[0028] Referring generally to the figures, various embodiments of a closure are shown. Closures are generally used to enclose contents, such as within containers. For example, closures are used to enclose liquids inside liquid-containing containers, such as water bottles. The present application provides a closure with a tether and hinge formation that permits the body of the closure to remain coupled to the container even after the closure is opened.

[0029] In various embodiments, the closure(s) described herein provide a tether structure to couple the closure body to a retaining band, which remains coupled to the container. The closure also includes a tab formation that facilitates users drinking contents from the container. In particular, the tab biases the body of the closure away from the container neck when the closure is opened. Applicant has observed that providing weakened section extensions extending from the lower weakened portion (e.g., a lower slit) as described herein provides improved performance benefits for the closure. For example, the closure can be more easily removed from and reattached to the container neck by virtue of the extensions elevating the upper portion of the container compared to other closures without such extensions.

[0030] Referring to FIGS. 1-12, in an embodiment, various aspects of closure 110 are shown. Closure 110 includes a top panel 114 and a cylindrical wall 122 perpendicular to the top panel 114. Top panel 114 includes an upper surface 116 and an opposing lower surface 118. In various embodiments, closure 110 includes rotational axis 112 about which top panel 114 is centered. Cylindrical wall 122 extends downwardly from lower surface 118 of outer periphery 120 of top panel 114. Cylindrical wall 122 extends away from upper surface 116 of top panel 114. Cylindrical wall 122 includes an inner surface 124 and an opposing outer surface 126, the inner surface 124 facing towards rotational axis 112 and outer surface 126 facing away from rotational axis 112.

[0031] Threading 128 extends from inner surface 124 towards rotational axis 112. Threading 128 is configured to couple closure 110 to a container, such as container neck 192 of container 190.

[0032] Closure 110 includes retention band 150 pivotally coupled to the cylindrical wall 122, the retention band 150 attached to cylindrical wall 122 by a plurality of frangible members 138. The frangible members 138 provide a visual indication, when broken, that the closure 110 has been opened.

[0033] Closure 110 includes a first weakened section 130 that separates cylindrical wall 122 and retention band 150. First weakened section 130 includes one or more frangible members 138 that couple cylindrical wall 122 to retention band 150. Stated another way, frangible members 138 extend across first weakened section 130 to connect cylindrical wall 122 and retention band 150. When closure 110 is initially opened, frangible members 138 break, thus providing a visual indication that closure 110 has been opened.

[0034] First weakened section 130 separates cylindrical wall 122 from retention band 150. First weakened section 130 extends circumferentially around closure 110 from first end 132 to second end 134. First end 132 to second end 134 define angle 136. In various embodiments, the angle 136 is acute, and more specifically is between 10 and 80 degrees with respect to the rotational axis 112.

[0035] Closure 110 includes a second weakened section 160 that extends circumferentially with respect to rotational axis 112 and is distinct from first weakened section 130. Second weakened section 160 together with first weakened section 130 form various features in closure 110. As is described in more detail below, tab 142 extends from cylindrical wall 122 towards retention band 150. In various embodiments second weakened section 160 is above first weakened section 130, such as most of second weakened section 160 being above first weakened section 130, 90% of second weakened section 160 being above first weakened section 130, and / or all of second weakened section 160 being above first weakened section 130.

[0036] In various embodiments, first weakened section 130, second weakened section 160, and / or one or more of weakened section extensions 170 are formed by slitting the respective section with a knife after the closure is formed. In various embodiments, first weakened section 130, second weakened section 160, and / or one or more of weakened section extensions 170 are formed with one or more frangible members 138 that break when the closure 110 is opened. In various embodiments, first weakened section 130, second weakened section 160, and / or one or more of weakened section extensions 170 are formed when the closure 110 is initially formed, e.g., the first weakened section 130, second weakened section 160, and / or one or more of weakened section extensions 170 are integrally formed when closure 110 is initially formed.

[0037] In various embodiments, closure 110 includes tethers 154. Tethers 154 are defined between first weakened section 130 and second weakened section 160 and extend between cylindrical wall 122 and retention band 150.

[0038] Stated another way, closure 110 includes first tether 155A that couples the cylindrical wall 122 to the retention band 150 after the plurality of frangible members 138 are broken, and the first tether 155A extends between one of the lateral portions 166 (e.g., lateral portion 167A) and the first weakened section 130, and closure 110 includes a second tether 155B that couples the cylindrical wall 122 to the retention band 150 after the plurality of frangible members 138 are broken, and the second tether 155B extends between the other of the lateral portions 166 (e.g., lateral portion 167B) and the first weakened section 130.

