A container, for example a drinks can, which is made readily collapsible for disposal by providing grooves on the external (grooves 13A to 13E) and internal (grooves 16A to 16F) surfaces of the cylindrical wall (12) of the container. Each external groove (13A to 13E) meets a respective internal groove (16A to 16F) at their ends to form a zig-zag pattern of internal grooves/external grooves alternating around the whole circumference of the container. The container is collapsed by grasping the top and bottom ends with the hands and exerting a counter twisting motion, which causes the container to easily collapse upon itself into a small size for disposal.
