Description

本発明は、プルリングにて密閉障壁を引きちぎることで開栓する合成樹脂製の注出キャップに関するものであり、開栓時に形成されるのが避けられなかった注出開口におけるバリ状の破断片を皆無にしようとするものである。   The present invention relates to a synthetic resin pouring cap that is opened by tearing off a hermetic barrier with a pull ring. It is something that is going to be completely absent.

プルリングを介して密閉障壁を引きちぎって注出開口を形成する注出キャップは、不正な開封を確実に防止することが可能であること、また、容器を高い密封状態に維持して品質を長期にわたって保持できることから、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）。   A pour cap that tears the sealing barrier through the pull ring to form a pour opening can reliably prevent unauthorized opening, and maintain the container in a highly sealed condition for long-term quality. Since it can hold | maintain, it is frequently used for the container etc. which put edible oil, soy sauce, a drink, etc. (for example, refer patent document 1).

特開平１０−１６７３０８号公報JP 10-167308 A

ところで、この種の注出キャップは、密閉障壁を引きちぎる際に注出開口の縁にバリ状の破断片が形成されやすいため、見た目が悪いばかりか、内容物を注出する際に該破断片に内容物が衝突して飛び散ることがありその改善が求められていた。   By the way, this kind of pouring cap is not only bad in appearance because it tends to form a burr-like broken piece at the edge of the pouring opening when the sealing barrier is torn off. The contents collided with each other and scattered.

本発明の課題は、密閉障壁を引きちぎる際に形成されるのが避けられなかったバリ状の破断片を皆無にできる新規な注出キャップを提案するところにある。   An object of the present invention is to propose a novel dispensing cap that can eliminate any burr-like fracture pieces that are unavoidably formed when the sealing barrier is torn.

本発明は、容器の口部に固定保持されるベースと、このベースに一体成形され破断予定線に沿う引きちぎりによって注出開口を形成する密閉障壁と、ベースに合わさり該注出開口を液密状態に保持する蓋体とからなる注出キャップであって、
前記破断予定線は、前記密閉障壁を該密閉障壁の厚さ方向下側に向けて開口させた凹状の切欠き溝からなり、
前記切欠き溝は、相互に近接する向きに傾斜させた対向配置になる側壁と、各側壁が最も近接した一番深い部位をつなぐ連結片とを備え、
前記連結片は、前記各側壁とつながる部位に密閉障壁の最薄肉部を形成する２つのノッチを有することを特徴とする注出キャップである。 The present invention includes a base fixedly held at the mouth of a container, a sealing barrier that is integrally formed with the base and that forms a pour opening by tearing along a planned fracture line, and a base that is liquid-tight. A pouring cap consisting of a lid that holds in a state;
The planned fracture line consists of a concave notch groove in which the hermetic barrier is opened downward in the thickness direction of the hermetic barrier,
The notch groove includes a side wall that is opposed to each other and inclined in a direction close to each other, and a connecting piece that connects the deepest part where each side wall is closest,
The connecting piece is a pouring cap characterized in that it has two notches forming the thinnest wall portion of the hermetic barrier at a portion connected to each side wall .

プルリングを引っ張って該密閉障壁を引きちぎると、最薄肉部のうちの１つから分断されるためバリ状の破断片は形成されず、この時、他の最薄肉部は密閉障壁を弾性変位させる基点として作用して引きちぎりに要する力を緩和して開け易い感触が与えられる。   When pulling the pull ring and tearing off the sealing barrier, it breaks from one of the thinnest parts, so no burr-like fracture fragments are formed. At this time, the other thinnest part is a base point that elastically displaces the sealing barrier Acting to reduce the force required for tearing, giving a feel that is easy to open.

以下、図面を用いて本発明をより具体的に説明する。
図１（ａ）（ｂ）は本発明にしたがう注出キャップ（合成樹脂製）の実施の形態を示したものであり、図２は図１の要部断面の拡大図、そして図３は密閉障壁を引きちぎって開栓した状態を示した底面図である。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 (a) and 1 (b) show an embodiment of a pouring cap (made of synthetic resin) according to the present invention, FIG. 2 is an enlarged view of the cross section of the main part of FIG. 1, and FIG. It is the bottom view which showed the state opened by tearing off the barrier.

図における１は容器の口部にねじあるいはアンダーカット嵌合にて固定保持されるベース、２はこのベース１に一体成形され破断予定線Ｓに沿う引きちぎりによって注出開口ｈ（図３参照）を形成する密閉障壁、３はベース１にヒンジ４を介して揺動可能に保持される蓋体であって、この蓋体３はベース１に合わさり注出開口ｈを液密状態に保持することができるようになっている。   In the figure, reference numeral 1 denotes a base fixed to the mouth of the container by screwing or undercut fitting. 3 is a lid body that is swingably held on the base 1 via a hinge 4. The lid body 3 is fitted to the base 1 and holds the dispensing opening h in a liquid-tight state. Can be done.

