Hose nozzle that distributes chemical?

Not sure if this is the right sub, but I'm sure you all know your hose nozzles. I'm looking for a nozzle that can be used as regular for hosing, but if you turn a knob it can distribute chemical via an attached container.

Basically the same as the picture below, but a more permanent model that doesn't break after a few goes.
