Abstract
Abstract A bottom lock arrangement is provided for basket carriers having opposed end panels, opposed side walls and a floor structure. The basket carriers have a center wall disposed between and parallel the side walls to provide at least two side by side cells for the carrier. The bottom lock arrangement comprises at least one connector tab extending from the center wall, and the floor structure further comprises opposed first and second floor panels. The first panel is foldably connected to one side wall and the second panel is foldably connected to the opposite side wall. The first and second panels are sized to overlap one another and they further have aligned connector slots to receive the connector tab of the center wall. Center wall connector tab configurations and cooperating aligned connector and locking slot configurations in the first and second panels are provided to yield secure bottom locking arrangments. Methods for erecting and loading the basket carriers are further provided for the basket carrier structures having the bottom lock arrangements.
