Description

本発明は、抜栓式キャップのプルリング、特に、指掛かりをよくしたプルリングに関するものである。   TECHNICAL FIELD The present invention relates to a pull ring for a stopper cap, and more particularly to a pull ring with improved finger grip.

内容液を収納する容器の口筒部に装着するキャップにおいて、キャップの除去部に設けた支柱部とリング部とからなるプルリングを引き上げ、開口を開設するようにした抜栓式キャップは従来より周知である（例えば、特許文献１、２参照）。
特開平８−１０４３５０号公報 特開２０００−２７２６４８号公報 A cap that is attached to the mouth tube portion of a container for storing content liquid, and has been well known in the art as a plug-type cap that has been opened by opening a pull ring consisting of a column portion and a ring portion provided in the removal portion of the cap. (For example, refer to Patent Documents 1 and 2).
JP-A-8-104350 JP 2000-272648 A

しかしながら、従来周知の抜栓式キャップでは、抜栓の際に、リング部が切れてしまうことを防止するために、一定の断面積を確保するとともに、成形時にプルリングの金型からの離型性をよくするため、リング部の厚みを薄くしていた。
そのため、リング部の上下方向の長さが長くなり、リング部の内周に指を掛ける際に、指の掛かりが悪いという問題があった。 However, in the known cap-type cap, in order to prevent the ring part from being cut during the plug-out, a certain cross-sectional area is ensured and the mold release property of the pull ring is improved during molding. Therefore, the thickness of the ring part was made thin.
For this reason, the length of the ring portion in the vertical direction becomes long, and there is a problem that the finger is badly hooked when the finger is placed on the inner periphery of the ring portion.

本発明は、上記の問題を解決することを課題とし、リング部が長さ方向で一定の応力を維持し、抜栓の際に、指の掛かりがよいプルリングを提供することを目的とする。   An object of the present invention is to provide a pull ring in which the ring portion maintains a constant stress in the length direction and has a good finger engagement when unplugged.

本発明は、上記の課題を解決するため、プルリングとして、抜栓式キャップの注出口を開口する隔壁の除去部上面に配設されたプルリングにおいて、プルリングは、除去部に連設される支柱部と、支柱部に連設される円環状のリング部とを具え、リング部の支柱部の反対側は、リング部の他の部分の上下方向の長さより短く形成された指掛け部となっていることを特徴とする構成を採用する。   In order to solve the above-described problems, the present invention provides a pull ring as a pull ring disposed on an upper surface of a removal portion of a partition wall that opens a spout of a stopper cap. And an annular ring portion connected to the column portion, and the opposite side of the ring column column portion is a finger hook portion formed shorter than the vertical length of the other portion of the ring portion. A configuration characterized by the above is adopted.

リング部の実施例として、リング部の指掛け部の肉厚が、リング部の他の部分の肉厚に比べ、厚く形成されていることを特徴とする構成を採用する。   As an embodiment of the ring portion, a configuration is adopted in which the thickness of the finger hook portion of the ring portion is formed thicker than the thickness of the other portions of the ring portion.

抜栓式キャップの注出口を開口する隔壁の除去部上面に配設されたプルリングにおいて、リング部の支柱部の反対側が、リング部の他の部分の上下方向の長さより短く形成された指掛け部となっていることによって、リング部に指を掛ける際に、指掛け部に指を掛けることで、指の掛かりをよくすることができるようになった。
また、指掛け部の肉厚を厚くすることによって、リング部の切断を防ぐことができるようになった。 In the pull ring disposed on the upper surface of the removal portion of the partition wall that opens the spout of the unplugged cap, a finger hook portion formed on the opposite side of the support portion of the ring portion shorter than the vertical length of the other portion of the ring portion; As a result, when a finger is placed on the ring part, it is possible to improve the hooking of the finger by placing the finger on the finger rest part.
Further, the ring portion can be prevented from being cut by increasing the thickness of the finger-hanging portion.

次に、本発明のプルリングの実施形態について、図面を参照して説明する。
図１において、Ａは容器の口筒部に嵌着されるとともに、上部に蓋体を装着して閉蓋されるキャップ本体である。 Next, an embodiment of the pull ring of the present invention will be described with reference to the drawings.
In FIG. 1, A is a cap main body that is fitted to the mouth tube portion of the container and is closed by attaching a lid to the top.

キャップ本体Ａは、注出筒１と、注出筒１内周に配設される隔壁２とを具えている。   The cap main body A includes a dispensing cylinder 1 and a partition wall 2 disposed on the inner periphery of the dispensing cylinder 1.

隔壁２には、注出口を開口する薄肉の弱化部３により除去部４が設けられており、除去部４の上面の所定の位置には、開口時に除去部４を引上げるプルリング５が設けられている。   The partition wall 2 is provided with a removal portion 4 by a thin weakened portion 3 that opens the spout, and a pull ring 5 that pulls up the removal portion 4 at the time of opening is provided at a predetermined position on the upper surface of the removal portion 4. ing.

プルリング５は、図１、２に示すように、隔壁２の除去部に連設される支柱部６と、支柱部６の上部に連設される円環状のリング部７とからなっている。   As shown in FIGS. 1 and 2, the pull ring 5 includes a support column 6 that is connected to the removal portion of the partition wall 2 and an annular ring unit 7 that is connected to the top of the support column 6.

