Description
본 발명은 금속캔에 관한 것으로, 식품에서 발생하는 가스를 배출하는 멤브레인 필터가 구비된 금속캔에 관한 것이다.The present invention relates to a metal can, and to a metal can equipped with a membrane filter for discharging gas generated from food.
일반적으로 금속캔과 같은 저장수단에 저장되어 유통되는 음식물 가운데 김치, 된장, 고추장, 젓갈 등과 같은 발효식품은 제품의 특성상 포장 및 유통과정에서 지속적으로 발효가 진행된다.In general, fermented foods such as kimchi, soybean paste, red pepper paste, and salted fish among foods stored and distributed in storage means such as metal cans are fermented continuously during the packaging and distribution process due to the characteristics of the product.
이때, 발효식품에서는 유기화합물의 분해로 인하여 탄산가스가 발생하는데, 이는 발효식품의 맛을 변질시킴은 물론, 저장수단 내부의 압력을 증가시켜 저장수단을 팽창시키거나, 심할 경우 저장수단의 파손을 야기하여 제품의 품질을 저하시키는 문제점이 있었다.At this time, carbon dioxide gas is generated in fermented food due to the decomposition of organic compounds, which not only changes the taste of the fermented food, but also increases the pressure inside the storage means to expand the storage means, or in severe cases damage the storage means. There was a problem of lowering the quality of the product by causing it.
또한, 멸균이 안 된 신선식품도 가스가 발생한다.In addition, fresh food that has not been sterilized also generates gas.
따라서, 종래에는 상기와 같은 문제점을 해결하기 위하여, 소포제 혹은 가스흡착제를 발효식품과 함께 저장수단 내에 동봉하여 식품으로부터 발생하는 가스를 제거하거나, 저장수단에 체크밸브 형태의 가스배출수단을 별도 구비하여 사용자가 가스배출수단을 작동시켜 저장수단 내부의 가스를 외부로 배출시키는 방법이 활용되었다.Therefore, in the prior art, in order to solve the above problems, an antifoaming agent or a gas adsorbent is enclosed in a storage means together with the fermented food to remove gas generated from the food, or a gas discharge means in the form of a check valve is separately provided in the storage means. A method in which the user operates the gas discharge means to discharge the gas inside the storage means to the outside was used.
그러나 소포제나 가스흡착제와 같은 화학제품은 발효식품에 직접적으로 노출된 상태로 저장수단에 수용되기 때문에, 제품을 개봉하였을 때 소포제나 가스흡착제가 시각적으로 노출되어 미감을 훼손시키고, 이로 인해 소비자로 하여금 제품에 이질감이 들게 하여 소비욕구를 저하시키는 문제점이 있었다.However, since chemical products such as antifoaming agents and gas adsorbents are stored in storage means directly exposed to fermented food, the defoaming agent or gas adsorbent is visually exposed when the product is opened, thereby damaging the aesthetics, which causes consumers to There was a problem of lowering consumer desire by creating a sense of heterogeneity in the product.
또한, 소포제나 가스흡착제의 경우, 외부충격 혹은 포장불량 등의 이유로 인하여 포장지 내부의 화학물질이 외부로 유출될 가능성이 있고, 이는 제품의 원가손실로 이어지는 문제점이 있었다.In addition, in the case of an antifoaming agent or a gas adsorbent, there is a possibility that chemicals inside the packaging paper may be leaked to the outside due to external shock or poor packaging, which leads to a cost loss of the product.
그리고 체크밸브 형태의 가스배출수단을 저장수단에 형성할 경우, 제조 공정의 추가로 인하여 생산성이 저하됨은 물론, 제조비용을 상승시키는 문제점이 있었다.And, when the gas discharge means in the form of a check valve is formed in the storage means, there is a problem in that productivity is lowered due to the addition of the manufacturing process, as well as increasing the manufacturing cost.
따라서, 보다 복합적이고 개선된 형태의 멤브레인 필터가 구비된 금속캔의 개발이 요구되고 있는 실정이다.Accordingly, there is a demand for the development of a metal can equipped with a more complex and improved type of membrane filter.
