In the related art, in the direction from the opening edge of the groove 11 to the bottom wall of the groove 11, because the side wall of the groove 11 extends straightly, a boundary edge can be formed between the side wall of the groove 11 and the bottom wall, when the paint is sprayed in the body 1, the flow rate of the paint is increased by the side wall of the groove 11 which extends straightly, on one hand, the residence time of part of the paint on the side wall of the groove 11 is short, the thickness of the coating 2 at the side wall of the groove 11 is small, and the adhesive force is low, on the other hand, the paint is easy to accumulate at the boundary edge, so that the coating 2 at the boundary edge is very thick, the accumulation causes less paint to further flow to the center of the bottom wall of the groove 11, the coating 2 at the bottom wall of the groove 11 is thin, so that the adhesive force between the coating 2 at the bottom wall of the body 1 and the body 1 is low, and after long-term use, the problem that the coating 2 at the bottom wall of the body falls off easily occurs.
And in this application, in the direction from the opening border of recess 11 to the diapire of recess 11, the lateral wall of recess 11 is the curved surface and extends, like this, can reduce the velocity of flow of coating at the lateral wall of recess 11 to a certain extent at least, helps improving the adhesion of coating on the lateral wall face of recess 11 on the one hand, guarantees coating cover and corresponding thickness on the lateral wall of recess 11, and on the other hand can reduce the coating layering phenomenon that brings because of the action of gravity, improves the non-stick effect.
Further, the entire inner wall surface of the groove 11 is a curved surface. Specifically, the entire inner wall surface of the groove 11 is a smoothly curved surface. For example, the side walls of the recess 11 and the bottom wall of the recess 11 are smoothly transitioned without forming a boundary edge therebetween. Through setting up the whole internal face with recess 11 to the curved surface, thereby recess 11's diapire and lateral wall do not have obvious boundary line, the internal face of recess 11 has been avoided there is the problem on boundary limit, when the spraying coating, can avoid the accumulation of coating in boundary limit department, be favorable to the levelling of coating, avoided because of coating piles up in boundary limit department and the boundary limit department coating 2 that leads to is thicker, recess 11 diapire coating 2 thinner problem, thereby be favorable to improving the cohesion of the internal face of coating 2 of recess 11 diapire and recess 11, and then improve container 100's life, and be favorable to improving the homogeneity of recess 11 bottom coating 2's thickness, can also avoid simultaneously because of the existence of the overheated point that coating 2 piles up and lead to, be favorable to improving the homogeneity of coating 2 heat conduction.

According to some embodiments of the present invention, coating 2 comprises a plurality of non-stick coatings arranged in a stack, any two adjacent non-stick coatings differing in composition. Generally, if the coating 2 only includes a non-stick coating, a single non-stick coating is set to be thicker in order to ensure non-stick performance, but the double effects of the curved side walls of the grooves 11, such as the retardation of paint flow and the thicker thickness of the single non-stick coating, are likely to cause paint delamination. According to the container 100 of the embodiment of the present invention, the non-stick coating is a multi-layer non-stick coating, and the multi-layer non-stick coating is configured such that each non-stick coating does not need to be very thick, so that the flow velocity of each non-stick coating on the sidewall of the groove 11 can be reduced in the actual processing process, which is helpful for improving the adhesion of the non-stick coating in the groove 11; and the multilayer non-stick coating is beneficial to improving the layering phenomenon of the non-stick coating, so that the uniformity of the non-stick coating is increased, and the non-stick performance and the uniformity of heat conduction of the coating 2 are further improved. In addition, when body 1 is stainless steel body, arouse easily that the stainless steel surface yellows when non-stick coating toasts, through setting up multilayer non-stick coating, can utilize non-stick coating to cover the surface that the stainless steel yellows effectively on the one hand, on the other hand is favorable to improving non-stick nature, improves user's use and experiences.

