられた係合部とを含み、キャップ部材は板の係合部を介して取付け部材に係合固定されている。キャップ体は取付け部材の排液口を開口自在に閉塞している。以上のように構成された容器蓋は、その排液口が容器の上壁開口に整合されて容器の上壁を覆うよう取付部を介して装着され、食用油の使用時には容器蓋のキャップ体を開いて排液口を開口し、容器を注出方向に傾けて容器内に収容した食用油を排液口から適宜に注出する。
【0003】
【発明が解決しようとする課題】
上記従来の容器蓋においては、食用油の注出時におけるいわゆる液切れを良好にするために、取付け部材の頂壁に上記の如く排液口が立設されている。しかしながら、液体が特に食用油の如く粘性の比較的強い液体の場合には、注出終了直後における液切れを完全に除去することは、排液口の形状が種々改良された現状においても著しく困難であることは実用上明らかであり、未だにこの要求を完全に満足すべき容器蓋は得られていない。上記従来の容器蓋においては、注出終了直後における液切れを完全に除去することができないことに起因して、食用油が排液口の外周面に垂れ流れたり排液口から直接滴下したりする不具合が発生している。上記従来の容器蓋においては、排液口の外周面と環状壁との間に環状の溝が形成されているので、排液口の外周面に垂れ流れた食用油はこの溝内に一時的に回収することができる。しかしながら次に食用油を注出する場合には、容器蓋の傾きにより、上記溝内に回収された食用油が環状壁を乗り越えて垂れ流れたり、直接溝の外方に垂れ流れたりする不具合が生じていた。この課題を解消するため、上記溝を食用油の注出方向と反対の方向に下方に傾斜するよう形成し、更に傾斜した溝の最低部に容器の上壁開口と連通する戻し孔を形成した従来技術もすでに知られている。しかしながらこの従来技術においても、溝内に回収された食用油を容器内に完全に戻すことはできず、溝内における食用油の残留を防ぐことができないので、次に食用油を注出する場合には再び上記した如き不具合が発生してしまう。したがって上記従来の容器蓋を使用した場合には、食用油を注出した直後の排液口における液切れが不完全であることに起因して、排液口からその外周面に垂れ流れたりあるいは排液口から直接滴下した食用油が容器の側面を伝ってその底部まで垂れ流れ、容器の底部から落下してその下方の周辺を汚したり、容器が置かれる場所を汚す等の不具合を招いていた。
【0004】
本発明は上記事実に基づいてなされたものであり、その目的は、排液口から垂れ流れたり滴下した液体が容器の側面を伝ってその底部まで垂れ流れたとしても、容器の底部において受け止めて確実に収容することができ、その結果、容器の底部からの液体の落下を阻止してその下方の周辺の汚れを防止すると共に容器が置かれる場所を汚すことのない、新規な溢液受皿を提供することである。
【0005】
本発明の他の目的は、容器が液体の注出方向へ傾けられても容器の底部において既に収容された液体の流出を確実に防止することができる、新規な溢液受皿を提供することである。
【0006】
本発明の更に他の目的は、容器の底部において既に収容された液体を必要に応じて容易に排出することができる、新規な溢液受皿を提供することである。
【0007】
本発明の更に他の目的は、容器の底部への装着及び離脱が容易であると共に装着時には容器の底部にしっかりと係止される、新規な溢液受皿を提供することである。
【0008】
本発明の更に他の目的は、容器の底部の形状あるいは大きさにバラツキが存在したとしても、それらのバラツキを吸収して容器の底部にしっかりと係止される、新規な溢液受皿を提供することである。
【0009】
本発明の更に他の目的は、容器の底部のセンタリングが確実に遂行される、新規な溢液受皿を提供することである。
【0010】
本発明の更に他の目的は、成形が容易である、新規な溢液受皿を提供することである。
【0011】
本発明のその他の目的及び特徴は、本発明に従って構成された排液受皿の実施形態について添付図面を参照して詳細に説明する後の記載から明らかになるであろう。

【0014】
【発明の実施の形態】
以下、本発明の好適実施形態を図1〜図5を参照して更に詳細に説明する。なお図1〜図5において、実質上同一部分は同一符号で示されている。本発明に従って構成された溢液受皿200を説明する前に、先ず、本発明に従って構成された溢液受皿200が装着される金属製の缶100と、この缶100に装着される容器蓋2について説明する。図1を参照して、例えば、ポリプロピレンあるいはポリエチレン等の合成樹脂から一体に成形されるそれ自体周知の構成でよい容器蓋2は、実質上平坦でかつ円形状周縁を有する上壁4と、上壁4の周縁から垂下する円筒形状の側壁6とを有している。上壁4の周縁部には排液口8が形成されている。排液口8は上壁4から上方に延びる円筒形状の注出案内壁10を含んでいる。上壁4にはまた、注出案内壁10の基端部外周面を囲むように上方に延びる環状壁11が形成されている。環状壁11の高さは注出案内壁10よりも低く形成されている。注出案内壁10の外周面と環状壁11との間には環状の溝11aが形成されている。溝11aは缶100内の食用油の注出方向と反対の方向に下方に傾斜するよう形成され、傾斜した溝11aの最低部には、後述する缶100の上壁104に形成された開口112と連通する戻し孔11bが形成されている。この溝11a及び戻し孔11bは、注出案内壁10の外周面に垂れ流れた食用油を缶100内に回収するために設けられているものであるが、先に述べた如く、完全に回収することはできないので、食用油回収後の再注出時には溝11a内に残留する食用油が環状壁11を乗り越えて垂れ流れたり、直接溝11aの外方に垂れ流れたりする不具合が生じていた。
【0015】
上記環状壁11の外周面にはその全周にわたって被係止突条12が形成されている。注出案内壁10はキャップ14により開口自在に閉じられる。キャップ14は、円形状周縁を有する天壁16と、天壁16の周縁から垂下するスカート壁18とを備え、細長い柔軟なバンド20によって側壁6の上端に一体に連結されている。キャップ14のスカート壁18の開口端部の内周面には、その全周にわたって係止突条22が形成されており、また天壁16にはその内側から下方に延びる円筒形状のシール壁24が形成されている。キャップ14の係止突条22が注出案内壁10の被係止突条12に離脱自在に係止されかつキャップ14のシール壁24の外周面が注出案内壁10の開口端部の内周面に離脱自在に密着して嵌合されることにより、排液口8はキャップ14によって開口自在に閉じられる。容器蓋2の側壁6の開口端部の内周面には、その全周にわたって係止突条26が形成されており、また上壁4にはその内側から下方に延びる円筒形状のシール壁28が形成されている。
【0016】
