Abstract
A pressware product includes a top piece and a bottom piece. The top piece includes a planar central portion, a sidewall extending from the central planar portion, and a flange extending horizontally from the sidewall. The flange includes a slot and a radially extending top groove. The bottom piece cooperatively defines an inner space with the top piece. The bottom piece includes a planar central portion, a sidewall extending from the central planar portion, and a flange extending horizontally from the sidewall. The flange includes a locking flap configured to engage the slot of the top piece and a radially extending bottom groove. The radially extending bottom groove cooperatively defines a channel with the top groove so that the channel is in fluid communication with the inner space.
