Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
190 words
An apparatus for capturing boll weevils comprising in combination: a. a base comprising an open bottom, cylindrical vertical sides, and a horizontal circular top affixed at its edge to the tip edge of the cylindrical vertical sides thus substantially forming an inverted cylinder with an open bottom allowing for movement of boll weevils up the sides due to, b. a grandlure attractant and c. a plurality of openings spaced around the top edge of said inverted cylinder to allow boll weevil entry into d. an inverted funnel attached to the top of the cylindrical base so that the edge of the inverted funnel overlaps the outer edge of the cylindrical base, said funnel affixed to the top edge of said cylindrical base, thus substantially forming a guide for the boll weevils up and through the funnel throat, said funnel throat end inserted into a e. clear capture chamber which is affixed to overlap the funnel throat end said clear capture chamber affixed and sealed to overlap the funnel throat end so that when the boll weevils enter the capture chamber they cannot return due to their nature to crawl upward.
Claim 2
Independent Claim
