【発明の属する技術分野】
本発明は、バッグインボックス用内袋等の容器のスパウトに装着される注出口付きキャップに関するものである。更に詳しくは、容器内の液体を注出させる際に、注出量の切り替えが可能な注出口付きキャップに関するものである。
【０００２】
バッグインボックス用内袋等の容器のスパウトに装着される注出口付きキャップは、注出口の内側を塞いでいるスパウトの先端部（開口部）とこれに内接するキャップの封止部内面の内、封止部の内面を注出口の内側より離し、注出口を開栓状態にしてから、容器内の液体を注出させていた。注出口の内側を塞いでいる封止部の内面を注出口より離す方法としては、封止部の上面に取り付けられたタブを引っ張る方法や、封止部の上面に付着された突起部を傾ける方法等がある。
【０００３】
そして、バッグインボックス用内袋等の容器から内容物の液体を注出させる際、一度に多量の内容物を注出させる場合には、注出口からの注出量が多い方法が好ましく、少量の内容物しか注出しない場合には、注出口からの注出量が少ない方法が好ましい。
【０００４】
しかし、上記したそれぞれの方法では、内容物の液体を注出する際、注出量を調整することが困難であった。即ち、封止部の上面に取り付けられたタブを引っ張る場合には、封止部の上面が湾曲して凹部を形成しているため、タブを引っ張ると、リング状タブが伸びるので力加減が難しく、常に十分に引っ張られた状態になってしまい、注出量を調整することが出来ず、注出量が一定になってしまう。又、封止部の上面に付着された突起部を傾ける場合にも、突起部が短く、又、封止部のほぼ中央部に付着しているため、突起部を傾けると常に十分傾けられた状態になってしまい、注出量を調整することが出来ず、注出量が一定になってしまう。
【０００５】
【発明が解決しようとする課題】
本発明は、容器内の液体を注出するときに、注出量を容易に調整することができる注出口付きキャップを提供しようとするものである。
そして、バッグインボックス用内袋等の容器から一度に多量の液体を注出する時でも、少量の液体しか注出しない時でも、どちらでも容易に注出することができるようにしようとするものである。
【０００６】
本発明は、上記課題を解決するために、注出口付きキャップの封止部の上面に取り付けられたタブを引っ張る方法と、封止部の上面に付着された突起部を傾ける方法を併用する方法を見出した。即ち、スパウトなどの先端開口部に内接し、注出口（２）の内側（２１）を塞いでいる封止部（３）の上面（３１）に突起部（４）が付着し、しかも、該突起部（４）の先端（４１）にリング状タブ（５）が取り付けられている。好ましくは、封止部（３）に付着している突起部（４）が、封止部（３）の中央部よりも注出口（２）側に付着している。更に好ましくは、封止部（３）に付着している突起部（４）の根元部（４２）が、注出口（２）側に向かって太くなっている。
【０００７】
本発明の流出量切り替え可能な注出口付きキャップを取り付ける容器としては、特に限定されるものではないが、プラスチックフィルムから製袋された袋に孔が開けられ、その孔に開口部を有するスパウトが熱融着等により取り付けられた容器、例えば、バッグインボックス用内袋等が好適である。しかも、本発明の注出口付きキャップが装着されるバッグインボックス用内袋等の容器の大きさとしては、５乃至２０リットル入りが好適である。
【０００８】
本発明の流出量切り替え可能な注出口付きキャップを構成する材質としては、特に限定されるものではなく、従来一般にキャップに使用されている合成樹脂を挙げることができる。特に、本発明の注出口付きキャップは、封止部を変形させて開栓させる機構であることから、封止部は柔軟な合成樹脂、例えば、熱可塑性エラストマー等が好適である。又、突起部を傾けて封止部を変形させる機構であることから、突起部は封止部より硬度の高い合成樹脂からなるものが好ましい。即ち、キャップを構成する合成樹脂は、必ずしも同一の合成樹脂である必要はなく、むしろ部材によってそれぞれ好適な合成樹脂を用いるのが好ましい。
【０００９】
以下、図面を用いて本発明の流出量切り替え可能な注出口付きキャップを詳細に説明する。
尚、本発明の注出口付きキャップは、図面に示された形状のものに限定されるものでないことは、当然である。
図１は、本発明の注出口付きキャップが容器のスパウトに装着された状態を示す概略断面図である。
図２は、本発明の注出口付きキャップの概略平面図である。
図３は、本発明の注出口付きキャップの突起部を傾けて、容器内の液体を注出する時の状態を示す概略断面図である。
図４は、本発明の注出口付きキャップのリング状タブを引っ張って、容器内の液体を注出する時の状態を示す概略断面図である。
【００１０】
まず、本発明の流出量切り替え可能な注出口付きキャップ（１）を装着する容器には、先端開口部を有するスパウト（８）が取り付けられている。そして、本発明の注出口付きキャップ（１）は、通常の状態では図１に示す如く、スパウト（８）の先端部（８１）と、これに内接する注出口付きキャップ（１）の封止部（３）の内面（３２）とによって注出口（２）の内側（２１）が塞がれて、注出口は完全に密封状態になっている。即ち、本発明の注出口付キャップが容器に取り付けられたスパウトに装着されている時、封止部は内側に湾曲して凹状を形成しており、しかも、柔軟性を有しているので、湾曲した封止部の内面は注出口の内側に密着し、スパウトの先端部と共に注出口の内側を完全に塞ぐ状態になっている。尚、注出口の形状は、円形であっても、矩形であってもかまわない。
