Description

本発明は、注出キャップ及びそれを備えた液体注出具に関する。 TECHNICAL FIELD The present invention relates to a dispensing cap and a liquid dispensing device including the same.

従来、各種洗剤や化粧品、食品等が収容された小型の液体注出具には、各種洗剤や化粧品、食品等が予め収容された容器に注出キャップが直接取り付けられており、注出キャップを介して容器内に収容された液状内容物が注出される。 Conventionally, for small liquid spouts containing various detergents, cosmetics, foods, etc., a spout cap is directly attached to a container in which various detergents, cosmetics, foods, etc. are stored in advance. The liquid contents contained in the container are poured out.

そのため、注出キャップには、液状内容物の不定期な変動を伴った流出を防止するための様々な工夫がなされている。例えば特許文献１には、複数の流出孔を等間隔に設けることで、液状内容物を注出する際の空気置換を容易に行えるようにした注出中栓が開示されている。また特許文献２には、突出筒部の天面部の内面に内容物を衝突させて、内容物の勢いを低減させる中栓部材が開示されている。 Therefore, the spout cap has been devised in various ways to prevent the liquid content from flowing out with irregular fluctuations. For example, Patent Document 1 discloses a pouring plug that facilitates air replacement when pouring a liquid content by providing a plurality of outflow holes at equal intervals. Further, Patent Document 2 discloses an inner plug member that reduces the momentum of the content by colliding the content with the inner surface of the top surface portion of the protruding tubular portion.

特開平１０−１７５６５８号公報JP, 10-175658, A 特開２０１０−６３９６号公報JP, 2010-6396, A

一方、容器内に収容される液状内容物には様々な成分が含有しているのが一般的であるが、液状内容物の粘度によって、液状内容物を出しにくかったり、また一度に大量の液状内容物がでてしまう場合がある。このように、容器内に収容された液状内容物においては、一定量を安定して注出するのに苦労を要することがある。 On the other hand, it is general that the liquid content contained in the container contains various components. However, depending on the viscosity of the liquid content, it may be difficult to take out the liquid content or a large amount of liquid content at a time. The contents may come out. As described above, it may be difficult to stably pour out a certain amount of the liquid content contained in the container.

これに対しては、例えば、上記の特許文献１に記載の注出中栓では、空気置換を行うことで注出時における液状内容物の不定期な変動を伴った流出は防止できるが、一定量を安定して注出させることは容易ではない。また、特許文献２に記載の中栓部材においては、突出筒部を設けることで注出時の液状内容物の勢いを低減させることはできるが、突出筒部が注出口部よりもキャップ軸よりに設けられているため、突出筒部に設けられた開口から流出される液状内容物はすぐに注出口部に到達し、注出されることとなる。つまり、特許文献２に記載の中栓部材においても、一定量の液状内容物を安定して注出させることは容易ではない。 On the other hand, for example, in the pouring stopper described in Patent Document 1 described above, by performing air replacement, the liquid content can be prevented from flowing out with irregular fluctuations at the time of pouring, but it is constant. It is not easy to dispense a stable amount. Further, in the inner plug member described in Patent Document 2, by providing the projecting tubular portion, the momentum of the liquid content at the time of pouring can be reduced, but the projecting tubular portion is located closer to the cap shaft than the spout portion. Therefore, the liquid content flowing out from the opening provided in the protruding cylindrical portion immediately reaches the spout portion and is spouted. That is, even with the inner plug member described in Patent Document 2, it is not easy to stably pour out a certain amount of liquid content.

したがって本発明の課題は、前述した従来技術が有する欠点を解消し得る注出キャップ及び液体注出具を提供することにある。 Therefore, an object of the present invention is to provide a pouring cap and a liquid pouring tool which can solve the above-mentioned drawbacks of the prior art.

本発明は、容器の口部に取り付けられて使用される注出キャップであって、有底筒状の注出口部と、該注出口部の底部から突出し、該注出口部の筒状部との間に環状の溝部を形成する突出部と、前記突出部の外周部又は平面視において該外周部より外側に設けられ、前記容器内の液状内容物を前記溝部内に流出させる複数の流出孔とを備えており、前記突出部の中心軸から該突出部の前記外周部までの距離ｄ１と、該中心軸から前記筒状部の内周面までの距離ｄ２とが、関係式ｄ１＞ｄ２／２を満たす注出キャップを提供するものである。 The present invention is a spout cap that is used by being attached to the mouth of a container, and has a bottomed cylindrical spout, and a cylindrical part of the spout that projects from the bottom of the spout. And a plurality of outflow holes provided in the outer peripheral portion of the protruding portion forming an annular groove portion between the outer peripheral portion or the outer peripheral portion in plan view, for letting out the liquid content in the container into the groove portion. And a distance d1 from the central axis of the projecting portion to the outer peripheral portion of the projecting portion and a distance d2 from the central axis to the inner peripheral surface of the tubular portion are expressed by a relational expression d1>d2. The purpose of the present invention is to provide a pouring cap satisfying /2.

