Description

本発明は、容器の口部に装着されて該容器に収容された内容液を注出筒から注出する注出キャップに関する。 The present invention relates to a dispensing cap that is attached to the mouth of a container and dispenses the content liquid contained in the container from the dispensing cylinder.

化粧水などの化粧料、シャンプーやリンス、液体石鹸あるいは食品調味料などの内容液を収容する容器の口部には、適量の内容液を容易に注出可能とするために注出キャップが装着されるのが一般的である。 A pouring cap is attached to the mouth of the container that contains cosmetics such as lotion, shampoo, conditioner, liquid soap, or food seasonings so that an appropriate amount of liquid can be easily poured. It is common to be done.

例えば特許文献1には、外層体の内側に内容液を収容する内層体を剥離可能に積層配置してなる積層剥離容器の口部に装着される注出キャップとして、内容液の注出口となる注出筒が上面に一体に設けられる頂壁部とこの頂壁部の外周に一体に連ねて設けられるとともに口部の外周にねじ込み等により装着される装着筒部とを備えるキャップ本体と、注出筒に連なる円筒部と該円筒部の下端に一体に連なり下方に向けて徐々に縮径する縮径筒部とを備えた保持筒と、円筒部の内面に設けられた抜け止め突起と縮径筒部との間で移動自在に保持筒の内部に配置されて縮径筒部の下端に設けられた開口を開閉するボール弁と、を備えた構成のものが記載されている。 For example, in Patent Document 1, as a pouring cap attached to the mouth of a laminated stripping container in which an inner layer containing a content liquid is laminated and arranged so as to be peelable inside the outer layer, the content liquid is dispensed. A cap body having a top wall portion integrally provided on the upper surface of the injection cylinder and a mounting cylinder portion integrally provided on the outer periphery of the top wall portion and mounted on the outer circumference of the mouth portion by screwing or the like. A holding cylinder having a cylindrical portion connected to the ejection cylinder and a reduced diameter cylinder portion integrally connected to the lower end of the cylindrical portion and gradually reducing the diameter downward, and a retaining protrusion and shrinkage provided on the inner surface of the cylindrical portion. A ball valve that is movably arranged inside a holding cylinder and opens and closes an opening provided at the lower end of the diameter-reduced cylinder portion is described.

このような注出キャップが装着された積層剥離容器では、外層体の胴部をスクイズ(押圧)して内容液を注出筒から注出させることができるとともに、スクイズの解除後は、ボール弁により保持筒の開口つまり注出筒を閉じつつ外層体に設けた外気導入孔から外層体と内層体との間に外気を導入することにより、内層体を減容変形させたまま胴部を復元させることができる。これにより、注出された内容液と置換されて内層体の内部に外気が吸入されることを防止して、内容液の外気との接触を抑制し、その品質を維持することができる。 In the laminated peeling container equipped with such a pouring cap, the body of the outer layer body can be squeezed (pressed) to pour the content liquid from the pouring cylinder, and after the squeeze is released, the ball valve can be used. By introducing outside air between the outer layer body and the inner layer body through the outside air introduction hole provided in the outer layer body while closing the opening of the holding cylinder, that is, the injection cylinder, the body is restored while the inner layer body is reduced in volume and deformed. Can be made to. As a result, it is possible to prevent the content liquid from being replaced with the poured content liquid and inhaling the outside air into the inner layer body, suppress the contact of the content liquid with the outside air, and maintain the quality thereof.

(a)は、本発明の一実施形態に係る注出キャップの注出筒部分の平面図であり、(b)は、本発明の一実施形態に係る注出キャップを容器の口部に装着した状態を示す正面断面図である。(A) is a plan view of the dispensing cylinder portion of the dispensing cap according to the embodiment of the present invention, and (b) is the dispensing cap according to the embodiment of the present invention attached to the mouth of the container. It is a front sectional view which shows the state which was done.

以下、図面を参照して、本発明をより具体的に例示説明する。なお、本願明細書、特許請求の範囲、要約書、及び図面では、容器10の正立姿勢を基準としており、後述する蓋体50が位置する側を上方(図1における上側)とし、容器10が配置される側を下方(図1における下側)とする。 Hereinafter, the present invention will be described in more detail with reference to the drawings. In the specification of the present application, claims, abstract, and drawings, the upright posture of the container 10 is used as a reference, and the side where the lid 50, which will be described later, is located is upward (upper side in FIG. 1), and the container 10 is used. The side on which is placed is the lower side (lower side in FIG. 1).

図1(b)に示す本発明の一実施形態である注出キャップ1は、化粧水などの化粧料、シャンプーやリンス、液体石鹸あるいは食品調味料などの内容物を収容する容器10の口部11に装着されて容器10に収容された内容物を外部に注出するものである。 The injection cap 1, which is an embodiment of the present invention shown in FIG. 1 (b), is the mouth of a container 10 for containing cosmetics such as lotion, shampoo, conditioner, liquid soap, food seasonings, and the like. The contents mounted on the 11 and contained in the container 10 are poured out to the outside.