본 발명은 전술한 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 식품에서 발생된 가스는 배출하고 외부 신선한 공기는 유입되어 식품이 항상 신선하게 유지되는 멤브레인 필터가 구비된 금속캔을 제공하는데 있다.The present invention has been devised to solve the above-mentioned problems in the prior art, and an object of the present invention is to discharge gas generated from food and introduce fresh air from outside to keep food always fresh. is to provide
상기와 같은 목적을 달성하기 위한 본 발명의 멤브레인 필터를 구비한 금속캔은, 식품을 수용하기 위한 수용부와 수용부를 마감하는 뚜껑으로 구성된 금속캔; 및 상기 뚜껑의 내측에 부착된 멤브레인 필터를 포함하는 것을 특징으로 한다.In order to achieve the above object, a metal can having a membrane filter of the present invention includes: a metal can comprising a accommodating part for accommodating food and a lid closing the accommodating part; and a membrane filter attached to the inside of the lid.
또한, 상기 뚜껑에는 관통홀이 형성되며, 상기 멤브레인 필터는 관통홀의 덮는 크기로 형성된거나 상기 뚜껑의 저면을 모두 덮는 크기로 형성된 것을 특징으로 한다.In addition, a through hole is formed in the lid, and the membrane filter is formed to have a size to cover the through hole or to cover all of the bottom surface of the lid.
또한, 상기 멤브레인 필터는 가스는 배출하고 외부공기는 유입되는 것을 특징으로 한다.In addition, the membrane filter is characterized in that gas is discharged and external air is introduced.
또한, 상기 멤브레인 필터는 식품의 액체는 배출되지 않도록 구성된 것을 특징으로 한다.In addition, the membrane filter is characterized in that the food liquid is configured not to be discharged.
본 발명에 따른 멤브레인 필터를 구비한 금속캔에 따르면, 금속캔의 관통홀에 설치된 멤브레인 필터에 의해 식품에서 발생된 가스는 배출하고 외부 신선한 공기는 유입되어 식품이 항상 신선하게 유지되는 효과를 제공한다.According to the metal can having a membrane filter according to the present invention, the gas generated from the food is discharged by the membrane filter installed in the through hole of the metal can and fresh air is introduced to provide the effect that the food is always kept fresh. .
이에 따라, 소포제나 가스흡착제와 같은 화학제품을 원천적으로 배제함으로써, 내부에 저장된 음식물의 오염을 예방함은 물론, 제품의 미감을 향상시켜 소비자로 하여금 소비욕구를 증대시킬 수 있다.Accordingly, by fundamentally excluding chemical products such as antifoaming agents or gas adsorbents, it is possible to prevent contamination of food stored therein, as well as improve the aesthetics of the product, thereby increasing the consumer's desire for consumption.

도 2는 본 발명에 따른 멤브레인 필터를 구비한 금속캔의 도시한 도면이다.1 is a view showing the configuration of a metal can having a membrane filter according to the present invention.
2 is a view showing a metal can having a membrane filter according to the present invention.
이하, 본 발명의 바람직한 실시 예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 멤브레인 필터를 구비한 금속캔의 구성을 도시한 도면이고, 도 2는 본 발명에 따른 멤브레인 필터를 구비한 금속캔의 도시한 도면이다.1 is a diagram illustrating the configuration of a metal can having a membrane filter according to the present invention, and FIG. 2 is a diagram illustrating a metal can having a membrane filter according to the present invention.
도 1 내지 도 2에 도시한 바와 같이, 본 발명에 따른 멤브레인 필터를 구비한 금속캔은, 식품을 보관하기 위한 캔본체와, 캔본체의 마감된 단부를 마감하는 뚜껑으로 구성된다. 즉 공지의 "투-피스(two-piece)" 금속캔이다.1 to 2, a metal can with a membrane filter according to the present invention includes a can body for storing food, and a lid for closing the finished end of the can body. That is, the known "two-piece" metal can.
또한, 뚜껑에는 사용자가 파지하는 손잡이가 구비되며, 뚜껑의 일부에는 절취선이 형성된다. 이에 따라 사용자가 손잡이를 파지하고 눌렀다 들어올리면 뚜껑은 절취선을 따라 개봉된다.In addition, the lid is provided with a handle gripped by the user, a part of the lid is formed with a perforated line. Accordingly, when the user grips the handle, presses and lifts it, the lid is opened along the perforation line.
