特開２０１６－１５９９４２号公報Japanese Unexamined Patent Publication No. 2016-159942

上記のような注出容器においては、容器本体内の内容物の残量が少なくなると、容器本体を倒立等させた際に、収容筒部の容器本体側の開口部が内容物から露出した状態となる場合がある。この場合、容器本体をスクイズ変形させる等によって容器本体内の圧力を上昇させて内容物を注出孔から注出させようとする場合に、容器本体内の空気が収容筒部から注出孔に抜け出てしまい、容器本体内の圧力を上昇させることができなくなる。そのため、容器本体の口部を開放可能に閉塞する注出弁を開放させることができなり、容器本体内に内容物が残っていても注出孔から内容物を注出できなくなる。したがって、容器本体内に内容物が比較的多く残留しやすい問題があった。 In the above-mentioned pouring container, when the remaining amount of the contents in the container body is low, the opening of the container body on the container body side is exposed from the contents when the container body is inverted. May be. In this case, when the pressure inside the container body is increased by deforming the container body by squeeze and the contents are to be poured out from the pouring hole, the air inside the container body flows from the accommodating cylinder to the pouring hole. It will come out and the pressure inside the container body cannot be increased. Therefore, the pouring valve that closes the mouth of the container body so as to be open can be opened, and even if the contents remain in the container body, the contents cannot be poured out from the pouring hole. Therefore, there is a problem that a relatively large amount of contents tend to remain in the container body.

本発明の一つの態様は、上記事情に鑑みて、容器本体内に残留する内容物の量を低減できる注出容器を提供することを目的の一つとする。 One aspect of the present invention is to provide a pouring container capable of reducing the amount of contents remaining in the container body in view of the above circumstances.

本発明の注出容器の一つの態様は、内容物が収容されると共に内容物の減少に伴いしぼみ変形する内容器、および前記内容器が内装された外容器を有する容器本体と、前記容器本体の口部に装着される注出キャップと、を備え、前記外容器には、前記内容器との間に外気を吸入する吸気孔が形成され、前記注出キャップは、注出孔が形成された天壁部を有する有頂筒状のキャップ本体と、前記容器本体の内部と前記注出孔とを連通する流通孔が形成され、前記口部を閉塞する中栓部と、前記流通孔を開放可能に閉塞する注出弁と、前記キャップ本体の中心軸方向に延びる筒状に形成され、前記容器本体側の端部が前記容器本体の内部に位置する開口部であり、かつ、内部が前記注出孔と連通する収容筒部と、前記収容筒部の内部に前記中心軸方向に摺動自在に収容された摺動体と、を有し、前記収容筒部は、収容筒部本体と、前記収容筒部本体の前記容器本体側と逆側の端部に前記収容筒部本体の周方向に沿って互いに隙間を空けて形成された複数の係止片と、を有し、前記複数の係止片は、前記中栓部のうち前記流通孔が形成された部分よりも前記容器本体側と逆側に位置し、前記収容筒部の内部と前記注出孔とは、前記係止片同士の周方向の隙間を通じて連通していることを特徴とする。 One aspect of the pouring container of the present invention is a container body having an inner container in which the contents are accommodated and deflated and deformed as the contents decrease, and an outer container in which the inner container is contained, and the container body. The outer container is provided with a pouring cap attached to the mouth portion of the container, and an intake hole for sucking outside air is formed between the outer container and the inner container, and the pouring cap is formed with a pouring hole. A ridged tubular cap body having a top wall portion, a flow hole for communicating the inside of the container body and the pouring hole are formed, and an inner plug portion for closing the mouth portion and the flow hole are formed. An dispenser valve that can be opened and closed, and an opening that is formed in a tubular shape extending in the central axis direction of the cap body and whose end on the container body side is located inside the container body, and that the inside is It has an accommodating cylinder portion communicating with the pouring hole and a sliding body slidably accommodated in the center axis direction inside the accommodating cylinder portion, and the accommodating cylinder portion is the main body of the accommodating cylinder portion. A plurality of locking pieces formed at an end of the container body of the container body opposite to the container body side with a gap from each other along the circumferential direction of the container body, and the plurality of lock pieces. The locking piece is located on the side opposite to the container body side of the inner plug portion where the flow hole is formed, and the inside of the storage cylinder portion and the pouring hole are locked. It is characterized by communicating through a gap in the circumferential direction between the pieces.

本発明の注出容器の一つの態様によれば、収容筒部は、収容筒部本体の周方向に沿って互いに隙間を空けて形成された複数の係止片を有し、複数の係止片は、中栓部のうち流通孔が形成された部分よりも容器本体４側と逆側に位置する。そのため、複数の係止片によって、収容筒部全体の上下方向の寸法を維持しつつ、中栓部から容器本体側に突出する収容筒部の突出長さを小さくできる。これにより、収容筒部全体が中栓部から容器本体側に突出している場合に比べて、収容筒部の開口部の位置を容器本体側と逆側に配置することができる。したがって、容器本体内の内容物の量が比較的少なくなっても、注出容器を倒立させた際に開口部が空気に露出しにくくできる。そのため、本発明の注出容器の一つの態様によれば、収容筒部内における摺動体のストローク量を確保してサックバック機能を好適に維持しつつ、容器本体内に残留する内容物の量を低減できる。 According to one aspect of the pouring container of the present invention, the accommodating cylinder portion has a plurality of locking pieces formed so as to be spaced apart from each other along the circumferential direction of the accommodating cylinder portion main body, and has a plurality of locking pieces. The piece is located on the side opposite to the container body 4 side of the inner plug portion where the flow hole is formed. Therefore, the plurality of locking pieces can reduce the protruding length of the storage cylinder portion that protrudes from the inner plug portion toward the container body while maintaining the vertical dimension of the entire storage cylinder portion. As a result, the position of the opening of the storage cylinder portion can be arranged on the opposite side to the container main body side as compared with the case where the entire storage cylinder portion protrudes from the inner plug portion toward the container body side. Therefore, even if the amount of the contents in the container body is relatively small, the opening can be less likely to be exposed to the air when the pouring container is inverted. Therefore, according to one aspect of the pouring container of the present invention, the amount of contents remaining in the container body can be reduced while ensuring the stroke amount of the sliding body in the accommodating cylinder portion and appropriately maintaining the suckback function. Can be reduced.

