ABSTRACT:
A container and closure combination, in which the container has a neck with a membrane-closed passage through the neck and the closure is adapted (e.g. screw-threaded) for engagement on the neck and has a projecting stud for separating the membrane from the neck and removing it. The membrane has holding means defining a cavity to receive and engage the outside of the projecting stud and a weakened region surrounding the holding means so that on application of the closure to the container the projecting stud can engage in the cavity and can then press on the membrane to break it at the weakened region leaving the membrane attached to the closure.
