Must be larger than the maximum outer diameter of the outer sleeve main cylinder portion 33.

図８〜図１０に示すように、充填対象容器として採用する包装容器１２０の口首部１２１内径は注出用スパウト１０の外側スリーブ３０のスリーブ基部の左右方向寸法よりも小さい必要がある。
包装容器口首部１２１内径と外側スリーブ主筒部３３最大外径との差を、以下、挿入径ギャップ、とも言う。
外側スリーブ３０の左右両側のストッパ突片３２の左右方向の延在寸法が互いに異なる場合は、包装容器１２０は、挿入径ギャップを外側スリーブ３０の各ストッパ突片３２の左右方向の延在寸法に比べて小さいサイズで確保可能な口首部１２１内径を有するものを採用する。 As shown in FIGS. 8 to 10, the inner diameter of the mouth portion 121 of the packaging container 120 used as the container to be filled needs to be smaller than the left-right dimension of the sleeve base of the outer sleeve 30 of the pouring spout 10.
The difference between the inner diameter of the mouth portion 121 of the packaging container and the maximum outer diameter of the outer sleeve main cylinder portion 33 is hereinafter also referred to as an insertion diameter gap.
If the laterally extending dimensions of the stopper projecting pieces 32 on both the left and right sides of the outer sleeve 30 are different from each other, the packaging container 120 sets the insertion diameter gap to the laterally extending dimension of each stopper projecting piece 32 of the outer sleeve 30. The one having the inner diameter of the mouth portion 121 that can be secured in a smaller size is adopted.

図８〜図１０等に示すように、詰め替え容器１１０の内容物を包装容器１２０に充填するときには、詰め替え容器１１０の注出用スパウト１０の外側スリーブ主筒部３３をその内側の注出筒部２２とともに上向き状態にした包装容器１２０の口首部１２１にその上方から挿入する。
挿入径ギャップが外側スリーブ３０の各ストッパ突片３２の左右方向の延在寸法に比べて小さければ、包装容器口首部１２１にスリーブ本体３１を挿入した外側スリーブ３０の左右両側のストッパ突片３２を包装容器口首部１２１先端に当接させることができ、ストッパ突片３２の包装容器口首部１２１への落ち込みを確実に防ぐことができる。 As shown in FIGS. 8 to 10, when the contents of the refill container 110 are filled in the packaging container 120, the outer sleeve main cylinder portion 33 of the pouring spout 10 of the refill container 110 is inserted into the inner pouring cylinder portion. It is inserted into the mouth portion 121 of the packaging container 120, which is turned upward together with 22 from above.
If the insertion diameter gap is smaller than the lateral extension dimension of each stopper projecting piece 32 of the outer sleeve 30, the stopper projecting pieces 32 on both the left and right sides of the outer sleeve 30 in which the sleeve body 31 is inserted into the packaging container mouthpiece 121 are inserted. It can be brought into contact with the tip of the packaging container mouthpiece 121, and the stopper projecting piece 32 can be reliably prevented from falling into the packaging container mouthpiece 121.

注出用スパウト１０の外側スリーブ３０のストッパ突片３２は、包装容器口首部１２１先端に当接されることで外側スリーブ３０の包装容器口首部１２１に対する挿入方向の変位を規制する役割を果たす。
なお、外側スリーブ本体３１の包装容器口首部１２１に対する挿入方向の変位は、外側スリーブ本体３１の包装容器１２０に対する挿入長の増大を意味する。 The stopper projecting piece 32 of the outer sleeve 30 of the pouring spout 10 plays a role of restricting the displacement of the outer sleeve 30 with respect to the packaging container mouth portion 121 by being brought into contact with the tip of the packaging container mouth portion 121.
The displacement of the outer sleeve main body 31 with respect to the packaging container mouth portion 121 in the insertion direction means an increase in the insertion length of the outer sleeve main body 31 with respect to the packaging container 120.

注出用スパウト１０は、外側スリーブ３０の左右両側のストッパ突片３２の左右方向延在寸法がそれぞれ挿入径ギャップに比べて大きい構成により、外側スリーブ主筒部３３を挿入した包装容器口首部１２１の先端にストッパ突片３２を当接させるだけで、包装容器口首部１２１に対する挿入方向の位置決めを容易に実現できる。
各ストッパ突片３２の左右方向延在寸法は、挿入径ギャップに比べて１ｍｍ以上大きいことが好ましく、２ｍｍ以上大きいことが依り好ましい。 The pouring spout 10 has a configuration in which the lateral extension dimensions of the stopper protrusions 32 on both the left and right sides of the outer sleeve 30 are larger than the insertion diameter gap, so that the packaging container mouth portion 121 into which the outer sleeve main cylinder portion 33 is inserted is inserted. By simply bringing the stopper projecting piece 32 into contact with the tip of the package container, positioning in the insertion direction with respect to the mouthpiece 121 of the packaging container can be easily realized.
The lateral extension dimension of each stopper projecting piece 32 is preferably 1 mm or more larger than the insertion diameter gap, and more preferably 2 mm or more.

図８〜図１０等に示すように、ストッパ突片３２の両面のうち外側スリーブ主筒部３３が延出されている側の面は、外側スリーブ３０のスリーブ本体３１を挿入した包装容器１２０の口首部１２１先端が当接される口首部突き当て面３２ａである。
口首部突き当て面３２ａはその全体がスリーブ本体３１軸線に垂直に延在形成されている。 As shown in FIGS. 8 to 10 and the like, the side of both sides of the stopper projecting piece 32 on which the outer sleeve main cylinder portion 33 extends is the packaging container 120 into which the sleeve body 31 of the outer sleeve 30 is inserted. It is a mouthpiece abutting surface 32a to which the tip of the mouthpiece 121 comes into contact.
The entire mouth abutting surface 32a is formed so as to extend perpendicular to the sleeve body 31 axis.

外側スリーブ３０のスリーブ本体３１を挿入した包装容器口首部１２１先端は、外側スリーブ３０の各ストッパ突片３２（具体的には口首部突き当て面３２ａ）にその前後方向一側から他側にわたって横切るように面接触または線接触して当接される。
外側スリーブ３０の左右両側のストッパ突片３２の口首部突き当て面３２ａは、包装容器口首部１２１先端に当接させることで、外側スリーブ３０を外側スリーブ本体３１軸線が包装容器口首部１２１軸線に平行な向きで包装容器口首部１２１に支持させる役割を果たす。 The tip of the mouthpiece 121 of the packaging container into which the sleeve body 31 of the outer sleeve 30 is inserted crosses each stopper projecting piece 32 (specifically, the mouthpiece abutting surface 32a) of the outer sleeve 30 from one side in the front-rear direction to the other side. They are brought into contact with each other by surface contact or line contact.
The abutting surface 32a of the stopper protrusions 32 on both the left and right sides of the outer sleeve 30 is brought into contact with the tip of the packaging container mouth 121 so that the outer sleeve 30 is brought into contact with the outer sleeve body 31 axis to the packaging container mouth 121 axis. It serves to support the packaging container mouth portion 121 in a parallel orientation.

通気路１２は、包装容器口首部１２１内径と外側スリーブ本体３１最大外径との差である挿入径ギャップの存在によって確保される。
包装容器１２０は、口首部１２１内径が外側スリーブ本体３１最大外径に比べて０．５ｍｍ以上大きいものが好ましく、１ｍｍ以上大きいものが依り好ましい。 As shown in FIGS. 8 to 10, in the packaging container 120, the contents are filled from the refill container 110 to the packaging container 120 between the outer sleeve main body 31 inserted into the mouth portion 121 and the inner peripheral surface of the mouth portion 121. A container capable of securing a gap (ventilation passage 12 in FIGS. 8 to 10) for air exhaust from the packaging container 120 as it progresses is adopted.
The ventilation path 12 is secured by the presence of an insertion diameter gap, which is the difference between the inner diameter of the packaging container mouth 121 and the maximum outer diameter of the outer sleeve body 31.
The packaging container 120 preferably has an inner diameter of the mouth portion 121 larger than the maximum outer diameter of the outer sleeve body 31 by 0.5 mm or more, and more preferably 1 mm or more.

図５に示すように、突部同士当接閉止状態の注出用スパウト１０においては、スパウト本体２０の受け側突部２７の位置決め凹部２７ｃに位置決め突起３７ｃが挿入（収容）されていることで、スパウト本体２０に対する外側スリーブ３０の軸回り回転が規制される。 As shown in FIG. 5, in the pouring spout 10 in the state where the protrusions are in contact with each other and closed, the positioning protrusion 37c is inserted (accommodated) into the positioning recess 27c of the receiving side protrusion 27 of the spout body 20. , The axial rotation of the outer sleeve 30 with respect to the spout body 20 is restricted.

