Description

杯盖 技术领域
本申请有关于一种杯盖。
背景技术
一般饮品的容器(例如塑料杯或纸杯)多借由一塑料杯盖扣接于该容器的开口，避免该容器内的液体洒漏以便于携带。现有的塑料杯盖除了设有饮用口外，另穿设有一透气流道，当该容器用于容置热饮时可供热气排出该容器外部，避免该容器内部的压力过高而造成危险。
现有的塑料杯盖的透气流道虽可供热气排出该容器而减压，排出的热气接触外部的冷空气后却会于该透气流道的外周凝结成液体而溢流，该透气流道朝外开放亦可能导致该容器内的饮品受污染或渗漏。为解决前述问题，市面上已发展出借由一封盖盖设于该塑料杯盖的饮口并于该封盖穿设一微小的透气流道的方式，以达到排气、防渗漏的效果。然而，该封盖上的透气流道于行进间仍会有渗漏问题，且该封盖无法稳定组接于该塑料杯盖而容易脱落，存在亟待改善的缺弊。
因此，有必要提供一种新颖且具有进步性的杯盖，以解决上述的问题。

作为本申请的一个实施例，其中该本体包括一第一卡接部，该盖体另包括一能够与该第一卡接部相卡接的第二卡接部。
作为本申请的一个实施例，其中该遮蔽部包括若干设有该若干透气流道的挡板，至少一该挡板径向抵接于该孔壁。
作为本申请的一个实施例，其中沿该轴向观之，至少一该挡板遮蔽该贯孔的径向尺寸的至少1/2。
作为本申请的一个实施例，其中该若干挡板包括面向该至少一连通道的一上表面及一下表面，于该轴向上，该孔壁的一延伸高度不小于该上表面与该下表面的间距。
