    [0001] TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical field of stainless steel cooking utensils. The present invention relates more particularly to cooking utensils obtained by stamping from a stainless steel sheet, as well as to their method of production. The present invention relates in particular to cookware intended to be arranged on a firebox, such as for example stoves or pans. The present invention also relates to cooking lids and removable tanks of electric cooking appliances. It is known to make stainless steel cooking utensils by stamping. During stamping, defects may appear on the surface of the utensil, especially on the outer surface. The phenomenon of roping is mainly found in ferritic stainless steels and mainly concerns the side wall of the utensil. The phenomenon of orange peel can occur mainly on the rounding connecting the bottom to the side wall of the utensil, and to a lesser extent on the bottom. To hide the aforementioned defects, it is necessary to provide a pronounced polishing of the outer face. GB 2 076 708 proposes to produce a culinary article having a textured outer surface. However, this outer face is made of aluminum or copper. This document contemplates the use of stainless steel to make the inside of a culinary article made of colaminate. Document KR 20100100513 proposes to produce a stainless steel culinary article having a textured face. However, this textured face is a coated inner face. An object of the present invention is to provide a method of manufacturing a cooking utensil having a pressed stainless steel outer surface, which makes it possible to simplify the polishing operations of said outer face, without degrading the external appearance of the cooking utensil. Another object of the present invention is to provide a cooking utensil having a stamped stainless steel outer surface which is less sensitive to scratches.
    [0002] These objects are achieved with a process for obtaining a cooking utensil, comprising the following steps: - Realization or supply of a sidewall from a textured stainless steel sheet having at least one textured face, - Stamping the flank to form a cap having an inner face and an outer face, the outer face having raised portions corresponding to the textured face of the flank, - Optionally, partial overlap of the outer face of the cap, - Mechanical finishing treatment of the free surface of the outer face of the cap, to reveal the stainless steel on the raised portions of the free surface of the outer face of the cap. The use of the textured face of a stainless steel sheet to make the outer face of a cookware cap makes it possible to mask the defects that appear during manufacture, particularly during stamping. A satisfactory surface appearance of the free surface of the outer face can be achieved with a mechanical finishing treatment, whereas with a smooth outer face a pre-polishing of the stainless steel is required. According to one embodiment, the mechanical finish treatment comprises a finishing type finishing polishing, without pre-polishing phase using abrasive particles. Masking defects makes it unnecessary to pre-polish the stainless steel, which helps to shorten the manufacturing time and limit polishing residues and effluents. According to one embodiment for obtaining a colored outer surface, the method consists in using a textured stainless steel sheet having on the textured side a surface oxide layer providing interferential coloring, and performing the mechanical finishing treatment. to remove the surface oxide layer on the raised portions of the free surface of the outer face of the cap, so as to reveal the stainless steel. These provisions make it possible to protect the colored parts of the free surface of the outer face of the cap.
    [0003] According to another embodiment, the method consists in producing an outer coating on the free surface of the outer face of the cap, and the mechanical finishing treatment comprises a brushing to remove the outer coating on the raised parts of the free surface. of the outer face of the cap. These provisions also protect the coated parts of the free surface of the outer face of the cap. According to an embodiment adapted to the production of cooking utensils designed to rest on a heating plate, the method consists in making a hot-stamping assembly of the cap with an aluminum thermal diffusion plate partially covering the outer face of the cap, and perform the finishing mechanical treatment after assembly by hot stamping. Advantageously, the method consists in producing a hot-stamping assembly of the cap with an aluminum thermal diffusion plate partially covering the outer face of the cap and with a stainless steel bottom plate covering the thermal diffusion plate, and perform mechanical finishing treatment after hot stamping. Advantageously then, to obtain a cooking utensil compatible with induction heating, the bottom plate is made of ferritic stainless steel.
    [0004] Advantageously, the process consists in producing an inner liner on the inner face of the cap before the mechanical finishing treatment. Advantageously then, the method consists in producing the inner lining on the inner face of the cap after assembly by heat-striking the cap with the diffusion plate. According to an advantageous arrangement, the method consists in using a circular flank forming a disk. Other geometries can however be envisaged.
