Description

항균 용기 및 그 제조방법{ANTIBIOTIC CONTAINER AND PRODUCT METHOD THEREOF}TECHNICAL FIELD [0001] The present invention relates to an antibacterial container,

본 발명은 항균 용기 및 그 제조방법에 관한 것으로, 더욱 상세하게는 패각을 이용하여 살균 및 탈취 효과가 있는 항균 용기를 제조하는 방법과, 이에 의해 제조되는 항균 용기에 관한 것이다. The present invention relates to an antibacterial container and a method of manufacturing the same, and more particularly, to a method of producing an antibacterial container having a sterilizing and deodorizing effect by using a shell, and an antibacterial container manufactured thereby.

일반적으로 밀폐 용기는 음료나 음식물이 담긴 몸체에 뚜껑을 밀착시켜, 몸체의 내부가 밀폐되도록 하여 내용물을 이동 및/또는 보관할 수 있게 하는 용기로서, 이동시 몸체 내부의 내용물이 외부로 흘러나오는 것을 방지하고, 보관시에는 수분이 밖으로 빠져나가는 것을 방지하여 몸체에 담긴 내용물의 신선도를 오랫동안 유지시키는 기능을 한다.Generally, a hermetically sealed container is a container which allows a lid to be closely attached to a body containing beverages or foods, thereby allowing the inside of the body to be sealed to move and / or store the contents. , It prevents the water from escaping to the outside during storage and maintains the freshness of the contents contained in the body for a long time.

특히 플라스틱 용기는 쥬스나 우유 또는 청량음료 등의 다양한 음료의 개발로 인해 사용량이 계속 증가 추세에 있으며, 견과류나 장, 젓갈 종류와 김치 등의 음식물과 소주나 맥주와 같은 주류 또한 플라스틱 용기에 봉입하여 판매되고 있다.Especially, plastic containers have been continuously increasing in use due to the development of various drinks such as juice, milk or soft drinks. Also, nuts, chestnuts, fermented foods such as kimchi, and alcohol such as shochu and beer are also contained in plastic containers Are being sold.

그런데, 이러한 플락스틱 용기는 운반 및 보관의 편리함에 있어서는 좋은 반면에, 용기 내의 오염과 세균 감염으로 인해 대중이 식중독균을 포함한 세균의 침입에 무방비한 상태인 점이 문제가 되고 있다.However, such a flocked stick container is good in terms of convenience in transportation and storage, and is problematic in that the public is vulnerable to invasion of bacteria including food poisoning bacteria due to contamination and bacterial infection in the container.

또한, 용기 내의 일시적인 세척 또는 살균 처리는 외부로부터 세균의 침입을 잠시 지연시킬 수만 있을 뿐이며, 용기가 자체적인 살균력을 갖지는 못한다는 문제점이 있다.Further, the temporary cleaning or sterilization treatment in the container has a problem in that it can only temporarily delay the invasion of bacteria from the outside, and the container can not have its own sterilizing power.

실시예Example

도 1은 본 발명의 일 실시예에 따른 항균 용기의 제조방법이다. 이하 도 1을 참조하여, 본 발명의 일 실시예에 따른 항균 용기의 제조방법과, 이에 의해 제조되는 항균 용기에 대하여 설명하기로 한다.1 is a method for producing an antibacterial container according to an embodiment of the present invention. Hereinafter, a method of manufacturing an antibacterial container according to an embodiment of the present invention and an antibacterial container manufactured thereby will be described with reference to FIG.

일반적으로 PP(폴리프로필렌), PET(폴리에틸렌테레프탈레이트), PE(폴리에틸렌), PS(폴리스티렌), ABS(아크릴로니트릴 부타디엔 스티렌) 등의 범용성 고분자 합성 수지는 사출 성형에 의해 일상 생활에 필요한 용기로 제조된다.In general, general-purpose polymer synthetic resins such as PP (polypropylene), PET (polyethylene terephthalate), PE (polyethylene), PS (polystyrene) and ABS (acrylonitrile butadiene styrene) .

이와 같은 범용성 고분자 합성수지는 가공성 및 성형성이 뛰어나서 식품이나 음료의 보관용기 또는 각종 생활용품의 원재료로 널리 이용되고 있으나, 음식물을 장기간 보관하는 경우에는 세균 때문에 신선도가 떨어지는 문제점이 있다.Such a general-purpose polymer synthetic resin is excellent in processability and moldability, and is widely used as a raw material for storage containers for foods and beverages or various daily necessities. However, when foods are stored for a long period of time, freshness is deteriorated due to bacteria.

