Abstract

Abstract A pizza pan having a substantially flat bottom surface surrounded by an arcuate or concave peripheral wall which terminates, at its outer edge, in a tubular element surrounding the entire outer periphery of the pan. A plurality of relatively small apertures are provided on the bottom of the pan and are selectively spaced thereon to provide a sufficient flow of heat to the central portion of the underside of the crust for an efficient baking thereof. A sufficiently great solid area is provided around the perforated area for supporting the outer edges of the pizza in a manner whereby the transfer of heat thereto is reduced with respect to the heat transfer at the perforate area to assure an even baking of the entire pizza.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 79 words
A pizza pan comprising a substantially flat bottom, a large radius, smooth peripheral wall conterminous with the bottom as a uniform uninterrupted surface, the wall extending upwardly and outwardly therefrom, and a plurality of spaced relatively small apertures provided in the bottom and contained within a central area smaller than the diameter of the bottom leaving a border of no apertures for the even distribution of heat to the central underside of the pizza during a pizza baking operation.
Claim 2
Dependent Claim 79 words
A pizza pan comprising a substantially flat bottom, a large radius, smooth peripheral wall conterminous with the bottom as a uniform uninterrupted surface, the wall extending upwardly and outwardly therefrom, and a plurality of spaced relatively small apertures provided in the bottom and contained within a central area smaller than the diameter of the bottom leaving a border of no apertures for the even distribution of heat to the central underside of the pizza during a pizza baking operation.
Claim 3
Dependent Claim 56 words
A pizza pan as set forth in claim 1 wherein handle means is provided around the outer rim of the peripheral wall for facilitating manipulation of the pan, the handle formed of a smaller diameter tubular configuration of a reverse curve to that of the peripheral wall yet as a smooth continuation of the peripheral wall.
Claim 4
Dependent Claim 18 words
A pizza pan as set forth in claim 1 wherein the apertures are each approximately 1/8" in diameter.
Claim 5
Dependent Claim 19 words
A pizza pan as set forth in claim 3 wherein the adjacent apertures are spaced on approximately 1/4" centerlines.
Claim 6
Dependent Claim 21 words
A pizza pan as set forth in claim 1 wherein the apertures are symmetrically spaced about the center of the bottom.
