Plastic lotion pumps are one of the popular dispensing methods for viscous (thick liquid) products in the personal care and beauty industry, and come in a variety of shapes and sizes. Many of these parts are plastic injection molded! When used as designed, the pump will dispense the correct amount of product again and again. But have you ever wondered what structural components are in a lotion pump to make it work? Although there are hundreds of different designs on the market today, the basic structure is the same. Learn an overview of these components and how they can help pull the product out of the bottle into your overall functionality.
Generally, a lotion pump consists of the following components
1. Actuator: An actuator or pump head is a tool that a consumer presses to pull a product out of a container. This actuator is usually made of polypropylene plastic and can have many different designs-and often has a locking or locking function to prevent accidental output. This is one of the component designs that can separate one pump from another in design, and it is also the part where ergonomics plays a role in improving consumer satisfaction.
2. Cap: the assembly that screwes the entire assembly to the neck of the bottle. It is identified by common neck dressing destinations, such as 28-410, 33-400. Usually made of polypropylene plastic, usually designed as ribbed or smooth sides. In some cases, a glossy metal case can be installed to give the lotion pump a high-end, elegant look.
3. External gasket: The gasket is usually fixed to the inside of the bottle cap by a friction fit and acts as a barrier for the gasket on the joint area of the bottle to prevent product leakage. According to the manufacturer’s design, this outer gasket can be made from a variety of materials: rubber, low density polyethylene are just two of the many possible options.
4. Housing: Sometimes called the housing of the pump assembly, this component holds all the pump components in place and serves as a delivery cavity that sends the product from the dip tube to the actuator and ultimately to the user’s hand. The part is usually made of polypropylene plastic. Depending on the output and design of the lotion pump, the size of the housing may vary significantly.
5. Stem / Piston / Spring / Ball (internal parts inside the housing): These are parts that change according to the design of the lotion pump. Some may even have additional components to assist product flow, and some designs may even have additional housing components that isolate metal springs from the product channel. These pumps are often referred to as having "metal-free channel" functionality, in which case The product will not be in contact with the metal spring-eliminating potential compatibility issues with metal springs.
6. Immersion tube: a long plastic tube made of polypropylene plastic, extending the range of the emulsion pump to the bottom of the bottle. The length of the dip tube will vary depending on the bottle that is paired with the pump. A properly cut dip tube will maximize product use and prevent clogging.
