Therefore, the present invention solves the conventional problems by providing a molding and a simple appearance so that the groove frame of the boundary portion of the inner container and the outer container is not formed.

Description

인서트 금속용기{Insert Metal Courage}Insert Metal Courage}

본 고안은 내통과 외통이 금속과 플라스틱으로 이루어진 용기에 관한 것으로서, 특히 내부용기외 외부를 감싸면서 플라스틱으로 인서트 사출성형되는 외부용기가 성형된 상태에서 심플한 외관을 제공하면서 성형을 용이토록 한 것이다.The present invention relates to a container made of metal and plastic, the inner cylinder and the outer cylinder, in particular, to facilitate the molding while providing a simple appearance in a state in which the outer container to be molded injection molded into the plastic surrounding the outside of the inner container.

일반적으로 금속재질(본 고안에서는 위생상태가 우수한 스텐레스를 사용함)의 내부용기에 플라스틱재질의 외부용기로 이중사출로 제조된 용기는 뜨거운 음식을 담아도 용기의 취급이 용이하고 다양한 디자인을 제조가 가능하면서 음식물의 보관 및 음식으로 유해물질이 유입되는 것을 방지하여 안전한 식생활을 할 수 있도록 하여 요즘 많이 사용되고 있는 것이다.In general, a container manufactured by double injection into an outer container of plastic material in an inner container of a metal material (in this design, a stainless steel having excellent hygiene) is easy to handle even if it contains hot food, and various designs can be manufactured. While keeping food and preventing the introduction of harmful substances into the food to enable a safe diet is being used a lot today.

이러한 이중사출로 제조된 용기는 금속재질의 내부용기가 플라스틱재질의 외부용기로부터 분리되지 않도록 하기 위하여 대부분 금속재질의 내부용기의 상측 테두리부를 동그랗게 말아지도록(컬링가공) 프레스로 가공한 후 사출금형기에 넣어 내부용기의 외측을 감싸면서 내부용기의 상측 테두리부의 동그랗게 말아진 부분(컬링부)의 내측으로 수지가 채워지도록 외부용기를 형성하여 내부용기와 외부용기가 임의적으로 분리되지 않도록 성형되어진 것이다.In order to prevent the inner container of the metal material from being separated from the outer container of the plastic material, the container manufactured by the double injection is processed by a press so that the upper edge of the inner container of the metal material is curled (curling), and then the injection molding machine is The outer container is formed so as to surround the outer side of the inner container and the resin is filled into the inside of the circularly curled portion (curling part) of the upper edge of the inner container.

그러나 내부용기에 외부용기가 빠지지 않도록 하기 위하여 형성된 내부용기의 동그랗게 말아진 테두리부분(킬링부)은 프레스 가공으로 성형이 쉬우나 이것의 단점이 내부용기의 외측으로 외부용기를 인서트 사출성형 할 경우에 내부용기의 테두리부분과 외부용기가 형성된 하측 부분에 내입되는 홈테가 발생되어 이러한 홈테로 음식물 찌꺼기 등의 이물질이 끼이게 되면서 음식을 담는 용기로써 위생상 좋지 않은 문제가 있는 것이었다.However, the rounded edges (killing parts) of the inner container formed to prevent the outer container from falling out of the inner container are easy to be formed by press working, but the disadvantage thereof is that when the insert is molded into the outer container to the outside of the inner container There was a problem in the hygiene as the container containing the food was trapped by foreign matters such as food waste caused by the groove rim is formed in the lower portion formed in the rim and the outer container of the container.

또한 이러한 홈테에 끼워진 이물질은 설겆이를 하여도 잘 씻겨지지가 않아 이물질의 제거가 쉽지 않게 되면서 용기를 깨끗하게 설겆이를 하는 것이 불가능하여 음식을 담는 용기로서 상당히 비위생적인 것이었다.In addition, the foreign matter inserted in the home frame was not easily washed even after washing, so that it was not easy to remove the foreign matter, and it was impossible to clean the container cleanly, which was quite unsanitary as a container for food.