以下本発明を、その好ましい実施形態に基づき図面を参照しながら説明する。図１には、本発明の実施形態に係る注出キャップ１を有する液体注出具１００の斜視図が示されており、図２には図１に示す注出キャップ１のＡ−Ａ線断面図が示されている。図３には、図１に示す注出キャップ１を上方から見た略示平面図（上面図）が示されており、図４には、図１に示す注出キャップ１の略示底面図が示されている。 The present invention will be described below based on its preferred embodiments with reference to the drawings. FIG. 1 is a perspective view of a liquid pouring tool 100 having a pouring cap 1 according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA of the pouring cap 1 shown in FIG. It is shown. FIG. 3 shows a schematic plan view (top view) of the pouring cap 1 shown in FIG. 1 seen from above, and FIG. 4 shows a schematic bottom view of the pouring cap 1 shown in FIG. It is shown.

本発明の実施形態に係る液体注出具１００は、液状内容物として化粧水が収容されている化粧水注出具であり、図１に示すように、化粧水を注出する際に用いられる注出キャップ１と、化粧水が収容された容器２とを備えている。 A liquid pouring tool 100 according to an embodiment of the present invention is a lotion pouring tool in which a lotion is contained as a liquid content, and as shown in FIG. 1, a pouring liquid used when pouring a lotion. It is provided with a cap 1 and a container 2 containing a lotion.

図２〜図４に示すように、注出キャップ１は、有底筒状の注出口部１０と、該注出口部１０の底部１６から突出し、該注出口部１０の筒状部１５との間に環状の溝部１９を形成する突出部１１と、突出部１１の外周部１８に設けられ、容器２内の化粧水を溝部１９内に流出させる複数の流出孔１２ａ〜１２ｄとを備えている。また注出キャップ１は、注出口部１０の下部に設けられ、容器２に取り付けられる取付け部１３と、取付け部１３の内部に設けられ、容器２をシールするシール部１４とを備えている。 As shown in FIGS. 2 to 4, the spout cap 1 includes a bottomed tubular spout portion 10 and a tubular portion 15 of the spout portion 10 that protrudes from a bottom portion 16 of the spout portion 10. It is provided with a projecting portion 11 that forms an annular groove portion 19 therebetween, and a plurality of outflow holes 12a to 12d that are provided on the outer peripheral portion 18 of the projecting portion 11 and that allow the lotion in the container 2 to flow into the groove portion 19. .. Further, the spout cap 1 includes a mounting portion 13 that is provided below the spout portion 10 and that is mounted on the container 2, and a seal portion 14 that is provided inside the mounting portion 13 and seals the container 2.

注出口部１０は、円筒状に形成された筒状部１５と、筒状部１５の内部に設けられる底部１６とを有している。
図２及び図３に示すように、筒状部１５は、平面視における、注出キャップ１の中心軸（以下、単に「中心軸」ともいう）Ｘからの距離（半径）が、根本部から先端部に向けて徐々に大きくなる広がり形状に形成されている。また、筒状部１５は、根本部から先端部に向かって肉厚が徐々に薄くなるように形成されている。本実施形態では、筒状部１５の先端部側において、内周面１５ａの曲率を外周面１５ｂの曲率よりも大きくすることで、筒状部１５を先端部に向けて広がり形状にすると共に、先端部側の肉厚を徐々に薄くしている。
筒状部１５を根本部から先端部に向けて、外方に向かって曲面状に広がる広がり形状に形成することで、化粧水を注出し終えた際に、筒状部１５の先端での化粧水の流れの切れを好適にすることができる。また、先端部に向かって肉厚が薄くなるようにすることで、先端部側が弾性変形しやすくなり、後述するオーバーキャップ３で筒状部１５の先端部をシールし易くなる。 The spout 10 has a cylindrical portion 15 formed in a cylindrical shape and a bottom portion 16 provided inside the cylindrical portion 15.
As shown in FIGS. 2 and 3, the cylindrical portion 15 has a distance (radius) from the central axis (hereinafter, also simply referred to as “central axis”) X of the pouring cap 1 in plan view from the root portion. It is formed in a divergent shape that gradually increases toward the tip. Further, the tubular portion 15 is formed such that the wall thickness gradually decreases from the root portion toward the tip portion. In the present embodiment, by making the curvature of the inner peripheral surface 15a larger than the curvature of the outer peripheral surface 15b on the distal end side of the tubular portion 15, the tubular portion 15 has a widened shape toward the distal end, and The thickness of the tip side is gradually reduced.
By forming the tubular portion 15 from the root portion toward the tip portion to a spread shape that spreads outward in a curved shape, the makeup at the tip of the tubular portion 15 can be obtained after pouring the lotion. A break in the flow of water can be optimized. Further, by making the wall thickness thinner toward the tip portion, the tip portion side is easily elastically deformed, and the tip portion of the tubular portion 15 is easily sealed by the overcap 3 described later.