また、本発明の注出容器の一つの態様によれば、収容筒部の内部と注出孔とは、係止片同士の周方向の隙間を通じて連通している。そのため、収容筒部内に流入した内容物を、係止片同士の周方向の隙間を介して、注出孔へと好適に流すことができる。したがって、本発明の注出容器の一つの態様によれば、容器本体内に残留する内容物の量を低減でき、かつ、収容筒部内を介した内容物の注出を円滑に行うことができる。係止片同士の周方向の隙間の大きさを調整することにより、収容筒部内から係止片同士の周方向の隙間を通じて注出される内容物の量を調整可能である。 Further, according to one aspect of the pouring container of the present invention, the inside of the accommodating cylinder portion and the pouring hole communicate with each other through a gap in the circumferential direction between the locking pieces. Therefore, the contents that have flowed into the accommodating cylinder can be suitably flowed to the pouring hole through the gap in the circumferential direction between the locking pieces. Therefore, according to one aspect of the dispensing container of the present invention, the amount of the contents remaining in the container body can be reduced, and the contents can be smoothly dispensed through the inside of the storage cylinder. .. By adjusting the size of the circumferential gap between the locking pieces, it is possible to adjust the amount of the contents poured out from inside the accommodating cylinder through the circumferential gap between the locking pieces.

前記中栓部は、前記流通孔が形成されたベース部を有し、前記収容筒部本体は、前記ベース部から前記容器本体側と逆側に突出する部分を有し、前記収容筒部本体のうち前記ベース部から前記容器本体側と逆側に突出する部分の周囲には、前記収容筒部本体を囲む環状であり、前記流通孔に連通する環状空洞部が形成され、前記注出弁は、前記環状空洞部を前記容器本体側と逆側から開放可能に閉塞することによって、前記流通孔を開放可能に閉塞している構成としてもよい。
この構成によれば、容器本体をスクイズ変形させた際、注出弁は、環状空洞部内の内容物または空気を介して開放される向きに力を受ける。これにより、例えば注出弁によって流通孔を直接的に閉塞する場合に比べて、注出弁の受圧面積を大きくしやすい。したがって、容器本体内の空気が収容筒部の開口部から注出孔へと抜け出る場合であっても、外容器をある程度強く押圧する等により容器本体を比較的大きくスクイズ変形させることで、注出弁を開放しやすくできる。そのため、注出容器を倒立させた際に収容筒部の開口部が空気に露出した場合であっても、注出弁を開放させて、流通孔を通じて内容物を注出しやすくできる。これにより、容器本体内に残留する内容物の量をより低減できる。 The inner plug portion has a base portion in which the flow hole is formed, and the storage cylinder portion main body has a portion protruding from the base portion to the side opposite to the container main body side, and the storage cylinder portion main body. Around the portion of the base portion that protrudes from the base portion to the side opposite to the container main body side, an annular cavity portion that is an annular shape surrounding the storage cylinder portion main body and communicates with the distribution hole is formed, and the injection valve is formed. May be configured to openably close the flow hole by closing the annular cavity portion so as to be openable from the side opposite to the container body side.
According to this configuration, when the container body is squeeze-deformed, the ejection valve receives a force in a direction of being opened through the contents or air in the annular cavity. As a result, it is easy to increase the pressure receiving area of the dispensing valve as compared with the case where the flow hole is directly closed by, for example, the dispensing valve. Therefore, even when the air inside the container body escapes from the opening of the storage cylinder to the pouring hole, the container body is squeeze-deformed relatively large by pressing the outer container strongly to some extent to perform pouring. The valve can be opened easily. Therefore, even when the opening of the accommodating cylinder is exposed to air when the pouring container is inverted, the pouring valve can be opened to facilitate pouring of the contents through the distribution hole. As a result, the amount of contents remaining in the container body can be further reduced.

前記中栓部は、前記収容筒部から径方向の外側に広がり前記容器本体の内部に面する平坦面を有し、前記流通孔は、前記平坦面に開口している構成としてもよい。
この構成によれば、流通孔内に内容物を流入させやすくでき、流通孔を通じて内容物を注出させやすくできる。これにより、容器本体内に残留する内容物の量をより低減できる。 The inner plug portion may have a flat surface extending radially outward from the storage cylinder portion and facing the inside of the container body, and the flow hole may be configured to open to the flat surface.
According to this configuration, the contents can be easily flowed into the distribution hole, and the contents can be easily poured out through the distribution hole. As a result, the amount of contents remaining in the container body can be further reduced.

本発明の一つの態様によれば、容器本体内に残留する内容物の量を低減できる注出容器が提供される。 According to one aspect of the present invention, there is provided a pouring container capable of reducing the amount of contents remaining in the container body.

The plurality of locking pieces 72 are located on the opposite side (upper side) of the container body 4 side from the portion of the inner plug portion 10 where the flow hole 11e is formed, that is, the inner base portion 11b. The inside of the accommodating cylinder 70 and the ejection hole 26 communicate with each other through a gap in the circumferential direction between the locking pieces 72. As shown in FIG. 3, the plurality of locking pieces 72 are arranged at equal intervals, for example, along the circumferential direction. For example, four locking pieces 72 are provided. The gap between the locking pieces 72 adjacent to each other in the circumferential direction is, for example, equal to or larger than the circumferential dimension of the locking pieces 72. The gap between the locking pieces 72 adjacent to each other in the circumferential direction is smaller than the diameter of the sliding body 80.

係止片７２は、図１に示すように、収容筒部本体７１から上方に延びている。より詳細には、係止片７２は、収容筒部本体７１の径方向内周縁部７１ａから上方に延びている。係止片７２の上下方向の寸法は、例えば、摺動体８０の半径よりも大きい。係止片７２の上下方向の寸法は、例えば、摺動体８０の直径と同じである。係止片７２は、収容筒部本体７１から上方に延びる延伸部７２ａと、延伸部７２ａの上側の端部から径方向内側に突出する突起部７２ｂと、を有する。 As shown in FIG. 1, the locking piece 72 extends upward from the accommodating cylinder portion main body 71. More specifically, the locking piece 72 extends upward from the radial inner peripheral edge portion 71a of the accommodating cylinder portion main body 71. The vertical dimension of the locking piece 72 is, for example, larger than the radius of the sliding body 80. The vertical dimension of the locking piece 72 is, for example, the same as the diameter of the sliding body 80. The locking piece 72 has a stretched portion 72a extending upward from the accommodating cylinder portion main body 71, and a protruding portion 72b protruding radially inward from the upper end portion of the stretched portion 72a.

