Bag on valve technology

A method of delivering an ingredient from a dispenser which is absent of an adsorbent and includes a dispensing aerial carrier gas, the method comprising:

• releasing the ingredient from at least one of a dispenser container and an ingredient containing reservoir under pressure together with the dispensing aerial carrier gas which is also released on actuation of a valve assembly;
• flowing the ingredient and the dispensing aerial carrier gas respectively along a first fitment and a second fitment to a reducer insert and along respectively a reducer aerial carrier gas conduit and a reducer ingredient conduit;
• managing a respective flow rate of the dispensing aerial carrier gas and the ingredient via the reducer aerial carrier gas conduit and the reducer ingredient conduit;
• and
• allowing the ingredient and the dispensing aerial carrier gas to mix within a mixing chamber of an actuator assembly such that at least one of a substantial atomization and a substantial aerosolization of the ingredient occurs on discharge when exiting the dispenser container via an actuator spray nozzle to at least one of an environment and a subject at an average flow rate of at least 0.4 g/s;
• wherein the dispensing aerial carrier gas is carbon dioxide having a pressure of at least 7 barg;
• and
• wherein the ingredient is an aqueous system.

A dispenser, comprising a metering device and a dispenser container filled with a dispensing aerial carrier gas fitted with a valve assembly, the valve assembly including:

• a mounting cup;
• at least one gasket;
• a valve seat;
• a spring;
• a housing;
• and
• a dividing boss including a first fitment and a second fitment;
• wherein the dispenser container is absent of an adsorbent and is at least one of:
• partially filled with an ingredient for dispensing;
• and
• the ingredient for dispensing is contained in an ingredient containing reservoir;
• wherein the first fitment of the dividing boss, along which the ingredient is carried, is connected to at least one of:
• a dip tube;
• and
• a tube and ingredient containing reservoir;
• wherein, on actuation, the ingredient travels out via the first fitment of the dividing boss and the dispensing aerial carrier gas travels out via the second fitment of the dividing boss via a reducer insert which manages respective flow rates of the dispensing aerial carrier gas and the ingredient allowing the ingredient and the dispensing aerial carrier gas to mix within a mixing chamber of an actuator assembly such that at least one of substantial atomization and substantial aerosolization of the ingredient occurs on discharge when exiting the dispenser container via an actuator spray nozzle to at least one of an environment and a subject at an average flow rate of at least 0.4 g/s;
• wherein the dispensing aerial carrier gas is carbon dioxide having a pressure of at least 7 barg;
• wherein the ingredient is an aqueous system;
• and
• wherein the dispenser is absent of at least one of a liquified propellant, a hydrocarbon-based propellant, and a fluorocarbon-based propellant.
