Abstract:
A lid for a container having a sidewall with a rim defining an opening into the container, said lid being engageable with the rim to close the opening, said lid being stackable with another substantially identical lid, said lid comprising:a central panel having an outer perimeter; a hinge extending transversely across said central panel and dividing said lid into two lid portions, one lid portion being pivotably movable about said hinge relatively to the other said lid portion; a resilient, flexible skirt joined to said perimeter and extending substantially perpendicularly to the plane of said central panel, said skirt having an inside surface positionable to face the container sidewall adjacent to the rim and a pair of weakened regions arranged on opposite sides of said lid, said weakened regions being aligned with said hinge and subject to failure to facilitate separation of said skirt at said hinge when said one lid portion is pivoted relatively to the other said lid portion; a detent positioned adjacent to one of said weakened regions and projecting substantially perpendicularly from said inside surface of said skirt on said one lid portion, said detent being resiliently biasable into engagement with the rim by said skirt and, when said lid is engaged with the rim, said detent cooperating with the rim to hold said one lid portion in a pivoted position relatively to the other said lid portion thereby exposing the opening in the container; and a stacking lip joined to said perimeter of said central panel and extending substantially perpendicularly to the plane of said central panel away from said skirt, said lip being engageable with the inside surface of the skirt on the other substantially identical lid for stacking a plurality of lids one atop another, said lid having a notch aligned with said hinge and sized to receive a detent on the other substantially identical lid.