    [0005] These objects are also achieved with a cooking utensil having a stainless steel cap having an inner face and an outer face, because the outer face of the cap has a textured free surface. This arrangement makes it possible to mask the mechanical defects appearing during the life of the cooking utensil, in particular scratches made with a metal utensil such as for example a spatula, or with an abrasive material such as a stamp type Scotch-BriteTM. Advantageously, the outer face of the cap has etching depths of between 20 and 100 μm.
    [0006] According to an embodiment adapted to the production of cooking utensils designed to rest on a heating plate, an aluminum heat diffusion plate partially covers the outer face of the cap. This arrangement allows a better distribution of heat. Advantageously then, a bottom plate of stainless steel covers the thermal diffusion plate. Advantageously then, to obtain a cooking utensil compatible with induction heating, the bottom plate is made of ferritic stainless steel.
    [0007] Advantageously, the inner face of the cap has an inner liner. If the inner face of the cap is not coated, an emery finishing is preferably performed. Advantageously, the free surface of the outer face of the cap has polished prominent portions of stainless steel and recessed portions, if desired coated and / or colored. According to various embodiments, the recessed portions may in particular have one of the following surfaces: PTFE coating, ceramic coating, lacquer, superficial oxide layer providing interferential coloration. Advantageously, the cap has a circular geometry. According to one embodiment, the cooking utensil comprises at least one handle mounted on the cap. The utensil according to at least one of the above-mentioned characteristics can be obtained by the aforementioned method. The invention will be better understood from the study of several embodiments, taken without limitation, illustrated in the accompanying figures, in which: FIGS. 1 to 5 are five exemplary embodiments of stainless steel sheets used in the FIG. 6 is a diagrammatic sectional view of an exemplary embodiment of a cooking utensil according to the invention, comprising a textured stainless steel cap with an attached diffuser base. FIG. 7 is a partial view of an alternative embodiment of the cooking utensil illustrated in FIG. 6, comprising a handle, FIG. 8 is a schematic sectional view of another embodiment of a utensil. according to the invention, comprising a textured stainless steel cap and a handle, - Figure 9 is a perspective view of an alternative embodiment of a cooking utensil according to the invention, comprising a The colored textured stainless steel cap, FIG. 9a being an enlarged view of a portion of FIG. 9, FIG. 10 is a perspective view of another alternative embodiment of a cooking utensil according to the invention. comprising a post-polished PTFE coated textured stainless steel cap, FIG. 10a being an enlarged view of a portion of FIG. 10. FIGS. 1-5 illustrate various embodiments of textured stainless steel sheet. The outer surface of these sheets is not simply smooth or polished, but has a raised pattern, namely a texture. This pattern can be repetitive. The relief pattern then has a regular periodic pattern. The raised pattern may have clearly visible axes of symmetry, in particular in the following forms: embossed (Figure 1); in strips (Figure 2); checkerboard (Figure 3); woven, or canvas (Figure 4). However, the relief pattern is not necessarily repetitive. The raised pattern may appear more irregular, as shown in particular in Figure 5. The raw material used is a stainless steel sheet having undergone an additional etching operation during rolling.
    [0008] The stainless steel may be austenitic stainless steel (for example type 304 stainless steel) or ferritic stainless steel (for example type 430, 441, or 436 stainless steel). The sheets are mechanically etched by printing from a roll of rolling mill having a pattern in relief.
    [0009] Two types of engraving finishes exist: engraving on one side (the other face remains smooth) or on both sides. In the case of a cooking utensil-type application, an engraving on one side is preferably used. The etched face is preferably a convex face forming an outer portion of the cooking utensil.
    [0010] In the case of an engraving on one side, however, the engraved patterns are superimposed on the smooth face. To prevent the inner face of the cooking utensil from having a rough appearance of the "orange peel" type, the use of engraving textures having a periodic pattern is preferred.
