特開２０１４－８０２１８号公報Japanese Unexamined Patent Publication No. 2014-80218

特許文献１のスパウトでは、可動部材において複数の通気孔が周方向に間隔を設けて形成され、その内周側に注出筒が配置されている。詰め替え容器から供給される液体と入れ替わりに被詰め替え容器から排出される空気は、通気孔を通じて注出筒の外側から外部に放出される。このため、詰め替え容器が液体の排出に応じて容積を減少しないと、詰め替え容器の内部に負圧が発生し、液体が注出しにくくなる問題がある。 In the spout of Patent Document 1, a plurality of ventilation holes are formed in the movable member at intervals in the circumferential direction, and the pouring cylinder is arranged on the inner peripheral side thereof. The air discharged from the refill container in place of the liquid supplied from the refill container is discharged from the outside of the pouring cylinder to the outside through the ventilation holes. Therefore, if the volume of the refill container is not reduced according to the discharge of the liquid, a negative pressure is generated inside the refill container, and there is a problem that it becomes difficult to pour the liquid.

本発明は、上記事情に鑑みてなされたものであり、液体等の内容物が注出しやすい注出用スパウト及び注出用スパウト付き容器を提供することを課題とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a spout for pouring and a container with a spout for pouring, in which contents such as liquid can be easily poured.

前記課題を解決するため、本発明は、注出筒部を備えるスパウト本体と、前記注出筒部の軸線方向に沿って移動が可能な可動部材とを備え、前記注出筒部は、前記軸線方向に沿って内容物流路を開口したスリットを有し、前記可動部材は、前記スリットにおいて前記内容物流路を閉止する閉止部と、前記注出筒部の内側で前記軸線方向に沿って延びる空気流路を有する管状部と、を有し、前記空気流路は、基端側において前記軸線方向から側方に開口した空気出口を有し、前記スパウト本体は、前記空気出口を覆う筒状の被覆部を有し、前記可動部材を、前記注出筒部に対して先端側から基端側に移動させることにより、前記閉止部が前記スリットの先端側から退避して前記内容物流路が開口し、かつ、前記空気出口が前記被覆部の外側に開口することを特徴とする注出用スパウトを提供する。 In order to solve the above-mentioned problems, the present invention includes a spout main body provided with a dispensing cylinder portion and a movable member capable of moving along the axial direction of the dispensing cylinder portion, and the dispensing cylinder portion is described as described above. The movable member has a slit that opens the content flow path along the axial direction, and the movable member extends along the axial direction inside the pouring cylinder portion and a closing portion that closes the content flow path in the slit. It has a tubular portion having an air flow path, the air flow path has an air outlet that opens laterally from the axial direction on the proximal end side, and the spout body has a tubular shape that covers the air outlet. By moving the movable member from the tip end side to the base end side with respect to the pouring cylinder portion, the closing portion is retracted from the tip end side of the slit, and the content flow path is opened. Provided is a spout for pouring, which is open and the air outlet opens to the outside of the covering portion.

前記可動部材は、前記注出筒部に対して先端側から基端側に移動させたときに、前記スパウト本体に係合する係合部を有してもよい。
前記可動部材は、前記閉止部が前記スリットを閉止する閉止位置と、前記注出筒部に対して先端側から基端側に移動させて前記内容物流路が開口する開放位置との間で、相互に切り替え可能であってもよい。
前記スパウト本体は、前記可動部材を前記軸線方向のスライド移動に案内する案内部を有してもよい。 The movable member may have an engaging portion that engages with the spout body when moved from the distal end side to the proximal end side with respect to the dispensing cylinder portion.
The movable member is located between a closing position where the closing portion closes the slit and an open position where the content flow path is opened by moving the movable member from the tip end side to the base end side with respect to the pouring cylinder portion. It may be switchable between each other.
The spout body may have a guide portion that guides the movable member to slide movement in the axial direction.

前記注出用スパウトは、前記注出筒部の先端側を覆うキャップを備え、前記キャップが前記可動部材の先端側から基端側への移動を阻止してもよい。
前記スパウト本体は、内容物を収容する本体容器に対する取付部を有し、前記注出筒部は前記取付部から先端側に突出していてもよい。
また、本発明は、前記注出用スパウトと、内容物を収容する胴部とを備えることを特徴とする注出用スパウト付き容器を提供する。 The dispensing spout may include a cap that covers the distal end side of the dispensing cylinder portion, and the cap may prevent the movable member from moving from the distal end side to the proximal end side.
The spout main body has a mounting portion for a main body container for accommodating the contents, and the dispensing cylinder portion may protrude from the mounting portion toward the tip end side.
The present invention also provides a container with a spout for pouring, which comprises the spout for pouring and a body for accommodating the contents.

本発明によれば、注出筒部の内側で延びる空気流路の出口である空気出口が側方に開口しているので、閉止位置では内容物流路と共に空気出口が閉止される。また、可動部材を先端側の閉止位置から基端側の開放位置に移動させることで、内容物流路が外部に開口すると共に、空気出口が本体容器内に開口する。内容物流路と空気流路は管状部及び被覆部により区画されるので、液体等の内容物が注出しやすくなる。 According to the present invention, since the air outlet, which is the outlet of the air flow path extending inside the pouring cylinder portion, is opened laterally, the air outlet is closed together with the content flow path at the closed position. Further, by moving the movable member from the closed position on the distal end side to the open position on the proximal end side, the content flow path opens to the outside and the air outlet opens into the main body container. Since the content flow path and the air flow path are partitioned by the tubular portion and the covering portion, the contents such as liquid can be easily poured out.

FIG. 1 shows a state in which the cap 40 is attached to the pouring spout 10. FIG. 2 shows the state of the pouring spout 10 in the closed position. FIG. 3 shows the state of the pouring spout 10 in the open position. 4 and 5 show cross-sectional views of the container 11 with a spout for pouring at the closed position. 6 and 7 of the container with a spout for pouring 11 show a cross-sectional view in an open position.

図１から図３に示すように、実施形態の注出用スパウト１０は、注出筒部２３を備えるスパウト本体２０と、注出筒部２３の先端側から基端側に移動が可能な可動部材３０と、を備えている。さらに、実施形態の注出用スパウト１０は、注出筒部２３の先端部を覆うキャップ４０を備えている。 As shown in FIGS. 1 to 3, the dispensing spout 10 of the embodiment has a spout main body 20 provided with a dispensing cylinder portion 23 and a movable position capable of moving from the tip end side to the base end side of the dispensing cylinder portion 23. A member 30 is provided. Further, the dispensing spout 10 of the embodiment includes a cap 40 that covers the tip end portion of the dispensing cylinder portion 23.

