lotion pump bottles

Refers to a vacuum bottle with the outside air temperature to make the container or isolated bacteria isolated from the external container.cosmetic jar‍ Prevailing on the market is composed of a cylindrical vacuum bottle into an oval container placed at the bottom of the piston plus a composition. Its design principle is the contraction of the metal spring, and does not allow air into the lotion pump bottles , creating a vacuum state, and the use of atmospheric pressure to push the bottom of the piston forward. However, due to the spring force and atmospheric pressure can not give enough power, so the piston does not fit with the sides of the bottle tightly, otherwise the piston will not be too large because of cosmetic tubes‍ the resistance rises ahead; conversely, to allow the piston forward and easily prone to leakage of material circumstances, Therefore, the failure rate is very high vacuum bottle. And too little vacuum bottle piston system to design the space left is not conducive to shape their own unique brand image by shape and decoration. Furthermore, the structure of the vacuum bottle pump head system is too complicated, is not conducive to recycling of materials, the cost is relatively high. 

Although the introduction of the vacuum bottle of skin care products conform to the latest trends, can effectively protect the quality of the product fresh. However, due to the vacuum bottle more complex structure, high cost is high, the use of vacuum bottles confined to a limited lip balm case‍ number of categories of products, not in full swing in the market, to meet the different grades skincare packaging needs.