延伸部７２ａの上側の端部は、係止片７２の上側の端部である。延伸部７２ａの上側の端部は、例えば、支持突起２５の下側の端部と上下方向においてほぼ同じ位置に位置している。複数の係止片７２の各延伸部７２ａによって囲まれる内側には、摺動体８０を上下方向に移動可能に収容可能である。
複数の係止片７２の各突起部７２ｂは、上下方向に見て摺動体８０と重なっている。突起部７２ｂによって摺動体８０が収容筒部７０の上側の開口から抜け出ることが規制されている。 The upper end of the stretched portion 72a is the upper end of the locking piece 72. The upper end of the stretched portion 72a is located, for example, at substantially the same position in the vertical direction as the lower end of the support protrusion 25. The sliding body 80 can be accommodated in the inside surrounded by the extending portions 72a of the plurality of locking pieces 72 so as to be movable in the vertical direction.
Each protrusion 72b of the plurality of locking pieces 72 overlaps with the sliding body 80 when viewed in the vertical direction. The protrusion 72b regulates the sliding body 80 from coming out of the upper opening of the accommodating cylinder 70.

摺動体８０は、収容筒部７０内に上下方向に移動可能に収容され、弁座部７０ａの内周面上に上方に向けて離反可能に着座している。図示の例では、摺動体８０は、球状に形成されたいわゆるボール弁とされている。摺動体８０の外径は、収容筒部７０のうち弁座部７０ａよりも上方に位置する部分の内径よりも小さい。これにより、収容筒部７０の内周面と摺動体８０との間には僅かな隙間が設けられ、当該隙間を介して収容筒部７０内を内容物または空気が流通可能となっている。 The sliding body 80 is accommodated in the accommodating cylinder portion 70 so as to be movable in the vertical direction, and is seated on the inner peripheral surface of the valve seat portion 70a so as to be detachable upward. In the illustrated example, the sliding body 80 is a so-called ball valve formed in a spherical shape. The outer diameter of the sliding body 80 is smaller than the inner diameter of the portion of the accommodating cylinder portion 70 located above the valve seat portion 70a. As a result, a slight gap is provided between the inner peripheral surface of the accommodating cylinder 70 and the sliding body 80, and the contents or air can flow through the accommodating cylinder 70 through the gap.

摺動体８０は、内容物を注出するにあたって注出容器１を例えば傾倒または上下反転させたときに、自重により弁座部７０ａから離れる向きに移動し、注出容器１を元の正立姿勢に戻したときに、自重により弁座部７０ａに近付く向きに移動する。これにより、内容物の注出後、注出容器１を元の正立姿勢に戻したときに、ベース部１１の上方に残留した内容物を収容筒部７０の内部に引き込むことができ、いわゆるサックバック効果により液だれを回避することが可能とされている。 When the dispensing container 1 is tilted or turned upside down, for example, the sliding body 80 moves in a direction away from the valve seat portion 70a due to its own weight, and the dispensing container 1 is placed in its original upright posture. When it is returned to, it moves in a direction approaching the valve seat portion 70a due to its own weight. As a result, when the pouring container 1 is returned to the original upright posture after pouring out the contents, the contents remaining above the base portion 11 can be drawn into the inside of the accommodating cylinder portion 70, so-called. It is possible to avoid dripping due to the suckback effect.

摺動体８０は、例えば、弁座部７０ａから離れる向きに移動した際、係止片７２の突起部７２ｂに接触するよりも先に、支持突起２５の先端部（下端部）に接触する。本実施形態においては、支持突起２５の先端部と係止片７２の下端部との上下方向の距離は、摺動体８０の半径よりも大きい。そのため、図１において二点鎖線で示すように摺動体８０が支持突起２５に接触するまで上方に移動した場合には、球状の摺動体８０の中心が係止片７２の下端部よりも上方に位置する。これにより、収容筒部本体７１の内部のうち摺動体８０よりも下方に位置する部分と係止片７２同士の周方向の隙間とが、摺動体８０と収容筒部７０の内周面との隙間を介さずに連通する。支持突起２５に接触した状態において摺動体８０は、複数の係止片７２の内側に収容された状態となる。 For example, when the sliding body 80 moves away from the valve seat portion 70a, the sliding body 80 comes into contact with the tip end portion (lower end portion) of the support protrusion 25 before contacting the protrusion portion 72b of the locking piece 72. In the present embodiment, the vertical distance between the tip end portion of the support protrusion 25 and the lower end portion of the locking piece 72 is larger than the radius of the sliding body 80. Therefore, when the sliding body 80 moves upward until it comes into contact with the support projection 25 as shown by the alternate long and short dash line in FIG. 1, the center of the spherical sliding body 80 is above the lower end of the locking piece 72. To position. As a result, the portion of the inside of the accommodating cylinder portion 71 that is located below the sliding body 80 and the gap between the locking pieces 72 in the circumferential direction are formed between the sliding body 80 and the inner peripheral surface of the accommodating cylinder portion 70. Communicate without going through a gap. The sliding body 80 is housed inside the plurality of locking pieces 72 in a state of being in contact with the support protrusion 25.

弁部材６０は、中栓部１０とキャップ本体２０の天壁部２２との上下方向の間に設けられている。本実施形態において弁部材６０は、注出弁４０と、空気弁５０と、を有している。
なお、例えば外気導入孔２３の大きさを小さくする等して、空気弁５０を設けなくても、外容器６をスクイズ変形したときに、外容器６と内容器５との間の空気が外気導入孔２３から実質的に流出しない構成を採用してもよい。 The valve member 60 is provided between the inner plug portion 10 and the top wall portion 22 of the cap body 20 in the vertical direction. In the present embodiment, the valve member 60 has an injection valve 40 and an air valve 50.
Even if the air valve 50 is not provided by reducing the size of the outside air introduction hole 23, for example, when the outer container 6 is squeeze-deformed, the air between the outer container 6 and the inner container 5 becomes the outside air. A configuration that does not substantially flow out from the introduction hole 23 may be adopted.

