  • Method and apparatus for installing an insert to seal a container
    Patent number: 5351462
    Abstract: A method and apparatus are provided for molding a parison of thermoplastic material to form a container with an inwardly extending flange around the container closure. The container body portion is filled with product through an access opening. An insert article serving as the container closure is then positioned within the access opening. The parison is radially compressed inwardly against the insert article to form a bead of thermoplastic material contiguous with the insert article. The bead is then permanently deformed against the insert article axially in the direction of the container body portion. This forms a flange over a portion of the article to retain the insert article on the container while sealing the container.
