Abstract
A portion control dispensing apparatus for dispensing precise portions of a product in a tightly controlled manner that minimizes waste caused by residual product left undispensed in a container. The device provides a dispenser for fluid products stored in a flexible container, enabling a portion control pump combined with an extrusion apparatus to squeeze the flexible container, thus continuously directing all remaining product in the container towards the dispensing end. A portion control pump removes product from the container by peristaltic action. A preferred embodiment of the apparatus comprises a frame with an upwardly spring biased carriage configured to removably hold a flexible container that holds product to be dispensed. A pair of rollers is preferably situated at the top of the frame and is positioned such that the carriage will pull the flexible container upward between the rollers as product is dispensed from the container.