    [0011] Moreover, the greater the depth of the etched pattern will be important, the more the overprint on the smooth face will be marked. Preferably, etching depths of between 20 and 100 μm are used. The etching is performed during rolling with special cylinders. The rolling engraving operation preserves the properties of the passive layer of stainless steel. The etching is followed by a bright annealing operation. This operation can restore the ductility of the material for good drawability, preserve its brilliance and provide an optimal passive layer to resist corrosion. These operations make it possible to obtain a homogeneous and reproducible surface finish for different shades and dimensions. In the case of a ferritic grade, the texture partially masks the rope phenomenon occurring on the side wall of the embossed food utensil. The polishing operation is thus facilitated. All the operations for obtaining a stainless steel cooking utensil are then carried out: cutting a sidewall in the stainless steel sheet, stamping the sidewall to form a cap 2, advantageously struck with a diffuser base 10, possibly internal and / or external coating and then polishing the free surface of the outer face of the cap 2.
    [0012] If the largest dimension of the sidewall is smaller than the circumference of the engraved rolling cylinder having a non-periodic pattern, or less than the period of the pattern of the engraved rolling roll, in the case of a periodic pattern, the texture of the face textured cap will appear aperiodic.
    [0013] The diffuser base 10 usually comprises a heat diffusion plate 11 made of aluminum interposed between a bottom plate 12 of stainless steel and the cap 2 stamped of the cooking utensil, made of etched stainless steel. The bottom plate 12 may in particular be made of ferritic stainless steel, to obtain a cooking utensil compatible with induction heating. If desired, the bottom plate 12 may form a cup. The cooking utensil illustrated in Figure 6 comprises a cap 2 of stainless steel having an inner face 3 and an outer face 4. The cap 2 has a circular geometry. The outer face 4 of the cap 2 has a textured free surface 5. The heat diffusion plate 11 made of aluminum partially covers the outer face 4 of the cap 2, leaving exposed the free surface 5. Different forms of cooking utensils can be obtained, in particular a stove, such as for example shown in FIG. or a saucepan, a frying pan, a wok, a tank of an electric cooking appliance, but also a lid, such as for example shown in FIG. 8. As shown in FIGS. 7 and 8, the cooking utensil cooking may comprise at least one handle 13 mounted on the cap 2. The handle 13 may in particular be fixed on a stud 14 welded to the cap 2.
    [0014] The thicknesses of stainless steel sheets used are usually between 0.5 and 0.8 mm. A typical thickness is 0.6 mm. The interior of the stainless steel cookware may have a cooking surface or a surface exposed to cooking, either uncoated or coated, for example with a PTFE coating, or with a ceramic coating developed by ground -gel. The inner face 3 of the cap 2 then has an inner liner 6. The method of manufacturing a cooking utensil according to the invention may comprise the following steps: - Cutting of the engraved stainless steel sheet, usually in the form of disc, to form a flank, or selection of an already cut flank, stamping the flank, generally made without protective film of the texture, to form the cap 2. When a protector of the texture is used, this protective film is removed after this stamping operation. The texturing makes it possible to mask certain defects appearing during stamping, such as in particular the rope, observed in the lateral wall for ferritic stainless steel stamped sheets, or the orange peel, observed in the rounding connecting the bottom to the side wall of the stamped sheet. - Optionally, hot stamping of the diffuser base 10. The striking operation is performed on the cap 2 without prior mechanical surface treatment. It causes yellowing of the cap 2 on the bottom of the side wall. The diffuser base 10 guarantees homogeneity of temperature of the cooking surface during the temperature rise of the cooking utensil. Optionally, making an inner liner 6 on the inner face 3 of the cap 2 forming the cooking surface. A coating phase of an inner coating 6 of PTFE or ceramic type may in particular be provided. A surface preparation intended to promote the attachment of the lining 6, for example sandblasting, may be provided before the coating phase. The firing of these coatings (typically 430 ° C. for 20 minutes for the PTFE coating, 250 ° C. for 15 minutes for the sol-gel ceramic coating) leads to a yellowing of the free surface 5 of the outer face 4 of the coating. cap 2. Polishing of the free surface 5 of the outer face 4 of the cap 2. This polishing is necessary to suppress the yellowing due to the growth of the oxide layer appeared locally during the striking of the diffuser base 10, and on the entire surface of the cap 2 during the baking of the inner liner 6. A suitable choice of parameters allows a polishing to remove the yellowing without degrading the pattern in relief of the free surface 5 of the outer face 4 of