Description

本発明は、内容液を収容する容器本体の口部に装着されるとともに内容液を注出させる注出筒を備える注出キャップ、及び注出キャップを容器本体に装着した注出容器に関するものである。   The present invention relates to a pouring cap that is attached to a mouth portion of a container main body that contains the content liquid and includes a pouring cylinder for pouring the content liquid, and a pouring container in which the pouring cap is attached to the container main body. is there.

従来、シャンプーやリンス或いは液体石鹸、また各種の食品調味料や薬品などを内容液として収容する容器本体は、例えば特許文献１に示されているように、その口部に注出キャップを装着して使用されている。このような注出キャップには、筒状をなしその先端から内容液を注出させる注出筒が設けられていて、これにより容器本体の収容空間に収めた内容液を、飛び散りなく適量で注出させることができる。   Conventionally, container bodies that contain shampoos, rinses, liquid soaps, various food seasonings, chemicals, and the like as content liquids, for example, as shown in Patent Document 1, are equipped with a pouring cap at the mouth. Have been used. Such a pouring cap is provided with a pouring cylinder that is cylindrical and pours the content liquid from its tip, so that an appropriate amount of the content liquid stored in the storage space of the container body can be poured without scattering. Can be issued.

ところでこのような注出キャップは、注出が終了しても、粘性等の影響によって注出筒の内側に内容液が残ってしまうことがある。そしてこのような注出キャップには、注出筒の内面に当接するシール部を設けた蓋体が設けられているところ、内容液が残った状態で蓋体を閉めると、シール部によって内容液が押し出されて注出筒の外側に溢れてしまうことになる。このため特許文献１の注出キャップには、注出筒の内容液を容器本体に引き戻すサックバック機能を作用させるべく、上部開口が注出筒に連通するとともに下部開口が収容空間に連通する内部筒と、内部筒の内側に配され、内部筒の軸線に沿って移動可能な移動弁とを設けている。このような注出キャップによれば、内容液を注出させるにあたり、容器本体を傾倒姿勢に変位させることによって注出筒側に移動していた移動弁は、注出終了後に容器本体を正立姿勢に変位させることによって収容空間側に移動するため、注出筒に残った内容液を内部筒に向けて引き戻すことができる。   By the way, even if such a pouring cap ends pouring, the content liquid may remain inside the pouring cylinder due to the influence of viscosity or the like. Such a pouring cap is provided with a lid provided with a seal portion that comes into contact with the inner surface of the dispensing cylinder. When the lid is closed with the content liquid remaining, the content liquid is removed by the seal portion. Is pushed out and overflows to the outside of the dispensing cylinder. For this reason, in the pouring cap of Patent Document 1, the upper opening communicates with the pouring cylinder and the lower opening communicates with the accommodation space in order to act a suck back function of drawing back the liquid content of the dispensing cylinder to the container body. A cylinder and a movement valve that is arranged inside the inner cylinder and is movable along the axis of the inner cylinder are provided. According to such a pouring cap, the moving valve that has been moved to the pouring cylinder side by displacing the container main body to the tilted posture when pouring the content liquid, erects the container main body upright after the pouring is completed. Since it moves to the accommodation space side by displacing to the posture, the content liquid remaining in the dispensing cylinder can be pulled back toward the inner cylinder.

一方このような注出キャップには、例えば注出時の流れの安定性や液切れ性を考慮して、特許文献１に示す如き大径の注出筒を使用ことがある。しかし、注出筒が大きくなるにつれてその内側に残る内容液の量も多くなるため、単に内部筒と移動弁を設けても、蓋体を閉めた際の内容液の溢れが解消できないことがあった。   On the other hand, for such a pouring cap, a large-diameter pouring tube as shown in Patent Document 1 may be used in consideration of, for example, the stability of the flow at the time of pouring and the ability to run out of liquid. However, since the amount of content liquid remaining inside the dispensing cylinder increases, the overflow of the content liquid when the lid is closed may not be eliminated even if the internal cylinder and the movement valve are simply provided. It was.

