The vacuum insulation material (vacuum insulation panel) was enclosed and built, but the folding type structure of the vacuum insulation material and bag was developed to reduce the volume by folding the bag as a whole.
종래기술의 가방은 내부에 스티로폼이나 진공단열재를 배치하여 단열 성능을 부여한 제품들은 있으나, 가방의 내외부 열전달을 차단하여 단열 성능을 충분히 발휘하기에는 많은 문제가 있었다.In the prior art bag, there are products in which a styrofoam or vacuum insulation material is placed inside to impart insulation performance, but there are many problems in sufficiently exerting the insulation performance by blocking heat transfer inside and outside the bag.
본 발명은 진공단열재를 가방의 내부에 넣고 봉재한 것으로, 내부의 진공단열재 및 가방을 동시에 접을 수 있는 구조를 제공하여 내외부 열교환을 차단하면서도 가방을 간편하게 접을 수 있는 기술을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a structure in which a vacuum insulator and a bag can be folded at the same time by blocking the heat exchange between the inside and the outside, while providing a technology to easily fold the bag.

본 발명의 목적, 특정한 장점들 및 신규한 특징들은 첨부된 도면들과 연관되는 이하의 상세한 설명과 바람직한 실시예로부터 더욱 명백해질 것이다. 또한, 사용된 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로써, 이는 사용자 운용자의 의도 또는 관례에 따라 달라질 수 있다. 그러므로 이러한 용어들에 대한 정의는 본 명세서의 전반에 걸친 내용을 토대로 내려져야 할 것이다.The objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments associated with the accompanying drawings. In addition, the terms used are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of the user operator. Therefore, definitions of these terms should be made based on the contents of the present specification.
진공단열재는 대기압의 힘을 견뎌내고 내부 공간 (두께)를 형성하여 실질적으로 단열을 하는 심재, 심재를 감싸며 진공을 유지하도록 외부 공기를 차단하는 외피재, 그리고 잔류 가스나 침투 가스를 화학적으로 흡착, 제거하여 진공도 파괴를 지연시키는 흡착제로 구성된다.Vacuum insulation material withstands the force of atmospheric pressure and forms an internal space (thickness) to substantially insulate the core material, envelopes the core material and blocks the external air to maintain vacuum, and chemically adsorbs and removes residual gas or infiltration gas Thus, the vacuum is also composed of an adsorbent that delays destruction.
본 발명의 심재는 글라스울, 흄드 실리카, 유기섬유 (폴리에스터, 폴리프로필렌 등) 중 하나로 구성될 수 있으나, 용도가 식품 포장일 경우에는 유기섬유가 바람직하다. 진공단열재가 외부 힘으로 강제 파괴되면 내부 심재가 노출될 수 있기 때문이다.The core material of the present invention may be composed of one of glass wool, fumed silica, and organic fibers (polyester, polypropylene, etc.), but the organic fiber is preferable when the use is food packaging. This is because if the vacuum insulating material is forcibly destroyed by external force, the inner core material may be exposed.
외피재는 앞면과 뒷면이 서로 다른 재질인 하이브리드 타입이 바람직하다. 외피재는 알루미늄 호일 (6~7 micron)이 포함된 호일 외피재와, 알루미늄이 50 ~ 100nm (0.05~0.1 micron) 증착 코팅된 증착 외피재와, 알루미늄 없이 무기투명증착, 유기투명증착 등으로 기체를 차단하는 비금속 투명 외피재 중 1개 이상을 채택하여 구성된다. 알루미늄 호일 외피재는 두꺼운 알루미늄 차단층이 존재하여, 기체를 아주 강력하게 차단할 수 있는 장점이 있다. 하지만 양면을 모두 알루미늄 호일 외피재로 구성할 경우, 알루미늄의 높은 열전도도로 인해 외피재를 타고 열이 내측에서 외측으로 흘러가 버리는 ‘열교 현상＇이 심하게 발생하여, 진공단열재의 의미가 퇴색되기 때문에 바람직하지 않다. The outer cover material is preferably a hybrid type having different materials on the front and back sides. The outer cover material is a foil cover material containing aluminum foil (6~7 micron), a vapor coated outer material coated with aluminum 50~100nm (0.05~0.1 micron), and inorganic transparent vapor deposition without aluminum, organic transparent vapor deposition, etc. It is constructed by adopting one or more of the non-metallic transparent sheathing material to block. The aluminum foil outer material has the advantage of being able to block the gas very strongly because a thick aluminum barrier layer is present. However, if both sides are made of aluminum foil sheath, it is not desirable because the high thermal conductivity of aluminum causes the heat bridge to flow from the inside to the outside, causing a severe'thermal bridge phenomenon' and the meaning of the vacuum insulation material is faded. not.
