ABSTRACT:
A lever lid and ring assembly, for a container body, has a tamper indicating sealing member which bridges the joint between the lid and ring. Various shapes of sealing member are described which are cut from aluminium foil coated with a hot melt adhesive. The seals are adhered to an external surface of the ring, and if the shape requires it, they are also sealed to the lid. In an alternative embodiment the sealing member is an annulus of plastics material extruded to seal the joint between the lid and ring.
