Abstract
A molded plastic base has a cylindrical side wall with three rodent access openings to passageways which lead to an internal feeding chamber containing rodent bait, the passageways providing multiple rodent feeding positions at the feeding chamber. A dome-shaped lid has finger recesses permitting the lid to be gripped and rotated with respect to the base. A latch secures the lid, for release without the need for a key. Narrow flanges extend inwardly from the lid to engage beneath outwardly protruding flanges on the upper parts of the base side wall. A portion of the base side wall is resiliently deflectable inwardly such that rotation of the lid causes a cam surface tooth to be depressed by a lid flange. Once past the tooth, the resilient side wall portion returns to its original condition locking removal of the lid until the side wall portion is depressed from the outside.