In this embodiment, the inner diameter D1 of the dispensing cylinder 4d (the inner diameter of the lower end opening 4f) is about 2.5 mm, and the inner diameter D2 of the inner cylinder 5e (the center of the moving valve 7 in a state where the moving valve 7 has moved to the upper position). The inner diameter) is about 3.5 mm.

このような構成になる注出容器１においては、外容器２ｂを押圧することによって内容器２ａと外容器２ｂとの間の空間に存在する空気が加圧され、これによって収容空間Ｓの圧力が高まるため、収容空間Ｓの内容物は、弁体６ｂを天壁５ａから離反させつつ、連通口５ｂから連結片６ｃの周囲の隙間を通って内部空間Ｎに流れ込み、注出筒４ｄの内側を通って注出される。なお、内容器２ａと外容器２ｂとの間の空間は、通気口２ｅ、縁部切り欠き５ｋ、及び上部切り欠き５ｊを介して外気導入口４ｅに連通しているが、縁部切り欠き５ｋの内側に形成される空間は狭いため、内容器２ａと外容器２ｂの間に存在する空気が加圧されても、外界へは殆ど逃げ出すことがない。なお、移動弁７は、内容物を注出させるべく容器本体２を傾倒姿勢に変位させた状態において、自重や内部筒５ｅの下方側の開口から流入する内容物によって、図１に仮想線で示した上位置に移動している。   In the pouring container 1 having such a configuration, the air existing in the space between the inner container 2a and the outer container 2b is pressurized by pressing the outer container 2b, whereby the pressure in the accommodation space S is increased. Therefore, the contents of the storage space S flow into the internal space N from the communication port 5b through the gap around the connecting piece 6c while separating the valve body 6b from the top wall 5a, and the inside of the extraction cylinder 4d. Poured out through. The space between the inner container 2a and the outer container 2b communicates with the outside air inlet 4e through the vent 2e, the edge notch 5k, and the upper notch 5j, but the edge notch 5k. Since the space formed inside is narrow, even if the air existing between the inner container 2a and the outer container 2b is pressurized, it hardly escapes to the outside. Note that the moving valve 7 is shown in phantom lines in FIG. 1 depending on its own weight or the contents flowing in from the opening on the lower side of the inner cylinder 5e in a state where the container body 2 is displaced in a tilted posture so as to dispense the contents. It has moved to the indicated upper position.

その後、外容器２ｂへの押圧を解除して容器本体２を元の正立姿勢に変位させると、収容空間Ｓの圧力が元の状態に戻って弁体６ｂが天壁５ａの上面に着座し、連通口５ｂは閉鎖される一方で、上部開口５ｄの一部は解放したままとなる。また移動弁７は、それ自身の自重や収容空間Ｓ内の圧力低下によって、図１に実線で示した下位置に移動する。これにより、内部筒５ｅの上方内側には、行程容積Ｂ１に相当するスペースが形成されることになるため、このスペースに相当する分の内容液が内部空間Ｎに引き戻され、その結果、注出筒４ｄの内容液は内部筒５ｅ側へ引き戻される。ここで、内容積Ａ１は行程容積Ｂ１よりも小さいため、注出筒４ｄに内容液が溜まることがない。このため、蓋体８を閉めた際に生じていた注出筒４ｄからの内容液の溢れ出しを防止することができる。なお、外容器２ｂの復元に伴って内容器２ａと外容器２ｂとの間の空間が減圧状態になると、外気導入口４ｅから外気が取り込まれ、縁部切り欠き５ｋと上部切り欠き５ｊを通して通気口２ｅから外気が導入される。これにより、内容器２ａを減容変形させたまま、外容器２ｂのみを復元させることができる。   Thereafter, when the pressure on the outer container 2b is released and the container body 2 is displaced to the original upright posture, the pressure in the accommodation space S returns to the original state, and the valve body 6b is seated on the upper surface of the top wall 5a. The communication port 5b is closed, while a part of the upper opening 5d remains open. Further, the moving valve 7 moves to a lower position shown by a solid line in FIG. 1 due to its own weight or a pressure drop in the accommodation space S. As a result, a space corresponding to the stroke volume B1 is formed on the upper inner side of the inner cylinder 5e, so that the content liquid corresponding to this space is drawn back to the inner space N. The liquid in the cylinder 4d is drawn back to the inner cylinder 5e side. Here, since the internal volume A1 is smaller than the stroke volume B1, the content liquid does not accumulate in the dispensing cylinder 4d. For this reason, it is possible to prevent the overflow of the content liquid from the dispensing cylinder 4d that has occurred when the lid 8 is closed. When the space between the inner container 2a and the outer container 2b is decompressed as the outer container 2b is restored, the outside air is taken in from the outer air introduction port 4e and is ventilated through the edge notch 5k and the upper notch 5j. Outside air is introduced from the mouth 2e. Thereby, it is possible to restore only the outer container 2b while reducing the volume of the inner container 2a.

