ABSTRACT:
A process for producing a container and closure assembly includes molding a preliminary container including a closed bottom portion, a body portion and a shoulder and neck portion. The shoulder and neck portion is separated from the body portion. An open ended second container is formed from the body portion, the second container having a rim at its open end and an encircling wall. The open end of the second container is then closed with a closure comprised of a cap and a cap liner. The cap liner has a weakened portion adapted to be broken by the cap. The cap or the cap liner are formed from the shoulder and neck portion of the preliminary container.
