【発明の属する技術分野】
本発明は、魔法瓶等の液体容器に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
液体を詰入する容器本体の上部開口部に液体を注出可能不能とする液体注出装置を設け、この液体注出装置及び前記容器本体の上部を隠蔽するコップ状の蓋体を設け、この蓋体を前記容器本体の上部に被嵌し、この蓋体を回動操作して容器本体の上部に螺着する魔法瓶等の液体容器として様々なものが提案されている。
【０００３】
特に、液体注出装置に関しては、液体を注出可能としたり注出不能としたりする機構や液体の漏洩を防止する機構をどのようにするか、様々な改良案が提案されている。
【０００４】
例えば、実開昭６１−６７１１１号公報に開示されている液体容器では、液体注出装置の上面に、液体を注出可能とする弁を開く為の押しボタンと，この弁を閉じる為の押しボタンとを設けた構成であり、弁を開く為の押しボタンを押圧降下させるとこの押圧ボタンの降下量に比例して弁を閉じる為の押しボタンが上昇突出し、弁を閉じる構成を採用している（以下、第一従来例という。）。
【０００５】
また、例えば、実開平２−４０３４７号公報に開示されている液体容器では、液体注出装置の側面に押圧操作により没入する弁を閉じる為の押しボタンを突設し、この弁を閉じる為の押しボタンの没入量に比例して弁を閉じる構成を採用している（以下、第二従来例という。）。
【０００６】
しかし、これら第一従来例や第二従来例は、いずれも弁を閉じる為の押しボタンの押圧移動量によって弁を閉じる構成である為、この押圧操作を弁を閉じるまで確実に押圧しなければならず、押圧操作が厄介である。
【０００７】
しかも、もし弁を閉じる為の押しボタンの押圧操作が不十分であると、弁が閉じられず容器本体内の液体が漏洩してしまうおそれも発生してしまう。
【０００８】
本発明は、上記問題点を解決するもので、わずかの押圧量でも弁が確実に閉じられて液体抽出不能となる実用性，操作性，液体漏れ防止性に秀れた液体容器を提供することを目的としている。
【０００９】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。

【００１１】
また、前記係止体９として前記押圧降下体５若しくは前記押圧動作体７の押圧により弾圧変形する弾圧変形体９を採用し、この弾圧変形体９の弾圧変形により、前記押圧降下体５の係止部10と係止体９との係止が解除されるように構成したことを特徴とする請求項１記載の液体容器に係るものである。

【００１３】
また、前記弾性体８として杆体11にコイル状に設けた発条８を採用し、この杆体11の下部に前記液体注出装置３の液体注出経路14を開閉する開閉弁13を設け、前記押圧降下体５が降下した際、前記開閉弁13が降下して前記液体注出経路14を開き、前記押圧降下体５が上昇した際、前記開閉弁13が上昇して前記液体注出経路14を閉じるように構成したことを特徴とする請求項１〜３のいずれか１項に記載の液体容器に係るものである。
【００１４】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して説明する。
【００１５】
液体抽出装置３が液体注出可能な状態のとき、即ち、押圧部６が押圧されて押圧降下体５が降下位置に位置しているとき、押圧動作体７を手等で押圧すると前記降下位置に位置している押圧降下体５を弾性体８が強制的に押圧上昇せしめる為、押圧動作体７の押圧量がわずかであっても押圧降下体５が確実に上昇し、液体抽出装置３が確実に液体抽出不能な状態となる。
【００１６】
また、液体抽出装置３が液体注出不能な状態においては、押圧部６を押圧し、押圧降下体５を降下させることで前記液体抽出装置３が液体注出可能な状態となる。
【００１７】
【実施例】

【００１９】
また、前記押圧降下体５の前記押圧部６の下方に係止体９を上下動不能に設け、この係止体９が係止する係止部10を前記押圧降下体５の上下複数箇所（図面では２箇所）に設け、押圧降下体５を降下させた際、前記係止体９が押圧降下体５の上方の係止部10に係止し、前記押圧動作体７を押圧した際、前記押圧降下体５の上方の係止部10と係止体９との係止が解除され前記弾性体８の押圧作用により前記押圧降下体５が強制的に上昇されて液体注出不能になるように構成している。
【００２０】
また、係止体９としては、前記押圧降下体５及び前記押圧動作体７と当接し、この押圧降下体５や押圧動作体７の押圧により弾圧変形する弾圧変形体９を採用している。
【００２１】
また、この係止体９としては、前記押圧動作体７の押圧により左右巾が縮小して前記係止部10と係止体９との係止が解除され、この押圧動作体７の押圧の解除により、前記縮小した左右巾が元の左右巾に復元して前記係止部10と係止体９とが係止する構成の係止体９を採用している。
【００２２】
また、係止体９には、前記押圧動作体７の押圧が解除された際、縮小した係止体９の左右巾を元の左右巾に強制的に復元する弾性体16を設けている。
【００２３】
また、係止体９の側部に凸部17を設け、この凸部17を前記液体注出装置３に設けた嵌挿孔18に嵌挿することで、係止体９を液体注出装置３に対して上下動不能となるように設けている。尚、この凸部17と前記押圧動作体７とが当接し、押圧動作体７の押圧によって係止体９が弾圧変形するように構成している。
【００２４】
