Description

【0001】
【産業上の利用分野】
本発明は、液状やペースト状の流体物を収納し、吐出口の口元で自動的に開閉される自動開閉装置を有する吐出容器に関する。
【0002】
【従来の技術】
従来、クリームや洗顔料などの化粧品や、歯磨き、シャンプーなどのトイレタリー製品など、液状やペースト状の流体物を収納し、内容物に圧力を加える事により口元で自動的に開口するとともに、消圧により自動的に閉鎖する自動開閉機能を有する吐出口が形成されたチューブ容器やポンプ付き容器であって、吐出口内の流体物を自動的に外気から遮断することにより、吐出口内近傍の流体物を乾燥や劣化から護り、衛生面を配慮した吐出容器が知られている。
【0003】
上記のような自動開閉装置付き容器として、実開平5−62454号公報に開示された吐出容器が提案されている。
【0004】
図7に示すように、前記公報に開示された吐出容器は、容器本体51の頚部52に有頭筒状のキャップ54を外嵌し、このキャップ54の天板部55に、容器本体51の内外に連通するとともに逆止弁56を備えた貫通孔57を設け、この貫通孔57にディップチューブ58を垂設し、前記天板部55の上面に弾性部材からなるドーム59を装着し、このドーム59の裾部の一部と前記キャップ54との間に自閉性を有する開口部60を設けてなるもので、前記ドーム59を押圧することにより、ドーム59とキャップ54との間の開口部60から内容物を吐出する。そして、内容物の吐出後、ドーム59を弾性復帰させると、前記開口部60は自身の自閉機能によって閉じられるというもので、弾性部材を利用した簡単な自動開閉機能を有する開口部60が形成されたポンプ付き吐出容器となっている。
【0005】
【発明が解決しようとする課題】
しかしながら、上記従来の吐出容器は、自動開閉機能を有する開口部60を簡単な構造とすることにより安価に製造できるものではあるが、弾性部材による開口部60自身の弾性力のみで自閉状態を保持する構成であるので、開口部60の密閉性は充分とは言えず、ドーム59や容器本体1の内圧が温度変化により上昇すると、開口部60は自開して内容物が自然に漏洩することがあると言う問題があった。
【0006】
本発明は上記の問題に鑑みてなされたもので、弾性部材を用いた自動開閉装置の口元を確実な閉鎖状態に保持し、構造も簡単で安価な吐出容器にする事を目的としている。
【0007】
【課題を解決するための手段】
そこで、本発明の吐出容器では、胴部に頚部が立設された容器本体と、前記容器本体内に連通する吐出通路が筒体の嘴部の上面に形成され前記頚部に装着された前記筒体の上面に弾性材料で作られた弾性蓋が被覆されて形成され内圧によって開放されるとともに消圧によって自己閉鎖する前記吐出通路に連通した吐出口部を有する吐出栓と、前記容器本体に前記吐出栓を覆って施蓋する平板状の天板の周縁から一体に周壁が垂設された有頭筒状の外蓋と、からなる吐出容器において;前記外蓋がその施蓋時に前記天板の平坦な天面が前記弾性蓋の上面全域に圧接し前記弾性蓋を前記嘴部の上面に弾性的に圧着せしめて前記吐出口部を閉鎖状態に保持することを特徴とすることで、前記課題の解決手段とした。
【0008】
【作用】
本発明に係る吐出容器においては、容器本体内に連通する吐出通路が形成された筒体の上部を弾性部材からなる弾性蓋で被覆することにより、吐出通路に連通し内圧によって開放される自動開閉機能のある吐出口部を有する吐出栓が形成され、前記容器本体に外蓋を被せると、外蓋の内側の押圧部が吐出栓の弾性蓋を筒体に弾性的に圧着し吐出口部を確実に閉鎖する。
【0009】
【実施例】
以下、本発明の実施例を添付図面を参照しながら詳細に説明する。
【0010】
図1は、本発明の吐出容器の第一実施例を示すもので、本実施例の吐出容器は、流体物が収納される容器本体10と、この容器本体10の頚部11に外嵌される蓋状の筒体20と、この筒体20の上面を被覆して吐出栓Tを構成する弾性蓋30と、前記容器本体10の上部に被蓋する外蓋40とから構成されている。
【0011】
前記容器本体10は、ポリエチレン、ポリプロピレンなど軟質の汎用合成樹脂材料を用いて形成され、変形可能な弾性と可撓性を有する胴部12の上面に台部13が形成され、この台部13の上端外周には突条14が周設され、台部13の中央部には、外周に雄螺子15が螺設されているとともに上端に開口部16が開設された頚部11が立設されて、全体としてチューブ状容器に形成されている。
【0012】
前記筒体20は、天板部21の端縁から一体に周壁23が垂設され、この周壁23の内側には前記雄螺子15に螺合する雌螺子22が刻設されて螺子蓋状に形成されている。
【0013】
そして、前記周壁23の下端部には、外周に突起25を有し下端に外向きのフランジ26が周設された径大部24が形成され、前記径大部24の下端内側には、容器本体10の台部13の突条14と脱抜不能に係合される突条27が周設されている。
