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 a mouth portion of a container and that dispenses the content liquid contained in the container from a 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 dispensing cap is attached to the mouth of containers that contain cosmetic liquids such as lotions, shampoos and rinses, liquid soaps, and food seasonings to make it easy to dispense appropriate amounts of liquids. 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を備え、キャップ本体の内側に組み付けられるホルダと、円筒部の内面に設けられたストッパ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, the content liquid is spouted as a spout cap attached to the mouth portion of a delamination container in which the inner layer body containing the content liquid is peelably laminated inside the outer layer body. A cap body having a top wall portion integrally provided on the top surface and a mounting tube portion integrally provided on the outer periphery of the top wall portion and attached to the outer periphery of the mouth portion by screwing or the like; A holder that is assembled to the inside of the cap body, and includes a holding cylinder having a cylindrical portion that is continuous with the outlet tube and a reduced diameter cylindrical portion that is continuous with the lower end of the cylindrical portion and that gradually decreases in diameter toward the lower side; And a ball valve that is disposed inside the holding cylinder so as to be movable between a stopper projection provided on the inner surface of the cylinder and a reduced diameter cylindrical portion, and opens and closes an opening provided at the lower end of the reduced diameter cylindrical portion. Are listed.

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 delamination container equipped with such a pouring cap, the body portion of the outer layer body can be squeezed (pressed) to discharge the content liquid from the pouring cylinder, and after releasing the squeeze, the ball valve By closing the opening of the holding cylinder, that is, the dispensing cylinder while introducing the outside air between the outer layer body and the inner layer body through the outside air introduction hole provided in the outer layer body, the body portion is restored while the inner layer body is deformed and reduced in volume. Can be made. Thereby, it replaces with the poured out content liquid and prevents the outside air from being sucked into the inner layer body, thereby suppressing the contact of the content liquid with the outside air and maintaining its quality.

本発明の一実施の形態に係る注出キャップを容器の口部に装着した状態で示す断面図である。It is sectional drawing shown in the state which mounted | wore the mouth part of the container with the extraction | pouring cap which concerns on one embodiment of this invention. 図１におけるＡ−Ａ線に沿う断面図である。It is sectional drawing which follows the AA line in FIG.

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。   Hereinafter, the present invention will be described in more detail with reference to the drawings.

図１に示す本発明の一実施の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液を収容する容器１０の口部１１に装着されて容器１０に収容された内容液を外部に注出するものである。   A dispensing cap 1 according to an embodiment of the present invention shown in FIG. 1 is provided in a mouth portion 11 of a container 10 that contains cosmetics such as lotion, shampoos and rinses, liquid soap or food seasonings. The content liquid that is mounted and accommodated in the container 10 is 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に形成されている。この場合、口部１１には外層体１２と内層体１３との間に連通する外気導入孔１４が設けられ、容器１０の胴部（不図示）がスクイズ（押圧）されると内容液が注出キャップ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、外気導入孔１４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、注出された内容液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、内容液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 in a delamination container having an outer layer body 12 and an inner layer body 13 that is laminated inside the outer layer body 12 so as to be peelable from the outer layer body 12. In this case, the mouth portion 11 is provided with an outside air introduction hole 14 communicating between the outer layer body 12 and the inner layer body 13, and the content liquid is poured when the body portion (not shown) of the container 10 is squeezed (pressed). On the other hand, after the squeeze of the body portion is released, outside air is introduced between the outer layer body 12 and the inner layer body 13 through the outside air introduction hole 14 to reduce the volume of the inner layer body 13 after being released from the outlet cap 1. The trunk is restored. As a result, it is possible to prevent the outside air from being sucked into the inner layer body 13 by being replaced with the dispensed content liquid, to suppress the contact of the content liquid with the outside air, and to maintain its quality. .

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

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 a cylindrical shape having a top wall portion 21 formed in a substantially disc shape and a cylindrical mounting tube portion 22 provided integrally with 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 attached to the mouth portion 11 so as to abut the opening end of the mouth portion 11. In addition, as shown in the drawing, a seal cylinder 23 that is formed to have a smaller diameter than the mounting cylinder part 22 and is in liquid-tight contact with the inner peripheral surface of the mouth part 11 can be integrally provided on the lower surface of the top wall part 21. .