【００１１】
そして、封止部（３）の上面（３１）には、突起部（４）が付着している。
突起部（４）が封止部（３）の上面（３１）に付着している位置としては、封止部（３）の中央部より注出口（２）側に位置しているのが好ましい。突起部（４）の付着している位置が、封止部（３）の中央部より注出口（２）側と反対側であると、突起部（４）を傾けた際に、封止部（３）に注出口（２）を開栓させるような変形を起こさせることが困難である。又、突起部（４）の付着している位置が、注出口（２）に近くなると、注出量は少なくなる。そこで、突起部を付着させる位置は、突起部を傾けた際に所望の注出量になるように適宜決定されればよい。
尚、一般に、リング状タブを引っ張った際の注出量は多くなるので、突起部を傾けた際の注出量は少ないのが好ましい。
【００１２】
又、封止部（３）に付着させる突起部（４）は、該根元部（４２）が注出口（２）側に向かって太くなっているのが好ましい。突起部（４）の根元部（４２）が注出口（２）側に向かって太くなっていると、突起部（４）を傾けた際に、注出口（２）の内側を塞いでいる封止部（３）を変形させ、注出口（２）を開栓状態にし易い。
突起部（４）の根元部（４２）が注出口（２）側に向かって太くなっているとは、突起部（４）そのものが注出口（２）側に向かって太くなっているのは勿論、突起部（４）の底部に注出口（２）側に向かって突出するように盤状体を付着させたものや、突起部（４）の注出口（２）側の根元側面と突起部と注出口の間で該根元側面の封止部（３）の上面（３１）に接合するように角棒状体や三角板状体等を付着させたもの等を挙げることができる。
【００１３】
尚、突起部は、封止部を変形させるため、指先で傾けても湾曲しないような硬度を有しているのが好ましい。又、突起部の高さは、特に限定されるものではないが、指先で傾けることができ、しかも、封止部の湾曲した凹部の中に収まる高さが好ましい。突起部が封止部の湾曲した凹部より飛び出していると、見栄えが悪くなるばかりか、何かに触れて突起部が傾けられ、容器内の液体が漏れ出す危険性がある。
【００１４】
更に、突起部（４）の先端部（４１）には、リング状タブ（５）が付着している。
リング状タブ（５）が突起部（４）の先端部（４１）に付着していると、リング状タブ（５）を引っ張った時、突起部（４）を傾けた時よりも注出口（２）の内側を塞いでいる封止部（３）を大きく変形させて完全な開栓状態とし、多量の液体を注出することができる。
【００１５】
又、タブがリング状になっていると、指先をそのリングに差し込んで容易に引っ張ることができる。しかも、タブがリング状になっていると、引っ張ったタブをキャップの周囲縁部（７）の引掛部（７１）に引っ掛けて止めておくこともできる。
尚、リング状とは、必ずしも円形である必要はなく、三角形、四角形であってもかまわない。又、突起部の先端部へタブを付着させるには、別工程で作られたリング状タブの一部を突起部の先端部に熱融着等により付着させることも可能であるが、注出口付きキャップを成型する際に、同時に一体成形するのが、工程が簡単で好ましい。
【００１６】
本発明の流出量切り替え可能な注出口付きキャップを装着した容器から少量の液体を注出する時には、図３に示す如く、突起部を注出口側と反対側に倒し、注出口の内側を塞いでいる封止部の内面を注出口より少し離し、注出口を一部開栓状態にする。そして、容器を傾けて内容物の液体を注ぎ出す。
【００１７】
又、本発明の流出量切り替え可能な注出口付きキャップを装着した容器から多量の液体を注出するには、図４に示す如く、リング状タブを引っ張り、注出口の内側を塞いでいる封止部の内面を注出口より大きく離し、注出口を完全に開栓状態にする。そして、容器を傾けて内容物の液体を注ぎ出す。
尚、注出口付きキャップの周囲縁部に引掛部が有ると、引っ張られたタブを該引掛部に引っ掛けて止めることができるので、両手で容器を傾けて内容物の液体を注出することが出来る。その結果、注出された液体を注がれる器より漏らすことがない。
【００１８】
容器内の液体を全て注出させずに残す場合は、必要量だけ注出した後、注出口の先端にキャップを取り付けておくと、注出口の中に雑菌が付着したり、或は、注出口の中に付着していた液体が雫となって落下することがない。
【００１９】
【作用及び効果】
本発明の流出量切り替え可能な注出口付きキャップを備えた容器は、突起部を傾けることにより、注出口の内側を塞いでいる封止部を注出口より少し離して一部だけ開栓状態にすることができるので、注出量を少なくすることが出来る。又、リング状タブを引っ張ることにより、注出口の内側を塞いでいる封止部を注出口より大きく離し、完全に開栓状態にすることができるので、注出量を多くすることが出来る。
そのため、本発明の流出量切り替え可能な注出口付きキャップを備えた容器は、短時間で多量の液体を注出することが出来るばかりか、少量の液体も精度よく注出することも出来るので、業務用の醤油や食料油等の容器に非常に有益である。

BACKGROUND OF THE INVENTION
