How to use a Cream Pump Dispenser
1. Hold the nozzle part of the bottle with your hand, and rotate the upper part of the pump head counterclockwise (viewed from top to bottom).
2. Under normal circumstances, when you hear a "bang", you will see the bottle pop up. And the mouth of the bottle can be squeezed down, can be squeezed out, then the opening is successful, and the body lotion can be used.
3. If it is found to be getting tighter and tighter during the rotation, it means that the liquid storage bottle is designed with a reverse rotation switch. That is to say, it needs to be turned clockwise to open. When you hear a "bang" and see the mouth of the bottle pop out, you can press the top normally to squeeze out.
The principle of the pump head
The pump head adopts the principle of pressure suction, which uses the movement of the piston to discharge the air in the liquid storage cylinder to generate internal and external air pressure so that the liquid rises under the action of the air pressure and is discharged from the liquid outlet pipe to the outside of the pipe.
Some shampoo or shower gel pump heads will have an initial plastic buckle between the liquid outlet and the lower round cover for fixing, preventing the pump head from rotating during transportation and causing liquid leakage. . At this time, the pump head can only be turned after the plastic buckle is removed. When the opened shampoo needs to be transported or moved, you can take the pump head out of the shampoo bottle, then press the pump head to the bottom, rotate the pump head in the opposite direction marked on the bottle cap, and then tighten the pump head back to the cap, but this process It takes a certain amount of work. Finally, reinstall the pump head back into the bottle.
