<p>The present invention relates to an opening construction of a can of aluminum or iron for storing beverage therein (high or low carbonated beverage), which comprises an easy-to-open stopper for a beverage can. The characteristic feature of the present invention is that, in a can formed of a body and a lid at the top, the lid has a protrusion, that is, an elevated part of a certain shape to prevent depression; a stopper formed inside the protrusion to open at need; a pressure surface which is connected with the risen surface of the protrusion at either one side, in a body, and slants gradually the lower as it approaches the center of the protrusion finally to join the stopper; a first incision groove, formed between the protrusion minus the pressure surface and the stopper, to cut at a pressure from outside; a first bending section, starting at the pressure surface to extend to one end of the stopper; a bending groove formed at the first bending section made to bend at one end when the pressure surface is pressed downward; and a second bending section, which bends when one end of the stopper is bent by the bending groove.</p> |