なお、本明細書において、先端側とは、注出筒部２３の中心軸線に沿った両方向のうち、胴部１４から注出用スパウト１０に向かう側である。また、基端側とは、前記中心軸線に沿って注出用スパウト１０から胴部１４に向かう側である。また、以下の説明において、注出筒部２３の中心軸線に対する径方向及び周方向を、それぞれ単に径方向及び周方向という場合がある。すなわち、径方向とは、前記中心軸線に直交する方向である。また、周方向とは、前記中心軸線の周りを取り囲む方向である。また、前記中心軸線に沿った方向を、軸線方向という場合がある。 In the present specification, the tip side is the side from the body portion 14 toward the dispensing spout 10 in both directions along the central axis of the dispensing cylinder portion 23. The base end side is the side from the pouring spout 10 toward the body portion 14 along the central axis. Further, in the following description, the radial direction and the circumferential direction of the dispensing cylinder portion 23 with respect to the central axis may be simply referred to as the radial direction and the circumferential direction, respectively. That is, the radial direction is a direction orthogonal to the central axis. Further, the circumferential direction is a direction surrounding the central axis. Further, the direction along the central axis may be referred to as an axis direction.

図４から図７では、注出用スパウト１０が取り付けられる本体容器１２の一部を合わせて図示する。注出用スパウト付き容器１１は、本体容器１２の口部１３に注出用スパウト１０を装着して構成されている。本体容器１２は、内容物を収容する胴部１４を有する。胴部１４の下方には、底部（図示せず）を有してもよい。本体容器１２は、自立性を有してもよく、また、平袋のように自立性を有しない容器であってもよい。 In FIGS. 4 to 7, a part of the main body container 12 to which the spout for dispensing 10 is attached is also shown. The container 11 with a spout for pouring is configured by mounting the spout 10 for pouring on the mouth 13 of the main body container 12. The main body container 12 has a body portion 14 for accommodating the contents. A bottom portion (not shown) may be provided below the body portion 14. The main body container 12 may be self-supporting, or may be a non-self-supporting container such as a flat bag.

スパウト本体２０は、概略として、本体容器１２に対する取付部２１と、取付部２１から先端側に突出した注出筒部２３とを有する。
また、可動部材３０は、概略として、注出筒部２３に装着される基部３１と、取付部２１に係合される係合部３２とを有する。 The spout main body 20 generally has a mounting portion 21 for the main body container 12 and a dispensing cylinder portion 23 projecting from the mounting portion 21 toward the tip end side.
Further, the movable member 30 generally has a base portion 31 mounted on the dispensing cylinder portion 23 and an engaging portion 32 engaged with the mounting portion 21.

図１に示すように、キャップ４０は、概略として、注出筒部２３に装着される天部４１と、取付部２１及び基部３１の間に係止される係止部４２とを有する。図示例の天部４１は円形であるが、四角形等の多角形、楕円形等、種々の形状に設計することが可能である。天部４１の形状、構造等は、注出筒部２３の先端側に適合すればよく、特に限定されない。 As shown in FIG. 1, the cap 40 generally has a top portion 41 mounted on the dispensing cylinder portion 23 and a locking portion 42 locked between the mounting portion 21 and the base portion 31. Although the top 41 in the illustrated example is circular, it can be designed into various shapes such as a polygon such as a quadrangle and an ellipse. The shape, structure, and the like of the top portion 41 may be adapted to the tip end side of the dispensing cylinder portion 23, and are not particularly limited.

係止部４２は、可動部材３０の基部３１と取付部２１の上縁部２１ｃとの間に形成された切欠部３２ｃに係止されている。キャップ４０の装着により、可動部材３０が先端側から基端側に移動することが阻止されている。図示例のキャップ４０は、周方向の２箇所に対向して係止部４２を有し、径方向の内側から外側に向けて弾性変形させることにより、取付部２１に対する係止部４２の係止が解除される。キャップ４０をスパウト本体２０に固定するための構造は、アーム状の部材の弾性変形を用いた係止に限定されず、例えば、取付部２１の外周全面に対してキャップ４０を嵌合してもよい。 The locking portion 42 is locked to the notch portion 32c formed between the base portion 31 of the movable member 30 and the upper edge portion 21c of the mounting portion 21. By attaching the cap 40, the movable member 30 is prevented from moving from the tip end side to the base end side. The cap 40 of the illustrated example has locking portions 42 facing two points in the circumferential direction, and is elastically deformed from the inside to the outside in the radial direction to lock the locking portion 42 to the mounting portion 21. Is released. The structure for fixing the cap 40 to the spout body 20 is not limited to locking using elastic deformation of the arm-shaped member, and for example, even if the cap 40 is fitted to the entire outer periphery of the mounting portion 21. good.

図示例のスパウト本体２０の場合、取付部２１の上縁部２１ｃが、先端側に向かってなだらかに肉厚を減少させたリブ状に形成されている。このため、上縁部２１ｃの外側からキャップ４０の係止部４２を挟み込んだとき、上縁部２１ｃが内側に変形しにくい。また、係止部４２の係止を解除するとき、上縁部２１ｃの外側の曲面に沿って、係止部４２の内側に手指を掛けやすい。 In the case of the spout main body 20 of the illustrated example, the upper edge portion 21c of the mounting portion 21 is formed in a rib shape whose wall thickness is gently reduced toward the tip end side. Therefore, when the locking portion 42 of the cap 40 is sandwiched from the outside of the upper edge portion 21c, the upper edge portion 21c is less likely to be deformed inward. Further, when releasing the locking of the locking portion 42, it is easy to put a finger on the inside of the locking portion 42 along the curved surface on the outer side of the upper edge portion 21c.

