Description
본 발명은 일회용 용기에 관한 것으로서, 특히 일회용 용기의 강도 및 질감의 향상을 위해 갈대 또는 사탕수수에 옥수수 또는 왕겨를 혼합한 혼합물을 이용하는 일회용 용기 제조방법에 관한 것이다.The present invention relates to a disposable container, and more particularly to a method for producing a disposable container using a mixture of corn or rice husk in the reed or sugar cane to improve the strength and texture of the disposable container.
일반적으로 산업이 발달하면서 인간의 편의를 위해 일회 사용하고 버릴 수 있는 일회용 용기가 급격하게 생산되고 있는데, 이러한 일회용 용기는 일반 가정은물론이고 야외에서 음식물을 섭취할 경우 음식물 저장용기의 세척 및 운반 등이 번거롭기 때문에 많이 사용되고 있다.In general, as the industry develops, disposable containers that can be used and discarded once for human convenience are rapidly produced. Such disposable containers are not only common households, but also the washing and transport of food storage containers when food is taken outdoors. It is used a lot because it is troublesome.
이와 같은 일회용 용기는 주로 제조비가 저렴한 발포성 수지나 합성수지를 사용하여 제조하였는데, 사용 후 자연 속에 방치하여 폐기할 경우 자연분해가 되지 않아 폐기처리시간이 오래 걸리고 토양을 오염시키며, 소각하는 경우 발암의 원인인 다이옥신과 같은 각종 유해물질이 용출되어 대기를 오염시키는 문제점이 있다.Such disposable containers are mainly manufactured using inexpensive foam resins or synthetic resins, but if left unused in nature after use, they do not decompose naturally, which takes a long time for disposal and contaminates the soil. Various harmful substances, such as phosphorus dioxins, are eluted to contaminate the air.
따라서, 근래에는 화학제품의 일회용 용기 대신에 종이나 전분, 갈대와 같은 환경 친화적인 원료를 사용하여 제조하고 있다.Therefore, in recent years, instead of disposable containers of chemical products, they are manufactured using environmentally friendly raw materials such as paper, starch and reed.
그러나, 종이 제품의 일회용 용기는 폐기시 환경을 오염시키지는 않지만, 나무를 사용함으로써 지구의 허파라 할 수 있는 삼림의 파괴로 인한 환경 문제에 직면하고 있고, 생산비가 높아 경제성이 낮다.However, although disposable containers of paper products do not pollute the environment at the time of disposal, they face environmental problems due to the destruction of the forest, which is the lungs of the earth by the use of wood, and the production cost is high and the economy is low.
그래서, 종이와 같은 특성을 갖는 갈대 또는 사탕수수 펄프를 이용한 일회용 용기가 선 보였는데, 이러한 일회용 용기는 종이와 달리 환경을 해치지 않으면서 생산비가 저렴한 이점이 있지만, 잘 찢어지고 질감이 거칠어 물성이 나쁘다.Thus, a disposable container using reed or sugarcane pulp having paper-like properties has been shown, which has the advantage of low production cost without harming the environment, unlike paper, but has poor physical properties due to its good tearing and rough texture. .
그리고, 전분, 옥수수, 왕겨, 고구마 등 어느 하나의 원료를 이용하여 제조된 일회용 용기는 자연 분해 시간이 짧고, 토양에 비료가 되며, 생산비가 저렴한 이점이 있지만, 이 또한 잘 깨어지거나 찢어지고 질감이 거칠어 물성이 나쁘다.In addition, the disposable container manufactured using any one raw material such as starch, corn, rice husk, sweet potato, etc. has the advantages of short natural decomposition time, fertilizer to the soil, and low production cost, but this is also well cracked, torn and textured. Rough and bad physical properties.
본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서,환경 친화적이면서 생산비가 저렴하고, 강도 및 질감이 향상된 일회용 용기를 제조하는 일회용 용기 제조방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, an object of the present invention is to provide a disposable container manufacturing method for producing a disposable container with an environmentally friendly, low production cost, and improved strength and texture.

