Closure with plug and container

A package comprising:

• a container having a finish defining an opening, the container having an external thread formation on the finish;
• and
• a polymeric closure being configured for fitment to the finish of the container for closing the opening of the container, the polymeric closure comprising a first closure portion including a top wall portion and an annular skirt portion, the top wall portion including a plurality of polymeric plug seals extending downwardly therefrom, the plurality of polymeric plug seals extending around a circumference of the polymeric closure with a respective space located between each of the adjacent polymeric plug seals, the respective space extending from the top wall portion to an interior of the first closure portion such that each of the plurality of polymeric plug seals is discrete and separate from the remaining ones of the plurality of plug seals, the annular skirt portion depending from the top wall portion, the annular skirt portion having an interior surface, the interior surface of the annular skirt portion including an internal thread formation for mating engagement with the external thread formation of the container,
• wherein the plurality of polymeric plug seals is spaced from the interior surface of the annular skirt portion and assists in sealing with the container,
• wherein the plurality of polymeric plug seals provides a seal with the finish of the container across at least 40 to about 90 percent of the finish.
