Abstract

本实用新型公开了一种防挥发瓶盖,它包括瓶口(1)和瓶盖(2),在瓶口(1)和瓶盖(2)上设有相互配合的螺纹,在瓶盖(2)内设有密封环(3),密封环(3)的外侧与瓶口(1)内侧相接触,瓶口(1)的内侧为锥面。本实用新型在瓶盖内加装密封环,设计时将密封环的外侧与瓶口内侧相接触,且将两接触面的瓶口面加工为锥面,这样在瓶盖拧紧的过程中,两接触面就会越压越紧,从而达到很好的密封效果,确保瓶内气体不会挥发。

Description

一种防挥发瓶盖
技术领域
本实用新型涉及一种防挥发瓶盖,属于密封容器技术领域。
背景技术
现有容器的密封多是采用螺纹密封或橡胶塞进行密封,但上述密封方式在使用过程中均存在密封性较差的问题,特别是其内存储介质为挥发性液体或固体时,密封性就会更加难以保证。
发明内容
本实用新型要解决的技术问题是:提供一种结构简单、密封性好的防挥发瓶盖,可以克服现有技术的不足。
本实用新型的技术方案是:防挥发瓶盖,它包括瓶口和瓶盖,在瓶口和瓶盖上设有相互配合的螺纹,在瓶盖内设有密封环,密封环的外侧与瓶口内侧相接触,瓶口的内侧为锥面。
瓶口内侧的锥面下端外径大、上端外径小。
与现有技术比较,本实用新型在瓶盖内加装密封环,设计时将密封环的外侧与瓶口内侧相接触,且将两接触面的瓶口面加工为锥面,这样在瓶盖拧紧的过程中,两接触面就会越压越紧,从而达到很好的密封效果,确保瓶内气体不会挥发。
附图说明
图1为本实用新型的一种结构示意图。;
具体实施方式
实施例1:如图1 所示,储存物体的瓶口1和瓶盖2通过相互配合的螺纹相互连接,为增加密封性,在瓶盖2内设有密封环3,密封环3的外侧与瓶口1内侧相接触,且瓶口1的内侧为锥面,瓶口1内侧的锥面下端外径大、上端外径小,这样在拧紧瓶盖2的过程中,密封环3的外侧锥面就会与瓶口1内侧越接触越紧,实现密封。

Claims (2)

1.一种防挥发瓶盖,它包括瓶口(1)和瓶盖(2),在瓶口(1)和瓶盖(2)上设有相互配合的螺纹,其特征在于:在瓶盖(2)内设有密封环(3),密封环(3)的外侧与瓶口(1)内侧相接触,瓶口(1)的内侧为锥面。
2. 根据权利要求1所述的防挥发瓶盖,其特征在于:瓶口(1)内侧的锥面下端外径大、上端外径小。
