Abstract
A dispensing closure 10, including a horizontal deck (fig 1,18) an aperture 20 through the deck, and a collar 22 depending below the aperture in the deck, is snapped over an annular bead 58 on the neck 56 of a molded plastic bottle 50. A stop wall 42,44, comprising a pair of ribs 42,44 mounted for pivotal movement, is formed in the interior of the body of the closure; a gap (fig 2,40) is centrally located between the ribs. A radially projecting lug 60, which is triangular when viewed in side elevation, is formed on the sloping collar 22 of the container; a dovetailed segment is defined at the free end of the lug. The collar on the closure has interrupted beads (fig 6,26), so that the dispensing closure is secured to the container by snapping the interrupted beads (26) over the annular bead 58 on the neck of the container. The ribs of the stop wall 42,44, flex pivotally outwardly when contacting the outer end of the lug 60. 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.

240656 1
DISPENSING CLOSURE WITH STOP WALL FOR
POSITIVE ALIGNMENT ON CONTAINER
Field of the Invention:
1] The invention pertains to dispensing closures, employing stop walls, that cooperate with a lug defined on the neck of a plastic container to establish positive alignment of the dispensing closure relative to the container.
BACKGRO=D OF THE INTION [0002] Dispensing closures, including lugs, stops, and the like, for positively aligning the closure relative to a specific location, on a plastic container, such as the front of a bottle, are known. To illustrate, U.S. Patent 5,143,234, granted September 1, 1992 to Richard Lohrman et al, discloses a dispensing closure (20), employing a living, or snap-acting, hinge (26), and utilizing an alignment rib (30) for providing a positive alignment of the thumb recess (14) for facilitating the lifting of a hinged closure lid (24). In the preferred embodiment of Figures 1-5, cooperating alignment ribs (30, 48) are located upon the bottle neck and the interior of the closure.
The alignment rids are interrelated in such a manner that when the closure is threaded up the bottle neck, the mating ribs do not contact one another in the first instance, but eventually contact and abut each other after at least one full turn of the closure upon the bottle neck, and before one and one-half full turns of the closure upon the bottle neck, thereby positioning the thumb recess (14) in the center of the bottle face, as shown in Figure 4. The bottle face contains the brand name of the product, an advertisement for such product, fanciful graphics, etc. so that the proper alignment of the dispensing closure is of commercial significance.
3] Another positive orientation system for a dispensing closure, with an internally threaded skirt, and a closure, IS shown in U.S. Patent 5, 145,080, granted September 8, 1992, to Leo R. Imbery, Jr. The Imbery, Jr. patent discloses a container l ee ce (30) havl,-g a neck (36) defining an opening (38) to the interior of the container, an external screw thread (SO), and a protuberance (80). The protuberance has generally opposite abutment surfaces (leading surface 96, and trailing surface 98), and at least one cam surface (106, 110) extending between the abutment surfaces. The closure (32) has a skirt (44) defining an internal screw thread (98) for engaging the external screw thread on the container. The skirt defines a recess (82) for receiving a protuberance (80). The recess is defined at opposite ends by spaced-apart engaging surfaces (121, 122) for confronting the abutment surfaces of the protuberance. The skirt is sufficiently resilient, as shown in Figure 6, to deform as relative threading engagement is effected between the closure and the container neck to accommodate relative movement of the container neck and closure until the protuberance IS received in the recess, as shown in Figure S. to prevent relative rotation between the closure and the container.
[OOO4] Another positive orientation system for dispensing closures secured to plastic containers is disclosed in U.S. Patent 6,431,381, granted August 13, 2002, to Jeffrey T. Randall.
In the preferred embodiment of Figures 1-5, Randall discloses a closure (30) having a lug seal (50) that cooperates with a container neck lug (28) formed on a shoulder (27) on an interior surface (25) of the container neck (26). In the alternative embodiment of Figures 6-11, Randall discloses a positive orientation system employing at least one neck lug (128) on an end of the container neck (121), and the closure body (132) is provided with at least the closure neck lug (154) extending from the closure neck, and adapted to engage a corresponding one of the at least one (usually two) neck lugs. The engagement of the lugs limits the threaded engagement between the closure and the container during Installation of the dispensing closure, but permits unthreading removal of the closure from the container, when necessary or desirable. ce.

SALARY OF THE INVENTION
5] It is an object of the invention to provide a versatile dispensing closure that is forced downwardly and snapped over a bead on the neck of the container, and is subsequently aligned to the neck of the container by a rotational movement. The dispensing closure relies upon interrupted beads, on the interior of a depending collar, to seat the closure.
6] It is another object of the invention to provide a dispensing closure with a stop wall situated in the interior of the closure for cooperation with a plastic container that is characterized by a radially extending lug, or stop. The dispensing closure is snapped into engagement with the neck of the container, and is then rotated until the deformable stop wall engages the lug, and captures same, to positively align for the cap relative to the body of the container.
[OOD7] Furthermore, it is an object of the Invention to provide a unitary, molded plastic dispensing closure with a stop wall located in the interior of the dispensing closure between the skirt and the centrally located collar. A central opening or aperture divides the stop wall into two spaced ribs; each rib is flexible. The ribs deform, until the lug inserted in the central aperture, thereby defining the positively oriented, or aligned, position of the dispensing closure relative to the body of the container. One rib will flex if the closure is rotated to position in the clockwise direction, the other rib is flexed if the closure is rotated to aligned position in the counter clockwise direction.