図２に示すように、注出用スパウト１０からキャップ４０を取り外すと、可動部材３０は、注出筒部２３に対して先端側から基端側に移動させることが可能になる。取付部２１の側面に形成されている把持凹所２１ｂは、本体容器１２に対する注出用スパウト１０の取り付け、キャップ４０の取り外し等に際して、注出用スパウト１０を把持するとき、必要に応じて使用することができる。図示例の可動部材３０の場合は、周方向の２箇所で、切欠部３２ｃとは異なる側に係合部３２が形成されている。 As shown in FIG. 2, when the cap 40 is removed from the pouring spout 10, the movable member 30 can be moved from the tip end side to the base end side with respect to the pouring cylinder portion 23. The gripping recess 21b formed on the side surface of the mounting portion 21 is used as necessary when gripping the pouring spout 10 when mounting the pouring spout 10 to the main body container 12, removing the cap 40, or the like. can do. In the case of the movable member 30 of the illustrated example, the engaging portions 32 are formed on the sides different from the notched portions 32c at two points in the circumferential direction.

取付部２１の側面には、可動部材３０の移動の際に、係合部３２が進入可能なスライド凹部２２が形成されている。係合部３２の内面に形成された係合凸部３２ａ（図５、図７を参照）は、スライド凹部２２内に形成された係合凹部２２ａに係合することが可能である。スライド凹部２２は、係合部３２に対して軸線方向に形成されており、可動部材３０が軸線方向にスライド移動するように案内する案内部となっている。 A slide recess 22 is formed on the side surface of the mounting portion 21 so that the engaging portion 32 can enter when the movable member 30 moves. The engaging convex portion 32a (see FIGS. 5 and 7) formed on the inner surface of the engaging portion 32 can engage with the engaging concave portion 22a formed in the slide concave portion 22. The slide recess 22 is formed in the axial direction with respect to the engaging portion 32, and is a guide portion that guides the movable member 30 to slide and move in the axial direction.

基部３１と係合部３２との間に形成された補強リブ３２ｂは、可動部材３０の移動の際に、挿入溝２２ｂに挿入される。補強リブ３２ｂは、略均一の肉厚を有する板状であってもよい。挿入溝２２ｂに補強リブ３２ｂが挿入される深さは、可動部材３０が基端側に移動され得る限度に応じて調整されてもよい。挿入溝２２ｂは、補強リブ３２ｂに対して軸線方向に形成されており、可動部材３０が軸線方向にスライド移動するように案内する案内部となっている。 The reinforcing rib 32b formed between the base portion 31 and the engaging portion 32 is inserted into the insertion groove 22b when the movable member 30 moves. The reinforcing rib 32b may have a plate shape having a substantially uniform wall thickness. The depth at which the reinforcing rib 32b is inserted into the insertion groove 22b may be adjusted according to the limit in which the movable member 30 can be moved toward the proximal end side. The insertion groove 22b is formed in the axial direction with respect to the reinforcing rib 32b, and is a guide portion that guides the movable member 30 to slide and move in the axial direction.

注出筒部２３は、取付部２１から先端側に突出した形状である。これにより、注出筒部２３の径方向の外側には、取付部２１上で可動部材３０を機能させる空間が整然と確保される。図示例の注出筒部２３は、スリット２６を除く全体形状が略円筒形状であるが、注出筒部２３の形状は特に限定されず、三角筒状、四角筒状等の角筒状、楕円筒状等にしてもよい。 The dispensing cylinder portion 23 has a shape protruding from the mounting portion 21 toward the tip end side. As a result, a space for the movable member 30 to function on the mounting portion 21 is systematically secured on the outer side of the dispensing cylinder portion 23 in the radial direction. The overall shape of the dispenser cylinder portion 23 in the illustrated example except for the slit 26 is substantially cylindrical, but the shape of the dispenser cylinder portion 23 is not particularly limited, and the shape of the dispenser cylinder portion 23 is not particularly limited to a triangular cylinder shape, a square cylinder shape, or the like. It may be in the shape of an elliptical cylinder or the like.

図２及び図３に示すように、注出筒部２３は、軸線方向に沿って内容物流路２４を開口したスリット２６を有する。また、可動部材３０は、スリット２６において内容物流路２４を閉止する閉止部３３を有する。図示例の注出筒部２３は、周方向の２箇所にスリット２６を有し、また、周方向でスリット２６の位置とは異なる２箇所に内容物流路２４を有する。 As shown in FIGS. 2 and 3, the dispensing cylinder portion 23 has a slit 26 that opens the content flow path 24 along the axial direction. Further, the movable member 30 has a closing portion 33 that closes the content flow path 24 in the slit 26. The dispensing cylinder portion 23 of the illustrated example has slits 26 at two locations in the circumferential direction, and has content flow paths 24 at two locations different from the positions of the slits 26 in the circumferential direction.

スリット２６の開口形状は、先端側から見た平面視で、略Ｈ字状に形成されている。なお、図示例のスリット２６は、注出筒部２３を２つ割り状に分割した形状となっている。スリット２６は、少なくとも、注出筒部２３の径方向の内側から外側に向けて開口した箇所を有する。注出筒部２３の先端部においてスリット２６が開口していなくても、スリット２６から内容物を注出することは可能である。 The opening shape of the slit 26 is formed in a substantially H shape in a plan view seen from the tip side. The slit 26 in the illustrated example has a shape in which the dispensing cylinder portion 23 is divided into two parts. The slit 26 has at least a portion that opens from the inside to the outside in the radial direction of the dispensing cylinder portion 23. It is possible to dispense the contents from the slit 26 even if the slit 26 is not opened at the tip of the dispensing cylinder portion 23.

スリット２６が、注出筒部２３の側部に加えて、中心軸線付近においても開口している。このため、中心軸線を介して対向して２箇所の内容物流路２４から注出される内容物は、中心軸線付近で合流することができる。また、可動部材３０を先端側からスパウト本体２０に取り付ける際、スリット２６の先端側から閉止部３３を挿入することができる。なお、スリット２６の形状は特に限定されず、注出筒部２３の周方向の１箇所以上で任意の位置に配置することができる。 The slit 26 is open in the vicinity of the central axis in addition to the side portion of the dispensing cylinder portion 23. Therefore, the contents discharged from the two contents flow paths 24 facing each other via the central axis can merge in the vicinity of the central axis. Further, when the movable member 30 is attached to the spout body 20 from the tip side, the closing portion 33 can be inserted from the tip side of the slit 26. The shape of the slit 26 is not particularly limited, and the slit 26 can be arranged at an arbitrary position at one or more locations in the circumferential direction of the dispensing cylinder portion 23.

