Product Description

1. Component Name Analysis

Term	Meaning & Explanation
28/410	Standard Specification Code. - 28: The bottle neck finish. It fits a standard 28mm diameter bottle opening, the most common size globally. - 410: The actuator/pump type code. Classically, "410" indicates a spray head designed to produce a fine mist or atomized spray. This is its core identifier as a mist sprayer.
Plastic PP	Primary Material. - PP (Polypropylene): The most common and ideal plastic for trigger sprayers. It offers excellent chemical resistance, good durability, and is safe for packaging a wide range of products.
Double Shell	Dual-Layer Housing Structure. - This means the pump has an outer decorative/protective shell covering the inner functional pump body. Benefits include: 1. Aesthetics: The outer shell can be colored, glossy, or textured for a premium look. 2. Leak Prevention: Adds structural integrity, reducing the chance of liquid seeping from pump seams. 3. Ergonomics: Provides a fuller, more comfortable grip. 4. Branding: Space for logos and text on the shell.
Trigger Sprayer / Pump	Basic Function. - The mechanism operated by pulling a "trigger" with fingers to dispense liquid.
Foam Trigger Sprayer Pump	Key Inconsistency. - "Foam" specifically means the pump is designed to mix air with the liquid solution inside a special chamber to produce foam or lather, not a mist or stream. - A true foam pump has a distinctly different internal mechanism (typically with a foaming tube/screen) and is usually labeled with codes like Foamer, FGM, or specific foam pump part numbers (e.g., 24/410 would be a foam pump on a 24mm neck).
