Claims

[Scope of utility model registration request]

A score line forming an annular or substantially annular lid is engraved on a part of the end panel of the can, a tab is fixed to the end panel near the score line, and the trigger side of the end of the tab is engraved. When the tab is raised, the tab is opened and expanded using the fixation point with the end panel as a fulcrum, and the pressure contact portion at the tip from the fixation point is pressed against the end panel, thereby applying a shearing force between the inside and outside of the score line and scoring. Breaking the open state of the can container by creating a crack in the line, and further causing a trigger at the end of the tab to increase the crack along the score line of the end panel to open the lid. A tab that facilitates opening of a can, characterized in that the tab has a bent part formed between a pressure contact part and a raising part of the tab so that the tab can be bent in the raising direction when the tab is raised.
