Abstract: An improved weighted base for a trophy, includes a cup-shaped shell having a platform for supporting portions of the trophy above the base. A cover having a surface for resting on a table, shelf and the like is connected to the shell to define a hollow interior cavity. A fill hole in the cover provides access to the cavity and a funnel extends from the fill hole to provide a flow path into the cavity. A cross section of the flow path in the funnel is larger proximate the funnel outlet end than proximate the fill hole. Hardened filler in the base, which filler was introduced to the cavity in fluid form via the fill hole and funnel, increases the weight of the base. A vent opening connects the cavity with the external environment during filling of the base. Narrowing the funnel near the fill hole reduces loss of filler should the filler fracture in the base.
