The invention claimed is: 1. A sealed package for pourable food products, made from sheet packaging material in combination with an opening device, the combination comprising a package having a top wall and a plurality of side walls and a bottom wall; the side walls and top and bottom walls being arranged to provide a sealed package; at least one transverse sealing band extending across the top wall and forming a flat projecting tab folded coplanar with and onto the top wall of the package, the top wall having a bend line in the packaging material; and an opening device mounted on a portion of said top wall bounded on one side by said sealing band and on an opposite side by an intersection of the top wall and one of the side walls; wherein said tab comprises a flat striplike auxiliary portion interposed between said sealing band and said bend line, so that the area of the portion of said top wall available for said opening device is increased by the width of the auxiliary portion; and wherein said opening device is superimposed on said top wall and on said auxiliary portion of said tab. 2. A package as claimed in claim 1, wherein said sealing band divides said top wall into a first portion and a second portion, the first portion defining the portion for receiving said opening device, and the second portion being smaller in area than the first portion. 3. A package as claimed in claim 2, wherein said tab and said sealing band extend beyond said top wall at opposite lateral walls of the package, and define, with said top wall and said lateral walls, respective flat, substantially triangular lateral portions of packaging material folded coplanar with and onto respective lateral walls as of said top wall; said bend line being formed at the base of said tab, and comprising a main portion formed along said top wall on the side of said second portion, and opposite end portions formed on both sides of respective said lateral portions. 4. A package as claimed in claim 1, being generally parallelepiped-shaped. 5. A package as claimed in claim 1, wherein said top wall comprises a convex C-shaped front edge projecting outwards and defining, on the opposite side to said sealing band, the portion of the top wall available for receiving said opening device. 6. A package as claimed in claim 5, wherein said front edge comprises a straight intermediate portion parallel to said sealing band; and two oblique end portions diverging towards the sealing band and connecting said intermediate portion to respective lateral edges of said top wall. 7. A package as claimed in claim 5, wherein said first portion of said top wall is, at least at the portion, for receiving said opening device, oblique with respect to the horizontal and slopes downwards towards said front edge; and wherein said second portion of said top wall comprises at least one additional bend line to tilt the second portion in the same direction as said first portion. 8. A package as claimed in claim 1, comprising a flat rectangular bottom wall; and a front wall, a rear wall and lateral walls connected to one another by beveled intermediate portions. 9. A package as claimed in claim 8, wherein said beveled intermediate portions taper towards said top and bottom walls and converge at respective vertices of the top and bottom walls.
