In a method of applying a cap having a top 1, gasket holding rib 2, skirt 3, and bead 4 to a container 5 having a multi-start continuous thread around its mouth, the cap is first placed on the container so that its skirt snugly embraces the thread form and then the whole circumference of the bead 4 is pressed inwardly by projections 11 on fingers 12 actuated by wedge-shaped fingers 13 into engagement with the thread form, the cap meanwhile being pressed downwards by a pad 10.
