Company Entering Design - Moldmaker: F&S Tool, Inc Product Description: The permeation of oxygen into beverage containers or carbon dioxide out of carbonated products has a negative impact on product quality and shelf life. There has been considerable emphasis and development on beverage containers to reduce permeation. Very little development has been done to prevent permeation through the cap, other than liners added by a secondary process. This cap has a barrier co-injected during production. This barrier has 30 times more resistance to permeation than a monolayer polypropylene cap. This approach produces a single piece cap well suited for products like carbonated beverages, juices, water and tea that need oxygen or CO2 barrier protection. The cap also has a patent pending tamper evident band compatible with current market bottle finishes. This tamper evident band features a continuous conical locking band with ribs to position the locking band on the bottle finish.
Why is the product innovative? The elimination of secondary operations to insert or mold a liner results in a simpler, cost effective, robust cap design. The precise operation and control of the hot runner system produces a cap with the barrier only where it is needed. Tight integration of valve gate function, manifold heating and both injection units creates unprecedented precision and control of the barrier. Finally, to ensure that 100% of the caps have barrier all across the bottom an innovative barrier verification system is integrated into the parts handling system. This coordinated design approach allows the closure systems to be optimized for lighter weight, fast cycles, excellent quality and higher function. The combination of using the barrier technology with the efficient cooling technology makes it possible to have a greener production line, using less plastic and water.
