Description

【０００１】
【発明の属する技術分野】
本発明は、特に活きている魚介類をそのままの状態を維持しながら移送したり、保管する場合に好適な魚介類用の容器に関する。
【０００２】
【従来の技術】
従来、上記容器としては、例えば実開平２−５５５６５号に示されるものが提案されている。これは、蓋体に形成した凹部内にエアポンプを収納し、前記エアポンプからのエアを案内するエア供給管を前記凹部の底部に形成した貫通孔を介して魚介類を所定量の海水又は水と共に入れた容器本体内に導入することで、エア供給管の先端に備えたエア吹き出し部からエアを海水中又は水中へ吹き出して、魚介類が酸欠状態になることがなく、活きた状態を維持しながら移送することができるようにしている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記容器には海水又は水が入っていることから、容器から海水又は水が漏れることがないように蓋にて容器本体を密閉状態にしなければならない。このため、容器本体内の水面上に魚介類が呼吸して出した排出ガス等が溜まり、それらを外部に排出することができない結果、容器内に新鮮な空気を取り入れることができず、魚介類にとって好ましくない環境になっていた。
上記不都合を解消するものとして、特許番号第２９３９０７１号に示されるように、容器の上端開口部を閉じるための蓋を、縦方向に貫通して容器内と連通して排気するための排気口となる貫通孔が形成された底壁部とこの底壁部の外周縁から上方に立ち上げた上方開放型の周壁とから構成し、前記蓋の底壁部上にエアポンプを載置し、蓋の上方開口部を閉じるための別の蓋に前記貫通孔からの排出エアを外部に排出したり、前記エアポンプへ新鮮な外部エアを供給するための空気案内用の上下方向の貫通孔を形成している。
上記蓋は、上端開口部を閉じる別の蓋を必要とするため、部品点数の増大によるコストの高騰を招く不都合がある。又、別の蓋に形成された上下方向の貫通孔を、外部から容易に見ることができるものであるため、容器としての外観が悪化し、商品価値が低下する不都合もあった。
又、蓋に貫通孔を形成することから、蓋自体の強度が低下する不都合もある。又、容器内のガスを蓋体の底壁部に形成した排出口から排出し、エアポンプと共通の貫通孔（別の蓋に形成した孔）を通して容器内のガスの排出とエアポンプへのエアの吸入とを行う構成であるため、良好な排出が行えない不都合もあり、改善の余地があった。
【０００４】
本発明が前述の状況に鑑み、解決しようとするところは、外観を損ねることがなく、貫通孔の形成による蓋の強度低下も回避することができ、しかも容器内の気体を良好に排出することができる容器を提供する点にある。
【０００５】
【課題を解決するための手段】
本発明の容器は前述の課題解決のために、上方が開放された容器本体と、この容器本体の開口部を閉じる蓋体とからなり、前記容器本体及び蓋体のうちの一方にエア供給装置用収納部を備えさせ、前記容器本体と蓋体とを凹凸嵌合により閉蓋固定するための嵌合凸部を該容器本体及び蓋体のうちの一方に備えさせ、かつ、嵌合凹部を該容器本体及び蓋体のうちの他方に備えさせ、前記嵌合凸部と嵌合凹部の接合面間に周方向に連続する通気用間隙を形成し、前記通気用間隙に容器内部と連通するための入口側連通部及び該入口側連通部と周方向で異なる位置にて該通気用間隙に容器外部と連通するための出口側連通部を前記容器本体及び蓋体の少なくとも一方に形成したことを特徴としている。
