Methods or processes of manufacturing specially adapted for cooking-vessels} - A47J 27/02: with enlarged heating surfaces - A47J: KITCHEN EQUIPMENT; COFFEE MILLS; SPICE MILLS; APPARATUS FOR MAKING BEVERAGES ## Abstract A vessel (1) for heating the contents thereof by means of an external heat source (8) comprises a non-horizontal side wall (2) and a heat transfer structure (6) attached to and in good thermal contact with, or formed integrally on, an outer surface of said side wall. ## Claims ### Claim 1 A vessel for heating contents thereof by means of an external heat source, the vessel comprising: a non-horizontal side wall terminating at a base of the vessel; and a heat transfer structure comprising a plurality of ribs or fins attached to and in good thermal contact with, or formed integrally on, an outer surface of said side wall, wherein the plurality of ribs or fins comprise a shape that tapers in a direction away from the side wall; wherein each rib or fin of the plurality of ribs or fins extends radially outward from the side wall, and comprises an upper end, a lower end, an upper outermost radial extent proximate to the upper end, a lower outermost radial extent proximate to the lower end, and a reduced outermost radial extent at a position between the upper end and the lower end, wherein for each rib or fin of the plurality of ribs or fins, each of the upper outermost radial extent and the lower outermost radial extent is greater than the reduced outermost radial extent; and wherein the plurality of ribs or fins extend along the side wall and extend in a continuous manner from the side wall to an underside of at least a portion of the base of the vessel. ### Claim 2 (depends on 1) A vessel as claimed in claim 1, configured for placement on a gas stove. ### Claim 3 (depends on 1) A vessel as claimed in claim 1, wherein the vessel is suitable for heating liquid and/or food contents. ### Claim 4 (depends on 1) A vessel as claimed in claim 1, wherein the base is substantially horizontal, and wherein the side wall is continuous around the vessel and extends upwardly from the base. ### Claim 5 (depends on 1) A vessel as claimed in claim 1, wherein the side wall comprises a circular cylinder shape. ### Claim 6 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins are provided on a portion of the side wall spaced at least 7 cm, or at least 10 cm, from a centroid of the underside of the vessel. ### Claim 7 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins are directly and/or permanently attached to the side wall. ### Claim 8 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins comprise strips. ### Claim 9 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins extend vertically. ### Claim 10 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins extend along an entire length of the side wall. ### Claim 11 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins are equally spaced around the side wall. ### Claim 12 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins comprise at least four ribs or fins. ### Claim 13 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins project from the side wall by at least 5% of a diameter of the vessel. ### Claim 14 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins are formed directly on the side wall of the vessel. ### Claim 15 (depends on 1) A vessel as claimed in claim 1, wherein the plurality of ribs or fins extending in a continuous manner from the side wall to the underside of the at least a portion of the base of the vessel are arranged to permit the vessel to stand flat on a flat surface. ### Claim 16 A vessel for heating contents thereof by means of an external heat source, the vessel comprising: a non-horizontal side wall terminating at a base of the vessel; and a plurality of ribs or fins attached to and in good thermal contact with, or formed integrally on, an outer surface of said side wall; wherein each rib or fin of the plurality of ribs or fins extends radially outward from the side wall, each rib or fin comprises an upper end and a lower end, and each rib or fin comprises an outermost radial extent proximate to the lower end and an outermost radial extent proximate to the upper end that are each greater than an outermost radial extent at a position between the lower and upper ends; and wherein each rib or fin extends along the side wall and extends in a continuous manner from the side wall to an underside of at least a portion of the base of the vessel. ### Claim 17 (depends on 16) A vessel as claimed in claim 16, wherein the plurality of ribs or fins extend vertically along the side wall. ### Claim 18 A vessel for heating contents thereof by means of an external heat source, the vessel comprising: a non-horizontal side wall; and a plurality of ribs or fins attached to and in good thermal contact with, or formed integrally on, an outer surface of said side wall; wherein each rib or fin of the plurality of ribs or fins extends radially outward from the side wall, each rib or fin comprises an upper end and a lower end, and each rib or fin comprises an outermost radial extent proximate to the lower end and an outermost radial extent proximate to the upper end that are each greater than an outermost radial extent at a position between the lower and upper ends. ### Claim 19 (depends on 18) A vessel as claimed in claim 18, wherein the plurality of ribs or fins extend vertically along said side wall.
