Abstract

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 disengages the valve stem from the valve seal to allow fluid to flow into the stem inlet and out of the stem outlet. The valve stem displaces the metering member as the valve stem moves. Movement of the valve stem relative to the metering member prevents flow of fluid into the stem inlet and out of the stem outlet. 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.

4 . A dispensing system as recited in claim 2 , further comprising a plurality of the guide flanges.

5 . A dispensing system as recited in claim 1 , further comprising at least one guide flange, where the at least one guide flange stops the metering member in the second metering position.

6 . A dispensing system as recited in claim 1 , further comprising at least one guide flange, where the at least one guide flange:

guides the valve stem for movement between the first stem position and the second stem position through the intermediate stem position relative to the valve seal; and

stops the metering member in the second metering position.

7 . A dispensing system as recited in claim 1 , in which:

the metering member is detachably attached to the valve stem as the valve stem moves from the first stem position to the intermediate stem position such that movement of the valve stem causes the metering member to move from the first metering position to the second metering position; and

the metering member is detached from the valve stem as the valve stem moves from the intermediate stem position to the second stem position such that the valve stem moves relative to the metering member and the metering member stays in the second metering position.

8 . A dispensing system as recited in claim 7 , further comprising at least one guide flange, where the at least one guide flange:

guides the valve stem for movement between the first stem position and the second stem position through the intermediate stem position relative to the valve seal; and

stops the metering member in the second metering position.

9 . 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.

10 . A method as recited in claim 9 , further comprising the step of, after the valve stem carries the metering member back into the first metering position, allowing the valve spring to force the valve stem back into the first stem position.

11 . A method as recited in claim 9 , further comprising the step of arranging least one guide flange to guide the valve stem for movement between the first stem position and the second stem position through the intermediate stem position relative to the valve seal.

12 . A method as recited in claim 9 , further comprising the step of arranging at least one guide flange to stop the metering member in the second metering position.

13 . A method as recited in claim 9 , further comprising the step of arranging least one guide flange to:

guide the valve stem for movement between the first stem position and the second stem position through the intermediate stem position relative to the valve seal; and

to stop the metering member in the second metering position.

14 . A method as recited in claim 9 , further comprising the steps of:

detachably attaching the metering member to the valve stem as the valve stem moves from the first stem position to the intermediate stem position such that movement of the valve stem causes the metering member to move from the first metering position to the second metering position; and

detaching the metering member from the valve stem as the valve stem moves from the intermediate stem position to the second stem position such that the valve stem moves relative to the metering member and the metering member stays in the second metering position.

15 . A method as recited in claim 14 , further comprising the step of arranging at least one guide flange to guide the valve stem for movement between the first stem position and the second stem position through the intermediate stem position relative to the valve seal.

16 . A method as recited in claim 14 , further comprising the step of arranging at least one guide flange to stop the metering member in the second metering position.

17 . A method as recited in claim 14 , further comprising the step of arranging at least one guide flange to:
