Description
本発明は、内容物を充填した容器本体の口部に装着される注出栓に関するものである。 The present invention relates to a spout attached to the mouth of a container body filled with contents.
例えばシャンプーやリンス、化粧品、整髪料、医薬品等の内容物を収容した容器本体の口部に装着される注出栓としては、例えば合成樹脂等によって形成され、使用前には容器本体の充填空間を密閉し、使用する直前に引きちぎりによって開封する、引きちぎりタイプの注出栓が知られている。このような注出栓として例えば特許文献１には、薄肉部を介して一体連結するもぎり栓部を有し、使用時には、このもぎり栓部を摘んで引っ張ることで薄肉部を破断させて、もぎり栓部を引きちぎって容器本体を開封する注出栓が示されている。 For example, the spout plug to be attached to the mouth of the container main body containing contents such as shampoo, rinse, cosmetics, hairdressing agent, medicine, etc. is formed of, for example, a synthetic resin and the filling space of the container main body before use A tear-off type pouring tap is known that seals and is opened by tearing immediately before use. As such a spout plug, for example, Patent Document 1 has a mortar plug portion that is integrally connected through a thin wall portion. A spout is shown that tears off the closure and opens the container body.
ところで、上述した引きちぎりタイプの注出栓は、容器本体に装着される注出栓本体部分と、引きちぎられる栓体部分とを一体連結しており、これらを１つの部材で構成することができるため、部材コストの削減に大きく寄与することができる反面、栓体部分の引きちぎりによって形成される注出栓本体部分の注出口は、その縁面が毛羽だったように荒れた状態（ギザギザ状）になってしまうことが通常である。このため、内容物を注出する際、注出口付近で内容物の流れが乱れやすくなり、特にこのタイプの注出栓を詰替え容器に適用した場合にあっては、相手方となる詰替えるべき容器の受給栓を通して内容物の詰替えを行うに際し、受給可能範囲が狭いため、所期した通りに内容物を注出することができずに周囲を汚してしまうおそれがあった。また、このように荒れた状態の注出口にあっては注出後の液切れも悪く、これらの不具合を解決した新たな注出栓の出現が、従来から強く望まれていた。 By the way, the tear-off type pouring tap mentioned above has integrally connected the pouring plug main-body part with which the container main body is mounted, and the plug body part to be torn off, and these can be comprised by one member. Therefore, while it can greatly contribute to the reduction of the material cost, the spout of the spout main body formed by tearing off the plug body is in a rough state as if its edge surface was fuzzy (a jagged shape) ) Is usually. For this reason, when the contents are poured out, the flow of the contents tends to be disturbed in the vicinity of the spout, and especially when this type of spout is applied to a refill container, it should be refilled as the counterpart. When refilling the contents through the receptacle tap, the receivable range is narrow, so the contents could not be poured out as expected and the surroundings could be soiled. Further, in such a rough spout, the liquid drainage after pouring is bad, and the appearance of a new spout tap that solves these problems has been strongly desired.
本発明の課題は、引きちぎりタイプの注出栓に関し、内容物の流れが乱れずに所期した通りに注出できる上、注出後の液切れにも優れる新規な注出栓を提案するところにある。 An object of the present invention relates to a tear-off type pouring tap, and proposes a novel pouring tap that can be poured out as expected without disturbing the flow of the contents, and also excellent in drainage after pouring. By the way.
本発明は、容器本体の充填空間につながる貫通孔を有し該容器本体の口部に装着されるベースと、該貫通孔を取り囲んで立ち上がるとともにその上部開口を閉鎖して該充填空間を封止する外筒とを備え、該外筒に設けた破断予定線に沿う引きちぎりにて内容物の注出を可能とする注出栓であって、
前記外筒の内側に、連結部を介して該外筒の内壁に一体連結するとともにその先端に前記充填空間内の内容物を注出する注出口を有する内筒を設け、
前記破断予定線は、前記外筒の全周にわたって環状に設けられ、
前記破断予定線が破断することで前記外筒の上部が引きちぎられ、前記内筒の注出口が露出することを特徴とする注出栓である。
The present invention has a through-hole connected to the filling space of the container body, a base attached to the mouth of the container body, and stands up surrounding the through-hole and closes its upper opening to seal the filling space An extraction tube that allows the content to be extracted by tearing along a planned fracture line provided on the outer tube,
Provided on the inside of the outer cylinder is an inner cylinder that is integrally connected to the inner wall of the outer cylinder via a connecting portion and has a spout for pouring out the contents in the filling space at the tip .
