Dust cap dust cap: The dust cap is usually made of PP plastic, often made in a transparent form, used as a dust cap and safety cover, which can protect the actuator from collecting dust and prevent accidental startup. To help the package stand out on the shelf, the dust cover can be produced in stock or custom colors.

Actuator Actuator: usually made of PP plastic, this is the component that consumers press to spray the product out of the bottle. Unlike the actuator on the lotion pump, the actuator of the fine mist sprayer has internal components that include inserts to create a specific atomization pattern of the product to be sprayed. Some fine mist sprayers have a locking function to prevent accidental dispensing.

Actuator plug-in insert: This tiny component consists of channels through which liquid flows, forming a mist-like pattern. In many cases, this insert can be installed on the outside of the actuator and is the part where the product leaves the sprayer.

Closing the cap: the assembly that fixes the entire assembly to the bottle. It is usually made of PP plastic and can come with many surface treatments or designs-including ribbed, smooth, matt or shiny treatments. In some cases, metal shells can also be used to further increase the shelf appeal of the packaging. This component should have industry standard neckwear, such as 18-410, 20-410, 24-415, etc.

Gasket: The outer gasket is used as a compressible seal to seal the seal on the bottle's land to prevent leakage. Depending on the product/chemical composition, different gasket materials need to be used, and the gasket is a key component that must be tested to ensure compatibility. It can be customized using BUNA, neoprene, plastic rubber, LDPE and other different materials.

Mechanism: It usually consists of many components, such as piston, housing cover, valve stem, spring, seal and the entire housing. This is the part that transfers the product from the inside of the bottle to the actuator. Generally speaking, when the actuator is pressed down, the spring will compress, thereby pulling the product through the dip tube to the inside of the housing. The subsequent drive pumps the liquid upwards through the piston towards the actuator and is discharged from the pump through the actuator insert. The components that make up the mechanism vary by design, but the sprayer shown here includes a piston, a valve stem, a spring, a seal installed in the housing, and a housing cover. Then install the mechanism to the cover and snap it together with the actuator to fix it in place.

Dip tube dip tube: a long and thin plastic tube that extends the scope of the sprayer to the bottom of the bottle. Unlike the dip tube of a lotion pump (usually thicker), the dip tube of a fine mist sprayer is usually slightly bent to reach the bottom of the bottle's push-up area and cut into a "V" shape or angle to avoid clogging.
