CSI's new Sport Flip Top 38mm closure design.

The Sport Flip Top 38mm is a versatile, high-performance closure designed for PET non-returnable bottles with the 1845 finish. With its sleek, ergonomic, low-profile design, the closure delivers exceptional ease of use, safety, and satisfaction for consumers of juices, sports drinks, and functional waters.

Excellent Performance

CSI’s Sport Flip Top 38mm closure provides best-in-class performance across a wide range of applications:

• Compatible with the 38mm 1845 bottle finish with non-crystallized E-wall design.
• Suitable for hot-fill processing up to 185°F and cold-fill applications.
• Withstands up to 2 bars of nitrogen and CO₂ pressure.
• Secure, linerless sealing for both shell and flip-top.

Enhanced Consumer Satisfaction

Our flip-top closure was developed with consumers in mind, focusing on safety, comfort, and ease of use. Dual tamper-evidence provides clear visual, audible, and tactile assurance, while the integrated tab eliminates loose pieces and helps reduce plastic waste. The one-hand, ergonomic opening is well suited for active lifestyles, and the hinge design allows the cap to open fully without obstruction. Most importantly, the thirst-quenching liquid flow rate enhances the drinking experience, delivering consistency and satisfaction with every use.

Total Capping Solutions

As with all CSI closures, the Sport Flip Top 38mm is backed by a comprehensive system of closures, capping equipment, and unmatched technical service. CSI’s global engineering expertise ensures robust application performance and delivers the lowest total cost of operations for bottlers and brand owners.

“The Sport Flip Top 38mm closure represents CSI’s commitment to delivering safe, convenient, and high-performance packaging solutions that align with consumer lifestyles,” said Clint Rush, Global Director at CSI. “It provides a perfect balance of enhanced tamper evidence, ergonomic design, and operational efficiency.”

The Sport Flip Top 38mm closure is available now to support brand owners seeking innovative, consumer-preferred sports cap solutions for hot-fill and cold-fill non-carbonated beverage applications.
