A closure for a container that is adapted to hold a fluid for dispensing and has an opening, comprising: (a) a cap member mountable to the container and enclosing the opening, the cap member having a cylindrically walled sleeve forming an outer opening in the cap member, and at least one orifice formed in the sleeve; (b) a movable nozzle valve having a generally cylindrical hollow body disposed for longitudinal movement within the cylindrically walled sleeve between an open position to permit flow of a fluid through said hollow body from the container and a closed position to prevent flow of a fluid through the hollow body, the hollow body having at least one seal member projecting radially outwardly from an exterior surface and engaging the cylindrically walled sleeve, the hollow body having an ear projecting radially outwardly and received in the at least one orifice to define a stop member for limiting movement of the hollow body within the sleeve between the open and closed positions; wherein the cap member has a radially outwardly extending lip formed at the distal end of the sleeve, and wherein the at least one orifice is formed in the sleeve between said outer opening and the lip, the hollow body having a distal end with an inner and outer surface; characterized in that the cylindrically walled sleeve forms the outer opening in the cap member at the proximal end of the sleeve, in that a channel is formed in the lip, the channel defining an inner surface and an outer surface, wherein the distal end of the hollow body nests within the channel when the valve is in the closed position, and the inner surface of the distal end of the hollow body engages said inner surface of the channel and the outer surface of the distal end of the hollow body engages the outer surface of the channel to form a seal between said distal end of the hollow body and the channel. (a) a cap member mountable to the container and enclosing the opening, the cap member having a cylindrically walled sleeve forming an outer opening in the cap member, and at least one orifice formed in the sleeve; (b) a movable nozzle valve having a generally cylindrical hollow body disposed for longitudinal movement within the cylindrically walled sleeve between an open position to permit flow of a fluid through said hollow body from the container and a closed position to prevent flow of a fluid through the hollow body, the hollow body having at least one seal member projecting radially outwardly from an exterior surface and engaging the cylindrically walled sleeve, the hollow body having an ear projecting radially outwardly and received in the at least one orifice to define a stop member for limiting movement of the hollow body within the sleeve between the open and closed positions; wherein the cap member has a radially outwardly extending lip formed at the distal end of the sleeve, and wherein the at least one orifice is formed in the sleeve between said outer opening and the lip, the hollow body having a distal end with an inner and outer surface; characterized in that the cylindrically walled sleeve forms the outer opening in the cap member at the proximal end of the sleeve, in that a channel is formed in the lip, the channel defining an inner surface and an outer surface, wherein the distal end of the hollow body nests within the channel when the valve is in the closed position, and the inner surface of the distal end of the hollow body engages said inner surface of the channel and the outer surface of the distal end of the hollow body engages the outer surface of the channel to form a seal between said distal end of the hollow body and the channel.
