Spill proof dishwasher safe travel mug

[hollyisalovelyname]

I sm looking for an absolutely spillproof, dishwashable mug for my cup of tea on the go.
Any suggestions please?
I have had Contigo brand. Useless- once on their side they drip and have ruined work papers on me and they cost over twenty quid!!!

Bump

DP has had a bodum one for years that is great, I think from TK Maxx originally. It is probably an old version of this-

It does seal properly and is insulated. It is has been used daily for about 5 years and is still going strong.

Many thanks.
