Abstract
A mixer includes a mixing container held in a machine stand, with an outlet opening in the bottom of the mixing container, and a closure cover which can be reciprocated between a closed position in which the closure cover closes the outlet opening and an opened position in which the closure cover does not close the outlet opening. The closure cover is connected to the machine stand by way of a four-bar linkage including four rotary joints, wherein a first and a second rotary joint of the four-bar linkage are arranged on the closure cover and a third and a fourth rotary joint of the four-bar linkage are arranged on the machine stand.
