PROBLEM TO BE SOLVED: To provide an excellent cap formed of a cap body and a lid plate arranged thereon in an openable manner with which a lid can be easily opened and closed with one hand which is holding a container and assembling operation can be done with a comparatively simple structure. SOLUTION: In a cap body 2, through holes 8 are punched in a front part of a top wall 7 and a recess 9 whose top face and back face are opened are recessed at the back part. A lid plate 3 is pivotally and rotatably attached to an upper part of inner face front parts of both side walls of the recess 9 and is arranged in an openable manner for blocking the through holes 8. A presser plate 4 is arranged at the back of the recess 9 in a manner rocking back and forth. The head end part of the front face of the presser plate 4 is connected to the back end edge of the lid plate 3 in a bendable manner through a thin hinge 21, and a connecting rod 5 including an elastic lateral cylindrical part 22 which crosses the middle part is provided. While the elastic lateral cylindrical part 22 is compressed and deformed by push of the upper part of the presser plate 4, the connecting rod 5 rotates and the lid plate 3 erects reversely. |
