Wholesale 15mm 18mm 20mm Screwed Aluminum Perfume Sprayer with Precision Pump Mechanism

It is a precision pump mechanism where the outer housing (the screw-on collar and often the actuator button) is made of aluminum, typically finished with plating (e.g., gold, silver, chrome, rose gold) or anodizing for a luxurious look and feel. The "screwed" part refers to its method of attachment: it screws directly onto the glass or plastic bottle's neck via a continuous thread.

Key Components and Features:

1. Aluminum Collar (Ferrule): The metal ring that you see on the neck of the bottle. It is screwed on during assembly, creating a secure and tamper-evident seal.

2. Aluminum Actuator: The button you press with your finger. It's often weighted and finely textured, providing a premium tactile experience.

3. Pump Mechanism (Internal): Inside the metal housing is a complex assembly of a piston, spring, chamber, and glass or stainless steel ball to ensure chemical compatibility with the alcohol-based perfume.

4. Gasket: A crucial seal, usually made of EPDM rubber, that sits between the collar and the bottle neck to prevent evaporation and leakage.

5. Dip Tube: A thin tube, often made of PE or PP, that draws the perfume from the bottom of the bottle. Its length is customized for each bottle.