本実施の形態では、容器10は、外層体12と外層体12の内側に外層体12に対して剥離可能に積層配置される内層体13とを有する積層剥離容器として形成されている。この場合、図示しない容器10の底部には外層体12と内層体13との間の空間に外気を導入するため、ピンチオフ部にスリットが設けられ、容器10の胴部(不図示)がスクイズ(押圧)されると内容物が注出キャップ1から外部に注出される一方、胴部のスクイズの解除後は、ピンチオフ部のスリットから外層体12と内層体13との間に外気が導入されて内層体13を減容変形させたまま胴部が復元する。これにより、注出された内容物と置換されて内層体13の内部に外気が吸入されることを防止して、内容物の外気との接触を抑制して、その品質を維持することができる。 In the present embodiment, the container 10 is formed as a laminated peeling container having an outer layer body 12 and an inner layer body 13 which is vertically arranged so as to be peelable from the outer layer body 12 inside the outer layer body 12. In this case, in order to introduce outside air into the space between the outer layer 12 and the inner layer 13 at the bottom of the container 10 (not shown), a slit is provided in the pinch-off portion, and the body (not shown) of the container 10 is squeezed (not shown). When pressed), the contents are poured out from the pouring cap 1, and after the squeeze of the body is released, outside air is introduced between the outer layer 12 and the inner layer 13 through the slit in the pinch-off portion. The body is restored while the inner layer 13 is reduced in volume and deformed. As a result, it is possible to prevent the outside air from being sucked into the inner layer 13 by being replaced with the injected contents, suppress the contact of the contents with the outside air, and maintain the quality thereof. ..

なお、外気導入は、必ずしも容器10の底部のピンチオフ部のスリットに設けられている必要はなく、例えば、容器10の口部11に外気導入孔を設けて外層体12と内層体13の間の空間に外気を導入するなどしてもよい。尚、口部10に外気導入孔を設ける場合には、キャップ本体20の頂壁部21に外気導入用の開孔部を形成し、且つキャップ本体内面と口部11外面との間に外気連通路を設け、外気導入孔と連通させる。 The outside air introduction does not necessarily have to be provided in the slit of the pinch-off portion at the bottom of the container 10. For example, an outside air introduction hole is provided in the mouth portion 11 of the container 10 between the outer layer body 12 and the inner layer body 13. Outside air may be introduced into the space. When an outside air introduction hole is provided in the mouth portion 10, an opening portion for introducing outside air is formed in the top wall portion 21 of the cap body 20, and an outside air connection is formed between the inner surface of the cap body and the outer surface of the mouth portion 11. A passage will be provided to communicate with the outside air introduction hole.

この注出キャップ1は、キャップ本体20、保持筒30、弁体40及び蓋体50を備えている。 The dispensing cap 1 includes a cap body 20, a holding cylinder 30, a valve body 40, and a lid body 50.

キャップ本体20は、略円板状に形成される頂壁部21と、頂壁部21の外周に一体に連ねて設けられる円筒状の装着筒部22とを備えた有頂円筒状に形成され、装着筒部22が口部11の外周を囲い、且つ、頂壁部21が口部11の開口端に当接するように口部11に装着される。なお、頂壁部21の下面には、図示するように、装着筒部22よりも小径に形成されて口部11の内周面に液密に当接するシール筒23を一体に設けることもできる。 The cap body 20 is formed in an ecstatic cylindrical shape including a top wall portion 21 formed in a substantially disk shape and a cylindrical mounting cylinder portion 22 provided integrally connected to the outer periphery of the top wall portion 21. , The mounting cylinder portion 22 surrounds the outer periphery of the mouth portion 11, and the top wall portion 21 is mounted on the mouth portion 11 so as to abut on the open end of the mouth portion 11. As shown in the figure, the lower surface of the top wall portion 21 may be integrally provided with a seal cylinder 23 having a diameter smaller than that of the mounting cylinder portion 22 and in close contact with the inner peripheral surface of the mouth portion 11. ..

