Keeps liquid nice and hot. No spills
Love this thermoflask. Liquid still hot after 8 hours, and doesnt spill on side of my backpack. Collection at a busy Sainsbury's took a bit of waiting (sign for Argos collection point says go to Sainsburys customer service kiosk, which of course had a queue) so will collect at an Argos next time

Hello KB.
Thermos Stainless Steel 470ml King Flask - Gunmetal:
The flask keeps drinks hot for up to 18 hours according to the manufacturer.
They do not state how long the contents stay above 70 °C, but in practical use, water typically remains ≥70 °C for around 6–12 hours, depending on conditions.
Pre‑heating the flask can noticeably extend this time. To pre‑heat, fill the flask with boiling water, close the lid, and leave it for 5–10 minutes before emptying and refilling with your hot drink. This warms the stainless‑steel interior and reduces early heat loss, helping the flask stay above 70 °C for longer
Thank you for using Q & A.
Hi there,
After checking with our supplier, they have advised for the Thermos Stainless Steel 470ml King Flask: The Stainless king Cup has a double wall construction to prevent it getting hot. So long as the customers product still has a black plastic inner, and stainless steel outer it shouldn’t be getting too hot to hot.
Hope this helps.
Thank you for using Q & A
