I have always had issues with my lid leaking, I've had it just over 12mths and it leaks every time I wash it, last night it leaked soup all down the back and down the front (as usual) it seems to leak out of where the lid clicks into lock (on both sides, the liquid will pool and then run down the TMX) I have had the seal replaced with the new kind but it still does it. Can anyone make any suggestions?
