Multi-purpose baking utensil

Claim 1

A baking utensil selectively adaptable to contain batter for producing baked goods of a plurality of sizes and shapes, said utensil comprising: (a) a pan portion including a substantially rectangular bottom wall with two side walls extending integrally in the same direction from said bottom wall along opposite edges thereof, for equal distances to provide substantially parallel top edges of said side walls; (b) each of said side walls having a plurality of openings therethrough at spaced locations to provide pairs of openings directly opposite one another along said side walls adjacent said top edges thereof; (c) at least two end members each having substantially parallel top and bottom edges and opposite side edges each having an outwardly extending protrusion for releasable insertion in one of said opposite pairs of openings; (d) said bottom wall being curved upwardly to provide a convex surface in the direction of said side edges, and being of resiliently flexible material to permit urging said convex surface toward a planar configuration; and the relative sizes and shapes of said pan portion and said end members being such that when said protrusions on said side members are engaged in one of said opposite pairs of openings, said side edges are tightly engaged with said side walls and said bottom edge is tightly engaged with said bottom wall and flexes the latter to move said convex surface toward said planar configuration, whereby said end members form a batter-tight seal with said side and bottom walls.
