Abstract
A closure includes an overcap having an annular skirt, and an annular wall extending inwardly from the skirt. A lid is carried by the overcap radially within the annular skirt, and includes a hub, and an annular margin extending radially outwardly with respect to the hub, and having upper and lower surfaces. An annular container seal extends circumferentially continuously around the annular margin. One or more vents may extend through the annular margin between the upper and lower surfaces thereof at one or more discrete circumferential locations radially inward with respect to the container seal. One or more vent seals may be disposed at the one or more vents between the lid and the overcap.

A closure that includes:
- an overcap, including:
- an annular skirt extending along a longitudinal axis, and
- an annular wall extending radially inwardly from the annular skirt;
- a lid carried by the overcap radially within the annular skirt, and including:
- a hub, and
- an annular margin extending radially outwardly with respect to the hub, and having upper and lower surfaces;
- and
- an annular container seal extending circumferentially continuously around the annular margin,
- wherein the lid further includes one or more vents extending through the annular margin between the upper and lower surfaces thereof at one or more discrete circumferential locations, and wherein the container seal is disposed radially outwardly with respect to the one or more vents, and the closure further includes one or more vent seals disposed at the one or more vents between the lid and the overcap.
A closure that includes:
- an overcap, including:
- an annular skirt extending along a longitudinal axis, and

- a hub, and
- an annular margin extending radially outwardly with respect to the hub, and having upper and lower surfaces;
- and
- an annular container seal extending circumferentially continuously around the annular margin
- wherein a lower surface of the overcap includes a first lug and an upper surface of the lid includes a corresponding second lug for cooperation with the first lug to displace the overcap from the lid.
