Abstract: A production method for producing a sealed break-open package comprising the steps of: making, through an outer surface of a sheet and by means of a first tool, an outer incision, which at least partially extends into the area of the pocket; and making, through an inner surface of the sheet opposite the outer surface and by means of a second tool, an inner incision, which is parallel to and aligned with the outer incision. The inner incision is made only after the outer incision has been completed and by making the second tool perform a working stroke, which brings a tip of the second tool inside the outer incision.

Abstract: A break-open sealed package is disclosed; the sealed package includes: a first sheet of semi-rigid plastic material; a sealed pocket, which contains a dose of a product and is delimited on one side by the first sheet; and a pre-weakened area, which guides, following a folding of the first sheet, a controlled break of the first sheet in the pre-weakened area to form an outlet opening for the product through the first sheet. The pre-weakened area is arranged at one end of the first sheet and extends from a first outer edge of the first sheet to a second outer edge of the first sheet to divide the first sheet into a holding portion and into a folding portion that is smaller than the holding portion.

Abstract: A sealed break-open package having: a wrapping sheet, 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, through which the fluid product can flow out of the containing chamber; and a closing system, which engages the dispensing opening in a sealing manner, so as to close the dispensing opening. The closing system having a semi-rigid plastic material sheet, which overlaps the wrapping sheet in the area of the dispensing opening, is firmly and permanently connected to the wrapping sheet, and has a pre-weakened region, which overlaps the dispensing opening and guides, following a folding of the semi-rigid plastic material sheet, a controlled breaking of the semi-rigid plastic material sheet in the area of the pre-weakened region, so as to determine the formation, through the semi-rigid plastic material sheet, of a product outlet opening.

Abstract: A sealed break-open package; the sealed package has: a first sheet of semi-rigid plastic material; a second sheet of flexible plastic material superimposed on and sealed to the first sheet to define a sealed pocket that contains a dose of a product; and a pre-weakened area that is created in a central area of the first sheet for guiding, following bending of the sealed package, controlled breakage of the first sheet at the pre-weakened area so as to form an outlet opening for the product through the first sheet. The first sheet has a U-shaped protuberance that extends from a side of the first sheet outside of the pocket and is arranged at the pre-weakened area.

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 sealed single-dose break-open package having: a first sheet of semi-rigid plastic material; a second sheet of flexible plastic material superimposed on and sealed to the first sheet of semi-rigid plastic material to define a sealed pocket containing a dose of a product; and a pre-weakened area, which extends transversely and is obtained in a central area of the first sheet, so as to guide, following a folding of the sealed package, a controlled breakage of the first sheet in correspondence to the pre-weakened area; the pre-weakened area has a single inner incision, which is oriented transversely and is obtained through an inner surface of the first sheet, and a single outer incision, which is oriented transversely, is obtained through an outer surface of the first sheet, and is transversely staggered relative to and longitudinally aligned with the inner incision.
