Definitions

  • the closure 80 When the closure 80 is opened as shown in Figure 3, the closure 82 is forced to open about its connection 83 and because of the separation between the hinge 81 and the connection 83, the neck of metal joining the tab 82 and the connection 83 will be displaced below the surrounding metal of tab 80 and the can end to create a passageway 84 which acts as an air vent during the pouring or drinking operations. This improves the pouring and drinking characteristics of the end, especially the drinking characteristics in the event that the user's mouth substantially covers the pouring opening.
  • the can end is formed with a fully sheared closure member or tab 90 which overlaps with and underlies the metal surrounding the opening in the same manner as tab 80.
  • the tab 90 is hinged to the end about 91 and a small non-resealable pressure releasing closure tab 92 is formed over the hinge line with part of the tab 92 projecting into the tab 90.
  • the tab 92 is formed in basically the same manner as tab 82 only it is hinged to end about 93 in such a manner that the metal defining the connection permanently deforms when the tab 92 is opened to release the pressure within the can.
  • the tab 92 is still further opened as in the preceding embodiment to create a permanent venting passage for the pouring/drinking operations.