筒状部１５は、中心軸Ｘ方向の高さＨ１が、中心軸Ｘ方向における突出部１１の高さＨ２よりも高くなるように形成されることが好ましい。また筒状部１５は、中心軸Ｘ方向の高さＨ１が全周に亘って突出部１１の中心軸Ｘ方向の高さＨ２よりも高くなるよう形成されることが好ましい。筒状部１５の中心軸Ｘ方向の高さＨ１を突出部１１の中心軸Ｘ方向の高さＨ２よりも高くすることで、流出孔１２ａ〜１２ｄから流れ出した化粧水を視認しながらゆっくりと筒状部１５の先端まで移動させることができる。また複数の流出孔１２ａ〜１２ｄから化粧水が合流しやすくなる。 The cylindrical portion 15 is preferably formed so that the height H1 in the central axis X direction is higher than the height H2 of the protruding portion 11 in the central axis X direction. Further, it is preferable that the cylindrical portion 15 is formed such that the height H1 in the central axis X direction is higher than the height H2 in the central axis X direction of the projecting portion 11 over the entire circumference. By making the height H1 of the cylindrical portion 15 in the central axis X direction higher than the height H2 of the protruding portion 11 in the central axis X direction, while slowly observing the lotion flowing out from the outflow holes 12a to 12d, It can be moved to the tip of the portion 15. In addition, the lotion easily joins from the plurality of outflow holes 12a to 12d.

本実施形態では、筒状部１５は、中心軸Ｘ方向の高さＨ１が中心軸Ｘから突出部１１の外周部１８までの距離ｄ１（以下、単に「距離ｄ１」ともいう）よりも長くなるように形成されている。距離ｄ１は、中心軸Ｘと直交する方向における、中心軸Ｘから突出部１１の後述する外周部１８の外周面１８ａ側の基端までの距離である。また筒状部１５は、中心軸Ｘ方向の高さＨ１が全周に亘って距離ｄ１よりも長くなるように形成されている。更に筒状部１５は、全周に亘って同じ高さＨ１に形成されている。筒状部１５の中心軸Ｘ方向の高さＨ１を距離ｄ１よりも長くすることで、突出部１１の中心軸Ｘ方向の高さＨ２よりも高くした場合よりも、流出孔１２ａ〜１２ｄから流れ出した化粧水の視認が容易となり、上述した化粧水の流出状態の調整が容易となる。また複数の流出孔１２ａ〜１２ｄから化粧水が合流しやすくなる。更に、筒状部１５の中心軸Ｘ方向の高さＨ１を全周に亘って同じ高さにすることで、化粧水を注出する際の液体注出具１００の傾斜方向にかかわらず、筒状部１５の何れの箇所からも化粧水を同じように注出させることができる。 In the present embodiment, the cylindrical portion 15 has a height H1 in the central axis X direction longer than a distance d1 from the central axis X to the outer peripheral portion 18 of the protrusion 11 (hereinafter, also simply referred to as “distance d1”). Is formed. The distance d1 is the distance from the central axis X to the base end of the outer peripheral portion 18 of the protruding portion 11, which will be described later, on the outer peripheral surface 18a side in the direction orthogonal to the central axis X. Further, the tubular portion 15 is formed such that the height H1 in the central axis X direction is longer than the distance d1 over the entire circumference. Further, the tubular portion 15 is formed at the same height H1 over the entire circumference. By making the height H1 of the tubular portion 15 in the central axis X direction longer than the distance d1, it is possible to flow out from the outflow holes 12a to 12d more than when the height H2 of the protruding portion 11 in the central axis X direction is made higher. Further, it becomes easy to visually recognize the lotion, and it becomes easy to adjust the outflow state of the lotion described above. In addition, the lotion easily joins from the plurality of outflow holes 12a to 12d. Furthermore, by making the height H1 of the tubular portion 15 in the central axis X direction the same over the entire circumference, the tubular portion 15 is tubular regardless of the inclination direction of the liquid pouring tool 100 when pouring the lotion. The lotion can be similarly poured out from any part of the portion 15.

なお、本実施形態では、筒状部１５の中心軸Ｘ方向の高さＨ１を、周方向の全周に亘って、距離ｄ１よりも高くしたが、少なくとも一部を、距離ｄ１よりも高くしても良い。また本実施形態では、筒状部１５の中心軸Ｘ方向の高さＨ１を周方向の全周に亘って同じ高さにしたが、周方向における筒状部１５の中心軸Ｘ方向の高さＨ１を異なる高さにしても良い。また、筒状部１５は、根本部から先端部に向けて外方に向かって曲面状に広がる広がり形状に形成したが、根本部から先端部に向けて外方に向かって直線状に広がる広がり形状に形成しても良く、同径の筒状に形成しても良い。更に筒状部１５は、平面視において楕円形状や多角柱形状の筒状としても良い。 In the present embodiment, the height H1 of the tubular portion 15 in the central axis X direction is set higher than the distance d1 over the entire circumference in the circumferential direction, but at least a part of the height H1 is set higher than the distance d1. May be. Further, in the present embodiment, the height H1 of the tubular portion 15 in the central axis X direction is the same over the entire circumference in the circumferential direction, but the height of the tubular portion 15 in the circumferential direction in the central axis X direction is the same. H1 may have different heights. Further, although the tubular portion 15 is formed in a spread shape that spreads outward from the root portion toward the tip end portion in a curved shape, it spreads outwardly from the root portion toward the tip end portion in a straight line shape. It may be formed in a shape or a cylindrical shape having the same diameter. Furthermore, the tubular portion 15 may have an elliptical or polygonal columnar tubular shape in plan view.

底部１６は、注出口部１０の基端に設けられており、取付け部１３との間に配されている。また底部１６は、中心軸Ｘに対して略直交するように設けられている。 The bottom portion 16 is provided at the base end of the spout portion 10 and is arranged between the bottom portion 16 and the attachment portion 13. Further, the bottom portion 16 is provided so as to be substantially orthogonal to the central axis X.