The present invention relates to a cap with a spout attached to a spout of a container such as an inner bag for a bag-in-box. More specifically, the present invention relates to a cap with a spout capable of switching a spout amount when a liquid in a container is spouted.
[0002]
A cap with a spout attached to a spout of a container such as an inner bag for a bag-in-box is composed of the tip (opening) of the spout that closes the inside of the spout and the inner surface of the sealing portion of the cap that is inscribed therein The inner surface of the sealing part was separated from the inside of the spout, and the liquid in the container was poured out after the spout was opened. As a method of separating the inner surface of the sealing part that closes the inside of the spout from the spout, a method of pulling a tab attached to the upper surface of the sealing part or a tilting of the protrusion attached to the upper surface of the sealing part There are methods.
[0003]
And when pouring out the liquid of the contents from a container such as an inner bag for bag-in-box, when pouring a large amount of contents at a time, a method with a large amount of pouring from the pouring outlet is preferred, and a small amount In the case where only the contents of are poured out, a method in which the amount poured out from the outlet is small is preferable.
[0004]
However, in each of the above-described methods, it is difficult to adjust the dispensing amount when the liquid of the contents is poured out. That is, when pulling the tab attached to the upper surface of the sealing portion, the upper surface of the sealing portion is curved to form a recess, and therefore, when the tab is pulled, the ring-shaped tab extends, making it difficult to adjust the force. However, it is always in a sufficiently pulled state, the amount of dispensing cannot be adjusted, and the amount of dispensing becomes constant. Also, when the protrusion attached to the upper surface of the sealing part is tilted, the protrusion is short, and because it is attached to the substantially central part of the sealing part, the protrusion is always tilted sufficiently. It becomes a state, the amount of dispensing cannot be adjusted, and the amount of dispensing becomes constant.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a cap with a spout that can easily adjust a spout amount when a liquid in a container is spouted.