따라서 종래의 공개실용신안 20-2010-0000304에 내부용기의 동그랗게 말아진 상측 테두리부를 외부용기가 완전히 감싸지도록 하여 인서트 사출토록 한 것이 제안되었으나 이것은 외부용기가 사출성형될 때 테두리부를 완전히 감싸게 되면서 외부용기의 두께가 두껍게 형성되는 것이어서 사출성형이 어려운 것이었다.Therefore, it is proposed to insert the outer edge of the inner rim of the inner container by completely enclosing the insert in the conventional utility model 20-2010-0000304. Because the thickness of the thick formed was difficult injection molding.

이러한 것은 사출성형이 두껍게 사출될 경우에 고온으로 된 사출물이 사출성형기를 통해 주입되어 내부용기를 감싸도록 주입되어 주입된 사출물이 식혀져 굳기까지 상당히 시간이 걸리게 되어 생산되는 시간이 오래 걸리게 되고 또한 변형이 발생되며 외부용기의 두께가 두꺼워짐으로써 제조단가가 비싸지게 되는 것이고 또한 디자인이 투박해지고 볼품이 없어져 상품성이 떨어지는 것이었다.This is because when the injection molding is injected thick, a high temperature injection is injected through the injection molding machine to wrap the inner container, which takes a long time until the injected injection cools and hardens, and it takes a long time to produce and deform. This is caused by the increase in the thickness of the outer container is expensive manufacturing cost and was also poor in design due to the clunky design and the lack of look.

또한 내부용기의 테두리부까지 감싸지게 외부용기를 사출할 경우 사출 후 내부용기의 테두리부와 외부용기의 경계선 부분에 사출압에 의하여 뼈져나오는 이물질들이 굳어지면서 이바리가 남게 되어 이러한 이바리를 제거하는 별도의 후가공 작업을 해야하는 불편한 문제가 있는 것이었다.In addition, when injecting the outer container to be wrapped up to the inner edge of the inner container, after injection, the foreign matter that is boned by the injection pressure hardens on the edge of the inner container and the boundary of the outer container. There was an uncomfortable problem of having to do post-processing.

따라서 본 고안은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 내부용기에 외부용기가 인서트 사출성형할 때 사출의 용이성을 제공하면서 사출된 상태에서의 디자인이 우수하면서 위생적인 용기를 제공하기 위한 것이다.Therefore, the present invention has been made to solve the above-mentioned conventional problems, to provide a hygienic container with an excellent design in the injected state while providing the ease of injection when the outer container is insert injection molded into the inner container. will be.

상기의 목적을 달성하기 위하여 본 고안은 내부용기의 말려지는 테두리부에 "V" 컷팅라인에 의해 직각으로 절곡되는 절곡부를 형성하여 테두리의 상측부가 말려지도록 1차 프레스 가공한 상태에서 "V" 컷팅라인을 내측방향으로 접어줌으로써 사출성형시 외부용기가 절곡부의 하단면에 성형되도록 하여 홈테가 발생되지 않도록 하면서 디자인이 깔끔하게 성형되어지게 되는 것이다.In order to achieve the above object, the present invention forms a bent portion that is bent at a right angle by the "V" cutting line at the curled edge of the inner container, thereby cutting the "V" in a state where the upper side of the edge is first pressed. By folding the line in the inward direction, the outer container is molded at the bottom surface of the bent portion during injection molding, so that the design is neatly molded while the groove frame is not generated.

따라서 상술한 바와 같이 본 고안은 음식물의 변질 및 유해물질의 투입을 차단하도록 이중사출로 된 용기로 제조함과 동시에 내부용기의 테두리부의 하단으로 테두리부의 측면과 동일선상으로 외부용기를 사출성형토록 하여 이물질이 끼지 않도록 제조되어 위생적으로 사용할 수 있으며 동시에 깔끔한 외관을 제공하여 제품의 품질향상을 제공하게 되는 것이다.Therefore, as described above, the present invention is manufactured with a double-injection container to block the deterioration of food and the introduction of harmful substances and at the same time injection molding the outer container in the same line as the side of the edge to the lower edge of the inner container It is manufactured to prevent foreign substances and can be used hygienically, and at the same time, it provides a neat appearance and provides an improvement in product quality.