図２に示すように、突出部１１は、底部１６に連結されており、底部１６の上面１６ａから中心軸Ｘ方向の上方に向けて突出形成されている。また突出部１１は、距離ｄ１と、中心軸Ｘから筒状部１５の内周面１５ａまでの距離ｄ２とが、関係式ｄ１＞ｄ２／２を満たしている。距離ｄ２は、中心軸Ｘと直交する方向における、中心軸Ｘから筒状部１５の内周面１５ａの基端までの距離（以下、単に「距離ｄ２」ともいう）である。突出部１１は、距離ｄ１と距離ｄ２とが関係式ｄ１＞ｄ２／２を満たすことで、注出口部１０の筒状部１５との間の好適な位置に、好適な幅の環状の溝部１９を形成することができる。具体的には、距離ｄ１と距離ｄ２とが関係式ｄ１＞ｄ２／２を満たすことで、溝部１９を筒状部１５に沿って好適に湾曲させた形状にすることが可能になり、例えば、化粧水を注出するために液体注出具１００を傾けた際に、化粧水が溝部１９に沿って注出位置に向けて湾曲して流れ、直線的に流れる場合よりも時間をかけて注出位置に到達させることができる。そのため、化粧水の注出状態が視認し易くなり、化粧水の注出を安定して容易に行うことができる。
また、使用者に化粧水が粘度を有しているように感じさせ、化粧水の効果に対する期待感を向上させることも期待できる。 As shown in FIG. 2, the protruding portion 11 is connected to the bottom portion 16 and is formed so as to protrude upward from the upper surface 16 a of the bottom portion 16 in the central axis X direction. In the protrusion 11, the distance d1 and the distance d2 from the central axis X to the inner peripheral surface 15a of the tubular portion 15 satisfy the relational expression d1>d2/2. The distance d2 is the distance from the central axis X to the base end of the inner peripheral surface 15a of the tubular portion 15 in the direction orthogonal to the central axis X (hereinafter, also simply referred to as “distance d2”). Since the distance d1 and the distance d2 satisfy the relational expression d1>d2/2, the protrusion 11 has an annular groove 19 of a suitable width at a suitable position between the protrusion 11 and the tubular portion 15 of the spout 10. Can be formed. Specifically, when the distance d1 and the distance d2 satisfy the relational expression d1>d2/2, the groove portion 19 can be appropriately curved along the tubular portion 15, and for example, When the liquid pouring tool 100 is tilted for pouring the lotion, the lotion flows along the groove portion 19 toward the pouring position in a curved manner, and takes longer than when the lotion flows linearly. Can reach a position. Therefore, it becomes easy to visually recognize the dispensed state of the lotion, and it is possible to stably and easily dispense the lotion.
It can also be expected to make the user feel that the lotion has a viscosity and improve the expectation for the effect of the lotion.

前記距離ｄ１は、前記距離ｄ２に対する割合（ｄ１／ｄ２）が、化粧水を好適に湾曲させて流出させる観点から６０％以上が好ましく、更に好ましくは７０％以上である。また、同様の観点から１００％未満が好ましく、更に好ましくは９０％以下である。具体的には、好ましくは６０％以上１００％未満であり、更に好ましく７０％以上９０％以下である。 The ratio (d1/d2) of the distance d1 to the distance d2 is preferably 60% or more, and more preferably 70% or more, from the viewpoint of appropriately curving and applying the lotion. From the same viewpoint, it is preferably less than 100%, more preferably 90% or less. Specifically, it is preferably 60% or more and less than 100%, more preferably 70% or more and 90% or less.

なお、本発明の注出キャップ１は、筒状部１５の周方向の一部のみにおいて、距離ｄ１と、距離ｄ２とが、関係式ｄ１＞ｄ２／２を満たしていても良い。しかし、本発明の効果がより確実に奏されるようにする観点から、前記距離ｄ１と前記距離ｄ２とが、関係式ｄ１＞ｄ２／２を満たす角度範囲は、筒状部１５の全周に亘って前記を満たす場合の角度範囲を３６０°としたときに、好ましくは１２０°以上３６０°以下、より好ましくは１８０°以上３６０°以下、更に好ましくは２４０°以上３６０°以下である。 In the pouring cap 1 of the present invention, the distance d1 and the distance d2 may satisfy the relational expression d1>d2/2 only in a part of the tubular portion 15 in the circumferential direction. However, from the viewpoint of ensuring that the effects of the present invention are exhibited, the angular range in which the distance d1 and the distance d2 satisfy the relational expression d1>d2/2 is the entire circumference of the tubular portion 15. When the angle range for satisfying the above condition is 360°, it is preferably 120° or more and 360° or less, more preferably 180° or more and 360° or less, and still more preferably 240° or more and 360° or less.

