杯盖
本技术涉及杯具领域,尤其是一种杯盖。
技术介绍
中国专利申请号CN201110003667.3的专利技术公开了一种杯盖,可供盖合于具有扣唇的杯体上,该杯盖包括有一顶部、一环侧板与一至多个卡扣部,该环侧板自该顶部之周缘向下延伸,该卡扣部设于该环侧板内,该卡扣部包括有一片体,其中片体与环侧板之间形成有一压缩空间,片体与环侧板之间并具有弹性,使片体可弹性地向压缩空间压缩,借此,本专利技术盖合于杯体时,可利用杯体的扣唇推抵片体,当顶部盖合于扣唇后,片体即弹性复位,使扣唇被夹抵于片体与顶部之间,而可提高杯盖与杯体之间的结合强度。传统的塑杯的杯盖存在杯体叠放时易松脱的不足,因此,设计一种叠放时不会松脱的叠放不会松脱的杯盖,成为亟待解决的问题。
技术实现思路
本技术的目的是为了克服目前的塑杯的杯盖存在杯体叠放时易松脱的不足,提供一种叠放时不会松脱的叠放不会松脱的杯盖。一种杯盖,包括:盖圈,与盖圈下端连接的盖底;所述的盖底设有:大端位于盖底上端的锥台形圆凸块和与锥台形圆凸块同轴的凸环;盖底下端设有:大端位于盖底下端且与锥台形圆凸块相对的锥台形圆沉孔和与凸环相对的凹环;锥台形圆凸块的锥度与锥台形圆沉孔的锥度相同;锥台形圆凸块小端的直径小于锥台形圆沉孔大端的直径且大于锥台形圆沉孔小端的直径;凸环的横截面形状为大端位于盖底上端的等腰梯形;凹环的横截面形状为大端位于盖底下端的等腰梯形;凸环小端的宽度小于凹环大端的宽度且大于凹环小端的宽度。叠放不会松脱的杯盖叠放时,锥台形圆凸块嵌入锥台形圆沉孔中,凸环嵌入凹环中;该叠放不会松脱的杯盖叠放时叠放时不会松脱。作为优选,所述的盖底上端设有若 ...
