Abstract
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.
Claims18
A single-use rodent bait station comprising:
- a base comprising a floor, a first retaining receptacle, and an outer peripheral wall extending from the floor, the outer peripheral wall defining an upper peripheral edge and at least one rodent access opening;
- a lid, the lid and the base defining a bait station interior, the lid comprising a first prong that protrudes from the lid into the bait station interior;
- an interior wall extending from the floor toward the lid, the interior wall having a first end spaced apart from the outer peripheral wall;
- and
- a bait receptacle defined between the interior wall and the outer peripheral wall, wherein a portion of the interior wall defines a side of the bait receptacle,
- wherein the first retaining receptacle extends from the interior wall, and the lid is internally locked without provision for opening to the outer peripheral wall by the first prong that engages the first retaining receptacle, wherein such engagement eliminates access to the bait receptacle through a perimeter defined by the upper peripheral edge;
- wherein the perimeter defined by the upper peripheral edge is unbroken, wherein the upper peripheral edge of the base and an outer peripheral edge of the lid meet along a labyrinth joint;
- and wherein the labyrinth joint extends around an entirety of the perimeter.
A single-use rodent bait station comprising:
- a base comprising a floor, an interior wall, a first retaining receptacle, and an outer peripheral wall extending from the floor, wherein the first retaining receptacle is spaced apart from the outer peripheral wall and the outer peripheral wall defines an upper peripheral edge and at least one rodent access opening;
- a lid, the lid and the base defining a bait station interior, the lid comprising a first prong that protrudes from the lid into the bait station interior;
- and
- a bait receptacle defined in the bait station interior, wherein a portion of the interior wall defines a side of the bait receptacle, wherein the bait receptacle is accessible only using a bait access path defined between the at least one rodent access opening and the bait receptacle;
- wherein the interior wall extends from the floor toward the lid;
- and
- wherein the first retaining receptacle extends from the floor and from the interior wall, and the lid is internally locked without provision for opening to the outer peripheral wall by the first prong that engages the first retaining receptacle, wherein such engagement eliminates access to the bait receptacle through a perimeter defined by the upper peripheral edge;
- wherein the perimeter defined by the upper peripheral edge is unbroken, wherein the upper peripheral edge of the base and an outer peripheral edge of the lid meet along a labyrinth joint, and wherein the labyrinth joint extends around an entirety of the perimeter.
