【０００１】
【発明の属する技術分野】
本発明は、遅延噴出装置に関し、特に噴出操作から所定時間経過後に、密閉室内などで容器内容物（例えば殺虫剤や消毒剤など）の噴出動作を開始し、当該開始後はその状態を継続的に保持する遅延噴出装置に関する。
【０００２】
一般に、殺虫剤や消毒剤などを密閉室内などで噴出させるタイプの容器では、利用者の噴出操作時から実際の噴出動作開始時までに所定の時間差を付与してその間に利用者が室外に出れるようにしている。
【０００３】
そして、内容物の遅延噴出機能を付加する際には、利用者の噴出操作時の利便性を確保するとともに、装置自体の構成の簡単化や遅延時間の拡大化を図ること、さらには噴出範囲の広範囲化を図ることが望ましく、本発明はこの要請に応えるものである。
【０００４】
【従来の技術】
図９および図１０は従来の遅延噴出装置（特開平９−１５０８７４号公報）を示す説明図である。図９は遅延噴出装置の静止時を、図１０は遅延噴出装置の作動時をそれぞれ示している。
【０００５】
これらの図において、３１はケ−ス本体，３２はケ−ス本体３１に設置した容器，３３は容器３２を上方向に付勢するコイルスプリング，３４は弁部分（図示省略）を備えたステム，３５はステム３４に嵌合させたノズル，３５ａはノズル下部に立設した複数のリブ，３６はケ−ス本体３１に対する蓋体，３６ａは蓋体３６の上面側に形成した注水用凹部，３６ｂは注水用凹部３６ａに形成した透孔，３６ｃは蓋体３６の上面中央部に形成したノズル挿通孔，３７は容器３２の上端側に嵌着させた支持枠，３８は注水用凹部３６ａと支持枠３７との間に設置した吸水軟化性で筒状の多孔質体をそれぞれ示している。
【０００６】
ステム３４を容器３２に対して押し下げるとその弁部分が閉状態から開状態へと切り替わり、容器３２の内容物がノズル３５の先端部分から外部空間に噴出する。
【０００７】
図９の静止時において、容器３２は、蓋体３６により上面を抑えられた硬質状態の多孔質体３８で押し下げられている。これは、多孔質体３８が常時、すなわち吸水していない状態では保形性を有する硬質なものであるためである。
【０００８】
このとき、容器３２はステム３４といわば一物になった状態でコイルスプリング３３の付勢力に抗して図示のように下動し、ステム３２の弁部分は閉状態のままである。
【０００９】
図１０の作動状態にするには、利用者が図９の静止状態の注水用凹部３６ａに水を注げばよい。
【００１０】
注水用凹部３６ａに注がれた水は透孔３６ｂから下方に移動して多孔質体３８に入りこみ、当該多孔質体を軟化させる。
【００１１】
この軟化の程度が進むにしたがい、コイルスプリング３３の付勢力の方が多孔質体自身の保形力よりも強くなる。そのため、多孔質体３８が蓋体３６方に圧縮されながら、容器３２は当該付勢力で上方に移動していく。
【００１２】
この移動のとき、
▲１▼移動開始から、ノズル３５のリブ３５ａが蓋体３６の裏面部分に当接するまでは、容器３２とステム３４とが互いの相対位置を変えずに一体となって上昇するのでステム３４の弁部分は閉状態のままであり、
▲２▼ノズル３５のリブ３５ａが蓋体３６の裏面部分に当接するとステム３４は停止し、その後は、容器３２および支持枠３７が停止状態のステム３４に対して上昇するため、ステム３４の弁部分は開状態となって容器３２の内容物がノズル３５の先端部分から噴出し、図９の作動状態（噴出継続状態）へと移行する。
【００１３】
図９および図１０の噴射遅延装置では、
・利用者が図９の注水用凹部３６ａに水を注ぎ終わった噴出操作終了時から、
・吸水した多孔質体３８の軟化作用により容器３２やステム３４，ノズル３５が上昇して当該ノズルのリブ３５ａが蓋体３６の裏面部分に当接してその直後に噴出動作を開始するまで、
の時間を遅延させている。
【００１４】
【発明が解決しようとする課題】
従来の遅延噴出装置の場合、利用者は注水用凹部に注ぐための水を用意しなければならないので、遅延噴出操作時の利便性が悪いという問題点があった。
【００１５】
また、内容物の噴出機構としては本来必要でない多孔質体や（内容物を収納した容器自体を持ち上げるための）コイルスプリングなどの構成要素を用いているので、遅延噴出装置を構成する部品点数が増えてコスト高となり、製造・組立て工程も複雑になるなどの問題点があった。
【００１６】
そこで、本発明では、内容物の噴出機構として用いられる構成要素の改良により、容器自体は固定したままで、利用者が噴出機構とは別のものを何ら用意することなしに遅延噴出操作を行なえるようにして、操作時の利便性を向上させるとともに、遅延噴出装置の部品点数の増加や製造・組立て工程の複雑化を抑えることを目的とする。
【００１７】
また、遅延噴出動作用の弁部材の移動を外から見られるようにして、利用者が当該弁部材の噴出操作された位置から噴出動作位置への移行開始を簡単に確認できるようにすることを目的とする。
【００１８】
また、出力側孔部の噴出面を所定角度の傾斜面にして、内容物の噴出エリアの広範囲化を図ることを目的とする。
【００１９】
また、噴出操作終了時から実際の噴出動作開始時までの遅延時間を拡大するための構成要素を付加して、利用者にとってより十分な遅延時間を確保することを目的とする。
【００２０】
【課題を解決するための手段】
本発明はこの課題を次のようにして解決する。
（１）噴出操作から所定時間経過後に容器の内容物の噴出動作を開始し、当該開始後はその動作状態を継続的に保持する遅延噴出装置において、
噴出用の出力側孔部（例えば後述の出力側孔部２ａ）を有し、前記噴出操作により下方向に移動してその後、前記内容物の圧力によって当該出力側孔部の側の部分が後述のカバー部材の開口部分から出てくる動作態様で上方向に移動する弁部材（例えば後述の帽子状部２，筒状垂下部３，鞘状応動部４，筒状応動部２１）と、
前記内容物の収納用空間部（例えば後述の収納用空間部６ｇ，収納空間２２ａ）を有し、前記噴出操作により下方向に移動して所定位置に保持されるとともに、前記弁部材が上方向に移動するときの案内部として作用するカバー部材（例えば後述の内側筒状部６，外側筒状部７，内側筒状部２２）と、
前記カバー部材と一体になって下方向に移動し、容器内部と連通してその状態を継続するステム（例えば後述のステム１０）と、
前記出力側孔部に対する噴出用の弁機構（例えば後述のスカート部４ｃと内側筒状部６の内周面６ａ〜６ｃ、環状弁２１ｂと鞘状棒部２３）と、を有し、
