What is a 38-400 Flip Top Dispensing Cap?

A 38-400 flip top dispensing cap is a specialized bottle closure designed for squeeze dispensing applications. Unlike traditional bottle caps, this closure combines a flip lid structure with an internal silicone dispensing valve to provide controlled liquid dispensing without leakage.

The cap is compatible with bottles featuring a 38-400 neck finish and is commonly used for inverted squeeze bottles. Users can simply flip open the lid and squeeze the bottle to dispense the required amount of liquid.

Features of the 38-400 Plastic Flip Top Dispensing Caps

1. Integrated Silicone Valve for Leak Prevention

The built-in silicone valve creates a self-sealing system. When the bottle is squeezed, the valve opens smoothly to release liquid. After dispensing, the slit valve automatically closes to prevent dripping, leakage, and contamination.

2. Large Diameter Design for Better Dispensing

Compared with standard bottle caps, the 38mm opening provides higher liquid flow capacity, making it suitable for thicker liquids such as sauces, shampoos, and detergents.

3. Double Wall Structure for Upside-Down Storage

The double-wall design supports inverted bottle storage, allowing products to stay near the dispensing opening. This design improves user convenience and helps consumers use almost every drop.

4. One-Hand Operation Flip Lid

The flip top structure allows easy opening and closing with one hand, improving consumer experience and convenience during daily use.
