Abstract

一种自体密封瓶盖,内部带有螺纹扣,在瓶盖内 的盖底端上带有一个圆形的密封垫,密封垫底部与盖 底端连为一体,顶部向圆心收拢,内部形成中空,本实 用新型可实现对瓶体自行密封,结构简单,降低了加 工成本,并可回收利用。

Description

本实用新型属于一种瓶盖。
目前,普通瓶盖需要使用橡胶密封垫密封,或在盖外包漆,这种密封使得灌装工艺复杂,加工成本高,密封件无法重复使用。
本实用新型的目的在于克服上述已知技术存在的不足,从而提供一种结构简单,可自行密封的瓶盖。
本实用新型的目的是通过如下方式实现的:
该瓶盖(1)内带有螺纹扣,其中:在瓶盖(1)内的盖底端(2)上带有一个圆形的密封垫(3),密封垫(3)底部与盖底端(2)连为一体,顶部向圆心收拢,内部形成中空。
本实用新型与现有技术相比具有如下优点:瓶盖密封时,当瓶口接触到密封垫时,可对密封垫实行挤压,实现密封,瓶盖与密封垫制成一体,便于加工生产,结构简单,同时简化了灌装工艺,降低了成本,瓶盖还可回收利用。
下面结合附图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)盖底端;(3)密封垫。
实施例:瓶盖材料为塑料,注塑一次成型,密封垫沿盖底内沿向圆心收拢形成锥面,与轴心夹角为70~85°,内部形成中空是为了增加垫的弹性,增强密封效果,为防止瓶盖在密封垫反作用力下松动,内螺纹采用小间距双头螺纹,以瓶盖内径50mm计,齿间距为3~5mm。
