Abstract

减压杯,属于饮水的容器,主要解决杯盖打开问题。包括杯体和与杯体螺纹密封连接的杯盖,其特征在于,所述的杯盖有双层构成,外表面有一小孔。杯盖有一套减压系统。减压系统由橡胶垫和弹簧构成。杯体内气压降低时,减压系统打开,空气进入杯体,使杯盖容易打开。

Description

减压杯
技术领域
本实用新型涉及到一种饮水的杯子。
背景技术
现在使用的杯子当装满热水拧紧盖子,水冷却后,盖子紧压在杯口,不易打开。
发明内容
为了解决上述问题,本实用新型的目的是提供一种杯盖能够自动减压的水杯。
本实用新型的技术方案是:该减压杯,包括杯体和与杯体螺纹密封连接的杯盖,其特征在于,所述的杯盖有双层构成,杯盖上有一对通孔,一套置弹簧的阀杆位于下层通孔内,阀杆的顶部与上层通孔配合。
本实用新型的有益效果是:通常情况下减压系统不工作,当杯体内气压降低时,减压系统打开,空气进入杯体,使杯盖容易打开。
附图说明
图为本实用新型的实施例结构示意图。
图中;1杯体、2杯盖、3上孔、4阀杆、5弹簧。
具体实施方式
减压杯,包括杯体1和与杯体螺纹密封连接的杯盖2,其特征在于,所述的杯盖2有双层构成,杯盖2上有一对通孔,一套置弹簧5的阀杆4位于下层通孔内,阀杆4的顶部与上孔3配合,可实现上孔3的封闭与打开。
当杯子充满热水拧紧盖子,水冷却后,杯内气压降低,弹簧借助大气压力被压缩,阀门打开,空气进入杯中,使杯中内外压力相等,杯盖易被打开。
