APPARATUS FOR APPLYING LIQUID TO A SURFACE

摘要

An apparatus for applying liquid to a surface includes an outer vessel (26) an inner liquid container (1) which is housed within the outer vessel (26) and which is substantially closed but includes an inlet for pressurized gas and a separate outlet for liquid, and means (37) for supplying pressurized gas to the container. An interface of the container (1) and the outer vessel (26) is sealed around the inlet for pressurized gas whereby in use a region of the space between the outer vessel (26) and the inner container (1) is not pressurized. The unpressurized region of the outer vessel (26) is vented. An applicator (42) is connected via a length of flexible tube to the liquid outlet.
