Definitions

  • the present invention refers to the technical field of the so-called easy open lids, which can be opened without using tools, particularly those comprising a lid with a weakening line and a hoop to pull from it, and more specifically, protection means used to avoid cutting the user's fingers when pulling from the hoop to remove the lid panel.
  • lid In the case of the so-called easy open cans, used for food products, their lid is usually made of tinplate, although it can be made of different materials, such as aluminum, and adopt different shapes such as circular, rectangular, oval, etc.
  • opening and removal from the can is usually made by means of a hoop in an area of the lid next to the edge and which is weakened due to a notch.
  • the hoop is riveted in the lid, and by an action, which is usually that of lifting said hoop, it rips the weakening area, the panel of the lid being later removed from the can by pulling from the hoop.
  • This opening system is very simple and convenient since it avoids the use of any kind of tools, but it has an important inconvenience, which is the risk of producing cuts in the user's fingers when opening the can.
  • the present invention solves the problems existing in the state of the art by means of an anticut protector for easy open lids, of the kind that has a lid with an area close to its edge which is weakened by a notch, and which is ripped when an effort is applied with an opening hoop riveted in the weakening area.
  • the anticut protector is formed by a belt made from elastomer, which is placed on top of the weakening area, protruding in at least part of the edge, from the panel, and covering said edge, at least partly, thus eliminating the risk of cutting the user's fingers with the part of the lid covered with said belt.
  • the belt is located along the entire length of the lid edge, said edge being thus covered in its entire length, thus eliminating the risk of cutting the fingers with the entire edge of the lid panel.
  • This protector can be applied to all kinds of easy open lids, of any shape, size and material, in which the edge of the lid panel can produce cuts in the user's fingers, such as tinplate lids.
  • the anticut protecting belt is made of heat-fusible plastic, being thus possible to easily mold it in any desired way to be placed in the lid weakening area, and once fixed, permanently stay at the edge, even after the lid has been removed from the can.
  • the anticut protector object of the present invention is applied in easy open lids, of any material, size and shape, of the kind having a lid 1 with an area next to its edge 3 weakened by a notch, which is ripped when an effort is applied with a pulling handle or opening hoop 2 riveted in the weakened area.
  • the lid 1 can be made of any material with an edge 3 that can produce cuts in the user's fingers, such as tinplate.
  • the anticut protector is a belt 4 placed in at least part of the lid 1 edge 3, and covers the edge 3 of said lid 1 at least partially.
  • the figures show a preferred embodiment of the invention in which the belt 4 is placed along the entire length of the edge 3 of said lid 1, thus covering said edge in its entire length.
  • the can and the lid 1 are circular, so the belt 4 covers the entire perimeter of the circumference.
  • the belt 4 object of the present invention is made from elastomer material, and preferably of heat-fusible plastic, which facilitates the molding of the material to adapt it to the size and shape of the lid 1, which once fixed can permanently stay at the edge 3 of the lid 1, even after the lid 1 has been removed from the can.
  • plastic materials such as silicon, hot melt, hot adhesives or paraffin.
