Abstract: A system for dispensing controlled amounts of flowable materials having a wide range of viscosities, such as food condiments, caulking or adhesives, from a flexible-walled container or bag includes a housing for holding the flexible-walled container and a piston positioned within the housing to apply pressure to a wall of the flexible-walled container. An enfitment, which has a piercing member and sealing mechanism, is positioned adjacent an opposite wall of the flexible-walled container. By rotating the enfitment about a rotational axis generally normal to the wall of the first container, the enfitment forms an opening in the flexible-walled container and a seal with the container. The flowable material can then be forced through a hollow tube of the enfitment and an exit nozzle coupled to the enfitment.