알루미늄 증착 외피재나 비금속 투명 외피재는 알루미늄 호일의 부재로 인해 상대적으로 기체 차단능이 떨어지나, ‘열교 현상＇을 거의 완벽하게 차단할 수 있다는 장점이 있다. 따라서, 한 쪽면은 알루미늄 호일 외피재로, 나머지 한 쪽면은 증착 외피재 혹은 비금속 투명 외피재로 구성하여, 기체 차단과 열교 현상 제거를 모두 확보할 수 있다. 흡착제는 기본적으로 산화칼슘 (CaO)가 필수 요소로 포함되고, 기타 산소나 수소를 흡착하게 위해 산화티타늄, 산화세륨, 산화구리, 산화마그네슘, 산화바륨 등이 추가되기도 한다.Aluminum-deposited or non-metallic transparent sheathing materials have the advantage of being able to block the “thermal bridge phenomenon” almost completely, although the gas barrier performance is relatively low due to the absence of aluminum foil. Therefore, one side is made of an aluminum foil sheath, and the other side is made of an evaporated sheath or a non-metallic transparent sheath, thereby ensuring both gas barrier and thermal bridge removal. The adsorbent basically contains calcium oxide (CaO) as an essential element, and titanium oxide, cerium oxide, copper oxide, magnesium oxide, and barium oxide may be added to adsorb oxygen or hydrogen.
본 발명은 접이식 가방 내부에 진공단열재를 배치하되 내외측을 천재질로 감싼 상태에서 봉재하는 방식으로 가방의 내부에 장착하여, 가방의 내부와 외부의 열전달을 차단한 것입니다.The present invention is to block the heat transfer inside and outside of the bag by placing the vacuum insulation material inside the foldable bag, but mounting the inside and outside of the bag in a manner that the inside and outside are wrapped in a natural material.
도 1에서 도 6은 본 발명의 일 실시예에 따른 접이식 가방에 내장되는 진공단열재가 접히는 과정을 보여주는 모습이며, 도 7에서 도 12는 본 발명의 일 실시예에 따른 접이식 가방이 접히는 과정을 보여주는 모습이다.1 to 6 are views showing a process of folding a vacuum insulation material embedded in a folding bag according to an embodiment of the present invention, and FIGS. 7 to 12 show a process of folding a folding bag according to an embodiment of the present invention. It looks like.
도 1은 본 발명에서 사용되는 진공단열재의 모습이며, 도 2는 상기 진공단열재의 측면부를 세운 모습이다. 도 3과 도 4는 상기 진공단열재의 내부에 디바이더를 추가한 모습이며, 디바이더는 2개 내지 3개 정도 추가 가능하며 내부공간을 분할할 필요가 있을 때 적절한 곳에 사용할 수 다.1 is a state of the vacuum insulating material used in the present invention, Figure 2 is a state in which the side portion of the vacuum insulating material. 3 and 4 is a state in which a divider is added to the inside of the vacuum insulating material, and two to three dividers can be added and can be used where appropriate when it is necessary to divide the interior space.
