ZJ Pack 24-400 PP Flat Top Lotion Pump, 0.48cc Dosage with Twist Lock & External Spring

What this packaging is

An external spring design sets this pump apart — positioned completely outside the pump body, it never contacts the formula inside, making it a smart pick for sensitive actives, preservative-free formulas, or anything where metal-liquid interaction is a concern. The 24-400 PP Flat Top Lotion Pump delivers a precise 0.48cc dose per stroke with a twist-lock mechanism that prevents accidental dispensing during transit or retail display. Built from polypropylene and finished with a smooth, glossy collar, it fits cleanly into face cleansers, moisturizers, hair treatments, and hand sanitizers. Compatible with standard 24-400 neck finishes and available with electroplating, spray coating, and water transfer printing for brand-forward customization.

Why brands choose this

• Formula-safe external spring for reactive or preservative-free products: The spring sits entirely outside the pump mechanism, eliminating metal-to-formula contact — a critical advantage for brands formulating with vitamin C, acids, or clean-beauty actives where ingredient integrity is non-negotiable.
• Precise 0.48cc dosage plus twist lock for retail and travel confidence: Consistent low-dose dispensing reduces waste and gives consumers dose control, while the twist-lock prevents leaks in transit or retail environments — a combination that aligns with growing consumer demand for functional, spill-proof packaging.
• Wide decoration compatibility for brand-specific shelf presence: Electroplating, spray coating, and water transfer printing options give product developers real flexibility to align this pump with premium or trend-forward aesthetics across face, hair, and hand care ranges — without sourcing a custom component.
