CA 2317827

A lid 10 for a pressure cooker has two radially slidable jaws 12 and 13 with upstanding lips 15 and 16, respectively. A locking plate 18 can slide transversely outwards from the position shown so that the lips ride along limbs of apertures 20 and are thereafter held, to prevent radial movement, by the plate 18. The plate 18 is held in its transverse outward position by a plunger (not shown) of a locking valve that is engaged in an aperture 23 in the plate 18. The plunger is released to fall from an uplifted locking position when pressure in the cooker falls below a predetermined level and to enable the plunger to become slidable along the aperture 23. This allows the plate to move and unlock the jaws 12 and 13 and so that the lid 10 can be removed.