In this way, the coating 2 may assume the hue of the second pigment filler or a mid-tone of the hue of the first pigment filler and the hue of the second pigment filler.
Specifically, the second color filler is aluminum flake particles and/or silver particles. That is, one or both of silver particles and aluminum flake particles may be added to the surface layer 22. Specifically, silver paste and/or aluminum paste may be added to the coating so that aluminum flake particles and/or silver particles are present in the top layer 22 after the coating is cured. Therefore, the aluminum flake particles and/or silver particles are added into the surface layer 22, so that the surface layer 22 has silvery-white metallic luster, which is beneficial to realizing the metallic effect of the inner surface of the container 100, and particularly, when the body 1 is a stainless steel piece, the color of the surface layer 22 can be consistent with the color of the part which is not covered by the coating 2 in the body 1, namely the top wall of the protrusion 12, thereby improving the appearance aesthetic property of the container 100.
According to some alternative embodiments of the present invention, the bottom layer 21 comprises a white filler therein and the top layer 22 comprises aluminum flake particles and/or silver particles. Therefore, the white filler added in the bottom layer 21 can effectively cover the inner wall surface of the groove 11, and under the dual action of the bottom layer 21 and the aluminum flake particles and/or silver particles added in the surface layer 22, the surface layer 22 has better silvery metallic luster, so that when the body 1 is a stainless steel piece, the color of the coating 2 can be consistent with the color of the top wall part of the protrusion 11 which is not covered by the coating 2 in the body 1, and the appearance aesthetic property of the container 100 can be improved.
According to some embodiments of the present invention, the facing 22 comprises wear resistant particles, thereby facilitating further improvement of the wear resistance of the facing 22, thereby improving the service life of the coating 2 system.
Specifically, the wear resistant particles of the facing 22 are uniformly distributed in the facing 22. This is advantageous in order to further increase the wear resistance of the base layer 21 and thus the service life of the coating 2 system.
In some alternative embodiments, the wear resistant particles in facing layer 22 are Al2O3Particles of SiO2At least one of the particles and the SiC particles, that is, the wear-resistant particles may be Al2O3Particles of SiO2One of the particles and SiC particles may be Al2O3Particles of SiO2Two of the particles and SiC particles, or the wear-resistant particles are Al2O3Particles of SiO2Particles and SiC. Therefore, the method is not only beneficial to improving the hardness, the scratch and abrasion resistance and the chemical resistance of the coating 2 system, but also low in cost.
In some embodiments of the present invention, the bottom layer 21 includes a binder resin therein, and the binder resin is at least one selected from PES, PAI, PPS, PEEK, and PPSU. Further, the base layer 21 includes a fluororesin, which is at least one selected from PFA, PTFE, and EFP. Thereby, a long life non-stick coating can be provided.

Therefore, good bonding force between the surface layer 22 and the bottom layer 21 can be ensured, and the service life of the surface layer 22 is prolonged.
Specifically, the thickness of the bottom layer 21 gradually increases from the opening edge of the groove 11 to the bottom wall of the groove 11. From this, the thickness of the diapire department bottom 21 of recess 11 is thickest, through making the thickness of the diapire department bottom 21 of recess 11 thicker, be favorable to improving cohesion between the interior diapire of bottom 21 and recess 11 and cohesion between bottom 21 and the surface course 22, the life of coating 2 has been improved, and can improve the heat conductivility of coating 2 bottom, thereby make the heat conduct to recess 11 lateral wall fast, promote the holistic heat conduction homogeneity of coating 2, avoid the heat to concentrate on recess 11 diapire simultaneously, lead to coating 2 to appear the hot crack, improve coating 2's scratch resistance, can improve the heat of coating 2 top air simultaneously, thereby can make the heat homogeneity promotion of the culinary art surface of whole container 100.
In some embodiments of the present invention, the thickness of the bottom layer 21 of the lower portion of the side wall of the groove 11 is the same as the thickness of the bottom layer 21 of the bottom wall of the groove 11. Specifically, the thickness of the bottom layer 21 on the upper portion of the side wall of the recess 11 gradually increases in the direction from the opening of the recess 11 to the bottom wall of the recess 11, and the thickness of the bottom layer 21 on the lower portion of the side wall of the recess 11 is the same as the thickness of the bottom layer 21 on the bottom wall of the recess 11. Therefore, the bonding force between the bottom layer 21 and the inner bottom wall of the groove 11 and the bonding force between the bottom layer 21 and the surface layer 22 are improved, and the service life of the coating 2 is prolonged.
According to some embodiments of the present invention, the thickness of the coating 2 located at the bottom wall of the recess 11 is greater than the thickness of the coating 2 located at the side wall of the recess 11. Specifically, the thickness of the coating 2 gradually increases in a direction from the opening edge of the groove 11 to the bottom wall of the groove 11.

