DETAILED DESCRIPTION

Referring generally to the figures, various aspects of a closure, shown as a dispensing cap are shown. Closures and specifically dispensing closures or caps are used to enclose containers and can be coupled to the neck of containers (e.g., bottles) to aid in the dispensing of the stored liquid (e.g., water, milk, creamer). Applicant believes the closure discussed herein includes an improved structure allowing for easier alignment of the closure components and a more secure coupling between the closure components. The dispensing closure includes a pair of hinge pin receivers each with a pair of pin guides shaped to direct the opposing par of hinge assemblies of the pivoting closure cap into a pair of pin sockets in the closure base. The hinge pin receivers further include a receiver top to act as a ramp and detent groove above the pin receiver aiding in alignment and stability during pivoting. In contrast to the closure discussed herein, other dispensing closures frequently use an indentation in the base to receive the pin. Further, previous closures have problems with alignment because of shrinking and distortion associated with molding that are avoided by using the hinge pin receiver discussed herein.

Referring to FIGS. 1-4, a closure, such as a dispensing cap 10, is shown according to an exemplary embodiment. In general, dispensing cap 10 includes a pivoting closure cap 12 and a closure base 14. Closure base 14 includes a wall 15 extending from a lower or bottom edge 23 to an upper or top edge 25. Wall 15 and closure base 14 have a generally inward taper from lower edge 23 to upper edge 25. Closure base 14 further includes a generally vertical inner surface 39 (i.e., parallel to longitudinal axis 21 by plus or minus 10°) and a generally horizontal (i.e., generally perpendicular to inner surface 39 by plus or minus 10°), upward facing surface 40. A pair of hinge pin receivers 26a, 26b are positioned along generally vertical inner surface 39.

Pivoting closure cap 12 includes an upper surface 18 and a lower surface 49. Lower surface 49 faces closure base 14 and upper surface 18 is outward facing. Pivoting closure cap 12 further includes a first hinge assembly 22a and a second hinge assembly 22b extending downward from the pivoting closure cap 12. First and second hinge assembly 22a, 22b each include a support member 24 including a top end 27 connected to the cap and extending to a bottom end 29, a truncated hinge pin 70 extending generally perpendicular to and from the lower end of the support member to a distal end and a detent rib 66 extending upwardly from the truncated hinge pin 70 toward the top end 27 of support member 24.

Upper surface 18 includes a push pad 20. As will be discussed in greater detail below, when push pad 20 is pressed, hinge assemblies 22a and 22b and pivoting closure cap 12 are configured to pivot. Pivoting closure cap 12 pivots from a closed position to an open position when a force is applied to push pad 20. The force has a magnitude to move the detent rib 66 from within the detent groove 54. As the closure cap 12 pivots, the closure cap 12 simultaneously lifts and opens the dispensing cap 10 for use, so a liquid can be poured.

Referring to FIG. 2A an exploded perspective view of the closure of FIG. 1 is shown, with FIG. 2B showing an exploded perspective view of the closure rotated 180° clockwise from FIG. 2A. Closure cap 12 further includes a lip or protrusion 17 extending outward from closure cap 12 and configured to engage with closure base 14 when dispensing cap 10 is pivoted into a fully open position. Lip 17 engages with a corresponding protrusion 35 (see e.g., FIG. 3A) extending upward from wall 15 of closure base 14.

Referring to FIGS. 3A-3B, closure base 14 includes an anti-pry feature shown as a barrier wall 16. Barrier wall 16 is positioned in a recess 36 between wall 15 and the hinge pin receivers 26a, 26b adjacent to the rear of closure base 14. When push pad 20 is pressed, and pivoting closure cap 12 is pivoted to a maximum angle, lip 17 is positioned within recess 36 and engaged with protrusion 35. The engagement between lip 17 and protrusion 35 holds closure cap 12 in the fully open position and creates resistance to closure cap 12 pivoting from the open position to the closed position.

Closure base 14 includes a fluid channel 28 centered on a longitudinal axis 21 and includes an inner surface 34. Fluid channel 28 is a part of the dispensing system 30. Dispensing system 30 includes a lip or pour spout 32. Pour spout 32 is formed in the closure base 14 and positioned at least partially around and extending upward and away from fluid channel 28 at an angle. When connected to a container (e.g., a bottle), a user can pour a liquid (e.g., water, milk, creamer) out through fluid channel 28 and over pour spout 32 into a different container or cup when dispensing cap 10 is pivoted and lifted into an open position.

