It is estimated a pressure of 1.5kg necessary to open the Portitionierer. When the bottle is full capacity from above the weight of a full bottle (content + glass) as a back-pressure which relieves the plastic receptacles. Is the bottle nearly empty but you just have to logically still with the same force push. The strain on the plastic intake but immensely since the plastic intake upwards only appreciated about is 6mm thick. Everyone who often works with for Plastics feel the point where you think, "Whoa, Whoa .... equal machts knack ...". The feeling I have every time a nearly empty bottle in it have the top and press the glass underneath.
In the catering industry or in a discotheque that thing would probably broken, after 1 hour. Because sometimes just as fast as a cocktail glass "kloppen topsy" does not work here. This Bar Butler must be operated gently and with feeling.
