Abstract
The present application improves the shape of a curl part of a bottle can to secure high sealability even under high pressure in the can and during heat sterilization, makes bubbling-over occur less during cap opening, and suppresses misrecognition of reseal. A bottle can has a curl part provided at an opening end of a mouth part. The curl part includes an outer wall part extending downward from an upper end bent part. The outer wall part includes a first bent part shaping a locking part that extends continuously and downwardly from the upper end bent part and shapes an outwardly-protruding convex, and a second bent part that extends continuously and downwardly from the first bent part and shapes an inwardly-protruding convex.
