Abstract: A compact, lightweight pressure cooker which is particularly well-suited for backpacking and camping is disclosed. The pressure cooker assembly features two complementary mating pan sections which permit nestable, stacked engagement of one pan section within the other when disassembled. Each pan section has an annular, flanged rim which permits mutually superposed mating engagement when assembled. The pan sections are held together by clasp fasteners which are movable from a retracted, closed position of latching engagement with the assembled flanged rims to an open position in which the flanged rims are released, thereby permitting disengagement and separation of the pan sections. A curved handle is pivotally attached to each clasp and is movable from a retracted position in which the handle engages the clasp to an extended position in which both handles may be grasped and held together with one hand.
