A dispensing closure for dispensing a flowable product from a squeeze-type product container comprising: a closure body having an upper deck, an exit orifice, a flow conduit in communication with said exit orifice and depending downwardly from said upper deck to provide a flow path from an entrance orifice at a lower end thereof to said exit orifice, and an inner skirt depending directly downwardly from said upper deck of the closure body and being configured to attach to a product container; a cup-shaped measuring reservoir having an upper peripheral edge received in snap-fitting engagement with a mounting rim on a lower surface of said upper deck, said mounting rim encircling said flow conduit, said measuring reservoir having a plurality of flow ports adjacent said upper peripheral edge, and further having a bottom wall, said measuring reservoir filling with a measured dose of flowable product through said flow ports when said container is inverted; a cup-shaped piston valve having a bottom wall and a valve stem extending within the cup-shaped piston valve and extending upwardly from said bottom wall in a direction toward said flow conduit, said piston valve being slidably movable within the measuring reservoir between an open position wherein said valve stem is spaced from a valve seat formed at said entrance orifice of said flow conduit whereby flowable product can enter said measuring reservoir through said flow ports and exit through said flow conduit, and a closed position wherein said valve stem is in mating engagement with said valve seat closing said flow conduit, said piston valve being movable from said open position to said closed position to dispense said measured dose of product responsive to pressure within said container induced by squeezing said container; and a coil spring encircling said flow conduit and said valve stem and captured between said lower surface of said upper deck and said bottom wall of said piston valve, said spring normally biasing the piston valve to said open position. a closure body having an upper deck, an exit orifice, a flow conduit in communication with said exit orifice and depending downwardly from said upper deck to provide a flow path from an entrance orifice at a lower end thereof to said exit orifice, and an inner skirt depending directly downwardly from said upper deck of the closure body and being configured to attach to a product container; a cup-shaped measuring reservoir having an upper peripheral edge received in snap-fitting engagement with a mounting rim on a lower surface of said upper deck, said mounting rim encircling said flow conduit, said measuring reservoir having a plurality of flow ports adjacent said upper peripheral edge, and further having a bottom wall, said measuring reservoir filling with a measured dose of flowable product through said flow ports when said container is inverted; a cup-shaped piston valve having a bottom wall and a valve stem extending within the cup-shaped piston valve and extending upwardly from said bottom wall in a direction toward said flow conduit, said piston valve being slidably movable within the measuring reservoir between an open position wherein said valve stem is spaced from a valve seat formed at said entrance orifice of said flow conduit whereby flowable product can enter said measuring reservoir through said flow ports and exit through said flow conduit, and a closed position wherein said valve stem is in mating engagement with said valve seat closing said flow conduit, said piston valve being movable from said open position to said closed position to dispense said measured dose of product responsive to pressure within said container induced by squeezing said container; and a coil spring encircling said flow conduit and said valve stem and captured between said lower surface of said upper deck and said bottom wall of said piston valve, said spring normally biasing the piston valve to said open position.
