A dispenser valve structure for use in combination with a container for dispensing liquids under pressure, in the form of whipping and shaving creams and the like, in which the container includes a closure having an opening therethrough. The dispenser valve structure has a resilient tubular plug extending through said opening and has a flange engaging the undersurface of said closure and an annular outwardly extending shoulder above said flange, with the underside of said shoulder engaging the container closure to secure the plug to the closure. The plug is provided with a valve seat on its inner side and the plug has a tubular portion which has an exterior annular recess or groove and in which the separate nozzle which fits over the plug has an inwardly extending annular member or ring which engages the groove in the plug to secure the nozzle to the plug. The outer or upper end of the nozzle is slotted to form finger-like tips. The dispenser valve structure has a stem positioned within the tubular plug with the stem being provided at its inner end with a valve head adapted to engage the valve seat of the plug. The stem has a deflector which deflects the discharged cream radially through the slotted finger-like tip end of the nozzle.
