It is an object of the second prior application to provide an aluminum cooking container manufacturing method which can increase the commerciality by coating only the inner surface and the outer surface of pure aluminum in order to coat the cooking vessel made of aluminum with a hard coating.

In addition, a specific method for achieving the purpose of the second application is to make the food cooking container 10 of aluminum as shown in Figure 6 and then the electrical shielding film which is an insulating material on the outer surface of the food cooking container 10 ( 11), and as shown in Fig. 7 and 8 put the food cooking container 10 in the coating tank 14 to energize the hard film (15) on the inner surface of the food cooking container (10) After the coating, as shown in FIG. 9, the pure aluminum is exposed to the outside by removing the electrical barrier film 11 coated on the outer surface of the food cooking container 10 with a bite.

The effect of the second application by this process is to coat the electrical barrier film 11 on the outer surface of the aluminum container 10 and put it in the coating tank 14 to apply a hard film 15 only on the inner surface, and again the electrical barrier film on the outer surface By eliminating (11), pure aluminum can be exposed so that the appearance is beautiful and the merchandise value can be increased.

However, the kitchen vessel produced by the second application is to apply a hard film 15 to the inner surface of the food cooking container 10 and to coat the electrical barrier film 11 so that pure aluminum is exposed on the outer surface, and then remove it with a bite. The process is required, and eventually, the electrical barrier 11 must be prepared and then disposed of rather than environmentally contaminated (environmental pollution due to the discarded electrical barrier 11), as well as greatly reducing productivity (electric barrier 11). With the repetition of the process of coating and removing again, the productivity of the electrical barrier film 11 itself is reduced.

An object of the present invention is to provide a method of manufacturing a kitchen vessel with a two-tone beauty and robustness while using a recyclable silicone rubber band as well as preventing environmental pollution and maximizing productivity.

Method for producing a kitchen vessel according to the present invention for achieving the above object,

(S1) step of providing a container with aluminum,

(S2) step of covering the silicone rubber band on the outer periphery of the container,

(S3) step of applying a hard film to the container,

(S4) A step of removing the silicone rubber band to provide an aluminum exposed surface is a basic feature of the technical method.

In addition, the repeated recycling of the silicone rubber band not only prevents environmental pollution, but also has the advantage of maximizing productivity due to simple operation, simple process, and recycling.

In addition, while providing a container by injection of aluminum or hydraulic pressing of an aluminum sheet, a partition line may be provided to correspond to a boundary of a portion on which a silicone rubber band is to be covered, thereby making it possible to reliably maintain a horizontal boundary of the hard film.

When explaining the preferred embodiment of the manufacturing method of the kitchen vessel according to the present invention with reference to the drawings.

10a and 10b is a process chart showing a manufacturing method of a kitchen vessel according to the present invention, Figure 11 is a perspective view showing a kitchen vessel according to the present invention.

As shown in Figure 10a, the manufacturing method of the kitchen container according to the present invention first provides a container 70 in aluminum (S1).

In this case, the container 70 may be manufactured by injection of aluminum or hydraulic pressing of an aluminum plate, and may have a partition line 71 so as to correspond to a boundary of a portion to be covered by the silicone rubber band 80 to be described later.

More specifically, as shown in FIGS. 10A to 11, the diameter extends from the bottom of the container 70 to form the lower convexly lowered portion, and at the same time, the diameter becomes gradually narrower toward the upper boundary of the partition line 71 of the middle portion. In the case of manufacturing to have a sense of stability of the upper and lower side light in general, the three-dimensional stability and the partition line 71 on the boundary of the portion where the silicone rubber band 80 is to be covered is clearly expressed so that the partition line when the silicone rubber band 80 is covered By 71, the horizontal state can be reliably maintained, and the horizontal boundary of the hard film 72 to be described later can be realized more smoothly.

