Cosmetics packaging vacuum bottle manufacturing process

Cosmetics packaging vacuum flask is composed of outer cover, pump set, bottle, bottle inside the piston and collet combination of high-grade packaging. The launch of the vacuum flask conform to the latest development trend of cosmetics, can effectively protect the quality of the content. But due to the vacuum flask structure is complicated, the production cost is high, the use of vacuum flask is limited to individual high product variety and high requirements, more difficult to carried out in the market, to meet the needs of different grade of cosmetics packaging.

1, vacuum flask, design principle, design principle of the vacuum flask, based on the atmospheric pressure, at the same time very dependent on pump power of the pumps, pump group requires excellent one-way seal performance, cut off air circumfluence inside the bottle, bottle in low pressure state. When the low pressure area in the bottle and the atmospheric pressure difference is greater than the piston and the inner wall of the bottle of friction, the atmospheric pressure will drive a large piston moving within the bottle. So big piston and the inner wall of the bottle not fit too tight, otherwise the large piston will due to the friction force is too large to progress; On the other hand, if the piston and the joint is too loose and prone to leakage in the inner wall of bottles, so vacuum bottle to the professionalism of the production process requirement is very high.

2, vacuum flask, product features: the dosage of the vacuum flask at the same time also provide accurate control, when the diameter of the pump group, after stroke, elastic set, regardless of form a complete set of buttons modelling is why, every time consumption is precise and quantitative. And can be adjusted by changing the pumps parts and the excretion of press, precision to 0. 05 milliliter, depending on the product requirements.

once vacuum bottle filling is completed, from the production factory to in the process of consumer's hands after use, almost negligible air and moisture into the container, effectively prevent the pollution content, use process could effectively prolong product. Combined with the current environmental trends, to avoid to add preservatives and anti bacteria agent called on opposition, vacuum packaging to extend the shelf life of products, the protection of rights and interests of news is more important.