装着筒部22の内周面には、その下端側に位置して被係合突起22aが設けられており、この被係合突起22aが口部11の外周面に設けられた係合突起11aにアンダーカット係合することにより、キャップ本体20は口部11に抜け止めされた状態で装着されている。つまり、この注出キャップ1は、キャップ本体20が口部11に打栓により装着される構成となっている。また、口部11の外周面には、位置決めリブ11bが設けられている。上記打栓の際に、位置決めリブ11bが装着筒部22の内周面に設けられているリブ22b間に入り込むことによってキャップ本体20が容器10に対して回動しないように構成されている。 An engaged protrusion 22a is provided on the inner peripheral surface of the mounting cylinder portion 22 at the lower end side thereof, and the engaged projection 22a is provided on the outer peripheral surface of the mouth portion 11. The cap body 20 is attached to the mouth portion 11 in a state of being prevented from coming off by engaging with the undercut. That is, the dispensing cap 1 has a configuration in which the cap body 20 is attached to the mouth portion 11 by tapping. Further, a positioning rib 11b is provided on the outer peripheral surface of the mouth portion 11. At the time of the plugging, the positioning rib 11b is inserted between the ribs 22b provided on the inner peripheral surface of the mounting cylinder portion 22 so that the cap body 20 does not rotate with respect to the container 10.

頂壁部21の上面には内容物を外部に注出する注出口24aを形成する注出筒24が一体に設けられている。注出筒24は頂壁部21との接続部分から上方に向けて徐々に拡径しながら外向きに湾曲する形状に形成されている。 A pouring cylinder 24 forming a pouring outlet 24a for pouring the contents to the outside is integrally provided on the upper surface of the top wall portion 21. The dispensing cylinder 24 is formed in a shape that curves outward while gradually increasing its diameter upward from the connection portion with the top wall portion 21.

キャップ本体20は、蓋体50を一体に備えた構成とすることもできる。蓋体50は、キャップ本体20と略同径の有頂円筒状に形成され、その外周面においてヒンジ28を介してキャップ本体20に一体に連結されている。蓋体50は、その開口内周面に設けられた係止溝50aが頂壁部21の外周縁に設けられた係止突起21aにアンダーカット係合することにより閉じた状態に保持される。蓋体50が閉じられると、注出筒24が蓋体50の天壁56に覆われるとともに、蓋体50の天壁56の下面から垂下するシール用突起52が注出筒24の内周面に嵌合して注出筒24がシール用突起52により閉塞される。 The cap body 20 may be configured to integrally include the lid body 50. The lid 50 is formed in an eclipsed cylindrical shape having substantially the same diameter as the cap body 20, and is integrally connected to the cap body 20 via a hinge 28 on the outer peripheral surface thereof. The lid 50 is held in a closed state by undercut engagement of the locking groove 50a provided on the inner peripheral surface of the opening with the locking projection 21a provided on the outer peripheral edge of the top wall portion 21. When the lid 50 is closed, the pouring cylinder 24 is covered with the top wall 56 of the lid 50, and the sealing protrusion 52 hanging from the lower surface of the top wall 56 of the lid 50 is the inner peripheral surface of the pouring cylinder 24. The pouring cylinder 24 is closed by the sealing protrusion 52.

シール用突起52は、図1(b)に示すように、蓋体50の閉塞時において下方に向けて徐々に縮径するように構成され、下端部52aには、シール用突起52よりも更に小径の突部54が形成されている。このように、シール用突起52を下方に向けて縮径して構成することにより、下端部52aを上方に向けて拡径する注出筒24の基部24bに対して確実に当接させることができる。 As shown in FIG. 1B, the sealing protrusion 52 is configured to gradually reduce its diameter downward when the lid 50 is closed, and the lower end portion 52a has a further diameter than the sealing protrusion 52. A small-diameter protrusion 54 is formed. By forming the sealing protrusion 52 with a reduced diameter downward in this way, the lower end portion 52a can be reliably brought into contact with the base portion 24b of the dispensing cylinder 24 whose diameter is increased upward. it can.

なお、本実施形態では、蓋体50をヒンジ28周りに回動させて開閉させるように構成されているため、注出筒24の形状は蓋体50の開閉時にシール用突起52と干渉しないように、図1(a)に示す平面視で楕円形状にて形成されている。そして、蓋体50の開閉時の下端部52aの軌跡が、図1(b)に一点鎖線で示すように注出筒24の内周面に沿って移動するように構成されている。ここで、注出筒24の内周面とシール用突起52の下端部52aが描く軌跡との最小距離d1は、部材の寸法公差等を考慮しても注出筒24とシール用突起52とが接触しないような距離となっており、蓋体50を閉塞したときの注出筒24とシール用突起52との隙間Gを最小化できるため、内容物の粘度が高くても、隙間Gに残る内容物の容積を小さくして注出口24aや蓋体50を汚れにくくすることができる。 In the present embodiment, since the lid 50 is configured to be rotated around the hinge 28 to open and close, the shape of the dispensing cylinder 24 does not interfere with the sealing protrusion 52 when the lid 50 is opened and closed. In addition, it is formed in an elliptical shape in a plan view shown in FIG. 1 (a). Then, the locus of the lower end portion 52a when the lid body 50 is opened and closed is configured to move along the inner peripheral surface of the pouring cylinder 24 as shown by the alternate long and short dash line in FIG. 1 (b). Here, the minimum distance d1 between the inner peripheral surface of the pouring cylinder 24 and the locus drawn by the lower end portion 52a of the sealing protrusion 52 is the same as that of the pouring cylinder 24 and the sealing protrusion 52 even if the dimensional tolerance of the member is taken into consideration. Since the distance is set so that the lids do not come into contact with each other and the gap G between the dispensing cylinder 24 and the sealing protrusion 52 when the lid 50 is closed can be minimized, even if the viscosity of the contents is high, the gap G The volume of the remaining contents can be reduced to prevent the spout 24a and the lid 50 from becoming dirty.