可動部材３０は、注出筒部２３の内側に管状部３４を有する。管状部３４の内部には、軸線方向に沿って延びる空気流路３５が形成されている。図示例の可動部材３０は、空気流路３５を有する管状部３４を、中心軸線に沿った内容物流路２４の両側２箇所に備えている。すなわち、上述した略Ｈ字状のスリット２６における左右両側が、管状部３４の配置される領域となっている。 The movable member 30 has a tubular portion 34 inside the dispensing tube portion 23. Inside the tubular portion 34, an air flow path 35 extending along the axial direction is formed. The movable member 30 of the illustrated example is provided with a tubular portion 34 having an air flow path 35 at two locations on both sides of the content flow path 24 along the central axis. That is, the left and right sides of the substantially H-shaped slit 26 described above are regions where the tubular portion 34 is arranged.

なお、閉止部３３と管状部３４との範囲は、必ずしも厳密に区別する必要はない。軸線方向で可動部材３０がスリット２６の位置と重なり合う、管状部３４の先端側の部分のうち、空気流路３５を囲む内部を除く外周部は、スリット２６の側部を閉止する閉止部３３として機能することができる。すなわち、可動部材３０に含まれる同一の部分が、閉止部３３の機能と管状部３４の機能とを兼ねてもよい。 It should be noted that the range of the closing portion 33 and the tubular portion 34 does not necessarily have to be strictly distinguished. Of the portion on the tip end side of the tubular portion 34 where the movable member 30 overlaps the position of the slit 26 in the axial direction, the outer peripheral portion excluding the inside surrounding the air flow path 35 is used as a closing portion 33 for closing the side portion of the slit 26. Can function. That is, the same portion included in the movable member 30 may have both the function of the closing portion 33 and the function of the tubular portion 34.

注出筒部２３のスリット２６側の面には、可動部材３０の移動を案内するように、軸線方向に沿った案内溝２５が形成されている。案内溝２５は、管状部３４を挟み込むように対をなして配置されている。すなわち、２箇所の管状部３４に対して各２箇所、合計４箇所に案内溝２５が設けられている。 A guide groove 25 along the axial direction is formed on the surface of the dispensing cylinder portion 23 on the slit 26 side so as to guide the movement of the movable member 30. The guide grooves 25 are arranged in pairs so as to sandwich the tubular portion 34. That is, guide grooves 25 are provided at two locations for each of the two tubular portions 34, for a total of four locations.

案内溝２５は、管状部３４に対して軸線方向に形成されており、可動部材３０が軸線方向にスライド移動するように案内する案内部となっている。これにより、可動部材３０は、軸線方向に沿った変位に際して、左右のいずれにも変位が抑制されている。すなわち、可動部材３０の変位は、軸線方向の変位を主とし、径方向又は周方向の変位が起こりにくくなっている。 The guide groove 25 is formed in the axial direction with respect to the tubular portion 34, and is a guide portion that guides the movable member 30 so as to slide and move in the axial direction. As a result, the movable member 30 is restrained from being displaced to either the left or right when it is displaced along the axial direction. That is, the displacement of the movable member 30 is mainly the displacement in the axial direction, and the displacement in the radial direction or the circumferential direction is less likely to occur.

図３及び図４に示すように、注出筒部２３の先端側には、可動部材３０の制動凹部３３ａに結合可能な制動凸部２３ａが形成されている。制動凸部２３ａは、注出筒部２３の頂面部２３ｂから径方向内側に突出している。また、制動凹部３３ａは、閉止部３３の先端側で、頂面部２３ｂに接する位置に形成されている。制動凸部２３ａ及び制動凹部３３ａの結合力に抗して、可動部材３０を先端側から基端側に移動させる外力が作用すると、注出筒部２３及び閉止部３３の弾性変形等により、制動凸部２３ａ及び制動凹部３３ａの結合が解除されて、可動部材３０が移動可能になる。 As shown in FIGS. 3 and 4, a braking convex portion 23a that can be coupled to the braking concave portion 33a of the movable member 30 is formed on the tip end side of the dispensing cylinder portion 23. The braking convex portion 23a projects radially inward from the top surface portion 23b of the dispensing cylinder portion 23. Further, the braking recess 33a is formed at a position on the tip end side of the closing portion 33 and in contact with the top surface portion 23b. When an external force that moves the movable member 30 from the tip end side to the base end side acts against the coupling force of the braking convex portion 23a and the braking concave portion 33a, braking is performed due to elastic deformation of the dispensing cylinder portion 23 and the closing portion 33. The coupling between the convex portion 23a and the braking concave portion 33a is released, and the movable member 30 becomes movable.

なお、図示例の制動凸部２３ａ及び制動凹部３３ａは、注出筒部２３の内側で、スリット２６に面する位置に設けられているが、注出筒部２３の外側など、他の位置に設けられてもよい。図示例の場合、可動部材３０が移動する際、閉止部３３がスリット２６内で変位しても、制動凹部３３ａが凹んでいるため、閉止部３３がスリット２６に干渉することなく、円滑な移動が可能である。例えば、スリット２６の開口幅を基端側で広くする場合には、可動部材３０側に制動凸部を設け、スパウト本体側に制動凹部を設けてもよい。 The braking convex portion 23a and the braking concave portion 33a in the illustrated example are provided at positions facing the slit 26 inside the dispensing cylinder portion 23, but at other positions such as outside the dispensing cylinder portion 23. It may be provided. In the case of the illustrated example, when the movable member 30 moves, even if the closing portion 33 is displaced in the slit 26, the braking recess 33a is recessed, so that the closing portion 33 does not interfere with the slit 26 and moves smoothly. Is possible. For example, when the opening width of the slit 26 is widened on the proximal end side, a braking convex portion may be provided on the movable member 30 side, and a braking concave portion may be provided on the spout main body side.

図４に示すように、実施形態の注出用スパウト１０は、スパウト本体２０と本体容器１２とが別部材から構成されている。具体的には、本体容器１２の充填口又は注出口となる口部１３の周囲に、取付部２１から基端側に、取付筒部２８が突出されている。取付筒部２８の内面のねじ部２８ａと、口部１３の外面のねじ部１３ａとの結合により、スパウト本体２０が本体容器１２に固定される。 As shown in FIG. 4, in the dispensing spout 10 of the embodiment, the spout main body 20 and the main body container 12 are composed of separate members. Specifically, the mounting cylinder portion 28 projects from the mounting portion 21 to the base end side around the mouth portion 13 that serves as the filling port or the spout of the main body container 12. The spout main body 20 is fixed to the main body container 12 by the coupling between the threaded portion 28a on the inner surface of the mounting cylinder portion 28 and the threaded portion 13a on the outer surface of the mouth portion 13.

