ABSTRACT:
A one-piece dispensing closure has a laterally oriented dispensing opening therein, communicating with a longitudinal bore. A cap is integrally joined to the closure by a "living" hinge at one side of the cap and closure, and a male plug depends from the underside of the cap in a position to close the longitudinal bore and dispensing opening. The plug has spaced sealing areas thereon which cooperate with spaced sealing areas in the bore, and the cap has a detent on a marginal portion opposite the hinge to retain the cap in a closed position and to also retain the cap in an open position. The detent also effects a seal in the dispensing opening when the cap is in a closed position. Further detents on the cap and closure cooperate to limit opening movement of the cap relative to the closure. Thus, when the cap is closed, primary and secondary seals are provided in both the bore and dispensing opening, and when the cap is open, a seal is maintained in the bore. Further, the cap is detained in predetermined opened and closed positions.
