Delayed release bait canister and method

摘要

This invention relates to delayed release bait canisters in which a closure member covers an opening in a body member against a bias spring and is released by a corrodible link that, when intact, secures the closure in place over the opening. In one example the canister (10, FIG. 1A) has a tubular plastic body (12) fitted with cylindrical plastic end-caps (14) and having a semi-cylindrical plastic closure (16) that fits around it to cover an opening (18) formed therein. A knob (20) is formed at the center of body (12) and a similar knob 22 is formed in the center of the closure (16) near one edge thereof. The closure (16) is biased to the open position by a loop of elastic cord (24), the ends of which are secured in the end caps (14). A corrodible link (28) with end rings (30) that fit over knobs (20) and (22) is used to hold closure (16) in its closed position over opening (18), the periphery of the closure being pulled into close contact with body (12) by the tension in cord (24).
