Aerosol spray texture apparatus for a particulate containing material

A method of dispensing material from an aerosol assembly comprising the steps of:

• providing a valve housing;
• providing a valve stem defining a stem inlet and a stem outlet;
• providing a valve spring;
• providing a valve seal;
• arranging the valve stem such that
• the valve stem engages the valve seal when the valve stem is in a first stem position to prevent flow of fluid into the stem inlet and out of the stem outlet, and
• the valve seal supports the valve stem for movement between the first stem position and a second stem position through an intermediate stem position relative to the valve seal;
• supporting a metering member for movement between a first metering position and a second metering position relative to the valve housing;
• moving the valve stem from the first stem position to the intermediate stem position to disengage the valve stem from the valve seal such that fluid is allowed to flow into the stem inlet and out of the stem outlet, where movement of the valve stem from the first stem position to the intermediate stem position displaces the metering member from the first metering position to the second metering position;
• and
• arranging the valve spring to force the valve stem from the second stem position to the first stem position such that the valve stem carries the metering member from the second metering position to the first metering position while the metering member covers the stem inlet to prevent flow of fluid into the stem inlet and out of the stem outlet.

A dispensing system for dispensing material, the dispensing system comprising:

• a valve assembly comprising
• a valve housing,
• a plurality of the guide flanges extending from the valve housing,
• a valve stem defining a stem inlet and a stem outlet,
• a valve spring, and
• a valve seal;
• and
• a metering member supported for movement between a first metering position and a second metering position;
• whereby
• the valve seal and the plurality of guide flanges support the valve stem such that
• the valve stem is capable of moving between a first stem position and a second stem position through an intermediate stem position,
• the valve stem engages the valve seal when the valve stem is in the first stem position to prevent flow of fluid into the stem inlet and out of the stem outlet, and
• the at least one guide flange stops the metering member in the second metering position;
• movement of the valve stem from the first stem position to the 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, where the valve stem carries the metering member from the first metering position to the second metering position as valve stem moves from the first stem position to the intermediate stem position;
• movement of the valve stem from the intermediate stem position to the second stem position 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;
• and
• the valve spring displaces the valve stem from the second stem position towards the first stem position such that the valve stem carries the metering member from the second metering position to the first metering position while the metering member covers the stem inlet to prevent flow of fluid into the stem inlet and out of the stem outlet.
