An atomizing pump dispenser which includes a valve member (11) having a flattened top so that the diameter of the sealing area (14) in the outlet is increased substantially. A recess (21) within the valve member (11) is modified to provide conical ball sealing portions (27) tapered at predetermined angles to provide a tight seal between the ball (23) and the valve member (11). The innermost end of an inner hollow part (15) of the valve member (11) is a reduced diameter portion (18) such that the initial movement of the valve member (11) is easier. This in effect, tricks the user's finger by easing the initiation of movement of the actuator so as to give the feel of free movement. The inner part (15) of the valve member (11) is provided with a molded-in slotted protrusion (16) for breaking the seal between the valve member (11) and a flexible annular seal, thus alleviating the creation of the vacuum caused by the seal between the ball (23) and the ball seat.
