Definitions

  • the opening systems for cans containing drinks, or contents of any kind , which are actually in use, belong to one of two different types:
  • the present patent for industrial invention proposes a system for opening cans which prevents both these disadvantages.
  • the solving idea proposed for this pended is illustrated on table 1/1 in figs. 1, 2 and 3 in which the axial view of tbe can and two views of the same can from the upper side are respectively represented, the pulling ring beeing turned inside in fig.2 and outside in fig 3.
  • the upper side of the can has been provided with two punch-pressed stops 1 and 2 and with two pre-pressed opening traces 3 and 4; at the starting point of these traces, near to the border of tbe can has been placed the opening ring 5.
  • the pulling ⁇ ng 5 is pivotted in posiuon 7 and it can be turned in such a way as to assume the different positions illustrated in figs. 2 and 3.
  • Tins allows for the tab to be stripped from two positions: a) as shown in picture 2, leaving the opening ring o ⁇ ented towards the center of the can cover, in the same position that it o ⁇ ginally is in to allow a convenient assembling of cans for production and dist ⁇ bution. b) as shown in picture 3, where tbe ⁇ ng (designed with the nght thickness and structure) has been rotated 180° on tbe border of the cover, lo facilitate its g ⁇ pping To achieve a better flowing of the liquid from the can after opening, a slightly concave shape can be given to the border of the can along zone 8 From this desc ⁇ puon and from the enclosed illustrauons the following advantages of this invention clearly result
  • the tab remains pe ⁇ nanentely connected to the can without representing in any way an obstacle for the liquid being poured, hence with no possibihty for the tab to come in contact with it - inverting the sequence of the opening movements, the tab can be placed back into its o ⁇ ginal position, covering the outlet for better preservauon of a residual content suit in the can