At this time, when the container 70 is provided, processes such as an initial bite cutting process for removing surface roughness or perforation for attaching a handle (the final process and not described since it is a general technology) may be performed together.

Subsequently, as shown in FIGS. 10A and 10B, the container 70 is provided, and then the silicone rubber band 80 is covered on the outer circumference of the container 70 (S2), and the hard film 72 is disposed on the container 70. After coating (S3), the silicone rubber band 80 is removed to give the aluminum exposed surface 73 (S4) to complete the kitchen vessel of the two-tone (hard coating 72 portion and aluminum exposed surface 73 portion). You can do it.

Unlike general organic rubber, silicone rubber has excellent properties such as heat resistance, compression resistance, chemical resistance, non-toxicity, strength and low temperature elasticity due to its unique double-sided property having both inorganic and organic properties in molecular structure.

More specifically, silicone rubber has properties of tensile strength, elasticity, abrasion resistance and heat resistance far superior to that of general organic rubbers, and has good resilience, excellent compression resistance, and particularly good resistance to chemical solvents and harmless to human body. It is environmentally friendly as a non-toxic property, the strength is also superior to the general organic rubber, the physical properties of the property does not change even at low temperatures is applied to the present invention.

On the other hand, in the case of coating the hard coating 72 is to overcome the soft properties of aluminum and can be realized by anodizing (Anodising), etc., mainly in the range of -1 ~ 5 ℃ while using sulfuric acid as the electrolyte solution (aluminum 70; ) To maximize the hardness and wear resistance.

Method of manufacturing a kitchen vessel according to the present invention is that the core process is not different, after preparing the container 70, the silicone rubber band 80, the hard coating (72) and then remove the silicone rubber band 80 again aluminum It consists of the step of providing the exposed surface 73 (the process of giving glossiness by grinding | polishing hereafter shall belong to a normal category).

On the other hand, when the cover 140 is put on the container body 110 and the coating layer 120 as shown in the first application filed (120 coating coating, ceramic coating layer, fluorine coating layer or coating coating layer) coating layer for the entire container body 110 ( In addition to the provision of 120, the coating layer 120 is coated together to the surface of the cover 140, and the heterogeneous coating layer 120 applied to the surface of the cover 140 during anodizing causes a chemical reaction to deform the cover 140 itself. Of course, it is difficult to repeat the use of the cover 140 by the heterogeneous coating layer 120 at the time of recycling, but only one time limited use, in the present invention, after providing the container 70, the coating layer 120, such as the first application Since the silicone rubber band 80 is covered and the hard film 72 is immediately coated without the provision of the silicone rubber band 80, the silicone rubber having excellent properties such as heat resistance, compression resistance, chemical resistance, non-toxicity, strength and low temperature elasticity can be actively utilized. To the prevention of environmental pollution by the guarantee of repeated recycling, mention can be realized with the maximization of productivity.

Furthermore, when the hard film 15 is coated on the inner surface of the food cooking container 10 and the outer surface 11 is coated on the outer surface so as to expose pure aluminum on the outer surface of the food cooking container 10, the electrical barrier film 11 is removed. Of course, the environmental pollution by the disposal of the) and the decrease in productivity can not be avoided, but in the present invention, not only can the environmental pollution be prevented by repeated recycling of the silicone rubber band 80, but also a simple operation and a simple process and recycling Due to this, the productivity can be maximized together.

On the other hand, the manufacturing method of the kitchen vessel according to the present invention may further proceed to step (S5) to be processed more clearly by cutting the aluminum exposed surface 73 from which the silicone rubber band 80 is removed with a bite.

That is, even if the silicone rubber band 80 is covered to match the partition line 71 of the container 70, some errors may occur. When the cutting is performed with a bite to correctly correct the error in a horizontal state, the hard coating 72 This is useful in that it can make the boundary with) more clear.

The present invention is utilized in the field of manufacturing a two-tone kitchen container capable of maximizing productivity as well as preventing environmental pollution.