それ自体周知の構成でよい缶100は、円筒形状の胴部102と、胴部102の上端及び下端にカール結合された上壁104及び底壁106とを備えている。したがって缶100の上端部外周面及び底部外周面にはカール結合部からなる環状突条108及び110が形成されている。缶100の上端部外周面及び底部外周面に環状突条108及び110が形成されていることに起因して、缶100の上面及び底面には円形凹部108a及び110aが形成される。胴部102が円形状の断面を有しているので、上壁104、底壁106、環状突条108及び110も円形状をなしている。上記説明から明らかなように、缶100は、その底部が円筒形状をなしその底面には円形凹部110aが形成された容器をなす。缶100内には図示しない食用油が収容されている。そして食用油の使用時には、缶100の上壁104の周縁部が例えば缶用の孔あけ具により開口される。番号112はこのようにしてあけられた開口を示している。缶100の上壁104に開口112が形成された後、容器蓋2がその排液口8が開口112に整合されて上壁104を覆うよう装着される。具体的には、容器蓋2は、その側壁6の内周面に形成された係止突条26が缶100の環状突条108の下面に係止され、シール壁28の外周面が環状突条108の内周面、すなわち缶100の上面に形成された円形凹部108aの内周面に密着して嵌合されることにより缶100に離脱自在に装着される。そして注出案内壁10からキャップ14を離脱して排液口8を開き、缶100を注出方向(図1において反時計方向)に傾けることにより食用油を注出案内壁10から所望のとおりに注出することができる。食用油の注出終了後、注出案内壁10はキャップ14により閉じられて次の使用に備えられる。
【0017】
次に、本発明に従って構成された溢液受皿200の実施形態について詳細に説明する。図1〜図3を参照して、例えば、ポリプロピレンあるいはポリエチレン等の合成樹脂から一体に成形することができる溢液受皿200は、円形状の周縁を有する平坦な底壁202と、底壁202の周縁から上方に延びる筒状側壁204と、側壁204の上端部内面から上方に向かって内方に傾斜して延びる状態(図3の2点鎖線参照)に成形した後に下方に向かって内方に向かって傾斜して延びる状態に折り返された(反転された)環状係止壁206とを具備している。円形の底壁202の上面であって側壁204の半径方向内側には複数個の突条208が形成されている。突条208の各々は、図2に示す如き平面図において、周方向に相互に間隔Dをおいてかつ溢液受皿200の軸心と共通の軸心を有する仮想円に沿って環状に延在するよう配列されている。したがって突条208の各々は、溢液受皿200の軸心と共通の軸心を有する円弧形状をなしている。突条208の各々の、底壁202の上面からの高さは一定に規定されると共に上記の如く折り返された係止壁206の自由端よりも低く規定されている。側壁204と環状に配列された突条208の各々との間で環状に延在する底壁202の上面には、周方向に相互に間隔をおいて半径方向に延びる複数個のリブ(凸部)210が全周にわたって形成されている。リブ210の各々の上面は実質上同一平面上に位置付けられている。なおこのリブ210は、図2においては図面の煩雑化を避けるために一部のみが示されている。
【0018】
図3に明示されているように、係止壁206の肉厚は側壁204に接続された基端から自由端に向かって漸次増大せしめられている。係止壁206の基端から自由端までの長さは周方向全長にわたり略一定であり、したがって図2に示される如く、成形後に折り返された状態で、上記自由端は溢液受皿200の軸心と共通の軸心を有する仮想円上に略位置付けられる。係止壁206の自由端部には周方向に間隔をおいて複数個の切欠き212が形成されている。
【0019】
上記した缶100の底部が溢液受皿200の側壁204内に導入されると、下方に向かって内方に向かって傾斜して延びる状態に折り返された係止壁206が缶100の底部に係止する。更に具体的に説明すると、缶100の底部が側壁204内に導入されると、係止壁206は弾性的に外方に強制されて缶100の底部外周面に弾性的に係止する。缶100の底部には環状突条110が形成されているので、係止壁206は環状突条110の上面に係止する。缶100の胴部102の表面と溢液受皿200の係止壁206の傾斜した上面との間には断面が略V形状をなす環状の溢液受止部Cが形成される。缶100の環状突条110の下面は溢液受皿200の底壁202の上面に形成されたリブ210の各々の上面に載置される。缶100の底部が側壁204内に導入されるとまた、突条208の各々の外周面が、缶100の底面に形成されている円形凹部110a内に進入せしめられて円形凹部110aの内周面を案内する。この案内作用を円滑に遂行するため、突条208の各々の上端外周縁は断面においてR形状にせしめられている(図3参照)。以上のようにして溢液受皿200は缶100の底部に装着(係止)される。
【0020】
先に述べた如く、食用油の注出終了直後における液切れを完全に除去することは著しく困難であり、したがって注出案内壁10の外周面に食用油が垂れ流れたりあるいは直接滴下したりする現象自体は防止することができない。このうち注出案内壁10の外周面に垂れ流れた食用油は、注出案内壁10の周囲に配設された溝11aにより一時的に回収することができるが、回収した食用油を完全に戻し孔11bから容器100内に戻すことはできず、食用油が残留する。そして次の食用油の注出時における容器蓋2の傾きにより、溝11a内に残留する食用油が環状壁11を乗り越えて垂れ流れたり、直接溝11aの外方に垂れ流れたりする。このようにして注出案内壁10及び溝11aから垂れ流れたり、直接滴下したりした食用油は、缶100の胴部102の表面を伝ってその底部に達する場合が生ずる。しかしながら缶100の底部に本発明に係る溢液受皿200を装着した場合においては、缶100の胴部102の表面を伝って底部まで垂れ流れた食用油は、先ず、胴部102の表面と溢液受皿200の係止壁206の傾斜した上面との間に形成される溢液受止部Cにより受け止められる。溢液受止部Cにより受け止められた食用油は、係止壁206の自由端部に形成された切欠き212のうちの何れかを介して溢液受皿200の内部に流出せしめられ、確実に収容される。その結果、缶100の底部からの食用油の落下を阻止してその下方の周辺の汚れを防止すると共に缶100が置かれる場所を汚すことが防止される。
【0021】
上記溢液受皿200の係止壁206の自由端部に形成された切欠き212の各々は、溢液受止部Cにより受け止めた食用油を溢液受皿200内に流出させ易くする機能を有しているが、切欠き212に代えて、図4に示すように開口(貫通孔)214を形成する実施形態もある。切欠き212に代えて開口214を係止壁206の自由端部に形成する場合には、開口214の各々をできるだけ係止壁206の自由端寄りに形成することが食用油の流出効果を向上させる上で好ましい。また上記切欠き212あるいは開口214に代えて、図5に示すように、係止壁206の少なくとも自由端部を周方向に向かう波形状216をなすように形成する実施形態もある。図5に示す実施形態の場合、溢液受止部Cにより受け止められた食用油は、波形状216の何れかの谷部を通って溢液受皿200内に円滑に流出させられる。
