Title: LEAKS (pours out -not drips) even when rubber in "locked" position. Epic Design fail!!
Review: There is no way to prevent a leak unless its always in the upright position!!! for a thermos with a tight closing lid, this is the worst idea that I have seen in such an otherwise very nice product. what I am referring too is this small piece of rubber that you push one way to drink and another way to close (when not drinking) on top of the lid. However, even in the "closed" position the liquid still POURS OUT if tilted diagonally.. (that's only supposed to happen when the rubber is pushed in the "open" position.) again bad idea to whoever designed that piece at Thermos. I will try to return this for a thermos that actually becomes leak proof/spill proof when fully tightened & closed.P.S. I did order the 20 oz food thermos (same "work" line series from thermos) and the 40 oz thermos (both work line) and I am expecting that they wont have the ill-thought design that this product has.
