Abstract

一种用于饮料易拉罐的密封瓶盖,盖口内径与易拉罐的外圆紧配合盖底内有一环形凹槽与易拉罐的罐口凸缘紧配合,盖口内有一锁扣环。本实用新型结构简单,使用方便,密封可靠,可使大量的易拉罐在饮料用完后作为其他用途,如旅游茶杯、烫牛奶替代碗及冷饮冰箱制冰块用具等,以达到废物利用。

Description

本实用新型涉及一种密封的瓶盖,特别是涉及一种用于饮料易拉罐的密封瓶盖。
在现有技术中所用的密封瓶盖往往是瓶口与瓶盖为螺纹旋合,然后在瓶盖底衬上一个橡皮圈,以达到密封,其使用不方便。对于瓶口无螺纹的瓶盖,则仅靠瓶盖口的内圜与瓶口外径紧配合以求密封,但往往不能达到可靠的密封。对于饮料易拉罐,尚无密封瓶盖。
本实用新型的目的在于提供一种用于饮料易拉罐的、使用方便、结构简单且能可靠密封的瓶盖。
为达到上述目的,本实用新型的技术方案是:瓶盖的盖口内径与易拉罐的外圆紧配合。其特点是:瓶盖内底部有一环形凹槽与易拉罐的罐口凸缘紧配合,瓶盖的盖口内有一锁扣环。当瓶盖压入易拉罐口后,由于有锁扣环卡住易拉罐口凸缘,瓶盖不易脱落。瓶盖内底部的环形凹槽与易拉罐口凸缘紧配合,则在罐口凸缘的内径和外径处各形成一个密封环,加上瓶盖盖口内径与易拉罐外径的紧配合形成的密封环,共有三道密封环,形成曲径式密封,所以密封可靠。
从上述的瓶盖结构可以看出本实用新型具有显著优点:由于易拉罐大批量生产,尺寸恒定统一,可以成批量相应制造本瓶盖以配用,其结构简单,使用方便,密封可靠,从而可以使大量的易拉罐在饮料用完后作为其它用途,如旅游茶杯、冰箱制冰块用具等,以达到废物利用。
下面将结合附图对本实用新型的一个最佳实施方案作详细说明。
图1是本实用新型实施方案的结构示意图。(上图为半剖正视图,下图为顶视图)
图2是本实用新型使用状态的半剖面图。
参见图1和图2,本瓶盖的盖口内径6与易拉罐的外圆紧配合,瓶盖内底部有一环形凹槽3与易拉罐的罐口凸缘紧配合,瓶盖的盖口内有一锁扣环5。环形凹槽3是由瓶盖内底部的一个凸环2与瓶盖侧壁4所构成。采用凸环2以构成环形凹槽3,是利用凸环2的柔性以改善环形凹槽3的弹性,使其密封性能更佳。瓶盖内底中心部分1下凹至与易拉罐的内凹的上端面接触,这样的设计能使瓶盖外型更富有立体感,并增加底面刚性。本瓶盖宜用软塑料为材料注塑成型。
用完饮料的易拉罐,可用锉刀将其凸缘的上端略为锉掉一层,则易拉罐的上端面就自然脱落,然后配上本瓶盖,即可作茶杯或其他用途。
