Abstract
A follower plate device for sealing and evacuating a container that has a cylindrical inner contour and contains a particularly paste-like liquid. The device comprises a seal arranged on a periphery of the device and designed so as to be able to be inserted into the cylindrical inner contour of the container such that it seals around the periphery, and marking the boundary between an outer side of the device and an inner side of the device, and a line extending through from the inner side to the outer side of the follower plate device, arranged on the outer side for connecting to a line connection leading further to an evacuation pump. The follower plate device further comprises a replaceable open-pored porous component through which the line is guided.
