ABSTRACT:
A toy truck simulates the dumping of granular material within a closed container which is pivotally mounted to the truck chassis and has a transparent upward facing wall to exhibit the movement of the granular material during the simulated dumping. Pivoting the container upward from its normally horizontal position causes the material to slide from a visible dumping chamber to a concealed receiving chamber, and by further pivoting of the container the material is returned to the dumping chamber for repetition of simulated dumping. A metal foil membrane may be positioned for striking by the granules to produce a sound accompanying the simulated dumping. A self-operating valve may be used to control flow of the material.
