Description

아이스팩{ICE PACK}Ice Pack {ICE PACK}

본 발명은 음식물 등의 변질을 막기 위해 냉장보온 환경를 만들어 주는 아이스팩에 관한 것이다.The present invention relates to an ice pack that creates a cold storage environment to prevent deterioration of food and the like.

종래의 아이스팩으로서 용기 내부에 고흡수성 폴리머재를 소량 주입하고 여기에 물을 주입하여 상기 고흡수성 폴리머재가 팽창하여 겔(gel) 상태로 되게 함으로써 얻어지는 것은, 가격이 저렴하고 재사용이 가능하다는 장점이 있는 반면 폐기하고자 할 경우에는 내용물과 팩 용기를 분리하지 못하고 전체를 폐기처분하여야 함에 따라 환경오염의 원인이 된다는 문제가 있었다.What is obtained by injecting a small amount of a super absorbent polymer material into a container as a conventional ice pack and injecting water therein so that the super absorbent polymer material expands to a gel state is cheap and reusable. On the other hand, in the case of disposal, there was a problem that the contents and the pack container could not be separated and the whole should be disposed of, causing environmental pollution.

그러한 반면, 종래의 아이스팩으로서 부직포, 스펀지 등의 재질로 이루어진 블록 형태의 흡수체를 용기 내부에 주입하고 여기에 물을 주입하여 상기 흡수체에 흡수시킴으로써 얻어지는 것은, 친환경 아이스팩으로서 재사용은 물론 폐기시 내용물과 용기를 분리하여 재활용할 수 있다는 장점이 있는 반면 비교적 고가로서 경제성이 떨어지는 문제, 외부충격으로 인해 용기가 터질 수가 있으므로 이로 인해 내부의 물이 새어나와 냉장 대상인 제품의 변질 내지 손상을 유발한다는 문제가 있었다.On the other hand, as a conventional ice pack, what is obtained by injecting a block-shaped absorbent made of a material such as a non-woven fabric or a sponge into a container and injecting water therein to absorb the absorbent, is an eco-friendly ice pack, as well as reuse and disposal of contents and containers While there is an advantage of being able to separate and recycle, there is a problem that the economical property is relatively expensive and the container may burst due to external impact, thereby causing water to leak out and cause deterioration or damage of the product to be refrigerated.

한편, 상기 2 종류의 아이스팩의 문제점들을 동시에 해결하기 위해 전분을 함유한 아이스팩이 제안되기는 하였으나, 세균번식률이 높은 관계로 특히 폐기시 하수구의 세균번식 및 악취발생 원인이 되었다.
On the other hand, to solve the problems of the two types of ice packs at the same time, ice packs containing starch have been proposed, but due to the high rate of bacterial propagation, they caused germs and odors in sewers during disposal.

Patent registration No. 10-0758655 (Registration date: 2007.09.07.)

따라서, 본 발명의 목적은 상기한 종래기술에 따른 아이스팩의 문제점들을 동시에 해결할 수 있는 것으로서 경제적이면서도 친환경적이며 아울러 세균번식 문제까지 해결할 수 있는 아이스팩을 제공하는 데 있다.Accordingly, an object of the present invention is to provide an ice pack that can simultaneously solve the problems of the ice pack according to the prior art and is economical, environmentally friendly, and also solves the problem of bacterial propagation.

상기 목적을 달성하기 위해 본 발명은 플라스틱 또는 합성수지 재질의 용기에 내용물이 수용되는 아이스팩에 있어서, 상기 내용물은 분말한천과 물의 혼합물인 것을 특징으로 하는 아이스팩을 제공한다.In order to achieve the above object, the present invention provides an ice pack in which the contents are accommodated in a container made of plastic or synthetic resin, wherein the contents are a mixture of powder agar and water.

여기서, 상기 내용물은, 상기 용기의 용량이 350ml인 경우에 상기 분말한천은 5~7g 투입되고 나머지로서 상기 물이 투입됨으로써 얻어지고, 상기 용기의 용량이 500ml인 경우에 상기 분말한천은 7~10g 투입되고 나머지로서 상기 물이 투입됨으로써 얻어지는 구성을 취할 수도 있다.Here, the contents are obtained by adding 5 to 7 g of the powder agar when the capacity of the container is 350 ml and adding the water as the rest, and when the capacity of the container is 500 ml, the powder agar is 7 to 10 g. It is also possible to take a configuration obtained by injecting and adding the water as the rest.

