Query: explodes!

unlike the smaller version from OXO this has a major design problem. when fully sealed for travel it does not vent off enough steam to prevent the entire plastic top from popping off at the seam. = hot liquid everywhere! burning your hands, liquid in your briefcase, etc! As far as I know it is the only high capacity (24oz) thermos that you can drink from directly, so I am now at a loss to replace it, as this is ideal for me to sip as I drive to work and still have coffee for the office too. OXO fix this problem please!
