Production method for producing sealed break-open package and corresponding sealed break-open package

Abstract

A production method for producing a sealed break-open package (1) comprises the steps of making, through an outer surface (8) of a sheet (2) and by means of a first tool (14), an outer incision (7), which at least partially extends into the area of the pocket (4); and making, through an inner surface (10) of the sheet (2) opposite the outer surface (8) and by means of a second tool (16), an innerincision (9), which is parallel to and aligned with the outer incision (7). The inner incision (9) is made only after the outer incision (7) has been completed and by making the second tool (16) to perform a working stroke which brings a tip of the second tool (16) inside the outer incision (7).

[0001] Cross References to Related Applications [0002] This patent application claims priority from Italian Patent Application No. 102018000001307 filed on January 18, 2018, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a manufacturing method for manufacturing a sealed rupture package and a corresponding sealed rupture package. Background technique [0004] Patent application WO2009040629A2 discloses a sealed single-dose break-open package; the sealed package comprises a sheet of semi-rigid plastic material and a sheet of flexible plastic material superimposed on a semi-rigid plastic material sheet and sealed to the semi-rigid plastic material sheet to define a sealed bag containing a dose of fluid product. The sheet of semi-rigid plastics material has a central pre-weakened region for directing a controlled rupture of the sheet of semi-rigid plastics material in order to form an outlet openin...

AI Technical Summary

Problems solved by technology

[0005] The sealed single-dose package described in patent application WO2009040629A2 has an optimal function; however, because the two cuts (inner and outer) have to be made very precisely in order to avoid damage to the barrier layer and at the same time allow when the sealed package is bent into The semi-rigid plastic material sheet breaks immediately in the "V" shape, so its manufacture is more complex (i.e. it requires the use of very precise and perfectly adjusted notch units)
