Description

防伪防漏瓶盖
本实用新型涉及一种防伪防漏瓶盖。
现有常用的防伪瓶盖有两种,一是由带有开裂线的盖体和内置的软性垫片组成,盖体在开裂线的上部与瓶口旋接在一起,下部即抱紧在瓶颈定位凸环上,启盖时旋开盖体,开裂线断开,不可修复,以此起到防伪作用,但该盖体结构简单,造价低,易被破坏后从新换一盖体。另一种是在盖体内侧设一刀口,在开盖时,将瓶口或瓶颈刻破,使瓶子不能重复使用,达到防伪之目的,但该防伪盖在装瓶时工艺要求较高。
本实用新型旨在设计一种带有启封识别标志和防回灌及防漏功能的瓶盖。
本实用新型的任务是这样实现的,防伪瓶盖包括一带开裂线的盖体,其结构特征是用于塞紧瓶口的单向阀塞内腔置有活动小珠,单向阀塞外部套接有带孔的限位套,单向阀塞与限位套间设有活动内盖,限位套卡接在盖套上,盖套下部内侧设有定位环,限位套外旋接有一带内凸柱的旋盖,旋盖的内凸柱通过限位套的中孔顶住活动内盖的上部,带开裂线的盖体,套在旋盖及盖套的外侧,在开裂线下侧的盖体上向内设有卡环,卡住盖套下沿,盖体与旋盖靠相配合的摩擦牙定位。装瓶时,单向阀塞塞进瓶内,盖上活动内盖,将卡接有限位套的盖套扣紧瓶口,旋上旋盖,使活动内盖盖严单向阀塞的出口,起防漏,最后将带开裂线的盖体套上即可。
本实用新型设计合理,单向阀塞的采用可有效防止液体回灌,而且配有限位套,使液体沿曲线路径流出,也不易被用针头类工具回灌回瓶,盖体上的开裂线起到启封识别标志,旋盖与活动内盖的配合可有效地防漏,并保证瓶内有良好的气密性。
下面结合具体图例对本实用新型做进一步说明:
附图为防伪防漏瓶盖剖面示意图
参照附图,单向阀塞1的内腔设置有二粒玻璃小珠2,上面的一粒小珠2起重力作用,使下面小珠2与单向阀塞1内腔锥口接触更好,若用钢珠只用一粒即可,限位套3上设有便于液体流出的小孔4,限位套3与盖套11卡接在一起,装瓶时是做为一整体,单向阀塞1与限位套3之间设有活动内盖5,限位套3外旋接有一带凸柱的旋盖7,靠相配合的螺牙8旋接在一起,并起启盖导向,旋盖7上的凸柱9通过限位套3的中孔顶住活动内盖5,使其盖严单向阀塞的出口,起到防漏和密封作用,同时也有防回灌及限制小珠2的活动范围,盖套11下部内侧设有定位环10,定位环10成倒钩状,用于卡住瓶颈上的凸环,带开裂线的盖体6套在旋盖7及盖套11的外侧,盖体6与旋盖7间靠相配合的摩擦牙12定位,便于一次启盖,在开裂线下侧的盖体上向内设有卡环14,卡住盖套11下沿定位,单向阀塞1外侧设有弹性环裙13,起紧瓶口作用。
以上涉及的配件除小珠外,其余均可注塑而成,盖体上的开裂线可由模具一次成型,也可切割成型,或由双体焊接成型。本防伪防漏瓶盖配件较多,其模具成本较高,从经济角度上也能限制一些人为的防造。
