Abstract: A closure (1) comprises an attachment member (10) for releasably attaching the closure to a container (2), a cover member (20) for extending over an open top of the container, and a handle member (30). The open top of the container terminates at a peripheral lip (3). The attachment member (10) also comprises a closed loop (22, 25) having a flexible loop portion (22) which, in use, is contractible to secure the loop to the lip and to thereby attach the closure to the container. The cover member has a first edge portion which is attached to the attachment member, and a second edge portion which is opposite the first edge portion and is attached to the handle member. The cover member also comprises an elastic portion (21) which is contractible to draw the opposite edge portions of the cover member toward one another. The handle member has a hand grip portion (31) for manipulating the cover member.
