Abstract
An integrally molded plastic rodenticide dispenser has a base with a floor from which exterior sidewalls extend upwardly. A lid is joined to the base by an integral hinge. The lid is pivotal about the hinge to selectively cover and uncover the base. A passageway for pests, in particular rodents such as rats, is formed within the interior volume of the covered base by two converging barriers, the ends of which are spaced from one another to define a rodent feeding trough. Each barrier is comprised of two segments: a base barrier segment which is integrally formed with the base and extends upwardly from the base floor a distance less than the height of the base sidewalls, and a lid barrier segment which is integrally formed with the lid and which protrudes from the lid. The lid barrier segment is aligned with the base barrier segment when the lid covers the base to define a barrier across a portion of the base to block the passage of pests through the barrier. Pairs of prongs extend upwardly from the base barrier segment in spaced opposed relation, such that the lid barrier segment when it covers the base is engaged between the prongs to thereby restrict displacement of the lid barrier segment. Two spaced pockets are formed within the base which have ledges which receive lid protrusions. The locks so formed are inaccessible to tamperers, yet are conveniently opened by those provided with a two-tabbed key.