【0014】
また、天板部21の中央には貫通孔28が穿孔されているとともに、天板部21の上面は片上がりの傾斜面に形成され、この傾斜面の高所側には周壁23から突出した嘴部29が突設され、この嘴部29の上面には前記貫通孔28に連通して容器本体10内に連通する溝状の吐出通路29aが設けられている。
【0015】
また、天板部21の下面にはリブ21aが垂設され、容器本体10の開口部16の内側に嵌合されて容器本体10と筒体21とを液密に保持している。
【0016】
前記弾性蓋30は、ゴムやエラストマーなどの弾性材料を使用して筒体20の上面と相似形に形成され、筒体20の上面を被覆して筒体20とともに吐出栓Tを構成している。そして、この弾性蓋30の下面には、下端に鍔状のフック部31を有する係合突起32が突設され、前記係合突起32は筒体20の貫通孔28に嵌挿され、天板部21の下面にフック部31が掛合して筒体20と脱抜不能に固着されている。
【0017】
また、筒体20の上面を被覆した弾性蓋30は、吐出通路29aの上壁面を形成するとともに、嘴部29の上面に弾性的に密接して吐出通路29aに連通し自動開閉する吐出口部33を形成している。
【0018】
前記外蓋40は、合成樹脂材料や金属材料で形成され、平板状の天板41の周縁から一体に周壁42が垂設されて有頭筒状に形成されている。
【0019】
そして、前記天板41の下面の周縁部には押圧部を形成する突条44が環状に突設されており、この突条44が筒体20の嘴部29の先端部上面に密接した弾性蓋30の上面に圧接して嘴部29の上面に弾性的に圧着することにより吐出口部33の密閉を確実にしている。
【0020】
また、前記周壁42の下端部内側には溝43が周設されて筒体20の径大部24の突起25と係合し、外蓋40の不用意な抜け外れを防止している。
【0021】
以上のように構成された本実施例の吐出容器を使用するときは、外蓋40を取り外し、容器本体10を手指で押圧して充填されている流体物(図示せず)に圧力を加えると、流体物は容器本体10内より貫通孔28、吐出通路29aに押し上げられ、吐出口部33は流体物の自圧によって開口される。また、押圧を中止して消圧されると、吐出口部33は弾性蓋30の弾性復帰力により自己閉鎖される。
【0022】
そして、本実施例の吐出容器を保存するときは、外蓋40を嵌合して外蓋40の溝43と筒体20の径大部20の突起25とを係合させる。すると、外蓋40の突条44が弾性蓋30に圧接し、嘴部29の上面に弾性的に圧着させて吐出口部33を強制的に閉鎖状態にする。
【0023】
従って、保存中に温度変化や容器本体10への不用意な衝撃によって内圧が上昇しても、自圧によって吐出口部33が自開することはなく、不慮の内容物の漏洩による周囲の汚染を防止することができる。
【0024】
しかも、弾性部材を使用した構造の簡単な自動開閉機能を有する吐出口部に、単に外蓋40を嵌合させるだけで密閉を確実に保持する構成であるので、部品が増えることもなく、従って安価に提供することができる。
【0025】
次ぎに、本発明の吐出容器は多様な形態にすることが可能であり、他の実施例について説明する。以下、各図において、上記第一実施例と共通する部分については同一符号を付しその説明を省略する。
【0026】
図2乃至図3は、本発明に係る第二実施例の吐出容器を示すもので、吐出容器がポンプ付き容器である事例を示している。即ち、流体物が収納される容器本体10と、この容器本体10の頚部11に嵌着するポンプ17の排出管18に外嵌される筒体20と、この筒体20の上面を被覆して吐出栓Tを構成する弾性蓋30と容器本体10の上部に被蓋する外蓋40とから構成されている。
【0027】
容器本体10は第一実施例のものとほぼ同様のチューブ状容器であるので、その説明を省略する。尚、本実施例にあっては、容器本体10はチューブ状容器に限るものではなく、瓶状の硬質容器であってもよいことは言うまでもない。
【0028】
また、ポンプ17も極めて周知のものであるので、その詳細な説明は省略する。
【0029】
前記筒体20は、天板21の端縁から一体に周壁23が垂設されているとともに、天板21の中央には貫通孔28が穿設され、前記貫通孔28を囲んで内筒20aが垂設され、前記内筒20aはポンプ17の上面に突出した排出管18に外嵌されている。
【0030】
また、天板21の上面はフラットに形成されているとともに周壁23から嘴部29が突設され、前記嘴部29の上面には貫通孔28に連通しポンプ17の排出管18を介して容器本体10内に連通する溝状の吐出通路29aが設けられている。
【0031】
前記弾性蓋30は第一実施例と同様に、筒体20の上面と相似形に形成され、筒体20の上面を被覆して筒体20とともに吐出栓Tを構成し、吐出通路29aに連通して自動開閉する吐出口部33を形成している。
