Lotion pumps are used to dispense viscous fluids and are widely used in products such as liquid soaps, hand sanitizers, shampoos and facial cleansers. Although there are many Plastic Lotion Pump Bottle available, the basic mechanism remains the same.

We will delve into the main components of the lotion pump and understand their functions.

Key components of lotion pump
A lotion pump usually consists of the following six components:

Actuator
The head of the lotion pump is usually made of polypropylene. As a pump head, when pressed from above, it performs the main task of discharging material from the lotion pump reservoir.

shut down
The device performs the most important task, fixing the entire material on the neck of the lotion pump. Ensuring the safety of the entire assembly is of utmost importance.

Outer gasket
It helps prevent material from leaking from the bottle area. Usually made of low-density polyethylene or rubber, usually friction fit in the closure.

housing
The housing unit assembles all the parts of the lotion pump in one place. In addition to this, it is also used as a transfer container to send material from the dip tube to the actuator.

Internal housing components
The internal housing components include balls, springs, pistons and stems, and the internal housing compartments. Specifications may vary from manufacturer to manufacturer.

Dip tube
It is made of polypropylene and is a long tube extending from the head of the lotion pump to the bottom.

The working principle of lotion pump
Step 1-Synchronous operation with the principle of the suction device, working against gravity. When the head is pressed, the friction generated by the inner wall forces the piston to open.

Step 2-The piston moves when the actuator is depressed, which in turn compresses the spring. It exerts upward pressure in the dip tube. In addition, the material in the dip tube reaches the lotion pump chamber.

Step 3-Once the actuator is released, the ball will drop, preventing the flow of material and making sure it does not return to the bottom of the lotion pump.

The fourth step-when the fluid in the body fluid storage cavity is full, press the nozzle again to discharge the fluid.
