Abstract
A dispensing liner for a container includes a seal element having a sealing edge and a central portion. The sealing edge is engaged with and sealed to a land portion of a container to close the opening in the container. The seal element includes a preferentially formed score line having a first frangible portion and a second portion defining a removable tab. The first frangible portion and the second portion are formed within the central portion of the liner with the second portion in spaced relation and adjacent to the sealing edge. The liner is opened along at least the first frangible portion to define a dispensing port. The periphery of the liner, at the sealing edge, forms a seal with the cap when the cap is engaged with the container after the liner is opened. The tab can be removed from the liner leaving the sealing edge in place to effect a seal between the liner and the cap.
