Abstract
A container for dispensing liquids includes a body member and a closure therefor. The closure includes a cap in the form of a plastic moulding having an outlet and a control valve within the cap. The control valve is a one piece plastic moulding having a diaphragm portion and a nose portion. The nose portion normally seals the outlet but is displaceable therefrom on distortion of the diaphragm portion resulting from pressurization of the interior of the body member and whereby liquid is dispensed through the outlet. The cap further includes an annular seating for the control valve which is of hollow, open-ended, generally cylindrical shape, the diameter of which is on the same order to that of the diaphragm portion of the control valve.