リング部７の支柱部６の反対側は、指掛け凹部８が下部に凹設され、リング部７の他の部分の上下方向の長さより短く形成された指掛け部７ａとなっている。   On the opposite side of the column portion 6 of the ring portion 7, a finger hanging concave portion 8 is formed in the lower portion, and a finger hanging portion 7 a formed shorter than the vertical length of the other portion of the ring portion 7 is formed.

次に、本発明のプルリングの作用効果について説明する。
本発明のプルリング５は、キャップ本体Ａの隔壁２から除去部４を抜栓して開口するため、リング部７の内周に指を掛ける際に、図２に示すように、リング部７の指掛け部７ａが他のリング部７の上下方向の長さより短く形成されているとともに、リング部７に指掛け凹部８が形成されているので、リング部７の内周および下部に指が掛かり易い。 Next, the effect of the pull ring of this invention is demonstrated.
Since the pull ring 5 of the present invention is opened by removing the removal portion 4 from the partition wall 2 of the cap body A, when the finger is hung on the inner periphery of the ring portion 7, as shown in FIG. The portion 7a is formed shorter than the length of the other ring portion 7 in the vertical direction, and the finger-hanging recess 8 is formed in the ring portion 7. Therefore, it is easy to put a finger on the inner periphery and the lower portion of the ring portion 7.

リング部７の指掛け部７ａが、他のリング部７の上下方向の長さより短く形成されているので、指掛け部７ａの強度が弱くなり、指掛け部７ａを引張った際に切断してしまうことも考えられるが、リング部７の指掛け部７ａの肉厚を、他のリング部７の肉厚に比べ、若干厚くして形成することで充分な強度を設定することができ、指掛け部７ａを引張った際に、指掛け部７ａが切断することを防止することができる。   Since the finger-hanging portion 7a of the ring portion 7 is formed to be shorter than the length of the other ring portion 7 in the vertical direction, the strength of the finger-hanging portion 7a becomes weak and may be cut when the finger-hanging portion 7a is pulled. Although it is conceivable, a sufficient strength can be set by forming the finger-hanging portion 7a of the ring portion 7 slightly thicker than the thickness of the other ring portions 7, and the finger-holding portion 7a can be pulled. In this case, it is possible to prevent the finger-hanging portion 7a from being cut.

また、リング部７の指掛け部７ａが他に比べ肉厚が厚くても、キャップ本体Ａの成形時の型抜きにあたって、リング部７の支柱部６側を支点に他のリング部７が変形するので、型抜きには、ほとんど影響がない。   Even when the finger-hanging portion 7a of the ring portion 7 is thicker than the other, when the cap body A is molded, the other ring portion 7 is deformed with the support portion 6 side of the ring portion 7 as a fulcrum. Therefore, there is almost no influence on die cutting.

上記実施形態では、プルリング５の円環状のリング部７は、支柱部６の上部に連設されているが、リング部の支柱部の反対側に指掛け部を形成することができればよいので、リング部の形状を、図３に示すように、隔壁２から延びる支柱部１０と、支柱部１０の上部両側から前方外側および上方に向かってＶ字状に延び、かつ円環状に形成されるリング部１１とし、リング部１１の支柱部１０の反対側に凹設した指掛け凹部１２により、他のリング部１１の上下方向の長さより短く形成された指掛け部１１ａが形成されるようにしても、上記実施形態と同様の効果が得られる。   In the above embodiment, the annular ring portion 7 of the pull ring 5 is connected to the upper portion of the column portion 6, but it is sufficient that a finger hook portion can be formed on the opposite side of the column portion of the ring portion. As shown in FIG. 3, the shape of the part is a column part 10 extending from the partition wall 2, and a ring part formed in an annular shape extending in a V shape from both sides of the upper part of the column part 10 toward the front outer side and upward. 11 and the finger-hanging recess 12 that is recessed on the opposite side of the column portion 10 of the ring portion 11 forms a finger-hanging portion 11a that is shorter than the length of the other ring portion 11 in the vertical direction. The same effect as the embodiment can be obtained.

上記実施形態では、キャップ本体Ａとしたが、本発明は、除去部を除去して開口する隔壁の除去部に連設するプルリングに関しての発明であり、キャップ本体および上蓋の他の構成はどのようなものでもよく、また、キャップ本体ではなく、キャップ内に装着される中栓の隔壁のプルリングの構成としてもよい。
つまり、除去部を除去して開口する隔壁であれば、本願のプルリングの構成を採用することができ、他の構成は上記実施形態の構成に限定されない。 In the above embodiment, the cap main body A is used. However, the present invention relates to a pull ring that is connected to the removal portion of the partition wall that is opened by removing the removal portion, and how are other configurations of the cap main body and the upper lid. It is also possible to use a pull ring structure for the partition wall of the inner plug mounted in the cap instead of the cap body.
That is, the structure of the pull ring of the present application can be adopted as long as the partition wall is opened by removing the removal portion, and the other structure is not limited to the structure of the above embodiment.

本発明は、除去部を除去して開口する隔壁の除去部に連設するプルリングにおいて、リング部の指掛け部が、他の部分の上下方向の長さより短く形成させることによって、リング部に指が掛かり易くすることができるので、各種容器のプルリングとして、広く利用することができる。   According to the present invention, in the pull ring connected to the removal portion of the partition wall that is opened by removing the removal portion, the finger hooking portion of the ring portion is formed to be shorter than the vertical length of the other portion, so that the finger is placed on the ring portion. Since it can be easily hooked, it can be widely used as a pull ring for various containers.
