A valve of the tilt opening type for pressurised dispensing containers comprises a mounting cap (112) having a cylindrical portion and a frusto-conical portion. A valve stem (114) extending through the valve cup has a surrounding sealing sleeve (115) which includes a frusto-conical skirt portion (112) which surrounds the corresponding portion of the valve cup. The valve is opened by tilting the valve stem thereby unsealing apertures (118) in the valve stem and the shape of the sealing sleeve prevents it lifting off from the mounting cup. |
