Drinking cover for a beverage container comprising a circular top wall and annular side wall with sealing means on the bottom periphery of the side wall for securing the cover to the upper rim of a beverage container. The top wall is tapered downwardly from front to back and contains an opening. A sealing flap underlies the opening and is attached to the bottom surface of the top wall so that the flap is movable from a closed position to an open position with respect to the opening.

Cover for a beverage container having an annular upper rim, said cover comprising: (a) a circular top wall having a peripheral edge, said edge having a front portion and an opposite rear portion, said top wall having an opening which is near the front portion of said edge and spaced from said edge,

Cover for a beverage container having an annular upper rim, said cover comprising: (a) a circular top wall having a peripheral edge, said edge having a front portion and an opposite rear portion, said top wall having an opening which is near the front portion of said edge and spaced from said edge, (b) an annular side wall which extends downwardly from said edge, the top of said side wall gradually tapering downwardly from said front portion to said rear portion so that the top wall gradually tapers downwardly from said front portion to said rear portion, (c) sealing means on the bottom periphery of the side wall for securing the cover to the rim of the container, and (d) a sealing flap which underlies said opening and which is attached to the inner surface of the top wall, the flap being movable from a closed position in which the flap seals the opening to an open position in which the flap is in a non-sealing relationship with the opening, the top wall being made of a flexible material and the sealing flap being attached to the top wall at a limited area which is spaced from the opening, so that the flap is free to pivot about said limited area to move from said closed position to said open position upon application of downward force against said top wall, wherein the inner surface of the top wall is normally concave, and the flap is sufficiently flexible to conform to the curvature of the said inner surface of the top wall and in contact therewith, so that the flap is parallel with the top wall in said closed position. Cover for a beverage container having an annular upper rim, said cover comprising: (a) a circular top wall which is made of flexible material and which has an annular peripheral edge, said edge having a front portion and an opposite rear portion, said top wall having an opening which is near the front portion of said edge and spaced from said edge, the inner surface of said top wall being axially outwardly curved, (b) an annular side wall which extends downwardly from said edge, (c) sealing means on the bottom periphery of the side wall for securing the cover to the rim of the container, and (d) a sealing flap which unlerlies said opening and which is attached to the said inner surface of the top wall intermediate the front and rear portions, so that the flap is movable from a closed position to an open position relative to the opening, said flap normally occupying said closed position and is movable to said open position upon application of downward pressure on the top wall, said top wall being capable of deflecting axially inwardly upon application of pressure to said top wall adjacent said opening thereby causing said flap to pivot about its location of attachment to said top wall and causing said open position.
