Abstract
A dispenser and a method of delivering an ingredient from a dispenser are disclosed. The dispenser includes a valve assembly including a mounting cup, one or more gaskets, a valve seat, a spring, a housing, and a dip tube. The dispenser container is partly filled with activated carbon, or another adsorbent, and the carrier gas is at a pressure of at least 4 barg, so as to generate a high velocity gas stream, and an ingredient for dispensing is contained in an ingredient containing reservoir. The ingredient containing reservoir is operatively connected to the dispenser container and the dip tube via a first tube and a second tube.

1-21. (canceled)
A dispenser comprising:
- a dispenser container filled with a dispensing carrier gas fitted with a valve assembly, the valve assembly including:
- i) a mounting cup;
- ii) one or more gaskets;
- iii) a valve seat;
- iv) a spring;
- v) a housing;
- and
- vi) a dip tube;
- the dispenser container is partly filled with activated carbon, or another adsorbent, and the carrier gas is at a pressure of at least 4 barg, so as to generate a high velocity gas stream, and an ingredient for dispensing is contained in an ingredient containing reservoir, and
- the ingredient containing reservoir is operatively connected to the dispenser container and the dip tube via a first tube and a second tube such that on actuation of the valve assembly the ingredient and the carrier dispensing gas travel along the first tube and the second tube respectively, and mix in the valve assembly before exiting the dispenser container via an actuator spray nozzle to an environment or subject;
- or
- the carrier dispensing gas travels along the second tube into the ingredient containing reservoir and carries the ingredient along the first tube where they mix in the valve assembly before exiting the dispenser container via the actuator spray nozzle to an environment or subject.
A method of delivering an ingredient from a dispenser, comprising:
- providing a dispenser container filled with a dispensing carrier gas fitted with a valve assembly, the valve assembly including a mounting cup, one or more gaskets, a valve seat, a spring, a housing, and a dip tube;
- wherein the ingredient containing reservoir is operatively connected to the dispenser container and the dip tube via a first tube and a second tube;
- releasing the ingredient from the ingredient containing reservoir under pressure together with the dispensing carrier gas which is at a pressure of at least 4 barg so as to generate a high velocity gas stream, and which is also released on actuation of the valve assembly, wherein the ingredient and the carrier dispensing gas travel along the first tube and the second tube respectively, and mix in the valve assembly before exiting the dispenser container via an actuator spray nozzle to an environment or subject.
A valve assembly for a dispenser comprising:
- i) a mounting cup;
- ii) one or more gaskets;
- iii) a valve seat;
- iv) a spring;
- v) a housing;
- and
- vi) a dip tube that divides into at least two tubes seated within a dispenser container,
- a first tube, seated within the dispenser, is connected to an ingredient containing reservoir, allowing the ingredient to be dispensed on actuation of the valve, and a second tube includes a frit or filter to prevent activated carbon passing into the tube when a pressurised dispensing carrier gas which is at a pressure of at least 4 barg so as to generate a high velocity gas stream is released.
A valve assembly for a dispenser comprising:
- i) a mounting cup;
- ii) one or more gaskets;
- iii) a valve seat;
- iv) a spring;
- v) a housing;
- and
- vi) a dip tube;
- wherein the dip tube is connected to an ingredient containing reservoir via a lid including a first connector and a second connector, the first connector connecting a first tube that connects the valve assembly to the ingredient containing reservoir, and the second connector connects a second tube including a frit or filter that prevents activated carbon passing into the second tube to the ingredient containing reservoir, to permit a pressurised dispensing carrier gas that is at a pressure of at least 4 barg so as to generate a high velocity gas stream to drive the ingredient out of the ingredient containing reservoir upon actuation.
