Abstract
Abstract A container cover for use with a multi-sided container having flaps attached to the ends of at least some of the sides thereof along a fold line so that each flap is foldable against the side to which it is attached, the cover including a multi-sided planar member having an equal number of sides as the container and an area approximately equal to the transverse cross-sectional area of the container, a first skirt member extending generally laterally away from the planar member, a second skirt member extending from the planar member in the same direction as the first skirt member and being generally parallel to and coextensive with the first skirt member and spaced inwardly therefrom a distance approximately equal to the thickness of the container side and the flap and locking tabs on one of the skirt members extending toward the other of the skirt members whereby, when the cover is telescopically applied to the container, the flaps are folded against their respective sides and snugly received between the skirt members and the ends of the flaps are engaged by the locking tabs to lock the cover in place.
