ZJ Pack 24-400 PP Slim Self-Sealing No Drip Oil Pump, 0.48cc Dosage with Lock-Down, External Spring & Octagonal Overcap

What this packaging is

Precision-dosed at 0.48cc per stroke, this slim PP oil pump solves the number-one frustration in oil-based personal care: dripping. The 24-400 PP Slim Self-Sealing No Drip Oil Pump features a patented self-sealing head cap that auto-closes after every dispense, plus an external spring that stays completely outside the liquid path — keeping formulations uncontaminated. A lock-down mechanism and octagonal overcap add travel and retail protection. Finished with a glossy collar and slim actuator, it's a natural fit for body oil, hair oil, and treatment serums that need clean, controlled delivery. Decoration options including electroplating and spray coating make this pump easy to brand.

Why brands choose this

• External spring never contacts your formula: Most pumps run a metal or plastic spring through the liquid chamber — this one doesn't. The external spring design keeps the internal pathway clean, which matters especially for sensitive hair oils and body oil formulations where contamination or oxidation is a real concern.
• Precision 0.48cc dose with lock-down for retail and travel confidence: Controlled dosing reduces over-dispensing — a known consumer pain point with oils — while the lock-down mechanism prevents accidental actuation in bags or on shelf. As travel-sized and on-the-go formats grow across hair and body care, this combination of dose control and lockout directly supports consumer adoption.
• Patented auto-sealing head cap turns no-drip into a brand story: The self-sealing cap closes automatically post-use, eliminating the residue and mess that erode trust in oil products. In a category where consumers often reach for droppers or flip-tops out of habit, a visible drip-free pump mechanism is a genuine shelf differentiator — and a feature worth calling out in product copy.
