ABSTRACT:
A container assembly for packaging nonliquid material includes a can body that may be filled with nonliquid material and an end panel that is secured to the can body, preferably by seaming. A score line that is formed in the end panel defines a first removable portion and a second nonremovable portion. Structure such as a tab is provided for initiating separation of the first removable portion from the second nonremovable portion at a first location along the score line that defines an axis of symmetry about which separation of the first removable portion from the second nonremovable portion during opening will progress substantially symmetrically. The score line is shaped so that the second nonremovable portion defines a spoon leveling shelf that is shaped and sized to permit a consumer to level a spoonful of nonliquid material. Moreover, at least one exposed edge of the spoon leveling shelf is afforded cut protection by a safety fold.
