Abstract: A system for dispensing a viscous comestible product. The system receives a bag containing the viscous comestible product. The bag has a bag body and a bag nozzle. The system includes a dispenser having a dispenser body defining a chamber for receiving the bag. The chamber has a surface with an opening defined therein adapted to receive the bag nozzle. A first protrusion is disposed proximate to a perimeter of the opening. The first protrusion extends from the surface generally inwardly into the chamber and is adapted to abut and flex the bag body into a configuration facilitating a flow of the viscous comestible product therefrom.
