Abstract
A dispenser and a method of delivering an ingredient from a dispenser are disclosed. The dispenser includes a dispenser container and a valve assembly comprising a valve connected to the dispenser container. The dispenser container is partly filled with activated carbon or another adsorbent and a dispensing carrier gas. An ingredient is contained in an ingredient containing reservoir. The valve assembly includes a component comprising a tube, an upper end of which is in operative communication with an actuator spray nozzle, and a lower end of which divides into first and second fitments which receive respectively first and second tubes. The first tube is connected to the ingredient containing reservoir. The second tube includes a frit or filter to prevent the activated carbon passing into the second tube when the pressurized dispensing carrier gas is released.