図３、図９、図１０等に示すように、スパウト本体２０は、封止嵌合部２４の側面から突出された係止突起２４ｂを含む。
図３、図９、図１０等に示すスパウト本体２０の係止突起２４ｂは、封止嵌合部２４の側面全周にわたって延在するリブ状に形成されている。図１０に示すように、外側スリーブ３０の嵌合受け部３４の内周面には、スパウト本体２０の係止突起２４ｂを挿入、嵌合させる溝状の係止凹部３４ａが全周にわたって延在形成されている。 As shown in FIGS. 3, 9, 10, 10 and the like, the spout body 20 includes a locking projection 24b protruding from the side surface of the sealing fitting portion 24.
The locking projection 24b of the spout body 20 shown in FIGS. 3, 9, 10, 10 and the like is formed in a rib shape extending over the entire side surface of the sealing fitting portion 24. As shown in FIG. 10, a groove-shaped locking recess 34a for inserting and fitting the locking projection 24b of the spout body 20 extends over the entire circumference on the inner peripheral surface of the fitting receiving portion 34 of the outer sleeve 30. It is formed.

図３に示すように、係止突起２４ｂは、封止嵌合部２４を外側スリーブ３０の嵌合受け部３４内側に嵌合させたときに、嵌合受け部３４内周面に形成されている係止凹部３４ａに入り込ませることができる。係止突起２４ｂは、嵌合受け部３４内周面に形成されている係止凹部３４ａに入り込ませることで、外側スリーブ３０をスパウト本体２０に対して嵌合位置に位置決めする。
突部同士当接閉止状態の注出用スパウト１０において、係止突起２４ｂは、嵌合受け部３４内周面に形成されている係止凹部３４ａに入り込む。 As shown in FIG. 3, the locking projection 24b is formed on the inner peripheral surface of the fitting receiving portion 34 when the sealing fitting portion 24 is fitted inside the fitting receiving portion 34 of the outer sleeve 30. It can be inserted into the locking recess 34a. The locking projection 24b is inserted into the locking recess 34a formed on the inner peripheral surface of the fitting receiving portion 34 to position the outer sleeve 30 at the fitting position with respect to the spout body 20.
In the pouring spout 10 in the state where the protrusions are in contact with each other and closed, the locking projection 24b enters the locking recess 34a formed on the inner peripheral surface of the fitting receiving portion 34.

但し、係止突起２４ｂは、外側スリーブ３０を手指でスパウト本体２０に対してスパウト本体２０基端側へ相対移動させる操作によって、嵌合受け部３４の係止凹部３４ａに対して強制的に挿脱させることができる。嵌合受け部３４内周面の係止凹部３４ａに入り込ませた係止突起２４ｂは、外側スリーブ３０の封止嵌合部２４に対する注出筒部２２軸線方向の移動抵抗を増大させる。嵌合受け部３４内周面の係止凹部３４ａに入り込ませた係止突起２４ｂは、外側スリーブ３０の嵌合受け部３４の封止嵌合部２４からスパウト本体２０先端側への不用意な抜け出しを防ぐ役割を果たす。 However, the locking projection 24b is forcibly inserted into the locking recess 34a of the fitting receiving portion 34 by the operation of moving the outer sleeve 30 relative to the spout main body 20 toward the base end side of the spout main body 20 by fingers. You can take it off. The locking projection 24b inserted into the locking recess 34a on the inner peripheral surface of the fitting receiving portion 34 increases the movement resistance of the outer sleeve 30 with respect to the sealing fitting portion 24 in the ejection cylinder portion 22 in the axial direction. The locking projection 24b inserted into the locking recess 34a on the inner peripheral surface of the fitting receiving portion 34 is careless from the sealing fitting portion 24 of the fitting receiving portion 34 of the outer sleeve 30 to the tip side of the spout body 20. It plays a role in preventing escape.

係止突起２４ｂは、封止嵌合部２４側面からの突出寸法が最大の頂部からスパウト本体２０先端側の部分がスパウト本体２０先端側へ行くにしたがって封止嵌合部２４側面からの突出寸法が減少するテーパ状に形成されている構成を好適に採用できる。
係止突起２４ｂは、例えば、封止嵌合部２４側面周方向に垂直の断面が半円状、三角形状等のものを採用できる。 The locking projection 24b has a protrusion from the side surface of the sealing fitting portion 24 as the portion on the tip side of the spout body 20 goes from the top having the maximum protrusion dimension from the side surface of the sealing fitting portion 24 toward the tip side of the spout body 20. A structure formed in a tapered shape in which the amount of water is reduced can be preferably adopted.
As the locking projection 24b, for example, one having a semicircular or triangular cross section perpendicular to the side surface circumferential direction of the sealing fitting portion 24 can be adopted.

係止突起２４ｂは、封止嵌合部２４の側面全周にわたって延在するリブ状に限定されず、封止嵌合部２４の側面の周方向の一部に形成された突起であっても良い。
外側スリーブ３０の嵌合受け部３４内周面の係止凹部３４ａは、スパウト本体２０の係止突起２４ｂを挿入、嵌合可能な形状に形成される。 The locking protrusion 24b is not limited to a rib shape extending over the entire side surface of the sealing fitting portion 24, and may be a protrusion formed on a part of the side surface of the sealing fitting portion 24 in the circumferential direction. good.
The locking recess 34a on the inner peripheral surface of the fitting receiving portion 34 of the outer sleeve 30 is formed into a shape that allows the locking projection 24b of the spout body 20 to be inserted and fitted.

図３、図４、図１０に示すように、スパウト本体２０の注出筒部２２の側面の軸線方向複数箇所には、その周方向全周に延在する液止めリブ２８が突設されている。
注出筒部２２は液止めリブ２８を含む。
液止めリブ２８は、注出筒部２２の円筒状の側面主部から突出され、注出筒部２２の側面の一部を形成する。 As shown in FIGS. 3, 4, and 10, liquid stop ribs 28 extending all around the circumferential direction are projected at a plurality of axial directions on the side surface of the dispensing cylinder portion 22 of the spout main body 20. There is.
The dispensing cylinder portion 22 includes a liquid stop rib 28.
The liquid stop rib 28 protrudes from the cylindrical side surface main portion of the pouring cylinder portion 22 and forms a part of the side surface of the pouring cylinder portion 22.

図３、図１０に示すように、外側スリーブ本体３１の内周面、すなわち、外側スリーブ本体３１内側の貫通孔（スリーブ貫通孔）内周面は、液止めリブ２８に当接されている。 液止めリブ２８は外側スリーブ３０と注出筒部２２との間の内容物の通過を阻止する役割を果たす。このため、詰め替え容器１１０の注出用スパウト１０が突部同士当接閉止状態にあるとき、詰め替え容器１１０の内容物が外側スリーブ３０によって覆われた注出口２５ｂから注出筒部２２と外側スリーブ３０との間を通過して外側スリーブ３０基端から漏出することを防止できる。 As shown in FIGS. 3 and 10, the inner peripheral surface of the outer sleeve main body 31, that is, the inner peripheral surface of the through hole (sleeve through hole) inside the outer sleeve main body 31 is in contact with the liquid stop rib 28. The liquid stop rib 28 serves to prevent the passage of the contents between the outer sleeve 30 and the pouring cylinder portion 22. Therefore, when the pouring spout 10 of the refill container 110 is in the contacted and closed state between the protrusions, the contents of the refill container 110 are covered with the outer sleeve 30 from the pouring outlet 25b, and the pouring cylinder portion 22 and the outer sleeve are used. It is possible to prevent leakage from the base end of the outer sleeve 30 by passing between the outer sleeve 30 and the base 30.

液止めリブ２８は外側スリーブ３０と注出筒部２２との接触面積を小さく抑えて外側スリーブ３０の注出筒部２２に対する摺動抵抗を小さくする役割を果たす。
外側スリーブ３０は、注出筒部２２側面に突出形成された液止めリブ２８の突端に摺動しつつ、スパウト本体２０の注出用突部２６に対して注出筒部２２軸線方向にスライド移動可能且つ軸回り回転可能に外挿されている。
液止めリブ２８は、外側スリーブ３０の注出筒部２２に対する注出筒部２２軸線方向にスライド移動可能及び軸回り回転の円滑化に有効に寄与する。 The liquid stop rib 28 plays a role of suppressing the contact area between the outer sleeve 30 and the pouring cylinder portion 22 to be small and reducing the sliding resistance of the outer sleeve 30 to the pouring cylinder portion 22.
The outer sleeve 30 slides in the direction of the pouring cylinder 22 axis with respect to the pouring protrusion 26 of the spout body 20 while sliding on the tip of the liquid stop rib 28 protruding from the side surface of the pouring cylinder 22. It is extrapolated so that it can be moved and rotated around the axis.
The liquid stop rib 28 can slide and move in the axial direction of the pouring cylinder portion 22 with respect to the pouring cylinder portion 22 of the outer sleeve 30, and effectively contributes to smooth rotation around the axis.

なお、注出用スパウト１０は、液止めリブ２８が存在せず、外側スリーブ３０を、スパウト本体２０の注出用突部２６に対して、注出筒部２２の円筒状の側面（側面主部）に摺動させつつ、注出筒部２２軸線方向へのスライド移動及び軸回り回転させることができる構成も採用可能である。 The pouring spout 10 does not have a liquid stop rib 28, and the outer sleeve 30 has a cylindrical side surface (side surface main) of the pouring cylinder 22 with respect to the pouring protrusion 26 of the spout body 20. It is also possible to adopt a configuration in which the pouring cylinder portion can be slid in the 22-axis direction and rotated around the axis while sliding on the portion).