上記のように容器本体と蓋体とを閉蓋固定するために備えられる嵌合凸部と嵌合凹部の接合面間に周方向に連続する通気用間隙を形成し、通気用間隙に容器内部と連通するための入口側連通部及び入口側連通部と周方向で異なる位置にて通気用間隙に容器外部と連通するための出口側連通部を容器本体又は蓋体に形成するだけで、容器内に溜まったガス等を外部に確実に排出することができる。しかも、通気用間隙を周方向に連続して形成しているので、例え容器本体内の海水又は水の一部が入口側連通部から入り込んだとしても、周方向に沿って形成された通気用間隙を介して出口側連通部に案内されて外部に排出されることがない、又は非常に少ない。又、蓋体に貫通孔を形成していないので、外観が悪化したり、蓋体の強度が低下するといったことがない。又、上記のように嵌合凹凸部を利用して通気を行う構成にすることによって、容器本体内に貯留している水や海水の中にエアを供給するエア供給装置を、蓋体又は容器本体のどの箇所へも装着可能になる。尚、前記エア供給装置は、乾電池等の二次電池を内蔵する携帯用のエアポンプであってもよいし、例えば輸送用車両から電源供給を行って駆動可能な二次電池等の電源を持たないエアポンプであってもよい。
【０００６】
前記出口側連通部に連通して上方へ通気を行うための通気用溝を前記蓋体の外壁面に形成することによって、外壁面が接触した状態で水平方向に多数の容器を配置して保管したり、移送する場合でも通気用溝を介して通気が可能になる。
【０００７】
前記容器が、平面視において４つの角部を備えたほぼ矩形状に構成され、前記通気用間隙を、少なくとも１つの角部を挟んで２つの辺に渡る状態で形成することによって、角部が海水や水の流動抵抗になるため、通気用間隙を直線状に形成した場合に比べて、入口側連通部を介して通気用間隙内に入り込んだ海水や水が通気用間隙の出口側連通部へ移動し難い。
【０００８】
前記エア供給装置が乾電池等の二次電池により駆動される携帯用のエアポンプからなり、前記蓋体に前記エアポンプを構成するポンプ本体を収納するための前記エア供給装置用収納部としての凹部を形成し、前記凹部の上方を覆うために蓋体の表面と面一となる上面を備えたカバー体を嵌合により着脱自在に設け、前記カバーを取り付けた状態において該カバー体の横側面の一部を露出させるために前記蓋体の凹部特定箇所から該蓋体の外周縁にかけて凹溝部を形成し、前記凹溝部の上面と該カバー体の露出した下面との間に隙間を形成させて前記エア供給装置用収納部としての凹部と外部とを連通させている。
上記のように構成することによって、カバー体の横側面に凹溝部を介して指を接触させることができるから、カバー体を指にて持ち上げて容易に取り外すことができる。しかも、その凹溝部に形成された隙間を、エアポンプの給排気用の開口に利用することができる。
【０００９】
前記通気用間隙が前記嵌合凸部の頂部表面と前記嵌合凹部の底部表面との間に形成され、前記通気用間隙を形成する下面が、前記出口側連通部側ほど上方に位置する傾斜面に形成することによって、入口側連通部を介して通気用間隙内に入り込んだ海水や水が入口側連通部側へ移動案内されることから、通気用間隙を形成する下面を水平面に形成したものに比べて、出口側連通部へ移動し難くい。
【００１０】
【発明の実施の形態】