この弁機構を、前記連通状態の前記ステムを介して前記収納用空間部に流入する内容物の圧力で前記弁部材が前記所定位置の前記カバー部材に対して所定長だけ前記動作態様で上方向に移動したときに、それまでの閉状態から開状態へと切り替わって前記容器内部と前記出力側孔部とを連通させる態様のものとする。
（２）上記（１）において、
前記噴出操作により下方向に移動する前記カバー部材の案内部（例えば後述の筒状部１５ａ）を、その上方が開口して外部空間に通じる態様のものとする。
（３）上記（１），（２）において、
前記出力側孔部を、その噴出面（例えば後述の噴出面２ｆ）が水平面に対して所定の傾斜角度を持つ態様のものとする。なお、後述のように、この傾斜角度の望ましい範囲は５〜２０°である。
【００２１】
本発明によれば、上記（１），（２）のように、先ず利用者の噴出操作により弁部材，カバ−部材およびステムを下方向に移動させ、この中のカバ−部材を所定位置に保持してステムと容器内部とを連通状態にし、その後、弁部材がこの停止状態のカバ−部材に対し上方向に移動して新たな弁機構が開状態となることにより内容物が噴出するようにしている。そのため、遅延噴出操作が押圧だけの簡単なものとなって、遅延噴出装置の部品点数の削減や製造・組立て工程の簡単化を図ることができる。
【００２２】
利用者は、噴出用の出力側孔部を持つ弁部材の移動の様子（いったん下方に移動させた弁部材が上動していく様子）から遅延噴出装置が正常動作するであろうと確認することができる。
【００２３】
また、上記（３）のように、出力側孔部の噴出面を例えば５〜２０°の角度を持つ傾斜面にしている。そのため、出力側孔部から噴出する内容物はこの角度でいわば振られることになり、内容物を出力側孔部から真っ直ぐ上方に噴射する場合に比べ、噴射後の沈降粒子によって噴射性能が影響を受けたり床面が濡れたりする程度を減少させることができる。
【００２４】
【発明の実施の形態】

をそれぞれ示している。
【００２７】
被案内用の突状部２ｂおよび係合用の突状部６ｈ，７ｂ，１５ｂ，１５ｃ，１６ａなどを各周面の一周にわたって形成するかどうかや、出力側孔部２ａ，リブ２ｇ，スリット状部７ａの個数をいくらにするかなどは任意である。また、出力側孔部２ａのテーパ状の噴出面２ｆの（水平面に対する）傾斜角度は任意であり、望ましくは５〜２０°である。
【００２８】
本明細書において、「スカ−ト部」は下側の方が上側よりも径方向に広がっている周面を示し、「逆スカ−ト部」は上側の方が下側よりも径方向に広がっている周面を示している。
【００２９】
また、内容物の上流側（容器本体１４の側）を「下」、内容物の下流側（弁部材１の出力側孔部２ａの側）を「上」としている。
【００３０】
ここで、筒状垂下部３および鞘状応動部４はテ−パ状段部３ｂで強く嵌合し、これらと帽子状部２とからなる弁部材１の全体は一体化している。
【００３１】
内側筒状部６およびステム１０はラッパ状部６ｆで強く嵌合し、カバ−部材５（内側筒状部６，外側鞘状部７）とステム１０の全体も一体化している。
【００３２】
弁部材１は、
・帽子状部２の突状部２ｂが内側筒状部６の外周面と例えばその一周にわたって当接し、
・帽子状部２のスカ−ト部２ｄおよび逆スカ−ト部２ｅの各端部が外側鞘状部７の内周面とその一周にわたって密接し（図１，図２の場合）、
・筒状垂下部３のスカ−ト部３ａの端部が内側筒状部６の内周面の大径部分６ａとその一周にわたって密接し、
・鞘状応動部４のスカ−ト部４ｃの端部が内側筒状部６の内周面の小径部分６ｂとその一周にわたって密接している。
【００３３】
カバ−部材５は、外側鞘状部７の突状部７ｂがカバ−体１５の筒状部１５ａの内周面に当接している。
【００３４】
したがって、カバ−部材５（内側筒状部６および外側鞘状部７）は一体となってカバ−体１５の筒状部１５ａに案内されながら上下方向に移動可能である。
【００３５】
また、ステム１０の横孔部１０ｂが開くと、弁部材１（帽子状部２，筒状垂下部３および鞘状応動部４）は鞘状応動部４に流入してくる内容物の圧力を受け、一体となってカバ−部材５に案内されながら上方向に移動する。
【００３６】
容器本体１４に入っている内容物が弁部材１の出力側孔部２ａにいたるまでの経路順序は、概略、
▲１▼ハウジング１２の入力側孔部１２ａ
▲２▼ハウジング１２の内周面とステム１０の外周面との隙間部分
▲３▼ステム１０の横孔部１０ｂ
▲４▼ステム１０の通路１０ａ
▲５▼内側筒状部６の孔部６ｅ
▲６▼内側筒状部６の収納用空間部６ｇ（鞘状応動部４の内部空間４ｅ）
▲７▼鞘状応動部４のスカ−ト部４ｃと内側筒状部６の内周面の大径部分６ａとの隙間部分
▲８▼鞘状応動部４の溝部４ｂ
▲９▼筒状垂下部３の空間部分３ｃ
である。
【００３７】
図１の静止時には、
・ステム１０はコイルスプリング１２ｂの作用により上方向に付勢されて図示の位置で安定し、
・ステムラバ−１１がステム１０の横孔部１０ｂの上流側開口部分を閉塞し、
・外側鞘状部７の突状部７ｂは筒状部１５ａの係合用の突状部１５ｂより上方に位置し、
・弁部材１は、鞘状応動部４の開口側端部４ｄが内側筒状部６の下側段部６ｄに当接した状態（鞘状応動部４のスカ−ト部４ｃが内側筒状部６の内周面の小径部分６ｂと密接し、帽子状部２のスカ−ト部２ｄおよび逆スカ−ト部２ｅの各端部が外側鞘状部７の内周面と密接した状態）となり、
・キャップ１６の突状部１６ａとカバ−体１５の突状部１５ｃとが係合した状態になっている。
【００３８】
このとき、内容物の噴出経路の上記▲３▼および▲７▼の部分が確保されていないので、容器本体１４の中の内容物が弁部材１の出力側孔部２ａまで流れることは勿論ない。
【００３９】
内容物を噴出させるには、利用者がキャップ１６をカバ−体１５から取り外して例えば弁部材１の上面部分（帽子状部２の出力側孔部２ａの周辺部分）を押圧すればよい。なお、キャップ１６およびカバ−体１５は合成樹脂製のものであり、当該取り外し作業は簡単に行なえる。
【００４０】
この押圧操作にともない、
(1) 弁部材１（帽子状部２，筒状垂下部３および鞘状応動部４）およびカバ−部材５（内側筒状部６および外側鞘状部７）が一体となって下方向に移動し、
(2) 内側筒状部６と一体のステム１０も下方向に移動してステムラバ−１１が図２のように変形することにより、ステム１０の横孔部１０ｂの上流側開口部分が開状態になり、
