<P>PROBLEM TO BE SOLVED: To provide a container lid, in which a breakable thin-walled line (14) formed on the blocking wall (12) of an inside plug (4) is designed to be broken by turning an outside cap (6) in the opening direction to disconnect the outside cap from the inside plug to satisfactorily ensure breakability, the prevention of the falling of a region to be removed by breaking, the long and thin shape of the region to be removed, easy manufacture and the prevention of breaking the breakable thin-walled line in fitting the inside plug with the outside cap. <P>SOLUTION: At least one locking protrusion (42a, 42b, 44a, 44b) projecting downward is formed on the bottom surface of the top wall (34) of the outside cap. The locking wall (28) of the inside plug is provided with means (30, 32) to be engaged, and the locking protrusion is provided with engaging means (46). When the outside cap is turned in the opening direction against the inside plug, the engaging means and the means to be engaged cooperate to prevent the locking wall from moving in the direction of the axis against the locking protrusion and also to prevent the locking protrusion from turning in the closing direction relatively against the locking wall. <P>COPYRIGHT: (C)2013,JPO&INPIT |
