"vacuum" flasks

I don't suppose any of you guys could recommend a decent brand of "vacuum" flask?

My 5 month old "Aztec" 1 litre stainless steel flask is now no longer keeping things hot - when I
pour in a hot drink, the outside wall of the flask gets hot a half hour later :-(

Doesn't seem right to me... I did get a replacement stopper free of charge from the manufacturer as
the rubber o-ring had perished, but even with the new stopper the outer wall is still getting hot.

It is broken. Take it back to the shop and get your money back. Graham

I might get in touch with the makers of the flask, and see if they will exchange for a new one,
after all it's supposed to have a 10 year warranty. (They did replace the stopper free of charge, so
hopefully they should replace the flask as it's faulty)

I remain to be convinced that stainless steel flasks keep their contents hot as well as old
fashioned "Thermos" flasks. Tried it, but back to the old fashioned method for me. (Yes - I know all
about priming, insulating etc etc etc). Another triumph of gadgetry over function.

I rather like tea without glass shards in it. The stainless steel unbreakable flasks might not be as
efficient as the silvered glass ones but they don't break if you or your sac take a tumble. Now
leaving a thermos in the car to drink after a walk is a mighty good idea, especially if you are
parked miles from anywhere.

One of the mags did a review of a whole bunch of stainless flasks and at least one
traditional glass.

IIRC the best stainless were as good as the glass. The worst stainless were very poor.

Gadgetry? Making a flask out of something that doesn't break if you drop it? Hardly. Metal flasks
keep the liquid hot all day - what more do you want?

I am convinced they are very poor compared with one I must have had for over 20 years! I just looked
and it is a genuine Thermos - made in England.

The SS one was a present from my daughter a few years ago, hasn't been used much, barely keeps
it warm for a day's walk, and even with the stopper screwed hard in if I shake the flask it
leaks, probably via the patent pourer, which enables you to pour with the stopper unscrewed part
way. Useless!

Any chance of laocting the article? Very interested to see what was as good as glass.

Not being in the habit if falling over (touch wood), I've never actually broken a glass flask. I'd
imagine one would have to be particularly unlucky to fall in just such a manner as to produce such a
shock (and I'd be more worried about my camera). But I could be convinced if I could find a
stainless one which worked.

Well - I'd like a flask that actually DID keep the liquid hot all day. No matter whose SS flask
I've compared against, and whatever preparatory methods are used, my drinks are always hotter.
Admittedly this is more of an issue in the depths of winter, but then I never have a hot drink in
summer anyway.

and how many times have you dropped a flask?

I broke one in 30 years walking. On a cobbled slippery path my legs shot from under me and I sat
down painfully. The flask was at the bottom of the sack and took the same blow.

Since then I have always had some kind of padding under the flask, when I carry one.

Quite. I've never had any problems with mine. I've got two stainless steel flasks, and they're both
brilliant. Much better than the lottery with the glass getting in the water.

Stainless flasks came first by the way. Then some bright spark in Scotland called Dewar invented a
glass strong enough to hold a vacuum without shattering....

79.84% of all statistics are made up on the spot. The other 42% are made up later on. In Warwick -
looking at flat fields and that includes the castle.

Aladdin do some of the best stainless flasks. My 1 litre one is outperformed by a 1 litre Thermos by
about 2C in the first four hours which isn't that bad.

My smaller noname stainless 0.5 litre fares worse although that's probably due to it being smaller -
6C in four hours (below the Thermos)

I once took the inner of a three litre Thermos and stuck a base plate and the innards of a
Mullard 360 tetrode inside - took my father ages to realise that it wasn't actually some form of
exotic RF tube!

Better still is a stove and kettle and tea and coffee and... various other goodies waiting for
you when you get back. Takes 5 mins to brew up, and it's much nicer than tea that's been in a
flask all day.

I have broken a flask (the same one) twice and in neither case was it as the result of falling or
dropping. The first time was on a Scottish summit one Easter back in the 70s when I put my rucksack
down on what I thought was soft snow. Since then I haven't carried a Thermos on the hill. The second
only a winter or 2 ago when one of the several bags I was carrying gave the stone jamb of the garage
doorway a glancing blow. This time the flask went straight into the bin. Sheer carelessness in both
cases but in neither was much force required, just an unfortunate proximity between a slow moving
flask and hard stone.

Mine's an Aladdin Atlas and I'd recommend it to anyone.

Not sure, but judging by the number of dents, quite a few!
 
Interested in this thread. I have a SS flask but it leaks. It is one of those ones where you press
in a button then pour. Useless. Can anyone suggest a 0.75 litre SS flask which does not leak,
preferably one with no fancy press button/pour type thingies. I do not use a thermos, because I have
broken a couple, mind you that was in my mountaineering rather than walking days.
