Abstract
The present invention provides a child-resistant closure for a container. The closure comprises a dispensing nozzle, a cap for the dispensing nozzle, inter-engaging formations and a resiliently deformable element. The inter-engaging formations provided on the closure hold the cap to the nozzle in an interengaged assembly thereof. The resiliently deformable element biases the cap and the nozzle apart. The inter-engaging formations comprise a retaining slot for receiving a retainer and a retainer for engagement with the retaining slot. The retaining slot, retainer and resiliently deformable element are arranged so that the cap and the nozzle are retained interengaged in the interengaged assembly by bias from the resiliently deformable element. The release of the interengaging formations is achieved by applying sufficient pressure axially to the assembly to overcome the bias of the resiliently deformable element, and sufficient turning force to move the retainer out through the opening of the retaining slot.
