ABSTRACT:
A chill-retention food service tray, capable of keeping its contents chilled for an extended time (e.g., several hours) in a warm environment, comprises a bottom tray member including a bottom panel having an upwardly projecting peripheral rim wall and a plurality of upwardly projecting stiffening ribs onto which a top tray member fits; the top tray member includes a support panel at the upper level of the reinforcing ribs and a peripheral rim wall engaging and adhesively secured to the bottom rim wall, as well as a closed configuration hollow wall defining a cup for a dip, sauce, or the like. The two tray members conjointly define a chamber filled with a various chilling gel; the gel has a high heat of fusion. A plurality of removable divider members may divide the top panel support surface, around the cup, into a series of storage compartments.
