Disclosed is a can opening structure which can smoothly cut open a smiling mouth shape having a wide but sharp curve, which cannot be achieved by existing can openings with a narrow width. The can of the present invention comprises: a plurality of detached and protruding pressing portions that are separately provided for cutting open a discharge port stopper with the smiling mouth shape having the wide width and sharp curves at the edges; and welded protrusions for securely activating specific pressing portions first; wherein the distances (34-A, B, C) from the area pressed by a discharge port cover corresponding to each of the pressing portions to a closest spot on a predicted cutting groove are differentiated. Of course, the spot which should be set as in the closest distance is the spot (34-A) that is closest to one of the edges of the mouth from which the initial fracture begins. In the can of the present invention, the initial fracture begins near the left edge of the mouth, and the shearing of the right mouth portion is delayed while being completely uncompressed until the shearing of the cutting groove continues by means of tilting an opener up to before completing the sharp curve of the left edge of the mouth (before the left edge of the mouth is completely cut open). As a result, when one of the sharp curves of one side of the edge of the mouth is securely cut open, the rest of the cutting open process can be can be smoothly achieved with little effort, and ultimately, a user can securely open a can discharge port stopper with the smiling mouth shape having a wide horizontal opening width even with a simple action of tilting the can opener as with existing cans. ??? ??? ? ??? ??? ? ?? ?? ??? ??? ?? ?? ? ??? ???? ??? ? ?? ? ?? ??? ????. ? ??? ?? ?? ?? ??? ???? ??? ?? ?? ???? ???? ???? ??? ?? ?? ?? ?? ??? ????, ?? ????? ???? ?? ?????? ?? ???? ?? ??? ?? ???, ? ???? ???? ??? ??? ????? ????? ?? ?? ??? ????? ??(34-A,B,C)? ??? ???. ?? ?? ?? ??? ??? ???? ? ??? ?? ??? ???? ?? ?? ? ????? ?? ??? ??(34-A)??. ? ??? ?? ?? ? ???? ???? ?? ??? ????, ?? ??? ???? ?? ???? ??? ???? ?? ? ????? ??? ??? ??? ????? ???(?? ???? ??? ?????? ???), ??? ? ??? ???? ? ????? ?? ????. ??? ?? ?? ???? ??? ??? ??? ?? ???? ?? ??? ????? ?? ???? ???? ????? ????? ???? ??? ?? ?? ??? ? ?? ??? ?????? ?? ? ??? ?? ?????? ?? ? ?????? ???? ??? ? ??. |
