Description

【０００１】
【発明の属する技術分野】
本発明は、瓶体等の容器の口部に設けられて、容器に収容された内容物を注出する注出口体に関する。
【０００２】
【従来の技術】
従来、醤油、ソース、食用油等の液体を内容物とする容器の口部に設けられ、未使用時に該容器を密封すると共に、開封後に、内容物を注出する注出口体が知られている。
【０００３】
この種の注出口体Ｂは、図４に示すように、容器Ｘの口部Ｙに嵌着された本体５０と、該本体５０の上部に着脱自在に冠着されたキャップ５１とによって構成されている。本体５０には、容器Ｘの内部に連通し、容器Ｘの内部に収容された内容物を案内する円筒状の注出部５２と、該注出部５２に包囲されてその内方に連設されたパネル部５３とを備えている。該パネル部５３には、環状に形成されたスコア５４と、該スコア５４に沿って破断されたときに開口する破断開口片５５が形成されており、スコア５４を破断するために破断開口片５５の上方に連設されたプルリング５６を備えている。スコア５４が破断されていない状態にあるときには、容器Ｘの内容物が密封状態とされている。
【０００４】
そして、容器Ｘの内容物を注出するときには、前記破断開口片５５を取り除いてパネル部５３を開口する。この開栓作業は、先ず、プルリング５６を引き上げることによりスコア５４を破断し、プルリング５６と共に破断開口片５５を取り除く。これによってパネル部５３に形成された開口５７を介して容器Ｘの内容物が注出自在とされる。
【０００５】
しかし、プルリング５６を引き上げる際には、比較的大きな引っ張り力を必要とし、しかも、大きな引っ張り力を掛けている途中でスコア５４が急激に破断される場合がある。そして、スコア５４の破断時の衝撃により容器Ｘに振れが生じ、開口５７から内容物が外部に飛散したり、また、プルリング５６と共に切除された破断開口片５５の裏面側に付着していた内容物が外部に飛散することがあり、その飛沫が作業者やその衣服に付着するといった不都合があった。
【０００６】
【発明が解決しようとする課題】
かかる不都合を解消して、本発明は、容器の内容物が飛散することなく開栓することができ、しかも開栓作業を容易に行うことができる注出口体を提供することを目的とする。
【０００７】
【課題を解決するための手段】
かかる目的を達成するために、本発明は、容器上部に設けられた口部に嵌着された本体と、該本体の外側に装着された外套体とによって構成されており、前記本体は、前記口部の外面に当接する筒状の外面当接部と、該外面当接部の上端縁に連設されて前記口部の上端縁に沿って水平に設けられた水平部と、該水平部の内周端に連設されて前記口部の内面に当接する筒状の内面当接部と、該内面当接部に包囲された内方に設けられたパネル部と、該パネル部を介して容器内部と連通して設けられて該内面当接部の先端部より上方に突出する筒状の注出部と、該注出部の上端縁にスコアを介して連設され、該注出部の内径より小径の外径を有し、該注出部より上方に突出する栓部とを備え、前記外套体は、前記栓部の頂部に対向する天板部と、該天板部の周縁から下方に延設されて前記外面当接部に外装され、前記天板部が前記栓部を押し下げて該栓部のスコアが破断されるまで、前記外面当接部に沿って下降する筒状の外筒部とを備えることを特徴とする。
【０００８】
本発明によれば、前記注出口体の本体に装着された前記外套体を該本体の軸線方向に押し下げることにより、前記栓部のスコアを破断することができる。即ち、先ず、前記外套体の天板部を下方に押圧する。このとき、外筒部が前記外面当接部に沿って下降して該天板部を下方に案内する。該天板部は、その下降に伴い前記栓部を押し下げる。これにより、前記スコアが破断され、栓部が前記注出部の上縁より切り離されて注出部内に挿入される。これによって、前記スコアの破断作業が完了する。このとき、従来のようなプルリング等を引き上げてスコアを破断する場合と異なり、栓部を押し下げてスコアを破断するので、容器の振れもなく、安定した状態でスコアを容易に破断することができる。また、スコアが破断された直後には、栓部が前記注出部に挿入状態となるので、該注出部が栓部によって塞がれた状態となり、内容物の飛散を確実に防止することができる。そして、注出部に挿入状態の栓部は、既にスコアが破断されているので、例えば外套体を取り外して、注出部を露出された後に、栓部を注出部から取り除くだけで、容器の内容物を注出することができる。また、注出部を開封後には、例えば外套体を取り付けて、容易に閉塞状態とすることができる。