図１、図２及び図９に、本発明の魚介類を活きたままの状態を維持しながら移送したり（図９では水の中に魚Ｆを入れた状態を示している）、魚介類を活きたままの状態を維持しながら保管する場合に用いる魚介類用の容器の実施態様を示している。この容器は、上方が開放された平面視ほぼ長方形の発泡合成樹脂製の容器本体１と、この容器本体１の開口部１Ｋを閉じる平面視ほぼ長方形の発泡合成樹脂製の蓋体２とからなり、前記蓋体２にエア供給装置であるエアポンプ３を収納するためのエア供給装置用収納部としての凹部２Ｇを形成している。ここでは、平面視ほぼ長方形の容器を示しているが、正方形又は多角形あるいは円形等、どのような形状でもよいが、矩形状（長方形又は正方形）の容器とする場合には、車両等に多数積み込んで移送する場合に載置効率面で最適であり、又、円形の容器とする場合には、持ち運ぶ場合に有利になる。ここでは、軽量でコスト面において有利な発泡合成樹脂製の容器を示しているが、非発泡の合成樹脂で構成したものであってもよい。
【００１１】
前記容器本体１は、ほぼ長方形状の底板部１Ａと、この底板部１Ａの外周縁から立ち上げられて外周壁を構成する４枚の縦板部１Ｂ，１Ｃ，１Ｄ，１Ｅとからなっているが、前述のように容器本体１の形状は、図に示されるもの以外であってもよい。又、前記縦板部１Ｂ，１Ｃ，１Ｄ，１Ｅの上端面の内方側部分に、上方に突出し、かつ、周方向全域に渡る環状の嵌合凸部１Ｔを形成している。この嵌合凸部１Ｔを、後述する蓋体２の嵌合凹部２Ｈに嵌合することによって、容器本体１に蓋体２を閉蓋状態で固定することができるようになっている。ここでは、嵌合凸部を容器本体１に備えさせ、嵌合凹部を蓋体２に備えさせているが、嵌合凸部を蓋体２に備えさせ、嵌合凹部を容器本体１に備えさせて実施することもできる。尚、嵌合凸部を蓋体２に備えさせ、嵌合凹部を容器本体１に備えさせて実施する場合には、容器本体１に後述する入口側連通部１２及び出口側連通部１３を形成することになる。又、前記嵌合凸部及び嵌合凹部を全周に渡って備えさせる方が嵌合力や密閉性（シール性）において有利であるが、周方向の一部にのみ嵌合凸部及び嵌合凹部を備えさせることもできる。本発明では上述のごとく、前記嵌合凸部１Ｔと嵌合凹部２Ｈとから容器本体１と蓋体２とを閉蓋固定するための嵌合手段を構成している。
【００１２】
前記蓋体２は、図１〜図４に示すように、ほぼ長方形状の天板部２Ａと、この天板部２Ａの外周縁から下方に垂設してスカート部を構成する４枚の縦壁部２Ｂ，２Ｃ，２Ｄ，２Ｅとからなっているが、前述のように蓋体２の形状は、図に示されるもの以外であってもよい。又、前記縦壁部２Ｂ，２Ｃ，２Ｄ，２Ｅの下端面の厚み方向のほぼ中央部分に、溝部となる嵌合凹部２Ｈを周方向全域に渡って形成している。この嵌合凹部２Ｈが、前述したように容器本体１の嵌合凸部１Ｔに嵌合して容器本体１と蓋体２とを嵌合固定するのである。
【００１３】
又、図２に示すように、前記天板部２Ａの縦壁部２Ｅ寄り箇所（どこでもよい）に、前記凹部２Ｇを形成し、この凹部２Ｇの上方を覆うために蓋体２の表面（上面）と面一となる上面を備えたほぼ長方形状の発泡合成樹脂製のカバー体４を嵌合により着脱自在に設けている。前記カバー体４の周面に、周方向全域に渡る凸部４Ｔを形成してあり、カバー体４が凹部２Ｇから外れ難いようにしているが、凸部４Ｔを省略して実施することもできる。
【００１４】
又、図２、図５及び図９に示すように、前記凹部２Ｇ内に、前記エアポンプ３の水平方向での不測の移動を阻止するための位置決め用のほぼＬ字形状となる突出部５を形成すると共に、前記凹部２Ｇを構成する底板部７の上面のうち、前記突出部５と前記凹部２Ｇを形成する縦壁部８とで囲まれる部分の上面に、前記エアポンプ３を載置支持するための帯板状の凸部６の複数を形成している。従って、特別な固定手段等を設けなくても、容器の運搬時等にエアポンプ３が不測に移動することを阻止することができる。又、凹部２Ｇ内に多少の海水や水が入った場合でも、凸部６に載置された底板部７の上面よりも高く位置したエアポンプ３内に海水や水が入ることを阻止することができるから、防水性を有しない安価なエアポンプ３を使用することができる利点がある。しかし、突出部５や凸部６を省略して実施することもできる。尚、前記突出部５と前記凹部２Ｇを形成する縦壁部８とで囲まれる部分以外の底板部７の上面にも、前記帯板状の凸部６を形成している。
