Small, strong and award-winning

The inspiration for my colleagues’ project came from Indonesia: it is here, in particular, and in other Asian countries as well that the small water beakers made from PET are widely used. Sealed with a removable film/foil, they supply the on-the-go market for a quick thirst-quencher betweentimes. Airlines, too, like using these non-returnable beakers for their passengers – quite a few of you will have already been served with them. Then you will also be familiar with the disadvantage: once it’s been opened, the beaker has to be drunk in its entirety – otherwise you’ll be getting an involuntary shower the next time the plane encounters some turbulence. But this is only part of the improvement potential that Stephanie Wunderlich and Antje Plath have tackled: in their team, they have developed a practical, attractive alternative to the small water beakers: a flexible, reclosable small lightweight bottle.

The droplet-shaped PET bottle holds 200 millilitres, and with a weight of just 4.4 grams is extremely light. What’s particularly interesting for our clients: it can be produced on a standard blow-moulding machine suitable for lightweighting formats. An option for nitrogen injection offers the additional advantage that the containers are stabilised for storage and transport. In terms of dress, too, the mini-bottle offers multifarious design options: different labelling techniques enable several disparate designs to be implemented – despite the small size, customers need not feel deprived of distinctive design and marketing potential. In fact, the lightweight mini-bottle with its striking droplet shape is a genuine eye-catcher!

In the limelight

The bottle had its first major appearance back at the drinktec – you doubtless noticed our illuminated bottle curtain comprising more than 2,000 bottles if you visited the Krones stand? It was precisely this bottle that we used.

Numerous conversations with clients at the fair evidenced the keen interest in this development project.

The concept’s visual appearance has now also been recognised with the A Design Award. “We put ourselves forward for this prize, which is awarded every year for showcasing particularly exciting design projects. We, of course, who are responsible at Krones for container development, are very happy about this accolade!” relates Stephanie Wunderlich.

Looking into the future

When developing the lightweight bottle, Stephanie could, for example, draw upon eleven years of experience in container design at Krones – during this time, she acquired an in-depth comprehension of our clients’ wishes and needs. Meanwhile she’s working in container development as part of the Packaging Development and Consulting Team. Together with her colleagues, she is continuing to progress development of the mini-bottle: “We are toying with the idea, for example, of transferring the concept to other container sizes – perhaps that will be one of the future development thrusts.”

Even though development of the concept study is still continuing: clients could now already begin to produce the lightweight mini-bottle. “This has to be checked in each individual case, of course, but for clients buying a new line, in particular, the concept is already viable today,” emphasises Stephanie.

Here, in conclusion, are the hard facts on the bottle; I’ll be pleased to answer any questions you may have in the comments at any time.
