ABSTRACT:
An easy open ecology end is disclosed herein and includes an end panel that has a removable section defined by a weakened score line. A tab is secured to the removable section and the tab and removable section are designed so that both remain captive with respect to the end panel when the weakened score line is severed. The weakened score line is produced by a unique three step process and has an area of reduced residual which is first severed when a force is applied to the tab so that the container is vented before the remainder of the residual is severed. The tab is designed to produce a localized initial pressure to initially sever the area of reduced residual and then sever the remainder of the score line.
