A paperboard tray and a blank therefor is disclosed which is collapsible to form a carton. More specifically, the subject tray may be collapsed and sealed to hold a product and may then be subsequently opened and reformed into a tray for use in serving or cooking. A pair of handle flanges are provided defining carrying handles when the tray is opened and for structurally rigidifying the tray and preventing its inadvertent collapse.

A collapsible tray comprising: a generally rectangular bottom wall having a rectangular center panel and first and second rectangular bottom panels hingedly connected to opposed side edges of said center panel; first and second upstanding end panels hingedly connected to the side edges of said bottom panels opposed to the hinged connections to said center panel; first and second upstanding side panels hingedly connected to the remaining opposed side edges of said bottom wall, with the adjacent side edges of said end panels and said side panels being respectively hingedly connected to define a continuous side panel structure, each said side panel having a center section disposed co-extensive with and hingedly connected to the adjacent side edge of said center panel and with each said side panel further including first and second side sections hingedly connected to the opposed side edges of the associated center section and disposed co-extensive with and hingedly connected to the adjacent side edges of the first and second bottom panels, each said side section of said side panels including a diagonal fold line extending from the intersection between said side section and said center panel of said bottom wall; and a pair of handle flanges, respectively hingedly connected to the opposed side edges of said side panels, each said handle flange capable of being rotated at an angle relative to said side panel and extending away from the interior of said tray, said handle flanges thereby providing a means for carrying said tray and for rigidifying said tray, said tray being collapsible into an enclosed carton by upwardly folding said bottom panels of said bottom wall relative to said center panel thereof such that said bottom panels define side walls of said enclosed carton and said end panels cooperate to define a continuous top wall, and with each said side section being folded inwardly about said diagonal fold line such that said side sections and said center section of each said side panel overlap to define a triple ply end wall structure, whereby an enclosed carton is defined.