Barrier wall 16 is positioned between fluid channel 28 and hinge pin receivers 26a, 26b and helps to prevent pivoting closure cap 12 and closure base 14 from being physically pried apart when in a coupled or assembled position. Closure base 14 includes an upward facing surface 38 of wall 15. In some locations, upward facing surface 38 is perpendicular to generally vertical inner surface 39. In other areas, upward facing surface 38 may instead be partially curved as it angles downward toward the rear of closure base 14 where barrier wall 16 is located.

Referring to FIGS. 4A-4B, a top and a bottom view of a pivoting closure cap 12 is shown. Pivoting closure cap 12 further includes a cylindrical cap plug 44 extending toward closure base 14 from lower surface 49. Cylindrical cap plug 44 defines an opening 42 and is centered on longitudinal axis 21 and includes an exterior or outer surface 46. At a bottom, front portion of cylindrical cap plus 44 a projection 48 is configured to guide cylindrical cap plug 44 as it is received within fluid channel 28 of closure base 14 such that outer surface 46 engages with inner surface 34 of the fluid channel 28. The lift experienced by closure cap 12 during pivoting lifts or pulls the cylindrical cap plug 44 out of the fluid channel 28 such that when the closure cap 12 is in the open position, cylindrical cap plug 44 no longer blocks the flow of fluid out of dispensing cap 10.

Pivoting closure cap 12 further includes a pair of rear segments 50 of hinge assemblies 22a, 22b having a generally triangular shape and extending from a point adjacent to truncated hinge pin 70 to a base at lower surface 49. Rear segment 50 provides further support for support members 24 of hinge assemblies 22a and 22b.

Referring to FIGS. 5A-5B, side cross-sectional views of pivoting closure cap 12 taken along line 5a-5a and line 5b-5b are shown. Hinge assemblies 22a, 22b each include an anti-removal component, shown as tab 71. Tab 71 extends from the distal end of truncated hinge pin 70 toward the top end 27 of the support member 24. The tab 71 engages the respective hinge pin socket 37 to retain the hinge pin 70 within the socket 37 while the pivoting closure cap 12 simultaneously pivots and is lifted. Truncated hinge pin 70 includes an angled surface or pin bevel guide 72 at the bottom end of hinge pin 70. In some embodiments, truncated hinge pin 70 further includes an opposing pair of angled side surfaces 74 to further improve engagement with hinge pin receiver 26a, 26b during alignment and assembly of dispensing cap 10.

Each pin bevel guide 72 engages with a receiver top 52 to direct a hinge assembly 22a or 22b into a respective hinge pin socket 37. Receiver top 52 is positioned above hinge pin socket 37. Detent rib 66 has a beveled outer surface 68 configured to engage with detent groove 54 during alignment of hinge assembly 22 as pivoting closure cap 12 couples to closure base 14. In some embodiments, detent rib 66 includes beveled edges along the sides of detent rib 66 and extending in the longitudinal direction of detent rib 66. Detent rib 66 engages with detent groove 54 to direct each hinge assembly 22a, 22b into a respective hinge pin socket 37 during alignment and assembly of dispensing cap 10. When dispensing cap 10 is in a closed position, detent ribs 66 rest within detent grooves 54. When dispensing cap 10 is pivoted into an open position, detent ribs 66 pivot out of detent grooves 54 such that when dispensing cap is in an open position, detent ribs 66 rest outside detent grooves 54.

Referring to FIGS. 6-7 details of closure base 14 and hinge pin receiver 26a are shown. Hinge pin receiver 26b is positioned on the opposing side of closure base 14 from hinge pin receiver 26a. Hinge pin receiver 26a receives hinge assembly 22a and hinge pin receiver 26b receives hinge assembly 22b. Dispensing cap 10, and specifically closure base 14 includes the elongated hinge pin sockets 37 defined within and extending through the inner surface 39 of wall 15 on opposing sides of closure base 14. Each hinge pin socket 37 extends through inner surface 39 of wall 15 and provides increased resistance to removal for hinge assemblies 22a, 22b within hinge pin socket 37 because it is harder to remove hinge assemblies 22a, 22b from hinge pin socket 37 when compared to the indentation used in many other closures. In some embodiments, hinge pin socket 37 is produced using a slide during injection molding.

