Thermos flask guide
What to look for in a thermos flask
Searching for the best thermos cup or thermos flask? Thermoscup is built around three things that matter most: real double-wall vacuum insulation, a way to check the temperature without opening the lid, and a mouth wide enough to actually clean.
A flask that tells you the temperature
Most thermos cups make you guess. Thermoscup's built-in LED display reads your drink's temperature live, so you know before you pour.
Built for tea, not just coffee
A removable 304 stainless steel tea separator comes with every Thermoscup, so loose-leaf tea and infused fruit work as well as coffee or plain water.
Tap. Check. Drink.
Touch the lid and the LED display shows your drink's live temperature in °C - no guessing before you sip.

Double-wall 304 stainless steel

Vacuum insulation between two layers of stainless steel keeps your drink at temperature far longer than a single-wall bottle.

Included with every flask
Brew loose tea, not just carry it.
A removable 304 stainless steel tea separator sits inside the flask, so loose-leaf tea and infused fruit work as well as coffee.

No fuss, in or out
Wide mouth. Easy to fill, easy to clean.
A wider opening than most flasks means ice cubes go in without a fight, and a bottle brush actually reaches every part inside.

Steady wherever you put it
Won't tip over your desk.
A textured, non-slip base keeps Thermoscup steady on a car console, a desk or a train table - and every part that touches your drink is BPA-free.

Questions about Thermoscup.
What is a thermos flask?
A thermos (or vacuum flask) is a double-walled container with a vacuum gap between the walls. That vacuum barely conducts heat, so it slows down how fast a hot drink cools or a cold drink warms up - that's what keeps drinks at temperature for hours instead of minutes.
How does Thermoscup keep drinks hot or cold?
Thermoscup uses double-wall 304 stainless steel vacuum insulation, the same principle behind any quality thermos flask. It's rated to keep drinks hot for up to 12 hours and cold for up to 24 hours, so your morning coffee is still warm at lunch.
How do I clean my Thermoscup?
The wide mouth opening is designed for easy cleaning - hand wash with warm soapy water and a bottle brush, rinse thoroughly and air dry with the lid off. The tea separator lifts out to clean separately. Avoid dishwashers and abrasive cleaners, which can damage the seal and the LED display.
Is Thermoscup BPA free?
Yes. All parts that touch your drink are BPA-free, food-grade 304 stainless steel.
What is the LED display, and does it need charging?
A small digital display is built into the cap and shows your drink's live temperature in °C when you touch it - no buttons, no app, no charging cable to lose.
What's included in the box?
One Thermoscup Smart LED Flask in your chosen colour, with its removable 304 stainless steel tea separator fitted.
How is Thermoscup different from a standard insulated flask?
Most insulated flasks give you no way to check the temperature without opening the lid. Thermoscup adds a live LED display built into the cap, plus a removable stainless steel tea separator, as standard.
What is your returns policy?
30 days to return an unused Thermoscup in its original condition for a full refund. Your statutory rights are unaffected. See our Returns Policy for the full details.
Where do you deliver?
We currently deliver within the UK only. See our Shipping Policy for delivery timescales and costs.