取付部２１の内側は、本体容器１２の肩部１５との干渉を避けるように、取付凹所２１ａが形成されている。肩部１５は、胴部１４から口部１３に向けて先細りとなる部分である。取付筒部２８は、取付凹所２１ａ内に配置されている。取付筒部２８の位置を口部１３に合わせて、ねじ部１３ａ，２８ａを結合することにより、スパウト本体２０を本体容器１２に取り付けることができる。また、ねじ部１３ａ，２８ａを取付のときとは反対側に回転させることにより、スパウト本体２０を本体容器１２から取り外すことができる。 Inside the mounting portion 21, a mounting recess 21a is formed so as to avoid interference with the shoulder portion 15 of the main body container 12. The shoulder portion 15 is a portion that tapers from the body portion 14 toward the mouth portion 13. The mounting cylinder portion 28 is arranged in the mounting recess 21a. The spout main body 20 can be attached to the main body container 12 by aligning the position of the mounting cylinder portion 28 with the mouth portion 13 and connecting the screw portions 13a and 28a. Further, the spout main body 20 can be removed from the main body container 12 by rotating the screw portions 13a and 28a on the opposite side to those at the time of mounting.

本体容器１２において、内容物の収容部を含む胴部１４の構成は、特に限定されないが、例えば、ボトル容器、パウチ容器、チューブ容器等が挙げられる。本体容器１２がボトル容器などの成形容器である場合は、成形容器の一部として、スパウト本体２０が本体容器１２に一体化されていてもよい。本体容器１２がボトル容器などのリジッド（剛性）容器又は半剛性容器からなる場合には、肉厚の樹脂成形容器、金属容器、ガラス容器等によって本体容器１２を構成することも可能である。 In the main body container 12, the configuration of the body portion 14 including the content accommodating portion is not particularly limited, and examples thereof include a bottle container, a pouch container, and a tube container. When the main body container 12 is a molded container such as a bottle container, the spout main body 20 may be integrated with the main body container 12 as a part of the molded container. When the main body container 12 is made of a rigid (rigid) container such as a bottle container or a semi-rigid container, the main body container 12 can be configured by a thick resin molded container, a metal container, a glass container, or the like.

本体容器１２の構造等に応じて、スパウト本体２０は、本体容器１２の口部１３、胴部１４、肩部１５のいずれに取り付けることも可能である。本体容器１２に対する取付部２１の取付け方法は特に限定されず、嵌合、係合、接着等が挙げられる。接着は、スパウト本体２０又は本体容器１２の材料を溶融させる等による接着でもよく、接着剤を付与した接着でもよい。 Depending on the structure of the main body container 12, the spout main body 20 can be attached to any of the mouth portion 13, the body portion 14, and the shoulder portion 15 of the main body container 12. The method of attaching the attachment portion 21 to the main body container 12 is not particularly limited, and examples thereof include fitting, engagement, and adhesion. Adhesion may be performed by melting the material of the spout body 20 or the body container 12, or may be bonded with an adhesive.

パウチ容器に取付部２１を接合する場合は、取付部２１の外面又は内面にフィルム、シート等のパウチ部材を接合してもよい。パウチ部材は、少なくとも片面に熱可塑性樹脂からなるシーラント層、接着層を有することで、パウチ部材同士の接合に食わせて、パウチ部材とスパウト本体との接合を行うことができる。パウチ容器としては、スタンディングパウチ、側面又は底面にフィルムの折り込みを有するガゼット容器などが挙げられる。 When the mounting portion 21 is joined to the pouch container, a pouch member such as a film or a sheet may be joined to the outer surface or the inner surface of the mounting portion 21. By having the sealant layer and the adhesive layer made of a thermoplastic resin on at least one side of the pouch member, the pouch member and the spout body can be joined by feeding the pouch members together. Examples of the pouch container include a standing pouch, a gusset container having a film fold on the side surface or the bottom surface, and the like.

ボトル容器などの成形容器を成形する材料としては、熱可塑性樹脂、熱硬化性樹脂等の各種合成樹脂が挙げられる。パウチ容器、チューブ容器、ボトル容器などの容器が、金属、紙、無機化合物、有機化合物等の樹脂以外の材質からなる層を含んでもよい。被注出容器（図示せず）は、内容物を注出する相手側となる容器である。本体容器１２は、被注出容器に内容物を移し替えるための詰め替え容器としてもよい。被注出容器としては、被詰め替え容器、計量容器、その他の各種の容器が挙げられる。注出用スパウト１０は、使い捨てでもよく、同種の本体容器１２に付け替えて、繰り返し使用してもよい。 Examples of the material for molding a molding container such as a bottle container include various synthetic resins such as a thermoplastic resin and a thermosetting resin. A container such as a pouch container, a tube container, or a bottle container may include a layer made of a material other than resin such as metal, paper, an inorganic compound, and an organic compound. The dispensed container (not shown) is the container on which the contents are dispensed. The main body container 12 may be a refill container for transferring the contents to the dispensed container. Examples of the dispensed container include a refillable container, a measuring container, and various other containers. The pouring spout 10 may be disposable or may be replaced with the same type of main body container 12 and used repeatedly.

内容物としては特に限定されないが、液体、粉体、粒体等の流体を採用できる。内容物の種類としては、特に限定されず、飲料品、食料品、調味料、化粧品、医薬品、洗剤、接着剤、家庭用品、工業製品などが挙げられる。液体の内容物としては、飲料、調味液、洗剤、薬剤などが挙げられる。粉体又は粒体の内容物には、塩、砂糖、胡椒、顆粒状調味料、粉末洗剤などを挙げることができる。 The content is not particularly limited, but a fluid such as a liquid, powder, or granule can be adopted. The types of contents are not particularly limited, and examples thereof include beverages, foods, seasonings, cosmetics, pharmaceuticals, detergents, adhesives, household products, and industrial products. Examples of the liquid contents include beverages, seasonings, detergents, chemicals and the like. Examples of the contents of the powder or granules include salt, sugar, pepper, granular seasoning, powder detergent and the like.

