Abstract

An interlocking clip, a container incorporating the interlocking clip, and methods of fabricating of the interlocking clip and container are provided. The interlocking clip is formed integral with first and second container sections for fastening the container sections together, and includes a tab-receiving aperture and a locking tab. The tab-receiving aperture is formed through a container wall of the first container section, and the locking tab is formed from, and integral with, a container wall of the second container section. The locking tab is bendable to interlock with the tab-receiving aperture, and includes bendable extensions on opposite sides of the locking tab. The bendable extensions include wall-receiving grooves to receive the container wall on opposite sides of the tab-receiving aperture in the first container section. In operation, the locking tab inserts into the tab-receiving aperture to interlock the first and second container sections together.