【0022】
溢液受皿200の係止壁206は、成形後、下方に向かって内方に向かって傾斜して延びる状態に折り返されているので、缶100したがって溢液受皿200が、食用油の注出方向へ傾けられても、溢液受皿200内に既に収容された食用油の流出を確実に防止することができるので、食用油の注出に際しても何ら問題はない。このような、既に収容された食用油の流出防止の観点から、係止壁206の自由端部に形成された切欠き212の各々又は開口214の各々は、自由端から比較的浅い位置に形成されることが望ましい。上記係止壁206は、上記の如く折り返されているので、注出案内壁10から垂れ流れたり滴下した食用油を受け止めた後、溢液受止部Cの底部に円滑に導入させることができる。係止壁206はいわゆるフラップと称される構成をなし、しかも側壁204の上端部内面から上方に向かって内方に傾斜して延びる状態に成形される(図3の2点鎖線参照)ので、それ自体の成形はきわめて容易であると共に成形後の型の無理抜きも容易に遂行することが可能である。溢液受皿200の、突条208、リブ210等を含むその他の構成もきわめて簡単であり、したがって溢液受皿200は、全体として容易に成形することが可能である。フラップと称される構成をなす係止壁206は成形後に下方に向かって内方に傾斜して延びる状態に折り返すことが容易に可能である。このように、係止壁206が、成形時には上記の如く成形し易い状態にせしめられ、成形後には上記の如き傾斜状態に折り返すことができるというユニークな構成は、食用油の注出時の傾きに対して既に収容された食用油の流出を防止する等の重要な目的を達成するための溢液受皿200を容易に成形することを可能にせしめるものである。実施形態においては、係止壁206の肉厚は、側壁204に接続された基端から自由端に向かって漸次増大せしめられているので、上記折り返しを一層容易にせしめる。
【0023】
上記した如く、缶100の底部が側壁204内に導入されると、係止壁206は、弾性的に外方に強制されて缶100の底部外周面に弾性的に係止する。このような弾性係止は、缶100の底部の形状あるいは大きさにバラツキが存在したとしても、それらのバラツキを吸収して缶100の底部に溢液受皿200をしっかりと係止せしめる。また缶100の底部には環状突条110が形成されているので、係止壁206は環状突条110の上面に係止する。このようにして、側壁204内に缶100の底部を挿入するだけの簡単な操作によって、溢液受皿200は缶100の底部に容易に装着される。溢液受皿200が缶100の底部に装着された状態において、係止壁206は環状突条110の上面に係止するが、係止壁206は上記の如く下方に向かって内方に傾斜して延びる状態に折り返されているので、係止壁206の上記弾性的係止と協動して缶100の底部と溢液受皿200との間の離脱方向の移動を効果的に阻止せしめ、溢液受皿200は缶100の底部にしっかりと係止される。また缶100の底部が溢液受皿200の側壁204内に導入されるに際し、底壁202の上面に形成された突条208の各々の外周面が、缶100の底面に形成されている円形凹部110a内に進入せしめられて円形凹部110aの内周面を案内するので、缶100の溢液受皿200に対するセンタリングが確実に遂行される。突条208はこれを1個の環状突条により形成する実施形態もあるが、複数に分割した形態の方が合成樹脂の使用量を節約できる。
【0024】
また、溢液受皿200における側壁204と環状に配列された突条208の各々との間で環状に延在する底壁202の上面にはリブ210が形成されているので、溢液受止部Cから流入した食用油をリブ210の各々の間を通して突条208の各々の内側の空間内に流出せしめ、溢液受止部Cから溢液受皿200内に流出された食用油の収容スペースを増大させることができる。また突条208の各々の半径方向外側において環状に延在する底壁202の上面の高さを、突条208の各々の半径方向内側における底壁202の上面の高さよりも高く形成し、突条208の各々の半径方向外側の上記底壁202の上面の、突条208の各々の周方向の間隔Dに対応した位置に、上記リブ210の各々に代えて複数の溝(凹部)を形成する実施形態もある。この実施形態においては、溢液受止部Cから流入した食用油を上記溝の各々の間を通して突条208の各々の内側の空間内に流出せしめ、溢液受止部Cから溢液受皿200内に流出された食用油の収容スペースを増大させることができる。
【0025】
フラップと称される構成をなす係止壁206は、上記の如く成型時の状態と使用時(装着時)の状態とに選択的に折り返し可能であるので、缶100と溢液受皿200とを相互に離脱方向に強制移動させることにより、係止壁206を成型時の状態に折り返しながら溢液受皿200は缶100の底部から容易に離脱せしめられる。このようにして缶100の底部から溢液受皿200を離脱せしめることにより、溢液受皿200から既に収容された食用油を容易に排出することが可能となる。
【0026】
以上、本発明を実施形態に基づいて添付図面を参照しながら詳細に説明したが、本発明は上記実施形態に限定されるものではなく、本発明の範囲を逸脱することなく、更に他の種々の変形あるいは修正が可能である。例えば、本発明に従って構成された溢液受皿200を、食用油を収容した缶100に適用した実施形態に基づいて説明したが、もちろんこの実施形態に限定される理由はなく、例えば、食用油を収容した合成樹脂製の容器、あるいはまた、食用油以外の他の液体、例えばジュース等の飲料水が収容された缶、合成樹脂製の容器、コーヒーカップ等のカップ類等に適用されることはいうまでもない。本発明に係る溢液受皿200が例えばコーヒーカップに適用される場合にはコースター的な使用形態となる。また上記実施形態において、缶100の底部が側壁204内に導入されると、係止壁206は、弾性的に外方に強制されて缶100の底部外周面に弾性的に係止するよう構成されているが、溢液受皿200の缶100への装着後、缶100の底部外周面と係止壁206の自由端との間に若干の隙間が存在する実施形態もある。この場合、缶100の底部外周面には環状突条110が形成されている必要があり、係止壁206が環状突条110の上面に係止することにより、溢液受皿200は缶100の底部に装着される。缶100の底部外周面と係止壁206の自由端との間の若干の隙間は、溢液受止部Cによって受け止めた食用油を溢液受皿200内に流出させる機能を有し、したがって係止壁206の自由端部に切欠き212、開口214あるいは波形状216を形成しない実施形態もある。本発明に係る溢液受皿200が、底部外周面に環状突条110が形成されていない容器に適用される場合には、溢液受皿200の容器への装着後、係止壁206が容器の底部外周面に弾性的に係止するよう構成される必要がある。
【0027】
