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.

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.

A dispenser includes a dispenser container and a valve assembly including a valve connected to the dispenser container. The dispenser container is at least partially filled with activated carbon and/or another adsorbent and a dispensing carrier gas. An ingredient is contained in an ingredient containing reservoir. The valve assembly further includes an upper end of which is in operative communication with an actuator spray nozzle, and a lower end connected to the ingredient containing reservoir, and a means to prevent the activated carbon and/or another adsorbent from passing into the valve assembly when the pressurised dispensing carrier gas is released. On actuation, the dispensing carrier gas is released together with the ingredient, and the ingredient and dispensing carrier gas mix before exiting the dispenser.

A dispenser for dispensing material under pressure that includes a canister defining a chamber and having an opening therein extending from the chamber to an exterior of the canister. A first portion of the chamber adjacent the opening is configured to contain a material for dispensing through the opening. A second portion of the chamber is configured to contain a solution. An enclosed reservoir is provided in the second portion of the chamber, the enclosed reservoir configured to initially contain a catalyst and to be subsequently opened to release at least a portion of the catalyst.
