Design icons: The Coca-Cola contour bottle

How a distinctive shape became a global icon

Few packaging designs are as instantly recognisable as the Coca-Cola contour bottle. Introduced in 1915, it demonstrates how shape, function and brand identity can combine to create a lasting design icon.

The bottle was developed by the Root Glass Company in Terre Haute, Indiana, in response to a challenge to distinguish Coca-Cola from competing drinks. At a time when rival products could look similar, the aim was to create a bottle consumers could recognise, even in the dark or by touch.

From practical problem to enduring design

Designer Earl R. Dean developed the distinctive form, drawing inspiration from the cocoa bean. Its narrow waist, rounded contours and fluted surface created a memorable silhouette, while the glass construction provided a durable, reusable container.

The design helped establish a recognisable identity beyond the label. Over time, the contour bottle became embedded in popular culture, demonstrating how packaging can become much more than a container, communicating a brand’s identity through its physical form.

Bringing the design into the classroom

For design and technology teachers, the contour bottle offers a case study in user-centred design, ergonomics, materials and product identity. Pupils can explore how shape influences recognition and handling, alongside the manufacturing processes required to produce glass packaging at scale.

The bottle also raises questions about sustainability. Glass can be reused and recycled, but its production and transportation have environmental impacts. How could a bottle remain instantly recognisable while using less material? When should environmental impact take priority over brand identity?

Teachers can extend this learning through our Inspired by Industry context, Packaging with more than its Primary Use, developed with brand agency Bulletproof. This KS3 resource explores packaging design, repurposing, manufacturing and sustainability, giving pupils opportunities to apply their learning to real-world design challenges.

Explore the Bulletproof Inspired by Industry context to help pupils move from analysing an iconic design to developing and evaluating their own packaging solutions.
