Description

【０００１】
【産業上の利用分野】
本発明はジュースやビール等の飲み物に使用されるプルトップ缶のような液体容器における液体排出装置に関し、特には、ジュースやビール等の液体容器内の液体を排出し易くして、液体容器内に残留する液体による周囲の汚染、または液体容器の洗浄等の後処理を容易にした液体容器における液体排出装置に関する。
【０００２】
【従来の技術】
ジュース等の飲み物用としては、図１に示す缶１の蓋２の上面に設けられた取手３を手で持ち上げて取り外し片４を切り取り、図２示すように開口部５を形成することのできるプルトップ部６を設けたプルトップ缶が多く用いられ、飲む際には開口部５に直接口を付けてのむ場合が多い。
【０００３】
これに対して実開昭６４−４２２４４ではプルトップ缶の内部にストローを収納し、開口部を取り外すときにストローを取り出して分離し、ストローで飲むことのできる構造を提案している。
【０００４】
【発明が解決しようとする課題】
しかしながら上記の構成においては、開口部を安定して開口させるために図１に示すように取り外し片４の先端部７は蓋２の外周部から所定の距離ｓだけ離す必要がある。
そのため開口部５に直接口を付けて飲む場合、図１０の開口部５の断面図に示すように、最後に開口部５の先端部７と缶１の内壁面８との間にジュース等の飲み物ｐが残留する。
そのために缶を廃棄したときにジュース等の飲み物ｐが徐々に外部に排出されて周囲を汚す原因となると共に、缶のリサイクルにあたって残留物の処理が必要となり不都合である。
【０００５】
また実開昭６４−４２２４４ではストローで飲むため、飲み物が残留する恐れは少ないが、プルトップ缶の内部にストローを収納する構造が複雑であり、コストが嵩むという問題がある。
【０００６】
本発明は上記の問題点に着目してなされたもので、液体容器内の液体を完全に排出可能にして、例えばジュース等の飲んだ後の残留物が少なく、構造簡単でコストの安い液体容器における液体排出装置を提供することを目的としている。
【０００７】
【課題を解決するための手段】
上記の目的を達成するために、本発明に係る液体容器における液体排出装置は、内壁面に隅部を有すると共に、壁面の一部に開口部を形成した液体容器において、前記隅部またはその近傍と開口部とを接続する連通路を設けて構成した。
前記連通路はパイプ状に形成されてもよく、連通路に沿って所定の間隔で相対して設けられた堰により形成されるてもよい。
また、前記液体容器はプルトップ缶であり、壁面の一部に形成した開口部はプルトップ缶の蓋部に設置された飲口とすることができ、前記液体容器は金属性材料で作成され、やはり金属性材料で作成された連通路部材を前記液体容器にかしめにより固着することがてきる。
【０００８】
【作用】
上記のような構成としたため、内壁面に隅部を有すると共に、壁面の一部に開口部を形成した液体容器において、開口部から液体を排出するときに、隅部に溜まった残留液体は開口部と接続された連通路から排出され易くなる。
前記連通路をパイプ状に形成して、その連通路を開口部から吸引することにより、隅部に溜まった残留液体は連通路からほぼ完全に排出される。前記連通路をその連通路に沿って所定の間隔で相対して設けられた堰により形成すれば、隅部に溜まった残留液体は連通路を経由して開口部に排出され易くなる。
また、前記液体容器がジュースやビール等を入れるプルトップ缶であれば、そのプルトップ缶の蓋部に設置された飲口を吸い込むことにより、プルトップ缶内の残留物をほぼ完全に吸い出すことができる。
前記液体容器および連通路部材が金属性材料で作成されていれば、連通路部材を液体容器にかしめにより固着することにより、液体容器の製造コスト低減を図ることができる。
【０００９】
【実施例】
以下に、本発明に係る液体容器における液体排出装置の実施例について、図面を参照して詳述する。
【００１０】
図３は本発明に係る液体容器における液体排出装置の第１実施例を示す、蓋２の飲口５を内側から見た内面図であり、図４は正面図で図３のＡ−Ａ断面図であり、図５は図３のＢ−Ｂ断面で飲口５部分の側面断面図である。
すなわち中央部に飲口５の先端部７と缶１の内壁面８の近傍との間を接続する連通路１０をパイプ状に形成した取付片１１が、その両翼部を蓋２の内面にかしめ部１２、１２により固着されている。
なお、取付片１１の固着方法はかしめではなく接着材により接着してもよい。
【００１１】
図６のように飲口５に直接口を付けて飲んだ場合、飲み物が少なくなった状態で吸うと連通路１０の吸い口に近いａ部の圧力は低下するのでｂ部の液体は吸い出され、ｂ部には殆ど飲み物が残留することはない。
【００１２】
図７は本発明に係る液体容器における液体排出装置の第２実施例を示す、蓋２の内面図であり、図８は図７のＣ−Ｃ断面を示す正面断面図であり、図９は図７のＤ−Ｄ断面である飲口５の側面断面図である。
蓋２の内面には、飲口５と内壁面８の近傍との間を接続する連通路２０を形成する堰２１および堰２２が、所定の間隔ｅを保ってそれぞれかしめ部２３により固着されている。
なお、堰２１および堰２２が金属性の材料でなければ、堰２１および堰２２の固着方法は接着であってもよい。
以上のように第２実施例の構成によれば、飲口５に直接口を付けて飲んだ場合、飲み物が少なくなった状態で吸っても連通路２０はパイプ状ではないため、残留する液体を吸い出し難いが、堰２１および堰２２間ｅに存在する液体が缶１の円周方向に移動することなく飲口５方向に移動するため飲み残しなく飲み込むことができる。
前記第１実施例および第２実施例では、液体容器における液体排出装置をジュースやビール等のプルトップ缶について説明したが、飲料に限らずドラム缶から油類を排出する場合等についても適用することができる。
【００１３】
【発明の効果】
本発明は上記のような構成としたため次のような顕著な効果を奏する。
（１）液体容器内の隅部に残留した液体は連通口を介して開口部に排出され易くなる。
（２）連通路を所定の間隔で相対して設けられた堰により形成しても、液体容器内の隅部に残った液体を排出し易くなるが、特に、連通路をパイプ状に形成して開口部を吸引することにより、液体容器内の隅部に残った液体を完全に排出し易くなる。
（３）本発明をビールやジュース等の飲料のプルトップ缶に適用すれば、プルトップ缶内の飲み物を完全に飲み干すことができるようなる。
（４）そのためプルトップ缶が廃棄されたときに周囲を汚すことはなく、缶のリサイクル時に残留物の処理が容易となる。
（５）また、連通口は液体容器内にかしめ、または接着等により簡単に形成できるため、構造簡単でコストの安い液体容器における液体排出装置を得ることができる。