【００１５】
図２及び図５に示すように、前記カバー体４の横側面（凸部４Ｔを備えた面）の一部を露呈するために前記蓋体２に前記凹部２Ｇの特定箇所から蓋体２の外周縁にかけて凹溝部９を形成している。従って、凹溝部９を介してカバー体４の横側面の一部に指を接触させてカバー体４を上方に持ち上げることで容易に取り外すことができるようにしている。又、前記凹溝部９上面と該カバー体４の下面との間に該カバー体４にて閉塞された凹部２Ｇ内の空間と外部とを連通するための隙間１０を形成して、この隙間１０を通して前記エアポンプ３に対する給排気を行うことができるようにしている。前記凹溝部９の底面は、図５に示すように外周縁に近い側ほど下方に位置する傾斜面に構成して凹溝部９にかかる水や海水が凹部２Ｇ内に入り込み難くしているが、水平面に形成してもよい。
【００１６】
図３、図４、図６〜図８に示すように、前記嵌合凸部１Ｔと嵌合凹部２Ｈの接合面間に周方向において特定範囲に渡って連続する通気用間隙Ｓを形成するために該蓋体２の嵌合凹部２Ｈの一部に他の部分よりも上方に位置する凹溝部１１を形成し、前記通気用間隙Ｓの始端部に容器内部と連通するための入口側連通部１２を蓋体２に形成し、この入口側連通部１２と周方向で異なる位置、つまり前記通気用間隙Ｓの終端部に容器外部と連通するための出口側連通部１３を蓋体２に形成することにより、容器内のガス等を入口側連通部１２、通気用間隙Ｓ、出口側連通部１３を通して外部に排出することができるようにしている。尚、前記入口側連通部１２、通気用間隙Ｓ、出口側連通部１３を１個ずつ設けた場合を示したが、複数（２個以上）設けて実施してもよい。
【００１７】
前記入口側連通部１２が、蓋体２の嵌合凹部２Ｈを形成する内側縦壁面２Ｍよりも内側に位置する上下面を有する第１凹部１２Ａと、この第１凹部１２Ａの下端から内側に水平方向に延びると共に蓋体２の底面（下面）よりも上方に位置する水平上面を有する第２凹部１２Ｂとから構成されているが、通気用間隙Ｓに連通することができるものであればどのような形状のものであってもよい。
前記出口側連通部１３が、蓋体２の嵌合凹部２Ｈを形成する外側縦壁面２Ｎよりも外側に位置する上下面を有する第１凹部１３Ａと、この第１凹部１３Ａの下端から外側に水平方向に延びると共に蓋体２の底面（下面）よりも上方に位置する水平上面を有する第２凹部１３Ｂとから構成されているが、通気用間隙Ｓに連通することができるものであればどのような形状のものであってもよい。
前記通気用間隙Ｓは、１つの長辺とこれに隣り合う１つの短辺との間（２つの辺の間）、つまり前記縦壁部２Ｃの周方向ほぼ中央箇所から角部Ｋを挟んで隣り合う他の前記縦壁部２Ｄの周方向ほぼ中央箇所に渡って形成されているが、通気用間隙Ｓの形成箇所及び形成長さは自由に変更できる。又、前記通気用間隙Ｓを嵌合凸部１Ｔの頂部表面（上面）と嵌合凹部２Ｈの底部表面（底面）との間に形成しているが、嵌合凸部１Ｔの内側に位置する縦壁部又はこの縦壁部に対向位置する嵌合凹部２Ｈを構成する内側の縦壁部にそれの壁面よりも凹んだ溝部を形成して通気用間隙Ｓを構成してもよいが、この場合には、容器本体１及び蓋体２をそれぞれ成形するための金型構造が複雑になり、製造コストが高くなる不都合がある。