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。   An engagement protrusion 22 a is provided on the inner peripheral surface of the mounting cylinder portion 22 at the lower end side, and the engagement protrusion 22 a is provided on the outer peripheral surface of the mouth portion 11. The cap main body 20 is attached to the mouth portion 11 in a state where the cap body 20 is prevented from coming off. That is, the pouring cap 1 is configured such that the cap body 20 is attached to the mouth portion 11 by a stopper.

頂壁部２１の上面には内容液を外部に注出する注出口となる注出筒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。   On the top surface of the top wall portion 21, a pouring cylinder 24 is integrally provided as a pouring outlet for pouring the content liquid to the outside. The extraction cylinder 24 is formed in a shape that curves outward while gradually increasing in diameter upward from a connection portion with the top wall portion 21.

キャップ本体２０は、蓋体２５を一体に備えた構成とすることもできる。蓋体２５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２６を介してキャップ本体２０に一体に連結されている。蓋体２５は、その開口内周面に設けられた係止溝２５ａ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２５が閉じられると、注出筒２４が蓋体２５に覆われるとともに、蓋体２５の内面に一体に設けられた栓体２７が注出筒２４に嵌合して注出筒２４が栓体２７により閉塞される。   The cap body 20 may be configured to include the lid body 25 integrally. The lid body 25 is formed in a cylindrical shape having a substantially same diameter as the cap body 20, and is integrally connected to the cap body 20 via a hinge 26 on the outer peripheral surface thereof. The lid 25 is held in a closed state by an undercut engagement of a locking groove 25 a provided on the inner peripheral surface of the opening with a locking projection 21 a provided on the outer peripheral edge of the top wall portion 21. When the lid body 25 is closed, the dispensing cylinder 24 is covered with the lid body 25, and a plug body 27 provided integrally with the inner surface of the lid body 25 is fitted into the dispensing cylinder 24 so that the dispensing cylinder 24 is It is blocked by the plug body 27.

なお、蓋体２５はヒンジ２６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にねじ止めにより装着される構成とすることもできる。   The lid body 25 is not limited to a structure that is integrally connected to the cap body 20 via the hinge 26, and may be configured to be attached to the cap body 20 by screwing, for example.

保持筒３０は円筒部３１と縮径筒部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に連なる内容液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 reduced diameter cylindrical portion 32, and is formed in a cylindrical shape as a whole, and the inside thereof serves as a flow path for the content liquid continuous to the dispensing cylinder 24. The holding cylinder 30 is formed integrally with the cap body 20.

円筒部３１は注出筒２４の下端に一体に連ねて設けられ、この円筒部３１の下端（容器１０の内部側を向く端）に縮径筒部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、これに対して縮径筒部３２は下方に向けて徐々に内径が縮径するテーパ形状に形成されている。また、図示する場合では、縮径筒部３２の下端には円筒状の開口筒部３３が一体に設けられ、この開口筒部３３の内側が保持筒３０の開口３４つまり内容液の流入口を構成している。   The cylindrical portion 31 is provided integrally with the lower end of the dispensing tube 24, and the reduced diameter cylindrical portion 32 is provided integrally with the lower end of the cylindrical portion 31 (the end facing the inner side of the container 10). The cylindrical portion 31 is formed in a cylindrical shape having a substantially constant inner diameter, while the reduced diameter cylindrical portion 32 is formed in a tapered shape in which the inner diameter is gradually reduced downward. In the illustrated case, a cylindrical opening tube portion 33 is integrally provided at the lower end of the reduced diameter tube portion 32, and the inside of the opening tube portion 33 serves as an opening 34 of the holding tube 30, that is, an inflow port for content liquid. It is composed.

