Definitions
- the present invention relates to a culinary article comprising a non-stick coating deposited on a metal support, such as aluminum or aluminum alloy.
- the non-stick coatings commonly used to coat cookware are made from fluorocarbon resin, such as polytetrafluoroethylene (PTFE). If they are known for their non-stick properties as well as for their chemical and thermal resistance, PTFE-based coatings have the disadvantage of being particularly sensitive to scratching, in particular in the zone corresponding to the stressed surface. of the cookware. As a result, there is generally an early wear of cookware with this type of coating.
- This frame is formed of oblong elements arranged in a network, the composition of which comprises PTFE and from 5 to 20% by weight, preferably from 10 to 15% by weight, of fillers, in particular of metallic or mineral powder.
- the frame is then covered with a final layer of pure or lightly loaded PTFE, which completely drowns the frame.
- the surface in contact with food is consequently flat and therefore does not include deflection zones making it possible to effectively deflect the forces generated by metallic objects.
- Such a coating still has a certain sensitivity to scratching. In addition, it consumes a significant amount of charged material intended to form the reinforcement.
- document EP 0 580 557 proposes a non-stick coating comprising a layer of non-stick material which has a discontinuous and non-constant thickness.
- a discontinuous layer is applied to a first continuous layer of constant thickness over the entire surface of the support.
- This discontinuous layer is deposited at least on the central part of the bottom of the culinary article in a pattern which may be irregular or regular, in the form of a network, of dots or of graphic elements.
- the last layer of the coating is formed by the discontinuous layer which in a way creates "relief" zones.
- a solution to the problem posed is a culinary article formed by a metallic support and a non-stick coating deposited at least on the surface of the metallic support constituting the interior of the culinary article, the non-stick coating comprising at least two layers based on fluorocarbon resin, one of the at least two layers, which covers at least the stressing surface of the interior of the culinary article, being a discontinuous layer forming patterns.
- any cross section of the culinary article, at least at the level of its stressing surface exhibits regular interruptions in the plane of the discontinuous layer and each pattern presents, in top view of the interior of the cookware, an area of at least 1 mm 2 .
- the discontinuous layer therefore has patterns arranged in such a way that deflection zones limit the action of the forces generated by metallic or aggressive objects, without creating marked "relief” zones.
- the composition of the discontinuous layer formed of the patterns comprises at least one fluorocarbon resin as well as fillers.
- the presence of fillers in the composition of the patterns makes it possible to reinforce the resistance of the entire discontinuous layer and, consequently, to reinforce the overall resistance of the non-stick coating of the culinary article.
- the fillers contain pigments, it is advantageously possible to produce a culinary article in which the discontinuous layer forms a decoration which becomes visible through the non-stick coating, in the case where the layers of the non-stick coating located at the - above the discontinuous layer are transparent.
- FIG. 3 represents an enlarged schematic view in cross-section of another embodiment of a culinary article in accordance with the invention.
- the elements common to the different figures are identified by identical references.
- FIG. 1 there is shown a schematic view from above of a culinary article 1.
- This culinary article 1 comprises a central zone la, which corresponds to the stressing surface of the culinary article 1, which is that suitable for receiving and to be in contact with food and therefore with metallic objects, and which corresponds practically in general to the bottom of the culinary article 1.
- this stressing surface la could be larger than the bottom surface or on the contrary more reduced.
- a peripheral crown 1b corresponds to the edge of the culinary article 1 and surrounds said biasing surface 1a.
- the cookware 1 is formed of a metal support 2 and of a non-stick coating 3 deposited on the metal support 2.
- the metal support 2 is commonly made of aluminum, aluminum alloy, stainless steel or titanium.
- the non-stick coating 3 comprises at least two layers based on fluorocarbon resin, one of the at least two layers, covering at least the stressing surface 1a of the interior of the culinary article 1, being a discontinuous layer 5 forming patterns 6, 6 '.
- the non-stick coating 3 comprises a first continuous layer 4 of constant thickness, covering the entire interior surface ld of the metal support 2 and on which the discontinuous layer 5 is deposited on at least the area of the stressing surface la, along a plane P 3 parallel to the plane of the bottom P 2 , and the patterns 6, 6 'of which are separated by interruptions 9 in the material constituting the discontinuous layer 5.
- these two layers 4 and 5 can be reversed, the discontinuous layer 5 can then be located directly on the metal support 2 and, in any event, under the first layer
- the non-stick coating 3 is such that any cross section II-II, that is to say perpendicular to the plane P 2 defined by the bottom surface of the article 1, that this cross section is straight , that is to say formed of a single line segment and therefore not able to be constituted by a broken line, or that it is curved, has regular interruptions 9 in the plane P 3 higher and parallel to P 2 of the discontinuous layer 5, resulting on the one hand in a non-constant thickness of the non-stick coating 3 and on the other hand by a "decoration" comprising no rectilinear, curved, parallel or intersecting line with other lines.
- each pattern 6, 6 ' has, in top view of the interior of the culinary article 1, an area of at least 1 mm 2 .
- Such a minimum surface requirement makes it possible to create deflection zones capable of repelling the action of the forces generated by metallic objects.
- This minimum surface value is also suitable for industrial use.
- the surface of each pattern 6, 6 ′ is between 1 and 10 mm 2 .
- the proportion of surface covered by the "decoration" consisting of all of the patterns 6, 6 ' is greater than 15% of the total surface area applied to of the culinary article 1. More preferably , this proportion of surface covered by all of the patterns 6, 6 ′ is between 15 and 40% of the central zone forming it the total stressed surface of the culinary article 1.
- the patterns 6, 6 ' can be applied by any conventional means commonly used for the application of non-stick coatings based on fluorocarbon resin.
- the discontinuous layer 5 formed and constituting the patterns 6, 6 ′ is preferably applied by screen printing, in particular when the stamping operation is carried out after formation of the non-stick coating 3 on the 2-plane metal support.
- a method of application by pad printing is preferably envisaged.
- the composition of the discontinuous layer 5 constituting the patterns 6, 6 ′ comprises at least one fluorocarbon resin.
- the fluorocarbon resins suitable for the composition of the first layer 4 and of the discontinuous layer 5 are in particular described in document US 5,536,583.
- composition of the discontinuous layer 5 forming the patterns 6, 6 'further comprises pigments, aimed at imparting a color to the said patterns 6, 6'.
- pigments chosen from smoke black, titanium oxide Ti0 2 , mica flakes or silica flakes, said flakes being covered with oxides metal.
- thermochromic pigments and in particular iron oxide Fe 2 0 3 and / or perylene red, described in document WO 00/22395.
- the weight proportion of the pigments is determined as a function of the ability to cover said pigments. This weight proportion is commonly between 0.5 to 15% of the composition of the discontinuous layer 5 forming the patterns 6, 6 '. This weight proportion can be reduced to be between 0.5 and 7.5% of the composition of the discontinuous layer 5, in particular when pigments in the form of flakes are used, and / or when a application by screen printing of this discontinuous layer 5.
- a non-stick coating 7 is shown formed of three layers, the first layer 4 and the discontinuous layer 5 being similar to those shown in FIG. 2.
- the discontinuous layer 5 is covered by at least one finishing layer 8, also based on fluorocarbon resin as described above.
- the patterns 6, 6 ′ of the discontinuous layer 5 and the finishing layer 8 is transparent, the patterns
