ABSTRACT:
A package that is made of a blown plastic container and a two-piece or composite closure which is secured to a neck portion of the container. The closure includes a molded plastic plug style closure with an inner annular member which engages the inside of the neck of the container, an outer annular member which closely surrounds the outside of the neck of the container and a top panel from which the inner and outer annular members depend and which spans the rim of the container. The second piece of the closure is a molded plastic collar which surrounds the outer annular member of the plug style closure and which is frictionally interlocked therewith. The bottom of the collar has an inwardly and upwardly extending flange which engages a bead on the outside of the neck of the container to interlock the collar and the container. Further, the collar has one or more vertical tear strips to permit the tearing of the collar to thereby permit its removal from the container, and thereby to permit the removal of the plug style closure from the container, and this tearing of the collar imparts tamper indicating characteristics to the closure and to the package which includes such closure. The container has a radial shoulder positioned below the bottom of the collar to prevent the collar from being moved axially downwardly on the container.
