Abstract
The invention is directed to storage containers and lids for storage containers which provide for a secure closure and a storage container which is airtight and leakproof. The lid includes a generally U-shaped closure made of a plastic material for securing to a container base; a center window also made of a plastic material and preferably the same as the U-shaped closure; and a thermoplastic material which provides for a sealing gasket on the underside of the U-shaped closure for mating with the container base and a perimeter seal on the outside of the U-shaped closure and around the outer circumference of the center window. The lid may further include a gripping tab made at least in part of thermoplastic material in the lid corner for opening or closing the container, and wings made of a thermoplastic material in one or more portions or corners of the lid.
