28mm Chemical Professional PP Black Full Plastic Trigger Sprayer Household Car Cleaning Bottle
Of course. Here is a detailed overview of the 28mm trigger sprayer, a common and versatile component in packaging.
What is a 28mm Trigger Sprayer?
A 28mm trigger sprayer is a dispensing closure designed to be fitted onto a compatible bottle or jar. The "28mm" refers to the diameter of the finish (the neck opening) of the container it is designed to screw onto.
It's a mechanical pump that uses a trigger lever to draw liquid from the bottle and expel it as a fine mist, stream, or foam, depending on the actuator head.
Key Components and How It Works
-
Closure/Cap: The outer shell, typically made of PP (Polypropylene) for its durability and chemical resistance. It has internal threads that screw onto the 28mm neck of the bottle.

Trigger Lever: The part the user pulls. It's the lever that actuates the pump mechanism. This is often made of a more flexible plastic like LDPE (Low-Density Polyethylene) or PP.

Piston Chamber: The core of the pump. Pulling the trigger creates a vacuum, drawing liquid up the...
-
Dip Tube: A long, thin tube that reaches to the bottom of the bottle to ensure nearly all the product can be dispensed.
-
Actuator/Nozzle: The head where the liquid is expelled. It often has a tip that can be rotated to switch between a fine mist (spray) and a solid stream (jet).
-
Gasket/Seal: A small ring (often made of LDPE or silicone) that creates a leak-proof seal between the sprayer and the bottle neck.