본 발명은 이와 같은 문제점을 해결하기 위해, 고분자 수지에 살균, 소독, 소취 및 탈취 기능을 가진 항균 기능성 물질을 첨가하고 사출 성형함으로써, 자체적인 항균 기능을 가진 항균 용기 및 그 제조방법을 제공하고자 한다.In order to solve such a problem, the present invention provides an antibacterial container having a self-antimicrobial function by adding an antibacterial functional substance having sterilization, disinfection, deodorization and deodorization function to a polymer resin and injection-molding the same, and a manufacturing method thereof .

구체적으로, 본 발명의 일 실시예에 따른 항균 용기 제조방법은, 도 1에 도시된 바와 같이 고분자 수지 용융 단계(S10)와, 항균 기능성 물질 첨가 단계(S20), 및 사출 성형 단계(S30)를 포함하며, 이하 각 단계별로 상세히 살펴보기로 한다.Specifically, as shown in FIG. 1, the method for manufacturing an antibacterial container according to an embodiment of the present invention includes a polymer resin melting step (S10), an antibacterial functional material adding step (S20), and an injection molding step (S30) And will be described in detail below.

고분자 수지 용융 단계(Polymer resin melting step ( S10S10 ):):

최종 재품의 원재료인 고분자 수지를 150℃ ~ 250℃에서 용융하여 액상으로 만든다. 이때, 고분자 수지로는 PP(폴리프로필렌), PET(폴리에틸렌테레프탈레이트), PE(폴리에틸렌), PS(폴리스티렌), ABS(아크릴로니트릴 부타디엔 스티렌) 중에서 어느 하나 이상을 선택할 수 있으며, 선택된 소재에 따라 용융 온도를 달리할 수 있다.The polymer resin, which is the raw material of the final product, is melted at 150 ° C to 250 ° C to form a liquid phase. At this time, at least one of PP (polypropylene), PET (polyethylene terephthalate), PE (polyethylene), PS (polystyrene) and ABS (acrylonitrile butadiene styrene) may be selected as the polymer resin. The melting temperature may be different.

항균 기능성 물질 첨가 단계(Step of Adding Antimicrobial Functional Materials ( S20S20 ):):

본 발명의 일 실시예에 의하면, 패각(貝殼)을 고온에서 가열한 후 수분을 첨가함으로써, 항균도가 높은 수산화칼슘(Ca(OH)2)을 포함하는 항균 기능성 물질을 제조하게 된다.According to one embodiment of the present invention, an antimicrobial functional material containing calcium hydroxide (Ca (OH) 2 ) having a high degree of antimicrobial activity is produced by heating the shell at a high temperature and adding water thereto.

먼저, 패각을 분쇄하여 분말화한다(S21). 패각으로는 석화, 전복, 굴, 피조개, 바지락, 가리비 조개, 진주 조개, 꼬막 등의 조개류와, 달걀, 오리알, 타조알과 같은 조류의 알껍질이 선택될 수 있다.First, the shell is pulverized and pulverized (S21). Shells such as petals, abalone, oysters, shellfish, scallops, scallop shells, pearl shells, cockles, and algae eggs such as eggs, ducks, and ostrich eggs can be selected.

다음, 패각 분말을 830℃ ~ 1200℃에서 1시간 ~ 3시간 동안 고열 처리하여 소성 가공한다(S22). 이와 같은 소성 가공에 의해, 패각 분말에 함유된 탄산칼슘(CaCO3)이 산화칼슘(CaO)로 변화하게 된다. 이때, 소성 온도 및 시간이 상기 범위 미만이면 산화칼슘(CaO)이 충분히 생성되지 않으며, 상기 범위를 초과할 경우, 소성로의 구동 시간 및 비용 대비 산화칼슘(CaO)의 증가율이 미미하여 비경제적이다.Next, the shell powder is heat treated at 830 ° C to 1200 ° C for 1 hour to 3 hours, followed by sintering (S22). By such a calcining process, calcium carbonate (CaCO 3 ) contained in the shell powder is changed to calcium oxide (CaO). If the calcination temperature and time are less than the above range, calcium oxide (CaO) is not sufficiently produced. If the calcination temperature and time are above the above range, the rate of increase of calcium oxide (CaO) is insufficient.

이후, 패각 분말의 총 중량 대비 10wt% ~ 20wt%의 물을 패각 분말에 섞는다(S23). 바람직하게는 처음에 5wt% ~ 10wt%의 물을 섞고, 증발 후 다시 5wt% ~ 10wt%의 물을 섞는다.Thereafter, water of 10 wt% to 20 wt%, based on the total weight of the shell powder, is mixed with the shell powder (S23). Preferably, 5 wt% to 10 wt% of water is initially mixed, and 5 wt% to 10 wt% of water is mixed again after evaporation.

