APPARATUS FOR SPRAYING LIQUIDS, AND DISPOSABLE CONTAINERS AND LINERS SUITABLE FOR USE THEREWITH

摘要

A spray gun ( 1 ) has a fluid reservoir ( 11 ) with a removable liner ( 13 ) received in a container ( 12 ) having a detachable lid ( 15 ). The liner ( 13 ), which may be thermo/vacuum-formed from a planar material, has a shape that corresponds to and is a close fit within the interior of the container ( 12 ) and collapses as fluid is withdrawn from within the liner ( 13 ) during operation of the spray gun ( 1 ). The lid ( 15 ) has an outlet ( 16 ) connected to an inlet on the spray gun ( 1 ) for transfer of liquid from the reservoir ( 11 ) to the spray gun ( 1 ) and the container ( 12 ) has a vent ( 12 A) in the base end for admitting air between the container ( 12 ) and the liner ( 13 ) as liquid is withdrawn from within the liner ( 13 ).