なお、図1(b)に示すように、ヒンジ28の反対側(図1(b)の左側)、及び図1(b)の紙面に垂直方向における注出筒24の内周面とシール用突起52との隙間Gについては、蓋体50の閉塞時において、シール用突起52の外周面と注出筒24の内周面との最小距離d2が、部材の寸法公差等を考慮しても注出筒24とシール用突起52とが接触しないような距離となるように構成されている。 As shown in FIG. 1 (b), the inner peripheral surface of the dispensing cylinder 24 and the seal in the direction opposite to the hinge 28 (left side of FIG. 1 (b)) and the paper surface of FIG. 1 (b). Regarding the gap G with the protrusion 52, when the lid 50 is closed, the minimum distance d2 between the outer peripheral surface of the sealing protrusion 52 and the inner peripheral surface of the dispensing cylinder 24 is even if the dimensional tolerance of the member is taken into consideration. The distance is such that the dispensing cylinder 24 and the sealing protrusion 52 do not come into contact with each other.

なお、蓋体50はヒンジ28を介してキャップ本体20に一体に連結される構成に限らず、例えばキャップ本体20にねじ係合や打栓係合により装着される構成とすることもできる。その場合、注出筒24の形状はシール用突起52の下端部52aが描く軌跡には依存しない。すなわち、蓋体50の閉塞状態(図1(b)の状態)におけるシール用突起52の外周面と注出筒24の内周面との最小距離d2が、部材の寸法公差等を考慮しても注出筒24とシール用突起52とが接触しないような距離となるように構成されていればよい。この場合、注出筒24の形状は、必ずしも平面視で図1(a)のような楕円形状とはならず、例えばシール用突起52の横断面が円形状の場合、それに対応した円形状を有するように構成されるのが好ましい。 The lid 50 is not limited to being integrally connected to the cap body 20 via a hinge 28, and may be mounted on the cap body 20 by screw engagement or plug engagement, for example. In that case, the shape of the dispensing cylinder 24 does not depend on the locus drawn by the lower end portion 52a of the sealing protrusion 52. That is, the minimum distance d2 between the outer peripheral surface of the sealing protrusion 52 and the inner peripheral surface of the dispensing cylinder 24 in the closed state of the lid 50 (state of FIG. 1B) takes into consideration the dimensional tolerance of the member and the like. The distance may be such that the dispensing cylinder 24 and the sealing protrusion 52 do not come into contact with each other. In this case, the shape of the dispensing cylinder 24 does not necessarily have an elliptical shape as shown in FIG. 1A in a plan view. For example, when the cross section of the sealing protrusion 52 is a circular shape, a circular shape corresponding to the circular shape is formed. It is preferably configured to have.

保持筒30は円筒部31と屈曲部32とを有し、全体として円筒状に形成され、その内部は注出筒24に連なる内容物の流路となっている。この保持筒30はキャップ本体20と一体に形成されている。 The holding cylinder 30 has a cylindrical portion 31 and a bent portion 32, and is formed in a cylindrical shape as a whole, and the inside thereof is a flow path of contents connected to the pouring cylinder 24. The holding cylinder 30 is integrally formed with the cap body 20.

円筒部31は頂壁部21の下面から垂下して設けられ、この円筒部31の下端(容器10の収容空間S側を向く端)に屈曲部32が一体に連ねて設けられている。円筒部31は内径が略一定の円筒状に形成され、これに対して屈曲部32は下方に向けて徐々に内径が縮径する縮径部32aと、その後徐々に内径が拡径する拡径部32bとを有している。また、図示する場合では、屈曲部32の下端は保持筒30の開口34つまり内容物の流入口を構成している。 The cylindrical portion 31 is provided so as to hang down from the lower surface of the top wall portion 21, and the bent portion 32 is integrally connected to the lower end of the cylindrical portion 31 (the end facing the storage space S side of the container 10). The cylindrical portion 31 is formed in a cylindrical shape having a substantially constant inner diameter, whereas the bent portion 32 has a reduced diameter portion 32a whose inner diameter gradually decreases downward and an enlarged diameter portion whose inner diameter gradually increases thereafter. It has a part 32b. Further, in the case shown in the drawing, the lower end of the bent portion 32 constitutes the opening 34 of the holding cylinder 30, that is, the inflow port of the contents.