(3) 下方向に移動したカバ−部材５は、外側鞘状部７の突状部７ｂが筒状部１５ａの突状部１５ｂより下方に位置してこれと係合状態となる。なお、外側鞘状部７および筒状部１５ａは合成樹脂製のものであり、突状部７ｂが筒状部１５ａの突状部１５ｂより下方に移動しそこに保持されることは確実に行なわれる。
【００４１】
その結果、内容物噴出経路の上記▲３▼の部分が確保され、内容物はステム１０の通路１０ａおよび内側筒状部６の孔部６ｅを経由して鞘状応動部４の内部空間４ｅに流入していく（図２参照）。
【００４２】
この流入内容物の圧力により、鞘状応動部４は、そのスカ−ト部４ｃの端部が（外側鞘状部７の突状部７ｂと筒状部１５ａの突状部１５ｃとの係合のため、上方向に移動することのない）内側筒状部６の内周面の小径部分６ｂと密接した状態のまま上方向に移動していく。
【００４３】
この移動において、鞘状応動部４のスカ−ト部４ｃと内側筒状部６の小径部分６ｂとの密接状態が続く間は内容物噴出経路の上記▲７▼の部分が確保できないため、鞘状応動部４の内部空間４ｅや内側筒状部６の収納用空間部６ｇ（図３参照）に流入した内容物が鞘状応動部４の溝部４ｂまで進むことはない。
【００４４】
利用者の上記押圧操作から時間が経過し、鞘状応動部４のスカ−ト部４ｃの端部が内側筒状部６の小径部分６ｂから斜面部分６ｃに達するまで移動した時点以降は、上記▲７▼の部分が確保されて、すなわち出力側孔部２ａまでの内容物噴出経路の全体が形成される（図３参照）。
【００４５】
なお、鞘状応動部４の内側筒状部６に対する上方向への移動は、これと連動する帽子状部２の内周面に形成した突状部２ｂが内側筒状部６の突状部６ｈと係合するまで続く（図３参照）。
【００４６】
このように、押圧操作開始時から内容物噴出経路の上記▲７▼の部分が確保されるまでの時間だけ噴出動作を遅延させている。
【００４７】
この遅延時間は、弁部材１の形状，サイズや重さ、弁部材１とカバ−部材５との密接の程度、内側筒状部６の小径部分６ｂの上下方向の長さ、鞘状応動部４の形状やサイズなどを調整して希望値に設定することができる。
【００４８】
内側筒状部６の外周面や外側鞘状部７と、帽子状部２の天井面部分２ｃとの間の空間部分７ｄに、鞘状応動部４の上方向への移動に応じて外気を吸入することで、遅延時間の拡大を図っている。
【００４９】
すなわち、内容物の圧力で持ち上げる対象として、上記▲１▼乃至▲９▼の内容物噴出経路の形成に直接関係する鞘状応動部４および内側筒状部６の他に、外側鞘状部７を付加することにより、遅延噴出動作のためのいわば駆動源ともいえる流入内容物（圧力）が増加するときの抵抗分を大きくして鞘状応動部４の移動速度の低速化を図るものである。
【００５０】
外気の吸入経路は、概略、
外側鞘状部７のスリット状部７ａ−筒状部１５ａの内周面と外側鞘状部７のの外周面との隙間−ブッシュ９の上流側段部９ｂ−ブッシュ９の溝部９ａ−ブッシュ９の下流側段部９ｃ−吸入用部材８の空間部分８ｅ−吸入用部材８の吸入用孔部８ｃである。
【００５１】
なお、外側鞘状部７の筒状部７ｅには吸入用部材８が下方から押し込まれる形で嵌合している。
【００５２】
嵌合状態の吸入用部材８は、その鍔部分８ａが筒状部７ｅの下端部に当接するとともに、その天井部分８ｂが外側鞘状部７の底面（外気用孔部７ｃ）との間に隙間空間７ｈを生成している。
【００５３】
吸入用部材８の中にはブッシュ９が下方から押し込まれる形で嵌合し、ブッシュ９の（下流側段部９ｃに続く）上面部分が吸入用部材８の天井部分８ｂの裏面縁側のベンチ状段部８ｄに当接している。
【００５４】
吸入用部材８の中にブッシュ９を設けることにより、吸入外気中のごみなどが外気吸入用の空間部７ｄに入り込まないようにするとともに、外気の吸入の程度を、例えば単位時間あたりの外気吸入量が少なくなるように調整している。
【００５５】
すなわち、空間部７ｄの圧力の増加率を小さくすることにより、利用者の押圧操作で図２の状態に設定された鞘状応動部４のスカ−ト部４ｃの端部が上昇して図３の噴出動作開始状態となるまでの遅延時間を長くしている。
【００５６】
この調整機能を考慮しない場合などには吸入用部材８の中にフィルタを設けるようにしてもよい。
【００５７】
図３に示すように、鞘状応動部４のスカ−ト部４ｃの端部が内側筒状部６の内周面の小径部分６ｂから大径部分６ａに移行するのと略同じタイミングで、帽子状部２の逆スカ−ト部２ｅの端部も外側鞘状部７の内周面の小径部分７ｇから大径部分７ｆに移行して、当接端部と当接内周面とは非接触状態になる。
【００５８】
これは、弁部材１が噴出動作を開始しようとする際の当該弁部材の（上方向への移動に対する）抵抗分をいくらかでも減らすことにより、内容物噴出経路の上記▲７▼を確保するときの過渡的時間を短縮して内容物の噴出開始動作をシャ−プなものにするためである。
【００５９】
図６および図７は本発明の実施の形態（その２）であり、図６は遅延噴出装置の静止時の状態を示し、図７は遅延噴出装置の作動時の状態を示している。
【００６０】
図６および図７で新たに用いる参照番号は、筒状応動部２１，スカ−ト部２１ａ，ラバ−製の環状弁２１ｂ，下方空間部２１ｃ，カバ−部材５を構成する内側筒状部２２，内容物の収納空間２２ａ，内周面２２ｂ，鞘状棒部２３，鞘状棒部の上端部分（テ−パ面状）２３ａ，横孔部２３ｂである。他の参照番号は図１乃至図５のそれを用いている。
【００６１】
図１乃至図５の遅延噴出装置との相違点は、
・弁部材１を構成する帽子状部２と一体に筒状応動部２１を形成したこと
・筒状応動部２１にスカ−ト部２１ａを形成し、筒状応動部２１の下方空間部２１ｃにラバ−製の環状弁２１ｂを設けたこと
・カバ−部材５を構成する内側筒状部２２（内容物の収納空間２２ａ）の内周面２２ｂを上下方向の全体にわたって略同一径としたこと
・内側筒状部２２に鞘状棒部２３を設け、その上端部分２３ａをテ−パ面状とするとともに、横孔部２３ｂを形成したこと
・環状弁２１ｂと鞘状棒部２３との間で弁作用を行なうこと
・筒状応動部２１のスカ−ト部２１ａの端部はその上下方向の位置にかかわらず内側筒状部２２の内周面２２ｂに密接していること
・内側筒状部２２にステム１０が嵌合していないこと
などである。なお、環状弁２１ｂは弁作用部分に相当し、下方空間部２１ｃは内容物の収納空間２２ａにも相当している。
【００６２】
この遅延噴射装置を用いる場合にも弁部材１の上面部分を押圧すればよく、当該押圧操作にともない、
(11)弁部材１（帽子状部２および筒状応動部２１）とカバ−部材５（内側筒状部２２および外側鞘状部７）が一体となって下方向に移動し、
