These are the components that allow the fine mist sprayer to turn a liquid stream into a mist:
The cap is usually made of transparent PP plastic and is used as a dust cover and safety cap to prevent accidental dispensing of products by the actuator.
This is what you push down to dispense the product, and unlike the lotion pump actuator, it has internal components to create a specific atomization pattern of the product. The consumer pushes down to spray the product from the bottle. Some actuators also have a locking function to prevent accidental assignment.
This tiny part is where the liquid flows to create a mist-like pattern and is installed on the outside of the actuator. This is where the product leaves the sprayer.
The cap holds the entire assembly together and secures it to the bottle. It is usually made of PP plastic and has many different finishes and design options, including but not limited to a metal case.
This is why the cap is sealed on the bottle to prevent leakage. Different products and chemical compositions require different material choices, so this is the most important part of the test to ensure compatibility.
This mechanism actually combines many different components into one, including the piston, valve stem, seal, spring, and housing cover. This is why the product is transferred from the bottle to the actuator. Pressing down on the actuator will pull the product out of the dip tube, through the piston towards the actuator, and then through the insert from there.
This is the long plastic tube that enters the sprayer from the bottom of the bottle. Unlike the thicker lotion pump dip tube, the sprayer dip tube is thinner, usually slightly curved to reach the bottom so that all the contents of the product can be dispensed.
