Abstract

一种断扣瓶盖,其瓶盖内壁带有螺纹,螺纹为凸 起的断扣,在瓶盖内部从端口延伸到端底,本实用新 型在使用时不会使瓶内的气压升高,封盖后不易跑气 和泄露,适合于机械化生产。

Description

本实用新型属于一种瓶盖。
目前市场上所用密封液体、固体的瓶盖,其内壁均采用螺纹,在灌装过程中向瓶内压入过量气体,会使灌装后的容器发生跑气、泄露,同时也给灌装生产带来困难。
本实用新型的目的在于克服上述已知技术的不足,从而提供一种灌装时不会产生过量气体的瓶盖。
本实用新型的目的是通过如下方式实现的:
该瓶盖(1)内壁带有螺纹(2),其中:螺纹为凸起的断扣,在瓶盖(1)内部从端口延伸到端底。
在灌装时,瓶内气体从断扣间隙排出,当瓶盖旋到底端时,依靠密封垫将瓶盖密封。
本实用新型与现有技术相比,在灌装封盖时不会使瓶内气压升高,封盖后不易跑气、泄露,适合于机械化生产。
下面结合附图和实施例对本实用新型作进一步描述:
图1是本实用新型正视图
图2是图1的A-A剖视图
在图2中:(1)瓶盖;(2)螺纹。
实施例:瓶盖材料为塑料,螺纹采用双头,断扣处间隙从上至下以直线为最佳,牙距为1~10mm,瓶盖内径为
10~100mm,螺纹每圈为5~20处断扣,间距相等,封盖时应先垫入密封垫置于盖底端,当瓶盖拧紧时密封瓶体。
