The pump head design of airless pump bottles is one of the keys to the successful application of this packaging technology in the cosmetics industry. The design of the pump head not only directly affects the user experience, but also determines the output effect and sealing performance of the product.
The structural design of the pump head is one of the most important components of the airless pump bottle. Usually, the pump head mainly includes key components such as casing, pump core, nozzle and spring. The outer shell plays the role of protecting the internal structure and fixing the position of the pump head, while the pump core is the core part that generates negative pressure. The nozzle is responsible for outputting the product, and the spring is used to provide the rebound force of the pump head, so that the pump head can rebound quickly after the user presses it.
Pump head material selection is critical to the performance of your airless pump bottle. Due to direct contact with cosmetics, the material of the pump head needs to have good chemical stability to prevent chemical reactions from affecting the product. Common pump head materials include polypropylene, polyethylene, stainless steel, etc. These materials usually have properties such as corrosion resistance, oxidation resistance, and high temperature resistance, ensuring that the product is not contaminated during the output of the pump head.
In the design of the pump head, the shape and structure of the nozzle directly affect the output method of the product. Airless pump bottles usually come in a spray or dropper style design. The spray pump head sprays liquid cosmetics into mist through a special nozzle hole and atomization structure. It is suitable for liquid products, such as spray perfume or lotion. The dropper-type pump head can drip out a precise dose through special valve and pipeline designs, and is suitable for products with thicker liquids, such as essences or lotions.
In terms of user experience, the design of the pressing force and frequency of the pump head needs to comply with ergonomic principles to ensure that users can easily and accurately control the output of the product. The sensitivity of the pump head needs to be properly balanced, not only to ensure that sufficient force can be generated when pressing, but also to prevent excessive injection of product due to excessive force. Such a design can make users feel comfortable and convenient when using the product, and ensure the economical use of the product.