The planned fracture line is provided in an annular shape over the entire circumference of the outer cylinder,
An upper part of the outer cylinder is torn off when the planned fracture line is broken, and the spout of the inner cylinder is exposed .
前記連結部は、上方から下方に向けて傾斜する傾斜壁であり、該傾斜壁の下端部に前記充填空間に連通する液戻し孔を設けることが望ましい。 The connecting portion is an inclined wall that is inclined downward from above, and a liquid return hole that communicates with the filling space is preferably provided at a lower end portion of the inclined wall.
前記内筒の注出口は、前記傾斜壁と同方向に傾く傾斜開口であることが望ましい。 The spout of the inner cylinder is preferably an inclined opening that is inclined in the same direction as the inclined wall.
前記連結部は、上方から下方に向けて傾斜する傾斜壁であり、前記内筒の注出口は、該傾斜壁と同方向に傾く傾斜開口であって、
前記傾斜開口の下端部を前記傾斜壁の下端部に接続するとともに、この接続部に該接続部から前記充填空間に向けて伸延する液戻しリブを設けることが望ましい。
The connecting portion is an inclined wall that is inclined downward from above, and the spout of the inner cylinder is an inclined opening that is inclined in the same direction as the inclined wall,
It is desirable to connect the lower end portion of the inclined opening to the lower end portion of the inclined wall, and to provide a liquid return rib extending from the connection portion toward the filling space.
前記接続部の頂壁は、前記傾斜壁の傾斜する向きと反対方向に傾く傾斜頂壁であることが望ましい。 It is preferable that the top wall of the connecting portion is an inclined top wall that is inclined in a direction opposite to the direction in which the inclined wall is inclined.
容器本体の口部に装着されるベースに、破断予定線を備えるとともに上部開口を閉鎖して容器本体の充填空間を封止する外筒を一体連結し、その外筒の内側に、連結部を介して外筒の内壁に一体連結するとともにその先端に前記充填空間内の内容物を注出する注出口を有する内筒を設けたので、破断予定線に沿う外筒上部の引きちぎりによって、内筒の注出口を露出させることができる。この場合、注出口の縁面は滑らかな状態のままであるので、内容物を乱れなく注出させることができ、また注出後の液切れも良好となる。このため、本発明の注出栓は特に、詰替えるべき容器の受給栓に向けて内容物を所期した通りに注出させることが必要な、詰替え容器の注出栓として好適である。
また、注出栓は、一体で形成することができるので、従来の引きちぎりタイプの注出栓と同様に、部品コストを十分に抑制することができる。
An outer cylinder that includes a planned fracture line and closes the upper opening to seal the filling space of the container main body is integrally connected to a base that is attached to the mouth portion of the container main body, and a connecting portion is provided inside the outer cylinder. The inner cylinder is integrally connected to the inner wall of the outer cylinder, and an inner cylinder having a spout for pouring out the contents in the filling space is provided at the tip of the inner cylinder. The outlet of the tube can be exposed. In this case, since the edge surface of the spout remains in a smooth state, the contents can be poured out without being disturbed, and liquid drainage after pouring can be improved. For this reason, the pouring tap of the present invention is particularly suitable as a pouring tap for a refill container that requires the contents to be poured out as expected toward the receiving tap of the container to be refilled.
Moreover, since the pouring tap can be integrally formed, the parts cost can be sufficiently suppressed as in the case of the conventional tear-off type pouring tap.
内筒と外筒とを一体連結する連結部を、上方から下方に向けて傾斜する傾斜壁とし、この傾斜壁の下端部に充填空間に連通する液戻し孔を設ける場合は、横倒しや反転姿勢等により内筒の上方及び外側に貯溜された内容物をこの液戻し孔から充填空間内に速やかに回収することができるので、引きちぎりにて外筒を破断する際の液だれを有効に防止することができる。 When the connecting part that connects the inner cylinder and the outer cylinder integrally is an inclined wall that is inclined downward from above, and a liquid return hole that communicates with the filling space is provided at the lower end of the inclined wall, the sideways or inverted position The contents stored above and outside the inner cylinder can be quickly collected into the filling space from this liquid return hole, etc., effectively preventing dripping when tearing the outer cylinder. can do.