상기 디바이더가 내부공간을 분할할 필요가 없을 경우에는 도 5에 도시된 바와 같이, 상기 디바이더를 양측단에 배치하여 측면의 열교환을 차단하여 단열을 강화할 수 있다. 도 6은 상기 진공단열재의 상측에 뚜껑을 추가한 모습이며,When the divider does not need to divide the interior space, as shown in FIG. 5, the dividers are disposed at both ends to block heat exchange on the side to enhance insulation. 6 is a state in which a lid is added to the upper side of the vacuum insulation material,
도 7은 본 발명의 일 실시예에 따른 접이식 가방으로 내부에는 상기 진공단열재를 내장한 상태로 봉재한 상태이어서 진공단열재는 보이지 않으며, 진공단열재는 가방의 상하면과 4개의 측면에 모두 구비되어 있다.7 is a foldable bag according to an embodiment of the present invention, the inside of which is sealed with the vacuum insulation material embedded therein, so that the vacuum insulation material is not visible, and the vacuum insulation material is provided on both the upper and lower surfaces of the bag and the four sides.
본 발명의 접이식 가방을 접기 위해서는 먼저 도 8에 도시된 바와 같이, 상기 접이식 가방에서 바닥부를 일측을 기준으로 상측으로 들어서 회동하시켜서 한쪽 측면에 인접하게 배치한다. 그리고, 도 9와 도 10에 도시한 바와 같이, 접이식 가방의 마주보는 두 측면 중앙이 안측으로 들어가면서 접히게 되면서 다른 마주보는 두 측면이 서로 맞닿으면서 접히게 된다.In order to fold the folding bag of the present invention, first, as shown in FIG. 8, the bottom portion of the folding bag is lifted upwards relative to one side and rotated to be disposed adjacent to one side. And, as shown in Figs. 9 and 10, the two opposite sides of the folding bag are folded while entering the inner side, and the two opposite sides are folded while touching each other.
도 11과 도 12는 상기 접이식 가방에 벨트가 구비되어 실제 사용되는 사용상태도를 도시하고 있는데, 상기 디바이더는 벨크로를 사용하여 가방 내부에서 좌우로 위치를 이동시킬 수 있어서 내부 공간 구획에 필요한 크기 만큼 적절히 조절할 수 있다.11 and 12 show a state of use in which the folding bag is equipped with a belt, and the divider can move its position from side to side inside the bag using a Velcro, so that it is appropriate for the size required for the interior space partition. Can be adjusted.
본 발명의 접이식 가방은 내부 육면에 진공단열재를 구비하여 가방의 내부와 외부가 열이 새는 것을 차단하면서 동시에 가방을 접어서 보관할 수 있으며 또한 필요한 크기로 내부공간을 구획할 수 있는 방법을 제공한다.The foldable bag of the present invention is provided with a vacuum insulating material on the inner six sides, while preventing the heat from leaking inside and outside of the bag, and at the same time, the bag can be folded and stored, and also provides a method for dividing the inner space into a required size.
진공단열재를 구비한 디바이더를 이용하여 가방의 내부공간을 구획함으로써, 가방의 내부에서 서로 다른 온도를 유지할 수 있는 이점도 있다. 내용식품과 냉장식품을 가방에 담아서 배달하거나 기타 휴대하는 경우를 생각해 보면, 냉장용과 냉동용은 유지되어야 하는 온도가 상이하기 때문에 이들 사이에도 열교환을 차단할 필요가 있다. 즉, 가방의 구획된 공간 중 하나의 공간에는 냉장식품을 보관하고, 다른 공간에는 냉동식품을 보관하여 냉동식품의 낮은 온도가 냉장식품에 영향을 주지 않도록 하는 것이다. 본 발명의 가방은 상기 디바이더 자체 내부에 진공단열재를 배치하여 이러한 기능을 발휘하는 것이다.By dividing the inner space of the bag using a divider equipped with a vacuum insulating material, there is also an advantage of maintaining different temperatures inside the bag. Considering the case of delivering contents or refrigerated food in a bag or carrying it, it is necessary to block heat exchange between refrigeration and refrigeration because the temperatures to be maintained are different. That is, in one of the compartments of the bag, the refrigerated food is stored in one space, and the frozen food is stored in the other space so that the low temperature of the frozen food does not affect the refrigerated food. The bag of the present invention exhibits this function by arranging a vacuum insulating material inside the divider itself.
