DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figure 1, apparatus 10 of the present invention is shown in a fully opened condition. The apparatus includes a lower member 12 and an upper member 14 which Are hinged together at 16 to form a boxlike enclosure that can be swung open and closed. Members 12 and 14 are preferably made of plastic, such as injection molded plastic. A
suitable enclosure is available from Bell Laboratories of Madison, Wisconsin and sold under the product name "Protects 1r. Bait Station". The enclosure is 6" x 5 '/~ " and 3" high. The enclosure has a durable hinge 16 connecting the upper member 14 and the lower member 12 and includes a screw lock to secure the enclosure in a closed condition so that children or larger animals are not able to open the enclosure and reach the contents thereof.
Lower member 12 includes sidewalk openings 28 which are visible in the side view of Figure 2 and which are arranged in an appropriate size to pezmit the entry of a rodent such as a mouse. Inside member 12 there is a provided an interior wall 18 which separates the enclosure into air entry passageway having openings 28 and an inner bait chamber in which there is provided a bait 24. Bait 24 is preferably a solid bait mounted on a steel horiaontal rod 22 which keeps the bait off any moisture on the floor of the enclosure. Interior wall 18 has an opening 20 by which a rodent may enter the inner bait chamber, The top cover member 14 is provided with three applicator mounting slots 26a, 26B and 26C. Applicators 32 each comprise a flexible web which is suspended to extend within enclosure 10. Applicator 32 shown in Figure 3 is arranged to have a fabric web 36 pass through one of slots 26 and to have horizontal support member, comprising metal rod 34, engage the top 14 of enclosure 10 so that the fabric webs 36 of NY02:269450.1 -3-JU~d 15 2000 17:15 FR BAKER ~ BETTS LLP 212 705 5020 TO 0338Bi#72557010H~ P.05 A33314-072667.0135 PATENT
applicators 32 are suspended to hang into regions A, B and C respectively of enclosure 10 when cover 14 is in the closed position. Accordingly, when a rodent enters the chamber and moves through regions A, B or C, the flexible fabric web 36 of the applicator 32 will rub across the fur or skin of the rodent and apply a small amount of the chemical thereon to the skin or fur of the rodent.
In the embodiment shown in Figures 1 and 2 the applicators are arranged in positions where a rodent is likely to pass when exploring the inside of the enclosure.
In particular, the rodent will be entering by one of openings 28 and be attracted to bait 24 in the inner bait chamber of the enclosure. In reaching the bait 24 the rodent is likely to pass through and contact with either applicator 32A or 32B in the passageway from opening 28 to opening 20 and thereafter also contact applicator 32C while passing through opening 20 and approaching bait 24.
It will be understood by those familiar with the art that different size, shape and configuration of enclosures may be use in accordance with the invention and that the particular location of applicators 32 in such enclosures may be at different locations according to the arrangement ofpassages in the enclosures.
It should be additionally recognized that it may be advantageous to provide applicators 32 in a configuration wherein they can be easily replaced with new applicators to provide a renewed supply of chemicals.
Figures 3 through 14 illustrate various embodiments for applicators and applicator mounting arrangements according to the invention. The applicators shown in Figures 3 to 7 include a flexible web which has a horizontal mounting member for engaging the enclosure and from which the flexible web is suspended within the enclosure to rub over a rodent passing through the enclosure, In particular, it is desired to have the web rub over the ear lobes and contact behind the ears of the rodent, a place where rodents cannot remove the chemical.

The applicator 32 of Figures 3 and 4 includes a fabric web 36, which may be felt, cotton, wool or similar absorbent web material. A horizontal support rod 34 passes through a loop 40 formed by web 36 at the upper end by seam or glue strip 38. A semicircular cutout 42 at the lower edge of web 36, opposite horizontal support 34 provides a passage which is lower in the height of the opening than the anticipated height of the rodent, so that the fabric of web 36 rubs across the back, head and ears of the rodent passing through.
An alternate applicator 43 shown in Figure 5 includes a web 46 of similar material having vertical slits 47 forming flexible strips which hang into a passageway through which a rodent may pass in the manner of a beaded curtain. The resulting strips of the web 46 likewise rub against the back of a passing rodent. Applicator 43 is suspended from supported 44 which is in a loop formed by seam 48.
Applicators 32 and 43 may be arranged so that their respective webs pass through slots 26 while the support rods engage the top wall 14 of the enclosure.
Another version of applicator 50 shown in Figures 6 and 7 includes both semicircular opening 52 and slits 57 in web 56. Horizontal support 54 may be a U-shaped plastic part to which the web 56 is glued and may sit in top of cover 14 or may be engaged by internal support slots 60 formed on the interior walls of enclosure 10 as shown in Figures 8 and 9, Alternatively, a horizontal support bar 62 may be provided across a passageway as shown in Figure 10, preferably having pointed holders 64 for receiving applicator 70 having web 72 and optionally U-shaped support member 74 as shown in Figure 11.
Applicator 80 shown in Figures 12 and 13 includes a plane web 82 which is formed with a perpendicular portion 84 at the top edge. An adhesive strip 86 is applied to portion 84 to enable attachment to the interior of top wall 14 of enclosure 10.
