A reclosable can top closure (4) includes a fixed insert (8) having a pouring aperture, and a twist-to-open closure element initially installed in the aperture. Breakable tamper-indicating means (10) connect the closure element to an anchor (7) attached to the insert, or to the top of the can. After the can has been opened, a flexible tether (5) prevents the closure element from being lost or discarded. |
