A sealed single-dose break-open package (1) having: a first sheet (2) of semirigid plastic material; a second sheet (3) of flexible plastic material superimposed on and sealed to the first sheet (2) of semirigid plastic material to define a sealed pocket (4) containing a dose of a product (5); and a pre-weakened area (6), which extends transversely and is obtained in a central area of the first sheet (2), so as to guide, following a folding of the sealed package (1), a controlled breakage of the first sheet (2) in correspondence to the pre-weakened area (6); the pre-weakened area (6) has a single inner incision (7), which is oriented transversely and is obtained through an inner surface (8) of the first sheet (2), and a single outer incision (9), which is oriented transversely, is obtained through an outer surface (10) of the first sheet (2), and is transversely staggered relative to and longitudinally aligned with the inner incision (7). |
