<P>PROBLEM TO BE SOLVED: To provide a cap with a tamper-proof ring free from any troubles that a cap unsealing annular band is detached, and a cap body is lost while the cap is unsealed, or other cap is mistakenly screwed to a spout, and easy in separate collection during the disposal. <P>SOLUTION: The cap comprises a cap body 100 having a female screw on an inner circumferential surface from the top, an unsealing annular band 120 having an unsealing knob part 121 on an unsealing start tip in the transverse direction, and a fitting ring 130 having a spout 200 and a slidably rotatable engagement ring 222. A rear lower end of the cap body and an opposing upper end of the fitting ring are connected to each other by a connection band which is bendably narrow, thin-walled and vertical. The unsealing annular band is connected between the cap body and the fitting ring on both sides of the connection band, an upper end of the unsealing annular band is connected to a lower end of the cap body via an annular easily-breaking line 242, and a lower end of the unsealing annular band is connected to the upper end of the fitting ring via the annular easily-breaking line. When the cap is fitted to the spout by a plugging method, a lower tip of a female screw 114 of the cap body cannot be screwed to an upper tip of a male screw 221 of the spout. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