【００１８】
図７に示すように、前記凹溝部１１の幅（図において左右の寸法）を嵌合凹部２Ｈの幅よりも小さく形成することによって、凹溝部１１の容器内外方向両側に位置する嵌合凹部２Ｈの底面とこれに対応する嵌合凸部１Ｔの上面とが接当する状態になり、容器本体１と蓋体２との嵌合を安定良く行うことができるが、図１５に示すように、凹溝部１１の幅（図において左右の寸法）を嵌合凹部２Ｈの幅と同一にして実施してもよい。この場合には、嵌合凸部１Ｔの上面が嵌合凹部２Ｈの底面に全く接当しない状態になる。又、前記凹溝部１１を、図１６に示すように、嵌合凸部１Ｔに形成して通気用間隙Ｓを形成することもできる。
【００１９】
図３では、前記入口側連通部１２及び出口側連通部１３を凹溝部１１の始端部と終端部にそれぞれ形成したが、図１３に示すように、凹溝部１１の始端部１１Ｅ及び終端部１１Ｆから凹溝部１１の中間部側に少し寄った位置に入口側連通部１２及び出口側連通部１３を形成してもよい。又、前記凹溝部１１を嵌合凹部２Ｈの全域に渡る環状に形成し、その環状に形成された凹溝部１１の途中に入口側連通部１２及び出口側連通部１３をそれぞれ形成してもよい。
【００２０】
図４、図６、図９に示すように、前記縦壁部２Ｄに、前記出口側連通部１３に連通して上方へ通気を行うための縦向きの通気用溝１４を形成している。従って、図１０に示すように、外壁面が接触した状態で水平方向に多数の容器（図では２個）を配置して保管したり、移送する場合でも出口側連通部１３からのエアを通気用溝１４を介して上方に移動させた後、外部に排出することができる利点がある。図では通気用溝１４を上下方向に沿った向きに形成したが、少し斜めとなる方向に沿う向きであってもよい。
【００２１】
前記エアポンプ３は、図２及び図９に示すように、乾電池等の二次電池及びこの二次電池により駆動されるポンプ（図示せず）がケースに内装されたポンプ本体３Ａと、このポンプからのエアを容器内に案内するために前記底板部７に貫通させたエア供給管としてのチューブ３Ｂと、チューブ３Ｂの先端に取り付けられて泡状にエアを吹き出すためのエア吹き出し部３Ｃとからなっているが、他の構成であってもよい。図には示していないが、前記エア吹き出し部３Ｃを容器本体１に固定する固定手段として、例えば容器本体１の底板部１Ａの上面に上方に突出する一対の係止部を容器本体１に一体形成して実施してもよい。
【００２２】
前記エアポンプ３を、図１１に示すように容器本体１に備えさせて実施することもできる（図では蓋体２を省略している）。つまり、エアポンプ３を収納するために、容器本体１の水平方向に延出する延出部１Ｇを容器本体１に一体形成し、この延出部１Ｇにて形成される空間を２分割し、一方の空間１Ｓにエアポンプ３のポンプ本体３Ａを収納している。前記他の空間１Ｗを設けることによって、チューブ３Ｂを容器本体１内に挿入するために該容器本体１に形成した切欠き１Ｎを通して容器本体１内の水又は海水の一部が入り込んでも、空間１Ｗに入り込むだけでポンプ本体３Ｂ側の空間１Ｓにまで入り込むことを回避することができるようにしている。尚、図１１に示す１Ｍは、空間１Ｗ又は１Ｓ内に入り込んだ水又は海水を外部に排出するための排出孔であるが、無くてもよい。
【００２３】
