Abstract

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.

Abstract

This invention relates to improvements in a delivery technology referred to in the industry as bag-on-valve (BOV) technology and to a dispenser for use with a modified valve assembly, not necessarily using the bag, and in which a dispensing aerial gas is released. The dispenser, and method of delivery, utilise a dispensing aerial carrier gas, (a gas composed of air or one of the natural components of air), which is absent of an adsorbent, typically activated carbon. The dispenser (20) comprises a dispenser container (90) filled with a dispensing aerial carrier gas (140) fitted with a valve assembly (10). On actuation the ingredient (100) travels out via a first fitment (182) of a dividing boss (80) and the dispensing aerial carrier gas travels out via a second fitment (184) of a dividing boss (80), 0 via a reducer insert (300) which manages respective flow rates of the dispensing aerial carrier gas and ingredient allowing the ingredient and dispensing aerial carrier gas to mix within a mixing chamber (280) of an actuator assembly (15) such that substantial atomisation or aerosolization of the ingredient occurs on discharge when exiting the dispenser container (90) via an actuator spray nozzle (220) to an environment or subject at an average flow rate of 0.4g/s or greater.

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.
