Abstract
A hand-held dispenser for icing cakes, consisting of a cylindrical body to contain cake icing, possibly in a liner, a piston on a piston rod to eject a stream of icing from the cylinder and through a nozzle; and a pivotal lever arranged to drive the piston into the cylinder. The piston is located alongside the cylinder so that the dispenser can be held and operated by the same hand. The piston is driven incrementally by means of a plate which is tilted to grip and drive the piston rod, and spring-loaded outwardly to free the rod whenever the lever is released.
