Made of plastic material, light weight, abrasion resistance and drop resistance. Plastic gaskets are added to the jar to isolate pollution, protect the cream from pollution, and at the same time increase the tightness and prevent cream leakage. Pink + white, the color matching is simple but not simple.
The magical effect of plastic bottle dropper
Most of the caps of the essence plastic bottles are small droppers. What are the advantages and disadvantages of using a small dropper on the plastic bottle?
Essences are mostly water-like refined, rich in nutrients, which are very suitable for the reproduction of bacteria. In order to avoid direct contact with the essence of foreign objects (including hands), a small dropper is an important way to reduce product contamination. At the same time, the dosage is more accurate, effectively avoiding waste. The main function of the small dropper arranged in the bottle body is to get the correct dosage and resist pollution. However, there is also a downside, that is, there will be a little bit of the essence left after use, which is a bit wasteful. Usually the pipe head of the dropper design can not reach the bottom of the bottle, and when the product is used to the last bit, the dropper will inhale part of the air at the same time, so it cannot be used up completely, which is far more wasteful than the vacuum pump design .
The design principle of the dropper is to use a pressure pump to suck up the essence in the bottle. It is very simple to find that the essence cannot be sucked up after half of the use. Use a pressing method to drain the air inside the dropper. If it is a squeeze type For the dropper, squeeze the dropper and put it back into the bottle, do not loosen your hand to tighten the bottle mouth; if it is a push-type dropper, you need to press the dropper completely when putting it back into the bottle to ensure that the air is completely squeezed Out. Next time you use it, just unscrew the bottle gently without squeezing it. The essence is enough for one use.
The proportion of the essence used in plastic bottles is as high as 80%. The reason is that the degree of change is high. Various sizes, specifications, shapes, colors, transparent and solid colors can be done. Lightweight, easy to transport, good printability, recyclable, etc.
