Description

【０００１】
【発明の利用分野】
本発明は、化粧液など各種液体に使用可能な液体定量注出容器に関する。尚、本明細書において「液体」というときはクリーム状物などの液状物質を含むものとする。
【０００２】
【従来の技術】
下記の特許文献１に係る容器は、容器体口頸部外面から起立する連通筒の上部外面へ、漏斗形の吐出部材下半の脚筒を螺合させるとともに、上記連通筒上下方向中間部を蛇腹とし、かつ上記脚筒外面に係合凹溝を周設して、該係合凹溝上端部内へ、上記連通筒下部外面から起立するガイド筒上端内面に付した環状突部を、上下動自在に係止しており、吐出部材を上限位置まで螺昇させた後に容器を上下反転させ、吐出部材の先端開口部を掌に当てて正立時における下限位置まで押し込むと、一定量の液体が押し出されるように構成している。
【０００３】

【０００４】
【発明の解決しようとする課題】
例えば整髪料などの化粧料は、個人の嗜好やその日の天候などにより使用量を加減したい場合があり、従って計量の目標値を調節できることが望ましい。
【０００５】
上記従来容器でも吐出部材の螺昇をその上限位置に至る前に停めることで使用量を加減できるが、吐出部材はその中心軸に対して略回転対称な形なので、該部材を何回転させたのかを数えるのが難しい。
【０００６】
上記吐出部材に代えてノズル付き押圧ヘッドを上記連通筒部材の上部外面へ螺合させると、指で触れるノズルの位置から押圧ヘッドの凡その回転数が判るが、それでも尚不便な点がある。例えば押圧ヘッド付き容器は、ノズル孔の開口方向を前方とすると容器体後壁を掌に当てて把持するのが通常であるが、押圧ヘッドの回転によりノズル孔の向きが容器前方からずれると目的面へ正しく液体を注出することができない。これを防止するため、利用者は結局ノズル孔の位置を目視により確認しなければならず、多忙の際には大変煩わしい。
【０００７】
本発明は、容器体口頸部から起立した蛇腹付き連通筒部材の上部外面にノズル付き押圧ヘッドを螺合させ、かつ該押圧ヘッドの昇降を案内するガイド筒を設けた計量液体注出容器を提供すること、及び該計量液体注出容器において、押圧ヘッドとガイド筒とに押圧ヘッド位置決め用の嵌合凹部及び嵌合凸部を設けて、簡単な操作で使用できるようにし、併せて押圧ヘッドの昇降を円滑化して使い勝手を改善することを目的とする。
【０００８】
【課題を解決するための手段】
第１の手段は、口頸部４を起立する容器体１と、
上記口頸部４外面へ嵌合させた装着筒部１２上端から蛇腹部１５を介して上半部１６ｃ小径の注出筒１６を立設した連通筒部材１１と、

第４の手段は、上記第３の手段を有し、かつ上記嵌合凸部２５を、上記係合凹溝底面３８ａ乃至突条２３内周面に周方向へ等間隔に離間させて複数個設けている。
【００１２】
【発明の実施の形態】
本発明に係る実施形態に係る液体定量容器は、容器体１と、連通筒部材１１と、ガイド部材２１と、押圧ヘッド３１と、キャップ４１とで構成している。尚、該キャップは省略することができる。
【００１３】
まず本発明の構成のうち、従来公知の技術と基本的に共通する部分について説明する。
【００１４】
容器体１は、胴部２から肩部３を介して口頸部４を起立している。
【００１５】
連通筒部材１１は、上記口頸部４外面へ嵌合させた装着筒部１２上端から内向きフランジ１３を介して口頸部４上半部内面へ嵌合させたシール筒１４を垂下し、かつ上記内向きフランジ１３の上面内周部から蛇腹部１５を介して注出筒１６を起立している。図示の装着筒部１２は上半部分を小外径に形成している。又、上記内向きフランジ１３の上面外周部前後両側に第１回り止め板部１７を、又、蛇腹部１５の上端部分前後両外面に第２回り止め板部１８をそれぞれ付設している。
【００１６】
