<P>PROBLEM TO BE SOLVED: To provide a bottle to be opened single way in which the number of component parts is less to cause its volume to be reduced, its handling can be easily performed and an anti-external force characteristic can be improved even if the bottle is applied to a direct-drinking structure. <P>SOLUTION: This bottle comprises a metallic vacuum double container 1, a plug member 5 installed at its opening part 1a and having a direct-drinking port 14 risen from a top plate 5c and a single-opening lid 7 opened or closed around a hinge joint 10 at one side of the top plate 5c in respect to the direct-drinking port 14. In order to cause at least the upper end of the direct-drinking port 14 to be displaced and positioned at a counter-hinge joint 10 of the top plate 5c, facilitate drinking, and solve the problem, at least ultrasonic welding, adhesion and forced fitting is applied between at least the rising base portion of the direct-drinking port 14 of the top plate 5c and the hinge joint 10 to make a double-wall part 30 with integral formation of another member 56. <P>COPYRIGHT: (C)2008,JPO&INPIT |
