An article container comprising a reusable case having a rectangular bottom wall, a pair of side panels joined respectively to opposite side edges of said bottom wall and projecting upwardly therefrom, and a pair of end panels joined respectively to opposite end edges of said bottom wall and respectively joined at their end edges to adjacent end edges of said side panels to form a rigid open top structure and a disposable cover having a rectangular top wall overlying said case and being slightly longer and wider respectively than the corresponding exterior dimensions of said open top structure, a pair of downwardly extending side walls foldably joined respectively along the entire length of said side edges of said top wall, a pair of downwardly extending end walls foldably joined respectively along the entire length of said end edges of said top wall, the end edges of each of said side and of said end walls being inwardly tapered to define walls of trapezoidal configuration, a triangular panel at each corner of said top wall having its apex in coincidence with the associated corner of said top wall and having a pair of downwardly divergent side edges one of which is foldably joined to the adjacent inwardly tapered edge of the associated end wall, and collapsible web structure at each corner of the cover and foldably joined along one edge thereof to the other of said downwardly divergent side edges of the associated triangular panel and foldably joined along another edge thereof to the adjacent inwardly tapered edge of the associated side wall, and adhesive means securing each of said collapsible web structures in collapsed condition to the inner surface of the adjacent end of each of said side walls.
A paperboard blank for a disposable cover comprising a rectangular top wall, a pair of side walls foldably joined respectively to said top wall along the entire length of the side edges thereof, a pair of end walls foldably joined respectively to said top wall along the entire length of the end edges thereof, the end edges of each of said side and of said end walls being inwardly tapered to define walls of trapezoidal configuration, a triangular panel at each corner of said top wall having its apex in coincidence with the associated corner of said top wall and having a pair of divergent side edges one of which is foldably joined to the adjacent inwardly tapered edge of the associated end wall, and collapsible web structure at each corner of the cover and foldably joined along one edge thereof to the other of said side edges of the associated triangular panel and foldably joined along another edge thereof to the adjacent inwardly tapered edge of the associated side wall.
