Unbreakable Flask

Postby cycle cat » 2 Feb 2015, 8:26pm

I'd like an unbreakable stainless steel flask that will keep my tea hot.
My current one means the tea ends up lukewarm on day rides.
I do prime it by filling it with boiling water and shaking it.
What can people recommend?
It can go in a bag. I'm not bothered about putting it in a bottle cage.
Thank goodness for soup.

Putting a stainless flask in a neoprene bottle bag - Blacks and Cotswold sell them - does prolong warmth for a while longer than if it's naked.

I use a standard aluminium bottle from the £1 shop and an insulated sleeve like this with the addition of a foam ring on top - sorry its not quite in focus.

All my work flasks are Stanley. I swear my them. One of my newer 750ml (or is it 1l I forget) is very light. Stanley have modernised and their flasks are about a third lighter. Expensive, but I get hot beverages all day...hv

My tea was still scorching hot after 5 hour rides during Oct - Nov last year although I've yet to test it under the current freezing temps.

Thermos Ultimate. Lightweight and will keep drinks hot for over 12 hours. I have drunk coffee after 18 hours in one. There are two sizes:

I did a lot of research and tried several brands to come up with a stainless steel flask that would keep medications cool between B&B's while touring. Different models by Thermos invariably showed the least change in temperature on an all-day ride. As is so often the case, it seems that you get what you pay for.

25 years ago I got a stainless flask, made tea one morning. Put it in a pannier, wrapped in clothing.

Forgot about it that evening, and the next morning, carried on riding around Dartmoor.

That evening I poured out a tea which I had to let cool....

Basically - I second the thoughts around extra layers ;)

Had a relevant conversation with a work colleague just the other day... he reminded me that the original Thermos flask used a one piece double-walled glass liner, with a vacuum in the gap - a really effective barrier to heat-loss, but fragile... metal flasks, on the other hand, won't keep the vacuum and transfer heat like Billy-Oh. So there you have it. Hot contents or Durability - your choice!!

The originals also used a foil liner to keep the heat in. If anyone broke one, they would see not only the glass shards infecting their brew, but the shiny foil too. I had one. In the dark ages.
Switched to a stainless one because my dad, who leaves his home at 3am Sunday and doesn't get back till after 3pm the following Saturday after thousands of miles stuck in a HGV all week swears by stainless. Which I and many others also do.
I'd say your colleague, much like the Thermos flask, is also full of hot air.

The one my son got from Tesco's is not very good, his drinks cool very quickly compared to mine. Also would you buy a Tesco bike at £99?

Also why would anyone buy a flask knowing they will need to wrap it in further insulation? Surely a good flask should have it's own sufficient insulation.
