DETAILED DESCRIPTION

Turning to FIG. 1, a closure 10 is shown according to an exemplary embodiment. Closure 10 includes an end wall or top portion, shown as a top panel 12. Top panel 12 is generally circular in shape and is generally planar (i.e., the outer surface of top panel 12 is flat and positioned substantially in a single plane) and is centered around rotational axis 8. Closure 10 includes a sidewall, shown as skirt 20, that extends downwardly from a bottom surface 16 at a periphery of top panel 12. Upper surface 14 of top panel 12 faces upwards and away from bottom surface 16.

Skirt 20 is generally annular in cross-section and is substantially perpendicular to the plane defined by top panel 12. As shown in FIG. 1, closure 10 may also optionally include a plurality of raised ribs extending radially outward from an outer surface of skirt 20. As shown in FIG. 1, the ribs may extend vertically along at least a portion of the vertical length of the outer surface of skirt 20 to provide a textured or gripping surface that may facilitate opening of closure 10.

Located along the inner surface of the skirt 20 is a container engagement structure, shown as threading 26, configured to interact with a corresponding closure engagement structure located on the neck 102 of the container 100 to which closure 10 is to be sealingly applied. Threading 26 extends inwardly from the inner surface of skirt 20. Threading 26 is configured to engage corresponding threading present on the container 100 to which closure 10 is attached. In various other embodiments, closure 10 may include any other number of types of engagement structures, such as but not limited to snap beads, lugs, etc.

In some embodiments, closure 10 may further include a tamper evidencing structure, such as frangible connections 38, configured to provide visual indication to a user that the initial sealing engagement between closure 10 and the container 100 has been disrupted as a result of the closure 10 being partially or entirely opened. In one embodiment the frangible connections 38 couple body 32 of closure 10 to retention band 30. Upon application of twisting force to closure 10 to remove closure 10 from a container 100, a majority if not all frangible connections 38 are configured to break, separating body 32 from retention band 30 except for an intervening connection, such as first tether 56 and second tether 57.

In a specific embodiment, closure 10 includes an interfacing structure, shown as J-Band 42, that engages cooperating structures on the neck of the container to prevent closure 10 from being removed from the container without a majority and/or all of frangible connections 38 breaking.

Closure 10 includes two lines of weakness, shown as a first line of weakness 44 and a second line of weakness 46, that extend circumferentially around closure 10. In one embodiment, both first line of weakness 44 and second line of weakness 46 include frangible connections 38 that break when closure 10 is opened. In another embodiment, first line of weakness 44 includes frangible connections 38 that break when closure 10 is opened, and second line of weakness 46 does not include frangible connections.

First line of weakness 44 extends circumferentially from a first end 48 to a second end 50. First end 48 and second end 50 are separated by circumferential distance 60, with respect to axis 8. In a specific embodiment, distance 60 is between 10 degrees and 45 degrees, and more specifically is between 15 degrees and 35 degrees.

A hinge 54 is located between first end 48 and second end 50. Skirt 20 cylindrical wall pivots with respect to retention band 30 around the hinge 54. First line of weakness 44 separates skirt 20 from retention band 30. A plurality of frangible connections 38 extend across first line of weakness 44 to couple body 32 of closure 10 to retention band 30. Second line of weakness 46 is closer to top panel 12 than first line of weakness. Second line of weakness 46 extends circumferential distance 62 around closure with respect to axis 8. In a specific embodiment, distance 62 is between 60 degrees and 150 degrees, and more specifically is between 90 degrees and 120 degrees.

When the container 100 that closure 10 is coupled to is oriented in a typical upright position, top panel 12 is substantially horizontal to a ground surface and skirt 20 is generally vertical with respect to the ground. First line of weakness 44 circumferentially surrounds closure 10 at a substantially consistent distance from top panel 12. Second line of weakness 46 partially circumferentially surrounds closure 10 a substantially consistent second distance from top panel 12 that is less than the distance of the upper line of weakness 44. In this arrangement, first line of weakness 44 and second line of weakness 46 are substantially parallel to each other. In various embodiments, frangible connections 38 are disposed periodically throughout one or more of first and second lines of weakness 44, 46, such as approximately every 20 degrees of arc from the perspective of center axis 8 of closure 10.