図３等に示すように、スパウト本体２０の封止嵌合部２４の流路仕切り壁２３とは逆側の面である先端面は、全体が注出筒部２２軸線方向に垂直の平坦面とされている。
スパウト本体２０は、封止嵌合部２４の先端面に凹凸が存在する構成も採用可能である。但し、封止嵌合部２４の先端面全体が注出筒部２２軸線方向に垂直の平坦面である構成は、凹部が存在する場合に凹部に埃が溜まり汚れの原因となるといった不都合を防止できる点で有利である。 As shown in FIG. 3 and the like, the tip surface of the sealing fitting portion 24 of the spout body 20 opposite to the flow path partition wall 23 is a flat surface that is entirely perpendicular to the pouring cylinder portion 22 in the axial direction. It is said that.
The spout body 20 can also adopt a configuration in which the tip surface of the sealing fitting portion 24 has irregularities. However, the configuration in which the entire tip surface of the sealing fitting portion 24 is a flat surface perpendicular to the pouring cylinder portion 22 in the axial direction prevents inconveniences such as dust accumulating in the recesses and causing stains when there are recesses. It is advantageous in that it can be done.

図３等に示すように、突部同士当接閉止状態の注出用スパウト１０において、スパウト本体２０の封止嵌合部２４の先端面は、嵌合受け部３４を含む外側スリーブ３０の先端面と面一となり、外側スリーブ３０の先端面との間に埃が溜まる隙間が形成されない。 As shown in FIG. 3 and the like, in the pouring spout 10 in the state where the protrusions are in contact with each other and closed, the tip surface of the sealing fitting portion 24 of the spout body 20 is the tip of the outer sleeve 30 including the fitting receiving portion 34. It is flush with the surface, and a gap for collecting dust is not formed between the outer sleeve 30 and the tip surface.

ここで、注出用スパウト１０が突部同士当接閉止状態の詰め替え容器１１０の内容物を包装容器１２０に注出する手順の一例を説明する。
この手順は、まず、外側スリーブ３０を手指で操作して図７、図８に示すように外側スリーブ３０をスパウト本体２０に対するスパウト本体２０軸回り方向の向きを突き当て回避向きとする押し込み規制解除操作を行う。図７、図８に例示する注出用スパウト１０の押し込み規制解除操作は、外側スリーブ３０の左右方向をスパウト本体２０の前後方向に合わせる操作である。 Here, an example of a procedure for pouring out the contents of the refill container 110 in which the spouts 10 for pouring are in contact with each other and closed to each other to the packaging container 120 will be described.
In this procedure, first, the outer sleeve 30 is operated by fingers, and as shown in FIGS. 7 and 8, the outer sleeve 30 is abutted against the spout body 20 in the direction around the spout body 20 axis to avoid pushing regulation. Perform the operation. The push-in restriction release operation of the pouring spout 10 illustrated in FIGS. 7 and 8 is an operation of aligning the left-right direction of the outer sleeve 30 with the front-rear direction of the spout body 20.

押し込み規制解除操作が完了したら、次に、図８に示すように注出用スパウト１０の外側スリーブ主筒部３３を上向き状態の包装容器１２０の口首部１２１にその上方から挿入して外側スリーブ３０のストッパ突片３２を包装容器口首部１２１先端に当接させるスパウト挿入操作を行なう。 After the push-in restriction release operation is completed, next, as shown in FIG. 8, the outer sleeve main cylinder portion 33 of the dispensing spout 10 is inserted into the mouth portion 121 of the packaging container 120 in the upward state from above, and the outer sleeve 30 is inserted. The spout insertion operation is performed so that the stopper projecting piece 32 of the above is brought into contact with the tip of the mouthpiece 121 of the packaging container.

次いで、詰め替え容器１１０の容器部１１１を下方へ押圧して注出用スパウト１０のスパウト本体２０を容器部１１１を介して外側スリーブ３０に対してその先端側へ向かってスライド移動させ、図９〜図１１に示すようにスパウト本体２０の封止嵌合部２４を外側スリーブ３０の先端開口部３８から下方へ離脱させて注出口２５ｂを開放する押し込み開放操作を行なう。
スパウト本体２０の注出口２５ｂが開放されれば、詰め替え容器１１０の内容物を注出口２５ｂから包装容器１２０に注出できる。 Next, the container portion 111 of the refill container 110 is pressed downward to slide the spout body 20 of the pouring spout 10 toward the tip end side with respect to the outer sleeve 30 via the container portion 111, and FIGS. As shown in FIG. 11, a push-open operation is performed in which the sealing fitting portion 24 of the spout body 20 is detached downward from the tip opening 38 of the outer sleeve 30 to open the spout 25b.
When the spout main body 20's spout 25b is opened, the contents of the refill container 110 can be poured from the spout 25b into the packaging container 120.

注出用スパウト１０について、注出口２５ｂが開放された状態を、以下、注出口開放状態、とも言う。
注出用スパウト１０は、突部同士当接閉止状態から押し込み規制解除操作を行なうだけで押し込み開放操作にて注出口開放状態とすることが可能な状態となる。
注出用スパウト１０は、突部同士当接閉止状態から押し込み規制解除操作、スパウト挿入操作、押し込み開放操作を行なうだけで、注出口開放状態とすることができる。注出用スパウト１０は突部同士当接閉止状態から簡単な操作により注出口開放状態とすることができる。 Regarding the spout for pouring 10, the state in which the spout 25b is open is also referred to as an open spout state.
The pouring spout 10 is in a state in which the spout can be opened by the pushing-opening operation only by performing the pushing-in restriction release operation from the state in which the protrusions are in contact with each other and closed.
The pouring spout 10 can be brought into the spout opening state only by performing the push-in restriction release operation, the spout insertion operation, and the push-open operation from the state in which the protrusions are in contact with each other and closed. The pouring spout 10 can be brought into the spout open state by a simple operation from the state in which the protrusions are in contact with each other and closed.

以下、注出用スパウト１０が突部同士当接閉止状態の詰め替え容器１１０の内容物を包装容器１２０に注出する手順について、より具体的に説明する。
押し込み規制解除操作では、まず、外側スリーブ３０をスパウト本体２０に対してスパウト本体２０先端側へ若干スライド移動させて、スパウト本体２０の受け側突部２７の位置決め凹部２７ｃに挿入状態の位置決め突起３７ｃを位置決め凹部２７ｃから抜き出す。次いで、位置決め突起３７ｃを位置決め凹部２７ｃから抜き出した状態を維持したまま、外側スリーブ３０をスパウト本体２０に対して軸回り回転させて、図７、図８に示すように外側スリーブ３０の左右方向をスパウト本体２０の前後方向に合わせる。 Hereinafter, a procedure for pouring out the contents of the refill container 110 in which the spouts 10 for pouring are in contact with each other and closed to each other to the packaging container 120 will be described in more detail.
In the push-in restriction release operation, first, the outer sleeve 30 is slightly slid toward the tip side of the spout body 20 with respect to the spout body 20, and the positioning protrusion 37c inserted into the positioning recess 27c of the receiving side protrusion 27 of the spout body 20. Is extracted from the positioning recess 27c. Next, while maintaining the state in which the positioning protrusion 37c is pulled out from the positioning recess 27c, the outer sleeve 30 is rotated about the axis with respect to the spout body 20 to rotate the outer sleeve 30 in the left-right direction as shown in FIGS. 7 and 8. Align with the front-back direction of the spout body 20.

図３に示すように、位置決め突起３７ｃの受け側突部２７突端面から外側スリーブ３０基端側への突出寸法（以下、単に、突出寸法、とも言う）は０．５〜２ｍｍ程度であることが好適である。
押し込み規制解除操作において、外側スリーブ３０は、スパウト本体２０に対してスパウト本体２０先端側へ、位置決め突起３７ｃの突出寸法に相当する距離あるいはこの距離を若干上回る距離だけスライド移動させた後、スパウト本体２０に対して軸回り回転させて、スパウト本体２０に対するスパウト本体２０軸回り方向の向きを突き当て回避向きとする。 As shown in FIG. 3, the protruding dimension (hereinafter, simply referred to as the protruding dimension) of the positioning protrusion 37c from the projecting end surface of the receiving side projecting portion 27 to the base end side of the outer sleeve 30 is about 0.5 to 2 mm. Is preferable.
In the push-in restriction release operation, the outer sleeve 30 is slid to the tip end side of the spout body 20 with respect to the spout body 20 by a distance corresponding to the protruding dimension of the positioning protrusion 37c or a distance slightly exceeding this distance, and then the spout body. It is rotated about the axis with respect to 20, and the direction in the direction around the axis of the spout body 20 with respect to the spout body 20 is set as the avoidance direction.

図３に示すように、突部同士当接閉止状態の注出用スパウト１０において、スパウト本体２０の封止嵌合部２４側面はその全体が外側スリーブ３０の嵌合受け部３４内周面に当接される。
スパウト本体２０の封止嵌合部２４側面の注出筒部２２軸線方向の寸法は、位置決め突起３７ｃの突出寸法に比べて格段に大きく確保されている。
このため、注出用スパウト１０は、外側スリーブ３０の先端開口部３８がその内側に嵌合された封止嵌合部２４によって閉止された状態を維持しつつ押し込み規制解除操作を行なうことが容易である。 As shown in FIG. 3, in the pouring spout 10 in the state where the protrusions are in contact with each other and closed, the entire side surface of the sealing fitting portion 24 of the spout body 20 is on the inner peripheral surface of the fitting receiving portion 34 of the outer sleeve 30. Be abutted.
The dimension of the spout main body 20 on the side surface of the sealing fitting portion 24 in the direction of the ejection cylinder 22 axis is remarkably large as compared with the protruding dimension of the positioning protrusion 37c.
Therefore, it is easy for the pouring spout 10 to perform the push-in restriction release operation while maintaining the state in which the tip opening 38 of the outer sleeve 30 is closed by the sealing fitting portion 24 fitted inside the outer sleeve 30. Is.