【０００９】
また、本発明において、前記栓部の上端部は、一側から他側にかけて傾斜して形成されており、前記天板部は、該栓部の傾斜する上端部の高所に位置する頂部を押圧して前記スコアを破断することを特徴とする。これにより、前記天板部を押し下げたとき、その押圧力が栓部の傾斜する上端部の高所に対応する位置にあるスコアに部分的に集中して、スコアの破断開始を一層容易とすることができる。
【００１０】
また、本発明において、前記外套体の外筒部は、その上端部に着脱自在に冠着されたキャップを備え、該キャップは前記天板部を備えていることを特徴とする。これにより、前記栓部のスコアを破断する際には、外筒部にキャップを冠着した状態で、該キャップの天板部を押し下げる。これによって、キャップは外筒部と一体に下降し、前記栓部のスコアが破断される。また、スコアが破断され、注出部に挿入状態とされた栓部は、キャップを外筒部から取り外すだけで容易に露出させることができ、該栓部を取り除く作業を容易に行うことができる。更に、注出部を開封後には、外筒部にキャップを冠着するだけで容易に閉塞状態とすることができる。
【００１１】
また、本発明において、前記外面当接部には、前記外套体の外筒部の下縁から所定間隔を存して外方に突出する凸部が形成されており、前記外套体には、前記外筒部の下端縁に沿ってスコアを介して切除可能に連設され、下端縁が前記外面当接部の凸部に当接することにより、該外套体を所定位置に規制して前記天板部を前記栓部の未押圧状態に維持し、該スコアを介して切除することにより前記凸部への当接を解除して前記天板部による前記栓部の押圧を可能とする開封帯が設けられていることを特徴とする。
【００１２】
本発明の注出口体は、前述したように、前記外套体を押し下げることにより容易に開封される。そのため、例えば落下等により外部からの衝撃を受けて外套体が押し下げられた場合には、注出部が不用意に開封されるおそれがある。そこで、本発明において、前記開封帯を設けることにより、天板部が前記栓部を未押圧とする状態に維持するように前記外面当接部の凸部に開封帯の下端縁を当接して外套部の移動を規制することで、前述した衝撃等による外套体の移動を防止することができ、不用意な開封を確実に防止することができる。
【００１３】
また、本発明において、前記注出部は、前記内面当接部に包囲されたパネル部の径方向に互いに離間する位置に一対設けられ、夫々の注出部に前記栓部が設けられていることを特徴とする。本発明によれば、前記注出部を複数設けてもよく、単一である場合と同様に夫々の注出部に設けられた各栓部の頂部を天板部によって同時に押圧することで容易に開封することができる。そして、特にパネル部の径方向に互いに離間する位置に一対の注出部を設けておくことにより、夫々の栓部を取り除いて内容物を注出する際には、一方の注出部から内容物を注出するときに他方の注出部から容器内にエアを取り入れるようにし、一方の注出部を通過する内容物の脈動を防止することができる。
【００１４】
【発明の実施の形態】
本発明の一実施形態を図面に基づいて説明する。図１は本実施形態の注出口体の縦断面説明図、図２及び図３は開封工程を示す説明図である。

【００１７】
図１に示すように、前記本体１は、前記口部Ｙの上端部の外周面に圧接する円筒状の外面当接部３と、該外面当接部３の上端全周から前記口部Ｙの上端縁に沿って内方に延出された水平部４と、該水平部４の内周縁全周から連続して下方に延び、前記口部Ｙの上端部の内周面に圧接する円筒状の内面当接部５とを備えている。