次に、図３、図４を参照しながら、本発明に従う注出キャップ、及び注出容器の第二実施形態について説明する。符号１１で示した第二実施形態の注出容器は、容器本体１２、及び注出キャップ１３を備えている。また注出キャップ１３は、キャップ本体１４、移動弁１７、及び蓋体１８で構成されている。   Next, a second embodiment of the dispensing cap and the dispensing container according to the present invention will be described with reference to FIGS. The dispensing container of the second embodiment indicated by reference numeral 11 includes a container body 12 and a dispensing cap 13. The dispensing cap 13 is composed of a cap body 14, a moving valve 17, and a lid 18.

本実施形態の容器本体１２は、内容液の収容空間Ｓを有する内容器１２ａと、内容器１２ａを内側に収める外容器１２ｂとを備えている。   The container body 12 of the present embodiment includes an inner container 12a having a content liquid storage space S and an outer container 12b for accommodating the inner container 12a inside.

本実施形態の内容器１２ａは、前述の内容器２ａと同様に、薄肉の合成樹脂製であって、減容変形可能に設けられている。   The inner container 12a of the present embodiment is made of a thin synthetic resin, and is provided so as to be capable of volume reduction deformation, like the inner container 2a described above.

また外容器１２ｂは、円筒状になる口部１２ｃを備えていて、口部１２ｃの外周面には、径方向外側に向けて突出する突起１２ｄが設けられている。口部１２ｃの下部には、図示は省略するが有底筒状の外容器本体が設けられていて、その底部には、スリット状の間隙が設けられている。なお、本実施形態の外容器１２ｂも合成樹脂で形成されていて、外容器本体は可撓性を有している。   The outer container 12b includes a mouth portion 12c that is cylindrical, and a protrusion 12d that protrudes radially outward is provided on the outer peripheral surface of the mouth portion 12c. Although not shown, a bottomed cylindrical outer container main body is provided at the bottom of the mouth portion 12c, and a slit-like gap is provided at the bottom. In addition, the outer container 12b of this embodiment is also formed with the synthetic resin, and the outer container main body has flexibility.

