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.
Claims5
A method for making a weakening in a sheet of semirigid plastic material, the method comprising the steps of:
- making at least one substantially straight first incision at a first edge of the sheet;
- making at least one shaped incision in a central portion of the sheet, laterally and at a distance from the at least one substantially straight first incision;
- forming the incisions by plastic deformation of the material of the sheet;
- making the incisions by moving a first plate connected to an incision tool having at least one protrusion from a first position far from an opposite plate to a predetermined position near to the opposite plate to produce the plastic deformation in the sheet placed between the first plate and the opposite plate.
