Abstract: A closure for a container (14) comprises a first portion (12) for mounting to the container and a second portion (10) adapted for mounting to the first portion. When the second portion is removed from the first portion it opens the container. When the first portion is mounted to the container and a deformable seal (66) is positioned therebetween, and when the second portion is then mounted to the first position, the seal is deformed and is simultaneously able to seal between the first portion and the container, and between the first portion and the second portion.

Abstract: A container (10) has a lid (12) for rotation mounting thereon. A tamper evident mechanism is located for operation between the container and lid. The mechanism includes at least one projection (42) on the container and at least one corresponding flange (44) on the lid. Each flange and projection pair is arranged such that, when the lid is rotation mounted on the container, the flange moves relatively past the projection to a position such that removal of the lid by counter rotation may only occur by deforming or breaking of the flange and/or projection.
