Container for a substance, in particular a drink, with a tear-open closing element

A lid for a container able to contain a substance, comprising:

• a peripheral rib delimiting a central zone having a substantially circular shape with a determinate radius, concentric with respect to a central axis, solid with said peripheral rib and on which central zone an interrupted line of weakening is made, which line of weakening defines a pull-open closing element always integral with the remaining part of the central zone and provided with a front terminal part disposed next to said peripheral rib, which pull-open closing element functions as a removable stopper to a relative aperture for said substance to pass through, made in said central zone;
• and a lever, having a part connected to said closing element so that said lever can be driven to remove, at least partly, said closing element from the remaining part of said central zone, detaching said closing element along said line of weakening and thus putting said aperture in communication with the outside, said line of weakening being interrupted at one end of said closing element on the opposite side of said lever with respect to said central axis, so that said closing element has an edge solid with the remaining part of said central zone;
• wherein said lever comprises:
• a first end having a central part of the first end functioning as a fulcrum disposed in correspondence with said peripheral rib, outside said closing element defined by said line of weakening and in front of said front terminal part, said fulcrum being able to determine the lifting of said closing element by drawing;
• a second end opposite said first end and functioning as a gripper, lifting and drawing element, disposed in substantial correspondence with said central zone, wherein said first end and said second end are separated a little less than a length of said radius;
• and an intermediate zone between said first end and said second end, by means of said intermediate zone said lever being connected to said closing element, said intermediate zone of said lever comprising a flexible tongue mechanically connected to said closing element in the front terminal part thereof, to lift and detach said front terminal part of said closing element from the remaining part of the central zone, without any part of the closing element coming into contact with the substance contained inside the container and keeping the closing element always solid with the remaining part of the central zone.

A method to open a closing element of a container able to contain a substance, wherein said container comprises:

• an upper wall functioning as a lid, having a peripheral rib delimiting a central zone having a substantially circular shape with a determinate radius, concentric with respect to a central axis, solid with said peripheral rib and on which an interrupted line of weakening is made, which line of weakening defines said pull-open closing element always integral with the remaining part of the central zone and provided with a front terminal part disposed next to said peripheral rib, which closing element functions as a removable stopper to a relative aperture for said substance to pass through, made in said central zone;
• and a lever, having a part connected to said closing element so that said lever can be driven to remove, at least partly, said closing element from the remaining part of said central zone by drawing, detaching said closing element along said line of weakening, and thus putting said aperture in communication with the outside, said line of weakening being interrupted at one end of said closing element on the opposite side of said lever with respect to said central axis, so that said closing element has an edge solid with the remaining part of said central zone;
• wherein said lever comprises:
• a first end having a central part of the first end functioning as a fulcrum disposed in correspondence with said peripheral rib, outside said closing element defined by said line of weakening and in front of said front terminal part, said fulcrum being able to determine the lifting of said closing element by drawing, without said closing element going inside the container;
• a second end opposite said first end and functioning as a gripper, lifting and drawing element, disposed in substantial correspondence with said central zone, wherein said first end and said second end are separated a little less than a length of said radius;
• and an intermediate zone between said first end and said second end, by means of said intermediate zone said lever being connected to said closing element said intermediate zone of said lever comprising a flexible tongue mechanically connected to said closing element in the front terminal part thereof,
• said method comprises:
• lifting said second end of said lever rotating toward the outside of said peripheral rib, pivoting on said first end thereof that cooperates with said peripheral rib and acting externally to the closing element, so that said flexible tongue of said intermediate zone of said lever lifts and detaches the front terminal part of said closing element from the remaining part of said central zone, along said line of weakening, without any part of the closing element coming into contact with the substance contained inside the container and keeping the closing element always solid with the remaining part of the central zone;
• and
• pulling backwards said lever to lift said closing element and continue to detach said closing element along said line of weakening, keeping the closing element always solid with the remaining part of the central zone, until said aperture is opened.
