The Usage of Dropper

The Usage of Dropper

With the popularity of cosmetics, people's requirements for cosmetics have become higher and higher, and products that try to avoid adding preservatives have become an important factor for many consumers to choose products, so the "dropper" packaging design came into being. Face cream products contain a lot of oil and it is difficult for bacteria to survive. But the essence is mostly water-like essence, and it is rich in nutrients, which is very suitable for bacterial reproduction. Avoiding direct contact with the essence by foreign objects is an important way to reduce contamination of products. The dropper can effectively solve this problem. The use of the dropper can completely avoid the contact between the liquid inside the bottle and the hand. It needs to be in contact with the outside world. People only need to use the upper end of the dropper that is not in contact with the liquid to absorb the essence in the container, and then discharge the essence to the skin or other parts that need to be used by means of backlog. More precise and controllable, effectively avoiding waste. The design principle of the small dropper is to use a pressure pump to extract the essence in the bottle. It is very simple to use half of the bottle to find that the essence cannot be sucked up. The air in the dropper is firstly expelled by pressing. For the dropper, squeeze the dropper firmly and put it back into the bottle, do not let go to tighten the bottle mouth; if it is a push dropper, press the dropper fully when putting it back into the bottle to ensure that the air is completely squeezed out . This way, the next time you use it, you only need to gently unscrew the cap, and the liquid in the dropper will be enough for one dose.
