Container and closure cap

A container (10) and a closure cap (1) therefor, the container (10) having a screw-threaded neck (11), the cap having an end panel (2) for closing the neck (11), an inner skirt (3) depending from the end panel (2) and having a screw thread (4) for co-operation with the neck thread (12), and an outer skirt (5) surrounding the inner skirt (3) and being resiliently connected thereto, one of the container and the closure having a locking ring (15) with at least one slot (16,17) therein, the other having at least one lug (7,8) which engages in a slot (16,17) when the cap (1) is fully screwed on to the container (10) and the outer skirt (5) is in a first, rest position, thereby preventing the cap (1) from being unscrewed, the outer skirt (5) is movable to a second position in which the resilient connection is stressed and in which the lug (7, 8) is disengaged from the slot (16,17) to allow the closure to be partially unscrewed until the lug (7,8) is aligned with the slot (17,16),

• characterised in that the locking ring is adapted to prevent movement of the outer skirt back to the first position during partial unscrewing such that when the lug (7,8) is aligned with the slot (17,16) the resilient connection urges the outer skirt (5) back to the first position and the lug (7,8) passes through the slot (17,16) due to axial movement of the inner skirt (3) during the partial unscrewing, thereafter the cap (1) can be fully unscrewed from the container (10).