Hinge pin receiver 26a includes a receiver top 52 and a receiver bottom. Hinge pin receiver 26 includes an elongated hinge pin socket 37 formed in the receiver proximate the receiver bottom and further includes the detent groove 54 extending from the pin socket 37 toward the receiver top. The hinge pin 70 is located and rotatable within the hinge pin socket 37.

The components of the hinge pin receivers 26a, 26b discussed herein, allow for improved accuracy during coupling or assembly of dispensing cap 10 and specifically hinge assemblies 22a, 22b and hinge pin sockets 37. Without the guidance, many closures have problems reliably placing the pin for coupling during assembly. The problems can be related to shrinkage and distortion that are avoided by the design discussed herein.

Hinge pin receiver 26 further includes a pair of tapered pin guides or ears 56. A first tapered pin guide 56 extends from the receiver bottom toward the receiver top along one side of the pin socket. A second tapered pin guide 56 extends from the receiver bottom toward the receiver top along the other side of the pin socket 37 to facilitate engagement of the hinge pins 70 with the hinge pin sockets 37.

In some embodiments, pin guides 56 include a beveled outer edge 55. The pin guides define an angle between the portions of outer edge 55. In other embodiments, the outer edge of pin guides 56 may only be beveled on one side or not beveled at all.

Receiver top 52 acts as guide ramp and is positioned above hinge pin socket 37 and angled such that the inner surface 39 of wall 15 is connected to upward facing surface 38 of wall 15. Detent groove 54 includes an inner groove surface 62 shaped and configured to receive detent rib 66 and maintain the position of hinge assemblies 22a, 22b when dispensing cap 10 is in the closed position. In some embodiments, detent groove 54 includes beveled edges along the sides of detent groove 54 extending in the longitudinal direction of detent groove 54.

Hinge pin receiver 26 further includes a projection, shown as cam surface 60 located on horizontal, upward facing surface 40 that defines the receiver bottom. Cam surface 60 is positioned at the bottom of hinge pin receivers 26a, 26b along the receiver bottom. Cam surface 60 and pin guide 56 partially define an opening 58 connected to hinge pin socket 37 such that hinge pin socket 37 is not symmetrical. Opening 58 allows for some interference between cam surface 60 and pin guide 56 to resist the hinge assembly movement without providing so much resistance that dispensing cap 10 would be prevented from opening.

Referring to FIGS. 8-9 provide detailed views of hinge assembly 22b when dispensing cap 10 is in a closed position with hinge assembly 22b extending through hinge pin socket 37 as shown. As discussed previously, receiver top 52 and detent groove 54 help to align hinge assembly 22 and maintain the position of hinge assembly 22b through friction so the distal end including truncated hinge pin 70 can be received within hinge pin socket 37 and so that hinge assembly 22b maintains positioning within hinge pin socket 37 during pivoting.

Truncated hinge pin 70 extends within hinge pin socket 37 beyond a stepped portion 78 of wall 15 and past the internal surface 76 of wall 15. The positioning of truncated hinge pin 70 helps to resist removal of hinge assembly 22 from the coupled or locked position. As shown in FIG. 9, anti-removal tab 71 is positioned to engage with stepped portion 78 of wall 15 to resist removal of hinge assembly 22a from hinge pin socket 37. As hinge assembly 22a pivots and lifts, tab 71 continues to interfere with stepped portion 78 and internal surface 76.

As mentioned above, when push pad 20 is pressed, hinge assemblies 22a, 22b are configured to pivot. When a user presses push pad 20 with enough force to overcome the interference between the hinge assemblies 22a, 22b and the hinge pin receivers 26a, 26b, the detent rib 66 pivots out of detent groove 54, opening dispensing cap 10 for use. Hinge assemblies 22a, 22b and pivoting closure cap 12 pivot to an angle between 30° and 40° and more specifically about 35° (e.g., 35° plus or minus 2°).

Referring to FIG. 12, a detailed view of the internal structures of wall 15 are shown. As previously discussed, truncated hinge pin 70 and anti-removal tab 71 extend beyond the stepped portion 78 and internal surface 76 of wall 15 when pivoting closure cap 12 is coupled to closure base 14 to resist removal of hinge assembly 22b from hinge pin socket 37.