(12)ステム１０は内側筒状部２２で押し下げられてステムラバ−１１が変形することにより、ステム１０の横孔部１０ｂの上流側開口部分が開状態になり（図２参照）、
(13)カバ−部材５は、外側鞘状部７の突状部７ｂが筒状部１５ａの突状部１５ｃより下方に位置してこれと係合状態となる（図２参照）。
【００６３】
利用者の押圧操作が終了したこの段階では、筒状応動部２１は内側筒状部２２に対して図６の静止時と同じ位置関係にある。このとき、環状弁２１ｂは鞘状棒部２３の外周面に密接している。
【００６４】
その後、筒状応動部２１は、ステム１０−鞘状棒部２３−横孔部２３ｂを経由して下方空間部２１ｃおよび収納空間２２ａに流入する内容物の圧力作用により上方向に移動していく。
【００６５】
そして、筒状応動部２１が図７の位置まで上昇して環状弁２１ｂが鞘状棒部２３の外周面から離れると、内容物はその隙間部分を通って出力側孔部２ａから噴出される。
【００６６】
ここでの遅延時間は、押圧操作の終了時から環状弁２１ｂが上昇して鞘状棒部２３のテ−パ面状の上端部分２３ａの範囲に入り込む時点までの、筒状応動部２１の移動時間である。
【００６７】
図６および図７の遅延噴出装置についてのその他の構成要素や作用などは図１乃至図５のそれと同様である。
【００６８】
図２，図３，図６および図７からも明らかなように、各遅延噴出装置のキャップ１６をカバー体１５から取り外した状態では、弁部材１（帽子状部２）が外部空間に露出している。そのため、利用者は弁部材１の上下動を視覚的に確認することができる。
【００６９】
図８は出力側孔部の噴出面をテーパ状に形成したときの帽子状部などをを示している。
【００７０】
ここで、帽子状部２は１個または２個の出力側孔部２ａを持ち、その噴出面２ｆの（水平面に対する）望ましい傾斜角度は５〜２０°である。
【００７１】
出力側孔部２ａの上流側空間には３個のリブ２ｇを形成している。
各リブ２ｇの内側形成方向は当該上流側空間の中心から同一態様でずれており、このリブの間を通って出力側孔部２ａの噴出面２ｆに進んでいく内容物の流れはいわば螺旋状となる。そして、図示のように、内容物は左側の空間に振られたかたちで広範囲にわたって噴出する。
【００７２】
なお、各リブ２ｇを、出力側孔部２ａの上流側空間の中心に対する放射状方向に形成してもよい。
【００７３】
【発明の効果】
本発明は、このように、先ず利用者の噴出操作により弁部材，カバ−部材およびステムを下方向に移動させ、この中のカバ−部材を所定位置に保持してステムと容器内部とを連通状態にし、その後、弁部材がこの停止状態のカバ−部材に対し上方向に移動して新たな弁機構が開状態となることにより内容物が噴出するようにしているので、遅延噴出操作を押圧だけの簡単なものとし、遅延噴出装置の部品点数の削減や製造・組立て工程の簡単化を図ることができる。
【００７４】
また、噴出操作にともなって弁部材（帽子状部）は外部空間に露出したまま遅延噴出モード位置へと移動していくので、利用者は、この移動の様子を見て、遅延噴出操作が正しく行われたことを視覚的に確認できる。
【００７５】
また、出力側孔部の噴出面を傾斜面にしているので、出力側孔部から噴出する内容物はこの角度でいわば振られることになり、内容物を出力側孔部から真っ直ぐ上方に噴射する場合に比べ、噴射後の沈降粒子によって噴射性能が影響を受けたり床面が濡れたりする程度を減少させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a delayed ejection device, and in particular, after a predetermined time has elapsed since the ejection operation, the container contents (for example, insecticides and disinfectants) are ejected in a sealed chamber or the like, and the state is continuously maintained after the start. It is related with the delay jet apparatus hold | maintained.
[0002]
In general, for containers of the type in which insecticides or disinfectants are ejected in a sealed room, a predetermined time difference is given from the time of the user's ejection operation to the start of the actual ejection operation, during which the user goes out of the room. It is trying to be.
[0003]
In addition, when adding a delayed jetting function of contents, the convenience of the user during the jetting operation is ensured, the configuration of the device itself is simplified and the delay time is extended, and the jetting range is further increased. Therefore, the present invention meets this demand.
[0004]
[Prior art]
9 and 10 are explanatory views showing a conventional delayed ejection device (Japanese Patent Laid-Open No. 9-150874). FIG. 9 shows when the delayed ejection device is stationary, and FIG. 10 shows when the delayed ejection device is in operation.
[0005]
