ABSTRACT:
A flying disc water toy is described. The toy preferably is circularly disc-shaped and includes a hard body, or upper external layer of closed-cell polymer foam material and an adhered soft body, or lower external layer of open-cell polymer having relatively defined fluid carrying capacity. The upper body preferably forms a relatively thin outer shell that extends laterally, through a smooth curve defining a peripheral region and then downwardly to provide a circularly air-confrontative airfoil providing substantial lift. The lower body preferably forms a relatively thick inner liner that extends substantially coextensively with the outer shell, and terminates in a circular edge or frusto-conical shaped radiating edge that inclines downwardly and inwardly from the terminal lower edge of the outer shell. The preferably forty-five degree (45.degree.) inclined edge of the lower body cooperates with the smoothly rounded peripheral region of the upper body to produce a controlled, even dispersal in a pinwheel pattern of water absorbed and contained within the lower body during the spinning flight of the thrown flying disc water toy. In a preferred embodiment, the disc has a substantially uniform thickness over its entire extent, with the upper body itself preferably being a laminate of an outer ethylene-vinyl-acetate (EVA) foam layer and an inner cross-linked polyethylene foam layer, and with the lower body preferably being a polyurethane foam layer.