図１２に示すように、前記通気用間隙Ｓを形成する下面、つまり嵌合凸部１Ｔの頂部表面（上面）１Ｕが、出口側連通部側（図では右側）ほど上方に位置する傾斜面（図では所定角度Ｘを有する傾斜面）に形成して実施してもよい。このように傾斜面とすることで、例え入口側連通部１２から水又は海水が入り込んだとしても、その水又は海水が、傾斜面にて入口側連通部１２側へ傾斜案内されるため、出口側連通部１３に達することを阻止することができるようにしている。前記傾斜面の所定角度は、どのような角度に設定してもよいが、小さい角度の方が形成し易い利点がある。
【００２４】
【発明の効果】
請求項１の発明によれば、容器本体と蓋体とを閉蓋固定するために本来的に備えさせる嵌合凸部と嵌合凹部の接合面間に通気用間隙を形成し、通気用間隙に容器内部と連通するための入口側連通部及び容器外部と連通するための出口側連通部を形成するだけで、容器内の気体を外部に良好に排出することができる。しかも、通気用間隙を周方向に形成しているので、例え容器本体内の海水又は水の一部が入口側連通部から入り込んだとしても、周方向に形成された通気用間隙を介して出口側連通部に案内されて外部に排出されることがない、又は非常に少なくでき、取扱面において有利な容器とすることができる。又、蓋体に貫通孔を形成していないので、外観が悪化したり、蓋体の強度が低下するといったことがなく、商品価値を高めることができる。又、上記のように嵌合凹凸部を利用して通気を行う構成にすることによって、容器本体内にエアを供給するエア供給装置を、蓋体又は容器本体のどの箇所へも装着可能になり、どのような容器にも取り付け可能な設計の自由度を高めることができる。
【００２５】
請求項２の発明によれば、出口側連通部に連通して上方へ通気を行うための通気用溝を前記蓋体の外壁面に形成することによって、外壁面が接触した状態で水平方向に多数の容器を配置して保管したり、移送する場合でも通気用溝を介して通気が可能になり、使用面において有利な容器とすることができる。
【００２６】
請求項３の発明によれば、容器が、平面視において４つの角部を備えたほぼ矩形状に構成され、前記通気用間隙を、少なくとも１つの角部を挟んで２つの辺に渡る状態で形成することによって、角部が海水や水の流動抵抗になるため、通気用間隙を直線状に形成した場合に比べて、入口側連通部を介して通気用間隙内に入り込んだ海水や水が通気用間隙の終端部に移動し難くでき、取扱面において更に有利な容器とすることができる。
【００２７】
請求項４の発明によれば、カバー体の横側面に凹溝部を介して指を接触させることで、カバー体を容易に取り外すことができ、エアポンプのＯＮ−ＯＦＦ操作や電池交換あるいはエアポンプの点検や交換等を工具等を用いることなく容易迅速に行うことができる。しかも、その凹溝部を有効利用することによって形成された隙間を、エアポンプの給排気用の開口に有効利用することができ、構成の簡素化によるコストの低減を図ることができる。
【００２８】
請求項５の発明によれば、通気用間隙が嵌合凸部の頂部表面と前記嵌合凹部の底部表面との間に形成され、通気用間隙を形成する下面が、前記出口側連通部側ほど上方に位置する傾斜面に形成することによって、入口側連通部を介して通気用間隙内に入り込んだ海水や水が入口側連通部側へ移動案内されることから、通気用間隙を形成する下面を水平面に形成したものに比べて、出口側連通部へ移動し難くでき、取扱面において更に有利な容器とすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a seafood container particularly suitable for transporting or storing live fish and shellfish while maintaining the same state.
