Abstract: A plastics closure (10) for a container is provided. The closure comprises a top plate (15), with a side skirt (20) depending from the periphery thereof. A sealing strip (45) depends from the top plate (15) and is adapted to sealingly engage a container neck finish (75). The closure (10) also comprises an abutment member (55) including a guide surface (65) for guiding the sealing strip (45) towards the neck finish (75) as the closure is applied, to increase the strength of the seal. The guide surface comprises a guide member (65) which projects from the abutment member (55), thereby minimising friction between the strip (45) and the abutment member (55). The sealing strip (45) is inclined radially towards the neck finish to improve the sealing effect.
