GERMANY - U-Boot Getränke is banking on a worldwide first in the spirits sector, with an innovative packaging concept from Greiner Packaging that offers consumers greater convenience in purchasing special mixed cocktails.
The German spirits company 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 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
This 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 (plastic bottles and containers).
“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.”
Both the PET 30ml inner bottle and 140ml outer bottle are manufactured by injection stretch blow molding, while the HDPE seal for is injected. The outer bottle is screen-printed with UV drying colours, while the seal is printed with pad printing.
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.
