Abstract
A closure for a container is provided with a top portion and a skirt depending from an outer periphery of the top portion. A generally circular rim extends downwards from the lower surface of the top portion. A liner is attached to the closure between an outer surface of the rim and an inner surface of the skirt. The liner is configured to provide a fluid tight seal for containers having varied neck dimensions and/or profiles. One or more projections extend into a space formed between the lower surface of the top portion, an inner surface of the skirt, and an outer surface of the rim, with the liner enveloping and being supported in the closure by the one or more projections.
Claims18
A closure for a container, the closure centered about a longitudinal axis and comprising:
- a top panel;
- an annular skirt extending downwardly from a lower surface of the top panel;
- an engagement element extending from the annular skirt that attaches the closure to a container;
- a circular rim extending downwards from the lower surface of the top panel, the rim terminating at a lower end lying along a generally horizontal plane, the rim being radially further from the longitudinal axis than the annular skirt;
- a space defined between the lower surface of the top panel, an inner surface of the annular skirt, an outer surface of the rim, and the plane on which the lower end of the rim terminates;
- a plurality of projections extending into or through the space, a first projection of the plurality of projections attached to the inner surface of the annular skirt and the outer surface of the rim;
- and
- a liner located within the space, the liner attached to and supported by the plurality of projections.
A closure for a container, the closure centered about a longitudinal axis and comprising:
- a top panel;
- an annular skirt extending downwardly from a lower surface of the top panel;
- an engagement element extending from the annular skirt that attaches the closure to a container;
- a circular rim extending downwards from a lower surface of the top panel, the rim terminating at a lower end lying along a generally horizontal plane, the rim being radially further from the longitudinal axis than the annular skirt;
- a space defined between the lower surface of the top panel, an inner surface of the annular skirt, an outer surface of the rim, and the plane on which the lower end of the rim terminates;
- a plurality of projections attached to at least one of the inner surface of the annular skirt, the lower surface of the top panel, and the outer surface of the rim, a first projection of the plurality of projections extending from the lower surface of the top panel at a first angle, a second projection of the plurality of projections extending from the lower surface of the top panel at a second angle different from the first angle, and a third projection of the plurality of projections is attached to the inner surface of the annular skirt and the outer surface of the rim;
- and
- a liner located within the space, the liner attached to and supported by the plurality of projections.

- a circular rim extending downwards from a lower surface of the top panel, the rim terminating at a lower end lying along a generally horizontal plane, the rim being radially further from the longitudinal axis than the annular skirt;
- a space defined between the lower surface of the top panel, an inner surface of the annular skirt, an outer surface of the rim, and the plane on which the lower end of the rim terminates;
- a plurality of projections extending from at least one of the lower surface of the top panel, the outer surface of the circular rim, and the inner surface of the annular skirt, a first projection of the plurality of projections comprising one of a hook structure and an aperture, wherein the first projection comprises an aperture, the first projection extending from at least two of:
- the lower surface of the top panel;
- the inner surface of the annular skirt;
- and
- the outer surface of the rim;
- and
- a liner located within the space, the liner attached to and supported by the plurality of projections.