内筒の注出口を、傾斜壁と同方向に傾く傾斜開口とする場合は、注出口の縁部に付着した内容物が、その縁部を伝って液戻し孔が設けられている側に向けて流れるので、注出口に付着していた内容物を液戻し孔に流れ込ませやすくなり、液戻し効果をより効果的に発揮させることができる。
更に、内容物注出時の傾倒姿勢の方向性を容易に認識することができ、スムーズな注出操作を可能とする。
When the outlet of the inner cylinder is an inclined opening inclined in the same direction as the inclined wall, the contents attached to the edge of the outlet are directed to the side where the liquid return hole is provided along the edge. Therefore, the contents adhering to the spout can easily flow into the liquid return hole, and the liquid return effect can be exhibited more effectively.
Furthermore, it is possible to easily recognize the direction of the tilting posture when the contents are poured out, and a smooth dispensing operation is possible.
ここで、内筒と外筒とを一体連結する連結部を、上方から下方に向けて傾斜する傾斜壁とし、内筒の注出口を、傾斜壁と同方向に傾く傾斜開口とするとともに、傾斜開口の下端部を前記傾斜壁の下端部に接続し、この接続部に、該接続部から充填空間に向けて伸延する液戻しリブを設ける場合は、内筒の上方及び外側に貯溜された内容物及び注出口の縁部に付着した内容物をこの接続部周辺に集めることができ、さらに、集まった内容物を、液戻しリブを伝わらせて充填空間内に流れ込ませることができるので、液戻し効果が十分に発揮される。 Here, the connecting portion that integrally connects the inner cylinder and the outer cylinder is an inclined wall that is inclined downward from above, and the outlet of the inner cylinder is an inclined opening that is inclined in the same direction as the inclined wall. When the lower end portion of the opening is connected to the lower end portion of the inclined wall, and the liquid return rib extending from the connection portion toward the filling space is provided at the connection portion, the contents stored above and outside the inner cylinder The contents adhering to the edge of the product and the spout can be collected around the connecting portion, and further, the collected content can flow along the liquid return rib and flow into the filling space. The return effect is fully exhibited.
接続部の頂壁を、傾斜壁の傾斜する向きと反対方向に傾く傾斜頂壁とする場合は、接続部周辺に向けて流れてくる内容物に逆向きの流れを与えることができるので、流れの変化によって接続部周辺に集まった内容物が溜まりにくくなり、液戻し効果を一層有効に発揮させることができる。 When the top wall of the connecting part is an inclined top wall that is inclined in the direction opposite to the direction in which the inclined wall inclines, it is possible to give a reverse flow to the contents flowing toward the periphery of the connecting part. As a result of this change, the contents gathered around the connection portion are less likely to accumulate, and the liquid return effect can be more effectively exhibited.
以下、図面を参照して、本発明をより具体的に説明する。
図１は、本発明に従う注出栓の実施の形態を示す、側面視での断面図、Ａ−Ａに沿う断面図であって、図２は、図１に示す注出栓の上部開口を閉鎖して、容器の口部に装着した平面図、側面視での断面図、Ｂ−Ｂに沿う断面図である。
Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a cross-sectional view in a side view showing an embodiment of a spout according to the present invention, a cross-sectional view along A-A, and FIG. 2 shows an upper opening of the spout shown in FIG. It is the top view which closed and was equipped with the opening | mouth part of the container, sectional drawing in side view, and sectional drawing in alignment with BB.
