Cup cover having opening means

A cover for a drinking cup, said cover being of the type that has a tab which may be opened for providing a drinking opening, said tab being hinged to the remainder of the cup at a medial portion of the cover and extending to the periphery of the cover, the improvement comprising a sump adjacent to the position at which the tab is hinged to the cover for collecting liquid from the top of the cover, said sump being so positioned as to allow liquid from the sump to drain into the drinking opening when the cup is tilted for drinking therefrom.

A cover for a drinking cup of the type having a peripheral rib formed by inner and outer upwardly projecting peripheral walls forming a peripheral recess on the under side of the cover, the outer wall of the rib being inclined inwardly and being spaced from the inner wall to allow the walls to frictionally engage the rim of a cup, in which a tab is formed in the cover by score lines extending radially outwardly from a hinge portion connecting the tab to the remainder of the cover, the outer end of the tab including a segment of the peripheral rib, whereby said tab may be pivoted to an open position about said hinge portion, and latch means on the opposite side of the hinge from the tab positioned and dimensioned for cooperating with the inwardly inclined outer wall of the portion of the rib at the end of the tab to hold the tab in the open position, and for retaining the walls of the portion of the peripheral rib on the end of the tab in substantially their original spacing so as to enable them to securely engage the rim of the cup when the tab is re-closed.
