The closure () also has a sealing rib () having a first sealing portion () which is contiguous with the top portion (). The first portion () has an inner surface made up of at least a first substantially cylindrical surface portion () lying radially inwardly of the first surface portion (). The rib () further includes a second sealing portion () that is separated from the top portion () by the first portion () and which, prior to attachment of the closure to the container, extends inwardly to a free edge. The closure () further has a continuous nub member () extending downwardly and outwardly from the underside of the top portion () and positioned radially inwardly of the first sealing portion (). On relative attachment of the closure to the container end portion, the nub member () seals with an inner surface of the container end portion and the sealing rib () seals with at least an outer surface of the container end portion.

Linerless bore seal closure

A closure () that is suitable for attachment to a container () having an end portion defining an opening of the container. The closure comprises a top (), a skirt (), a support ring () that is engageable with the end portion of the container and which is hingedly connected to the skirt (), and a sealing rib (). The sealing rib () has a first portion () and a second portion (). The length of the second portion () is such that, during attachment of the closure () with the end portion of the container (), the end portion of the container contacts the second portion () and pushes it upwardly and at least towards the first portion () so as to form a seal between the end portion of the container () and the closure ().

Flip top closure

A plastic closure for sealing a container, the closure having a top portion and a skirt portion depending from the top portion. The closure has an annular sealing rib which extends within the cavity defined by the top portion and the skirt portion. The rib includes a first portion having a substantially cylindrical inner surface extending away from the underside of the top portion and disposed radially inward of the skirt and a second, frusto-conical, portion contiguous with the end of the first portion distal to the underside of the top portion and extending radially inwardly and terminating in a circular free edge, such that during engagement of the cap with the neck of the container, the second, frusto-conical, portion will be engaged by the free end of the neck and folded back against the first portion of the rib to form a gas-tight seal between the neck of the container and the closure.

Linerless closure for carbonated beverage container

A closure () having a sealing rib () projecting downwardly from the underside of its top portion (). The first portion () of the sealing rib () increases in thickness as it extends away from the top portion (). In another aspect, the invention relates to a closure () in which the sealing rib () has a third portion () that is substantially no thicker than the second portion () of the rib () and has a length longer, and preferably substantially longer, than its thickness. In the second aspect, the third portion () of the rib () is connected to the second portion () at or adjacent its free edge and extends generally in a direction away from the top portion (). Upon attachment of the closure () with the neck () of a container, the third portion () will be displaced to lie between the end portion () of the neck () of the container and the top portion () of the closure ().

Closure with extended seal member

A package made up of a container () with a closure assembly () applied thereto. The closure assembly has a molded plastic closure element () with a top panel () and an annular skirt () that depends downwardly from the. top panel and surrounds and engages a finish of the container. The closure assembly () also has a barrier disc () that underlies the top panel, but is out of engagement with a rim () of the container () when the closure assembly is applied to the container. The closure element has an integral sealing fin () with an inner end () as a first portion and an outer end () as a second portion, and the outer end, as molded, extends inwardly and downwardly from a distal end of the first portion. When the closure assembly is applied to the container, the second portion of the sealing fin is folded back toward the inner end of the sealing fin and engages the rim and a terminal side portion () of the finish of the container to form a top and side seal between the closure assembly () and the container (). The outer end of the sealing fin also traps the sealing disc against the underside of the top panel of the closure but out of engagement with the container. The barrier disk disc is molded or fabricated from a material, for example, EVOH or LCP, that has excellent resistance to the permeation of Oor other gases therethrough, and may have an oxygen-scavenging material embedded therein when it is desired to use a closure assembly with such a barrier liner for the packaging of oxygen-sensitive materials, such as beer and other malt beverage products, dairy products and real juices.

Closure

Container and linerless closure combination

A closure ( ) for mounting onto a container ( ), the closure ( ) including a top portion ( ) and a skirt portion ( ) depending from the top portion ( ). An annular sealing rib ( ) projects downwardly from an underside of the top portion ( ). The rib ( ) includes a first portion ( ) which is contiguous with the top portion ( ) and has an inner surface ( ) which lies radially inwardly of the skirt portion ( ) and at least a second, frusto-conical, portion ( ) contiguous with the first portion ( ) and separated from the top portion ( ) by the inner surface ( ) of the first portion ( ). The second portion ( ) has an upper side and an underside and extends radially inwardly to a circular edge. The inner surface ( ) of the first portion ( ) has an internal diameter relative to the external diameter of the end portion ( ) of the container ( ) to which the closure is to be attached such that during attachment of the closure with the end portion of the container, the sealing rib ( ) is engaged by the end portion of the container so folding the second portion ( ) at least towards the inner surface ( ) of the first portion ( ) of the rib to form a seal between at least an outer surface of the end portion of the container and the closure. The closure further has an annular protrusion ( ) formed on the underside of the second portion ( ) which extends outwardly therefrom. The protrusion ( ), on attachment of the closure with the end portion, engages the outer surface of the end portion ( ) so causing the sealing rib ( ) to be disposed over a greater area of the outer surface of the end portion of the container.

Closure with seal member

A container closer particularly for use on screw top containers such as carbonated beverage containers, the container closure having a generally cylindrical continuous tamper evident band joined by a plurality of frangible bridges to the free edge of a skirt of the closure. The band has a segmented internal rib which engages an external retaining flange of the container when the closure is applied to the container so that on removal of the closure the tamper evident band remains on the container or is visually clearly damaged by removal of the closure from the container. The band is provided with longitudinal reinforcement by projections or other areas of thickening to provide the band with longitudinal stiffness while still permitting it to expand over the retaining flange on the container. The rib has an first annular side, the first annular side having a compound surface comprising a radially outer frusto-conical portion which assists in the molding of the rib and a radially inner substantially planar portion which increases the difficulty of removing the closure intact from the container without rupturing the bridges joining the tamper evident band from the remainder of the closure.

Tamper evident closure

A closure ( ) having a sealing rib ( ) projecting downwardly from the underside of its top portion ( ). The first portion ( ) of the sealing rib ( ) increases in thickness as it extends away from the top portion ( ). In another aspect, the invention relates to a closure ( ) in which the sealing rib ( ) has a third portion ( ) that is substantially no thicker than the second portion ( ) of the rib ( ) and has a length longer, and preferably substantially longer, than its thickness. In the second aspect, the third portion ( ) of the rib ( ) is connected to the second portion ( ) at or adjacent its free edge and extends generally in a direction away from the top portion ( ). Upon attachment of the closure ( ) with the neck ( ) of a container, the third portion ( ) will be displaced to lie between the end portion ( ) of the neck ( ) of the container and the top portion ( ) of the closure ( ).
