A cap is provided for preventing clogging of a spray nozzle on a container. Structurally, the cap includes a hollow, truncated cone-shaped member with first and second ends. At its first end, the cap defines an orifice dimensioned to selectively receive the spray nozzle to create a fluid-tight seal with the container. At its second end, the cap defines a periphery. Further, the cap includes a panel that has a flat surface bounded by a perimeter that is interconnected to the periphery by an intermediate section. As a result, the cone-shaped member, intermediate section and panel form a fluid chamber. Fluid is positioned in the chamber for movement between a first location where the spray nozzle is submerged and a second location where the fluid is held at a distance from the spray nozzle for removal of the cap from the spray nozzle.