図１において、１０は容器本体の口部に装着されるベースである。図示の例でベース１０は、円板状の天壁１１の縁部より垂下される環状壁１２を有し、天壁１１の中央部にその表裏を貫く貫通孔１３を備えている。環状壁１２の内面には、容器本体の口部に係合する注出栓側ねじ部１２ａが設けられている。なお、注出栓側ねじ部１２ａに代えて、アンダーカットで係合するようにしてもよい。また、図示の例では、環状壁１２の下端開口に、容器本体に装着された際にベース１０の回り止めとなる注出栓側凸部１２ｂが設けられている。注出栓側凸部１２ｂの回り止めとしての機能は、後述する。さらに、天壁１１の裏面には、環状壁１２から半径方向内側に間隔をあけて設けられる内側環状壁１４が一体連結している。 In FIG. 1, reference numeral 10 denotes a base attached to the mouth of the container body. In the illustrated example, the base 10 has an annular wall 12 that hangs down from the edge of a disk-shaped top wall 11, and a through hole 13 that penetrates the front and back of the top wall 11. On the inner surface of the annular wall 12, a spout side screw portion 12 a that engages with the mouth portion of the container body is provided. In addition, it may replace with the pouring tap side screw part 12a, and you may make it engage with an undercut. In the illustrated example, a spout-side convex portion 12b that serves as a detent for the base 10 when mounted on the container body is provided at the lower end opening of the annular wall 12. The function as a rotation stopper of the spout side convex portion 12b will be described later. Further, an inner annular wall 14 provided integrally with the rear surface of the top wall 11 with a space inward in the radial direction from the annular wall 12 is integrally connected.
２０は、貫通孔１３を取り囲んで立ち上がり、ベース１０と一体連結する外筒である。外筒２０は、図１のＡ−Ａ断面に示す例では円筒状となっているが、筒状であればよく、多角形の筒状であってもよい。また、外筒２０は、引きちぎりによって破断する破断予定線２１を備えている。図示の例では、環状の薄肉部を設けて破断予定線２１を形成しているが、外筒２０の上部及び下部を形成する材料に対し、破断予定線２１を形成する部位を強度の弱い材料で形成して、これらを例えば二色成形で一体連結するようにしてもよい。 Reference numeral 20 denotes an outer cylinder that surrounds the through-hole 13 and rises integrally with the base 10. Although the outer cylinder 20 is cylindrical in the example shown in the AA cross section of FIG. 1, it may be cylindrical and may be a polygonal cylinder. Moreover, the outer cylinder 20 is provided with the fracture | rupture planned line 21 fractured | ruptured by tearing. In the example shown in the figure, an annular thin portion is provided to form the planned fracture line 21, but the material that forms the planned fracture line 21 is made of a material that is weaker than the material that forms the upper and lower portions of the outer cylinder 20. These may be integrally connected by, for example, two-color molding.
また、外筒２０の上部には上部開口２２が設けられている。上部開口２２は、例えば射出成形等で形成された時点においては、図１に示すように開口しているが、その後、熱を加えて溶着させたり接着剤等で接着したりすることで、図２に示すように壁面同士を固着して閉鎖される。 Further, an upper opening 22 is provided in the upper part of the outer cylinder 20. The upper opening 22 is opened as shown in FIG. 1 when it is formed by, for example, injection molding or the like. After that, the upper opening 22 is heated and welded or bonded with an adhesive or the like. As shown in FIG. 2, the wall surfaces are fixed and closed.
さらに、外筒２０には、破断予定線２１よりも上方に、摘み部２３を設けることが好ましい。これにより、摘み部２３を介して外筒２０の上部が引き上げられやすくなるので、引きちぎり作業が容易に行えることとなる。また、摘み部２３には、指掛かり部２３ａを設けることが好ましい。 Further, the outer cylinder 20 is preferably provided with a knob 23 above the planned break line 21. Thereby, since the upper part of the outer cylinder 20 becomes easy to be pulled up via the knob | pick part 23, a tearing operation | work can be performed easily. Moreover, it is preferable to provide the finger grip part 23 a in the knob part 23.
３０は、外筒２０の内側に設けられる内筒である。図１に示すように内筒３０は、外筒２０の内壁２０ａに、連結部３１を介して一体連結されている。ここで、連結部３１は、容器本体の口部に取り付けられた際に、上方となる側から下方となる側に向けて傾斜する傾斜壁であることが好ましく、また、その下方となる側には、連結部３１の表裏を貫通する液戻し孔３２を設けることが好ましい。 Reference numeral 30 denotes an inner cylinder provided inside the outer cylinder 20. As shown in FIG. 1, the inner cylinder 30 is integrally connected to the inner wall 20 a of the outer cylinder 20 via a connecting portion 31. Here, when the connecting portion 31 is attached to the mouth portion of the container body, the connecting portion 31 is preferably an inclined wall that is inclined from the upper side toward the lower side, and on the lower side thereof. Is preferably provided with a liquid return hole 32 penetrating the front and back of the connecting portion 31.
