At present, the domestic manufacturers of bottle caps are mainly three types: plastic bottle caps, wine bottle caps and pump heads. Compared to plastic bottle caps, the profits of wine bottle caps and pump heads are relatively higher.
 
    Mainly speaking about the pump head, the pump head is mainly used in cosmetic bottles or household detergent bottles. Because the pump head has higher technical requirements in production than ordinary bottle caps, the profit will be relatively higher. At present, domestic pump head manufacturers are mainly located in Yuyao, Ningbo. As a humanized and convenient design, the pump head is very popular abroad. Therefore, a large part of the pump head like Hongda Pump Industry is used to meet the needs of foreign customers.
 
    Speaking of pressure pumps and pump heads, because they are very convenient to use on liquid fluids, they have been used in many product packaging in recent years, such as detergent bottles, lotion bottles, cosmetic bottles, etc. In the past, more of these products were packed in hoses, which are easy to squeeze, but the hoses are single in shape and not suitable for large-capacity packaging, so pressure pumps and pump heads are more popular in the market.
 
    There is also a certain difference between a pressure pump and a pump head. Pressure pumps are mainly based on squeezing out liquid or foam from the pump head. They are mainly used in shampoo products and detergent bottles. The pump head mainly sprays the liquid uniformly, and requires precise dosage. It is mainly used for packaging cosmetic bottles and medicine bottles. Although pressure pumps and pump heads have undergone market applications and improvements, their quality has become more and more reliable, and they are rarely used in half and cannot be discharged. However, in use, we still find that when using the pump head and pressure pump packaging, there are many times when the liquid at the bottom of the bottle cannot be completely used. This is a place worth improving. After all, when many home consumers find that they cannot be completely used, they have to unscrew the pump head to use the pressure pump in other ways, which is a very inconvenient consumer experience.
