Abstract
There is disclosed a container lid having features which especially adapt it for use with beverage containers. The lid comprises a pair of tear impressions which define therebetween an access strip. After assembly of the lid to a container the access strip is pulled back from the rim of the lid along its tear impressions to create ready access to the contents. The access strip may be reclosed to the container to alleviate the problem of contents spillage during transport or motion of the container and further to preserve the thermal state of the contents.
