Abstract: The disclosed partitioned wastebasket has component pieces including an outer receptacle, one or more partition inserts, and a cover, operatively interfitted relative to one another. The outer receptacle has a bottom wall and a side wall upstanding therefrom to an open upper top, and opposing handles are formed adjacent the open upper top. Each partition insert is sized to fit closely adjacent the outer receptacle walls, and has front and rear hooks that thereupon become operatively interfixed to the outer receptacle to hold each partition insert within the outer receptacle and to hold the outer receptacle side wall against outward flexture. Hinge structure between the cover and each partition insert movably supports the cover for opening and closing the outer receptacle.