上記注出筒１６は、上記蛇腹部１５上端から、外面に螺条を形成した下半部１６ａを起立するとともに、該下半部上端から内向きフランジ１６ｂを介して小径の上半部１６ｃを立設している。又、注出筒上半部１６ｃの内方には、該内面から突出した複数の連結片１６ｄにより栓部１６ｅが支持されている。
【００１７】
ガイド部材２１は、上記装着筒部１２上半部分外面に下部を嵌着させて起立したガイド筒２２を有し、該ガイド筒上部で後述の押圧ヘッド外周壁の下部を囲むとともに、ガイド筒上端部の内面に突条２３を周設している。上記ガイド筒２２の上下方向中間部の内面前後には、それぞれ縦溝２４，２４を縦設しており、これら両縦溝下端部内には上記連通筒部材１１の第１回り止め板１７，１７をそれぞれ嵌着させるとともに、両縦溝の上端部内に上記第２回り止め板部１８，１８をそれぞれ昇降自在に嵌合させている。
【００１８】
本発明において、押圧ヘッド３１は、ヘッド頂壁３３の裏面中央部から内外２重筒状に短尺の栓筒３６及び長尺の連結筒３７を、かつヘッド頂壁３３の周縁部から上記連結筒３７よりも更に長い外周壁３４をそれぞれ垂下するとともに、該外周壁の上部前壁からノズル３２を前方突出し、該ノズルのノズル孔３２ａを上記連結筒３７上端部を貫通して栓筒３６上端部内へ連通させている。そして、押圧ヘッド３１は、上記連結筒３７を上記注出筒上半部１６ｃ外面へ摺動自在に嵌合させるとともに、押圧ヘッド外周壁３４の下部を注出筒下半部１６ｃへ螺合させることで連結筒部材１１に取付けられており、又、図１に示す如く押圧ヘッドの栓筒３６の筒孔下面を上記注出筒の栓部１６ｅで閉塞している。
【００１９】
上記押圧ヘッドの外周壁３４の下部外面には係合凹溝３８を周設する。該係合凹溝は、押圧ヘッド３１の摺動代として一定の上下巾を有しており、又、該係合凹溝の底面３８ａのうち後面部分には図３に示す如く溝状の嵌合凹部３９を縦設する。図示の嵌合凹部は、相互に隣合う左右１対の縦リブの間に形成されている。
【００２０】
更に、本発明においては、ガイド部材２１は、ガイド筒上端の突条２３を、上記押圧ヘッドの係合凹溝３８上端部内に、押圧ヘッドの上下動が自在に係止するとともに、該突条２３内周面の前後対称位置に図３に示す如く等寸の嵌合凸部２５，２５をそれぞれ付設して、そのうち後方側嵌合凸部２５を上記嵌合凹部３９内へ嵌合させている。尚、上記両嵌合凸部のうち一方は省略しても良く、又、係合凹溝の底面３８ａに、周方向へ等間隔に３つ以上の嵌合凸部を形成しても良い。
【００２１】
尚、上記図示例とは逆に、上記押圧ヘッド外周壁３４の下部外面に縦リブ状の嵌合凸部２５を、かつ、上記ガイド筒上端の突条２３内周面に嵌合凹部２５を形成しても良い。
【００２２】
キャップ４１は、キャップ周壁４２の下端部を上記連通筒部材の装着筒部１２下半に嵌着させており、又、キャップ周壁４２の内面に押圧ヘッドのノズル３２先端面を液密に閉塞している。
【００２３】
上記各部材は、それぞれ合成樹脂材で形成することができる。
【００２４】
以上の構成において、図１の状態からキャップ４１を除去し、押圧ヘッド３１を回動させると、該押圧ヘッドが注出筒下半部１６ａに対して図４の如く螺昇するので、栓筒３６下端が栓部１６ｅから上方へ離れる。押圧ヘッド３１の回動により嵌合凹部３９が嵌合凸部２５から離脱し、以下、前後１対の嵌合凸部２５に対して順次嵌合及び離脱を繰り返し、押圧ヘッドを半回転させる度に利用者にクリック感を生じさせるので、該クリック感により押圧ヘッド及びノズル孔の位置決めを行なうことができる。
【００２５】
押圧ヘッド３１を所望位置まで上昇させたのち、図５のように容器を倒立させて押圧ヘッド３１を押圧すると、蛇腹部１５が圧縮されて、注出筒下半部１６ａに対する押圧ヘッド３１の上昇距離ｈに対応する量の容器内液体が吐出される。次に押圧ヘッド３１の押圧を解除すると、蛇腹部１５が弾性復元して外気が容器内へ導入される。