According to some embodiments of the utility model, it is shown with reference to fig. 3-4 that the degree of depth of recess 11 is h, and the value range of h is: 0.05-0.3 mm. Further, the value range of h is: 0.1-0.2 mm. For example, h is 0.12mm, 0.15mm, 0.18mm or 0.19 mm. Specifically, on one hand, the protrusion 12 is opposite to the groove 11, and the depth h of the groove 11 is limited, so that the height of the protrusion 12 is limited, that is, the height of the protrusion 12 is equal to the groove depth h, and the depth h of the groove 11 is not less than 0.05, so that the problem that the coating 2 is shallow due to the small groove depth can be avoided, the coating 2 is prevented from being scratched, and the scratch resistance of the coating 2 is improved.
According to some embodiments of the present invention, a plurality of protrusions 12 are disposed on the inner surface of the body 1, and protrude from the inner surface of the body 1, and the circumferential wall of the plurality of protrusions 12 and the inner surface of the body 1 define the groove 11. For example, a portion of the inner surface of the body 1 is raised to form a plurality of spaced projections 12, i.e. the projections 12 and the body 1 are one piece, and the peripheral wall of the projections 12 and the remainder of the inner surface of the body 1 may define the recess 11. Therefore, the top wall of the protrusion 12 is not provided with the coating 2, the peripheral wall of the protrusion 12, namely the side wall of the groove 11 and the bottom wall of the groove 11 are provided with the coating 2, so that in the use process of the container 100, tools such as a turner and the like are in contact with the protrusion 12 and cannot extend into the groove 11, and the coating 2 cannot be scratched, and the container is simple in structure and convenient to process.

It is understood that the top wall of the projection 12 refers to the end surface of the free end of the projection 12, and the end of the projection 12 connected to the body 1 is the bottom wall.
In the related art, in order to enhance the strength of the columnar bump, the diameter of the bump tends to be relatively large, so that although the bump can provide a certain shovel resistance, the area of the inner wall surface of the groove 11 is reduced due to the large bump, the area of the non-stick coating is reduced, and the coverage of the coating 2 is reduced.
In view of this, according to the container 100 of the embodiment of the present invention, the area of the top wall of the protrusion 12 is S1, the area of the bottom wall of the protrusion 12 is S2, and the ratio of S1 to S2 ranges from 2% to 40%, so as to increase the surface area of the side wall of the groove 11, on one hand, increase the coverage rate of the coating 2, improve the adhesion of the coating 2 on the protrusion 12, improve the scratch resistance and non-stick property of the coating 2, on the other hand, facilitate the uniform flow of the coating 2, and reduce the accumulation of the coating 2 on the lower portion of the peripheral wall of the protrusion 12, when the container 100 is heated, reduce the concentration of heat at the position, reduce the formation of hot cracks on the coating 2, improve the adhesion and scratch resistance of the coating 2, further improve the uniformity of heat conduction of the coating 2 attached on the upper portion, and enable the included angle at the connection between the peripheral wall of the protrusion 12 and the bottom wall of the protrusion 12 to be within a proper range, the flowing of the coating 2 on the peripheral wall of the bulge is slowed down, so that the layering phenomenon of the coating 2 formed by the gravity phenomenon is reduced, the coating 2 has a certain thickness at the groove 11, and the non-stick performance, the wear resistance and the scratch resistance of the coating 2 are improved. In addition, it is advantageous to secure the coupling strength between the projection 12 and the body 1 and the structural strength of the projection 12.
Specifically, the cross-sectional area of the projection 12 gradually increases in a direction from the top wall of the projection 12 to the bottom wall of the projection 12. Therefore, the heat transfer capacity of the bottom of the coating 2 can be improved, and the overall heat conduction performance of the coating 2 is improved.
In some embodiments of the present invention, the ratio of S1 to S2 is in the range of 10% to 35%. Therefore, the connection strength between the protrusion 12 and the body 1 is ensured, the surface area of the inner wall surface of the groove 11 is increased, the coverage rate of the coating 2 is increased, the non-stick performance is improved, and the structural strength of the protrusion 12 can be ensured.
Further, the ratio of S1 to S2 ranges from 15% to 25%. For example, the ratio of S1 to S2 is 16%, 17%, 18%, 19%, 20%, 21%, 22%, or 24%. This is advantageous in further increasing the surface area of the side wall surface of the recess 11.
