Two substantially identical tray members cooperate to define an enclosed space for a pizza pie or the like, each having a circular base wall, a frusto-conical side wall and an annular flange. A rib and groove arrangement in the flanges allows the tray members to remain concentric while mutually rotating between one angulation wherein a locking arrangement is disengaged, and a second angulation in which the locking arrangement is engaged.

A tray member adapted for cooperation with a substantially identical tray member to define an enclosed space adapted to receive a pizza pie, comprising: a base wall portion having a center an a substantially circular circumference, a substantially frusto-conical side wall extending from said circumference to a substantially circular edge, the side wall being substantially concentric with said base wall, a flange extending outwardly from said edge to a flange periphery, said flange having a flange surface directed away from the base wall, groove means in said flange, the groove means being substantially concentric with said base wall and extending around a portion of said flange which is less than the entirety of the flange, protuberant means projecting from said flange at a location substantially opposed to that of said groove means, the protuberant means extending around a portion of the flange which is less than that occupied by said groove means, the protuberant means being substantially concentric with said base wall and adapted to be slidably received within the groove means on a substantially identical such tray member when the tray members are placed with said flange surfaces facing each other, and two locking tab means at substantially opposed locations around the flange, each locking tab means being adapted to interengage with a similar locking tab means on a substantially identical such tray member so that the two tray members may rotate with respect to each other between a first mutual angulation in which the locking tab means are engaged.
