Abstract: A sealed single-dose break-open package including a first sheet of semirigid plastic material; a second sheet of flexible plastic material superimposed on and sealed to the first sheet to define a sealed pocket containing a dose of a product; wherein the first sheet of semirigid plastic material includes at least one substantially straight first incision positioned at a first edge of the first sheet, and at least one shaped incision positioned in a central portion of the first sheet, laterally and at a distance from the straight first incision.

Abstract: A break-open single-dose sealed package and method for the production thereof; the sealed package has: a first sheet of semi-rigid plastic material; a second sheet of flexible plastic material set on top of and welded to the first sheet along an annular weld, so as to define a sealed pocket containing a dose of a product; and a pre-weakened area that develops transversely and is obtained in a central area of the first sheet; the pocket is divided into two distinct and separated chambers which are insulated from one another and each contain a corresponding component of the product; and the pocket is divided into the two chambers due to a central weld connecting the second sheet to the first sheet and is weak, so as to be broken by exerting pressure on at least one of the two chambers.

Abstract: A unit for the incision of a strip made of a plastic material to cut two distinct incisions into two opposite surfaces of the strip; the incision unit has: a conveying device, which feeds the strip along a conveying direction; two support plates, which are arranged on opposite sides of the strip, so that each support plate faces a corresponding surface of the strip; and at least two incision devices, each of which cuts an incision into a corresponding surface of the strip and has a cutting element, which is supported by a support plate, and a contrast element, which is supported by the other support plate.

Abstract: A break-open single-dose sealed package having: a first sheet of semi-rigid plastic material; a second sheet of flexible plastic material set on top of and welded to the first sheet of semi-rigid plastic material to define a sealed pocket that contains a dose of a product; and an incision made in the first sheet of semi-rigid plastic material for guiding controlled breaking of the first sheet along the incision so as to bring about formation, through the first sheet, of an opening for exit of the product; the incision has along its own length a variable depth in order to determine a progressive breaking of the first sheet along the incision.

Abstract: 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 an incision (6) formed in the first sheet (2) of semirigid plastic material to guide controlled breakage of the first sheet (2) along the incision (6) and form an outlet opening for the product (5) through the first sheet (2); the incision (6) varies in depth lengthwise to break the first sheet (2) gradually along the incision (6).
