Abstract: A lid for a container is disclosed. The crown of the lid includes a peripherally extending skirt and an outwardly extending spout. The skirt is adapted to secure the crown to the container. The spout includes a single slit and is adapted to deform about the single slit with application of a pressure differential.

Abstract: An apparatus and method for packaging sheet material. The apparatus comprises a housing, a first forming guide, and a banding unit. The housing defines a cylindrical cavity which is open at both ends and includes a longitudinal opening which intersects the cylindrical cavity. The first forming guide is affixed to the housing adjacent the longitudinal opening and extends into the cylindrical cavity. The banding unit is disposed adjacent the downstream end of the cylindrical cavity. The method comprises imparting a U-shaped form upon a stack of sheet material by insertion of the stack into the upstream end of a cylindrical cavity. The U-shaped stack of sheet material is then moved toward and out of the downstream end of the cylindrical cavity. Finally, the U-shaped stack is banded as the stack emerges from the cylindrical cavity.

Abstract: A container comprising at least one receptacle wall defining an opening. A brim is formed about the opening. The brim includes a brim curl in a first configuration. The brim curl is adapted to deform into a second configuration. The container may further comprise a lid removably and sealingly engaged to the receptacle. The lid is adapted to deform the brim curl upon removal of the lid from the receptacle. The lid cannot sealingly engage the deformed brim curl.
