  • Patent number: 3940142
    Abstract: A die for use in a liquid filled die agitator is formed from a foldable, initially flat sheet having a plurality of discreet sections respectively adapted to define facets of the die. The sheet sections are integrally formed with one another and each is joined to at least one adjacent section by an integral foldable joint, with the sections being arrayed in a predetermined pattern so that upon folding about their associated joints, the sections will form the facets of the die. Cooperating recesses and mating posts on at least some of the sheet sections secure the sections together in the folded configuration to complete the die, while guide pins on at least some of these sections guide the sections into mating relation with one another during the folding operation.