更にはまた、上記実施形態において、本発明に係る溢液受皿200は円形状断面を有する缶100に適用可能に構成されているが、四角形状の断面を有する容器にも適用可能に構成される実施形態もある。その場合、溢液受皿は、実質上四角形状の周縁を有する底壁と、底壁の周縁から上方に延びる実質上四角形状をなす筒状の側壁とを備え、全体が実質上四角形状に形成される。そして、係止壁は、側壁の四つの角部を残した四つの部分の側壁の各々の上端部内面から、それぞれ上方に向かって内方に傾斜して延びる状態に成形した後に下方に向かって内方に向かって傾斜して延びる状態に折り返されるよう構成される。底壁の突条も側壁の各々の内側において実質上四角形状に配列される。このような構成を有する溢液受皿も形状が若干相違するのみで、本質的な特徴は上記した溢液受皿200と変わらないので、溢液受皿200と実質上同一の作用効果が達成される。更にはまた、上記実施形態において、環状係止壁206は、側壁204の上端部内面から上方に向かって内方に傾斜して延びる状態に成形した後に下方に向かって内方に向かって傾斜して延びる状態に折り返されるよう構成されているが、環状係止壁206の成形位置は実施形態の如き上端部内面に限定されるものではなく、側壁204の上部内面であれば成立する。

BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin overflow receiver that is used by being removably attached to a can or a synthetic resin container containing a liquid such as juice or edible oil.
[0002]
[Prior art]
For example, in a can which is a metal container containing edible oil, at the time of using the edible oil, generally the peripheral portion of the upper wall of the can is opened at least at one place by using a can punch or a can opener. In the case of a square can, this opening is generally marked on the top wall of the can. A container lid prepared in advance for the can is attached so that the drainage port provided in the container lid is aligned with one of the above openings of the can and covers the upper wall, and the container lid is drained. Edible oil in the container is poured out from the liquid port. As a typical example of the container lid of the said form, the synthetic resin container lid | cover disclosed by Japanese Utility Model Publication No. 4-54133 can be mentioned, for example. The container lid disclosed in the publication is composed of a cap-shaped attachment member and a cap member engaged and fixed to the attachment member. The mounting member has a top wall and a cylindrical side wall that hangs from the periphery of the top wall. A mounting portion that is locked to the outer periphery of the upper end of the container is disposed on the inner periphery of the lower end of the side wall. Is provided with a cylindrical drainage port (mouth). An annular wall (peripheral wall) is provided around the cylindrical drainage port, and an annular groove is formed between the outer peripheral surface of the drainage port and the annular wall. The cap member includes a plate made of a soft material, a cap body provided at the front end portion of the plate, and an engagement portion provided at the rear end portion of the plate, and the cap member is interposed via the engagement portion of the plate. It is fixedly engaged with the mounting member. The cap body closes the drainage port of the mounting member so as to be openable. The container lid configured as described above is mounted via an attachment portion so that the drain outlet is aligned with the upper wall opening of the container and covers the upper wall of the container, and when using cooking oil, the cap body of the container lid Is opened, the drainage port is opened, and the container is tilted in the pouring direction, and the edible oil contained in the container is appropriately poured out from the drainage port.