10 : 일회용 용기10: disposable container
상기한 과제를 해결하기 위한 본 발명에 따른 일회용 용기의 제조방법은 미세한 분말형태로 분쇄된 갈대와 왕겨, 옥수수, 사탕수수 중 갈대 또는 사탕수수를 포함하여 2가지 이상을 혼합하고, 반죽한 다음, 예열된 금형에 넣고 압출 성형한다.Method for producing a disposable container according to the present invention for solving the above problems is mixed with two or more, including reeds and chaff, corn, sugar cane, reeds or sugar cane, ground in fine powder form, kneaded, It is placed in a preheated mold and extruded.
이하, 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
상기 본 발명에 따른 일회용 용기의 제조방법은 갈대와 사탕수수, 옥수수, 왕겨를 각각 분쇄하여 미세한 분말로 만드는(S10) 제1 단계와, 상기 제1 단계에서 분쇄 완료된 갈대 분말, 사탕수수 분말, 옥수수 분말, 왕겨 분말 중 갈대 분말 또는 사탕수수 분말을 포함하여 2 가지 이상의 분말을 혼합하고(S20), 이 혼합물에 물과 식용 아교를 첨가하여 반죽하는(S30) 제2 단계와, 상기 반죽을 예열된 금형에 넣고(S40), 프레스를 이용하여 가압 성형하는(S50) 제3 단계와, 상기 성형된 일회용 용기를 금형으로부터 분리한(S60) 다음, 식물성 유질로 코팅시켜 건조시키는(S70) 제4 단계로 이루어진다.The method of manufacturing a disposable container according to the present invention is a reed and sugar cane, corn, chaff crushed to each step to make a fine powder (S10) and the first step, the crushed reed powder, sugar cane powder, corn A second step of mixing two or more powders including powder, chaff powder, reed powder or sugarcane powder (S20), adding water and edible glue to the mixture (S30), and preheating the dough. The third step of putting into a mold (S40), press-molding using a press (S50), and separating the molded disposable container from the mold (S60), and then coating and drying with a vegetable oil (S70) Is made of.
상기 제1 단계에서(S10), 상기 갈대와 사탕수수는 분쇄하기 전에 종이와 같은 특성을 갖는 펄프로 만들어지는데, 갈대 펄프 또는 사탕수수 펄프는 닥나무 등으로 제조된 고가의 종이에 비하여 주위에서 흔하면서도 저렴하게 구할 수 있고, 섬유 길이가 1.2 ~ 1.7mm로 활엽수의 섬유와 비슷하고 섬유 지름이 12 ~ 20 ㎛로 길이와 폭의 비가 침엽수와 같아 탄력과 강도가 크며, 물이 잘 통과되지 않는 수불침투성을 갖고 있어 물과 같은 음식물 저장이 가능하다.In the first step (S10), the reed and sugar cane is made of pulp having paper-like properties before grinding, although reed pulp or sugar cane pulp is more common in the surroundings than expensive paper made of paper mulberry, etc. It is available at low cost, and the fiber length is 1.2 ~ 1.7mm, similar to the hardwood fiber, and the fiber diameter is 12 ~ 20㎛, the ratio of length and width is the same as the conifers. It is possible to store food such as water.
상기 옥수수 또는 왕겨 또한 주위에서 저렴하면서도 흔하게 구할 수 있는 식물성 원료이다.The corn or chaff are also vegetable raw materials that are inexpensive and commonly available around.
이와 같은 갈대 펄프, 사탕수수 펄프, 옥수수, 왕겨는 분쇄기에 의해 용이하게 분쇄되어 분말화된다.Such reed pulp, sugarcane pulp, corn, and chaff are easily crushed and powdered by a grinder.
상기 제2 단계에서(S20, S30), 일회용 용기의 형상 또는 사용목적 등에 따라 갈대 분말과 옥수수 분말을 1:1 비율로 혼합하거나, 갈대 분말과 왕겨 분말을 1:1 비율로 혼합, 또는 갈대 분말과 옥수수 분말, 왕겨 분말을 1:1:1 비율로 혼합하여 각 원료의 장점을 살리면서 단점을 보완한다.In the second step (S20, S30), according to the shape or purpose of use of the disposable container, the reed powder and corn powder is mixed in a 1: 1 ratio, or the reed powder and chaff powder in a 1: 1 ratio, or reed powder And corn powder, chaff powder in a 1: 1: 1 ratio to take advantage of each raw material to compensate for the shortcomings.
