[0018] Referring generally to the figures, various embodiments of a closure are shown. The closure includes a liner. The liner is formed from a material that provides a reduced coefficient of friction when attached to aluminum containers compared to other closures, such as closures that include a liner including rubber. The liner extends through at least part of the engagement, such as threading, between the closure and the container neck. Applicant has observed that reducing the coefficient of friction of the liner facilitates a user opening the closure. Thus, various embodiments include a liner that extends lower than the engagement element of the closure, such as the threading. Extending the liner through the threading reduces the frictional resistance to opening the closure and thus provides an improved user experience when opening the closure.

[0019] Referring to FIGS. 1-5, a closure 110 for closing a container 190 according to an embodiment is shown. Closure 110 includes top panel 120 and liner 150 coupled together. In various embodiments, top panel 120 and liner 150 are centered on axis 112. In various embodiments, the closure 110 is a roll on pilfer proof (ROPP) closure. In various embodiments, top panel 120 and liner 150 are coupled together, such as rigidly coupled.

[0020] Top panel 120 is centered on axis 112. Top panel 120 defines upper surface 122 and an opposing lower surface 124. Top panel 120 includes body skirt 130 extending downward from periphery 126 of top panel 120, such as from lower surface 124 of top panel 120 at periphery 126. In various embodiments, body skirt 130 extends circumferentially around axis 112, and is centered on axis 112. Body skirt 130 includes a plurality of knurls 132 extends radially outward from body skirt 130 with respect to axis. Knurls 132 are configured to facilitate a user opening closure 110 from container neck 192 of container 190.

[0021] In various embodiments, body skirt 130 is formed from a material including a metal, such as aluminum. In various embodiments, body skirt 130 is formed from a material including a metal.

[0022] Closure 110 is coupled to container neck 192 via a container engagement element, such as threading 142 (shown schematically in FIG. 3). Threading 142 is located in engagement element section 140 of body skirt 130. Top 144 of threading 142 defines distance 145 from lower surface 124 of top panel 120, and bottom 146 of threading 142 defines distance 147 from lower surface 124 of top panel 120.

[0023] Liner 150 includes upper panel 152. Upper panel 152 defines upper surface 154 and opposing lower surface 156. In various embodiments, liner 150 is rigidly coupled to top panel 120 via an adhesive that rigidly couples upper surface 154 of upper panel 152 to lower surface 124 of top panel 120. Liner 150 further includes liner skirt 160 extending downward from periphery 158 of liner 150, such as from lower surface 156. Liner skirt 160 extends to a lower end 162, which defines distance 164 from lower surface 124 of top panel 120.

[0024] Closure 110 includes sealing formation 170, which is configured to seal contents of container 190 within container 190. In a specific embodiments, sealing formation 170 includes inner wall 172, outer wall 176, and central wall 180 extending from lower surface of upper panel 152, such as away from top panel 120. Inner wall 172 is radially closer to axis 112 than outer wall 176 and central wall 180, and central wall 180 is radially closer to axis 112 than outer wall 176.

[0025] Referring to FIG. 5, various aspects of closure 110 being coupled to container neck 192 of container 190 are shown. In various embodiments, container neck 192 interfaces with one or more of outer surface 174 of inner wall 172, inner surface 178 of outer wall 176, and bottom surface 182 of central wall 180, or more specifically two or more of outer surface 174, inner surface 178, and bottom surface 182, or even more specifically all three of outer surface 174, inner surface 178, and bottom surface 182. The interface between container neck 192 and the one or more of outer surface 174, inner surface 178, and bottom surface 182 seals most and / or all of contents of container 190 within container 190.

[0026] In various embodiments, liner 150 is formed from a material including a plastic. In various embodiments, the coefficient of friction between the liner 150 and a metal container (e.g., an aluminum container) the closure 110 is coupled to is sufficiently low to facilitate closure 110 being opened compared to if the liner 150 was formed from rubber and / or if liner 150 did not extend between threading 142 of closure 110 and threading of container neck 192. In various embodiments, liner 150 is formed from including low-density polyethylene (LDPE). In various embodiments, liner 150 is formed from a low durometer material. Applicant has observed that providing such a liner as described herein improves the user experience for opening the closure 110, such as by providing a more consistent and / or reduced amount of force to initially open the closure 110 from the container 190.

[0027] Referring to FIGS. 6-8, various aspects of closure 210 are shown. Closure 210 is structurally and functionally the same as closure 110 except as otherwise provided.

[0028] Closure 210 includes top panel 220 and liner 250 coupled together. In various embodiments, top panel 220 and liner 250 are centered on the same axis. In various embodiments, the closure 210 is a roll on pilfer proof (ROPP) closure. In various embodiments, top panel 220 and liner 250 are coupled together, such as rigidly coupled.

[0029] Top panel 220 defines upper surface 222 and an opposing lower surface 224. Top panel 220 includes body skirt 230 extending downward periphery of top panel 220, such as from lower surface 224 of top panel 220 at the periphery. In various embodiments, body skirt 230 extends circumferentially around the same axis as top panel 220 and liner 250. Closure 210 is coupled to container neck 192 via a container engagement element, such as a threading.

[0030] Liner 250 includes upper panel 252. Upper panel 252 defines upper surface 254 and opposing lower surface 256. In various embodiments, liner 250 is rigidly coupled to top panel 220 via an adhesive that rigidly couples upper surface 254 of upper panel 252 to lower surface 224 of top panel 220. Liner 250 further includes liner skirt 260 extending downward from periphery 258 of liner 250, such as from lower surface 256. Liner skirt 260 extends to a lower end 262.

[0031] Closure 210 includes sealing formation 270, which is configured to seal contents of container 190 within container 190. Sealing formation 270 includes projection 272, which defines outer surface 274 facing away from the central axis, opposing inner surface 276 facing towards the central axis, and bottom surface 278 facing away from top panel 220.

[0032] Referring to FIG. 8, various aspects of closure 210 being coupled to container neck 192 of container 190 are shown. In various embodiments, container neck 192 interfaces with bottom surface 278 of projection 272 to seal contents of container 190 within container 190.