なお、屈曲部32は必ずしも縮径部32aと拡径部32bとを有している必要はなく、縮径部32aのみから構成されていてもよい。 The bent portion 32 does not necessarily have to have the reduced diameter portion 32a and the enlarged diameter portion 32b, and may be composed of only the reduced diameter portion 32a.

図1(b)に示すように、保持筒30の内部空間Mの天面30Uは、後述する球状の弁体40に対応した球弧面を有している。これによって、注出筒24内から後述するサックバック効果によって容器10の収容空間S方向へ戻された内容物が球弧面を有する天面30Uに沿って下方に流れ易くなる。従って、内容物の回収が容易となる。また、天面30Uにおける注出口24aの周囲には、周方向3箇所にリブ30Rが頂壁部21と一体に設けられている。これらのリブ30Rは、後述するように容器10の胴部の押圧により収容空間Sの内圧が高まることによって弁体40が注出口24a方向に持ち上げられ(弁体40が持ち上げられた状態を、図1に二点鎖線で示す。)、リブ30Rに当接した状態で、内容物をリブ30Rの間から注出口24aへと導く流路を形成するために設けられている。本実施形態では、天面30Uが、弁体40の球形状に対応した球弧面を有しているので、仮に天面30Uに内容物が残存しても、内容物の注出時に弁体40に押圧されリブ30Rの間から押し出されて注出口24aへと導くことができる。なお、リブ30Rは必ずしも周方向に3箇所設ける態様には限定されず、少なくとも1箇所に設けられていればよい。また、リブ30Rに依らず、円筒部31から注出口24aへと内容物を導くための溝を保持筒30の内面に設けるなどしてもよい。 As shown in FIG. 1B, the top surface 30U of the internal space M of the holding cylinder 30 has a spherical arc surface corresponding to the spherical valve body 40 described later. As a result, the contents returned from the inside of the pouring cylinder 24 toward the storage space S of the container 10 by the suckback effect described later can easily flow downward along the top surface 30U having the spherical arc surface. Therefore, the contents can be easily collected. Further, around the spout 24a on the top surface 30U, ribs 30R are provided integrally with the top wall portion 21 at three locations in the circumferential direction. As will be described later, in these ribs 30R, the valve body 40 is lifted in the direction of the injection port 24a by increasing the internal pressure of the accommodation space S by pressing the body portion of the container 10 (the state in which the valve body 40 is lifted is shown in FIG. 1 is shown by a two-dot chain line), which is provided to form a flow path that guides the contents from between the ribs 30R to the spout 24a in a state of being in contact with the rib 30R. In the present embodiment, since the top surface 30U has a spherical arc surface corresponding to the spherical shape of the valve body 40, even if the contents remain on the top surface 30U, the valve body is ejected when the contents are poured out. It can be pressed by 40 and pushed out from between the ribs 30R to lead to the spout 24a. The ribs 30R are not necessarily provided at three locations in the circumferential direction, and may be provided at at least one location. Further, regardless of the rib 30R, a groove for guiding the contents from the cylindrical portion 31 to the spout 24a may be provided on the inner surface of the holding cylinder 30.

弁体40は樹脂等により球状に形成され、保持筒30の内部に配置されている。弁体40は、直径が円筒部31の内径よりもやや小さくなるように形成されており、円筒部31の内周面と弁体40の外周面との間に内容物の流路が確保されるようになっている。 The valve body 40 is formed in a spherical shape by resin or the like, and is arranged inside the holding cylinder 30. The valve body 40 is formed so that the diameter is slightly smaller than the inner diameter of the cylindrical portion 31, and a flow path for the contents is secured between the inner peripheral surface of the cylindrical portion 31 and the outer peripheral surface of the valve body 40. It has become so.

また、図1(b)から分かるように、弁体40は、天面30U及び屈曲部32によって上下の移動が制限され、保持筒30の内部空間M内に弁体40の移動経路が区画形成されている。つまり、弁体40の直径は、注出口24aの直径及び屈曲部32の狭小部32cの径よりも大きくなっている。これにより、弁体40は天面30Uと屈曲部32との間で、円筒部31に沿って軸方向に移動自在となっている。なお、本実施形態では、シール用突起52と注出筒24との間の隙間Gの容積を小さくして内容物が残存しにくいように、注出口24aの大きさを小さく制限している。そのため、弁体40は開口34側から押し込み、屈曲部32を乗り越えるようにして内部空間M内に入れることができる。 Further, as can be seen from FIG. 1B, the valve body 40 is restricted from moving up and down by the top surface 30U and the bent portion 32, and the movement path of the valve body 40 is defined in the internal space M of the holding cylinder 30. Has been done. That is, the diameter of the valve body 40 is larger than the diameter of the spout 24a and the diameter of the narrow portion 32c of the bent portion 32. As a result, the valve body 40 is movable in the axial direction along the cylindrical portion 31 between the top surface 30U and the bent portion 32. In this embodiment, the size of the spout 24a is limited to a small size so that the volume of the gap G between the sealing protrusion 52 and the pouring cylinder 24 is reduced so that the contents are unlikely to remain. Therefore, the valve body 40 can be pushed in from the opening 34 side and entered into the internal space M so as to get over the bent portion 32.