이때, 패각 분말의 산화칼슘(CaO)이 물과 접촉하여 수산화칼슘(Ca(OH)2)으로 변화하게 된다. 수산화칼슘(Ca(OH)2)은 강알칼리성으로 pH가 약 12 ~ 13이며, 알칼리(alkali) 환원 능력이 높고 살균, 항균, 탈취 효과 및 식품의 신선도 유지 효과를 갖는 성분이다. At this time, calcium oxide (CaO) of the shell powder is changed into calcium hydroxide (Ca (OH) 2 ) by contact with water. Calcium hydroxide (Ca (OH) 2 ) is strongly alkaline and has a pH of about 12 to 13, has a high alkaline reducing ability, and is a component having an effect of sterilizing, antibacterial, deodorizing and maintaining freshness of food.

즉, 소성 전 패각의 성분은 주로 탄산칼슘(CaCO3)이고, 이것을 소성하면 산화칼슘(CaO)로 변화하게 되는데, 이 산화칼슘(CaO)이 물과 접촉함으로써 수산화칼슘(Ca(OH)2) 수용액이 생성되고, 이 수용액은 강한 알칼리성을 나타내어 수용액 중의 수산화이온(OH)-이 세균의 세포막을 투과하여 세포질을 가수분해함으로써 항균 작용을 발휘하게 되는 것이다.That is, the components of the pre-firing the shell is mainly calcium carbonate (CaCO 3) and, when firing this there is the change in calcium (CaO) oxide, by the calcium oxide (CaO) is in contact with water, calcium hydroxide (Ca (OH) 2) aqueous solution (OH) - in the aqueous solution permeates the bacterial cell membrane and hydrolyzes the cytoplasm to exhibit an antibacterial action.

한편, 10wt% 미만의 물을 섞는 경우에는 수산화칼슘(Ca(OH)2)이 충분히 생성되지 않으며, 20wt%를 초과하여 물을 섞는 경우에는 물의 공급양 대비 수산화칼슘(Ca(OH)2) 생성량의 증가폭이 미미하여 경제성이 떨어진다.On the other hand, when mixing is less than 10wt% water, calcium hydroxide (Ca (OH) 2) is not enough to produce, in excess of 20wt% when mixing the water compared to the amount of water supplied to the calcium hydroxide (Ca (OH) 2) increment of production The economy is poor.

이후, 패각 분말을 입경 0.1㎛ ~ 10㎛로 분쇄하여 항균 기능성 물질의 제조를 완료한다(S24). 패각 분말의 입경이 0.1㎛ 미만이면 그 크기 감소율 대비 항균 성능이나 분산성의 향상 효과가 없어 비경제적이며, 10㎛를 초과하는 경우에는 분산성이 저하된다.Thereafter, the shell powder is pulverized into particles having a particle size of 0.1 mu m to 10 mu m to complete the production of the antibacterial functional material (S24). If the particle size of the shell powder is less than 0.1 탆, the antibacterial activity or the dispersibility is not improved compared with the size reduction ratio, which is uneconomical. If the particle size exceeds 10 탆, the dispersibility is lowered.

이때, 평균 입경의 균일화를 위해, 패각 분말에 0.5wt% ~ 5wt%의 실리카(SiO2) 분말을 혼합하는 것이 바람직하다. 실리카(SiO2)는 패각 분말 사이의 재결합을 최소한으로 억제하여 평균 입경을 균일하게 하는 역할을 하며, 분산성 등을 고려하여 실리카(SiO2)의 크기는 1㎛ ~ 30㎛인 것이 바람직하다. At this time, for the purpose of making the average particle size uniform, it is preferable to mix the powder of silica with 0.5 wt% to 5 wt% of silica (SiO 2 ). Silica (SiO 2 ) plays a role of minimizing recombination between shell powders and making the average particle size uniform, and it is preferable that the size of silica (SiO 2 ) is 1 탆 to 30 탆 in consideration of dispersibility and the like.

이와 같이 제조된 항균 기능성 물질을 액상의 고분자 수지에 첨가하여 액상 혼합물을 제조한다. 이때, 액상 혼합물은 고분자 수지 65wt% ~ 97wt%와 항균 기능성 물질 3wt% ~ 35wt%를 포함하는 것이 바람직한데, 항균 기능성 물질이 3wt% 미만이면 항균 효과가 미미하고, 35wt%를 초과하면 항균 기능성 물질의 증가량에 비해 항균 효과의 향상이 미미하여 경제성이 떨어지기 때문이다.The antibacterial functional material thus prepared is added to the liquid polymer resin to prepare a liquid mixture. At this time, the liquid mixture preferably contains 65wt% to 97wt% of the polymer resin and 3wt% to 35wt% of the antibacterial functional material. When the antibacterial functional material is less than 3wt%, the antibacterial effect is insignificant. When the antibacterial functional material exceeds 35wt% The improvement of the antimicrobial effect is insignificant compared to the increase of the amount of the antioxidant.
