Description

프레스 방식을 이용한 조리용기의 표면 가공방법{Press method using the surface of the cookware}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking method,

본 발명은 프레스 방식을 이용한 조리용기의 표면 가공방법에 관한 것으로 상세하게는 조리용기를 구성하는 판재 재료의 표면에 논-스틱(NON-STICK) 기능을 구현할 수 있도록, 표면에 돌출 면을 형성할 수 있도록 한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of processing a surface of a cooking vessel using a pressing method, and more particularly, to a method of forming a surface of a plate material constituting a cooking vessel, .

일반적으로 판재를 이용한 조리용기(솥, 프라이팬, 웍, 냄비, 압력밥솥 등)는 열전도율과 위생을 기본으로 하고 있다.In general, cooking vessels (pot, frying pan, wok, pot, pressure cooker, etc.) using plate materials are based on thermal conductivity and hygiene.

상기의 조리용기를 구성하는 재료에서 판재는 사용자의 편의에 따라 알루미늄 또는 스테인리스가 사용되며, 원가를 절감하면서 유도가열을 이용한 가열도구(IH-INDUCTION)를 사용할 수 있도록 알루미늄과 스테인리스를 혼합한 복합 판재가 사용되고 있다.
In the material constituting the above-described cooking vessel, aluminum or stainless steel is used for the user's convenience, and a composite plate in which aluminum and stainless steel are mixed so as to use a heating tool (IH-induction) Is used.

상기와 같은 조리용기의 사용에서 조리용기의 사용수명을 결정하는 것은 조리용기 내면의 논-스틱이다. 이러한 이유로 다양한 코팅 기술(도료 및 코팅 방법)을 활용에 조리용기 내면에 코팅력을 강화하게 있으나, 조리를 하는 과정에서 조리용기 내면과 접하는 조리도구(주걱, 숟가락, 집게, 뒤집게 등)에 의해서 조리용기 내면의 긁힘 발생으로 표면이 손상되어 조리용기 내면에 음식이 눌러 붙는 현상이 발생하므로 조리용기의 기능상실로 사용이 불가한 것이다.
In determining the service life of the cooking vessel in the use of the cooking vessel as described above, it is a non-stick on the inner surface of the cooking vessel. For this reason, the coating force is strengthened on the inner surface of the cooking container by utilizing various coating techniques (coating and coating method). However, by the cooking tools (spatulas, spoons, tongs and back tongs etc.) The surface of the cooking cavity is scratched due to scratches on the inner surface of the cooking cavity and the food is pressed against the inner surface of the cooking cavity.

상기와 같은 문제점을 감안하여 조리용기 표면과 조리도구의 접촉 면을 감소시켜 조리용기 내면의 손상을 방지할 수 있도록 하는 대표적인 방안이 특허등록 제10-0804387호(이하 공지특허)에 공지되어 있다.
In view of the above problems, a representative method for reducing the contact surface between the surface of the cooking container and the cooking tool to prevent the inner surface of the cooking container from being damaged is disclosed in Patent Registration No. 10-0804387 (hereafter, known patent).

상기의 공지특허를 살펴보면, 조리용기 표면을 구성하는 판재에 일정 모양을 제공하는 필름을 부착하고, 상기의 판재 표면에 잉크를 도포한 후 부식용액을 이용하여 판재를 부식하므로, 잉크의 도포에 의해서 부식되지 않는 표면과 부식 면을 이용하여 판재의 음각부, 양각부를 형성하고, 상기의 음각부, 양각부에 코팅 후 양각부의 코팅층을 제거하므로, 조리용기 내면의 음각부에만 코팅층을 형성하는 것을 특징으로 하고 있다.
In the above known patent, a film providing a predetermined shape is attached to a plate material constituting the surface of the cooking container, and after coating the ink on the plate material, the plate material is corroded by the corrosion solution, The coating layer is formed only on the depressed portion of the inner surface of the cooking container since the depressed portion and the embossed portion of the plate are formed using the surface which is not corroded and the surface of corrosion and the coating layer of the embossed portion is removed after coating the depressed portion and the embossed portion. .

그러나 상기의 공지특허의 경우 판재에 음각부와 양각부를 형성하는 방법이 매우 복잡하고, 여러 공정을 진행하여 음각부에만 코팅층을 형성하므로, 실제 조리용기에 적용하는데 많은 어려움이 있다.
However, in the case of the above-mentioned known patent, the method of forming the engraved portion and the embossed portion in the plate material is very complicated and the coating layer is formed only on the engraved portion through various processes.

이러한 문제는 코팅층을 구성하는 얇은 필름의 부착이 조리용기와 면밀하게 접촉되지 않아 필름과 판재 사이에 잉크가 쉽게 침투하여 사용자가 요구하는 음각부 모양을 구현할 수 없으며, 필름부착을 고도의 숙련공만이 진행할 수 있어 작업의 효율성 저하로 인해 제품의 가격 상승을 유발하여 제품의 경쟁력이 저하하므로, 큰 실효성이 없다 할 것이다.
This problem is caused by the fact that the adhesion of the thin film constituting the coating layer does not come into close contact with the cooking vessel, so that the ink easily penetrates between the film and the plate material, so that the shape of the engraved portion required by the user can not be realized. It will not be very effective because the competitiveness of the product will be lowered due to the increase in the price of the product due to the decrease in the efficiency of the work.

본 발명은 종래의 공지된 판재의 음각부와 양각부를 형성하는 공정을 간소화하여 제품의 생산성을 향상하고, 생산하는 제품의 품질의 균일화를 통해 대량 생산을 통한 원가 절감과 제품의 경쟁력을 갖도록 하는 조리용기 제공하는데 그 목적이 있다.
The present invention improves the productivity of a product by simplifying the process of forming the engraved portion and the embossed portion of the known plate material, and reduces the cost through mass production by making the quality of the produced product uniform, The purpose is to provide the courage.

본 발명은 상기의 과제를 해결하는 수단으로, 조리용기를 구성하는 판재의 표면에 돌출부가 형성될 수 있도록, 프레스 장치를 이용하여 판재 표면에 강제적으로 음각면을 형성하므로, 이로 인해 반대로 다른 면에는 양각부를 형성하는 조리용기를 제공하는 것이다.
In order to solve the above problems, the present invention provides a method of producing a cooking container, which comprises a pressing device for forcibly forming a concave surface on a surface of a plate material so that a protrusion can be formed on a surface of the plate material constituting the cooking container, To provide a cooking vessel which forms an embossed portion.

본 발명은 상기의 해결 수단을 통해, 논-스틱 기능을 갖는 조리용기를 생산함에 있어, 프레스 방식을 통한 신속하고 균일화된 작업을 통해 생산성 증대를 통한 원가절감 및 양질의 제품을 생산할 수 있도록 하므로, 생산하는 제품의 경쟁력을 통해 기업 이윤과 양질의 제품을 사용하는 소비자 만족도를 증대하는 효과가 있는 것이다.