注出用スパウト１０を構成するスパウト本体２０、可動部材３０及びキャップ４０は、例えば、熱可塑性樹脂、熱硬化性樹脂等の各種合成樹脂から成形することができる。実施形態の注出用スパウト１０は、スパウト本体２０及び可動部材３０をそれぞれ一体成形品として２部材、キャップ４０を含めると３部材から構成することができる。 The spout body 20, the movable member 30, and the cap 40 constituting the pouring spout 10 can be molded from various synthetic resins such as a thermoplastic resin and a thermosetting resin, for example. The pouring spout 10 of the embodiment can be composed of two members, each of which is an integrally molded product of the spout body 20 and the movable member 30, and three members including the cap 40.

スパウト本体２０を２以上の部品から組み立てて構成してもよく、可動部材３０を２以上の部品から組み立てて構成してもよく、キャップ４０を２以上の部品から組み立てて構成してもよい。また、スパウト本体２０、可動部材３０又はキャップ４０からなる３部材のうち、少なくとも２以上の部材を、紐状の連結部などを介して連結することにより、連結部の端部に各部材が構成された一体成形品とすることも可能である。 The spout body 20 may be assembled from two or more parts, the movable member 30 may be assembled from two or more parts, or the cap 40 may be assembled from two or more parts. Further, by connecting at least two or more members out of the three members consisting of the spout body 20, the movable member 30, or the cap 40 via a string-shaped connecting portion or the like, each member is formed at the end of the connecting portion. It is also possible to make an integrally molded product.

図５に示すように、空気流路３５の入口である空気入口３５ａは、管状部３４の軸線方向における先端部３４ａに開口している。空気流路３５は、管状部３４の内部において、軸線方向に沿って基端側に延びている。空気流路３５の基端側では、空気流路３５が軸線方向から側方に屈曲し、空気出口３５ｂが管状部３４の側面に開口している。空気出口３５ｂは、空気流路３５の出口である。管状部３４の基端部３４ｂは、空気流路３５が開口されることなく、閉鎖されている。 As shown in FIG. 5, the air inlet 35a, which is the inlet of the air flow path 35, is open to the tip portion 34a in the axial direction of the tubular portion 34. The air flow path 35 extends toward the proximal end side along the axial direction inside the tubular portion 34. On the base end side of the air flow path 35, the air flow path 35 bends laterally from the axial direction, and the air outlet 35b opens on the side surface of the tubular portion 34. The air outlet 35b is an outlet of the air flow path 35. The base end portion 34b of the tubular portion 34 is closed without opening the air flow path 35.

スパウト本体２０は、空気出口３５ｂを覆う筒状の被覆部２７を有する。被覆部２７は、取付部２１において、取付筒部２８の内側から基端側に突出している。被覆部２７は、先端側に先端開口部２７ａが開口し、基端側に基端開口部２７ｂが開口したトンネル状の内壁部２７ｃを有する。被覆部２７は、管状部３４に対して軸線方向に形成されており、可動部材３０が軸線方向にスライド移動するように案内する案内部となっている。 The spout body 20 has a tubular covering portion 27 that covers the air outlet 35b. The covering portion 27 projects from the inside of the mounting cylinder portion 28 toward the proximal end side in the mounting portion 21. The covering portion 27 has a tunnel-shaped inner wall portion 27c in which the tip opening portion 27a is opened on the tip end side and the proximal end opening portion 27b is opened on the proximal end side. The covering portion 27 is formed in the axial direction with respect to the tubular portion 34, and is a guide portion that guides the movable member 30 to slide and move in the axial direction.

スパウト本体２０に可動部材３０を取り付けるときは、管状部３４を基端開口部２７ｂに挿入し、内壁部２７ｃに沿って基端側に移動させることで、管状部３４が取付部２１に支持される。閉止位置において、空気出口３５ｂは、基端開口部２７ｂに露出されることなく、内壁部２７ｃに接して閉鎖される。 When attaching the movable member 30 to the spout body 20, the tubular portion 34 is supported by the attachment portion 21 by inserting the tubular portion 34 into the proximal end opening 27b and moving it toward the proximal end side along the inner wall portion 27c. To. At the closing position, the air outlet 35b is closed in contact with the inner wall portion 27c without being exposed to the proximal end opening 27b.

図４に示すように、閉止部３３がスリット２６を閉止する閉止位置において、上述した制動凸部２３ａ及び制動凹部３３ａ等の作用により、可動部材３０の移動は、一旦停止される。閉止位置におけるスパウト本体２０と可動部材３０との位置関係は、上述したように制動凸部２３ａ及び制動凹部３３ａの結合を解除する程度の外力が作用するまでは安定している。このため、本体容器１２の口部１３に注出用スパウト１０を取り付けた後、内容物が胴部１４から注出されるように口部１３を傾け、さらには口部１３を下向きにしても、可動部材３０は閉止位置を維持することができる。 As shown in FIG. 4, at the closing position where the closing portion 33 closes the slit 26, the movement of the movable member 30 is temporarily stopped by the action of the braking convex portion 23a, the braking concave portion 33a, and the like described above. The positional relationship between the spout body 20 and the movable member 30 at the closed position is stable until an external force is applied to the extent that the coupling of the braking convex portion 23a and the braking concave portion 33a is released as described above. Therefore, even if the spout 10 for dispensing is attached to the mouth 13 of the main body container 12, the mouth 13 is tilted so that the contents are discharged from the body 14, and the mouth 13 is turned downward, the mouth 13 may be turned downward. The movable member 30 can maintain the closed position.

本体容器１２から被注出容器に対して、可動部材３０の先端側を押し当てる等すると、閉止位置を超えた移動が可能になり、制動凸部２３ａ及び制動凹部３３ａの結合が解除される。このため、ユーザーが本体容器１２から内容物を取り出そうとするとき、スパウト本体２０又は可動部材３０を手に取って操作しなくても、可動部材３０の移動を開始することが可能である。本体容器１２の口部１３を傾け、又は下向きにした状態でも、注出用スパウト１０が閉止位置にあれば内容物は注出されないため、注出用スパウト１０を被注出容器に容易に接近させることができる。 When the tip end side of the movable member 30 is pressed against the dispensed container from the main body container 12, the movable member 30 can be moved beyond the closed position, and the coupling of the braking convex portion 23a and the braking concave portion 33a is released. Therefore, when the user intends to take out the contents from the main body container 12, it is possible to start the movement of the movable member 30 without having to pick up and operate the spout main body 20 or the movable member 30. Even when the mouth portion 13 of the main body container 12 is tilted or turned downward, the contents are not dispensed if the dispensing spout 10 is in the closed position, so that the dispensing spout 10 can be easily approached to the dispensed container. Can be made to.

