摘要： A dispensing closure for dispensing flowable product from a squeeze container includes a closure body having an upper deck and a dispensing orifice within the upper deck. A timing piston extends downwardly from the upper deck and is located adjacent to the dispensing orifice. The timing piston is movable between an open position wherein a flared piston neck is spaced from the dispensing orifice, and a closed position wherein the flared piston neck closes off the dispensing orifice. A timing vent within the upper deck is in communication with a piston chamber to allow air to escape the piston chamber. An air intake orifice within the upper deck allows air to enter the piston chamber, and a ball valve structure adjacent the bottom surface of the upper deck cooperates with the air intake orifice to control the flow of air through the air intake orifice.