the cap 2. The use of textured stainless steel reduces the polishing ranges achieved. Indeed, the main defects appearing during stamping being masked by the texture, a pre-polishing phase aimed at reducing the roughness of the free surface 5 of the outer face 4 of the cap 2 by the action of abrasive particles is useless before considering a brightening phase. The brightening phase is polishing to achieve very bright surfaces, usually using discs made of leather, felt or fabrics, covered with polishing products. The brightening phase is therefore sufficient for the finishing of the bakeware having a textured outer surface. The cookware thus obtained has an original exterior finish less sensitive to scratching. In addition, the obtaining operations carried out from the stainless steel sheet can be simplified, or even accelerated, because of more limited polishing operations. The essential steps in the method of obtaining a cooking utensil according to the invention are as follows: - Realization or supply of a sidewall from a textured stainless steel sheet having at least one textured face 1, - Embossing the sidewall to form a cap 2 having an inner face 3 and an outer face 4, the outer face 4 having portions in relief corresponding to the textured face 1 of the sidewall, - optionally, partial overlap of the outer face of the cap 2 , so that the outer face 4 of the cap 2 has a free surface 5, - mechanical finishing treatment of the free surface of the outer face 4 of the cap 2, to reveal the stainless steel on the raised portions of the free surface of the outer face 4 of the cap 2. The mechanical finishing treatment used with a textured stainless steel flank comprises a finishing polishing type brightening, san Pre-polishing phase using abrasive particles. Alternatively, it is possible to consider the possibility of using as raw material a textured colored stainless steel sheet. The austenitic stainless steels can indeed be colored by the INCO process: - Immersion in a CrO 3 + H 2 SO 4 bath: During this phase, an oxide layer grows on the surface of the stainless steel and gives an interferential coloration on the surface stainless steel. The color obtained depends directly on the thickness of the oxide layer, and therefore the treatment time. - Cathodic hardening to make the layer mechanically resistant. One of the difficulties remains the fragility of the colored film. The combination of texturing and coloring overcomes this disadvantage. Indeed, by slightly polishing the end of the patterns, the colored portion of the stainless steel remains in the recessed portions and is therefore less likely to be damaged. The method then involves using a textured stainless steel sheet having a surface oxide layer on the textured side 1 providing interferential staining, and performing the mechanical finishing treatment to remove the surface oxide layer on the portions in relief of the free surface 5 of the outer face 4 of the cap 2, so as to reveal the stainless steel. Finishing-type finishing polishing is sufficient to perform such an operation. The cookware illustrated in FIG. 9 is a tub obtained from the textured stainless steel sheet shown in FIG. 3, having a regular checkered pattern. This pattern is slightly deformed by the stamping operation, as best seen in Figure 9a. The free surface 5 of the outer face 4 of the cap 2 has prominent polished portions 8 of stainless steel and colored hollow portions 9. The colored hollow portions 9 have a surface oxide layer providing interferential staining. The outer face 4 thus has a partial outer skin 7. The smallest surface dimension, or width, of the protruding portions 8 and the recessed portions 9 is preferably between 0.5 mm and 3 mm, and has an average value of the order of 2 mm in the embodiment illustrated in FIGS. Figures 9 and 9a. The inner face 3 is preferably free of inner liner, the firing of a coating modifying the thickness of the surface oxide layer, which contributes to degrade the coloring. If desired, the cap 2 can receive a diffuser bottom (not visible in Figure 9). Alternatively also, after the production of a cap 2 of textured stainless steel, the outer face 4 of the cap 2 may be coated with an outer coating 7 such as for example a PTFE coating or a ceramic coating, or a lacquer. An outer coating 7 of PTFE type improves the ease of cleaning the free surface 5 of the outer face 4 of the cap 2. The outer coating 7 may be black or colored. After cooking or drying of the outer coating 7, a post-polishing operation makes it possible to reveal the edges of the stainless steel, making it possible to carry out decoration effects on the free surface 5 of the outer face 4 of a cooking utensil. stainless steel. Such outer faces 4 have a better scratch resistance than smooth outer surfaces coated or not. The method then consists in producing the outer coating 7 on the free surface 5 of the outer face 4 of the cap 2, where appropriate after hot-stamping the cap 2 with the diffuser base 10, and producing a mechanical finishing treatment comprising a brushing to remove the outer coating 7 on the raised parts of the free surface 5 of the outer face 4 of the cap 2, so as to reveal the stainless steel.
