Abstract
A cooking pan having an inner shell and an outer shell between which is an oil filled cavity containing a heating element the inner shell being secured to the outer shell by a rolled beaded edge formed in such a manner that the free edges of the respective inner shell and outer shell are not in contact with one another because the outer margin of the inner shell has been pre-beaded, the outer margin of the outer shell has been folded, and the relationship between the two is such that the folded portion is spaced slightly from the pre-beaded portion. The oil filling hole is provided with a circumferential seat against which an O-ring is urged by a cup-shaped plug for the hole backed by a spring and spring retainer held in position by a handle bracket provided with a spring retainer backing plate so that the oil filling hole plug functions also as a relief valve which is completely concealed beneath the handle.
