<p>A push-and-turn container and closure cap combination provided. Cap (1) has an inner skirt (3) with H (10) is a screw thread (4) which co-operates with a screw threaded neck (11) of the container, and a sprung outer skirt (5) which surrounds inner skirt (3). Container (10) has a locking ring (15) with two slots (16,17); cap (1) has two lugs (7,8) which engage in slots (16,17) when the cap (1) is fully screwed on to the container (10) and the outer skirt is in a first, rest position thereby preventing the cap from being unscrewed. Outer skirt (5) can be moved to a second, stressed position in which lugs (7,8) disengage from slots (16,17) to allow partial unscrewing until lugs (7,8) are aligned with the opposite slot (17,16). The resilient component of the outer skirt (5) urges it back to the first, rest position and lugs (7,8) pass through slots (16,17) due to axial movement of inner skirt (3) during the partial unscrewing. Thereafter cap (1) can be fully unscrewed from the container.</p> |