スパウト本体２０の封止嵌合部２４側面の注出筒部２２軸線方向の寸法は、位置決め突起３７ｃの突出寸法に比べて２ｍｍ以上大きいことが好ましく、位置決め突起３７ｃの突出寸法に比べて３ｍｍ以上大きいことが依り好ましい。
スパウト本体２０の封止嵌合部２４側面の注出筒部２２軸線方向の寸法は、注出用スパウト１０の実用的サイズに鑑みて３０ｍｍ以下であることが好ましい。 The dimension of the spout body 20 on the side surface of the sealing fitting portion 24 in the 22-axis direction is preferably 2 mm or more larger than the protruding dimension of the positioning protrusion 37c, and 3 mm or more compared to the protruding dimension of the positioning protrusion 37c. Larger is more preferable.
The dimension of the ejection cylinder portion 22 in the axial direction on the side surface of the sealing fitting portion 24 of the spout main body 20 is preferably 30 mm or less in view of the practical size of the ejection spout 10.

図８に示すように、スパウト挿入操作では、外側スリーブ３０のストッパ突片３２の口首部突き当て面３２ａを包装容器口首部１２１先端に当接させる。
外側スリーブ３０のストッパ突片３２が包装容器口首部１２１先端に当接されたとき、外側スリーブ本体３１の主筒部３３はその全体が包装容器１２０内に収容される。 As shown in FIG. 8, in the spout insertion operation, the mouthpiece abutting surface 32a of the stopper projecting piece 32 of the outer sleeve 30 is brought into contact with the tip of the packaging container mouthpiece 121.
When the stopper projecting piece 32 of the outer sleeve 30 comes into contact with the tip of the mouthpiece 121 of the packaging container, the entire main cylinder 33 of the outer sleeve body 31 is housed in the packaging container 120.

図９〜図１１に示すように、押し込み開放操作では、スパウト本体２０を外側スリーブ３０に対してその先端側へスライド移動させ、スパウト本体２０の一対の受け側突部２７間に外側スリーブ３０のスリーブ基部を挿入し、且つ、スパウト本体２０のスリーブ受け部２１ｃを外側スリーブ３０の一対の押し込み規制突部３７間（具体的には、押し込み規制突部本体３７ｄ）に挿入する。また、スパウト本体２０の封止嵌合部２４を外側スリーブ３０の先端開口部３８から下方へ離脱させて注出口２５ｂを開放し、注出用スパウト１０を注出口開放状態とする。 As shown in FIGS. 9 to 11, in the push-open operation, the spout body 20 is slid toward the tip end side of the outer sleeve 30, and the outer sleeve 30 is placed between the pair of receiving side protrusions 27 of the spout body 20. The sleeve base is inserted, and the sleeve receiving portion 21c of the spout body 20 is inserted between the pair of push-restriction protrusions 37 of the outer sleeve 30 (specifically, the push-restriction protrusion body 37d). Further, the sealing fitting portion 24 of the spout body 20 is separated downward from the tip opening 38 of the outer sleeve 30 to open the spout 25b, and the spout 10 for pouring is put into the spout open state.

図９〜図１１に示すように、押し込み開放操作において、スパウト本体２０は、その取付部２１のスリーブ受け部２１c（具体的にはそのスリーブ受け面２１ｄ）が外側スリーブ３０のスリーブ基部に当接するまで、外側スリーブ３０に対してその先端側へ向かってスライド移動（押し込み）可能である。 As shown in FIGS. 9 to 11, in the push-open operation, the sleeve receiving portion 21c (specifically, the sleeve receiving surface 21d) of the mounting portion 21 of the spout main body 20 comes into contact with the sleeve base of the outer sleeve 30. Up to, the outer sleeve 30 can be slid and moved (pushed) toward the tip side thereof.

スパウト本体２０は、取付部２１のスリーブ受け部２１ｃが外側スリーブ３０のスリーブ基部に当接することで、外側スリーブ３０先端側へのそれ以上の移動（押し込み）が規制される。
注出用スパウト１０について、スパウト本体２０の取付部２１のスリーブ受け部２１ｃが外側スリーブ３０のスリーブ基部に当接された状態を、以下、押し込み限界状態、とも言う。
図９〜図１１は、押し込み限界状態の注出用スパウト１０を示す。 In the spout body 20, the sleeve receiving portion 21c of the mounting portion 21 comes into contact with the sleeve base of the outer sleeve 30, so that further movement (pushing) toward the tip end side of the outer sleeve 30 is restricted.
Regarding the pouring spout 10, the state in which the sleeve receiving portion 21c of the mounting portion 21 of the spout body 20 is in contact with the sleeve base of the outer sleeve 30 is hereinafter also referred to as a push-in limit state.
9 to 11 show the pouring spout 10 in the push-in limit state.

図３に示すように、突部同士当接閉止状態の注出用スパウト１０の外側スリーブ３０のスリーブ基部とスパウト本体２０の取付部２１のスリーブ受け部２１c（具体的にはそのスリーブ受け面２１ｄ）との間の離間距離は、注出用スパウト１０の先端部摺接寸法に比べて格段に大きい。
このため、図９〜図１１に示すように、押し込み開放操作では、スパウト本体２０の取付部２１のスリーブ受け部２１ｃ（具体的にはそのスリーブ受け面２１ｄ）が外側スリーブ３０のスリーブ基部に当接するまでに注出口２５ｂを開放できる。
注出用スパウト１０が押し込み限界状態となったとき、注出口２５ｂの開口量は最大となる。 As shown in FIG. 3, the sleeve base of the outer sleeve 30 of the pouring spout 10 in a closed state where the protrusions are in contact with each other and the sleeve receiving portion 21c of the mounting portion 21 of the spout body 20 (specifically, the sleeve receiving surface 21d). ) Is much larger than the sliding contact dimension of the tip of the pouring spout 10.
Therefore, as shown in FIGS. 9 to 11, in the push-open operation, the sleeve receiving portion 21c (specifically, the sleeve receiving surface 21d) of the mounting portion 21 of the spout body 20 hits the sleeve base of the outer sleeve 30. The spout 25b can be opened by the time it comes into contact.
When the pouring spout 10 reaches the push-in limit state, the opening amount of the pouring outlet 25b becomes maximum.

図９〜図１１等に示すスパウト本体２０の受け側突部２７の取付部２１からスパウト本体２０先端側への突出寸法（本明細書において、単に、突出寸法、とも言う）は、外側スリーブ３０のストッパ突片３２の厚み寸法に比べて小さい。
図９〜図１１に示す押し込み限界状態の注出用スパウト１０のスパウト本体２０の受け側突部２７は包装容器口首部１２１先端に当接せず、外側スリーブ３０のストッパ突片３２の包装容器口首部１２１先端への障害にならない。 The protrusion dimension (also simply referred to as the protrusion dimension in the present specification) from the mounting portion 21 of the receiving side protrusion 27 of the spout body 20 to the tip end side of the spout body 20 shown in FIGS. 9 to 11 is the outer sleeve 30. It is smaller than the thickness dimension of the stopper projecting piece 32 of.
The receiving side protrusion 27 of the spout body 20 of the ejection limit state shown in FIGS. 9 to 11 does not abut on the tip of the mouthpiece 121 of the packaging container, and the packaging container of the stopper protrusion 32 of the outer sleeve 30. It does not interfere with the tip of the mouth 121.

注出用スパウト１０は、スパウト本体２０の受け側突部２７の取付部２１からの突出寸法が、外側スリーブ３０のストッパ突片３２の厚み寸法と同等以上である構成も採用可能である。
受け側突部２７の取付部２１からの突出寸法が外側スリーブ３０のストッパ突片３２の厚み寸法に比べて小さい構成は、受け側突部２７が、外側スリーブ主筒部３３を包装容器口首部１２１に挿入した注出用スパウト１０の外側スリーブ３０のストッパ突片３２の包装容器口首部１２１先端に対する当接状態に影響を与えることを回避できる。 The pouring spout 10 can also adopt a configuration in which the protrusion dimension of the receiving side protrusion 27 of the spout body 20 from the mounting portion 21 is equal to or larger than the thickness dimension of the stopper protrusion 32 of the outer sleeve 30.
The protrusion of the receiving side protrusion 27 from the mounting portion 21 is smaller than the thickness dimension of the stopper protrusion 32 of the outer sleeve 30. It is possible to avoid affecting the contact state of the stopper protrusion 32 of the outer sleeve 30 of the ejection spout 10 inserted into 121 with respect to the tip of the packaging container mouthpiece 121.

