Abstract

closure (14) includes an overcap (18) having an annular skirt (44), and an annular wall (48) extending inwardly from the skirt. A lid (20) is carried by the overcap radially within the annular skirt, and includes a hub (50), and an annular margin (52) extending radially outwardly with respect to the hub and having upper surfaces and lower surfaces . An annular container seal (22) extends circumferentially continuously around the annular margin. One or more vents (54) 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 (24) are disposed at the one or more vents between the lid and the overcap. The proposed invention allows for external air to enter the package on loosening the overcap, aiding removal of the lid.

Claims (26)

Claims A closure that includes: an overcap, including: 5
1. an annular skirt extending along a longitudinal axis A, 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 10 15 20 25 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.
2. The closure set forth in claim 1 wherein the annular wall is an annular flange establishing a central aperture of the overcap, and wherein the annular margin of the lid is overlapped by the annular flange and is established radially outwardly of the central aperture of the overcap.

17. The package set forth in claim 14 wherein the container seal and the one or more vent seals are connected to one another at a lower surface of the lid.
18. The package set forth in claim 14 wherein the container seal and the one or more vent seals are separate, and not connected to one another.
19. The package set forth in claim 14 wherein the container includes at least one container snap bead and the overcap of the closure includes a corresponding closure snap bead for snap fit cooperation with the container snap bead .
20. The package set forth in claim 14 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 to open the vent. 16
21. The package set forth in claim 20 wherein the lugs includes cooperating ramps.
22. 5 10 15 The package set forth in claim 20, wherein the lower surface of the overcap includes a plurality of the first lug circumferentially spaced and the upper surface of the lid includes a corresponding plurality of the second lug circumferentially spaced for cooperation with the plurality of the first lug to displace the overcap from the lid to open the vent.
23. The package set forth in claim 14, wherein upon initial rotational removal of the closure from the container, the one or more vent seals become unseated.
24. The closure set forth in claim 1, wherein the overcap is rotatable with respect to the lid so as to unseat the one or more vent seals.
25. The closure set forth in claim 1, wherein one or more vent seals are disposed at the one or more vents and connected to the annular container seal at the lower surface of the annular margin.
