On the market of vacuum flask is made up of a cylinder into spheroid container plus a placed at the bottom of the piston.
Its design principle is to use metal spring force of contraction, and do not let air into the bottle, create a vacuum, and the use of atmospheric pressure to push the bottom of the piston to move forward.
But because of the spring force and the atmospheric pressure can't give enough power, so the piston can't and bottle wall joint is too tight, otherwise the piston will be caused by the rise of resistance to progress;
On the other hand, if you want to get piston is easy going and easy leakage material, so the vacuum flask failure rate is very high.
And vacuum flask piston system design space is too little, is not conducive to brand by the shape and decoration to create their own unique image.
Moreover, the structure of the vacuum flask vacuum pump head system is too complex, materials for recycling, has a high cost.
Vacuum flask of latest development trend, although complied with skin care products can effectively protect the fresh quality products.
But due to the vacuum flask structure is relatively complex, high cost, to the use of vacuum bottle packaging only a few categories of products, cannot be carried out in the market, to meet the needs of different class cosmetics packaging.
