A nozzle with lateral spray includes a longitudinal bore with an open first end at a proximal end of the body of the nozzle and a dead second end in a distal portion of the body of the nozzle; a recess defined within a lateral wall of the body of the nozzle, which has a bottom and side walls extending perpendicularly to the longitudinal axis of the body; and a lateral bore that fluidly connects the longitudinal bore to an opening in the recess and has a diameter smaller than the diameter of the longitudinal bore. A nozzle according to the invention provides a lateral spray that is stronger and better focused than nozzles according to the prior art.

A manifold assembly (600) of a spraying apparatus (400), for example for treating plant matter, for coupling the spraying apparatus to a reservoir of liquid concentrate comprising: ⋅a first layer (602) and a second layer (604): ⋅a fluid port (606), located in the second layer (604), for receiving liquid concentrate from a cartridge (200) comprising a reservoir of liquid concentrate; ⋅a fluid inlet (608), located in the first layer (602), for receiving water from the spraying apparatus (400); and ⋅a fluid outlet (610), located in the first layer (602), for outputting a mixture of water and liquid concentrate to the spraying apparatus (400); wherein the manifold assembly (600) comprises a flow path between the fluid inlet (608) and the fluid outlet (610), and wherein the flow path between the fluid inlet (608) and the fluid outlet (610) includes a mixing section (612) fluidly connected to the fluid port (606) and configured to mix liquid concentrate received from the fluid port (606) with water received at the fluid inlet (608).

A dual chamber bottle includes a doser for mixing and dispensing two liquids. The bottle holds a first bulk liquid in a bulk chamber. The bottle holds a second additive liquid in a cartridge. The first and second liquid are segregated from each other. The doser is provided to dose the additive liquid into the bulk liquid. The second liquid is an additive that enhances a quality of the first liquid. The bulk chamber can be squeezed to dispense the bulk liquid out of the bottle while introducing the additive liquid to the bulk liquid in the process of dispensing.

A spray device includes a converging assembly, a container and a suction pipe. The converging assembly includes a first liquid channel, a second liquid channel, a first air channel and a second air channel. The first liquid channel and the first air channel communicate with an inlet of the second liquid channel. The second air channel communicates with the container. An end of the suction pipe communicates with the inlet of the second liquid channel, and another end is submerged in a solution in the container. When a liquid flows from the first liquid channel to the second liquid channel, air in the first liquid channel is discharged via the first air channel, the solution is sucked to the second liquid channel through the suction pipe, the solution and the liquid are mixed at the inlet of the second liquid channel, and then are sprayed from the second liquid channel.

A system for combining and spraying fluids that includes a principal reservoir for holding a carrier fluid; an electric pump in communication with the principal reservoir; a power source for energizing the pump selectable between a rechargeable 12-volt battery and a 110-volt AC line; at least one auxiliary reservoir for holding an auxiliary fluid to be controllably mixed with carrier fluid being drawn from the principal reservoir; a selector valve for selecting which if any of the auxiliary fluid(s) are to be combined with the carrier fluid; a Venturi tube for combining streams of carrier fluid and selected auxiliary fluid(s) in a predetermined ratio which may be varied as desired; and a spray wand in fluid communication with the Venturi tube for discharging the selected fluids.

A ready-to-use sprayer comprises a container defining an interior compartment for containing a liquid product and having a pin receiver located near the rear portion and an opening located near the front portion, a housing having a main chamber and a grip portion, a nozzle in selective fluid communication with the outlet of the fluid chamber, a pivot switch on the exterior of the housing for selecting a fluid flow condition for the main chamber, and the housing being coupled to the container at the container opening and the pin receiver.

A sprayer head may be removably mounted onto a concentrate tank of a hose end sprayer. The sprayer head may include a valve assembly having a valve body having a first axis of rotation selectively movable between a closed orientation, a wet mode orientation, and a dry mode orientation. A metering plate may include a first annular series of spaced-apart flow-metering holes with each successive respective flow-metering hole has an increasing hole diameter adapted to withdraw a selectively adjustable amount of a concentrate from the concentrate tank when the valve body is in either the wet mode orientation or the dry mode orientation. The metering plate has a second axis of rotation which is non-coaxial with the first axis of rotation.