キャップ本体１４は、本実施形態では合成樹脂で形成されていて、口部１２ｃを取り囲むとともに突起１２ｄに係止される外周壁１４ａと、外周壁１４ａの上方を覆って外周壁１４ａの上端部に連結する頂壁１４ｂとを備えている。また頂壁１４ｂには、上方に向けて縮径するように延在する傾斜部１４ｃが設けられていて、傾斜部１４ｃには、筒状をなし、上方に向けて突出するとともに先端部を径方向外側に向けて湾曲させてリップを形成した注出筒１４ｄが一体に連結している。また注出筒１４ｄの下方には、円筒状をなし、収容空間Ｓに通じる下部開口１４ｅと、注出筒１４ｄに通じる上部開口１４ｆとを備える内部筒１４ｇが、注出筒１４ｄに連続するようにして傾斜部１４ｃに一体に連結している。ここで内部筒１４ｇの内周面には、上下方向に延在するとともに周方向に間隔をあけて設けられる複数の縦リブ１４ｈが設けられていて、縦リブ１４ｈの上端には、注出筒１４ｄに向かって内部筒１４ｇの軸線Ｏに近づく向きに傾いて突出する突起１４ｋが設けられている。なお、「注出筒に向かって内部筒の軸線に近づく向きに傾いて突出する」とは、図３に示すように湾曲状に傾いて突出する状態だけでなく、直線状に傾いて突出する状態も含むものである。また内部筒１４ｇの下部には、収容空間Ｓに向かって縮径する縮径部１４ｍが設けられている。なお、図示は省略するが、縮径部１４ｍにも、前述の縮径部５ｆと同様の浅い溝を設けてもよい。   The cap body 14 is formed of a synthetic resin in this embodiment, and surrounds the mouth portion 12c and is locked to the protrusion 12d. The cap body 14 covers the upper portion of the outer peripheral wall 14a and the upper end portion of the outer peripheral wall 14a. And a top wall 14b to be connected. The top wall 14b is provided with an inclined portion 14c extending so as to reduce the diameter upward. The inclined portion 14c has a cylindrical shape, protrudes upward, and has a tip portion with a diameter. A pour cylinder 14d that is curved outward in the direction to form a lip is integrally connected. Also, below the dispensing cylinder 14d, an inner cylinder 14g having a cylindrical shape and having a lower opening 14e leading to the accommodation space S and an upper opening 14f communicating to the dispensing cylinder 14d is continuous with the dispensing cylinder 14d. Thus, it is integrally connected to the inclined portion 14c. Here, the inner peripheral surface of the inner cylinder 14g is provided with a plurality of vertical ribs 14h that extend in the vertical direction and are provided at intervals in the circumferential direction. Protrusions 14k that are inclined and project toward the axis O of the inner cylinder 14g toward 14d are provided. Note that “projecting in an inclined direction toward the axis of the inner cylinder toward the dispensing cylinder” means not only a state of projecting in a curved form as shown in FIG. 3 but also projecting in a linear form. It also includes the state. Further, a reduced diameter portion 14m that decreases in diameter toward the accommodation space S is provided at the lower portion of the inner cylinder 14g. In addition, although illustration is abbreviate | omitted, you may provide the shallow groove | channel similar to the above-mentioned diameter reducing part 5f also in the diameter reducing part 14m.

移動弁１７は、前述の移動弁７と同様に球状をなすものであり、内部筒１４ｇ内に配置されていて、内部筒１４ｇの軸線Ｏに沿って移動可能に設けられている。これにより移動弁１７は、容器本体１２を傾倒姿勢に変位させると、図３において仮想線で示したように、突起１４ｋに当接する上位置まで移動し、また容器本体１２を正立姿勢に変位させると、図３において実線で示したように、縮径部１４ｍに着座する下位置まで移動する。   The movement valve 17 has a spherical shape similar to the movement valve 7 described above, is disposed in the inner cylinder 14g, and is provided so as to be movable along the axis O of the inner cylinder 14g. Accordingly, when the container main body 12 is displaced to the tilted posture, the movement valve 17 moves to the upper position where it abuts against the protrusion 14k as shown by the phantom line in FIG. 3, and the container main body 12 is displaced to the upright posture. If it does, as shown by the continuous line in FIG. 3, it will move to the lower position seated on the reduced diameter part 14m.

