Tamper-evidence for a product casing

Abstract

A tamper-evidence for a product casing (103), comprising the product casing (103) made from a packaging material; at least a first longitudinally shaped tearing zone (204) comprising structures embossed in the packaging material, the at least one first longitudinally shaped tearing zone being located on a surface of the product casing and defining a delimitation of a lid area (202) on the surface of the product casing; an opening strip (200) made of a foil material, the opening strip being configured to adhere on the packaging material of substantially the entire lid area, to cover the at least one first longitudinally shaped tearing zone in order to seal it, and to produce a tearing of the packaging material corresponding to the at least one first longitudinally shaped tearing zone on the product casing and a removing from the product casing of packaging material of the lid area, as an effect of the opening strip being pulled away from the product casing and further comprising a second longitudinally shaped tearing zone (205) parallel to the first longitudinally shaped tearing zone, and wherein the lid area (202) is delimited by the first and second longitudinally shaped tearing zones and a border of the packaging material.

         11 . A tamper-evidence for a product casing, comprising
 the product casing made from a packaging material;   at least a first longitudinally shaped tearing zone comprising structures embossed in the packaging material, the at least one first longitudinally shaped tearing zone being located on a surface of the product casing and defining a delimitation of a lid area on the surface of the product casing;   an opening strip made of a foil material, the opening strip being configured
 to adhere on the packaging material of substantially the entire lid area, 
 to cover the at least one first longitudinally shaped tearing zone in order to seal it, and 
 to produce a tearing of the packaging material corresponding to the at least one first longitudinally shaped tearing zone on the product casing and a removing from the product casing of packaging material of the lid area, as an effect of the opening strip being pulled away from the product casing; and 
   the tamper-evidence further comprising a second longitudinally shaped tearing zone parallel to the first longitudinally shaped tearing zone, and wherein the lid area is delimited by the first and second longitudinally shaped tearing zones and a border of the packaging material.   
     
     
         12 . The tamper-evidence of  claim 11 , in which the opening strip is further configured to also adhere to the at least one longitudinally shaped tearing zone. 
     
     
         13 . The tamper-evidence of  claim 11 , in which the opening strip comprises a boundary zone that extends beyond the at least one longitudinally shaped tearing zone over a border zone of the packaging material separated from the lid area by the longitudinally shaped tearing zone, and is configured to removably adhere to the border zone by means of a re-sealable adhering system. 
     
     
         14 . The tamper-evidence of  claim 13 , in which the product casing is contained in a product box, the product box comprising a hinged lid covering the lid area when closed, and where the opening strip is attached at one of its borders to the hinged lid and configured to be pulled away from the product casing when the hinged lid is opened. 
     
     
         15 . The tamper-evidence of  claim 11 , further comprising glue configured to realise the adhering of the opening strip on the packaging material. 
     
     
         16 . The tamper-evidence of  claim 11 , wherein the embossed structures are laid out in sequence in at least one groove extending in the longitudinal direction of the longitudinally shaped tearing zone, the groove having a depth of at least a half of a thickness of the packaging material. 
     
     
         17 . The tamper-evidence of  claim 11 , in which the embossed structures are shapes that protrude in the packaging material in a direction away from the opening strip. 
     
     
         18 . The tamper-evidence of  claim 11 , in which the embossed structures are openings pierced through the packaging material. 
     
     
         19 . The tamper-evidence of  claim 11 , in which the structures embossed are at least in part positioned in the tearing zone to be aligned with a periodicity in a range from 0.5 mm to 5 mm, hence being configured to produce an audible sound of determined frequency when the opening strip is being pulled away from the product casing. 
     
     
         20 . The tamper-evidence of  claim 11 , in which the opening strip further comprises a grip element configured to be seized to pull the opening strip away from the product casing.
