Plastic lotion pumps are one of the most popular dispensing methods for viscous (concentrated liquid) products in the personal care and beauty industry, with various shapes and sizes. When used according to the design, the pump will distribute the correct product quantity again and again. But have you ever thought about what can make the lotion pump work? Although there are hundreds of different designs on the market at present, the basic principle is the same. The packaging crash course takes apart one of the lotion pumps to let you understand these components and how they help to pump the product from the bottle to the hand.
Generally speaking, the lotion pump consists of the following components:
Pump Actuator Actuator: The actuator or pump head is a device that consumers press to pump the product out of the container. The actuator is usually made of PP plastic, which can have many different designs, and is usually equipped with a lock or lock function to prevent accidental output,. This is a kind of component design. When external design is involved, one pump can be separated from another, which is also the part where ergonomics plays a role in customer satisfaction.
Pump cover Cover: The part that screws the entire assembly to the neck of the bottle. It was identified as a common neck polishing destination, such as 28-410, 33-400. It is usually made of PP plastic and is usually designed with ribbed or smooth side surfaces. In some cases, a shiny metal housing can be installed to give the lotion pump a high-end and elegant appearance.
External gasket of pump gasket: the gasket is usually installed inside the closure cap by friction and acts as a gasket barrier in the cap area to prevent product leakage. According to the manufacturer’s design, this outer gasket can be made of a variety of materials: rubber and LDPE are just two of the many possible options.
Pump housing: Sometimes referred to as the pump assembly housing, this part holds all pump components in place and acts as a transfer chamber to transfer product from the dip tube to the actuator and finally to the user. This part is usually made of PP plastic. Depending on the output and design of the detergent pump, the dimensions of this housing may vary greatly. It should be noted that if you pair the pump with the glass bottle, because the side wall of the glass bottle is thick, the bottle opening may not be wide enough to install the shell – be sure to check its installation and function first.
Internal components of pump rod/piston/spring/ball (internal components inside the housing): These components can be changed according to the design of the washer pump. Some pumps may even have additional parts to assist product flow, and some designs may even have additional housing parts to isolate metal springs from the product path. These pumps are often referred to as having a “metal free path” feature, where the product does not contact the metal springs – eliminating potential compatibility problems with metal springs.
Pump dip tube: a long plastic tube made of PP plastic, which can extend the lotion pump to the bottom of the bottle. The length of the dip tube will vary depending on the bottle that the pump is paired with. Here is a three-step dip tube measurement method. A properly cut dip tube will maximize product usage and prevent clogging.
