1. A lubricant applicator for a ball hitch comprising:
(a) a diaphragm assembly including:
(i) a diaphragm member having a non-permeable top surface, the top surface having an inner facing surface and an outer facing surface, a central region of the inner facing surface being coated with lubricant that is releasable from the inner facing surface when pressed against an external surface, and
(ii) a peripheral sidewall; and
(b) a hollow support structure having a peripheral sidewall, the diaphragm assembly being positionally secured within the hollow support structure to provide a unitary structure, the peripheral sidewalls of the diaphragm assembly and the hollow support structure being adjacent each other, and
wherein the lubricant-coated central region of the diaphragm member is configured to deform and partially encapsulate at least an upper portion of the ball hitch when the lubricant applicator is centered over the ball hitch and pressed down over the ball hitch to allow release and transfer of at least a portion of the lubricant from the inner facing surface of the diaphragm member to the at least upper portion of the ball hitch.