[00081 Additionally, it is an object of The invention to provide a molded plastic dispensing closure with an internal stop wall that cooperates with a plastic container that utilizes a projecting lug located on the sloping collar of the container.
9] Lastly, it is an object of the invention to provide a unique method of securing the molded dispensing closure to the neck of the container in an aligned manner. The method, which is compatible with automated high speed assembly machines, includes the steps of (1) snapping an interrupted bead on the skirt of the dispensing closure over an annular bead on the neck Be ee of the container, (2) rotating the closure, (3) until the stop wall in t},e interior of the closure is seated upon tile remote end of a radially projecting lug on the container. The stop wall is defined by a pair of flexible, pivotal ribs, and an aperture is formed between the free edges of the ribs to receive the lugs.
The dispensing closure may be rotated in the clockwise, or counterclockwise, direction until the ribs engage the opposite sides of the radially projecting lug on the container and define the aligned position for the closure.
0] Yet other objects, and advantages, of the instant invention will become readily apparent to the skilled artisan, when the appended drawings are construed in harmony with the
specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
8] Figures 1 and 2 show an integrally molded dispensing closure 10 constructed in accordance with the principles of the instant invention. Dispensing closure 10 comprising a body 12, a lid 14, and a ''living'' hinge 16 for securing the lid to the body for pivotal movement relative thereto. Body 12 includes horizontally extending deck 18, with a centrally located aperture 20. An annular collar 22 depends below deck 18, and a plug seal 24 encircles aperture 20 and extends radially about the aperture.
Interrupted beads 26 are spaced around the inner face of collar 22.
9] A recess 30, which receives the thumb, or other finger, of the user of the dispensing closure, is located at the "front" of the closure, diametrically opposite living hinge 16. When lid 14 is pivoted to its closed position, plug or spud 32 is pressed into central aperture 20 to seal same. Then the lld is pivoted to its open position, it is retained in a position that does not impede the discharge of product through aperture 20. A camming lug 34 extends above hinge 16 and cooperates with cam surface 36 that extends above deck 18 on body 12, to stress hinge 16, within its resilient limits, to cause the lld to move, in a toggle-like manner, between its opened, and closed, positions.
0] Stop wall 38 is situated within the interior of body 12 of closure 10, between the exterior skirt and collar Z2, as shown in Figure 1. Stop wall 38 extends across the annular body of closure 10 in chord-like fashion, as shown in Flqure 2. A gap is located in the central area of stop wall 38, to divide the stop wall into resilient ribs 42 and 44, of equal size.
Reinforcing stays, 46, 48 may be used to rigidity the ribs 42, 44, and prevent excessive deformation.
1] Figures 3 and 4 depict a deformable plastic container to which, or upon which, dispensing closure 10 IS applied Contalner 50 comprises a body 52, which may be cylindrical, a sloping collar 54, and a vertically extending neck, or floish, 56 that encircles a discharge passage 57. An annular bead 58 encircles neck 56, and a radially projecting lug 60 extends outwardly below neck 56. tug 60 Is triangular In shape, when :. '': Be. Be. Beee.
viewed lo side elevation, in Figure 4. Triangular cut-outs are defined lo opposing sides of lug 60, so that the lug terminates, at its outer or remote end, in a dovetailed segment 62 [0021] Flqure 5 shoves collar 22 of dispensing closure 10 pressed downwardly so that interrupted beads 26 snap over annular bead 58 on neck 56 of container 50. The lower end of body 12 of closure 10 rests upon sloping collar 54. Rib 44 of stop wall 38 on dispensing closure 10 presses against the remote end 62 of lug 60, and pivots outwardly.
2] Figure 6 shows the position that the various structural components of the instant invention assume when a torque is applied to dispensing closure 10, after the closure has been seated upon container 50. . f0023] Figure 7 shows, in a schematic fashion, dispensing closure 10 snapped over bead 58 (not shown) on neck 56 of container 50. Stop wall 38 contacts dovetailed segment 62 of lug 60, and the lug forces rib 44 to flex outwardly. After closure is seated, conventional capping apparatus applies a rotational force or torque to closure 20 to rotate same typically in a clockwise direction, as lodicated by the directional arrow.
4] The clockwise rotation of closure 10 allows dovetailed segment 62 of lug 60 to become seated with gap 40 between ribs 42, 44 of stop wall 38. The cut-outs in the dovetailed shape of segment 62 receive, and seat, the free ends, or edges, of ribs 42, 44, to define the aligned position between dispensing closure and container 50. The seating action is sufficiently robust so that continued rotational torque imparted by the capping apparatus, is insufficiently robust so that continued rotational torque imparted by the capping apparatus, is insufficient to overcome same. The aligned position, in most instances, indicates that the recess 30 at the "front" of the closure is aligned with the front face of the container, which bears the brand name, product description, fanciful graphics, and other information relating to the product retained within the container.
ce Be e t e [0025] Figure 8 shoves dovetailed segment 62 on lug 60 retained in its 'theme" position By the engagement of the free ends of ribs 42, 44 with the cut-outs on opposite sides of dovetailed segment 62 on lug 60. The ''home" position determines the positive alignment of dispensing closure 10 with container 50 so that recess 30 is situated at the 'front" of the container, in alignment with the front label (not shown).
6] Modifications and revisions will readily occur to the skilled artisan; for example, the closure may be rotated counterclockwise, and segment 62 at the free end of lug 60 may assume a different shape. "Livings, hinge 16 may be replaced by a plastic strap, or straps. Consequently, the appended claims should not be limited to their literal terms, but should be broadly construed in a manner consistent with the breadth of the invention.
