GERMANY – riha WeserGold Getränke GmbH & Co KG has opted to use an innovative new carton bottle packaging for its not-from-concentrate juices of its well-established ‘Naturella’ brand.
Developed by SIG Combibloc, the carton bottle – branded ‘combidome’ - is manufactured entirely from a cardboard composite and is topped with the single-action domeTwist screw cap. Inside the combidome filling machine, which produces 12,000 packages per hour, the two Components are assembled into the finished carton pack, aseptically filled and securely sealed.
Christoph Kenn, System Project Manager for combidome at SIG Combibloc, explained, “At 28 mm, the internal diameter of the closure is very large – as it’s positioned in the centre of the carton top, this makes for extremely smooth pouring action, and enables users to drink conveniently straight from the carton pack”.
The large-sized closure is integrated into the carton using a new sealing process. While normally the base is sealed and the carton is then filled and sealed across the top inside the SIG Combibloc filling machines, and the closure is affixed afterwards using an applicator, the process with combidome is different.
First, the closure is moulded onto the ‘neck’ of the package – the ‘dome’ that gives combidome its name. The carton is then moved upside down into the filling zone, where it is sterilised and filled. At the end of the process, the base is sealed.
Thomas Mertens, Managing Director Materials Management at riha WeserGold Getränke, believes the company has made the right choice with combidome: “combidome is an eye-catching package, and it’s the perfect vehicle for placing a really great product centre stage.
“It looks like a bottle and is just as easy to use, but combidome also offers all the advantages of a carton pack, because the entire package is manufactured from an eco-friendly cardboard composite.
“Packaged in this composite material, our juices are perfectly protected. And economically, too, beverage cartons are a great choice,” he added.
