US 12,668,407 B2 · Container and metallic closure with a floating liner

Abstract

The present disclosure generally relates to the manufacture and sealing of containers formed of metallic material or glass with metallic closures, and more specifically to an apparatus and methods used to seal containers with a Roll-on Pilfer Proof (ROPP) closure or a prethreaded closure. The closure includes a floating liner that is not attached to the closure such that the liner can move relative to a lower surface of the closure. The floating liner may comprise a polymer, a metal, a high-durometer material, and/or an elastic material. The floating liner includes an inner plug seal that seals or seats on an inner surface of a curl of the container. The floating liner can optionally include an outer alignment support configured to align with and/or be positioned adjacent to an outer surface of the curl.

Dependent claims

A closure for sealing a metallic bottle, comprising:

a closure shell, comprising:
a top portion with an upper surface that is generally circular and a lower surface opposite the upper surface;
a closure body extending from the top portion;
and
a plurality of retaining elements formed around a circumference of the closure body, each retaining element projecting inwardly toward a longitudinal axis extending through a center of the top portion;
and
a floating liner positioned within the closure body proximate to the lower surface, the floating liner comprising:
a top surface that is generally circular, the top surface positioned proximate to the lower surface of the closure shell;
and
an inner plug seal extending away from the top surface, wherein the top surface is movable relative to the lower surface such that the inner plug seal can move laterally relative to the longitudinal axis, and wherein the plurality of retaining elements retain the floating liner within the closure body.

A metallic bottle with a closure that is selectively removable, comprising:

the closure, comprising:
a top portion with an upper surface and a lower surface opposite the upper surface;
a closure body extending from the top portion;
a plurality of retaining elements formed around a circumference of the closure body, each retaining element projecting inwardly toward a longitudinal axis extending through a center of the top portion;
and
a floating liner positioned within the closure body proximate to the lower surface, the floating liner comprising:
a top surface that is generally circular, the top surface facing the lower surface of the closure, wherein the top surface of the floating liner is not attached to the lower surface to permit movement of the floating liner relative to the lower surface;
and
an inner plug seal extending away from the top surface, wherein the inner plug seal can move laterally relative to the longitudinal axis, and wherein the plurality of retaining elements retain the floating liner within the closure body;
and
the metallic bottle, comprising:
a body portion having a sidewall extending upwardly from a closed bottom;
a neck portion extending upwardly from the sidewall;
container threads formed on at least a portion of the neck portion;
and
a curl at an uppermost portion of the neck portion, the curl defining an open end opposite the closed bottom, wherein the inner plug seal of the floating liner contacts an inner surface of the curl to seal the metallic bottle.