内筒３０の頂部は、容器本体の充填空間内からの内容物を注出する注出口３３となっている。図１に示すように注出口３３は、上述した傾斜壁と同方向に傾く傾斜開口であることが好ましい。また、注出口３３には、内容物の液切れ効果を十分に発揮させるべく、僅かに外側に湾曲させたリップ３３ａを設けることが好ましい。 The top of the inner cylinder 30 serves as a spout 33 for pouring out the contents from the filling space of the container body. As shown in FIG. 1, the spout 33 is preferably an inclined opening inclined in the same direction as the inclined wall described above. Moreover, it is preferable to provide the spout 33 with a lip 33a that is slightly curved outward so that the content can be fully drained.
上記のように構成される注出栓は、図２に示すように容器本体４０の口部４１に装着される。口部４１の外面には、注出栓側ねじ部１２ａに対応する口部側ねじ部４１ａが形成されており、注出栓を容器本体４０に対して最後までねじ込むことで装着が完了する。なおこの場合、注出栓の内側環状壁１４は、口部４１の内面に液密に当接しているので、容器本体４０の充填空間Ｍ内に収容される内容物が、注出栓と口部４１との隙間から漏れ出すおそれがない。また、口部４１には、図２のＢ−Ｂ断面（ねじ込み終了直前の状態）に示すように口部側凸部４１ｂが設けられていて、図の矢印の向きに回転させると、注出栓側凸部１２ｂが口部側凸部４１ｂを乗り越えてねじ込みが終了する。これによりねじ込み終了後は、注出栓側凸部１２ｂと口部側凸部４１ｂとの係合によって、簡単には注出栓を逆方向側へ回転させることができないので、不用意な注出栓の取り外しが防止される。 The pouring tap configured as described above is attached to the mouth portion 41 of the container body 40 as shown in FIG. On the outer surface of the mouth portion 41, a mouth side screw portion 41a corresponding to the spout tap side screw portion 12a is formed, and the mounting is completed by screwing the spout tap into the container body 40 to the end. In this case, since the inner annular wall 14 of the spout is in liquid-tight contact with the inner surface of the mouth portion 41, the contents accommodated in the filling space M of the container body 40 are the spout and the spout. There is no risk of leaking from the gap with the portion 41. Moreover, the mouth part 41 is provided with a mouth part side convex part 41b as shown in the BB cross section in FIG. 2 (a state immediately before the end of screwing). The plug-side convex portion 12b gets over the mouth-side convex portion 41b and the screwing is finished. Thus, after the screwing is finished, the spout can not be easily rotated in the reverse direction due to the engagement between the spout side convex portion 12b and the mouth side convex portion 41b. Removal of the plug is prevented.
その後、摘み部２３を引き上げると、外筒２０は破断予定線２１で破断して、摘み部２３を伴う外筒２０の上部が引きちぎられ、内筒３０の注出口３３が露出する。ここで、内筒３０の内側は、容器本体４０の充填空間Ｍにつながっているので、容器本体４０を傾倒姿勢に変移させることによって、充填空間Ｍ内の内容物をその流れを乱すことなく注出させることができ、また、注出後の液切れも良好となる。 Thereafter, when the knob portion 23 is pulled up, the outer cylinder 20 is broken at the planned breaking line 21, the upper portion of the outer cylinder 20 with the knob portion 23 is torn off, and the spout 33 of the inner cylinder 30 is exposed. Here, since the inside of the inner cylinder 30 is connected to the filling space M of the container body 40, the contents in the filling space M can be poured without disturbing the flow thereof by changing the container body 40 to the tilted posture. In addition, it is possible to remove liquid after pouring.
そして、図２に示すように連結部３１を、上述した傾斜壁とし、また、この傾斜壁の下端部に充填空間に連通する液戻し孔３２を設ける場合は、固着閉鎖した外筒２０の上部開口２２と内筒３０の間に形成される空間領域や内筒３０外側に貯溜される内容物を傾斜壁の下端側に集めて、液戻し孔３２から充填空間Ｍ内に回収することができるので、引きちぎりにて外筒を破断する際の液だれが有効に防止される。 As shown in FIG. 2, when the connecting portion 31 is the above-described inclined wall and the liquid return hole 32 communicating with the filling space is provided at the lower end portion of the inclined wall, the upper portion of the outer cylinder 20 that is firmly closed is closed. The space area formed between the opening 22 and the inner cylinder 30 and the contents stored on the outer side of the inner cylinder 30 can be collected on the lower end side of the inclined wall and recovered from the liquid return hole 32 into the filling space M. Therefore, dripping at the time of breaking the outer cylinder by tearing is effectively prevented.
