The catalyst for the business was to use magnetic technology to prevent everyday coffee spills,’ she said. Critically, we had to move away from being just a reusable cup to providing complete reusable solutions for business and customers,’ Eleanor explained.

The team is also incorporating an element of software into its offering by embedding RFID chips in the base of each cup. Reusable coffee cups normally come in a range of sizes to suit different coffee consumption habits. A lot of them hail from the US or Australia, however, so it’s common to see volumes listed in fluid ounces. A 4oz cup such as KeepCup’s XS holds 118ml of liquid – so it’s ideal for espresso or piccolo – whereas Stojo’s 16oz (454ml) Biggie cup is designed for long coffee drinks and smoothies. If you just want a regular mug-sized coffee, the 12oz (341ml) size should suit you nicely. But the changing landscape also drove changes within TOPL, with the company’s offering evolving to a more solution-based model. With the product having come a long way since its first iteration, Eleanor says that one of the keys to TOPL’s success has been listening to the market and being prepared to make changes.When our clients approached us with the brief “ to create the world’s best reusable coffee cup”, naturally we stepped up. But, thanks to the efforts of Jersey-born entrepreneur Eleanor Humphrey and her father, Stewart, such mishaps could be a thing of the past. As a design consultancy with over 20 years of experience, here again we were able to use our expertise in creating the manufacture drawings and in-tool engineering. Reusable coffee cups are typically made from recyclable plastic, glass or bamboo fibre. While plastic is lightweight and durable, it may affect the flavour of your coffee: something to consider if you’re a real aficionado. Glass is the best option for those who want to focus on flavour, and it’s really easy to clean. It’s much heavier, though, and likely to break if it slips out of your hands. Cups made from bamboo fibres are biodegradable and dishwasher safe, but you can’t pop them in the microwave if you need to reheat your brew. What size should I go for?