즉, 갈대는 종이와 같은 특성을 갖고 있어 탄력과 강도가 크고 수분이 투과되지 않는 불투성을 가진 장점이 있는 반면에, 잘 찢어지고 변형되기 쉬울 뿐 아니라 질감이 거친 단점이 있다. 또, 옥수수 또는 왕겨는 질감은 좋은데 반해 변형되기 쉽고 깨어지기 쉽다.In other words, reeds have the same properties as paper, which has the advantage of having elasticity and strength and impermeability to which moisture is not permeable, while being easily torn and deformed, and having a rough texture. In addition, corn or chaff have a good texture, but are easily deformed and broken.
그러나, 본 발명에 의한 일회용 용기는 갈대와 옥수수 또는 왕겨가 혼합되어 제조되기 때문에 조직이 매우 치밀해져 잘 찢어지거나 깨지지 않고, 변형이 되지 않으면서 질감이 좋은 이점이 있다.However, since the disposable container according to the present invention is manufactured by mixing reeds with corn or rice husks, the tissue is very dense and does not tear or break well, and the texture is excellent without deformation.
또한, 갈대 분말을 포함한 상기 혼합물에 사탕수수 분말을 더 첨가하여 강도를 향상시킬 수 있다.In addition, the sugar cane powder may be further added to the mixture including the reed powder to improve the strength.
또한, 사탕수수 펄프도 상기한 바와 같이 갈대 펄프처럼 종이과 같은 특성을 갖고 있으므로, 갈대 펄프의 공급이 원활하게 이루어지지 않는 경우 갈대 펄프의 대체 원료로 사용할 수 있다.In addition, the sugar cane pulp has the same characteristics as the paper as the reed pulp as described above, and can be used as an alternative raw material of the reed pulp when the reed pulp is not supplied smoothly.
반대로, 사탕수수 펄프를 포함하여 일회용 용기를 제조하다가 사탕수수 펄프의 공급이 원활하게 이루어지지 않는 경우, 사탕수수 펄프 대신 갈대 펄프로 대체하여 제조할 수 있다.On the contrary, when the disposable container including the sugar cane pulp is not produced while the supply of the sugar cane pulp is not performed smoothly, it can be prepared by replacing with the reed pulp instead of the sugar cane pulp.
그리고, 상기 혼합물에 물과 식용 아교를 첨가하여 반죽하는데, 상기 반죽은 상기 혼합물이 55~65 중량 %이고, 물이 25~35 중량 %이고, 식용 아교가 2 ~ 15 중량 %로서, 상기 혼합물에 따라 조절된다.Then, the mixture is kneaded by adding water and edible glue, wherein the dough is 55 to 65% by weight of the mixture, 25 to 35% by weight of water, and 2 to 15% by weight of edible glue to the mixture. Adjusted accordingly.
상기 제3 단계에서(S40, S50, S60), 상기 금형은 일회용 용기가 사용목적 등에 따라 대접형, 접시형 등으로 성형될 수 있도록 일정한 형상을 갖으며, 상기 제2 단계에서의 반죽이 넣어지기 전에 60 ~ 80℃ 정도로 예열된다.In the third step (S40, S50, S60), the mold has a certain shape so that the disposable container can be molded into a serving type, dish type, etc. according to the purpose of use, and the dough is put in the second step Before it is preheated to 60 ~ 80 ℃.
상기처럼 예열된 금형에 반죽을 넣고 프레스를 이용하여 10 ~ 30초 동안 가압하여 원하는 형상을 얻는다.Put the dough in the preheated mold as described above and press for 10 to 30 seconds using a press to obtain the desired shape.
이 때, 상기 금형의 예열 온도 및 프레스 공정시간은 원하는 일회용 용기의 형상, 즉 두께에 따라 적절하게 조절해야 한다.At this time, the preheating temperature and the press process time of the mold should be appropriately adjusted according to the shape of the desired disposable container, that is, the thickness.
