Among plastic lotion pumps, a lotion pump is the most popular method of dispensing viscous liquid products in the personal care and beauty industry, and it has various shapes and sizes. When used as designed, the pump dispenses the correct amount of product again and again. But, have you ever wondered what functions in a lotion pump make it work? Although there are hundreds of different designs on the market today, the basic principles are the same. "Packaging Crash Course" breaks down one of the lotion pumps Open to give an overview of these components and how they contribute to the overall function of the pump. Product from bottle to hand. The actuator or pump head is a tool that the consumer presses to draw the product out of the container.

The actuator is usually made of PP plastic, can have many different designs, and usually has a lock or lock function to prevent accidental output. This is a component design that can separate one pump from another in terms of appearance design. This is also the part where ergonomics plays a role in improving consumer satisfaction. This assembly tightens the entire assembly onto the bottle at the end of the neck. It is a common destination for neck polishing, for example, it is usually made of PP plastic, and is usually designed to have ribbed sides or smooth sides. In some cases, a shiny metal casing can be installed to give the lotion pump a high-end, elegant appearance.

The gasket is usually friction fit to the inside of the closure, and it acts as a gasket barrier on the bottle groove area to prevent product leakage. This outer gasket can be made of many materials according to the manufacturer's design: rubber and LDPE are just two of the many possible options. Sometimes referred to as the pump assembly housing, this assembly fixes all pump assemblies in place and serves as a transfer chamber that sends the product from the dip tube to the actuator, and finally to the user's hand. This part is usually made of PP plastic. Depending on the output and design of the lotion pump, the size of the housing may vary greatly.

Please note that if the pump is paired with a glass bottle, because the side wall of the glass bottle is thick, the width of the bottle mouth may not be enough to accommodate the shell-please be sure to check its installation and function first. The parts may vary depending on 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 the metal spring from the product channel. These pumps are often referred to as having a "metal-free channel" function in which the product will not be included. Will come into contact with the metal spring-eliminates the potential compatibility problems of the metal slender plastic tube made of PP plastic, which extends the range of action of the lotion pump to the bottom of the bottle. Depending on the bottle paired with the pump, the length of the dip tube will vary. You can learn about a three-step dip tube measurement method here. A correctly cut dip tube will maximize product use and prevent clogging.