[0003]
[Problems to be solved by the invention]
In the conventional container lid described above, the drainage port is erected on the top wall of the mounting member as described above in order to improve the so-called drainage of the edible oil. However, when the liquid is a liquid having a relatively strong viscosity, such as edible oil, it is extremely difficult to completely remove the liquid shortage immediately after the end of pouring even in the current situation where the shape of the liquid discharge port is variously improved. It is clear from a practical point of view, and a container lid that completely satisfies this requirement has not yet been obtained. In the above-mentioned conventional container lid, edible oil drips on the outer peripheral surface of the drainage port or drops directly from the drainage port due to the fact that the liquid shortage immediately after the end of pouring cannot be completely removed. A malfunction has occurred. In the above conventional container lid, since an annular groove is formed between the outer peripheral surface of the drainage port and the annular wall, the edible oil that has flowed down on the outer peripheral surface of the drainage port is temporarily in this groove. Can be recovered. However, when the edible oil is poured out next, there is a problem that the edible oil collected in the groove drips over the annular wall or directly flows out of the groove due to the inclination of the container lid. It was happening. In order to solve this problem, the groove is formed so as to be inclined downward in the direction opposite to the edible oil pouring direction, and a return hole communicating with the upper wall opening of the container is formed at the lowest part of the inclined groove. Prior art is already known. However, even in this prior art, the edible oil collected in the groove cannot be completely returned to the container, and the edible oil cannot be prevented from remaining in the groove. In this case, the above-mentioned problem occurs again. Therefore, when the above conventional container lid is used, the drainage from the drainage port immediately after the edible oil is poured out is incomplete, so that it flows from the drainage port to the outer peripheral surface, or Edible oil dripped directly from the drainage port flows down the side of the container to the bottom, falls from the bottom of the container and stains the area around it, and causes problems such as soiling the place where the container is placed. It was.
[0004]
The present invention has been made on the basis of the above-mentioned facts, and the purpose of the present invention is to catch at the bottom of the container even if the liquid dripping or dripping from the drainage port flows down the side of the container to the bottom. A new overflow receiver that can be securely stored and, as a result, prevents liquid from falling from the bottom of the container to prevent contamination around the bottom of the container and does not contaminate the place where the container is placed. Is to provide.
[0005]
Another object of the present invention is to provide a novel overflow receiver that can surely prevent the liquid already contained in the bottom of the container from flowing out even if the container is tilted in the liquid dispensing direction. is there.
[0006]
Still another object of the present invention is to provide a novel overflow tray that can easily drain the liquid already contained in the bottom of the container as needed.
[0007]
Yet another object of the present invention is to provide a novel overflow pan that is easy to attach and detach to the bottom of the container and is securely locked to the bottom of the container when installed.
[0008]
Still another object of the present invention is to provide a novel overflow receiver that absorbs the variation even if there is variation in the shape or size of the bottom of the container and is firmly locked to the bottom of the container. It is to be.
[0009]
Yet another object of the present invention is to provide a novel overflow pan in which centering of the bottom of the container is reliably performed.
[0010]
Still another object of the present invention is to provide a novel overflow tray that is easy to mold.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to FIGS. 1 to 5, substantially the same parts are denoted by the same reference numerals. Before describing the overflow receiving tray 200 configured according to the present invention, first, the metal can 100 to which the overflow receiving tray 200 configured according to the present invention is mounted and the container lid 2 mounted to the can 100 will be described. explain. Referring to FIG. 1, for example, a container lid 2 which may be integrally formed from a synthetic resin such as polypropylene or polyethylene, which has a well-known configuration, includes an upper wall 4 having a substantially flat and circular peripheral edge, and an upper wall 4. It has a cylindrical side wall 6 depending from the periphery of the wall 4. A drainage port 8 is formed at the peripheral edge of the upper wall 4. The drainage port 8 includes a cylindrical extraction guide wall 10 extending upward from the upper wall 4. The upper wall 4 is also formed with an annular wall 11 extending upward so as to surround the outer peripheral surface of the base end portion of the dispensing guide wall 10. The height of the annular wall 11 is lower than that of the dispensing guide wall 10. An annular groove 11 a is formed between the outer peripheral surface of the extraction guide wall 10 and the annular wall 11. The groove 11a is formed so as to incline downward in a direction opposite to the direction in which the edible oil is poured into the can 100, and an opening 112 formed in the upper wall 104 of the can 100 described later is formed at the lowest part of the inclined groove 11a. A return hole 11b is formed in communication with the return hole 11b. The groove 11a and the return hole 11b are provided for collecting the edible oil dripping on the outer peripheral surface of the pouring guide wall 10 into the can 100. As described above, the groove 11a and the return hole 11b are completely recovered. Therefore, the edible oil remaining in the groove 11a drips over the annular wall 11 or flows directly out of the groove 11a at the time of re-pouring after collecting the edible oil. .
[0015]
Locked ridges 12 are formed on the outer peripheral surface of the annular wall 11 over the entire periphery. The dispensing guide wall 10 is closed by a cap 14 so as to be openable. The cap 14 includes a top wall 16 having a circular peripheral edge and a skirt wall 18 depending from the peripheral edge of the top wall 16, and is integrally connected to the upper end of the side wall 6 by an elongated flexible band 20. A locking protrusion 22 is formed on the inner peripheral surface of the open end of the skirt wall 18 of the cap 14, and a cylindrical sealing wall 24 extending downward from the inside of the top wall 16. Is formed. The locking protrusion 22 of the cap 14 is removably locked to the locked protrusion 12 of the extraction guide wall 10, and the outer peripheral surface of the seal wall 24 of the cap 14 is within the opening end of the extraction guide wall 10. The drainage port 8 is closed by the cap 14 so as to be freely opened by being closely and detachably fitted to the peripheral surface. On the inner peripheral surface of the opening end portion of the side wall 6 of the container lid 2, a locking protrusion 26 is formed over the entire periphery, and a cylindrical sealing wall 28 extending downward from the inside of the upper wall 4. Is formed.
