The invention relates to a seal assembly comprising: a seal for a bulk material container, having a ring-shaped connecting flange with a through opening and a first moving element; and a seal member for selectively sealing or opening the through opening. A container wall of the bulk material container can be attached to the connecting flange. The seal assembly also comprises a docking device having a housing, a second moving element, and a seal actuating device. In order to increase the tightness of the seal, one of the moving elements comprises a peripheral first stripping element, by means of which impurities are stripped from a surface of the connecting flange, in a closing process for sealing the though opening of the connecting flange.
A closure arrangement, comprising a closure for a bulk material container, which comprises an annular connection flange having a through-opening and a first movable element, namely a closure member for selectively closing or opening the through-opening, wherein a container wall of the bulk material container is able to be fastened to the connection flange, wherein the closure arrangement also comprises a docking device having a housing and a second movable element, namely a closure actuating device, characterized in that one of the movable elements comprises a peripheral, first stripping element such that contaminants are able to be stripped from a surface of the connection flange during a closing operation for closing the through-opening in the connection flange.
A docking device for docking a closure of a bulk material container and for emptying bulk material from the bulk material container and filling the bulk material container with bulk material, comprising a housing, a connection part for connecting the closure, a closure actuating device for actuating the closure, wherein the closure actuating device comprises a closure actuating element and an adjusting device and the closure actuating element is movable selectively between a closed position and an open position in a direction of movement with the adjusting device, wherein the docking device comprises a seal which serves to provide sealing between the housing and the closure actuating element, characterized in that the seal is under radial compressive stress in the closed position and without a closure of a bulk material container being connected to the connection part, such that the seal is pressed against an active region of the connection part.
