ABSTRACT:
A ram assembly is designed for evacuating "bag-in-a-box" square bulk containers of viscous materials. The ram cylinder is centered over the bulk container and mounted so as to float relative to the frame allowing accomodation of various containers. An inflatable wiper seal is used in conjunction with elastomeric corner seals to tightly seal the corners.
