Abstract
Abstract This invention relates to vermine control devices in general, and more specifically to a low profile rodent contact poison delivery device which is intended to be placed along a runway or path normally traversed by the rodents, and which is designed in such a manner that the rodents will traverse the device, thereby picking up a contact poison on their feet, skin and fur which will cause their eventual demise.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
A contact poison delivery device for depositing a particulate poison on the feet and fur of a rodent traversing at least a portion of its length, wherein the device comprises a thin walled elongated open-ended triangular tubular member, dimensioned to form a restricted passageway for rodents entering the device, and having a vertical wall member, a horizontal wall member, and an angled wall member; wherein, the said angled wall member is provided with a centrally disposed aperture, which permits the introduction of particulate poison into the interior of the device, intermediate the ends, the said horizontal wall member is provided with poison retention means adjacent its ends, at least one of the said wall members being provided with means for inducing the frenzied activity of a rodent upon contact therewith, disposed intermediate the ends of said at least one wall member, and wherein the vertical wall member, the horizontal wall member, and the angled wall member are fabricated from a material which will create a static electric charge, by the contact of the rodents fur with the interior walls of the device, whereby there will be both, a direct static electric attraction, and a rubbing transfer, of the particulate poison onto the rodents fur.
Claim 2
Dependent Claim
204 words
A contact poison delivery device for depositing a particulate poison on the feet and fur of a rodent traversing at least a portion of its length, wherein the device comprises a thin walled elongated open-ended triangular tubular member, dimensioned to form a restricted passageway for rodents entering the device, and having a vertical wall member, a horizontal wall member, and an angled wall member; wherein, the said angled wall member is provided with a centrally disposed aperture, which permits the introduction of particulate poison into the interior of the device, intermediate the ends, the said horizontal wall member is provided with poison retention means adjacent its ends, at least one of the said wall members being provided with means for inducing the frenzied activity of a rodent upon contact therewith, disposed intermediate the ends of said at least one wall member, and wherein the vertical wall member, the horizontal wall member, and the angled wall member are fabricated from a material which will create a static electric charge, by the contact of the rodents fur with the interior walls of the device, whereby there will be both, a direct static electric attraction, and a rubbing transfer, of the particulate poison onto the rodents fur.
Claim 3
Dependent Claim
28 words
A contact poison delivery device as in claim 1; wherein, the poison retention means comprise a raised lip formed integrally with the ends of the horizontal wall member.
Claim 4
Dependent Claim
27 words
A contact poison delivery device as in claim 2; wherein, the poison retention means further comprise felt pads disposed adjacent the ends of the horizontal wall member.
Claim 5
Dependent Claim
35 words
A contact poison delivery device as in claim 1; wherein, the means for inducing frenzied activity by the rodent upon contact therewith, comprises an adhesive strip disposed intermediate the ends of the horizontal wall member.