外側スリーブ主筒部３３を包装容器口首部１２１に挿入した注出用スパウト１０は、外側スリーブ３０のストッパ突片３２の口首部突き当て面３２ａを包装容器口首部１２１先端に当接させることで、注出筒部２２軸線が包装容器口首部１２１軸線に平行な向きを安定維持できる。
受け側突部２７の取付部２１からの突出寸法が外側スリーブ３０のストッパ突片３２の厚み寸法に比べて小さい構成は、注出筒部２２軸線が包装容器口首部１２１軸線に平行な向きを安定維持することに有利である。 The pouring spout 10 in which the outer sleeve main cylinder portion 33 is inserted into the packaging container mouth portion 121 is formed by bringing the mouth portion abutting surface 32a of the stopper projecting piece 32 of the outer sleeve 30 into contact with the tip of the packaging container mouth portion 121. , The direction in which the 22-axis line of the pouring tube portion is parallel to the 121-axis line of the mouthpiece of the packaging container can be stably maintained.
In the configuration in which the protrusion dimension of the receiving side protrusion 27 from the mounting portion 21 is smaller than the thickness dimension of the stopper protrusion 32 of the outer sleeve 30, the 22 axis of the dispensing tube portion is oriented parallel to the 121 axis of the packaging container mouth portion 121. It is advantageous to maintain stability.

外側スリーブ３０のスパウト本体２０に対する注出筒部２２軸回り方向の向きであって、外側スリーブ３０の押し込み規制突部３７がスパウト本体２０の受け側突部２７にスパウト本体２０先端側から当接可能な向きを、以下、突部同士当接向き、とも言う。
突部同士当接閉止状態の注出用スパウト１０の外側スリーブ３０はスパウト本体２０に対して突部同士当接向きとなっている。 The direction of the outer sleeve 30 with respect to the spout body 20 in the direction around the 22nd axis, and the push-restriction protrusion 37 of the outer sleeve 30 abuts on the receiving side protrusion 27 of the spout body 20 from the tip side of the spout body 20. The possible direction is also referred to as the direction in which the protrusions are in contact with each other.
The outer sleeve 30 of the pouring spout 10 in the closed state where the protrusions are in contact with each other is oriented so that the protrusions are in contact with each other with respect to the spout body 20.

なお、突部同士当接向きは、外側スリーブ３０の押し込み規制突部３７の位置決め突起３７ｃがスパウト本体２０の受け側突部２７の位置決め凹部２７ｃに収容される向きに限定されない。突部同士当接向きは、押し込み規制突部本体３７ｄの突端面の位置決め突起３７ｃを避けた位置が受け側突部２７にスパウト本体２０先端側から当接する向きも含む。 The direction of contact between the protrusions is not limited to the direction in which the positioning protrusion 37c of the push-restriction protrusion 37 of the outer sleeve 30 is accommodated in the positioning recess 27c of the receiving side protrusion 27 of the spout body 20. The direction of contact between the protrusions includes the direction in which the position of the push-restricted protrusion main body 37d avoiding the positioning protrusion 37c on the protrusion comes into contact with the receiving side protrusion 27 from the tip side of the spout body 20.

押し込み規制解除操作にて突部同士当接閉止状態の注出用スパウト１０の外側スリーブ３０をスパウト本体２０に対して軸回り回転させて突部同士当接向きからずらしても、外側スリーブ３０のスパウト本体２０軸回り方向の向きが突き当て回避向きからずれている場合は、押し込み開放操作のために外側スリーブ３０に対してその先端側に向かって押し込んだスパウト本体２０のスリーブ受け部２１ｃが外側スリーブ３０の押し込み規制突部３７先端に外側スリーブ３０基端側から当接される。この場合、注出用スパウト１０は押し込み限界状態に到達できない。 Even if the outer sleeve 30 of the pouring spout 10 in the closed state where the protrusions are in contact with each other is rotated about the axis with respect to the spout body 20 and the protrusions are displaced from the direction of contact with each other by the push-in restriction release operation, the outer sleeve 30 If the direction around the spout body 20 axis deviates from the abutting avoidance direction, the sleeve receiving portion 21c of the spout body 20 pushed toward the tip side of the outer sleeve 30 for the push-open operation is on the outside. The sleeve 30 is brought into contact with the tip of the push-restriction protrusion 37 from the base end side of the outer sleeve 30. In this case, the dispensing spout 10 cannot reach the push-in limit state.

なお、図９〜図１１等に示す注出用スパウト１０のスパウト本体２０の受け側突部２７の取付部２１からの突出寸法は、外側スリーブ３０の押し込み規制突部３７のストッパ突片３２から外側スリーブ３０基端側への突出寸法よりも小さい。
このため、押し込み開放操作にてスパウト本体２０のスリーブ受け部２１ｃが外側スリーブ３０の押し込み規制突部３７先端に外側スリーブ３０基端側から当接されたとき、スパウト本体２０の受け側突部２７は外側スリーブ３０のスリーブ基部に当接されない。 The protruding dimension of the spout body 20 of the spout 10 for dispensing shown in FIGS. 9 to 11 and the like from the mounting portion 21 of the receiving side protrusion 27 is from the stopper protrusion 32 of the push-restriction protrusion 37 of the outer sleeve 30. It is smaller than the protrusion dimension of the outer sleeve 30 toward the base end side.
Therefore, when the sleeve receiving portion 21c of the spout body 20 is brought into contact with the tip of the pushing restriction protrusion 37 of the outer sleeve 30 from the base end side of the outer sleeve 30 by the push-open operation, the receiving side protrusion 27 of the spout body 20 Is not abutted against the sleeve base of the outer sleeve 30.

押し込み開放操作のために外側スリーブ３０に対してその先端側に向かって押し込んだスパウト本体２０のスリーブ受け部２１ｃが外側スリーブ３０の押し込み規制突部３７先端に外側スリーブ３０基端側から当接されたとき、スパウト本体２０は注出用スパウト１０が突部同士当接閉止状態であるときに比べて外側スリーブ３０に対して外側スリーブ３０先端側へ、スパウト本体２０の受け側突部２７の取付部２１からの突出寸法に相当する距離だけスライド移動される。 The sleeve receiving portion 21c of the spout body 20 pushed toward the tip side of the outer sleeve 30 for the push-open operation is brought into contact with the tip of the push-restriction protrusion 37 of the outer sleeve 30 from the base end side of the outer sleeve 30. At that time, the spout body 20 attaches the receiving side protrusion 27 of the spout body 20 to the tip side of the outer sleeve 30 with respect to the outer sleeve 30 as compared with the case where the ejection spouts 10 are in contact with each other and closed. It is slid and moved by a distance corresponding to the protrusion dimension from the portion 21.

図３等に示すように、注出用スパウト１０のスパウト本体２０の受け側突部２７の取付部２１からの突出寸法は、スパウト本体２０の封止嵌合部２４側面の注出筒部２２軸線方向の寸法に比べて若干小さい。
このため、押し込み開放操作にてスパウト本体２０のスリーブ受け部２１ｃが外側スリーブ３０の押し込み規制突部３７先端に外側スリーブ３０基端側から当接されたとき、外側スリーブ本体３１の先端開口部３８がその内側に嵌合された封止嵌合部２４によって閉止された状態が維持され、注出口２５ｂは開放されない。 As shown in FIG. 3 and the like, the protruding dimension of the spout body 20 of the spout 10 for ejection from the mounting portion 21 of the receiving side protrusion 27 is the ejection cylinder portion 22 on the side surface of the sealing fitting portion 24 of the spout body 20. It is slightly smaller than the axial dimension.
Therefore, when the sleeve receiving portion 21c of the spout body 20 is brought into contact with the tip of the push-restriction protrusion 37 of the outer sleeve 30 from the base end side of the outer sleeve 30 by the push-open operation, the tip opening 38 of the outer sleeve body 31 Is maintained in a closed state by the sealing fitting portion 24 fitted inside, and the spout 25b is not opened.

注出用スパウト１０は、外側スリーブ３０がスパウト本体２０に対して注出筒部２２軸回り方向において限定された向きである突き当て回避向きにあるときのみ押し込み開放操作による注出口２５ｂの開放が可能である。
外側スリーブ３０がスパウト本体２０に対して突き当て回避向きにあるときのみ押し込み開放操作による注出口２５ｂの開放が可能な構成は、注出口２５ｂの不用意な開放の防止に有効に寄与する。 In the pouring spout 10, the pouring outlet 25b can be opened by the push-opening operation only when the outer sleeve 30 is in the abutting avoidance direction, which is a limited direction in the direction around the pouring cylinder 22 axis with respect to the spout body 20. It is possible.
The configuration in which the spout 25b can be opened by the push-open operation only when the outer sleeve 30 is in the direction of avoiding abutting against the spout body 20 effectively contributes to the prevention of careless opening of the spout 25b.

詰め替え容器１１０は、注出用スパウト１０が突部同士当接閉止状態で出荷され、注出用スパウト１０の突部同士当接閉止状態を維持したまま店頭にて陳列販売される。
注出用スパウト１０は、万一、詰め替え容器１１０の輸送中の振動等により外側スリーブ３０がスパウト本体２０に対して突部同士当接向きから注出筒部２２軸回り方向に回転されても、外側スリーブ３０がスパウト本体２０に対して突き当て回避向きとならない限り、注出口２５ｂの開放を阻止できる。 The refill container 110 is shipped with the ejection spouts 10 in contact with each other closed, and is displayed and sold at the store while maintaining the protrusions of the dispensing spout 10 in contact with each other.
In the pouring spout 10, even if the outer sleeve 30 is rotated from the direction in which the protrusions are in contact with the spout body 20 in the direction around the pouring cylinder 22 axis due to vibration during transportation of the refill container 110 or the like. As long as the outer sleeve 30 does not abut against the spout body 20 and is in the avoidance direction, the spout 25b can be prevented from opening.