【００１８】
内面当接部５の外径は、前記口部Ｙの内径よりも僅かに大径に形成されており、口部Ｙに挿着されたとき弾発的に収縮して口部Ｙの内面に密着する。外面当接部３の内径は、前記口部Ｙの外径よりも僅かに小径に形成されており、口部Ｙに外挿されたとき弾発的に拡径して口部Ｙの外面に密着する。
【００１９】
更に、外面当接部３の内周面には凸部６が形成されており、口部Ｙの外周に予め形成されている凹部７に係合して口部Ｙへの本体１の嵌着状態を強固に維持するようになっている。
【００２０】
また、前記内面当接部５の内方には、口部Ｙを閉塞するようにパネル部８が形成されており、該パネル部８の内面当接部５寄りの位置には、容器Ｘの内部に連通する円筒状の第１注出部９が形成されている。第１注出部９の上端縁には、スコア１０を介して円筒状の第１栓部１１が連設されている。該第１栓部１１は、その外径が第１注出部９の内径より小径に形成されており、スコア１０が破断されたときには、第１注出部９内に挿入自在となる。更に、第１栓部１１は、その上端を閉塞すると共に一方側に傾斜する傾斜面部１２を備えている。該傾斜面部１２の周縁部は第１栓部１１の上端から第１注出部９の内径よりも大きく外方に張り出しす鍔部１３を備えている。
【００２１】
また、該パネル部８の内面当接部５寄りであって、第１注出部９から内面当接部５の径方向に離間する位置には、容器Ｘの内部に連通する第１注出部９より小径の円筒状の第２注出部１４が形成されている。第２注出部１４の上端縁には、スコア１５を介して円柱状の第２栓部１６が連設されている。該第２栓部１６は、その外径が第２注出部１４の内径より小径に形成されており、スコア１５が破断されたときには、第２注出部１４内に挿入自在となる。更に、第２栓部１６は、その上端に一方側に傾斜する傾斜面部１７を備えている。該傾斜面部１７の周縁部は第２栓部１６の上端から第２注出部１４の内径よりも大きく外方に張り出しす鍔部１８を備えている。
【００２２】
前記外套体２は、前記本体１の外面当接部３の外周に装着された外筒部１９と、該外筒部１９の上端部に着脱自在に嵌着されたキャップ２０と、前記外筒部１９の下端縁にスコア２１を介して連設された開封帯２２とを備えている。
【００２３】
前記外筒部１９は、その上端部に縮径方向に水平に延びる縮径段部２３と、該縮径段部２３の内周から起立方向に延びる前記キャップ２０の嵌着部２４とを備えている。該嵌着部２４は、前記キャップ２０の内周壁に突出する突起２５が係合する溝部２６を備えている。また、前記外筒部１９の内周壁には、前記本体１の外面当接部３の外周壁に設けられた第１外周突起２７と、該第１外周突起２７の下方に設けられた第２外周突起２８とに係止可能な第１内周突起２９が形成されている。
【００２４】
前記キャップ２０は、前記本体１の上方を覆う天板部３０と、該天板部３０の周縁から下方に延びる枠部３１とにより構成されている。該枠部３１の内壁には前述した突起２５が形成されている。天板部３０の下面側には、両注出部９，１４の上端部に対応して夫々の注出部９，１４を閉塞する一対の筒状の閉塞部３２，３３が形成されている。更に、枠部３１の一部は、前記外筒部１９の縮径段部２３にヒンジ部３４を介して一体に連結されており、枠部３１の径方向に該ヒンジ部３４と対向する側には、舌片状の指掛け部３５が形成されている。
【００２５】
前記開封帯２２は、その内壁面に前記外面当接部３の第２外周突起２８に係止された第２内周突起３６を備えている。また、前記スコア２１の図示されない破断開始位置とされる該開封帯２２の該壁面の一部には把持部３７が形成されており、該把持部３７を把持して外方に引っ張ることによってスコア２１を破断し、該開封帯２２を取り除くことができるようになっている。また、該開封帯２２の下端縁は、前記外面当接部３の下端部に形成された凸部３８に当接されている。
【００２６】