また、突出部１１は、上部が封止された筒状の円錐台形状に形成されており、上部を封止する天面部１７と、天面部１７と底部１６とを連結し、筒状部１５との間に環状の溝部１９を形成する外周部１８とを有している。
このように、本実施形態の突出部１１は、天面部１７と底部１６との間に天面部１７と底部１６とを連結する外周部１８を備えている。言い換えると、天面部１７の内方且つ底部１６の上方に空間が設けられるように外周部１８が設けられている。外周部１８を設けることで、外周部１８に複数の流出孔１２ａ〜１２ｄを形成した場合に、複数の流出孔１２ａ〜１２ｄから容器２内に化粧水が戻り易くなる。例えば、粘度の高い化粧水や液状内容物の場合、流出孔１２ａ〜１２ｄに膜をはり易くなり、容器２にスクイズ性があると容器２を把持した際に、流出孔１２ａ〜１２ｄにシャボン玉のような泡ができやすくなる。しかし、上記構成にすることで、流出孔１２ａ〜１２ｄに膜がはられ難くなり、膜がはられた場合でも膜が除去され易くなる。つまり、容器２内に化粧水が戻り易くなり、化粧水が容器２内に戻り易くなることで、注出口部１０内に化粧水が滞留することが防止され、注出口部１０からの不要な液漏れを防止することができる。 The protrusion 11 is formed in a cylindrical truncated cone shape with an upper part sealed, and the top part 17 that seals the upper part and the top part 17 and the bottom part 16 are connected to each other to form the cylindrical part 15. And an outer peripheral portion 18 forming an annular groove portion 19 between the outer peripheral portion 18 and the outer peripheral portion 18.
As described above, the protruding portion 11 of the present embodiment includes the outer peripheral portion 18 that connects the top surface portion 17 and the bottom portion 16 between the top surface portion 17 and the bottom portion 16. In other words, the outer peripheral portion 18 is provided so that a space is provided inside the top surface portion 17 and above the bottom portion 16. By providing the outer peripheral portion 18, when a plurality of outflow holes 12a to 12d are formed in the outer peripheral portion 18, the lotion easily returns to the container 2 from the plurality of outflow holes 12a to 12d. For example, in the case of a lotion or liquid content having a high viscosity, it is easy to put a film on the outflow holes 12a to 12d, and if the container 2 has a squeeze property, when the container 2 is gripped, soap bubbles will flow into the outflow holes 12a to 12d. It is easy to form bubbles like. However, with the above configuration, it becomes difficult for the film to be deposited on the outflow holes 12a to 12d, and even if the film is deposited, the film is easily removed. In other words, the lotion easily returns to the container 2, and the lotion easily returns to the container 2, so that the lotion is prevented from staying in the spout portion 10 and unnecessary from the spout portion 10. Liquid leakage can be prevented.

図３に示すように、天面部１７は、平面視において、略円形状に形成されており、その中心が中心軸Ｘ上に位置すると共に、中心軸Ｘ（図２参照）に対して略直交するように設けられている。天面部１７を設けることで、外周部１８に設けられる複数の流出孔１２ａ〜１２ｄを見え難くすることが可能になり、注出キャップ１を上方から見た際の美観を向上させることができる。また、天面部１７を設けることで、化粧水を注出するために液体注出具１００を傾けた際に、容器２内の化粧水を天面部１７の内面に衝突させて化粧水の勢いを低減させることができる。更に天面部１７を設けることで、その内方に空間が設けられ、流出孔の膜の形成を阻害することができる。 As shown in FIG. 3, the top surface portion 17 is formed in a substantially circular shape in a plan view, its center is located on the central axis X, and is substantially orthogonal to the central axis X (see FIG. 2). It is provided to do. By providing the top surface portion 17, it is possible to make the plurality of outflow holes 12a to 12d provided in the outer peripheral portion 18 less visible, and it is possible to improve the aesthetics when the pouring cap 1 is viewed from above. Further, by providing the top surface portion 17, when the liquid pouring tool 100 is tilted for pouring out the lotion, the lotion in the container 2 collides with the inner surface of the top surface portion 17 to reduce the momentum of the lotion. Can be made. Further, by providing the top surface portion 17, a space is provided inside the top surface portion 17 and the formation of the film of the outflow hole can be hindered.

図２に示すように、外周部１８は、筒状の円錐台形状（上方が開口した円錐台形状）に形成されており、外周部１８の外周面１８ａと筒状部１５の内周面１５ａとの間に環状の溝部１９を形成している。図３に示すように、外周部１８は、中心軸Ｘから外周面１８の基端までの前述した距離ｄ１が、前述した距離ｄ２の半分よりも大きくなるように形成されている。言い換えると、外周部１８は、距離ｄ１と距離ｄ２とが関係式ｄ１＞ｄ２／２を満たすように形成されている。 As shown in FIG. 2, the outer peripheral portion 18 is formed in a cylindrical truncated cone shape (conical truncated cone shape with an upper opening), and the outer peripheral surface 18 a of the outer peripheral portion 18 and the inner peripheral surface 15 a of the cylindrical portion 15 are formed. An annular groove portion 19 is formed between and. As shown in FIG. 3, the outer peripheral portion 18 is formed such that the distance d1 described above from the central axis X to the base end of the outer peripheral surface 18 is larger than half the distance d2 described above. In other words, the outer peripheral portion 18 is formed so that the distance d1 and the distance d2 satisfy the relational expression d1>d2/2.

