Specification of 38/400 Plastic nozzle cap with Silicone Valve

What is a Plastic Nozzle Cap?

A plastic nozzle cap is a specialized dispensing closure designed to control the flow of liquids, gels, or pastes from a plastic bottle. It features a narrow nozzle fitted with a 9.8 mm cross-slit silicone valve for precise, clean dispensing, making it ideal for sauces, ketchup, honey, oils, gels, cosmetics, cleaning products, and more.

Made from food-grade PP and liquid silicone, these flip-top nozzle caps include screw-on designs, anti-leak seals, and flow-control features to ensure accurate and mess-free dispensing.

The Features of 41mm plastic nozzle cap?

1. Leak-Proof Seal

The 9.8 mm silicone diaphragm passes 7-day*24-hour inverted leak-proof testing. It opens under pressure and self-closes when released, ensuring precise dosing, drip prevention, and excellent sealing performance.

2. Materials & Safety

Ø Flip nozzle cap: Food-grade polypropylene (PP), lightweight and chemical-resistant；

Ø Silicone valve: Liquid silicone rubber (LSR) one-way check valve, durable and elastic；

Ø Compliance: FDA and LFGB certified; fully meets EU Food Contact Material standards；

3. User Experience & Ergonomics

The screw-on flip-top design allows easy one-hand opening and secure re-closure. The silicone cross valve enables precise flow control—users simply adjust squeeze pressure to vary output.

4. Flow Control & Accuracy

The silicone check valve seal ensures consistent dispensing: one squeeze, one dose. No dripping, no side leakage, no extra slits.

5. Durability & Performance

Both PP and silicone offer excellent wear resistance. The reinforced butterfly hinge withstands repeated opening and closing without breaking.

6. Hygiene & Cleanability

The one-way valve prevents air back-flow to improve product preservation. It cleanly cuts off liquid and leaves no residue on the bottle mouth. Its detachable structure also makes cleaning easy.
