vacuum flask壓泵無吸管，使內料與空氣可以完全隔絕，避免產品因接觸空氣而氧化變質、滋生細菌，并以它的高科技概念提升產品檔次。市場上通行的真空瓶是由一個圓柱體成橢圓體容器加一個安置底部的活塞組成。

Its design principle is to use the contraction force of the spring, and do not let the air into the bottle, resulting in a vacuum state, and the use of atmospheric pressure to push the bottom of the bottle piston forward.

Vacuum bottles are filled by vacuum filling machines.

Vacuum filling machines are machines that fill bottles at pressures below atmospheric pressure, using continuous vacuum suction to draw the product into the container, the continuous suction being generated by a vacuum pump connected to a vacuum chamber and a special filling valve.

The process of filling cosmetics is not a vacuum environment. After the finished cosmetic product is filled into the container, the gas will be pumped out through the machine, so that bacteria will lose the hotbed of production. However, whether or not bacteria enter depends on the production process of the cosmetic product and the preservation condition at the time of use.

Vacuum filling machine is a machine for filling bottles under pressure lower than atmospheric pressure, using continuous zhi continuous vacuum suction, the product is pumped into the container, its continuous suction is generated by a vacuum pump connected to the vacuum chamber and a special filling valve. The process is generally as follows: boxes with empty bottles are stacked on pallets and sent by conveyor belt to the pallet unloading machine, where the pallets are unloaded one by one, the boxes are sent to the unloading machine along with the conveyor belt to remove the empty bottles from the boxes, and the empty boxes are sent by the conveyor belt to the box washer, where they are cleaned and then conveyed next to the cartoner in order to load bottles containing beverages into them.

Empty bottles taken out from the unloading machine are sent by another conveyor belt to the bottle washing machine for sterilization and cleaning, and then inspected by the bottle inspection machine to meet the cleanliness standard before entering the filling machine and capping machine. Drinks are loaded into bottles by the filling machine. The bottles filled with beverages are sealed by the capping machine and conveyed to the labeling machine for labeling. After labeling, the bottles are sent to the cartoner for loading into boxes and then sent to the pallet stacker for stacking on pallets for delivery to the warehouse.
