24mm 28mm 30mm 32mm PP Plastic Lotion Pump with Left And Right Rotation for Liquid Soap and Lotion Dispensing

A screw lotion pump is a mechanical, hand-operated dispenser designed for the controlled and hygienic delivery of liquid or viscous products like lotions, soaps, shampoos, and sauces. It consists of two main parts: a pump mechanism housed under an actuator (the button you press) and a screw-on closure that securely attaches to the neck of a bottle.

When the actuator is pressed, it engages a piston within a cylinder. This creates pressure that draws the product up through a dip tube and forces it out through the discharge nozzle. Releasing the actuator allows a spring to reset the piston, priming the pump for the next use. Most models incorporate a sealing gasket and a one-way valve system to prevent leakage and air ingress, ensuring product integrity.

Key advantages include precise dosage control, ease of use with one hand, prevention of contamination, and a clean, modern appearance. They are ubiquitous in personal care, cosmetic, and household packaging.
