Decorative icing dispenser

A hand-held icing dispenser for use by an operator in decorating a cake with icing dispensed through an icing tip, comprising,

• a reservoir with an exhaust port, adapted to receive icing and to exert positive pressure on the icing urging the icing to flow from the reservoir out the exhaust port without pressure added to the reservoir by the operator,
• an exhaust valve functionally connected to the reservoir exhaust port modulating flow of icing from the reservoir,
• a handle to which the reservoir exhaust port is connected,
• a decorator tip removably connected to the handle in fluid communication with the exhaust valve,
• a fill mechanism adapted to load icing into the reservoir,
• wherein the reservoir further comprises an expandable bladder elastic and compliant and adapted to receive icing, expanding with increased icing content loaded under external pressure, the bladder when expanded being under elastic bias to return to an unexpanded state exerting a constant pressure on icing within.