In these figures, 31 is a case body, 32 is a container installed on the case body 31, 33 is a coil spring for urging the container 32 upward, and 34 is a stem having a valve portion (not shown). , 35 is a nozzle fitted to the stem 34, 35 a is a plurality of ribs erected at the lower part of the nozzle, 36 is a lid for the case body 31, 36 a is a water injection recess formed on the upper surface side of the lid 36, 36 b is a through hole formed in the water injection recess 36 a, 36 c is a nozzle insertion hole formed in the center of the upper surface of the lid 36, 37 is a support frame fitted to the upper end side of the container 32, and 38 is a water injection recess 36 a A water-absorbing soft and cylindrical porous body installed between the support frame 37 and the support frame 37 is shown.
[0006]
When the stem 34 is pushed down with respect to the container 32, the valve portion is switched from the closed state to the open state, and the contents of the container 32 are ejected from the tip portion of the nozzle 35 to the external space.
[0007]
9 is stationary, the container 32 is pushed down by the hard porous body 38 whose upper surface is suppressed by the lid body 36. This is because the porous body 38 is a hard material having shape retaining properties at all times, that is, in a state where water is not absorbed.
[0008]
At this time, the container 32 moves downward as shown in the figure against the urging force of the coil spring 33 in a state of being in one piece with the stem 34, and the valve portion of the stem 32 remains closed.
[0009]
In order to achieve the operation state of FIG. 10, the user may pour water into the water injection recess 36a in the stationary state of FIG.
[0010]
The water poured into the water injection recess 36a moves downward from the through hole 36b and enters the porous body 38, thereby softening the porous body.
[0011]
As the degree of softening progresses, the urging force of the coil spring 33 becomes stronger than the shape retaining force of the porous body itself. Therefore, the container 32 moves upward by the urging force while the porous body 38 is compressed toward the lid body 36.
[0012]
During this move,
(1) From the start of movement until the rib 35a of the nozzle 35 comes into contact with the back surface portion of the lid 36, the container 32 and the stem 34 rise together without changing their relative positions. The valve part remains closed,
(2) The stem 34 stops when the rib 35a of the nozzle 35 comes into contact with the back surface portion of the lid 36, and thereafter, the container 32 and the support frame 37 rise with respect to the stopped stem 34. The valve portion is in an open state, and the contents of the container 32 are ejected from the tip portion of the nozzle 35, and the operation state of FIG.
