The utility model relates to a novel double-layer drinking cup, which comprises an outer cup, an inner cup and a cup cover. The upper and outer sides of the outer cup are provided with external threads of the outer cup, and the upper part of the inner cup is provided with a flanging, which extends outward from the outer wall of the inner cup, and then downward. The inner cup is provided with internal threads of the inner cup, and the outer threads of the inner cup are located on the outer wall of the inner cup. Above, the inner cup is set on the inner side of the outer cup, and the outer thread of the outer cup is connected with the inner thread of the inner cup. The lower part of the inner wall of the cup cap is connected with the inner thread of the inner cup. The inner thread of the cup cap is connected with the outer thread of the inner cup. The top of the cup cap is provided with an upward protruding nozzle, the outlet nozzle is connected with the inner cup, and an air vent is arranged on the cup cap. The advantages of the utility model are: through flanging design, water can be prevented from entering between the inner cup and the outer cup during cleaning, and the debris generated by the inner cup and the outer cup during screwing can be prevented from falling into the inner cup, which is safe and reliable.
【技术实现步骤摘要】
新型双层饮水杯
本技术涉及饮水杯,特别是新型双层饮水杯。
技术介绍
在日常生活中,人们喝水、喝茶都要用到水杯,目前市场上主要有单层水杯和双层水杯两种。单层水杯有玻璃水杯、塑料水杯、金属水杯、陶瓷水杯以及一次性纸杯等,玻璃水杯和陶瓷水杯易于摔碎,安全性较差;塑料水杯常含有聚丙乙烯或PVC聚氯乙烯等有毒的化学物质,不利于人体健康;另外,单层水杯还具有一个共同的缺点:盛放热水时,热水将热量传导给杯壁,从而使杯壁很烫,不便于拿取;因此,很多单层水杯的杯壁上都设计有专供人手握的杯把,然而杯把的设计又使单层水杯的体积变大,外出携带就显得很不方便。双层水杯的内胆与杯体的隔热设计,不仅使杯体拿起来不烫手,还对茶水有保温作用,从而深受广大消费者的欢迎。传统的双层水杯的外杯与内胆为不可拆卸的一体式结构,但是其生产难度高,成本大,后来双层水杯的外杯与内胆出现可拆卸结构,其生产工艺难度大幅降低,内胆与外杯通常通过螺纹配合连接,但是外杯与内胆在配合连接时,旋拧过程中所产生的碎屑容易掉进内胆内,而且外杯与内胆的螺纹配合连接段总会存在一些缝隙,水容易从该缝隙中进入外杯与内胆之间,导致外杯内壁上的图案纸张受潮。
技术实现思路
本技术的目的在于克服现有技术的缺点,提供一种新型双层饮水杯,通过翻边设计,可防止内杯与外杯之间在清洗时进水,同时可防止内杯与外杯在旋拧时产生的碎屑掉入内杯内,安全可靠。本技术的目的通过以下技术方案来实现:新型双层饮水杯,包括外杯、内杯和杯盖,所述外杯的上部外侧设有外杯外螺纹,所述内杯的上部设有翻边,所述翻边自内杯的外壁向外延伸,然后再向下延伸,在所述翻边向下延伸的内壁上设有 ...