注出用スパウト１０は、詰め替え容器１１０の輸送中の振動等により、外側スリーブ３０がスパウト本体２０に対して突部同士当接向きから注出筒部２２軸回り方向に回転されても、注出口２５ｂの不用意な開放が生じにくい。詰め替え容器１１０は、注出用スパウト１０の注出口２５ｂからの内容物の不用意な注出を生じにくい。 Note that the pouring spout 10 can be used even if the outer sleeve 30 is rotated from the direction in which the protrusions are in contact with the spout body 20 in the direction around the pouring cylinder 22 axis due to vibration during transportation of the refill container 110 or the like. Inadvertent opening of the outlet 25b is unlikely to occur. The refill container 110 is less likely to cause careless pouring of the contents from the pouring outlet 25b of the pouring spout 10.

図９〜図１１に示す注出用スパウト１０は、押し込み限界状態において、外側スリーブ３０のスリーブ基部の前後両側の逃げ部３２ｃにスパウト本体２０の一対の受け側突部２７の側面がそれぞれ当接され、外側スリーブ３０の一対の押し込み規制突部３７の側面（具体的には押し込み規制突部本体３７ｄの側面）にスパウト本体２０のスリーブ受け部２１ｃの側面の逃げ部２１ｈがそれぞれ当接される構成である。
この注出用スパウト１０は、外側スリーブ３０の左右方向がスパウト本体２０の前後方向に揃ったときのみ押し込み開放操作による注出口２５ｂの開放が可能であり、注出口２５ｂの不用意な開放を生じにくい。 In the dispensing spouts 10 shown in FIGS. 9 to 11, the side surfaces of the pair of receiving side protrusions 27 of the spout body 20 abut on the relief portions 32c on both the front and rear sides of the sleeve base of the outer sleeve 30 in the push-in limit state. The side relief portion 21h of the side surface of the sleeve receiving portion 21c of the spout body 20 is brought into contact with the side surface of the pair of push-in regulation protrusions 37 of the outer sleeve 30 (specifically, the side surface of the push-in regulation protrusion body 37d). It is a composition.
The spout 10 for pouring can open the spout 25b by a push-open operation only when the left-right direction of the outer sleeve 30 is aligned with the front-rear direction of the spout body 20, causing careless opening of the spout 25b. Hateful.

詰め替え容器１１０は、注出用スパウト１０を突部同士当接閉止状態とすることで、注出用スパウト１０を覆うオーバーキャップ無しで市場に供給できる。
詰め替え容器１１０は、突部同士当接閉止状態とした注出用スパウト１０に注出用スパウト１０を覆うオーバーキャップを装着した状態で市場に供給しても良い。 The refill container 110 can be supplied to the market without an overcap covering the dispensing spout 10 by closing the ejection spouts 10 in contact with each other.
The refill container 110 may be supplied to the market with an overcap covering the dispensing spout 10 attached to the dispensing spout 10 in which the protrusions are in contact with each other and closed.

注出用スパウト１０は、外側スリーブ３０のスパウト本体２０に対する突き当て回避向きが、注出筒部２２軸回り方向に設定された範囲（例えば注出筒部２２軸線回りの角度範囲）である構成も採用可能である。 The pouring spout 10 has a configuration in which the abutting avoidance direction of the outer sleeve 30 with respect to the spout body 20 is a range set in the direction around the pouring cylinder 22 axis (for example, an angle range around the pouring cylinder 22 axis). Can also be adopted.

注出用スパウト１０は、スパウト本体２０のスリーブ受け部２１ｃの前後両側の側面に突部距離円筒面３７ｓ（図１２参照）の内側に位置する領域である逃げ部（突部逃げ領域）が確保され、且つ、外側スリーブ３０のスリーブ基部の前後両側の側面に受け側突部距離円筒面２７ｓ（図１３参照）の内側に位置する領域である逃げ部（受け側突部逃げ領域）が確保された構成（以下、逃げ領域確保構造、とも言う）も採用可能である。 The pouring spout 10 has a relief portion (protrusion relief region) which is a region located inside the protrusion distance cylindrical surface 37s (see FIG. 12) on both front and rear side surfaces of the sleeve receiving portion 21c of the spout body 20. In addition, a relief portion (reception side protrusion relief region), which is a region located inside the receiving side protrusion distance cylindrical surface 27s (see FIG. 13), is secured on both front and rear side surfaces of the sleeve base of the outer sleeve 30. A configuration (hereinafter, also referred to as an escape area securing structure) can be adopted.

スパウト本体２０のスリーブ受け部２１ｃの突部逃げ領域は、その全体にわたって、押し込み限界状態の注出用スパウト１０の外側スリーブ３０の押し込み規制突部３７との間にクリアランスを確保可能に形成される。
外側スリーブ３０のスリーブ基部の受け側突部逃げ領域は、その全体にわたって、押し込み限界状態の注出用スパウト１０のスパウト本体２０の受け側突部２７との間にクリアランスを確保可能に形成される。 The protrusion escape region of the sleeve receiving portion 21c of the spout body 20 is formed so as to ensure a clearance with the push-restriction protrusion 37 of the outer sleeve 30 of the ejection spout 10 in the push-in limit state over the entire region. ..
The receiving side protrusion escape region of the sleeve base of the outer sleeve 30 is formed so as to ensure a clearance with the receiving side protrusion 27 of the spout body 20 of the ejection spout 10 in the push-in limit state over the entire area. ..

逃げ領域確保構造を有する注出用スパウト１０は、押し込み限界状態としたときに、スパウト本体２０のスリーブ受け部２１ｃの突部逃げ領域と外側スリーブ３０の押し込み規制突部本体３７ｄとの間のクリアランス、及び外側スリーブ３０のスリーブ突部の受け側突部逃げ領域とスパウト本体２０の受け側突部２７との間のクリアランス、によって、外側スリーブ３０にスパウト本体２０に対する注出筒部２２軸回り方向の回転可能範囲を確保する。
逃げ領域確保構造を有する注出用スパウト１０は、外側スリーブ３０にスパウト本体２０に対する注出筒部２２軸回り方向の回転可能範囲によって、外側スリーブ３０のスパウト本体２０に対する突き当て回避向きを注出筒部２２軸回り方向に設定された範囲で確保できる。 The ejection spout 10 having a relief area securing structure has a clearance between the protrusion relief area of the sleeve receiving portion 21c of the spout body 20 and the push-restriction protrusion body 37d of the outer sleeve 30 when the push-in limit state is reached. Due to the clearance between the receiving side protrusion escape area of the sleeve protrusion of the outer sleeve 30 and the receiving side protrusion 27 of the spout body 20, the outer sleeve 30 is provided with the pouring cylinder portion 22 in the axial direction with respect to the spout body 20. Secure the rotatable range of.
The pouring spout 10 having a relief area securing structure pours out the outer sleeve 30 from the outer sleeve 30 in the direction of avoiding contact with the spout body 20 according to the rotatable range of the pouring cylinder portion 22 with respect to the spout body 20 in the axial direction. It can be secured within the range set in the direction around the 22nd axis of the tubular portion.

但し、注出用スパウト１０は、スパウト本体２０のスリーブ受け部２１ｃが左右両側に突部距離円筒面３７ｓ外側に位置する部分を有し、且つ外側スリーブ３０のスリーブ基部の左右両側に受け側突部距離円筒面２７ｓ外側に位置する部分を有する構成を採用する。
外側スリーブ３０のスパウト本体２０に対する突き当て回避向きの範囲は、押し込み限界状態とした注出用スパウト１０における外側スリーブ３０のスパウト本体２０に対する注出筒部２２軸回り方向の回転可能範囲に限定された範囲である。 However, the pouring spout 10 has a portion where the sleeve receiving portion 21c of the spout body 20 is located on both the left and right sides of the cylindrical surface 37s, and the receiving side protrusions on both the left and right sides of the sleeve base of the outer sleeve 30. Part distance A configuration having a portion located outside the cylindrical surface 27s is adopted.
The range of the outer sleeve 30 in the direction of avoiding abutting against the spout body 20 is limited to the rotatable range of the outer sleeve 30 with respect to the spout body 20 in the direction around the spout cylinder 22 of the pouring spout 10 in the push-in limit state. It is a range.

逃げ領域確保構造を有する注出用スパウト１０は、例えば、図１２に示すスパウト本体２０についてスリーブ受け部２１ｃの前後の前後側面２１ｇの注出筒部２２軸線からの距離を突部距離円筒面３７ｓの湾曲半径に比べて若干小さく変更し、且つ、図１３に示す外側スリーブ３０についてストッパ突板部３２Ａの前後の前後側面３２ｂの注出筒部２２軸線からの距離が受け側突部距離円筒面２７ｓの湾曲半径に比べて若干小さく変更した構成を挙げることができる。 The pouring spout 10 having a relief area securing structure is, for example, the distance from the front and rear side surfaces 21g of the sleeve receiving portion 21c to the front and rear side surfaces 21g of the spout main body 20 shown in FIG. The distance from the front and rear side surfaces 32b of the stopper veneer 32A to the front and rear side surfaces 32b of the stopper veneer 32A is the distance from the receiving cylinder 22 axis for the outer sleeve 30 shown in FIG. It can be mentioned that the configuration is slightly smaller than the radius of curvature of.