[0002]
[Prior art]
Conventionally, as the above-mentioned container, for example, the one shown in Japanese Utility Model Laid-Open No. 2-55565 has been proposed. This means that an air pump is housed in a recess formed in the lid, and an air supply pipe for guiding air from the air pump is provided with a predetermined amount of seawater or water through a through hole formed in the bottom of the recess. Air is blown out into the seawater or water from the air blowing part provided at the end of the air supply pipe by introducing it into the container body in which it is put, and the fish and shellfish do not become oxygen-deficient and maintain a live state It can be transported while moving.
[0003]
[Problems to be solved by the invention]
However, since the container contains seawater or water, the container must be hermetically sealed with a lid so that the container does not leak seawater or water. As a result, exhaust gas and the like generated by the respiration of fish and shellfish accumulate on the water surface in the container body and cannot be discharged to the outside. As a result, fresh air cannot be introduced into the container, and Environment was unfavorable for
To solve the above inconvenience, as disclosed in Japanese Patent No. 2939071, a lid for closing an upper end opening of a container is provided with an exhaust port for penetrating in a vertical direction and communicating with the inside of the container to exhaust air. A bottom wall having a through-hole formed therein, and an upper open-type peripheral wall rising upward from the outer peripheral edge of the bottom wall. An air pump is placed on the bottom wall of the lid, and In another lid for closing the upper opening, discharge air from the through hole to the outside or to form a vertical through hole for air guide for supplying fresh external air to the air pump I have.
Since the lid requires another lid for closing the upper end opening, there is an inconvenience that the cost increases due to an increase in the number of parts. In addition, since the vertical through-hole formed in another lid can be easily seen from the outside, the appearance of the container is deteriorated, and the commercial value is disadvantageously reduced.
Further, since the through hole is formed in the lid, there is also a disadvantage that the strength of the lid itself is reduced. Further, the gas in the container is discharged from a discharge port formed in the bottom wall of the lid, and the gas in the container is discharged through the through hole (a hole formed in another lid) common to the air pump and the air is supplied to the air pump. Since it is configured to perform inhalation, there is an inconvenience that good discharge cannot be performed, and there is room for improvement.
[0004]
In view of the above situation, the present invention is intended to solve the problem without losing the appearance, avoiding a decrease in the strength of the lid due to the formation of the through hole, and satisfactorily discharging the gas in the container. Another object of the present invention is to provide a container which can be used.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the container of the present invention comprises a container body having an open top and a lid closing an opening of the container body, and an air supply device is provided to one of the container body and the lid.

The ventilation gap S is located between one long side and one short side adjacent to the long side (between two sides), that is, from a substantially central portion in the circumferential direction of the vertical wall portion 2C with the corner portion K interposed therebetween. Although it is formed over substantially the center in the circumferential direction of the other adjacent vertical wall portion 2D, the formation location and the formation length of the ventilation gap S can be freely changed. The ventilation gap S is formed between the top surface (top surface) of the fitting protrusion 1T and the bottom surface (bottom surface) of the fitting recess 2H, but is located inside the fitting protrusion 1T. The ventilation gap S may be formed by forming a groove recessed from the wall surface of the vertical wall portion or the inner vertical wall portion forming the fitting concave portion 2H facing the vertical wall portion. In such a case, the mold structure for molding the container body 1 and the lid 2 becomes complicated, and there is a disadvantage that the manufacturing cost is increased.
[0018]

However, other configurations may be used. Although not shown in the drawing, as a fixing means for fixing the air blowing portion 3C to the container main body 1, for example, a pair of locking portions projecting upward on the upper surface of the bottom plate portion 1A of the container main body 1 are integrated with the container main body 1. It may be formed and implemented.
[0022]
As shown in FIG. 11, the air pump 3 may be provided in the container body 1 (the lid 2 is omitted in the figure). That is, in order to house the air pump 3, the extension 1G extending in the horizontal direction of the container body 1 is integrally formed with the container body 1, and the space formed by the extension 1G is divided into two parts. The pump body 3A of the air pump 3 is housed in the space 1S. By providing the other space 1W, even if a part of the water or seawater in the container body 1 enters through the notch 1N formed in the container body 1 for inserting the tube 3B into the container body 1, the space 1W It is possible to avoid entering the space 1S on the pump body 3B side only by entering the space. Note that 1M shown in FIG. 11 is a discharge hole for discharging water or seawater that has entered the space 1W or 1S to the outside, but may not be provided.
