Zeller Plastik Mexico, in conjunction with Global Closure Systems (GCS) R & D and United Closures and Plastics (UCP) in the U.K., recently launched SportGuard, a convenient and elegant new liner-less 38mm flip-top valve dispensing closure for the re-launch of Coca-Cola's preservative free sports drink, Powerade. The three-part assembly consists of a black dispensing outer closure and a white drinking spout both manufactured in HDPE. The drinking spout houses the silicone valve sub-assembly developed and supplied by UCP, Zeller's U.K. sister company. The 38mm closure caps both the 600ml and one litre sizes in the Powerade product range. For child safety the closure design complies with the Choke Hazard criteria developed by the British Soft Drinks Association for sports drinks closures.
The SportGuard design meets the stringent demands of this hot fill product. Patented drainage channels ensure that the cooling water, which remains after hot filling, drains away cleanly. In addition, the technological achievement of a liner-less closure design obviates the need for induction seal liners and the cumbersome removal routine prior to drinking the product, making it more convenient and more cost effective. The outer closure provides double security with a tamper evident band at the base and a neat tamper evident tear strip to the flip-top for optimal product integrity. With the tear strip removed, the flip-top is easily opened via the thumb recess and held on a flexible hinge in excess of 180 degrees from the spout for ease of use by the consumer.