[0013]
In the injection delay device of FIG. 9 and FIG.
-From the end of the ejection operation when the user has finished pouring water into the water injection recess 36a in FIG.
Until the container 32, the stem 34, and the nozzle 35 are lifted by the softening action of the porous body 38 that has absorbed water and the rib 35a of the nozzle comes into contact with the back surface portion of the lid body 36 and immediately after that, the ejection operation starts.
The time is delayed.
[0014]
[Problems to be solved by the invention]
In the case of the conventional delayed jetting device, the user has to prepare water for pouring into the concave portion for pouring water, so that there is a problem that convenience during the delayed jetting operation is poor.
[0015]
In addition, since the content ejection mechanism uses components such as a porous body which is not originally required and a coil spring (for lifting the container containing the content itself), the number of parts constituting the delayed ejection device is small. There were problems such as increased costs and complicated manufacturing and assembly processes.
[0016]
Therefore, in the present invention, by improving the components used as the content ejection mechanism, the container itself can remain fixed, and the user can perform the delayed ejection operation without preparing anything other than the ejection mechanism. Thus, it is intended to improve the convenience during operation and to suppress an increase in the number of parts of the delayed ejection device and a complicated manufacturing / assembling process.
[0017]
Also, the movement of the valve member for the delayed ejection operation can be seen from the outside so that the user can easily confirm the start of the transition from the position where the valve member is ejected to the ejection operation position. Objective.
[0018]
It is another object of the present invention to widen the content ejection area by making the ejection surface of the output side hole portion an inclined surface having a predetermined angle.
[0019]
Another object is to secure a sufficient delay time for the user by adding a component for increasing the delay time from the end of the ejection operation to the actual start of the ejection operation.
[0020]
[Means for Solving the Problems]
The present invention solves this problem as follows.
(1) In the delayed ejection device that starts the ejection operation of the contents of the container after a predetermined time has elapsed from the ejection operation, and continuously maintains the operation state after the start,
It has an output side hole for ejection (for example, an output side hole 2a described later), and moves downward by the ejection operation, and then the pressure of the contents causes the output side hole ~ side Is a valve member (for example, a cap-like portion 2, a cylindrical hanging portion 3, a sheath-like responding portion 4, and a cylindrical responding portion 21 which will be described later). )When,
It has a storage space for the contents (for example, a storage space 6g and a storage space 22a, which will be described later), moves downward by the ejection operation and is held at a predetermined position, and the valve member is upward. A cover member (for example, an inner cylindrical portion 6, an outer cylindrical portion 7, an inner cylindrical portion 22 described later) that acts as a guide portion when moving to
A stem (for example, stem 10 to be described later) that moves downward integrally with the cover member, communicates with the inside of the container, and continues its state;
A valve mechanism for ejection with respect to the output side hole (e.g., a skirt portion 4c described later and inner peripheral surfaces 6a to 6c of the inner cylindrical portion 6, an annular valve 21b and a sheath-like rod portion 23),
The valve mechanism is moved upward in the operation mode by a predetermined length with respect to the cover member at the predetermined position by the pressure of the contents flowing into the storage space through the stem in the communication state. When it moves to, it will be the thing of the aspect which switches from the closed state until then to an open state, and connects the said container inside and the said output side hole part.
(2) In (1) above,
A guide portion (for example, a cylindrical portion 15a to be described later) of the cover member that moves downward by the ejection operation is configured to open to the outside and to communicate with the external space.
(3) In the above (1) and (2),
The output side hole is configured such that its ejection surface (for example, later-described ejection surface 2f) has a predetermined inclination angle with respect to the horizontal plane. As will be described later, the desirable range of this inclination angle is 5 to 20 °.
[0021]
According to the present invention, as in the above (1) and (2), first, the valve member, the cover member, and the stem are moved downward by the user's ejection operation, and the cover member therein is moved to a predetermined position. The stem is in communication with the inside of the container, and then the valve member moves upward with respect to the cover member in the stopped state, and the new valve mechanism is opened so that the contents are ejected. I have to. For this reason, the delayed ejection operation can be performed simply by pressing, and the number of parts of the delayed ejection device can be reduced and the manufacturing and assembling process can be simplified.
[0022]
The user should confirm that the delayed ejection device will operate normally from the state of movement of the valve member having the output side hole for ejection (the state in which the valve member once moved downward moves upward). Can do.
[0023]
Further, as described in (3) above, the ejection surface of the output side hole is an inclined surface having an angle of, for example, 5 to 20 °. Therefore, the content ejected from the output side hole is shaken at this angle, and the injection performance is affected by the settled particles after the injection, compared to the case where the content is ejected straight up from the output side hole. It is possible to reduce the degree of receiving and getting the floor wet.

At this time, since the portions {circle around (3)} and {circle around (7)} of the content ejection path are not secured, the content in the container body 14 does not flow to the output side hole 2a of the valve member 1 as a matter of course. .
[0039]
In order to eject the contents, the user may remove the cap 16 from the cover body 15 and press, for example, the upper surface portion of the valve member 1 (the peripheral portion of the output side hole portion 2a of the hat-like portion 2). The cap 16 and the cover body 15 are made of synthetic resin, and the removal operation can be easily performed.
[0040]
With this pressing operation,
(1) The valve member 1 (the cap-shaped portion 2, the tubular hanging portion 3 and the sheath-like responding portion 4) and the cover member 5 (the inner tubular portion 6 and the outer sheath-like portion 7) are integrated downward. Move and
(2) The stem 10 integrated with the inner cylindrical portion 6 is also moved downward, and the stem rubber 11 is deformed as shown in FIG. 2, so that the upstream opening portion of the lateral hole portion 10b of the stem 10 is opened. Become
(3) In the cover member 5 moved downward, the protruding portion 7b of the outer sheath-like portion 7 is positioned below the protruding portion 15b of the cylindrical portion 15a and is engaged therewith. The outer sheath portion 7 and the cylindrical portion 15a are made of synthetic resin, and it is ensured that the protruding portion 7b moves below the protruding portion 15b of the cylindrical portion 15a and is held there. It is.
