A moulded valve cup for an aerosol valve assembly which includes means for connecting the interior of the cup to the exterior thereof, the means comprising a flange at the upper end of the cup, a counter bore within the cup substantially equal to the thickness of the flange and an aperture extending through the flange in a direction parallel with the main axis of the cup and opening radially inwardly to the periphery of the counterbore over the full thickness of the flange. This construction avoids moulding problems of the prior art wherein the apertures are formed by separate movable pins in the moulding tool, which are expensive and are prone to leave vestigial flashes at their junction with a central core pin. |
