A nonstick utensil and its method of manufacturing are presented. The nonstick utensil includes a utensil substrate and a nonstick layer covering an inner surface of the utensil substrate. The material of the nonstick layer includes black titanium dioxide. An inner surface of a substrate of the nonstick utensil is covered with a material having black titanium dioxide applied by hot spraying, cold spraying or plasma spraying, so that a black titanium dioxide nonstick layer is formed. Compared to the prior art, instead of using a coating material, a nonstick layer having black titanium dioxide on a surface of a substrate is provided, having nonstick properties due to the low surface energy characteristic of black titanium dioxide.

An embodiment described in examples herein provides a leak resistant cooking pan. The leak resistant cooking pan includes a body and a lid. The lid includes a grooved rim sized to fit over a top edge of a sidewall of the body, wherein the grooved rim includes a heat resistant elastomer, and wherein the heat resistant elastomer forms a seal between the lid and the body.

A double-bottom enamel pan with good thermal conductivity, comprising a pan body and a double-bottom piece which is connected to an outer surface of a bottom of the pan body, wherein the double-bottom piece is provided with a plurality of annular bumps on one side matching with the pan body, the annular bumps are pressed into the pan body, and the double-bottom piece comprises at least one layer of enamel coating. The double-bottom enamel pan of the utility model has good thermal conductivity, so that heat and temperature distribution at the bottom of the pan body is uniform, which meets the user’s requirements of excellent service effect and long service life, and has a broad market application prospect.

A substrate coated with a non-stick fluoropolymer coating is provided, the coating having excellent abrasion and scratch resistance. The coating contains: i.) a continuous primer layer adhered to the substrate containing a polymer binder, a first fluoropolymer and first inorganic film hardner particles, ii.) a discontinuous midcoat layer containing aggregate particles adhered to the primer layer and distributed discontinuously across the surface of the primer layer so as to reveal exposed areas of the surface of the primer layer, wherein a portion of the aggregate particles are in clusters, and wherein the aggregate particles contain second fluoropolymer and second inorganic film hardner particles, and iii.) a topcoat layer containing a third fluoropolymer adhered to the midcoat layer and the exposed areas of the surface of the primer layer at points where there is no midcoat layer.

An article of cookware has an interior cooking surface that with raised linear or curvilinear bands with an outer layer of a first material that is one of ceramic or metallic in nature to provide cut and abrasion resistance. Valleys or grooves between the raised bands have an outer layer of a second material with low surface energy to facilitate food release and cleaning of debris. The bands are arranged to protect the second material from cutting and abrasion that would damage the second material. The bands aid in enhancing distribution of cooking oil to enhance searing and browning of foods.

An induction heating vessel, including an interior wall formed of a first material, an exterior wall formed of a second material, where the second material is different from the first material, and the second material is less magnetic than the first material, and a thermally insulating barrier between the interior wall and the exterior wall.

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.

The present invention relates to a culinary article (1) comprising a support (2) having a bottom wall (21) and a side wall (31) rising around the bottom wall (21), the bottom wall (21) having an inner face (211) for receiving food and an outer face (212) intended to be disposed close to a heat source, and the side wall (31) having an inner face (311) and an outer face (312) characterised in that the outer faces (212) and (312) are covered with at least one continuous primer layer comprising at least one fluorocarbon polymer, the coating of the outer face (212) comprises, arranged between or in its layers, at least one decoration representing at least 20% of the surface of the outer face (212), which decoration comprises at least one fluorocarbon polymer, at least one polymer resin and between 5 and 25% by weight of mineral fillers and/or polymer fillers, in the form of particles of size d50 less than 25 μm. The invention also relates to a method for making such an article.

An anti-stick titanium cookware and a method of manufacturing the same are provided. The anti-stick titanium cookware includes a titanium cookware body, a titanium cladding element, a heat-conducting element and an anti-stick layer. The titanium cookware body and the titanium cladding element are made of plate bodies, the titanium cladding element is welded on the lower surface of the titanium cookware body, and an interlayer space is formed between the titanium cladding element and the titanium cookware body. The heat-conducting element is accommodated in the interlayer space and contacts the lower surface of the titanium cookware body. The anti-stick layer is formed on the upper surface of the titanium cookware body. The heat-conducting element is fixed on the lower surface of the titanium cookware body through the titanium cladding element. The anti-stick layer is a titanium oxide film formed on the upper surface of the titanium cookware body.

A pie iron preparation system may be provided comprising a base substrate, a lid and one or more hinges. The base substrate may have a first elongate length-to-width dimensional ratio and may comprise a top surface that comprises one or more pie iron depressions formed therein. The lid may have the first elongate length-to-width dimensional ratio and may comprise a plurality of walls disposed at a perimeter edge thereof. The plurality of walls may surround a work surface disposed upon a first side of the lid. The one or more hinges may operably couple the base substrate to the lid.
