Abstract: A food tray has upper and lower tray shaped members and an informational insert sandwiched between them for viewing of an informational display of the insert through a transparent or translucent window portion of at least one of the tray-shaped members. Two interlocking mechanisms are operable to reliably secure the tray members to one another when engaged together by sliding of the lower tray member into place along an underside of the upper tray member. The insert includes a rear wall portion disposed between upstanding rear walls of the tray members, and a height of the upper tray member is reduced at a front edge thereof to provide optimal viewing of the opposing rear wall portion of the insert. A seal positively positioned in a groove of the lower tray member provides a water tight seal between the tray members to protect the informational insert.
