ABSTRACT:
A sealing arrangement for a container in which an auger having vanes is disposed in the chamber thereof for moving particulate material stored therein. A threaded sealing member is adapted to engage the auger vanes so as to be driven along the container on rotation of the auger. The sealing member is mounted slidingly within the container but is restrained from rotating about the auger. On rotating the auger, in one direction, the sealing member moves along the auger to a storage position located beyond the auger vanes.
