Abstract

本实用新型公开了一种双层杯,包括内层杯壁和外层杯壁,内外两层在杯口处汇接,其特征在于:外层杯壁在杯口处有一向外的凸台,内层杯壁向外延伸卷边,包住外层杯壁的凸台,并在该凸台的下端面与其融合。在外层杯壁的上方,与内层杯壁之间,置有一密封圈。本实用新型的两层之间结合牢固,密封性很好。

Description

双层杯
技术领域
本实用新型属于日用器具领域,更具体地,涉及一种杯子,特别是一种双层杯。
背景技术
双层杯是久已有之的一种杯子,其杯壁有内外两层,一般内层为金属,外层为透明材质。采用这种结构,一方面可在内外层间插入各类图案,使得杯子较为美观;另一方面内外层间有空气相隔,热传导较差,当杯子内装有热水时,也不至于烫到使用者。现有的双层杯,是在杯口汇接处将两层融合,这种结合方式不够牢固,受到震动、摔打时易脱落,特别是内外层的热膨胀系数通常是相差较大的,受热时更易松开、脱落;即使不脱落,内外层之间有了缝隙之后,其防水性就变差,夹层很易进水。
发明内容
本实用新型要解决的是双层杯结合不可靠的问题,提供一种更牢固、密封性更好的双层杯。
为完成以上目的,本实用新型采用的技术方案是这样的:双层杯,包括内层杯壁和外层杯壁,内外两层在杯口处汇接,其特征在于:外层杯壁在杯口处有一向外的凸台,内层杯壁向外延伸卷边,包住外层杯壁的凸台,并在该凸台的下端面与其融合。
进一步地,在外层杯壁的上方,与内层杯壁之间,置有一密封圈。
内层杯壁为金属材料,外层杯壁为塑料。
本实用新型将内层拉伸卷边与外层融合,不仅加大了接触面积,也丰富了内外层的受力方向,采用这种结构后,不管在哪个方向受力,内外层都不会脱开;在内外层间置入密封圈后,提高了夹层的防水性,也由于密封圈本身的弹性,进一步增加了内外层结合的紧密度。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
参见附图。本实施例的双层杯有外层杯壁1和内层杯壁2,内层杯壁2为不锈钢,外层杯壁1为透明塑料,两层在杯口处汇接;外层杯壁1在杯口处壁厚明显增加,形成一向外的凸台3;内层杯壁2在杯口处向外延伸卷边,包住凸台3,其边缘4延伸至凸台3的下端面;在凸台3的上方,与内层杯壁之间,置有一密封圈,以提高其密封性。

Claims (3)
