A tamper-evident closure including a cap having a base and an upstanding post, the base defining a circular channel. A spout is positioned on the upstanding post, with the spout carrying a circumferential skirt permanently retained in the circular channel. A frangible line of weakness permits separation of the spout from the circumferential skirt. The spout and circumferential skirt are of a color that contrasts with the color of the base and post, so that, upon movement of the spout on the post, the circumferential skirt remains in the channel to provide a visual indication of such movement.

[ We claim:] [1.] A tamper-evident closure comprising, a cap for a container, said cap including a base and an upstanding post, said base defining a generally U-shaped circular channel having side walls and a bottom, said bottom lying entirely within the base, and a spout positioned to enclose said upstanding post, said spout carrying a circumferential skirt press fitted into said channel to prevent any relative movement between said skirt and base, and a frangible line of weakness between said spout and said skirt permitting separation of said spout from said skirt, said skirt being of a color different from said base whereby upon separation of said spout, said skirt remains gripped in said channel serving as a colored ring indicator of such separation.
