Abstract
Disrupted closures are described herein which can provide for consistent flow paths for gas transfer from a container. The closures include a sealing member extending on the inside of the closure to contact a vented liner and/or the rim of a container. The sealing member includes a sealing portion and one or more disruptions in the sealing portion to provide gas pathways to the ambient atmosphere.
Claims23
A closure for a container, the closure comprising:
- an upper wall;
- a sidewall extending downwardly from the upper wall;
- and
- a sealing member positioned inwardly from the sidewall and extending from at least one of the upper wall and sidewall, the sealing member being annular and having a sealing portion configured to contact a sealing surface when installed on the container, the sealing portion including a plurality of disruptions in the sealing surface prior to installation on the container to permit fluid to pass inward and outward between an interior of the container and the ambient atmosphere between the sealing portion and sealing surface when installed on the container, wherein the plurality of disruptions have a width of about 0.005 inches to about 0.030 inches.

A closure for a container, the closure comprising:
- an upper wall;
- a sidewall extending downwardly from the upper wall;
- and
- a sealing member positioned inwardly from the sidewall and extending from at least one of the upper wall and sidewall, the sealing member including a sealing portion and a plurality of disrupted portions,
- the sealing portion including a sealing cross-sectional profile configured to contact a sealing surface when installed on the container,
- the plurality of disrupted portions having a cross-sectional profile that are different from the sealing cross-sectional profile creating at least one of a gap and a decreased height compared to the sealing cross-sectional profile prior to installation on the container, the plurality of disrupted portions permitting fluid to pass inward and outward between an interior of the container and the ambient atmosphere between the sealing member and the sealing surface when installed on the container, wherein the plurality of disrupted portions have a width of about 0.005 inches to about 0.030 inches.
3 more elements
A method of manufacturing a closure for a container, the method comprising the steps of:
- providing a closure having an upper wall, a sidewall extending downwardly from a periphery of the upper wall, and a sealing member extending downwardly from at least the upper wall and sidewall, the sealing member being annular and having a sealing portion configured to contact a sealing surface when installed on the container;
- and
- creating a plurality of disruptions in the sealing portion of the sealing member by using a tool that is heated to cause the plurality of disruptions to be permanent, the plurality of disruptions resulting in at least one of a gap and a decreased height relative to the sealing portion, the plurality of disruptions permitting fluid to pass inward and outward between an interior of the container and the ambient atmosphere between the sealing member and the sealing surface when installed on the container.