[0041]
As a result, the above portion (3) of the content ejection path is secured, and the content enters the internal space 4e of the sheath-like responding portion 4 via the passage 10a of the stem 10 and the hole 6e of the inner cylindrical portion 6. It flows in (see FIG. 2).
[0042]
Due to the pressure of the inflowing contents, the sheath-like responding portion 4 has an end portion of the skirt portion 4c (engaged between the protruding portion 7b of the outer sheath-like portion 7 and the protruding portion 15c of the cylindrical portion 15a. Therefore, it does not move upward) and moves upward while keeping close contact with the small diameter portion 6b of the inner peripheral surface of the inner cylindrical portion 6.
[0043]
In this movement, while the close state between the skat portion 4c of the sheath-like responding portion 4 and the small-diameter portion 6b of the inner cylindrical portion 6 continues, the portion (7) of the content ejection path cannot be secured. The contents that have flowed into the internal space 4 e of the cylindrical reaction portion 4 and the storage space 6 g (see FIG. 3) of the inner cylindrical portion 6 do not advance to the groove 4 b of the sheath-like response portion 4.
[0044]
After the time has elapsed since the above pressing operation by the user and the end portion of the skirt portion 4c of the sheath-like responding portion 4 has moved from the small-diameter portion 6b of the inner cylindrical portion 6 to the inclined portion 6c, The portion {circle around (7)} is secured, that is, the entire content ejection path to the output side hole 2a is formed (see FIG. 3).
[0045]
The upward movement of the sheath-like responding portion 4 relative to the inner cylindrical portion 6 is caused by the protruding portion 2b formed on the inner peripheral surface of the hat-like portion 2 interlocking with the inner cylindrical portion 6 being the protruding portion of the inner cylindrical portion 6. It continues until it engages with 6h (see FIG. 3).
[0046]
Thus, the ejection operation is delayed by the time from the start of the pressing operation until the portion (7) of the content ejection path is secured.
[0047]
This delay time includes the shape, size and weight of the valve member 1, the degree of close contact between the valve member 1 and the cover member 5, the vertical length of the small diameter portion 6 b of the inner cylindrical portion 6, and the sheath-like responding portion. The shape and size of 4 can be adjusted and set to desired values.
[0048]
The outside air is applied to the space portion 7d between the outer peripheral surface of the inner cylindrical portion 6 or the outer sheath-like portion 7 and the ceiling surface portion 2c of the hat-like portion 2 in accordance with the upward movement of the sheath-like responding portion 4. By inhaling, the delay time is extended.
[0049]
That is, as an object to be lifted by the pressure of the contents, in addition to the sheath-like responding part 4 and the inner cylindrical part 6 directly related to the formation of the contents ejection path of the above (1) to (9), the outer sheath-like part 7 Is added to increase the resistance when the inflow contents (pressure), which can be said to be a driving source for the delayed ejection operation, are increased, and the moving speed of the sheath-like responding portion 4 is reduced. .
[0050]
The outside air intake route is roughly
Slit-like portion 7a of outer sheath-like portion 7−Gap between inner peripheral surface of cylindrical portion 15a and outer peripheral surface of outer-shell-like portion 7−Upstream side step portion 9b of bush 9−Groove portion 9a of bush 9—Bush 9 A downstream step portion 9c of the suction member 8, a space portion 8e of the suction member 8, and a suction hole portion 8c of the suction member 8.
[0051]
The inhalation member 8 is fitted into the tubular portion 7e of the outer sheath portion 7 so as to be pushed in from below.
[0052]
The inhalation member 8 in the fitted state has its flange portion 8a in contact with the lower end portion of the cylindrical portion 7e and its ceiling portion 8b between the bottom surface of the outer sheath portion 7 (outside air hole portion 7c). A gap space 7h is generated.
[0053]
A bush 9 is fitted into the suction member 8 so as to be pushed in from below, and the upper surface portion (following the downstream side step portion 9 c) of the bush 9 is bench-shaped on the rear edge side of the ceiling portion 8 b of the suction member 8. It abuts on the step 8d.
[0054]
By providing the bush 9 in the inhalation member 8, dust and the like in the inhaled outside air are prevented from entering the space portion 7 d for inhaling the outside air, and the degree of inhalation of the outside air is determined by, for example, the outside air inhalation per unit time The amount is adjusted to be small.
[0055]
That is, by decreasing the increasing rate of the pressure in the space portion 7d, the end of the skate portion 4c of the sheath-like responding portion 4 set in the state of FIG. The delay time until the squirting operation start state is increased.
[0056]
If this adjustment function is not considered, a filter may be provided in the inhalation member 8.
[0057]
As shown in FIG. 3, at substantially the same timing as the end portion of the skirt portion 4c of the sheath-like responding portion 4 shifts from the small diameter portion 6b of the inner peripheral surface of the inner cylindrical portion 6 to the large diameter portion 6a. The end portion of the reverse skirt portion 2e of the cap-shaped portion 2 also shifts from the small diameter portion 7g to the large diameter portion 7f on the inner peripheral surface of the outer sheath-shaped portion 7, and the contact end portion and the contact inner peripheral surface are defined as follows. It becomes a non-contact state.
[0058]
This is because, when the valve member 1 tries to start the ejection operation, the resistance of the valve member (to the upward movement) is reduced to some extent, thereby securing the above-described (7) of the content ejection path. This is for shortening the transition time of the content and making the content ejection start operation sharp.