図２に示すように、保持筒３０の内周面には３本のリブ３５が一体に設けられている。これらのリブ３５は、それぞれ保持筒３０の軸方向に沿って延びるとともに周方向に等間隔に並んで放射状に配置されており、その内側を向く面は開口３４よりも径方向外側に位置するようになっている。   As shown in FIG. 2, three ribs 35 are integrally provided on the inner peripheral surface of the holding cylinder 30. These ribs 35 extend along the axial direction of the holding cylinder 30 and are arranged radially at equal intervals in the circumferential direction, and the inwardly facing surfaces are located radially outside of the openings 34. It has become.

また、図１からも解るように、それぞれのリブ３５の上端部分には円筒部３１の内周面から突出するストッパ突起３６が一体に設けられている。これらのストッパ突起３６は、それぞれリブ３５よりも径方向内側に向けて突出しており、縮径筒部３２との間に軸方向に沿って延びる凹んだ移動経路を区画形成している。   Further, as can be seen from FIG. 1, stopper protrusions 36 that protrude from the inner peripheral surface of the cylindrical portion 31 are integrally provided at the upper end portions of the respective ribs 35. Each of these stopper protrusions 36 protrudes radially inward from the rib 35, and defines a recessed movement path extending along the axial direction between the stopper protrusion 36 and the reduced diameter cylindrical portion 32.

なお、本実施の形態においては、ストッパ突起３６をリブ３５と一体に設けるようにしているが、これに限らず、ストッパ突起３６をリブ３５から離して設けることもできる。   In this embodiment, the stopper protrusion 36 is provided integrally with the rib 35. However, the present invention is not limited to this, and the stopper protrusion 36 may be provided separately from the rib 35.

弁体４０は鋼材や樹脂等により球状（ボール）に形成され、保持筒３０の内部に配置されている。弁体４０は各リブ３５に支持されて円筒部３１の内周面に対して間隔を空けて配置されており、これにより円筒部３１の内周面と弁体４０の外周面との間つまり各リブ３５の間には内容液の流路が確保されるようになっている。また、弁体４０の直径は開口筒部３３の内径およびストッパ突起３６の間隔よりも大きくなっている。これにより、弁体４０はストッパ突起３６と縮径筒部３２との間で、リブ３５に沿って軸方向に移動自在となっている。   The valve body 40 is formed into a spherical shape (ball) from steel, resin, or the like, and is disposed inside the holding cylinder 30. The valve body 40 is supported by the ribs 35 and is arranged at a distance from the inner peripheral surface of the cylindrical portion 31, whereby the valve body 40 is located between the inner peripheral surface of the cylindrical portion 31 and the outer peripheral surface of the valve body 40. A flow path for the content liquid is secured between the ribs 35. Further, the diameter of the valve body 40 is larger than the inner diameter of the opening cylinder portion 33 and the interval between the stopper protrusions 36. As a result, the valve body 40 is movable in the axial direction along the rib 35 between the stopper projection 36 and the reduced diameter cylindrical portion 32.

内容液を注出するために注出キャップ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が縮径筒部３２から離れる方向に移動して円筒部３１の内部に配置され、円筒部３１の内周面と弁体４０の外周面との間に内容液の流路が確保される。これにより、開口３４つまり注出筒２４が開かれ、容器１０に収容された内容液が開口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。一方、内容液の注出後、胴部のスクイズが解除されて容器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縮径筒部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の内部への外気の導入が阻止される。   When the barrel portion is squeezed while the container 10 is tilted so that the dispensing cap 1 is on the lower side in order to pour out the content liquid, the valve body 40 moves in a direction away from the reduced diameter cylindrical portion 32 and the cylindrical portion. The liquid passage of the content liquid is ensured between the inner peripheral surface of the cylindrical portion 31 and the outer peripheral surface of the valve body 40. As a result, the opening 34, that is, the dispensing cylinder 24 is opened, and the content liquid stored in the container 10 flows into the holding cylinder 30 from the opening 34, and between the inner peripheral surface of the cylindrical portion 31 and the outer peripheral surface of the valve body 40. It is poured out from the pouring cylinder 24 through the flow path. On the other hand, after the content liquid is poured out, when the squeeze of the body portion is released and the container 10 is returned to the upright posture in which the pouring cap 1 is on the upper side, the valve body 40 faces the inside of the holding cylinder 30 downward. To move and come into contact with the reduced diameter cylindrical portion 32. Thereby, the opening 34, that is, the dispensing cylinder 24 is closed by the valve body 40, and introduction of outside air from the dispensing cylinder 24 to the inside of the container 10 is prevented.

