Abstract
A one-piece integrally molded container includes a finish having a deck and a pair of outlet openings surrounded by associated annular walls. A peripheral ring extends upwardly from the deck, and has a radial lip that helps retain the container in the mold tooling during the forming operation. The finish has a radial bead over which a bead on the inside diameter of a closure skirt snaps to secure the closure to the container. Annular walls on the closure surrounding the closure dispensing openings are received in plug sealing engagement within the annular walls surrounding the outlet openings on the container finish deck.
