<p>A liquid container closure (1) having an internally screw threaded skirt (1a) including a tamper band (2); a drinking spout (4) having a push-pull cap; an overcap with an annular skirt adapted to completely cover the cap releasably securable to the closure or cap, the annular skirt including at its lower extremity an inwardly extending protrusion co-operating with an outwardly projecting protrusion at the closure shoulder (12) to releasably secure the overcap on the closure, a second tamper band frangibly attached to the skirt and including ramped teeth interacting between the band and the closure shoulder (12) permitting one way rotation but preventing opposite rotation. The shoulder (12) includes an upstanding wall spaced radially outwardly from the tamper band to permit the teeth to ride over each other during assembly of the overcap but not so as to facilitate insertion of objects under the tamper band between the tamper band and closure.</p> |
