Patent number: 6789349Abstract: A fishing lure has an attachment for a fishing line to pull the lure through a body of water to attract and catch fish. One or more hooks are attached to the body of the lure. A refillable chamber enclosed within the lure body is arranged to hold a liquid fish attractant.

One end of the wick extends from the chamber through a passage in the body of the lure to be in communication with the body of water. The liquid attractant is thereby eluted from the end of the wick in very small amounts as the lure is pulled through the water to attract fish to the lure.Type: GrantFiled: June 10, 2003Date of Patent: September 14, 2004Inventor: Charles Stone