[0059]
6 and 7 show an embodiment (part 2) of the present invention. FIG. 6 shows the state of the delayed ejection device when it is stationary, and FIG. 7 shows the state when the delayed ejection device is in operation.
[0060]
The reference numbers newly used in FIGS. 6 and 7 are the cylindrical responding portion 21, the skirt portion 21 a, the rubber-made annular valve 21 b, the lower space portion 21 c, and the inner cylindrical portion 22 constituting the cover member 5. , A content storage space 22a, an inner peripheral surface 22b, a sheath-like bar portion 23, an upper end portion (taper-like shape) 23a of the sheath-like rod portion, and a lateral hole portion 23b. Other reference numerals are those of FIGS. 1 to 5.
[0061]
The difference from the delayed ejection device of FIGS. 1 to 5 is that
-The cylindrical responding portion 21 is formed integrally with the cap-shaped portion 2 constituting the valve member 1.
The skat part 21a is formed in the cylindrical reaction part 21, and the rubber-made annular valve 21b is provided in the lower space part 21c of the cylindrical reaction part 21.
The inner peripheral surface 22b of the inner cylindrical portion 22 (content storage space 22a) constituting the cover member 5 has a substantially same diameter throughout the entire vertical direction.
-The inner cylindrical portion 22 is provided with a sheath-like rod portion 23, the upper end portion 23a of the taper surface is formed, and the lateral hole portion 23b is formed.
-Performing valve action between the annular valve 21b and the sheath-like rod part 23
-The end portion of the skirt portion 21a of the cylindrical responding portion 21 is in close contact with the inner peripheral surface 22b of the inner cylindrical portion 22 regardless of its vertical position.
-The stem 10 is not fitted to the inner cylindrical portion 22
Etc. The annular valve 21b corresponds to a valve action portion, and the lower space portion 21c also corresponds to a content storage space 22a.
[0062]
Even when this delayed injection device is used, the upper surface portion of the valve member 1 may be pressed.
(11) The valve member 1 (the cap-like portion 2 and the tubular responding portion 21) and the cover member 5 (the inner tubular portion 22 and the outer sheath-like portion 7) move together and move downward,
(12) When the stem 10 is pushed down by the inner cylindrical portion 22 and the stem rubber 11 is deformed, the upstream opening portion of the lateral hole portion 10b of the stem 10 is opened (see FIG. 2).
(13) In the cover member 5, the projecting portion 7b of the outer sheath-like portion 7 is positioned below the projecting portion 15c of the cylindrical portion 15a and is engaged therewith (see FIG. 2).
[0063]
At this stage when the user's pressing operation is completed, the cylindrical responding portion 21 is in the same positional relationship with the inner cylindrical portion 22 as in the stationary state of FIG. At this time, the annular valve 21 b is in close contact with the outer peripheral surface of the sheath-like rod portion 23.
[0064]
Thereafter, the cylindrical responding portion 21 moves upward by the pressure action of the contents flowing into the lower space portion 21c and the storage space 22a via the stem 10-sheath-like rod portion 23-lateral hole portion 23b. .
[0065]
Then, when the cylindrical responding portion 21 rises to the position shown in FIG. 7 and the annular valve 21b moves away from the outer peripheral surface of the sheath-like rod portion 23, the contents are ejected from the output side hole portion 2a through the gap portion. .
[0066]
The delay time here is the movement of the cylindrical responding portion 21 from the end of the pressing operation until the annular valve 21b rises and enters the range of the upper end portion 23a of the taper surface of the sheath-like rod portion 23. It's time.
[0067]
The other components and operations of the delayed ejection device of FIGS. 6 and 7 are the same as those of FIGS.
[0068]
As is apparent from FIGS. 2, 3, 6 and 7, the valve member 1 (cap-shaped portion 2) is exposed to the external space when the cap 16 of each delayed ejection device is removed from the cover body 15. ing. Therefore, the user can visually confirm the vertical movement of the valve member 1.
[0069]
FIG. 8 shows a hat-like portion when the ejection surface of the output side hole is formed in a tapered shape.
[0070]
Here, the cap-shaped portion 2 has one or two output side holes 2a, and a desirable inclination angle (relative to the horizontal plane) of the ejection surface 2f is 5 to 20 °.
[0071]
Three ribs 2g are formed in the upstream space of the output side hole 2a.
The inner formation direction of each rib 2g is shifted in the same manner from the center of the upstream space, and the flow of contents passing through the ribs to the ejection surface 2f of the output side hole 2a is a spiral shape. It becomes. Then, as shown in the figure, the contents erupt over a wide area in the form of being swung to the left space.
[0072]
In addition, you may form each rib 2g in the radial direction with respect to the center of the upstream space of the output side hole 2a.
[0073]
【The invention's effect】
In this way, the present invention first moves the valve member, the cover member, and the stem downward by the user's ejection operation, and holds the cover member in a predetermined position so that the stem communicates with the inside of the container. After that, the valve member moves upward with respect to the stopped cover member, and the new valve mechanism is opened, so that the contents are ejected. Therefore, it is possible to reduce the number of parts of the delayed jetting device and simplify the manufacturing / assembling process.
[0074]
In addition, the valve member (cap-shaped part) moves to the delayed ejection mode position while being exposed to the external space along with the ejection operation, so that the user sees this movement and the delayed ejection operation is correct. You can see what happened visually.
[0075]
Moreover, since the ejection surface of the output side hole is inclined, the contents ejected from the output side hole are shaken at this angle, and the contents are ejected straight upward from the output side hole. Compared to the case, it is possible to reduce the degree to which the jetting performance is affected or the floor surface gets wet by the precipitated particles after jetting.
