ABSTRACT:
A system for dispensing controlled amounts of flowable materials having a wide range of viscosities, such as food condiments, from a flexible-walled container or bag includes a second container for holding the flexible-walled container and a piston positioned within the second container 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. A desired amount of flowable material can be consistently dispensed from the flexible-walled container by controlling the displacement of the piston along a predetermined piston travel length for each dispensation of flowable material. Because the flexible-walled container can have an uneven shape, the piston displacement is determined based on, among other parameters, the number of dispensations which have already been made, the viscosity of the dispensed material and the initial quantity of material within the container.