注出弁４０は、流通孔１１ｅを開放可能に閉塞する。これにより、注出弁４０は、中栓部１０の流通孔１１ｅを通じた注出孔２６と内容器５内との連通、遮断を切替える。本実施形態において注出弁４０は、後述する筒体部５１の内周面から径方向の内側に突出している。注出弁４０は、収容筒部７０を囲む円環板状である。注出弁４０は、上下方向に弾性変形可能な弾性体である。注出弁４０の径方向内周縁部は、径方向内側に向かうに従って下方に向けて湾曲する湾曲部４１となっている。湾曲部４１は、収容筒部本体７１の径方向外周縁部７１ｂの上端面に、上方に離反可能に配置されている。 The discharge valve 40 closes the flow hole 11e so as to be openable. As a result, the dispensing valve 40 switches between communication and blocking between the dispensing hole 26 and the inside of the inner container 5 through the distribution hole 11e of the inner plug portion 10. In the present embodiment, the discharge valve 40 protrudes inward in the radial direction from the inner peripheral surface of the tubular body portion 51, which will be described later. The discharge valve 40 has an annular plate shape that surrounds the accommodating cylinder portion 70. The discharge valve 40 is an elastic body that can be elastically deformed in the vertical direction. The radial inner peripheral edge portion of the injection valve 40 is a curved portion 41 that curves downward toward the inside in the radial direction. The curved portion 41 is arranged on the upper end surface of the radial outer peripheral edge portion 71b of the accommodating cylinder portion main body 71 so as to be detachable upward.

本実施形態において注出弁４０は、収容筒部７０と立ち上がり筒部１４および筒体部５１との径方向の間、すなわち環状空洞部７３を上方から覆って開放可能に閉塞している。これにより、本実施形態において注出弁４０は、環状空洞部７３を容器本体４側と逆側から開放可能に閉塞することによって、内ベース部１１ｂのうち収容筒部７０と立ち上がり筒部１４との径方向の間に位置する部分に形成された流通孔１１ｅを開放可能に閉塞している。本実施形態において注出弁４０は、湾曲部４１がキャップ本体２０の中心軸方向（上下方向）において容器本体４側と逆側（上側）に移動することで、環状空洞部７３を上方に開放し、流通孔１１ｅを開放する。 In the present embodiment, the discharge valve 40 is openly closed between the accommodating cylinder portion 70, the rising cylinder portion 14, and the cylinder portion 51 in the radial direction, that is, covering the annular cavity portion 73 from above. As a result, in the present embodiment, the discharge valve 40 closes the annular cavity portion 73 so as to be openable from the side opposite to the container body 4 side, so that the inner base portion 11b becomes the accommodating cylinder portion 70 and the rising cylinder portion 14. The flow hole 11e formed in the portion located between the radial directions of the above is operably closed. In the present embodiment, the pouring valve 40 opens the annular cavity portion 73 upward by moving the curved portion 41 to the opposite side (upper side) of the container body 4 side in the central axis direction (vertical direction) of the cap body 20. Then, the distribution hole 11e is opened.

注出弁４０は、外容器６のスクイズ変形に伴い内容器５の内圧が上昇した際に弾性変形し、湾曲部４１が収容筒部７０の径方向外周縁部７１ｂの上端面から上方に離反する。これにより、外容器６のスクイズ変形時に、流通孔１１ｅを開放させて、注出孔２６と内容器５内とを連通させるとともに、内容物を注出孔２６から注出させることが可能とされている。
なお、注出弁４０としては、外容器６のスクイズ変形時に流通孔１１ｅを開放できればよく、上記構成以外の弁構造を採用してもよい。 The discharge valve 40 elastically deforms when the internal pressure of the inner container 5 rises due to the squeeze deformation of the outer container 6, and the curved portion 41 separates upward from the upper end surface of the radial outer peripheral edge portion 71b of the accommodating cylinder portion 70. do. As a result, when the outer container 6 is deformed by squeeze, the flow hole 11e can be opened so that the pouring hole 26 and the inside of the inner container 5 communicate with each other, and the contents can be poured out from the pouring hole 26. ing.
As the pouring valve 40, it is sufficient that the flow hole 11e can be opened when the outer container 6 is deformed by squeeze, and a valve structure other than the above configuration may be adopted.

空気弁５０は、下端部が中栓部１０の連結筒部１１ｃ内に嵌合され、上端部がキャップ本体２０の垂下筒２４内に嵌合された筒体部５１と、筒体部５１の外周面から径方向の外側に向けて突出し、径方向の外端部が自由端とされた弾性変形可能な環状の弁体５２と、を有している。筒体部５１の下端部は、例えば、連結筒部１１ｃと立ち上がり筒部１４との径方向の間に嵌合されている。 The air valve 50 has a tubular body 51 whose lower end is fitted in the connecting tubular portion 11c of the inner plug portion 10 and whose upper end is fitted in the hanging cylinder 24 of the cap body 20, and the tubular portion 51. It has an annular valve body 52 that is elastically deformable and protrudes outward from the outer peripheral surface in the radial direction and has an outer end portion in the radial direction as a free end. The lower end portion of the tubular body portion 51 is fitted, for example, between the connecting tubular portion 11c and the rising tubular portion 14 in the radial direction.