図１示の状態においては、前記外筒部１９の第１内周突起２９が外面当接部３の第１外周突起２７に係止され、且つ開封帯２２の第２内周突起３６が外面当接部３の第２外周突起２８に係止されているので、外套体２の上方への移動が防止されている。また、開封帯２２の下端縁が外面当接部３の凸部３８に当接されていることによって外套体２は下方への移動が不能とされている。
【００２７】
次に、以上の構成からなる本実施形態の注出口体Ａの開封工程を説明する。先ず、図１に示す開封帯２２を切除する。該開封帯２２は、前記把持部３７を外方に引っ張ることによりスコア２１を介して外筒部１９の下縁回りに破断され、容易に取り除くことができる。開封帯２２が切り取られた状態を図２（ａ）に示す。
【００２８】
開封帯２２が切り取られることによって、図２（ａ）に示すように、外筒部１９の下方が開放され、外套体２が全体的に下方に移動する。これにより、前記キャップ２０の天板部３０が本体１の両栓部１１，１６の頂部３９，４０（傾斜面部１２，１７の高所に位置する分部）に当接する。
【００２９】
次いで、キャップ２０の天板部３０を下方に押し下げると、図２（ｂ）に示すように、両栓部１１，１６のスコア１０，１５の破断が開始される。このとき、両栓部１１，１６は、夫々の頂部３９，４０から押圧されるので、スコア１０，１５は、その一部に破断力が集中して付与され、初期破断が円滑に行われる。
【００３０】
続いて、更にキャップ２０の天板部３０を下方に押し下げると、図２（ｃ）に示すように、両栓部１１，１６は、夫々のスコア１０，１５が全周に亘って破断されて夫々第１注出部９及び第２注出部１４に挿入状態となる。
【００３１】
そして、図３（ａ）に示すように、外筒部１９は、その第１内周突起２９が外面当接部３の第２外周突起２８を乗り越えて、該外筒部１９の下端縁が外面当接部３の下端部に形成された凸部３８に当接され、同時に該外筒部１９の縮径段部２３が本体１の水平部４に当接される。しかも、外筒部１９はその第１内周突起２９が外面当接部３の第２外周突起２８に係止されて上方への移動が規制されるので、外筒部１９が本体１に一体に固定された状態となる。
【００３２】
次いで、キャップ２０を開け、図３（ｂ）に示すように、第１注出部９に挿入された第１栓部１１と、第２注出部１４に挿入された第２栓部１６とを取り除く。このときには既に、両栓部１１，１６はスコア１０，１５を介して両注出部９，１４から切り離されているので、両栓部１１，１６を両注出部９，１４から容易に取り除くことができる。しかも、両栓部１１，１６のスコア１０，１５が破断される際には、両栓部１１，１６が夫々の注出部９，１４に挿入状態となるので、両注出部９，１４が塞がれた状態となり、内容物の飛散を確実に防止することができる。
【００３３】
そして、図３（ｃ）に示すように、第１注出部９、第２注出部１４からの内容物の注出が可能となり、嵌着部２４にキャップ２０を嵌着することにより保管時に密封することができる。そして、図示しないが、内容物を注出する場合には、第１注出部９から内容物を注出するときに第２注出部１４から容器Ｘ内にエアが取り入れられ、注出時の内容物の脈動を防止することができる。
【００３４】
なお、本実施形態においては、一対の注出部９，１４を備えるものを挙げたが、注出部は単一であってもよく、或いは複数設けてもよい。
【００３５】
また、本実施形態においては、外套体２にキャップ２０を備える構成のものを挙げたが、図示しないが、外套体全体をキャップとして本体から取り外し自在とし、内容物注出時の開閉を行うようにしてもよい。こうすることにより、前述した開封帯２２により未開封時に外套体全体が本体１から取り外し不能となるので、悪戯による開封を防止して所謂ピルファープルーフ性を付与することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a spout body that is provided at a mouth portion of a container such as a bottle and that pours out the contents contained in the container.
