Description

ABSTRACT:
A screw-on jar top having opposing ears formed from jar top side material and protruding above the edge of the top is disclosed, while the seal between the top and the jar is maintained. The ears are shaped to receive a leverage-applying member to permit easier opening of the top when it is tightly screwed on, and to permit stacking of jars without interference from the ears.