弁体５２は、径方向の外端部が周方向の全周にわたってキャップ本体２０の天壁部２２の下面に離反可能に接触しており、外気導入孔２３を下方から開放可能に閉塞している。弁体５２は、外気導入孔２３を通じたキャップ本体２０の外部からキャップ本体２０の内部への空気の流入を許容し、かつ外気導入孔２３を通じたキャップ本体２０の内部からキャップ本体２０の外部への空気の流出を規制する逆止弁として機能する。外気導入孔２３を通じてキャップ本体２０の外部からキャップ本体２０の内部に流入した空気は、中栓部１０の連絡孔１１ｄ、キャップ本体２０の連通溝２１ａ、および外容器６の吸気孔８を通じて、内容器５と外容器６との間に流入する。
なお、本実施形態において注出弁４０と空気弁５０とは一体に形成された構成としたが、注出弁４０と空気弁５０とを互いに別部材としてもよい。 In the valve body 52, the outer end portion in the radial direction is in contact with the lower surface of the top wall portion 22 of the cap body 20 so as to be detachable over the entire circumference in the circumferential direction, and the outside air introduction hole 23 is closed so as to be openable from below. There is. The valve body 52 allows air to flow from the outside of the cap body 20 through the outside air introduction hole 23 into the inside of the cap body 20, and also allows air to flow from the inside of the cap body 20 through the outside air introduction hole 23 to the outside of the cap body 20. Functions as a check valve that regulates the outflow of air. The air that has flowed into the inside of the cap body 20 from the outside of the cap body 20 through the outside air introduction hole 23 passes through the communication hole 11d of the inner plug portion 10, the communication groove 21a of the cap body 20, and the intake hole 8 of the outer container 6. It flows between the vessel 5 and the outer container 6.
In addition, although the pouring valve 40 and the air valve 50 are integrally formed in the present embodiment, the pouring valve 40 and the air valve 50 may be used as separate members from each other.

以上の構成において、内容物を注出するには、まず、指かけ部３５を引き上げて、若しくは押し上げて蓋体３０をヒンジ部３４回りに上方に回動させ、注出孔２６を開放させた後に、例えば注出容器１を傾倒または上下反転させながら、外容器６をスクイズ変形（弾性変形）させる。これにより、内容器５が外容器６とともに変形して減容するので、内容器５の内圧が上昇する。このとき、収容筒部７０内の摺動体８０は、図４に示すように、弁座部７０ａから離れる向きに移動する。すると、開放された開口部７０ｂから、内容器５の内部に収容された内容物が収容筒部７０内に流入する。収容筒部７０内に流入した内容物は、収容筒部７０における係止片７２同士の周方向の隙間、または収容筒部７０の上側の開口部を通じて注出孔２６へと流れる。これにより、収容筒部７０内を介して、注出孔２６から内容物を注出することができる。なお、図４では、注出容器１を上下反転させた状態を示している。 In the above configuration, in order to dispense the contents, first, the finger hook portion 35 is pulled up or pushed up to rotate the lid 30 upward around the hinge portion 34, and the pouring hole 26 is opened. Later, for example, the outer container 6 is squeezed (elastically deformed) while the pouring container 1 is tilted or turned upside down. As a result, the inner container 5 is deformed together with the outer container 6 to reduce the volume, so that the internal pressure of the inner container 5 rises. At this time, as shown in FIG. 4, the sliding body 80 in the accommodating cylinder portion 70 moves in a direction away from the valve seat portion 70a. Then, the contents contained in the inner container 5 flow into the accommodating cylinder portion 70 from the opened opening 70b. The contents flowing into the accommodating cylinder 70 flow into the pouring hole 26 through the circumferential gap between the locking pieces 72 in the accommodating cylinder 70 or the opening on the upper side of the accommodating cylinder 70. As a result, the contents can be poured out from the pouring hole 26 via the inside of the accommodating cylinder portion 70. Note that FIG. 4 shows a state in which the pouring container 1 is turned upside down.

また、外容器６をある程度強く押圧して大きくスクイズ変形させた場合等、内容器５の内圧が比較的大きく上昇した場合には、注出弁４０が弾性変形し、湾曲部４１が収容筒部７０における径方向外周縁部７１ｂの上端面から離反するので、流通孔１１ｅが開放されて注出孔２６と内容器５の内部とが流通孔１１ｅを通じて連通する。これにより、内容器５の内部に収容された内容物を、流通孔１１ｅを介して、注出孔２６から外部に注出することもできる。したがって、収容筒部７０内を単位時間当たりに流通可能な内容物の量よりも多量の内容物を単位時間当たりに注出することができる。本実施形態では、流通孔１１ｅは内ベース部１１ｂのうち収容筒部７０と立ち上がり筒部１４との径方向の間に位置する部分に設けられているため、内容物は、流通孔１１ｅから収容筒部７０と立ち上がり筒部１４との径方向の間に設けられた環状空洞部７３を通じて注出される。 Further, when the internal pressure of the inner container 5 rises relatively greatly, such as when the outer container 6 is strongly pressed to some extent to cause a large squeeze deformation, the pouring valve 40 is elastically deformed and the curved portion 41 is a storage cylinder portion. Since the 70 is separated from the upper end surface of the radial outer peripheral edge portion 71b, the flow hole 11e is opened and the injection hole 26 and the inside of the inner container 5 communicate with each other through the flow hole 11e. As a result, the contents contained in the inner container 5 can be poured out from the pouring hole 26 through the distribution hole 11e. Therefore, it is possible to pour out a larger amount of contents per unit time than the amount of contents that can be distributed in the storage cylinder 70 per unit time. In the present embodiment, since the flow hole 11e is provided in the inner base portion 11b located between the accommodating cylinder portion 70 and the rising cylinder portion 14 in the radial direction, the contents are accommodated from the flow hole 11e. It is poured out through an annular cavity portion 73 provided between the tubular portion 70 and the rising tubular portion 14 in the radial direction.

容器本体４のスクイズ変形を停止または解除することで、内容器５の内圧の上昇が停止または低下すると、内容物の注出が停止される。また、上述したように注出時において注出弁４０が流通孔１１ｅを開放した状態となっていた場合には、注出弁４０が復元変形し、湾曲部４１が収容筒部７０における径方向外周縁部７１ｂの上端面に着座する。これにより、流通孔１１ｅが再び閉塞される。 By stopping or releasing the squeeze deformation of the container body 4, when the increase in the internal pressure of the inner container 5 is stopped or decreased, the pouring of the contents is stopped. Further, as described above, when the dispensing valve 40 is in a state where the flow hole 11e is opened at the time of dispensing, the dispensing valve 40 is restored and deformed, and the curved portion 41 is radially in the accommodating cylinder portion 70. It sits on the upper end surface of the outer peripheral edge portion 71b. As a result, the flow hole 11e is closed again.