[0039] As will be described in more detail below, when closure 110 is opened for the first time, cylindrical wall 122 pivots around hinge 140 away from the container neck 192 and the retention band 150. Cylindrical wall 122 remains coupled to retention band 150 via tethers 154 after frangible members 138 are broken. As cylindrical wall 122 pivots away from the container neck 192, tab 142 pivots towards the container neck 192. Tab 142 is positionable to interface against the container neck 192 and to bias cylindrical wall 122 of closure 110 away from the container neck 192, thus allowing a user to drink from the container neck with little to no interference from cylindrical wall 122 of closure 110.

[0040] Turning to FIGS. 2-3 in particular, in a specific embodiment second weakened section 160 is formed by a series of portions that extend circumferentially around closure 110 at varying distances from top panel 114. Second weakened section 160 includes a central portion 162 and lateral portions 166 that extend circumferentially away from central portion 162. In various embodiments, the lateral portions 166 are further from the top panel 114 than the entirety of the first weakened section 130, and central portion 162 is further from the top panel 114 than the lateral portions 166. Central portion 162 is distance 164 from top panel 114, and lateral portions 166 are distance 168 from top panel 114, and distance 168 is less than distance 164.

[0041] Closure 110 includes a plurality of weakened section extensions 170 that each extend, from one or more of the central portion 162 and the lateral portions 166, towards at least one of the top panel 114 and the other weakened section extension 170. As one example, weakened section extensions 170 include first extension 174 extending towards a first extension end 175 and second extension 176 extending towards a second extension end 177. In various embodiments, each of first extension 174 and second extension 176 extend from lateral portions 166 towards each other. In various embodiments, each of the plurality of weakened section extensions 170 extend from the second weakened section 160 at least in part towards the top panel 114 (e.g., closure 110, closure 210, closure 310, closure 410, and closure 510). Weakened section extensions 170 (e.g., first extension end 175 and second extension end 177) define angle 172 between extensions 174. In various embodiments, angle 172 is at least 10 degrees and less than angle 136. In various embodiments, angle 172 is at least 20 degrees less than angle 136. In various embodiments, angle 172 is at least 30 degrees less than angle 136.

[0042] In various embodiments, at least one of the plurality of extensions (e.g., extensions 174) extends at least as close to the top panel (e.g., top panel 114) as the first weakened section (e.g., first weakened section 130), such as closure 310, closure 410, and closure 510. In various embodiments, at least two of the plurality of extensions extends at least as close to the top panel as the first weakened section, such as closure 310, closure 410, and closure 510. In various embodiments, at least one of the first extension end and the second extension end is closer to the top panel than the first weakened section, such as closure 310, closure 410, and closure 510. In various embodiments, the first extension end is closer to the top panel than the first end, such as closure 310, closure 410, and closure 510.

[0043] First weakened section 130 and weakened section extensions 170 collectively define torsion axis 144, about which closure 110 deforms when closure 110 pivots from the closed position to the open position.

[0044] When the closure 110 is opened, most or all of the frangible members 138 are broken, and the retention band 150 remains engaged with the container neck 192. Cylindrical wall 122 of closure 110 remains attached to the retention band 150 via tethers 154. Tab 142 interacts with the mating attachment formation to maintain an open cap position wherein the cylindrical wall 122 of closure 110 is retained displaced from the opening of the container 190.

[0045] In various embodiments, each of plurality of weakened section extensions 170 define a portion of a tab 142 extending away from the top panel 114 towards the retention band 150, the tab 142 defined by the second weakened section 160, the tab 142 interfacing against the container neck 192 to bias the top panel 114 away from an opening of the container neck 192 subsequent to the closure 110 being opened.

[0046] The tab 142 interacts with the mating attachment formation / engagement ring of the container neck 192 to maintain an open cap position wherein the cylindrical wall 122 of closure 110 is retained displaced from the opening of the container 190. The tethers 154 bias the tab 142 inward towards the neck portion 192 of the container 190, working together with the tab 142 to keep the cylindrical wall 122 in the open cap position on an angle θ (e.g., from 90° to 180°). In a specific embodiment, the tab 142 contacts the neck (e.g., the TE bead on the neck, the thread) while the cylindrical wall 122 is in the open cap position.

[0047] Referring to FIGS. 4-12, a series of images of closure 110 being opened are shown. When closure 110 is initially opened, J-band 152 engages against container neck 192 (e.g., see FIG. 6) to bias retention band 150 downward until frangible members 138 are broken.

[0048] When closure 110 is fully opened (e.g., see FIGS. 11-12), tab 142 interfaces against container neck 192 to bias top panel 114 and other portions of closure 110 away from the opening of the container neck 192. As a result, users can access, such as drink from, container 190.
