Abstract
A dispensing closure including a compression molded plastic closure having a base wall and a peripheral skirt having threads for engaging a container. An opening is formed in the base wall and a compression molded liner is molded in situ in the closure and includes a radial liner forming portion on the inner surface of the base wall of the closure. An integral nozzle is compression molded with the liner and extends axially through the opening in the base wall. One or more slits in the nozzle define a dispensing opening through which the contents of the container can be dispensed by squeezing the container. In another form, the dispensing closure is provided with a liner such that a syringe needle is used to penetrate an elastomeric wall for removal of the liquid contents of the package.