この構成の注出用スパウト１０においては、スパウト本体２０のスリーブ受け部２１ｃの前後の前後側面２１ｇの左右方向の一部または全部によって受け側突部距離円筒面２７ｓの内側に位置する突部逃げ領域が確保され、外側スリーブ３０のストッパ突板部３２Ａの前後の前後側面３２ｂの左右方向の一部または全部によって受け側突部距離円筒面２７ｓの内側に位置する受け側突部逃げ領域が確保される。 In the pouring spout 10 having this configuration, a protrusion escape located inside the receiving side protrusion distance cylindrical surface 27s by a part or all of the front and rear front and rear side surfaces 21g of the sleeve receiving portion 21c of the spout body 20 in the left-right direction. A region is secured, and a receiving side protrusion escape area located inside the receiving side protrusion distance cylindrical surface 27s is secured by a part or all of the front and rear front and rear side surfaces 32b of the stopper protrusion 32A of the outer sleeve 30 in the left-right direction.

逃げ領域確保構造を有する注出用スパウト１０は、例えば、図１５に示すようにスパウト本体２０のスリーブ受け部２１ｃの前後の前後側面２１ｇの左右方向中央部に形成された凹形部２１ｉに突部距離円筒面３７ｓの内側に位置する突部逃げ領域２１ｊが確保され、且つ、図１６に示すように外側スリーブ３０のストッパ突板部３２Ａの前後の前後側面３２ｂの左右方向中央部に形成された凹形部３２ｄに受け側突部距離円筒面２７ｓの内側に位置する受け側突部逃げ領域３２ｅが確保された構成も採用可能である。 As shown in FIG. 15, the pouring spout 10 having a relief area securing structure protrudes into a concave portion 21i formed in the central portion in the left-right direction of the front-rear and front-rear side surfaces 21g of the sleeve receiving portion 21c of the spout main body 20, for example. A protrusion escape region 21j located inside the cylindrical surface 37s is secured, and as shown in FIG. 16, it is formed in the central portion in the left-right direction of the front-rear and front-rear side surfaces 32b of the stopper veneer portion 32A of the outer sleeve 30. It is also possible to adopt a configuration in which the receiving side protrusion escape region 32e located inside the receiving side protrusion distance cylindrical surface 27s is secured in the concave portion 32d.

図５等に示すように、突部同士当接閉止状態の注出用スパウト１０においてスパウト本体２０の受け側突部２７の位置決め凹部２７ｃに位置決め突起３７ｃが挿入される構成は、位置決め凹部２７ｃに収容された位置決め突起３７ｃを位置決め凹部２７ｃから抜き出さない限り、外側スリーブ３０をスパウト本体２０の注出筒部２２に対して軸回り回転させることができない。
突部同士当接閉止状態の注出用スパウト１０においてスパウト本体２０の受け側突部２７の位置決め凹部２７ｃに位置決め突起３７ｃが挿入される構成は、スパウト本体２０の注出筒部２２に対する外側スリーブ３０の不用意な軸回り回転の防止、及び注出口２５ｂの不用意な開放の防止、に有効に寄与する。 As shown in FIG. 5 and the like, in the pouring spout 10 in the state where the protrusions are in contact with each other and closed, the positioning protrusion 37c is inserted into the positioning recess 27c of the receiving side protrusion 27 of the spout body 20 in the positioning recess 27c. Unless the housed positioning protrusion 37c is pulled out from the positioning recess 27c, the outer sleeve 30 cannot be rotated about the axis with respect to the pouring cylinder portion 22 of the spout body 20.
In the pouring spout 10 in the state where the protrusions are in contact with each other and closed, the positioning protrusion 37c is inserted into the positioning recess 27c of the receiving side protrusion 27 of the spout body 20. It effectively contributes to the prevention of careless rotation around the axis of 30 and the careless opening of the spout 25b.

図１０に示すように、注出用スパウト１０が注出口開放状態となったとき、詰め替え容器１１０内の内容物は注出用スパウト１０の内容物流路２５の複数の分割流路２５ｃの１以上を介して包装容器１２０へ流入、充填される。 As shown in FIG. 10, when the pouring spout 10 is in the spout open state, the content in the refill container 110 is one or more of the plurality of divided flow paths 25c of the content flow path 25 of the pouring spout 10. It flows into the packaging container 120 and is filled.

図９〜図１１に示すように、包装容器１２０の口首部１２１に挿入した注出用スパウト１０の外側スリーブ本体３１と口首部１２１内周面との間に確保された隙間である通気路１２の口首部１２１先端側の端を、以下、上部開口部、とも言う。
通気路１２の上部開口部の一部は、口首部１２１先端に当接された外側スリーブ３０のストッパ突片３２によって覆われる。 As shown in FIGS. 9 to 11, the ventilation passage 12 is a gap secured between the outer sleeve main body 31 of the pouring spout 10 inserted into the mouth portion 121 of the packaging container 120 and the inner peripheral surface of the mouth portion 121. The end of the mouth portion 121 on the distal end side is also hereinafter referred to as an upper opening.
A part of the upper opening of the air passage 12 is covered with a stopper projecting piece 32 of the outer sleeve 30 that is in contact with the tip of the mouth portion 121.

図１１に示すように、外側スリーブ３０のスリーブ基部の前後方向寸法（幅寸法。ストッパ突板部３２Ａの前後方向寸法）は、包装容器口首部１２１内径に比べて小さい。このため、通気路１２の上部開口部の、口首部１２１先端に当接された外側スリーブ３０のストッパ突片３２によって覆われた部分以外は開口状態が維持される。 As shown in FIG. 11, the front-rear direction dimension (width dimension. The front-rear direction dimension of the stopper veneer portion 32A) of the sleeve base of the outer sleeve 30 is smaller than the inner diameter of the packaging container mouth portion 121. Therefore, the open state is maintained except for the portion of the upper opening of the ventilation passage 12 covered by the stopper projecting piece 32 of the outer sleeve 30 that is in contact with the tip of the mouth portion 121.

図９〜図１１において、詰め替え容器１１０から包装容器１２０の容器本体１２４への内容物の充填が進行すると、それに伴い容器本体１２４内の空気が容器本体１２４から押し出される。容器本体１２４から押し出された空気Ｇは、包装容器口首部１２１内の通気路１２を通って通気路１２の上部開口部の開口部分から包装容器１２０外へ排気される。
その結果、詰め替え容器１１０から包装容器１２０の容器本体１２４への内容物の充填を円滑に進行できる。 In FIGS. 9 to 11, as the filling of the contents from the refill container 110 into the container body 124 of the packaging container 120 progresses, the air in the container body 124 is pushed out from the container body 124 accordingly. The air G extruded from the container body 124 is exhausted to the outside of the packaging container 120 from the opening portion of the upper opening of the ventilation passage 12 through the ventilation passage 12 in the packaging container mouth portion 121.
As a result, the filling of the contents from the refill container 110 to the container body 124 of the packaging container 120 can proceed smoothly.

図９〜図１１に示すように、注出用スパウト１０の外側スリーブ３０について、スパウト挿入操作にて主筒部３３を挿入した包装容器口首部１２１の先端にストッパ突片３２を当接させた状態を、以下、当接セット状態、とも言う。
図９〜図１１等に示す注出用スパウト１０の外側スリーブ主筒部３３の軸線方向寸法は、包装容器１２０の口首部１２１の軸線方向寸法よりも大きい。このため、スパウト挿入操作にて包装容器１２０に対して当接セット状態とした外側スリーブ３０の主筒部３３は、包装容器口首部１２１内側を貫通して、包装容器１２０の容器本体１２４の内側領域に到達、挿入される。外側スリーブ主筒部３３の先端は包装容器口首部１２１の下方に配置される。 As shown in FIGS. 9 to 11, regarding the outer sleeve 30 of the spout for dispensing 10, the stopper projecting piece 32 was brought into contact with the tip of the mouthpiece 121 of the packaging container into which the main cylinder 33 was inserted by the spout insertion operation. Hereinafter, the state is also referred to as a contact set state.
The axial dimension of the outer sleeve main cylinder portion 33 of the pouring spout 10 shown in FIGS. 9 to 11 and the like is larger than the axial dimension of the mouth portion 121 of the packaging container 120. Therefore, the main cylinder portion 33 of the outer sleeve 30 that has been set in contact with the packaging container 120 by the spout insertion operation penetrates the inside of the packaging container mouth portion 121 and is inside the container body 124 of the packaging container 120. The area is reached and inserted. The tip of the outer sleeve main cylinder portion 33 is arranged below the packaging container mouth portion 121.

