Abstract

一种保温杯杯盖,主要解决普通保温杯杯盖难以打开的问题。它包括杯盖本体,其特征是,所述的杯盖本体内侧有一橡胶膜层,橡胶膜层与杯盖本体共同形成一个密封的减压腔,所述的杯盖本体上端面有一带内螺纹的通孔,通孔内旋合一带螺纹的塞子。打开杯盖前先松塞子,由于橡胶膜层有弹性会向下凹,使杯内的气压回复到标准气压,同时橡胶膜层不会漏水,增强了保温杯的密封性能。

Description

保温杯杯盖
技术领域
本实用新型涉及一种保温杯附属部件,具体地说是一种保温杯杯盖。
背景技术
当保温杯长时间盛满热水,保温杯的盖子不容易被打开,原因是当保温杯中的热水水温降低后,杯内的气压就会降低,与外界环境形成压力差,使杯子盖难以被打开,这个问题对小孩子来说尤其突出。
实用新型内容
本实用新型的目的在于克服现有技术的不足而提供一种保温杯杯盖,可以方便的打开杯盖,省时省力。
本实用新型解决其技术问题所采取的技术方案是:该保温杯杯盖,包括杯盖本体,其特征是,所述的杯盖本体内侧有一橡胶膜层,橡胶膜层与杯盖本体共同形成一个密封的减压腔,所述的杯盖本体上端面有一带内螺纹的通孔,通孔内旋合一带螺纹的塞子。
本实用新型的有益效果是:打开杯盖前先松塞子,由于橡胶膜层有弹性会向下凹,使杯内的气压回复到标准气压;同时橡胶膜层不会漏水,增强了保温杯的密封性能。
附图说明
图1为本实用新型的剖面示意图;
图中:1杯盖本体,2橡胶膜层,3减压腔,4塞子。
具体实施方式
如图1所示,该保温杯杯盖,包括杯盖本体1,其特征是,所述的杯盖本体1内侧有一橡胶膜层2,橡胶膜层与杯盖本体1共同形成一个密封的减压腔3,所述的杯盖本体1上端面有一内螺纹的通孔,通孔配一带螺纹的塞子4。
一般状态下,橡胶膜层起到一个保温密封的作用,当需要打开杯盖时,下旋转塞子,让外界的空气进入减压舱,在压力差的作用下,橡胶膜层会向下凹,杯内的气压升高,这样便容易将被盖打开。
