  • Patent number: 10414552
    Abstract: A drinking cup lid, comprising: a center cover portion; a rib ring formed at the external circumferential edge of the center cover portion, the rib ring having a drinking recess, the external edge of the drinking recess being open while an insertion opening is disposed at the internal edge thereof, the bottom surface of the drinking recess being provided with a drinking opening; a vent hole formed in the center cover portion or in the rib ring; a snap ring portion formed at the external circumferential edge of the rib ring for a snap fit to the drinking cup; and a plug connected by a flexible strip in a hanging way to the external circumferential edge of the snap ring portion, the plug having a plug portion, a hand-held portion and an insert portion. Before use, the insert portion of the plug is fitted first into the insertion opening. Thereafter, the plug portion is fitted to the drinking opening. In this way, the laborious plug-and-pull problem of the conventional splash proof plug is resolved.
