The cover mechanism made the first use a rather uncertain impression, but even that has disproved the practical experience. The cover consists of a metal part (cover and pin) and a plastic part, which is inserted into the carafe opening. Several rubber lips prevent leakage of the bottle and ensure that the lid does not drop from the carafe. When pouring the metal cover is always lifted from Plastikausguss by the weight of the pin that is created between the two a Ausgussspalt down. This is an ingenious system that (unlike many an other system of higher priced manufacturers) also works very well.
To clean the carafe can be the pin, unscrew the lid, which can be separated and the two remaining parts of the lid. This is easily achieved all gaps and can after cleaning reassemble the cover.
The only real drawback to the carafe: it is very full, the lid will not open far enough and the pouring does not work without spilling. The problem can be solved by filling the carafe only up to the level of the peg, however.
All in all, the carafe at the price of their money fully value and I would not hesitate to recommend.