図６に示すように、可動部材３０がスパウト本体２０に対して先端側から基端側に移動すると、閉止部３３がスリット２６の先端側から退避して、内容物流路２４が外部に開口した開放位置になる。開放位置では、注出筒部２３の先端側と、閉止部３３の先端側との間で、スリット２６を通じて内容物流路２４が開口される。本体容器１２の口部１３を傾け、又は下向きにした状態で、注出用スパウト１０が開放位置になると、被注出容器に向けて内容物Ｌを注出することができる。本体容器１２が肩部１５を有する場合は、内容物Ｌが肩部１５に沿って、少なくとも中心軸線に対する片側から流れてもよい。 As shown in FIG. 6, when the movable member 30 moves from the tip end side to the base end side with respect to the spout body 20, the closing portion 33 retracts from the tip end side of the slit 26, and the content flow path 24 opens to the outside. It will be in the open position. In the open position, the content flow path 24 is opened through the slit 26 between the tip end side of the dispensing cylinder portion 23 and the tip end side of the closing portion 33. When the dispensing spout 10 is in the open position with the mouth portion 13 of the main body container 12 tilted or downward, the content L can be dispensed toward the dispensing container. When the main body container 12 has the shoulder portion 15, the content L may flow along the shoulder portion 15 from at least one side with respect to the central axis.

図示例の注出用スパウト１０の場合は、注出筒部２３の中心軸線を含む平面に沿ってスリット２６が注出筒部２３を二つ割り状に分割し、注出筒部２３の先端側で頂面部２３ｂが内容物流路２４の断面積を規制している。これにより、スリット２６の両側から内容物流路２４を経由した内容物Ｌの流れは、中心軸線に沿って注出筒部２３の中心付近に集中する傾向を示す。これにより、内容物Ｌの流れが安定になり、被注出容器に対して、より確実に内容物Ｌを注出することができる。 In the case of the spout 10 for pouring in the illustrated example, the slit 26 divides the pouring cylinder 23 into two along a plane including the central axis of the pouring cylinder 23, and the tip side of the pouring cylinder 23 The top surface portion 23b regulates the cross-sectional area of the content flow path 24. As a result, the flow of the contents L from both sides of the slit 26 via the contents flow path 24 tends to be concentrated near the center of the dispensing cylinder portion 23 along the central axis. As a result, the flow of the content L becomes stable, and the content L can be more reliably dispensed to the dispensed container.

図示例では、可動部材３０の閉止部３３は、開放位置においても、内容物流路２４の途中に位置している。閉止部３３の基端側には、Ｖ字状に対向する一対の分流斜面３３ｂが形成されている。これにより、内容物流路２４に閉止部３３が存在しても、内容物Ｌの流れが乱れにくくなる。図示例の分流斜面３３ｂは、中心軸線を含む平面に対して対称的に配置された２つの斜面からなる。分流斜面３３ｂが片流れ状の１つの斜面であってもよく、周方向で放射状に３つ以上の斜面、あるいは円錐状であってもよい。分流斜面３３ｂの突端は丸みを持たせてもよい。 In the illustrated example, the closing portion 33 of the movable member 30 is located in the middle of the content flow path 24 even in the open position. A pair of diversion slopes 33b facing each other in a V shape are formed on the base end side of the closing portion 33. As a result, even if the closing portion 33 is present in the content flow path 24, the flow of the content L is less likely to be disturbed. The diversion slope 33b in the illustrated example consists of two slopes arranged symmetrically with respect to the plane including the central axis. The diversion slope 33b may be one one-sided slope, or may be three or more slopes radially in the circumferential direction, or may be conical. The tip of the diversion slope 33b may be rounded.

また、図７に示すように、開放位置においては、被覆部２７の内壁部２７ｃに沿った管状部３４の変位が進行し、空気出口３５ｂが基端開口部２７ｂを脱する。その結果、空気出口３５ｂが被覆部２７の外側に露出され、本体容器１２内に向けて開口する。これにより、内容物Ｌと入れ替わりに被注出容器から排出された空気Ａが、空気流路３５を通じて本体容器１２に流入する。 Further, as shown in FIG. 7, in the open position, the displacement of the tubular portion 34 along the inner wall portion 27c of the covering portion 27 progresses, and the air outlet 35b escapes from the proximal end opening 27b. As a result, the air outlet 35b is exposed to the outside of the covering portion 27 and opens toward the inside of the main body container 12. As a result, the air A discharged from the dispensed container instead of the content L flows into the main body container 12 through the air flow path 35.

空気流路３５は軸線方向の基端側には開口しておらず、管状部３４の側方に開口しているため、内容物Ｌが空気流路３５に進入することは起こりにくい。また、空気流路３５の断面積に比べて、内容物流路２４の断面積が大きいため、内容物Ｌが空気流路３５に進入することは起こりにくい。さらに、開放位置における空気出口３５ｂの位置が、本体容器１２の肩部１５の位置に比べて、軸線方向で基端側に突出しているため、肩部１５に沿って流れる内容物Ｌが空気出口３５ｂに到達しにくい。 Since the air flow path 35 does not open on the proximal end side in the axial direction but opens on the side of the tubular portion 34, it is unlikely that the content L enters the air flow path 35. Further, since the cross-sectional area of the content flow path 24 is larger than the cross-sectional area of the air flow path 35, it is unlikely that the content L enters the air flow path 35. Further, since the position of the air outlet 35b in the open position protrudes toward the proximal end side in the axial direction as compared with the position of the shoulder portion 15 of the main body container 12, the content L flowing along the shoulder portion 15 is the air outlet. It is difficult to reach 35b.

実施形態の注出用スパウト１０によれば、本体容器１２が内容物Ｌの排出に応じて容積を減じにくい剛性容器又は半剛性容器であっても、内容物Ｌの減少に応じた体積の空気が、被注出容器から本体容器１２内に流入する。これにより、本体容器１２の内外の圧力差が生じにくくなり、本体容器１２から内容物Ｌが円滑に注出される。 According to the pouring spout 10 of the embodiment, even if the main body container 12 is a rigid container or a semi-rigid container whose volume is difficult to decrease according to the discharge of the content L, the volume of air corresponding to the decrease of the content L Flows into the main body container 12 from the dispensed container. As a result, the pressure difference between the inside and outside of the main body container 12 is less likely to occur, and the content L is smoothly poured out from the main body container 12.

