Patent ID: 7775386

Claim:
A container comprising a neck and a cap, an abutment arrangement projecting from said neck, said cap comprising a base body and an opening indicating element connected to said base body by means of bridge elements intended to be fractured at the first opening of the container, said opening indicating element being provided with a flap arrangement comprising at least one first portion and at least one second portion arranged alongside one another along a peripheral edge of said opening indicating element, said at least one first portion comprising a first active surface suitable for interacting with a first face of said abutment arrangement generating a tensile stress that promotes the breakage of said bridge elements when said cap is removed from said neck, said at least one second portion comprising a second active surface suitable for interacting with a second face of said abutment arrangement so as to prevent rotation of said opening indicating element integrally with said base body, said interaction between said second active surface and said second face subjecting said bridge elements to a shearing stress that promotes the breakage of said bridge elements when said cap is removed from said neck.
