Cliffdiver – A Leap into a New Dimension of Drinking

Like a cliff diver plunging precisely into refreshing water, Greiner Packaging’s innovative bottle solution is making waves in the beverage market: Cliffdiver. This unique 2-in-1 longdrink bottle mixes the drink automatically upon opening – creating a perfectly blended taste experience. Whether it’s whiskey & cola, vodka & lemon, or gin & tonic – this clever packaging lets consumers enjoy freshly mixed longdrinks with maximum convenience, no extra tools needed.

Behind the revolutionary Cliffdiver bottle is German company Sauerland Liquids. Manufactured by Greiner Packaging and globally one-of-a-kind, it’s setting new standards for innovation.

Smart Technology for Responsible Enjoyment

The concept is based on a clever dual-chamber system. The bottle is made up of three components: a large outer bottle, a smaller inner bottle, and a specially developed cap. Alcohol is filled into the small inner bottle and sealed with the cap. The large bottle is then filled with the non-alcoholic liquid and also sealed with the same cap – to which the inner bottle is already attached. Only when the bottle is opened for the first time does the inner chamber release, drop into the liquid, and initiate the mixing process. This delivers a unique taste experience and makes it incredibly user-friendly for the consumer.

One of the most exciting challenges for Greiner Packaging was developing the highly precise closure mechanism. The innovative cap features both an internal and external thread that securely connects both bottles. The closure is produced using injection molding, while the bottles themselves are made using the stretch blow molding process.

“With Cliffdiver, we succeeded in developing a tailor-made product that perfectly combines functionality and user-friendliness while also meeting the customer’s sustainability goals. Special thanks go to my retired colleague Rene Meußl, who played a key role in developing and advancing the project alongside the client.”

Thanks to its reclosability, the bottle also ensures greater safety - especially when it comes to protection against knockout drops.

Sustainability as a Driving Force

In addition to its innovative technology, Sauerland Liquids is committed to sustainability. The bottles are made from 30% recycled PET (r-PET) and are already integrated into the European deposit return system. This ensures the bottles are returned into the recycling loop and reused in a resource-friendly way.

Looking Ahead: Even More Applications

The potential of this 2-in-1 bottle solution goes far beyond traditional longdrinks. Sauerland Liquids sees great potential for use in the pharmaceutical industry, in food supplements and in the sports sector. For example, the small chamber could be filled with powder that only mixes with the liquid in the larger bottle upon opening – perfect for sports drinks or post-workout supplements.

“Greiner Packaging’s innovative 2-in-1 longdrink bottle opens up entirely new market opportunities for us. We see huge potential in the supplements sector, for example. The combination of fresh taste and sustainability hits the sweet spot with today’s consumers. It’s only a matter of time before this revolutionary packaging solution appears on supermarket shelves across Europe, Nigeria and the US.”

Uwe Baumgärtner, Managing Director of Sauerland Liquids.

A Leap into the Future

This groundbreaking innovation combines convenience and sustainability – a success story just getting started. And more than that: the unique mechanism, where the inner bottle drops into the outer bottle upon opening, creates a special aha moment. This element of interactivity and entertainment makes the Cliffdiver bottle not just practical, but a real eye-catcher.
