Abstract: A sachet (1) having walls of flexible material is disclosed. The walls are joined so as to form an impermeable seal, thereby defining a cavity within the sachet (1). A conduit (2) passing through the seal and having inner and outer ends is disposed with the inner end within the cavity and the outer end outside the sachet (1) such that the cavity is in fluid communication, via the conduit, with the outside of the sachet. The cavity contains a volume of liquid (8) in use, and the conduit (2) is adapted to prevent the liquid (8) flowing from the cavity without the application of an additional stimulus, irrespective of the orientation of the sachet (1).
Abstract: An electrostatic spraying device comprises a capillary spray electrode having a spraying end, a reference electrode, and a reservoir in fluid communication with the spray electrode. In use, the electrodes are connected across a generator in order to establish an electric field between the electrodes and cause fluid in the reservoir to be sprayed from the spray electrode. The spray electrode has a focus that defines a point at which the electric field is focussed on the spraying end.
Abstract: A dispenser system comprising a reservoir, a closure device for controlling the flow of liquid from the reservoir, and a housing to which the reservoir is attached is disclosed. The reservoir is movable relative to the housing from a storage position in which the closure device prevents liquid flowing from the reservoir to a dispensing position in which the closure device allows liquid to flow from the reservoir. The housing comprises an activation device which on movement of the reservoir from the storage position to the dispensing position causes the closure device to allow the liquid to flow from the reservoir.
