Does this product exist? (Other suggestions welcome!)

[GlowFlo]

I'd like a flask type box big enough to hold a jacket potato and beans that I can prepare/cook in the morning, and it's still warm at lunchtime. Does this product exist and where can I buy it?!
(If anyone else wants to ask about whether products they need exists, feel free to ask on this thread too!)

Google food flask, lots of things like this on the market: www.amazon.co.uk/Hydro-Flask-RF12005-Insulated-BlackBerry/dp/B09BZ4J5BX/ref=asc_df_B09BZ4J5BX/?tag=googshopuk-21&linkCode=df0&hvadid=696285193871&hvpos=&hvnetw=g&hvrand=6084178121962740443&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9046080&hvtargid=pla-2281435178818&psc=1&mcid=701d37b8cb7b3ff586fb530f7d5b298b&th=1&psc=1&hvocijid=6084178121962740443-B09BZ4J5BX-&hvexpln=74&gad_source=1

Good shape & can go in microwave if necessary. Bought similar in TKMaxx.
