Hangzhou Lecos Packaging Co.,Ltd | Updated: Oct 26, 2017

Airless Bottle Vacuum state

  The contents of the vacuum bottle and the air can be completely isolated, to avoid the product due to contact with the air oxidation and deterioration, breeding bacteria, and its high-tech concept to enhance product files. The vacuum bottles on the market are composed of a cylindrical oval container plus a piston at the bottom of the placement. Its design principle is to use the spring of the contractile force, and not let the air into the bottle, causing a vacuum state, and the use of atmospheric pressure to promote the bottom of the piston forward. But because the spring force and atmospheric pressure can not give enough strength, so the piston can not fit too tight with the bottle wall, otherwise the piston will be too large to rise and can not rise; the other hand, to make the piston easy to advance and prone to leakage material situation, So the vacuum bottle on the manufacturer's professional requirements are very high.
