1. A fluid applicator apparatus comprising:
- a fluid reservoir designed to hold fluid to be applied to a surface, the fluid reservoir having a neck opening at one end;
a fluid applicator means designed to apply fluid to the surface; and
fluid transfer means for effecting a metered transfer of the fluid from the fluid reservoir to said fluid applicator means, the fluid transfer means being located upon and within the neck opening of the fluid reservoir, the fluid applicator means when being utilized to apply liquid to the surface being in fluid communication with the fluid transfer means;
the fluid transfer means further comprising an extensible and retractable spring-biased discharge means having a first and second fluid inlet and, spaced from both first and second fluid inlets, a fluid outlet, the first fluid inlet being located adjacent to the fluid discharge means and the second fluid inlet being located toward the distal end of a hollow tube member attached to and in fluid communication with the fluid discharge means;
the fluid applicator means further comprising in apertured applicator cap, having located on its outer surface a dispersing means, the aperture of the applicator cap being designed to receive the fluid outlet of the fluid discharge means, the applicator cap being moveable relating to the fluid reservoir in such a way that a predetermine force imposed on the applicator cap causes the fluid discharge means to be retracted and then extended, which in turn causes fluid to be transferred from the fluid reservoir to the dispersing means.

Abstract
A fluid applicator apparatus having a container, an applicator cap, a mechanism for allowing a pre-determined volume of fluid to be pumped from the container into a pad on the applicator cap and a protective overcap. The pumping mechanism has an attached ball-check valve arrangement which allows fluid transfer from either an upright or an essentially inverted position.

10. A method of controlling an insect population comprising:
-
manipulating a fluid applicator apparatus comprising; a fluid reservoir designed to hold fluid to be applied, having a neck opening at one end; a fluid applicator means; and fluid transfer means for effecting a metered transfer of the fluid from the fluid reservoir to said fluid applicator means, the fluid transfer means being located upon and within the neck opening of the fluid reservoir; the fluid transfer means further comprising an extensible and retractable spring-biased fluid discharge means having a first and a second fluid inlet and, spaced from both first and a second fluid inlets, a fluid outlet, the first fluid inlet being located adjacent to the fluid discharge means and the second fluid inlet being located toward the distal end of a hollow tube member attached to and in fluid communication with the fluid discharge means; the fluid applicator means further comprising an apertured applicator cap, having located on its outer surface a dispersing means, the aperture of the applicator cap being designed to receive the fluid outlet of the fluid discharge means, the applicator cap being moveable relative to the fluid reservoir in such a way that a predetermine force imposed on the applicator cap causes the fluid discharge means to be retracted and then extended, which in turn causes fluid to be transferred from the fluid reservoir to the dispersing means;
the pumping mechanism further including a ball check valve, the ball check valve having a ball moveable in a channel so that, when the apparatus is in an upright position and fluid is drawn into the pumping mechanism through the second inlet, the first inlet is closed off, and, when the apparatus is in an inverted position, the second fluid inlet is exposed, and fluid is drawn into the pumping mechanism through the second inlet in such a way that the insecticide solution contained in the apparatus is transferred from the fluid reservoir to the dispersing means located on the applicator cap;pressing the dispersing means against a portion of a surface; and moving the applicator in such a direction that a strip of insecticide solution is applied upon the surface, applying further increments of pressure as necessary to effect the transfer of more insecticide solution if necessary to cover the area desired, thus applying an effective amount of the insecticide solution to the surface to produce the desired kill effect.
