Description

密封防伪瓶盖
本实用新型涉及一种瓶盖,尤其是密封防伪瓶盖。
目前市场上出现的饮料防伪瓶盖都是瓶盖主体与防伪环为一个件,且防伪环内壁平面没有锥度,因而盖与瓶之间存在间隙,密封不严密,细菌易从盖与瓶之间的缝隙进入。又由于这类瓶盖主体的内壁螺纹线是单进丝螺纹线,故需将瓶盖旋转一圈或多圈才能打开或旋紧,所以它使用不太方便。
本实用新型的目的是提供一种密封防伪瓶盖,不仅带有防伪标志,而且能实现二次密封;确保细菌不进入瓶内。
本实用新型的具体方案是:包括带内封塞的瓶盖主体,其特征在于:瓶盖主体的内螺纹线是三进丝螺纹线;在瓶盖主体的下部固接有防盗环,防盗环的上部为卡环,防盗环的下部为锁环,锁环的内壁和卡环的外壁均呈锥形,卡环与锁环之间由连接筋连接。
本实用新型将瓶盖主体的内螺纹线设计成三进丝螺纹线,在启盖或封盖时只需旋转120°就可完全密封。本实用新型将瓶盖分为瓶盖主体和防盗环两部分,可大大减小盖与瓶之间的间隙;将防盗环的锁环内壁设计成向内的锥形面,可使瓶得到第二次密封。第一次密封是瓶盖主体顶面所带的内封塞插入瓶口完成的。
采用上述方案具有防伪功能,使用方便,启闭瓶盖快捷、省力,密闭效果好,可进行二次密封,能保证瓶内饮料干净卫生。
下面结合附图及实施例对本实用新型进一步说明。
图1是本实用新型的主视图;
图2是图1中防盗环2的结构图。
由图1可知:本实用新型由防盗环2和瓶盖主体3组成,其结构特征是:瓶盖主体3的内螺纹线是三进丝螺纹线;在瓶盖主体3的下部固接有防盗环2,防盗环2的上部为卡环5,防盗环2的下部为锁环6,锁环6的内壁和卡环5的外壁均呈锥形,卡环5与锁环6之间由连接筋7连接。本实用新型套装在瓶1上,瓶盖主体3顶面的内封塞4插入瓶口1中,对瓶进行第一次密封。由于锁环6的内壁和卡环5的外壁均呈锥形,因而防盗环2与瓶盖主体3和瓶1的连接非常紧密,防盗环2对瓶进行第二次密封;一但启开瓶盖,防盗环2在连接筋7处断裂,锁环6套在瓶颈上,而卡环5仍保留在瓶盖主体3上。