[0016]
A can 100 having a configuration known per se includes a cylindrical body 102, and an upper wall 104 and a bottom wall 106 that are curled to the upper and lower ends of the body 102. Therefore, annular ridges 108 and 110 made up of curled joints are formed on the outer peripheral surface of the upper end and the outer peripheral surface of the can 100. Due to the annular protrusions 108 and 110 being formed on the outer peripheral surface of the upper end and the outer peripheral surface of the can 100, circular recesses 108 a and 110 a are formed on the top and bottom surfaces of the can 100. Since the trunk portion 102 has a circular cross section, the upper wall 104, the bottom wall 106, and the annular ridges 108 and 110 are also circular. As can be seen from the above description, the can 100 forms a container having a cylindrical bottom and a circular recess 110a formed on the bottom. In the can 100, edible oil (not shown) is accommodated. And when using edible oil, the peripheral part of the upper wall 104 of the can 100 is opened, for example by the punch for cans. The number 112 indicates the opening thus opened. After the opening 112 is formed in the upper wall 104 of the can 100, the container lid 2 is mounted so that the drainage port 8 is aligned with the opening 112 and covers the upper wall 104. Specifically, in the container lid 2, the locking ridge 26 formed on the inner peripheral surface of the side wall 6 is locked to the lower surface of the annular ridge 108 of the can 100, and the outer peripheral surface of the seal wall 28 is an annular ridge. It is attached to the can 100 so as to be detachable by closely fitting with the inner peripheral surface of the strip 108, that is, the inner peripheral surface of the circular recess 108 a formed on the upper surface of the can 100. Then, the cap 14 is removed from the pouring guide wall 10 to open the liquid discharge port 8, and the can 100 is tilted in the pouring direction (counterclockwise in FIG. 1) so that cooking oil can be supplied from the pouring guide wall 10 as desired. Can be poured out. After the end of the edible oil pouring, the pouring guide wall 10 is closed by the cap 14 to prepare for the next use.
[0017]
Next, an embodiment of the overflow receiver 200 configured according to the present invention will be described in detail. Referring to FIGS. 1 to 3, for example, an overflow tray 200 that can be integrally formed from a synthetic resin such as polypropylene or polyethylene includes a flat bottom wall 202 having a circular periphery and a bottom wall 202. A cylindrical side wall 204 extending upward from the peripheral edge and an inwardly extending state extending upward from the inner surface of the upper end portion of the side wall 204 (see the two-dot chain line in FIG. 3), and then inward downward And an annular locking wall 206 that is folded back (inverted) so as to extend in an inclined manner. A plurality of protrusions 208 are formed on the upper surface of the circular bottom wall 202 and on the radially inner side of the side wall 204. In the plan view as shown in FIG. 2, each of the protrusions 208 extends in an annular shape along a virtual circle having a distance D from each other in the circumferential direction and having a common axis with the axis of the overflow tray 200. Is arranged to do. Therefore, each of the protrusions 208 has an arc shape having a common axis with the axis of the overflow tray 200. The height of each of the protrusions 208 from the upper surface of the bottom wall 202 is defined to be constant and is defined to be lower than the free end of the locking wall 206 folded as described above. On the upper surface of the bottom wall 202 that extends in an annular shape between the side wall 204 and each of the annularly arranged protrusions 208, a plurality of ribs (convex portions) that extend in the radial direction at intervals in the circumferential direction are provided. ) 210 is formed over the entire circumference. The upper surface of each of the ribs 210 is positioned substantially on the same plane. Note that only a part of the rib 210 is shown in FIG. 2 in order to avoid complication of the drawing.
[0018]
As clearly shown in FIG. 3, the wall thickness of the locking wall 206 is gradually increased from the proximal end connected to the side wall 204 toward the free end. The length from the base end to the free end of the locking wall 206 is substantially constant over the entire length in the circumferential direction. Therefore, as shown in FIG. It is positioned approximately on a virtual circle having a common axis with the center. A plurality of notches 212 are formed at the free end of the locking wall 206 at intervals in the circumferential direction.
[0019]
When the bottom portion of the can 100 described above is introduced into the side wall 204 of the overflow receiving tray 200, the locking wall 206 folded back so as to extend inwardly downward is engaged with the bottom portion of the can 100. Stop. More specifically, when the bottom of the can 100 is introduced into the side wall 204, the locking wall 206 is elastically forced outward and elastically locked to the outer peripheral surface of the bottom of the can 100. Since the annular ridge 110 is formed at the bottom of the can 100, the locking wall 206 is engaged with the upper surface of the annular ridge 110. An annular overflow receiving portion C having a substantially V-shaped cross section is formed between the surface of the body portion 102 of the can 100 and the inclined upper surface of the locking wall 206 of the overflow receiving tray 200. The lower surface of the annular protrusion 110 of the can 100 is placed on the upper surface of each of the ribs 210 formed on the upper surface of the bottom wall 202 of the overflow receptacle 200. When the bottom portion of the can 100 is introduced into the side wall 204, the outer peripheral surface of each of the protrusions 208 is caused to enter the circular recess 110a formed on the bottom surface of the can 100, and the inner peripheral surface of the circular recess 110a. To guide you. In order to smoothly perform this guiding action, the outer periphery of the upper end of each of the protrusions 208 is formed in an R shape in cross section (see FIG. 3). As described above, the overflow receiver 200 is attached (locked) to the bottom of the can 100.
