<p>A closure (30) for use, or in combination, with a member (10) defining an orifice, such as a container or fitment for attachment thereto, the closure comprising a first snap band formation (42) and the member comprising a second snap bead formation (18), the formations (18, 42) adapted to cooperate to provide a snap engagement retaining the closure with respect to the member while permitting at Least limited rotation with respect to the member. The closure further comprises a third ramped formation (44) interengageable with a fourth ramped formation (46) associated with the member upon the at least limited rotation, the interengagement of the third and fourth formations urging the closure to move axially away from the member and overcome the snap engagement. The third and fourth formations may be a recess and a projection. A tamper evident band may carry the fourth formation. The rotation may be permitted in one or both of clockwise and anticlockwise directions.</p> |
