Abstract: An apparatus for facilitating movement of a closure (20) away from a part of a support (22,24) for the closure (20), the apparatus comprising: a bias component (26) engageable with the support (22,24) and closure (20); and an engagement component (28) engageable with said support (22,24) and closure (20); the bias component (26) when in a first state being arranged to bias a part of said closure (20) into engagement with a part of the engagement component (28) and to retain the closure (20) relative to that part of the engagement component (28), and the bias component (26) when in a second state, in which the bias is at least partially overcome, facilitating at least partial disengagement of the closure (20) from the part of the engagement component (28), to allow the closure (20) to be moved away from that part of the engagement component (28).