利用者は、内容物を注出するために、まず蓋体50の把持部58を把持しながら上方に持ち上げて蓋体50を開放する。次に、注出キャップ1が下方側となるように容器10を傾斜させながらその胴部をスクイズすると、弁体40が屈曲部32から離れる方向に移動して開口34が開放され、円筒部31の内周面と弁体40の外周面との間に内容物の流路が確保される。これにより、容器10の収容空間S内の内容物が開口34から保持筒30に流入し、円筒部31の内周面と弁体40の外周面との間の流路を通って注出筒24から外部に注出される。 In order to pour out the contents, the user first grips the grip portion 58 of the lid body 50 and lifts it upward to open the lid body 50. Next, when the body portion of the container 10 is tilted so that the dispensing cap 1 is on the lower side, the valve body 40 moves in a direction away from the bent portion 32, the opening 34 is opened, and the cylindrical portion 31 is opened. A flow path for the contents is secured between the inner peripheral surface of the valve body 40 and the outer peripheral surface of the valve body 40. As a result, the contents in the accommodation space S of the container 10 flow into the holding cylinder 30 from the opening 34, and pass through the flow path between the inner peripheral surface of the cylindrical portion 31 and the outer peripheral surface of the valve body 40 to be a pouring cylinder. It is poured out from 24.

内容物の注出後、利用者が胴部のスクイズを解除し、容器10が注出キャップ1が上方側となる正立姿勢に戻されると、弁体40が保持筒30の内部を下方に向けて移動して屈曲部32に当接する。これにより、開口34つまり注出筒24が弁体40により閉塞され、注出筒24から容器10の内層体13内部への外気の導入が阻止される。また、弁体40が下方に移動することによって注出口24a近傍が負圧となり、注出筒24内に残存する内容物が保持筒30内に引き込まれる(サックバック効果)。一方、胴部はスクイズ解除に伴い自らの剛性によって元の形状に復元するため、外層体12と内層体13との間の容積が増大して負圧となり、図示しないピンチオフ部のスリットを経由して外層体12と内層体13との間の空間に空気が導入される。これにより、注出された内容物と置換されて内層体13の内部に外気が吸入されることを防止して、内容物の外気との接触を抑制して、その品質を維持することができる。 After pouring out the contents, when the user releases the squeeze of the body and the container 10 is returned to the upright posture with the pouring cap 1 on the upper side, the valve body 40 moves downward inside the holding cylinder 30. It moves toward and abuts on the bent portion 32. As a result, the opening 34, that is, the pouring cylinder 24 is closed by the valve body 40, and the introduction of outside air from the pouring cylinder 24 into the inner layer 13 of the container 10 is prevented. Further, as the valve body 40 moves downward, the vicinity of the injection port 24a becomes a negative pressure, and the contents remaining in the injection cylinder 24 are drawn into the holding cylinder 30 (suckback effect). On the other hand, since the body part is restored to its original shape by its own rigidity when the squeeze is released, the volume between the outer layer body 12 and the inner layer body 13 increases and becomes negative pressure, and the body portion passes through a slit in a pinch-off portion (not shown). Air is introduced into the space between the outer layer 12 and the inner layer 13. As a result, it is possible to prevent the outside air from being sucked into the inner layer 13 by being replaced with the injected contents, suppress the contact of the contents with the outside air, and maintain the quality thereof. ..

利用者は、容器10を正立姿勢に戻した後、蓋体50をヒンジ28周りに回動させて、再びキャップ本体20に係合させる。これによって、シール用突起52が注出筒24内に挿入されて注出口24aが閉塞される。このとき、図1(b)に示すようにシール用突起52の下端部52aから突出する小径の突部54が先に注出筒24に突入して注出筒24内に残存する内容物を内部空間M内に押し戻す。このため、注出筒24に残存する内容物を容易に回収することができる。また、図1(b)に示すように、蓋体50の閉塞時に突部54が注出口24aを貫通して内部空間M内に突出する。従って、万一内容物の注出時に弁体40が天面30Uに貼り付いても、蓋体50の閉塞時に突部54が弁体40を下方に押圧してその貼り付きを解除することができる。 After returning the container 10 to the upright posture, the user rotates the lid 50 around the hinge 28 and engages the cap body 20 again. As a result, the sealing protrusion 52 is inserted into the pouring cylinder 24 and the pouring outlet 24a is closed. At this time, as shown in FIG. 1B, the small-diameter protrusion 54 protruding from the lower end 52a of the sealing protrusion 52 first rushes into the dispensing cylinder 24, and the contents remaining in the dispensing cylinder 24 are removed. Push back into the internal space M. Therefore, the contents remaining in the dispensing cylinder 24 can be easily recovered. Further, as shown in FIG. 1B, when the lid 50 is closed, the protrusion 54 penetrates the spout 24a and protrudes into the internal space M. Therefore, even if the valve body 40 sticks to the top surface 30U when the contents are poured out, the protrusion 54 may press the valve body 40 downward to release the sticking when the lid 50 is closed. it can.