이 경우, 상기 용기의 용량이 350ml인 경우에 상기 분말한천은 5~6g 투입되고 나머지로서 상기 물이 투입되며, 상기 용기의 용량이 500ml인 경우에 상기 분말한천은 7~9g 투입되고 나머지로서 상기 물이 투입되는 구성을 취할 수도 있다.In this case, when the capacity of the container is 350ml, the powder agar is added 5-6g and the water is added as the rest, and when the capacity of the container is 500ml, the powder agar is added 7-9g and the rest as the It is also possible to take a configuration in which water is added.

또는, 상기 용기의 용량이 350ml인 경우에 상기 분말한천은 6~7g 투입되고 나머지로서 상기 물이 투입되며, 상기 용기의 용량이 500ml인 경우에 상기 분말한천은 9~10g 투입되고 나머지로서 상기 물이 투입되는 구성을 취할 수도 있다.Alternatively, when the capacity of the container is 350ml, the powder agar is added in the amount of 6-7g and the water is added as the rest. When the capacity of the container is 500ml, the powder agar is added in the amount of 9-10g and the water as the rest. It is also possible to take a configuration in which this is input.

한편, 상기 물은 50~100℃인 것을 선택하여 사용할 수도 있으며, 필요에 따라 상기 물은 상온 이하의 냉수인 것을 선택하여 사용할 수도 있다.On the other hand, the water may be used to select 50 ~ 100 ℃, if necessary, the water may be used to select the cold water below room temperature.

이상과 같이, 본 발명에 따른 아이스팩에 의하면 분말한천이 인체 등에 무해한 천연재료이면서도 곰팡이나 세균번식이 이루어지지 않는 100% 친환경 제품이므로 폐기 시 처리가 간편하다. 즉, 아무런 첨가제가 들어가지 않는 내용물을 단지 용기에서 빼내어 물 버리듯이 어디에나 버릴 수 있고 상기 용기는 재활용이 가능하다. 분말한천이 물을 흡수하여 겔 상태로 되어 얼려 사용된 후에 다시 녹으면 물처럼 상태가 변하게 된다.As described above, according to the ice pack according to the present invention, powdered agar is a natural material that is harmless to the human body, but is 100% eco-friendly product that does not cause mold or germ reproduction, so it is easy to dispose of when discarded. That is, the contents without any additives can be removed from the container and thrown away as if to be discarded, and the container is recyclable. The powder agar absorbs water, becomes a gel, freezes and melts again, and then changes into water.

또한, 물과 혼합되는 분말한천은 상기 물을 흡수하여 겔 상태가 되어 형태를 유지하게 되므로 사용중 용기가 터지는 경우에도 냉장 대상인 제품의 변질 내지 손상을 유발하지 않는다.In addition, the powder agar mixed with water absorbs the water and becomes a gel state to maintain its shape, and thus does not cause deterioration or damage of the product to be refrigerated even if the container bursts during use.

또한, 기존 폴리머재가 주입된 아이스팩보다 상온에서 장시간(5시간 vs 6시간) 형태를 유지할 수 있다.In addition, it is possible to maintain a long time (5 hours vs. 6 hours) form at room temperature than the ice pack in which the existing polymer material is injected.

또한, 아이스팩 용기 내 분말한천의 투입량을 조절함으로써 비교적 유동적인 겔 상태로 사용하거나 또는 묵과 같이 비교적 단단한 고체상태로 규격화하여 사용할 수도 있다.In addition, by controlling the amount of powder agar in the ice pack container, it can be used in a relatively fluid gel state or can be standardized to a relatively solid solid state such as jelly.

본 발명에 따른 아이스팩은 플라스틱 또는 합성수지 재질의 용기에 내용물이 수용된 것으로서 상기 내용물은 분말한천과 물의 혼합물인 것을 특징으로 한다.The ice pack according to the present invention is characterized in that the contents are accommodated in a container made of plastic or synthetic resin, and the contents are a mixture of powder agar and water.

한천(agar)은 바다에서 자라는 우뭇가사리를 뜨거운 물로 끓여 추출시킨 끈적한 액을 여과-응고-동결-용해-탈수-건조의 과정을 여러차례 반복하여 만든 천연식품으로서 이를 분말형태로 제조한 것을 분말한천(powdered agar)이라고 한다.Agar is a natural food made by repeating the process of filtration-coagulation-freezing-dissolving-dehydration-drying several times the sticky liquid extracted by boiling hot water from the sea with hot water and powdered agar (powdered agar) agar).

