A ball dispenser is formed by a cylindrical housing or tube with a piston slidable therein and biased to a dispensing end of the tube. A cap is connected by a bridging member the tube and projects over the axial center line of the cylinder and is formed with a concave spherical shape to receive the end of a ball contained within thedispenser. The dispenser is symmetrical on opposite sides of a central plane and an assess opening of mouth is provided adjacent to the cap through the side of the tube opposite the bridging section. The mouth is symmetrical on opposite sides of the plane and has its maximum opening at the central plane. The periphery of the mouth is defined by substantially V-shaped sides on each side of the plane with the bottom of the V shapes adjacent to the bridging section. The front edge or lip of the cap i.e. at the plane overlying the mouth is closer to the cylindrical axis then the spherical radius of the ball to be dispensed so that the ball may be retained in the cap by the spring pressure on the piston and yet be easily withdrawn therefrom through the mouth or balls may be slid through the mouth with a rotating around the front lip of the cap.