複数の流出孔１２ａ〜１２ｄは、略矩形状に形成され、それぞれ突出部１１の外周部１８に形成されている。複数の流出孔１２ａ〜１２ｄを外周部１８に設けることで、前述したように、化粧水の容器２内への化粧水の戻り性が向上する。なお、複数の流出孔１２ａ〜１２ｄの形状は略矩形状に限らず、円形や多角形状であっても良い。 The plurality of outflow holes 12a to 12d are formed in a substantially rectangular shape, and are formed on the outer peripheral portion 18 of the protruding portion 11, respectively. By providing the plurality of outflow holes 12a to 12d in the outer peripheral portion 18, as described above, the returning property of the lotion into the container 2 of the lotion is improved. The shapes of the plurality of outflow holes 12a to 12d are not limited to the substantially rectangular shape, and may be circular or polygonal.

また図３及び図４に示すように、複数の流出孔１２ａ〜１２ｄのうち、流出孔１２ａと流出孔１２ｂとは中心軸Ｘを挟んで相対向する位置に形成され、流出孔１２ｃと流出孔１２ｄとは中心軸Ｘを挟んで相対向する位置に設けられている。つまり、本実施形態では、複数の流出孔１２ａ〜１２ｄは、中心軸Ｘを挟んで相対向する位置に設けられた一対の流出孔を２対有する構成となっている。このように、１対の流出孔１２ａ，１２ｂを設けることで、一方が空気孔となり、他方が流出孔となった場合にそれぞれの孔が最も離れた位置になり、一方の孔から液が吐出され、他方の孔が液でふさがれにくくなるため、空気置換がスムーズになり、脈動することなく吐出することができる。
しかし、本発明の効果がより確実に奏されるようにする観点から、複数の流出孔は２対以上有することが好ましく、本実施形態のように、２対の流出孔１２ａ〜１２ｄを設けることで、傾ける場所によらず安定した吐出を可能とし、また溝部１９から内周面１５を伝って、ゆっくり液を吐出させることができる。
また、複数の流出孔１２ａ〜１２ｄは、筒状部１５の周方向に等間隔に配されることが好ましい。本実施形態では、複数の流出孔１２ａ〜１２ｄは、筒状部１５をその周方向に３６０度に分割した時に、９０度の間隔で配置されている。流出孔１２ａ〜１２ｄを筒状部１５の周方向に等間隔で配することで、傾ける場所によらず、空気置換経路と液吐出経路を確実に分離できるため、流量のバラつきをなくし安定した吐出を可能にできる。特に、本実施形態のように、９０度の間隔で配置することで、天面部１７を４か所の外周部１８で安定保持できるため、後述するオーバーキャップ３の第２シール部３２と天面部１７の強固な連結が可能となり、液シール構造を確保できる。 Further, as shown in FIGS. 3 and 4, among the plurality of outflow holes 12a to 12d, the outflow holes 12a and the outflow holes 12b are formed at positions facing each other with the central axis X interposed therebetween, and the outflow holes 12c and the outflow holes 12c. 12d is provided at a position facing each other with the central axis X therebetween. That is, in the present embodiment, the plurality of outflow holes 12a to 12d are configured to have two pairs of outflow holes provided at positions facing each other with the central axis X interposed therebetween. In this way, by providing the pair of outflow holes 12a and 12b, when one is an air hole and the other is an outflow hole, the respective holes are at the most distant positions, and the liquid is discharged from one of the holes. As a result, the other hole is less likely to be blocked by the liquid, so that the air can be replaced smoothly and can be discharged without pulsation.
However, from the viewpoint of ensuring that the effect of the present invention is exhibited more reliably, it is preferable that the plurality of outflow holes have two or more pairs, and two pairs of outflow holes 12a to 12d are provided as in the present embodiment. Thus, stable ejection can be performed regardless of the tilted position, and the liquid can be slowly ejected from the groove portion 19 along the inner peripheral surface 15.
Moreover, it is preferable that the plurality of outflow holes 12 a to 12 d be arranged at equal intervals in the circumferential direction of the tubular portion 15. In the present embodiment, the plurality of outflow holes 12a to 12d are arranged at intervals of 90 degrees when the tubular portion 15 is divided into 360 degrees in the circumferential direction. By arranging the outflow holes 12a to 12d at equal intervals in the circumferential direction of the tubular portion 15, the air replacement path and the liquid discharge path can be reliably separated regardless of the position where they are tilted, so that there is no variation in the flow rate and stable discharge is achieved. Can be possible. In particular, by arranging them at intervals of 90 degrees as in the present embodiment, the top surface portion 17 can be stably held by the four outer peripheral portions 18, so that the second sealing portion 32 and the top surface portion of the overcap 3 described later can be held. 17 can be firmly connected, and a liquid seal structure can be secured.

