ABSTRACT:
A spray pump package capable of delivering two or more different predetermined spray patterns or spray characteristics through two or more different spray orifices, but at a liquid application amount per unit of area being treated which is optimum for the particular spray orifice selected rather than a compromise between two extremes. The predetermined spray patterns from which the end user may select may differ by any desired spray pattern or characteristic, including but not limited to: the cone angle of the spray; the width of the spray pattern; the average size of the particles in the spray; the amount of particle size deviation from the average; etc. The packages are provided with structure for automatically adjusting the maximum available pump stroke so as to optimize the maximum amount of product which can be delivered on each complete pump stroke for whichever orifice is selected by the end user. In a particularly preferred embodiment, the package employs a positive displacement pump which is self priming regardless of stroke length.
