A tamper evident spouted closure, contains a base (1) supporting a pivotally mounted spout (4). A tab (7) is integrally connected to a pair of frangible webs (6) and those webs are serially integrally connected to the distal end of said spout, the webs and tab extending from the spouts end. A tab seat (10) is integrally formed in the closure base and a weld permanently joins the tab to the seat. The frangible web thereby obstructs the initial movement to lift and open the spout. When the spout is pulled open, the frangible web easily breaks. The broken web serves as visual evidence that the spout was previously opened and then re-closed.
