<P>PROBLEM TO BE SOLVED: To prevent a lid body from being unexpectedly opened even when coming into contact with another article, and in addition, to enable the opening motion to be extremely easily performed by a one-touch operation in a lid body lock structure which is suitable to be provided for any kind of beverage container such as a portable thermo-bottle. <P>SOLUTION: This lid body lock structure has a sliding lock member 41 which slides in the length direction along a fastening member 31, and an urging means 61 which urges the sliding lock member 41 and the fastening member 31 to the outside, on the internal side of the fastening member 31 which is pivotally attached to a main body section 14. At the same time, the sliding lock member 41 has an operation section 42 which projects to a position on the external side of the external surface of the fastening member 31, and rotation force transmitting sections 44 and 46, and a rotation regulating section 45. In this case, the rotation force transmitting sections 44 and 46 rotate the fastening member 31 in the direction by which the fastening of the fastening claw 32 is disengaged when the operation section 42 is rotated by being pressed to the inside. The rotation regulating section 45 prevents the rotation of the sliding lock member 41 from occurring by coming into contact with or approaching a part 55 of the main body member 14 when being slid to one side in the length direction of the fastening member 31 by sliding the sliding lock member 41. <P>COPYRIGHT: (C)2007,JPO&INPIT |
