本考案は、瓶成形用の予備成形品とキヤツプの
組合せからなる瓶の封緘装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bottle sealing device comprising a combination of a preform for bottle molding and a cap.
従来、瓶の封緘装置としては実開昭60−193858
号公報がある。
Conventionally, the bottle sealing device was developed in 1938.
There is a publication.
前記公報に記載された瓶の封緘装置は、短かい
円筒状に形成された密封リングの上部内側に、下
方に撓み易く形成された係留架橋部を設け、密封

して、密封つめを設け、この密封つめは、下方に
折り曲げ回動させようとしても、密封つめの背部
が、前記密封リングの下部内側のストツパーに当
接して回動できないように形成されている。 The bottle sealing device described in the above-mentioned publication has a mooring bridge section formed to be easily bent downward on the inside of the upper part of the sealing ring formed in a short cylindrical shape, and a mooring bridge part formed on the inside of the lower part of the sealing ring that can be bent. A sealing pawl is provided through a retaining bridge portion, and even if the sealing pawl is bent downward and attempted to be rotated, the back of the sealing pawl will come into contact with a stopper inside the lower part of the sealing ring so that the sealing pawl cannot be rotated. is formed.
前記密封リングは、瓶の口頚部に外嵌して押圧
すると、前記密封つめが、上方に折れ曲がり、密
封リングは下降して、口頚部に嵌着される。 When the sealing ring is fitted over the neck of the bottle and pressed, the sealing pawl is bent upward and the sealing ring is lowered and fitted onto the neck of the bottle.
そして、前記嵌着された密封リングは、上方に
引つ張られても、密封つめが、瓶の口頚部の下部
に設けられた下方溝に係合して上昇は阻止される
ものである。 Even if the fitted sealing ring is pulled upward, the sealing pawl engages with a downward groove provided at the lower part of the mouth and neck of the bottle, preventing it from rising.
そして、前記口頚部に閉塞体を螺合すると、閉
塞体のリムは、前記係留架橋部を下方に撓めて、
係留架橋部を通過し、リムが係留架橋部に脱出不
能に係止されるものである。 Then, when the closure body is screwed into the mouth and neck, the rim of the closure body bends the mooring bridge part downward,
The rim passes through the mooring bridge and is irremovably locked to the mooring bridge.
前記の如くして閉塞体を口頚部に嵌着した後
は、保持架橋部が破壊されないと閉塞体を口頚部
から開放できないものである。 After the closure is fitted to the mouth and neck as described above, the closure cannot be released from the mouth and neck unless the holding bridge is destroyed.
前記従来の封緘装置は、瓶の口部を確実に封緘
することができて優れている。
The conventional sealing device described above is excellent in that it can reliably seal the mouth of the bottle.
しかしながら、前記封緘装置は、密封リングの
下部に設けた密封つめの背部は、密封リング下部
のストツパーと、小さな間隙で設けられ、しか
も、密封つめの上部は、保持架橋部で一体に連設
しなければならず、製造が難かしいものである。
また、前記保持架橋部を、折り曲げ易く、かつ破
壊し易く形成することも難かしいことである。 However, in the sealing device, the back of the sealing pawl provided at the bottom of the sealing ring is provided with a small gap from the stopper at the bottom of the sealing ring, and furthermore, the top of the sealing pawl is integrally connected to the stopper at the bottom of the sealing ring. It is difficult to manufacture.
Further, it is also difficult to form the holding bridge portion so that it is easy to bend and break.
本考案は、前記事項に鑑みなされたものであ
り、確実に封緘できる瓶の封緘装置を、製造の容
易な構成とすることを技術的課題とする。 The present invention was devised in view of the above-mentioned matters, and a technical problem is to provide a bottle sealing device that can reliably seal the bottle and has an easy-to-manufacture configuration.
