There is disclosed herein a toaster (10) including: a housing (12); a pair of opposing food guards (24a, 24b) located within the housing (12) and defining a toasting cavity (25a, 25b) for receiving foodstuff to be toasted; a pair of heating elements (28) located within the housing (12), each heating element (28) being located on a respective side of the pair of food guards (24a, 24b), wherein each food guard (24a, 24b) is spaced from the corresponding heating element (28) by a clearance (81); and wherein each food guard (24a, 24b) has an upwardly-extending portion (75c, 75d) that extends upwardly to a portion (75a, 75b) that extends transversely from the upwardly-extending portion so as to extend above the corresponding heating element (28), the transversely-extending portion (75a, 75b) of each food guard (24a, 24b) projecting away from the opposing food guard (24a, 24b).

Disclosed is a non-stick coating for an article, particularly for a baking pan or other household and utility item, comprises at least a base layer (G) burnt onto a surface (O) of the article and a covering layer (D) burnt above the base layer. The base layer and the covering layer each have a dry film thickness of 1 to 25 μm, wherein the base layer contains 10 to 100 wt.-%, related to the weight of the burnt base layer, of a thermoplastic resin having a temperature resistance exceeding 200° C., and wherein the covering layer contains a thermoplastic resin having a temperature resistance exceeding 200° C. and optionally a silicone resin. Both the base layer and also the covering layer are free of perfluorinated and polyfluorinated alkyl compounds. Due to the fact that the covering layer comprises a content of thermoplastic resin of at least 30 wt.-%, related to the weight of the burnt covering layer, and of at least 2.5 wt.-%, related to the weight of the burnt covering layer, of a silicone oil, novel fluorine-free non-stick coatings with good substrate adhesion and very good deep-drawing properties are obtained. In a process for applying the non-stick coating, the base layer to be formed is applied as a liquid varnish onto the surface of the article and subsequently dried at 250 to 440° C., subsequently the covering layer is applied as liquid varnish onto the predried base layer, and finally the layers are bonded to each other and to the surface of the article by means of heat treatment at 250 to 440° C.

The present invention relates to a method of treating a surface of a utensil as well as to a utensil having been treated by the method. A substrate is provided to form a component of the utensil. The substrate has a surface area to be treated. Through a shot peening process particles impact the substrate substantially evenly across the surface area, so as to dimple the substrate with depressions across the surface area, in order to reduce adhesion of matter on the treated surface area of the utensil.

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.

Provided are aqueous fluororesin coating compositions including a water-soluble polyamideimide resin, a polyetherimide, and a fluororesin. Also provided are coatings on substrates formed from the coating composition and coated substrates, the coatings being strongly adhered to the substrates and having excellent water vapor and corrosion resistance. The coatings are of utility for metal substrates, for example cookware such as a frying pans and rice cookers.

Provided is a method of producing a cooking vessel, including the following steps: forming a blank from a sheet of stainless steel; drawing of the blank to form a cap comprising an interior surface and an exterior surface, the interior surface comprising a flat base area surrounded by a side wall; hot stamping of a diffuser base onto the exterior surface of the cap; engraving of a grid pattern over at least one portion of the base area of the interior surface of the cap to form a network of ribs having top surfaces that extend above the valleys and side surfaces that are distinct from the bottom surfaces of the valleys, said side surfaces of the ribs connecting the top surfaces of the ribs to the bottom surfaces of the valleys, the side surfaces of the ribs forming ramps connecting the top surfaces of the ribs to the bottom surfaces of the valley; sanding of at least the engraved base area of the interior surface of the cap, to create roughness; applying a non-stick coating on at least the sanded, engraved base area; and brushing and/or polishing of at least the sanded, engraved and coated base area to reveal the stainless steel on the top surfaces of the ribs.

Provided is an aqueous amine-free coating composition including at least one aromatic polymer, wherein the aromatic polymer is in the form of powder having a d.sub.90 less than or equal to 20 μm and in that the aqueous coating composition further includes polar aprotic solvent at a content greater than 0% by weight and less than or equal to 25% by weight. Also provided is an aqueous amine-free non-stick coating composition including such an aqueous composition for a coating, and the respective methods for producing same. Further provided is a method for producing an item on one of the faces of a metal substrate, from at least one layer of the coating composition or one layer of the non-stick coating composition.

Provided is a cooking utensil having an excellent design. The cooking utensil includes a bottom and a side extending substantially upward from a perimeter of the bottom. The bottom includes a bottom laminate film on an inner surface thereof. The side includes a side laminate film that is different from the bottom laminate film on an inner surface thereof. The bottom laminate film and the side laminate film have different color tones.

An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include 15 to 50 wt % of phosphorus pentoxide (P.sub.2O.sub.5); 5 to 20 wt % of one or more of lithium oxide (Li.sub.2O), sodium oxide (Na.sub.2O), or potassium oxide (K.sub.2O); 1 to 5 wt % of one or more of sodium fluoride (NaF), calcium fluoride (CaF.sub.2), or aluminum fluoride (AlF.sub.3); 1 to 35 wt % of one or more of magnesium oxide (MgO), barium oxide (BaO), or calcium oxide (CaO); and 5 to 30 wt % of one or more of manganese dioxide (MnO.sub.2), molybdenum trioxide (MoO.sub.3), bismuth oxide (Bi.sub.2O.sub.3), or nickel oxide (NiO).