And when trying to pour out a large amount of liquid from a container such as a bag-in-box inner bag at the same time or when only a small amount of liquid is poured out, it is intended to be able to pour out easily. It is.
[0006]
In order to solve the above-mentioned problem, the present invention uses a method of pulling a tab attached to the upper surface of the sealing portion of the cap with spout and a method of tilting the protrusion attached to the upper surface of the sealing portion. I found. That is, the protrusion (4) adheres to the upper surface (31) of the sealing portion (3) that is inscribed in the tip opening of the spout or the like and closes the inner side (21) of the spout (2), and A ring-shaped tab (5) is attached to the tip (41) of the protrusion (4). Preferably, the protrusion part (4) adhering to the sealing part (3) is adhering to the spout (2) side rather than the center part of the sealing part (3). More preferably, the base part (42) of the protrusion (4) adhering to the sealing part (3) is thicker toward the spout (2) side.
[0007]
The container to which the cap with a spout capable of switching the outflow amount of the present invention is not particularly limited, but a spout having a hole formed in a bag made from a plastic film and having an opening in the hole is provided. A container attached by heat fusion or the like, for example, an inner bag for a bag-in-box or the like is suitable. Moreover, the size of a container such as an inner bag for a bag-in-box to which the cap with a spout of the present invention is attached is preferably 5 to 20 liters.
[0008]
The material constituting the cap with a spout capable of switching the outflow amount of the present invention is not particularly limited, and synthetic resins conventionally used for caps can be mentioned. In particular, since the cap with a spout according to the present invention is a mechanism for deforming and opening the sealing portion, a flexible synthetic resin such as a thermoplastic elastomer is suitable for the sealing portion. Moreover, since it is a mechanism which inclines a protrusion part and deform | transforms a sealing part, what consists of a synthetic resin whose hardness is higher than a sealing part is preferable. That is, the synthetic resin constituting the cap does not necessarily need to be the same synthetic resin, but it is preferable to use a suitable synthetic resin for each member.
[0009]
Hereinafter, the cap with a spout capable of switching the outflow amount according to the present invention will be described in detail with reference to the drawings.
Of course, the cap with a spout of the present invention is not limited to the shape shown in the drawings.
FIG. 1 is a schematic cross-sectional view showing a state in which a cap with a spout of the present invention is attached to a spout of a container.
FIG. 2 is a schematic plan view of the cap with a spout of the present invention.
FIG. 3 is a schematic cross-sectional view showing a state in which the protrusion in the cap with a spout of the present invention is tilted to pour out the liquid in the container.
FIG. 4 is a schematic cross-sectional view showing a state when the liquid in the container is poured out by pulling the ring-shaped tab of the cap with a spout of the present invention.
[0010]
First, the spout (8) which has a front-end | tip opening part is attached to the container which mounts the cap (1) with a spout which can change outflow amount of this invention. And the cap (1) with a spout of this invention is sealing the front-end | tip part (81) of a spout (8) and the cap with a spout (1) inscribed in this as shown in FIG. 1 in a normal state. The inner side (21) of the spout (2) is closed by the inner surface (32) of the part (3), so that the spout is completely sealed. That is, when the cap with spout of the present invention is attached to the spout attached to the container, the sealing portion is curved inward to form a concave shape, and has flexibility, The inner surface of the curved sealing portion is in close contact with the inside of the spout and is in a state of completely closing the inside of the spout together with the tip of the spout. The shape of the spout may be circular or rectangular.
[0011]
And the protrusion part (4) has adhered to the upper surface (31) of the sealing part (3).
As a position where the projection part (4) is attached to the upper surface (31) of the sealing part (3), it is preferable that it is located on the spout (2) side from the center part of the sealing part (3). . When the protruding portion (4) is tilted when the protruding portion (4) is inclined, the position where the protruding portion (4) is attached is on the side opposite to the spout (2) side from the central portion of the sealing portion (3). It is difficult to cause (3) to deform so as to open the spout (2). Further, when the position where the protrusion (4) is attached is close to the spout (2), the amount of pouring decreases. Therefore, the position where the protrusion is attached may be appropriately determined so as to obtain a desired amount when the protrusion is tilted.
In general, since the amount of extraction when the ring-shaped tab is pulled increases, it is preferable that the amount of extraction when the protrusion is inclined is small.
