An unsealing label 30 having a peeling display function is pasted across the projection face 17 of the inner stopper 3 and the outer surface of the top wall 7 of the cap body 2. Upon uncapping, the unsealing label 30 is peeled off the projection face 17 to automatically display a mark of an unsealing notice, prize, etc. <P>COPYRIGHT: (C)2007,JPO&INPIT |
