Abstract

<P>PROBLEM TO BE SOLVED: To provide a highly sealable hinged cap. <P>SOLUTION: The hinged cap is equipped with a cap body (1) having an opening to permit a content in a container to pass through and fixedly held on a mouth of the container, and a lid (2) swingably supported on the cap body (1) via a hinge and combined with the cap body (1) for sealing the mouth of the container. The cap body (1) is equipped with an inner ring (3) surrounding the opening. The lid (2) is equipped with a seal ring (4) elastically supported via a thin part (2a) and in contact with the tip of the inner ring (3) for keeping the container liquid-tightly. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、ワンタッチでの開閉を可能とするヒンジキャップに関し、該キャップのシール性をより一層高めて液漏れを確実に防止しようとするものである。   The present invention relates to a hinge cap that can be opened and closed with a single touch, and further enhances the sealing performance of the cap to reliably prevent liquid leakage.

食用油や醤油等を入れるボトル型の容器には、一般に片手操作でもって簡単に容器の開閉ができるようにヒンジキャップが装着されているのが普通である。   In general, a bottle-type container containing edible oil or soy sauce is generally provided with a hinge cap so that the container can be easily opened and closed by one-handed operation.

この種のキャップは液垂れを防止する観点からキャップ本体にはインナーリング（注出筒）が、また、蓋体には該インナーリングと当接して液漏れを回避するシールリングが設けられている（例えば特許文献１参照）が、該インナーリングとシールリングとの当接度合いは同じラインで製造されている場合であっても寸法にばらつきが生じることがあり、シール性が安定せず成形の際の品質管理が難しいのが現状であった。   This type of cap is provided with an inner ring (pouring cylinder) on the cap body from the viewpoint of preventing liquid dripping, and a seal ring is provided on the lid to avoid liquid leakage by contacting the inner ring. (For example, see Patent Document 1) However, even if the contact degree between the inner ring and the seal ring is manufactured in the same line, the dimensions may vary, and the sealing performance is not stable and the molding is not stable. At present, quality control is difficult.

本発明の課題は、上述のような従来の問題を解消できる新規なヒンジキャップを提案するところにある。   The subject of this invention exists in the place which proposes the novel hinge cap which can eliminate the above conventional problems.

本発明は、容器内の内容物を通過させる開口を有し該容器の口部に固定保持されるキャップ本体と、このキャップ本体にヒンジを介して揺動可能に支持されキャップ本体と合わさって容器の口部を密閉する蓋体とを備え、
前記キャップ本体に、開口を取り囲むインナーリングを設け、
前記蓋体に、薄肉部を介して弾性支持され該インナーリングの先端に当接して容器を液密状態に維持するシールリングを設けたことを特徴とするヒンジキャップである。 The present invention has a cap body having an opening for allowing the contents in the container to pass therethrough and fixedly held at the mouth of the container, and is supported by the cap body through a hinge so as to be swingable. And a lid for sealing the mouth of the
An inner ring surrounding the opening is provided in the cap body,
The hinge cap is characterized in that the lid is provided with a seal ring that is elastically supported through a thin wall portion and abuts against the tip of the inner ring to maintain the container in a liquid-tight state.

上記の構成になるヒンジキャップの前記薄肉部は、シールリングの周りの少なくとも一部分を取り囲むように蓋体に設けられたものが望ましい。   The thin portion of the hinge cap configured as described above is preferably provided on the lid so as to surround at least a portion around the seal ring.

蓋体に薄肉部を設けてこの薄肉部の変位によってシールリングを弾性支持することで、シールリングとインナーリングの接触圧力が安定化され高いシールが可能となる。   By providing a thin portion on the lid and elastically supporting the seal ring by the displacement of the thin portion, the contact pressure between the seal ring and the inner ring is stabilized and high sealing is possible.

以下、図面を用いて本発明をより具体的に説明する。
図１は合成樹脂からなる本発明にしたがうヒンジキャップの実施の形態を示したものである。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows an embodiment of a hinge cap made of a synthetic resin according to the present invention.