[0012]
Moreover, it is preferable that the projection part (4) attached to the sealing part (3) is such that the root part (42) becomes thicker toward the spout (2). When the base (42) of the protrusion (4) is thicker toward the spout (2), the seal that closes the inside of the spout (2) when the protrusion (4) is tilted. The stopper (3) is deformed and the spout (2) is easily opened.
That the base (42) of the protrusion (4) is thicker toward the spout (2) side is that the protrusion (4) itself is thicker toward the spout (2). Of course, the bottom of the protrusion (4) has a plate-like body attached so as to protrude toward the spout (2), or the base side surface and protrusion on the spout (2) side of the protrusion (4) Examples thereof include a rectangular bar-like body, a triangular plate-like body and the like attached so as to be joined to the upper surface (31) of the sealing portion (3) on the base side surface between the portion and the spout.
[0013]
In addition, since a projection part deform | transforms a sealing part, it is preferable to have the hardness which does not curve even if it inclines with a fingertip. Further, the height of the protrusion is not particularly limited, but it is preferable that the protrusion can be tilted with a fingertip and that the protrusion can be accommodated in the curved concave portion of the sealing portion. If the protruding portion protrudes from the curved concave portion of the sealing portion, not only the appearance deteriorates, but there is a risk that the protruding portion is inclined by touching something and the liquid in the container leaks.
[0014]
Furthermore, a ring-shaped tab (5) is attached to the tip (41) of the protrusion (4).
If the ring-shaped tab (5) is attached to the tip (41) of the protrusion (4), when the ring-shaped tab (5) is pulled, the spout ( The sealing part (3) closing the inside of 2) can be largely deformed to make it completely open, and a large amount of liquid can be poured out.
[0015]
Further, when the tab has a ring shape, the fingertip can be inserted into the ring and pulled easily. In addition, when the tab is in a ring shape, the pulled tab can be hooked on the hook portion (71) of the peripheral edge portion (7) of the cap and stopped.
Note that the ring shape does not necessarily need to be a circle, and may be a triangle or a rectangle. Also, in order to attach the tab to the tip of the projection, it is possible to attach a part of the ring-shaped tab made in a separate process to the tip of the projection by heat fusion or the like. When molding the cap with cap, it is preferable to perform integral molding at the same time because the process is simple.
[0016]
When a small amount of liquid is poured out from a container equipped with a cap with a spout according to the present invention capable of switching the outflow amount, as shown in FIG. 3, the protrusion is tilted to the side opposite to the spout to close the inside of the spout. The inner surface of the protruding sealing part is slightly separated from the spout and the spout is partially opened. Then, the container is tilted and the liquid of the contents is poured out.
[0017]
Also, in order to pour a large amount of liquid from a container equipped with a cap with a spout capable of changing the outflow amount of the present invention, as shown in FIG. 4, a ring-shaped tab is pulled to seal the inside of the spout. Keep the inner surface of the stop part far away from the spout and completely open the spout. Then, the container is tilted and the liquid of the contents is poured out.
If there is a hook on the peripheral edge of the cap with a spout, the pulled tab can be hooked and stopped on the hook, so that the container can be tilted with both hands and the liquid of the contents can be poured out. I can do it. As a result, the dispensed liquid is not leaked from the poured device.
[0018]
When leaving all the liquid in the container without pouring out, if a cap is attached to the tip of the spout after pouring out the required amount, various bacteria may adhere to the spout, or The liquid adhering to the outlet does not fall as a trap.
[0019]
[Action and effect]
The container having a cap with a spout capable of switching the outflow amount according to the present invention is in a partially opened state by slightly tilting the protruding portion so that the sealing portion blocking the inside of the spout is slightly separated from the spout. Therefore, it is possible to reduce the amount dispensed. In addition, by pulling the ring-shaped tab, the sealing portion blocking the inside of the spout can be greatly separated from the spout and can be completely opened, so that the amount of pouring can be increased.
Therefore, the container equipped with a cap with a spout capable of switching the outflow amount of the present invention can not only dispense a large amount of liquid in a short time, but also can dispense a small amount of liquid accurately. It is very useful for containers such as commercial soy sauce and food oil.
