Description
本発明は、プルリングを介して密閉栓を引きちぎって開栓するタイプの合成樹脂製の注出キャップに関するものであり、該密閉栓の引きちぎり初期（抜栓時）に起こりがちな内容物の飛びはねを回避しようとするものである。 The present invention relates to a synthetic resin pouring cap of a type that tears and opens a sealing plug via a pull ring, and the jumping of contents that tend to occur at the initial stage of tearing of the sealing plug (when unplugging) I try to avoid it.
破断予定溝に沿って密閉壁を引きちぎり注出開口を形成する注出キャップは、容器の不正な開封を防止することが可能であり、容器を高い密封状態に維持できることから、近年、食用油や醤油、飲料等を入れる容器等に多用されている（例えば特許文献１参照）。 In recent years, an edible cap that tears the sealing wall along the planned rupture groove to form a bleed opening can prevent unauthorized opening of the container and can maintain the container in a highly sealed state. And soy sauce, beverages, and other containers (see, for example, Patent Document 1).
ところで、この種の注出キャップは、内容物が高温充填され容器内が減圧されているような状態で一気に抜栓された場合に、容器が復元する反動でもって内容物が飛散することがしばしば見受けられた。 By the way, this type of pouring cap often finds that when the contents are filled at a high temperature and the inside of the container is decompressed at once, the contents scatter due to the recoil that the container restores. It was.
本発明の課題は、上記のような抜栓時の内容物の飛びはねを回避できる新規な注出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 extraction | pouring cap which can avoid the jump of the contents at the time of the above-mentioned plug opening.
本発明は、注出筒部を有し容器の口部に固定保持されるキャップ本体と、このキャップ本体の注出筒部の内側に一体成形され環状の破断予定溝を有する密閉栓と、該破断予定溝の内側直近に位置した支柱を介して該密閉栓を引き上げ破断予定溝に沿う引きちぎりにて注出開口を形成するプルリングとを備えた注出キャップであって、
前記支柱の外表面に、隣接相互間にて凹部を形成し注出筒部に向けて膨出させた横並び配列になる少なくとも２つの凸部を設け、この支柱の直近を通る破断予定溝を該支柱の外表面に沿わせて延伸させてなり、前記注出筒部と前記凹部の直近を通る破断予定溝との相互間に補強リブを設置したことを特徴とする注出キャップである。
The present invention includes a cap main body having a pouring tube portion fixedly held in the mouth portion of the container, a sealing plug integrally formed inside the pouring tube portion of the cap main body and having a ring-shaped groove to be broken, A pouring cap provided with a pull ring that pulls up the sealing plug through a support column positioned in the immediate vicinity of the planned breaking fracture and forms a dispensing opening by tearing along the breaking planned groove,
The outer surface of the support column is provided with at least two protrusions in a side-by-side arrangement in which recesses are formed between adjacent ones and are bulged toward the extraction tube, and a planned fracture groove passing through the immediate vicinity of the support column is provided. It is a pouring cap characterized in that a reinforcing rib is installed between the pouring cylinder portion and a planned fracture groove passing in the immediate vicinity of the concave portion, which is extended along the outer surface of the column.
前記凸部及び凹部はそれぞれＲ形状になるものがとくに好ましい。 It is particularly preferable that each of the convex portion and the concave portion has an R shape.
密閉栓を引き上げる支柱には隣接相互間に凹部を有する少なくとも２つの凸部が設けられており、この支柱の直近を通る破断予定溝は、その形状に沿うように伸延していることから、プルリングによって支柱を一定の力でもって引き上げたとき、凹部から凸部の頂点に至るまでの間で破断予定溝による密閉栓の引きちぎりが一旦停止され、この時形成される微小隙間から容器内へと空気が流入して容器がもとの形状に復元することとなる。 The column for pulling up the sealing plug is provided with at least two projections having a recess between adjacent ones, and the groove to be broken that passes through the column is extended so as to follow its shape. When the column is pulled up with a certain force, the tearing of the sealing plug by the groove to be broken is temporarily stopped from the concave portion to the top of the convex portion, and then the minute gap formed at this time enters the container. Air flows in and the container is restored to its original shape.
以下、図面を用いて本発明をより具体的に説明する。
図１は本発明にしたがう注出キャップの側面を断面で示した図であり、図２は図１のＡ視図（底面図）である。
Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a cross-sectional view of a side surface of a pouring cap according to the present invention, and FIG. 2 is a view (bottom view) of FIG.
図において１は容器の口部にねじあるいはアンダーカット係合によって固定保持することができるキャップ本体である。このキャップ本体１は注出筒部１ａを有する。 In the figure, reference numeral 1 denotes a cap body which can be fixedly held by a screw or undercut engagement at the mouth of the container. The cap body 1 has a dispensing cylinder portion 1a.
また、２はキャップ本体１の注出筒部１ａの内側に一体成形される密閉栓、３は密閉栓２に設けられた環状の破断予定溝、４は破断予定溝３の内側直近の密閉栓２において一体的に設けられた支柱、５は支柱４につながるプルリングである。
Further, 2 is a sealing plug integrally formed inside the dispensing cylinder portion 1 a of the
プルリング５、支柱４によって密閉栓２を引き上げると、該密閉栓２は破断予定溝３に沿って引きぎりられ注出開口を形成することになるが、支柱４とこの支柱４の外表面には、隣接相互間にて凹部４ａを形成し注出筒部１ａに向けて膨出させた横並び配列になる２つの凸部４ｂが設けられており、その直近を通る破断予定溝３はそれに沿って伸延しているため、抜栓に際して密閉栓２の引きちぎりが凹部４ａから凸部４ｂの頂点に至るまでの間で一旦停止され、この時形成される微小隙間から容器内へと空気が流入して容器が元の形状に復元することとなり、それ以降、密閉栓２が引きちぎられても内容物が飛散することはない。
When the sealing plug 2 is pulled up by the
注出筒部１ａと凹部４ａの相互間には補強リブ６が設けられていて、この補強リブ６によってその部位の強度が高められ、抜栓に際しての引きちぎり開始点は凹部４ａとなる。

密閉栓２のスムーズな引きちぎりを導くため、凹部４ａ、凸部４ｂはＲ形状（湾曲させる）とするのがよいが、本発明ではこの形状にのみ限定されるものではなく種々の形状の適用が可能である。
In order to guide the smooth tearing of the sealing plug 2, the
また、破断予定溝３は密閉栓２の裏面に設けた場合について例示したが、閉栓２の表面に設けてもよく、この点についても限定はされない。
Moreover, although the fracture | rupture planned groove |
容器内が減圧された状態にあっても抜栓時に内容物が飛散することのない注出キャップが提供できる。 Even when the inside of the container is decompressed, it is possible to provide a pouring cap that does not scatter the contents when the container is unplugged.
