The lid is adapted to engage a top of the at least one wall when the container is in a closed position, and includes a second surface disposed near a bottom of the lid. A foam gasket is permanently attached to and located on one of the first and second surfaces, and provides a seal between the lid and the body when the container is in a closed position. The gasket is attached to the surface while in fluid form.
