How long will my rCUP keep my drink warm for?

In most cases your rCUP will keep your drink warm for over 90 minutes – plenty of time, even for the most slow-sipping coffee drinker.


Push Open / Push Close

rCUP has a unique ‘push open push close’ lid.

rCUP is open when the push button is in its down position, and closed when raised. As a guide, when you can see the moulded line on the inside of the lid, the rCUP is open. You don’t have to unscrew the lid to drink from the cup. Just push.

Fill Line

To avoid spillages when you put the lid on, ask your barista not to fill above the marked fill line.

The lid won’t push down when filled with a hot drink. Why?

Hot liquid over 65°C can cause steam pressure to build-up inside a sealed cup. If the push button becomes stiff to operate due to pressure build up, loosen the lid first to relieve the pressure.

DO NOT FORCE the push button as liquid could spurt out.

Is rCUP dishwasher safe? 

Yes, the rCUP is dishwasher safe, but top shelf only.

If needed, you can pop off the push button for better cleaning access.

How often do I need to clean my rCUP?

We recommend you clean your rCUP after every use.
If you need a deeper clean you can put it in the dishwasher (top shelf).

How do I look after my rCUP so it lasts as long as possible?

rCUP is only watertight if the seals and mechanism are kept clean.
We suggest that you clean your cup after every use and we can’t be held responsible for leaks if foreign objects become trapped in the seal or mechanism.


Can I take the lid apart to clean it thoroughly?

The lid can most definitely be taken off to clean – we recommend the top shelf of the dishwasher if you have one.

To take the lid off use the end of a spoon.
It’s feels tight but it’s designed for it and will be fine.

To put the lid back on, you need to push hard. First make sure you close/shut the mechanism, then rest on a hard surface and push it back on.

How about staining?

Most plastics can stain if you put them next to oily or greasy foods in a dishwasher (spaghetti bolognese is the classic!).

If this does occur, apply a mixed teaspoon of baking soda and water, leave for 20 minutes, then rinse thoroughly.


Is rCUP BPA free?

Yes it is. Of course it is!
So our reusable cup is not only made from recycled coffee cups, the cup itself can be fully recycled. Luckily, thanks to its life span of over 10 years, this is something for the future. Tea or coffee sounds more like the question for now. Enjoy!

How much of rCUP is made from used cups?

Because it’s currently impossible (commercially) to make a recycled polymer food safe, only the outer layer of rCUP is made from used paper cups: about 40% of the cup. We are working with our recycling partners and major UK retail brands to make a food grade recycled polymer commercially viable and hope to integrate this into rCUP within 9 months. Phase 1 launch of rCUP is just the start!

rCUP is still predominately plastic, and plastic is bad for the environment isn’t it?

Thankfully, we are all very aware of the effect plastic can have on the environment when used irresponsibly. Plastic is a great material that has a pivotal role to play in today’s society. It can also be widely recycled and reused time and time again: in theory exactly like glass. The issue, and what we need to get better at, is ‘capture and reuse’ and that is what rCUP is all about. Single use plastic is wasteful and often ends up as litter. We need to switch to robust, long lasting, reusable plastic products that can be recycled time and time again.

How do I recycle my rCUP at the end of its life?

Firstly, we will do everything possible to help you extend the life of your rCUP. If the seals of your cup eventually degrade and leak, just call us and we will replace them – they are easy to switch over. If the mechanism fails, just call and we can supply you with a new lid. If your cup does eventually need recycling then you can just place it in your curbside recycling. All local recycling facilities accept and process Polypropylene which is why we’ve used it throughout rCUP. The small stainless steel spring in the mechanism will be picked up within the sortation process and recycled separately.
