Abstract
PURPOSE: To surely maintain an air-tightness of can opening in case that a cap being set there and to prevent any possible decrement on setting force between them caused by external force, by constituting a conically rising part around the can opening by raising up a periphery of the opening after constituting a flat part at the top plate of a can.
CONSTITUTION: After a vertically rising part having an opening port 8 at a predetermined location of can top plate 7, such vertically rising part is then outwardly from above to the lower direction and further bent so as to directly form a flat part 9a' extending inwardly. Then, a conically rising part is constituted by raising up the periphery of the opening. An uppe wall plate 11a is capable of being freely placed inside as well as outside of the opening and a circular plate packing 12 is set at the inside of a cap 11 equipped with elastic hooking part having a plurality of elastic hooking parts 11b at regular intervals around its periphery wall. Each bottom end of elastic hooking parts 11b is set on an external surface of the flat part 9a' so that the cap can be fitted with inside of the opening by closely contacting the bottom surface of the packing 12 to an upper end of the flat part 9a'.