蓋体１８は、頂壁４ｃの上方に位置する蓋体頂壁１８ａと、蓋体頂壁１８ａに一体に連結する蓋体外周壁１８ｂとを備えている。また蓋体頂壁１８ａの下面には、注出筒１４ｄの内側に挿入されるとともに注出筒１４ｄの内面に当接するシール筒１８ｃが設けられていて、更にシール筒１８ｃの径方向内側には、円柱状をなす棒状部１８ｄが設けられている。ここで棒状部１８ｄは、その先端が、蓋体１８を閉めた際に突起１４ｋよりも下方に位置するように設けられている。これにより、蓋体１８を閉めた状態で容器本体１２を傾倒姿勢に変位させたままにしても、移動弁１７は突起１４ｋに接触しないため、付着した内容液が乾くことによって移動弁１７が突起１４ｋに固着されて移動できなくなる不具合が防止できる。また蓋体外周壁１８ｂの外周面には、キャップ本体１４の外周壁１４ａに一体に連結するヒンジ部１８ｅが設けられている。   The lid 18 includes a lid top wall 18a located above the top wall 4c, and a lid outer peripheral wall 18b that is integrally connected to the lid top wall 18a. Further, a seal cylinder 18c is provided on the lower surface of the lid top wall 18a so as to be inserted inside the extraction cylinder 14d and abutted against the inner surface of the extraction cylinder 14d. A rod-shaped portion 18d having a cylindrical shape is provided. Here, the rod-shaped portion 18d is provided such that the tip thereof is positioned below the protrusion 14k when the lid 18 is closed. As a result, even if the container body 12 remains displaced in the tilted position with the lid 18 closed, the moving valve 17 does not come into contact with the protrusion 14k. It is possible to prevent a problem that it is fixed to 14k and cannot move. Further, a hinge portion 18e that is integrally connected to the outer peripheral wall 14a of the cap body 14 is provided on the outer peripheral surface of the lid outer peripheral wall 18b.

本実施形態において、注出筒１４ｄの内容積Ａ２は、図４においてハッチングを付して示すように、仮想線で示す上位置に移動した移動弁１７及び突起１４ｋの上面から注出筒１４ｄの上端開口１４ｐに至る空間の容積をいう。また、内部筒１４ｇの行程容積Ｂ２は、図４においてハッチングを付して示すように、内部筒１４ｇの内側における移動弁７の上位置での中心から下位置での中心に至る空間の容積をいう。ここで内容積Ａ２は、行程容積Ｂ２よりも小さくなくなるように設定されていて、本実施形態においては、内容積Ａ２は約０．１１ｃｍ３であり、行程容積Ｂ２は約０．１２ｃｍ３である。また、注出筒１４ｄと内部筒１４ｇの内径も、２〜７ｍｍに設定することが好ましく、本実施形態では、注出筒１４ｄの内径Ｄ３（移動弁１７が上位置に移動した状態における移動弁１７の上端での内径）は約６ｍｍであり、内部筒１４ｇの内径Ｄ４（移動弁７が上位置に移動した状態における移動弁７の中心での内径）は約４ｍｍである。 In the present embodiment, the inner volume A2 of the dispensing cylinder 14d is shown by hatching in FIG. 4 from the upper surface of the moving valve 17 and the projection 14k moved to the upper position indicated by the phantom line. The volume of the space reaching the upper end opening 14p. Further, the stroke volume B2 of the inner cylinder 14g is the volume of the space from the center at the upper position of the moving valve 7 to the center at the lower position inside the inner cylinder 14g, as shown by hatching in FIG. Say. Here internal volume A2 is preset to eliminate smaller than the stroke volume B2, in the present embodiment, the internal volume A2 is about 0.11 cm 3, the stroke volume B2 is about 0.12 cm 3 . Further, it is preferable that the inner diameters of the extraction cylinder 14d and the inner cylinder 14g are also set to 2 to 7 mm. In this embodiment, the inner diameter D3 of the extraction cylinder 14d (the movement valve in a state where the movement valve 17 is moved to the upper position). The inner diameter D4 of the inner cylinder 14g (the inner diameter at the center of the moving valve 7 when the moving valve 7 is moved to the upper position) is about 4 mm.

本実施形態の注出容器１１にあっても、前述の注出容器１１と同様にして内容液を注出することができる。また、内容積Ａ２は行程容積Ｂ２よりも小さいため、注出筒１４ｄに内容液が溜まったままになることがなく、蓋体１８を閉めても注出筒１４ｄから内容液が溢れてしまうことがない。   Even in the dispensing container 11 of the present embodiment, the content liquid can be poured out in the same manner as the above-described dispensing container 11. Further, since the internal volume A2 is smaller than the stroke volume B2, the content liquid does not remain in the extraction cylinder 14d, and the content liquid overflows from the extraction cylinder 14d even when the lid 18 is closed. There is no.
