Abstract:
1. A method for flowing a liquid on a surface, the method comprising: supplying the liquid from a first port of an applicator device to one end of a flow path of the device; applying to the liquid a first port pressure via the first port; receiving the liquid from the other end of the flow path in a second port of the device; applying to the liquid via the second port a second port pressure different to the first port pressure; promoting, via the difference between the first and second port pressures, flow of the liquid from the first port to the second port via the flow path in response to the flow path being located proximal to the surface and the liquid therein contacting the surface; and, drawing, via the first and second port pressures, the liquid towards at least the second port in response to withdrawal of the flow path from the surface.
