Engineered for personal care brands that ship to retail and e-commerce. A leak-proof locking mechanism, 5 neck size options, and premium closure finishes — all from a single ISO-certified platform.

One Pump. Zero Leaks. Every Time.
The most common return reason for lotion and soap products is simple: the pump leaked during shipping. Labels get ruined. Cartons get greasy. Customers demand refunds. The K201-4 screw-down lock eliminates this entirely.
Twist the head clockwise — the internal gasket compresses into a positive seal that survives drops, vibrations, and pressure changes during air freight. Twist counterclockwise — the pump rises and dispenses a calibrated 1.80-2.00ml dose with consistent rebound every single time.
No clips. No caps to lose. No customer frustration. Just a pump that works exactly the way your brand needs it to.
Where Other Pumps Fail
Problem 1Pumps unlock in transit. Product leaks onto labels, into packaging, and onto other items. Returns spike 3-5%.
SolutionScrew-down lock with internal gasket compression. Leak rate under 0.2% in real-world e-commerce shipping.
Problem 2Inconsistent dosage — some pumps spit, others barely output. Customers question product quality.
SolutionCalibrated 1.80-2.00ml/stroke with ±5% tolerance. Flow-tested during production. Same feel every pump.
Problem 3Plastic spring pumps lose tension after months. Customers must manually pull the head back up.
Solution304SS or 316SS metal spring. 100,000+ cycle endurance. No plastic fatigue. No manual resetting.
Problem 4Cheap plastic closures undermine premium branding. The pump looks like a commodity on the shelf.
SolutionAluminum shell, UV coat, bamboo-look, and water transfer closures. Premium finish without changing your bottle.
Closure Finishes
Match your brand positioning with five closure options:
- Aluminum Shell — Silver, gold, rose gold, or matte black. Weight and cold-touch feel signals luxury to the consumer at first contact.
- UV High-Gloss — Scratch-resistant protective coating. Any Pantone color. The most popular choice for vibrant brand palettes.
- Bamboo-Look — Wood-grain transfer texture. Pairs beautifully with amber glass or frosted PET bottles for natural-positioned brands.
- Water Transfer — Marble, carbon fiber, or custom patterns. Stand out in categories where every brand looks the same.
- Standard Ribbed — Classic gripping texture in any color. Cost-effective for high-volume value lines.