次に、上述した本発明の実施形態の注出キャップ１が取り付けられた液体注出具１００を使用した際の作用効果について説明する。図６には、注出キャップ１を介して、容器２内に収容された化粧水が注出される状態が示されている。
上述したように、本実施形態の液体注出具１００は、注出キャップ１の注出口部１０の内部に底部１６から突出する突出部１１が設けられており、突出部１１は、距離ｄ１と距離ｄ２とが、関係式ｄ１＞ｄ２／２を満たすように形成されている。突出部１１は、距離ｄ１と距離ｄ２とが関係式ｄ１＞ｄ２／２を満たすように形成することで、注出口部１０の筒状部１５との間の好適な位置に、好適な幅の環状の溝部１９を形成することができる。具体的には、距離ｄ１と距離ｄ２とが関係式ｄ１＞ｄ２／２を満たすようにすることで、溝部１９を好適に湾曲させた形状にすることが可能になり、例えば、化粧水を注出するために液体注出具１００を傾けた際に、化粧水が溝部１９に沿って注出位置に向けて湾曲して流れ、直線的に流れる場合よりも時間をかけて注出位置に到達させることができる。そのため、化粧水の注出状態が視認し易くなり、化粧水の注出を安定して容易に行うことができる。また、使用者に化粧水が粘度を有しているように感じさせ、化粧水の効果に対する期待感を向上させることが期待できる。 Next, an operation effect when using the liquid pouring tool 100 to which the above-mentioned pouring cap 1 of the embodiment of the present invention is attached is explained. FIG. 6 shows a state in which the lotion contained in the container 2 is poured out via the pouring cap 1.
As described above, in the liquid spouting tool 100 of the present embodiment, the projecting portion 11 that projects from the bottom portion 16 is provided inside the spouting portion 10 of the spouting cap 1, and the projecting portion 11 has a distance d1 and a distance d1. d2 and d2 are formed so as to satisfy the relational expression d1>d2/2. The protrusion 11 is formed such that the distance d1 and the distance d2 satisfy the relational expression d1>d2/2, so that the protrusion 11 has a suitable width at a suitable position between the protruding portion 11 and the tubular portion 15 of the spout 10. The annular groove portion 19 can be formed. Specifically, by setting the distance d1 and the distance d2 to satisfy the relational expression d1>d2/2, it becomes possible to make the groove 19 have a curved shape, for example, by pouring a lotion. When the liquid pouring tool 100 is tilted for pouring, the lotion travels along the groove 19 toward the pouring position in a curved manner, and reaches the pouring position in a longer time than in the case of flowing straightly. be able to. Therefore, it becomes easy to visually recognize the dispensed state of the lotion, and it is possible to stably and easily dispense the lotion. Further, it can be expected that the user feels that the lotion has a viscosity, and the expectation for the effect of the lotion is improved.

更に、筒状部１５は、中心軸Ｘ方向の高さＨ１が距離ｄ１よりも長くなるように形成されている。筒状部１５の中心軸Ｘ方向の高さＨ１を突出部１１の中心軸Ｘ方向の高さＨ２よりも高くすることで流出孔１２ａ〜１２ｄから流れ出した化粧水の視認が更に容易となり、上述した化粧水の流出状態の調整が更に容易となる。また複数の流出孔１２ａ〜１２ｄから化粧水が合流しやすくなる。特に本実施形態では、筒状部１５の中心軸Ｘ方向の高さＨ１を距離ｄ１よりも高くしているので、より一層、流出孔１２ａ〜１２ｄから流れ出した化粧水の視認が容易となり、上述した化粧水の流出状態の調整が容易となる。
更に、筒状部１５の中心軸Ｘ方向の高さを全周に亘って同じ高さにすることで、化粧水を注出する際の液体注出具１００の傾斜方向にかかわらず、筒状部１５の何れの箇所からも化粧水を同じように注出させることができる。 Further, the tubular portion 15 is formed such that the height H1 in the central axis X direction is longer than the distance d1. By making the height H1 of the cylindrical portion 15 in the central axis X direction higher than the height H2 of the protruding portion 11 in the central axis X direction, it becomes easier to visually recognize the lotion flowing out from the outflow holes 12a to 12d. It becomes easier to adjust the outflow state of the applied lotion. In addition, the lotion easily joins from the plurality of outflow holes 12a to 12d. In particular, in this embodiment, the height H1 of the tubular portion 15 in the central axis X direction is set to be higher than the distance d1, so that the lotion that has flowed out from the outflow holes 12a to 12d becomes easier to see, and It becomes easy to adjust the outflow state of the applied lotion.
Furthermore, by making the height of the tubular portion 15 in the central axis X direction the same over the entire circumference, regardless of the inclination direction of the liquid pouring tool 100 when pouring the lotion, the tubular portion 15 The lotion can be similarly poured out from any of the positions of 15.

前述した一又は二以上の効果がより確実に得られるようにする観点から、注出キャップ１及び液体注出具１００は、以下の構成の一又は二以上を有することが更に好ましい。
筒状部１５の中心軸Ｘ方向の高さＨ１は、前記Ｈ２に対して２００％以上が好ましく、より好ましくは３００％以上であり、また１０００％以下が好ましく、より好ましくは８００％以下である。具体的には、２００％以上１０００％以下が好ましく、より好ましくは３００％以上８００％以下である。
また筒状部１５の中心軸Ｘ方向の高さＨ１は、前記ｄ１に対して１０５％以上が好ましく、より好ましくは１１０％以上であり、また３００％以下が好ましく、より好ましくは２００％以下である。具体的には、１０５％以上３００以下が好ましく、より好ましくは１１０％以上２００％以下である。 From the viewpoint of more reliably obtaining the above-mentioned one or more effects, it is more preferable that the spout cap 1 and the liquid spout 100 have one or more of the following configurations.
The height H1 of the tubular portion 15 in the direction of the central axis X is preferably 200% or more, more preferably 300% or more, and preferably 1000% or less, more preferably 800% or less, with respect to the H2. .. Specifically, it is preferably 200% or more and 1000% or less, and more preferably 300% or more and 800% or less.
Further, the height H1 of the tubular portion 15 in the direction of the central axis X is preferably 105% or more, more preferably 110% or more, and preferably 300% or less, more preferably 200% or less, with respect to the d1. is there. Specifically, it is preferably 105% or more and 300% or less, and more preferably 110% or more and 200% or less.