First and second tethers 56, 57 are sturdier than frangible connections 38 and therefore less likely to break when closure 10 is being opened. As a result, often first and second tethers 56, 57 remain unbroken and therefore body 32 of closure 10, which includes top panel 12 and skirt 20, remains coupled to retention band 30 via first and second tethers 56, 57. One or more of tethers 56, 57 (e.g., one or more of first tether 56 and second tether 57) extend in opposing directions away from hinge 54 towards body 32 of closure 10.

When closure 10 is opened with respect to container 100, body 32 pivots with respect to the container neck around hinge 54, the inlet of the container 100 is uncovered, and the contents of the container 100 (e.g., water) may be consumed, removed, etc.

Subsequent to a user removing the contents of the container 100, body 32 of closure 10 may be re-coupled to the inlet of the container 100. Skirt 20 is positioned above container inlet 102 and rotated to engage threading 26 with the outer surface of the container inlet 102 (e.g., by rotating sidewall clockwise from a perspective above top panel 12).

FIGS. 4-5 depict various aspects of closure 210. Closure 210 is similar to closure 10 except as described herein. Closure includes first line of weakness 244 and second line of weakness 246. The lines of weakness in closure 210 are similar to the lines of weakness in closure 10, except that their respective arrangement is reversed so that first line of weakness 244 is above second line of weakness 246 in closure 210. Skirt 220 and body 232 are separated from retention band 230 by first line of weakness 244.

FIGS. 6-7 depict various aspects of closure 310. Closure 310 is similar to closure 10 except as described herein. Body 332 and skirt 320 are separated from retention band 330 by first line of weakness 344. Second line of weakness 346 extends diagonally from first line of weakness 344 before extending circumferentially around closure 310 beneath first line of weakness 344. Tether 356 is formed between first line of weakness 344 and second line of weakness 346. Skirt 320 and body 332 are separated from retention band 330 by first line of weakness 344.

FIGS. 8-9 depict various aspects of closure 410. Closure 410 is similar to closure 10 except as described herein. First line of weakness 444 extends helically around closure 410 such that a tether 456 is formed between first line of weakness 444 (best shown FIG. 8). First line of weakness 444 separates body 432 and skirt 420 from retention band 430. In a specific embodiment first line of weakness 444 extends between 405 and 495 degrees around closure 410 with respect to the rotational axis of closure 410, and more specifically first line of weakness 444 extends 450 degrees around closure 410.

FIGS. 10-11 depict various aspects of closure 510. Closure 510 is similar to closure 10 and especially closure 410 except as described herein. First line of weakness 544 extends helically around closure 510 such that a tether 556 is formed between first line of weakness 544 (best shown FIG. 10). First line of weakness 544 separates body 532 and skirt 520 from retention band 530. In a specific embodiment first line of weakness 544 extends between 380 and 420 degrees around closure 510 with respect to the rotational axis of closure 510, and more specifically first line of weakness 444 extends 400 degrees around closure 510.

Turning to FIGS. 12-15, various aspects of closure 610 and retaining band 614 are shown. Closure 610 is similar to closure 10 and the other closures except as described herein. Similarly, retaining band 614 in closure 610 is similar to retaining band 30 in closure 10 except as described herein. It is contemplated herein that retaining band 614 may be incorporated with any of the closures described herein.

Interference band 630 extends from retaining band 614 towards top panel 612 and includes a tapered formation that facilitates the body of the closure pivoting away from interference band 630, particularly when the closure includes a tethered formation that couples the body of the closure to the retaining band. Interference band 630 extends inwards from base 634 of retention band 614. Interference band 630 includes one or more apertures 632.

Interference band 630 extends a varying distance from base 634 at different circumferential positions with respect to axis 8. At the one or more locations below hinge 654 (see FIG. 14), interference band 630 has length 638. At the one or more locations opposite hinge 654 with respect to rotational axis 8 (see FIG. 15), interference band 630 has length 642, which is longer than length 638. In a specific embodiment, base 634 defines distance 644 between top of retaining band 614 at the weakened section, shown as line of weakness 634, and base 634 of retention band 614. In a specific embodiment, length 638 is less than 75% of length 642, and more specifically less than 60% of length 642, and even more specifically length 138 is less than 50% of distance 644.
