ABSTRACT:
The present invention relates to a container constructed of a material with a stiffness coefficient of less than one-tenth (0.10) millimeter per ounce over the wall material's elastic range and having a continuous edge region defining an opening in the container, and comprises a closure and method for providing a closure which provides a substantially air-tight and reuseable seal over the entire area of the container opening, the closure and method therefor comprise; a rigid anchor means interconnectable with the edge region of the container and defining an opening for providing a path for the movement of the contents of the container through the anchor means and for providing a rigid anchor on the edge region of the container; a means for sealing the interconnection between the rigid anchor means and the edge region of the container in a substantially air-tight relation; a cover means interconnectable with the opening defined by the anchor means for covering the opening defined by the anchor means; and, a means for removably sealing the interconnection between the rigid anchor means and the cover means for providing a removeable and resealable, substantially air-tight seal of the opening defined by the anchor means.
The substantially air-tight sealing of the interconnection of the anchor means and the edge region of the container and the substantially air-tight sealing of the opening defined by the anchor means both act to provide a substantially air-tight and reuseable seal of the container opening.