[0020]
As described above, it is extremely difficult to completely remove the liquid shortage immediately after the end of the edible oil pouring, so that the edible oil drips or drops directly on the outer peripheral surface of the pouring guide wall 10. The phenomenon itself cannot be prevented. Of these, the edible oil that drips on the outer peripheral surface of the pouring guide wall 10 can be temporarily collected by the grooves 11a disposed around the pouring guide wall 10, but the collected edible oil is completely removed. It cannot be returned from the return hole 11b into the container 100, and edible oil remains. Then, due to the inclination of the container lid 2 at the time of the next edible oil pouring, the edible oil remaining in the groove 11a flows over the annular wall 11 or directly flows outward of the groove 11a. In this way, the edible oil dripping from the dispensing guide wall 10 and the groove 11a or directly dripping may travel along the surface of the body portion 102 of the can 100 and reach the bottom thereof. However, when the overflow receiving tray 200 according to the present invention is attached to the bottom of the can 100, the cooking oil that has flowed down to the bottom along the surface of the body 102 of the can 100 first overflows the surface of the body 102. It is received by the overflow receiving part C formed between the inclined upper surface of the locking wall 206 of the liquid receiving tray 200. The edible oil received by the overflow receiving part C is allowed to flow into the overflow receiving tray 200 through any one of the notches 212 formed in the free end of the locking wall 206, and reliably. Be contained. As a result, it is possible to prevent the edible oil from falling from the bottom of the can 100 and prevent the surrounding area from being stained, and to prevent the can 100 from being soiled.
[0021]
Each of the notches 212 formed in the free end portion of the locking wall 206 of the overflow receiver 200 has a function of making it easy for the edible oil received by the overflow receiver C to flow out into the overflow receiver 200. However, instead of the notch 212, there is an embodiment in which an opening (through hole) 214 is formed as shown in FIG. When the opening 214 is formed at the free end of the locking wall 206 instead of the notch 212, it is possible to improve the outflow effect of edible oil by forming each of the openings 214 as close to the free end of the locking wall 206 as possible. This is preferable. Further, in place of the notch 212 or the opening 214, as shown in FIG. 5, there is an embodiment in which at least the free end of the locking wall 206 is formed so as to form a wave shape 216 in the circumferential direction. In the case of the embodiment shown in FIG. 5, the edible oil received by the overflow receiver C is smoothly discharged into the overflow receiver 200 through any valley of the corrugated shape 216.
[0022]
After the molding, the locking wall 206 of the overflow tray 200 is folded back in an inwardly extending state toward the lower side, so that the can 100 and thus the overflow tray 200 can be poured into the cooking oil. Even if the edible oil is inclined, it is possible to reliably prevent the edible oil already stored in the overflow receiving tray 200 from flowing out. From the viewpoint of preventing the already stored edible oil from flowing out, each of the notches 212 or each of the openings 214 formed at the free end of the locking wall 206 is formed at a relatively shallow position from the free end. It is desirable that Since the locking wall 206 is folded as described above, it can be smoothly introduced into the bottom of the overflow receiving part C after receiving the cooking oil dripping or dripping from the pouring guide wall 10. . Since the locking wall 206 has a so-called flap structure, and is formed so as to extend inwardly from the inner surface of the upper end of the side wall 204 (see the two-dot chain line in FIG. 3), Molding itself is very easy, and it is possible to easily remove the mold after molding. The other structures including the protrusion 208, the rib 210, etc. of the overflow tray 200 are also very simple. Therefore, the overflow tray 200 can be easily formed as a whole. The locking wall 206 having a configuration called a flap can be easily folded back into a state in which the locking wall 206 extends inwardly downward after molding. Thus, the unique structure that the locking wall 206 is made easy to be molded as described above during molding and can be folded back into the inclined state as described above after molding is the inclination when the cooking oil is poured out. On the other hand, it is possible to easily form the overflow receiver 200 for achieving an important purpose such as preventing the edible oil already contained from flowing out. In the embodiment, since the wall thickness of the locking wall 206 is gradually increased from the base end connected to the side wall 204 toward the free end, the folding is further facilitated.
[0023]
As described above, when the bottom portion of the can 100 is introduced into the side wall 204, the locking wall 206 is elastically forced outward and is elastically locked to the outer peripheral surface of the bottom portion of the can 100. Even if there is a variation in the shape or size of the bottom portion of the can 100, such elastic locking absorbs the variation and firmly holds the overflow receiving tray 200 on the bottom portion of the can 100. Since the annular ridge 110 is formed at the bottom of the can 100, the locking wall 206 is locked to the upper surface of the annular ridge 110. In this way, the overflow tray 200 is easily attached to the bottom of the can 100 by a simple operation of simply inserting the bottom of the can 100 into the side wall 204. In the state where the overflow tray 200 is mounted on the bottom of the can 100, the locking wall 206 is locked to the upper surface of the annular ridge 110, but the locking wall 206 is inclined inwardly downward as described above. Therefore, the movement in the separating direction between the bottom of the can 100 and the overflow tray 200 is effectively prevented by cooperating with the elastic locking of the locking wall 206. The liquid receiving tray 200 is firmly locked to the bottom of the can 100. In addition, when the bottom of the can 100 is introduced into the side wall 204 of the overflow receiving tray 200, the outer peripheral surface of each of the protrusions 208 formed on the top surface of the bottom wall 202 is a circular recess formed on the bottom surface of the can 100. Since it is made to enter into 110a and guides the inner peripheral surface of the circular recessed part 110a, the centering of the can 100 with respect to the overflow receptacle 200 is performed reliably. There is an embodiment in which the ridge 208 is formed by a single annular ridge, but the form divided into a plurality can save the amount of synthetic resin used.
