Abstract: A fluid dispensing cap has a trigger vertically operable to actuate a valve. The cap has a window located below the trigger. The window defines a side edge and a bottom edge of the cap. A plate has a tab projecting therefrom. The plate also has a bottom surface with a channel. The plate is disposed in the window. A linking rib connects the plate to the side edge of the cap. The bottom edge is disposed in the channel. Movement of the trigger to actuate the valve is prevented until the plate and tab are affirmatively removed.

Abstract: An aerosol valve with a refill prevention mechanism is provided. The valve has a valve stem disposed in a valve housing that defines an inner chamber. The valve stem has upper passage in an upper portion of the valve stem that is provided with a flexible resilient member. The flexible resilient member is compressed on an orifice or aperture communicating with the housing to create a seal and prevent filling in an open position when pressure in the upper passage is greater than a pressure in the inner chamber. The flexible resilient member is deflected away from the orifice or the aperture when pressure in the upper passage is less than a pressure in the inner chamber to allow dispensing of a product.
