A housing has a dispensing outlet () and contains: a liquid supplier () for supplying liquid containing at least one volatile component to a liquid outlet (); an electric field provider () for causing liquid issuing from the liquid outlet to provide electrically charged droplets from which at least a part of the at least one volatile component evaporates to produce vapour; a collection receptacle () for collecting electrically charged droplets to inhibit the electrically charged droplets from passing through the dispensing outlet; an attraction electrode () for attracting electrically charged droplets into the collection receptacle (); and a flow director () for directing vapour away from the collection receptacle () and towards the dispensing outlet ().

Aroma dispensing device

Consumable or dissolvable tablets are manufactured by supplying a liquid containing a biodissolvable carrier to an outlet; establishing an electric field between the outlet and a support surface to cause liquid issuing from the outlet to form at least one fiber or fibrils of the biodissolvable carrier which fiber or fibrils deposit(s) onto the surface to form a fiber web or mat; separating the web or mat into a plurality of individual tablets; and incorporating at least one active ingredient on or in the tablets.

Method and apparatus for manufacturing dissolvable tablets

A method of providing a droplet spray, includes supplying a liquid polymer formulation within which substantially inert particulate material is suspended to an outlet and subjecting liquid issuing from the outlet to an electric field that causes the liquid to break up into droplets.

Liquid formations for electrohydrodymanic spraying containing polymer and suspended particles

Methods are described of delivering biological material, which methods include the steps of providing a liquid formulation containing the biological material, supplying the liquid formulation to an outlet and subjecting liquid issuing from the outlet to an electrical field thereby causing electrohydrodynamic processing of the liquid without denaturing the biological material. In one example, the liquid formulation is provided by removing salts from a formulation containing biological material that does not denature in alcohol and then adding an alcohol to the formulation before supplying the liquid formulation to the outlet. An acid may be added to the liquid formulation before supplying the liquid formulation to the outlet.

Devices and formulations

An inhaler has a housing containing a chamber ( ) providing a reservoir ( ) for liquid providing an active ingredient to be supplied to a liquid outlet ( ). First and second electrodes are spaced apart ( and ) with the first electrode being spaced apart ( and ) with the first electrode being provided at or adjacent the liquid outlet ( ). A voltage supply ( ) is activated in response to air flowing through an air inlet ( ) of the housing to provide a potential difference between the first and second electrodes ( and ) to create an electric field for causing comminution of liquid issuing from the liquid supply outlet ( ) to produce a stream of electrically charged comminuted matter for supply to the nasal passages of a user via an outlet ( ) of the housing.