[0002]
[Prior art]
Conventionally, there has been known a spout body that is provided at the mouth of a container containing liquids such as soy sauce, sauce, edible oil, etc., and seals the container when not in use, and pours the contents after opening. Yes.
[0003]
As shown in FIG. 4, this type of spout body B is constituted by a main body 50 fitted into the mouth Y of the container X and a cap 51 detachably crowned on the upper portion of the main body 50. ing. The main body 50 communicates with the inside of the container X, and has a cylindrical pouring part 52 that guides the contents accommodated in the container X, and is surrounded by the pouring part 52 and is continuous with the inside thereof. The panel unit 53 is provided. The panel portion 53 is formed with a score 54 formed in an annular shape and a break opening piece 55 that opens when the score 54 is broken along the score 54. The break opening piece 55 is used to break the score 54. Is provided with a pull ring 56 provided continuously thereabove. When the score 54 is not broken, the contents of the container X are sealed.
[0004]
When the contents of the container X are poured out, the break opening piece 55 is removed and the panel portion 53 is opened. In this plug opening operation, first, the pull ring 56 is pulled up to break the score 54, and the broken opening piece 55 is removed together with the pull ring 56. As a result, the contents of the container X can be poured out through the opening 57 formed in the panel portion 53.
[0005]
However, when pulling up the pull ring 56, a relatively large pulling force is required, and the score 54 may be abruptly broken while the large pulling force is being applied. Then, the container X is shaken by the impact at the time of breaking of the score 54, and the contents are scattered to the outside from the opening 57, or the contents attached to the back side of the breaking opening piece 55 cut out together with the pull ring 56 There is a problem in that an object may be scattered outside, and the splash may adhere to an operator or the clothes.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a spout body that can be opened without causing the contents of the container to scatter, and can be easily opened.
[0007]
[Means for Solving the Problems]
In order to achieve such an object, the present invention comprises a main body fitted in a mouth portion provided in an upper part of a container, and a mantle body mounted on the outside of the main body, A cylindrical outer surface abutting portion that abuts on the outer surface of the mouth portion, a horizontal portion that is connected to the upper edge of the outer surface abutting portion and is provided horizontally along the upper edge of the mouth portion, and the horizontal portion A cylindrical inner surface abutting portion that is connected to the inner peripheral edge of the inner surface of the inner surface of the mouth portion and is in contact with the inner surface of the mouth portion, an inwardly provided panel portion surrounded by the inner surface abutting portion, and the panel portion A cylindrical pouring portion provided in communication with the interior of the container and projecting upward from the tip of the inner surface abutting portion; and an upper end edge of the pouring portion, which is continuously provided via a score. An outer diameter that is smaller than the inner diameter of the portion, and a plug portion that protrudes upward from the pouring portion, and the outer shell includes a top plate portion that opposes the top portion of the plug portion, Extending downward from the periphery of the top plate portion and is externally mounted on the outer surface contact portion, and along the outer surface contact portion until the top plate portion pushes down the plug portion and the score of the plug portion is broken. And a cylindrical outer cylinder portion that descends downward.
