A lotion pump works by creating a vacuum with a piston or diaphragm. The pump is made up of several components, including a dip tube, a piston or diaphragm, a valve, and a nozzle.
When you press the pump, the piston or diaphragm is pushed down, creating a vacuum that draws the lotion up through the dip tube. The valve then opens, allowing the lotion to flow out of the nozzle and onto the skin.
Alt i alt, the lotion pump is a simple and effective device for dispensing lotion, og det er mye brukt i kosmetikk- og personlig pleieindustrien.
