<p>A spray gun comprising a container (2) and a spray head (6) fitted to the container, the spray head (6) being provided with a filling passage (35) through which the container (2) can be filled. The spray gun may comprise a dosing device (16) which is adapted to eject a measured dose of, for example, herbicide into the filling passage (35). The end of the filling passage (35) may comprise a curved rigid tube (8) which extends from the spray head (6) to the base of the container (2) and supports a dip tube (18) of flexible material through which fluid in the container (2) can be drawn into the pumping device (14). The rigid tube (8) may be rotatable relative to the pump housing (6) and the container (2), so that the spray gun may be adapted for spraying at different orientations.</p> |
