24mm 28mm Plastic Lotion Pump with Double Shell for Cosmetic Bottles

Key Components & How It Works

1. Foam Pump Mechanism (The Base):

   • Operation: When pressed down, the pump draws liquid from the bottle through a diptube. It then mixes the liquid with air inside a special chamber.

   • The Result: This aerates the liquid, pushing it through a fine mesh screen to create a thick, luxurious foam instead of a liquid stream.

   • Standard Size: The 42mm refers to the diameter of the bottle's neck finish that this pump is designed to fit. This is a common, standardized size.

2. Silicone Brush Applicator (The Head):

   • Material: Made of soft, flexible silicone.

   • Function: The foam is dispensed directly through the base of the brush. The silicone bristles are then used to gently massage and apply the foam onto the skin or other surfaces.
