DETAILED DESCRIPTION

Referring first to FIGS. 1-12, in an embodiment, a closure 10, for closing a container 180 is shown. The closure 10 includes a top panel, shown as top wall 12, and a cylindrical wall, shown as skirt 20, perpendicular to the top wall 12. The skirt 20 extends downwardly from a bottom surface 16 of an outer periphery 18 of top wall 12 to a bottom edge 28 of skirt 20, shown as lower edge 28. An upper surface 14 of top wall 12 faces away from bottom surface 16 of top panel 12. The top wall 12 and skirt 20 are centered around rotational axis 8.

An upper weakened section, shown as a upper slit 30, includes one or more frangible connections 38 that extend across upper slit 30 to couple body 48 to retaining band 100. When closure 10 is initially opened, frangible connections 38 break providing a visual indication that closure 10 has been opened. Body 48 of closure 10 is above upper slit 30 and a retention band, shown as retaining band 100, is below upper slit 30. Upper slit 30 extends circumferentially around closure 10 from first end 32 to second end 34. Angle 36 is defined as angular separation of first end 32 from second end 34 with respect to rotational axis 8 of closure 10.

As is described in more detail below, tab 42 extends from body 48 of closure 10 towards retaining band 100. Connecting portions, shown as left tether 47 and right tether 49, maintain a coupling between body 48 and retaining band 100 even when closure 10 is opened.

Left tether 47 is separated from tab 42 by second weakened portion, shown as aperture 50. Aperture 50 includes lower portion 52 that extends circumferentially around closure 10, left portion 54 that extends vertically from a first end of lower portion 52, and right portion 56 that extends vertically from an opposing second end of lower portion 52. Similarly, right tether 49 is separated from tab 42 by right portion 56 of aperture 50. Third aperture 50 is between retaining band 100 and body 48. Third aperture 50 defines tab 42.

First aperture 37 extends vertically between the retention band 100 and the skirt 20. First aperture 37 is connected with the first end 32 of the line of weakness 30 when the closure 10 is opened. Similarly second aperture 39 extends vertically between the retention band 100 and the skirt 20. The second aperture 39 is connected with the second end 34 of the line of weakness 30 when the closure 10 is opened. Tab 42 is located circumferentially between first aperture 37 and second aperture 39.

A first tether, shown as left tether 47, is located between the first aperture 37 and the third aperture 50. The left tether 47 maintains a coupling between the skirt 20 and the retention band 100 when the closure 10 is opened. A second tether, shown as right tether 49, is located between the second aperture 39 and the third aperture 50. The right tether 49 maintains a coupling between the skirt 20 and the retention band 100 when the closure 10 is opened.

As will be described in more detail below, when closure is opened for the first time, body 48 of closure pivots away from the container neck and the retaining band 100. Body 48 remains coupled to retaining band 100 via left tether 47 and right tether 49. Left tether 47 and right tether 49 each include a line of weakness, shown as diagonal lines of weakness 44, which are configured to facilitate left tether 47 and right tether 49 deforming as closure 10 is being opened.

As body 48 pivots away from the container neck, tab 42 pivots towards the container neck. Tab 42 is positionable and configured to interface against the container neck to bias body 48 (e.g., skirt 20) of closure 10 away from the container neck, thus allowing a user to drink from the container neck with reduced or no interference from body 48 of closure 10.

In various embodiments, aperture 50 does not include frangible members 38. In various other embodiments, aperture 50 includes frangible members 38. In various embodiments, one or more of the closures described herein, such as closure 460, are formed by injection molding, compression molding, cutting slits, and/or combinations thereof.

Turning to FIG. 6, the interaction between the J-band and the container neck will be described. The container 180 includes a neck portion 182 defining an opening to the container 180. The neck portion 182 includes a mating sealing formation/neck thread 186 and a mating attachment formation/engagement ring 188. The skirt 20 includes an outer surface 24 and an opposing inner surface 22. The inner surface 22 includes a sealing/mating formation, shown as thread 26, to mate with the mating sealing formation/neck thread 186 of container 180. The closure 10 includes one or more sealing formations, shown as rings 17, that interface with neck portion 182 of container 180 to provide a fluid seal between closure 10 and container 180.

A retaining tamper-evidencing band, shown as band 100, includes at least one radially inwardly projecting retaining element, such as a J-band 122. J-band 122 is attached at a lower end to the inner surface of the tamper band via a J-band hinge. An upper, free end of the J-band is defined by an engagement surface. The retaining elements include a plurality of structures (e.g. beads, tabs, flanges) projecting radially inwards from the inner surface of band 100 and engage a corresponding retaining structure, such as annular projection 188 that extends from neck portion 182 of container 180.

When the closure 10 is applied to the neck portion 182 of the container 180, the sealing formation/mating thread 186 of container 180 engages the mating sealing formation/neck thread 26 of closure 10. One or more of rings 17 engage the mating attachment formation of container neck 180 to seal the container 180. When the closure 10 is removed from the neck portion 182, most or all of the frangible members 38 are broken, and the retaining band 100 remains engaged with the container neck 180. The body 48 of closure 10 remains attached to the retaining band 100 via left tether 47 and right tether 49. The tab 42 interacts with the mating attachment formation to maintain an open cap position wherein the body 48 of closure 10 is retained displaced from the opening of the container 180. In a specific embodiment, when body 48 of closure 10 is removed from neck portion 182, at least one of frangible members 38 break while at least one of frangible members 38 remain unbroken.

The tab 42 interacts with the mating attachment formation/engagement ring of the container neck to maintain an open cap position wherein the body 48 of closure 10 is retained displaced from the opening of the neck portion 182 of container 180. The left tether 47 and right tether 49 bias the tab 42 inward towards the neck portion 182 of the container 180, working together with the tab 42 to keep the body 48 in the open cap position on an angle θ (e.g., from 90° to 135°). In a specific embodiment, the tab 42 contacts the neck thread 26 while the body 48 is in the open cap position.

It is contemplated herein that slit 30 in closure 10 may be formed such as, for exemplary purposes only and without limitation, via being slit open by a cutting device from a fully formed closure, being molded into the final form, being injection molded into the final form, and/or being molded to include one or more of the slits and a blade being used to cut the remaining one or more slits.

Turning to FIGS. 5-12, the opening of closure 10 relative to neck portion 182 of container 180 is depicted. Starting at FIGS. 5-6, closure 10 is depicted at the moment that most and/or all of frangible connections 38 have broken. Sealing rings 17 of body 48 are still sealed with neck portion 182. FIG. 6 depicts a cross-section of the portion of closure 10 and container 180 identified in FIG. 5. Left tether 47 and right tether 49 are shown in dotted line in FIG. 6, because they are not located along the cross-section line identified in FIG. 5. Instead, left tether 47 and right tether 49 are located to either side of the cross-section line identified in FIG. 5.

Turning to FIGS. 7-8, body 48 of closure 10 is starting to pivot away from neck portion 182 of container 180. Body 48 remains coupled to retaining ring 100 via left tether 47 and right tether 49. Similar to FIGS. 5-6, left tether 47 and right tether 49 retain the coupling between body 48 and retaining band 100 and are shown in dotted line in FIG. 8 because they are not located along the cross-section line identified in FIG. 7. Tab 42 is starting to pivot towards container 180 but not yet interfacing with neck portion 182 of container 180.
