Airless pump bottle design

Airless bottle can separate the products from the air, that is a good way to depollute effectly,And it is a good packaging to sub package hign end essential oil, serum and more. Pls pay attention: It have to fill full before press it.  Let me share something with everybody about the airless structure 1, Why is there no dip tube inside the bottle, surely it do not need the tube, if it has dip tube inside, it is lotion bottle for shampoo bottle, shower gel bottle. 2, The theory of airless bottle: ALl the airless bottle is cylinder or ellipsoid container with a piston at the bottom. Its design theory by using the metal spring contraction force, and prohibit the air come in, make it to be an airless environment. 3, Airless bottle can be recycle, when pump out all the products, the piston base will up accordingly till the products finish. After finish, you can use a chopstick to press the piston part to the bottom, so that you can refill again. By using such kind of airless bottle, your productsion wont be oxy-genated any more. Besides, If you want to clean the airless bottles, pls use the cool water instead of hot water. By Canvard Packaging International Co.,Ltd http://www.cosmetic-bottles.com
