US Patent 9517859 Stacking clip for beverage cans

A stacking clip is provided for vertically attaching two beverage cans together. The stacking clip comprises tabs and ledges used to attach to the lip of a circular rim of a lower beverage can and clipping protrusions used to attach to an undercut region in a concavity of another upper beverage can. Wings are configured to flex inward under an influence of a digit of a user to bias the ledges outward away from the central region of the clip body, detaching the ledges from the rim of the attached beverage can.