また、容器本体４のスクイズ変形を解除することで、外容器６が復元変形し始めるので、外容器６と内容器５との間に負圧が生じる。すると、この負圧が吸気孔８、連通溝２１ａ、および連絡孔１１ｄを通じて空気弁５０に作用するので、弁体５２における径方向の外端部が、天壁部２２の下面から下方に向けて離間し、外気導入孔２３を開放する。これにより、外気導入孔２３を通じてキャップ本体２０の外部から空気が流入し、この空気が、連絡孔１１ｄ、連通溝２１ａおよび吸気孔８を通じて内容器５と外容器６との間に流入する。
その結果、外容器６が復元変形したとしても、内容器５を外容器６の内面から離間させて減容変形させたままの状態にしておくことができる。 Further, by releasing the squeeze deformation of the container body 4, the outer container 6 begins to be restored and deformed, so that a negative pressure is generated between the outer container 6 and the inner container 5. Then, since this negative pressure acts on the air valve 50 through the intake hole 8, the communication groove 21a, and the communication hole 11d, the radial outer end portion of the valve body 52 is directed downward from the lower surface of the top wall portion 22. Separated and open the outside air introduction hole 23. As a result, air flows in from the outside of the cap body 20 through the outside air introduction hole 23, and this air flows in between the inner container 5 and the outer container 6 through the communication hole 11d, the communication groove 21a, and the intake hole 8.
As a result, even if the outer container 6 is restored and deformed, the inner container 5 can be separated from the inner surface of the outer container 6 and kept in a state of being reduced in volume and deformed.

また、容器本体４のスクイズ変形の解除にあわせて容器本体４を正立姿勢に戻すことで、収容筒部７０内の摺動体８０を、自重により弁座部７０ａに近付く向きに移動させて、弁座部７０ａに着座させる。これにより、摺動体８０の移動に伴うサックバック効果によって、ベース部１１の上方に内容物が残留したとしても、その残留した内容物を収容筒部７０内に引き込むことができる。したがって、残留内容物が注出筒１９を通じて外部に漏れ難く、液だれを抑制することができる。
なお、内容器５の内圧上昇を利用して、収容筒部７０内の摺動体８０を、弁座部７０ａから離れる向きに移動させることも可能であるので、内容物の注出時に必ずしも注出容器１を傾倒または上下反転させる必要はない。 Further, by returning the container body 4 to the upright posture in accordance with the release of the squeeze deformation of the container body 4, the sliding body 80 in the accommodating cylinder 70 is moved in a direction approaching the valve seat 70a by its own weight. It is seated on the valve seat portion 70a. As a result, even if the contents remain above the base portion 11 due to the suckback effect accompanying the movement of the sliding body 80, the remaining contents can be drawn into the accommodating cylinder portion 70. Therefore, the residual contents are less likely to leak to the outside through the pouring cylinder 19, and dripping can be suppressed.
Since it is possible to move the sliding body 80 in the accommodating cylinder portion 70 in a direction away from the valve seat portion 70a by utilizing the increase in the internal pressure of the inner container 5, it is not always necessary to dispense the contents when pouring out the contents. It is not necessary to tilt or turn the container 1 upside down.

また、注出容器１を上下反転させた際の内容物の液面が、図４に示す仮想線ＩＬの位置以下になると、収容筒部７０の開口部７０ｂが内容物から露出する。すなわち、開口部７０ｂが、容器本体４内の空気に露出する。仮想線ＩＬは、上下方向と直交し、収容筒部７０の開口部７０ｂと同じ上下方向位置を通る仮想線である。 Further, when the liquid level of the contents when the pouring container 1 is turned upside down becomes equal to or lower than the position of the virtual line IL shown in FIG. 4, the opening 70b of the accommodating cylinder 70 is exposed from the contents. That is, the opening 70b is exposed to the air inside the container body 4. The virtual line IL is a virtual line that is orthogonal to the vertical direction and passes through the same vertical position as the opening 70b of the accommodating cylinder 70.

この場合、容器本体４をスクイズ変形させた際に、容器本体４内の空気が収容筒部７０の開口部７０ｂから注出孔２６へと抜け出るため、容器本体４内の圧力が上昇しにくくなる。そのため、上述したように外容器６をある程度強く押圧する等により容器本体４を比較的大きくスクイズ変形させても、注出弁４０を開放できず、内容物を注出孔２６から注出できなくなる場合がある。したがって、注出容器１を上下反転させた際に、液面が仮想線ＩＬの位置となる量の内容物が残留したまま、内容物を外部に注出できなくなる場合があった。 In this case, when the container body 4 is squeeze-deformed, the air inside the container body 4 escapes from the opening 70b of the storage cylinder 70 to the pouring hole 26, so that the pressure inside the container body 4 is less likely to increase. .. Therefore, as described above, even if the container body 4 is squeeze-deformed relatively large by pressing the outer container 6 to some extent, the dispensing valve 40 cannot be opened and the contents cannot be dispensed from the dispensing hole 26. In some cases. Therefore, when the pouring container 1 is turned upside down, the contents may not be able to be pouring out while the amount of the contents remaining at the position of the virtual line IL on the liquid level remains.

そのため、容器本体４内に残留する内容物の量を少なくするためには、収容筒部７０の開口部７０ｂの上下方向位置をできる限り容器本体４側とは逆側、すなわち図１における上側に配置することが好ましい。言い換えれば、図４のように注出容器１を倒立させた際に、仮想線ＩＬの位置をできる限り下げることが好ましい。しかし、この場合、収容筒部７０の上下方向の寸法が短くなりやすく、収容筒部７０内における摺動体８０の上下方向のストローク量が小さくなりやすい。そのため、サックバック機能が低下する虞があった。 Therefore, in order to reduce the amount of the contents remaining in the container body 4, the vertical position of the opening 70b of the storage cylinder 70 is located on the opposite side to the container body 4 side as much as possible, that is, on the upper side in FIG. It is preferable to arrange it. In other words, it is preferable to lower the position of the virtual line IL as much as possible when the pouring container 1 is inverted as shown in FIG. However, in this case, the vertical dimension of the accommodating cylinder 70 tends to be short, and the vertical stroke amount of the sliding body 80 in the accommodating cylinder 70 tends to be small. Therefore, there is a risk that the suckback function will deteriorate.

