A spill-proof smart closure system for non-carbonated soft drinks has been released globally.
German-based Actega DS and SmartSeal SA from Norway have devised the solution for the 'on-the-go generation' using the Flex28 closure.
Designed by SmartSeal SA, it is an automatically activated valve design that gives users hands-free spill control on top of the traditional sports closure features.
The technology resembles that of valves used for scuba diving, with the valve triggered by under-pressure in the mouth while the user is drinking. When suction is applied to the closure, the valve releases and expels water, and when suction is removed the valve closes again, preventing any liquids from spilling. Another attribute is the 180-degree hinged lid that stays out of the way when drinking.
The closure system was made possible with the use of a sealant compound provided by Actega DS. The company has experience handling thermoplastic elastomers, and it collaborated with SmartSeal to produce the final product: the Polyliner 677 PFT. This was commercialised with the SmartSeal Flex closures for non-carbonated soft drinks. The compound is a PVC-free granulate conforming with FDA and EU regulations.
PFT is a treatment to ensure the compound has sensory properties which ascertain no off-taste of the filled goods, and the compound is designed for sports drink applications.
SmartSeal SA's Paal Steensland said SmartSeal closures were steadily gaining popularity worldwide.
“Developed to prevent children from spilling drinks in the back of the car, the closure is not only perfect for small children but provides the consumer with a different experience. It is practical for sports drinks, suitable for the on-the-go consumption or daily hydration, and useful to people who have an active lifestyle and want to bring a bottle with them in their bag or when exercising.”
“The closure system could is also a selling point for beverage brands looking for new ways to differentiate themselves and stand out in a crowded market.”
The Smart Seal Flex28 comes in both long (1810) and short (1881) versions. A 38mm version, also suitable for hotfill, is being developed and should be ready by Autumn 2016.