突出部１１の基端と筒状部１５の内周面１５ａ側の先端とを結ぶ線と、注出口部１０の底部１６とのなす角度、具体的には、突出部１１の外周部１８の外周面１８ａ側の基端と筒状部１５の内周面１５ａ側の先端とを結ぶ線と、注出口部１０の底部１６の上面１６ａとのなす角度θ（以下、単に「なす角度θ」ともいう）は、液状内容物の注出のし易さの観点から、３０°以上が好ましく、より好ましくは４５°以上である。また、９０°未満が好ましく、より好ましくは８５°以下である。具体的には、３０°以上９０°未満であることが好ましく、より好ましくは４５°以上８５°以下である。 An angle formed by a line connecting the base end of the protruding portion 11 and the tip of the cylindrical portion 15 on the inner peripheral surface 15a side and the bottom portion 16 of the spout 10, specifically, the outer peripheral portion 18 of the protruding portion 11. An angle θ formed by a line connecting the base end on the outer peripheral surface 18a side and the tip on the inner peripheral surface 15a side of the tubular portion 15 and the upper surface 16a of the bottom portion 16 of the spout 10 (hereinafter, simply “angle θ”). It is also preferably 30° or more, more preferably 45° or more, from the viewpoint of ease of pouring out the liquid content. Further, it is preferably less than 90°, more preferably 85° or less. Specifically, it is preferably 30° or more and less than 90°, more preferably 45° or more and 85° or less.

また本実施形態の液体注出具１００は、突出部１１の外周部１８に、周方向に等間隔で配置された２対の流出孔１２ａ〜１２ｄが設けられている。そのため、化粧水を注出するために液体注出具１００を傾けた際に、流出孔どうしが最も離れた一対の流出孔１２ａ，１２ｂ又は一対の流出孔１２ｃ，１２ｄから化粧水が流出し、且つ流出する化粧水が溝部１９に沿って湾曲した流路に沿って流出させることができる。またこのとき、図６に示すように、一対の流出孔１２ｃ，１２ｄから流出された化粧水は、筒状部１５の内周面上で収束し、筒状部１５の先端から線状に流出される。このように、直線的に流出する場合に比して、流出するまでの時間が多くなり、使用者に化粧水の粘度を感じさせることができる。言い換えると、使用者に化粧水のとろみを感じさせることができる。その結果、使用者が化粧水の効果に対する期待感を向上させることが期待できる。 Further, in the liquid pouring tool 100 of the present embodiment, two pairs of outflow holes 12a to 12d arranged at equal intervals in the circumferential direction are provided on the outer peripheral portion 18 of the protruding portion 11. Therefore, when the liquid pouring tool 100 is tilted for pouring the lotion, the lotion flows out from the pair of outflow holes 12a and 12b or the pair of outflow holes 12c and 12d whose outflow holes are most distant from each other, and The lotion that flows out can be made to flow out along the flow path curved along the groove 19. Further, at this time, as shown in FIG. 6, the lotion that has flowed out from the pair of outflow holes 12c and 12d converges on the inner peripheral surface of the tubular portion 15 and linearly flows out from the tip of the tubular portion 15. To be done. In this way, compared to the case where the liquid flows out linearly, the time until the liquid flows out becomes longer, and the user can feel the viscosity of the lotion. In other words, the user can feel the thickening of the lotion. As a result, it can be expected that the user's expectation for the effect of the lotion will be improved.

また、本実施形態の液体注出具１００は、容器２の口部２１に取付け部１３を取り付けた際に、口部２１の近傍に注出口部の１０の筒状部１５が位置している。具体的には、口部に隣接するように筒状部１５が位置している。そのため、容器２内の化粧水を視認しながら、筒状部１５から容易に注出することができる。 In addition, in the liquid pouring tool 100 of the present embodiment, when the mounting portion 13 is attached to the mouth portion 21 of the container 2, the ten tubular portions 15 of the spout portion are located near the mouth portion 21. Specifically, the tubular portion 15 is located so as to be adjacent to the mouth portion. Therefore, it is possible to easily pour out the toner from the tubular portion 15 while visually checking the toner in the container 2.

また本実施形態では、複数の流出孔１２ａ〜１２ｄは、総面積（合計面積）が、外周部１８の外周面１８ａの複数の流出孔１２ａ〜１２ｄの総面積を除いた面積、もしくは、突出部１１の表面積の、複数の流出孔１２ａ〜１２ｄの総面積を除いた面積よりも小さくなるように形成されている。そのため、化粧水等のような粘度の低い剤をコントロールしながら取り出したい位置に適量を取り出すことができる。 Further, in the present embodiment, the total area (total area) of the plurality of outflow holes 12a to 12d is the area excluding the total area of the plurality of outflow holes 12a to 12d of the outer peripheral surface 18a of the outer peripheral portion 18, or the protruding portion. The surface area of 11 is smaller than the total area of the plurality of outflow holes 12a to 12d. Therefore, an appropriate amount can be taken out at a desired position while controlling a low-viscosity agent such as lotion.