【００２６】
次に押圧ヘッド３１を螺降させると、栓部１６ｅが栓筒３６下端面を閉塞する。
【００２７】
【発明の効果】
本発明は如上の構成であり、請求項１記載の発明によれば、上記連通筒部材１１の上部外面へノズル３２付きの押圧ヘッド３１の外周壁３４を螺合させたから、該押圧ヘッドを回動させながら、ノズル３２の位置により、押圧ヘッド３１を回した凡その回数を知ることができ、例えば連通筒部材外面の一部に計量目盛りを設けた場合のように、目盛りを読むために押圧ヘッドを回す作業を止める必要がないので、迅速な操作が可能となる。
【００２８】
請求項２の発明によれば次の効果を奏する。
○押圧ヘッド外周壁３４に周設した係合凹溝３８の上部内へガイド筒２２上端の突条２３を昇降自在に係止させるとともに、上記係合凹溝の底面３８ａと上記突条２３の内周面との一方に押圧ヘッド位置決め用の嵌合凹部３９を、他方に該嵌合凹部と係合可能な嵌合凸部２５をそれぞれ形成したから、触感により、即ち嵌合凹部内への嵌合凸部２５の係合によるクリック感を頼りに押圧ヘッドの位置決めをすることができ、計量目盛りを注視して読み取る手間が不要である。
○上記嵌合凹部３９と嵌合凸部２５とにより、上記押圧ヘッド３１及びノズル３２の位置を、より正確に決定することができ、例えば容器を把持したときのノズル３２の向きが所要方向からずれて、容器を握り直すような不便を防止することができるので、使い勝手が良い。
【００２９】
請求項３の発明によれば、上記嵌合凹部３９を、上記係合凹溝３８の底面３８ａに縦設した嵌合縦溝で形成し、かつ上記嵌合凸部２５を上記ガイド筒２２上端の突条２３内周面に付設したから、該嵌合凸部２５が上記嵌合縦溝を横切る度にクリック感が得られ、段階的な計量が可能となる。
【００３０】
請求項４の発明によれば、上記嵌合凸部２５を、上記係合凹溝底面３８ａ乃至突条２３内周面に周方向へ等間隔に離間させて複数個設けたから、上記嵌合凸部を係合凹溝底面３８ａ乃至突条２３内周面の一側にのみ設けた場合の如く押圧ヘッド３１ががたついて昇降の円滑の妨げとなることを防止できる。

Field of application of the invention
The present invention relates to a liquid dispensing container that can be used for various liquids such as a cosmetic liquid. In this specification, the term "liquid" includes a liquid substance such as a cream.
[0002]
[Prior art]
The container according to Patent Literature 1 below is configured such that a funnel-shaped lower leg tube of a discharge member is screwed to an upper outer surface of a communication tube that rises from an outer surface of a container body neck and neck, and the middle portion of the communication tube in the vertical direction is connected to the upper tube.