このような注出キャップ１においては、上記のように、保持筒３０はキャップ本体２０と一体に形成されている。   In such a pouring cap 1, the holding cylinder 30 is formed integrally with the cap body 20 as described above.

このように、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溶液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から内容液を確実に注出させることができるとともに、内容液の注出後に容器１０の内部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 this way, by adopting a configuration in which the holding cylinder 30 is formed integrally with the cap main body 20, in particular, the rigidity of the holding cylinder 30 formed integrally with the top wall portion 21 can be increased. Accordingly, even when the inner solution is poured out at a high pressure due to the squeeze of the body portion of the container 10 or the like, the deformation of the holding cylinder 30 is suppressed and the valve body 40 is reliably operated ( Open and close operation). Therefore, the content liquid can be surely poured out from the container 10 to which the pouring cap 1 is attached, and the outside air is reliably prevented from being introduced into the container 10 after the content liquid is poured out. Can do.

また、本実施の形態においては。弁体４０の保持筒３０の内部における移動ストローク量を弁体４０の直径よりも小さくするようにしている。このような設定とすることにより、保持筒３０の変形が弁体４０の移動に与える影響を低減して、弁体４０の作動をさらに安定させることができる。   In the present embodiment. The moving stroke amount of the valve body 40 inside the holding cylinder 30 is made smaller than the diameter of the valve body 40. With such a setting, the influence of the deformation of the holding cylinder 30 on the movement of the valve body 40 can be reduced, and the operation of the valve body 40 can be further stabilized.

また、弁体４０の保持筒３０の内部における移動ストローク量を弁体４０の直径よりも小さくすることにより、開口３４を通した容器１０の内部への外気の侵入を確実に防止することができる。   Further, by making the moving stroke amount of the valve body 40 inside the holding cylinder 30 smaller than the diameter of the valve body 40, it is possible to reliably prevent the outside air from entering the inside of the container 10 through the opening 34. .

表１に、本発明の注出キャップを積層剥離容器に構成された容器の口部に装着し、弁体として直径が３．７５ｍｍの樹脂製（ポリプロピレン製）のものを用い、この弁体の保持筒の内部における移動ストローク量を種々変更して、注出キャップが下方側となるように容器を４５度の角度で傾斜させて容器の胴部をスクイズして内容液を注出させた後、当該スクイズを解除したときに、開口を通した容器の内部への外気の侵入が弁体により阻止可能か否かを調べた実験結果を示す。   In Table 1, the pouring cap of the present invention is attached to the mouth portion of a container configured as a delamination container, and a valve body made of resin (polypropylene) having a diameter of 3.75 mm is used. After variously changing the moving stroke amount inside the holding cylinder, the container is inclined at an angle of 45 degrees so that the pouring cap is on the lower side, the container body is squeezed, and the content liquid is poured out The experimental result which investigated whether the penetration | invasion of the external air to the inside of the container through an opening could be blocked | prevented with a valve body when the said squeeze was cancelled | released is shown.

表１から、弁体の保持筒の内部における移動ストローク量を弁体の直径よりも小さくすれば、開口を通した容器の内部への外気の侵入が確実に防止されることが解る。   From Table 1, it can be seen that if the moving stroke amount inside the holding cylinder of the valve body is made smaller than the diameter of the valve body, the intrusion of outside air into the container through the opening is surely prevented.