以上述べたように、本実施形態では、蓋体50は、蓋体50の天壁56から垂下するシール用突起52を有する。そして、蓋体50の閉塞時において、シール用突起52のうち少なくとも注出筒24と高さ方向に重なる部分の外周面は下方に向けて縮径し、注出筒24のうち少なくともシール用突起52と高さ方向に重なる部分の内周面は上方に向けて拡径し、シール用突起52は下部において注出筒24の内周面に当接するように構成した。これによって、小径のシール用突起52を小径の注出筒24に挿入して注出口24aを閉塞するので、注出筒24とシール用突起52との隙間Gの容積を最小化して注出筒24内の内容物の残量を低減することができる。従って、内容物の粘度が高くても、隙間G内の内容物の付着によって注出口24aや蓋体50が汚れにくい注出キャップ1を提供することができる。また、残った内容物を、縮径されたシール用突起52によって円筒部31内へ押し込み易くなっている。 As described above, in the present embodiment, the lid body 50 has a sealing protrusion 52 hanging from the top wall 56 of the lid body 50. Then, when the lid 50 is closed, at least the outer peripheral surface of the portion of the sealing protrusion 52 that overlaps with the dispensing cylinder 24 in the height direction is reduced in diameter downward, and at least the sealing protrusion of the dispensing cylinder 24. The inner peripheral surface of the portion overlapping with the 52 in the height direction is enlarged in diameter upward, and the sealing protrusion 52 is configured to abut on the inner peripheral surface of the dispensing cylinder 24 at the lower part. As a result, the small-diameter sealing protrusion 52 is inserted into the small-diameter pouring cylinder 24 to close the injection port 24a, so that the volume of the gap G between the pouring cylinder 24 and the sealing protrusion 52 is minimized and the pouring cylinder is closed. The remaining amount of the contents in 24 can be reduced. Therefore, even if the viscosity of the contents is high, it is possible to provide the pouring cap 1 in which the pouring outlet 24a and the lid 50 are not easily contaminated by the adhesion of the contents in the gap G. Further, the remaining contents can be easily pushed into the cylindrical portion 31 by the reduced diameter sealing protrusion 52.

また、本実施形態では、蓋体50がキャップ本体20にヒンジ28を介して連結されており、蓋体50の開閉時におけるシール用突起52が描く軌跡と注出筒24の内周面との最小距離d1を、部材の寸法公差等を考慮しても注出筒24とシール用突起52とが接触しないような距離とすることで、ヒンジ28周りに回転させて閉塞するタイプの蓋体50であっても注出筒24とシール用突起52との隙間Gの容積を最小化することができる。よって、部品点数を削減しつつ隙間G内の内容物の付着によって注出口24aや蓋体50が汚れにくい注出キャップ1を提供することができる。 Further, in the present embodiment, the lid body 50 is connected to the cap body 20 via a hinge 28, and the locus drawn by the sealing protrusion 52 when the lid body 50 is opened and closed and the inner peripheral surface of the dispensing cylinder 24. The minimum distance d1 is set so that the pouring cylinder 24 and the sealing protrusion 52 do not come into contact with each other even when the dimensional tolerance of the member is taken into consideration, so that the lid 50 is a type that rotates around the hinge 28 and closes. Even so, the volume of the gap G between the pouring cylinder 24 and the sealing protrusion 52 can be minimized. Therefore, it is possible to provide the pouring cap 1 in which the pouring outlet 24a and the lid 50 are less likely to be soiled due to the adhesion of the contents in the gap G while reducing the number of parts.

