<p><P>PROBLEM TO BE SOLVED: To provide a cap which can be easily opened in unsealing by cutting a breaking bridge between a cap body and an unsealing history expression band, can be reclosed without excessive closing, and facilitates visual confirmation of unsealing history even in releasing. <P>SOLUTION: The unsealing history expression band includes a slit extending from the upper end to the lower end thereof. The unsealing history expression band is connected to the lower end of a skirt by a connecting bridge in the vicinity of the front side in a rotating direction in unsealing of the slit, and by the breaking bridge in the other part, and a protrusion is formed at the upper end on the rear side in the rotating direction in sealing of the slit of the opening history expression band. A recess is formed at the lower end of the skirt part to be meshed with the protrusion. Outwardly protruding projections each composed of a gentle slope to the front side in the rotating direction in sealing and a shape slope to the rear side in the rotating direction in sealing are vertically extended on the outer circumferential surface of the skirt part to form a turret. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