図において１は容器内の内容物を通過させる注出口を有し容器の口部に固定保持されるキャップ本体、２はキャップ本体１にヒンジｈを介して揺動可能に支持されキャップ本体１と合わさって容器の口部を密閉する蓋体、３はキャップ本体１の開口を取り囲むインナーリングである。このインナーリング３は内容物を注出する際に液垂れを防止するためその先端にリップ３ａを有する。   In the figure, reference numeral 1 denotes a cap main body having a spout for allowing the contents in the container to pass through, and fixedly held at the mouth of the container. A lid 3 that seals the mouth of the container together is an inner ring that surrounds the opening of the cap body 1. The inner ring 3 has a lip 3a at the tip thereof to prevent dripping when the contents are poured out.

また、４は蓋体２の裏面に一体的に設けられたシールリングである。このシールリング４は蓋体２を薄肉化した薄肉部２ａを介して弾性支持されており、蓋体２を閉じたとき、その先端がインナーリング３の先端に当接して容器を液密状態に維持する。   Reference numeral 4 denotes a seal ring provided integrally on the back surface of the lid 2. The seal ring 4 is elastically supported through a thinned portion 2a obtained by thinning the lid 2. When the lid 2 is closed, the tip of the seal ring 4 comes into contact with the tip of the inner ring 3 to bring the container into a liquid-tight state. maintain.

シールリング４は、蓋体２の薄肉部２ａにより弾性支持された状態にあり、該シールリング４あるいはインナーリング３の寸法に多少のばらつきがあっても蓋体２を閉じたとき両者は安定した圧力でもって当接する（とくにシールリング４がインナーリング３に強く突き当たっても薄肉部２ａの弾性変形により圧力が軽減される）ことから確実なシールが可能となり、開栓状態（プルリングを介して障壁を引きちぎって注出開口を形成した状態）にある容器が転倒しても液漏れが起きることはない。また、このような安定した圧力による当接は、蓋体２をキャップ本体１に係止するアンダーカットのような係止部５に対して変形を伴うような余計な力を及ぼすことがないので蓋体２がキャップ本体１から簡単に外れることもない。   The seal ring 4 is elastically supported by the thin portion 2a of the lid 2, and both of them are stable when the lid 2 is closed even if there is some variation in the dimensions of the seal ring 4 or the inner ring 3. Abuts with pressure (especially, even if the seal ring 4 strongly hits the inner ring 3, the pressure is reduced by the elastic deformation of the thin portion 2 a), so that a reliable seal is possible, and the plug is opened (barrier via the pull ring). Even if the container in a state where the dispensing opening is formed by tearing off the liquid, the liquid does not leak. Further, the contact by such a stable pressure does not exert an extra force that causes deformation on the locking portion 5 such as an undercut for locking the lid 2 to the cap body 1. The lid 2 is not easily detached from the cap body 1.

薄肉部２ａはシールリング４の全周でもよいし図２に示すように一部分に設けてもよく薄肉部２ａの形成領域についてはとくに限定されない。   The thin portion 2a may be the entire circumference of the seal ring 4 or may be provided in a part as shown in FIG.

また、該薄肉部２ａは蓋体２の裏面に設ける場合について示したが表面に設けてもよい。   Moreover, although the thin part 2a was shown about the case where it provides in the back surface of the cover body 2, you may provide in the surface.

インナーリングとシールリングが安定した圧力でもって当接しその相互間で確実にシールできるヒンジキャップが提供できる。   It is possible to provide a hinge cap in which the inner ring and the seal ring are brought into contact with each other with a stable pressure and can be reliably sealed with each other.

本発明にしたがうヒンジキャップの実施の形態を示した図である。It is the figure which showed embodiment of the hinge cap according to this invention. 本発明にしたがうヒンジキャップの他の例を示した図である。It is the figure which showed the other example of the hinge cap according to this invention.
