Abstract
A roller hockey puck having an outer shell of annular configuration, a central core positioned centrally interiorly of the outer shell, and a transition section extending from the central core to the outer shell. The transition section has a plurality of elliptical holes formed therein. The transition section has a top surface formed inwardly of a top planar surface of the outer shell. The transition section has a bottom surface formed inwardly of the bottom planar surface of the outer shell. The plurality of elliptical holes are uniformly spaced around the central core. The central core has a truncated spherical configuration with central axis aligned with a central axis of the outer shell. A plurality of runners are respectively received by a plurality of through bores formed in the outer shell. Each of the plurality of runners has a top surface extending outwardly of the outer shell. The outer shell, the central core and the transition section are integrally formed together of high density polyethylene material adapted to maintain a constant durometer between 30 degrees and 150 degrees Fahrenheit.