また、図２に示すように注出口３３を、傾斜壁である連結部３１と同方向に傾く傾斜開口とする場合は、注出口３３の縁部に付着した内容物が、注出口３３の縁部を伝い、液戻し孔３２が設けられている側に向けて流れるので、液戻し孔３２に流れ込ませやすくなり、液戻し効果をより効果的に発揮させることができる。
更に、内容物注出時の傾倒姿勢の方向性を容易に認識することができ、スムーズな注出操作を可能とする。
In addition, as shown in FIG. 2, when the spout 33 is an inclined opening inclined in the same direction as the connecting portion 31 that is an inclined wall, the contents attached to the edge of the spout 33 are the edges of the spout 33. Since it flows toward the side where the liquid return hole 32 is provided, it can easily flow into the liquid return hole 32, and the liquid return effect can be more effectively exhibited.
Furthermore, it is possible to easily recognize the direction of the tilting posture when the contents are poured out, and a smooth dispensing operation is possible.
なお、摘み部２３は、連結部３１が傾斜壁である場合、図示のように傾斜方向が下方となる側に設けることが好ましい。これにより、摘み部２３を、図２に示す矢印の向きに傾けながら引き上げるにあたり、内筒３０が邪魔になることがないので、引きちぎり作業が容易となる。 In addition, when the connection part 31 is an inclined wall, it is preferable to provide the knob | pick part 23 in the side from which an inclination direction becomes downward like illustration. Thereby, when pulling up the knob 23 while tilting in the direction of the arrow shown in FIG. 2, the inner cylinder 30 does not get in the way, so that the tearing operation becomes easy.
次に、図３及び図４を参照して、本発明に従う他の注出栓について具体的に説明する。
図３は、本発明に従う他の注出栓の実施の形態を示す、平面図、側面視での断面図、Ｃ−Ｃに沿う断面図であって、図４は、図３に示す注出栓の上部開口を閉鎖して、容器の口部に装着した側面視での断面図である。なお、上述した図１、図２に示す注出栓と同一の機能を有する部位については、同一の符号を付して、説明は省略する。
Next, with reference to FIG.3 and FIG.4, the other pouring stopper according to this invention is demonstrated concretely.
3 is a plan view, a cross-sectional view in side view, and a cross-sectional view along C-C showing an embodiment of another pouring tap according to the present invention. FIG. 4 is a pouring shown in FIG. It is sectional drawing in the side view which closed the upper opening of the stopper and was mounted | worn with the opening part of the container. In addition, about the site | part which has the same function as the pouring tap shown to FIG. 1, FIG. 2 mentioned above, the same code | symbol is attached | subjected and description is abbreviate | omitted.
図３に示す１３０は、外筒２０の内側に設けられる内筒である。内筒１３０は、外筒２０の内壁２０ａに、連結部１３１を介して一体連結されている。ここで、連結部１３１は、容器本体の口部に取り付けられた際に、上方となる側から下方となる側に向けて傾斜する傾斜壁となっている。内筒１３０の頂部は、容器本体の充填空間内からの内容物を注出する注出口１３３となっている。また、注出口１３３は、上述した傾斜壁と同方向に傾く傾斜開口となっている。そしてこれらの場合、傾斜開口の下端部を傾斜壁の下端部に接続するとともに、この接続部１３４に、接続部１３４から充填空間Ｍに向けて伸延する液戻しリブ１３５を設けることが好ましい。また、注出口１３３には、内容物の液切れ効果を十分に発揮させるべく、僅かに外側に湾曲させたリップ１３３ａを設けることが好ましい。 Reference numeral 130 shown in FIG. 3 denotes an inner cylinder provided inside the outer cylinder 20. The inner cylinder 130 is integrally connected to the inner wall 20 a of the outer cylinder 20 via a connecting portion 131. Here, the connecting part 131 is an inclined wall that inclines from the upper side toward the lower side when attached to the mouth of the container body. The top portion of the inner cylinder 130 serves as a spout 133 for pouring the contents from the filling space of the container body. The spout 133 is an inclined opening that is inclined in the same direction as the inclined wall described above. In these cases, it is preferable that the lower end portion of the inclined opening is connected to the lower end portion of the inclined wall, and the connection portion 134 is provided with a liquid return rib 135 extending from the connection portion 134 toward the filling space M. Moreover, it is preferable to provide the spout 133 with a lip 133a that is slightly curved outward so that the content can be fully drained.
