What is a Flip Top Cap?

Flip top caps, also known as dispensing closures or plastic bottle lids, are specially designed lids primarily used for plastic bottles. The flip top cap with valve is mad from FDA and LFGB certified food-grade plastic and liquid silicone, this flip-top cap features a built-in silicone valve that offers exceptional sealing performance and resilience. It is designed to precisely control liquid dispensing, helping to maintain product freshness and prevent contamination during storage and use. Its leak-proof design also enhances packaging efficiency by minimizing spills during the filling and transport processes.

Key Features of Flip Top Cap with Silicone Valve

1. Leak Proof:

The silicone valve inside the plastic flip top cap has a cross slit structure designed with zero clearance, enabling it to pass a 7-day*24-hour inverted leak-proof test. This ensures outstanding sealing performance.

2. Flow Control:

The non-stick cross slit valve in the flip top bottle caps allows a 100% dispensing success rate within a ±15-degree angle. With a simple squeeze, it dispenses product precisely—once per press—without leaking or creating unwanted spills.

3. Tamper-Evident:

Available in popular sizes such as 28mm and 38mm, our beverage dispensing flip top caps come with a security ring that clearly indicates if the bottle has been opened, ensuring product safety and integrity.

4. No Waste:

The inverted flip top cap's efficient design ensures the “last drop” can be fully dispensed, minimizing product waste and enhancing the user experience.

5. Durable Butterfly Buckle:

The butterfly buckle has been rigorously tested to withstand thousands of bends without breaking, offering reliable performance and extended usability.

6. Hygienic Protection

The one-way silicone cross slit valve in the snap on flip top caps prevents outside air and contaminants from entering the bottle, maintaining the cleanliness and hygiene of the food.
