Sealed Break-Open Package and Corresponding Method for the Production Thereof

A sealed break-open package (1);

• the sealed package (1) comprises:
• a wrapping sheet (2), which is folded and welded onto itself so as to define, alone, a closed containing chamber, which is designed to contain a fluid product and has a dispensing through opening (3), through which the fluid product can flow out of the containing chamber;
• and
• a closing system (4), which engages the dispensing opening (3) in a sealing manner, so as to close the dispensing opening (3);
• wherein the closing system (4) comprises a semi-rigid plastic material sheet (5), which overlaps the wrapping sheet (2) in the area of the dispensing opening (3), is firmly and permanently connected to the wrapping sheet (2), and has a pre-weakened region (6);
• and
• wherein the pre-weakened region (6) overlaps the dispensing opening (3) and guides, following a folding of the semi-rigid plastic material sheet (5), a controlled breaking of the semi-rigid plastic material sheet (5) in the area of the pre-weakened region (6), so as to determine the formation, through the semi-rigid plastic material sheet (5), of a product outlet opening.
