Abstract: A direct-formed mouthguard is provided. The mouthguard is formed from a blank which includes an inner layer, a rigid core disposed adjacent to and coextensively with the inner layer and an outer layer disposed adjacent to and coextensively with the core. Impressions of the user's intra-oral structures are made in the inner and outer layers by heating the blank to a predetermined temperature range and subjecting the blank to bite pressure. The impressions are set and the finished mouthguard is formed by cooling the blank below the predetermined temperature range. The core is formed from a material having a softening temperature above the predetermined temperature range and therefore provides structural support for the inner and outer layers when the blank is heated to the predetermined temperature range and after the blank is cooled to form the finished mouthguard.

Abstract: A road hockey puck in the shape of a cylindrical body. The body is defined by a pair of mating cylindrical sections having inner and outer faces. Each inner face is provided with hemi-spherical cavities which extend through the outer face. A spherical ball is placed in each cavity such that when the mating sections are joined to form the cylindrical body a portion of each ball will extend beyond the outer surface of each section and thus provide a puck which can be propelled on each of its flat faces.
