Tamper-resistant rodent bait station

摘要

A pre-baited consumer bait station for rodents which is gnaw resistant and has other design features to make the bait station resistant to rodenticide access by children, dogs, other pets, domestic animals, and nontarget wildlife. An injection molded translucent cover is permanently locked to a base about the cover's edges and center by elastic actuated hooks which engage receptacles on the base. The cover forms a labyrinth joint with a peripheral wall of the base. Double walls on exterior portions of the peripheral wall strengthen the walls where they form part of a closely confining bait receptacle which surrounds a bait block on portions of all sides. Circuitous internal passageways limit access to the bait. An interior wall extends to support the cover center.

主权项

1. A rodent bait station comprising:
a base having a floor and an upwardly extending outer peripheral wall, defining an interior and an exterior outer peripheral wall height; a lid internally locked without provision for opening to the outer peripheral walls, and overlying the base to define a bait station interior; portions of the base outer peripheral wall defining a rodent access opening; an interior wall extending upwardly from the floor; a bait receptacle defined between the interior wall and the outer peripheral wall; at least one reinforcing wall segment interior to the bait receptacle and extending substantially parallel to the outer peripheral wall along a portion of the outer peripheral wall adjacent the bait receptacle to create a double wall, the at least one reinforcing wall segment reinforced with a plurality of webs which join the at least one reinforcing wall segment to the portion of the outer peripheral wall, the at least one reinforcing wall segment extending upwardly from the floor to substantially a same height as the interior height of the portion of the outer peripheral wall; and portions substantially centrally located on the cover which extend downwardly into locking engagement with a central protrusion extending up from the base without provision for opening.