上述したように、内容物Ｌの注出は、閉止部３３がスリット２６の先端側から退避した段階から開始される。また、空気Ａの流入は、空気出口３５ｂが被覆部２７の基端開口部２７ｂを超えた段階で開始される。本体容器１２から被注出容器への内容物Ｌの注出と、被注出容器から本体容器１２への空気Ａの流入が略同時期に開始するため、空気Ａの流入量が内容物Ｌの注出量に連動して変化することができる。 As described above, the pouring of the content L is started from the stage where the closing portion 33 is retracted from the tip end side of the slit 26. Further, the inflow of air A is started when the air outlet 35b exceeds the base end opening 27b of the covering portion 27. Since the pouring of the content L from the main body container 12 to the to-out container and the inflow of air A from the to-out container to the main body container 12 start at approximately the same time, the inflow amount of air A is the content L. Can change in conjunction with the amount of pouring.

さらに、注出筒部２３に対して、可動部材３０を先端側から基端側に移動させることにより、可動部材３０の係合凸部３２ａがスパウト本体２０の係合凹部２２ａに係合して、可動部材３０が開放位置に固定される。これにより、開放位置において、被注出容器に対し可動部材３０を接触させ続けなくても、可動部材３０が基端側から先端側に戻ることがなく、開放位置の状態が維持される。 Further, by moving the movable member 30 from the tip end side to the base end side with respect to the dispensing cylinder portion 23, the engaging convex portion 32a of the movable member 30 engages with the engaging concave portion 22a of the spout body 20. , The movable member 30 is fixed in the open position. As a result, even if the movable member 30 is not kept in contact with the dispensed container in the open position, the movable member 30 does not return from the proximal end side to the distal end side, and the open position state is maintained.

しかしながら、実施形態の注出用スパウト１０においても、係合凸部３２ａと係合凹部２２ａとの係合を解除することにより、開放位置から閉止位置へと可動部材３０の位置を戻すことが可能である。また、係合部３２における係合凸部３２ａの係合を省略して、開放位置における可動部材３０の位置を、注出筒部２３の案内溝２５及び被覆部２７の内壁部２７ｃに対する管状部３４の摩擦力等で維持してもよい。これにより、可動部材３０の位置を閉止位置と開放位置との間で相互に切り替え可能となる。 However, even in the dispensing spout 10 of the embodiment, the position of the movable member 30 can be returned from the open position to the closed position by disengaging the engaging convex portion 32a and the engaging concave portion 22a. Is. Further, the engagement of the engaging convex portion 32a in the engaging portion 32 is omitted, and the position of the movable member 30 in the open position is set to the tubular portion with respect to the guide groove 25 of the dispensing cylinder portion 23 and the inner wall portion 27c of the covering portion 27. It may be maintained by the frictional force of 34 or the like. This makes it possible to switch the position of the movable member 30 between the closed position and the open position.

例えば、可動部材３０が被注出容器に接触している間だけ開放位置が維持され、可動部材３０が被注出容器から離れたとき、可動部材３０が閉止位置に向けて基端側から先端側への移動を開始する構成とすることも可能である。例えば、内容物Ｌが内容物流路２４内で流れ落ちる間で頂面部２３ｂに生じる作用により、可動部材３０が先端側に向けて変位する運動を得てもよい。また、バネ等の付勢により、可動部材３０が被注出容器から離れたときに、可動部材３０が先端側に向けて変位してもよい。 For example, the open position is maintained only while the movable member 30 is in contact with the dispensed container, and when the movable member 30 is separated from the dispensed container, the movable member 30 moves from the proximal end side toward the closing position. It is also possible to configure it to start moving to the side. For example, the movable member 30 may be displaced toward the tip end side due to the action generated on the top surface portion 23b while the content L flows down in the content flow path 24. Further, when the movable member 30 is separated from the dispensed container by the urging of a spring or the like, the movable member 30 may be displaced toward the tip side.

実施形態の注出用スパウト１０によれば、空気流路３５が注出筒部２３の内側で延び、空気出口３５ｂが管状部３４の側方に開口しているので、閉止位置では内容物流路２４と共に空気出口３５ｂが閉止される。また、可動部材３０を閉止位置から開放位置に移動させることで、内容物流路２４が外部に開口すると共に、空気出口３５ｂが本体容器１２内に開口する。内容物流路２４と空気流路３５は、管状部３４及び被覆部２７により区画されるので、液体等の内容物Ｌが注出しやすくなる。 According to the pouring spout 10 of the embodiment, since the air flow path 35 extends inside the pouring cylinder portion 23 and the air outlet 35b opens to the side of the tubular portion 34, the content flow path is in the closed position. The air outlet 35b is closed together with the 24. Further, by moving the movable member 30 from the closed position to the open position, the content flow path 24 opens to the outside and the air outlet 35b opens into the main body container 12. Since the content flow path 24 and the air flow path 35 are partitioned by the tubular portion 34 and the covering portion 27, the content L such as a liquid can be easily poured out.

以上、本発明を好適な実施形態に基づいて説明してきたが、本発明は上述の実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の改変が可能である。 Although the present invention has been described above based on the preferred embodiment, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

実施形態の注出用スパウト１０は、スライド凹部２２、挿入溝２２ｂ、案内溝２５、被覆部２７等が、軸線方向に沿った可動部材３０のスライド移動に対応した案内部となっている。可動部材の移動方向は、軸線方向に沿った直線状のスライド移動に限定されず、ねじ等を用いた螺旋状のねじり運動、ヒンジ等を用いた円弧状の回転運動などでもよい。可動部材の移動方向に応じた向きを有する案内部をスパウト本体に設けることにより、所望の移動方向に対応することも可能である。 In the dispensing spout 10 of the embodiment, the slide recess 22, the insertion groove 22b, the guide groove 25, the covering portion 27, and the like are guide portions corresponding to the slide movement of the movable member 30 along the axial direction. The moving direction of the movable member is not limited to the linear sliding movement along the axial direction, and may be a spiral twisting motion using a screw or the like, an arcuate rotational motion using a hinge or the like, or the like. It is also possible to correspond to a desired moving direction by providing the spout body with a guide portion having a direction corresponding to the moving direction of the movable member.
