Abstract
Liquid dispensing apparatus comprises a tubular casing having at one other end an inlet nozzle connectable to a source of gas under pressure and at its end an outlet nozzle having an orifice in communication with an expansion chamber bounded by sides which diverge away from or converge towards the orifice. The liquid dispensing apparatus containing a pen-like liquid source having an absorbent nib at least partially within the casing with the nib within or in close proximity to the nozzle orifice. The pen-like source may comprise a felt-tipped pen.
Claims10
Liquid dispensing apparatus which comprises a tubular casing having at one end an inlet nozzle connectable to a pump providing a source of gas under pressure and at its other end an outlet nozzle having an orifice defining a smallest throat diameter, the orifice being in communication with an expansion body, the expansion body bounded by sides which, considered in the direction of gas flow, diverge away from the smallest throat diameter of the orifice, and means for locating a liquid source including an elongate body and an absorbent nib at least partially within the casing with the nib extending at least partially within the smallest throat diameter.
