The inventions essential is that the cut outs for pouring and venting are below the sealing surface in the closed position and are crossing the sealing surface when it is in the pouring position.
The juglid of the thermos jug is for closed position lowered. For the pouring position the juglid is rotated and higher.
When the juglid is in the pouring position the cut out for pouring is crossing the sealing surface. This way the coffee can flow out. When the juglid is in the closed/brewing position the cut out for pouring is below the sealing surface. The seal is now sealing the completely around the juglid making sure no coffee can flow out.
For good pouring behaviour the jug needs to have venting. This is done with the same principle. The cut out for venting is below the sealing surface when the juglid is in the closed position and crossing the sealing surface when it is in pouring position.
With this invention it is possible to have a perfectly closed thermos jug with limited number of parts.
In the construction the seal that is sealing between the jugshoulder and the jug is used in an effective way. It is also used to seal between the juglid and the thermos jug. The seal is sealing the venting canals and the cut out for pouring in the closed position. In the closed position the seal is completely closed.