이러한, 금속캔은 원래 장기보존식품용인데 재질이 스틸이라 열전도율이 높아 외부온도 변화에 작게 반응하며 일정한 온도를 유지할 수 있는 장점이 있다.These metal cans are originally for long-term storage food, but because they are made of steel, they have high thermal conductivity, so they respond small to changes in external temperature and have the advantage of being able to maintain a constant temperature.
그러나, 금속캔에 멸균이 안된 신선식품을 보존하다 보니 식품에서 발생되는 가스를 배출하기 위해 캔뚜껑을 타공후 관통홀을 형성하고, 관통홀에 멤브레인을 부착하였다. However, in order to preserve unsterilized fresh food in a metal can and to discharge gas generated from the food, a through hole was formed after the can lid was drilled, and a membrane was attached to the through hole.
이에 따라, 캔 내부의 가스는 배출하고 외부의 신선한 공기는 들어와 캔내부의 식품이 항상 신선하게 유지된다는 장점이 있다.Accordingly, gas inside the can is exhausted, and fresh air from the outside comes in, and the food inside the can is always kept fresh.
구체적으로, 본 발명의 멤브레인 필터가 구비된 금속캔은, 식품을 수용하기 위한 수용부와 수용부를 마감하는 뚜껑으로 구성된 금속캔 및 상기 뚜껑의 내측에 부착된 멤브레인 필터로 구성된다.Specifically, the metal can equipped with the membrane filter of the present invention is composed of a metal can including a accommodating part for accommodating food and a lid closing the accommodating part, and a membrane filter attached to the inside of the lid.
또한, 상기 뚜껑에는 관통홀이 형성되며, 상기 멤브레인 필터는 관통홀의 덮는 크기로 형성된거나 상기 뚜껑의 저면을 모두 덮는 크기로 형성된다.In addition, a through hole is formed in the lid, and the membrane filter is formed to have a size to cover the through hole or to cover all of the bottom surface of the lid.
그리고, 상기 멤브레인 필터는 가스는 배출하고 외부공기는 유입된다.In addition, the membrane filter discharges gas and introduces outside air.
한편, 상기 멤브레인 필터는 식품의 액체는 배출되지 않도록 구성된다.On the other hand, the membrane filter is configured so that the liquid of the food is not discharged.
이때, 상기 멤브레인 필터는 상아프론테크의 'ePTFE for Textile'이 적용된다. 'ePTFE for Textile'은 ㎠당 수억개의 나노 사이즈 기공을 갖는 Expanded Polytetrafluoroethylene이다. 생성된 나노사이즈 기공은 증기입자(1nm이하)는 배출하고, 물입자(500㎛)의 침투를 막아 준다.In this case, Sanga Frontek's 'ePTFE for Textile' is applied to the membrane filter. 'ePTFE for Textile' is Expanded Polytetrafluoroethylene with hundreds of millions of nano-sized pores per cm2. The generated nano-sized pores discharge vapor particles (less than 1 nm) and prevent penetration of water particles (500 μm).
본 발명에 따르면, 금속캔의 관통홀에 설치된 멤브레인 필터에 의해 식품에서 발생된 가스는 배출하고 외부 신선한 공기는 유입되어 식품이 항상 신선하게 유지되는 효과를 제공한다.According to the present invention, the gas generated from the food is discharged by the membrane filter installed in the through hole of the metal can and fresh air is introduced to provide the effect that the food is always kept fresh.
이에 따라, 소포제나 가스흡착제와 같은 화학제품을 원천적으로 배제함으로써, 내부에 저장된 음식물의 오염을 예방함은 물론, 제품의 미감을 향상시켜 소비자로 하여금 소비욕구를 증대시킬 수 있다.Accordingly, by fundamentally excluding chemical products such as antifoaming agents or gas adsorbents, it is possible to prevent contamination of food stored therein, as well as improve the aesthetics of the product, thereby increasing the consumer's desire for consumption.
이상, 본 발명의 바람직한 실시 예에 대하여 상세히 설명하였으나, 본 발명의 기술적 범위는 전술한 실시 예에 한정되지 않고 특허청구범위에 의하여 해석되어야 할 것이다. 이때, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 발명의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 고려해야 할 것이다.As described above, preferred embodiments of the present invention have been described in detail, but the technical scope of the present invention is not limited to the above-described embodiments and should be interpreted according to the claims. At this time, those skilled in the art should consider that many modifications and variations are possible without departing from the scope of the present invention.
