An improved liquid sprayer assembly for connection to a container (which preferably includes two liquid storage compartments) has a housing that includes a container mount having an underside with at least one structure that is operably interposed with corresponding structure on a neck portion of the container such that the container mount is fixed in a predetermined orientation relative to the container. A cap locks the container mount to the neck portion of the container. Preferably, the at least one structure of the container mount comprises a pair of wedge-shaped wall structures together with a plurality of wall structures that extend in a directional substantially parallel to the central axis of the mount/neck. The wedge-shaped wall structures are radially disposed opposite one another about the central axis of the container mount/neck and fit within wedge-shaped voids defined by the neck portion of the container. The plurality of wall structures are operably disposed adjacent corresponding surfaces defined by the neck portion of the container. Preferably, the sprayer employs a hose end connector as well as a venturi tube for aspirating liquid from the container. Preferably, a diverter mechanism, which is mounted within the housing, selectively couples the liquid storage compartment(s) of the container to the inlet port of the venturi tube, and a flow control valve controls the flow of pressurized liquid supplied from the hose end into the venturi tube.

A liquid sprayer according to claim 1, wherein: said cap is rotatable about the central axis relative to said container mount and has an internal thread that interfaces to an external thread on the neck portion of the at least one container. 5. A liquid sprayer according to claim 1, wherein: said housing is elongate with a longitudinal axis that is oriented substantially orthogonal relative to the central axis. 6. A liquid sprayer according to claim 1, wherein: said at least structure of the container mount comprises a plurality of wall structures that are operably disposed adjacent corresponding surfaces defined by the neck portion of the at least one container. 7. A liquid sprayer according to claim 6, wherein: the neck portion of the at least one container comprises a base portion having a top surface with a half-circle section and a truncated half-circle section extending therefrom, wherein said plurality of wall structures of said container mount are operably disposed adjacent to said top surface in areas adjacent said truncated half-circle section. 8. A liquid sprayer according to claim 1, wherein: said diverter mechanism comprises a second tubular structure that surrounds said first tubular structure. 9. A liquid sprayer according to claim 8, further comprising: a grip selector mounted on one end of the housing opposite said hose connector. 10. A liquid sprayer according to claim 9, wherein: said grip selector, said first tubular structure, and said second tubular structure are rotatable within said housing, whereby different rotation positions selectively couple zero, one or both of the two liquid storage compartments of the container to the port of said first tubular structure. 11. A liquid sprayer according to claim 1, further comprising: a flow control valve for controlling the flow of pressurized liquid supplied from the hose end into the duct of said first tubular structure. 12. A liquid sprayer according to claim 11, wherein: said flow control valve comprises a semi-hemispherical ball with a through-hole therethrough, said ball rotatable about a transverse axis relative to the duct. 13. A liquid sprayer according to claim 1, wherein: the housing comprises venting means for venting the at least one container. 14. A liquid sprayer comprising: at least one container with first and second liquid storage compartments and a neck portion; a housing having a container mount for connection to said at least one container, said container mount having an underside with at least one structure that is operably interposed with corresponding structure on the neck portion such that said container mount is fixed in a predetermined orientation relative to the at least one container; a cap, separate and distinct from said container mount and operably coupled to said container mount, for locking said container mount to the neck portion of the at least one container; a hose connector, operably coupled to the housing, for connection to a hose end that supplies a source of pressurized liquid; a first tubular structure, mounted within or integral to said housing, having a duct through which flows pressurized liquid supplied from the hose end, wherein the duct has a portion that necks down and then enlarges at a junction with a port downstream from the junction, wherein the port is in fluid communication with said container for aspirating liquid therefrom into the flow of liquid supplied from the hose end and passing through the duct, and a diverter mechanism, mounted within or integral to said housing, that selectively couples zero, one or both of the two liquid storage compartments of said container to the port of said first tubular structure; wherein, the neck portion of the at least one container comprises a central axis, and the at least one structure of the container mount and the corresponding structure of the neck portion extend along a direction substantially parallel to the central axis; and the at least one structure of the container mount further comprises a pair of wedge shaded wall structures that are radially disposed opposite one another about the central axis, wherein said wedge shaped structures fit within wedge-shaped voids defined by said neck portion of said at least one container. 15.
