How to work bottle pump at liquid soap or hand body lotion

How to work bottle pump at liquid soap or hand body lotion?
A pump dispenser is used on containers of liquids to help to dispense. They might be used on bottles, jars, or tubes. Often the contents are viscous liquids such as creams and lotions. Some are metered to provide uniform usage. Some mix contents from two or more sources prior to dispensing
the principle working The soap dispensing pump relies on both the components of the bottle and air suction to draw the fluid upwards and fight against the law of gravity. Each time you push down on, or prime, the actuator, the piston puts pressure on the spring and moves the ball upward, taking some soap product with it.