これに対して本実施形態によれば、収容筒部７０は、収容筒部本体７１の周方向に沿って互いに隙間を空けて形成された複数の係止片７２を有し、複数の係止片７２は、中栓部１０のうち流通孔１１ｅが形成された部分よりも容器本体４側と逆側（上側）に位置する。そのため、複数の係止片７２によって、収容筒部７０全体の上下方向の寸法を維持しつつ、ベース部１１から容器本体４側に突出する収容筒部７０の突出長さを小さくできる。これにより、収容筒部７０全体がベース部１１から容器本体４側に突出している場合に比べて、収容筒部７０の開口部７０ｂの位置を容器本体４側と逆側（上側）に配置することができる。すなわち、注出容器１を倒立させた際に、仮想線ＩＬの位置をより下げることができる。したがって、容器本体４内の内容物の量が比較的少なくなっても、注出容器１を倒立させた際に開口部７０ｂが空気に露出しにくくできる。そのため、本実施形態によれば、収容筒部７０内における摺動体８０のストローク量を確保してサックバック機能を好適に維持しつつ、容器本体４内に残留する内容物の量を低減できる。 On the other hand, according to the present embodiment, the accommodating cylinder portion 70 has a plurality of locking pieces 72 formed with a gap from each other along the circumferential direction of the accommodating cylinder portion main body 71, and a plurality of locking pieces 72 are provided. The piece 72 is located on the opposite side (upper side) of the container main body 4 side from the portion of the inner plug portion 10 in which the flow hole 11e is formed. Therefore, the plurality of locking pieces 72 can reduce the protruding length of the storage cylinder portion 70 protruding from the base portion 11 to the container main body 4 side while maintaining the vertical dimension of the entire storage cylinder portion 70. As a result, the position of the opening 70b of the storage cylinder 70 is arranged on the opposite side (upper side) of the container body 4 side as compared with the case where the entire storage cylinder 70 protrudes from the base 11 toward the container body 4. be able to. That is, when the pouring container 1 is inverted, the position of the virtual line IL can be further lowered. Therefore, even if the amount of the contents in the container body 4 is relatively small, the opening 70b can be less likely to be exposed to the air when the pouring container 1 is inverted. Therefore, according to the present embodiment, it is possible to reduce the amount of contents remaining in the container main body 4 while securing the stroke amount of the sliding body 80 in the accommodating cylinder portion 70 and maintaining the suckback function appropriately.

また、本実施形態によれば、収容筒部７０の内部と注出孔２６とは、係止片７２同士の周方向の隙間を通じて連通している。そのため、収容筒部７０内に流入した内容物を、係止片７２同士の周方向の隙間を介して、注出孔２６へと好適に流すことができる。したがって、本実施形態によれば、容器本体４内に残留する内容物の量を低減でき、かつ、収容筒部７０内を介した内容物の注出を円滑に行うことができる。係止片７２同士の周方向の隙間の大きさを調整することにより、収容筒部７０内から係止片７２同士の周方向の隙間を通じて注出される内容物の量を調整可能である。 Further, according to the present embodiment, the inside of the accommodating cylinder portion 70 and the ejection hole 26 communicate with each other through a gap in the circumferential direction between the locking pieces 72. Therefore, the contents that have flowed into the accommodating cylinder portion 70 can be suitably flowed to the pouring hole 26 through the gap in the circumferential direction between the locking pieces 72. Therefore, according to the present embodiment, the amount of the contents remaining in the container main body 4 can be reduced, and the contents can be smoothly poured out through the storage cylinder portion 70. By adjusting the size of the circumferential gap between the locking pieces 72, it is possible to adjust the amount of the contents discharged from the accommodation cylinder 70 through the circumferential gap between the locking pieces 72.

また、本実施形態によれば、係止片７２の上下方向の寸法は、摺動体８０の半径よりも大きい。そのため、例えば図１に二点鎖線で示すように、摺動体８０の中心が係止片７２の下端部よりも上方に位置した状態で、摺動体８０を収容筒部７０内に収容可能となる。これにより、収容筒部本体７１の内部のうち摺動体８０よりも下方に位置する部分と係止片７２同士の周方向の隙間とを直接的に連通させることができる。したがって、摺動体８０の中心が係止片７２の下端部よりも上方に位置することで、開口部７０ｂから収容筒部７０内に流入した内容物を、摺動体８０と収容筒部７０の内周面との僅かな隙間を介さずに、係止片７２同士の周方向の隙間に流すことができる。そのため、収容筒部７０内に流入した内容物を、係止片７２同士の周方向の隙間を介して、注出孔２６へとより好適に流すことができる。したがって、本実施形態によれば、収容筒部７０内を介した内容物の注出をより円滑に行うことができる。 Further, according to the present embodiment, the vertical dimension of the locking piece 72 is larger than the radius of the sliding body 80. Therefore, for example, as shown by the alternate long and short dash line in FIG. 1, the sliding body 80 can be accommodated in the accommodating cylinder portion 70 in a state where the center of the sliding body 80 is located above the lower end portion of the locking piece 72. .. As a result, the portion of the inside of the accommodating cylinder portion 71 located below the sliding body 80 and the gap between the locking pieces 72 in the circumferential direction can be directly communicated with each other. Therefore, since the center of the sliding body 80 is located above the lower end portion of the locking piece 72, the contents that have flowed into the accommodating cylinder portion 70 from the opening 70b can be taken into the sliding body 80 and the accommodating cylinder portion 70. It is possible to flow through the gap in the circumferential direction between the locking pieces 72 without passing through a slight gap with the peripheral surface. Therefore, the contents that have flowed into the accommodating cylinder portion 70 can be more preferably flowed to the pouring hole 26 through the gap in the circumferential direction between the locking pieces 72. Therefore, according to the present embodiment, the contents can be more smoothly poured out through the inside of the accommodating cylinder portion 70.

