Abstract: An adjustable nozzle is attachable to the end of a garden hose and is also attachable to a separate product container, for example, a bottle containing a garden fertilizer or a bottle containing a cleaning soap concentrate. The adjustable nozzle receives a flow of water from the garden hose and dispenses a product from the container attached to the nozzle. The nozzle has a simplified construction with a reduced number of component parts and the operation of the nozzle is simplified yet enables a user to selectively discharge a flow of water or a mixture of water and product from the nozzle, to control the ratio of water to product when the nozzle is employed in dispensing the mixture of water and product, and to direct the discharge as a stream or disperse the discharge in an upwardly or downwardly directed fanned spray pattern.

Abstract: A trigger sprayer valve assembly that has a conical flange that controls the flow of liquid in a downstream direction through a liquid passage of the trigger sprayer. The valve is constructed with an elongate stem or shaft that facilities the assembly of the valve into the trigger sprayer and a positioning plug that solely holds the valve in a centered position in the liquid passage of the trigger sprayer.

Abstract: A nozzle assembly including a nozzle member, a cap member, a spinner and a foam tube. The cap member is rotationally mounted on the nozzle member and may be rotated from an “off-position” to a “foam-position” with continued rotation bringing the cap member to a “spray-position” and then to a second “foam-position” and then to the “off-position.” Rotation of the cap member drives foam tube from a retracted position to an extended position extending forward of the nozzle member when the cap member is in the “foam-position.” The spinner rotates to atomize liquid flowing through the assembly.
