Nowadays, the outstanding cosmetics is the outer packaging. The high-end and atmospheric outer packaging is the competitive advantage of many cosmetics, which is different from the inside to the outside. At present, many cosmetic bottles choose the nozzle design. Let's look at the daily use of cosmetics nozzles.
1. Clean up in time
Cosmetic nozzles should be cleaned up after a period of use. Cosmetics must be used every day. The frequency of use is very high. In order to ensure the quality of cosmetics and not adulterate any pollutants, the nozzles should be overflowed after a period of use. The cosmetics are cleaned up to ensure it is clean.
2. Cover the outer cover
After the cosmetic nozzle is designed, there will be an outer cover on it, which is mainly to ensure that the cosmetics are separated from the outside air. Therefore, the outer cover is usually closed immediately after spraying, which improves the shelf life of the cosmetics, cuts off the contact with the outside air, and improves the cosmetics performance.
To ensure the quality of the product itself during the use of cosmetics, the bottle caps should be tightened in time. For cosmetics designed with cosmetic nozzles, the outer packaging and bottle caps should also be checked for daily carrying.
Trigger sprayers are generally made from polypropylene (PP) plastic and can be used for general use (water, cleaning solutions) or chemicals. Trigger sprayers are available in a variety of colors, which can be used to identify different products in the bottles. The nozzle can be adjusted to create a fine spray or jet stream for dispensing liquids.
How does a trigger sprayer work?
1.The trigger lever, once pulled using a few fingers activates a small pump. This pump is attached to a plastic tube that draws cleaning fluid from the bottom of the reservoir inside the bottle. The pump forces this liquid down a narrow barrel and out a small hole at the spray valve.
