Removable locking container lid with outer skirt
View Patent ↗A container lid for use with a container with a neck. The lid includes a top and bottom, a skirt extending downward from the circumference of the lid, and a circumferential flange extending radially outward from the lid. The skirt preferably includes at least one integral bead shaped to engage the neck or rim of the container. The lid preferably includes a convex center section including at least one vent. The at least one vent is preferably integral with the lid, and is opened by the steam pressure buildup inside the container when the contents are heated. When the cover is locked on the container, the skirt provides a seal against the outside of the container neck.
1. A removable locking container lid for covering a container having neck including an outwardly protruding rim, the lid comprising:
a top, a bottom, and a circumferential edge;
a skirt extending downward from the lid at or near the circumferential edge, the skirt having a bottom edge, an inner surface and an outer surface, the inner surface shaped to removably attach to the outside of the container neck; and
a circumferential flange extending radially outward from the lid, the flange having at least two first portions located approximately at the top of the skirt and extending radially outward from the outer surface of the skirt, at least two second portions located approximately at the bottom of the skirt and extending radially outward from the outer surface of the skirt, and each end of a first portion being connected to a corresponding end of a second portion by a transition section;
wherein the skirt includes at least one integral bead protruding inwardly from the inner surface of the skirt at a location opposite each of the second portions to engage a bottom surface of the outwardly protruding rim of the container neck;
wherein at least one second portion includes a contoured gripping surface defined by at least three arcuate segments that form finger grips; and
wherein the skirt extends above a portion of the top such that the first portion of the flange is located above the top at its circumferential edge while the second portion of the flange is located below the top at its circumferential edge.
2. The container lid of claim 1 , wherein the second portions of the flange are located on substantially opposite sides of the lid.
3. The container lid of claim 1 , wherein the skirt includes at least two integral beads, each bead located adjacent to a gripping section.
4. The container lid of claim 1 , wherein the lid includes a center section located on the top surface of the lid, the center section including a lower annular surface circumscribing an upper portion, the upper portion including at least one venting door which is adapted to permit air to pass from one side of the lid to the other under certain conditions.
5. The container lid of claim 4 , wherein the at least one venting door is formed from a cut portion of the lid and attached to the lid on one side so as to create a living hinge.
6. The container lid of claim 4 , wherein the center section includes a series of venting doors arranged in a circular pattern around the center point of the lid, the venting doors being substantially equidistant from the center and spaced substantially equally apart from each other.
7. The container lid of claim 1 , wherein the lid is circular in shape and wherein the flange is located on a radially outer edge of the top.
8. A removable locking container lid for covering a container having a neck, the lid comprising:
a top, a bottom, and a circumferential edge;
a skirt extending downward from the lid at or near the circumferential edge, the skirt having a bottom edge, an inner surface and an outer surface, the inner surface being shaped to removably attach to the outside of the container neck; and
a circumferential flange extending radially outward from the lid, the flange having at least one first portion located approximately at the top of the skirt and extending radially outward from the outer surface of the skirt, at least one second portion located approximately at the bottom of the skirt and extending radially outward from the outer surface of the skirt, and a transition section joining one end of the first portion and one end of the second portion;
wherein the skirt includes an integral bead protruding inwardly from the inner surface of the skirt at a location opposite the second portion the flange to engage a bottom surface of an outwardly protruding rim of the container neck;
wherein the at least one second portion includes a contoured gripping surface defined by at least three arcuate segments that form finger grips; and
wherein the skirt extends above a portion of the top such that the first portion of the flange is located above the top at its circumferential edge while the second portion of the flange is located below the top at its circumferential edge.
9. The container lid of claim 8 , wherein the lid includes a center section located on the top surface of the lid, the center section including a lower annular surface circumscribing an upper portion, the upper portion including at least one venting means which is adapted to permit air to pass from one side of the lid to the other under certain conditions.
10. The container lid of claim 9 , wherein the at least one venting means is an integral vent door with a living hinge, the door adapted to open when the difference in pressure on opposite sides of the lid exceeds a threshold value.
11. The container lid of claim 8 , wherein the flange includes at least two first portions and at least two second portions, and wherein each end of a first portion is connected to a corresponding end of a second portion by a transition section.
12. The container lid of claim 9 , wherein the at least one venting means is a plurality of integral vent doors arranged in a circular pattern, each door having a living hinge at a radially outward edge of the door such that when the vent door opens, venting air is directed toward the center of the lid.