また、本実施形態によれば、収容筒部本体７１のうちベース部１１から容器本体４側（下側）に突出する部分の上下方向の寸法は、摺動体８０の直径以下である。そのため、収容筒部７０の開口部７０ｂの位置を好適に上側にしやすく、注出容器１を倒立させた際の仮想線ＩＬの位置を好適に下げることができる。したがって、容器本体４内に残留する内容物の量を好適に低減しやすい。
なお、摺動体８０が収容筒部７０内を上下方向に移動することでサックバック効果により液だれを回避することが可能であるならば、収容筒部７０の上下方向の長さを図１に示す収容筒部７０より短くしてもよい。この場合、開口部７０ｂの位置をより上側に配置できるため、容器本体４内に残留する内容物の量をより低減できる。 Further, according to the present embodiment, the vertical dimension of the portion of the accommodating cylinder portion main body 71 that protrudes from the base portion 11 to the container main body 4 side (lower side) is not more than the diameter of the sliding body 80. Therefore, the position of the opening 70b of the storage cylinder 70 can be easily moved upward, and the position of the virtual line IL when the pouring container 1 is inverted can be preferably lowered. Therefore, it is easy to suitably reduce the amount of the contents remaining in the container body 4.
If it is possible to avoid dripping by the suckback effect by moving the sliding body 80 in the vertical direction in the housing cylinder 70, the length of the housing cylinder 70 in the vertical direction is shown in FIG. It may be shorter than the storage cylinder portion 70 shown. In this case, since the position of the opening 70b can be arranged on the upper side, the amount of the contents remaining in the container body 4 can be further reduced.

また、本実施形態によれば、収容筒部７０のうちベース部１１から容器本体４側と逆側に延びる部分の周囲には、収容筒部７０を囲む環状であり、流通孔１１ｅに連通する環状空洞部７３が形成されている。また、注出弁４０は、環状空洞部７３を容器本体４側と逆側から開放可能に閉塞することによって、流通孔１１ｅを開放可能に閉塞している。そのため、容器本体４をスクイズ変形させた際、注出弁４０は、環状空洞部７３内の内容物または空気を介して開放される向きに力を受ける。これにより、例えば注出弁４０によって流通孔１１ｅを直接的に閉塞する場合に比べて、注出弁４０の受圧面積を大きくしやすい。したがって、容器本体４内の空気が収容筒部７０の開口部７０ｂから注出孔２６へと抜け出る場合であっても、外容器６をある程度強く押圧する等により容器本体４を比較的大きくスクイズ変形させることで、注出弁４０を開放しやすくできる。そのため、注出容器１を上下反転させた際に液面が仮想線ＩＬの位置以下となった場合、すなわち注出容器１を倒立させた際に収容筒部７０の開口部７０ｂが空気に露出した場合であっても、注出弁４０を開放させて、流通孔１１ｅを通じて内容物を注出しやすくできる。これにより、容器本体４内に残留する内容物の量をより低減できる。 Further, according to the present embodiment, around the portion of the storage cylinder portion 70 extending from the base portion 11 to the side opposite to the container body 4 side, an annular shape surrounding the storage cylinder portion 70 is formed and communicates with the distribution hole 11e. An annular cavity 73 is formed. Further, the discharge valve 40 closes the flow hole 11e so as to be openable by closing the annular cavity portion 73 so as to be openable from the side opposite to the container body 4 side. Therefore, when the container body 4 is squeeze-deformed, the discharge valve 40 receives a force in a direction of being opened through the contents or air in the annular cavity portion 73. As a result, it is easy to increase the pressure receiving area of the dispensing valve 40 as compared with the case where the distribution hole 11e is directly closed by, for example, the dispensing valve 40. Therefore, even when the air in the container body 4 escapes from the opening 70b of the storage cylinder 70 to the pouring hole 26, the container body 4 is squeeze-deformed relatively greatly by pressing the outer container 6 with some force or the like. By making it possible, the dispenser valve 40 can be easily opened. Therefore, when the liquid level is below the position of the virtual line IL when the pouring container 1 is turned upside down, that is, when the pouring container 1 is inverted, the opening 70b of the accommodating cylinder 70 is exposed to air. Even in this case, the dispensing valve 40 can be opened to facilitate the dispensing of the contents through the distribution hole 11e. As a result, the amount of the contents remaining in the container body 4 can be further reduced.

また、本実施形態によれば、中栓部１０は、収容筒部７０から径方向の外側に広がり容器本体４の内部に面する平坦面１１ｆを有し、流通孔１１ｅは、平坦面１１ｆに開口している。そのため、流通孔１１ｅ内に内容物を流入させやすくでき、流通孔１１ｅを通じて内容物を注出させやすくできる。これにより、容器本体４内に残留する内容物の量をより低減できる。 Further, according to the present embodiment, the inner plug portion 10 has a flat surface 11f that extends radially outward from the accommodating cylinder portion 70 and faces the inside of the container body 4, and the flow hole 11e is formed on the flat surface 11f. It is open. Therefore, the contents can be easily flowed into the distribution hole 11e, and the contents can be easily poured out through the distribution hole 11e. As a result, the amount of the contents remaining in the container body 4 can be further reduced.

また、本実施形態によれば、開口部７０ｂの内径は、収容筒部７０のうち内側に摺動体８０を収容可能な部分の内径の１／４以上である。そのため、開口部７０ｂの内径を比較的大きくできる。これにより、容器本体４内の内容物が開口部７０ｂから収容筒部７０内に入りやすくなり、収容筒部７０内を介して内容物を注出しやすくできる。したがって、容器本体４をスクイズ変形させる際に、容器本体４を押圧する力を小さくできる。そのため、容器本体４をスクイズ変形させやすくでき、使用者の利便性を向上できる。 Further, according to the present embodiment, the inner diameter of the opening 70b is 1/4 or more of the inner diameter of the portion of the accommodating cylinder portion 70 that can accommodate the sliding body 80 inside. Therefore, the inner diameter of the opening 70b can be made relatively large. As a result, the contents in the container main body 4 can easily enter the storage cylinder 70 through the opening 70b, and the contents can be easily poured out through the storage cylinder 70. Therefore, when the container body 4 is squeeze-deformed, the force for pressing the container body 4 can be reduced. Therefore, the container body 4 can be easily deformed by squeeze, and the convenience of the user can be improved.
