CAP STRUCTURE OF CAN FOR ENHANCING OPENING PERFORMANCE

摘要

PURPOSE: A cap structure of a can is provided to raise the grip part apart from forming a space on top side of the can sufficient to insert fingers in the space by adopting a specific grip part for the cap structure formed of metallic pieces having different heat-expandable properties. CONSTITUTION: The can comprises a tap connected to top portion(10) and a rivet(20); a score(50) which is opened by a cut-slit(40) by pulling down the tap. The tap is formed of at least two metal pieces having different heat expandable properties by coupling the pieces to the rivet(20), and bent at constant angle depending on temperature of content in the can. The tap comprises first taps(31a) and second taps(32a) coupled to top side of the first taps and having smaller heat-expandable coefficient than the first taps to be bent when the content in the can reaches constant temperature higher than room temperature.
