A dispensing closure, including a horizontal deck, an aperture through the deck, arid a collar depending below the aperture in the deck, is snapped over an annular bead on the neck of a molded plastic bottle. A stop wall, comprising a pair of ribs mounted for pivotal movement, is formed in the interior of the body of the closure; a gap is centrally located between the ribs. A radially projecting lug, which is triangular when viewed in side elevation, is formed on the sloping collar of the container; a dovetailed segment is defined at the free end of the lug. The collar on the closure has interrupted beads, so that the dispensing closure is secured to the container by snapping the interrupted beads over the annular bead on the neck of the container. The ribs of the stop wall flex pivotally outwardly when contacting the outer end of the lug. The dispensing closure is rotated relative to the container, in either the clockwise or counterclockwise direction, so that the dovetailed segment of the lug projects into the central aperture in the stop wall; the free ends of the ribs engage the dovetailed segment and lock the closure into proper alignment with the container.
