摘要:
A apparatus for delivering a predetermined quantity of content from a pressurized container includes a dispensing assembly which sits on the container and connects with an upper portion of a valve stem of the valve assembly, wherein the dispensing assembly includes a) an actuator cap having a discharge passage, which is open or obstructed and wherein the actuator cap acts as a metering chamber in combination with b) an adaptor which fits inside the cap and also snuggly engages the valve stem. The cap fits snuggly over the adjuster to define a metering chamber which depending on its position can close off the metered chamber or open it to the dispensing conduit\nozzle. When the cap is depressed it pushes down on the adjuster which depresses the valve. The chamber fills, but nothing is released until the upstroke.

An outlet assembly for an aerosol assembly comprises a valve assembly and a metering member. The valve assembly comprises a valve housing, a valve stem defining a stem inlet and a stem outlet, a valve spring, and a valve seal. Movement of the valve stem from a first stem position to an intermediate stem position disengages the valve stem from the valve seal such that fluid is allowed to flow into the stem inlet and out of the stem outlet. The valve stem displaces the metering member from a first metering position to a second metering position as the valve stem moves from the first stem position to the intermediate stem position. Movement of the valve stem causes the valve stem to move relative to the metering member such that the metering member covers the stem inlet to prevent flow of fluid into the stem inlet and out of the stem outlet. The spring member displaces the valve stem such that the valve stem carries the metering member while the metering member covers the stem inlet to prevent flow of fluid into the stem inlet and out of the stem outlet.

A metering chamber (7) is fixed by its upper end to the portion of a valve body (9) located, in the mounted state, inside the vial, an inlet passage being provided contacting the inside of the vial and the metering chamber and an outlet passage contacting the metering chamber and the outside of the valve. The inlet passage can be closed when the valve element (4) is in the open position and the outlet passage can be closed when the valve element (4) is in the closed position. In addition, the valve element can be moved beyond the open position into a third position, called short-circuit position, a third passage, called short-circuit passage, being provided to contact the inside of the vial and the outside of the valve. The short-circuit passage can be closed when the valve element (4) is in the closed position or the open position.

An aerosol device for dispensing texture material for matching existing accoustical ceiling texture. The device comprises a container, a valve assembly, a dispensing nozzle, a hardenable material, and pressurized inert gas as a propelling mechanism. The hardenable material and pressurized inert gas are placed into the container. When the valve assembly is opened, the the inert gas forces the hardenable material out of the container through the dispensing nozzle. The dispensing nozzle diverts at least a portion of the hardenable material exiting the container to develop a spray suitable for the application of the hardenable material onto the ceiling surface being textured. The hardenable material preferably comprises at least water, filler, binder, and polystyrene particles. The inert gas is preferably nitrogen.

The axial passage (15) of the central foot (14) of the membrane support (13) comprises a valve seat (14) applied on the extremity of a hollow stem (5) of the continuous valve to fill the measuring cap (11) during the phase of measuring the amount of material to be dispensed, and which moves away from the extremity of the hollow stem (5) to put in communication the measuring cap and the port (21) during the discharge phase.
