Description

便携式可扩容水杯
技术领域
本实用新型属家用饮水杯,尤其是一种便携式可扩容水杯。 
背景技术
水是生命的摇篮,人们每天都离不开水的滋润涵养,因此喝水用的水杯自然也就成了日常家居中不可缺少的用品,为了适应外出、旅游,加有盖子密封的各式各样的水杯也就不断涌现出来,方便了人们外出装水解渴的需求。然而有一点令人不太满意的是,目前的此类杯子,尽管大小、形态、材料不尽相同,性价亦互有长短,但都无法改变杯子的容量,所能盛水亦是固定的,要想多装只能用大杯,外出带大杯又显得不便。 
发明内容
对上面提到的水杯之不足,本实用新型的目的就是为了提供一种能按需要改变杯子的容量,携带方便,同时仍保持加盖杯子特点的水杯。 
具体是这样实现的:可扩容水杯由杯体、杯底及杯盖几部分组成,其中主要特征是杯体分内、外两层,内层套在外层中,并可上下抽动,两层共用一个杯底及杯盖; 
上述水杯的内层下端外壁及上口外壁均有凸螺纹; 
上述水杯的内层下底部及上口部分别有一道防溢垫圈; 
上述水杯的外层上口部内壁和杯盖内壁都分别有凹螺纹; 
平时内层筒套于外层,需扩容时抽出内层,让内层下端外壁的凸螺纹与外层口部内壁的凹螺纹旋绞紧,即可达到扩容目的,不用时扭松内层压下到底便又恢复原状,携带方便,能随意改变水杯的容量,宜于外出使用。 
附图说明
下面是本实用新型的结构附图: 
图1为内层立体示意图; 
图2为外层纵剖面图; 
图3为扩容后的结构示意图; 
具体实施方式
下面给出实施例并结合附图作进一步说明: 
如图1所示中空圆筒状的内层1,其下端外壁有凸螺纹2和防溢圈3,上口部有凸螺纹4和防溢圈5;如图2所示外层6的上口内壁有凹螺纹7,下为杯底8;如图3所示杯内层1上合有杯盖9。