[0008]
According to the present invention, the score of the plug portion can be broken by pushing down the outer shell mounted on the main body of the spout body in the axial direction of the main body. That is, first, the top plate portion of the mantle body is pressed downward. At this time, the outer cylinder part descends along the outer surface contact part to guide the top plate part downward. The top plate part pushes down the plug part as it descends. Thereby, the said score is fractured | ruptured, a plug part is cut off from the upper edge of the said extraction part, and is inserted in an extraction part. This completes the score breaking operation. At this time, unlike the conventional case where the score is broken by pulling up the pull ring or the like, the score is broken by pushing down the stopper portion, so that the score can be easily broken in a stable state without shaking of the container. . In addition, immediately after the score is broken, the plug portion is inserted into the extraction portion, so that the extraction portion is blocked by the plug portion and reliably prevents the contents from being scattered. Can do. And since the score of the plug part inserted in the pouring part has already been broken, for example, after removing the outer shell and exposing the pouring part, the plug part is simply removed from the pouring part. The contents of can be poured out. Moreover, after opening the extraction | pouring part, for example, a mantle body can be attached and it can be made into a closed state easily.
[0009]
Further, in the present invention, the upper end portion of the plug portion is formed to be inclined from one side to the other side, and the top plate portion has a top portion located at a height of the inclined upper end portion of the plug portion. The score is broken by pressing. Thereby, when the top plate part is pushed down, the pressing force is partially concentrated on the score at a position corresponding to the height of the upper end part where the stopper part is inclined, thereby making it easier to start breaking the score. be able to.
[0010]
In the present invention, the outer cylinder portion of the outer shell includes a cap that is detachably attached to an upper end portion thereof, and the cap includes the top plate portion. Thereby, when breaking the score of the plug portion, the top plate portion of the cap is pushed down with the cap attached to the outer tube portion. As a result, the cap is lowered integrally with the outer cylinder portion, and the score of the plug portion is broken. Further, the plug portion whose score has been broken and inserted into the extraction portion can be easily exposed by simply removing the cap from the outer cylinder portion, and the operation of removing the plug portion can be easily performed. . Furthermore, after opening the pouring part, it can be easily closed by simply attaching a cap to the outer cylinder part.
[0011]
Further, in the present invention, the outer surface contact portion is formed with a convex portion protruding outward from the lower edge of the outer tube portion of the outer shell at a predetermined interval. the outer cylindrical portion along the bottom edge is resected capable consecutively through the score, by the lower edge abuts the convex portion of the outer surface abutting portion, the top and regulating該Gaito body in a predetermined position An opening band that maintains the plate portion in an unpressed state of the plug portion and releases the contact with the convex portion by cutting through the score so that the plug portion can be pressed by the top plate portion. Is provided.
[0012]
As described above, the spout body of the present invention is easily opened by pushing down the outer shell. For this reason, for example, when the outer body is pushed down due to an impact from the outside due to dropping or the like, the extraction portion may be unintentionally opened. Therefore, in the present invention, by providing the opening band, the lower end edge of the opening band is brought into contact with the convex part of the outer surface contact part so that the top plate part maintains the stopper part in an unpressed state. By restricting the movement of the mantle portion, it is possible to prevent the mantle body from moving due to the aforementioned impact or the like, and to prevent inadvertent opening.
[0013]
In the present invention, a pair of the extraction portions are provided at positions spaced apart from each other in the radial direction of the panel portion surrounded by the inner surface contact portion, and the plug portion is provided in each extraction portion. It is characterized by that. According to the present invention, a plurality of the extraction portions may be provided, and it is easy to press the top portions of the respective plug portions provided in the respective extraction portions simultaneously with the top plate portion as in the case of a single case. Can be opened. In particular, by providing a pair of pouring parts at positions spaced apart from each other in the radial direction of the panel part, when removing the respective plug parts and pouring the contents, the contents from one pouring part When an object is poured out, air can be taken into the container from the other pouring part, and the pulsation of the contents passing through the one pouring part can be prevented.
[0014]
