Abstract:
The profile shape of the vessel body and of handle portion is formed from a single sheet of metal to create a flat by cutting, stamping or blanking. An opening is created in the handle portion to reduce heat propagation. The shape of the pan body is formed by spinning with the flat handle portion. The handle is formed by creating three-dimensional contours in the handle portion of the blank. The neck portion has a flat section adjacent the pan body followed by sections of different curvature. One section of the neck portion has a deeply curved cross-section. That neck portion transitions to the hand grip portion which has a reduced curvature, particularly toward the unattached end of the handle. The neck portion may have a “W” cross sectional shape. The handle grip portion may have a “U” shaped cross-section for comfort.