[0024]
Moreover, since the rib 210 is formed in the upper surface of the bottom wall 202 extended cyclically between the side wall 204 in each overflow receiving tray 200 and each of the protrusions 208 arranged in an annular shape, the overflow receiving portion The edible oil flowing in from C is allowed to flow out between the ribs 210 and into the space inside each of the protrusions 208, and the storage space for the edible oil flowing out from the overflow receiving part C into the overflow receiving tray 200 is provided. Can be increased. In addition, the height of the upper surface of the bottom wall 202 extending annularly on the radially outer side of each of the protrusions 208 is formed higher than the height of the upper surface of the bottom wall 202 on the radially inner side of each of the protrusions 208. A plurality of grooves (recesses) are formed in place of the ribs 210 at positions corresponding to the circumferential distance D of the protrusions 208 on the upper surface of the bottom wall 202 on the radially outer side of the protrusions 208. There are also embodiments. In this embodiment, the edible oil that has flowed in from the overflow receiving part C is allowed to flow into the space inside each of the protrusions 208 through each of the grooves, and from the overflow receiving part C to the overflow receiving tray 200. The storage space for the edible oil that has flowed into the inside can be increased.
[0025]
Since the locking wall 206 having a configuration called a flap can be selectively folded back into a state at the time of molding and a state at the time of use (at the time of mounting) as described above, the can 100 and the overflow tray 200 can be connected to each other. By forcibly moving each other in the detaching direction, the overflow receiving tray 200 can be easily detached from the bottom of the can 100 while the locking wall 206 is folded back to the molding state. In this way, by detaching the overflow receiving tray 200 from the bottom of the can 100, it becomes possible to easily discharge the edible oil already stored from the overflow receiving tray 200.
[0026]
As mentioned above, although this invention was demonstrated in detail, referring an accompanying drawing based on embodiment, this invention is not limited to the said embodiment, Furthermore, various other various, without deviating from the scope of the present invention. Can be modified or modified. For example, the overflow tray 200 configured in accordance with the present invention has been described based on the embodiment applied to the can 100 containing edible oil, but of course there is no reason to be limited to this embodiment. Applied to containers made of synthetic resin, or cans containing other liquids other than edible oil, for example, drinking water such as juice, containers made of synthetic resin, cups such as coffee cups, etc. Needless to say. When the overflow tray 200 according to the present invention is applied to, for example, a coffee cup, it is used as a coaster. Moreover, in the said embodiment, when the bottom part of the can 100 is introduce | transduced in the side wall 204, the latching wall 206 will be forced outwardly elastically, and it is comprised so that it may latch elastically to the bottom outer peripheral surface of the can 100. However, in some embodiments, there is a slight gap between the outer peripheral surface of the bottom of the can 100 and the free end of the locking wall 206 after the overflow tray 200 is attached to the can 100. In this case, the annular protrusion 110 needs to be formed on the outer peripheral surface of the bottom of the can 100, and the overflow receiving tray 200 of the can 100 is secured by the locking wall 206 engaging with the upper surface of the annular protrusion 110. Mounted on the bottom. The slight gap between the outer peripheral surface of the bottom of the can 100 and the free end of the locking wall 206 has a function of causing the cooking oil received by the overflow receiving part C to flow into the overflow receiving tray 200, and therefore In some embodiments, the notch 212, opening 214, or corrugation 216 is not formed at the free end of the stop wall 206. When the overflow receiver 200 according to the present invention is applied to a container in which the annular protrusion 110 is not formed on the outer peripheral surface of the bottom, after the overflow receiver 200 is attached to the container, the locking wall 206 is the container. It is necessary to be configured to be elastically locked to the bottom outer peripheral surface.
[0027]
Furthermore, in the above embodiment, the overflow tray 200 according to the present invention is configured to be applicable to the can 100 having a circular cross section, but is also configured to be applicable to a container having a quadrangular cross section. There are also embodiments. In that case, the overflow tray is provided with a bottom wall having a substantially rectangular peripheral edge, and a cylindrical side wall having a substantially rectangular shape extending upward from the peripheral edge of the bottom wall, and is formed in a substantially rectangular shape as a whole. Is done. Then, the locking wall is formed so as to extend inwardly from the upper end inner surface of each of the four portions of the side wall except for the four corners of the side wall, and then downward. It is configured to be folded back into an inwardly extending state. The bottom wall protrusions are also arranged in a substantially rectangular shape inside each of the side walls. The overflow receiving tray having such a configuration is also slightly different in shape, and the essential features are the same as those of the overflow receiving tray 200 described above, so that substantially the same operational effects as the overflow receiving tray 200 are achieved. Furthermore, in the above-described embodiment, the annular locking wall 206 is formed so as to extend inwardly from the inner surface of the upper end of the side wall 204 and then inclines inward downward. However, the molding position of the annular locking wall 206 is not limited to the inner surface of the upper end portion as in the embodiment, and can be established if it is the upper inner surface of the side wall 204.

【The invention's effect】
According to the drainage tray according to the present invention, even if the liquid dripping or dripping from the drainage port flows down to the bottom of the container through the side of the container, it can be received and reliably accommodated at the bottom of the container. As a result, it is possible to prevent the liquid from falling from the bottom of the container to prevent the surrounding area from being contaminated and to prevent the area where the container is placed from being contaminated. Moreover, even if the container is tilted in the liquid pouring direction, it is possible to reliably prevent the liquid already stored at the bottom of the container from flowing out. Furthermore, the liquid already contained in the bottom part of the container can be easily discharged as needed. Furthermore, the container can be easily attached to and detached from the bottom of the container, and is securely locked to the bottom of the container at the time of attachment. Furthermore, even if there is a variation in the shape or size of the bottom of the container, the variation is absorbed and firmly secured to the bottom of the container. Furthermore, centering of the bottom of the container is reliably performed. Furthermore, it is easy to mold.