[0023]
As shown in FIG. 12, the lower surface forming the ventilation gap S, that is, the top surface (upper surface) 1U of the fitting convex portion 1T is located closer to the outlet side communication portion side (the right side in the figure), and the inclined surface (the upper surface). It may be formed on an inclined surface having a predetermined angle X in the drawing). With such an inclined surface, even if water or seawater enters from the inlet-side communicating portion 12, the water or seawater is inclinedly guided to the inlet-side communicating portion 12 side on the inclined surface, so that the outlet is provided. It is possible to prevent reaching to the side communication portion 13. The predetermined angle of the inclined surface may be set to any angle, but there is an advantage that a smaller angle is easier to form.

【The invention's effect】
According to the first aspect of the present invention, a ventilation gap is formed between the joint surfaces of the fitting projections and the fitting recesses originally provided for closing and fixing the container body and the lid, and the ventilation gap is formed. The gas in the container can be satisfactorily discharged to the outside simply by forming an inlet-side communication portion for communicating with the inside of the container and an outlet-side communication portion for communicating with the outside of the container. Moreover, since the ventilation gap is formed in the circumferential direction, even if a part of the seawater or water in the container body enters from the inlet side communication part, the outlet is formed through the circumferentially formed ventilation gap. The container can be guided to the side communication portion and not discharged to the outside or can be reduced to a very small amount, and can be an advantageous container in terms of handling. In addition, since no through hole is formed in the lid, the commercial value can be increased without deteriorating the appearance or reducing the strength of the lid. In addition, by adopting the configuration in which ventilation is performed using the fitting uneven portion as described above, the air supply device that supplies air into the container body can be attached to the lid or any part of the container body. Therefore, the degree of freedom of design that can be attached to any container can be increased.
[0025]
According to the invention of claim 2, a ventilation groove for communicating upward with the outlet side communication portion is formed in the outer wall surface of the lid, so that the outer wall surface is in contact with the horizontal direction. Even when a large number of containers are arranged and stored or transported, ventilation is possible through the ventilation groove, and the container can be made advantageous in terms of use.
[0026]
According to the invention of claim 3, the container is formed in a substantially rectangular shape having four corners in plan view, and the ventilation gap extends over two sides with at least one corner interposed therebetween. By forming, the corners become seawater or water flow resistance, so that seawater or water that has entered the ventilation gap through the inlet-side communication portion is compared to the case where the ventilation gap is formed linearly. It is difficult to move to the terminal end of the ventilation gap, and the container can be more advantageous in terms of handling.
[0027]
According to the fourth aspect of the present invention, the cover body can be easily removed by bringing a finger into contact with the lateral side surface of the cover body via the concave groove portion, so that the air pump can be easily turned on and off, the battery can be replaced, or the air pump can be inspected. And replacement can be easily and quickly performed without using a tool or the like. In addition, the gap formed by effectively utilizing the concave groove can be effectively used as an air supply / exhaust opening of the air pump, and the cost can be reduced by simplifying the configuration.
[0028]
According to the invention of claim 5, the ventilation gap is formed between the top surface of the fitting projection and the bottom surface of the fitting recess, and the lower surface forming the ventilation gap is on the side of the outlet-side communication part. By forming it on the inclined surface located at the upper side, seawater or water that has entered the ventilation gap through the entrance-side communication part is guided to move toward the entrance-side communication part, thereby forming the ventilation gap. As compared with the case where the lower surface is formed in a horizontal plane, the lower surface can be less easily moved to the outlet side communication portion, and the container can be more advantageous in handling surface.