    [0015] The cooking utensil illustrated in FIG. 10 is a vessel having a diffuser base 10, obtained from the textured stainless steel sheet shown in FIG. 5, having an irregular, or aperiodic, pattern. This better visible pattern in Figure 10a is also slightly deformed by the stamping operation. The free surface 5 of the outer face 4 of the cap 2 also comprises 8 polished stainless steel prominent parts and coated hollow portions 9. The hollow portions 9 coated can then have in particular a PTFE coating, a ceramic coating, or a lacquer. The outer face 4 thus has a partial outer skin 7. If desired, the outer coating 7 may be colored. The smallest surface dimension, or width, of the protruding parts 8 and the hollow parts 9 is preferably between 0.5 mm and 3 mm, and has an average value of about 0.8 mm in the illustrated embodiment. in Figures 10 and 10a. The largest surface dimension, or length, not necessarily rectilinear, prominent portions 8 and recessed portions 9 may be greater than 3 mm. The inner face 3 may or may not include an inner liner. Usually, the method consists of using a circular flank forming a disk. However, the flank does not necessarily have a circular geometry. An elliptical geometry may be considered in particular for making a fish frying pan, or a lid corresponding to such a cooking utensil. In a preferred manner, in order to produce cooking utensils of the culinary article type having a good heat distribution, the method consists in making a hot-stamping assembly of the cap 2 with a heat diffusion plate 11 made of aluminum partially covering the outer face. 4 of the cap 2, and to perform the mechanical finishing treatment on the free surface 5 of the outer face 4 of the cap 2 after assembly by hot stamping of the cap 2 with the diffuser base 10 comprising the diffusion plate thermal 11.
    [0016] If desired, a hot-stamping assembly of the cap 2 with an aluminum heat diffusion plate 11 partially covering the outer face 4 of the cap 2 and with a bottom plate 12 made of stainless steel covering the thermal diffusion plate 11 may to be achieved, the mechanical finishing treatment on the free surface 5 of the outer face 4 of the cap 2 being performed after assembly by hot stamping the cap 2 with the diffuser base 10 comprising the thermal diffusion plate 11 and the Background plate 12. Advantageously, to improve the properties of the inner face 3 of the cap 2, the method may consist in producing an inner liner 6 on the inner face 3 of the cap 2 before the mechanical finishing treatment. In a preferred manner, the process consists in producing the inner lining 6 on the inner face 3 of the cap 2 after heat striking assembly of the cap 2 with the diffuser base 10 comprising the thermal diffusion plate 11 and, if desired the bottom plate 12.
    [0017] If the inner face 3 of the cap 2 is not coated, an emery finishing is preferably carried out. The texturing of the outer face 4 hides the defects that can appear either during the production of the cooking utensil (stamping defects), or during the use of the cooking utensil (scratches). Alternatively, the recessed portions 9 are not necessarily colored and / or coated. The present invention is in no way limited to the described exemplary embodiments and their variants, but encompasses many modifications within the scope of the claims.
