ABSTRACT:
The invention relates to a refillable container that implements the first-in/first-out principle for highly viscous media, with an interior chamber delimited by a bottom and side walls and with a removal channel formed in the bottom of the container and with a follower plate placed loosely in the interior of the container, said plate sealing off the interior chamber and being sealed off from the side walls of the container, said plate further being movable upward or downward under the influence of pressure in the interior of the container, with a filling chamber for the medium being capable of being isolated from the interior chamber between the follower plate and the bottom of the container, and with a filling channel for loading the medium into the filling chamber and with a vent channel for venting the filling chamber running through the follower plate, and with the filling channel and air supply channel each being connectable with a line brought out of the container and being sealable as well.
