A lid for a container comprises a groove for engagement with a rim of the container. The dimensions of the lid may be reduced sufficiently that the groove can be disengaged from the rim of the container without the use of a tool. An elastomeric section is moulded between two polypropylene sections such that when the recesses are squeezed together, the elastomeric section deforms and thereby allows a sufficient reduction in the diameter of the lid that the lid can be removed from the container without the use of a tool. A catch may be provided across the elastomeric section such that when the catch is in the closed position, the elastomeric section is prevented from deforming and the lid cannot be easily removed from the container.