弾性体８としては、杆体11にコイル状に設けた発条８を採用している。また、この杆体11の上部に前記弾性体８の弾圧力により前記押圧降下体５の下部を押圧当接し得る当接部12を設け、この杆体11の下部に前記容器本体１の液体注出経路14を開閉する開閉弁13を設け、前記押圧降下体５が降下した際、前記開閉弁13が降下して前記容器本体１の液体注出経路14を開き、前記押圧降下体５が上昇した際、前記開閉弁13が上昇して前記容器本体１の液体注出経路14を閉じるように構成している。

【００２６】
図中、符号15は容器本体１の金属製の真空断熱二重容器部である。
【００２７】
以下、本実施例の作用について詳述する。
【００２８】
液体注出装置３から液体を注出不能な状態において、押圧降下体５は上昇位置にあり、係止体９は下方の係止部10に係止している（図１，２参照）。
【００２９】
押圧部６を押圧すると、押圧降下体５が係止体９を弾性変形して係止体９の左右巾が縮小し、前記係止体９と係止部10との係止が解除され、押圧降下体５の降下が可能となる。
【００３０】
同時に押圧降下体５が降下移動を開始し、この押圧降下体５と当接部12を介して当接している杆体11も降下移動を開始し、開閉弁13も降下移動を開始して容器本体１の液体注出経路14が開き、液体の注出が可能な状態となる。
【００３１】
更に押圧部６を押圧すると、押圧降下体５の降下により係止体９が上方の係止部10に係止可能な位置に達し、係止体９自身の弾圧変形作用と弾性体16の弾性作用とにより、係止体９の左右巾が元の左右巾に復元して係止体９が前記上方の係止部10に係止し、押圧部６の押圧を解除しても押圧降下体５が上昇しない状態となる（図３参照）。
【００３２】
この図３の状態で容器本体１内の液体を注出する。
【００３３】
この図３の状態から、容器本体１内の液体の注出を不能とする為には、押圧動作体７の先端部を少し押圧する。この押圧動作体７の押圧は、例えば、手での押圧や容器本体１の上部に蓋体４を被嵌した際の蓋体４と押圧動作体７との押圧当接によって行う。
【００３４】
押圧動作体７の先端部を少し押圧すると、押圧動作体７の基端部が係止体９を押圧して係止体９を弾圧変形させ、係止体９の左右巾が縮小されて前記係止体９と上方の係止部10との係止が解除される。
【００３５】
同時に、前記弾性体８の弾性作用により、杆体11の上部の当接部13が押圧降下体５を強制的に押圧上昇させ（図４参照）、且つ杆体11の下部の開閉弁12も強制的に上昇移動させられて容器本体１の液体注出経路14が閉じられ、液体注出が不能な状態となる。
【００３６】
同時に、押圧降下体５の上昇により係止体９が下方の係止部10に係止可能な位置に達し、係止体９の弾圧変形作用及び弾性体16の弾性作用により係止体９の左右巾が元の左右巾に復元して係止体９が前記下方の係止部10に係止し、押圧降下体５が上昇しない状態となる（図５参照）。
【００３７】
本実施例は上述のように構成したから、液体注出装置３が液体注出可能な状態において、押圧動作体７を少し押圧するだけで弾性体８の弾性作用により押圧降下体５が強制的に上昇移動され、液体注出装置３が確実に液体注出不能な状態となる実用性，操作性，液体の漏れ防止性に秀れた液体容器となる。
【００３８】
従って、例えば、容器本体１の上部に蓋体４を被嵌する際、蓋体４で押圧動作体７を少し押圧するだけでも押圧降下体５が上昇移動し、液体注出装置３が簡単且つ確実に液体注出不能な状態となる。
【００３９】
また、係止体９と上下の係止部10との係止により、液体の注出可能状態が維持されたり液体の注出不能状態が維持されたりすることになるから、簡単な係止構造によって液体注出装置３を所望の状態とすることができる実用性，生産性に秀れた液体容器となる。
【００４０】
また、係止体９として弾圧変形体９を採用したから、押圧部６の押圧や押圧動作体７の押圧により簡単に係止体９が弾圧変形して前記係止体９と上下の係止部10との係止，係止解除が行われることになる実用性に秀れた液体容器となる。
【００４１】
また、係止体９の弾圧変形の際、係止体９の縮小した左右巾の復元が弾性体16によってより一層確実に行われることになり、係止体９が係止している押圧降下体５の上昇位置及び降下位置での係止がより一層確実に行われることになるより一層実用性に秀れた液体容器となる。
【００４２】
また、押圧降下体５の上下移動とともに開閉弁13が上下移動して容器本体１の液体注出経路14が開閉するから、押圧降下体５の状態によって容器本体１の液体注出経路14の開閉状態を確知することができる実用性に秀れた液体容器となる。
【００４３】
【発明の効果】
本発明は上述のように構成したから、押圧動作体をわずかに押圧するだけでも弾性体８の弾性作用により確実に液体注出装置が液体注出不能な状態となる実用性，操作性，液体漏れ防止性に秀れた液体容器となる。
【００４４】
また、本発明においては、係止体と上下複数箇所に設けた係止部との係止によって液体注出装置が液体注出可能な状態を維持されたり液体注出不能な状態を維持されることになり、しかも、係止体と上方の係止部とが係止されている際に押圧動作体が押圧されると、押圧動作体の押圧によって前記係止体と上方の係止部との係止が解除され降下位置の押圧動作体が弾性体の押圧作用によって上昇するから、簡単な係脱機構によって確実に液体注出装置が液体注出不能な状態となる、より一層実用性に秀れた液体容器となる。
【００４５】