さらに、弁体４０の保持筒３０の内部における移動ストローク量を弁体４０の直径よりも小さくすることにより、保持筒３０の、頂壁部２１の下面から容器１０の内部に向けた突出長さを短くすることができる。これにより、注出キャップ１が下方側となるように容器１０を傾斜させたときに、開口３４に流入することなく保持筒３０の外周面と口部１１の内周面との間に溜まる内容液の量を低減して、容器１０から注出されずに容器１０の内部に残る内容液の残量を低減することができる。   Further, by making the moving stroke amount of the valve body 40 inside the holding cylinder 30 smaller than the diameter of the valve body 40, the protruding length of the holding cylinder 30 from the lower surface of the top wall portion 21 toward the inside of the container 10. Can be shortened. As a result, when the container 10 is tilted so that the dispensing cap 1 is on the lower side, the content accumulated between the outer peripheral surface of the holding cylinder 30 and the inner peripheral surface of the mouth portion 11 without flowing into the opening 34. By reducing the amount of the liquid, the remaining amount of the content liquid remaining inside the container 10 without being poured out of the container 10 can be reduced.

さらに、保持筒３０をキャップ本体２０と一体に形成することにより、保持筒３０をホルダ等とともにキャップ本体２０と別体に形成した場合に比べて部品点数を削減して、この注出キャップ１のコストを低減することができる。   Furthermore, by forming the holding cylinder 30 integrally with the cap body 20, the number of parts can be reduced compared with the case where the holding cylinder 30 is formed separately from the cap body 20 together with a holder or the like. Cost can be reduced.

図示する場合では、保持筒３０はキャップ本体２０および蓋体２５とともに樹脂材の射出成形により一体に形成するようにしている。これにより、キャップ本体２０と保持筒３０とを一体に形成した注出キャップ１を容易に形成することができる。特に、本実施の形態のように、注出キャップ１を、ねじ止めではなく、容器１０の口部１１に打栓により装着するようにした構成では、装着筒部２２の内周面に雌ねじではなく被係合突起２２ａを設ければよいので、樹脂材料の射出成形に無理抜きを行うことなく、当該射出成形により注出キャップ１を容易に形成することができる。   In the illustrated case, the holding cylinder 30 is formed integrally with the cap body 20 and the lid body 25 by injection molding of a resin material. Thereby, the extraction | pouring cap 1 which formed the cap main body 20 and the holding cylinder 30 integrally can be formed easily. In particular, in the configuration in which the dispensing cap 1 is attached to the mouth portion 11 of the container 10 not by screwing, as in the present embodiment, by a female screw on the inner peripheral surface of the mounting cylinder portion 22. Therefore, the spout cap 1 can be easily formed by injection molding without forcing the resin material to be injection molded.

本発明は前記実施の形態に限定されるものではなく、その要旨を逸脱しない範囲で種々変更可能であることはいうまでもない。   It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

例えば、前記実施の形態においては、本発明の注出キャップ１を積層剥離容器に構成された容器１０の口部１１に装着するようにしているが、これに限らず、例えば外層体と内層体とを有する二重容器など、他の構成の容器の口部に装着することもできる。   For example, in the said embodiment, although the pouring cap 1 of this invention is mounted | worn with the opening part 11 of the container 10 comprised by the lamination peeling container, it is not restricted to this, For example, an outer layer body and an inner layer body It can also be attached to the mouth of a container having another configuration, such as a double container having

また、リブ３５は３本に限らず、３本以上設けられていればよい。   Further, the number of ribs 35 is not limited to three, and three or more ribs 35 may be provided.

さらに、弁体４０は球状に限らず、保持筒３０の内部に軸方向に移動自在に収容されて開口３４を開閉することができるものであれば、種々の形状とすることができる。   Further, the valve body 40 is not limited to a spherical shape, and may be various shapes as long as it is accommodated in the holding cylinder 30 so as to be movable in the axial direction and can open and close the opening 34.

さらに、注出キャップ１は、容器１０の口部１１に打栓により装着される構成に限らず、ねじ止めにより装着される構成とすることもできる。   Furthermore, the pouring cap 1 is not limited to a configuration in which the pouring cap 1 is mounted on the mouth portion 11 of the container 10 by plugging, but may be configured to be mounted by screwing.
