Abstract

A tab main body section (520) is provided with first to third main body section slits (731-733) which penetrate through the tab main body section (520). The first to third main body section slits (731-733) are formed in a circular arc shape so as to extend along the outer peripheral edge of an insertion hole (540) formed in a circular shape. The first main body section slit (731) is provided between the insertion opening (540) and a first edge section (501) of a tab (500). The second main body section slit (732) and the third main body section slit (733) each have one end section (751) and the other end section (752). The one end section (751) is located closer to a second edge section (502) of the tab (500) than the insertion hole (540).

Dependent claims

A can lid comprising:

a panel that includes an outer peripheral edge and is attached to an aperture of a can barrel;
a tab that includes a first edge section, a second edge section on a side opposite to the first edge section, a first side edge formed to head for the second edge section from the first edge section, and a second side edge formed to head for the second edge section from the first edge section and arranged on a side opposite to the first side edge, the tab being operated by a user, when an opening is formed in the panel, to move in a direction in which a first edge section side is apart from the panel;
and
a connecting section that connects a portion of the tab positioned between the first edge section and the second edge section and the panel,
wherein the tab is provided with:
a first through hole that is provided between the first edge section and the connecting section;
a second through hole that is formed to include one end section closer to a side, on which the second edge section is provided, than the connecting section, and is formed to pass between the connecting section and the first side edge and also between the first through hole and the first side edge to head for the first edge section side from a location where the one end section is positioned, the second through hole being formed so that at least a part thereof heads for a second side edge side and an other end section is located in a region positioned between the first through hole and the first edge section;
and
a third through hole that is formed to include one end section closer to a side, on which the second edge section is provided, than the connecting section, and is formed to pass between the connecting section and the second side edge and also between the first through hole and the second side edge to head for the first edge section side from a location where the one end section is positioned, the third through hole being formed so that at least a part thereof heads for a first side edge side and the other end section is positioned in the region located between the first through hole and the first edge section, and
wherein the tab is further provided with an insertion hole for connecting the tab to the panel,
the first through hole is provided on a side closer to the insertion hole than the second through hole, and
the first through hole is provided on a side closer to the insertion hole than the third through hole.