また、蓋体50が、キャップ本体20に対してねじ係合又は打栓係合されている場合では、蓋体50の閉塞時において、シール用突起52の外周面と注出筒24の内周面との最小距離を、部材の寸法公差等を考慮しても注出筒24とシール用突起52とが接触しないような距離とすることにより、ヒンジタイプの蓋体50と同様に、注出筒24とシール用突起52との隙間Gの容積を最小化することができる。よって、隙間G内の内容物の付着によって注出口24aや蓋体50が汚れにくい注出キャップ1を提供することができる。 When the lid 50 is screw-engaged or plugged with the cap body 20, the outer peripheral surface of the sealing protrusion 52 and the inner circumference of the pouring cylinder 24 when the lid 50 is closed. By setting the minimum distance to the surface so that the dispensing cylinder 24 and the sealing protrusion 52 do not come into contact with each other even when the dimensional tolerance of the member is taken into consideration, the dispensing is performed in the same manner as the hinge type lid 50. The volume of the gap G between the cylinder 24 and the sealing protrusion 52 can be minimized. Therefore, it is possible to provide the pouring cap 1 in which the pouring outlet 24a and the lid 50 are not easily soiled by the adhesion of the contents in the gap G.

また、本実施形態では、シール用突起52の下端部52aに、シール用突起52よりも縮径した突部54を設けた。これによって、蓋体50の閉塞時に突部54が注出筒24に干渉することなく注出筒24内に残存する内容物を内部空間M内に押し戻す。このため、注出筒24に残存する内容物を容易に回収することができる。また、蓋体50の閉塞時に突部54が注出口24aを貫通して内部空間M内に突出するため、弁体40が天面30Uに貼り付いても、突部54が弁体40を下方に押圧して貼り付きを解除することができる。 Further, in the present embodiment, the lower end portion 52a of the sealing protrusion 52 is provided with a protrusion 54 having a diameter smaller than that of the sealing protrusion 52. As a result, when the lid 50 is closed, the protrusion 54 pushes the contents remaining in the dispensing cylinder 24 back into the internal space M without interfering with the dispensing cylinder 24. Therefore, the contents remaining in the dispensing cylinder 24 can be easily recovered. Further, when the lid 50 is closed, the protrusion 54 penetrates the spout 24a and protrudes into the internal space M, so that even if the valve body 40 sticks to the top surface 30U, the protrusion 54 lowers the valve body 40. You can release the sticking by pressing on.

また、本実施形態では、弁体40が球形状を有し、保持筒30の内部空間Mにおける天面30Uが弁体40の形状に対応した球弧面であるように構成した。これによって、注出筒24内からバックサクション効果によって容器10の方向へ戻された内容物が球弧面を有する天面30Uに沿って下方に流れ易くなる。従って、内容物の回収が容易となる。また、天面30Uに内容物が残存しても、内容物の注出時に弁体40に押圧されリブ30Rの間から押し出されて注出口24aへと導くことができる。 Further, in the present embodiment, the valve body 40 has a spherical shape, and the top surface 30U in the internal space M of the holding cylinder 30 is configured to be a spherical arc surface corresponding to the shape of the valve body 40. As a result, the contents returned from the inside of the pouring cylinder 24 toward the container 10 by the back suction effect can easily flow downward along the top surface 30U having the spherical arc surface. Therefore, the contents can be easily collected. Further, even if the contents remain on the top surface 30U, they can be pushed by the valve body 40 at the time of pouring the contents and pushed out from between the ribs 30R to lead to the spout 24a.

また、本実施形態では、保持筒30が、下方に向けて縮径した後に拡径する屈曲部32を有するように構成した。これによって、注出筒24とシール用突起52との隙間Gの容積を最小化するために注出口24aを小さく形成しても、保持筒30をキャップ本体20と一体形成したまま、開口34側から弁体40を内部空間M内に容易に入れることができる。 Further, in the present embodiment, the holding cylinder 30 is configured to have a bent portion 32 whose diameter is reduced and then expanded downward. As a result, even if the pouring outlet 24a is made small in order to minimize the volume of the gap G between the pouring cylinder 24 and the sealing protrusion 52, the holding cylinder 30 remains integrally formed with the cap body 20 on the opening 34 side. The valve body 40 can be easily put into the internal space M.

本実施形態では、保持筒30をキャップ本体20と一体に形成する構成とすることにより、特に、頂壁部21と一体に形成される保持筒30の剛性を高めることができる。これにより、容器10の胴部が強くスクイズされる等して内容物が高い圧力で注出された場合であっても、保持筒30の変形を抑制して、弁体40を確実に作動(開閉動作)させることができる。したがって、この注出キャップ1が装着された容器10から内容物を確実に注出させることができるとともに、内容物の注出後に容器10の内層体13内に外気が導入されることを確実に防止することができる。 In the present embodiment, the rigidity of the holding cylinder 30 integrally formed with the top wall portion 21 can be particularly increased by forming the holding cylinder 30 integrally with the cap body 20. As a result, even when the contents are poured out at a high pressure such as when the body of the container 10 is strongly squeezed, the deformation of the holding cylinder 30 is suppressed and the valve body 40 is reliably operated (). It can be opened and closed). Therefore, the contents can be reliably poured out from the container 10 to which the pouring cap 1 is attached, and the outside air is surely introduced into the inner layer 13 of the container 10 after the contents are poured out. Can be prevented.
