A container closure (10, 100, 200, 220, 320) is attached to a container (12) having an opening. The closure (10, 100, 200, 220, 320) includes a tip (40, 240, 340) moveable between an open and a closed position. The tip (40, 240, 340) has an opening (42) adapted to be in fluid communication with the container opening with the tip (40, 240, 340) in the open position, wherein a flow path for contents of the container (12) is defined between the container opening and the tip opening (42) when the tip (40, 240, 340) is in the open position. The tip (40, 240, 340) further includes at least one horizontal seal (50, 54) in the flow path for sealing the closure (10, 100, 200, 220, 320) when the tip ( 40, 240, 340) is in the closed position and at least one vertical seal (52) in the flow path for sealing the closure ( 10, 100, 200, 220, 320) when the tip (40, 240, 340) is in the closed position. The tip (40, 240, 340) may be attached directly to the container (12) and the motion of the tip (40, 240, 340) from the closed to the open position may be stopped directly by the container (12).