請求項２記載の発明においては、係止体として押圧降下体若しくは押圧動作体の押圧により弾圧変形する弾圧変形体を採用し、この弾圧変形体の弾圧変形により、係止体と係止部との係止が解除されるように構成したから、係止体と係止部との係脱機構を簡単に構成することができる、より一層実用性に秀れた液体容器となる。

In a state in which liquid cannot be dispensed from the liquid dispensing device 3, the pressing and lowering body 5 is in the raised position, and the locking body 9 is locked to the lower locking portion 10 (see FIGS. 1 and 2).
[0029]
When the pressing portion 6 is pressed, the pressing lowering body 5 elastically deforms the locking body 9 to reduce the right and left width of the locking body 9, and the locking between the locking body 9 and the locking portion 10 is released, The press lowering body 5 can be lowered.
[0030]
At the same time, the pressing and lowering body 5 starts to move downward, the casing 11 in contact with the pressing and lowering body 5 via the contact portion 12 also starts to move downward, and the on-off valve 13 also starts to move downward and the container body 1 liquid dispensing path 14 is opened, and the liquid can be dispensed.
[0031]
When the pressing part 6 is further pressed, the locking body 9 reaches a position where it can be locked to the upper locking part 10 by the lowering of the pressing lowering body 5, and the elastic body 16 is elastically deformed and the elastic body 16 is elastic. Due to the action, the left and right width of the locking body 9 is restored to the original left and right width, and the locking body 9 is locked to the upper locking portion 10, and even if the pressing of the pressing portion 6 is released, the pressing lowering body 5 will not rise (see FIG. 3).
[0032]
In the state of FIG. 3, the liquid in the container body 1 is poured out.
[0033]
In order to make it impossible to pour out the liquid in the container body 1 from the state of FIG. 3, the tip of the pressing body 7 is slightly pressed. The pressing body 7 is pressed by, for example, pressing by hand or pressing contact between the lid body 4 and the pressing body 7 when the lid body 4 is fitted on the upper portion of the container body 1.
[0034]
When the distal end portion of the pressing body 7 is slightly pressed, the base end portion of the pressing body 7 presses the locking body 9 to elastically deform the locking body 9, and the left and right widths of the locking body 9 are reduced to reduce the width. The locking between the locking body 9 and the upper locking portion 10 is released.