이때, 상기 내용물은 상기 아이스팩 용기의 용량이 350ml인 경우에 상기 분말한천이 5~7g 투입된 다음 나머지로서 물이 투입됨으로써 얻어진다. 분말한천이 5g 이하, 특히 4g 이하인 경우에는 물과 혼합하여 겔화(gel化)하지 못하는 문제가 있고, 7g 이상인 경우에는 필요 이상으로 딱딱하게 굳어짐으로써 이 또한 아이스팩 내용물로서 부적합하다.At this time, the contents are obtained by adding 5 to 7 g of the powder agar when the capacity of the ice pack container is 350 ml, and then adding water as the rest. If the powder agar is 5g or less, especially 4g or less, there is a problem that it cannot be gelled by mixing with water, and when it is 7g or more, it is also unsuitable as an ice pack content because it hardens more than necessary.

한편, 상기 아이스팩 용기의 용량이 500ml인 경우에는 분말한천이 7~10g 투입되고 나머지로서 물이 투입됨으로써 얻어질 수 있다.On the other hand, when the capacity of the ice pack container is 500ml, it can be obtained by adding 7-10g of powder agar and adding water as the rest.

상기와 같이 아이스팩 용기 내 물과 분말한천을 혼합하여 얻어진 내용물은 겔 상태가 되며, 이것을 냉동시킴으로써 아이스팩으로서 사용할 수 있게 된다.The contents obtained by mixing water and powder agar in the ice pack container as described above are in a gel state, and can be used as an ice pack by freezing them.

이때, 상기 물의 온도를 50~100℃로 가열한 상태에서 투입된 분말한천과 혼합할 경우에는 겔화가 촉진됨으로써 그 즉시 냉동시켜 아이스팩으로 사용할 수 있게 되고, 이와 반대로 즉시 사용할 것이 아니라 재고용으로 비축해두었다가 상당한 기간을 두고 사용하고자 할 경우에는 상온 또는 그 이하의 찬물을 상기 투입된 분말한천에 혼합함으로써 겔화의 속도를 늦출 수 있고, 이로써 재고의 보관기간을 늘릴 수 있다.At this time, when the temperature of the water is mixed with the powdered agar added in a state of heating to 50 to 100°C, gelation is accelerated, so that it can be immediately frozen and used as an ice pack. On the contrary, it is not immediately used but stored for inventory. When using for a period of time, by mixing cold water at or below room temperature with the powder agar, the gelation rate can be slowed down, thereby increasing the storage period of the stock.

한편, 상기에서 아이스팩 용기의 용량이 350ml인 경우 분말한천이 5~6g 투입되고 나머지로서 물이 투입되는 경우, 또는 상기 용기의 용량이 500ml인 경우 분말한천이 7~9g 투입되고 나머지로서 물이 투입되는 경우에는 분말한천의 겔화가 이루어진 후 냉동시에도 비교적 유동적인 겔 상태가 되므로 일반적인 냉장 용도로서 사용할 수가 있다.On the other hand, when the capacity of the ice pack container is 350ml, 5~6g of powder agar is added and water is added as the rest, or when the container capacity is 500ml, 7~9g of powder agar is added and water is added as the rest. If possible, after gelation of the powder agar, it becomes a relatively fluid gel state even during freezing, so it can be used for general refrigeration purposes.

이에 비해 상대적으로, 아이스팩 용기의 용량이 350ml인 경우 분말한천을 6~7g 투입하고 나머지로서 물을 투입하여 혼합한다던가, 또는 아이스팩 용기의 용량이 500ml인 경우 분말한천을 9~10g 투입하고 나머지로서 물이 투입하는 경우 분말한천은 겔화를 넘어 묵과 같이 고체로서의 형태를 유지하게 되므로, 육류를 냉동하는 경우와 같이 일정한 틀 속에서 규격화된 형태의 제품과 아이스팩이 요구되는 경우에는 이처럼 비교적 고동도의 분말한천을 함유시킬 수 있다.On the other hand, when the capacity of the ice pack container is 350 ml, 6-7 g of powder agar is added and water is mixed as the rest, or when the capacity of the ice pack container is 500 ml, 9-10 g of powder agar is added and the remainder is When water is added, the powder agar maintains a solid form like jelly, beyond gelation, so if a product and ice pack in a standard form are required in a certain frame, such as freezing meat, this is a relatively high-density powder. It can contain agar.

이상에서 설명된 아이스팩에 관한 본 발명의 권리범위 내지 기술적 범위는 상기한 바에 따라 한정되는 것이 아니라 후술하는 특허청구범위 및 그 균등범위에 의해 정하여진다.The scope of rights or technical scope of the present invention with respect to the ice pack described above is not limited according to the above, but is defined by the following claims and their equivalents.
