Opening means for a container

Abstract

In a can there are provided a number of weakening lines (1) in the body, the lid or the bottom, said weakening lines defining an opening section (2) intended for being rolled up or drawn away. In the opening section (2) there is arranged a perforating panel (3) being partly surrounded by three, rectilinear weakening lines at a distance from a weakening line (5 or 6) dependent on the form of the opening tool (4), said perforating panel (3) being arranged to be pressed into the interior of the can at the beginning of the opening operation. The panel is depressed by a beak (7) of the opening tool (4), whereby an admission aperture is formed permitting the insertion of a lobe (8) provided with an active point (14) at the end of the tool (4) pointing away from the beak (7). From the interior of the can the point (14) is pressed upwards through an initiating weakening (5), and the opening tool (4) is then rolled across the opening section (2) while rolling it up in the usual manner. The beak (7) is guided by a cavity (10) in the panel (3), whereby there is formed a well-defined, sharp-edged admission aperture for the lobe (8). Thereby the tool (4) is guided safely during perforation of the initiating weakening (5) and during rolling up of the opening section (2).
