Definitions

  • the present invention relates to a closure lid for an easy-open container.
  • the invention provides a closure lid for a so-called easy-open container intended to contain any type of packaged food, the container being of the type that is formed by a metal body, in particular cylindrical-shaped, and a closure lid initially integral to the container, the opening of which is carried out by pulling a pull-ring arranged on the visible face of said lid and fixed thereto by a rivet.
  • Containers commonly known as “canning tins” equipped with an easy-open system are well known.
  • These easy-open opening systems usually consist of a lid that is detachably attached to the container thanks to a cut line designed to weaken it and that has a pull-ring on its visible face that allows the lid to be angularly separated, exposing at least part of the content thereof.
  • the need to pull the pull-ring entails first applying a force to partially separate said pull-ring from the surface of the lid and, secondly, an upward pulling force on the pull-ring that allows dragging with it the lid itself in order to separate it from the body of the container.
  • the upward pulling force on the pull-ring it depends not only on the resistance of the cut line on the periphery of the region where the lid is attached to the container, but also on the design of the rivet itself, since opening the lid is usually facilitated by the lever force made by one extremity of the pull-ring in the rivet region on the body of the can, therefore limiting the angle at which the pull-ring is pulled to approximately 22°.
  • the present invention solves the aforementioned disadvantages of the already known canning tins, providing a closure lid for a so-called easy-open container intended to contain any type of packaged food where essentially the special shape of the rivet that attaches the pull-ring to the lid allows an easy opening with a greater ring lifting angle and without risk of detachment thereof.
  • the container is of the type that is formed by a metal body, in particular cylindrical-shaped, and a closure lid initially integral to the container, the opening of which is carried out by pulling a pull-ring arranged on the visible face of said lid and fixed thereto by a rivet.
  • the closure lid of the present invention is of the type that has a pull-ring fixed to the lid of a metal container by means of a rivet.
  • Said pull ring essentially has a rounded wedge shape at its widest extremity and a trapezoidal shape at its opposite extremity, being attached via this trapezoidal extremity to the lid by means of a rivet.
  • the pull-ring has a likewise trapezoidal depression that presents a U-shaped weakening line that partially surrounds the circular rivet. Also at this extremity, the pull-ring has an essentially triangular projection, the vertex thereof defining the fulcrum of the pull-ring against the lid for opening.
  • This design of the pull-ring and rivet assembly of the lid of the invention allows opening at a 29o angle, significantly greater than that provided by the easy-open lids of the prior art, thus facilitating the opening of the container and avoiding the aforementioned drawbacks.
  • the closure lid (1) of the present invention is of the type that has a pull-ring (2) fixed to the lid (1) of a metal container by circular rivet means (3).
  • this trapezoidal pull-ring (2) essentially has a rounded wedge shape at its widest extremity and a trapezoidal shape at its opposite extremity, being attached via this trapezoidal extremity to the lid (1) by means of the rivet (3).
  • the pull-ring (2) presents a likewise trapezoidal depression including a U-shaped weakening line (4) partially surrounding the rivet (3). Also, at this extremity, the pull-ring has an essentially triangular projection (5) the vertex thereof defining the fulcrum of the pull-ring against the lid for opening.
  • the opening angle of the pull-ring is determined by the diameter (A) of the rivet (3) and by the distance (B) from the extremity (10) of the weakening line (4) to the tip of the pull-ring, which is the region that exerts the force on said weakening line to break the metal.
  • an intermediate region (C) between the rivet (3) and the tip of the pull-ring is deformed thanks to the weakening line and the geometry of the assembly.
  • the lid provided by the invention and in particular the pull-ring (2) and the rivet (3) assembly allows a greater opening than a conventional lid, such as at an angle of 29o compared to the 22o angle of a conventional lid, thereby facilitating the opening of the container and reducing the force needed to do so.
  • this distance (B') is 2.75 mm.
  • the diameter (A) of the rivet (3) is increased.
  • the lid of the invention has, in correspondence with the essentially triangular projection (5) whose vertex defines the fulcrum of the pull-ring against the lid, a concave recess (6) that facilitates the pivoting of the pull-ring extremity on the lid in order to further assist the opening.
  • said recess has a radius of 0.7 mm.
  • the rounded extremity opposite the rivet region of the pull-ring (2) forms an angle of 174° relative to the plane of the lid surface, thereby enabling an angle of 29° to be reached more quickly at the extremity of the tip of the pull-ring.
