ABSTRACT:
The device fills a hole in an ice rink surface and has a chamber to receive a slush mixture. An access allows the slush mixture to be deposited into the chamber. The chamber has a lower end and a valve is located at the lower end for dispensing the slush mixture from the chamber. The valve includes a housing with an aperture and a valve member is dimensioned to fit within the aperture and is movable from a closed position to an open position. A trigger opens the valve to dispense the slush mixture. The valve can then be used to press the slush mixture into the hole, thereby to restore the ice rink surface.
