Abstract: A drinking cup cover includes a cover body and a closure member. The cover body has a cover wall with top and bottom surfaces, a peripheral portion, and a beverage hole formed through the top and bottom surfaces of the cover wall adjacent to the peripheral portion. The cover wall further has a hole-defining periphery that defines the beverage hole. The closure member includes a tab part, a depressible part, and an engaging part. The tab part is connected to the hole-defining periphery such that the closure member is movable relative to the cover body between a sipping position and a non-sipping position. The depressible part protrudes upwardly from the tab part and is operable to move the tab part downwardly from the non-sipping position to the sipping position. The engaging part is formed on one end of the depressible part opposite to tab part to engage the hole-defining periphery.