다시 말해서, 금형의 예열 온도가 제조하고자 하는 일회용 용기에 필요한 가열 온도보다 낮으면 성형 시간이 오래 걸리고 강도가 약해지며, 반대로 금형의 예열 온도가 일회용 용기의 가열온도보다 높으면 일회용 용기의 원료가 식물성이기때문에 일회용 용기가 타고, 이로 인해 제조 과정에서 화재의 위험이 있다.In other words, if the preheating temperature of the mold is lower than the heating temperature required for the disposable container to be manufactured, the molding takes a long time and the strength is weak. On the contrary, if the preheating temperature of the mold is higher than the heating temperature of the disposable container, the raw material of the disposable container is vegetable. Because of this, disposable containers burn, which creates a risk of fire in the manufacturing process.
또한, 프레스 공정시간이 길수록 금형에 넣어진 반죽에 가해지는 압력이 높아짐을 의미하는데, 이 프레스 공정시간이 짧아 제조하고자하는 일회용 용기에 충분한 압력이 가해지지 않으면 원하는 형상이 나오지 않고, 프레스 공정시간이 길어 제조하고자 하는 일회용 용기에 필요 이상의 압력이 가해지면 반죽이 금형에 눌러붙는 문제가 생긴다.In addition, the longer the press process time, the higher the pressure applied to the dough put into the mold. If the press process time is short and a sufficient pressure is not applied to the disposable container to be manufactured, the desired shape does not come out and the press process time is When longer than necessary pressure is applied to the disposable container to be manufactured, the dough will stick to the mold.
상기 제4 단계에서(S70), 성형이 완료된 일회용 용기(10)는 프레스 공정을 통해 적절히 건조되어 있는 상태이고, 방수, 방유 등의 목적으로 식물성 유질로 코팅되면 강도 및 질감이 더욱 향상된다.In the fourth step (S70), the molded disposable container 10 is properly dried through a press process, and when coated with vegetable oil for the purpose of waterproofing and oilproofing, the strength and texture are further improved.
한편, 이와 같이 갈대와 사탕수수, 옥수수, 전분을 2가지 이상 혼합하여 이 혼합물을 이용하여 제조된 성형품은 환경 친화적이면서, 저렴하고, 강도 및 질감이 좋으므로 본 발명의 일회용 용기(10)에 국한하지 않고 사용될 수 있다.On the other hand, by molding two or more of the reeds and sugar cane, corn, starch as described above, the molded article produced using this mixture is environmentally friendly, inexpensive, and strength and texture is limited to the disposable container 10 of the present invention It can be used without.
그 일 실시예로서, 차량의 캬부레타에 공급되는 공기에 혼입된 먼지, 카본, 금속 분말, 산화 생성물 등을 제거하기 위해 에어 필라멘트가 장착되는데, 상기 에어 필라멘트는 스틸 재질의 상부 커버와 하부 커버 사이에 종이 재질의 필터가 내장된 구조이다.In one embodiment, an air filament is mounted to remove dust, carbon, metal powder, oxidized products, etc., which are mixed into the air supplied to the carburetta of the vehicle, and the air filament is disposed between the upper cover and the lower cover made of steel. Paper filter built in.
여기서, 상기 에어 필라멘트의 상부 커버와 하부 커버를 스틸 대신에 본 발명의 일회용 용기와 같이 갈대와 옥수수 또는 왕겨를 혼합하여 제조하면 환경 친화적이고, 제조비가 저렴한 이점이 있다.Here, when the upper cover and the lower cover of the air filament is manufactured by mixing reeds with corn or rice husks as in the disposable container of the present invention instead of steel, there is an environmentally friendly, low production cost advantage.
상기와 같이 구성되는 본 발명에 따른 일회용 용기의 제조방법은 갈대, 사탕수수, 옥수수, 왕겨 등과 같이 환경 친화적이면서 쉽게 구할 수 있는 원료를 이용하여 제조하되, 종이와 같은 특성을 갖는 갈대 또는 사탕수수를 포함하여 2가지 이상의 원료를 혼합하여 제조하기 때문에 조직이 치밀해 잘 찢어지거나 변형되지 않고, 질감이 좋아지는 이점이 있다.The manufacturing method of the disposable container according to the present invention configured as described above is prepared using environmentally friendly and easily available raw materials such as reed, sugar cane, corn, chaff, etc., but the reed or sugar cane having the same characteristics as the paper Since two or more raw materials are mixed and manufactured, the structure is dense and thus does not tear or deform well, thereby improving the texture.
