A method for making a container includes forming a first cavity of a container by shaping an inner wall so that a first surface of the inner wall defines the first cavity; forming a second cavity of the container by shaping an outer wall so that a third surface of the outer wall surrounds a second surface of the inner wall such that together the third and second surfaces define the second cavity; and connecting the inner and outer walls together. The method then includes forming a hole through the outer wall to expose the second cavity to the outside ambient environment and then applying an enamel coating, while preventing the enamel coating from being deposited in the hole. After the enamel coating is applied, the method includes heating the container to glaze the enamel coating and fix the coating to the one or more surfaces.

A cooking vessel includes a vessel body having a partially coated, textured stainless steel inner surface having a plurality of ribs rising above recesses having bottoms covered with a non-stick coating. The ribs have uncoated tops and sides that are separate from the bottoms of the cavities. The sides connect the tops to the bottoms. The tops rise above the non-stick coating covering the bottoms. According to the invention, the non-stick coating rises over the sides from the bottoms towards the tops without exceeding the height of the tops, and the bottoms and the sides have a rough surface under the non-stick coating. Also included is a method for producing a cooking vessel.

The invention discloses a manufacturing method for a soup pot with partial concave-convex patterns on an outer surface thereof. The method comprises: preparing a plane blank for forming a pot body; screen-printing a layer of ink with preset patterns on a surface of the blank of the pot body; screen-printing a layer of ink with preset patterns on a bottom surface of the blank of the pot body; etching at positions where no patterns occurs on the surface of the blank of the pot body; stretching the blank of the pot body to form a soup pot, and flashing the edge of the pot body; and spraying a nonstick pan coating on the blank of the pot body, and polishing with abrasive paper at positions where the convex patterns occur and where no pattern occurs.

A cooking vessel, comprising a base, having an upper surface and a bottom surface, wherein the upper surface is configured to be in contact with food cooked inside the cooking vessel, sidewalls extending from the base, at the direction of the upper surface, said sidewalls have an internal surface configured to be in contact with food cooked inside the cooking vessel, wherein the base and the sidewalls are made of at least one metallic material sheets, wherein the base and the sidewall are connected by welding or folding, wherein the internal surface of the sidewalls and the upper surface of the base are coated by a coating layer configured to prevent degradation of the at least one metallic material sheets when heating the cooking vessel.

A process for manufacture of a profiled non-stick pan with a concave-convex pattern, which includes the following steps: preparing a flat blank for forming a pan body; screen printing a layer of ink with a predetermined pattern on a surface of the blank for a pan body, then drying and curing the ink; etching, by an etching process, the surface of the blank, on areas of the surface not covered by the ink, then cleaning and drying the blank, and retaining the ink; spraying non-stick pan coating on the blank, then baking the blank at high temperature, to enable the ink to automatically peel off at high temperature; pressing and stretching the blank to form a profiled pan body, then deburring and polishing on an edge of the pan body.
