Abstract
A container end member has a peripheral wall and integral central end wall portion with a stay-on-tab mounted on the central end wall portion for pivotal and rotational movement and a score line groove defined by two spaced apart terminal ends formed in the central end wall portion for defining a severable panel portion that is large enough so that when severed will provide an elongated opening that vents the container to permit pouring of the beverage in the container at faster pour rates than now available.

A container end member for sealed association with a container body member to provide a sealed container comprising:
- a container end member having a peripheral wall portion and an integral, central end wall portion;
- a stay-on-tab;
- mounting means for pivotally and rotationally mounting said stay-on-tab on said central end wall portion;
- a score line groove defined between two spaced apart terminal ends formed in said central end wall portion for defining a severable panel portion;
- said stay-on-tab having one end portion for applying a force on said severable panel portion to move said severable panel portion into said container;
- said severable panel portion having a size that requires the application of force by said one end portion on at least two spaced apart locations of said severable panel portion to pivot said severable panel portion around a first hinge to open partially said severable panel portion and then to pivot said severable panel portion around a second hinge to sever completely said score line groove;
- said second hinge retaining said stay-on-tab on said container end member;
- said first hinge being adjacent one terminal end of said score line groove, the second hinge being adjacent the second terminal end of said score line groove and said first and second hinges being spaced apart.
