A revolution for a classic: The first U-boat from a bottle

The German company U-BOOT GETRÄNKE is banking on a worldwide first in the spirits sector, with an innovative packaging concept from Greiner Packaging.

Kremsmünster, April 2015. Fans of mixed drinks now have every reason to celebrate. The German company U-BOOT GETRÄNKE is introducing a classic on to the market - one that was available for decades only in selected restaurants and pubs. This first of its kind product launch was made possible, thanks to Greiner Packaging's system solution skills, using an innovative “bottle-in-the-bottle” concept. 

The classic “U-boat” is a schnapps glass filled with high-proof spirits that is dropped into a glass with soda.  It had previously been impossible to order a U-boat in clubs, bars, or the like where drinks were dispensed only in bottles.  Together with Greiner Packaging, U-BOOT GETRÄNKE accepted this challenge and has developed new packaging that pays tribute to the “mixed drink” concept.

Innovative total solution
A packaging solution that is part soda and part alcohol has been on the market since December 2014, providing the classic U-boat experience even without the benefit of glasses.  “We developed a bottle-in-the-bottle concept and mastered the challenge of functionality and product safety.  Both bottles are sealed with the same cap which, when unscrewed, detaches the smaller inner bottle  ̶  the “U-boat”  ̶  from the seal; the U-boat then sinks in the bigger outer bottle,” explains Günter Ausserwöger, Head of Division Kavo. “We are proud of this packaging solution since it clearly underscores the Greiner Packaging's strengths in innovation.  The new type of packaging now provides U-boat drinks for the first time as filled, finished products.” Greiner Packaging has once again provided its customer with a state-of-the-art total solution, consisting of a bottle, seal, and decoration.

U-boat drinks are available in four flavors (“Blue”: glacier water liqueur with lemon soda, “Green”:  Herb liqueur with energy drink, “Yellow": Vodka with orange soda, “Orange”: Vodka with energy drink).  This innovative system solution is perfectly suited for skiing areas, as well as clubs and discos.