また、５はベース１に注出開口ｈを取り囲むように一体的に配置されたインナーリング、６は蓋体３に設けられインナーリング５に当接してその相互間でシールするシールリング、７は密閉障壁２につながり該障壁２の引きちぎりを誘導するプルリングである。   Further, 5 is an inner ring that is integrally disposed in the base 1 so as to surround the pouring opening h, 6 is a seal ring that is provided on the lid 3 and abuts against the inner ring 5 and seals between them, 7 The pull ring is connected to the hermetic barrier 2 to induce tearing of the barrier 2.

注出キャップの破断予定線Ｓは、その要部を拡大して図２に示す如く、相互に近接する向きに傾斜させた対向配置になる側壁Ｓ１、Ｓ２と、各側壁Ｓ１、Ｓ２が最も近接した部位で２つのノッチｎ１、ｎ２を形成しそのノッチｎ１、ｎ２を密閉障壁２の最薄肉部とする連結片８とを有し、密閉障壁２の厚さ方向に向けて凹とした切り欠溝からなっている。 Breakable line S of dispensing cap, as shown in FIG. 2 an enlarged main portion thereof, and the side wall S 1, S 2 to be opposite a tilted arrangement in a direction close to each other, each side wall S 1, S 2 has a notch n 1 , n 2 in the closest part, and a connecting piece 8 having the notches n 1 , n 2 as the thinnest wall portion of the hermetic barrier 2, and the thickness direction of the hermetic barrier 2 It consists of a notch groove that is concave toward the top.

従来の注出キャップの破断予定線Ｓ´はその断面形状を図４に示すように対向する側壁の接点に平坦面ｔを有しており、密閉障壁２の引きちぎりに際してはその平坦面ｔの何れかにおいて分断されることになるため図５に示すようなバリ状の破断片ｔ´が形成されるのは避けられなかったが、本発明にしたがう注出キャップにおいては、プルリング７を引っ張って密閉障壁２を引きちぎるとき、ノッチｎ１、ｎ２の何れか一方の最薄肉部から分断されるためバリ状の破断片が形成されることはなく、しかも、残りのもう一方の最薄肉部ではそこを基点にして密閉障壁２を弾性変形させることになり比較的小さな力で開栓できる感触が付与され開け易い。 As shown in FIG. 4, the conventional breaking cap fracture line S ′ has a flat surface t at the contact of the opposite side wall as shown in FIG. 4, and when the sealing barrier 2 is torn off, It is inevitable that a burr-shaped fracture piece t ′ as shown in FIG. 5 is formed because it is divided at any point. However, in the pouring cap according to the present invention, the pull ring 7 is pulled. When the sealing barrier 2 is torn off, it is divided from one of the thinnest portions of the notches n 1 and n 2 , so that no burr-like fracture fragments are formed, and in the other thinnest portion, The sealing barrier 2 is elastically deformed from that point as a starting point, and a touch that can be opened with a relatively small force is imparted and is easy to open.

上掲図１に示した例では連結片８を逆台形状として示したが、該連結片８は図６に示すような円弧状あるいは図７に示すような逆三角形状でもよく、その形状についてはとくに限定されない。   In the example shown in FIG. 1, the connecting piece 8 is shown as an inverted trapezoidal shape. However, the connecting piece 8 may have an arc shape as shown in FIG. 6 or an inverted triangular shape as shown in FIG. Is not particularly limited.

ノッチは２つ設けた場合について示したが、３つ以上設けてもよく、注出キャップのサイズや内容物の種類に応じて任意に選択できる。   Although the case where two notches are provided is shown, three or more notches may be provided and can be arbitrarily selected according to the size of the extraction cap and the type of contents.

側壁Ｓ１、Ｓ２については図示のようなフラットな壁面を有するものが適用できるが、図８（ａ）（ｂ）に示すように内向き（凹状）あるいは外向き（凸状）に湾曲させた壁面を適用してもよい。 As the sidewalls S 1 and S 2 , those having flat walls as shown in the figure can be applied, but as shown in FIGS. 8A and 8B, they are curved inward (concave) or outward (convex). Wall surfaces may be applied.

注出開口の周りにバリ状の破断片が形成されることのない注出キャップが提供できる。   It is possible to provide a pouring cap in which no burr-like broken pieces are formed around the pouring opening.
