ABSTRACT:
This relates to an easy opening container unit wherein a panel of a container is provided with a first line of weakness defining a first displaceable panel portion which, when displaced, defines a dispensing opening in the container. A second line of weakness extends from the first line of weakness and defines a second displaceable panel portion to which an opening tab is secured with the second displaceable panel portion functioning as a hinge element for the opening tab. the arrangement of the lines of weakness permits the use of a substantially rigid tab which permits a greater leverage advantage while at the same time minimizing tab failure.
