Abstract
The purpose of the invention is to provide a very safe opener cap that can easily open a film serving as a section to be opened without scattering the contents. A can body (10) and a screw cap (20) are screwed together, and the screw cap (20) and an opener (30) are ratcheted together so as to rotate as a unit in the direction of the screw cap (20) tightening. Blade angles of an annular blade (34) are configured so that the blade angle in the direction of the screw cap (20) loosing is gentler than the blade angle in the direction of tightening.
