An icing dispenser having an expandable elastic reservoir on the handle proximal end which when loaded expands a reservoir bladder under an elastic bias that tends to return the bladder to its unexpanded condition, therein uniformly impressing constant pressure on the icing within the reservoir. A reservoir neck extends from the bladder through a handle passageway to a decorator icing tip. A butterfly valve within the reservoir neck modulates an amount of icing flowing through the tip with butterfly ends angled parallel to the passageway and urged into the pliable neck at a preferred angle, slightly deforming the neck to effect a valve seal. The handle is adapted for operation in an operator's fingers as a writing instrument with icing extrusion modulated by a lever on the handle being adjusted relative to the handle by the fingers. |