[0035]
At the same time, due to the elastic action of the elastic body 8, the contact portion 13 at the upper part of the casing 11 forcibly presses and raises the pressing and lowering body 5 (see FIG. 4), and the on-off valve 12 at the lower part of the casing 11 is also forced. As a result, the liquid dispensing path 14 of the container body 1 is closed, and the liquid cannot be dispensed.
[0036]
At the same time, as the pressing and lowering body 5 is raised, the locking body 9 reaches a position where it can be locked to the lower locking portion 10. The left and right width is restored to the original left and right width, and the locking body 9 is locked to the lower locking portion 10 so that the pressing and lowering body 5 does not rise (see FIG. 5).
[0037]
Since the present embodiment is configured as described above, in a state in which the liquid dispensing device 3 can dispense liquid, the pressing and lowering body 5 is forced by the elastic action of the elastic body 8 by pressing the pressing body 7 slightly. As a result, the liquid dispensing device 3 is excellent in practicality, operability, and liquid leakage prevention properties in which the liquid dispensing device 3 is surely incapable of liquid dispensing.
[0038]
Therefore, for example, when the lid body 4 is fitted on the upper part of the container body 1, the pressing and lowering body 5 moves up and down even if the pressing body 7 is slightly pressed by the lid body 4, and the liquid dispensing device 3 can be easily and It will be in the state where liquid pouring is certainly impossible.
[0039]
Further, since the liquid dischargeable state is maintained or the liquid discharge impossible state is maintained by the locking between the locking body 9 and the upper and lower locking portions 10, a simple locking structure is provided. As a result, the liquid dispensing device 3 can be brought into a desired state, and the liquid container is excellent in practicality and productivity.
[0040]
Further, since the elastic deformation body 9 is adopted as the engaging body 9, the engaging body 9 is easily elastically deformed by the pressing of the pressing portion 6 or the pressing operation body 7, so that the engaging body 9 and the upper and lower engaging portions are locked. The liquid container is excellent in practicality in that locking and unlocking with the portion 10 are performed.
[0041]
In addition, when the latching body 9 is elastically deformed, the reduced width of the latching body 9 is more reliably restored by the elastic body 16, and the pressure drop that the latching body 9 is latching is reduced. The liquid container is more practical because the locking of the body 5 at the raised position and the lowered position is more reliably performed.
[0042]
In addition, since the opening / closing valve 13 moves up and down with the vertical movement of the push-down body 5 and the liquid discharge path 14 of the container body 1 opens and closes, the liquid discharge path 14 of the container body 1 opens and closes depending on the state of the press-down body 5. It becomes a liquid container excellent in practicality capable of knowing the state.
[0043]
【The invention's effect】
Since the present invention is configured as described above, practicality, operability, and liquid in which the liquid pouring device is reliably incapable of liquid pouring by the elastic action of the elastic body 8 even by slightly pushing the pressing body. It becomes a liquid container with excellent leakage prevention.
[0044]
Further, in the present invention , the liquid dispensing device is maintained in a state in which liquid can be dispensed or in a state in which liquid cannot be dispensed by the engagement between the engaging body and the engaging portions provided at a plurality of positions above and below. In addition, when the pressing body is pressed when the locking body and the upper locking portion are locked, the locking body and the upper locking portion are pressed by the pressing operation body. Is released and the pressing operation body in the lowered position is raised by the pressing action of the elastic body, so that the liquid dispensing device can be surely made in a state in which liquid cannot be dispensed by a simple engagement / disengagement mechanism. An excellent liquid container.
[0045]
In the second aspect of the present invention, an elastic deformation body that is elastically deformed by pressing of a pressing lowering body or a pressing body is adopted as the engaging body, and the elastic body and the engaging portion are formed by the elastic deformation of the elastic deformation body. Therefore, the engagement / disengagement mechanism between the locking body and the locking portion can be easily configured, and the liquid container can be more practical.
[0046]
In the invention of claim 3, when the locking body having a reduced lateral width becomes the original lateral width in order to release the locking between the locking body and the locking portion, the elastic body is forced by the elastic action of the elastic body. Since the original width is restored to the original width, the locking body and the locking portion are more securely re-locked, and the pressing and lowering body is more securely locked at the ascending or descending position. It will be a liquid container that is even more practical.
[0047]
In the invention according to claim 4, since the on- off valve moves up and down as the press lowering body moves up and down to open and close the liquid pouring path of the container main body, the liquid pouring path of the container main body opens and closes depending on the state of the press lowering body. In addition, the liquid container is excellent in practicality in which the state can be ascertained and the liquid dispensing path is reliably opened and closed by the elastic action of the elastic body.
