Abstract
A one-piece integral plastic container is disclosed which has an outer closure or overcap removable along a frangible line of weakness, and a separately-formed inner closure that is maintained in sterile condition by the outer closure until the container contents are dispensed. The inner closure comprises a tubular member inserted in fluid-tight relationship within the container neck after the container body and neck are molded, but prior to formation of the outer closure. The tubular member thus provides the dispensing outlet for the container and is maintained in sterile condition by the overcap which encloses it.
