A rack with a rack body and a releasable locking portion holds two or more drinking vessels. The rack body includes a first and second locating devices, and a capture device to releasably capture the releasable locking portion. The releasable locking portion includes a first engagement device to engage with the capture device, and a second engagement device to engage with a second sector of each vessel base such that each vessel is prevented from moving in two perpendicular directions as a consequence of interaction between the vessel base, the second engagement device, and the first locating device, and is prevented from moving in a third perpendicular direction as a consequence of interaction between the second locating device and the upstanding portion.
