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.

An opener cap comprising a combination of a screw cap including a female screw to be joined with a male screw formed in a side-surface upper part of a can main body and an opener including an annular blade for cutting a film serving as a section to be opened and sealing an upper lid in which an opening of the can main body is formed, the opener being formed to remain in the opening of the upper lid after opening of the film, wherein
- upper ratchet teeth are formed at an opening end of a cylinder rib formed on a top plate rear surface of the screw cap and lower ratchet teeth are formed at an opening end of the opener on an opposite side of the annular blade such that the upper ratchet teeth and the lower ratchet teeth mesh with each other only in a tightening direction of the screw cap.
