Abstract
A sealed package (1, 1′) for pourable food products, made from sheet packaging material and having a top wall (6) crossed by a transverse sealing band (15) forming flat projecting tab (21) folde d coplanar with and onto the top wall (6) along a bend line (22), and an opening device (8) fitted to a portion of the top wall (6) bounded on one side by the sealing band (15); the tab (21) has a flat striplike auxiliary portion (25) interposed between the sealing band (15) and the bend line (22), so that the area of the portion of the top wall (6) available for the opening device (8) is increased by the width of the auxiliary portion (25).
Claims12
1) A sealed package (1, 1′) for pourable food products, made from sheet packaging material and comprising a top wall (6) crossed by at least one transverse sealing band (15) forming a flat projecting tab (21) folded coplanar with and onto the top wall (6) along a bend line (22), and an opening device (8) fitted to a portion of said top wall (6) bounded on one side by said sealing band (15);
- characterized in that said tab (21) comprises a flat striplike auxiliary portion (25) interposed between said sealing band (15) and said bend line (22), so that the area of the portion of said top wall (6) available for said opening device (8) is increased by the width of the auxiliary portion (25).
4) A package as claimed in any one of the foregoing claims, characterized by being generally parallelepiped-shaped.
8) A package as claimed in any one of the foregoing claims, characterized by comprising a flat rectangular bottom wall (7);
- and a front wall (2), a rear wall (3) and lateral walls (4, 5) connected to one another by beveled intermediate portions (70).
10) A method of producing a sealed package (1, 1′) of a pourable food product from sheet packaging material, said method comprising the steps of:
- forming a box-shaped element (60) open at the top and filled with said food product;
- forming a top wall (6) for closing said box-shaped element (60) and crossed by at least one transverse sealing band (15) forming a flat projecting tab (21) bounding, on one side, a portion of the top wall (6) for receiving an opening device (8);
- folding said tab (21) coplanar with and onto said top wall (6) along a bend line (22) formed beforehand on said packaging material;
- characterized in that said step of forming said top wall (6) is performed by sealing the top of said box-shaped element (60) at a predetermined distance (Z) from said bend line (22) on said packaging material, so that, when folded, said tab (21) comprises, between the bend line (22) and said sealing band (15), a flat striplike auxiliary portion (25), the width of which increases the area of the portion of said top wall (6) available for receiving said opening device (8).
