Abstract
A vented sealing member is provided for sealing to a rim of a container. The vented sealing member may provide for an exchange of fluid, such as gas, between an interior space of the container and the ambient atmosphere. This exchange may be necessary as pressure internal to the container may increase and/or decrease at various times, such as after manufacture and shipment. The vented sealing member is also configured to dispense the contents of the container when an upper member, such as a tabbed member, is removed from the sealing member.
