A dispensing closure, including a horizontal deck, an aperture through the deck, and 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.

What is claimed is: 1. In combination, a container and a dispensing closure secured to said container for discharging the contents thereof, a) said container comprising a container body, a sloping collar sloping inwardly and upwardly from said container body, and a neck extending above said sloping
What is claimed is: 1. In combination, a container and a dispensing closure secured to said container for discharging the contents thereof, a) said container comprising a container body, a sloping collar sloping inwardly and upwardly from said container body, and a neck extending above said sloping collar, b) a bead encircling said neck of said container, c) a lug formed on said sloping collar and extending radially outwardly and away from said neck, d) said dispensing closure comprising a closure body, a lid, and a hinge for securing said lid to said closure body for pivotal movement relative thereto, e) said dispensing closure further comprising a deck, an aperture through said deck, and an annular collar surrounding said aperture and depending below said deck, f) interrupted beads defined on the interior of said annular collar so that said annular collar may be snapped over said annular bead to seat the dispensing closure upon the container, g) a stop wall defined on a chord extending across the interior of the closure body of said dispensing closure, h) said stop wall including a pair of ribs separated by a central gap, one end of each rib being joined to the interior of said closure body of said dispensing closure to permit pivotal movement of each respective rib, and i) said stop wall cooperating with said lug to define a home position when said dispensing closure is rotated relative to said container after being seated thereon. 2. The combination of claim 1 wherein reinforcing stays are employed to strengthen said ribs comprising a pair of raised shoulders positioned on the respective ends of the ribs and adjacent to the central gap. 3. The combination of claim 1 wherein said lug is triangular when viewed in side elevation, the upper end of the lug extending parallel to, but spaced below, said annular bead on said container. 4. The combination of claim 1 wherein a segment is formed at the radially extending outer end of said lug by narrowing a portion of said lug to form the segment. 5. The combination of claim 4 wherein a triangular insert is removed from each of the opposite sides of said segment, thereby forming a dovetailed shape for said segment. 6. The combination of claim 5 wherein said dovetailed shape of said lug promotes locking of the closure in the home position, even when relatively high torques are applied to the dispensing closure. 7. The combination of claim 1 wherein a recess is formed in the closure body of said dispensing closure diametrically opposite said hinge, said recess enabling the user to lift said cap and pivot same away from said closure body. 8. In combination, a container and a dispensing closure secured to said container for discharging the contents thereof, a) the container comprising a container body, a sloping collar sloping inwardly and upwardly from the container body, and a neck extending above the sloping collar, b) a lug formed on the sloping collar and extending radially outwardly and away from the neck, c) the dispensing closure comprising a closure body having a deck an aperture through the deck, and an annular collar surrounding the aperture and depending below the deck, d) a stop wall defined on a chord extending across the interior of the closure body of said dispensing closure, the stop wall including a pair of ribs separated by a central gap, one end of each rib being joined to the interior of the closure body of the dispensing closure to permit pivotal movement of each respective rib, e) the stop wall cooperating with the lug to define a home position when the dispensing closure is rotated relative to the container after being seated thereon, and f) means for securing the dispensing closure to the container. 9. The combination of claim 8 wherein reinforcing stays are employed to strengthen said ribs comprising a pair of raised shoulders positioned on the respective ends of the ribs and adjacent to the central gap. 10. The combination of claim 8 wherein said lug is triangular when viewed in side elevation, the upper end of the lug extending parallel to, but spaced below, said annular bead on said container. 11. The combination of claim 8 wherein a segment portion is formed at the radially extending outer end of said lug by narrowing a portion of said lug to form the segment. 12. The combination of claim 11 wherein a triangular insert is removed from each of the opposite sides of said segment portion, thereby forming a dovetailed shape for said segment portion. 13. The combination of claim 12 wherein said dovetailed shape of said lug promotes locking of the closure in the home position, even when relatively high torques are applied to the dispensing closure. 14. The dispensing closure of claim 8 wherein the means for securing the dispensing closure to the container comprises interrupted beads defined on the interior of the annular collar which cooperate with an annular bead on the neck of the container. 15. A dispensing closure for a container, comprising: a closure body having a deck, an aperture through the deck, and an annular collar surrounding the aperture and depending below the deck; a stop wall defined on a chord extending across the interior of the closure body of the dispensing closure, the stop wall including a pair of ribs separated by a central gap, one end of each rib being joined to the interior of the closure body of the dispensing closure to permit pivotal movement of each respective rib; and means for securing the dispensing closure to the container. 16. The dispensing closure of claim 15 wherein reinforcing stays are employed to strengthen said ribs comprising a pair of raised shoulders positioned on the respective ends of the ribs and adjacent to the central gap. 17. The dispensing closure of claim 15 wherein the means for securing the dispensing closure to the container comprises interrupted beads defined on the interior of the annular collar which cooperate with an annular bead on the neck of the container.
