Sidel has collaborated in the new “spiral” PET bottle project from The Coca-Cola Company (TCCC), with the company’s 40-year expertise in PET packaging instrumental in the successful rejuvenation of the Fanta brand and the challenges involved in getting it right.
Coca-Cola started to design and develop a new proprietary Fanta packaging shape, applicable to both PET and glass bottles, in order to provide a protectable new global standard for the brand. Sidel has played a key role in the packaging project development, namely qualifying the new Fanta bottle for industrial production.
The new creative and differentiating bottle in PET designed by Drink Works represents a “rule-breaker” in terms of bottle design for CSD (carbonated soft drinks). It features a spiral, inspired by the twisting of an orange to release its juice. It is based on a series of ribs decorated with small bubbles, including a torsion in the bottom half. This spiral gives the Fanta bottle an unusual, asymmetric structure which presented a real challenge in terms of developing a container able to withstand deformation and stability issues.
The Spiral bottle required full design testing and refinement, achieved through more than 60 technical drawing iterations and FEAs (Finite Element Analysis) to test performance using computing analysis. Moreover, it involved the production of 15 pilot moulds and feasibility tests successfully managed with Sidel to achieve validation of the final bottle design.
A similar bottle shape has been deployed for the whole Fanta bottle family and it is now available for 500 ml, 1L, 1.5L and 2L formats. When it comes to the 1.5L and 2L bottles, the Spiral design offers easier gripping and an improved pouring experience for the consumer. Leveraging the successful cooperation with Sidel, an alternate 500ml Spiral bottle has been developed to ensure stability specifically for gravity-fed inclined shelves.