【0032】
前記外蓋40は、平板状の天板41の周縁から一体に周壁42が垂設されて有頭筒状に形成され、前記天板41の平坦な天面が弾性蓋30の上面全域に圧接し嘴部29の上面に弾性的に圧着させて吐出口部33を閉鎖する押圧部を形成している。
【0033】
以上のように構成された本実施例の吐出容器にあっては、ポンプ17を作動させると、流体物は、容器本体10内よりポンプ17の排出管18、貫通孔28、吐出通路29aを通って吐出口部33を自圧で開放して吐出される。そして、ポンプ17の作動を中止すると、吐出口部33が自閉することは第一実施例と同様である。
【0034】
その他、作用、効果ともに第一実施例と同様であるので、その説明を省略する。
【0035】
図4乃至図5は、本発明に係る第三実施例の吐出容器を示すもので、吐出容器がノズル付き容器である事例を示している。
【0036】
図に示すように、チューブ状の容器本体10の頚部11に螺着された筒体20は、下端にフランジ26を有する周壁23の外周に突起25が周設されているとともに、前記周壁23の天板21の上面には、第二突起25aが周設された径小部23aが一体に設けられ、前記径小部23aの天板21bの上面には、円錐状のノズル23bが突設され、前記ノズル23bには、このノズル23bの側壁から前記天板21bの上面にかけて容器本体10内に連通する吐出通路29aが穿設されている。
【0037】
弾性蓋30は、頂部に貫通孔35が貫設され、下端部の内側には筒体20の第二突起25aと係合する突条36が周設され、全体として弾性体からなる筒状に形成されている。そして、筒体20の上部、即ち、径小部23aからノズル23bの部分を被覆して筒体20とともに吐出栓Tを構成し、吐出通路29aに連通して自動開閉する吐出口部33を形成している。
【0038】
そして、外蓋40の平板状の天板41の下面には環状の内筒45が突設され、前記内筒45が弾性蓋30の先端部に外嵌して圧接し筒体20のノズル23bの上側面に弾性的に圧着させることにより吐出口部33を閉鎖する押圧部を形成している。
【0039】
以上のように構成された本実施例の吐出容器にあっては、容器本体10を押圧すると、流体物は容器本体10内よりノズル23bの吐出通路29aを通って吐出口部33を自圧で開放し、弾性蓋40の頂部の貫通孔35から排出される。
【0040】
そして、押圧を中止すると吐出口部33が自閉すること、および施蓋したときの作用効果は前記各実施例と同様である。
【0041】
図6は、本発明に係る第四実施例の吐出容器を示すもので、ドーム状の弾性蓋と逆止弁37とによるポンプ機能を有する吐出容器の場合の事例を示している。
【0042】
図に示すように、容器本体10の頚部11に螺着された筒体20は、天板21の上面に円盤状の弾性体からなる逆止弁37が嵌め込まれているとともに、周壁23から嘴部29が突設され、前記嘴部29の上面には逆止弁37を介して容器本体10内に連通する溝状の吐出通路29aが設けられている。
【0043】
弾性蓋30は中央部が隆起したドーム状に形成され、筒体20の上面を被覆して筒体20とともにポンプ機能を有する吐出栓Tを構成し、吐出通路29aに連通して自動開閉する吐出口部33を形成している。
【0044】
そして、外蓋40の平板状の天板41の下面には環状の内筒45が垂設され、前記内筒45の先端部が嘴部29の上面に密接した弾性蓋30の上面部分に圧接し嘴部29の上面に弾性的に圧着させることにより吐出口部33を閉鎖する押圧部を形成している。
【0045】
以上のように構成された本実施例の吐出容器にあっては、外蓋40を施蓋するだけで自動開閉機能を有する吐出口部33を口元で確実に閉鎖状態に保持し、ドーム内の内容物の自然漏洩を防止することができる。
【0046】
【発明の効果】
以上説明したように、本発明の吐出容器によれば、吐出通路が形成された筒体の上部を弾性部材からなる弾性蓋で被覆することにより自動開閉機能を有する吐出口部が形成された吐出栓が構成されるとともに、外蓋を施蓋するだけで外蓋内側の押圧部が吐出栓の弾性蓋の外面に圧接して筒体に弾性的に圧着するように構成されているので、吐出口部は口元で開閉されるので衛生的であるとともに、弾性蓋は外蓋のあたかもパッキングのように弾性的に筒体に密着するので、確実に吐出口部の閉鎖状態が保持される。
【0047】
従って、保存中に温度変化や容器本体への不用意な衝撃によって内圧が上昇しても、自圧によって吐出口部が自開することはなく、不慮の内容物の漏洩による周囲の汚染を防止することができる。
【0048】
しかも、弾性部材を使用した構造の簡単な自動開閉機能を有する吐出口部に、単に外蓋を嵌合させるだけで密閉を確実にする構成であるので、部品が増えることもなく、従って安価に提供することができるものである。