図９〜図１１に示すように、外側スリーブ３０を包装容器１２０に対して当接セット状態としたときには、外側スリーブ主筒部３３とともにその内側のスパウト本体２０の注出用突部２６も容器本体１２４の内側に到達、挿入される。
注出用スパウト１０の内容物流路２５の注出口２５ｂは、スパウト挿入操作後の押し込み開放操作によって、包装容器１２０の口首部１２１よりも下方にて開放される。 As shown in FIGS. 9 to 11, when the outer sleeve 30 is in the contact set state with respect to the packaging container 120, the outer sleeve main cylinder portion 33 and the ejection protrusion 26 of the spout main body 20 inside the outer sleeve main cylinder portion 20 are also containers. It reaches the inside of the main body 124 and is inserted.
The pouring outlet 25b of the content flow path 25 of the pouring spout 10 is opened below the mouth portion 121 of the packaging container 120 by the push-opening operation after the spout insertion operation.

図９〜図１１に示すように、押し込み開放操作によって注出用スパウト１０の注出口２５ｂが包装容器１２０の口首部１２１よりも下方に位置して開放される構成であれば、注出口２５ｂから放出された内容物が包装容器口首部１２１内に滞留することが無い。注出用スパウト１０の注出口２５ｂが包装容器１２０の口首部１２１よりも下方にて開放される構成であれば、注出口２５ｂから放出された内容物が包装容器１２０の容器本体１２４内の空気Ｇの通気路１２を介した排気の障害になることを回避できる。したがって、容器本体１２４内の空気Ｇの通気路１２を介した排気を安定且つ円滑に行える。その結果、注出用スパウト１０の注出口２５ｂから包装容器１２０の容器本体１２４への内容物の注出、充填を円滑かつ短時間で行なうことが可能となる。 As shown in FIGS. 9 to 11, if the pouring outlet 25b of the pouring spout 10 is located below the mouth portion 121 of the packaging container 120 and is opened by the push-open operation, the pouring outlet 25b is used. The released contents do not stay in the mouthpiece 121 of the packaging container. If the spout 25b of the pouring spout 10 is opened below the mouth portion 121 of the packaging container 120, the contents discharged from the spout 25b are the air in the container body 124 of the packaging container 120. It is possible to avoid an obstacle to exhaust through the ventilation path 12 of G. Therefore, the air G in the container body 124 can be stably and smoothly exhausted through the air passage 12. As a result, the contents can be smoothly and quickly filled from the pouring outlet 25b of the pouring spout 10 to the container body 124 of the packaging container 120.

なお、注出用スパウト１０は、外側スリーブ主筒部３３の軸線方向寸法が包装容器口首部１２１の軸線方向寸法よりも短い外側スリーブ３０を用いた構成も採用可能である。 The pouring spout 10 can also adopt a configuration using an outer sleeve 30 in which the axial dimension of the outer sleeve main cylinder portion 33 is shorter than the axial dimension of the packaging container mouth portion 121.

詰め替え容器１１０の注出用スパウト１０は、包装容器口首部１２１に対して挿脱可能である。
詰め替え容器１１０は、包装容器１２０への内容物注出により内部の内容物が無くなったら、上向き状態の包装容器１２０から上方へ引き上げて注出用スパウト１０を包装容器１２０から引き抜くだけで包装容器１２０から簡単に撤去できる。 The pouring spout 10 of the refill container 110 is removable with respect to the mouthpiece 121 of the packaging container.
When the contents of the refill container 110 are exhausted by pouring the contents into the packaging container 120, the refill container 110 is simply pulled upward from the packaging container 120 in the upward state and the spout 10 for dispensing is pulled out from the packaging container 120. Can be easily removed from.

注出口開放状態の注出用スパウト１０は、外側スリーブ３０をスパウト本体２０に対して嵌合位置に引き戻すことで、突部同士当接閉止状態に復帰させることができる。
詰め替え容器１１０は、注出口開放状態の注出用スパウト１０を突部同士当接閉止状態に復帰させることで、内部に残液等の内容物が存在する場合でも、内容物流路２５の注出口２５ｂからの内容物の漏出を防いだ状態で保管することができる。 The pouring spout 10 in the pouring outlet open state can be returned to the state in which the protrusions are in contact with each other and closed by pulling the outer sleeve 30 back to the fitting position with respect to the spout body 20.
The refill container 110 returns the pouring spout 10 in the open spout state to the closed state in which the protrusions are in contact with each other, so that the spout of the content flow path 25 is discharged even if there is a content such as residual liquid inside. It can be stored in a state where the contents are prevented from leaking from 25b.

By being detachably housed, the axial rotation with respect to the pouring cylinder portion 22 is restricted. The outer sleeve 30 rotates axially with respect to the pouring cylinder portion 22 of the spout body 20 in a state where the positioning protrusion 37c at the tip of the push-in regulation protrusion 37 is pulled out from the positioning recess 27c of the sleeve receiving portion 21c of the mounting portion 21. It is possible.

図１９に示すように、押し込み規制突部３７は押し込み規制突部本体３７ｄの突端面の一部から突出する位置決め突起３７ｃが存在せず、その全体が押し込み規制突部本体３７ｄである構成も採用可能である。
図１９に示す押し込み規制突部３７の先端面は断面部分円状で外側スリーブ３０左右方向に延在する部分円筒面状になっている。但し、押し込み規制突部３７の先端面は外側スリーブ主筒部３３軸線に垂直の平坦面、先端が尖った形状の尖鋭形状等も採用可能である。 As shown in FIG. 19, the push-in regulation protrusion 37 does not have a positioning protrusion 37c protruding from a part of the tip surface of the push-regulation protrusion main body 37d, and the entire push-regulation protrusion main body 37d is adopted. It is possible.
The tip surface of the push-in regulation protrusion 37 shown in FIG. 19 has a circular cross section and a partial cylindrical surface extending in the left-right direction of the outer sleeve 30. However, as the tip surface of the push-in regulation protrusion 37, a flat surface perpendicular to the 33 axis of the outer sleeve main cylinder portion, a sharp shape with a sharp tip, or the like can be adopted.

第２受け部の規制突部受け部は、第１受け部側から押し込み規制突部が当接されることで外側スリーブ３０をスパウト本体２０に対して注出筒部２２軸線方向において嵌合位置に位置決めできるものであれば良い。この点、規制突部受け部は、必ずしも、受け側突部２７や位置決め凹部２７ｃ（具体的には位置決め凹部２７ｃ内面）である必要はなく、種々構成を採用できる。
規制突部受け部は、外側スリーブ３０のスパウト本体２０の注出筒部２２に対する軸回り回転を規制しない構成も採用可能である。規制突部受け部は、例えば第２受け部の第１受け部側に形成された平坦面等であっても良い。 The regulation protrusion receiving portion of the second receiving portion is in a position where the outer sleeve 30 is fitted to the spout body 20 in the axial direction of the ejection cylinder portion 22 by pushing the regulation protrusion portion from the first receiving portion side. Anything that can be positioned at In this respect, the regulation protrusion receiving portion does not necessarily have to be the receiving side protrusion 27 or the positioning recess 27c (specifically, the inner surface of the positioning recess 27c), and various configurations can be adopted.
The regulation protrusion receiving portion can also adopt a configuration that does not regulate the axial rotation of the spout body 20 of the outer sleeve 30 with respect to the pouring cylinder portion 22. The regulation protrusion receiving portion may be, for example, a flat surface formed on the first receiving portion side of the second receiving portion.

注出用スパウト１０は、第２受け部の側面に、注出筒部２２の軸線を中心とし注出筒部２２の軸線と押し込み規制突部３７との間の離間距離を半径とする仮想円筒面である突部距離円筒面３７ｓ上あるいは突部距離円筒面３７ｓの内側に位置する部分である突部逃げ部が確保され、第２受け部は押し込み規制突部３７が突部逃げ部の側方に配置された状態で第１受け部と当接可能とされている構成を採用できる。 The dispensing spout 10 is a virtual cylinder on the side surface of the second receiving portion, with the axis of the dispensing cylinder 22 as the center and the distance between the axis of the dispensing cylinder 22 and the push-in regulation protrusion 37 as the radius. A protrusion relief portion, which is a portion located on the protrusion distance cylindrical surface 37s, which is a surface, or inside the protrusion distance cylindrical surface 37s, is secured, and the push-in regulation protrusion 37 is on the side of the protrusion relief portion in the second receiving portion. It is possible to adopt a configuration in which the first receiving portion can be brought into contact with the first receiving portion while being arranged on the side.

第２受け部の規制突部受け部が受け側突部である場合は、第１受け部の側面に、注出筒部２２の軸線を中心とし注出筒部２２の軸線と受け側突部との間の離間距離を半径とする仮想円筒面である受け側突部距離円筒面２７ｓ上あるいは受け側突部距離円筒面２７ｓの内側に位置する部分である受け側突部逃げ部を確保する。この場合、注出用スパウト１０は、押し込み規制突部３７が突部逃げ部の側方に配置され且つ規制突部受け部が受け側突部逃げ部の側方に配置された状態で第２受け部を第１受け部と当接可能とされる。 Regulation of the second receiving part When the receiving part is the receiving side protrusion, the axis of the dispensing cylinder 22 and the receiving side protrusion centering on the axis of the dispensing cylinder 22 are on the side surface of the first receiving part. Receiving side protrusion distance which is a virtual cylindrical surface whose radius is the distance between the receiving side protrusion distance The receiving side protrusion escape portion which is a portion located on the cylindrical surface 27s or inside the receiving side protrusion distance cylindrical surface 27s is secured. ..
