A liquid dispenser which comprises: a rigid container defining a volume for said liquid, said container having a pouring orifice and an aperture; a flexible, gas impermeable follower disposed in said container for defining a variable volume, said follower having an opening at one end; and a valve secured in said aperture in said container with said open end of said follower secured about said valve for providing communication between ambient atmosphere and said variable volume when said valve is open, said valve moving to said open position when a pressure differential is established between ambient atmosphere and said container volume as liquid is dispensed through said orifice, whereupon ambient gas enters and expands said follower solely by virtue of said pressure differential, said valve moving to a closed position when liquid dispensing ceases and said pressure differential diminishes for substantially retaining said gas in said follower, whereby said gas filled follower substantially fills the container volume vacated by dispensed liquid, thereby minimizng the headspace in said container even after the contents thereof are partially dispensed.
