ZJ Pack 24/400 PP Lotion Pump, 0.48cc Dosage, Twist Lock

What this packaging is

An external metal spring that never touches the formula — that's the standout engineering behind this 24/400 PP Lotion Pump with 0.48cc dosage and twist lock. Built for 24mm 400-finish necks, it fits a wide range of containers used for face cleansers, hair treatments, and hand creams. The flat-top actuator and glossy collar give it a clean, retail-ready look, while the twist lock keeps things secure during transit and retail display. Manufactured in China, it supports decoration via electroplating, spray coating, and water transfer printing — giving brand teams real flexibility to customize without switching components.

Why brands choose this

• External spring stays out of the formula: The spring mechanism sits outside the pump body entirely, eliminating metal-to-liquid contact. This makes it a cleaner fit for water-based cleansers and treatment formulas where metal exposure could affect stability or consumer perception.
• Twist lock cuts transit and retail risk: The built-in twist lock prevents accidental actuation during shipping and on-shelf display — a practical detail that reduces leakage complaints and waste, especially for higher-viscosity products like hand creams and conditioning treatments.
• Decoration-ready for brand differentiation: Compatible with electroplating, spray coating, and water transfer printing, this pump gives product developers multiple customization paths on a single component — useful for seasonal launches, limited editions, or aligning pump aesthetics to primary bottle finishes without retooling.
