Storage containers

A storage container comprising:

• a storage box defining a hollow storage volume, and a loading aperture for enabling access to the storage volume, and having a base portion opposite the loading aperture;
• and
• a closure member having a plurality of rotatable wheels located thereon, and having an open side and a closed side, with edge regions extending therebetween, the closure member being adapted for releasable engagement with the storage box,
• wherein the storage container has a first configuration, in which the base portion of the storage box is in contact with a supporting surface, and in which the loading aperture of the storage box is adjacent the open side of the closure member, such that the loading aperture is closed by the closure member,
• wherein the storage container has a second configuration, in which the wheels located on the closure member are in contact with a supporting surface, and in which the loading aperture of the storage box is adjacent the open side of the closure member, such that the loading aperture is closed by the closure member,
• wherein the storage container has a third configuration, in which the wheels located on the closure member are in contact with a supporting surface, and in which the base portion of the storage box is adjacent, and supported by, the open side of the closure member, such that the loading aperture is open, and
• wherein the open side of the closure member has a convex curved profile, and wherein the storage container has a fourth configuration in which the base portion of the storage box is adjacent, and supported by, the closed side of the closure member, and in which the convex curved profile of the closure member engages with a supporting surface, thereby allowing the storage container to rock.