そして、図３に示すように、接続部１３４の頂壁１３４ａは、傾斜壁の傾斜する向きと反対方向に傾く中心側が低い傾斜頂壁であることが好ましい。 And as shown in FIG. 3, it is preferable that the top wall 134a of the connection part 134 is an inclination top wall with a low center side inclined in the direction opposite to the inclination direction of an inclination wall.
上記のように構成される注出栓を、図４に示すように容器本体４０の口部４１に装着し、摘み部２３を引き上げると、外筒２０は破断予定線２１で破断して、摘み部２３を伴う外筒２０の上部が引きちぎられ、内筒１３０の注出口１３３が露出する。そして、図４に示す注出栓においても、注出口１３３の縁面は滑らかな状態のままであるので、充填空間Ｍ内の内容物をその流れを乱すことなく注出させることができ、また、注出後の液切れも良好となる。 When the spout configured as described above is attached to the mouth portion 41 of the container main body 40 as shown in FIG. 4 and the knob 23 is pulled up, the outer cylinder 20 is broken at the planned breaking line 21 and the knob is picked. The upper part of the outer cylinder 20 with the part 23 is torn off, and the spout 133 of the inner cylinder 130 is exposed. And since the edge surface of the spout 133 remains smooth in the spout shown in FIG. 4, the contents in the filling space M can be poured out without disturbing the flow, Also, liquid drainage after pouring is improved.
そして、図４に示すように連結部１３１を、上述した傾斜壁とし、注出口１３３を、傾斜壁である連結部１３１と同方向に傾く傾斜開口とするとともに、傾斜開口の下端部を傾斜壁の下端部に接続し、この接続部１３４に液戻しリブ１３５を設ける場合は、内筒１３０の外側に付着した内容物及び注出口１３３の縁部に付着した内容物をこの接続部１３４周辺に集めることができ、さらに、集まった内容物を、液戻しリブ１３５を伝わらせて充填空間Ｍ内に流れ込ませることができるので、液戻し効果を十分に発揮させることが可能となる。 As shown in FIG. 4, the connecting portion 131 is the inclined wall described above, the spout 133 is an inclined opening inclined in the same direction as the connecting portion 131 that is the inclined wall, and the lower end portion of the inclined opening is the inclined wall. When the liquid return rib 135 is provided in the connecting portion 134, the contents attached to the outside of the inner cylinder 130 and the contents attached to the edge of the spout 133 are disposed around the connecting portion 134. Further, since the collected contents can flow along the liquid return rib 135 and flow into the filling space M, the liquid return effect can be sufficiently exerted.
また、接続部１３４の頂壁１３４ａを、傾斜壁の傾斜する向きと反対方向に傾く中心側が低い傾斜頂壁とする場合は、接続部１３４周辺に向けて流れてくる内容物に逆向きの流れを与えることができるので、流れの変化によって内容物が溜まりにくくなり、液戻し効果が一層有効に発揮できる。 Further, when the top wall 134a of the connecting portion 134 is an inclined top wall whose center side is inclined in the direction opposite to the inclined direction of the inclined wall, the flow is opposite to the contents flowing toward the periphery of the connecting portion 134. Therefore, the contents hardly accumulate due to a change in flow, and the liquid return effect can be more effectively exhibited.
本発明によれば、引きちぎりタイプの注出栓に関し、注出中に内容物の流れが乱れることなく所期した通りに注出できる上、注出後は液切れが良好であって、しかも引きちぎりにて外筒を破断する際の液だれが起きにくい、使い勝手のよい注出栓を提供することができる。 According to the present invention, the tear-off type pouring tap can be poured out as expected without disturbing the flow of the contents during pouring, and after the pouring, the liquid is well drained, and It is possible to provide an easy-to-use pouring plug in which dripping does not occur when the outer cylinder is broken by tearing.
