A fluid applicator apparatus which may be used for insect control having a container (50), an applicator cap (20), a mechanism (82) for allowing a pre-determined volume of fluid to be pumped from the container (50) into a pad (40) on the applicator cap (20) and a protective overcap (54). A problem exists to control the fluid flow rate to the pad (40) in a vertical position or the opposite inverted position of use of the apparatus. The solution to the problem is providing the pumping mechanism (82) with an attached ball-check valve (94) arrangement which allows fluid transfer from either an upright or an essentially inverted position. |
